Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a vehicle body and a vehicle. Background Technology

[0002] With the advancement of technology and the improvement of people's living standards, vehicles are being used more and more widely. Vehicles typically contain many wiring harnesses and pipes to achieve the transmission of electrical signals and / or electrical energy, or the transfer of heat exchange media. However, the layout of wiring harnesses and pipes in vehicles is relatively complicated, and the routing of wires and pipes can easily affect vehicle assembly. Utility Model Content

[0003] This application proposes a vehicle body and a vehicle, wherein the connecting end can be used to connect the wiring harness and / or pipeline of the upper vehicle body, and the mating end can be used to connect the wiring harness and / or pipeline of the lower vehicle body, so that the wiring harness and pipeline arrangement in the vehicle body can be more orderly. At the same time, the connector can complete the transmission of electrical energy and / or electrical signals, or the flow of heat exchange medium between the upper and lower vehicle bodies, so as to meet the different needs of users for the vehicle body.

[0004] In a first aspect, embodiments of this application provide a vehicle body, including an upper vehicle body, a lower vehicle body, and at least one connector. The lower vehicle body is detachably connected to the upper vehicle body, and an abutment area is formed between the upper vehicle body and the lower vehicle body. The connector includes a connecting end and a mating end. The connecting end is fixed to the upper vehicle body, and the mating end is fixed to the lower vehicle body. The connecting end and the mating end are pluggable and detachable. The transmission of electrical energy and / or electrical signals between the upper vehicle body and the lower vehicle body is at least partially accomplished through the connector, and / or the transmission of heat exchange medium between the upper vehicle body and the lower vehicle body is at least partially accomplished through the connector.

[0005] In the above technical solution, the upper and lower vehicle bodies are detachably connected, meaning they are separate units. The connecting end is fixed to the upper vehicle body, and the mating end is fixed to the lower vehicle body. This allows the wiring harnesses and / or pipes of the upper vehicle body to be connected to the connecting end, and the wiring harnesses and / or pipes of the lower vehicle body to be connected to the mating end. Once the mating end and connecting end are assembled, the wiring harnesses and / or pipes of the upper vehicle body can be indirectly connected to the wiring harnesses and / or pipes of the lower vehicle body via connectors. This makes the wiring harnesses and pipes within the vehicle body more organized, and the wiring harnesses and / or pipes of the vehicle body less likely to interfere with the contact area between the upper and lower vehicle bodies, thus less likely to interfere with the assembly between the upper and lower vehicle bodies. At the same time, the connectors enable the transmission of electrical energy and / or electrical signals, and / or the flow of heat exchange media between the upper and lower vehicle bodies, facilitating the fulfillment of different user requirements for the vehicle body.

[0006] In some embodiments, the vehicle body further includes fasteners that detachably connect the upper vehicle body and the lower vehicle body and are located in the abutment area, wherein the upper vehicle body and the lower vehicle body are fixedly connected by the fasteners.

[0007] In the above technical solution, the upper body and the lower body are detachably fixed by fasteners, which makes it easier to disassemble and assemble the upper body and the lower body, and improves the maintenance efficiency of the vehicle body.

[0008] In some embodiments, the fasteners are bolts, studs, or screws; and / or, there are multiple fasteners spaced around the passenger compartment formed between the upper and lower vehicle bodies.

[0009] In the above technical solution, the fasteners are bolts, studs, or screws to make the assembly and disassembly of the upper and lower vehicle bodies more convenient, and to facilitate subsequent maintenance and repair; and / or, there are multiple fasteners to further improve the connection strength between the upper and lower vehicle bodies, and to improve the reliability of vehicle operation.

[0010] In some embodiments, the upper body includes at least one first wiring harness, the lower body includes at least one second wiring harness, the connector is an electrical connector, and at least one of the first wiring harnesses and at least one of the second wiring harnesses are electrically connected through the connector; and / or, the upper body includes at least one first conduit, the lower body includes at least one second conduit, the connector is a conduit connector, and at least one of the first conduits and at least one of the second conduits are connected through the connector.

[0011] In the above technical solutions, the electrical connector can connect the first wiring harness of the upper vehicle body and the second wiring harness of the lower vehicle body. Then, through the first wiring harness, the electrical connector and the second wiring harness, the transmission of electrical signals or electrical energy between the upper vehicle body and the lower vehicle body can be realized, which is beneficial to improving the reliability of the vehicle body; and / or, the pipe connector can connect the first pipe of the upper vehicle body and the second pipe of the lower vehicle body. Then, through the first pipe, the pipe connector and the second pipe, the transmission of heat exchange medium between the upper vehicle body and the lower vehicle body can be realized, which is beneficial to improving the reliability of the vehicle body.

[0012] In some embodiments, the connecting end has a first connector portion and the mating end has a second connector portion, the first connector portion and the second connector portion are quick-connected; and / or, the first connector portion and the second connector portion are quick-released.

[0013] In the above technical solution, the first connector and the second connector are quick-connected, meaning that the assembly of the first connector and the second connector can be achieved without the use of tools, thereby realizing the assembly of the connecting end and the mating end, making the assembly of the connecting end and the mating end more convenient and improving the assembly efficiency of the vehicle body; and / or, the first connector and the second connector are quick-released, meaning that the separation of the first connector and the second connector can be achieved without the use of tools, thereby realizing the separation of the connecting end and the mating end, making the separation of the connecting end and the mating end more convenient and improving the disassembly efficiency of the vehicle body.

[0014] In some embodiments, the connecting end and the mating end are plugged in and plugged in along the vertical direction of the vehicle.

[0015] In the above technical solution, the insertion and removal directions of the connecting end and the mating end are consistent with the assembly direction of the vehicle body, so that the assembly and disassembly of the connecting end and the mating end can be more convenient. At the same time, the connection between the connecting end and the mating end is more stable due to the gravity of the upper vehicle body and the force of the fasteners. There is no need to use an additional locking mechanism to lock the connector, which can improve the assembly and disassembly efficiency of the vehicle body and also help improve the stability of the vehicle body during operation.

[0016] In some embodiments, the upper vehicle body has at least one first positioning part, and the lower vehicle body has at least one second positioning part, wherein the first positioning part and the corresponding second positioning part are inserted into each other and positioned in a matching manner.

[0017] In the above technical solution, the first positioning part and the corresponding second positioning part are positioned and cooperated, which makes it easier to reduce the assembly difficulty of the upper body and the lower body. At the same time, after the upper body and the lower body are assembled, the connecting end and the mating end are also assembled, which makes it easier to further improve the assembly efficiency of the vehicle body.

[0018] In some embodiments, the connector further includes a first sealing member that seals between the connecting end and the mating end and is disposed around the connector's pins or communication channels; and / or, an occupant compartment is formed between the upper body and the lower body, and the vehicle body further includes a second sealing member that seals between the upper body and the lower body and is located around the occupant compartment, with the connector located on the side of the second sealing member adjacent to the occupant compartment.

[0019] In the above technical solution, the first sealing component is arranged around the connector pin, and the first sealing component can prevent external impurities from entering the connector, which facilitates the improvement of the reliability of the connector operation; and / or, the connector is located between the second component and the crew compartment, and the second sealing component can prevent external impurities from entering the connector, which facilitates the improvement of the reliability of the connector operation.

[0020] In some embodiments, a second sealing member is disposed around the passenger compartment.

[0021] In the above technical solution, the second sealing component is arranged around the passenger compartment, and the connector is located between the second sealing component and the passenger compartment, so as to make the installation position of the connector more flexible.

[0022] In some embodiments, the abutment area is disposed around the passenger compartment and located on the side of the second sealing member adjacent to the passenger compartment, and the connector is located between the second sealing member and the abutment area.

[0023] In the above technical solution, the abutment area is located inside the second sealing component. The abutment area can be used to support the upper vehicle body so that the force exerted by the upper vehicle body on the second sealing component is not too large, thereby improving the service life of the second sealing component.

[0024] In some embodiments, an upper body and a lower body are enclosed to form a passenger compartment and a front compartment. The upper body includes a front bulkhead disposed between the passenger compartment and the front compartment, and a connecting end is fixed to the lower end of the front bulkhead. The lower body includes a crossbeam disposed below the front bulkhead, and a mating end is fixed to the crossbeam. At least a portion of the second sealing member and / or the first sealing member are sandwiched between the front bulkhead and the crossbeam.

[0025] In the above technical solution, at least a portion of the second sealing component and / or the first sealing component are sandwiched between the front bulkhead and the crossbeam. After the connecting end and the mating end are assembled, the second sealing component and / or the first sealing component can prevent external impurities from entering the connector, which facilitates improving the sealing level of the connector and makes the setting position of the connector more flexible.

[0026] In some embodiments, the connector is offset from the center of the beam along its length.

[0027] In the above technical solution, the connector is offset from the center position of the crossbeam in its length direction, so that the center position of the crossbeam can also be used to arrange other components, which helps to reduce the possibility of interference between the connector and other components.

[0028] In some embodiments, the front bulkhead includes a first wall and a second wall. The first wall is horizontally disposed and has a first mounting hole. A connecting end is disposed at the first mounting hole. The second wall is bent and connected to the end of the first wall away from the passenger compartment, and defines a first cavity with the first wall for receiving the connecting end. The crossbeam includes a third wall and a fourth wall. The third wall is parallel to the first wall and has a second mounting hole. A mating end is disposed at the second mounting hole. The fourth wall is bent and connected to the end of the third wall away from the passenger compartment, and defines a second cavity with the third wall for receiving the mating end.

[0029] In the above technical solution, the structure of the front bulkhead and the crossbeam is relatively simple, which facilitates the improvement of the processing efficiency of the front bulkhead and the crossbeam. In addition, the third wall and the first wall are parallel, which makes the assembly of the connecting end and the mating end simpler.

[0030] In some embodiments, the connecting end includes a first base, a first terminal, and a first mounting base. The first terminal is disposed on the first base, and the first mounting base is disposed on the outer peripheral wall of the first base and surrounds the first base. The first mounting base is connected to the side of the first wall opposite to the third wall. And / or, the mating end includes a second base, a second terminal, and a second mounting base. The second terminal is disposed on the second base and is adapted to be electrically connected to the first terminal of the connecting end. The second mounting base is disposed on the outer peripheral wall of the second base and surrounds the second base. The second mounting base is connected to the side of the third wall opposite to the first wall.

[0031] In the above technical solution, the first mounting base is connected to the side of the first wall away from the third wall in order to reduce the protrusion height of the first base. The second mounting base is connected to the side of the third wall away from the first wall in order to reduce the protrusion height of the second base. Through the above-mentioned arrangement of the first mounting base and the second mounting base, the gap between the first wall and the third wall will not be too large after the connecting end and the mating end are assembled, so as to make the structure of the vehicle body more compact.

[0032] In some embodiments, a first reinforcing structure is provided on the first wall, the first reinforcing structure being disposed adjacent to the first mounting hole; and / or, a second reinforcing structure is provided on the third wall, the second reinforcing structure being disposed adjacent to the second mounting hole.

[0033] In the above technical solution, the first reinforcing structure is disposed adjacent to the first mounting hole to give the first mounting hole better structural strength and facilitate the improvement of the service life of the first mounting hole; and / or, the second reinforcing structure is disposed adjacent to the second mounting hole to give the second mounting hole better structural strength and facilitate the improvement of the service life of the second mounting hole.

[0034] Secondly, embodiments of this application provide a vehicle, including the vehicle body of the first aspect.

[0035] In the above technical solution, since the assembly of the vehicle body is relatively convenient, the use of this vehicle body can improve the assembly efficiency of the vehicle. Attached Figure Description

The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

For example, they can refer to direct connection or indirect connection through an intermediate medium.

[0052] In the embodiments of this application, the same reference numerals denote the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments. It should be understood that the dimensions of the various components shown in the accompanying drawings in the embodiments of this application are merely illustrative and should not constitute any limitation on this application.

[0053] In this application, "multiple" means two or more (including two).

[0054] With the advancement of technology and the improvement of people's living standards, vehicles are being used more and more widely. Vehicle bodies typically contain many wiring harnesses and pipes to realize the transmission of electrical signals and / or electrical energy, or the transfer of heat exchange media. However, the arrangement of wiring harnesses and pipes in the vehicle body is relatively complicated, and the routing of wires and pipes can easily affect vehicle assembly.

[0055] Based on the above considerations, this application proposes a vehicle body, which includes an upper vehicle body, a lower vehicle body, and at least one connector. The lower vehicle body is detachably connected to the upper vehicle body, and an abutment area is formed between the upper vehicle body and the lower vehicle body. The connector includes a connecting end and a mating end. The connecting end is fixed to the upper vehicle body, and the mating end is fixed to the lower vehicle body. The connecting end and the mating end are pluggable and detachable. The transmission of electrical energy and / or electrical signals between the upper vehicle body and the lower vehicle body is at least partially accomplished through the connector, and / or the transmission of heat exchange medium between the upper vehicle body and the lower vehicle body is at least partially accomplished through the connector.

[0056] In the above technical solution, the upper and lower vehicle bodies are detachably connected, meaning they are separate units. The connecting end is fixed to the upper vehicle body, and the mating end is fixed to the lower vehicle body. This allows the wiring harnesses and / or pipes of the upper vehicle body to be connected to the connecting end, and the wiring harnesses and / or pipes of the lower vehicle body to be connected to the mating end. Once the mating end and connecting end are assembled, the wiring harnesses and / or pipes of the upper vehicle body can be indirectly connected to the wiring harnesses and / or pipes of the lower vehicle body via connectors. This makes the wiring harnesses and pipes of the vehicle body more organized, and the wiring harnesses and / or pipes of the vehicle body less likely to interfere with the contact area between the upper and lower vehicle bodies, thus less likely to interfere with the assembly between the upper and lower vehicle bodies. At the same time, the connectors enable the transmission of electrical energy and / or electrical signals, and / or the flow of heat exchange media between the upper and lower vehicle bodies, facilitating the fulfillment of different user requirements for the vehicle body.

[0057] Please refer to Figures 1-3 In the embodiments of this application, the vehicle body 1 includes: an upper vehicle body 10, a lower vehicle body 20, and at least one connector 40. The lower vehicle body 20 is detachably connected to the upper vehicle body 10, so the upper vehicle body 10 and the lower vehicle body 20 are separately arranged. An abutment area 12 is formed between the upper vehicle body 10 and the lower vehicle body 20. The connector 40 includes a connecting end 41 and a mating end 42. The connecting end 41 is fixed to the upper vehicle body 10, and the mating end 42 is fixed to the lower vehicle body 20. The connecting end 41 and the mating end 42 are pluggable and detachable. The transmission of electrical energy and / or electrical signals between the upper vehicle body 10 and the lower vehicle body 20 is at least partially completed through the connector 40, and / or the transmission of heat exchange medium between the upper vehicle body 10 and the lower vehicle body 20 is at least partially completed through the connector 40.

[0058] It is understood that this application does not limit the assembly direction and disassembly direction of the upper vehicle body 10 and the lower vehicle body 20. For example, the upper vehicle body 10 and the lower vehicle body 20 can be assembled and decoupled along the vertical direction of the vehicle 2, or the upper vehicle body 10 and the lower vehicle body 20 can be assembled and decoupled in the horizontal direction, or the upper vehicle body 10 and the lower vehicle body 20 can be assembled and decoupled in the direction that is inclined to the vertical direction and the horizontal direction, respectively.

[0059] For example, vehicle body 1 can refer to the vehicle body 1 of a skateboard chassis vehicle, which has a lower body 20 with the shape of a skateboard, that is, the lower body 20 refers to the skateboard chassis; the vehicle model corresponding to vehicle body 1 is not limited to this. Regardless of the vehicle model, the upper body 10 and the lower body 20 can be set separately, and the upper body 10 and the lower body 20 can be detachably connected so that the upper body 10 and the lower body 20 can be replaced according to actual needs, which can improve the flexibility of vehicle body 1.

[0060] For example, when connector 40 is an electrical connector, connection end 41 can refer to one of the male and female ends of connector 40, and mating end 42 refers to the other of the male and female ends of connector 40. The male and female ends can be inserted in the vertical direction to achieve the connection between the male and female ends. At this time, connector 40 can realize the transmission of electrical signals and / or electrical energy between the upper vehicle body 10 and the lower vehicle body 20. Of course, connector 40 can also be of other types. For example, connector 40 is a pipeline connector. Pipeline connector can include a first mating end and a second mating end that are inserted and mated. Connection end 41 can refer to one of the first mating end and the second mating end, and mating end 42 refers to the other of the first mating end and the second mating end. At this time, connector 40 can realize the transmission of heat exchange medium between the upper vehicle body 10 and the lower vehicle body 20.

[0061] As can be seen, the upper body 10 is detachably connected to the lower body 20, thus the upper body 10 and the lower body 20 are separately configured, making the vehicle body 1 a split-type vehicle body. The upper body 10 and the lower body 20 can be independently configured, facilitating subsequent maintenance or replacement of at least one of the upper body 10 and the lower body 20, improving the maintenance efficiency of the vehicle body 1. Furthermore, the separation and decoupling of the upper body 10 and the lower body 20 allows for replacement of the upper body 10 as needed, shortening the development cycle and reducing costs. It is understood that this application does not limit the detachable connection method of the upper body 10 and the lower body 20. For example, the upper body 10 and the lower body 20 can be detachably connected by fasteners, or the upper body 10 and the lower body 20 can be quickly connected and disassembled manually using devices such as quick clamps, clips, or spring clips, or the upper body 10 and the lower body 20 can be detachably connected by the cooperation of pins and holes, etc.

[0062] In addition, the connecting end 41 is fixed to the upper body 10 and the mating end 42 is fixed to the lower body 20. When the connector 40 needs to be repaired, the upper body 10 and the lower body 20 are separated so that the staff can more easily observe and access the connecting end 41 and the mating end 42. The split-type body 1 can provide a larger repair space for the connector 40 and facilitate the improvement of the maintenance efficiency of the connector 40.

[0063] It is understood that this application does not restrict the insertion and removal direction of the connecting end 41 and the mating end 42. For example, the connecting end 41 and the mating end 42 can be inserted and removed along the vertical direction of the vehicle 2, or the connecting end 41 and the mating end 42 can be inserted and removed in the horizontal direction, or the connecting end 41 and the mating end 42 can be inserted and removed in directions that are inclined to the vertical and horizontal directions respectively.

[0064] For example, the upper body 10 and the lower body 20 are detachably connected along the vertical direction of the vehicle 2. The insertion and removal directions of the connecting end 41 and the mating end 42 can be consistent with the overall disassembly and assembly direction (vertical direction) of the upper body 10 and the lower body 20, or they can be at a certain angle to the overall disassembly and assembly direction of the upper body 10 and the lower body 20. For example, the entire lower body 20 is located below the upper body 10, in which case the connecting end 41 and the mating end 42 can be inserted and removed along the vertical direction of the vehicle 2; or, for another example, a part of the lower body 20 is located below the upper body 10, and another part of the lower body 20 is located on the outer periphery of the upper body 10 (for example, a part of the lower body 20 is located on at least one of the left, right, front, and rear sides of the upper body 10), in which case the connecting end 41 and the mating end 42 can be inserted and removed along the horizontal direction or in a direction inclined to the relative horizontal direction.

[0065] Specifically, the transmission of electrical energy and / or electrical signals between the upper vehicle body 10 and the lower vehicle body 20 is at least partially accomplished through connector 40, and / or the transmission of heat exchange medium between the vehicle body 10 and the lower vehicle body 20 is at least partially accomplished through connector 40. For example, when connector 40 is an electrical connector, connector 40 can connect the wiring harness of the upper vehicle body 10 (e.g., the first wiring harness described later) and the wiring harness of the lower vehicle body 20 (e.g., the second wiring harness described later), providing a clear wiring location for the wiring harness of the upper vehicle body 10 and the lower vehicle body 20 (e.g., the wiring harness connection terminal 41 of the upper vehicle body 10 and the wiring harness connection mating terminal 42 of the lower vehicle body 20), making the wiring path of the wiring harness in the vehicle body 1 clearer, facilitating the simplification and organization of the wiring harness arrangement in the vehicle body 1, while the upper vehicle body 10's... The wiring harnesses of the upper body 10 and the lower body 20 can be indirectly connected via connector 40, so that the contact area 12 between the upper body 10 and the lower body 20 avoids interference with the wiring harnesses of both the upper body 10 and the lower body 20. Connector 40 can thus provide some protection for the wiring harnesses of the vehicle body 1, preventing interference between the wiring harnesses of the upper body 10 and the lower body 20 during their assembly. This allows the electrical connector to transmit electrical energy and / or signals more stably between the upper body 10 and the lower body 20, thereby improving the reliability of the vehicle body 1. For example, when connector 40 is a pipe connector, connector 40 can connect the pipes of the upper body 10 (e.g., the first pipe described later) and the pipes of the lower body 20 (e.g., the second pipe described later), providing a clear pipe routing location for the pipes of the upper body 10 and the lower body 20 (e.g., the pipe connection end 41 of the upper body 10 and the pipe connection mating end 42 of the lower body 20), making the pipe routing path within the vehicle body 1 clearer, facilitating the simplification and organization of the pipe layout within the vehicle body 1, while the upper body 1 The pipes of the upper body 10 and the lower body 20 can be indirectly connected through the connector 40 so that the contact area 12 between the upper body 10 and the lower body 20 avoids the pipes of the upper body 10 and the lower body 20. The connector 40 can play a certain role in protecting the pipes of the vehicle body 1 so that the pipes of the upper body 10 and the lower body 20 are less likely to interfere with the assembly process of the upper body 10 and the lower body 20. This allows the electrical connector to transfer the heat exchange medium more stably between the upper body 10 and the lower body 20, thereby improving the reliability of the vehicle body 1.

[0066] It is understood that the transmission of electrical energy and / or electrical signals between the upper vehicle body 10 and the lower vehicle body 20 is at least partially accomplished through the connector 40, including: Example 1, where a portion of the transmission of electrical energy and / or electrical signals between the upper vehicle body 10 and the lower vehicle body 20 is accomplished through the connector 40, and the other portion is accomplished through other means; Example 2, where the transmission of electrical energy and / or electrical signals between the upper vehicle body 10 and the lower vehicle body 20 is entirely accomplished through the connector 40. In Examples 1 and 2 above, the connector 40 can be an electrical connector, and the number can be one or more.

[0067] The transfer of the heat exchange medium between the upper body 10 and the lower body 20 is at least partially accomplished through the connector 40, including: Example 3, where a portion of the transfer of the heat exchange medium between the upper body 10 and the lower body 20 is accomplished through the connector 40, and the other portion is accomplished through other means; Example 4, where the transfer of the heat exchange medium between the upper body 10 and the lower body 20 is entirely accomplished through the connector 40. In Examples 3 and 4 above, the connector 40 can be a pipe connector, and the number can be one or more.

[0068] The transmission of electrical energy and / or electrical signals between the upper vehicle body 10 and the lower vehicle body 20 is at least partially accomplished through connector 40, and / or the transmission of heat exchange medium between the upper vehicle body 10 and the lower vehicle body 20 is at least partially accomplished through connector 40, including: Embodiment 1, the transmission of electrical energy and / or electrical signals between the upper vehicle body 10 and the lower vehicle body 20 is entirely accomplished through connector 40, and the transmission of heat exchange medium between the upper vehicle body 10 and the lower vehicle body 20 is entirely accomplished through connector 40 (i.e., a combination of Examples 2 and 4 above); Embodiment 2, the transmission of electrical energy and / or electrical signals between the upper vehicle body 10 and the lower vehicle body 20 is entirely accomplished through connector 40. Part of the transmission of the signal is completed through connector 40, and part of the transmission of the heat exchange medium between the upper body 10 and the lower body 20 can also be completed through connector 40 (i.e., a combination of Examples 1 and 3 above); Example 3: All transmission of electrical energy and / or electrical signals between the upper body 10 and the lower body 20 is completed through connector 40, and part of the transmission of the heat exchange medium between the upper body 10 and the lower body 20 is completed through connector 40 (i.e., a combination of Examples 2 and 3 above); Example 4: Part of the transmission of electrical energy and / or electrical signals between the upper body 10 and the lower body 20 is completed through... In Example 5, a portion of the transmission of electrical energy and / or electrical signals between the upper vehicle body 10 and the lower vehicle body 20 is completed through connector 40, while the transmission of the heat exchange medium between the upper vehicle body 10 and the lower vehicle body 20 is not completed through connector 40 but through other means; in Example 6, the transmission of electrical energy and / or electrical signals between the upper vehicle body 10 and the lower vehicle body 20 is completed entirely through connector 40, while the transmission of the heat exchange medium between the upper vehicle body 10 and the lower vehicle body 20 is not completed through connector 40 but through other means. The transmission of the medium is not completed through connector 40, but is achieved through other means; in embodiment seven, a portion of the transmission of the heat exchange medium between the upper body 10 and the lower body 20 is completed through connector 40, and the transmission of electrical energy and / or electrical signals between the upper body 10 and the lower body 20 is not completed through connector 40, but is achieved through other means; in embodiment eight, the transmission of the heat exchange medium between the upper body 10 and the lower body 20 is entirely completed through connector 40, and the transmission of electrical energy and / or electrical signals between the upper body 10 and the lower body 20 is not completed through connector 40, but is achieved through other means.

[0069] In each of the above embodiments one to four, there are multiple connectors 40, including at least one electrical connector and at least one conduit connector; in each of the above embodiments five to eight, there is at least one connector 40.

[0070] Moreover, the aforementioned connector 40 can meet the different usage needs of users for the vehicle body 1.

[0071] For example, the upper body 10 includes an upper body and a smart cockpit, etc. The interior of the upper body can be used to house the smart cockpit so that when the user is in the smart cockpit, the upper body can provide a certain degree of protection for the user. The connecting end 41 is fixed to the upper body 10. The lower body 20 includes a lower body, a thermal management system, a suspension system, a braking system, a steering system, and a power system, etc. For example, the lower body is a skateboard chassis. The thermal management system, suspension system, braking system, steering system, and power system are all installed in the lower body. The mating end 42 is fixed to the lower body 20. After the connection end 41 and mating end 42 are assembled, the connector 40 can stably transmit electrical signals, electrical energy or heat exchange medium between the upper vehicle body 10 and the lower vehicle body 20. For example, when the connector 40 is an electrical connector, it can transmit electrical signals or electrical energy between the upper vehicle body 10 and the lower vehicle body 20, so that the user located in the upper vehicle body 10 can control the thermal management system, suspension system, braking system, steering system and power system of the lower vehicle body 20 as needed, so as to meet the user's operation needs (for example, when the vehicle body 1 is used for the vehicle 2, controlling the steering, braking and acceleration of the vehicle 2). When the connector 40 is a pipeline connector, it can transmit the heat exchange medium between the upper vehicle body 10 and the lower vehicle body 20, so that the user located in the vehicle body 10 can control the thermal management system of the lower vehicle body 20 as needed (for example, including at least one of the engine cooling system, battery cooling system, air conditioning system, etc.), so as to meet the user's different usage needs (for example, by meeting the user's cooling or heating needs for the vehicle body).

[0072] It is understood that in this embodiment, the number of connectors 40 is not specifically limited, and there can be one or more connectors 40. When there is a single connector 40, it can be an electrical connector or a pipe connector. When there are multiple connectors 40, the types of the multiple connectors 40 can be the same or different. For example, all connectors 40 can be electrical connectors, or all connectors 40 can be pipe connectors, or at least one of the multiple connectors 40 can be an electrical connector and at least one of the remaining connectors 40 can be a pipe connector. That is, some connectors 40 can be used for the transmission of electrical energy and / or electrical signals between the upper vehicle body 10 and the lower vehicle body 20, and at least one of the remaining connectors 40 can be used for the transmission of heat exchange medium between the upper vehicle body 10 and the lower vehicle body 20.

[0073] In some embodiments, the vehicle body 1 further includes fasteners that detachably connect the upper vehicle body 10 and the lower vehicle body 20. The upper vehicle body 10 and the lower vehicle body 20 are fixedly connected by the fasteners, allowing for detachable fixing. Separating the fasteners allows for separation of the upper vehicle body 10 and the lower vehicle body 20, while locking the fasteners allows for fixing. This improves the efficiency of disassembly and assembly of the upper vehicle body 10 and the lower vehicle body 20, and facilitates subsequent maintenance of the vehicle body 1. The fasteners are located in the abutment area 12 to apply a locking force to the upper vehicle body 10 and the lower vehicle body 20.

[0074] In some embodiments, the fasteners are bolts, studs, or screws; and / or, there are multiple fasteners spaced around the passenger compartment 62 formed between the upper body 10 and the lower body 20.

[0075] As can be seen, the fasteners are bolts, studs, or screws, which make the assembly and disassembly of the upper body 10 and the lower body 20 more convenient, facilitating subsequent maintenance and repair. At the same time, the fasteners can provide good connection strength and stability, making the connection between the upper body 10 and the lower body 20 more stable, effectively resisting various vibrations and impacts generated during the operation of the vehicle body 1, and ensuring the integrity and stability of the vehicle body 1 structure; and / or, there are multiple fasteners, and the multiple fasteners work together to fix the upper body 10 and the lower body 20, which can further improve the connection strength between the upper body 10 and the lower body 20, and facilitate improving the reliability of the vehicle body 1 operation.

[0076] In some embodiments, the upper vehicle body 10 includes at least one first wiring harness, the lower vehicle body 20 includes at least one second wiring harness, and the connector 40 is an electrical connector. At least one of the first wiring harnesses and at least one of the second wiring harnesses are electrically connected through the connector 40 to transmit electrical energy and / or electrical signals between the upper vehicle body 10 and the lower vehicle body 20; and / or, the upper vehicle body 10 includes at least one first conduit, the lower vehicle body 20 includes at least one second conduit, and the connector 40 is a conduit connector. At least one of the first conduits and at least one of the second conduits are connected through the connector 40 to allow heat exchange medium to flow between the upper vehicle body 10 and the lower vehicle body 20.

[0077] As can be seen, the electrical connector is used to electrically connect the first wiring harness located on the upper vehicle body 10 and the second wiring harness located on the lower vehicle body 20. For example, the connecting end 41 is connected to the first wiring harness on the upper vehicle body 10, and the mating end 42 is connected to the second wiring harness on the lower vehicle body 20. After the connecting end 41 and the mating end 42 are assembled, the first wiring harness and the second wiring harness can be used as signal lines or power supply lines so that the first wiring harness and the second wiring harness can be used to transmit electrical signals or electrical energy. Then, the transmission of electrical signals or electrical energy between the upper vehicle body 10 and the lower vehicle body 20 can be completed through the first wiring harness, the electrical connector and the second wiring harness. For example, when the vehicle body 1 includes a safety system, the accurate transmission of electrical signals or electrical energy can be achieved through the first wiring harness, the electrical connector and the second wiring harness, which helps the safety system of the vehicle 2 (such as ABS, ESP, etc.) to work normally and improves the reliability of the vehicle 2. The pipe connector is used to connect the first pipe located on the upper body 10 and the second pipe located on the lower body 20. The pipe connector is suitable for the flow of heat exchange medium. For example, the connecting end 41 is connected to the first pipe of the upper body 10, and the mating end 42 is connected to the second pipe of the lower body 20. The pipe connector has a connecting channel connecting the first pipe and the second pipe. When the connecting end 41 and the mating end 42 are assembled, the first pipe and the second pipe can be used to transfer the heat exchange medium. The heat exchange medium (e.g., coolant, refrigerant, etc.) can be transferred efficiently through the first pipe, the pipe connector, and the second pipe. When the vehicle body 1 includes a thermal management system, the heat exchange medium can be transferred stably through the first pipe, the pipe connector, and the second pipe so that the thermal management system of the vehicle 2 (e.g., including at least one of the engine cooling system, battery cooling system, air conditioning system, etc.) can work normally and provide a suitable operating environment for the vehicle 2.

[0078] It is understood that, regardless of the number of first wiring harnesses in the upper body 10 or the number of second wiring harnesses in the lower body 20, at least one of the first wiring harnesses in the upper body 10 and at least one of the second wiring harnesses in the lower body 20 are electrically connected to each other through at least one connector 40; similarly, regardless of the number of first conduits in the upper body 10 or the number of second conduits in the lower body 20, at least one of the first conduits in the upper body 10 and at least one of the second conduits in the lower body 20 are electrically connected to each other through at least one connector 40.

[0079] For example, connector 40 is an electrical connector. The upper body 10 includes multiple first wire harnesses, and the lower body 20 includes multiple second wire harnesses. All first wire harnesses and all second wire harnesses are connected through one connector 40, or all first wire harnesses and all second wire harnesses are respectively connected through multiple connectors 40, or a portion of the first wire harnesses and a portion of the second wire harnesses are connected through at least one connector 40, while another portion of the first wire harnesses and another portion of the second wire harnesses are connected through other components. As another example, connector 40 is a conduit connector. The upper body 10 includes multiple first conduits, and the lower body 20 includes multiple second conduits. All first conduits and all second conduits are connected through one connector 40, or all first conduits and all second conduits are respectively connected through multiple connectors 40, or a portion of the first conduits and a portion of the second conduits are connected through at least one connector 40, while another portion of the first conduits and another portion of the second conduits are connected through other components.

[0080] Optionally, both the first and second wiring harnesses in this application are standardized wiring harnesses. A standardized wiring harness refers to a cable assembly designed, manufactured, and tested according to unified standards. It can be used to efficiently and reliably transmit electrical signals or power, ensuring good compatibility, reliability, and replaceability for both the first and second wiring harnesses. This facilitates the standardized design and modular application of wiring harnesses within the vehicle body 1, and facilitates the rapid installation, maintenance, and upgrade of both the first and second wiring harnesses. Similarly, both the first and second conduits in this application are standardized conduits. A standardized conduit refers to a piping system designed according to unified specifications, dimensions, materials, and connection methods. This ensures interchangeability and compatibility between different equipment or systems, and can be used to stably transmit heat exchange media. This ensures good compatibility, reliability, and replaceability for both the first and second conduits, facilitating the standardized design and modular application of conduits within the vehicle body 1. This also facilitates the maintenance of both the first and second conduits. For example, if a section of conduit leaks, a standardized conduit of the same specification can be directly replaced, enabling rapid replacement of standardized conduits and reducing downtime.

[0081] In some embodiments, when connector 40 is an electrical connector, all wiring harnesses of the upper vehicle body 10 are electrically connected to all wiring harnesses of the lower vehicle body 20 through one electrical connector, or all wiring harnesses of the upper vehicle body 10 are electrically connected to all wiring harnesses of the lower vehicle body 20 through multiple electrical connectors respectively. After the connecting end 41 and mating end 42 are assembled, all wiring harnesses between the upper vehicle body 10 and the lower vehicle body 20 can be connected through connector 40 to complete the electrical connection of all wiring harnesses between the upper vehicle body 10 and the lower vehicle body 20. After the connecting end 41 and mating end 42 are separated, all wiring harnesses of the upper vehicle body 10 and the lower vehicle body 20 can be separated, so that the assembly and disassembly of the upper vehicle body 10 and the lower vehicle body 20 are less affected by the wiring harnesses, thus improving the assembly and disassembly efficiency of the vehicle body 1. Rate; and / or, when connector 40 is a pipe connector, all pipes of the upper vehicle body 10 are connected to all pipes of the lower vehicle body 20 through one pipe connector, or, all pipes of the upper vehicle body 10 are connected to all pipes of the lower vehicle body 20 respectively through multiple pipe connectors. Then, after the connection end 41 and the mating end 42 are assembled, all pipes between the upper vehicle body 10 and the lower vehicle body 20 can be connected through connector 40 to complete the heat exchange medium transfer between the upper vehicle body 10 and the lower vehicle body 20. After the connection end 41 and the mating end 42 are separated, all pipes between the upper vehicle body 10 and the lower vehicle body 20 can be separated so that the assembly and disassembly of the upper vehicle body 10 and the lower vehicle body 20 are not easily affected by the pipes, which facilitates the improvement of the assembly efficiency and disassembly efficiency of the vehicle body 1.

[0082] In some embodiments, the connecting end 41 has a first connector portion and the mating end 42 has a second connector portion. The first connector portion and the second connector portion are quick-connected; and / or, the first connector portion and the second connector portion are quick-released.

[0083] As can be seen, the first connector and the second connector are quick-connect fitting, which means that the first connector and the second connector can be inserted and mated without the use of tools, thereby realizing the assembly of the connecting end 41 and the mating end 42, making the assembly of the connecting end 41 and the mating end 42 more convenient and improving the assembly efficiency of the vehicle body 1; and / or, the first connector and the second connector are quick-release fitting, which means that the first connector and the second connector can be separated without the use of tools, thereby realizing the separation of the connecting end 41 and the mating end 42, making the separation of the connecting end 41 and the mating end 42 more convenient and improving the disassembly efficiency of the vehicle body 1.

[0084] Therefore, quick insertion and quick removal can be achieved through the first connector and the second connector. For example, both the first connector and the second connector are quick-change connectors, which facilitates quick insertion and quick removal of the connector 40, thereby improving the assembly and disassembly efficiency of the vehicle body 1.

[0085] For example, taking connector 40 as an electrical connector: the connecting end 41 includes a first base 410 and a first terminal 411. The first terminal 411 is disposed on the first base 410, and the first base 410 surrounds the first terminal 411. In the vertical direction, the first base 410 protrudes downward from the lower end of the first terminal 411. The mating end 42 includes a second base 420 and a second terminal 421. The second terminal 421 is disposed on the second base 420, and the second base 410 surrounds the second terminal 421. In configuration 21, a radial distance is provided between the second base 420 and the second terminal 421 to define an annular slot between them. The first base 420 is inserted into the slot in the vertical direction to achieve a quick-connect engagement between the connecting end 41 and the mating end 42. When the connecting end 41 and the mating end 42 are separated, the first base 420 is lifted upwards to disengage from the slot, thus achieving a quick-connect engagement between the connecting end 41 and the mating end 42. Therefore, the first base 410 can be understood as the first connector, and the slot can be understood as the second connector. Of course, the structure of the first connector and the second connector is not limited to this; any configuration that allows for quick insertion and removal of the connecting end 41 and the mating end 42 without the need for tools is acceptable.

[0086] Please refer to Figure 1 and Figure 2 In some embodiments, the connecting end and the mating end are plugged in and plugged in along the vertical direction of the vehicle.

[0087] As can be seen, the upper body 10 and the lower body 20 are detachably connected. The connecting end 41 is fixed to the upper body 10, and the mating end 42 is fixed to the lower body 20. The connecting end 41 and the mating end 42 can be connected along the vertical direction (e.g., Figure 1When the connector is plugged in (AA' direction), the assembly direction of the connecting end 41 and the mating end 42 is consistent with the assembly direction of the upper body 10 and the lower body 20. When the upper body 10 and the lower body 20 are assembled, the connecting end 41 and the mating end 42 can also be assembled; when the upper body 10 and the lower body 20 are separated, the connecting end 41 and the mating end 42 can also be separated. Fasteners can be used to lock and fix the upper body 10 and the lower body 20, and to a certain extent, the fasteners can also lock the connecting end 41 and the mating end 42. At the same time, the gravity direction of the upper body 10 is consistent with the assembly direction of the connector 40, allowing the connector 40 to maintain a stable connection without the need for additional... The external locking mechanism locks the connector 40, making the assembly and disassembly of the vehicle body 1 simpler and improving the assembly and disassembly efficiency of the vehicle body 1. When the connector 40 needs maintenance, the connecting end 41 and mating end 42 can be separated by separating the upper vehicle body 10 and the lower vehicle body 20, making the separation operation of the connector 40 simpler and improving the maintenance efficiency of the connector 40. At the same time, the separation of the upper vehicle body 10 and the lower vehicle body 20 provides more operating space for the staff, allowing them to better access the connector 40. There is no need to reserve operating space for the connector 40 inside the vehicle body 1, so that the structure of the vehicle body 1 can be compact and facilitate the arrangement of other components.

[0088] Furthermore, the fasteners detachably connect the upper body 10 and the lower body 20. After assembly, the upper body 10 and the lower body 20 can be locked together by the fasteners, making the assembly of the upper body 10 and the lower body 20 more stable. The fasteners also lock the connecting end 41 and the mating end 42 to a certain extent, applying a force to the connecting end 41 and the mating end 42, making the assembly of the connecting end 41 and the mating end 42 more stable. Simultaneously, the direction of gravity of the upper body 10 is consistent with the assembly direction of the connector 40. Through the gravity of the upper body 10, the stability of the assembly of the connecting end 41 and the mating end 42 can be further improved, making the connection between the connecting end 41 and the mating end 42 more stable, which is beneficial to improving the operational stability of the vehicle body 1. Therefore, through the gravity of the upper body 10 and the force of the fasteners, the connecting end 41 and the mating end 42 can maintain a stable connection, eliminating the need for a locking mechanism to lock the connector 40. This helps reduce the space occupied by the connector 40 and improves the assembly efficiency of the vehicle body 1.

[0089] In some embodiments, the upper vehicle body 10 has at least one first positioning part, and the lower vehicle body 20 has at least one second positioning part, wherein the first positioning part and the corresponding second positioning part are inserted into each other and positioned in a matching manner.

[0090] As can be seen, the positioning and cooperation of the first positioning part and the corresponding second positioning part makes it less likely for the upper body 10 and the lower body 20 to misalign during assembly, thus reducing the assembly difficulty of the upper body 10 and the lower body 20. Furthermore, the cooperation of the first and second positioning parts facilitates alignment of the fastener-corresponding parts of the upper body 10 and the lower body 20, simplifying subsequent fastener installation. Simultaneously, after the upper body 10 and the lower body 20 are assembled, the connecting end 41 and the mating end 42 are also assembled, further improving the assembly efficiency of the vehicle body 1. For example, the first positioning part can be configured as a positioning post, and the second positioning part as a positioning hole. By inserting the positioning post into the positioning hole, the upper body 10 and the lower body 20 can be assembled, reducing the assembly difficulty of the vehicle body 1.

[0091] It is understood that the vehicle body 1 may have multiple first positioning parts and multiple second positioning parts, with each first positioning part corresponding to a second positioning part, in order to improve the assembly accuracy of the upper vehicle body 10 and the lower vehicle body 20, so that the upper vehicle body 10 and the lower vehicle body 20 can be assembled more accurately.

[0092] Please refer to Figure 1 and Figure 2 In some embodiments, the connector 40 further includes a first sealing member 44, which seals between the connecting end 41 and the mating end 42, and surrounds the pins or communication channels of the connector 40 (for example, when the connector 40 is an electrical connector, the connector 40 has pins for electrical connection; or, for example, when the connector 40 is a pipe connector, the connector 40 has a communication channel for pipe connection). The first sealing member 44 can effectively prevent external impurities from entering the connector 40, thereby making the working environment of the pins more stable and improving the operational stability of the connector 40; and / or, the upper body 10 and the lower body 20 enclose a passenger compartment 62. The vehicle body 1 also includes a second sealing component 50, which seals between the upper vehicle body 10 and the lower vehicle body 20. The second sealing component 50 is located around the passenger compartment 62, and the connector 40 is located on the side of the second sealing component 50 adjacent to the passenger compartment 62. Thus, the connector 40 is located between the second sealing component 50 and the passenger compartment 62. The second sealing component 50 can prevent external impurities from entering the connector 40, so that the connector 40 can operate more reliably. At the same time, the second sealing component 50 can also prevent external impurities from contacting the passenger compartment 62, so that the internal environment of the passenger compartment 62 can be cleaner, so that the user does not have to clean the passenger compartment 62 frequently, which improves the ease of use of the vehicle body 1 and the comfort of the passengers.

[0093] As can be seen, the first sealing component 44 and / or the second sealing component 50 can prevent external impurities from entering the connector 40, so that the connector 40 can maintain a stable connection, allowing the vehicle body 1 to adapt to diverse usage environments. If the connector 40 is a pipeline connector, the above-mentioned arrangement can reduce the risk of leakage. Furthermore, the first sealing component 44 and / or the second sealing component 50 are located between the upper vehicle body 10 and the lower vehicle body 20. After the upper vehicle body 10 and the lower vehicle body 20 are assembled, the weight of the upper vehicle body 10 and the force applied by the fasteners can compress the second sealing component 50 and / or the first sealing component 44, so that the second sealing component 50 and / or the first sealing component 44 can have a better sealing effect. This is beneficial to improving the sealing performance and sealing level of the vehicle body 1 at the connector 40 position. For example, the sealing level at the connector 40 can reach IP67.

[0094] For example, the second sealing member 50 may be arranged around the passenger compartment 62. For example, the second sealing member 50 may be configured as a closed annulus, or the second sealing member 50 may be provided only in a part of the passenger compartment 62 where the connector 40 is provided. For example, the second sealing member 50 may be configured as an open annulus. Other sealing structures may be provided in the part of the passenger compartment 62 where the connector 40 is not provided. For example, the upper body 10 and the lower body 20 may cooperate to form a stop structure. The second sealing member 50 and the stop structure can also limit the contact of external impurities with the passenger compartment 62.

[0095] It should be noted that the term "ring" in this article is interpreted broadly, meaning it is not limited to "circular rings," but can also include "polygonal rings," etc. Furthermore, "ring" includes open rings (i.e., non-closed rings, such as C-shaped, U-shaped, Ω-shaped, etc.) and closed rings.

[0096] Optionally, the first sealing member 44 can be fixedly connected to the connecting end 41 or the mating end 42 to improve the positional stability of the first sealing member 44. Of course, the first sealing member 44 can also be set independently of the connecting end 41 and the mating end 42.

[0097] Please refer to Figure 1 In some embodiments, the second sealing member 50 is arranged around the passenger compartment 62. For example, the second sealing member 50 is configured as a closed annulus, which facilitates a more comprehensive seal of the passenger compartment 62. The connector 40 is located between the second sealing member 50 and the passenger compartment 62. The arrangement of the second sealing member 50 makes the installation position of the connector 40 more flexible. The connector 40 only needs to be located between the second sealing member 50 and the passenger compartment 62, which is convenient to adapt to different installation situations.

[0098] Please refer to Figure 1In some embodiments, the abutment region 12 is disposed around the passenger compartment 62 and the abutment region 12 is located on the side of the second sealing member 50 adjacent to the passenger compartment 62, fasteners are disposed in the abutment region 12, and connector 40 is located between the second sealing member 50 and the abutment region 12.

[0099] As can be seen, the abutment area 12 is located inside the second sealing component 50. The abutment area 12 can be used to support the upper vehicle body 10 so that the weight of the upper vehicle body 10 can be distributed and borne by the abutment area 12. Thus, the force exerted by the upper vehicle body 10 on the second sealing component 50 will not be too large, which helps to reduce the requirements on the second sealing component 50. At the same time, the abutment area 12 can achieve a certain degree of sealing between the upper vehicle body 10 and the lower vehicle body 20.

[0100] In addition, fasteners are located in the abutment area 12, and connector 40 is located between the second sealing component 50 and the abutment area 12, so that connector 40 and the second sealing component 50 are less likely to interfere with the fasteners. At the same time, the second sealing component 50 is located outside the abutment area 12, so that after the upper body 10 and the lower body 20 are disassembled, the staff can more easily observe and access the second sealing component 50, which facilitates the maintenance and replacement of the second sealing component 50.

[0101] Please refer to Figure 1 and Figure 4 In some embodiments, the upper body 10 and the lower body 20 enclose a passenger compartment 62 and a front compartment 64. The upper body 10 includes a front bulkhead 14, which is located between the passenger compartment 62 and the front compartment 64. A connecting end 41 is fixed to the lower end of the front bulkhead 14, so the connecting end 41 is at least partially located within the passenger compartment 62. The lower body 20 includes a crossbeam 22, which is located below the front bulkhead 14. A mating end 42 is fixed to the crossbeam 22, so the mating end 42 is at least partially located within the front compartment 64. At least a portion of the second sealing member 50 and / or the first sealing member 44 are sandwiched between the front bulkhead 14 and the crossbeam 22.

[0102] As can be seen, taking connector 40 as an electrical connector as an example, after the upper body 10 and lower body 20 are assembled, the connecting end 41 on the front bulkhead 14 and the mating end 42 on the crossbeam 22 are also assembled, so that the wiring harness located in the front compartment 64 (e.g., the second wiring harness mentioned above) can be indirectly connected to the wiring harness in the passenger compartment 62 (e.g., the first wiring harness mentioned above) through connector 40, thereby realizing the electrical connection between the wiring harness in the front compartment 64 and the wiring harness in the passenger compartment 62. At least a portion of the second sealing member 50 and / or the first sealing member 44 are sandwiched between the front bulkhead 14 and the crossbeam 22. The second sealing member 50 and / or the first sealing member 44 can prevent external impurities from entering the connector 40, which facilitates improving the sealing level of the connector 40, so that the vehicle body 1 can adapt to different usage environments.

[0103] For example, if a vehicle 2 using body 1 has water wading requirements, such as a vehicle with a skateboard chassis, in related technologies, because the assembly direction of the connector (the connecting end and mating end are inserted and removed along the vehicle's driving direction and front-to-back direction) is different from the assembly direction of the vehicle body, the sealing performance of the connector is limited, the sealing level is low, and the waterproof effect is poor. This greatly restricts the installation height of the connector. For example, the connecting end can only be located at a higher position on the front bulkhead, and when the connecting end is connected to the passenger compartment wiring harness, a hole needs to be opened at a higher position on the front bulkhead. However, according to the vehicle body 1 of this application embodiment, at least a portion of the second sealing member 50 and / or the first sealing member 44 can restrict external impurities from entering the connector 40, while utilizing the weight of the upper body 10 and the fasteners. The applied force compresses the second sealing component 50 and / or the first sealing component 44, so that the second sealing component 50 and / or the first sealing component 44 can have a better sealing effect, so that the sealing rating of the connector 40 can reach IP67. The connector 40 has a better sealing effect, so that the setting position of the connector 40 is more flexible. For example, the connection end 41 can be located at a lower position of the front bulkhead 14. When the connection end 41 is connected to the wiring harness of the passenger compartment 62, the hole can be opened at a lower position on the front bulkhead 14, so that there is no need to make a hole at a higher position on the front bulkhead 14 (for example, the connection end 41 is fixed at the lower end of the front bulkhead 14, and the lower end of the front bulkhead 14 is opened to set the connection end 41), which facilitates the improvement of the overall NVH performance of the passenger compartment 62.

[0104] Please refer to Figure 1 and Figure 4 In some embodiments, connector 40 is offset from crossbeam 22 in its length direction (e.g. Figure 4 The connector 40 is positioned at the center (in the BB' direction) so that when the vehicle body 1 is used in the vehicle 2, the connector 40 is offset from the power source of the vehicle 2, such as the engine or motor, in the vehicle width direction. At the same time, the wiring harness in the front compartment 64 is convenient for routing the wiring to the adjacent corresponding wheels, which helps to shorten the wiring path and facilitates wiring. In addition, when the connector 40 needs to be repaired, the off-center position provides more operating space and makes it easier for the staff to operate.

[0105] Please refer to Figure 1In some embodiments, the front bulkhead 14 includes a first wall 140 and a second wall 142. The first wall 140 is horizontally disposed and has a first mounting hole 141. A connecting end 41 is disposed at the first mounting hole 141. The second wall 142 is bent and connected to the end of the first wall 140 away from the passenger compartment 62. The second wall 142 and the first wall 140 define a first cavity 143 for accommodating the connecting end 41. The crossbeam 22 includes a third wall 220 and a fourth wall 222. The third wall 220 is parallel to the first wall 140 and has a second mounting hole 221. A mating end 42 is disposed at the second mounting hole 221. The fourth wall 222 is bent and connected to the end of the third wall 220 away from the passenger compartment 62. The fourth wall 222 and the third wall 222 define a second cavity 223 for accommodating the mating end 42.

[0106] It is evident that the structure of the front bulkhead 14 and the crossbeam 22 is relatively simple, which facilitates the improvement of the processing efficiency of the front bulkhead 14 and the crossbeam 22, and is beneficial to improving the manufacturing efficiency of the vehicle body 1; the connecting end 41 is located at the first mounting hole 141 formed by the first wall 140, and the mating end 42 is located at the second mounting hole 221 formed by the third wall 220. The third wall 220 and the first wall 140 are parallel, which makes the setting position of the connecting end 41 and the mating end 42 more compatible with the assembly and disassembly direction of the connecting end 41 and the mating end 42, so that the assembly of the connecting end 41 and the mating end 42 is simpler, and it is easier to realize the plug-in connection of the connecting end 41 and the mating end 42 in the vertical direction; the second wall 142 is bent and connected to the end of the first wall 140 away from the passenger compartment 62, and the second wall 142 is limited to the first wall 140. A first cavity 143 is defined to accommodate the connecting end 41. The first cavity 143 provides a relatively stable environment for the connecting end 41. When the vehicle body 1 is hit by a collision, the second wall 142 can block external materials from impacting the connecting end 41, so that the connecting end 41 is not easily damaged and its service life is improved. The fourth wall 222 is bent and connected to the end of the third wall 220 away from the passenger compartment 62. The fourth wall 222 and the third wall 220 define a second cavity 223 to accommodate the connecting end 41. The second cavity 223 provides a relatively stable environment for the mating end 42. When the vehicle body 1 is hit by a collision, the fourth wall 222 can block external materials from impacting the mating end 42, so that the mating end 42 is not easily damaged and its service life is improved.

[0107] It is understood that the side of the connecting end 41 away from the mating end 42 needs to connect to the crew compartment 62 wiring harness, meaning that the crew compartment 62 wiring harness is at least partially located within the first cavity 143. The routing direction of the crew compartment 62 wiring harness can be parallel to the first wall 140, perpendicular to the first wall, or at a certain angle to the first wall 140. Similarly, the side of the mating end 42 away from the connecting end 41 needs to connect to the front compartment 64 wiring harness, meaning that the front compartment 64 wiring harness is at least partially located within the second cavity 223. The routing direction of the front compartment 64 wiring harness can be parallel to the third wall 220, perpendicular to the third wall 220, or at a certain angle to the third wall 220. Therefore, this application does not restrict the routing direction of the front compartment 64 wiring harness and the crew compartment 62 wiring harness; the operator can determine the routing direction based on the actual installation requirements.

[0108] Please refer to Figures 1-3 In some embodiments, the connecting end 41 includes a first base 410, a first terminal 411, and a first mounting base 412. The first terminal 411 is disposed on the first base 410, and the first mounting base 412 is disposed on the outer peripheral wall of the first base 410 and surrounds the first base 410. The first mounting base 412 is connected to the side of the first wall 140 opposite to the third wall 220. The second wall 142 and the first wall 140 define a first cavity 143 for accommodating the connecting end 41. Due to the above-mentioned arrangement of the first mounting base 412, the height of the first base 410 protruding from the first wall 140 can be reduced, so that the connecting end 41 can make fuller use of the space of the first cavity 143, making the structure of the vehicle body 1 more compact; and / or, the mating end 42 includes A second base 420, a second terminal 421, and a second mounting base 422 are provided. The second terminal 421 is disposed on the second base 420 and is adapted to be electrically connected to the first terminal 411 of the connecting end 41. The second mounting base 422 is disposed on the outer peripheral wall of the second base 420 and surrounds the second base 420. The second mounting base 422 is connected to the side of the third wall 220 opposite to the first wall 140. The fourth wall 222 and the third wall 220 define a second cavity 223 for accommodating the connecting end 41. Due to the provision of the second mounting base 422, the height of the second base 420 protruding from the third wall 220 can be reduced, so that the mating end 42 can make fuller use of the space of the second cavity 223, making the structure of the vehicle body 1 more compact. It can be understood that the first terminal 411 is one of a pin and a slot, and the second terminal 421 is the other of a pin and a slot. The pin and slot are connected by insertion to realize the electrical connection between the connecting end 41 and the mating end 42.

[0109] It is evident that the arrangement of the first mounting base 412 and the second mounting base 422 helps to reduce the opening size of the first mounting hole 141 and the second mounting hole 221, thereby reducing the structural weakening caused by the connector 40 to the front bulkhead 14 and the crossbeam 22. Furthermore, it prevents the protrusion height of the first base 410 and the second base 420 from being too high. When the connecting end 41 and the mating end 42 are assembled, it is less likely to impose excessive restrictions on the gap between the first wall 140 and the third wall 220. For example, the gap between the first wall 140 and the third wall 220 will not be too large, making the structure of the vehicle body 1 more compact. When the second sealing component 50 and / or the first sealing component 44 are provided between the first wall 140 and the third wall 220, the second sealing component 50 and / or the first sealing component 44 need to seal the gap between the first wall 140 and the third wall 220. Since the gap between the first wall 140 and the third wall 220 will not be too large, it facilitates reliable sealing by the second sealing component 50 and / or the first sealing component 44.

[0110] For example, the first mounting base 412 is a flat plate structure so that the first mounting base 412 and the first wall 140 can fit better together, facilitating a reliable connection between the first mounting base 412 and the first wall 140; the second mounting base 422 is a flat plate structure so that the second mounting base 422 and the third wall 220 can fit better together, facilitating a reliable connection between the second mounting base 422 and the third wall 220.

[0111] Of course, in other embodiments of this application, the first mounting base 412 may also be connected to the side of the first wall 140 facing the third wall 220, and / or the second mounting base 422 may be connected to the side of the third wall 220 facing the first wall 140.

[0112] In some embodiments, a first reinforcing structure is provided on the first wall 140, and the first reinforcing structure is disposed adjacent to the first mounting hole 141; and / or, a second reinforcing structure is provided on the third wall 220, and the second reinforcing structure is disposed adjacent to the second mounting hole 221.

[0113] As can be seen, the first reinforcing structure is disposed adjacent to the first mounting hole 141. The first reinforcing structure can enhance the structural strength and stability of the front bulkhead 14 at the first mounting hole 141, which is beneficial to further improving the installation reliability of the connecting end 41; and / or, the second reinforcing structure is disposed adjacent to the second mounting hole 221. The second reinforcing structure can enhance the structural strength and stability of the crossbeam 22 at the second mounting hole 221, which is beneficial to further improving the installation reliability of the mating end 42. Exemplarily, the first reinforcing structure may refer to locally thickening the edge portion of the first mounting hole 141, or the first reinforcing structure may refer to providing reinforcing ribs at the edge portion of the first mounting hole 141; the second reinforcing structure may refer to locally thickening the edge portion of the second mounting hole 221, or the second reinforcing structure may refer to providing reinforcing ribs at the edge portion of the second mounting hole 221.

[0114] Secondly, embodiments of this application provide a vehicle 2, including the vehicle body 1 of the first aspect.

[0115] In the above technical solution, since the assembly of the vehicle body 1 is relatively convenient, the use of the vehicle body 1 can improve the assembly efficiency of the vehicle 2.

[0116] It is understood that the specific type of vehicle 2 referred to in the embodiments of this application is not limited. For example, vehicle 2 can be a fuel vehicle, a gas vehicle, or a new energy vehicle. New energy vehicles can be pure electric vehicles, hybrid electric vehicles, fuel cell electric vehicles, range-extended electric vehicles, solar electric vehicles, gas fuel vehicles (such as hydrogen engine vehicles), or biofuel vehicles (such as vehicles powered by ethanol, biodiesel, etc.).

[0117] Please refer to Figure 4 In some embodiments, the vehicle 2 also includes a power source, a transmission mechanism and wheels 74. The power source is located in the front compartment 64 formed between the upper body 10 and the lower body 20. The wheels 74 are mounted on the lower body 20 through a suspension system. The transmission mechanism is connected between the power source and the wheels 74. In the width direction of the vehicle 2, the connector 40 is offset from the power source.

[0118] It is evident that the power source can transmit power to the wheels 74 through the transmission mechanism, thereby driving the vehicle 2; in the width direction of the vehicle 2 (e.g. Figure 4 In the BB' direction, the connector 40 is staggered from the power source. On a vertical plane parallel to the width direction of the vehicle 2, the orthographic projection of the connector 40 and the orthographic projection of the power source do not overlap. The connector 40 can make fuller use of the empty space in the front compartment 64, so that the structure of the vehicle 2 is more compact. At the same time, the power source is less likely to affect the arrangement of the connector 40, reducing the wiring restrictions on the connector 40 and facilitating the improvement of the assembly efficiency of the vehicle 2.

[0119] For example, the crossbeam 22 is provided with two mating ends 42 spaced apart along its length direction. The two mating ends 42 are located on both sides of the center position of the crossbeam 22 in its length direction. A portion of the wiring harness of the front compartment 64 can be adjacent to the wheel wiring on one side and connected to one of the mating ends 42 located adjacent to the wheel on that side. Another portion of the wiring harness of the front compartment 64 can be adjacent to the wheel wiring on the other side and connected to the other mating end 42 located adjacent to the wheel on that side.

The connecting end 41 includes a first base 410, a first terminal 411, and a first mounting base 412. The first terminal 411 is located on the first base 410. The first mounting base 412 is disposed on the outer peripheral wall of the first base 410 and surrounds the first base 410. The first mounting base 412 is connected to the side of the first wall 140 opposite to the third wall 220. The mating end 42 is fixed to the crossbeam 22. The crossbeam 22 includes the third wall 220 and the fourth wall 222. The third wall 220 is parallel to the first wall 140 and forms a second mounting hole 221. The mating end 42 is disposed at the second mounting hole 221. The fourth wall 222 is bent and connected to the end of the third wall 220 away from the passenger compartment 62.

The second mounting seat 422 is connected to the side of the third wall 220 opposite to the first wall 140. The connector 40 is offset from the center position of the crossbeam 22 in its length direction.

[0123] There are multiple connectors 40. The upper body 10 includes at least one first wire harness, and the lower body 20 includes at least one second wire harness. Some of the connectors 40 are electrical connectors, and at least one of all the first wire harnesses and at least one of all the second wire harnesses are electrically connected through the connectors 40.
