Abstract
Description
Technical Field
[0001] This application relates to vehicle component technology, and more particularly to a vehicle body structure and a vehicle. Background Technology
[0002] Refrigerated trucks are widely used in industries such as food and pharmaceuticals that are sensitive to transportation temperatures. Refrigerated trucks maintain a low-temperature environment for goods through the sealing and insulation of their refrigerated containers. Refrigerated minipassenger vans (VANs) are widely used due to their high space utilization and strong cargo capacity.
[0003] In related technologies, the spare tire of a conventional VAN model is mounted on the vehicle chassis via a spare tire lifting device. The vehicle chassis has a pre-drilled lifting hole located at the rear of the VAN's cargo compartment. The driver can operate the spare tire lifting device through the lifting hole to lift and lower the spare tire, thus enabling the storage and retrieval of the spare tire.
[0004] However, when a refrigerated compartment is added to a regular VAN model, the overall sealed structure of the refrigerated compartment will cover the original lifting holes on the vehicle chassis. Therefore, refrigerated trucks are mostly designed without a spare tire. If a tire blows out, the driver cannot change the tire directly, resulting in a poor user experience. Utility Model Content
[0005] This application provides a vehicle body structure and a vehicle to solve the technical problem that refrigerated trucks cannot be equipped with tire lifting devices in related technologies.
[0006] On the one hand, this application provides a vehicle body structure, including:
[0007] Vehicle chassis and insulated compartment mounted on the vehicle chassis;
[0008] A lifting assembly is connected to the vehicle chassis. The lifting assembly is used to install a spare tire. The lifting assembly has a drive unit on the side facing the vehicle chassis. The drive unit is configured to drive the spare tire to lift and lower under the action of external force.
[0009] The vehicle chassis is provided with a first clearance hole to avoid the drive unit, and the insulated box is provided with a second clearance hole that communicates with the first clearance hole.
[0010] A sealing assembly is detachably disposed on at least one of the first clearance hole and the second clearance hole to close at least one of the first clearance hole and the second clearance hole.
[0011] In some possible implementations, the sealing assembly includes a first sealing member detachably disposed on the first clearance hole and a second sealing member detachably disposed on the second clearance hole.
[0012] In some possible implementations, the first sealing component includes a resilient end cap disposed on the first clearance hole, the resilient end cap having an operating part on the side facing the second clearance hole, the operating part being configured to drive the resilient end cap out of the first clearance hole under the action of an external force.
[0013] In some possible implementations, the resilient end cap is mounted into the first clearance hole and is interference-fitted with the first clearance hole.
[0014] In some possible implementations, the resilient end cap has a mounting portion for extending into the first clearance hole, the outer wall of the mounting portion being configured with a circumferentially extending groove for engaging with an edge portion of the first clearance hole.
[0015] In some possible implementations, the second sealing component includes a mounting end cap and a movable end cap disposed on the mounting end cap, the mounting end cap being fixedly connected to the first clearance hole, and the movable end cap being detachably connected to the mounting end cap.
[0016] In some possible implementations, at least a portion of the mounting end cap is inserted into the first clearance hole, and the mounting end cap is threadedly connected to the movable end cap.
[0017] In some possible implementations, the end of the mounting end cap that is inserted into the first clearance hole has a first annular portion that protrudes in a direction away from the inner wall of the first clearance hole. The first annular portion is provided with a sealing ring coaxial with the first clearance hole, and the sealing ring is used to press against the movable end cap that is screwed into the mounting end cap.
[0018] In some possible implementations, the end of the mounting cap that is not inserted into the first clearance hole is provided with a second annular portion, the second annular portion protruding in a direction away from the first annular portion, and the second annular portion being connected to the floor of the insulated compartment.
[0019] On the other hand, this application provides a vehicle, including a vehicle body and a body structure as described in any of the preceding claims disposed on the vehicle body.
[0020] The vehicle body structure and vehicle provided in this application, in the vehicle body structure, through the connected first clearance hole and second clearance hole, form a dedicated working channel directly reaching the lifting component drive unit. Thus, the refrigerated vehicle can retain the normal function of the original spare tire lifting. The sealing component provided on at least one of the first clearance hole and the second clearance hole effectively seals at least one of the first clearance hole and the second clearance hole. In the non-operating state, the sealing component blocks the gas exchange and heat conduction between the inside and outside environment of the insulated compartment, which is conducive to ensuring the normal sealing and heat preservation performance of the insulated compartment.

[0038] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or apparatus.
[0039] Refrigerated trucks are widely used in industries such as food and pharmaceuticals that are sensitive to transportation temperature. Their core requirement is to maintain the low temperature environment of goods through the sealing and insulation of the refrigerated cargo compartment. VAN-type refrigerated trucks (box trucks) are widely used because of their high space utilization and strong cargo capacity.
[0040] In conventional vans, the spare tire is usually located at the rear of the cargo bed and accessed via a tire lift. However, when a refrigerated compartment is added, its sealed structure obscures the original tire lift hole on the vehicle chassis. Therefore, refrigerated trucks often lack a spare tire. In the event of a tire blowout, the driver cannot directly change the tire, resulting in a poor user experience.
[0041] Based on this, one or more embodiments of this application provide a vehicle body structure and a vehicle. In the vehicle body structure, a dedicated working channel is formed by the connected first clearance hole and the second clearance hole, which directly leads to the lifting component drive unit. This allows the refrigerated vehicle to retain the normal function of the original spare tire lifting. A sealing component provided on at least one of the first clearance hole and the second clearance hole provides an effective seal for the working channel. In the non-operating state, the sealing component blocks the gas exchange and heat conduction between the inside and outside environment of the insulated compartment, which is beneficial to ensuring the normal sealing and heat preservation performance of the insulated compartment.
[0042] The following description, in conjunction with the accompanying drawings, illustrates the solutions of the embodiments of this application.
[0043] like Figure 1 As shown, the vehicle body structure of this application embodiment includes a vehicle chassis 100 and an insulated compartment 200 disposed on the vehicle chassis 100. A lifting assembly 300 is connected to the vehicle chassis 100 and is used to install a spare tire 320. A drive unit 310 is provided on the side of the lifting assembly 300 facing the chassis. The drive unit 310 is configured to drive the spare tire 320 to rise and fall under the action of external force. A first clearance hole 110 is provided on the vehicle chassis 100 to avoid the drive unit 310, and a second clearance hole 210 communicating with the first clearance hole 110 is provided on the insulated compartment 200. A sealing assembly 400 is detachably disposed on at least one of the first clearance hole 110 and the second clearance hole 210 to close at least one of the first clearance hole 110 and the second clearance hole 210.
[0044] As can be seen from the above description, in the vehicle body structure of this embodiment, a second clearance hole 210 is directly opened on the insulated compartment 200. The second clearance hole 210 communicates with the first clearance hole 110 on the vehicle chassis 100, thereby forming an operating channel from the insulated compartment 200 to the drive unit 310. Operators can directly operate the drive unit 310 through the operating channel, enabling the vehicle to have the insulation and refrigeration performance of the insulated compartment 200 while retaining the complete operating function of the original vehicle lifting assembly 300, which is conducive to the normal storage and retrieval of the spare tire 320. In addition, the sealing assembly 400 detachably installed on at least one of the first clearance hole 110 and the second clearance hole 210 can keep the operating channel sealed in the non-operating state, blocking the gas exchange and heat conduction between the insulated compartment 200 and the external environment, thereby helping to ensure the normal insulation and refrigeration performance of the insulated compartment 200.
[0045] Since the first clearance hole 110 and the second clearance hole are connected, they form an operating channel from the insulated box 200 to the drive unit 310. After the sealing component 400 is removed, the operating channel is exposed. Operators can operate the drive unit 310 and raise and lower the spare tire 320 using the original spare tire 320 loading and unloading tools without the need for other maintenance tools, making it more adaptable.
[0046] The vehicle body structure in this embodiment can be used on VAN models equipped with refrigerated cabinets, or other vans with sealed compartments, such as dry cargo vans, express delivery vehicles, or RVs. Vehicles that cannot normally raise or lower the spare tire 320 due to interference between the sealed compartment and the lifting assembly 300 on the vehicle chassis 100 are also acceptable. This embodiment does not impose absolute limitations on this.
[0047] In this embodiment, the lifting component 300 can be a mature vehicle component from the relevant technology, and the connection between the vehicle chassis 100 and the lifting component 300 can be set with reference to the relevant technology.
[0048] For example, the lifting assembly 300 includes a winch assembly, a drive unit 310, a wire rope, and a lifting bracket. The winch assembly is responsible for winding the wire rope and providing lifting power. The drive unit 310 is used to receive torque input from external tools. The drive unit 310 is typically a square hole, spline hole, or hexagonal hole provided on the vehicle chassis 100. The lifting bracket is used to pass through the center hole of the spare tire 320's wheel hub and fix the tire.
[0049] During the operation of the lifting assembly 300, the operator inserts the spare tire 320 loading / unloading tool into the drive unit 310 and rotates it, causing the winch assembly to release the wire rope. The spare tire 320 descends under gravity until it hits the ground, where it can be retrieved. Conversely, rotating the drive unit 310 in the opposite direction causes the winch assembly to wind up the wire rope, lifting the spare tire 320 upwards until it locks, completing the spare tire 320 storage process.
[0050] like Figure 2 and Figure 3 As shown, in some embodiments, the sealing assembly 400 includes a first sealing member 410 disposed on the first clearance hole 110 and a second sealing member 420 disposed on the second clearance hole 210.
[0051] Here, the first sealing component 410 installed on the first clearance hole 110 of the vehicle chassis 100 can provide basic sealing and environmental protection, preventing road surface water, mud, salt spray or other water vapor from entering the work passage and eroding the insulated box 200. The second sealing component 420 installed on the second clearance hole 210 of the insulated box 200 can further ensure airtightness and thermal insulation performance, block the heat exchange between the inside and outside of the insulated box 200, prevent the cold energy of the insulated box 200 from being lost through the work passage, and also prevent the intrusion of high temperature and high humidity air from the outside into the insulated box 200, causing frost to form on the inner wall of the insulated box 200.
[0052] The dual sealing of the first sealing component 410 and the second sealing component 420 further enhances the insulation reliability and safety of the insulated box 200, achieving the dual effects of mechanical protection and heat exchange protection.
[0053] For example, the first sealing component 410 includes an elastic end cap 411 that covers the first clearance hole 110. The elastic end cap 411 has an operating part 412 on the side facing the second clearance hole 210. The operating part 412 is configured to drive the elastic end cap 411 out of the first clearance hole 110 under the action of external force.
[0054] The elastic end cap 411 and the operating part 412 can be of an integral structure. The elastic end cap 411 and the operating part 412 can be bonded or directly injection molded as a single unit. In some embodiments, the elastic end cap 411 and the operating part 412 can also be snap-fitted together. This is not an absolute limitation in the embodiments of this application.
[0055] When placing the elastic end cap 411 through the second clearance hole 210 of the insulated compartment 200, the operating part 412 is used for guidance and positioning to ensure that the elastic end cap 411 is coaxially aligned with the first clearance hole 110. When installing the first sealing component 410, the operator is located inside the insulated compartment 200 and it is not convenient to directly observe the first clearance hole 110 on the chassis. Therefore, the extended operating part 412 can guide the falling path of the elastic end cap 411, making it easier for the operator to operate the elastic end cap 411 to seal the first clearance hole 110 and reducing the difficulty of operation.
[0056] Here, the end of the operating part 412 away from the elastic end cap 411 may be equipped with a handle, which may be circular or cylindrical, mainly to facilitate the operation of the operator.
[0057] Furthermore, the elastic end cap 411 is installed into the first clearance hole 110 and is connected to the first clearance hole 110 by interference fit.
[0058] The elastic end cap 411 can be supported by a material with certain deformation properties, such as EPDM rubber, neoprene rubber, silicone rubber, etc. The elastic end cap 411 can be prepared by compression molding process. When the elastic end cap 411 is aligned with the first clearance hole 110, the operator uses a spare tire 320 wrench or other loading and unloading tools to press the periphery of the elastic end cap 411, so that it is squeezed into the first clearance hole 110 to form an interference fit.
[0059] like Figure 4 As shown, in some embodiments, the resilient end cap 411 has a mounting portion 4111 for extending into the first clearance hole 110, and the outer side wall of the mounting portion 4111 is constructed with a groove 4112 extending circumferentially around itself for engaging with the edge portion of the first clearance hole 110.
[0060] In the above embodiment, the mounting part 4111 gradually contracts in the direction away from the operating part 412, thereby forming an inclined transition surface. The gradually contracting mounting part 4111 can be more easily inserted into the first clearance hole 110. During the process of the mounting part 4111 being inserted into the first clearance hole 110, the slot 4112 gradually moves down past the edge of the first clearance hole 110, and the elastic end cap 411 undergoes elastic deformation and rebounds, so that the slot 4112 engages with the edge of the first clearance hole 110, forming an axial constraint and fixation between the elastic end cap 411 and the first clearance hole 110. This setting can effectively prevent road surface water, mud and other foreign objects from entering the operation channel, and the waterproof and dustproof effect is better.
[0061] Therefore, the entire first sealing component 410 can be installed and removed directly from above through the working channel. Operators do not need to crawl under the vehicle. They can operate the lifting component 300 by opening the second sealing component 420 and the first sealing component 410 in sequence, making the operation more convenient.
[0062] As an alternative implementation, the resilient end cap 411 and the first clearance hole 110 can be connected by a threaded connection. When using a threaded connection, it is necessary to ensure the sealing of the resilient end cap 411 and the first clearance hole 110, which will not be elaborated in this embodiment.
[0063] like Figure 4 As shown, in some embodiments, the second sealing component 420 includes a mounting end cap 421 and a movable end cap 422 disposed on the mounting end cap 421. The mounting end cap 421 is fixedly connected to the first clearance hole 110, and the movable end cap 422 is detachably connected to the mounting end cap 421.
[0064] Here, the mounting end cap 421 can be made of wear-resistant and corrosion-resistant materials, such as engineering plastics or metals. The movable end cap 422 can be made of rubber or plastic. The mounting end cap 421 and the movable end cap 422 are actually separate designs. The mounting end cap 421 has a rigid ring or flange structure and is fixed to the floor of the insulation box 200 by fasteners such as bolts and rivets, or directly fixed to the floor of the insulation box by welding and high-strength adhesive.
[0065] The mounting end cap 421 has a through hole in the center that connects to the working channel. The movable end cap 422 is detachably connected to the mounting end cap 421, thereby blocking or opening the working channel.
[0066] In some embodiments, at least a portion of the mounting end cap 421 is inserted into the first clearance hole 110, and the mounting end cap 421 is threadedly connected to the movable end cap 422.
[0067] For example, the inner wall of the mounting end cover 421 is machined with an internal thread section, and the outer wall of the movable end cover 422 is machined with an external thread section that mates with the internal thread section. The movable end cover 422 is locked or separated from the mounting end cover 421 by turning it.
[0068] As an alternative implementation, the movable end cap 422 and the mounting end cap 421 are detachably connected by a snap-fit connection. For example, the movable end cap 422 is provided with a hook, and the mounting end cap 421 is provided with a snap-fit groove. When the movable end cap 422 is inserted into the mounting end cap 421, the hook and the snap-fit groove cooperate to form a snap-fit seal. When it is necessary to remove the movable end cap 422, the operator can use external force to turn or pry the movable end cap 422, forcibly deforming it to overcome the snap-fit effect and detach it from the mounting end cap 421.
[0069] In some embodiments, the outer surface of the active end cap 422 may integrate components such as handles and knobs to optimize human-computer interaction, making its operation more convenient and effortless.
[0070] like Figure 4 As shown, in this embodiment of the application, the bottom of the end of the mounting end cap 421 inserted into the first clearance hole 110 is provided with a first annular portion 4211. The first annular portion 4211 protrudes in a direction away from the inner wall of the first clearance hole 110. A sealing ring 4212 coaxial with the first clearance hole 110 is provided on the first annular portion 4211. The sealing ring 4212 is used to press against the movable end cap 422 screwed into the mounting end cap 421.
[0071] The first annular portion 4211 forms an annular support surface on the inner side wall of the mounting end cover 421. The sealing ring 4212 is padded on the first annular portion 4211. The sealing ring 4212 can be made of a material with certain elastic deformation properties, such as an O-ring rubber seal, a rubber flat washer, or a foam seal. The sealing ring 4212 is coaxially arranged with the second clearance hole 210 and the mounting end cover 421 itself.
[0072] During the process of screwing the movable end cap 422 into the mounting end cap 421, the threaded movable end cap 422 exerts a downward axial force. When the movable end cap 422 is screwed into the bottom of the mounting end cap 421, it presses against the sealing ring 4212 on the first annular portion 4211. The compressed sealing ring 4212 elastically deforms, blocking the working channel and forming a static seal. This arrangement further enhances the sealing effect of the second sealing component 420 on the second clearance hole 210, preventing heat exchange between the insulation box 200 and the external environment, and avoiding damage to the insulation box 200.
[0073] like Figure 4 As shown, in some embodiments, the end of the mounting end cap 421 that is not inserted into the first clearance hole 110 is provided with a second annular portion 4213. The second annular portion 4213 protrudes in a direction away from the first annular portion 4211 and is connected to the floor of the insulated box 200.
[0074] In the above embodiment, the second annular portion 4213 is used for connection and sealing with the floor of the insulated compartment 200. The second annular portion 4213 and the floor of the insulated compartment 200 can be bonded with a high-viscosity structural adhesive. The second annular portion 4213 increases the contact area between the mounting end cap 421 and the insulated compartment 200, further ensuring the airtightness of the connection between the mounting end cap 421 and the second clearance hole 210, and preventing cold air or condensate in the insulated compartment 200 from leaking through the gaps in the mounting end cap 421 and the second clearance hole 210.
[0075] Another embodiment of this application provides a vehicle, including a vehicle body and a vehicle body structure as described in any of the above embodiments disposed on the vehicle body.
[0076] Since the vehicle includes the body structure as described in any of the above embodiments, it has all the advantages of a body structure.
