Description

Technical Field

[0001] This invention relates to the field of vehicle interior space expansion technology, and in particular to a vehicle body sliding system with a rack and pinion linear guide or linear bearing. Background Technology

[0002] Existing vehicles and motorhomes can be equipped with sliding-out bodies to increase interior space. When in motion, the outer wall of the sliding-out body is flush with the exterior of the vehicle. When the vehicle stops, the sliding-out body slides out from the opening, thus increasing the interior space.

[0003] CN202111541306.4 discloses a motorhome extension mechanism and a motorhome. The sliding mechanism is located under and on the side of the vehicle body. It is not integrated, occupies a lot of space, is inconvenient to install, and is unstable in operation.

[0004] US202117408020A discloses a sliding device located on both sides of a sliding housing. Due to the complexity of the mechanism used, the telescopic drive device occupies a large space, is inconvenient to maintain, and increases the cost of use.

[0005] Regarding the aforementioned technologies, the inventors believe that the sliding mechanism of the vehicle body sliding system is relatively large, complex to install, and costly. Therefore, they believe that the sliding mechanism of the vehicle body sliding system has the problem of occupying a large amount of space. Summary of the Invention

[0006] To address the issue of large space requirements associated with vehicle sliding-out mechanisms, this invention provides a vehicle sliding-out system. The sliding-out mechanism of this system is integrated into the lower sides of the corresponding sliding-out body, resulting in a compact and aesthetically pleasing design. It eliminates the need to disassemble the vehicle's lower chassis; simply fixing the base plate of the support frame to the vehicle body allows the sliding-out system to be positioned at the vehicle's opening. This enables the sliding-out body to slide out and retract, increasing usable vehicle space and facilitating easy installation and disassembly.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a vehicle body sliding system with a rack and pinion linear guide or linear bearing, comprising a sliding body, a drive device, a sliding assembly, a support frame, and a carrier assembly. The sliding body is disposed at an opening in the vehicle body. The drive device meshes with the sliding assembly. The sliding assembly is fixed above the support frame. The sliding assembly, the drive device, and part of the support frame are integrated inside the carrier assembly. The bottom of the carrier assembly is provided with an elongated opening. The carrier assembly slides out and retracts back and forth at the lower end of the support frame through the elongated opening.

[0008] By adopting the above technical solution, the sliding component, drive device, and part of the support frame are integrated in the carrier box assembly, which can isolate the sliding component and drive device from external influences, facilitate installation and disassembly, improve appearance, and increase the interior space of the vehicle.

[0009] Preferably, the sliding assembly involves three structures: a rack and pinion guide combined sliding assembly, a rack and pinion guide composite sliding assembly, or a rack and pinion optical axis combined sliding assembly. The rack and pinion guide combined sliding assembly includes a guide rail, a slider, a rack, and a rack fixing bracket. The guide rail is slidably connected to the slider. One end of the guide rail is provided with a combined guide rail fixing hole one, the other end with a combined guide rail fixing hole two, and the top of the guide rail with a combined guide rail fixing hole three. The rack fixing bracket has a rack fixing bracket hole one and a rack fixing bracket hole two, with the combined guide rail fixing hole three corresponding to the rack fixing bracket hole two, used to connect the guide rail and the rack fixing bracket. The rack has a rack connecting hole one, with the rack connecting hole one corresponding to the rack fixing bracket hole one, used to connect the rack and the rack fixing bracket. The rack is fixed to the guide rail by the rack fixing bracket, and the guide rail is slidably fixed inside the slider.

[0010] By adopting the above technical solution, the guide rail can slide inside the slider, reducing friction. The rack and guide rail are connected together to make linear motion, and the slider can bear the weight transmitted by the guide rail.

[0011] Preferably, the rack and pinion guide composite sliding assembly includes a rack and pinion guide composite and a slider. The rack and pinion guide composite is provided with a rack and a guide rail integrated into one unit. One end of the rack and pinion guide composite is provided with a composite fixing hole three, and the other end is provided with a composite fixing hole four. The rack and pinion guide composite is slidably fixed inside the slider.

[0012] By adopting the above technical solution, the rack and pinion guide composite sliding assembly has a simpler structure than the rack and pinion guide combined sliding assembly, while still achieving linear motion of the rack driving the guide rail, making production and installation more convenient.

[0013] Preferably, the rack and pinion optical axis combined sliding assembly includes a rack three, a rack three connecting hole three, an open linear bearing, an open bearing fixing hole, a linear optical axis, a linear optical axis fixing hole, a linear optical axis bracket, a bracket fixing hole one, a bracket fixing hole two, a linear optical axis fixing hole five, and a linear optical axis fixing hole six; the rack three connecting hole three is correspondingly provided with the bracket fixing hole two, used to connect the rack three and the linear optical axis bracket, the bracket fixing hole one is correspondingly provided with the linear optical axis fixing hole, used to connect the linear optical axis bracket and the linear optical axis; the rack three is fixedly connected to the linear optical axis through the linear optical axis bracket, and the linear optical axis is slidably fixed inside the open linear bearing.

[0014] By adopting the above technical solution, it is also possible to achieve the same effect of rack and pinion driving linear optical axis to support load and perform linear motion, and the linear bearing is cheaper and easier to install than the combined rack and pinion guide.

[0015] Preferably, the driving device includes a drive base, a motor, a reducer, and a gear. The output shaft of the motor is connected to the reducer, the reducer is mounted on the drive base, and the output shaft of the reducer is connected to the gear. The motor drives the gear to rotate through the reducer, and the gear meshes with the rack, the rack and pinion guide composite, or the rack in three phases.

[0016] By adopting the above technical solution, the gear of the drive device can drive the rack or rack guide rail composite or rack three to slide, transforming the helical motion of the gear into the linear motion of the rack or rack guide rail composite or rack three.

[0017] Preferably, the slider or open linear bearing is provided with a slider fixing hole, and the drive seat is provided with a drive seat fixing hole. The drive seat fixing hole is provided in correspondence with the slider or open linear bearing fixing hole, so as to fix the drive seat on the slider or open linear bearing.

[0018] By adopting the above technical solution, the slider or open linear bearing can support the drive seat.

[0019] Preferably, the support frame includes a top plate, a vertical plate, and a bottom plate, with the top plate having an end face one and an end face two. The slider or open linear bearing is fixed to the top plate, the bottom plate is mounted on the vehicle body, and the load-bearing box assembly slides back and forth on both sides of the vertical plate through the elongated opening.

[0020] By adopting the above technical solution, the slider or open linear bearing is fixed on the top plate, and the weight borne by the slider or open linear bearing can be transferred to the top plate of the support frame. The long strip opening at the bottom of the load-bearing box passes through the vertical plate of the support frame, and the bottom plate supports the entire sliding box. It is not necessary to disassemble the vehicle chassis. The bottom plate of the support frame is directly fixed to the vehicle body, and the entire sliding box is suspended at the opening of the vehicle. The support frame transfers the weight of the sliding box to the vehicle body.

[0021] Preferably, the carrier box assembly includes a carrier box body, a load-bearing inspection plate, a load-bearing plate, and flanges one and two, or flanges three and four. A load-bearing inspection plate is installed at one end of the carrier box body along its length, and a load-bearing plate is installed at the other end. One end of the guide rail, rack and pinion guide rail composite, or linear optical axis is fixed to the load-bearing inspection plate via flange one or flange three, and the other end is fixed to the load-bearing plate via flange two or flange four.

[0022] By adopting the above technical solution, flange one and flange two, or flange three and flange four, can bear the weight of the guide rail or rack and pinion guide composite or linear optical axis, and transfer the weight to the load-bearing inspection plate and the load-bearing plate. In addition, the guide rail or rack and pinion guide composite or linear optical axis can drive the load-bearing box assembly to reciprocate. When the sliding box slides out, the sliding process ends when flange one touches end face one. When the sliding box retracts, the retraction process ends when flange two or flange four touches end face two.

[0023] Preferably, the load-bearing maintenance plate is provided with a flange fixing hole and a guide rail connection hole. Flange 1 or Flange 3 is fixed to the load-bearing maintenance plate via the flange fixing hole. Flange 1 or Flange 3 has a support opening that allows the guide rail, rack and pinion guide composite, or linear optical axis to pass through the guide rail support opening 1 or optical axis support opening 3. One end of the guide rail or linear optical axis passes through a specific flange (flange 1 or flange 3) and then connects to another key component—the guide rail connection hole 1—through a corresponding fixing hole (combined guide rail fixing hole 1, composite fixing hole 3, or linear optical axis fixing hole 5). Finally, this assembly is fixed to the load-bearing maintenance plate.

[0024] The load-bearing plate is provided with flange two fixing holes and guide rail connection holes two. Flange two or flange four is provided with guide rail support port two or optical axis support port four that allows the guide rail or the rack and pinion guide rail composite or linear optical axis combination to pass through. The other end of the guide rail or rack and pinion guide rail composite or linear optical axis passes through flange two or flange four and is fixed to the load-bearing plate through the combined guide rail fixing hole two or the composite fixing hole four or the linear optical axis fixing hole six and the guide rail connection hole two.

[0025] By adopting the above technical solution, one end of the guide rail or the rack and pinion guide rail composite or the linear optical axis can be fixed to the load-bearing maintenance plate through flange one or flange three, and the other end can be fixed to the load-bearing plate through flange two or flange four, which facilitates the load-bearing maintenance plate and the load-bearing plate to support the guide rail or the rack and pinion guide rail composite or the linear optical axis.

[0026] Preferably, the load-bearing maintenance plate is detachable.

[0027] By adopting the above technical solution, when a fault occurs inside the load-bearing box assembly, it can be repaired by disassembling the load-bearing inspection plate, thereby reducing maintenance costs.

[0028] Preferably, the carrier box assembly further includes a control component, which is disposed on the side wall inside the carrier box.

[0029] By adopting the above technical solution, when the two carrier box components move asynchronously, the control component can detect the corresponding information and report the detected information to the controller, which will then perform the corresponding operation.

[0030] By adopting the above technical solution, when the sliding box is retracted, the control component detects the vertical plate of the support frame, the retraction movement stops, and the sliding box is fully retracted.

[0031] In summary, this application includes at least one of the following beneficial technical effects:

[0032] 1. Integrating the sliding components, drive unit, and part of the support frame into the carrier box assembly can isolate the sliding components and drive unit from external influences, facilitate installation and disassembly, improve the appearance, and increase the interior space of the vehicle.

[0033] 2. There is no need to disassemble the vehicle chassis. The base plate of the support frame is directly fixed to the vehicle body, and the entire sliding box is suspended at the opening of the vehicle. The base plate of the support frame transfers the weight of the sliding box to the vehicle body.

[0034] 3. The load-bearing inspection plate on the load-bearing box assembly is removable. When a fault occurs inside the load-bearing box assembly, it can be repaired by removing the load-bearing inspection plate, thereby reducing maintenance costs. Attached Figure Description

Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0054] Reference Figure 1-2As can be seen, when the vehicle is stationary, the sliding box 1 slides completely out from the opening on the vehicle body 27, increasing the usable space inside the vehicle body 27. After retracting, the sliding box 1 is flush with the appearance of the vehicle body 27, without affecting the overall aesthetic effect. The carrier box assembly 24 is installed on the lower part of the side wall of the sliding box.

The load-bearing maintenance plate 14 is provided with a flange fixing hole 19 and a guide rail connection hole 21. The flange 6A or flange 6C is fixed to the load-bearing maintenance plate 14 through the flange fixing hole 19. The flange 6A or flange 6C is provided with a guide rail support port 601 or optical axis support port 601C that allows the guide rail 5 or rack and pinion guide rail composite 5B or linear optical axis 263 to pass through. One end of the guide rail 5 or rack and pinion guide rail composite 5B or linear optical axis 263 passes through the flange 6A or flange 6C and is fixed to the load-bearing maintenance plate 14 through the combined guide rail fixing hole 501A or composite fixing hole 501B or linear optical axis fixing hole 501C and the guide rail connection hole 21.

[0066] Reference Figure 13 The diagram shows the internal structure of the vehicle body sliding system fully extended, as shown in direction A.

[0067] Reference Figure 14 The diagram shows the internal structure of the vehicle body sliding system when fully retracted, as shown in direction B.

[0068] Reference Figure 15 , Figure 7 The diagram shows the sliding system of the vehicle body. The motor 9 of the drive unit 25 drives the gear 13 to rotate through the reducer 10. The gear 13 meshes with the rack 8 or rack 8B or rack 3 8C of the rack guide rail combined sliding assembly 26A and the rack guide rail composite sliding assembly 26C, converting the helical motion of the gear 13 into the linear motion of the rack 8 or rack 8B or rack 3 8C. The gear 13 drives the guide rail 5 or the rack guide rail composite 5B or the linear optical axis 263 to slide out. The guide rail 5 or the rack guide rail composite 5B or the linear optical axis 263 drives the carrier box assembly 24 to slide out. The carrier box assembly 24 drives the sliding box 1 to slide out. When the flange 6A touches the end face 304A or the flange 3 6C touches the end face 304A, the sliding motion stops and the sliding box 1 slides out completely.

[0069] The sliding box 1 slides out through the long opening 16 at the bottom of the carrying box 2. After the sliding box 1 slides out, the carrying box 2 bears the weight of the sliding box 1 and transfers the weight to the guide rail 5 or rack and pinion guide rail composite 5B or linear optical axis 263. The guide rail 5 or rack and pinion guide rail composite 5B or linear optical axis 263 transfers the weight to the slider 4 or open linear bearing 261. The slider 4 or open linear bearing 261 transfers the weight to the support frame 3. The support frame 3 transfers the entire weight of the sliding box 1 to the car body 27.

[0070] Reference Figure 16 , Figure 7 The diagram shows the retraction of the vehicle body sliding system. The motor 9 of the drive unit 25 drives the gear 13 to rotate in the opposite direction via the reducer 10. The gear 13 meshes with rack 8 or guide rail rack 8B or rack 8C, converting the helical motion of the gear 13 into linear motion. The gear 13 drives the guide rail 5 or rack-guide rail composite 5B or linear optical axis 263 to retract. The guide rail 55 or rack-guide rail composite 5B or linear optical axis 263 drives the carrier box assembly 24 to retract. The carrier box assembly 24 drives the sliding body 1 to retract. When flange 6B touches end face 304B or flange 6D touches end face 304B, the retraction stops, and the sliding body 1 is fully retracted. When the two carrier box assemblies 24 move asynchronously, the control component 12 can detect the corresponding information and report it to the controller, which then performs the corresponding operation.

[0071] The load-bearing inspection plate 14 is detachable.
