Problems solved by technology

[0003] When the car is not in maintenance time, when the car tire leaks due to jogging gas or being punctured or other conditions, it will bring safety hazards to the driving of the car. When this happens and the spare tire cannot be replaced in time, it cannot be found in time When the vehicle is being repaired, you can only wait for the help of rescuers, resulting in a passive situation and bringing a lot of inconvenience to the owner

Embodiment 1

[0025] A vehicle-mounted tire inflation device is provided, which can be applied to vehicles such as bicycles, motorcycles, automobiles, and various engineering vehicles. figure 1 As shown, it includes an air pump 1 and a transfer air chamber 2. The air pump 1 is generally placed in the front compartment of the automobile, the transfer air chamber 2 is sleeved on the outer periphery of the axle 3, the transfer air chamber 2 is fixed on other static structures of the automobile, and the axle 3 In the process of driving the tire A to rotate, the transfer air chamber 2 does not follow the rotation of the axle 3. Specifically, a bearing 4 is provided between the inner wall of the transfer air chamber 2 and the outer periphery of the axle 3, so that the axle 3 can rotate flexibly in the transfer air chamber 2 Without any influence, there are interconnected gas inlet 31 and gas outlet 32 ​​on the axle 3, and the gas inlet 31 is covered by the transfer air chamber 2 to ensure that the...

Embodiment 2

[0033] The difference between this embodiment and Embodiment 1 is that: the transit air chamber 2 is not arranged on the axle, but a round rod 9 is vertically installed on the hub, as figure 2 As shown, the round rod 9 is located inside the tire A, and the transfer air cavity 2 is set on the outer periphery of the round rod 9. The design of the gas inlet on the round rod is the same as that in Embodiment 1, and the gas outlet is arranged on the outer periphery of the round rod. The second air intake pipe 6 is exposed on the outside of the tire; the configuration of other components in the inflation device refers to the relevant records of embodiment 1.

[0034] An additional round rod is installed on the wheel hub. Compared with Embodiment 1, the possible burden or influence of the inflation device on the axle can be fully avoided, and at the same time, there is no need to drill the axle, and the original structure of the vehicle does not need to be changed.

Embodiment 3

[0036] The difference between this embodiment and embodiment 2 is: the transfer air cavity and the round rod are located outside the tire, which can also realize the instant inflation of the tire. However, compared with embodiment 1 and embodiment 2, this solution will affect the appearance of the car. It will take up space on the outside of the tire and is not the best choice.

Abstract

The invention relates to the technical field of tire inflation and discloses a vehicle-mounted tire inflation device. The device comprises an inflator pump and a transfer gas cavity, the transfer gascavity sleeves a periphery of a round rod which is perpendicular to the wheel and can synchronously rotate along with the wheel; the transfer gas cavity is connected to the vehicle and does not rotatealong with the round rod; and the round rod is provided with a gas inlet and a gas outlet, the gas inlet is covered by the transfer gas cavity, a first gas inlet pipe is arranged between the inflatorpump and the transfer gas cavity, a second gas inlet pipe is arranged between a round rod gas outlet and a tire valve, and a reversing valve is arranged on the first gas inlet pipe and / or the secondgas inlet pipe. The device does not need to be disassembled after being installed on a vehicle, an influence is not generated on operation of the vehicle, and the device can respond and supplement airin time when the tire needs to be inflated no matter in emergency or in case of daily gas loss of the tire; and the device is high in applicability and can be installed on any vehicle with two wheels, three wheels, four wheels and more than four wheels, and when the device is installed on the inner side of the tire, the appearance of the vehicle is not influenced at all.

Description

technical field [0001] The invention relates to the technical field of tire inflation, in particular to a vehicle-mounted tire inflation device. Background technique [0002] With the popularization of automobiles, most families are equipped with automobiles. However, automobiles are consumables, and all parts need frequent maintenance. Among them, tire jogging air often occurs. During regular maintenance of automobiles, tire pressure is a must-check item. , so the amount of inflation in the tire has a crucial impact on the driving of the car. [0003] When the car is not in maintenance time, when the car tire leaks due to jogging gas or being punctured or other conditions, it will bring safety hazards to the driving of the car. When this happens and the spare tire cannot be replaced in time, it cannot be found in time. When the vehicle is being repaired, it can only wait for the help of rescuers, resulting in a passive situation and bringing a lot of inconvenience to the c...
