[0037] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] One of the purposes of the utility model is to provide a novel battery compartment fixing plate to solve the problem that the existing battery compartment fixing plate has many installation and welding processes, thereby resulting in low production efficiency and poor product consistency.

[0039] Another object of the present invention is to provide a battery compartment support assembly having the above-mentioned battery compartment fixing plate.

[0040] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0041] Embodiment 1

[0042] like Figure 1-Figure 2As shown, this embodiment provides a battery compartment fixing plate 100, which is an integrated bent fixing plate with a concave middle and convex ends, and can be specifically formed by bending sheet metal. In the integrated bent fixing plate, the middle is concave to form a middle concave portion 101, and the two ends of the integrated bent fixing plate are convex relative to the middle concave portion 101, respectively serving as the first support end 103 and the second support end 104 of the battery compartment fixing plate 100. The first support end 103 and the second support end 104 are preferably flat support structures, and the entire battery compartment fixing plate 100 is "concave" as a whole. The first support end 103 and the second support end 104 of the integrated bent fixing plate are both provided with a mounting structure for fixing the battery compartment, and a slot hole 102 is provided in the middle concave portion 101 of the integrated bent fixing plate, and the slot hole 102 is used for welding with the bottom tube 300. The above scheme opens a slot 102 at the position of the battery compartment fixing plate 100 that is used to contact the bottom tube 300, that is, the middle recessed portion 101. When the battery compartment fixing plate 100 and the bottom tube 300 are welded, only one welding operation is performed in the slot 102 to achieve welding between the slot 102 and the bottom tube 300, thereby realizing welding of the battery compartment fixing plate 100 and the bottom tube 300, and no secondary welding is required at other positions of the middle recessed portion 101. Compared with the existing battery compartment fixing plate 200 that requires two welding operations at two edges, this embodiment has the advantage of simplifying the fixing plate installation process, and the product production efficiency and quality consistency are improved.

[0043] In this embodiment, the slot 102 may be a rectangular slot, a circular slot or a slot of any other shape. In this embodiment, the slot 102 is preferably a rectangular slot, and the length direction of the rectangular slot extends along the length direction of the battery compartment fixing plate 100. Compared with other shapes, the rectangular slot can make the welding area extend along the length direction of the battery compartment fixing plate 100, thereby increasing the welding length of the battery compartment fixing plate 100 and the bottom tube 300 in its length direction, which is beneficial to improving the connection strength between the battery compartment fixing plate 100 and the bottom tube 300.

[0044] In this embodiment, the mounting structure is preferably a mounting hole 105 opened on the first support end 103 and the second support end 104. Generally, in order to ensure the structural strength of the battery compartment fixing plate 100 itself, only one mounting hole 105 is opened at a position close to each end of the first support end 103 and the second support end 104. In actual application, multiple battery compartment fixing plates 100 can be used simultaneously to ensure the installation and support strength of the battery compartment.

[0045] In this embodiment, the mounting hole 105 is preferably a stretch hole formed on the battery compartment fixing plate 100, and an internal thread may be provided in the stretch hole. The stretch hole has a structural advantage of being less likely to slip.

[0046] like Figure 7As shown in the figure, although the middle part of the existing battery compartment fixing plate 200 is subjected to rib pressing to form a reinforcing rib 203, the overall structural strength of the fixing plate is insufficient and the strength still does not meet the standard requirements. Based on this, in this embodiment, at least one side edge of the back of the battery compartment fixing plate 100 is bent and flanged to form a fixing plate reinforcing flange structure 106. Figure 2 As shown, in order to save costs, this embodiment preferably only provides a fixing plate reinforcing flange structure 106 on one side edge of the back of the battery compartment fixing plate 100 , and the fixing plate reinforcing flange structure 106 is perpendicular to the battery compartment fixing plate 100 .

[0047] In this embodiment, the first supporting end 103 and the second supporting end 104 are preferably arranged flush with each other, that is, the surface of the first supporting end 103 and the surface of the second supporting end 104 are located at the same height to maintain the horizontal state of the battery compartment.

[0048] In summary, the battery compartment fixing sheet 100 proposed in this embodiment has the following beneficial effects:

[0049] (1) By opening a slot in the battery compartment fixing plate, the upper and lower diagonal welding of the existing fixing plate can be changed to welding at the slot, and the two-gun welding pass can be changed to a single-gun welding pass. This not only optimizes the welding form and simplifies the installation process of the fixing plate, but also improves the manufacturability of the battery compartment fixing plate, while improving production efficiency, reducing production costs, and improving product quality consistency.

[0050] (2) By bending and flanging the edge of the battery compartment fixing plate, the strength of the battery compartment fixing plate can be increased to a level greater than the standard requirement, making it less prone to deformation and improving the quality, thereby overcoming the defect of insufficient structural strength of the existing fixing plate.

[0051] (3) The mounting holes are drawn holes, which are not prone to slippage and have a long service life.

[0052] (4) Both ends of the same battery compartment fixing plate can be used to support and fix the battery compartment. Compared with the traditional four-piece split fixing plate, it achieves fewer parts and can further improve the production efficiency of the battery compartment fixing plate.

[0053] Embodiment 2

[0054] like Figure 3 and Figure 4 As shown, this embodiment proposes a battery compartment support assembly 400, including a bottom tube 300 and a battery compartment fixing plate 100 as disclosed in the first embodiment, the battery compartment fixing plate 100 is engaged with the bottom tube 300 through a middle recessed portion 101 thereof, and is welded to the bottom tube 300 at a slot 102.

[0055] In this embodiment, in order to ensure that the battery compartment fixing plate 100 effectively supports the battery compartment, it is preferred that the heights of the two ends of the battery compartment fixing plate 100, namely the first supporting end 103 and the second supporting end 104, are not lower than the surface height of the bottom tube 300. Generally, it is preferred that the surface heights of the first supporting end 103 and the second supporting end 104 are the same, and their surface heights are slightly higher than the surface height of the bottom tube 300.

[0056] In this embodiment, the width of the middle recessed portion 101 of the battery compartment fixing plate 100 is greater than the width of the bottom tube 300, and a gap for the wiring harness to pass through is reserved between at least one side of the bottom tube 300 in the width direction and the middle recessed portion 101. Generally, it is preferred that a gap for the wiring harness to pass through is reserved between both sides of the bottom tube 300 in the width direction and the middle recessed portion 101.

[0057] In the present embodiment, two groups of battery compartment fixing plates 100 are preferably spaced apart on the bottom tube 300 along its length direction, and the two groups of battery compartment fixing plates 100 are respectively a first battery compartment fixing plate 401 and a second battery compartment fixing plate 402, wherein a gap 1 403 is left between the first side of the middle recessed portion 101 of the first battery compartment fixing plate 401 and the first side in the width direction of the bottom tube 300, a gap 2 404 is left between the second side of the middle recessed portion 101 of the first battery compartment fixing plate 401 and the second side in the width direction of the bottom tube 300, and the width of the gap 2 404 is greater than the width of the gap 1 403; a gap 3 405 is left between the first side of the middle recessed portion 101 of the second battery compartment fixing plate 402 and the first side in the width direction of the bottom tube 300, a gap 406 is left between the second side of the middle recessed portion 101 of the second battery compartment fixing plate 405 and the second side in the width direction of the bottom tube 300, and the width of the gap 406 is greater than the width of the gap 3 405. Figure 3 and Figure 4 As shown, the interval one 403 and the interval three 405 are located at one side of the bottom tube 300 in the width direction, and the interval two 404 and the interval four 406 are located at the other side of the bottom tube 300 in the width direction.

[0058] Furthermore, the structures and sizes of the first battery compartment fixing plate 401 and the second battery compartment fixing plate 402 may be completely the same, or they may have different sizes according to different installation requirements of different battery compartments. Figure 3 and Figure 4As shown, the extension length of the end of the first battery compartment fixing piece 401 close to the interval 1 403 is longer than the extension length of the end of the second battery compartment fixing piece 402 close to the interval 3 405, and the extension length of the end of the first battery compartment fixing piece 401 close to the interval 2 404 is substantially equal to the extension length of the end of the second battery compartment fixing piece 402 close to the interval 4 406. Except for the different extension lengths of the ends of the fixing pieces, the structures, welding methods and use principles of the first battery compartment fixing piece 401 and the second battery compartment fixing piece 402 are the same, and will not be repeated here.

[0059] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
