Generally, sedans emphasize comfort and are passenger-centric. Furthermore, economic considerations prioritize engines with moderate horsepower, small displacement, and low fuel consumption. In mainland China, sedans specifically refer to small cars, as distinct from trucks, pickup trucks, SUVs, buses, and minibuses. Commonly referred to as "sedans," these vehicles are often referred to as "small cars." With the development of society, mobility aids are becoming increasingly common when a sedan breaks down and requires assistance.

[0003] Existing devices, such as CN201721810467.8, describe a vehicle tire air pump comprising a vacuum tank, a motor, a vacuum tank end cap, a tire pressure gauge, an alarm, an automatic shut-off valve, an air pump, a light, a lampshade, and a handle. The motor is placed within the vacuum tank and connected to the tire pressure gauge and the air pump via the vacuum tank end cap. The vacuum tank end cap is placed at the top of the vacuum tank. The tire pressure gauge and the alarm are mounted on the vacuum tank end cap. The automatic shut-off valve is connected to the tire pressure gauge. The light, the lampshade, and the handle are mounted on the outer surface of the vacuum tank, and the light is fixed to the lampshade. This utility model incorporates a lighting device for convenient illumination in dimly lit conditions. It also incorporates an alarm and an automatic shut-off valve that sound an alarm and automatically shut off air intake immediately upon detecting that tire pressure reaches its tolerance, protecting the vehicle tires and facilitating travel.

[0004] During the driving process of a car, the car tire may leak due to special circumstances, causing the car to break down. Currently, most users usually use an air pump to inflate the tire in this situation to help the vehicle continue to drive. However, when workers use the air pump to inflate the tire, the air pump itself vibrates, which causes the air pump to shift and wear severely. Utility Model Content

[0013] 1. In the utility model, by providing a protective device, when a worker uses the air pump, the bottom end of the air pump is protected. When the equipment is used, the equipment drives the piston to reciprocate in the cylinder through power. During the suction stroke, the piston moves outward, forming a negative pressure in the cylinder, and the outside air is sucked into the cylinder through the intake valve; during the compression stroke, the piston moves inward, compressing the inhaled air, reducing its volume and increasing its pressure.

At the same time, the friction between the rubber ring and the ground is strong, which can limit the displacement of the air pump during use. By setting a protective device, the bottom end of the air pump can be effectively protected. When the worker uses the air pump, the protective device is installed to avoid friction and collision between the bottom end of the air pump and the road surface, thereby improving the protection of the protective device to the air pump, reducing the damage of the air pump, extending the service life of the air pump, and reducing the displacement of the air pump.

[0025] Specifically, the inner surface of the slider 33 is threadedly connected to the positioning rod 31 , and the positioning rod 31 is threadedly connected to the inner surface of the guide plate 34 .

[0026] In this embodiment, the positioning rod 31 can cooperate with the slider 33 to achieve the purpose of limiting the sliding of the slider 33.

[0027] In this embodiment: a protective device 4 is provided on the surface of the air pump 1, and the protective device 4 includes a support frame 44, which is fixedly connected to the surface of the air pump 1, and the support frame 44 is located above the rubber ring 37. The support frame 44 can cooperate with the air pump 1 to achieve the purpose of supporting the support frame 44.

[0028] Specifically, the surface of the support frame 44 is rotatably connected to a rotating plate 42 , which is located above the air pump 1 . A torsion spring 43 is fixedly connected to the surface between the rotating plate 42 and the support frame 44 , which is located above the air pump 1 .

[0029] In this embodiment, the rotating plate 42 can cooperate with the support frame 44 to achieve the purpose of supporting and adjusting the support frame 44.

[0030] Specifically, a protective cover 41 is fixedly connected to the surface of one end of the rotating plate 42, and the protective cover 41 is sleeved on the control panel on the surface of the air pump 1. A guide bar 45 is fixedly connected to the surface of the air pump 1, and the guide bar 45 is located on one side of the protective cover 41.

[0032] In this embodiment, the stop block 46 can cooperate with the guide bar 45 to achieve the purpose of guiding the stop block 46 to slide.

[0033] Working principle: By setting the protection device 3, when the worker uses the air pump 1, the bottom end of the air pump 1 is protected and the equipment is used. When the equipment drives the piston to reciprocate in the cylinder through power, during the suction stroke, the piston moves outward to form a negative pressure in the cylinder, and the outside air is sucked into the cylinder through the intake valve; during the compression stroke, the piston moves inward to compress the inhaled air, thereby reducing its volume and increasing its pressure. The compressed high-pressure air is discharged through the outlet valve and then enters the tire through the connecting pipe, thereby achieving the purpose of inflating the tire. The worker puts the rubber ring 37 on the bottom end of the air pump 1. When the placement plate 36 contacts the main plate 32, the slider 33 is pushed. The slider 33 is guided by the guide plate 34. The slider 33 slides and pushes the supporting plate 35. The supporting plate 35 slides and supports the placement plate 36. The positioning rod 31 is rotated and the positioning rod 31 is inserted into the guide plate 34. When the worker uses the air pump 1, the vibration generated by the air pump 1 will rub against the ground. The rubber ring 37 buffers the vibration. At the same time, the friction between the rubber ring 37 and the ground is strong, which can limit the displacement of the air pump 1 during use. By setting the protective device 3, the air pump 1 is effectively protected. At the bottom of the air pump 1, when the worker uses the air pump 1, the protective device 3 is installed to avoid the friction and collision between the bottom of the air pump 1 and the road surface, thereby improving the protection of the protective device 3 to the air pump 1, reducing the damage of the air pump 1, increasing the service life of the air pump 1, and reducing the displacement of the air pump 1. In addition, by setting the protective device 4, when the worker uses the air pump 1, the inconvenience of reading the display screen of the control panel is reduced. When using the equipment, the equipment drives the piston to reciprocate in the cylinder through power. During the suction stroke, the piston moves outward to form a negative pressure in the cylinder, and the outside air is sucked into the cylinder through the intake valve; during the compression stroke, the piston moves inward to compress the inhaled air, thereby reducing its volume and increasing its pressure. The compressed high-pressure air is discharged through the air outlet valve and then enters the tire through the connecting pipe, thereby achieving the purpose of inflating the tire. Rotate the protective cover 41, and the protective cover 41 drives the rotating plate 42. The support frame 44 guides and supports the rotating plate 42 to rotate. When the protective cover 41 is sleeved on the control panel on the surface of the air pump 1, one end of the protective cover 41 will squeeze the block 46, and the block 46 is guided by the guide strip 45. When the protective cover 41 contacts the air pump 1, the return spring 47 pushes the block 46, and the block 46 presses against the protective cover 41. By setting the protective device 4, the inconvenience of reading the display screen of the control panel is effectively reduced. When the worker uses the air pump 1, the protective device 4 is adjusted to avoid friction between the air pump 1 and the vehicle or other objects during carrying, thereby improving the protection of the protective device 4 to the air pump 1, reducing the inconvenience of use for the user, and facilitating the worker to adjust the air pump 1.
