[0028] See also Figures 1 to 9 The present invention provides a technical solution: a wearable pet AR glasses that prevents falling, such as Figure 3 and Figure 4 As shown in the figure, it includes an AR glasses host 1, which is provided with a gyroscope, an acceleration sensor, a camera, a lens, a projection module and a battery, etc., and the inside of the AR glasses host 1 is respectively provided with control side warehouses 2 near the two sides, and a sliding puller 3 is provided in the control side warehouse 2. A driving cylinder 4 for pushing the sliding puller 3 to move is provided on one side of the sliding puller 3. The driving cylinder 4 is a cylinder structure in the prior art, and a reset compression spring 5 is provided on the side of the sliding puller 3 away from the driving cylinder 4. A head strap 6 is connected to the sliding puller 3. When the driving cylinder 4 is extended, the head strap 6 can be tightened by pushing the sliding puller 3 to move. A lower jaw strap 7 and a control back warehouse 8 are provided on the head strap 6. The control back warehouse 8 is provided with a gas control mechanism inside. The gas control mechanism can use the activities of the pet to generate positive-pressure gas and input it into the driving cylinder 4. The gas control mechanism can automatically discharge the positive-pressure gas after the pet stops moving.

[0029] like Figure 6 and Figure 7As shown in , the pneumatic control mechanism includes a fulcrum fixed shaft 801, a fulcrum rotating sleeve 802, a long arm connecting rod 803 and a counterweight lead block 804. The fulcrum fixed shaft 801 is fixedly installed at the inner wall surface position of the control back warehouse 8, and the fulcrum rotating sleeve 802 is rotatably sleeved on the outside of the fulcrum fixed shaft 801. The outside of the fulcrum rotating sleeve 802 is fixedly provided with a long arm connecting rod 803, and the end of the long arm connecting rod 803 is fixedly provided with a counterweight lead block 804. Rebound paddles 805 are respectively provided on both sides of the counterweight lead block 804, and the rebound paddles 805 are fixedly installed with the inner wall surface of the control back warehouse 8. A toggle card frame 806 is fixedly provided on the fulcrum rotating sleeve 802, and a card frame inner shaft 807 is inserted and limited in the toggle card frame 806.

[0030] A reciprocating plate 808 is fixedly provided at the end of the inner shaft 807 of the card frame, and a positioning wall frame 809 is fixedly provided on the inner wall surface of the control back warehouse 8. The reciprocating plate 808 is limited and inserted through the positioning wall frame 809. When the counterweight lead block 804 swings back and forth, the reciprocating plate 808 can be driven to reciprocate in a straight line by toggling the card frame 806. The force arm distance between the inner shaft 807 of the card frame and the fulcrum fixed shaft 801 is smaller than the force arm distance between the counterweight lead block 804 and the fulcrum fixed shaft 801, and the lever principle is used to increase the driving thrust of toggling the card frame 806.

[0031] A piston portion 810 is fixedly provided at one end of the reciprocating plate 808, and a fixed cylinder body 811 is fixedly provided on the inner wall surface of the control back warehouse 8. The piston portion 810 is located inside the fixed cylinder body 811 and is in air-tight contact with the inner wall surface of the fixed cylinder body 811. A buffer air storage chamber 812 is fixedly provided on the inner wall surface of the control back warehouse 8. A first one-way valve 813 is provided between the end of the fixed cylinder body 811 and the buffer air storage chamber 812. A right-angle air inlet cavity 814 is provided at the end of the fixed cylinder body 811. The other end of the right-angle air inlet cavity 814 is connected to the outside, and a second one-way valve 815 is provided in the right-angle air inlet cavity 814.

[0032] The first one-way valve 813 allows the airflow in the fixed cylinder 811 to flow unidirectionally into the buffer air storage chamber 812, and the second one-way valve 815 allows the external airflow to flow unidirectionally into the fixed cylinder 811. The buffer air storage chamber 812 is connected to an output air nozzle 816, and the output air nozzle 816 is connected to the driving cylinder 4 through an air pipe. The air pipe between the output air nozzle 816 and the driving cylinder 4 is hidden in the head strap 6. When the head strap 6 has telescopic elasticity, the air pipe can be bent to adapt to the elastic telescopic stroke of the head strap 6.

[0033] An annular sleeve cavity 817 is opened in the side wall of the fixed cylinder body 811, and the annular sleeve cavity 817 surrounds and wraps the internal cylindrical cavity of the fixed cylinder body 811. The outside of the annular sleeve cavity 817 is connected to a piston cylinder body 818, and a fixed support 819 is fixedly provided at the end of the piston cylinder body 818. The fixed support 819 is fixedly installed with the buffer air storage chamber 812, and a balancing air groove 820 is opened through the end of the piston cylinder body 818 near the position of the fixed support 819.

[0034] A piston column 821 is provided inside the piston cylinder 818, and the piston column 821 is in air-tight contact with the piston cylinder 818. A sealing column 822 is fixedly provided on the piston column 821. An exhaust cavity 823 is penetrated through the fixed support 819, and the sealing column 822 is inserted into the exhaust cavity 823 and is in air-tight contact with the exhaust cavity 823. A beam gas path 824 is opened in the fixed support 819, and one end of the beam gas path 824 is connected to the exhaust cavity 823, and the other end is connected to the inner cavity of the buffer gas storage chamber 812.

[0035] A push-to-exhaust valve 825 is embedded in the control back chamber 8, and the push-to-exhaust valve 825 is connected to the buffer air storage chamber 812. When the push-to-exhaust valve 825 is pressed, the compressed gas in the buffer air storage chamber 812 can be released. The head strap 6 can be quickly relaxed by the set push-to-exhaust valve 825. When the push-to-exhaust valve 825 is pressed, the air pressure in the buffer air storage chamber 812 can be forced to be discharged, so that the driving cylinder 4 contracts and resets. At this time, the head strap 6 is directly relaxed, which is convenient for manually removing the pet's AR glasses under any circumstances. A breathing window 826 is opened on the surface of the control back chamber 8.

[0036] A limit slot 201 is provided on the inner surface of the control side bin 2, and the sliding puller 3 is limitedly set in the limit slot 201 and slides along the length direction of the limit slot 201. A strap groove 202 is provided through the surface of the control side bin 2, and the head strap 6 is inserted through the strap groove 202.

[0037] When the wearable pet AR glasses of the present invention are used, the AR glasses host 1 is covered on the eyes of a pet such as a dog, the head strap 6 is bound to the dog's head, and the chin strap 7 is bound to the dog's chin.

[0038] like Figure 5 As shown in FIG, when the pet moves, for example, by shaking its head left and right, the lead weight 804 can be driven to swing back and forth. Figure 7 As shown in , at this time, the card frame 806 is moved to cooperate with the inner shaft 807 of the card frame to drive the reciprocating plate 808 to reciprocate linearly, thereby causing the piston part 810 to reciprocate inside the fixed cylinder body 811.

[0039] by Figure 7For example, when the piston part 810 moves to the right, the gas in the fixed cylinder 811 will be pressed into the buffer air storage chamber 812 through the first one-way valve 813. When the piston part 810 moves to the left, the external gas will be sucked into the fixed cylinder 811 through the second one-way valve 815. This cycle can keep the buffer air storage chamber 812 continuously inflated.

[0040] In the initial stage of inflation of the buffer gas storage chamber 812, some gas will be discharged through the beam gas path 824, but the diameter of the beam gas path 824 is small enough, and the exhaust flow rate is much smaller than the gas input flow rate of the fixed cylinder 811. The air pressure in the overall buffer gas storage chamber 812 continues to increase, and with the friction between the piston part 810 and the fixed cylinder 811, the fixed cylinder 811 is heated up, and then the annular sleeve cavity 817 is heated up, and the gas in the annular sleeve cavity 817 expands, pushing the piston column 821 downward, so that the sealing column 822 is inserted into the exhaust cavity 823 to block and close the opening of the beam gas path 824. At this time, the beam gas path 824 is automatically closed, and the exhaust of the beam gas path 824 is stopped.

[0041] Since the buffer air storage chamber 812 is connected to the output air nozzle 816, the air pressure in the buffer air storage chamber 812 enters the driving cylinder 4 through the output air nozzle 816 and the air pipe. Figure 4 As shown in the figure, the driving cylinder 4 is extended, pushing the sliding puller 3 to move, and the head strap 6 is pulled and dragged into the control side compartment 2. At this time, the head strap 6 will be further tightened, so that when the pet moves, the head strap 6 will be automatically tightened to reduce the probability of the pet AR glasses falling off.

[0042] When the pressure in the buffer air storage chamber 812 rises to a certain level, the piston part 810 can no longer squeeze the gas into the buffer air storage chamber 812. At this time, with the movement of the pet, the counterweight lead block 804 can only swing slightly, driving the piston part 810 to move slightly axially back and forth within the elastic range of the gas. At this time, the small axial reciprocating movement of the piston part 810 will not compress the gas into the buffer air storage chamber 812, but only make the gas pressure in the fixed cylinder body 811 fluctuate within the positive pressure range, that is, the fixed cylinder body 811 is always in a positive pressure state, but the positive pressure fluctuates, and air will no longer be sucked in through the second one-way valve 815. At this time, the active friction of the piston part 810 can maintain the temperature of the annular sleeve cavity 817, so that the beam gas path 824 remains closed.

[0043] When the pet is resting for a long time, as the temperature of the fixed cylinder 811 and the annular sleeve cavity 817 decreases, the gas in the annular sleeve cavity 817 decreases and contracts, the piston cylinder 821 and the blocking cylinder 822 move up and reset, and the end of the beam gas path 824 is reconnected with the outside world. At this time, the gas in the buffer gas storage chamber 812 is slowly discharged through the beam gas path 824, so that the pressure in the beam gas path 824 gradually decreases, and under the elastic force of the reset compression spring 5, the cylinder 4 is driven to contract and reset, so that the head strap 6 is gradually relaxed.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
