[0002] A tractor refers to a vehicle equipped with traction power. With its own power system and a connecting device designed specifically for traction, it can easily pull objects lacking the ability to drive independently or requiring external force assistance. In the existing film and television shooting industry, using a tractor for shooting props and photographic tools can replace traditional manual handling, thereby reducing the labor intensity of porters. The existing tractor chassis layout structure mainly includes a frame, a traction auxiliary mechanism, a drive system, and a corresponding electronic control system. Among them, the traction auxiliary mechanism includes a corresponding shock absorption structure, such as shock absorption components like air suspensions. At the same time, with the popularization of electronic control, most of the existing tractor controls use electronic control systems. Compared with traditional mechanical control structures, the layout and connection of the entire structure are more concise when meeting basic driving, steering, and braking functions. In the existing tractor chassis layout structure, since the overall structure is fixedly connected during installation and layout, and due to the layout structure of the power device at the bottom of the vehicle, the replacement of the main power components is rather cumbersome during the entire process, making the entire process very inconvenient when the existing layout structure needs to be replaced and installed in case of corresponding situations.

Detailed implementation manners

[0024] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention and should not be construed as a limitation to the present invention.

[0025] In the description of the present invention, it should be understood that the meaning of "a plurality of" is two or more unless otherwise specifically defined.

[0026] Please refer to Figures 1 to 7 , the present invention provides an air suspension tractor chassis layout structure, a drive system and a method: including a driving chassis 101, a vehicle frame chassis 102 and a junction box 103, a movable bracket 104, a tipping frame 105, a pushing screw rod 106, a pushing motor 107, a supporting member and a regulating member. The supporting member includes a supporting bracket 201, a lifting screw rod 202, a friction pad 203 and a synchronous drive component. The regulating member includes a sliding bracket 301, a sliding screw rod 302, a sliding motor 303 and a tipping component. The synchronous drive component includes a synchronizing shaft 204, a synchronizing bevel gear 205, a driving bevel gear 206 and a synchronizing motor 207. The tipping component includes a sleeved gear 304, a driving toothed plate 305, a moving screw rod 306 and a moving motor 307. Through the foregoing solution, the problem that in the existing tractor chassis layout structure, since the overall structure is fixedly connected during installation and layout, and due to the layout structure of the power device at the bottom of the vehicle, the replacement process of the main power components is rather cumbersome, making the existing layout structure very inconvenient during the replacement and installation in case of corresponding situations is solved.

[0027] Furthermore, the two junction boxes 103 are respectively fixedly installed on one side of the driving chassis 101 and the vehicle frame chassis 102. The movable bracket 104 is slidably installed on the vehicle frame chassis 102. The flipping frame 105 is slidably connected to the driving chassis 101 and rotatably installed on the movable bracket 104. The pushing screw rod 106 is threadedly connected to the movable bracket 104 and rotatably installed on the vehicle frame chassis 102. The output shaft of the pushing motor 107 is connected to the pushing screw rod 106. The pushing motor 107 is fixedly installed on the vehicle frame chassis 102. The supporting member is connected to the vehicle frame chassis 102 for supporting and lifting the entire vehicle frame chassis 102. The regulating member is connected to the movable bracket 104 for correspondingly driving and regulating the flipping frame 105 and the driving chassis 101.

[0028] Specifically, a corresponding drive control mechanism is arranged inside the driving chassis 101. Corresponding drive wheels are arranged on the driving chassis 101. The arranged drive wheels are controlled by the drive control mechanism inside the driving chassis 101. Among them, all the wiring of the drive control mechanism is concentrated in the junction box 103 on the side of the driving chassis 101. The junction box 103 arranged on the vehicle frame chassis 102 is connected to the driving system of the vehicle body and is connected to the junction box 103 on the side of the driving chassis 101 through corresponding wiring. During actual use, the user can externally place the wiring and then protect it by arranging a corresponding housing. At the same time, an internal wiring structure can also be opened according to the actual situation to avoid the wires being exposed outside. By arranging the two junction boxes 103, the driving system can be connected to the drive control mechanism inside the driving chassis 101. Then, during actual operation, the user can drive and control the vehicle body through the arranged driving system. In this solution, the drive control mechanism arranged inside the driving chassis 101 can steer by controlling the differential speed of the two side wheels. The essence of the differential steering technology lies in that by precisely controlling the rotational speed difference between the left and right wheels, even in the case of no response from the steering wheels or non-synchronous rotation, the stable rotation of the vehicle body can be ensured. When the vehicle turns, the traveling paths of the wheels present an arc shape. In order to compensate for the difference between the left and right wheels, the inner wheel needs to rotate slightly slower, while the outer wheel needs to rotate faster to fill the distance difference. This technology enables the vehicle to have higher flexibility in narrow spaces or complex terrains. Adopting differential steering can simplify the wheel installation structure on the driving chassis 101 and also improve the flexibility of the tractor. The movable support 104 cooperates with a chute provided at the bottom of the vehicle frame chassis 102. A cylindrical turning frame 105 is rotatably arranged inside the movable support 104. The turning frame 105 is connected to the driving chassis 101 through the regulating member. At the same time, a threaded hole matching the pushing screw rod 106 is provided on a plate member connecting the side of the movable support 104 to the vehicle frame chassis 102. The pushing screw rod 106 is driven by the pushing motor 107, so that it is convenient for the user to drive the movable support 104 by the pushing motor 107 in cooperation with the pushing screw rod 106. In this way, the entire driving chassis 101 can be moved out by the movement of the movable support 104 and the driving of the driving chassis 101 by the regulating member. When it is necessary to inspect and view the chassis of the vehicle body, first remove all the wiring installed on the two junction boxes 103 of the driving chassis 101 and the vehicle frame chassis 102. Then, lift the vehicle frame chassis 102 by the supporting member. After the vehicle frame chassis 102 is lifted, drive the movable support 104 to move by the pushing motor 107 in cooperation with the pushing screw rod 106, so that the movable support 104 moves to the side of the vehicle frame chassis 102. After the movable support 104 is adjusted, drive the driving chassis 101 to move on the movable support 104 through the regulating member, so as to move out the driving chassis 101 for inspection and view. At the same time, the user can also flip the driving chassis 101 through the regulating member according to the actual situation. Thus, through the re-layout design of the existing vehicle bottom driving structure, the operator can quickly and conveniently install the power driving structure of the vehicle body chassis according to the actual situation.

[0029] Further, the two supporting brackets 201 are respectively slidably installed on both sides of the vehicle frame chassis 102; the two lifting screw rods 202 are respectively threadedly connected to the two supporting brackets 201 and are rotatably installed on both sides of the vehicle frame chassis 102; the two friction pads 203 are respectively fixedly installed on the two supporting brackets 201; the synchronous driving component is connected to the vehicle frame chassis 102 and is used for synchronously driving the two lifting screw rods 202.

[0030] Further, the synchronous shaft 204 is rotatably installed on the vehicle frame chassis 102; the two synchronous bevel gears 205 are respectively fixedly sleeved on both sides of the synchronous shaft 204; the two driving bevel gears 206 are respectively meshed with the two synchronous bevel gears 205 and are respectively fixedly installed on the tops of the two lifting screw rods 202; the output shaft of the synchronous motor 207 is connected to the synchronous shaft 204, and the synchronous motor 207 is fixedly installed on one side of the vehicle frame chassis 102.

[0031] When this embodiment is in use, the lifting brackets 201 are installed on both sides of the frame chassis 102. Threaded holes matching the lifting lead screws 202 are provided on the plates of the lifting brackets 201 that cooperate with the internal guide grooves of the frame chassis 102. The driving bevel gears 206 are fixed to the tops of the two lifting lead screws 202. The two driving bevel gears 206 are correspondingly matched with the two synchronous bevel gears 205 fixedly sleeved on the synchronous shaft 204. The synchronous bevel gears 205 provided on the two synchronous shafts 204 can adjust the transmission direction of the two driving bevel gears 206 by changing the matching positions. In this solution, the two synchronous bevel gears 205 need to drive the two driving bevel gears 206 to ensure consistent steering, and then synchronously drive the two lifting lead screws 202 on both sides. The synchronous shaft 204 is driven by the synchronous motor 207. The synchronous motor 207 drives the synchronous shaft 204 to rotate, and then the two synchronous bevel gears 205 fixedly sleeved on the synchronous shaft 204 drive the two driving bevel gears 206 and the lifting lead screws 202 to rotate. When the two lifting lead screws 202 on both sides rotate, the two lifting brackets 201 can slide on the frame chassis 102, thereby supporting and jacking up the entire vehicle body. When jacking up, the lifting brackets 201 can ensure stable support through the friction pads 203 fixedly installed at the bottom.

[0032] Furthermore, the sliding bracket 301 is slidably connected to the flipping frame 105 and fixedly installed on one side of the driving chassis 101; the sliding lead screw 302 is threadedly connected to the sliding bracket 301 and rotatably installed on one side of the flipping frame 105; the output shaft of the sliding motor 303 is connected to the sliding lead screw 302, and the sliding motor 303 is fixedly installed on one side of the flipping frame 105; the flipping component is connected to the flipping frame 105 and is used to drive the flipping frame 105 to rotate.

[0033] Furthermore, the sleeved gear 304 is fixedly installed on one side of the flipping frame 105; the driving toothed plate 305 is meshed with the sleeved gear 304 and slidably installed on one side of the movable bracket 104; the output shaft of the moving motor 307 is connected to the moving lead screw 306, and the moving motor 307 is fixedly installed on one side of the movable bracket 104.

[0034] When in use, the sliding bracket 301 cooperates with the guide groove provided inside the flipping frame 105. The sliding bracket 301 is fixedly arranged on the side of the driving chassis 101. A threaded hole for cooperating with the sliding lead screw 302 is provided on the sliding bracket 301. The sliding lead screw 302 is driven by the sliding motor 303, so as to drive the sliding bracket 301 and the driving chassis 101 through the cooperation of the sliding motor 303 and the sliding lead screw 302. The sleeved gear 304 is fixedly arranged at the side end of the flipping frame 105. The driving toothed plate 305 cooperates with the connecting bracket arranged on the back side of the movable bracket 104. A threaded hole for cooperating with the moving lead screw 306 is provided on the driving toothed plate 305. The moving lead screw 306 is driven by the moving motor 307, so as to drive the sleeved gear 304 and the flipping frame 105 to rotate by driving the driving toothed plate 305. After the movable bracket 104 moves to the side of the vehicle frame chassis 102, the sliding motor 303 can cooperate with the sliding lead screw 302 to drive the sliding bracket 301 and the driving chassis 101, and then completely move the driving chassis 101 out from the side of the vehicle frame chassis 102, so that the surface of the driving chassis 101 will not be blocked by the vehicle frame chassis 102, which is convenient for the user to directly maintain the components on the driving chassis 101. It should be noted that before the movable bracket 104 moves, the entire vehicle chassis will be lifted under the action of the supporting member. Therefore, the driving chassis 101 can be directly moved to the corresponding side of the vehicle frame chassis 102 in a suspended state. At the same time, after the driving chassis 101 is completely moved out, the moving motor 307 can cooperate with the moving lead screw 306 to drive the driving toothed plate 305, and then drive the sleeved gear 304 and the flipping frame 105 to rotate through the cooperation of the driving toothed plate 305. In order to avoid interference between the driving toothed plate 305 and the plate structure during the movement, a side through groove is provided at the corresponding position of the vehicle frame chassis 102. At the same time, since the entire supporting member is in a lifted state, the corresponding plate will not affect the movement of the driving toothed plate 305 after it moves down, which is convenient for the user to install the driving chassis 101.

[0035] Preferably, the installation assembly provided by the present invention further includes an extended support frame 401, a pulley support plate 402, an exhibition lead screw 403 and an exhibition motor 404.

[0036] Further, the two extension support frames 401 are respectively slidably mounted on the two support frames 201; a pulley support plate 402 is fixedly mounted at the bottom of each extension support frame 401; the two exhibition lead screws 403 are respectively threadedly connected to the two extension support frames 401 and are respectively rotatably mounted on the two support frames 201; the output shafts of the two exhibition motors 404 are respectively connected to the two exhibition lead screws 403, and the two exhibition motors 404 are respectively fixedly mounted on the two support frames 201.

[0037] During the use of this embodiment, an extension support frame 401 is slidably arranged on each support frame 201, a pulley support plate 402 is fixedly mounted at the bottom of each extension support frame 401, multiple pulley shafts are arranged at the bottom of the pulley support plate 402, the exhibition lead screw 403 is matched with a threaded hole on the side plate member of the extension support frame 401, and the exhibition lead screw 403 is driven by the exhibition motor 404. Since there may be a slight shift in the balance center of gravity during the entire vehicle frame support after the driving chassis 101 is laterally displaced and unfolded, after the support is carried out, the extension support frame 401 on the support frame 201 can move out from the side of the support frame 201 under the cooperation of the exhibition motor 404 and the exhibition lead screw 403. When the extension support frame 401 moves, the pulley support plate 402 can ensure the stability of the movement of the extension support frame 401, and the friction pad 203 arranged at the bottom of the support frame 201 can ensure the stability of the entire support position. In this way, through the expansion of the support structure, the support stability of the support structure can be ensured after the subsequent driving chassis 101 is moved out. After the operation is completed, the extension support frame 401 can be moved back, so that the vehicle body will not be affected by the support structure during normal operation.

[0038] Please refer to Figure 8 , an air suspension tractor driving system, applied to the air suspension tractor chassis layout structure, characterized by comprising a control command issuing module 1, a scheme setting module 2, a motor parameter acquisition module 3 and an execution module 4. The control command issuing module 1 is connected to the execution module 4, the scheme setting module 2 is connected to the execution module 4, and the execution module 4 is connected to the motor parameter acquisition module 3; The control command issuing module 1 is used for generating and outputting operation commands; The scheme setting module 2 is used for pre-setting the driving system layout scheme for the chassis to unfold and fold; The motor parameter acquisition module 3 is used for monitoring the operating parameters of all motors; The execution module 4 executes the drive system layout plan in the plan setting module 2 based on the operation instruction of the control instruction issuing module 1 and the real-time operation parameters of the motor obtained by the motor parameter acquisition module 3; Specifically, the control instruction issuing module 1 is mainly used to generate and output two instructions for the deployment and retraction of the vehicle chassis. Secondly, the user can also output the corresponding chassis flipping instruction according to the actual situation. The plan setting module 2 is used to preset the drive system layout plan for the deployment and retraction of the chassis. The corresponding drive system layout plan mainly includes controlling the driving sequence of each motor and controlling the operation parameters of each motor; The motor parameter acquisition module 3 is used to feedback the real-time operation parameters of each motor to facilitate the better implementation of the drive system layout plan set by the plan setting module 2; Among them, when the plan setting module 2 receives the instruction to deploy the vehicle chassis, the plan setting module 2 will call out the preset drive system layout plan for chassis deployment; The above drive system layout plan for chassis deployment mainly includes: First, control the synchronous motor 207 to work. Through the monitoring and feedback of the operation parameters of the synchronous motor 207 by the motor parameter acquisition module 3, the supporting brackets 201 on both sides can lift the entire vehicle body. The lifting height can be calculated and judged through the rotational operation parameters of the synchronous motor 207; After the supporting bracket 201 is lifted, control the two exhibition motors 404 to expand the extension support frames 401 provided on the two supporting brackets 201, and then control the pushing motor to drive the movable bracket 104 to move on the frame chassis 102; After the frame chassis 102 moves a set distance, the drive chassis 101 can be moved out by controlling the sliding motor 303 in cooperation with the sliding lead screw 302 and the sliding bracket 301, thereby completing the expansion of the frame chassis 102 structure; At the same time, the drive system layout plan for chassis retraction mainly includes: First, control the sliding motor 303 and the pushing motor 107 to move the drive chassis 101 and the movable bracket 104 back to their original positions in sequence, then control the exhibition motor 404 to retract the extension support frame on the supporting bracket 201, and finally control the synchronous motor 207 to retract the supporting bracket 201; When the user issues a flipping instruction through the manipulation instruction issuing module 1, a judgment unit is provided inside the execution module 4. When receiving the flipping instruction, it is necessary to judge whether the layout plan of the chassis deployment drive system has been completed. Only after the implementation of the chassis deployment drive system layout plan can the flipping instruction be implemented, so as to avoid unreasonable manipulation of the corresponding structure due to the user's misoperation, resulting in situations such as bumps.

[0039] Please refer to Figure 9 , a driving method for the layout of an air suspension tractor chassis, adopting the above-mentioned air suspension tractor chassis layout structure, including the following steps: S1: Remove all the wiring installed on the two junction boxes 103 of the drive chassis 101 and the frame chassis 102; S2: Lift the frame chassis 102 through the support member; Specifically, the lifting brackets 201 are installed on both sides of the frame chassis 102. Threaded holes matching the lifting screw rods 202 are provided on the plates of the lifting brackets 201 that cooperate with the internal guide grooves of the frame chassis 102. The two driving bevel gears 206 are fixed to the tops of the two lifting screw rods 202. The two driving bevel gears 206 are correspondingly matched with the two synchronous bevel gears 205 fixedly sleeved on the synchronous shaft 204. The synchronous bevel gears 205 provided on the two synchronous shafts 204 can adjust the transmission direction of the two driving bevel gears 206 by changing the mating position. In this solution, the two synchronous bevel gears 205 need to drive the two driving bevel gears 206 to ensure the same steering, and then synchronously drive the two lifting screw rods 202 on both sides. The synchronous shaft 204 is driven by the synchronous motor 207; Drive the synchronous shaft 204 to rotate through the synchronous motor 207, and then drive the two driving bevel gears 206 and the lifting screw rods 202 to rotate through the two synchronous bevel gears 205 fixedly sleeved on the synchronous shaft 204. When the two lifting screw rods 202 on both sides rotate, the two lifting brackets 201 can slide on the frame chassis 102, thereby supporting and lifting the entire vehicle body. When lifting, the lifting brackets 201 can ensure the stability of the support through the friction pads 203 fixedly installed at the bottom.

[0040] S3: After the frame chassis 102 is lifted, drive the movable bracket 104 to move through the push-out motor 107 and the push-out screw rod 106, so that the movable bracket 104 moves to the side of the frame chassis 102; S4: After the adjustment of the movable support 104 is completed, the driving chassis 101 is driven to move on the movable support 104 through the regulating member, and then the driving chassis 101 is moved out for inspection. At the same time, the user can also flip the driving chassis 101 through the regulating member according to the actual situation. Specifically, the movable support 104 is matched with the chute provided at the bottom of the vehicle frame chassis 102. A cylindrical flipping frame 105 is rotatably arranged inside the movable support 104. The flipping frame 105 is connected to the driving chassis 101 through the regulating member. At the same time, a threaded hole matching the pushing screw rod 106 is provided on the plate member connecting the side of the movable support 104 to the vehicle frame chassis 102.
