The present invention relates to a vehicle battery module fitting mechanism, and more particularly to a fitting mechanism for fitting a battery module to a frame in a relatively simple manner.

The biggest problem encountered by current electric vehicles is the lack of endurance. Therefore, when the battery runs out, it takes a few hours to charge the battery. Looking at all the published electric vehicles can be seen as almost adding the battery box. On the traditional car chassis structure.

The weight of the battery is not light, so it is necessary to have a rigid enough structure to fix the battery module. The general practice is to connect the battery case to the chassis of the vehicle body or the trunk of the vehicle. This assembly method has at least the following disadvantages: 1. Chassis Too low; 2, the rear weight is too heavy; 3, the chassis is repeated design.

Or, when the battery case is assembled, the battery case is usually first mounted on a connecting component, and then the connecting component is locked to the vehicle body. However, such locking and dismounting operations are usually carried out on site, and the process is very It is cumbersome and is not conducive to the replacement of the battery mode.

In view of the above problems, an object of the present invention is to provide a vehicular battery module fitting mechanism that drives a fitting wedge to engage or release a battery module by a swing mechanism on a frame.

Therefore, in order to achieve the above object, the vehicle battery module fitting mechanism of the present invention includes a body for the battery module combination, and the seat system is fixed on a frame, and the seat body is formed on both sides of the frame. a track, the track is open to the inside of the frame and a fitting wedge and a swinging mechanism are arranged on the track, the engaging wedge is provided with a hook groove toward the inner side of the frame, and the swinging mechanism is coupled to the engaging wedge, and When the swinging mechanism is swung from a first position to a second position, the engaging wedge is displaced from the position of the rail to the non-protruding track. Finally, the battery module is provided with a ratchet block at the edge. When the module is placed in the middle of the two tracks, the ratchet block is fitted into the hook groove by rotating the swinging mechanism to protrude the two engaging wedges to complete the movement of the battery module on the frame. .

In summary, the vehicular battery module fitting mechanism of the present invention determines the fitting or non-mating battery module by operating the swinging mechanism to drive the engaging wedge to protrude or not to protrude the rail, thereby providing a simple mechanism.

When the two rails 12 are in the middle, they are fixed by fitting the battery module 20 by the two fitting wedges 13.

Referring to FIG. 3A and FIG. 3B, in the present invention, the engaging wedge 13 is driven by a swinging mechanism 14. When the swinging mechanism 14 is swung from a first position to a second position, the engaging wedge 13 is The state of the protruding track 12 is displaced to the state in which the track 12 is not protruded, and the battery module 20 is to be hooked by the hook groove 131 on the wedge 13 when the engaging wedge 13 is projected on the track 12. The ratchet block 21 of the battery module 20 can fix the battery module 20 to the frame.

In FIG. 3A and FIG. 3B , it can be seen that in the embodiment, a protrusion 111 is oppositely extended on both sides of the open end of the base 11 , and a protrusion 133 is also disposed on both sides of the engaging wedge 13 . When the wedge 13 protrudes from the rail 12 as shown in FIGS. 3A and 3B, the two projections 133 of the fitting wedge 13 stop against the projections 111 of the base 11. Furthermore, the fitting wedge 13 further includes a lead angle 132 on the same side of the hook groove 131 in addition to the two protrusions 133, and a pull tab 134 is extended on the other side.

In this embodiment, the swinging mechanism 14 includes a rotating shaft 141 and a swinging arm 143. One end of the swinging arm 143 is coupled to the rotating shaft 141, and the other end of the swinging arm 143 is sleeved and coupled to the pulling lug 134 of the engaging wedge 13. When the rotating shaft 141 is rotated, the swing arm 143 is driven to drive the engaging wedge 13 to be displaced.

In addition, a circular cutout 112 is disposed on each side of the corresponding rotating shaft 141 on the base 12 (this figure only presents a lower circular cutout, which does not present an upper circular cutout), and a lateral cutout 113 is further extended on one side of the circular cutout 112, and The rotating shaft 141 is correspondingly extended with a latch 142 inserted in the transverse slit 113.

In the state shown in FIG. 3A and FIG. 3B, the frame 10 has not yet started to mount the battery module 20. At this time, the rotating shaft 141 and the latch 142 are respectively inserted into the circular slit 112 and the transverse slit 113, so the rotating shaft 141. It is impossible to rotate, and at this time, the swing arm 143 pushes the fitting wedge 13 out of the rail 12, and the two protrusions 133 of the fitting wedge 13 stop against the two protrusions 111 of the seat body 11.

Next, as shown in FIG. 4A and FIG. 4B, when the battery module 20 is to be combined, the rotation shaft 141 is first pushed up, and the cassette 142 is disengaged from the transverse slit 113, so that the rotation shaft 141 becomes In the rotated state, the user has to rotate the rotating shaft 141 in the clockwise direction by the tool, and drives the swing arm 143 to interlock the engaging wedge 13 toward the rail 12 without protruding from the rail 12.

Next, as shown in FIGS. 5A to 5B, the battery module 20 is pushed up to the ratchet block 21 corresponding to the hook groove 131 of the fitting wedge 13.
