Description

Automatic tyre inflating device for bicycle

Technical Field

The present invention is a mechanical device which can automatically inflate the tyre when the tyre pressure is insufficient during the running of the bicycle by using the power of the vehicle. After the tire is fully inflated, the inflation is automatically stopped. It can also be used for automobile tires.

Background

The current way of inflating vehicle tires is mainly to inflate the tires when the vehicle is stopped. Manual operation is required when the tire is inflated, which is very inconvenient. An inflator attached to a bicycle is lacking, which can automatically inflate the wheels during the running of the bicycle.

Disclosure of Invention

The invention provides a novel inflating device aiming at the problem of inconvenient tire inflation, which is arranged on a wheel and can automatically inflate a tire when the air pressure of the tire is insufficient during the running of a vehicle. After the tire is fully inflated, the inflation is automatically stopped.

The technical scheme for solving the technical problem of the invention is as follows: the wheel is modified, an inflator pump device is connected between an air inlet valve and a rotating shaft of the wheel, the inflator pump rotates along with the wheel, a rotating shaft at the handle of an inflating piston deviates from the rotating shaft of the wheel and is an eccentric shaft, and the piston reciprocates to inflate when the wheel rotates. The eccentric rotating shaft is connected with the ferrule, and the ferrule also rotates around the axle at ordinary times without inflation. When the wedge on the ferrule is pressed down, the ferrule is fixed relative to the axle, and inflation is started. A control rod is additionally arranged between the tire and the wheel rotating shaft, and the control rod stretches out and draws back through the deflation and the fullness of the wheel to control whether the inflator pump inflates. Because the wheel is in a rotating state when being inflated, the inflation switch and the control rod are designed uniquely. The inflating switch is installed on the fixing plate connected with the ferrule, and is connected with the spring leaf and the wedge on the ferrule, the contact on the switch is connected to the middle point of the spring leaf through a rotatable right-angle rod, and the contact is used for being in contact with the control rod. When the control rod for controlling tire deflation extends, the contact is compressed, the spring piece is pulled, the wedge is inserted into the groove of the axle, and the inflation is started; when the control rod is contracted, the contact is hooked back, the wedge is pulled up, and the collar drives the eccentric shaft to rotate around the axle to stop inflating. For motor vehicles without fixed, non-rotating axles, it is possible to attempt to extend a fixed axle from the body outside the wheels. The specific implementation manner is described later with reference to the accompanying drawings.

The invention has the beneficial effects that: when the bicycle is running, the air can be automatically inflated when the tire is insufficient, and the inflation can be automatically stopped after the tire is inflated enough, so that great convenience is provided for a driver.

Detailed Description

In fig. 1, the inflator (3) is connected to the inflation valve (5), and the inflator (3) is fixed to the wheel and is stationary relative to the wheel. The handle end of the inflating piston (4) is connected with the eccentric rotating shaft (7), and the piston (4) can rotate around the eccentric shaft (7). The eccentric rotating shaft (7) and the ferrule (8) are connected into a whole, the spring piece and the wedge (9) are arranged on the ferrule, the wedge is arranged on the spring piece, the ferrule is provided with a hole, and the wedge can penetrate through the ferrule and is inserted into a groove (10) on the axle. The ring (8) rotates around the axle (2) and the wheel at ordinary times, and the piston (4) also rotates with the wheel at ordinary times without inflation. A groove (10) is formed in the axle (2), a wedge (9) can be clamped into the groove (10), the ferrule (8) cannot rotate around the axle (2), at the moment, the piston (4) rotates around the eccentric shaft (7) to realize inflation, and the inflation piston (4) does piston motion once when the wheel rotates for one circle. The C-shaped branch of the ferrule (8) and the midpoint D of the wedge (9) are connected with a switch device for pressing or bouncing the wedge (9), and the switch device is shown in figure 2. The control rod (6) is fixed on the wheel, the B end of the control rod can extend along with the deflation or the air saturation of the tire, and the control rod is used for controlling the contact (11) in the switch in the figure 2, so that the wedge (9) can be inserted into or pulled out of the groove (10). The shape of the B-end is drawn in fig. 3. The end A of the control rod (6) is connected to the tire, and the end B of the control rod can extend to the center or away from the center of the rotating shaft along with the deflation and the foot of the tire so as to control whether the tire needs to be inflated. When the bicycle runs and the wheels rotate, when the tire is full, the ferrule (8) rotates around the axle (2), the inflation piston (4) is static relative to the inflator pump (3), and the ferrule (8) and the piston (4) rotate together with the inflator pump (3) and the control rod (6) along with the wheel without inflation; when the gas is filled, the ferrule (8) and the eccentric rotating shaft (7) do not rotate, the control rod (6) still rotates along with the wheel, and the gas filling piston (4) does piston motion.

The switching device in fig. 2 is perpendicular to the plane of the wheel (1) and the axle (2). (12) Is a fixing plate which is also vertical to the plane of the wheel and is used for embedding the switch device, and the C end and the ferrule (8) are integrated. (14) A right-angle rod on the switch device can rotate around a shaft (14) which is a shaft on the fixed plate (12). E is a movable connection point. The point D is connected to the spring piece middle point of the wedge (9). The contact (11) is positioned at the center of the axle (2) and can be pressed or pulled up, when the contact (11) is pressed down, the spring piece connected with the point D is pulled, the wedge (9) is embedded into the groove (10) on the axle (2), and then the piston (4) rotates around the eccentric shaft (7) to realize inflation. When the contact (11) is pulled up, the spring piece on the wedge (9) is driven to bounce, the wedge (9) is pulled up from the groove (10), the inflation is stopped, and the piston (4), the inflator pump (3) and the ferrule (8) rotate around the axle (2) at ordinary times. The square plate (13) is perpendicular to the fixed plate (12), i.e. parallel to the plane of the axle of the wheel, and has a hole in the middle for passing the rod of the contact (11) so that the rod of the contact (11) remains perpendicular to the plane of the axle and the wheel.

(15) When the tire is deflated, the end A of the control rod (6) is compressed, the end B extends towards the center of the axle (2), the spherical contact (11) is located at the center of the axle (2), and the inclined pressing block (15) compresses the contact (11) to drive the wedge (9) to be embedded into the groove (10) to start inflating. When the contact (11) is pressed down, the control rod (6) rotates around the contact together with the wheel. When the inflation is sufficient, the end A is stretched, the end B is separated from the center of the axle (2), the inclined hook (16) hooks the contact (11), the contact (11) is hooked back, the spring piece on the wedge (9) is driven, the wedge is pulled back, and the inflation is stopped, as shown in (18). (17) The inclined hook bayonet is arc-shaped in a plan view, so that the contact (11) can be hooked more easily. After the inclined hook (17) hooks the contact, the ferrule (8), the control switch on the ferrule, the piston (4) and the control rod (6) rotate around the axle and are not inflated. Under the condition that the wheels rotate, the whole inflation and stop inflation process can be finished without manual additional operation.

The control rod can also be used for other purposes, for example, the control rod is vertically arranged on a floating ball of a water tank, an inclined hook and an inclined pressing block are simplified into two short transverse rods, the floating ball descends when water is low, and an upper rod at the end A pulls a lower switch; when the water is full, the floating ball rises, and the lower rod at the A end pushes up the switch. The water tank can be automatically filled with water.
