Description

Technical Field

[0001] This invention relates to three self-driven rack and pinion guide modules and their application in vehicle body sliding systems, belonging to the fields of mechanical motion and vehicle space expansion technology. Background Technology

[0002] Existing mechanical transmissions and modules require external drives for transmission and movement. DE102019A131278A1 discloses a gear and rack guide rail transmission module that requires an external drive to move. External drives occupy a large space and are inconvenient to install.

[0003] US202117A408020A discloses a vehicle sliding device located on both sides of a sliding box. 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.

[0004] In response to the aforementioned technical deficiencies, the inventors believe that existing mechanical transmissions and modules require an external driving source, and when used in vehicle sliding systems, the sliding mechanism is quite large, resulting in complex installation and a large space occupation. Summary of the Invention

[0005] To address the issues of complex installation and large space occupation in mechanical transmission, modules, and vehicle sliding systems, this invention provides three self-driven rack and pinion guide modules and their application in vehicle body sliding systems. The three self-driven rack and pinion guide modules are: an interlaced module, an intersecting module, and a parallel module. All three modules have their own drive source, occupy a small volume, and are easy to install. In use, simply connecting them to power directly converts helical motion into linear motion of the rack and pinion guide, enabling high-precision linear motion even under high loads.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Optionally, a self-driven rack and pinion guide interleaved module includes a module housing, an interleaved gear assembly, an interleaved drive box, an interleaved gear box, a motor, slider one, slider two, slider three, slider four, guide rail one, guide rail two, and a combined load-bearing rack. The module housing contains the interleaved drive box and the interleaved gear box. The interleaved drive box contains the motor, and the interleaved gear box contains the interleaved gear assembly. Guide rail one has guide rail hole one, and guide rail two has guide rail hole two. The vertical plate of the combined load-bearing rack has guide rail fixing holes corresponding to guide rail hole one and guide rail hole two, fixing guide rail one and guide rail two to both sides of the vertical plate of the combined load-bearing rack. The bottom of the combined load-bearing rack has a rack. Slider one and slider two are slidably connected to guide rail one, and slider three and slider four are fixedly slidably connected to guide rail two. Slider one and slider two are fixed to one side of the module housing, and slider three and slider four are fixed to the other side of the module housing.

[0008] By adopting the above technical solution, the interleaved drive box and interleaved gear box are integrated in the module housing. They have their own drive source, and when powered on, the rack can perform high-load and high-precision linear motion on the slider. This enables the rack to perform linear synchronous reciprocating linear motion with its own drive. It is easy to install and disassemble, and the overall appearance is aesthetically pleasing.

[0009] Optionally, the interleaved drive box and the interleaved gear box are separated by a partition, and the partition is provided with a drive hole.

[0010] By adopting the above technical solution, the motor can be driven by a pair of interlaced gear assemblies in an interlaced gearbox through a drive hole.

[0011] Optionally, the interleaved gear assembly includes an output shaft, a worm, a worm wheel, an interleaved output gear, a snap ring one and a snap ring two, and bearings one, two, three, and four. The worm wheel and the interleaved output gear are fixed on the output shaft. The interleaved output gear is fixed by the snap ring one, and the worm wheel is fixed by the snap ring two. Bearings one and two are provided on both sides of the output shaft, and bearings three and four are fixed on both sides of the worm. The output shaft of the motor is connected to the worm through the drive hole one. The worm and the worm wheel mesh interleaved, and the interleaved output gear meshes with the rack, converting the helical motion into linear motion.

[0012] By adopting the above technical solution, the motor's output shaft is connected to the worm gear through drive hole one, driving the worm gear to rotate. The worm gear drives the worm wheel for speed change and deceleration. The worm wheel synchronously drives the interleaved output gear to rotate. The interleaved output gear meshes with the rack, converting the helical motion into the linear motion of the rack. Bearings one and two support the output shaft, reducing friction during operation. Bearings three and four support the worm gear, reducing friction during operation.

[0013] Optionally, the module housing is provided with bearing cover one, bearing cover two, and bearing cover three. Bearing cover one and bearing one are fitted together at one bearing hole, bearing cover two and bearing two are fitted together at the second bearing hole, and bearing cover three and bearing three are fitted together at the third bearing hole.

[0014] By adopting the above technical solution, bearing cover one and bearing one, together with the corresponding bearing cover two and bearing two, provide support for the output shaft, facilitating the installation and maintenance of the output shaft, worm gear, and interleaved output gears. Bearing cover three and bearing three provide support for the worm gear, facilitating its installation and maintenance. Bearing four provides support for the motor and worm gear, facilitating motor installation.

[0015] Optionally, a gearbox grease nipple is provided at one end of the outer side of the interleaved gearbox.

[0016] By adopting the above technical solution, the oil nozzle provides lubrication to the gears, reducing friction.

[0017] Optionally, a removable motor heat sink is provided on the side of the module housing near the interleaved drive box, and the motor heat sink has wiring holes for powering the motor.

[0018] By adopting the above technical solution, the motor's wires can pass through the wire hole to supply power to the motor, and the heat generated during the motor's operation can be dissipated through the motor heat sink cover. Furthermore, the motor heat sink cover is removable, making maintenance and installation convenient.

[0019] Optionally, a self-driven rack and pinion guide intersecting module includes a module housing, intersecting gear assembly, intersecting drive box, intersecting gearbox, slider one, slider two, slider three, slider four, guide rail one, guide rail two, and combined load-bearing rack. Unlike the self-driven rack and pinion guide intersecting module, the intersecting gear assembly replaces the intersecting gear assembly. The intersecting gear assembly includes an input bevel gear, output shaft one, output shaft two, output shaft three, output bevel gear, gear two, gear three, gear four, gear five, gear six, bearing five, bearing six, bearing seven, bearing eight, bearing nine, bearing ten, and retaining rings three, four, five, six, seven, and eight. The output shaft one is equipped with the output bevel gear and gear two, and bearings five and six are located at both ends. Retaining ring three engages the output bevel gear, and retaining ring four engages the gear two. The output shaft 2 is equipped with gear 3 and gear 4, and bearings 7 and 8 are located at both ends. A retaining ring 5 engages gear 3, and a retaining ring 6 engages gear 4. The output shaft 3 is equipped with gear 5 and gear 6, and bearings 9 and 10 are located at both ends. A retaining ring 7 engages gear 5, and a retaining ring 8 engages gear 6. The module housing is equipped with bearing covers 4, 5, 6, 7, 8, and 9, and bearing holes 4, 5, 6, 7, 8, and 9. Bearing 5 and bearing cover 4 are fitted together at bearing hole 4; bearing 8 and bearing cover 5 are fitted together at bearing hole 5; bearing 9 and bearing cover 6 are fitted together at bearing hole 6; bearing 6 and bearing cover 7 are fitted together at bearing hole 7; bearing 7 and bearing cover 8 are fitted together at bearing hole 8; and bearing 10 and bearing cover 9 are fitted together at bearing hole 9. The output shaft of the motor is connected and fixed to the input bevel gear through the drive hole 2 on the partition 2. The input bevel gear and the output bevel gear mesh with each other and change direction. Gear 2 meshes with gear 3, gear 4 meshes with gear 5, and gear 6 meshes with the rack.

[0020] By adopting the above technical solution, the motor is connected to the power supply through the wire hole. The output bevel gear on the motor output shaft drives the input bevel gear in the intersecting gearbox to rotate 90 degrees and decelerate through the second drive hole. The input bevel gear meshes with the output bevel gear, and the input bevel gear drives the output bevel gear to rotate. The output bevel gear and gear two are fixed on the first output shaft. The output bevel gear and gear two rotate synchronously. Gear two drives gear three to rotate. Gear three and gear four are fixed on the second output shaft. Gear three and four rotate synchronously. Gear four and gear five mesh. Gear five drives gear six, which is fixed on the third output shaft, to rotate. Gear six meshes with the rack, converting the helical motion into the linear motion of the rack.

[0021] Optionally, a self-driven rack and pinion guide parallel module includes a module housing, a parallel gear assembly, a parallel drive box, a parallel gear box, slider one, slider two, slider three, slider four, guide rail one, guide rail two, and a combined load-bearing rack. Unlike the self-driven rack and pinion guide intersecting module, the parallel gear box is L-shaped, and the parallel drive box is separated from the parallel gear box by an L-shaped partition three. The parallel gear assembly replaces the intersecting gear assembly. The parallel gear assembly differs from the intersecting gear assembly in that the parallel motor gear meshes parallel to the first parallel gear. The output shaft of the motor is connected and fixed to the parallel motor gear through a drive hole three on the partition three. In the self-driven rack and pinion guide intersecting module, the motor changes direction by meshing the input bevel gear with the output bevel gear, converting helical motion into linear motion. In the self-driven rack and pinion guide parallel module, the motor directly converts helical motion into linear motion by meshing the parallel motor gear with the first parallel gear.

[0022] By adopting the above technical solution, the motor is connected to the power supply through the wire hole. The parallel motor gear on the motor output shaft drives the parallel gear 1 inside the parallel gearbox to rotate through the drive hole 3. The parallel motor gear meshes with the parallel gear 1 in parallel. The parallel gear 1 drives the output shaft 1 to rotate. The output shaft 1 drives the gear 2 to rotate. The gear 2 and gear 3 mesh. The gear 3 drives the gear 4 fixed on the output shaft 2 to rotate. The gear 4 and gear 5 mesh. The gear 5 drives the gear 6 fixed on the output shaft 3 to rotate. The gear 6 meshes with the rack, directly converting the helical motion into the linear motion of the rack.

[0023] Optionally, the first guide rail, the second guide rail, and the combined load-bearing rack maintain a cantilever configuration when these three modules slide out and retract; the top of the combined load-bearing rack is provided with a combined load-bearing rack connection hole, which allows the object to be carried in the application scenario to be connected to the combined load-bearing rack through the combined load-bearing rack connection hole, depending on the application scenario.

[0024] By adopting the above technical solutions, guide rail one, guide rail two and combined load-bearing rack cantilever can increase the sliding length and do not require additional support within a certain range; depending on the application scenario, rack guide rail interlaced modules, intersecting modules or parallel modules can be fixed on different application scenario loads.

[0025] Optionally, a self-driven rack and pinion guide module vehicle body sliding system includes a self-driven rack and pinion guide interlaced module, intersecting module, or parallel module, a support frame, a carrier box, and a sliding box. The self-driven interlaced, intersecting, or parallel module is disposed inside the carrier box. The bottom of the module housing of the self-driven rack and pinion guide interlaced, intersecting, or parallel module has a bottom plate connection hole that is fixedly connected to the top plate of the support frame. The support frame includes a top plate, a bottom plate, and a vertical plate. The combined load-bearing rack is fixedly connected to the top of the carrier box. The self-driven rack and pinion guide interlaced, intersecting, or parallel module is arranged parallel to the carrier box on corresponding sides below the sliding box and moves synchronously. The carrier box is not visible from the outside. The bottom of the carrier box has an elongated opening. When the vehicle is stationary, the sliding box slides out completely from the opening on the vehicle body, increasing the usable space inside the vehicle. After the sliding box is retracted, it is flush with the exterior of the vehicle body and does not affect the overall aesthetic effect.

[0026] By adopting the above technical solution, the rack is fixedly connected to the top of the carrier box, and the module housing is fixed on the support frame. The rack can drive the carrier box to slide, achieving sliding out and retraction through the long opening. The rack guide rail carrier box with its own driven intersecting, parallel, or interlocking modules can bear the weight and achieve high-precision linear motion under high load. The self-driven intersecting, parallel, or interlocking modules of the rack guide rail are integrated into the carrier box, occupying little space, increasing the usable area inside the vehicle, and creating a neat and aesthetically pleasing appearance. Furthermore, the carrier box can isolate the self-driven intersecting, parallel, or interlocking modules of the rack guide rail from contact with the outside world, facilitating sealing and extending service life. In addition, the base plate supports the entire sliding box, eliminating the 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 support frame transfers the weight of the sliding box to the vehicle body.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. Three types of self-driven rack and pinion guide modules, with the power unit integrated inside the module housing, do not require external drive. After being powered on, the motor rotates forward and backward through the gears to drive the rack and pinion guide to make linear reciprocating motion. They occupy little space and are easy to install and disassemble.

[0029] 2. The three types of self-driven rack and pinion guide interlaced, intersecting, or parallel modules can withstand a certain amount of torque and achieve high-precision linear motion under high load conditions.

[0030] 3. A self-driven rack and pinion guide module vehicle body sliding system, wherein the carrier box can isolate the external influence on the self-driven rack and pinion guide interlaced, intersecting, or parallel modules, resulting in a neat and aesthetically pleasing appearance, and can increase the interior usable space of the vehicle.

[0031] 4. A self-driven rack and pinion guide module vehicle body sliding system that does not require disassembly of the lower chassis of the vehicle body, is easy to install and disassemble, and can be installed at the opening of the vehicle body by simply fixing the base plate of the support frame to the vehicle body.
