Description

Technical Field

[0001] The utility model relates to the technical field of battery pack production equipment, in particular to a battery pack processing and fixing device. Background Technique

[0002] As the power source of an electric vehicle, a battery pack usually installs multiple modular batteries inside, and the outer layer of the battery pack can be used to protect the battery modules. Before the battery pack is put on the line, it usually needs to go through relevant national standard tests, such as vibration test, ball impact test, fire test, etc. Among them, the vibration test and the ball impact test are relatively key tests in the battery pack test. In addition to the sufficient structural strength and stiffness requirements of the battery pack itself, the relevant test devices are also particularly crucial.

[0003] At present, during the processing of the existing battery pack, when the fixing device clamps the battery pack, the battery pack is usually arranged on a substrate, and then the fixing device is used to clamp the battery pack. Among them, during the clamping process, the battery pack will move with the fixing device, so that friction occurs between the battery pack and the substrate, resulting in scratches on the surface layer of the battery pack. At the same time, when the fixing device clamps battery packs of different sizes, it is also necessary to adjust the contraction position of the fixing device, so that the applicability of the fixing device is relatively low. Content of the Utility Model

[0004] The purpose of the utility model is to provide a battery pack processing and fixing device to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A battery pack processing and fixing device includes a base. A sinking cavity is recessed downward in the middle of the base. A plurality of guiding spheres are arranged on the sinking cavity. The guiding spheres are rotatably connected to the sinking cavity, and the top ends of the guiding spheres are higher than the upper end surface of the base. A clamping and fixing device is arranged outside the base.

[0007] By arranging guiding spheres on the base, when the battery pack is clamped, the battery pack moves horizontally on the base, that is, the battery pack realizes horizontal movement through the rolling of the guiding spheres, which can effectively avoid the horizontal friction between the battery pack and the base and reduce the damage of the battery pack caused by friction.

[0008] As a further scheme of the utility model: The clamping and fixing device includes a fixed limit seat fixedly connected to the base and a clamping limit seat arranged opposite to the fixed limit seat.

[0009] The battery pack is limited and clamped by the fixed limit seat and the clamping limit seat.

[0010] As a further solution of the present utility model: a limiting block is slidably connected to one side of the fixed limiting seat close to the sinking cavity.

[0011] A sliding limiting block is provided in the fixed limiting seat, and the sliding of the limiting block can be used to adapt to battery packs of different size specifications.

[0012] As a further solution of the present utility model: a sliding cavity is provided in the fixed limiting seat, the limiting block is slidably connected in the sliding cavity, and a spring is provided between the limiting block and the bottom of the sliding cavity.

[0013] By providing a sliding cavity in the fixed limiting seat and using a spring to realize the automatic reset of the limiting block in the sliding cavity.

[0014] As a further solution of the present utility model: the clamping limiting seat is slidably connected to the base, and a linear driving part for driving the clamping limiting seat to move towards or away from the fixed limiting seat is provided at the lower end of the base.

[0015] The position of the clamping limiting seat on the base can be controlled by the linear driving part, and then the clamping and fixing of the battery pack can be completed.

[0016] As a further solution of the present utility model: the linear driving part includes a telescopic cylinder fixedly connected to the lower end of the base, and the front end of the cylinder rod of the telescopic cylinder is fixedly connected to the clamping limiting seat.

[0017] The clamping limiting seat is driven to move horizontally by the telescopic cylinder and the cylinder rod, and then the battery pack can be clamped or released.

[0018] As a further solution of the present utility model: a notch parallel to the telescopic cylinder is provided on the base, the lower end of the clamping limiting seat is fixedly connected to the cylinder rod through a locking block, the locking block is slidably connected to the notch, and the clamping limiting seat is located above the base.

[0019] By providing a notch on the base, the notch penetrates the base up and down, and the horizontal length of the notch is smaller than the width of the base. Therefore, the locking block can slide in the notch, and then drive the clamping limiting seat to move from the outside of the base to the upper end of the base, so as to clamp and fix a battery pack with a smaller width.

[0020] As a further solution of the present utility model: a sliding limiting seat slidably connected to the base is provided on one side of the base, and the sliding direction of the sliding limiting seat is perpendicular to the connecting line direction of the clamping limiting seat and the fixed limiting seat.

[0021] A sliding limit seat is also provided, and the limiting direction of the sliding limit seat is perpendicular to the directions of the fixed limit seat and the clamping limit seat, so that the battery pack can be limited in two directions, namely horizontally and vertically.

[0022] As a further solution of the present utility model: a slide rail is provided at the lower end of the base, a slide bar is provided on the slide rail, the sliding limit seat is fixedly connected to the slide bar, and a locking bolt is provided on the slide bar.

[0023] The position of the sliding limit seat on the base can be adjusted through the slide bar and the slide rail to adapt to battery packs of different sizes and specifications.

[0024] Compared with the prior art, the beneficial effects of the present utility model are as follows: by setting the high point of the rotating sphere higher than the installation surface of the base, the bottom of the battery pack is supported by the rotating sphere, so that when there is relative movement on the battery pack base, through the rotating action of the rotating sphere, relative friction between the battery pack and the base can be avoided. At the same time, through the multiple springs arranged between the limiting block and the fixed limit seat, the extrusion force of the limiting block on the battery pack can be increased, as well as the applicability to battery packs of different models. It can effectively improve the problems that in the processing of existing new energy battery packs, the fixing device is prone to generate scratches on the surface layer of the battery pack, and the applicability of the existing fixing device is poor.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0034] Please refer to Figures 1-5 , in the embodiments of the present utility model, a battery pack processing and fixing device includes a base 100. A sunken cavity 101 is provided in the middle of the base 100 and recessed downward. A plurality of guiding spheres 103 are arranged on the sunken cavity 101. The guiding spheres 103 are rotatably connected to the sunken cavity 101, and the top ends of the guiding spheres 103 are higher than the upper end surface of the base 100. By providing the guiding spheres 103 on the base 100, when the battery pack is clamped, the battery pack moves horizontally on the base 100. That is, the battery pack realizes horizontal movement through the rolling of the guiding spheres 103, which can effectively avoid the horizontal friction between the battery pack and the base 100 and reduce the damage caused by friction to the battery pack.

[0035] A clamping and fixing device is provided on the outer side of the base 100. The clamping and fixing device includes a fixed limiting seat 110 fixedly connected to the base 100 and a clamping limiting seat 200 arranged opposite to the fixed limiting seat 110. The battery pack is limited and clamped by the fixed limiting seat 110 and the clamping limiting seat 200.

[0036] A limiting block 111 is slidably connected to the side of the fixed limiting seat 110 close to the sunken cavity 101. A sliding cavity is provided in the fixed limiting seat 110, and the limiting block 111 is slidably connected in the sliding cavity. A spring 112 is provided between the limiting block 111 and the bottom of the sliding cavity. A sliding limiting block 111 is provided in the fixed limiting seat 110, and the limiting block 111 can slide to adapt to battery packs of different size specifications. By providing a sliding cavity in the fixed limiting seat 110 and using a spring to realize the automatic reset of the limiting block in the sliding cavity

[0037] The clamping and limiting seat 200 is slidably connected to the base 100. A linear driving part for driving the clamping and limiting seat 200 to move towards or away from the fixed limiting seat 110 is provided at the lower end of the base 100. The linear driving part includes a telescopic cylinder 210 fixedly connected to the lower end of the base 100, and the front end of the cylinder rod 211 of the telescopic cylinder 210 is fixedly connected to the clamping and limiting seat 200. The position of the clamping and limiting seat 200 on the base 100 can be controlled by the linear driving part, thereby completing the clamping and fixing of the battery pack. The clamping and limiting seat 200 is driven to move horizontally by the telescopic cylinder 210 and the cylinder rod 211, so that the battery pack can be clamped or released. A notch 102 parallel to the telescopic cylinder 210 is provided on the base 100. The lower end of the clamping and limiting seat 200 is fixedly connected to the cylinder rod 211 through a locking block 212, and the locking block 212 is slidably connected to the notch 102. The clamping and limiting seat 200 is located above the base 100. By providing the notch 102 on the base 100, the notch 102 penetrates the base 100 vertically, and the horizontal length of the notch 102 is smaller than the width of the base 100. Therefore, the locking block 212 can slide in the notch 102, thereby driving the clamping and limiting seat 200 to move from the outside of the base 100 to the upper end of the base 100 to clamp and fix a battery pack with a smaller width.

[0038] A sliding limiting seat 120 slidably connected to the base 100 is provided on one side of the base 100.

The sliding limiting seat 120 is fixedly connected to the slide bar 140, and a locking bolt 141 is provided on the slide bar 140. A sliding limiting seat 120 is also provided. The limiting direction of the sliding limiting seat 120 is perpendicular to the directions of the fixed limiting seat 110 and the clamping and limiting seat 200. Therefore, the battery pack can be limited in two directions, namely horizontally and vertically. The position of the sliding limiting seat 120 on the base 100 can be adjusted through the slide bar 140 and the slide rail 130 to adapt to battery packs of different size specifications.

[0039] In this embodiment, by setting the high point of the rotating sphere higher than the mounting surface of the base 100, the bottom of the battery pack is supported by the rotating sphere. So that when there is relative movement on the base 100 of the battery pack, through the rotating action of the rotating sphere, relative friction between the battery pack and the base 100 can be avoided. At the same time, by providing a plurality of springs 112 between the limiting block 111 and the fixed limiting seat 110, the extrusion force of the limiting block 111 on the battery pack can be increased, as well as the applicability to battery packs of different models.

[0040] Therefore, it can effectively improve the problems that in the processing of existing new energy battery packs, their fixing devices are prone to generate scratches on the surface of the battery packs and the applicability of existing fixing devices is poor. Therefore, the utility model effectively overcomes some practical problems in the prior art and thus has high utilization value and practical significance.
