Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to a body pillar assembly and a vehicle. Background Technology

[0002] Vehicle safety has always been a crucial consideration in automotive design, especially in the event of a collision, where the strength and rigidity of the vehicle body structure directly affect occupant safety. Pillars, such as the B-pillar, are key structural components on the side of the vehicle and play a vital role in side impacts. Their primary function is to absorb and disperse collision energy, preventing excessive deformation of the vehicle body and thus protecting the safety of the occupants.

[0003] However, with the increasing demand for vehicle lightweighting, improving the strength and rigidity of the pillars without significantly increasing the vehicle's weight has become a technical challenge. While traditional steel possesses high strength, its weight is substantial, which is detrimental to the energy efficiency of new energy vehicles. Therefore, in vehicle design, improving the rigidity and strength of the pillars while ensuring vehicle lightweighting is crucial for enhancing vehicle safety performance. Utility Model Content

[0004] In view of this, this application provides a body pillar assembly and a vehicle, which forms a multi-layer composite structure body pillar assembly by combining outer sheet metal parts, inner sheet metal parts, reinforcing parts and auxiliary reinforcing parts, which is beneficial to improve the rigidity and strength of the pillar while ensuring the vehicle is lightweight.

[0005] In a first aspect, this application provides a vehicle body pillar assembly for a vehicle, comprising: an outer sheet metal part; an inner sheet metal part arranged opposite to the outer sheet metal part; a reinforcing member disposed between the outer sheet metal part and the inner sheet metal part, and connected to the inner sheet metal part and the outer sheet metal part respectively; and a supplementary reinforcement member disposed between the reinforcing member and the inner sheet metal part, and connected to the inner sheet metal part and the reinforcing member respectively.

[0006] The vehicle body pillar assembly of this application forms a multi-layered composite structure through the combination of outer sheet metal parts, inner sheet metal parts, reinforcing parts, and auxiliary reinforcing parts, which is beneficial for achieving vehicle lightweighting. Simultaneously, the outer and inner sheet metal parts form the external structure of the vehicle body pillar assembly, providing a certain degree of connection and support to the vehicle body. The reinforcing parts connect to both the inner and outer sheet metal parts, forming the load-bearing support structure of the vehicle body pillar assembly, effectively absorbing and dispersing collision energy and reducing the intrusion into the passenger compartment during a collision. The auxiliary reinforcing parts are located between the reinforcing parts and the inner sheet metal parts, further improving the structural strength of the vehicle body pillar assembly. Thus, while achieving vehicle lightweighting, the structural strength of the vehicle body pillar assembly is also improved.

[0007] In some embodiments, the reinforcing member includes: a first plate body; and two first side plates, the two first side plates being located on both sides of the first plate body along the front-rear direction of the vehicle, the first side plates extending towards the interior of the vehicle along the left-right direction of the vehicle, and the first side plates being used to connect the reinforcing member and the inner sheet metal part.

[0008] The reinforcing component connects to the reinforcing component and the inner sheet metal component through the first side plate, transferring the impact force from the reinforcing component to the inner sheet metal component, dispersing the impact energy, reducing intrusion into the passenger compartment, and improving vehicle safety.

[0009] According to some embodiments of this application, each of the first side panels has a first connecting flange at one end away from the first panel body in the left-right direction of the vehicle; the reinforcing member includes a second panel body and second side panels located on both sides of the second panel body in the front-rear direction of the vehicle, and the second side panels have a second connecting flange at one end away from the second panel body in the left-right direction of the vehicle; the inner sheet metal part includes a third panel body and third side panels located on both sides of the third panel body in the front-rear direction of the vehicle, and the third side panels have a third connecting flange at one end away from the third panel body in the left-right direction of the vehicle; the third connecting flange and the second connecting flange are respectively located on both sides of the first connecting flange, and are both welded to the first connecting flange.

[0010] In this way, the first, second, and third flanges form a multi-layered connection structure. When the vehicle is involved in a collision, the multi-layered connection structure can provide the body pillar assembly with higher resistance to deformation, reduce the intrusion of the body pillar assembly into the passenger compartment, and help to further improve the safety of the vehicle.

[0011] According to some embodiments of this application, the first connecting flange includes a plurality of sub-flaps spaced apart along the vehicle height direction; and / or, the first plate body includes a plurality of plate segments sequentially distributed from top to bottom along the vehicle height direction, wherein two adjacent plate segments are not on the same plane.

[0012] Multiple sub-flanges provide multiple connection points distributed along the vehicle height for the connection and installation of the reinforcing components, which helps to improve the overall rigidity and structural stability of the body pillar assembly. The main body of the first plate is set up as multiple plate segments, providing different support and deformation resistance for the body pillar assembly at different heights and in different directions.

[0013] According to some embodiments of this application, the first side plate is provided with a first recessed portion that is concave outward along the vehicle front-rear direction away from the reinforcing member and a first protruding portion that is convex inward along the vehicle front-rear direction toward the reinforcing member. The first protruding portion and the first recessed portion are arranged alternately along the vehicle height direction. The first recessed portion is used for welding to the second side plate, and the first protruding portion constitutes a reinforcing structure.

[0014] By introducing staggered first recesses and first protrusions on the first side plate, not only is the structural integrity and impact resistance of the column improved, but it also provides greater flexibility for manufacturing and assembly.

[0015] According to some embodiments of this application, the first plate body is provided with a second protrusion that protrudes outward in the direction away from the vehicle interior and a second recess that is recessed in the direction closer to the vehicle interior in the direction of the vehicle interior. The second protrusion is provided with a welding positioning hole for welding to the second plate body; the second recess constitutes a reinforcing structure.

[0016] The combined design of the second concave portion and the second convex portion enables the main body of the first plate to provide support and reinforcement for the vehicle body pillar assembly in the front-rear direction, further improving the overall strength and rigidity of the pillar.

[0017] According to some embodiments of this application, the second recess is provided with a weight-reducing hole.

[0018] By introducing weight-reduction holes, the vehicle body pillar assembly can be made lighter without sacrificing safety performance, which helps to extend the vehicle's driving range.

[0019] According to some embodiments of this application, the reinforcing member further includes a first fixing plate located at the bottom of the first plate body and the first side plate, the first fixing plate having a plurality of first connecting holes; the reinforcing member includes a second fixing plate arranged in a stacked manner opposite to the first fixing plate, the second fixing plate having a second connecting hole; the outer sheet metal part includes a third fixing plate arranged in a stacked manner opposite to the second fixing plate, the third fixing plate having a third connecting hole; the body pillar assembly further includes a sill beam, the sill beam having a fourth connecting hole; the third fixing plate, the second fixing plate, the first fixing plate and the sill beam are connected by fasteners passing through the third connecting hole, the second connecting hole, the first connecting hole and the fourth connecting hole in sequence.

[0020] In this way, by passing fasteners through the third, second, first, and fourth connecting holes in sequence, the first fixing plate, the second fixing plate, and the third fixing plate are fixedly connected to the sill beam. This multi-layered connection method helps to ensure a tight fit between the components and improves the impact resistance and durability of the overall structure of the body pillar assembly.

[0021] According to some embodiments of this application, along the left-right direction of the vehicle, the first fixing plate is located outside the body of the first plate, and the reinforcing member further includes: a first transition plate, wherein the first fixing plate and the body of the first plate are connected through the first transition plate.

[0022] The connection of the first transition plate and the first plate body forms a more stable whole, which is conducive to improving the overall rigidity and structural strength of the vehicle body pillar assembly.

[0023] Secondly, embodiments of this application also provide a vehicle, including: the aforementioned body pillar assembly.

[0024] The vehicle described in this application, by using the aforementioned body pillar assembly, forms a multi-layered structure including reinforcing members and auxiliary reinforcing members. While meeting the requirements for vehicle lightweighting, it improves the structural strength of the vehicle. In the event of a side collision, the vehicle can more effectively absorb and disperse impact energy, thereby reducing intrusion into the passenger compartment and improving the vehicle's driving safety.

[0046] With the increasing demand for lightweight vehicles, improving the strength and rigidity of the pillars without significantly increasing vehicle weight has become a technical challenge. While traditional steel possesses high strength, its weight is substantial, which is detrimental to the energy efficiency of new energy vehicles. Therefore, in vehicle design, enhancing the rigidity and strength of the pillars while ensuring vehicle lightweighting is crucial for improving vehicle safety performance.

[0047] In view of this, the present application provides a vehicle body pillar assembly and a vehicle, which forms a multi-layer composite structure of vehicle body pillar assembly by combining outer sheet metal parts, inner sheet metal parts, reinforcing parts and auxiliary reinforcing parts, which is beneficial to improve the rigidity and strength of the pillar while ensuring vehicle lightweighting.

[0048] refer to Figures 1 to 7 In a first aspect, embodiments of this application provide a vehicle body pillar assembly 100 for use in a vehicle. The vehicle body pillar assembly 100 can be any one of an A-pillar assembly, a B-pillar assembly, or a C-pillar assembly, and is particularly suitable for pillar assemblies. The following description uses the vehicle body pillar assembly 100 as an example of a pillar assembly.

[0049] The vehicle body pillar assembly 100 in this embodiment may include an outer sheet metal part 110, an inner sheet metal part 120, a reinforcing part 130, and a supplementary reinforcing part 140.

[0050] refer to Figure 1 and Figure 2 and Figure 3 The inner sheet metal part 120 and the outer sheet metal part 110 are arranged opposite to each other to form the external structure of the body pillar assembly 100, which is connected to other structures of the body (such as the upper side beam) to form a complete body structure.

[0051] The reinforcing member 130 is disposed between the outer sheet metal part 110 and the inner sheet metal part 120, and is connected to both the inner sheet metal part 120 and the outer sheet metal part 110 respectively. For example, the reinforcing member 130 can be connected to the inner sheet metal part 120 and the outer sheet metal part 110 by welding, or the reinforcing member 130 can be connected to the inner sheet metal part 120 and the outer sheet metal part 110 respectively by screws or other connecting parts. The reinforcing member 130 connects the outer sheet metal part 110 and the inner sheet metal part 120 into an integral structure, which helps to absorb and disperse the energy generated by a vehicle collision, thereby reducing the intrusion into the passenger compartment when the body pillar assembly 100 deforms.

[0052] Optionally, at least one of the outer sheet metal part 110 and the inner sheet metal part 120 may be recessed away from the other to form a mounting cavity, facilitating the installation of the reinforcing member 130 and the auxiliary reinforcing member 140. For example, a portion of the outer sheet metal part 110 may be recessed away from the inner sheet metal part 120 to form a mounting cavity; alternatively, a portion of the inner sheet metal part 120 may be recessed away from the outer sheet metal part 110 to form a mounting cavity; or, opposing portions of the outer sheet metal part 110 and the inner sheet metal part 120 may be relatively far from the recess to form a mounting cavity. Furthermore, the reinforcing member 130 may be embedded within the mounting cavity to improve the installation stability of the reinforcing member 130 and the structural reliability of the vehicle body pillar assembly 100.

[0053] Furthermore, a portion of the structure of the reinforcing member 130 may be recessed away from either the inner sheet metal part 120 or the outer sheet metal part 110 to form a cavity for installing the reinforcing member 140. For example, the reinforcing member 130 may be recessed away from the inner sheet metal part 120 to form a cavity for installing the reinforcing member 140, or the reinforcing member 130 may be recessed away from the outer sheet metal part 110 to form a cavity for installing the reinforcing member 140, thereby improving the structural stability of the body pillar assembly 100.

[0054] The reinforcing member 140 is located between the reinforcing member 130 and the inner sheet metal member 120, and is connected to the inner sheet metal member 120 and the reinforcing member 130 respectively. The reinforcing member 140 provides additional support for the body pillar assembly 100, which helps to further improve the structural strength of the body pillar assembly 100.

[0055] The vehicle body pillar assembly 100 of this embodiment forms a multi-layered composite structure through the combination of an outer sheet metal part 110, an inner sheet metal part 120, a reinforcing member 130, and a supplementary reinforcing member 140, which is beneficial for achieving vehicle lightweighting. Simultaneously, the outer sheet metal part 110 and the inner sheet metal part 120 form the external structure of the vehicle body pillar assembly 100, providing a certain connection and support for the vehicle body. The reinforcing member 130 is connected to both the inner sheet metal part 120 and the outer sheet metal part 110, forming the load-bearing support structure of the vehicle body pillar assembly 100, effectively absorbing and dispersing collision energy and reducing the intrusion into the passenger compartment during a collision. The supplementary reinforcing member 140 is located between the reinforcing member 130 and the inner sheet metal part 120, further improving the structural strength of the vehicle body pillar assembly 100. Thus, while achieving vehicle lightweighting, the structural strength of the vehicle body pillar assembly 100 is also improved.

[0056] refer to Figure 1 and Figure 4 In some embodiments, the reinforcing member 140 may include: a first plate body 141 and a first side plate 142, wherein there are two first side plates 142, and the two first side plates 142 are respectively located on the first plate body 141 along the vehicle front-rear direction (e.g., Figure 1 On both sides of the vehicle in the X direction, the first side plate 142 is along the left and right directions of the vehicle (e.g., in the X direction). Figure 1 Extending in the Y direction (as shown in the diagram) towards the interior of the vehicle, the first side plate 142 is used to connect the reinforcing member 130 and the inner sheet metal part 120. For example, the reinforcing member 130 and the inner sheet metal part 120 can be connected by welding their respective sides to them. Alternatively, the first side plate 142, the reinforcing member 130, and the inner sheet metal part 120 can be provided with coaxial through holes, through which fasteners 160 such as bolts or screws are passed to fix the first side plate 142, the reinforcing member 130, and the inner sheet metal part 120 together. The through holes on the first side plate 142, the reinforcing member 130, and the inner sheet metal part 120 can be in the same position, or the through holes on the first side plate 142 and the reinforcing member 130 can be in the same position, while the through holes on the first side plate 142 and the inner sheet metal part 120 correspond to each other in another position.

[0057] Thus, the reinforcing member 140 connects the reinforcing member 130 and the inner sheet metal member 120 through the first side plate 142, transferring the collision force from the reinforcing member 130 to the inner sheet metal member 120, dispersing the impact energy, reducing intrusion into the passenger compartment, and improving vehicle safety.

[0058] refer to Figure 1 , Figure 4 and Figure 7According to some embodiments of this application, each first side panel 142 is provided with a first connecting flange 1421. The first connecting flange 1421 is located at the end of the first side panel 142 away from the first panel body 141 in the left-right direction of the vehicle. The first connection enables the first side panel 142 to be more securely connected to other components, providing additional structural support for the body pillar assembly 100.

[0059] The reinforcing member 130 may include a second plate body 131 and a second side plate 132. The second side plate 132 is located on both sides of the second plate body 131 in the vehicle front-rear direction. The second side plate 132 is provided with a second connecting flange 1321. The second connecting flange 1321 is located at the end of the second side plate 132 away from the second plate body 131 in the vehicle left-right direction. The second connecting flange 1321 provides a structural basis for the reinforcing member 130 to connect with other structures.

[0060] The inner sheet metal part 120 may include a third plate body 121 and a third side plate 122. The third side plate 122 is located on both sides of the third plate body 121 along the front-rear direction of the vehicle. The third side plate 122 is provided with a third connecting flange 1221. The third connecting flange 1221 is located at the end of the third side plate 122 away from the third plate body 121 along the left-right direction of the vehicle. The third connecting flange 1221 provides a structural basis for the inner sheet metal part 120 to connect with other structures.

[0061] The third connecting flange 1221 and the second connecting flange 1321 are located on both sides of the first connecting flange 1421, and are both welded to the first connecting flange 1421. Specifically, the third connecting flange 1221 is located on the side of the first connecting flange 1421 facing the inside of the vehicle, and the second connecting flange 1321 is located on the side of the first connecting flange 1421 facing the outside of the vehicle.

[0062] Thus, the first, second, and third flanges form a multi-layered connection structure. When the vehicle is involved in a collision, the multi-layered connection structure can provide the body pillar assembly 100 with higher resistance to deformation, reduce the intrusion of the body pillar assembly 100 into the passenger compartment, and help to further improve the safety of the vehicle.

[0063] refer to Figure 4 , Figure 5 and Figure 6 According to some embodiments of this application, the first connecting flange 1421 may include a plurality of sub-flaps 1421a, the plurality of sub-flaps 1421a being along the vehicle height direction (e.g., Figure 1 The sub-flanges 1421a are spaced apart in the Z direction. In this way, multiple connection points distributed along the vehicle height direction are provided for the connection and installation of the reinforcing member 140 through multiple sub-flanges 1421a, which helps to improve the overall rigidity and structural stability of the body pillar assembly 100.

[0064] The first plate body 141 may include multiple plate segments, which are sequentially distributed from top to bottom along the vehicle height direction. Adjacent plate segments are not on the same plane; for example, adjacent plate segments may form an angle, or one of adjacent plate segments may be an arc surface and the other a plane, or the multiple plate segments may extend in a curve along the vehicle height direction. In this embodiment, the specific structure of the multiple plate segments can be designed by the engineer according to the specific installation position of the reinforcing member 140 to improve the installation flexibility of the reinforcing member 140.

[0065] By setting the first plate body 141 into multiple non-coplanar plate segments, different support functions and anti-deformation capabilities are provided for the body pillar assembly 100 at different heights and in different directions.

[0066] Continue to refer to Figure 4 According to some embodiments of this application, the first side plate 142 is provided with a first recess 1422 and a first protrusion 1423. The first recess 1422 is recessed outward from the inner cavity of the reinforcing member 140 along the vehicle's front-rear direction, and the first protrusion 1423 protrudes towards the inner cavity of the reinforcing member 140 along the vehicle's front-rear direction. The first protrusion 1423 and the first recess 1422 are arranged alternately along the vehicle's height direction. The first recess 1422 is used for welding with the second side plate 132. On the side of the first side plate 142 facing outward along the vehicle's front-rear direction, the first recess 1422 forms a structure that protrudes towards the reinforcing member 130. The second side plate 132 is bonded to the surface of multiple first recesses 1422 facing outward along the vehicle's left-right direction, forming a multi-point welding structure, which is beneficial to improving the connection strength between the reinforcing plate and the reinforcing member 140.

[0067] Along the height direction of the vehicle, multiple first protrusions 1423 form spaced reinforcing ribs, constituting a reinforcing structure, which improves the structural rigidity of the first side plate 142 and can more effectively resist deformation when the vehicle collides.

[0068] By introducing staggered first recesses 1422 and first protrusions 1423 on the first side plate 142, not only is the structural integrity and impact resistance of the column improved, but also greater flexibility is provided for manufacturing and assembly.

[0069] Continue to refer to Figure 4According to some embodiments of this application, the first plate body 141 has a second protrusion 1411 and a second recess 1412. The second protrusion 1411 protrudes outward along the left-right direction of the vehicle and away from the interior of the vehicle. The second protrusion 1411 provides a structural basis for the connection between the first plate body 141 and the second plate body 131. The second plate body 131 can be welded to the protruding surface of the second protrusion 1411. The second protrusion 1411 is provided with a welding positioning hole 1411a, which is used for welding with the second plate body 131. Exemplarily, when the first plate body 141 and the second plate body 131 are aligned, the operator can weld the peripheral wall of the welding positioning hole 1411a to the second plate body 131 for fixation. This operation is convenient and facilitates the assembly and fixation between the reinforcing member 130 and the supplementary reinforcing member 140. Alternatively, the second plate body 131 can be provided with a mating structure corresponding to the welding positioning. For example, the mating structure can be a positioning protrusion protruding towards the first plate body 141, which passes through the welding positioning hole 1411a to align the first plate body 141 and the second plate body 131. Alternatively, the mating structure can also be a positioning mating hole. When the welding positioning hole 1411a aligns with the positioning mating hole, the first plate body 141 and the second plate body 131 are positioned and welded. This improves the assembly accuracy between the reinforcing plate and the supplementary reinforcing plate.

[0070] The second recess 1412 is recessed inward along the left-right direction of the vehicle and closer to the interior of the vehicle, and the second protrusion 1411 forms a reinforcing rib, constituting a reinforcing structure, which enhances the deformation resistance of the first plate body 141, especially in the event of a side collision, it can more effectively absorb and disperse energy.

[0071] The combined design of the second recess 1412 and the second protrusion 1411 enables the first plate body 141 to provide support and reinforcement for the vehicle body pillar assembly 100 in the front-rear direction, further improving the overall strength and rigidity of the pillar.

[0072] refer to Figure 4 According to some embodiments of this application, the second recess 1412 is provided with a weight-reducing hole 1412a. Exemplarily, the weight-reducing hole 1412a can be a square hole, a round hole, or a strip hole, etc. By introducing the weight-reducing hole 1412a, the vehicle body pillar assembly 100 can achieve weight reduction without sacrificing safety performance, which is beneficial to extending the vehicle's driving range.

[0073] refer to Figure 1 , Figure 2 and Figure 4According to some embodiments of this application, the reinforcing member 140 may further include a first fixing plate 143 located at the bottom of the first plate body 141 and the first side plate 142. The first fixing plate 143 is provided with a plurality of first connecting holes 1431. The reinforcing member 130 includes a second fixing plate 133. The second fixing plate 133 is arranged in a stacked manner with the first fixing plate 143 facing each other inside and out. The second fixing plate 133 is provided with a second connecting hole 1331. The outer sheet metal part 110 includes a third fixing plate 111, which is arranged in a stacked manner with the second fixing plate 133 facing each other. The third fixing plate 111 is provided with a third connecting hole 1111. The body pillar assembly 100 may also include a sill beam 150, which is provided with a fourth connecting hole 151. The third fixing plate 111, the second fixing plate 133, the first fixing plate 143 and the sill beam 150 are connected by fasteners 160 passing through the third connecting hole 1111, the second connecting hole 1331, the first connecting hole 1431 and the fourth connecting hole 151 in sequence.

[0074] Thus, by passing fasteners 160 sequentially through the third connecting hole 1111, the second connecting hole 1331, the first connecting hole 1431, and the fourth connecting hole 151, the first fixing plate 143, the second fixing plate 133, the third fixing plate 111 are fixedly connected to the sill beam 150. This multi-layered connection method helps to ensure a tight fit between the components and improves the impact resistance and durability of the overall structure of the body pillar assembly 100.

[0075] Optionally, fastener 160 may include standard parts such as bolts, nuts, and screws to save on production costs.

[0076] refer to Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 Furthermore, the sill beam 150 has a first wall and a second wall arranged along the left-right direction of the vehicle, with the second wall located on the side of the first wall facing the interior of the vehicle, and the fourth connecting hole 151 located on the first wall. The inner sheet metal part 120 may also include a fourth fixing plate located below the third plate body 121, the fourth fixing plate being provided with a fifth connecting hole, and the second wall being provided with a sixth connecting hole, with the connector passing through the fifth and sixth connecting holes, thereby fixing the fourth fixing plate to the sill beam 150.

[0077] Thus, the bottom of the structure formed by the inner sheet metal part 120, the outer sheet metal part 110, the reinforcing part 130 and the supplementary reinforcing part 140 covers multiple surfaces of the sill beam 150, which helps to improve the integrity of the body pillar assembly 100. At the same time, it makes the lower end of the body pillar assembly 100 form a closed structure, which helps to continuously and smoothly disperse the impact force and improve the safety of the vehicle.

[0078] refer to Figure 1 , Figure 2 and Figure 4 According to some embodiments of this application, along the left-right direction of the vehicle, the first fixing plate 143 is located outside the first plate body 141. In other words, the first fixing plate 143 and the first plate body 141 form a stepped structure along the left-right direction of the vehicle to facilitate the positioning and installation of the reinforcement 130 when it is connected to the sill beam 150.

[0079] The reinforcing member 140 may further include a first transition plate 144, through which the first fixing plate 143 and the first plate body 141 are connected. By introducing the first transition plate 144, the connection between the first fixing plate 143 and the first plate body 141 becomes smooth and continuous, which helps reduce concentration on the reinforcing member 140. Simultaneously, through the connection of the first transition plate 144, the first fixing plate 143 and the first plate body 141 form a more stable whole, which helps improve the overall rigidity and structural strength of the vehicle body pillar assembly 100.

[0080] Secondly, embodiments of this application also provide a vehicle, which may include the aforementioned body pillar assembly 100.

[0081] The vehicle described in this application, by using the aforementioned body pillar assembly 100, forms a multi-layer structure including reinforcing members 130 and supplementary reinforcing members 140. While meeting the requirements for vehicle lightweighting, it improves the structural strength of the vehicle. In the event of a side collision, the vehicle can more effectively absorb and disperse impact energy, thereby reducing intrusion into the passenger compartment and improving the vehicle's driving safety.

[0082] It should be noted that the vehicle in this application can refer to large vehicles, small vehicles, special-purpose vehicles, etc. For example, according to vehicle type, the vehicle in this application can be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV), or other types of vehicles. Generally, a vehicle is equipped with wheels, a power source, and a transmission system between the wheels and the power source. The transmission system can transmit the power provided by the power source to the wheels, causing the wheels to rotate and thus driving the vehicle.

[0083] It should be noted that the type of power source for the vehicle is not limited in this embodiment. For example, for gasoline vehicles, the power source can refer to a gasoline engine, diesel engine, or other fuel-powered engine; for electric vehicles, the power source can refer to an electric motor; for hybrid vehicles, the power source can refer to either an engine or an electric motor; and for vehicles powered by other means, the power source can refer to any device that generates power.
