[0031] Reference below Figure 1-Figure 4 The installation component 100 of the coil spring according to the embodiment of the utility model is described. By setting the second installation surface 121 of the installation support 1 to be lower than the first installation surface 112, the battery pack can be avoided above the second installation surface 121, and a draft bevel 13 is formed between the two, which facilitates the molding of the installation support 1, reduces the risk of cracking of the installation component 100, and improves the quality of the installation component 100.

[0032] like Figure 1-Figure 4 As shown, a spiral spring installation assembly 100 according to an embodiment of the utility model includes: a mounting support 1.

[0033] The mounting bracket 1 is suitable for being connected to the vehicle frame, wherein the mounting bracket 1 can be connected to both the vehicle longitudinal beam and the vehicle cross beam, and the connection is made by welding. The connection of the mounting bracket 1 is stable and reliable. The mounting bracket 1 is formed with a first mounting surface 112 and a second mounting surface 121. The first mounting surface 112 is used for mounting a shock absorber, and the second mounting surface 121 is used for mounting a coil spring. That is, the installation of the shock absorber and the coil spring can be realized through the mounting bracket 1, and the reliable connection between the shock absorber and the coil spring and the vehicle frame can be ensured.

[0034] Among them, the coil spring is used to absorb vibration and impact, as well as to support and balance the load. The force absorbed by the coil spring is transmitted to the frame to achieve buffering and transmission of impact force. The shock absorber can control the vibration frequency of the coil spring to prevent the vehicle from bouncing excessively on uneven roads. Therefore, when the vehicle is driving, the coil spring provides static support and the shock absorber controls dynamic movement. The two work together to enable the vehicle to maintain balance during driving, thereby improving the vehicle driving experience.

[0035] The second mounting surface 121 is configured to be lower than the first mounting surface 112 to form an escape space above the second mounting surface 121 .

[0036] Specifically, the mounting support 1 in this embodiment is the upper support of the coil spring, that is, the coil spring is installed on the lower side of the second mounting surface 121 to achieve the connection and fixation of the coil spring, and the shock absorber is detachably connected to the first mounting surface 112, wherein the first mounting surface 112 and the second mounting surface 121 are spaced apart in the horizontal direction, and the second mounting surface 121 is lower than the first mounting surface 112, and the two form an avoidance space in the vertical space, and the avoidance space is used to avoid the battery pack or other structures located there.

[0037] Among them, the mounting bracket 1 is formed by stamping, and a draft bevel 13 is formed between the first mounting surface 112 and the second mounting surface 121. The draft bevel 13 is also called the demolding slope or demolding angle. Setting the draft bevel 13 can reduce the friction between the mounting bracket 1 in the mold and the mold surface, which helps to demold more smoothly and makes the molding of the mounting bracket 1 easier.

[0038] Therefore, when the battery pack or other structures occupy the installation space above the coil spring, the set avoidance space can avoid the battery pack or other structures and will not interfere with the arrangement of other structures such as the battery pack. In addition, a draft bevel 13 is set between the first mounting surface 112 and the second mounting surface 121, which can make the molding of the mounting bracket 1 simpler and reduce the risk of cracking during the molding process, thereby improving the production efficiency and production quality of the mounting bracket 1.

[0039] According to the installation component 100 of the coil spring according to the embodiment of the utility model, the second installation surface 121 of the installation support 1 is set lower than the first installation surface 112 to avoid the battery pack or other structures, and a draft bevel 13 is formed between the two, which facilitates the molding of the installation support 1 and reduces the risk of cracking between the first installation surface 112 and the second installation surface 121, thereby meeting the design requirements of the installation component 100.

[0040] In some embodiments, the mounting support 1 includes a first sub-board 11 and a second sub-board 12 that are bent and connected to each other. The first sub-board 11 is formed with an upwardly protruding mounting boss 111, and the top surface of the mounting boss 111 is formed with a first mounting surface 112. The second mounting surface 121 is formed on the second sub-board 12, and the side of the mounting boss 111 facing the second sub-board 12 is constructed as a draft bevel 13.

[0041] Specifically, the mounting support 1 includes a first sub-plate 11 and a second sub-plate 12, which are connected by bending, wherein a transition arc is formed at the connection between the first sub-plate 11 and the second sub-plate 12 to ensure smooth connection between the two, and the transition arc has a certain reinforcing effect to improve the connection strength between the two. The first sub-plate 11 is formed with a mounting boss 111, which protrudes upward relative to the second sub-plate 12, and a first mounting surface 112 is formed on the top surface of the mounting boss 111 for mounting the shock absorber, and a second mounting surface 121 is formed on the bottom surface of the second sub-plate 12 to fix one end of the coil spring, and the other end of the coil spring can be connected to the protruding structure on the rear axle or other structures, and the side of the mounting boss 111 facing the second sub-plate 12 is a draft bevel 13, and the mounting support 1 can be demolded along the draft bevel 13 during the molding process to improve the demolding efficiency.

[0042] The installation boss 111 can enhance the structural strength between the first sub-plate 11 and the second sub-plate 12, thereby enhancing the installation strength of the coil spring and the shock absorber. During vehicle operation, the stability of the shock absorber and the coil spring can be ensured, thereby improving the dynamic performance of the vehicle's shock absorption system.

[0043] In some embodiments, the first mounting surface 112 is configured as an inclined plane, which is inclined downward in a direction away from the second mounting surface 121 .

[0044] Specifically, Figure 1 and Figure 4 As shown, the mounting boss 111 is constructed as an inclined boss, which is inclined downward in a direction away from the second sub-plate 12, and the first mounting surface 112 is distributed along the top surface of the mounting boss 111, that is, the first mounting surface 112 is an inclined plane, and is inclined downward in a direction away from the second mounting surface 121, so that the inclined installation of the shock absorber can be achieved. In this way, during vehicle operation, the shock absorber can provide better wheel positioning control, which helps to maintain good contact between the wheel and the road surface when the vehicle turns, and improves the vehicle's handling and stability.

[0045] In some embodiments, the height difference between the highest position of the first mounting surface 112 and the second mounting surface 121 is L1, which satisfies: 33mm≤L1≤35mm.

[0046] Specifically, Figure 4As shown, the first mounting surface 112 has its highest point on the side close to the second mounting surface 121 and its lowest point on the side away from the second mounting surface 121. There is a height difference between the highest point of the first mounting surface 112 and the second mounting surface 121. The height difference can be set as L1, and the height difference can take values ​​such as 33mm, 34mm, 35mm, etc. By setting the above-mentioned values, a vertical space of at least 35mm can be formed above the second mounting surface 121. The height of the vertical space is relatively large, which is used to avoid the battery pack and realize the installation of the battery pack, and the coil spring can be installed on the second mounting surface 121.

[0047] The height difference between the highest point of the first mounting surface 112 and the second mounting surface 121 is not limited to that described in this embodiment, and can be set according to actual needs as long as it can provide installation space for the battery pack.

[0048] In some embodiments, Figure 4 As shown, the draft angle of the draft slope 13 relative to the second mounting surface 121 is A, and satisfies: A≥30°.

[0049] Specifically, the second mounting surface 121 is a horizontal surface, and the draft bevel 13 is inclined relative to the second mounting surface 121 and is inclined upward at a certain angle. This angle is the draft angle A, and the draft angle can be 30°, 35°, etc. By setting the above two values, the draft bevel 13 can be inclined upward at a draft angle of at least 30° relative to the second mounting surface 121. In this way, there is a certain demolding slope between the first mounting surface 112 and the second mounting surface 121. During the molding process, the mounting support 1 is demolded along the demolding slope of 30°, and the demolding process is easier and more convenient, thereby improving the production efficiency of the mounting support 1 and reducing the manufacturing cost.

[0050] The value of the draft angle is not limited to that described in this embodiment, and can be selected according to the actual height difference between the first mounting surface 112 and the second mounting surface 121 and the molding method.

[0051] In some embodiments, the draft slope 13 is configured as an arcuate surface, and the arcuate surface is arched and convex toward the second mounting surface 121. Specifically, as shown in FIG. Figure 3As shown, a portion of the first sub-plate 11 is formed with a mounting boss 111, and a draft bevel 13 is formed between the top surface of the mounting boss 111 and the second mounting surface 121, so that the draft bevel 13 is distributed around the mounting boss 111, and the draft bevel 13 is an arc-shaped surface, and the arc-shaped surface arches toward one side of the second mounting surface 121, and is smoothly connected to the mounting boss 111 at both ends of the arc-shaped surface, and the upper and lower ends of the arc-shaped surface are respectively formed with the first mounting surface 112 and the second mounting surface 121. The transition fillet 14 has a larger fillet, so that the overall structure is connected smoothly, which is more conducive to the molding of the mounting support 1, and can solve the cracking problem at the draft bevel 13, and the molding thinning amount meets the design requirements, thereby improving the product quality.

[0052] In some embodiments, the area of ​​the first mounting surface 112 is smaller than the area of ​​the second mounting surface 121. Specifically, the shape of the area of ​​the first mounting surface 112 is different from the shape of the second mounting surface 121. The shape of the first mounting surface 112 is rectangular, and the shape of the second mounting surface 121 is circular. The area of ​​the first mounting surface 112 is smaller, and the area of ​​the second mounting surface 121 is larger. More space can be reserved above the second mounting surface 121 to avoid the battery pack. In this embodiment, due to the large height difference between the first mounting surface 112 and the second mounting surface 121, a draft chamfer 13 with a certain angle needs to be set. The first mounting surface 112 can be reduced and partially made to an extreme position. For example, the first mounting surface 112 is only 5 mm larger than the mounting surface of the shock absorber, which increases the space required for the structural design. Sufficient installation space can be reserved to install the battery pack, and the setting requirements of the draft chamfer 13 can be met. The structural arrangement is reasonable, which can meet the installation of the shock absorber, the coil spring and the battery pack, and can also facilitate the molding of the mounting support 1.

[0053] In some embodiments, the spiral spring mounting assembly 100 further includes a reinforcing plate 2 , which is connected to the upper side of the mounting support 1 and is designed to conform to the shape of the mounting support 1 .

[0054] Specifically, the reinforcing plate 2 is used to strengthen the structural strength of the mounting support 1. Figure 1 As shown, the reinforcing plate 2 is located on the upper side of the mounting support 1, and the two can be connected by welding, thereby improving the connection strength between the two and enhancing the reinforcing effect of the reinforcing plate 2 on the mounting support 1. The reinforcing plate 2 can be designed along with the mounting support 1, and the overall structure of the reinforcing plate 2 is slightly larger than the overall structure of the mounting support 1, and the reinforcing plate 2 is fitted and connected to the mounting support 1 at least at two positions, the first mounting surface 112 and the second mounting surface 121, which can respectively enhance the structural strength of the first mounting surface 112 and the second mounting surface 121 of the mounting support 1 to improve the impact resistance of the two mounting surfaces.

[0055] Among them, connecting flanges are formed on the peripheries of the reinforcing plate 2 and the mounting support 1, and the reinforcing plate 2 and the mounting support 1 are respectively welded to the vehicle body longitudinal beam or other structural parts through the connecting flanges, thereby realizing the installation of the reinforcing plate 2 and the mounting support 1. In this way, when the vehicle is running, when the coil spring mounting assembly 100 is subjected to a large vibration, the force can be transmitted to the vehicle body longitudinal beam or other structural parts, the force is dispersed, the deformation of the coil spring mounting assembly 100 is reduced, and the service life is increased.

[0056] In some embodiments, Figure 1 As shown, the reinforcing plate 2 and the first mounting surface 112 are both provided with a first connecting hole 113 and an avoidance hole 114. The first connecting hole 113 is used to pass a connecting piece connected to the shock absorber, and the avoidance hole 114 is used to avoid the top of the shock absorber.

[0057] Specifically, the first mounting surface 112 is provided with a first connecting hole 113 and an avoidance hole 114, and correspondingly, the reinforcing plate 2 is provided with a first connecting hole 113 and an avoidance hole 114, there are two first connecting holes 113, the two first connecting holes 113 are spaced apart and the avoidance hole 114 is located between the two connecting holes, wherein the avoidance hole 114 can be constructed as a square hole for avoiding the shock absorber, the two connecting holes can be constructed as round holes, and connecting nuts are provided at the two connecting holes above the reinforcing plate 2, and the shock absorber is provided with two mounting holes, the connecting piece can be a connecting bolt, during installation, the top end of the shock absorber is passed through the avoidance hole 114, and the two connecting bolts are respectively passed through the two mounting holes, the two first connecting holes 113 and the connecting nuts from bottom to top, to realize the installation of the shock absorber, and the connection method is simple and convenient for disassembly and assembly.

[0058] and / or, if Figure 1-Figure 3 As shown, a plurality of second connection holes 122 are provided at the second mounting surface 121, and a plurality of plug welding holes 21 are provided at the reinforcing plate 2. The plurality of plug welding holes 21 correspond one to one with the plurality of second connection holes 122, and the reinforcing plate 2 is suitable for being welded to the mounting support 1 at the plug welding holes 21 and the second connection holes 122.

[0059] Specifically, the second connection holes 122 are used to discharge gas or leak liquid, and the plurality of second connection holes 122 are spaced apart and distributed, and the plurality of plug welding holes 21 are spaced apart and distributed, and the plurality of plug welding holes 21 are distributed one by one with the plurality of second connection holes 122, wherein the second connection holes 122 can be configured as round holes, square holes, etc., and the plug welding holes 21 can be configured as round holes, strip holes, etc., such as Figure 2As shown, the second connection hole 122 is constructed as a circular hole, and the plug welding hole 21 is constructed as a strip hole. The aperture of the strip hole is larger than the aperture of the circular hole, and the second connection hole 122 is located in the middle position of the plug welding hole 21. There are three second connection holes 122 and three plug welding holes 21. In this way, when the reinforcing plate 2 is connected to the mounting support 1, welding is performed at the three groups of plug welding holes 21 and the second connection holes 122 to achieve the connection and fixation of the two. The circumferential circle of the plug welding holes 21 is welded to the second mounting surface 121 of the mounting support 1 to improve the connection strength between the two. The welding point avoids the second connection hole 122, which does not affect the gas discharge and liquid leakage function of the second connection hole 122.

[0060] The number of the second connection holes 122 and the plug welding holes 21 can also be four, five, etc.

[0061] The utility model also provides a vehicle.
