Description

Technical Field

[0001] This utility model relates to the field of automotive battery technology, and in particular to a high-efficiency installable automotive battery kit. Background Technology

[0002] Currently, new energy vehicles and electric equipment place higher demands on the ease of rapid replacement and maintenance of battery kits. However, existing mainstream automotive battery kits have significant shortcomings in their structural design. Their housings are mostly closed or semi-closed rigid cuboid structures with large tolerances in the fit between the internal space and the battery itself, and lack effective guiding and buffering mechanisms. This results in large-area, high-resistance direct sliding friction between the battery casing and the inner wall of the housing during installation and disassembly. Operators often need to expend considerable physical effort and use tools to complete the disassembly and assembly, severely limiting replacement efficiency. Furthermore, this long-term hard friction and impact continuously damages the battery's outer protective layer, affecting not only its sealing and insulation performance but also potentially causing serious safety hazards such as structural deformation, internal short circuits, and even thermal runaway, significantly shortening the battery's lifespan and increasing the overall life-cycle maintenance costs. Utility Model Content

[0003] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a high-efficiency installable and removable vehicle battery kit to solve one or more problems in the prior art.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: A high-efficiency removable automotive battery kit, the battery kit comprising: The housing includes an enclosing bottom plate, side plates, top plate, and one end plate, and the housing contains a relatively movable battery body. The movable assembly, configured to enable movement of the battery body relative to the housing, includes rotatable rollers symmetrically arranged at one end of the battery body and a handle arranged at the other end face of the battery body. The limiting group is configured to protect the battery body during installation and removal from the housing, and includes a first limiting member symmetrically arranged on the inner surface of the side plate, a second limiting member arranged on the inner surface of the bottom plate and centered thereon, and a third limiting member arranged on the inner surface of the end plate.

[0005] Furthermore, positioning grooves are provided at both ends of the base plate, and the positioning grooves at each end are symmetrically arranged about the second limiting member.

[0006] Furthermore, the positioning grooves at both ends of the base plate are symmetrically arranged about the second limiting member.

[0007] Furthermore, the roller protrudes from the bottom of the battery body and also protrudes from the side end face of the battery body near the end plate. The roller can be fixed or detached relative to the positioning groove.

[0008] Furthermore, the battery kit also includes a support block, which is disposed on the end face of the battery body near the end plate and protrudes outwards at the same distance as the protrusion of the roller.

[0009] Furthermore, the first limiting member is evenly distributed along the side plate, and the side plate also has slots formed at both ends of the first limiting member.

[0010] Furthermore, the battery kit includes a locking assembly comprising a locking rod and a latch, the locking rod being rotatably engaged with the bottom of a base plate away from the end plate, and the latch being rotatably engaged with the locking rod.

[0011] Furthermore, a hook portion is provided on the top plate at one end near the latch, and the latch can be fixed or detached relative to the hook portion.

[0012] Furthermore, the battery body is provided with a power display and an output interface on the side of the end face away from the end plate.

[0013] Furthermore, the battery body is also provided with a handle on its top.

[0014] Compared with the prior art, the beneficial technical effects of this utility model are as follows: (i) By setting up the moving group, the sliding friction between the battery body and the box is transformed into rolling friction by using the cooperation between the rollers in the moving group and the positioning groove on the base plate, as well as the handle. This not only makes it easy and smooth to push and pull the battery body, but also completes the stable locking of the battery body after installation and the temporary positioning during disassembly by the engagement and disengagement of the rollers and the positioning groove, which significantly improves the installation and disassembly efficiency and operational safety.

[0015] (ii) Through the multi-directional design of the limiting group, the first limiting component is combined with the side plate with slots to effectively prevent the battery from having a hard collision with the side plate of the box during movement. At the same time, the setting of the second limiting component at the bottom of the box and the third limiting component at the end of the box effectively avoids the risk of wear and damage to the battery body caused by inertial impact during vehicle movement. Furthermore, in conjunction with the locking component, additional constraints are provided for the battery body during transportation and use to ensure the safety of the battery body.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description of a high-efficiency, removable automotive battery kit, in conjunction with the accompanying drawings and specific embodiments, is provided. The advantages and features of this utility model will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions, used only to facilitate and clearly illustrate the purpose of the embodiments of this utility model. Please refer to the accompanying drawings for a clearer understanding of the objectives, features, and advantages of this utility model. It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are only for illustrative purposes and to aid those skilled in the art; they are not intended to limit the implementation conditions of this utility model and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to the size, without affecting the effects and objectives achieved by this utility model, should still fall within the scope of the technical content disclosed in this utility model.

[0023] For ease of understanding and clear description, in this embodiment, the side of the end plate 14 is referred to as the right end of the housing 1 and the battery body 2.

[0024] Please see Figures 1 to 5The high-efficiency removable vehicle battery kit of this embodiment includes: The battery housing 1 houses a relatively movable battery body 2. In this embodiment, both the housing 1 and the battery body 2 are cuboid structures, and the battery kit is horizontally installed in the vehicle along the length of the housing 1 during use and installation. The housing 1 is fixedly installed in the vehicle in one piece, and the operator only needs to install and remove the battery body 2 inside the housing 1 for replacement. The housing 1 includes an enclosing bottom plate 11, side plates 12, top plate 13, and a right-side end plate 14, meaning that the left end of the housing 1 has an opening to facilitate the replacement of the battery body 2.

[0025] The movable assembly 3, configured to enable movement of the battery body 2 relative to the housing 1, includes rotatable rollers 31 symmetrically arranged at the right end of the battery body 2 and a handle 32 arranged at the left end of the battery body 2. In this embodiment, two rollers 31 are provided, with parts of each roller protruding from the bottom of the battery body 2 and also from the right end face of the battery body 2. By using the rollers 31, when installing or removing the battery body 2, the operator only needs to combine operation with a gentle push or pull of the handle 32, and the battery body 2 can move smoothly along the length of the housing 1 with the assistance of the rollers 31. This greatly reduces the friction between the bottom of the battery body 2 and the bottom of the housing 1, making the replacement of the battery body 2 easier and faster. At the same time, the design and use of the rollers 31 also effectively reduces the wear on the bottom of the battery body 2 caused by traditional long-term friction, improving the service life and safety of the battery body 2.

[0026] The limiting group 4 is configured to protect the battery body 2 during the installation and removal process relative to the housing 1, and includes a first limiting member 41 symmetrically arranged on the inner surface of the side plate 12, a second limiting member 42 arranged on the inner surface of the bottom plate 11 and centered thereon, and a third limiting member 43 arranged on the inner surface of the end plate 14.

[0027] Specifically, the first limiting members 41 are evenly distributed along the side plate 12. In this embodiment, the first limiting members 41 are vertically arranged on the side plate 12, and the side plate 12 also forms slots 121 at both ends of each of the first limiting members 41. During the movement of the battery body 2 relative to the housing 1, both sides of the battery body 2 move in contact with the first limiting members 41. Preferably, the first limiting members 41 are made of elastic material and are arc-shaped in this embodiment. When the battery body 2 shifts, they can play a buffering and protective role, avoiding hard collisions and reducing the risk of damage. In addition, the design of the first limiting members 41 allows the battery body 2 to form a gap after being positioned relative to the side plate 12, creating a ventilation space. Furthermore, the contact between the battery body 2 and the first limiting members 41 during movement is a line contact, which reduces friction during movement compared to traditional surface contact and improves installation and disassembly efficiency. Meanwhile, the slot 121 can reduce the weight of the side plate 12 to a certain extent. The material design of the side plate 12 can also make the side plate 12 form a certain elastic deformation block in each of the first limiting member 41 areas. When the battery body 2 is slightly offset during installation or disassembly, if the first limiting member 41 still cannot meet the offset after the maximum elastic deformation, it will transmit to the side plate 12 to generate a small amount of elastic deformation, further preventing the battery body 2 from hard collision.

[0028] Furthermore, the first limiting member 41 is also uniformly provided with second holes 411, and the surface of the side plate 12 is also provided with first holes 122. The first holes 122 and the second holes 411 are concentrically arranged to form a through connection. Through the synergistic effect of the first holes 122, the second holes 411 and the slot holes 121, the battery body 2 can achieve better air circulation when used in the housing 1, which helps the heat generated by the battery body 2 during operation to be dissipated in a timely manner, reduces the probability of the battery body 2 failing due to overheating, and improves the stability and reliability of the battery kit.

[0029] The second limiting member 42 is centered on the inner surface of the base plate 11. Preferably, the second limiting member 42 is made of elastic material. After the battery body 2 is installed in the housing 1, it plays a protective and limiting role, and can also prevent the battery body 2 from colliding with the bottom of the housing 1 due to inertia during vehicle bumpy driving, effectively ensuring the safety of the battery body 2. Positioning grooves 111 are provided at both the left and rear ends of the base plate 11, and the two positioning grooves 111 at each end are symmetrically arranged with respect to the second limiting member 42. The roller 31 can be fixed or detached relative to the positioning grooves 111.

[0030] Specifically, when the battery body 2 is pushed into the housing 1, and the roller 31 moves to the positioning groove 111 on the right end, the roller 31 accurately embeds into the positioning groove 111 on the right end under the weight of the battery body 2. At this time, the positioning groove 111 fixes the roller 31, and the bottom of the battery body 2 rests on the second limiting member 42, ensuring that the battery body 2 is stable in the housing 1 and will not move arbitrarily due to bumps during vehicle operation. At this time, the side of the battery body 2 is also in contact with the first limiting member 41, which also reduces the shaking of the battery body due to inertia during vehicle operation to a certain extent. When the battery body 2 needs to be disassembled, the operator applies force to the handle 32 on the left end of the battery body 2. Due to the circular structure of the roller 31, the roller 31 disengages from the positioning groove 111 under the force. Then, the battery body 2 can be easily pulled out of the housing 1 by the rolling of the roller 31. When the roller 31 moves to the positioning groove 111 on the left end of the base plate 11, the roller 31 will also embed into the positioning groove 111 on the left end under its own weight, which serves as a temporary positioning function to prevent the battery body 2 from accidentally sliding out of the housing 1 due to improper operation, causing safety hazards or damage. Preferably, the positioning groove 111 is a through hole structure in this embodiment. In other embodiments, it can also be designed as an arc-shaped groove to accommodate the roller 31. By reasonably setting the depth and curvature of the arc-shaped groove, it can better adapt to rollers 31 of different specifications, improving the versatility and flexibility of the battery kit.

[0031] Furthermore, when the battery body 2 is pushed into the housing 1, the third limiting member 43, located on the inner surface of the end plate 14, effectively prevents the battery body 2 from excessively moving forward and colliding with the end plate 14 due to inertia during vehicle operation, thus providing front-end protection and limiting for the battery body 2. Preferably, the third limiting member 43 is an elastic buffer block. When the battery body 2 contacts the third limiting member 43, the elastic buffer block can absorb part of the impact force through its own elastic deformation, reducing the collision damage to the battery body 2 and improving the safety of the battery kit during vehicle operation.

[0032] Furthermore, the top of the battery body 2 is also provided with a handle 32. When the battery body 2 moves into the positioning groove 111 at the left end, the operator can more easily apply force through the handle 32 on the top to completely remove the battery body 2 from the box 1. Especially when the battery kit is installed in a high position in the vehicle, the handle 32 on the top makes the operation more convenient and safe, avoiding the situation where the battery body 2 may tilt or slip due to uneven force when operating from only one side of the handle 32.

[0033] Furthermore, the battery kit also includes a support block 5, which is disposed on the end face of the battery body 2 near the end plate 14, forming a protrusion on the right end of the battery body 2, and the protrusion distance is the same as that of the roller 31. Thus, when the battery body 2 is taken out from the housing 1, the combined action of the roller 31 and the support block 5 allows the battery body 2 to be placed stably on a horizontal surface, avoiding possible shaking or tipping due to the support of the roller 31 alone. This improves the stability of the battery body 2 in the non-installed state and also facilitates subsequent inspection, maintenance or replacement operations by the operator.

[0034] The battery kit includes a locking assembly 6, which comprises a locking rod 61 and a latch 62. The locking rod 61 is rotatably engaged with the bottom of the base plate 11, which is located away from the end plate 14, i.e., the left end of the base plate 11. The latch 62 is rotatably engaged with the locking rod 61. A hook portion 131 is provided on the top plate 13 near the latch 62, and the latch 62 can be fixed or released relative to the hook portion 131.

[0035] Specifically, after the battery body 2 is pushed into the housing 1 and the roller 31 is embedded in the positioning groove 111 on the right end, the operator can rotate the locking rod 61 to make the latch 62 rotate upward and hook onto the hook part 131. At this time, the locking assembly 6 is in a locked state, which can further prevent the battery body 2 from sliding out of the housing 1 due to bumps or other unexpected situations during vehicle operation, greatly improving the safety and stability of the battery kit during vehicle use. When it is necessary to disassemble the battery body 2, first rotate the locking rod 61 to release the latch 62 from the hook part 131, thus releasing the locking state. Then, the battery body 2 can be taken out of the housing 1 in the aforementioned manner using the handle 32 and the roller 31. Preferably, the contact surface between the locking rod 61 and the battery body 2 can be made of elastic material to achieve soft contact when the locking component 6 locks the battery body 2, avoiding hard damage to the battery body 2. At the same time, the use of elastic material can also enhance the stability of the locking to a certain extent and reduce the loosening of the locking caused by vehicle vibration.

[0036] The surface of the latch 62 that mates with the hook portion 131 may be provided with anti-slip texture or increased friction. The battery body 2 is further provided with a power indicator 21 and an output interface 22 on the left end face of the battery body 2, away from the end plate 14. The power indicator 21 can display the remaining power of the battery body 2 in real time, allowing operators to understand the battery's power status in a timely manner, so as to reasonably arrange the charging or battery replacement time and avoid affecting the normal use of the vehicle due to insufficient power. The output interface 22 is used to connect to the vehicle's electrical system to provide stable power support to the vehicle. Its interface type and specifications can be designed and matched according to the actual needs of the vehicle to ensure efficient and reliable power transmission.

[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
