Description

Technical Field

[0001] The utility model belongs to the technical field of battery mounting racks, and in particular relates to a skateboard-type battery replacement device for a chassis of a new energy vehicle. Background Art

[0002] Battery modules are the power components of new energy equipment such as new energy vehicles. Since there are a large number of battery modules installed on new energy vehicles, most battery modules are integrated and installed on battery brackets, which are installed on the vehicle frame to integrate a large number of battery modules.

[0003] During the use of the battery module, it is necessary to regularly maintain, repair and replace the battery module. Therefore, in order to facilitate replacement, the current conventional battery bracket installation method is to use a slide rail installation. When the battery bracket needs to be removed, the battery bracket is directly slid out. This method not only greatly improves the efficiency of removing and installing the battery bracket, but also greatly reduces the difficulty of removing and installing the bracket.

[0004] However, although the sliding installation method greatly improves the efficiency of bracket disassembly and installation, it also produces negative defects in the actual working process. For example, when the vehicle encounters a bumpy road during operation, the vehicle will jump in the Z direction, causing the battery module to jump. During the jumping or throwing of the battery module, the impact force of the battery is greatly increased, and secondly, it is very easy to cause the electrical connection position of the battery to loosen, and even worse, it is easy to cause the battery to detach from the bracket.

[0005] The above defects are one of the important reasons why the battery cannot work stably, and it is also one of the factors that cause malfunctions in the operation of new energy equipment. Therefore, how to keep the battery bracket easy to disassemble and install, and ensure that the battery installed on the battery bracket is not easy to jump or throw when the car is bumpy, and maintain high stability is of great significance.

[0025] 1. During the working process, the battery bracket mechanism and the battery module installed on the battery bracket mechanism are locked on the track base on the vertical plane through the anti-throw mechanism to prevent them from being thrown.

[0041] Example 1

[0042] like Figure 1-9 As shown, a new energy vehicle chassis skateboard type battery replacement device includes a track mechanism and a battery bracket mechanism rollingly mounted on the track mechanism.

[0043] Specifically, the track mechanism includes a track base 2 spaced apart at the front and rear sides, and a track bar 22 is fixedly connected to the top of the track base 2 .

[0044] Correspondingly, the battery bracket mechanism includes a battery bracket 1, and the bottom of the battery bracket 1 is equipped with a plurality of rollers 14 that roll on the track bar 22. Specifically, the battery bracket 1 includes bracket beams spaced apart at the front and rear sides, and a groove body is provided at the bottom of the bracket beam; the groove body is rotatably connected to a plurality of rollers 14, and the rollers roll on the track bar 22 against each other.

[0045] At the same time, in order to increase the stability of the track mechanism, several free additional track connecting plates 21 are fixed between the bottom of the track base 2. Similarly, the first bracket end connecting plate 11 and the second bracket end connecting plate 12 are fixedly connected to the left and right ends of the bracket beam respectively.

[0046] The battery module is installed between the bracket beams. Specifically, a plurality of battery pack mounting bases 13 are fixedly connected to the battery bracket 1. The battery pack mounting bases 13 are specifically fixedly installed on the bracket beams. The battery module is installed on the battery pack mounting bases 13 in the existing manner.

[0047] At the same time, in order to prevent the battery holder 1 from being thrown when carrying the battery, such as when the new energy vehicle is driving on a bumpy road, the above-mentioned new energy vehicle chassis skateboard type battery exchange device also includes a number of anti-throwing mechanisms 3 for preventing the battery holder 1 from being thrown.

[0048] The anti-throw mechanism 3 is used to lock the battery bracket 1 mechanism and the battery module mounted on the battery bracket 1 mechanism on the track base 2 in a vertical plane to prevent them from being thrown.

[0049] Example 2

[0050] like Figure 1-9 As shown, based on the structure of Example 1, the anti-throw mechanism 3 of this embodiment includes a male mold assembly 331 fixedly mounted on the rail mechanism and a female mold assembly 332 fixedly mounted on the battery bracket 1 mechanism, and the male mold assembly 331 is locked to the matching female mold assembly 332 to lock the battery bracket 1 mechanism.

[0051] Specifically, the male mold assembly 331 includes a rail connecting plate 32 fixedly connected to the rail mechanism (similarly, the rail connecting plate 32 has the same function as the additional rail connecting plate 32, and is also used to increase the stability between the rail bases 2).

[0052] Meanwhile, a punch support 331 is fixedly assembled and connected to the top of the track connecting plate 32 , and a punch 3312 is assembled and connected to the punch support 331 .

[0053] Correspondingly, the die assembly 332 includes a bracket connecting plate 31 fixedly connected to the battery bracket 1 mechanism (specifically, the two ends of the bracket connecting plate 31 are respectively fixedly connected to the side walls of the bracket beam facing each other, and the bracket connecting plate 31 is provided with a mounting port 33 structure adapted to the battery module), the bottom of the bracket connecting plate 31 is fixedly connected to a die bracket 3321, and the die bracket 3321 is assembled with a die 3322 locked on the punch 3312. Specifically, the die 3322 is provided with a pin hole adapted to the punch, so that when the punch 3312 is inserted into the die 3322, locking is achieved, and vice versa. Disengagement is achieved.

[0054] In the actual working process, in order to improve the locking stability, the die bracket 3321-die and the punch bracket 331-punch 3312 are distributed in a staggered manner. For example, one die bracket 3321-die is used to cooperate with the punch bracket 331-punch 3312 on an anti-throw mechanism 3, and two die brackets 3321-die 3322 are used to cooperate with the punch bracket 331-punch 3312 on the adjacent anti-throw mechanism 3. Therefore, a triangular locking structure is formed at adjacent positions to improve the locking effect.

[0055] Through the above method, after the battery module is installed on the battery bracket 1, it is rolled and pushed into the track mechanism, and the multi-point locking is achieved by the cooperation of the die bracket 3321-die 3322 and the punch bracket 331-punch. This solves the technical defect that the battery module and the battery bracket 1 are thrown and jumped in a bumpy state, resulting in reduced battery working stability and potential safety hazards.

[0056] Example 3

[0057] like Figure 1-9 As shown, in this embodiment, based on the structure of embodiment 2, a plug bolt 3313 is threadedly connected to the punch support 331, and the plug bolt 3313 is fixedly connected to the punch 3312. A polyurethane gasket 3314 is sleeved on the punch 3312, and the polyurethane gasket 3314 abuts against the side wall of the punch support 331. The polyurethane gasket is used to increase the stability of the locking connection after the punch 3312 is locked to the die 3322.

[0058] The above-mentioned die support 3321 is threadedly connected with a hexagonal bolt 3323, and the hexagonal bolt 3323 is fixedly connected to the die 3322.

[0059] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
