It should be noted that the direction mark is only used to describe the present application, but is not used to limit the scope of the present application.

[0035] With the development of vehicles, the number of electrical components on vehicles is increasing. Due to the limitation of the installation space in the passenger compartment, some electrical components need to be installed outside the passenger compartment, such as at the bottom of the vehicle body.

[0036] In the related art, a threaded hole is provided at the bottom of the vehicle body. Figure 1, a fixing circular hole 11 is provided on the electrical component 1, and the fastener passes through the fixing circular hole 11 and the threaded hole in sequence to fix the electrical component 1 to the bottom of the vehicle body. When the electrical component 1 is installed at the bottom of the vehicle body, a dedicated person is required to first lift the electrical component 1 to the installation position at the bottom of the vehicle body, and then a dedicated person fixes the electrical component. The entire installation process requires at least two people to cooperate to complete, and there is a problem of low installation efficiency. In addition, the space at the bottom of the vehicle body is small, and two people will be crowded together at the bottom of the vehicle body, which can easily cause fatigue to the installer.

[0037] In order to solve the above problems, an embodiment of the present application provides a vehicle. Here, it needs to be explained that the vehicle mentioned in the embodiment of the present application may refer to a large car, a small car, a special-purpose vehicle, etc. For example, according to the vehicle model, the vehicle in the embodiment of the present application may refer to a sedan model, an off-road model, or a multi-purpose vehicle (MPV) or other models.

[0038] Reference Figure 2 In the embodiment of the present application, the vehicle includes a vehicle body 2, an electrical device 3, and a connection assembly component 4, and the vehicle body 2 and the electrical device 3 are connected via the connection assembly component 4. When installing the electrical device 3, the electrical device 3 can be fixed to the bottom of the vehicle body 2 via the connection assembly component 4 to improve the installation efficiency of the electrical device 3 at the bottom of the vehicle body 2.

[0039] In the embodiment of the present application, there are many possible types of the electrical device 3, for example, the electrical device 3 can be a controller, an air bag sensor, or an anti-lock brake system sensor, which is not limited in the embodiment of the present application. In one possible implementation provided in the embodiment of the present application, the electrical device 3 is a controller.

[0040] Reference Figure 2 , Figure 3 and Figure 4The embodiment of the present application further provides a connection assembly component 4, which includes a first connection member 41, a second connection member 42, a pre-hanging component 43 and a fixing component 44, wherein the first connection member 41 is used to be arranged on the vehicle body 2; the second connection member 42 is used to be arranged on the electrical device 3; the pre-hanging component 43 includes a hanging member 431 and a matching member 432, the hanging member 431 has a hanging portion 4311, and the matching member 432 has a matching portion 4322, the hanging portion 4311 can be matched with the matching portion 4322 in the gravity direction, and the hanging member 4311 can be matched with the matching portion 4322 in the gravity direction. 31 and the matching part 432 are arranged on the first connecting member 41, and the other is arranged on the second connecting member 42; the fixing assembly 44 includes a first fixing member 441 and a second fixing member 442, one of the first fixing member 441 and the second fixing member 442 is arranged on the first connecting member 41, and the other is arranged on the second connecting member 42, when the hanging part 4311 and the matching part 4322 are matched along the gravity direction, the first fixing member 441 cooperates with the second fixing member 442 to fix the first connecting member 41 and the second connecting member 42.

[0041] In the embodiment of the present application, there are many ways for the first connecting member 41 to be arranged on the vehicle body 2. For example, the connection between the first connecting member 41 and the vehicle body 2 can be integrated, clamped, bonded, welded, connected with fasteners, etc., which is not limited in the embodiment of the present application. There are many ways for the second connecting member 42 to be arranged on the electrical device 3. For example, the connection between the second connecting member 42 and the electrical device 3 can be integrated, clamped, bonded, welded, connected with fasteners, etc., which is not limited in the embodiment of the present application.

[0042] The connection assembly component 4 provided in the present application has a first connection member 41 for being arranged on the vehicle body 2, and a second connection member 42 for being arranged on the electrical device 3. The electrical device 3 is fixedly mounted on the bottom of the vehicle body 2 through the first connection member 41 and the second connection member 42. The pre-hanging component 43 includes a matching member 432 and a hanging member 431. The matching member 432 is arranged on the first connection member 41, and the hanging member 431 is arranged on the second connection member 42. The hanging member 431 has a hanging portion 4311, and the matching member 432 has a matching portion 4322. The hanging portion 4311 can be matched with the matching portion 4322 in the direction of gravity. When installing the electrical device 3, the hanging portion 4311 on the hanging member 431 can be matched with the matching portion 4322 on the matching member 432 in the direction of gravity so that the electrical device 3 is pre-hanged on the bottom of the vehicle body 2, and then the first connection member 41 and the second connection member 42 are fixed by the fixing component 44 to realize the installation of the electrical device 3 on the vehicle body 2. The fixing assembly 44 includes a first fixing member 441 and a second fixing member 442, one of which is arranged on the first connecting member 41, and the other is arranged on the second connecting member 42. When the hanging portion 4311 and the matching portion 4322 are matched in the direction of gravity, the first fixing member 441 can match with the second fixing member 442 to fix the first connecting member 41 and the second connecting member 42. Compared with the solution in the related art that a special person is required to lift the electrical device 3 to the installation position at the bottom of the vehicle body 2 and then fix the electrical device 3 by a special person, the connection assembly assembly 4 of the present application includes a pre-hanging assembly 43. When installing the electrical device 3, the second connecting member 42 on the electrical device 3 can be hung on the first connecting member 41 on the vehicle body 1 through the pre-hanging assembly 43. Therefore, when fixing the electrical device 3, it is not necessary to lift the electrical device 3, so that the installation of the electrical device 3 can be completed independently by a single person, thereby improving the installation efficiency of the electrical device 3. In addition, reducing the number of people required to install the electrical device 3 can prevent the installers from getting tired due to crowding under the vehicle.

[0043] In the embodiment of the present application, the function of the hanging part 4311 on the hanging member 431 is to stop and cooperate with the matching part 4322 on the matching member 432 in the direction of gravity. Therefore, there are many possibilities for the structural design of the hanging part 4311 and the matching part 4322. For example, the hanging part 4311 can be a hook, and the matching part 4322 can be a hooking protrusion. When installing the electrical device 3, the hook and the hooking protrusion can be stopped and cooperated in the direction of gravity first, so that the electrical device 3 is pre-hung on the bottom of the vehicle body 2.

[0044] Reference Figure 3 , Figure 4 and Figure 5In an implementable method provided in an embodiment of the present application, the hanging portion 4311 is a hanging hole, the hanging hole has a hanging section 43111 and a guide section 43112, the mating piece 432 has an insertion portion 4321, the mating portion 4322 is arranged on the insertion portion 4321, in the extension direction of the hanging hole, the insertion portion 4321 can be inserted into the hanging section 43111 through the guide section 43112, the size of the hanging section 43111 is smaller than the outer diameter of the mating portion 4322, so that the mating portion 4322 and the hanging section 43111 are stopped and matched in the gravity direction. When installing the electrical device 3, the insertion portion 4321 can be inserted into the hanging section 43111 through the guide section 43112. At this time, the matching portion 4322 on the insertion portion 4321 is matched with the hanging section 43111 in the direction of gravity. Because the size of the hanging section 43111 is smaller than the outer diameter of the matching portion 4322, the matching portion 4322 and the hanging section 43111 can be matched with each other in the direction of gravity, thereby realizing the pre-hanging of the electrical device 3 at the bottom of the vehicle body 2. Here, the hanging section 4311 is a hanging hole, and the edge of the hanging section 43111 can be matched with the matching portion 4322, thereby increasing the contact area between the hanging section 43111 and the matching portion 4322, thereby improving the reliability of the electrical device 3 being hung at the bottom of the vehicle body 2. In addition, the guide section 43112 can enable the insertion portion 4321 to accurately insert into the mounting section 43111 to improve the coordination efficiency between the insertion portion 4321 and the mounting section 43111, thereby further improving the installation efficiency of the electrical device 3 at the bottom of the vehicle body 2.

[0045] In the embodiment of the present application, there are many possible ways for the insertion portion 4321 to be inserted into the guide section 43112. For example, the end of the guide section 43112 facing away from the hanging section 43111 is an opening structure, and the insertion portion 4321 is inserted into the guide section 43112 through the opening structure. It should be noted that before the insertion portion 4321 is inserted into the guide section 43112, the height of the matching portion 4322 should be lower than the height of the guide section 43112 in the direction of gravity.

[0046] Reference Figure 6 In one possible implementation provided in the embodiment of the present application, the size of the guide section 43112 is larger than the outer diameter of the matching portion 4322, so that the matching portion 4322 can pass through the guide section 43112 along the direction of gravity. Since the outer diameter of the matching portion 4322 is larger than the outer diameter of the insertion portion 4321, and the size of the guide section 43112 is larger than the outer diameter of the matching portion 4322, the insertion portion 4321 can be inserted into the guide section 43112 along the direction of gravity without providing an opening structure on the end of the guide section 43112 facing away from the hanging section 43111, thereby improving the structural strength of the hanging hole, thereby increasing the reliability of the electrical device 3 when it is pre-hung on the bottom of the vehicle body 2.

[0047] In the embodiment of the present application, under the premise that the size of the guide section 43112 is larger than the outer diameter of the matching portion 4322, the shape of the guide section 43112 can be circular, long, or square, and the embodiment of the present application does not limit this. Figure 5 In one possible implementation provided in an embodiment of the present application, the guide section 43112 is circular in shape.

[0048] Reference Figure 3 and Figure 4 In the embodiment of the present application, the insertion portion 4321 is a movable stud, which is extended in the direction of gravity, and the matching portion 4322 is a matching nut, which is threadedly mounted on the movable stud. In this way, when the hanging portion 4311 and the matching portion 4322 are matched in the direction of gravity, the matching nut can be screwed so that the matching nut is pressed against the hanging portion 4311 in the direction of gravity to limit the movable space of the hanging portion 4311 in the direction of gravity, thereby further increasing the reliability of the electrical device 3 when it is pre-hung on the bottom of the vehicle body 2.

[0049] In the embodiment of the present application, the function of the pre-hanging component 43 is to pre-hang the second connecting member 42 on the electrical device 3 on the first connecting member 41 on the vehicle body 2. Therefore, the number of pre-hanging components 43 is possible in many ways. For example, the number of pre-hanging components 43 can be one group, two groups, or three groups, and the embodiment of the present application does not limit this. In addition, the function of the fixing component 44 is to fix the second connecting member 42 on the electrical device 3 and the first connecting member 41 on the vehicle body 2. Therefore, the number of fixing components 44 is also possible in many ways. For example, the number of fixing components 44 can be one group, two groups, or three groups, and the embodiment of the present application does not limit this.

[0050] In the embodiment of the present application, in the circumferential direction of the connecting assembly component 4, at least two groups of pre-hanging components 43 are provided, and at least two groups of fixing components 44 are provided. Each pre-hanging component 43 can form a pre-hanging point. Here, the pre-hanging component 43 is provided with at least two groups, which can increase the number of pre-hanging points between the first connecting member 41 and the second connecting member 42, thereby improving the reliability of the electrical device 3 when it is pre-hung on the bottom of the vehicle body 2. Each fixing component 44 can form a fixed point. Here, the fixing component 44 is provided with at least two groups, which can increase the number of fixed points between the first connecting member 41 and the second connecting member 42, thereby improving the reliability of the electrical device 3 when it is installed on the bottom of the vehicle body 2. Refer to Figure 2 In one possible implementation provided in the embodiment of the present application, the number of the pre-hanging components 43 and the number of the fixing components 44 are both two.

[0051] In the embodiment of the present application, when at least two groups of the fixing components 44 and the pre-hanging components 43 are provided on the circumference of the connecting assembly component 4, the arrangement positions of the fixing components 44 and the pre-hanging components 43 are possible in various ways. For example, on the circumference of the connecting assembly component 4, the fixing components 44 and the pre-hanging components 43 can be provided on different sides. Figure 2 In one possible implementation provided by the embodiment of the present application, at least two groups of fixing components 44 and at least two groups of pre-hanging components 43 are arranged alternately in sequence in the circumferential direction of the connecting assembly component 4. Here, the fixing components 44 and the pre-hanging components 43 are arranged alternately in sequence in the circumferential direction of the connecting assembly component 4, so that the pre-hanging point and the fixing point between the first connecting member 41 and the second connecting member 42 are arranged along the circumferential direction of the connecting assembly component 4, thereby simultaneously improving the reliability of the electrical device 3 when it is pre-hanged and fixed on the bottom of the vehicle body 2.

[0052] In the embodiment of the present application, the structural design of the first connecting member 41 and the second connecting member 42 has many possibilities. For example, the first connecting member 41 and the second connecting member 42 can be a block structure, a plate structure, or a frame structure, which is not limited in the embodiment of the present application. Figure 3 , Figure 4 and Figure 5 In one possible implementation provided in the embodiment of the present application, the first connector 41 and the second connector 42 are both plate-shaped structures. In this way, the space occupied by the first connector 41 and the second connector 42 in the gravity direction can be reduced, thereby reducing the space occupied by the electrical device 3 when it is installed at the bottom of the vehicle body 2.

[0053] In the embodiment of the present application, there is a connection plane between the first connector 41 and the second connector 42, the connection plane is a polygonal plane, at least two groups of pre-hanging components 43 are arranged at the connection plane, and at least two groups of pre-hanging components 43 include a first pre-hanging component 43a and a second pre-hanging component 43b, and the first pre-hanging component 43a and the second pre-hanging component 43b are arranged along the diagonal of the polygonal plane. Here, there is a connection plane between the first connector 41 and the second connector 42, and at least two groups of pre-hanging components 43 are arranged at the connection plane, which can reduce the gap between the first connector 41 and the second connector 42 in the direction of gravity, thereby further reducing the occupied space of the first connector 41 and the second connector 42 in the direction of gravity. The connecting plane is a polygonal plane, and at least two groups of pre-hanging components 43 include a first pre-hanging component 43a and a second pre-hanging component 43b. The first pre-hanging component 43a and the second pre-hanging component 43b are arranged along the diagonal of the polygonal plane. In this way, the stability and balance of the second connecting member 42 hung on the first connecting member 41 can be increased, the probability of slipping between the second connecting member 42 and the first connecting member 41 is reduced, and the safety of the installer during operation is improved.

[0054] In the embodiment of the present application, the connection plane refers to the plane where the contact surface of the first connection member 41 and the second connection member 42 is located. Therefore, the connection plane is a virtual plane. The shape of the connection plane has many possibilities. For example, the connection plane can be a rectangle, a pentagon, or a hexagon. The embodiment of the present application does not limit this. In an implementable manner provided in the embodiment of the present application, the connection plane is a rectangle. The first pre-hanging component 43a and the second pre-hanging component 43b are arranged along the diagonal of the rectangular plane.

[0055] In the embodiment of the present application, the positions of the first fixing member 441 and the second fixing member 442 can be interchanged. For example, the first fixing member 441 can be arranged on the first connecting member 41, and the second fixing member 442 can be arranged on the second connecting member 42; or, the second fixing member 442 can be arranged on the first connecting member 41, and the first fixing member 441 can be arranged on the second connecting member 42. The embodiment of the present application does not limit this. Figure 3 , Figure 4 and Figure 5 In one possible implementation provided in an embodiment of the present application, the first fixing member 441 is disposed on the second connecting member 42 , and the second fixing member 442 is disposed on the first connecting member 41 .

[0056] In the embodiment of the present application, the first fixing member 441 and the second fixing member 442 are used to fix the first connecting member 41 and the second connecting member 42. Therefore, there are many possibilities for the structural design of the first fixing member 441 and the second fixing member 442. For example, the first fixing member 441 has a first fixing portion, the second fixing member 442 has a second fixing portion, and the first fixing portion and the second fixing portion are fixedly matched along the gravity direction to fix the first connecting member 41 and the second connecting member 42. Alternatively, the first fixing member 441 has a first fixing portion, the second fixing member 442 has a second fixing portion, and the first fixing portion and the second fixing portion are fixedly matched along the horizontal direction to fix the first connecting member 41 and the second connecting member 42.

[0057] In the embodiment of the present application, there are many possible ways for the first fixing portion and the second fixing portion to cooperate. For example, the first fixing portion may be a clamping protrusion, and the second fixing portion may be a clamping slot. When the hanging portion 4311 and the matching portion 4322 are in a stopper cooperation along the gravity direction, the clamping protrusion and the clamping slot are aligned in the gravity direction, and the clamping protrusion and the clamping slot can be clamped and cooperated to complete the fixation between the first connecting member 41 and the second connecting member 42. Alternatively, the first fixing portion may be a first connecting hole, and the second fixing portion may include a second connecting hole and a fixing pin. When the hanging portion 4311 and the matching portion 4322 are in a stopper cooperation along the gravity direction, the first connecting hole and the second connecting hole are aligned in the horizontal direction, and the fixing pin passes through the first connecting hole and the second connecting hole in sequence to complete the fixation between the first connecting member 41 and the second connecting member 42.

[0058] Reference Figure 3 , Figure 4 and Figure 5 In one possible implementation provided in the embodiment of the present application, the first fixing portion is a fixing hole 4411, the second fixing portion includes a fixing stud 4421 and a fixing nut 4422, the fixing nut 4422 is threadedly mounted on the fixing stud 4421, the fixing hole 4411 and the hanging hole both extend in a preset direction, the fixing stud 4421 is extended in the direction of gravity, and when the insertion portion 4321 is inserted into the guide section 43112, the fixing stud 4421 can be inserted into the fixing hole 4411 synchronously, and in the preset direction, the moving distance of the fixing stud 4421 in the fixing hole 4411 is greater than or equal to the moving distance of the insertion portion 4321 from the guide section 43112 to the hanging section 43111. Here, the first fixing portion is a fixing hole 4411, and the second fixing portion includes a fixing stud 4421 and a fixing nut 4422. In this way, the first fixing portion and the second fixing portion have a relatively simple structure and are easy to process. When fixing the first connector 41 and the second connector 42, the fixing stud 4421 passes through the fixing hole 4411, and the fixing nut 4422 is threadedly installed on the fixing stud 4421 and pressed against the edge of the fixing hole 4411. Here, the fixing hole 4411 and the hanging hole both extend in a preset direction, and the fixing stud 4421 is extended in the direction of gravity. When the insertion portion 4321 is inserted into the guide section 43112, the fixing stud 4421 can be inserted into the fixing hole 4411 synchronously, and in the preset direction, the movable distance of the fixing stud 4421 in the fixing hole 4411 is greater than or equal to the distance of the insertion portion 4321 from the guide section 43112 to the hanging section 43111. In this way, when installing the electrical device 3, refer to Figure 6 First, move the second connecting member 42 along the gravity direction so that the extending portion 4321 extends into the guide section 43112 of the mounting hole. At this time, the fixing stud 4421 simultaneously extends into the fixing hole 4411. Next, refer to Figure 7 , move the second connecting member 42 along the preset direction, so that the insertion portion 4321 extends from the guide section 43112 into the hanging section 43111. During this process, the fixing stud 4421 moves synchronously in the fixing hole 4411. The moving distance of the fixing stud 4421 in the fixing hole 4411 is greater than or equal to the moving distance of the insertion portion 4321 from the guide section 43112 to the hanging section 43111. In this way, in the preset direction, it is possible to avoid the fixing stud 4421 abutting against the edge of the fixing hole 4411, which affects the insertion portion 4321 from extending into the hanging section 43111. Finally, referring to Figure 2 , threadably install the fixing nut 4422 on the fixing stud 4421 and press against the edge of the fixing hole 4411 to fix the first connecting member 41 and the second connecting member 42 .
