This solution has low practicability for the battery protection board.

[0006] To achieve the above object, the utility model provides the following technical solution: A housing structure of a battery protection board includes a protection housing. The sides of the protection housing are axially symmetrically provided with chutes, and slidable sliders are arranged inside the chutes. One end inside the chutes is provided with a buffer structure.

[0014] In the technical solution disclosed by the present utility model, during the compression of the spring, the impact force on the housing can be buffered and energy-absorbed, avoiding serious damage to the protection housing caused by direct rigid force contact, reducing the loss of the protection housing, so as to achieve the function of protecting both the battery and preventing damage to the protection housing.

[0015] Through the buffer structure provided by the present utility model, when the protection housing hits an object, it will move itself, driving the sliders fixed on both sides to move inside the sliding groove.

[0022] The following will cooperate with the drawings and embodiments to detail the implementation manners of the present application, so as to fully understand the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects and implement accordingly.

[0023] Figures 1-4 This is an embodiment of the present utility model, a housing structure of a battery protection board, including a protective shell 1. Slide grooves 2 are symmetrically arranged on the sides of the protective shell 1, and a slidable slide block 3 is arranged inside the slide grooves 2. A buffer structure 4 is arranged at one end inside the slide grooves 2. Heat dissipation openings are arranged in a rectangular array on the bottom surface of the protective shell 1, and a heat dissipation structure 5 is arranged inside the heat dissipation openings.

[0024] The specific problem targeted by this specific embodiment is as follows: When the battery protection board at the bottom of the vehicle is impacted by road stones or other objects, although the safety of the battery is protected, the battery protection board itself will be severely damaged, and it is impossible to balance the protection of the battery and the anti-damage of the protection board. The practicality of this solution for the battery protection board is not high. The present utility model uses the compression of the spring 45 to buffer and absorb the impact force of the protective shell 1, avoiding direct rigid force contact from causing severe damage to the protective shell 1 and reducing the loss of the protective shell 1, so as to achieve the effect of both protecting the battery and preventing damage to the protective shell 1.

[0025] The buffer structure 4 includes a left side plate 41 disposed inside the sliding groove 2, and outer arc plates 42 are symmetrically arranged on the side surface of the left side plate 41. A slidable inner arc plate 43 is disposed inside the outer arc plates 42, and a right side plate 44 is fixed to the side surface of the inner arc plate 43. The right side plate 44 is fixed to the left side plate 41 through a spring 45. In this specific embodiment, a moving block is provided on the side surface of the inner arc plate 43, and a sliding opening matching the moving block is formed on the side surface of the outer arc plate 42. The moving block is slidably connected to the inside of the sliding opening. When the protective housing 1 hits an object, it will move itself, driving the sliders 3 fixed on both sides to move inside the sliding groove 2. The sliding groove 2 is fixedly connected to the chassis of the vehicle. When the slider 3 moves inside the sliding groove 2, it will squeeze the right side plate 44. When the right side plate 44 moves, it will squeeze the spring 45, so that the spring 45 absorbs energy by deforming during the impact, absorbing the rigid force hitting the protective housing 1, thereby achieving the effect of protecting the battery through the protective housing 1 while also absorbing energy to protect the protective housing 1 and preventing it from being severely damaged.

[0026] In this specific embodiment, the heat dissipation structure 5 includes a heat-conducting copper plate 51 fixedly connected to the inside of the heat dissipation port, and a heat dissipation grille 52 is disposed on the bottom surface of the heat-conducting copper plate 51. A heat dissipation silica gel pad 53 is disposed on the bottom surface of the heat dissipation grille 52, and a negative pressure fan 54 is fixed to the bottom surface of the heat dissipation silica gel pad 53. A plurality of insertion holes are formed on the side surface of the heat dissipation grille 52, and copper tubes 9 for increasing the heat dissipation area and the strength of the heat dissipation grille 52 are disposed inside the insertion holes;

[0027] Through the setting of the heat dissipation structure 5, the high temperature generated by the battery working inside the protective housing 1 will be transferred to the heat-conducting copper plate 51, and further transferred to the heat dissipation grille 52. The relatively large-area heat dissipation grille 52 can quickly dissipate the heat. At the same time, the heat that is not dissipated in time will be transferred to the heat dissipation silica gel pad 53 for dissipation again, and the negative pressure fan 54 works to quickly exchange the surrounding hot air to maintain its heat dissipation capacity. This solution can dissipate heat while maintaining the airtightness of the protective housing 1, preventing dust and liquid from entering the battery internal to cause short-circuit damage.

[0028] The control mode of the present utility model is automatically controlled by a controller. The control circuit of the controller can be realized by simple programming by those skilled in the art. The power supply also belongs to the common knowledge in this field. And the present utility model is mainly used to protect mechanical devices, so the control mode and circuit connection of the present utility model will not be further explained in detail.

[0029] It should be noted that in this text, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not explicitly listed, or further includes elements inherent in such a process, method, article or device.

[0030] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model, and the scope of the present utility model is defined by the appended claims and their equivalents.
