Referring to fig. 9 and 10, fig. 9 is a cross-sectional view of the assembled disc assembly and battery assembly of fig. 3, and fig. 10 is an enlarged view of a portion of region C of fig. 9.
As shown in fig. 10, the fixing assembly 30 includes a screw 32 and a nut 34, the supporting block 120 is provided with a screw groove 124 and a second mounting hole 126 penetrating the screw groove 124, the holding block 240 is provided with a nut groove 244 and a first mounting hole 246 penetrating the nut groove 244, the first mounting hole 246 corresponds to the second mounting hole 126, the nut groove 244 matches the shape of the nut 34, the screw 32 penetrates the second mounting hole 126 and the first mounting hole 246 and is detachably connected to the nut 34, the head of the screw 32 is received in the screw groove 124, and the nut 34 is received in the nut groove 244.
When the chassis assembly 10 and the battery assembly 20 are installed, the battery assembly 20 is lifted from the bottom of the main frame 110, loaded into the accommodating space 114 and moved laterally, the pressing blocks 240 on the side walls of the battery assembly 20 are placed on the supporting blocks 120 on the inner walls of the main frame 110, and then the fixing assemblies 30 are used to connect the pressing blocks 240 and the supporting blocks 120 together, so that the battery assembly 20 is prevented from moving in the horizontal plane, and damage to the battery is avoided.
Specifically, when the chassis assembly 10 and the battery assembly 20 are mounted, the nut 34 in the fixing assembly 30 is a hexagonal nut 34. Firstly, lifting the battery assembly 20 from the bottom of the main frame 110, loading the battery assembly into the accommodating space 114, moving the battery assembly transversely, placing the pressing block 240 on the side wall of the battery assembly 20 on the supporting block 120 on the inner wall of the main frame 110, and placing the hexagon nut 34 into the nut groove 244 on the pressing block 240; retainer ring 36 is then a deformable member, compressing retainer ring 36 through first mounting aperture 246, releasing retainer ring 36 to be disposed in retainer ring receiving groove 248; finally, the screw 32 is inserted into the supporting block 120 from the screw groove 124 of the supporting block 120 and the second mounting hole 126 penetrating the screw groove 124, and the screw 32 is rotated so that the screw 32 is screw-fittingly coupled with the hexagon nut 34 positioned in the nut groove 244. Thereby fixing the pressure holding block 240 and further preventing the battery assembly 20 from moving in the horizontal plane.
The advantage of this mounting is that the weight of the battery assembly 20 directly acts on the mounting surface of the support block 120 of the chassis assembly 10, and the screw 32 attachment only serves to prevent the battery assembly 20 from being displaced, so that the screw 32 is not affected by the weight of the battery assembly 20, and the risk of the screw 32 slipping off the battery assembly 20 is reduced. In addition, the retainer ring 36 can prevent the nut 34 from moving in the axial direction, and avoid the risk of the nut 34 falling off. In other embodiments, because the retainer ring 36 is a deformable member, the retainer ring receiving groove 248 may be eliminated, and the retainer ring 36 is elastically retracted into the first mounting hole 246 and contacts the nut 244.
Referring to fig. 11, fig. 11 is a schematic structural view of a fixing assembly when the chassis assembly and the battery assembly are assembled in fig. 3.
The reason why the hexagon nut 34 is selected is that the nut groove 244 on the pressing block 240 is matched with the hexagon nut 34 due to the profiling structure of the hexagon nut 34, so that when the screw 32 is screwed down, the nut 34 cannot rotate in the counter bore, and the purpose of fixing the screw 32 and the nut 34 in a matched connection manner can be achieved only by rotating the screw 32. The advantage of this type of mounting is that the battery assembly 20 can be easily and quickly replaced.
The retainer ring 36 serves to provide a restraining force to the nut 34 in the axial direction of the nut 34 to prevent the hexagonal nut 34 from falling off the nut groove 244, and the retainer ring 36 is a split retainer ring 36. the split retainer ring 36 is advantageous in that it can be easily removed from the nut groove 244, so that the nut 34 can be replaced after the nut 34 is used for a long time to prevent thread slippage.
