Description

Technical Field

[0001] This application relates to the field of pet products, and in particular to a pet door clutch device and a litter box. Background Technology

[0002] With the development of smart pet devices, the automation level of pet gates is constantly improving, but the resulting malfunctions cannot be ignored. Currently, most pet gates on the market often become jammed or abnormally locked when malfunctioning. This not only restricts the pet's normal movement, but more seriously, it may cause accidental injury. For example, when a pet is eager to pass through the gate, a jammed gate may crush parts of the pet's body.

[0003] While existing pet door designs incorporate various functionalities, their safety features in case of malfunctions are relatively weak. In the event of electrical failures or mechanical damage, pet doors lack effective automatic unlocking mechanisms to prevent harm to pets. Utility Model Content

[0004] In view of the above problems, this utility model proposes a pet door clutch device, which aims to solve the technical problem that pet doors can easily cause harm to pets when they are jammed or abnormally locked.

[0015] In one embodiment, the direction of the elastic restoring force of the reset member is set at an angle to the first direction, and the locking part can move relative to the mating part along the parallel direction of the first connector and the second connector to switch the locking position and the unlocking position.

[0016] Furthermore, the locking part and the reset member are arranged along the parallel direction, the direction of the elastic restoring force of the reset member extends along the parallel direction, and the end of the reset member away from the locking part is fixed to the first connecting member.

[0025] In the locked position, the first connector and the second connector of the pet door clutch device move synchronously under the action of the drive member; in the unlocked position, the first connector of the pet door clutch device can slide relative to the second connector of the pet door clutch device.

[0026] This invention provides a pet door clutch device. The locking part and the mating part work together to allow the first and second connecting parts to move synchronously under the action of the driving part. Furthermore, the locking part's movable or deformable nature relative to the mating part allows the user to easily switch the locking part to the unlocked position even if unexpected factors cause mechanical parts to shift or malfunction during use. This allows the second connecting part to slide relative to the first connecting part along the second guide rail. Thus, even if the driving part or other related components malfunction, the door will not easily become completely jammed, and the pet will still have some room to move, entering and exiting by pushing the door, maximizing the pet's unimpeded daily activities and allowing it to freely move between the two sides of the pet door.

[0052] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0053] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the meaning of "and / or" throughout the text is to include three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution that simultaneously satisfies both A and B.

[0054] This utility model proposes a pet door clutch device.

[0055] In this embodiment of the utility model, please refer to Figures 1 to 20The pet door clutch device 100 includes a guide member 10, a first connector 20, a second connector 30, and a locking structure 40. The guide member 10 includes a first guide rail 11 and a second guide rail 12, both extending in a first direction and arranged side-by-side. The first connector 20 is movable along the first guide rail 11. The second connector 30 is movable along the second guide rail 12, and a mating portion 31 is provided on the side of the second connector 30 facing the first connector 20. One of the first connector 20 and the second connector 30 is used to connect to the door body 60, and the other is used to connect to the drive member 61. The locking structure 40 includes a locking portion 41 installed on the first connector 20 and opposite to the mating portion 31. The locking portion 41 is movable or deformable relative to the mating portion 31 to have a locking position engaged with the mating portion 31 and an unlocking position disengaged from the mating portion 31.

[0056] In the locked position, the first connector 20 and the second connector 30 move synchronously under the action of the drive member 61; in the unlocked position, the second connector 30 can slide relative to the first connector 20 along the second guide rail 12.

[0057] In this embodiment, the guide 10 (first guide rail 11 and second guide rail 12) provides a precise guide path for the movement of the first connector 20 and the second connector 30, defines their movement direction, and ensures that each component operates stably in the predetermined direction.

[0058] The first connector 20 or the second connector 30 can move along the guide 10 and serve to connect the door body 60 or the drive unit 61, making it an important component that enables the pet door clutch device 100 to automatically disengage when a malfunction such as jamming occurs.

[0059] The locking structure 40 controls the connection and unlocking between the first connector 20 and the second connector 30. The interaction (locking and unlocking) between the locking part 41 and the mating part 31 determines whether the connectors move synchronously. When the locking part 41 is in the locked position, the first connector 20 and the second connector 30 move together; while in the unlocked position, the second connector 30 can slide independently of the first connector 20. The locking part 41 is movable or deformable relative to the mating part 31 to have a locked position engaged with the mating part 31 and an unlocked position disengaged from the mating part 31.

[0060] The locking portion can be spherical, elongated, etc., and its shape is not limited here. In some embodiments, the outer surface of the locking portion has strong friction to enhance the locking effect between the locking portion and the mating portion. The mating portion can be a groove, notch, or protrusion, etc., and is not limited here.

[0061] This invention provides a pet door clutch device 100. The pet door clutch device 100, through the cooperation of the locking part 41 and the mating part 31, allows the first connecting member 20 and the second connecting member 30 to move synchronously under the action of the driving member 61. Simultaneously, due to the movable or deformable nature of the locking part 41 relative to the mating part 31, even if unexpected factors cause mechanical parts to shift or malfunction during use, the user can easily switch the locking part 41 to the unlocked position, allowing the second connecting member 30 to slide relative to the first connecting member 20 along the second guide rail 12. Thus, even if the driving member 61 or other related components malfunction, the door 60 will not easily be completely jammed, and the pet will still have some room to move, entering and exiting by pushing the door 60, etc., maximizing the protection of the pet's daily activities and allowing it to freely move between the two sides of the pet door.

[0062] Furthermore, please be sure to refer to... Figures 1 to 16 The locking structure 40 also includes a reset member 42 installed on the first connector 20. The locking part 41 is connected to the reset member 42 and moves relative to the mating part 31 through the reset member 42 to switch the locking position and the unlocking position.

[0063] In this embodiment, the reset member 42 includes, but is not limited to, a spring, a component made of an elastic material, or other structures that can return to their original position. The locking part 41 switches between locked and unlocked positions by the movement of the reset member 42. In case of a malfunction, the force of the reset member 42 can be overcome manually or automatically, causing the locking part 41 to enter the unlocked position. When the malfunction is resolved or normal operation needs to be restored, the reset member 42 pulls the locking part 41 back from the unlocked position to the locked position.

[0064] In some embodiments, refer to Figures 5 to 9 The direction of the elastic restoring force of the reset member 42 is set at an angle to the parallel direction of the first connector 20 and the second connector 30. The locking part 41 can rotate relative to the mating part 31 through the reset member 42 to switch the locking position and the unlocking position.

[0065] Referring to the second to sixth embodiments, the direction of the elastic restoring force of the reset member 42 is set at an angle to the parallel direction of the first connecting member 20 and the second connecting member 30. When the locking part 41 rotates due to external forces or other factors, deviating from its original locked or unlocked position, the reset member 42, by virtue of the elastic restoring force in the angled direction, applies a resultant force to the locking part 41 that has both a component force along the parallel direction and a component force perpendicular to the parallel direction. The component force along the parallel direction helps control the linear movement of the locking part 41 when rotating to switch positions, while the perpendicular component force can play a stabilizing and limiting role from the side, preventing the locking part 41 from rotating excessively or causing unnecessary shaking, thereby stably controlling the switching of the locking part 41 between the locked and unlocked positions and ensuring the normal working state of the entire pet door clutch device.

[0066] The direction of the elastic restoring force of the reset member 42 is perpendicular to the parallel direction of the first connecting member 20 and the second connecting member 30, that is, parallel to the first direction. Thus, under normal circumstances, for the locking part 41 to lock with the mating part 31 and achieve synchronous movement, the elastic restoring force of the reset member 42 along the first direction steadily "blocks" the locking part 41 from the side, helping it to accurately position and maintain the locked state; when unlocking is required, the locking part 41 rotates against a certain external force, and the elastic restoring force along the first direction still plays a role in limiting its lateral displacement during this process, ensuring that the unlocking action is completed smoothly and accurately.

[0067] Furthermore, referring to Figure 5 The locking part 41 is arranged in a parallel direction. One end of the locking part 41 is rotatably connected to the first connector 20, and the other end is locked with the mating part 31. The reset part 42 includes a first elastic segment 421 connected to the locking part 41. The first elastic segment 421 is provided on one side of the locking part 41 in the first direction.

[0068] In this embodiment, under normal conditions, the first elastic segment 421 uses its elastic restoring force to keep the locking part 41 in the locked position, maintaining the locked state with the mating part 31. When the pet door clutch device 100 malfunctions, external force overcomes the elastic force of the first elastic segment 421, causing the locking part 41 to rotate to the unlocked position. When the external force disappears, the first elastic segment 421 can again use its own elastic restoring force to cause the locking part 41 to rotate back to the locked position, realizing the reset function and ensuring that the entire pet door clutch device 100 can repeatedly work normally.

[0069] Furthermore, referring to Figure 6 and Figure 7The reset member 42 also includes a second elastic segment 422 connected to the locking part 41. The second elastic segment 422 and the first elastic segment 421 are respectively disposed on both sides of the locking part 41 in the first direction. When the locking part 41 rotates, one of the first elastic segment 421 and the second elastic segment 422 is stretched and the other is compressed to switch the unlocked position and the locked position of the locking part 41.

[0070] In this embodiment, when the locking part 41 rotates under the action of an external force, the first elastic segment 421 and the second elastic segment 422 exhibit different deformation states, one being stretched and the other compressed. For example, when the locking part 41 rotates from the locked position to the unlocked position, assuming the first elastic segment 421 is stretched, it will generate a pulling force that hinders the locking part 41 from continuing to rotate. At the same time, the second elastic segment 422 is in a compressed state, generating an elastic force that also hinders the rotation of the locking part 41. The two work together to ensure that the locking part 41 is subject to reasonable resistance control during rotation, preventing the door 60 from falling rapidly and injuring the pet if it rotates too fast or out of control. Conversely, when the locking part 41 rotates from the unlocked position back to the locked position, the stretching and compression states of the two are reversed. In the same way, this mutual cooperation provides the locking part 41 with precise reset power, ensuring that the locking part 41 can accurately and stably return to the corresponding position, and achieving effective control of the pet door's open / closed state.

[0071] In some embodiments, refer to Figure 8 and Figure 9 The locking part 41 is arranged in a parallel direction. One end of the locking part 41 is rotatably connected to the first connecting member 20, and the other end is locked with the mating part 31. The resetting member 42 includes two first support arms 423 disposed on both sides of the locking part 41 in a first direction. The two first support arms 423 are arranged at an angle. One end of each of the two first support arms 423 is connected to the locking part 41, and the other end of each of the two first support arms 423 is slidably connected to the first connecting member 20 in the first direction.

[0072] Referring to the fifth and sixth embodiments, one end of the locking part 41 is rotatably connected to the first connecting member 20. This rotatable connection allows the locking part 41 to flexibly change its position, enabling it to rotate around the connection point, thereby achieving locking or disengagement with the mating part 31. The two first support arms 423 are set at an angle, allowing force to be applied to the locking part 41 from different angles. When the locking part 41 is subjected to external force and needs to rotate, the angle between the two first support arms 423 will change accordingly, and the direction and magnitude of their component forces will also change accordingly. Together, they will adjust the rotation amplitude and speed of the locking part 41, preventing the locking part 41 from rotating too fast or too violently to disengage or lock, achieving precise control of the movement of the locking part 41, ensuring that the locking part 41 accurately switches positions, and thus ensuring the reliable operation of the pet door clutch device 100.

[0073] Reference Figure 8 In one embodiment, the first support arm 423 is made of an elastic material, including but not limited to metal and elastic plastic. The first support arm 423 has a certain elasticity and can generate corresponding elastic deformation according to the rotation angle of the locking part 41 during the rotation of the locking part 41. The rotation amplitude and speed of the locking part 41 can be adjusted by the change of elastic force, so as to achieve precise control of the switching of the locking part 41 between the locked position and the unlocked position.

[0074] Reference Figure 9 In one embodiment, the first support arm 423 is not made of an elastic material, but only has elastic deformation capability. Meanwhile, a stop 50 is provided on one side of the locking part 41 in the first direction to limit excessive rotation of the locking part 41. Further, the top surface of the stop 50 is arc-shaped. When the locking part 41 rotates to a certain extent, the stop 50 will contact the locking part 41, at which point the arc surface can act as a buffer. Compared to a planar stop structure, the arc surface can distribute the contact stress more evenly at the moment of contact, avoiding stress concentration and reducing damage to the component caused by the impact force generated by the collision. It can also more smoothly limit the excessive rotation of the locking part 41, accurately determining the locking and unlocking positions of the locking part 41.

[0075] In some embodiments, refer to Figure 4 , Figure 10 , Figure 11 and Figure 12 The direction of the elastic restoring force of the reset member 42 is set at an angle to the first direction. The locking part 41 can move relative to the mating part 31 along the parallel direction of the first connector 20 and the second connector 30 to switch the locking position and the unlocking position.

[0076] Referring to the first, seventh to ninth embodiments, the direction of the elastic restoring force of the reset member 42 is set at an angle to the first direction. This angle setting allows the components of the force of the reset member 42 in different directions to participate in the control of the locking part 41. For example, when the locking part 41 moves along the parallel direction to perform locking or unlocking operations, the component of the elastic restoring force along the parallel direction can directly affect the ease of movement of the locking part 41 and its final position, while its component perpendicular to the parallel direction can play a role in assisting stability and preventing unnecessary deviation of the locking part 41, making the movement and position control of the locking part 41 more precise and reliable.

[0077] Furthermore, referring to Figure 4 , Figure 10 The locking part 41 and the reset member 42 are arranged in a parallel direction. The direction of the elastic restoring force of the reset member 42 extends in the parallel direction. The end of the reset member 42 away from the locking part 41 is fixed to the first connecting member 20.

[0078] In this embodiment, the elastic restoring force of the reset member 42 extends in the parallel direction. Thus, the reset member 42 provides precise lateral constraint for the movement of the locking part 41. When the locking part 41 moves in the parallel direction to perform locking and unlocking operations, this vertical force effectively prevents lateral deviation or wobbling of the locking part 41, ensuring it moves along a precise predetermined track. This allows the locking part 41 to accurately reach the locked or unlocked position, thereby achieving high-precision control of the pet door's engagement / disengagement state.

[0079] Furthermore, referring to Figure 10 In some embodiments, the locking portion 41 is elongated. A stop 50 is provided on one side of the locking portion 41 in the first direction to limit excessive rotation of the locking portion 41. Furthermore, the top surface of the stop 50 is arc-shaped. When the locking portion 41 rotates to a certain extent, the stop 50 will contact the locking portion 41, at which point the arc surface acts as a buffer. Compared to a planar stop structure, the arc surface allows for a more even distribution of contact stress at the moment of contact, avoiding stress concentration and reducing damage to the component caused by the impact force generated by the collision. It also more smoothly limits the excessive rotation of the locking portion 41, accurately determining the locking and unlocking positions of the locking portion 41.

[0080] In some embodiments, reference is made to Figure 11 The locking structure also includes two third support arms 45 located on both sides of the locking part 41 in the first direction. The two third support arms 45 are arranged at an angle. One end of each of the two third support arms 45 can be slidably connected to the first connecting member, and the other end of each of the two third support arms 45 is connected to the locking part 41. The reset member 42 is located between the two third support arms 45, with one end fixed to the first connecting member and the other end connected to the locking part 41.

[0081] In this embodiment, the third support arm 45 provides stable support to the locking part 41 from both sides, ensuring that it can accurately lock or disengage with the mating part, thereby reliably controlling the opening and closing state of the pet door. The reset member 42 provides the locking part 41 with the ability to elastically reset, enabling the locking part 41 to switch between the locked and unlocked positions.

[0082] In one embodiment, reference is made to Figure 12 The first connector 20 is provided with a mounting groove 22 facing the second connector 30, and the locking structure 40 is placed in the mounting groove 22; the reset member 42 includes two elastic support arms 425 provided on both sides of the locking part 41 in the first direction, and the two elastic support arms 425 are set at an included angle; one end of each elastic support arm 425 can be slidably placed in the mounting groove 22, and the other end of each elastic support arm 425 is connected to the locking part 41.

[0083] In this embodiment, the mounting groove 22 provides a specific mounting space for the locking structure 40. The arrangement and connection of the elastic support arms 425 allow the elastic support arms 425 to apply force to the locking part 41 from both sides, and to adapt to changes in the position of the locking part 41 by sliding within the mounting groove 22. The two elastic support arms 425 are arranged at an angle, allowing them to apply force to the locking part 41 from different angles. When the locking part 41 is subjected to external force and needs to rotate, the angle between the two elastic support arms 425 changes accordingly, and the direction and magnitude of their component forces also change. These forces work together to adjust the rotation amplitude and speed of the locking part 41, preventing it from rotating too quickly or too violently and disengaging or locking, thus achieving precise control of the movement of the locking part 41 and ensuring accurate position switching, thereby guaranteeing the reliable operation of the pet door clutch device 100.

[0084] Furthermore, please refer to the following: Figure 12 The side wall of the mounting groove 22 is provided with a first guide groove 51 for the elastic support arm 425 to slide and a second guide groove 52 for the locking member to move. The first guide groove 51 and the second guide groove 52 ensure that the elastic support arm 425 and the locking part 41 can only slide in a set direction, avoiding unnecessary offset, shaking or deviation from the predetermined movement trajectory of the elastic support arm 425 and the locking member, thereby ensuring the regularity of the movement of the entire clutch device.

[0085] In one embodiment, reference is made to Figure 13 The locking structure 40 includes an adapter arm 43, and the reset member 42 includes a spring piece 426 arranged at an angle to the first direction; the spring piece 426 is connected to the first connector 20 and the adapter arm 43 on both sides in the parallel direction; the locking structure 40 includes an adapter arm 43, one end of which forms a locking part 41, and the other end of which is connected to the spring piece 426.

[0086] In this embodiment, one end of the adapter arm 43 forms a locking part 41, and the other end is connected to a spring piece 426. The adapter arm 43 plays a role in force transmission, transferring the elastic restoring force of the spring piece 426 to the locking part 41, and also transferring the external force on the locking part 41 to the spring piece 426. In addition, the adapter arm 43 can also realize the conversion of the motion mode. For example, when the locking part 41 needs to move in a parallel direction to switch between the locked and unlocked positions, the adapter arm 43 can reasonably convert the force and motion direction generated by the elastic restoring force of the spring piece 426, ensuring that the locking part 41 can move in the expected manner and direction, and achieving precise position control.

[0087] In one embodiment, reference is made to Figure 14The first connector 20 is provided with a slide groove 21 extending in the first direction; the locking structure 40 also includes two second support arms 424 provided on both sides of the locking part 41 in the first direction; one end of each of the two second support arms 424 is connected to the locking part 41, and the other end of each of the two second support arms 424 can be slidably placed in the slide groove 21.

[0088] The reset member 42 is placed in the slide groove 21, and the reset member 42 is connected to a second support arm 424 in the first direction. The direction of the elastic restoring force of the reset member 42 is set at an angle to the parallel direction of the first connector 20 and the second connector 30. The locking part 41 can move relative to the mating part 31 through the reset member 42 to switch the locking position and the unlocking position.

[0089] In this embodiment, the slide 21 defines the movement direction of the second support arm 424 and the reset member 42, preventing them from deviating from the predetermined trajectory, thereby making the movement of the locking structure 40 more orderly and stable. The second support arm 424 supports the locking part 41 from both sides in the first direction, enhancing the stability of the locking part 41 during movement and in different positions (locked or unlocked). At the same time, it defines the movement trajectory of the locking member, ensuring that it can accurately lock or disengage with the mating part 31, thereby reliably controlling the opening and closing state of the pet door.

[0090] In one embodiment, reference is made to Figure 15 The first connector 20 has a receiving groove 23 on its side wall facing the second connector 30. The locking structure 40 includes an elastic piece arranged corresponding to the receiving groove 23. One end of the elastic piece is connected to the first connector 20, and the other end of the elastic piece forms a locking part 41. The locking part 41 rotates relative to the mating part 31 toward the receiving groove 23 to switch between the locking position and the unlocking position.

[0091] In this embodiment, the receiving groove 23 provides space for the elastic sheet to deform. During the position switching of the locking part 41 (from the locked position to the unlocked position or vice versa), the elastic sheet undergoes corresponding elastic deformation. For example, when the locking part 41 is subjected to an external force and rotates towards the receiving groove 23 to unlock, the elastic sheet is stretched or twisted, storing elastic potential energy; and when the external force disappears, the elastic sheet, by its own elastic restoring force, causes the locking part 41 to rotate in the opposite direction back to the locked position, realizing the reset function, thereby ensuring that the pet door clutch device 100 can reliably switch between different working states.

[0092] In one embodiment, reference is made to Figure 16The locking structure 40 includes a rubber strip 44, which includes a fixed section 441 and a locking part 41 connected to each other. The first connector 20 has an assembly groove facing the locking part 41, and the fixed section 441 is inserted into the assembly groove. The locking part 41 is deformable relative to the mating part 31 to have a locking position that engages with the mating part 31 and an unlocking position that disengages from the mating part 31.

[0093] In this embodiment, the main function of the fixing section 441 inserted into the assembly groove of the first connector 20 is to securely install the rubber strip 44 on the first connector 20, providing a stable support base for the entire locking structure 40, ensuring that the locking part 41 can accurately perform its function during subsequent use, and ensuring that the rubber strip 44 will not easily shift or loosen, thus ensuring the reliability of the connection between the locking structure 40 and the first connector 20.

[0094] The locking part 41 is deformable relative to the mating part 31, a feature that allows it to engage with the mating part 31 in different working states. In the locked position, the locking part 41 and the mating part 31 are tightly locked, allowing the first connecting member 20 and the second connecting member 30 to move synchronously, thus realizing the normal opening and closing of the pet door. When unlocking is required, the locking part 41 can deform, disengaging from the locking relationship with the mating part 31 and entering the unlocked position, allowing the second connecting member 30 to move flexibly relative to the first connecting member 20, meeting the usage needs of the pet door in special circumstances (such as allowing pets to freely enter and exit in case of malfunction, manual adjustment, etc.).

[0095] In some embodiments, friction plates 53 are provided on opposite sides of the first connector 20 and the second connector 30. The first connector 20 and the second connector 30 achieve synchronous movement through the friction between the friction plates 53. When an external force greater than the friction between the friction plates 53 is applied, the first connector 20 and the second connector 30 separate.

[0096] This utility model also proposes a cat litter box 200, which includes a shell, a door 60, a drive component 61, and a pet door clutch device 100. The specific structure of the pet door clutch device 100 is as described in the above embodiments. Since this cat litter box 200 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0097] The door body 60, the drive unit 61, and the pet door clutch device 100 are mounted on the housing; one of the first connecting member 20 and the second connecting member 30 of the pet door clutch device 100 is connected to the drive unit 61, and the other is connected to the door body 60.

[0098] In the locked position, the first connector 20 and the second connector 30 of the pet door clutch device 100 move synchronously under the action of the drive member 61; in the unlocked position, the first connector 20 of the pet door clutch device 100 can slide relative to the second connector 30 of the pet door clutch device 100.
