Description

Technical Field

[0001] This utility model relates to the field of quick-release technology, and more specifically, to a quick-release structure. Background Technology

[0002] With the advancement of technology, various convenient structures have gradually emerged. In current massage robots, the massage head and robotic arm are directly connected, and most existing massage heads and robotic arms are fixed with screws. Typically, one massage robot corresponds to one massage head, resulting in limited product functionality. Some robot products offer replaceable massage heads, but disassembling and assembling the massage head requires tools such as screwdrivers, making replacement laborious and leading to a poor user experience. Utility Model Content

[0003] Therefore, this utility model embodiment provides a quick-release structure, making it more convenient and faster to disassemble the massage head.

[0004] To address the aforementioned problems, this utility model provides a quick-release structure for use with a robot, which is detachably connected to a massage head. The quick-release structure includes: a base for connecting to the robot, and the base has an elastic limiting portion; a connecting component, which is located on the base, and the elastic limiting portion is at least partially located within the connecting component; a control component, which is sleeved on the connecting component and can drive the connecting component to rotate; and multiple limiting sliding components, which are located on the control component, and a limiting seat component is provided on the side of the multiple limiting sliding components away from the control component, the limiting seat component being used to limit the sliding position of the multiple limiting sliding components; wherein, in the initial state, the multiple limiting sliding components are locked to the massage head, and the sliding of the multiple limiting sliding components is controlled by rotating the control component to unlock them.

[0005] Compared with existing technologies, the technical effects achieved by this solution are as follows: By controlling the rotation of the control component to drive the linkage of multiple limiting sliding components, the massage head and the robotic arm can be quickly locked and unlocked, completely eliminating the traditional screw fixing method. Users can complete the replacement operation by hand without tools, greatly improving the efficiency of disassembly and assembly and the convenience of use. The elastic limiting part and the limiting seat assembly work together to ensure that the massage head remains stably locked when subjected to multidimensional vibration loads in the initial state, preventing accidental dislodgement; while the controlled sliding path design of the limiting sliding components during the unlocking process effectively prevents mechanical jamming caused by misoperation, significantly improving structural reliability and expanding the robot's flexibility in adapting to different functional massage heads.

[0006] In one embodiment of this utility model, the quick-release structure further includes: a connecting component having a plurality of first protrusions arranged around the connecting component; a control component having a plurality of second protrusions; wherein, when the control component is fitted onto the connecting component, a first elastic member is provided between a first protrusion and a second protrusion.

[0007] Compared with existing technologies, the technical effects achieved by this solution are as follows: A first elastic element is installed within the accommodating space formed by the staggered arrangement of the first and second protrusions. This allows the control component to generate a phased damping feedback force during rotation. Users can clearly perceive the critical point of the rotation angle through touch, preventing overload damage to the internal mechanism due to excessive rotation. The circumferential distribution design of the protrusions evenly transmits torque to the connecting components, eliminating localized stress concentration and extending the service life of the quick-release structure. Simultaneously, the compression and rebound characteristics of the elastic element provide an automatic reset tendency for the control component, ensuring that each component quickly returns to its initial locked position after unlocking, improving operational continuity and the human-machine interface experience.

[0008] In one embodiment of this utility model, the quick-release structure further includes: the control component is provided with a plurality of first slide grooves; each limiting slide component is connected to a first slide groove and a limiting seat component respectively, so that the sliding of the limiting slide component is restricted.

[0009] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: by setting the limiting sliding component to be restricted by the first slide groove and the limiting seat component, the limiting sliding component is guided more stably when sliding, which enables the limiting sliding component to be unlocked and fixed better, ensuring the normal unlocking of the massage head and making it more convenient and quick to use.

[0010] In one embodiment of this utility model, the quick-release structure further includes: each limiting sliding component is provided with a limiting post, and the two ends of the limiting post are respectively connected to the first sliding groove and the limiting seat component.

[0011] Compared with existing technologies, the technical effects achieved by this solution are as follows: the two ends of the limiting post are anchored to the first slide groove and the limiting seat assembly, respectively, forming a through-type force transmission skeleton. This directly converts the axial tensile force applied by the massage head into the shear resistance of the limiting post, avoiding the risk of bending and breakage caused by the cantilever beam design of traditional snap-fit ​​structures. The high rigidity of the post structure suppresses the resonance amplification phenomenon caused by high-frequency vibration, ensuring gapless shaking in the locked state. At the same time, the precise matching of the diameter of the limiting post and the width of the slide groove provides radial positioning constraints while maintaining low-friction sliding, ensuring the accuracy of synchronous operation of multiple sliding components.

[0012] In one embodiment of this utility model, the quick-release structure further includes a support ring fitted on the portion of each limiting post that connects the first sliding groove and the limiting seat assembly.

[0013] Compared with existing technologies, the technical effects achieved by this solution are as follows: the support ring, fitted onto the force-bearing contact area of ​​the limiting post, significantly reduces the coefficient of sliding friction through the self-lubricating properties of the polymer material, eliminating abnormal noise and wear particles generated by direct metal-to-metal contact. The elastic deformation capability of the support ring compensates for coaxiality deviations caused by machining and assembly errors, allowing the limiting post to slide smoothly even in non-ideal alignment states; its buffering characteristics also absorb the instantaneous impact energy of the massage head, suppressing the intensity of vibration transmission to the robot body, thus possessing the dual advantages of improving mechanical life and reducing operating noise.

[0014] In one embodiment of this utility model, the quick-release structure further includes: the limiting seat assembly is provided with a plurality of first mounting positions, each first mounting position is provided with a limiting sliding component, and each first mounting position is connected to the interior of the limiting seat assembly, so that the limiting sliding component can be partially extended.

[0015] Compared with existing technologies, the technical effects achieved by this solution are as follows: The cavity design of the first mounting position provides full-enclosed protection for the limiting sliding component, preventing external dust from entering the precision sliding pair and reducing the jamming failure rate caused by environmental pollutants. The communication channel between the mounting position and the limiting seat component allows the third protrusion to extend into the working area as needed, realizing directional triggering of the locking function in a compact space; the precise matching of the channel size and the slider stroke forms a mechanical stroke termination limit, preventing permanent deformation caused by over-compression of the elastic element and ensuring the consistency of the initial unlocking force even after long-term use.

[0016] In one embodiment of this utility model, each limiting sliding component includes: a slider, the slider having a second groove and a third protrusion; wherein, a limiting post is provided through the second groove, and the third protrusion can protrude into the limiting seat component when the slider slides.

[0017] Compared with the existing technology, the technical effects achieved by adopting this technical solution are as follows: by setting a limiting post to penetrate the second sliding groove, the limiting post can better drive the limiting sliding component to slide. At the same time, a third protrusion is set to better lock the massage head, ensuring the stability of the massage head.

[0018] In one embodiment of this utility model, each limiting sliding component further includes: multiple placement slots, the multiple placement slots being disposed on the slider, and each placement slot being provided with a second elastic member, the second elastic member extending out of the slider and connecting to the first mounting position.

[0019] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: by setting a placement groove in conjunction with a second elastic element, the slider can be reset by the elastic force of the second elastic element, while ensuring that the practicality of the limiting sliding component is stronger and can provide better locking. At the same time, the second elastic element can also avoid collision between the limiting sliding component and the limiting seat component, thereby improving the overall safety and service life.

[0020] In one embodiment of this utility model, the quick-release structure further includes: a guide boss on the base, and a third elastic member on the guide boss; a top block connected to the third elastic member, the top block being at least partially located within the connecting component and engaged by the connecting component.

[0021] Compared with existing technologies, the technical effects achieved by this solution are as follows: the third elastic element on the guide boss pushes the top block and the connecting assembly to form a secondary locking mechanism, establishing a redundant protection mechanism in addition to the main locking of the limiting sliding assembly, preventing the massage head from accidentally falling off even if a single mechanism fails. The conical guide design of the top block automatically compresses the elastic element to make way when the massage head is inserted, eliminating the need for manual intervention during assembly; the locking structure of the connecting assembly limits the rebound stroke of the top block, ensuring that it forms a rigid contact with the massage head in the working position, effectively absorbing axial impact loads and suppressing high-frequency micro-vibrations.

[0022] In one embodiment of this utility model, the quick-release structure further includes: a fourth protrusion on the side of the connecting component near the top block, the fourth protrusion being used to limit the lifting position of the top block; and an asymmetrical limiting part on the limiting seat assembly, the asymmetrical limiting part being used to cooperate with and fix the massage head.

[0023] Compared with existing technologies, the technical effects achieved by this solution are as follows: The fourth protrusion acts as a mechanical stop for the movement of the top block, precisely limiting the lifting height within a safe threshold and preventing the third elastic element from failing due to excessive compression and plastic deformation. The hardened surface of the protrusion withstands the cyclic impact load of the top block, and its arc-shaped edge design guides the top block to slide into the locking position, generating tactile and auditory feedback signals. By setting an asymmetrical limiting part for anti-reverse assembly with the massage head, the ease of assembly is improved.

[0024] By adopting the technical solution of this utility model, the following technical effects can be achieved: (1) By controlling the rotation of the component to drive multiple limiting sliding components in linkage, the massage head and the robot arm can be quickly locked and unlocked, completely eliminating the traditional screw fixing method. Users can complete the replacement operation by hand without tools, which greatly improves the efficiency of disassembly and assembly and the convenience of use. The elastic limiting part and the limiting seat component work together to ensure that the massage head remains stable and locked when subjected to multidimensional vibration load in the initial state, avoiding accidental detachment; while the controlled sliding path design of the limiting sliding component during the unlocking process effectively prevents mechanical jamming caused by misoperation, significantly improving the structural reliability and expanding the robot's flexibility to adapt to different functional massage heads.
