Description

Technical Field

[0001] This invention relates to the field of vehicle interior space expansion technology, and in particular to a lead screw motor-type vehicle body sliding system. Background Technology

[0002] Existing vehicles and motorhomes can be equipped with slide-out cabins to increase interior space. When in motion, the slide-out cabin's outer wall is flush with the exterior of the vehicle or trailer. When the vehicle stops, the slide-out cabin slides out from the vehicle's opening, thus increasing interior space.

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

[0004] Patent US202117408020A discloses a sliding device that is set on both sides of the sliding box. Due to the complexity of the mechanism used, the telescopic drive device is too tall, occupies a lot of 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 occupation in vehicle sliding mechanisms, this invention provides a screw motor-type vehicle sliding system that increases vehicle usable space and improves space utilization. Since the entire sliding mechanism inside the carrying box is integrated and connected to the support frame base plate, there is no need to disassemble the lower chassis of the vehicle body. Installation and disassembly are convenient; simply fix the base plate of the support frame to the vehicle body, and the entire sliding box can be placed at the opening of the vehicle body.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A ball screw motor type vehicle body sliding system includes a sliding body, a load-bearing plate, a support frame, a ball screw motor, a guide rail one, a guide rail two, a slider one, a slider two, a slider three, a slider four, and a load-bearing box. The sliding box is located at the opening of the vehicle body. Corresponding load-bearing boxes are located below the opposite side walls of the sliding box. The two load-bearing boxes have identical internal structures, are correspondingly positioned, and move synchronously. The load-bearing plate is fixed to the load-bearing box. The lead screw motor is fixed to the support frame, with both ends fixed to the load-bearing plate. Guide rail one and guide rail two are parallel vertically and fixed to the load-bearing box via the load-bearing plate. Slider one and slider three are slidably connected to guide rail one, and slider two and slider four are slidably connected to guide rail two. Slider one, slider two, slider three, and slider four are fixed to the support frame. The lead screw motor, guide rail one, guide rail two, slider one, slider two, slider three, slider four, load-bearing plate, and part of the support frame (excluding the base plate) are integrated inside the load-bearing box. The bottom of the load-bearing box has a long opening through which it slides back and forth on the lower end of the support frame.

[0009] By adopting the above technical solution, the lead screw motor can drive the carrier box to slide back and forth, realizing the sliding out and retraction of the carrier box. The lead screw motor, guide rail one, guide rail two, slider one, slider two, slider three, slider four, load-bearing plate, and part of the support frame (except for the base plate) are integrated and set inside the carrier box, which can isolate external influences, facilitate installation and disassembly, improve appearance, and increase the interior space of the vehicle. The long strip opening at the bottom of the carrier box slides out and retracts from the lower end of the support frame. The base plate supports the entire sliding out carrier box. It is not necessary to disassemble the vehicle chassis. The base plate of the support frame is directly fixed to the vehicle body, and the entire sliding out carrier box is suspended at the opening of the vehicle. The support frame transfers the weight of the sliding out carrier box to the vehicle body.

[0010] Preferably, the guide rail one and the guide rail two maintain a cantilever configuration when the sliding box is slid out and retracted by fixed slider one, slider two, slider three and slider four.

[0011] By adopting the above technical solution, the cantilever of guide rail one through slider one and slider three, and guide rail two through slider two and slider four, can increase the sliding length of the box and increase the usable space inside the vehicle, without the need for additional support.

[0012] Preferably, slider one and slider two are flush vertically, slider three and slider four are flush vertically, and slider one and slider three are arranged parallel to slider two and slider four.

[0013] By adopting the above technical solution, when guide rail one and guide rail two slide back and forth, the force is balanced, the operation is smooth, and the friction is small.

[0014] Preferably, the load-bearing plate is provided with a first fixed bracket and a second fixed bracket at both ends, and the two ends of the lead screw motor are fixed to the load-bearing plate through the first fixed bracket and the second fixed bracket.

[0015] By adopting the above technical solution, the load-bearing plate supports the threaded screw and ensures that the central axis of the threaded screw is always in a straight line. In addition, the motor on the screw motor drives the threaded screw to rotate, thereby causing the load-bearing plate to slide.

[0016] Preferably, the support frame includes an upper plate, a lower plate, a bottom plate, a motor support frame, and a reinforcing plate. The lead screw motor passes through the motor support frame and the reinforcing plate, and the motor of the lead screw motor is fixed on the motor support frame.

[0017] By adopting the above technical solution, the lead screw motor is fixed on the motor support frame, keeping the motor stationary, while the support frame supports the lead screw motor.

[0018] Preferably, slider one and slider three are fixed on the lower plate, and slider two and slider four are fixed on the upper plate.

[0019] By adopting the above technical solution, the slider remains stationary while the guide rail can slide along the slider.

[0020] Preferably, the base plate is fixed to the vehicle body.

[0021] By adopting the above technical solution, the weight borne by the support frame is transferred to the vehicle body through the base plate.

[0022] Preferably, the load-bearing plate, the load-bearing box, and the lead screw motor are parallel along the length direction.

[0023] By adopting the above technical solution, when the lead screw motor drives the load-bearing plate to move, and then drives the load-bearing box to slide back and forth, it can ensure that the force is balanced during the movement, the operation is smooth, and the friction is small.

[0024] Preferably, the carrier box is provided with a removable inspection panel on the side near the interior of the carriage.

[0025] By adopting the above technical solution, installation is convenient, and when a fault occurs inside the carrier box, it can be repaired by disassembling the inspection plate, thus reducing maintenance costs.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. The lead screw motor, guide rail 1, guide rail 2, slider 1, slider 2, slider 3, slider 4, load-bearing plate, and some support frames (except the base plate) are integrated into the load-bearing box, which can isolate the external influence, facilitate installation and disassembly, have an aesthetic appearance, and increase the interior space of the vehicle.

[0028] 2. Since the entire sliding mechanism inside the load cell is integrated and connected to the base plate of the support frame, it is not necessary to disassemble the lower chassis of the vehicle body. Installation and disassembly are convenient. Simply fix the base plate of the support frame to the vehicle body, and the entire sliding box can be set at the opening of the vehicle body. The support frame transfers the weight of the sliding box to the vehicle body.

[0029] 3. The inspection plate on the carrier box is removable. When a fault occurs inside the carrier box, it can be repaired by removing the inspection plate, thus reducing maintenance costs. Attached Figure Description

[0040] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. 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.

[0041] Reference Figure 1 , Figure 2 As shown: The sliding box 1 is located at the opening of the vehicle body 25. When the vehicle is stationary, the sliding box 1 slides out completely from the opening on the vehicle body 25, increasing the usable space inside the vehicle. After the sliding box 1 is retracted, it is flush with the appearance of the vehicle body 25 and does not affect the overall aesthetic effect.

[0042] Reference Figure 3 , Figure 4 As shown: A screw motor-type vehicle body sliding system includes a sliding body 1, a load-bearing plate 7, a support frame 3, a screw motor 4, guide rail 1 6a, guide rail 2 6b, slider 1 8a, slider 2 8b, slider 3 8c, slider 4 8d, and a load-bearing box 2. The sliding body 1 is made of aluminum alloy or other lightweight materials with low structural rigidity. Corresponding load-bearing boxes 2 are located below opposite side walls of the sliding body 1. The two load-bearing boxes 2 have identical internal structures, are correspondingly positioned, and move synchronously, bearing the weight of the sliding body 1. The screw motor 4, guide rail 1 6a, guide rail 2 6b, slider 1 8a, slider 2 8b, slider 3 8c, slider 4 8d, load-bearing plate 7, and part of the support frame 3 (excluding the base plate) are integrated inside the load-bearing box 2, saving space and facilitating quick installation and disassembly.

[0043] Reference Figure 5 , Figure 6As shown: The load-bearing plate 7 is fixed on the bearing box 2. Fixed brackets 4a and 4b are provided at both ends of the load-bearing plate 7. The support frame 3 includes an upper plate 3a, a lower plate 3b, a bottom plate 3c, a motor support frame 5a, and a reinforcing plate 5b. The lead screw motor 4 passes through the motor support frame 5a and the reinforcing plate 5b. The motor of the lead screw motor 4 is fixed on the motor support frame 5a, and both ends are fixed to the load-bearing plate 7 via fixed brackets 4a and 4b. The guide rails 6a and 6b are parallel vertically and fixed to the bearing box 2 via the load-bearing plate 7. The sliders 8a and 8c are slidably connected to the guide rail 6a, and the sliders 8b and 8d are slidably connected to the guide rail 6b. The sliders 8a and 8c are fixed on the lower plate 3b, and the sliders 8b and 8d are fixed on the upper plate 3a. The sliders 8a and 8b are flush, as are the sliders 8c and 8d. The sliders 8a and 8c are parallel to the sliders 8b and 8d. The guide rail 1, via sliders 1 and 3, and the guide rail 2, via sliders 2 and 4, drive the sliding box 1 to slide out and retract, maintaining a cantilevered configuration. The carrying box 2 has a removable inspection plate 203 on the side near the interior of the carriage. Removing the inspection plate 203 allows for installation and maintenance of the interior of the carrying box 2. The bottom of the carrying box 2 has a long opening 9 through which it slides back and forth on both sides of the support frame 3.

[0044] Reference Figure 7 As shown: When the lead screw motor type vehicle sliding system slides out, the motor on the lead screw motor drives the threaded lead screw to rotate, thereby driving the load-bearing box 2 and the load-bearing plate 7 to slide outward together through guide rail 1 6a and guide rail 2 6b. When the sliding box 1 slides to the set length, the sliding process ends. The support frame 3 remains stationary. After the sliding box 1 slides out, the load-bearing box 2 transfers the weight of the sliding box 1 to the load-bearing plate 7. The load-bearing plate 7 transfers the weight to the slider 1 8a, slider 2 8b, slider 3 8c, and slider 4 8d through guide rail 1 6a and guide rail 2 6b, and then to the support frame 3. Finally, the support frame 3 transfers the weight to the vehicle body 25.

[0045] Reference Figure 8 As shown: When the lead screw motor type vehicle sliding system retracts, the motor on the lead screw motor drives the threaded lead screw to rotate in the opposite direction, thereby driving the bearing box 2 and the load-bearing plate 7 to retract inward together through guide rail 1 6a and guide rail 2 6b. When the sliding box 1 and the vehicle body 25 are flush in appearance, the retraction process ends.
