[0002] With the advancement of the industrial economy, automobiles have become increasingly common, and roads and highways have gained increasing attention and development. The speed and convenience of highways have changed people's perception of time and space, shortened geographical distances, and improved their lifestyles. However, the resulting wave of serious highway traffic accidents has been shocking, attracting intense attention and concern from countries around the world, leading to discussions and implementation of preventive measures. During high-speed driving, tire failure is the most devastating and difficult-to-prevent potential accident hazard and a major cause of sudden traffic accidents. Tackling tire failure and preventing blowouts have become top global concerns.

[0003] The current method for monitoring tire pressure is to place it externally on the tire valve stem, which is prone to damage and loss, making this solution less than ideal. Alternatively, pneumatic pressure sensors placed inside the wheel hub, as is customary, cannot measure the pressure inside the tire through the inner tire wall. Therefore, a new design for an automotive wheel hub cavity with a pneumatic pressure balancing mechanism has been proposed. Summary of the Invention

[0006] The air pressure balancer housing, the first slide plate and the second slide plate are all in a cylindrical shape, and sealing rings are fixedly connected to the outer sides of the first slide plate and the second slide plate.

[0007] The turntable is provided with a through hole, and a latch is slidably connected in the through hole.

[0008] A pin hole matched with the latch is provided on the left side of the air pressure balancer housing.

[0009] Bolts are threadedly connected to the wheel hubs on both sides of the air pressure balancer housing, and the air pressure balancer housing is fixedly connected to the wheel hubs by the bolts.

[0010] The pressure value display is provided with an alarm.

[0011] The utility model has the following beneficial effects:

[0012] In the utility model, an air bag is provided in the wheel hub and is connected to the air pressure balancer. During driving, when the air pressure in the air pressure balancer housing is less than or greater than a set value, the second slide plate is moved to the right or left side under the action of the spring, so as to balance the pressure. At the same time, an alarm on the pressure value display sounds an alarm. When the pressure needs to be adjusted, the turntable is rotated to drive the first slide plate and the second slide plate to move left and right, which is convenient for operation.

[0020] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0021] Reference Figure 1-4 The embodiment of the present invention provides an inner cavity of an automobile wheel hub with a pneumatic pressure balancing mechanism, which includes a wheel hub 1 and a tire 2. The wheel hub 1 is provided with an opening 4, in which a pneumatic pressure balancer housing 5 is installed. Bolts 13 are threadedly connected to the wheel hub 1 on both sides of the pneumatic pressure balancer housing 5, and the pneumatic pressure balancer housing 5 is fixedly connected to the wheel hub 1 by the bolts 13.

[0022] An airbag 3 is provided on the wheel hub 1 on the right side of the air pressure balancer housing 5. The airbag 3 can be expanded and compressed. A pipe 31 is provided on the airbag 3. The pipe 31 passes through the wheel hub 1 and is fixedly connected to the air pressure balancer housing 5. The air pressure balancer housing 5 is connected to the airbag 3 through the pipe 31. The air pressure balancer housing 5 adopts the principle of force transmission and PV=C (P gas pressure, V volume, C constant). A first slide 9 and a second slide 10 are slidably connected in the air pressure balancer housing 5. The air pressure balancer housing 5, the first slide 9 and the second slide 10 are all in a cylindrical shape. A sealing ring 11 is fixedly connected to the outside of the first slide 9 and the second slide 10. A spring 12 is fixedly connected between the first slide 9 and the second slide 10. The first slide 9 is rotatably connected to the side away from the spring 12 with a screw 8. The screw 8 is threadedly connected to the air pressure balancer housing 5, and one end located on the outside of the air pressure balancer housing 5 is fixedly connected to a turntable 7. The turntable 7 is located in the opening 4. A through hole 71 is provided on the turntable 7. A latch 14 is slidably connected in the through hole 71. A pin hole that matches the latch 14 is provided on the left side of the air pressure balancer housing 5. When the pressure needs to be adjusted, the turntable 7 is rotated to drive the first slide 9 and the second slide 10 to move left and right, which is convenient for operation.

[0023] A pressure value display 6 is fixedly connected to the outside of the air pressure balancer housing 5, and an alarm is provided on the pressure value display 6. The rear side of the pressure value display 6 is connected to an air pressure detection head through a signal line. The air pressure detection head is located in the air pressure balancer housing 5 on the right side of the second slide 10.

[0024] Working principle: During installation, first install the airbag 3 on the wheel hub 1, pass the pipe 31 through the wheel hub 1 and fix it to the air pressure balancer housing 5, then install the tire 2 on the outside, and then install the air pressure balancer in the opening 4 on the wheel hub 1 through the bolts 13. After the installation is completed, inflate the tire 2 through the valve nozzle. At this time, the air pressure generated in the tire 2 acts on the airbag 3, causing the airbag 3 to be squeezed inward, and the pressure generated by it is transmitted into the air pressure balancer housing 5 through the pipe 31. At this time, the air pressure detection head detects the pressure, and the pressure value display 6 displays the value. When the air pressure in the air pressure balancer housing 5 is less than or greater than the set value, the second slide plate 10 is moved to the right or left under the action of the spring 12 to facilitate pressure balancing. At the same time, the alarm on the pressure value display 6 sounds an alarm;

[0025] When in use, the tire 2 is inflated through the valve nozzle, and the tire stops when the pressure value display 6 reaches the set value. During driving, when the air pressure in the air pressure balancer housing 5 is less than the set value, the second slide plate 10 is moved to the right under the action of the spring 12, so as to balance the pressure, and the alarm on the pressure value display 6 sounds an alarm; when the air pressure in the air pressure balancer housing 5 is greater than the set value, the air pressure squeezes the second slide plate 10, and under the action of the spring 12, the second slide plate 10 is moved to the left, so as to balance the pressure, and the alarm sounds an alarm.

[0026] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
