Abstract
Description
Technical Field
[0001] This utility model relates to the field of vehicle body controllers, and more particularly to a vehicle body controller and a vehicle. Background Technology
[0002] In vehicle layout design, electronic control units (ECUs) installed in the passenger compartment, especially body control units, generally have no waterproofing requirements or low waterproofing requirements. However, in recent years, due to the increasing number of vehicle functions and ECUs, the layout space in the passenger compartment has become more compact, and the uncertainty of the ECU's location has increased. As a result, the BCM (Body Control Module) requires a higher waterproofing rating, and more and more vehicle manufacturers are now requiring the BCM to have a waterproofing rating of IPX2.
[0003] In existing technology, the body control unit is typically located under the seats and trunk lid. The lower housing of the body control unit is usually designed as a recessed structure, and the upper housing is assembled and fixed to the lower housing by inserting into the recessed structure, with the assembly gap exposed on the outside. When water is sprayed on the seats or trunk lid, the water can flow along the assembly gap into the recess, and then into the body control unit, causing the body control unit to malfunction and potentially ignite. For the body control unit, the waterproof sealing design usually involves filling the recess of the lower housing with sealant, and a seal is formed when the upper housing is inserted into the recess. However, the use of sealant significantly increases the cost of the vehicle.
[0004] Therefore, there is a need to provide a vehicle body controller that has good waterproof performance, while also saving production costs and increasing production capacity and profits. Utility Model Content
[0005] In view of the above problems, this utility model is proposed to provide a vehicle body controller and vehicle that overcomes or at least partially solves the above problems.

[0010] The upper shell and the lower shell are stacked together. The upper side plate has a first protrusion structure at the end near the lower bottom plate, and the lower side plate has a second protrusion structure at the end near the upper top plate.
[0011] Furthermore, along the direction from the lower shell to the upper shell, the first protruding structure and the second protruding structure are in close contact with each other, and along the direction from the center of the upper top plate to the edge of the upper top plate, the first protruding structure is located on the side of the second protruding structure that is away from the interior of the lower shell.
[0012] Optionally, the first protrusion structure has a plurality of first planes parallel to the lower base plate, a third plane between two adjacent first planes, and a first plane and a third plane forming a step; along the direction from the edge of the upper top plate to the center of the upper top plate, the distance between the plurality of first planes and the outer surface of the lower base plate gradually increases;
[0013] The second protrusion structure has multiple second planes parallel to the lower base plate, and a fourth plane between two adjacent second planes. A second plane and the fourth plane form a step. Along the direction from the edge of the upper top plate to the center of the upper top plate, the distance between the multiple second planes and the outer surface of the lower base plate gradually increases. The outer surface of the lower base plate is the surface of the lower base plate away from the upper top plate.
[0014] Optionally, the third plane is provided with a first groove, the fourth plane is provided with a first boss, the first boss is embedded in the first groove, and / or, the third plane is provided with a second boss, the fourth plane is provided with a second groove, the second boss is embedded in the second groove.
[0015] Optionally, when the third plane is provided with the first boss, the first boss is an elastic boss; when the fourth plane is provided with the second boss, the second boss is an elastic boss.

[0017] Optionally, along the direction from the center of the upper top plate to the edge of the upper top plate, the distance between the surface of the upper top plate facing away from the lower bottom plate and the outer surface of the lower bottom plate gradually decreases.
[0018] Optionally, the outer surface of the upper shell is provided with a first drainage groove, and the outer surface of the lower side plate is provided with a second drainage groove;

[0021] Optionally, the lower bottom plate has a fifth groove on the plane opposite to the upper top plate, the bottom of the fifth groove has a mounting hole, and the upper top plate has a mounting groove on the surface facing the lower bottom plate;
[0022] The fastener passes through the mounting hole and is embedded in the mounting groove. The fastener is fixedly connected to the mounting groove to fix the upper top plate and the lower bottom plate together.
[0023] Secondly, embodiments of this application provide a vehicle that includes the aforementioned body controller.
[0024] In this embodiment, the upper and lower shells are stacked, with a first protruding structure at the end of the upper side plate near the lower bottom plate and a second protruding structure at the end of the lower side plate near the upper top plate. The first and second protruding structures are fitted together along the direction from the lower shell to the upper shell. Because the first and second protruding structures are fitted together, a gap is formed at their joint. The first protruding structure includes a first plane and a third plane, and the second protruding structure includes a second plane and a fourth plane. The gap formed by fitting the second and fourth planes together is called an assembly gap. When water flows down the upper side plate and reaches the assembly gap between the upper and lower side plates, due to gravity, the water will continue to flow down the lower side plate and will not enter the assembly gap. This avoids water entering the body control unit, causing malfunction or fire, and also avoids the use of sealant, thus solving the problem of significantly increasing vehicle costs due to the use of sealant.
[0025] For the aforementioned waterproof body controller, by optimizing the mechanical structure of the body controller itself, the waterproof rating can reach IPX2 when the body controller is installed vertically. This gives the body controller excellent waterproof performance, makes the layout design of the body controller more flexible, improves the efficiency of the body controller, and at the same time reduces the number of automotive parts, lowers production costs, and increases production capacity and profits.

[0041] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0042] It should be noted that, in the embodiments of this application, the vehicle type in which the body controller is located includes, but is not limited to, fuel-powered vehicles, electric vehicles, hybrid vehicles, etc.
[0043] like Figure 1 and Figure 2As shown, the vehicle body controller in this application may specifically include: an upper shell 10 and a lower shell 20; the upper shell 10 includes an upper top plate 11 and an upper side plate 12, the upper side plate 12 is disposed around the edge of the upper top plate 11 and is connected to the upper top plate 11, and protrudes from one side of the upper top plate 11 along the thickness direction of the upper top plate 11; the lower shell 20 includes a lower bottom plate 21 and a lower side plate 22, the lower side plate 22 is disposed around the edge of the lower bottom plate 21 and is connected to the lower bottom plate 21, and protrudes from one side of the lower bottom plate 21 along the thickness direction of the lower bottom plate 21. In the direction, the lower side plate 22 protrudes from one side of the lower bottom plate 21; the upper shell 10 and the lower shell 20 are stacked, the upper side plate 12 near the lower bottom plate 21 is a first protruding structure 13, and the lower side plate 22 near the upper top plate 11 is a second protruding structure 23; and along the direction from the lower shell 20 to the upper shell 10, the first protruding structure 13 and the second protruding structure 23 are attached to each other, and along the direction from the center of the upper top plate 11 to the edge of the upper top plate 11, the first protruding structure 13 is located on the side of the second protruding structure 23 away from the interior of the lower shell 20.
[0044] In this embodiment, since the upper shell 10 and the lower shell 20 are stacked, a first protruding structure 13 is located at the end of the upper side plate 12 near the lower bottom plate 21, and a second protruding structure 23 is located at the end of the lower side plate 22 near the upper top plate 11. The first protruding structure 13 and the second protruding structure 23 are fitted together along the direction from the lower shell 20 to the upper shell 10. Because the first protruding structure 13 and the second protruding structure 23 are fitted together, a gap is formed at the joint. Figure 2 As shown, the first protruding structure 13 includes a first plane 131 and a third plane 132, and the second protruding structure 23 includes a second plane 231 and a fourth plane 232. The gap formed by fitting the second plane 132 and the fourth plane 232 together is called the assembly gap. When water flows down along the upper side panel 12 and reaches the assembly gap between the upper side panel 12 and the lower side panel 22, due to gravity, the water will continue to flow down along the lower side panel 22 and will not enter the assembly gap. This avoids water from entering the body control unit and causing the body control unit to malfunction or catch fire. It also avoids the use of sealant, thus solving the problem that using sealant would significantly increase vehicle costs.
[0045] In the embodiments of this application, such as Figure 2 As shown, the first protrusion structure 13 has multiple first planes 131 parallel to the lower base plate 21, and a third plane 132 between two adjacent first planes 131. A first plane 131 and a third plane 132 form a step. Along the direction from the edge of the upper top plate 11 to the center of the upper top plate 11, the distance between the multiple first planes 131 and the outer surface of the lower base plate 21 gradually increases.
[0046] The second protrusion structure 23 has multiple second planes 231 parallel to the lower base plate 21, and a fourth plane 232 between two adjacent second planes 231. A second plane 231 and a fourth plane 232 form a step. Along the direction from the edge of the upper top plate 11 to the center of the upper top plate 11, the distance between the multiple second planes 231 and the outer surface of the lower base plate 21 gradually increases. The outer surface of the lower base plate 21 is the surface of the lower base plate 21 that is away from the upper top plate 11.
[0047] In this embodiment, reference Figure 2 Since the first plane 131 is parallel to the lower base plate 21, and there is a third plane 132 between two adjacent first planes 131, forming a step between a first plane 131 and a third plane 132, it can be concluded that the first plane 131 is perpendicular to the third plane 132. Similarly, it can be concluded that the second plane 231 and the fourth plane 232 are perpendicular. At this time, when the first protrusion structure 13 and the second protrusion structure 23 abut against each other, the first plane 131 and the second plane 231 abut against each other, and the third plane 132 and the fourth plane 232 abut against each other. At this time, the third plane 132 and the fourth plane 232 fit together to form an assembly gap. When water flows through the assembly gap, it will be blocked, thereby preventing water from flowing into the interior of the body controller.
[0048] As the distance between the multiple first planes 131 and the surface of the lower bottom plate 21 away from the upper top plate 11 gradually increases along the direction from the edge of the upper top plate 11 to the center of the upper top plate 11, the distance between the multiple second planes 231 and the surface of the lower bottom plate 21 away from the upper top plate 11 also gradually increases along the direction from the edge of the upper top plate 11 to the center of the upper top plate 11. Thus, there are multiple first planes 131 and multiple second planes 231. Since there is a third plane 132 between two adjacent first planes 131 and a fourth plane 232 between two adjacent second planes 231, there are multiple third planes 132 and fourth planes 232, thus forming multiple assembly gaps. This can better prevent water from entering the body controller and thus protect the safety of the body controller.
[0049] In the embodiments of this application, such as Figure 4 As shown, the third plane 132 is provided with a first groove 15, the fourth plane 232 is provided with a first boss 25, the first boss 25 is embedded in the first groove 15, and / or, the third plane 132 is provided with a second boss 16, the fourth plane 232 is provided with a second groove 26, the second boss 16 is embedded in the second groove 26.
[0050] For example, in this embodiment, the third plane 132 has a first groove 15, and the fourth plane 232 has a first boss 25. The first boss 25 is embedded in the first groove 15. The first groove 15 can be an arc-shaped groove or a square groove. When the first groove 15 is an arc-shaped groove, the corresponding first boss 25 is an arc-shaped boss. The first groove 15 and the first boss 25 have the same shape and size. When the first boss 25 is embedded in the first groove 15, the gap between the first groove 15 and the first boss 25 will be reduced, thereby reducing the risk of water seepage. At the same time, since both the arc-shaped groove and the arc-shaped boss are curved structures, the installation between the first groove 15 and the first boss 25 will also be more flexible. When the first groove 15 is a square groove, the corresponding first boss 25 is a square boss. The first groove 15 and the first boss 25 have the same shape and size. When the first boss 25 is embedded in the first groove 15, the gap will also be reduced, thereby reducing the risk of water seepage.
[0051] Similarly, the third plane 132 has a second boss 16, and the fourth plane 232 has a second groove 26. The second boss 16 is embedded in the second groove 26, which can be either an arc-shaped groove or a square groove. Correspondingly, when the second groove 26 is an arc-shaped groove, the corresponding second boss 16 is an arc-shaped boss; when the second groove 26 is a square groove, the corresponding second boss 16 is a square boss. The second groove 26 and the second boss 16 have the same shape and size, which helps to reduce installation gaps during installation. When the first boss 25 is embedded in the first groove 15, and / or the second boss 16 is embedded in the second groove 26, it will help to tightly connect the upper side plate 12 and the lower side plate 22, allowing the upper shell 10 and the lower shell 20 to be connected more fully, thereby reducing the assembly gap between the upper shell 10 and the lower shell 20, and thus reducing the risk of water flowing into the body controller through the assembly gap.
[0052] In this embodiment of the application, when the third plane 132 is provided with the first boss 25, the first boss 25 is an elastic boss; when the fourth plane 232 is provided with the second boss 16, the second boss 16 is an elastic boss.
[0053] Specifically, when the first protrusion 25 is an elastic protrusion, during the installation of the first protruding structure 13 and the second protruding structure 23, the first protruding structure 13 needs to be pressed to interlock with the second protruding structure 23, that is, the first protrusion 25 will be interlocked in the first groove 15. Because the first protrusion 25 is an elastic protrusion, it will be compressed and deformed during the interlocking process, thus facilitating sliding. When the first protrusion 25 slides to the position of the first groove 15 and fits against it, it will return to its original shape and abut against the first groove 15, thereby completing the installation. Setting the first protrusion 25 as an elastic protrusion will further facilitate the fitting and installation of the first protrusion 25 and the first groove 15. Similarly, when the second protrusion 16 is an elastic protrusion, the same effect will be achieved.
[0054] In the embodiments of this application, such as Figure 5 As shown, a third protrusion 17 is provided on the first plane 131, a third groove 27 is provided on the second plane 231, the third protrusion 17 is embedded in the third groove 27, and / or, a fourth groove 18 is provided on the first plane 131, a fourth protrusion 28 is provided on the second plane 231, the fourth protrusion 28 is embedded in the fourth groove 18.
[0055] For example, in this embodiment of the application, a third protrusion 17 is provided on the first plane 131, and a third groove 27 is provided on the second plane 231. The third protrusion 17 is embedded in the third groove 27. The shape of the third protrusion 17 can be a wedge-shaped plate or a curved surface. The third groove 27 can also be a wedge-shaped groove or a curved surface groove. When the shape of the third protrusion 17 is a wedge-shaped plate, the end of the third protrusion 17 near the upper top plate 11 is the bottom of the wedge plate and has a larger width. The end of the third protrusion 17 away from the upper top plate 11 is the top of the wedge plate and has a smaller width. The width of the wedge plate gradually decreases from the bottom to the top of the third protrusion 17. At this point, the third groove 27 is also wedge-shaped, and its shape and size are the same as the wedge shape of the third boss 17. The end of the third groove 27 facing away from the lower base plate 21 is the bottom of the wedge, which is wider, while the end of the third groove 27 near the lower base plate 21 is the top of the wedge, which is narrower. The width of the wedge gradually decreases from the bottom to the top of the third groove 27. The third boss 17 and the third groove 27 are the same shape and size. When the third boss 17 is embedded in the third groove 27, the gap between the third boss 17 and the third groove 27 will be reduced, thereby reducing the risk of water seepage. In addition, when the third boss 17 is wedge-shaped, the thickness of the wedge plate is smaller, and correspondingly, the width of the third groove 27 is also set to be smaller. This not only facilitates the processing and manufacturing of the third boss 17 and the third groove 27, but also effectively reduces production costs. Meanwhile, when the third protrusion 17 is wedge-shaped, its thickness is less than the minimum thickness of the upper side plate 12, and it is arranged around the upper side plate 12, also serving as a water baffle. Water flows downwards along the upper side plate 12. Even if water can seep into the assembly gap between the upper side plate 12 and the lower side plate 22, the presence of the third protrusion 17 prevents further seepage, thus providing additional waterproofing. When the third protrusion 17 is curved, the third groove 27 is also curved, and the third protrusion 17 and the third groove 27 have the same shape and size. When the third protrusion 17 is embedded in the third groove 27, the gap between them is reduced, thereby lowering the risk of water leakage from the vehicle body controller.
[0056] A fourth groove 18 is provided on the first plane 131, and a fourth boss 28 is provided on the second plane 231. The fourth boss 28 is embedded in the fourth groove 18. The shape of the fourth boss 28 can be a wedge-shaped plate or a curved surface. The fourth groove 18 can also be a wedge-shaped groove or a curved surface groove. Only the third boss 17 and the third groove 27 can be provided, or only the fourth boss 28 and the fourth groove 18 can be provided, or all three can be provided simultaneously. When the third boss 17 is embedded in the third groove 27, and / or the fourth boss 28 is embedded in the fourth groove 18, it will help to connect the upper side plate 12 and the lower side plate 22, making the upper shell 10 and the lower shell 20 more tightly connected, thereby reducing the assembly gap between the upper shell 10 and the lower shell 20, and thus reducing the risk of water flowing into the body controller through the assembly gap.
[0057] like Figure 1 As shown, along the direction from the center of the upper top plate 11 to the edge of the upper top plate 11, the distance between the surface of the upper top plate 11 facing away from the lower bottom plate 21 and the lower bottom plate 21 gradually decreases.
[0058] For example, in this embodiment, the distance between the surface of the upper top plate 11 facing away from the lower bottom plate 21 and the outer surface of the lower bottom plate 21 gradually decreases along the direction from the center of the upper top plate 11 to the edge of the upper top plate 11, indicating that the surface of the upper top plate 11 facing away from the lower bottom plate 21 is convex. When water flows downward along the upper top plate 11, the water will flow quickly down from the convex surface along the direction from the center of the upper top plate 11 to the edge of the upper top plate 11, thereby avoiding water accumulation at the upper top plate 11. In addition, since the surface of the upper top plate 11 facing away from the lower bottom plate 21 is convex, when water flows downward along the upper top plate 11, the flow rate will increase due to gravity. Therefore, when the water flows through the assembly gap between the upper side plate 12 and the lower side plate 22, the water will quickly pass through the assembly gap, thereby reducing the risk of water seeping into the body control unit.
[0059] like Figure 3 As shown, the outer surface of the upper shell 10 is provided with a first drainage groove 14, and the outer surface of the lower side plate 22 is provided with a second drainage groove 24; the first drainage groove 14 and the second drainage groove 24 are connected.
[0060] For example, in this embodiment, the outer surface of the upper shell 10 is provided with a first drainage groove 14, that is, the outer surfaces of the upper top plate 11 and the upper side plate 12 are both provided with a first drainage groove 14. On the outer surface of the upper top plate 11, the direction of the first drainage groove 14 is along the direction from the center of the upper top plate 11 to the edge of the upper top plate 11. The first drainage groove 14 can extend in a straight line, in a curved direction, or in a combination of straight lines and curves. On the outer surface of the upper side plate 12, the direction of the first drainage groove 14 is along the direction from the edge of the upper top plate 11 to the edge of the lower bottom plate 21. The first drainage groove 14 can extend in a straight line, in a curved direction, or in a combination of straight lines and curves. The outer surface of the lower side plate 22 is provided with a second drainage groove 24. Similarly, the direction of the second drainage groove 24 is along the direction from the edge of the upper top plate 11 to the edge of the lower bottom plate 21. The second drainage groove 24 can extend in a straight line, in a curved direction, or in a combination of straight lines and curves. The first drainage channel 14 and the second drainage channel 24 are connected. When water flows downward along the first drainage channel 14, it flows into the second drainage channel 24 through the junction of the first and second drainage channels 14, until it flows out of the lower side plate 22 through the second drainage channel 24, thus draining the water. The first drainage channel 14 is provided on the outer surface of the upper shell 10, and the second drainage channel 24 is provided on the outer surface of the lower side plate 22, and the first and second drainage channels 14 are connected. This guides the water flow, helping it to flow quickly along the drainage channels, thereby preventing water accumulation on the upper shell 10 and lower shell 20, and reducing the risk of water entering the body controller. The number of drainage channels is not limited in this embodiment.
[0061] In this embodiment, the upper side plate 12 and the lower side plate 22 are connected to each other, and / or the upper top plate 11 and the lower bottom plate 21 are connected to each other.
[0062] For example, in this embodiment of the application, the upper side plate 12 and the lower side plate 22 are interconnected, including the inner wall of the upper side plate 12 and the inner wall of the lower side plate 22 being interconnected, and / or, the end face of the upper side plate 12 facing away from the upper top plate 11 and the end face of the lower side plate 22 facing away from the lower bottom plate 21 being interconnected. For the upper top plate 11 and the lower bottom plate 21, a mounting hole 31 can be provided on the upper top plate 11 and a mounting groove 32 can be provided on the lower bottom plate 21, and / or, a mounting groove 32 can be provided on the upper top plate 11 and a mounting hole 31 can be provided on the lower bottom plate 21. The fastener 30 passes through the mounting hole 31 and is embedded in the mounting groove 32 to connect the upper top plate 11 and the lower bottom plate 21 together. Connecting the upper side panel 12 to the lower side panel 22, and / or connecting the upper top panel 11 to the lower bottom panel 21, allows for a tighter connection between the upper shell 10 and the lower shell 20, thereby reducing the assembly gap between them and minimizing the risk of water flowing into the body controller through this gap. Simultaneously, connecting the upper side panel 12 to the lower side panel 22, and / or connecting the upper top panel 11 to the lower bottom panel 21, creates a unified structure between the upper shell 10 and the lower shell 20, facilitating the handling and installation of the body controller.
[0063] In the embodiments of this application, such as Figure 6 As shown, the lower base plate 21 has a fifth groove 211 on the plane opposite to the upper top plate 11. The bottom of the fifth groove 211 has a mounting hole 31. The upper top plate 11 has a mounting groove 32 on the surface facing the lower base plate 21. The fastener 30 passes through the mounting hole 31 and is embedded in the mounting groove 32. The fastener 30 is fixedly connected to the mounting groove 32 to fix the upper top plate 11 and the lower base plate 21.
[0064] For example, in this embodiment of the application, the fastener 30 connects the lower shell 20 and the upper shell 10 together through the mounting hole 31 and the mounting groove 32. The mounting hole 31 is located at the bottom of the fifth groove 211 on the lower bottom plate 21 facing away from the plane of the upper top plate 11, and the mounting groove 32 is located on the surface of the upper top plate 11 facing the lower bottom plate 21. Connecting the lower shell 20 and the upper shell 10 through the fastener 30 further constrains them, thus further reducing the assembly gap between them and reducing the risk of water seeping into the gap between them.
[0065] Specifically, in the embodiments of this application, the fastener 30 can be a common bolt, an expansion bolt, or a rivet, or other structures, such as... Figure 6As shown, when the fastener 30 is a regular bolt, the bolt shank is threaded, and the inner walls of the mounting hole 31 and mounting groove 32 are also threaded. The regular bolt can be screwed through the mounting hole 31 and further screwed into the mounting groove 32. Through the engagement of the threaded bolt and the hole / groove, the bolt can be fixedly connected to the mounting hole 31 and mounting groove 32, thereby fixing the lower shell 20 and the upper shell 10. Since the mounting hole 31 penetrates the lower base plate 21, and the mounting groove 32 does not penetrate the upper top plate 11, a nut is not required when installing the fastener 30. The bolt of the fastener 30 can be directly screwed into the mounting groove 32 through the mounting hole 31, which not only saves production costs but also improves installation efficiency. Figure 7 As shown, when the fastener 30 is an expansion bolt, the expansion bolt can be directly inserted into the mounting groove 32 through the mounting hole 31. Then, by rotating the nut at the end of the expansion bolt, the bolt thread will be pulled outwards, causing the steel plate of the expansion bolt to expand. Due to the friction generated by the pressure between the steel plate and the inner wall of the mounting groove 32, the expansion bolt is fixedly connected to the mounting groove 32, thereby fixing the lower shell 20 and the upper shell 10 together. Figure 8 As shown, when the fastener 30 is a rivet, the rivet can be directly inserted into the mounting groove 32 through the mounting hole 31. Since there are gaps between the rivet and the mounting hole 31 and the mounting groove 32, metal glue can be added to the gaps to fix the rivet to the mounting hole 31 and the mounting groove 32, thereby fixing the lower shell 20 and the upper shell 10 together.
[0066] Specifically, in this embodiment, the mounting hole 31 is located at the bottom of the fifth groove 211 on the lower base plate 21 away from the plane of the upper top plate 11, and the head thickness of the fastener 30 is less than the depth of the fifth groove 211. After the fastener 30 is installed, since the head thickness of the fastener 30 is less than the depth of the fifth groove 211, the fastener 30 will not protrude from the outer surface of the lower base plate 21. On the one hand, this can prevent the fastener 30 from being subjected to force and thus pressing the mounting hole 31. On the other hand, it also helps to maintain the flatness of the lower base plate 21, which is beneficial for the placement of the vehicle body controller.
[0067] Specifically, in this embodiment, the fifth groove 211 can be circular or rectangular, and its area is slightly larger than the area of the head of the fastener 30. A circular or rectangular shape facilitates processing, and the smaller thickness of the fifth groove 211 helps further reduce the production cost of the vehicle body controller. Simultaneously, the slightly larger area of the fifth groove 211 compared to the head of the fastener 30 satisfies the installation requirements of the fastener 30 while also effectively saving costs.
[0068] For example, in this embodiment, the fastener 30 is made of stainless steel. Stainless steel has extremely strong corrosion resistance, maintaining its performance in various harsh environments without rusting or corroding. Furthermore, stainless steel is durable and maintains its strength and luster over long-term use, contributing to the long-term use of the fastener 30. The fastener 30 is an internal angle bolt, a special type of bolt with rounded or wedge-shaped threads. Internal angle bolts are suitable for fastening scenarios where the space is confined and subjected to lateral or longitudinal loads. They can provide sufficient fastening force within a limited space and prevent deformation at the load-bearing area. Therefore, using internal angle bolts facilitates installation and ensures the strength of the fastener 30, preventing damage.
