Technical Field

[0001] This utility model belongs to the field of power supply housing technology, and in particular relates to a protective housing for battery power supplies that is easy to install. Background Technology

[0002] A battery is a device used to store electrical energy. Its working principle is generally based on electrochemical reactions. It converts electrical energy into chemical energy through spontaneous oxidation and reduction reactions inside the battery, thereby achieving the storage of electrical energy. Nowadays, lithium batteries have emerged, which have advantages such as high energy density, light weight, and long life compared to traditional lead-acid batteries.

[0003] During battery use, manufacturers often install them in a casing to protect them from direct damage and potential dangers such as combustion. However, poor heat dissipation of the casing can affect the battery's heat dissipation. To solve this problem, there is an urgent need for a protective casing for battery power supplies that is easy to install. Utility Model Content

[0004] The purpose of this utility model is to address the problem that manufacturers often install batteries in casings during use to protect them from direct damage and potential fire hazards, but poor heat dissipation of the casings can negatively impact battery cooling. Therefore, this utility model proposes a protective casing for battery power supplies that is easy to install.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a protective housing for a battery power supply that is easy to install, comprising a housing, heat dissipation holes on the surface of the housing, a fixing component inside the housing, and a sealing component at the top of the housing; the fixing component includes a heat dissipation plate, a slider fixedly connected to one side of the heat dissipation plate, a spring fixedly connected to a groove on one side of the slider, an mounting sleeve slidably connected to the outer wall of the slider, and a damping rod inside the spring.

[0006] As a further description of the above technical solution:

[0007] The other end of the spring is fixedly connected to the mounting sleeve, and one side of the mounting sleeve is fixedly connected to the housing.

[0008] As a further description of the above technical solution:

[0009] One end of the damping rod is fixedly connected to the mounting sleeve, and the other end of the damping rod is fixedly connected to the slider.

[0010] As a further description of the above technical solution:

[0011] The heat sink consists of four pieces arranged in a rectangular shape, with each pair of heat sinks having a chamfered edge at the point where they touch.

[0012] As a further description of the above technical solution:

[0013] The sealing assembly includes a sealing plate, which is slidably connected to the housing via a groove formed on its bottom surface.

[0014] As a further description of the above technical solution:

[0015] The sealing plate is slidably connected to a fixing plate through a groove opened therein, and a lever plate is fixedly connected to the top surface of the fixing plate.

[0016] As a further description of the above technical solution:

[0017] A threaded ring is fixedly connected to the top surface of the sealing plate, and a limit plate is slidably connected to the outer wall of the threaded ring. One end of the fixed plate is slidably connected to the limit plate through a groove opened in the housing.

[0018] As a further description of the above technical solution:

[0019] The threaded ring is internally threaded with a knob, and the dial plate is slidably connected to it through a groove on the top surface of the sealing plate.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0021] 1. In this utility model, a heat dissipation plate is provided inside. During battery use, the battery is placed in the placement groove formed by the heat dissipation plate, so that the heat dissipation plate is in close contact with the battery surface. During use, the heat dissipation plate dissipates heat. When the electric bicycle is in motion, the battery will be subjected to bumps and shakes. Springs and damping rods cushion the impact. During the shaking, the heat dissipation plate moves, compressing the air between the heat dissipation plate and the shell. Through this design, the uneven surface of the heat dissipation plate increases the heat dissipation area, thereby improving the battery's heat dissipation efficiency. At the same time, when the electric bicycle shakes during operation, the springs and damping rods reduce the impact of the shaking. The movement of the heat dissipation plate also accelerates the airflow between the heat dissipation plate and the shell, thereby improving the heat dissipation efficiency.

[0022] 2. In this utility model, by providing a fixing plate inside, after the battery is placed in the housing, the sealing plate is placed on the top of the housing, and at the same time, the push plate is pushed to insert the fixing plate into the groove opened in the housing. Then, the limiting plate is placed in the groove formed by the push plate to limit the push plate. Through this design, it is realized that in use, only the push plate needs to be pushed to insert the fixing plate into the groove opened in the housing and the limiting plate is used to limit the push plate, so that the sealing plate and the housing can be fixed together. Compared with the traditional method of fixing with multiple screws, a lot of time can be saved, thereby improving installation efficiency. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-4This utility model provides a technical solution: a protective housing for a battery power supply that is easy to install, including a housing 1, a heat dissipation hole 2 on the surface of the housing 1, a fixing component 4 inside the housing 1, and a sealing component 3 at the top of the housing 1; the fixing component 4 includes a heat dissipation plate 41, a slider 42 fixedly connected to one side of the heat dissipation plate 41, a spring 43 fixedly connected to a groove on one side of the slider 42, an mounting sleeve 45 slidably connected to the outer wall of the slider 42, and a damping rod 44 inside the spring 43.

[0031] The other end of the spring 43 is fixedly connected to the mounting sleeve 45. One side of the mounting sleeve 45 is fixedly connected to the housing 1. One end of the damping rod 44 is fixedly connected to the mounting sleeve 45. The other end of the damping rod 44 is fixedly connected to the slider 42. There are four heat sinks 41 in total, which are connected end to end in a rectangular shape. The heat sinks 41 have chamfers at the contact points between each pair of heat sinks 41.

[0032] The specific implementation method is as follows: During the use of the battery, the battery is placed in the placement groove formed by the heat sink 41, and the heat sink 41 is in close contact with the surface of the battery. During the use, since the heat sink 41 itself is made of metal, it has a good thermal conductivity and its surface is provided with ribs, which increases its surface area and thus improves the heat dissipation effect. During the electric bicycle ride, the battery will be bumped and shaken, which will put a certain amount of pressure on the slider 42 and buffer it through the spring 43 and the damping rod 44. During the shaking, the heat sink 41 moves, which will compress the air between the heat sink 41 and the shell 1, thereby making the air flow and improving the heat dissipation efficiency.

[0033] The sealing assembly 3 includes a sealing plate 34, which is slidably connected to the housing 1 through a groove on its bottom surface. A fixing plate 36 is slidably connected to the sealing plate 34 through a groove inside it. A lever 35 is fixedly connected to the top surface of the fixing plate 36. A threaded ring 33 is fixedly connected to the top surface of the sealing plate 34. A limit plate 32 is slidably connected to the outer wall of the threaded ring 33. One end of the fixing plate 36 is slidably connected to the housing 1 through a groove. A knob 31 is threadedly connected to the threaded ring 33. The lever 35 is slidably connected to the sealing plate 34 through a groove on its top surface.

[0034] The specific implementation method is as follows: After the battery is placed in the housing 1, the sealing plate 34 is placed on the top of the housing 1, and the push plate 35 is pushed to move the fixing plate 36, so that the fixing plate 36 is inserted into the groove opened in the housing 1. Then, the limiting plate 32 is placed in the groove formed by the push plate 35 to limit the push plate 35. At the same time, the knob 31 is rotated to fix it with the threaded ring 33, thereby preventing the limiting plate 32 from sliding upward.

[0035] Working principle: During battery use, the battery is placed in the slot formed by the heat dissipation plate 41, ensuring that the heat dissipation plate 41 is in close contact with the battery surface. Then, the sealing plate 34 is placed on the top of the housing 1. Simultaneously, the pusher plate 35 is pushed to move the fixing plate 36, causing the fixing plate 36 to insert into the slot opened in the housing 1. Then, the limiting plate 32 is placed in the slot formed by the pusher plate 35 to limit the pusher plate 35. At the same time, the knob 31 is rotated to fix it with the threaded ring 33, thereby preventing the limiting plate 32 from sliding upward. During use, since the heat dissipation plate 41 is made of metal, it has good thermal conductivity, and its surface has ribs, which increases its surface area, thereby improving the heat dissipation effect. During the electric bicycle's operation, the battery will be subjected to bumps and some shaking, which will exert a certain amount of pressure on the slider 42. This is buffered by the spring 43 and the damping rod 44. During the shaking, the heat dissipation plate 41 moves, which will compress the air between the heat dissipation plate 41 and the housing 1, thereby causing air flow and improving the heat dissipation efficiency.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
