[0003] At present, most of the existing touch mechanisms adopt a flat or curved surface design. In the actual use of the sensing mechanism, since the touch received by the unmanned vehicle is not transmitted from a fixed direction, and the existing touch sensing mechanism is limited by the structure and design, it is impossible to achieve better connection and touch sensing for the outer panels at multiple angles, resulting in poor sensing effect of the touch sensing mechanism, which will in turn affect the normal operation of the unmanned vehicle, so it is necessary to improve this. Utility Model Content

[0008] As a preferred technical solution of the utility model, a card slot is respectively provided on the left and right sides of the front end of the scraper, and a card block is movably sleeved inside the card slot.

[0009] As a preferred technical solution of the utility model, the two limit rods are respectively provided with circular grooves located below the clamping grooves, the top ends of the circular grooves are movably sleeved with connecting blocks, and the top ends of the connecting blocks are fixedly connected to the bottom ends of the clamping blocks.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figures 1 to 7 As shown, the utility model provides a multi-angle touch sensing mechanism, including a carrier 1, a ball head connecting rod 2 is movably sleeved inside the carrier 1, a touch plate 3 is movably sleeved on the left side of the outer surface of the ball head connecting rod 2, a baffle 4 is fixedly sleeved on the left end of the ball head connecting rod 2, the outer surface of the baffle 4 is movably sleeved on the inner surface of the touch plate 3, a circular plate 5 is fixedly sleeved on the right side of the outer surface of the ball head connecting rod 2, a pressure spring 6 is fixedly installed on the left end of the circular plate 5, the other end of the pressure spring 6 is fixedly connected to the right end of the touch plate 3, a torque spring 7 is fixedly sleeved on the right side of the bottom end of the ball head connecting rod 2, the torque spring 7 is movably sleeved on the inner surface of the carrier 1, a touch switch 8 is movably installed on the upper and lower sides of the front end of the carrier 1, and a fixing plate 9 is fixedly installed on the left and right sides of the front end of the carrier 1, an arch spring 10 is movably sleeved inside the fixing plate 9, and the outer surface of the arch spring 10 is movably connected to the outer surface of the touch plate 3.

[0025] When the touch plate 3 is subjected to force from the front, the touch plate 3 will move along the outer surface of the ball head connecting rod 2 toward the carrier 1, so that the pressure spring 6 will be deformed by the internal pressure. When the touch plate 3 is subjected to force from the side, the torque spring 7 will be subjected to force and move laterally together with the ball head of the ball head connecting rod 2. At the same time, the arch spring 10 will be deformed by the internal pressure, thereby causing the touch plate 3 to move. Since the touch switch 8 is evenly distributed on the upper and lower sides of the front end of the carrier 1, the touch switch 8 will be pressed to close as the touch plate 3 moves, thereby achieving the purpose of touch sensing. The cooperation of various mechanisms enables the sensing mechanism to provide feedback for forces at multiple angles and in different directions.

[0026] Among them, the left and right sides of the front end of the touch plate 3 are fixedly installed with limit rods 11, the number of limit rods 11 is two, and the upper and lower ends of the two limit rods 11 are fixedly sleeved with stoppers 12, and the outer surface of the stopper 12 is fixedly connected to the outer surface of the touch plate 3.

[0027] The cooperation between the limiting rod 11 and the stopper 12 will play a limiting role.

[0028] Among them, the bottom of the outer surface of the two limit rods 11 is movably connected with a scraper 13, the rear end of the scraper 13 is movably connected to the front end of the touch plate 3, the outer surface of the scraper 13 is movably connected to the outer surface of the block 12, and a handle 14 is fixedly installed in the middle of the front end of the scraper 13.

[0029] When the scraper 13 moves along the outer surface of the limiting rod 11 , the outer surface of the contact plate 3 will be cleaned.

[0030] The left and right sides of the front end of the scraper 13 are respectively provided with clamping grooves 15 , and a clamping block 16 is movably sleeved inside the clamping groove 15 .

[0031] Due to the presence of the locking groove 15 and the locking block 16 , the position of the scraper 13 will be locked.

[0032] The two limiting rods 11 are respectively provided with circular grooves 17 below the clamping grooves 15 , and the top of the circular grooves 17 is movably sleeved with a connecting block 18 , and the top of the connecting block 18 is fixedly connected to the bottom of the clamping block 16 .

[0033] When the clamping block 16 moves, it will bring the connecting block 18 to move downward along the inner surface of the circular groove 17 .

[0034] A connecting spring 19 is fixedly mounted on the bottom end of the connecting block 18 , and the other end of the connecting spring 19 is fixedly connected to the bottom end inside the circular groove 17 .

[0035] When the connecting block 18 moves, the connecting spring 19 will be compressed, and under the restoring action of the connecting spring 19, the connecting block 18 will be forced to return to its original position.

[0036] The block 16 has a hemispherical shape.

[0037] Due to the hemispherical design of the block 16 , when the scraper 13 moves, the inner wall of the slot 15 squeezes the outer surface of the block 16 , squeezing the block 16 to move downward.

[0038] The working principle and use process of this utility model:

[0039] Firstly, when the front side of the touch plate 3 is subjected to force, it will move toward the carrier 1 along the outer surface of the ball head connecting rod 2 and compress the pressure spring 6. When the side of the touch plate 3 is subjected to force, the torque spring 7 will be subjected to force and will move sideways together with the ball head of the ball head connecting rod 2. When the touch plate 3 is subjected to force and moves toward the carrier 1, the arch spring 10 will be subjected to internal pressure and deform. Since the touch switch 8 is evenly distributed on the upper and lower sides of the front end of the carrier 1 and is located between the carrier 1 and the touch plate 3, the touch switch 8 will be pressed to close as the touch plate 3 moves, thereby achieving the purpose of touch sensing. When the external force is eliminated, the touch plate 3 will return to its original state under the restoring action of the pressure spring 6, the torque spring 7 and the arch spring 10. The cooperation of each mechanism enables the sensing mechanism to provide feedback for forces in multiple angles and directions, which is more efficient and convenient.

[0040] When the outer surface of the touch plate 3 needs to be cleaned, the handle 14 is pushed to make the scraper 13 move upward along the outer surface of the touch plate 3 and the limit rod 11. At this time, as the scraper 13 moves, the inner wall of the groove 15 will squeeze the outer surface of the block 16, so that the block 16 moves down along the inner surface of the circular groove 17 with the connecting block 18 and compresses the connecting spring 19. When the scraper 13 and the block 16 are separated, under the restoring action of the connecting spring 19, the connecting block 18 will restore to its original position with the block 16. As the scraper 13 continues to move, the dirt attached to the outer surface of the touch plate 3 will be scraped and cleaned, thereby improving the convenience of using the sensing mechanism.
