Description

Technical Field

[0001] This utility model relates to the field of fixing plate technology, and in particular to a low-cost fixing plate for connecting a battery pack and an accessory to be installed. Background Technology

[0002] In the assembly of battery packs and accessories, a fixing plate is typically used at the bottom of the battery pack to assist in the assembly. The main function of the fixing plate is to ensure the stability and safety of the assembly. Through the fixing plate, the battery pack can be firmly connected to the accessory, preventing displacement or detachment during movement or vibration, thus protecting the battery pack from damage and ensuring the normal operation of the accessory. In existing technology, for the design of the customer's accessory, the fixing plate uses a raised arc on its bottom surface for assembly and fixation. The machining path of the raised arc is relatively complex, requiring precise programming and toolpath planning, high machining accuracy, and strict control of cutting parameters and various errors during machining. Moreover, problems such as vibration and radial runout are prone to occur during machining, affecting machining quality and increasing machining costs. Furthermore, due to the machining limitations of these raised arcs, considering material machinability and machining efficiency, the fixing plate is often made of alloys such as SUS304 stainless steel, resulting in higher weight. Additionally, the cost of developing molds and fixing plate prototypes is high, and the development cycle is relatively long. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a fixing piece in which the arc for fixing the main unit is changed from a convex shape to a concave shape, thereby reducing manufacturing costs and shortening the overall manufacturing cycle of the battery pack.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A fixing plate includes a fixing plate body, the fixing plate body includes a fastening area and an assembly area, the fastening area is fastened to the bottom of the battery pack, the bottom of the battery pack is provided with a limiting structure, the assembly area is provided with a concave arc, and the part to be assembled is rotated and slid along the concave arc to be assembled into position at the limiting structure.

[0006] The fixing plate body is made of alloy material or plastic.

[0007] In a preferred embodiment, the fastening area is provided with a connection hole for fastening connection to the bottom of the battery pack.

[0008] In a preferred embodiment, the assembly area has recessed arcs on both the front and back sides, with the two ends of the recessed arcs located on the front and back sides of the assembly area.

[0009] In a preferred embodiment, the recessed arc on the front side of the assembly area is arranged clockwise, and the recessed arc on the back side of the assembly area is arranged counterclockwise. There are multiple recessed arcs with different diameters. The recessed arcs are distributed at different heights to form an arc-shaped step structure. One end of each recessed arc on the same surface of the assembly area is located on the same edge of the assembly area, and the orthographic projections of the ends of every two recessed arcs located on the same side edge of the assembly area coincide.

[0010] In a preferred embodiment, the edge of the assembly area away from the fastening area is an arc, and after the fixing plate body is assembled on opposite sides of the bottom of the battery pack, the assembly areas of the two fixing plate bodies are opposite each other.

[0011] This invention changes the original convex arc of the fixing plate to the part to be assembled from a protruding one to a concave one. The part to be assembled can be fixed by rotating and sliding along the concave arc without changing the original assembly structure. The operation is simple. The fixing plate adopts a concave arc design, which reduces the processing difficulty and shortens the processing cycle compared with the convex arc design. It can also be made of plastic, reducing weight. The cost of fixing plate prototype and mold opening is also greatly reduced. Furthermore, the fixing plate assembly area adopts a double-sided concave arc design, which increases the applicability of assembly. The fixing plates on opposite sides of the bottom of the battery pack can be used interchangeably without identification.

[0019] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "front," "back," "left," "right," "front," "rear," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] See Figure 1 and Figure 2 In one embodiment, the fixing piece includes a fixing piece body, which includes a fastening area 1 and an assembly area 2. The fastening area 1 is fastened to the bottom of the battery pack, and the bottom of the battery pack is provided with a limiting structure 3. The assembly area 2 is provided with a concave arc 21, and the part to be assembled rotates and slides along the concave arc 21 to the limiting structure 3 for assembly.

[0023] This fixing piece, without altering the customer's assembly, changes the original convex arc used to fix the fixing piece to the part to be assembled from a protruding one to a concave one. The part to be assembled can be fixed by rotating and sliding along the concave arc 21. The operation is simple. Unlike the processing limitations of a protruding arc, the processing path of a concave arc is more direct, reducing the difficulty of tool path planning caused by complex shapes. The processing of the concave arc allows the tool to more easily approach and leave the fixing piece body during processing. In other words, due to the design of the concave arc, it is easier to control in processing compared to a protruding arc, reducing manufacturing costs. Since the relative positional relationship between the processing tool and the fixing piece body is more stable in the concave arc, it is beneficial to control the processing accuracy and reduces the interference between the tool and the fixing piece body. Thus, various types of tools can be selected to adapt to different processing requirements and material properties. Therefore, using a concave arc makes it possible to change the material of the fixing piece body to a lighter material, thereby reducing weight, further reducing manufacturing costs, shortening the production cycle, and significantly reducing the corresponding prototype and mold costs. Therefore, the fixing piece body can be made of alloy materials or lighter plastics.

[0024] In this specific implementation of Embodiment 1, the fastening area 1 is provided with a connection hole 11, which is used for fastening connection with the bottom of the battery pack. It should be noted that the fastening area 1 can also be provided with other existing fastening structures for fastening connection with the bottom of the battery pack.

[0025] See Figures 2 to 5 In another embodiment, both sides of the assembly area 2 are provided with recessed arcs 21. The two ends of the recessed arcs 21 are located on the front and back sides of the assembly area 21. In this embodiment, the fixing piece is changed from having arcs on one side to having arcs on both sides, so that it can be used on both sides, increasing adaptability. The two ends of the recessed arcs 21 are located on the front and back sides of the assembly area 2, that is, the starting and ending points of the recessed arcs 21 are at the edge of the assembly area 2, which facilitates the processing of the recessed arcs.

[0026] The recessed arc 21 on the front of assembly area 2 is set clockwise, and the recessed arc 21 on the back of assembly area 2 is set counterclockwise. The recessed arc 21 on the front and back of assembly area 2 rotate in opposite directions, so that the fixing piece can be assembled without identification when it is fastened to the opposite side of the bottom of the battery pack, and can be shared.

[0027] There are multiple concave arcs 21, with different diameters and distributed at different heights to form an arc-shaped stepped structure. The design of different diameters ensures that these concave arcs 21 fit tightly during fixation, avoiding gaps and further improving the stability of fixation. The concave arcs 21 distributed at different heights form multiple superimposed arc-shaped stepped structures, which can significantly increase the load-bearing capacity of the structure, enabling it to withstand greater rotational forces. It also increases the contact area with the components to be assembled, improving friction and contributing to the stable fixation of the components during rotation. After assembly, it can more effectively disperse the stress generated during rotation, reducing the force on individual concave arcs 21, thereby improving the overall stability.

[0028] Each recessed arc 21 on the same surface of assembly area 2 has one end set on the same side edge of assembly area 2, and the orthographic projections of the ends of every two recessed arcs 21 on the same side edge of assembly area 2 coincide. This facilitates the initial processing of the recessed arcs 21, reduces manufacturing difficulty, and this design also helps to simplify the assembly process and improve assembly efficiency.

[0029] The edge of assembly area 2 away from fastening area 1 is an arc. When the fixing plate body is assembled on opposite sides of the bottom of the battery pack, the assembly areas 2 of the two fixing plate bodies are opposite each other. After the fixing plate is fastened to the bottom of the battery pack, a limiting area is formed between the two assembly areas 2. The arc-shaped edge of assembly area 2 can further limit the center of the assembled host.

[0030] 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.
