The base 21 is connected with the driving end of the second hydraulic oil cylinder 42 of the mobile unfolding device, and the third hydraulic oil cylinder 44 is connected between the two bases 21. The lifting drive device comprises a first lift arm 22, a second lift arm 23 and a hydraulic drive member 25, the first lift arm 22 and the second lift arm 23 are hingedly connected to each other to form an X-shaped cross structure. One ends of the first lift arm 22 and the second lift arm 23 are connected to the base 21, the other ends of the first lift arm 22 and the second lift arm 23 are connected to the lifting plate 24, one end of the hydraulic drive member 25 is fixed on the base, and the other end of the hydraulic drive member 25 is drivingly connected to the first lift arm 22 (or the other end of the hydraulic drive member 25 is drivingly connected to the second lift arm 23, in this embodiment the other end of the hydraulic drive member 25 is drivingly connected to the first lift arm 22 as an example). The base 21 is lowered onto the ground for providing support, the vehicle to be maintained is moved on the lifting plate 24 and fixed, and the lifting plate 24 is driven by the lifting drive device to be raised to form an overhead space for maintenance operations between the chassis of the vehicle to be maintained and the ground. After the lifting mechanism 20 is unfolded on the ground by using the first hydraulic oil cylinder 41, the second hydraulic oil cylinder 42, and the third hydraulic oil cylinder 44, the base 21 is stably placed on the ground and the vehicle to be moved is moved on the lifting plate 24, and then the hydraulic drive member 25 is activated to drive the first lift arm 22 to move, thereby causing relative movement between the first lift arm 22 and the second lift arm 23, which raises the lifting plate 24, thereby raising the vehicle to be maintained from the ground to form the overhead space.

In the process of taking the lifting mechanism 20 out of the compartment 10 by using the first hydraulic oil cylinder 41 and the second hydraulic oil cylinder 42, in order to ensure the working strength of the first hydraulic oil cylinder 41 and the second hydraulic oil cylinder 42, a first guide sleeve 411 and a first guide shaft 412 that cooperate with each other are provided on the first hydraulic oil cylinder 41, the first guide sleeve 411 is fixedly connected with the cylinder of the first hydraulic oil cylinder 41, the first guide shaft 412 is connected with the drive shaft of the first hydraulic cylinder 41, and the first guide shaft 412 is synchronously moved with the drive shaft of the first hydraulic oil cylinder 41. In addition, a second guide sleeve 421 and a second guide shaft 422 that cooperate with each other are provided on the second hydraulic oil cylinder 42, the second guide sleeve 421 is fixedly connected with the cylinder of the second hydraulic oil cylinder 42, the second guide shaft 422 is connected with the drive shaft of the second hydraulic cylinder 42, and the second guide shaft 422 is synchronously moved with the drive shaft of the second hydraulic oil cylinder 42.

The mobile vehicle maintenance station further includes a control device (not shown in figures). The control device is disposed in the compartment 10, and the mobile unfolding device and the lifting drive device are both electrically connected with the control device. The mobile vehicle maintenance station further includes a hydraulic oil cylinder, and the control device controls the mobile unfolding device and the lifting drive device to uniformly supply the hydraulic oil from the hydraulic oil cylinder to generate hydraulic power, that is, when the control device controls the first hydraulic oil cylinder 41, the second hydraulic oil cylinder 42, and the third hydraulic oil cylinder 44 to start working, the first hydraulic oil cylinder 41, the second hydraulic oil cylinder 42, and the third hydraulic oil cylinder 44 are uniformly supplied with oil from the hydraulic cylinder to provide hydraulic power, and the hydraulic driving member 25 for driving the first lift arm 22 and the second lift arm 23 is also supplied with oil by the hydraulic oil cylinder to provide hydraulic power.

Referring to FIGS. 6 to 8, the mobile vehicle maintenance station in the first embodiment further includes a protection device 30 disposed between the base 21 and the lifting drive device, and the protection device 30 is electrically connected with the control device. In this embodiment, the protection device 30 includes a fixed protection portion 31, a snap-fit protection portion 32 and a jack-up portion 33, and the jack-up portion 33 is activated or closed in synchronization with the hydraulic drive member 25. The fixed protection portion 31 is fixedly disposed on the base 21 (the fixed protection portion 31 may be welded on the base 21), the snap-fit protection portion 32 is movably connected to the first lift arm 22 of the lifting drive device, and the jack-up portion 33 is disposed on the snap-fit protection portion 32, wherein the jack-up portion 33 is a driving cylinder, and the telescopic driving end of the driving cylinder extends beyond the snap-fit protection portion 32 and abuts against the base 21. The snap-fit protection portion 32 has two opposite connecting plates, the first ends of the two connecting plates are hingedly connected to the first lift arm 22 via a hinge shaft 321, the second ends of the two connecting plates are fixedly connected to each other via a snap-fit lever 322, and the fixed protection portion 31 is provided with a plurality of spaced snap-fit openings. After the lifting drive device raises the lifting plate 24, the protection device 30 automatically performs a protection function to prevent the lifting drive device from lowering the lifting plate 24 due to pressure relief. In this embodiment, the snap-fit slots in the fixed protection portion 31 extend in an oblique direction that coincides with the moving direction of the jack-up portion 33 when the vehicle is raised, so that the snap-fit lever 322 of the snap-fit protection portion 32 can reach into the snap-fit slot 322 of the fixed protection portion 31, that is, the snap-fit lever 322 automatically drops into the corresponding snap-fit opening to form a mutual engagement to thereby limit the lifted first lift arm 22 and second lift arm 23, thus the protection device realizes a protection function for the first lift arm 22 and the second lift arm 23, and at this time, the telescopic driving end of the jack-up portion 33 is in an initial retracted state. During the process in which the control device controls the lifting drive device to release pressure and lowers the lifting plate 24, the control device controls the protection function of the protection device 30 to be disabled. The control device is electrically connected to the jack-up portion 33, and the control device controls the telescopic driving end of the jack-up portion 33 to extend. Thus the telescopic driving end ejects the snap-fit lever 322 from the snap-fit opening, and at this time the control device controls the hydraulic drive member 25 to drive the first lift arm 22 and the second lift arm 23 to descend to lower the lifting plate 24, in this way the vehicle to be maintained can be removed from the lifting mechanism 20 and returned to the ground after the maintenance is completed. In this embodiment, the mobile vehicle maintenance station includes an air pump 53 which is installed in the compartment 10. The air pump 53 is in communication with the jack-up portion 33 (the driving cylinder) through an air passage (not shown). In addition, the air pump 53 is electrically connected to the control device, the control device simultaneously controls the operation of the air pump 53 and the jack-up portion 33, and the air pump 53 supplies air to the jack-up portion 33 to provide pneumatic power. The lifting height of the vehicle can be adjusted according to different needs and corresponding to different snap-fit openings, so that the mobile vehicle maintenance station can adapt to different working technicians for follow-up services.

After raising the vehicle to be maintained by using the lifting mechanism 20 of the mobile vehicle maintenance station, the working technician performs various maintenance operations on the vehicle to be maintained, wherein the mobile vehicle maintenance station further includes a tire maintenance equipment. The tire maintenance equipment is installed in the compartment, and the tires of the vehicle to be maintained are maintained by using the tire maintenance equipment. Specifically, the tire maintenance equipment includes a tire demounting device and a tire dynamic balance detecting device which are respectively installed in the compartment, and the tire demounting device is used to perform a tire demounting operation of a wheel removed from the vehicle to be maintained so as to perform tire repair or tire replacement, and the tire dynamic balance detecting device is used to perform dynamic balance detection and maintenance of the wheel after completion of the tire repair or the tire replacement

Further, since the vehicle widths of different vehicles are different, in order to fit different vehicle widths of various vehicles, after the working technician stably places the two bases 21 on the ground, as shown in FIG. 6, the working technician increases the distance between the respective two lifting plates 24 by operating the driving end of the third hydraulic oil cylinder 44 in the first embodiment to continue to extend according to the vehicle width of the vehicle to be maintained to fit different vehicle widths (when the two bases 21 are just lying on the ground, the lifting plate 24 is adapted to the minimum vehicle width). In this embodiment, the base 21 connected with the second hydraulic oil cylinder 42 is provided with a guide sleeve, and the other base 21 is connected with a guide rod which is inserted in the guide sleeve. After the two bases 21 are unfolded by the third hydraulic oil cylinder 44 from the folded state to be placed on the ground, when the third hydraulic oil cylinder 44 continues to drive and extend, the guide rod extends out the guide sleeve, thereby better adjusting the distance between the two bases 21 according to the vehicle width of the vehicle. Correspondingly, during the third hydraulic oil cylinder 44 is retracted, after the guide rod is driven to retract the guide sleeve, the third hydraulic oil cylinder 44 continues to drive and contract, at which time the base 21 away from the second hydraulic oil cylinder 42 can be folded and stored.

When the working technician completes the maintenance of the vehicle, the lifting plate 24 of the vehicle lifting mechanism 20 needs to be lowered to be able to drive the vehicle down to the ground, since the jack-up portion 33 is activated or closed synchronously with the hydraulic driving member 25, when starting the hydraulic drive member 25 to release pressure to lower the vehicle, the telescopic driving end of the jack-up portion 33 is extended to disengage the snap-fit lever 322 of the snap-fit protection portion 32 from the snap-fit opening of the fixed protection portion 31, and then the hydraulic drive member 25 is controlled by the control device to perform pressure relief and the lowering. When the working technician controls the hydraulic drive member 25 through the control device, the controller also controls the jack-up portion 33 to be activated to lift the snap-fit protection portion 32 away from the snap-fit opening of the fixed protection portion 31, thereby enabling the vehicle to be lowered to the ground.

After the vehicle is driven down the lift plate 24 to complete the maintenance work, the working technician needs to re-accommodate the vehicle lifting mechanism 20 back into the compartment and depart again to the next service location. In this embodiment, as shown in FIG. 1, the mobile vehicle maintenance station further includes a horizontal storage protection sensor 43 for detecting the horizontal relative position of the second hydraulic oil cylinder 42 on the compartment 10, and the horizontal storage protection sensor 43 is installed on the compartment 10, and the horizontal storage protection sensor 43 is electrically connected to the control device. When the second hydraulic oil cylinder 42 is horizontally moved and stored to a position spaced apart from the horizontal storage protection sensor 43 by a predetermined distance, the control device controls the first hydraulic oil cylinder 41 to close to stop continuing storing the lifting mechanism 20. In the process of sequentially taking back the lifting mechanism 20 and then moving the lifting mechanism 20 into the compartment 10, since other important machine parts are also provided in the compartment 10, in order to prevent the vehicle lifting mechanism 20 from colliding with other important machine parts, the relative position of the second hydraulic oil cylinder 42 in the compartment 10 is detected by the horizontal storage protection sensor 43, when the relative distance between the second hydraulic oil cylinder 42 and the horizontal storage sensor 43 is the predetermined distance, the control device controls to stop providing the storage power, and at this time the storage is completed.

In the present embodiment, the control device in the compartment 10, various sensors, the tire demounting machine 51, the tire dynamic balancing machine 52, the air pump 53, the lighting device in the compartment 10, and the like all utilize the power supplied by the power generating device 54. Moreover, the power generating device 54 can generate power by utilizing the residual heat of the exhaust gas during the running of the vehicle, then store the power, and provide the power when used, thereby achieving energy saving and environmental protection requirements.

In the second embodiment, the base 21 is a unitary base, which can maintain the stabilization and balance of the entire lifting mechanism 20. Further, the base 21 can be designed as a -shaped fork structure, and the externally expanded -shaped fork structure is subjected to the force of the whole lifting mechanism 20. In addition, in the second embodiment, in order to accommodate vehicles of different vehicle widths, the third hydraulic oil cylinder 44 is used to control the lifting plate 24 to be deployed in two pieces, thereby controlling the separation width of the two lifting plates 24 to adapt to different vehicle widths, at this time, one end of the third hydraulic oil cylinder 44 is fixedly connected to the lifting plate 24 adjacent to the second hydraulic oil cylinder 42, and the driving end of the third hydraulic oil cylinder 44 is connected to the other lifting plate 24 to achieve a separation distance between the lifting plates 24. Preferably, the lifting plates 24 of the second embodiment are attached to the bottom of the chassis of the vehicle to be maintained for lifting. At this time, the lifting plates 24 can be simplified to support four fulcrums of the chassis of the vehicle to be maintained. The fulcrums are connected by connecting rods, and the third hydraulic oil cylinder 44 is connected between the two connecting rods which can be separated from each other, thereby controlling the separation between the respective fulcrums to accommodate different vehicle widths.
