Description

Technical Field

[0001] This utility model relates to the technical field of electric vehicle battery protection, and in particular to a battery protection device for an electric tricycle. Background Technology

[0002] Electric tricycles are powered by their battery packs, which are typically located in a battery compartment beneath the seat. To provide sufficient power, the battery pack usually consists of multiple batteries arranged side-by-side in the battery compartment, often connected in series to achieve the required voltage and capacity. When assembling the battery, multiple batteries are placed in a specific order and connected in series using appropriate methods to complete the overall assembly of the battery pack.

[0003] However, after multiple batteries are assembled and placed in the battery frame, gaps exist between the batteries and the frame, as well as between the batteries themselves. These gaps make the batteries susceptible to collisions and displacement during use. Displacement between batteries can damage the battery casing, causing dents or scratches. Furthermore, displacement can lead to battery connection failures, affecting the overall performance of the battery pack and posing certain safety hazards. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to propose a battery protection device for electric tricycles, which can limit the battery, prevent battery displacement and collisions between batteries, thereby ensuring battery performance and protection effect.

[0006] To achieve the above objectives, this utility model proposes a battery protection device for an electric tricycle, comprising a battery frame, two limiting plates, two limiting members, two first adjusting members, and two second adjusting members.

One end of each of the two first adjusting members is rotatably connected to the battery frame, and the other end of each of the two first adjusting members is rotatably connected to the corresponding limiting plate. One end of each of the two second adjusting members is rotatably connected to the battery frame, and the other end of each of the two second adjusting members is rotatably connected to the corresponding abutment plate.

Detailed Implementation

[0019] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0020] The battery protection device for an electric tricycle according to an embodiment of the present invention will now be described with reference to the accompanying drawings.

[0021] like Figures 1-4 As shown, the battery protection device for the electric tricycle in this embodiment of the present invention may include a battery frame 1, two limiting plates 2, two limiting members 3, two first adjusting members 4, and two second adjusting members 5.

[0022] Among them, the two limiting plates 2 are respectively slidably set in the battery frame 1;

[0023] In this embodiment of the application, two limiting plates 2 are used to limit and clamp the long side of multiple batteries (i.e. battery packs) placed side by side, thereby ensuring the limiting effect of the limiting plates 2.

[0024] Two limiting members 3 are slidably disposed in the battery frame 1 and are located between two limiting plates 2 respectively. The limiting member 3 may include an abutment plate 30 and an elastic telescopic member 31. A groove 300 is provided on the abutment plate 30. The elastic telescopic member 31 is slidably connected to the abutment plate 30 and is located in the groove 300.

[0025] In this embodiment of the application, two limiting members 3 are used to limit and clamp the wide side of the battery pack, thereby ensuring the limiting effect of the limiting members 3.

[0026] It is understandable that by setting the elastic telescopic member 31, the elastic telescopic member 31 can extend and retract within the abutment plate 30 and can move between the two limiting plates 2. Thus, after the limiting plate 2 limits and clamps the long side of the battery pack, the elastic telescopic rod retracts and can move to the wide side of the battery pack, and limits and clamps the wide side of the battery pack.

[0027] It is understandable that the groove 300 is recessed on the abutment plate 30, and the depth of the groove 300 is equal to the thickness of the elastic telescopic member 31, thereby ensuring that the abutment plate 30 and the elastic telescopic member 31 abut and limit the wide side of the battery.

[0028] Two first adjusting members 4 and two second adjusting members 5 are slidably disposed in the battery frame 1. One end of each of the two first adjusting members 4 is rotatably connected to the battery frame 1, and the other end of each of the two first adjusting members 4 is rotatably connected to the corresponding limiting plate 2. One end of each of the two second adjusting members 5 is rotatably connected to the battery frame 1, and the other end of each of the two second adjusting members 5 is rotatably connected to the corresponding abutment plate 30.

[0029] In this embodiment, the two first adjusting members 4 are used to adjust the moving distance of the corresponding limiting plate 2 within the battery frame 1, thereby limiting and clamping the long side of the battery pack.

[0030] In this embodiment, the two second adjusting members 5 are used to adjust the moving distance of the corresponding limiting plate 2 within the battery frame 1, thereby limiting and clamping the long side of the battery pack.

[0031] Specifically, in actual operation, relevant personnel place multiple batteries into the battery frame 1 in sequence and connect them in series to form a battery pack. After the series connection is completed, the relevant personnel operate the two first adjusting members 4 in sequence, so that the first adjusting members 4 drive the limiting plate 2 to move towards the long side of the battery pack and limit and clamp the long side of the battery pack. When the limiting plate 2 clamps the long side of the battery pack, the elastic shrinking member on the abutment plate 30 retracts. The relevant personnel then operate the two second adjusting members 5 in sequence, so that the two second adjusting members 5 drive the corresponding abutment plate 30 and elastic shrinking member to move towards the wide side of the battery pack and limit and clamp the wide side of the battery pack, thereby ensuring the battery's performance and protection effect.

[0032] In one embodiment of this utility model, such as Figure 2 As shown, the elastic telescopic member 31 may include a first telescopic plate 310, a second telescopic plate 311, a slide bar 312, and a spring 313.

[0033] The first telescopic plate 310 and the second telescopic plate 311 are slidably connected to the abutment plate 30 and are respectively located in the slide groove 300. The slide rod 312 is set on the abutment plate 30. One end of the slide rod 312 is slidably inserted into the first telescopic plate 310, and the other end of the slide rod 312 is slidably inserted into the second telescopic plate 311. The spring 313 is sleeved on the slide rod 312. One end of the spring 313 is connected to the first telescopic plate 310, and the other end of the spring 313 is connected to the second telescopic plate 311.

[0034] It is understandable that by setting the spring 313, the first telescopic plate 310 and the second telescopic plate 311 can automatically return to their initial state after retraction, and the first telescopic plate 310 and the second telescopic plate 311 can automatically adjust according to the length of the wide side of the battery pack, thereby improving the limiting effect of the device.

[0035] In one embodiment of this utility model, such as Figure 1 and Figure 3 As shown, the first adjusting member 4 may include a first cylinder seat 40, a first threaded rod 41, a first connecting cylinder 42, a first connecting rod 43, and a second connecting rod 44.

[0036] The first cylindrical base 40 is slidably disposed on the battery frame 1, the first threaded rod 41 is threadedly connected to the first cylindrical base 40, the first connecting cylinder 42 is slidably sleeved on the first threaded rod 41, one end of the first connecting rod 43 is rotatably connected to the battery frame 1, the other end of the first connecting rod 43 is rotatably connected to the first connecting cylinder 42, one end of the second connecting rod 44 is connected to the first connecting cylinder 42, and the other end of the second connecting rod 44 is rotatably connected to the limiting plate 2.

[0037] It should be noted that the first connecting cylinder 42 described in this embodiment abuts against the tightening cap (not shown in the figure) provided on the top of the first threaded rod 41, so that when the first threaded rod 41 rotates downward, it can drive the first connecting cylinder 42 to move downward, thereby pushing the limiting plate 2 to move within the battery frame 1.

[0038] In one embodiment of this utility model, such as Figure 1 and Figure 4 As shown, the second adjusting member 5 may include a second cylinder seat 50, a second threaded rod 51, a second connecting cylinder 52, a third connecting rod 53, and a fourth connecting rod 54.

[0039] The second cylindrical base 50 is slidably mounted on the battery frame 1, the second threaded rod 51 is threadedly connected to the second cylindrical base 50, the second connecting cylinder 52 is slidably mounted on the second threaded rod 51, one end of the third connecting rod 53 is rotatably connected to the battery frame 1, the other end of the third connecting rod 53 is rotatably connected to the second connecting cylinder 52, one end of the fourth connecting rod 54 is rotatably connected to the second connecting cylinder 52, and the other end of the fourth connecting rod 54 is rotatably connected to the abutment plate 30.

[0040] It should be noted that the second connecting cylinder 52 described in this embodiment abuts against the tightening cap (not shown in the figure) provided on the top of the second threaded rod 51, so that when the second threaded rod 51 rotates downward, it can drive the second connecting cylinder 52 to move downward, thereby pushing the abutment plate 30 to move within the battery frame 1.

[0041] Specifically, in the actual operation, the relevant staff put multiple batteries into the battery frame 1 in sequence and connect them in series to form a battery pack.

[0042] After the series connection is completed, the relevant personnel operate the two first adjusting parts 4 in sequence to rotate the first threaded rod 41. The first threaded rod 41 rotates inside the first cylinder seat 40 and rotates towards the inner bottom of the first cylinder seat 40. When the first threaded rod 41 rotates downward, it can drive the first connecting cylinder 42 to move downward. The first connecting cylinder 42 drives the first connecting rod 43 and the second connecting rod 44 to gradually move from the inclined state to the horizontal state, thereby pushing the limiting plate 2 to move towards the long side of the battery pack. This achieves the two limiting plates 2 to limit and clamp the long side of the battery pack. When the limiting plates 2 clamp the long side of the battery pack, the elastic contraction member on the abutment plate 30 contracts.

[0043] The relevant personnel then operate the two second adjusting parts 5 in sequence, thereby rotating the second threaded rod 51. The second threaded rod 51 rotates inside the second cylinder seat 50 and rotates towards the inner bottom of the second cylinder seat 50. When the second threaded rod 51 rotates downward, it can drive the second connecting cylinder 52 to move downward. The second connecting cylinder 52 drives the third connecting rod 53 and the fourth connecting rod 54 to gradually move from the inclined state to the horizontal state, thereby pushing the abutment plate 30, the first telescopic plate 310 and the second telescopic plate 311 to move towards the wide side of the battery pack. This enables the two limiting parts 3 to limit and clamp the wide side of the battery pack, ensuring the battery's performance and protection effect.

[0044] In summary, the battery protection device for the electric tricycle of this utility model embodiment can limit the battery, prevent battery displacement and collisions between batteries, thereby ensuring battery performance and protection effect.
