[0023] See attached document Figure 1 -Appendix Figure 5 This embodiment provides a quick-release safety protection component for the end effector of a robotic arm. A detachable adapter block 200 and a slanted connecting block 400 are provided between the robotic arm and the physiotherapy tool head. The slanted connecting block 400 connects to the physiotherapy tool head. The contact surfaces of the adapter block 200 and the slanted connecting block 400 are angled and equipped with a locking device. This allows the physiotherapy tool head to tilt upwards and away from the human body when the slanted connecting block 400 is unlocked from the adapter block 200. Specifically, unlocking involves releasing the locking device at the connection point between the slanted connecting block 400 and the adapter block 200, allowing relative movement between them. This ensures that in case of danger or malfunction, the physiotherapy tool head can be moved away from the human body in the working area, preventing harm to the user and enhancing safety.
[0024] The contact surfaces of the adapter block 200 and the inclined top connecting block 400 are tilted at an angle of 20° to 70°. When the angle is too low, the movement path of the physiotherapy tool head is too low, which may result in secondary contact with the human body and cannot completely avoid danger. When the angle is too high, it is inconvenient to operate.
[0025] The adapter block 200 includes an adapter block housing 200 with an inclined surface, the inclined surface being the side that contacts the inclined top connecting block 400. An adapter block clip and component 230 are provided on the inclined surface. The side of the inclined top connecting block 400 that contacts the adapter block 200 is provided with a connecting block clip and groove 420 for accommodating and fitting the adapter block clip and component 230. The size and shape of the connecting block clip and groove 420 are adapted to the size and shape of the adapter block clip and component 230.
[0026] The connecting block and slot 420 have a wedge-shaped groove structure, and the cross-section of the connecting block and slot 420 gradually increases along the direction in which the adapter block and component 230 is pulled out. This effectively prevents the physiotherapy tool head from moving downwards under its own gravity and causing damage after being unlocked.
[0027] The adapter block 200 and the inclined top connecting block 400 are connected by interlocking clips and slots and clips and blocks, and are locked by locking assembly 500.
[0028] The locking assembly 500 includes a connecting rod 510 and a latch and block 520. The connecting block latch and slot 420 has a connecting block locking hole 430, and the corresponding area of the adapter block latch and component 230 has an adapter block locking hole 220. The latch and block 520 can be simultaneously inserted into the connecting block locking hole 430 and the adapter block locking hole 220 for locking. The latch and block 520 has a certain curvature so that the latch and block 520 can disengage from the connecting block locking hole 430 and the adapter block locking hole 220.
[0029] The inclined top connecting block 400 is provided with a connecting block mounting hole 450 for accommodating the locking assembly 500. The end of the clip and block 520 is provided with a spring 530. The sum of the length of the spring 530 in its compressed state and the length of the connecting rod 510 is greater than the depth of the connecting block mounting hole 450 so that one end of the connecting rod 510 protrudes from the connecting block mounting hole 450.
[0030] When unlocking is required, press the connecting rod 510 and compress the spring 530. The clip and block 520 disengage from the locking hole 430 of the connecting block and the locking hole 220 of the adapter block. At this time, the adapter block 200 and the inclined connecting block 400 are locked in contact and can move freely. By applying a contact force along the inclined surface of the inclined connecting block 400, the inclined connecting block 400 is tilted upward, causing the lower physiotherapy working head to move away from the human body.
[0031] The end of the inclined connecting block 400 away from the adapter block 200 is detachably connected to an end connector 800, which is fixedly connected to the physiotherapy tool head. The connection method of the end connector 800 to the physiotherapy tool head is a common structure in the prior art, so it will not be described in detail in this application.
[0032] The inclined top connecting block 400 is provided with a connecting block clip and component 460 at one end away from the adapter block 200. The end connecting seat 800 is provided with a connecting seat clip and groove 820 on the contact surface with the inclined top connecting block 400 for accommodating and fitting the connecting block clip and component 460. The connecting seat clip and groove 820 has a wedge-shaped groove structure, and the cross-section of the connecting seat clip and groove 820 gradually increases along the direction in which the connecting block clip and component 460 is pulled out.
[0033] The end connector 800 includes a connector housing 810, on which a connector mounting hole 850 is provided. A locking component 700 is provided in the connector mounting hole 850. The locking component 700 includes a connecting rod 710 and a locking block 720. The connector locking slot 820 is provided with a connector locking hole 830. The corresponding area of the connector locking component 460 is provided with a connector locking hole. The locking block 720 can be simultaneously inserted into the connector locking hole 830 and the connector locking hole for locking.
[0034] The locking assembly 700 is provided with a spring 730 at its end. The sum of the length of the spring 730 in its compressed state and the length of the connecting rod 710 is greater than the depth of the connecting seat mounting hole 850, so that one end of the connecting rod 710 protrudes from the connecting seat mounting hole 850.
[0035] By pressing the connecting rod 710, the connecting rod 710 moves and causes the card and block 720 to disengage from the locking hole 830 of the connecting seat and the locking hole of the connecting block. The shape of the card and block 720 is a common type of card and block structure with a certain curvature in the prior art, which is easy to disengage and move. After unlocking is completed, the end connecting seat 800 can move the physiotherapy worktable in the horizontal direction, and cooperate with the tilt direction for better disassembly and movement.
[0036] The connecting block locking hole 430 is provided with a connecting block fixing buckle 440. The connecting block fixing buckle 440 covers a certain area of the connecting block locking hole 430 to limit the card and block 520 and prevent the card and block 520 from being too embedded in the connecting block locking hole 430.
[0037] Similarly, the mounting hole 850 of the connecting seat is provided with a connecting seat fixing buckle 840, and the locking hole 830 of the connecting seat covers a certain area of the mounting hole 850 of the connecting seat to limit the position of the card and the second block 720, and prevent the card and the second block 720 from being too embedded in the locking hole 830 of the connecting seat.
[0038] This embodiment also includes a human body data acquisition component 300, which is a depth camera or other human body surface image acquisition component.
[0039] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
