Description

Technical Field

[0001] This utility model relates to the field of new energy batteries, and in particular to a box mounting bracket. Background Technology

[0002] In the new energy vehicle industry, after the new energy battery is manufactured, the battery box needs to be fixed to the vehicle frame. Usually, it needs to be fixed by a mounting bracket. In the mounting bracket, a sleeve is usually used to connect with the mounting hole on the vehicle frame, and bolts are used to pass through the sleeve and the mounting hole to fix it.

[0003] In the existing technology, the mounting bracket usually uses a sleeve fixing bracket welded to a support plate to form support for the sleeve. However, deformation is prone to occur when the sleeve fixing bracket and the support plate are welded, which affects the flatness of the mounting surface of the sleeve and leads to unstable installation when the sleeve is installed with the vehicle frame.

[0004] The mounting brackets in the existing technology have low assembly accuracy because they are manufactured and welded separately from the sleeve fixing bracket and the support plate. Utility Model Content

[0005] This utility model provides a box mounting bracket that solves the problem of low assembly accuracy in the prior art. The technical solution is as follows:

[0006] A battery enclosure mounting bracket includes a battery enclosure, an upper support plate, a partition, and a sleeve.

[0007] The upper support plate includes a second support plate and two first support plates. The two first support plates are arranged in parallel and spaced apart. The second support plate is disposed between the two first support plates and is perpendicular to the first support plates. The second support plate has mounting holes that match the outer diameter of the sleeve. The first and second support plates are formed by bending. The first support plate is perpendicularly connected to the battery box.

[0008] The partition is disposed at the bottom of the second support plate and parallel to the second support plate. The sleeve passes through the mounting hole and is disposed on the partition. The partition has bolt holes that match the inner diameter of the sleeve.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0024] Figure 1 This is a schematic diagram of the bracket and battery box assembly provided in this embodiment of the utility model; Figure 2 This is a schematic diagram of the overall structure of the bracket provided in this embodiment of the utility model; Figure 3 This is a schematic diagram of the overall structure of the bracket after removing the sleeve, as provided in an embodiment of this utility model. Figures 1 to 3 The illustrated enclosure mounting bracket includes a battery enclosure 1, an upper support plate 2, a partition plate 3, and a sleeve 4. The upper support plate 2 includes a second support plate 22 and two first support plates 21, which are arranged in parallel and spaced apart. The second support plate 22 is disposed between the two first support plates 21 and is perpendicular to the first support plates 21. The second support plate 22 has mounting holes 221 that match the outer diameter of the sleeve 4. The first support plates 21 and the second support plate 22 are formed by bending. The first support plate 21 is perpendicularly connected to the battery enclosure 1. The partition plate 3 is disposed at the bottom of the second support plate 22 and is parallel to the second support plate 22. The sleeve 4 passes through the mounting holes 221 and is disposed on the partition plate 3. The partition plate 3 has bolt holes 31 that match the inner diameter of the sleeve 4.

[0025] For example, in this embodiment of the present invention, the support plate 2 is made of a steel plate. The steel plate is pre-cut according to the shape and size of the first support plate 21 and the second support plate 22, and mounting holes 221 are opened. Then, the steel plate is bent using a bending forming process to form the structure of the first support plate 21 and the second support plate 22. The ends of the two first support plates 21 are respectively attached to and welded to the battery box 1. Then, the partition plate 3 is inserted between the two first support plates 21, and one end is welded to the battery box, and both sides are welded to the two first support plates 21. Then, the sleeve 4 is passed through the mounting hole 221 and placed on the partition plate 3, so that the inner diameter of the sleeve 4 is aligned with the bolt hole 31. Then, the top of the sleeve 4 is welded to the mounting hole 221, thereby completing the fixed installation of the entire bracket. Compared to traditional techniques that use a sleeve fixing bracket welded to a support plate to support the sleeve, this embodiment uses an integrally formed first support plate 21 and second support plate 22 to provide support for the sleeve 4, thereby reducing the welding process during assembly and ensuring the flatness of the sleeve 4 and the positional accuracy of the mounting bolts.

[0026] The present invention provides a box mounting bracket, which consists of a first support plate 21 and a second support plate 22 forming an upper support plate 2. The first support plate 21 and the second support plate 22 are formed by bending, so that when the sleeve 4 is installed on the upper support plate 2, the flatness of the mounting surface of the sleeve 4 will not be affected by the deformation caused by welding. The sleeve 4 is installed through the mounting hole 221, and the bottom support of the sleeve 4 is provided by the partition plate 3, so that the inner diameter of the sleeve 4 is aligned with the bolt hole 31. The sleeve 4 is installed and fixed to the frame by bolts passing through the inner diameter and bolt hole 31. This invention can effectively solve the problem of low assembly accuracy in the prior art.

[0027] Optionally, the upper support also includes a first ear 23, of which there are two, and are perpendicular to both the first support plate 21 and the second support plate 22. The two first ears 23 are respectively located on the outer side of the two first support plates 21.

[0028] For example, in this embodiment of the present invention, the first ear 23 can also be manufactured together with the first support plate 21 and the second support plate 22 using an integral molding process. When manufacturing the upper support plate 2, a reserved area for the first ear 23 is pre-cut on the steel plate. Then, the steel plate is bent to form the structure of the first support plate 21, the second support plate 22 and the first ear 23. By setting the first ear 23, the welding area between the first support plate 21 and the battery box 1 can be increased, so that the bracket can be more stably fixed on the battery box, thereby improving the stability of the bracket.

[0029] Optionally, the first ear 23 is connected to the battery box 1 by resistance welding.

[0030] For example, in this embodiment of the present invention, resistance welding has the characteristics of high welding efficiency and low cost. When resistance welding is used, there is no need to fill other materials, which makes the deformation of the weldment small, can realize automated welding, and the equipment cost of resistance welding is low, which can reduce the production cost of this bracket.

[0031] Optionally, a first hydrophobic hole 32 is provided on the side of the partition 3 near the battery box 1.

[0032] For example, in this embodiment of the present invention, by providing a first drainage hole 32 on the partition 3, on the one hand, water can be drained through the first drainage hole 32 when it splashes onto the support structure, preventing corrosion of the support structure due to excessive water accumulation. The first drainage hole 32 also improves the service life of the support. On the other hand, providing a first drainage hole 32 on the partition 3 reduces the weight of the partition 3, allowing it to be more securely connected to the battery box 1. This provides a more stable bottom support for the sleeve 4, further improving the stability of the support.

[0033] Optionally, it also includes a lower support plate 5, which is located below the upper support plate 2 and between the two first support plates 21. One end of the lower support plate 2 is provided with a second lug 51, which is angled to the lower support plate 5 and is fitted and connected to the battery box 1.

[0034] For example, in this embodiment of the present invention, a single steel plate can be bent and formed between the lower support plate 5 and the second lug 51. The lower support plate 5 is placed between the two first support plates 21 and welded thereto. The second lug 51 is then fitted and welded to the battery box 1. By setting the lower support plate 5, the connection strength between the two first support plates 21 can be improved. By setting the second lug 51, the connection strength between the bracket and the battery box 1 can be improved, thereby further enhancing the stability of the bracket.

[0035] Optionally, the second ear 51 and the separator 3 are both connected to the battery box 1 by laser welding.

[0036] For example, in this embodiment of the present invention, although resistance welding has the characteristics of high welding efficiency and low cost, it requires a certain amount of equipment placement space during welding. The battery box 1 usually has height requirements and cannot provide too much space in the vertical direction for welding. Laser welding can solve the problem of insufficient space. Laser welding equipment is more expensive, but it has the characteristics of high efficiency and precision, and does not require too much space to install equipment. It can meet the requirement of welding and fixing the second lug 51 and the partition 3 to the battery box 1 in the longitudinal direction of the battery box 1.

[0037] Optionally, the lower support plate 5 is provided with a second drainage hole 52 that matches the first drainage hole 32.

[0038] For example, in this utility model embodiment, by providing a second drainage hole 52, water can be easily discharged from the partition 3 and then continue to flow out through the second drainage hole 52 on the lower support plate 5, preventing water from accumulating between the lower support plate 5 and the battery box 1 and corroding the bracket. By providing the second drainage hole 52, the service life of the bracket is further improved.

[0039] Optionally, the lower support plate 5 and the second lug 51 are set at an obtuse angle, the second drainage hole 52 is elongated, and one end of the second drainage hole 52 extends to the battery box 1.

[0040] For example, in this embodiment of the present invention, by setting the second hydrophobic hole 52 as an elongated strip, the water dripping from the first hydrophobic hole 32 can flow out more smoothly from the second hydrophobic hole 52. Extending one end of the second hydrophobic hole 52 to the battery box 1 can prevent water from accumulating in the dead corner between the lower support plate 5 and the battery box 1 and being unable to drain, thereby further improving the service life of the bracket.
