Description

Technical Field

[0001] This utility model relates to the field of automotive bracket technology, and in particular to a battery bracket. Background Technology

[0002] In the development of light commercial vehicles, lightweighting is a key direction. Lightweight design can effectively reduce vehicle energy consumption, increase driving range, and improve handling performance and transportation efficiency. As the power source for light commercial vehicles, the design of the battery mounting bracket is crucial for both vehicle lightweighting and stable battery installation.

[0003] Traditional battery bracket structures are often complex and use a lot of materials, resulting in a large weight, which contradicts the lightweight requirements of light commercial vehicles. Utility Model Content

[0004] The purpose of this utility model is to provide a battery holder that simplifies the structure of the battery holder and achieves lightweighting while ensuring structural strength through a reasonable structural design.

[0005] To achieve the above objectives, this utility model provides a battery bracket, including a top bracket and a bottom bracket arranged vertically, and a column detachably connecting the two. Both the top bracket and the bottom bracket have battery pack mounting holes, and the top bracket also has ear plate holes. Both the top bracket and the bottom bracket include two longitudinal supports arranged horizontally opposite each other and extending forward and backward, and multiple transverse supports connecting the two longitudinal supports. The longitudinal supports and transverse supports are perpendicular to each other. The longitudinal supports, transverse supports and the column are all angle steel structures, and the openings of the two longitudinal supports are arranged in opposite directions, forming a battery mounting space.

[0006] With the above structure, the upper and lower layers make reasonable use of space, providing sufficient installation height and space for the battery. Simultaneously, the columns ensure a stable connection between the top and bottom brackets, guaranteeing the stability of the battery installation. The crisscrossing structural design ensures that the top and bottom brackets have sufficient strength and stability to withstand the weight of the battery and various external forces during vehicle operation. Using angle steel as the main material effectively reduces the weight of the bracket while maintaining its strength, meeting the lightweight requirements of light commercial vehicles, and contributing to reduced energy consumption and increased driving range.

[0007] Preferably, a through groove is formed on the horizontal surface of the longitudinal support corresponding to the transverse support. The transverse support is inserted into the through groove, and when the transverse support is inserted into the through groove, the top surface of the transverse support is flush with the upper support surface of the longitudinal support. The through groove limits the position of the transverse support, ensuring welding accuracy. When the transverse support is inserted into the through groove, the top surface of the transverse support is flush with the upper support surface of the longitudinal support, ensuring the flatness of the bracket surface and facilitating the stable installation of the battery pack.

[0008] Preferably, reference holes are provided at both ends of the cross brace; positioning holes are provided on the horizontal surface of the longitudinal brace corresponding to the reference holes. By inserting positioning pins into the positioning holes and reference holes, temporary positioning of the longitudinal and cross braces is achieved, ensuring welding accuracy and avoiding the problem that the longitudinal and cross braces are prone to deformation due to welding or stress concentration caused by the through-groove cutting, resulting in a small stress area.

[0009] Preferably, the vertical surfaces of the cross braces of the top bracket are provided with downward-extending triangular legs at both ends; the vertical surfaces of the cross braces and the two side legs form a portal frame structure; the uprights are fixedly installed on the legs, and the ear plate holes are also made on the legs. This structure helps to distribute stress, further improving the strength and stability of the top bracket; moreover, it increases the area at both ends of the cross braces, which can increase the strength and stability of the top bracket, and also provides a suitable connection position for the installation of the uprights.

[0010] Preferably, the column also has through holes corresponding to the ear plate holes, and the column, support legs, and ear plates are fixedly connected as a whole by bolts. This facilitates the connection of the column, support legs, and ear plates into a whole by bolts, and at the same time distributes the weight of the bottom bracket to the ear plates, preventing the weight from falling on the top bracket and causing the cross brace mounting holes to be stressed and deformed.

[0011] Preferably, an arc-shaped transition zone is formed between the vertical surfaces of the outrigger and the cross brace. This arc-shaped transition zone avoids stress concentration, reduces damage to the bracket caused by vibration and impact during vehicle operation, and improves the service life of the bracket.

[0012] After adopting the above technical solution, the beneficial effects of this utility model are:

[0013] This utility model provides a battery bracket that solves the problem of unreasonable battery bracket design in the prior art, which leads to bulkiness and fails to meet the requirements of lightweighting. This utility model uses angle steel structure as the main material, which effectively reduces the weight of the bracket while ensuring its strength, thus meeting the lightweighting requirements of light commercial vehicles, helping to reduce vehicle energy consumption and increase driving range.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] The orientations mentioned in this specification are based on the orientation of the battery holder of this utility model when it is working normally, and do not limit its orientation during storage and transportation. They only represent relative positional relationships and do not represent absolute positional relationships.

[0025] Example 1:

[0026] like Figure 1 As shown, a battery bracket includes a top bracket 1 and a bottom bracket 2 arranged vertically, and a column 3 detachably connecting the two. Both the top bracket 1 and the bottom bracket 2 have battery pack mounting holes for securely mounting a battery pack 4 onto the corresponding bracket. This layered design makes efficient use of space, providing sufficient mounting height and space for the battery, while the column 3 ensures a stable connection between the top bracket 1 and the bottom bracket 2.

[0027] like Figure 2 and Figure 3 As shown, the top bracket 1 is also provided with ear plate holes; the top bracket 1 is fixedly installed onto the ear plates 5 through the ear plate holes. The ear plates 5 have two rows, welded to the longitudinal beams on the left and right sides of the frame (not shown in the figure), and are provided with mounting holes 51; correspondingly, there are also two rows of ear plate holes, located on the left and right sides of the top bracket 1. The top bracket 1 is stably fixed to multiple ear plates 5 by bolts, thus achieving stable hoisting.

[0028] like Figure 4 , Figure 5As shown, the top bracket 1 includes two longitudinal supports 11 arranged opposite each other and extending forward and backward, and multiple transverse supports 12 connecting the two longitudinal supports 11. In this embodiment, three transverse supports 12 are evenly arranged along the extension direction of the longitudinal supports 11. In practical applications, two or four transverse supports 12 can be designed according to the length of the longitudinal supports 11, and this embodiment does not limit this. The openings of the two longitudinal supports 11 are arranged opposite each other, forming a battery mounting space; battery pack mounting holes are provided on the longitudinal supports 11. The longitudinal supports 11 and transverse supports 12 are perpendicular to each other and are welded together as a whole, forming a trapezoidal shape extending forward and backward. This crisscrossing structural design ensures that the top bracket 1 has sufficient strength and stability to withstand the weight of the battery and various external forces during vehicle operation.

[0029] To achieve a lightweight design, the longitudinal brace 11 and the transverse brace 12 are angle steel structures, with the openings of the two longitudinal braces 11 facing each other. In this embodiment, the longitudinal brace 11 uses an equilateral angle steel structure, preferably 25*25*3mm. In practical applications, other specifications of angle steel can be adjusted according to the required load-bearing capacity. The transverse brace 12 of the top bracket 1 is an unequal-sided angle steel structure, with its horizontal surface supported at the bottom of the horizontal surface of the longitudinal brace 11, and the two are welded together. Its vertical surface extends downward, and triangular support legs 121 extending downward are provided at both ends. Thus, the vertical surface of the transverse brace 12 of the top bracket 1 and the two side support legs 121 form a portal frame structure. The mounting holes for the transverse brace are provided on the support legs 121, so that the upper end of the column 3 is fixedly installed on the support legs 121. In addition, ear plate holes are also provided on the support legs 121, and the ear plates 5 are fixed on the support legs 121. By setting the support legs 121, the area at both ends of the cross brace 12 is increased, which enhances the strength and stability of the top bracket 1 and provides a suitable connection position for the installation of the column 3. A through hole 31 is also provided on the column 3 corresponding to the ear plate hole. In this embodiment, there are two through holes 31, one above the other, to ensure a stable force distribution. The through hole 31 is oblong, thus ensuring its installation position. The column 3, support legs 121, and ear plate 5 are fixedly connected as a whole by bolts. The bolt connection method is firm and reliable, easy to disassemble, and facilitates maintenance and replacement of parts of the battery bracket when needed. At the same time, the weight of the bottom bracket 2 is also distributed to the ear plate 5, preventing the weight from falling on the top bracket 1, which would cause concentrated stress on the cross brace mounting hole and lead to deformation.

[0030] The column 3 is also an angle steel structure, preferably an unequal-sided angle steel structure in this embodiment. Its upper end is detachably fixed to the vertical surface of the cross brace 12. The detachable method is as follows: the vertical surface of the cross brace 12 has a cross brace mounting hole, and the column 3 has an upper fixing hole corresponding to the cross brace mounting hole; the column 3 has a lower fixing hole corresponding to the lower cross brace mounting hole; the detachable fixing is achieved by tightening the cross brace mounting hole and the upper / lower fixing holes with bolts. To enhance its strength, the width of the position where the lower fixing hole is located at the bottom of the column 3 is greater than its upper width.

[0031] Using angle steel structure as the main material for longitudinal brace 11, transverse brace 12 and column 3, the weight of the support is effectively reduced while ensuring the strength of the support, which meets the lightweight requirements of light commercial vehicles, helps to reduce vehicle energy consumption and increase driving range.

[0032] An arc-shaped transition zone 122 is formed between the vertical surfaces of the outrigger 121 and the cross brace 12. The arc-shaped transition zone 122 can avoid stress concentration, reduce damage to the bracket caused by vibration and impact during vehicle operation, and improve the service life of the bracket.

[0033] like Figure 6 As shown, in this embodiment, a through groove 111 is provided on the horizontal surface of the longitudinal support 11 corresponding to the transverse support 12. The transverse support 12 is inserted into the through groove 111. After the transverse support 12 is inserted into the through groove 111, the top surface of the transverse support 12 is flush with the upper support surface of the longitudinal support 11. The through groove 111 limits the transverse support 12, thereby ensuring welding accuracy. When the transverse support 12 is inserted into the through groove 111, the top surface of the transverse support 12 is flush with the upper support surface of the longitudinal support 11, ensuring the flatness of the bracket surface, which is beneficial to the stable installation of the battery pack.

[0034] The bottom bracket 2 and the top bracket 1 have basically the same structure. The only difference is the length of the legs. Since the bottom bracket 2 does not need to be fixed to the ear plate 5, the length of the legs on the bottom bracket 2 is shorter than the length of the legs 121 on the top bracket 1 in this embodiment.

[0035] The vertical surface of the longitudinal brace 11 is also provided with a slot 113 for connecting the battery ground wire.

[0036] Example 2:

[0037] like Figure 7 and Figure 8As shown, this embodiment is basically the same as embodiment one, except that the welding positioning method of the longitudinal support 11 and the transverse support 12 is different. In embodiment one, the welding method is to position the longitudinal support 11 and the transverse support by opening a through groove 111. Because of the cutting of the through groove 111, the force-bearing area of ​​the longitudinal support 11 and the transverse support at this position is small, and they are prone to deformation due to welding or force concentration. Therefore, in this embodiment, reference holes are opened at the left and right ends of the transverse support 12 respectively; positioning holes 112 are opened on the horizontal surface of the longitudinal support 11 corresponding to the reference holes. By inserting positioning pins into the positioning holes 112 and the reference holes, the temporary positioning of the two is achieved to ensure welding accuracy.

[0038] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
