Description

Technical Field

[0001] This invention relates to the field of automotive repair equipment technology, and in particular to a vehicle-mounted mobile automotive repair station and its usage method. Background Technology

[0002] Currently, most car breakdowns are not caused by very serious malfunctions, with tire blowouts accounting for a significant proportion. When a car breaks down, a tow truck is often used to transport it to a repair shop. This not only incurs substantial costs, increasing the burden on the car owner, but also hinders the car from receiving prompt repairs, wasting the owner's valuable time.

[0003] For example, the invention disclosed in announcement number CN106274628B is a vehicle-mounted mobile auto repair station and its system. Its characteristic is the high integration of repair tools and equipment needed for most automotive malfunctions within the vehicle compartment, including both fixed and mobile repair tools; such as a sliding balancer, a vertical tool rack, a vacuum pump, a power distribution box, power and gas transmission equipment, a power inverter, an air compressor, and an automatic transmission oil exchanger; as well as a vehicle-mounted four-wheel alignment system, an exhaust emission analyzer, a two-ton jack, a manual oil pump, a CD player, several three-ton supports, a tire changer foot pedal controller, a tire changer, a front wheel turntable, and a tire expander. Its advantages are: a scientifically compact structure, full utilization of space, strong mobility, and integration with the mobile internet, facilitating on-site repair and rescue, enabling rapid repair of malfunctioning vehicles, saving car owners time and money, and making it particularly practical for remote areas far from auto repair shops, thus possessing significant promotional value.

[0004] The above technical solution still has some shortcomings in its use:

[0005] 1. During the use of the above technical solution, it is necessary to manually move the three-ton support, two-ton jack and tire changer and other related equipment used to support and disassemble the car from the truck bed. However, the weight of the related equipment is very heavy, so it is difficult to move, which not only affects the efficiency of car maintenance, but also easily causes injury to maintenance personnel during the moving process.

[0006] 2. The above technical solution has a single function. When maintenance is carried out in rainy or snowy weather, the maintenance personnel need to endure the rain and snow. Moreover, when maintaining a car in such weather, the internal mechanical parts and related components of the car are prone to getting damp.

[0007] 3. Due to insufficient lighting inside the carriage, the interior is relatively humid. If maintenance equipment is left inside for an extended period of time, it is prone to moisture damage.

[0008] To address the aforementioned problems, this invention proposes a vehicle-mounted mobile auto repair station and its usage method. Summary of the Invention

[0009] The purpose of this invention is to solve the shortcomings of existing technologies, such as the difficulty in transporting repair equipment, the inability to carry out repair work normally in rainy or snowy weather, and the easy for repair equipment to get damp in the vehicle compartment. Therefore, this invention proposes a vehicle-mounted mobile auto repair station and its usage method.

[0010] To achieve the above objectives, the present invention adopts the following technical solution:

[0011] A vehicle-mounted mobile auto repair station includes a cargo box bolted to the top of a truck bed. A placement plate and a sliding plate are slidably connected inside the cargo box, with the placement plate positioned above the sliding plate. Multiple pulleys are provided at the bottom of the placement plate, contacting the top of the sliding plate. Multiple toolboxes are bolted to both sides of the top of the placement plate. Corresponding auto repair instruments are placed on the top of the placement plate. A lifting structure is located below the sliding plate and slides along the bottom inner wall of the cargo box. Two doors are hinged to one side of the cargo box for closing it.

[0012] The shielding structure is installed on both sides of the carriage to protect maintenance personnel and those being repaired from rain and snow.

[0013] The control structure, located on top of the sliding plate, is used to control the raising and lowering of the lifting structure, thus enabling the lifting structure to be stored and retrieved.

[0014] In one possible design, the shielding structure includes L-shaped rotating flaps rotatably connected to both sides of the carriage. A protective box is located on the top of the carriage, containing a dual-axis cylinder. The two output shafts of the dual-axis cylinder extend to the outside of the protective box. Bases are welded to the adjacent sides of the two L-shaped rotating flaps, and rotating plates are rotatably connected to each of the two bases. The adjacent ends of the two rotating plates are rotatably connected to the two output shafts of the dual-axis cylinder. A first magnetic ring is bolted to the bottom of the protective box, and the first magnetic ring is used to increase the connection between the steel wire rope and the carriage. The connection between the wire rope and the carriage is such that two guide rods are fixed to the bottom of the wire rope by bolts, and the bottom ends of the guide rods slide into the carriage, with a sealed sliding between the guide rods and the carriage. When the dual-shaft cylinder is activated, the two output shafts of the dual-shaft cylinder retract, and through the cooperation of the base and the rotating plate, drive the two L-shaped rotating flaps to rotate 90°. At this time, the L-shaped rotating flaps unfold, which can expose the relevant maintenance instruments and toolboxes in the carriage for easy use by maintenance personnel. The vehicle to be repaired is located directly below the L-shaped rotating flaps, and through the cooperation of the L-shaped rotating flaps and the rain shield, sunshade can also be provided, making it easier for maintenance personnel to work.

[0015] In one possible design, the control structure includes two rotating shafts rotatably connected to the top of a sliding plate via support plates. Two first electromagnets are located on both sides of the bottom of the sliding plate. Multiple steel wire ropes are attached to the top of each of the first electromagnets, with the tips of the steel wire ropes extending above the sliding plate and fixedly connected to the outer wall of the rotating shafts. Guide rollers are rotatably connected to both sides of the top of the sliding plate via support plates, and the two guide rollers guide the multiple steel wire ropes on the two first electromagnets. A worm gear is fixed to one end of each of the two rotating shafts. A drive motor is bolted to the top of the sliding plate, and the output shaft of the drive motor passes through… A worm gear is fixed to the sliding plate via a coupling, and the worm gear meshes with two worm wheels. Storage slots are provided on both sides of the bottom of the sliding plate, and support legs for supporting the sliding plate are rotatably connected within these slots. A drive motor drives the worm gear to rotate, which in turn drives two rotating shafts to rotate in opposite directions via the two worm wheels. With the steel wire rope slack, the first electromagnet places the lifting structure on the ground. Then, the first electromagnet is de-energized, releasing its magnetic attraction to the lifting plate, thus controlling the lifting and lowering of the structure. This facilitates automatic removal and storage of the lifting structure later, eliminating the need for manual operation, improving maintenance efficiency, and preventing injuries to maintenance personnel during handling.

[0016] In one possible design, the lifting structure includes two movable bases and two connecting rods. The two ends of the connecting rods are welded to the adjacent sides of the two movable bases. Each of the two movable bases has multiple casters at its bottom. Each of the two movable bases has a lifting plate for lifting the vehicle. Two first bidirectional lead screws are rotatably connected within each of the two movable bases. The outer walls of each of the two first bidirectional lead screws are threaded with two sliding seats. The two sliding seats located on the same first bidirectional lead screw are respectively located on the positive and negative thread sections of the first bidirectional lead screw. Both sliding seats are rotatably connected to the top of a connecting rod, and the top of the connecting rod is rotatably connected to the bottom of the lifting plate. Two tire removal structures are provided on opposite sides of the two lifting plates, used to remove the car tires. The lifting structure is moved to a position below the car chassis, between the front and rear wheels. A motor drives a first double-acting screw to rotate, and multiple first double-acting screws rotate synchronously. The two sliding seats move towards each other, and the sliding seats lift the lifting plate upwards via the connecting rods, thereby lifting the entire car for easier maintenance by repair personnel.

[0017] In one possible design, the tire removal structure includes two connecting arms welded to one side of the lifting plate. One end of each connecting arm is slidably connected to a common sliding plate. A movable groove is provided on the side of the sliding plate away from the connecting arms. A second double-acting screw is rotatably connected within the movable groove, with one end of the second double-acting screw extending to the outside of the sliding plate. Two nut blocks, threadedly connected to the second double-acting screw, are slidably connected within the movable groove. The two nut blocks are located on the positive and negative thread sections of the second double-acting screw, respectively. A sliding sleeve is bolted to one side of each of the two nut blocks, and the sliding sleeve is slidably fitted onto the outer wall of the sliding plate. A tire clamp is provided on one side of the sliding sleeve, and the tire clamp is used to clamp the tire. The tire clamps are provided with anti-slip textures on their adjacent sides. Multiple telescopic rods are fixed to both sides of the nut block by bolts. The output shafts of the multiple telescopic rods pass through the sliding sleeve and are fixedly connected to the tire clamps. When it is necessary to remove the car tire, the tire clamps are stretched outward, the output shafts of the telescopic rods extend, and the two tire clamps are located on both sides of the tire. Then, the second double-acting screw is rotated, and the two nut blocks drive the two tire clamps through the sliding sleeve to complete the clamping of the tire. The maintenance personnel can remove the tire by taking out the appropriate wrench from the toolbox, and then pull the slide plate outward to remove the tire from the car. The tire can be easily removed without manual handling.

[0018] In one possible design, rain shields are slidably connected to the opposite sides of the two L-shaped rotating flaps, increasing the area covered by rain and snow. Bolts are threaded through the internal threads of the L-shaped rotating flaps, and these bolts can brake the rain shields. By loosening the bolts, the locking between the L-shaped rotating flaps and the rain shields is released, allowing the rain shields to be pulled out. This controls the area covered by the L-shaped rotating flaps and the rain shields, thus protecting maintenance personnel from rain and snow and making their work easier.

[0019] In one possible design, a locking pin slides through the placement plate, with an inclined surface on the side of the locking pin near the door. The top of the sliding plate has a groove that engages with the locking pin. In rainy or snowy weather, the locking pin is pulled upward to release the engagement between the locking pin and the groove. Thus, when the sliding plate moves the lifting structure out of the carriage, the toolbox remains inside the carriage, ensuring that maintenance personnel are not exposed to rain or snow when retrieving tools. Similarly, through the engagement of the locking pin and the groove, the sliding plate can move the placement plate out of the carriage, making it easy for maintenance personnel to retrieve the corresponding maintenance tools and allowing the relevant maintenance instruments on the placement plate to be exposed to sunlight, preventing them from getting damp.

[0020] In one possible design, the lifting plate has a sheet metal layer inside, and the first electromagnet is magnetically connected to the lifting plate through the sheet metal layer; and the magnetic attraction of the first electromagnet to the lifting plate is extremely strong, which can completely attract the lifting structure and is used to control the lifting and lowering of the lifting structure.

[0021] In one possible design, a second magnetic ring is fixedly embedded in the top inner wall of the latch, and a second electromagnet is fixedly embedded in the top of the placement plate. A repulsive force is generated between the second magnetic ring and the second electromagnet. The bottoms of the two guide rods are fixed to the same extrusion plate by bolts. A first metal contact piece is fixed to the top of the extrusion plate by bolts. A second metal contact piece is fixed to the top inner wall of the carriage by bolts, and the second metal contact piece cooperates with the first metal contact piece. Both the first and second metal contact pieces are electrically connected to the second electromagnet. The first and second metal contacts are respectively connected to the positive and negative terminals of the external power supply. The protective box rises under the action of the L-shaped rotating flap, and the pressing plate causes the first and second metal contacts to come into contact. At this time, the second electromagnet is energized and generates a repulsive force on the second magnetic ring, causing the locking pin to disengage from the slot. When the sliding plate moves the lifting structure out of the carriage later, it can prevent the placement plate and toolbox from being moved out of the carriage as well, ensuring that maintenance personnel can easily take out the corresponding maintenance tools from the toolbox under the cover of the L-shaped rotating flap and the rain shield.

[0022] This application discloses a method for using a vehicle-mounted mobile auto repair station, comprising the following steps:

[0023] S1. This repair station has two operating modes: rain / snow and sunny weather. When used in rain / snow, the dual-shaft cylinder is activated, and the two output shafts of the dual-shaft cylinder retract. Through the cooperation of the base and the rotating plate, the two L-shaped rotating flaps rotate 90°. At this time, the L-shaped rotating flaps unfold, which can expose the relevant repair instruments and toolboxes in the compartment for easy use by repair personnel. The vehicle to be repaired is located under the L-shaped rotating flaps. By loosening the bolts, the locking between the L-shaped rotating flaps and the rain shield can be released, and the rain shield can be pulled out to control the area of ​​rain and snow blocked by the L-shaped rotating flaps and the rain shield. Similarly, in summer, the L-shaped rotating flaps and the rain shield can also provide sunshade, making it easier for repair personnel to work.

[0024] S2. Additionally, when the two L-shaped rotating flaps rotate, the protective box rises under the action of the L-shaped rotating flaps, and the pressing plate causes the first metal contact piece to contact the second metal contact piece. At this time, the second electromagnet is energized, and the second electromagnet generates a repulsive force on the second magnetic ring, causing the locking pin to disengage from the slot. When the sliding plate moves the lifting structure out of the carriage later, it can prevent the placement plate and toolbox from being moved out of the carriage as well, ensuring that maintenance personnel can easily retrieve the corresponding maintenance tools from the toolbox under the cover of the L-shaped rotating flaps and the rain shield.

[0025] S3. When maintenance is carried out in normal weather, the sliding plate is pushed out of the carriage by a cylinder (or an electric slide rail, both of which are existing technologies and are not shown here, so we will not go into details). The locking pin is locked into the slot under its own weight. Therefore, the sliding plate moves the placement plate out through the locking pin. This not only makes it easy for maintenance personnel to take out the corresponding maintenance tools, but also allows the relevant maintenance instruments on the placement plate to be exposed to the sun and prevents them from getting damp.

[0026] S4. When the sliding plate moves the lifting structure out of the car body, the worm gear is driven to rotate by the drive motor. The worm gear drives two rotating shafts to rotate in opposite directions through two worm wheels. The first electromagnet places the lifting structure on the ground under the slack of the wire rope. Then the first electromagnet is de-energized, and the first electromagnet releases its magnetic attraction to the lifting plate (the lifting plate has a sheet metal layer, and the first electromagnet has a very strong magnetic attraction to the lifting plate, which can completely attract the lifting structure). The lifting structure is moved to the bottom of the car chassis and is located between the front and rear wheels. The first double-acting screw is driven to rotate by the motor, and multiple first double-acting screws rotate synchronously. The two sliding seats move in opposite directions. The sliding seats lift the lifting plate upward through the connecting rod to lift the entire car.

[0027] S5. When it is necessary to remove the car tire, pull the tire clamps outward, the output shaft of the telescopic rod extends, and the two tire clamps are located on both sides of the tire. Then, rotate the second double-acting screw, and the two nut blocks drive the two tire clamps through the sliding sleeve to complete the clamping of the tire. The maintenance personnel can remove the tire by taking out the corresponding wrench from the toolbox, and then pull the slide outward to remove the tire from the car. The tire can be easily removed without manual handling.

[0028] In this invention, the protective box is equipped with a dual-axis cylinder. The two L-shaped rotating flaps, with their sides close to each other, are each rotatably connected to a rotating plate via a base. The ends of the two rotating plates, also close to each other, are rotatably connected to the two output shafts of the dual-axis cylinder. When the two output shafts of the dual-axis cylinder retract, they rotate the two L-shaped rotating flaps 90°, at which point the L-shaped rotating flaps unfold, exposing the relevant maintenance equipment and toolboxes inside the vehicle for easy access by maintenance personnel. The combination of the L-shaped rotating flaps and the rain shield also provides sun protection, making it easier for maintenance personnel to work.

[0029] In this invention, the top of the sliding plate has two rotating shafts, and the bottom sides of the sliding plate are provided with two first electromagnets. The top of each of the two first electromagnets is provided with multiple steel wire ropes, and the top ends of the multiple steel wire ropes extend to the top of the sliding plate and are fixedly connected to the outer wall of the rotating shaft. One end of each of the two rotating shafts is fixed with a worm gear, and the worm meshes with the two worm gears. The worm gear drives the two rotating shafts to rotate in opposite directions. The first electromagnets place the lifting structure on the ground. After the first electromagnets are de-energized, they release the magnetic attraction to the lifting plate, which can control the lifting of the lifting structure. This facilitates the automatic removal and storage of the lifting structure in the later stages without manual operation, which not only improves the maintenance efficiency of maintenance personnel, but also avoids injury to maintenance personnel during the handling process.

[0030] In this invention, a locking pin slides through the placement plate, and the locking pin has an inclined surface on the side near the door. The top of the sliding plate has a groove that cooperates with the locking pin. Pulling the locking pin upward releases the engagement between the locking pin and the groove, so that the toolbox remains stationary when the sliding plate is moved out of the compartment, ensuring that maintenance personnel are not exposed to rain or snow when changing tools. The engagement between the locking pin and the groove allows the sliding plate to move the placement plate out of the compartment, which not only makes it easy for maintenance personnel to retrieve the corresponding maintenance tools, but also allows the relevant maintenance instruments on the placement plate to be exposed to the sun, preventing them from getting damp.

[0031] In this invention, a second bidirectional lead screw is rotatably connected within the movable groove, and two nut blocks threadedly connected to the second bidirectional lead screw are slidably connected within the movable groove. Multiple telescopic rods are fixed to both sides of each nut block by bolts, and the output shafts of these telescopic rods are fixedly connected to tire clamps. The tire clamps are stretched outwards, with the two clamps positioned on either side of the tire. Then, the second bidirectional lead screw is rotated to drive the two tire clamps to hold the tire. After removing the tire, the sliding plate is pulled outwards, allowing the tire to be easily removed from the vehicle without manual handling.

[0032] In this invention, the combination of the L-shaped rotating flap and the rain shield enables maintenance personnel to carry out maintenance work normally in rainy and snowy weather. The control structure can easily transport the lifting structure, improving the maintenance efficiency of maintenance personnel and preventing injuries during the transportation process. In addition, the lifting structure can not only lift the car but also cooperate with the tire removal structure to remove the tires, making maintenance work easier. Attached Figure Description

[0045] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0046] Example 1

[0047] Reference Figures 1-9 A vehicle-mounted mobile auto repair station, used in the field of auto repair equipment, includes a cargo box 2 fixed to the top of a car bed by bolts. A placement plate 4 and a sliding plate 5 are slidably connected inside the cargo box 2, with the placement plate 4 located above the sliding plate 5. The bottom of the placement plate 4 is provided with multiple pulleys, which contact the top of the sliding plate 5. Multiple toolboxes 47 are fixed to both sides of the top of the placement plate 4 by bolts. Corresponding auto repair instruments of the car 1 are placed on the top of the placement plate 4. A lifting structure 6 is provided below the sliding plate 5, and the lifting structure 6 slides on the bottom inner wall of the cargo box 2. Two doors 3 are hinged to one side of the cargo box 2, and the doors 3 are used to close the cargo box 2.

[0048] Reference Figures 1-3The repair station also includes shielding structures on both sides of the carriage 2 to protect repair personnel and those being repaired from rain and snow. The shielding structures include L-shaped rotating flaps 7 rotatably connected to both sides of the carriage 2. A protective box 9 is located on the top of the carriage 2, containing a dual-axis cylinder 10. The two output shafts of the dual-axis cylinder 10 extend to the outside of the protective box 9. Bases 12 are welded to the sides of the two L-shaped rotating flaps 7 that are close to each other. Rotating plates 13 are rotatably connected to the sides of the two bases 12. The ends of the two rotating plates 13 that are close to each other are rotatably connected to the two output shafts of the dual-axis cylinder 10. A first magnet ring 11 is bolted to the bottom of the protective box 9, and the first magnet ring 11 is used to increase... The connection between the wire rope 19 and the carriage 2 is such that the bottom of the wire rope 19 is fixed with two guide rods 14 by bolts, and the bottom end of the guide rods 14 slides into the carriage 2, and the guide rods 14 and the carriage 2 slide in a sealed manner; when the dual-shaft cylinder 10 is activated, the two output shafts of the dual-shaft cylinder 10 retract, and through the cooperation of the base 12 and the rotating plate 13, the two L-shaped rotating flaps 7 rotate 90°. At this time, the L-shaped rotating flaps 7 unfold, which can expose the relevant maintenance instruments and toolbox 47 in the carriage 2 for easy use by maintenance personnel. The vehicle to be repaired is located directly below the L-shaped rotating flaps 7, and through the cooperation of the L-shaped rotating flaps 7 and the rain shield 8, sunshade can also be provided, making it easier for maintenance personnel to work.

[0049] Reference Figure 1 Two L-shaped rotating flaps 7 are slidably connected to rain shields 8 on opposite sides, and the rain shields 8 can increase the area of ​​rain and snow protection. Bolts are threaded through the internal threads of the L-shaped rotating flaps 7, and the bolts can brake the rain shields 8. By loosening the bolts, the locking between the L-shaped rotating flaps 7 and the rain shields 8 can be released, and the rain shields 8 can be pulled out to control the area of ​​rain and snow protection of the L-shaped rotating flaps 7 and the rain shields 8, thereby protecting maintenance personnel from rain and snow and making it easier for them to work.

[0050] Reference Figure 2 , Figure 4 , Figure 5 and Figure 6The maintenance station also includes a control structure located on top of the sliding plate 5, used to control the lifting structure 6 to raise and lower, and to complete the storage and retrieval of the lifting structure 6. The control structure includes two rotating shafts 17 rotatably connected to the top of the sliding plate 5 via support plates. Two first electromagnets 21 are provided on both sides of the bottom of the sliding plate 5. Multiple steel wire ropes 19 are provided on the top of each of the two first electromagnets 21, and the top ends of the multiple steel wire ropes 19 extend to the top of the sliding plate 5 and are fixedly connected to the outer wall of the rotating shafts 17. Guide rollers 20 are rotatably connected to both sides of the top of the sliding plate 5 via support plates, and the two guide rollers 20 are used to guide the multiple steel wire ropes 19 on the two first electromagnets 21. Worm gears 18 are fixed to one end of each of the two rotating shafts 17. A drive motor 22 is fixed to the top of the sliding plate 5 by bolts. The output shaft of the drive motor 22 is fixed with a worm gear 23 via a coupling, and the worm gear 23 meshes with two worm wheels 18. Storage slots 25 are provided on both sides of the bottom of the sliding plate 5, and support legs 24 for supporting the sliding plate 5 are rotatably connected within the storage slots 25. The drive motor 22 drives the worm gear 23 to rotate, and the worm gear 23 drives two rotating shafts 17 to rotate in opposite directions via the two worm wheels 18. With the steel wire rope 19 slack, the first electromagnet 21 places the lifting structure 6 on the ground. Then, the power to the first electromagnet 21 is turned off, releasing the magnetic attraction of the first electromagnet 21 to the lifting plate 28, thus controlling the lifting and lowering of the lifting structure 6. This facilitates the automatic removal and storage of the lifting structure 6 later, eliminating the need for manual operation, improving the maintenance efficiency of maintenance personnel, and preventing injuries during handling.

[0051] Reference Figure 4 A locking pin 15 slides through the placement plate 4. The locking pin 15 has an inclined surface on the side near the door 3. The top of the sliding plate 5 has a groove 16 that cooperates with the locking pin 15. In rainy or snowy weather, the locking pin 15 is pulled upward to release the engagement between the locking pin 15 and the groove 16. Thus, when the sliding plate 5 moves the lifting structure 6 out of the carriage 2, the toolbox 47 remains in the carriage 2, ensuring that maintenance personnel are not exposed to rain or snow when changing tools. Similarly, through the engagement of the locking pin 15 and the groove 16, the sliding plate 5 can move the placement plate 4 out of the carriage 2, which not only makes it easy for maintenance personnel to take out the corresponding maintenance tools, but also allows the relevant maintenance tools on the placement plate 4 to be exposed to the sun, preventing them from getting damp.

[0052] Reference Figures 6-8The lifting structure 6 includes two movable bases 26 and two connecting rods 27. The two ends of the connecting rods 27 are welded to the adjacent sides of the two movable bases 26. Each movable base 26 has multiple casters at its bottom. Each movable base 26 has a lifting plate 28 for lifting the car 1. Each movable base 26 has two first bidirectional lead screws 29 rotatably connected inside. The outer walls of each first bidirectional lead screw 29 are threaded with two sliding seats 30. The two sliding seats 30 located on the same first bidirectional lead screw 29 are respectively located on the positive and negative thread sections of the first bidirectional lead screw 29. The tops of the two sliding seats 30... Both are rotatably connected to a connecting rod 31, and the top of the connecting rod 31 is rotatably connected to the bottom of the lifting plate 28. Two tire removal structures 32 are provided on the opposite sides of the two lifting plates 28, and the tire removal structures 32 are used to remove the tires of the car 1. The lifting structure 6 is moved to the bottom of the chassis of the car 1, and the lifting structure 6 is located between the front and rear wheels. The first double-acting screw 29 is driven to rotate by the motor, and multiple first double-acting screws 29 rotate synchronously. The two sliding seats 30 move towards each other. The sliding seats 30 lift the lifting plate 28 upward through the connecting rod 31, so as to lift the car 1 as a whole, making it easier for maintenance personnel to repair the car 1.

[0053] Reference Figure 7 The lifting plate 28 has a sheet metal layer inside, and the first electromagnet 21 is magnetically connected to the lifting plate 28 through the sheet metal layer; and the magnetic attraction of the first electromagnet 21 to the lifting plate 28 is extremely strong, which can completely attract the lifting structure 6 and is used to control the lifting and lowering of the lifting structure 6.

[0054] Reference Figures 7-9The tire removal structure 32 includes two connecting arms 33 welded to one side of the lifting plate 28. One end of each connecting arm 33 is slidably connected to the same sliding plate 34. A movable groove 35 is provided on the side of the sliding plate 34 away from the connecting arms 33. A second bidirectional lead screw 36 is rotatably connected within the movable groove 35, with one end of the second bidirectional lead screw 36 extending to the outside of the sliding plate 34. Two nut blocks 37, threadedly connected to the second bidirectional lead screw 36, are slidably connected within the movable groove 35. The two nut blocks 37 are located on the positive and negative thread sections of the second bidirectional lead screw 36, respectively. A sliding sleeve 38 is bolted to one side of each of the two nut blocks 37, and the sliding sleeve 38 is slidably fitted onto the outer wall of the sliding plate 34. A tire clamp 40 is provided on one side of the sliding sleeve 38, and the tire clamp 40 is used to clamp the tire. The tire clamps 40 are provided with anti-slip grooves 41 on the sides of their close proximity. Multiple telescopic rods 39 are fixed to both sides of the nut block 37 by bolts. The output shafts of the multiple telescopic rods 39 pass through the sliding sleeve 38 and are fixedly connected to the tire clamps 40. When it is necessary to remove the tire of the car 1, the tire clamps 40 are stretched outward, the output shafts of the telescopic rods 39 are extended, and the two tire clamps 40 are located on both sides of the tire. Then, the second double-acting screw 36 is rotated, and the two nut blocks 37 drive the two tire clamps 40 through the sliding sleeve 38 to complete the clamping of the tire. The maintenance personnel take out the corresponding wrench from the toolbox 47 to remove the tire. Then, the sliding plate 34 is pulled outward, and the tire can be removed from the car 1. The tire can be easily removed without manual handling.

[0055] Example 2

[0056] refer to Figure 10 and Figure 11An improvement on embodiment 1: A second magnet ring 42 is fixedly embedded in the top inner wall of the 15 latch, and a second electromagnet 43 is fixedly embedded in the top of the placement plate 4. A repulsive force is generated between the second magnet ring 42 and the second electromagnet 43. The bottoms of the two guide rods 14 are fixed to the same extrusion plate 46 by bolts. A first metal contact piece 44 is fixed to the top of the extrusion plate 46 by bolts. A second metal contact piece 45 is fixed to the top inner wall of the carriage 2 by bolts, and the second metal contact piece 45 cooperates with the first metal contact piece 44. Both the first metal contact piece 44 and the second metal contact piece 45 are electrically connected to the second electromagnet 43. The first metal contact 44 and the second metal contact 45 are respectively connected to the positive and negative poles of the external power supply. The protective box 9 rises under the action of the L-shaped rotating flap 7, and the pressing plate 46 drives the first metal contact 44 and the second metal contact 45 to touch. At this time, the second electromagnet 43 is energized and generates a repulsive force on the second magnet ring 42. The locking pin 15 is disengaged from the locking groove 16. When the sliding plate 5 moves the lifting structure 6 out of the carriage 2 later, it can prevent the placement plate 4 and the tool box 47 from being moved out of the carriage 2 as well, ensuring that maintenance personnel can easily take out the corresponding maintenance tools from the tool box 47 under the cover of the L-shaped rotating flap 7 and the rain shield 8.

[0057] A method for using a vehicle-mounted mobile auto repair station includes the following steps:

[0058] S1. This repair station has two operating modes: rainy / snowy weather and sunny weather. When used in rainy / snowy weather, the dual-shaft cylinder 10 is activated, and the two output shafts of the dual-shaft cylinder 10 retract. Through the cooperation of the base 12 and the rotating plate 13, the two L-shaped rotating flaps 7 rotate 90°. At this time, the L-shaped rotating flaps 7 unfold, which can expose the relevant repair instruments and toolbox 47 in the compartment 2 for easy use by repair personnel. The vehicle to be repaired is located under the L-shaped rotating flaps 7. By loosening the bolts, the locking between the L-shaped rotating flaps 7 and the rain shield 8 can be released, and the rain shield 8 can be pulled out to control the area of ​​rain and snow blocked by the L-shaped rotating flaps 7 and the rain shield 8. Similarly, in summer, the cooperation of the L-shaped rotating flaps 7 and the rain shield 8 can also provide sunshade, making it easier for repair personnel to work.

[0059] S2. Additionally, when the two L-shaped rotating flaps 7 rotate, the protective box 9 rises under the action of the L-shaped rotating flaps 7, and the pressing plate 46 causes the first metal contact 44 to contact the second metal contact 45. At this time, the second electromagnet 43 is energized, and the second electromagnet 43 generates a repulsive force on the second magnet ring 42, causing the locking pin 15 to disengage from the slot 16. When the sliding plate 5 moves the lifting structure 6 out of the carriage 2 later, it can prevent the placement plate 4 and the toolbox 47 from being moved out of the carriage 2 as well, ensuring that maintenance personnel can easily take out the corresponding maintenance tools from the toolbox 47 under the cover of the L-shaped rotating flaps 7 and the rain shield 8.

[0060] S3. When maintenance is carried out in normal weather, the sliding plate 5 is pushed out of the carriage 2 by the cylinder (or the electric slide rail, both of which are existing technologies and are not shown here, so they will not be described in detail). The locking pin 15 is locked into the slot 16 under its own weight. Therefore, the sliding plate 5 drives the placement plate 4 to move out through the locking pin 15. This not only makes it easy for maintenance personnel to take out the corresponding maintenance tools, but also allows the relevant maintenance instruments on the placement plate 4 to be exposed to the sun and prevents them from getting damp.

[0061] S4. When the sliding plate 5 moves the lifting structure 6 out of the car body 2, the drive motor 22 drives the worm 23 to rotate. The worm 23 drives the two rotating shafts 17 to rotate in opposite directions through the two worm wheels 18. The first electromagnet 21 places the lifting structure 6 on the ground under the slack of the wire rope 19. Then, the power to the first electromagnet 21 is turned off, and the first electromagnet 21 releases the magnetic attraction of the lifting plate 28 (the lifting plate 28 has a sheet metal layer, and the magnetic attraction of the first electromagnet 21 to the lifting plate 28 is very strong, which can completely attract the lifting structure 6). The lifting structure 6 is moved to the bottom of the chassis of the car 1 and is located between the front and rear wheels. The motor drives the first double-acting screw 29 to rotate, and multiple first double-acting screws 29 rotate synchronously. The two sliding seats 30 move in opposite directions. The sliding seats 30 lift the lifting plate 28 upward through the connecting rod 31 to lift the entire car 1.

[0062] S5. When it is necessary to remove the tire of car 1, the tire clamp 40 is stretched outward, the output shaft of the telescopic rod 39 is extended, the two tire clamps 40 are located on both sides of the tire, and then the second double-acting screw 36 is rotated. The two nut blocks 37 drive the two tire clamps 40 through the sliding sleeve 38 to complete the clamping of the tire. The maintenance personnel take out the corresponding wrench from the toolbox 47 to remove the tire. Then, the sliding plate 34 is pulled outward, and the tire can be removed from car 1. The tire can be easily removed without manual handling.

[0063] However, as is well known to those skilled in the art, the working principles and wiring methods of the second metal contact 45, the first metal contact 44, the second electromagnet 43, the first electromagnet 21, the drive motor 22, and the dual-axis cylinder 10 are commonplace and belong to conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

10. The method of using a vehicle-mounted mobile auto repair station according to claim 9, characterized in that, Includes the following steps: S1. The repair station is divided into two usage modes: rainy / snowy weather and sunny weather. When used in rainy / snowy weather, the dual-shaft cylinder (10) is started. The two output shafts of the dual-shaft cylinder (10) retract and drive the two L-shaped rotating flaps (7) to rotate 90° through the cooperation of the base (12) and the rotating plate (13). At this time, the L-shaped rotating flaps (7) unfold and can expose the relevant repair instruments and toolbox (47) in the compartment (2) for easy use by repair personnel. The vehicle to be repaired is located under the L-shaped rotating flaps (7). By loosening the bolts, the locking between the L-shaped rotating flaps (7) and the rain shield (8) is released, and the rain shield (8) can be pulled out to control the area of ​​rain and snow covered by the L-shaped rotating flaps (7) and the rain shield (8). Similarly, in summer, the L-shaped rotating flaps (7) and the rain shield (8) can also provide shade. S2. In addition, when the two L-shaped rotating flaps (7) are rotating, the protective box (9) rises under the action of the L-shaped rotating flaps (7), and the pressing plate (46) drives the first metal contact (44) to contact the second metal contact (45). At this time, the second electromagnet (43) is energized, and the second electromagnet (43) generates a repulsive force on the second magnet ring (42). The locking pin (15) is disengaged from the slot (16). When the sliding plate (5) moves the lifting structure (6) out of the carriage (2) later, it can prevent the placement plate (4) and the toolbox (47) from being moved out of the carriage (2) as well, ensuring that maintenance personnel can easily take out the corresponding maintenance tools from the toolbox (47) under the cover of the L-shaped rotating flaps (7) and the rain shield (8). S3. When maintenance is carried out in normal weather, the sliding plate (5) is pushed out of the carriage (2) by the cylinder, and the locking pin (15) is locked into the slot (16) under its own weight. Therefore, the sliding plate (5) drives the placement plate (4) to move out through the locking pin (15), which not only makes it easy for maintenance personnel to take out the corresponding maintenance tools, but also allows the relevant maintenance instruments on the placement plate (4) to be exposed to the sun. S4. When the sliding plate (5) moves the lifting structure (6) out of the carriage (2), the worm gear (23) is driven to rotate by the drive motor (22). The worm gear (23) drives the two rotating shafts (17) to rotate in opposite directions through the two worm wheels (18). The first electromagnet (21) places the lifting structure (6) on the ground under the slack of the wire rope (19). Then the power to the first electromagnet (21) is turned off, and the first electromagnet (21) releases the magnetic attraction to the lifting plate (28) (the lifting plate (28) has a sheet metal layer, and The first electromagnet (21) has a very strong magnetic attraction to the lifting plate (28), which can completely attract the lifting structure (6), move the lifting structure (6) to the bottom of the car (1) chassis, and the lifting structure (6) is located between the front and rear wheels. The first double-acting screw (29) is driven to rotate by the motor, and multiple first double-acting screws (29) rotate synchronously.

When it is necessary to remove the tire of the car (1), stretch the tire clamp (40) outward, extend the output shaft of the telescopic rod (39), and place the two tire clamps (40) on both sides of the tire. Then rotate the second double-acting screw (36), and the two nut blocks (37) drive the two tire clamps (40) through the sliding sleeve (38) to complete the clamping of the tire. The maintenance personnel remove the tire by taking out the corresponding wrench from the toolbox (47), and then pull the sliding plate (34) outward to remove the tire from the car (1).
