Technical Field

[0001] This utility model belongs to the technical field of mobile vehicle maintenance equipment, and in particular relates to a comprehensive repair vehicle. Background Technology

[0002] Currently, during the charging and repair process of new energy vehicles, users need to spend a considerable amount of time transferring their vehicles to repair or charging points, significantly increasing the charging cycle. While vehicle-mounted mini tire changers require lifting the tires onto the vehicle body and manually changing the tire pressure wheel and tire hooks, this process is inconvenient, time-consuming, and labor-intensive. Furthermore, these vehicles do not offer charging assistance or roadside assistance. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a comprehensive maintenance vehicle that is easy to move and has functions such as emergency charging and rescue, tire repair and simple maintenance.

[0004] To address the aforementioned technical problems, this utility model provides a comprehensive maintenance vehicle, comprising a vehicle body and, from front to back, a driver's area, an equipment area, and a tire changer area. The equipment area has a vehicle-mounted dynamic balancing machine and an electrical equipment cabinet on its front left side. The electrical equipment cabinet contains an inverter / charger and a battery, and a charging pile is located outside the cabinet. The inverter / charger is connected to both the battery and the charging pile. A consumables cabinet is located on the left side of the vehicle body behind the left sliding door. A ground-mounted generator is located at the front right side, with an air compressor above it. A tool cabinet is located at the rear right side of the vehicle body, with a tire storage area above it. A vehicle-mounted tire changer is located in the middle of the vehicle body.

[0005] This utility model's integrated maintenance vehicle is a multi-functional special-purpose vehicle, equipped with emergency charging and rescue, tire repair, and simple maintenance functions. The equipment in the rear compartment is rationally arranged, and the layout of the various doors allows for quick and convenient operation. The rear compartment can carry a spare tire, as well as necessary tools and spare parts for the service scenario.

[0006] This utility model installs a vehicle-mounted tire changer on a vehicle to complete tire removal, installation, and inflation. The tire changer consists of a tire changer body, tire clamps, working arm assembly, tire removal assistant, and control mechanism. There is no need to change tire removal accessories. The entire operation is automated, greatly reducing labor intensity. Furthermore, the tire changer can get on and off the vehicle and can move with the vehicle, which can greatly reduce the waste of manpower and material resources.

[0007] The optimized technical solution of this utility model is as follows:

[0008] Furthermore, the vehicle-mounted tire changer consists of a tire changer and a tire changer tilting frame, with the tire changer mounted on the tire changer tilting frame.

[0009] Furthermore, the tire changer's tilting frame consists of a fixed frame, a movable frame, and a tilting connecting frame. The fixed frame is installed at the bottom of the vehicle compartment, the movable frame is mounted on the fixed frame and can move back and forth along the fixed frame, and the tilting connecting frame is mounted on the movable frame. The tire changer consists of a tire changer body, a tire clamp, a working arm assembly, a tire scraper, and a control mechanism. The tire changer body is mounted on the tilting connecting frame, the tire scraper and the working arm assembly are mounted on the tire changer body, and the tire clamp and the control mechanism are mounted on the working arm assembly.

[0010] In this way, the vehicle-mounted tire changer is installed on the vehicle to complete the tire removal, installation, and inflation, and it can get on and off the vehicle itself and reliably accompany the vehicle.

[0043] Table 1 Parameters of Vehicle-Mounted Tire Changer

[0044]

[0045] As shown in Table 1, the STD-212D vehicle-mounted car tire changer uses a 110-220V / 50-60Hz / 1PH power supply for the chuck's rotational force and an 8-10 bar air source for the cylinder's actuation power. It is installed on logistics vehicles or box trucks with a chassis strength greater than 500 kg / m² to perform tire changing, inflation, and dispensing on car tires. It can also be mounted and dismounted from vehicles and reliably move with them. The STD-212D vehicle-mounted car tire changer has two modes: an in-vehicle retractable transport mode and an under-vehicle extended working mode.

[0046] The monitoring system includes a first monitoring camera, a second monitoring camera, a third monitoring camera, and a vehicle-mounted terminal 19. The first monitoring camera is located on the roof of the vehicle in the driver's cabin; the second monitoring camera is located at the left sliding door 23 in equipment area B; the third monitoring camera is located on both sides of the rear tailgate; and the vehicle-mounted terminal 19 is located below the passenger seat and is connected to the first, second, and third monitoring cameras. The vehicle-mounted terminal 19 has vehicle networking capabilities, enabling it to upload vehicle information in real time. The monitoring cameras can record images of the vehicle interior and various workstations, and support local storage and remote viewing.

[0047] The vehicle power supply system includes three power supply modes: ground-mounted generator 7, inverter power supply, and external AC mains power supply. The ground-mounted generator 7 has automatic and manual modes, and provides stable AC220V power to the onboard equipment. The inverter power supply system is powered by the battery 5 through the inverter-charger 4. The external AC mains power supply system connects one end of the cable to the vehicle's external AC mains interface and the other end to a household AC mains socket.

[0048] The rear of the vehicle features two doors: a left sliding door 23 on the left and an upward-opening door 20 and a downward-opening door 21 on the right. In use, opening the left sliding door 23 allows the onboard dynamic balancing machine 1 to be pulled out for tire dynamic balancing calibration. After calibrating the tires, the onboard dynamic balancing machine 1 reduces the stability of the vehicle's chassis suspension, enhances driving comfort, maintains straight-line stability, reduces tire wear, increases tire lifespan, and improves driving safety. The onboard dynamic balancing machine 1 maintains a relatively stable state even when the tires are rotating at high speeds, thus ensuring normal vehicle operation.

[0049] The electrical equipment cabinet 2 is equipped with a charging pile 3, which can provide emergency charging and rescue for new energy vehicles;

[0050] On the left side of the vehicle body, behind the left sliding door 23, there is a consumables cabinet 6, which stores mushroom nails, crayons, windshield washer fluid, antifreeze, multi-functional patches, oil blotting paper, etc.

[0051] A ground-mounted generator 7 is installed on the right side of the vehicle, providing a stable AC 220V power output to the onboard equipment. An air compressor 8 is located above the generator 7; the onboard tire changer 10 requires the use of the air compressor 8. The air compressor 8 provides high-pressure gas to help separate the tire from the rim, facilitating tire replacement or repair. The air compressor 8 is maintained by opening the upper door 20 on the right side, and the ground-mounted generator is maintained by opening the lower door 21 on the right side.

[0052] Open the rear double doors to retrieve tools and use the on-site tire changer. A tool cabinet 9 is located at the rear of the vehicle body, which can store wrenches, battery testers, oil cans, emergency power supplies, a vehicle vacuum cleaner, a jack, a tire pressure gauge, etc. Above the tool cabinet 9 is the tire storage area E, which can also carry a spare tire. A vehicle-mounted tire changer 10 is located in the middle of the vehicle body. The vehicle-mounted tire changer 10 is installed on the vehicle to perform tire removal, installation, and inflation. It can be loaded and unloaded from the vehicle and can travel alongside it. The tire changer is existing equipment; its structure and operation will not be described in detail here.
