Description

Technical Field

[0001] This invention relates to pet products, specifically pet activity restraint devices. Background Technology

[0002] With the acceleration of urbanization, the need for spatial management of pets' outdoor activities is becoming increasingly prominent. To better supervise pets' outdoor activity range and prevent safety hazards caused by pets straying outside designated areas, several solutions for pet range monitoring have emerged. For example, the existing pet collar system and control method (technical announcement number CN108308059B) employs base station and satellite differential positioning technology. By correcting positioning errors, it achieves high-precision range detection, triggering an audible alarm when a pet approaches the activity boundary. Its core advantage lies in improving the accuracy of traditional GNSS positioning from meter-level to sub-meter-level through differential positioning technology, significantly reducing the probability of false alarms. However, it still has shortcomings. This solution relies solely on audible alarms and heavily depends on manual supervision, which is challenging. Therefore, a solution that improves the effectiveness of supervision and makes the monitoring method more efficient is needed. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a pet activity range restraint device that can improve the safety of pet supervision, reduce human intervention, and improve the effectiveness of continuous supervision.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a pet activity range restraint device, comprising a wearable unit that can be worn on a pet, wherein the wearable unit has a built-in positioning component and a restraint warning component; the positioning component is used to cooperate with a user terminal to obtain distance information, and when the pet leaves the preset activity range, the restraint warning component performs a clamping action to create an uncomfortable stimulus to the pet, thereby warning the pet.

[0005] As a further improvement of the present invention, the restraint warning component includes a carrier box, a restraint member passing through the carrier box, a locking member for limiting the reverse loosening of the restraint member, and a contact member rotatably mounted on the carrier box; the restraint member is provided with multiple engaging portions that cooperate with the locking member, and the contact member is located inside the restraint member; the carrier box also provides a drive component and a control module, and the positioning component is integrated into the control module; when the pet leaves the preset activity range, the control module controls the drive component to drive the contact member to rotate, so that the contact member clamps the pet.

[0006] As a further improvement of the present invention, the driving assembly includes a power component, a transmission component, and an actuator. The actuator is connected to the transmission component in a transmission manner. The power component drives the transmission component to move, thereby causing the actuator to move. When the actuator moves, it pushes the contact component to rotate, causing the contact component to clamp the pet. When the actuator moves in the opposite direction, the contact component releases.

[0007] As a further improvement of the present invention, the power component is a motor, the transmission component is a lead screw, and the actuating component is a slider; the slider is threadedly connected to the lead screw, the motor drives the lead screw to rotate to drive the slider to slide, and the slider pushes the contact component to rotate to achieve clamping; an elastic component is sleeved on the lead screw, and when the slider slides in the reverse direction, the elastic component pushes the contact component to reset and release the pet.

[0008] As a further improvement of the present invention, the actuator is also used to drive the locking member to release the restriction on the restraint member: the actuator moves toward the locking member and pushes the locking member, so that the locking member separates from the engaging part, thereby unlocking the restraint member.

[0009] As a further improvement of the present invention, the locking member has a V-shaped structure, and its corner is mounted on the carrier box through a hinge shaft. The locking member maintains the engagement tendency with the engaging part through an elastic reset member. The groove of the V-shaped locking member allows the actuator to enter and push the locking member.

[0010] As a further improvement of the present invention, a manual operation component is also included. The manual operation component includes a password component and an unlockable operating component. After the password component is entered correctly, it unlocks the operating component. One end of the operating component abuts against the tail of the power component. By pressing down the operating component, the power component can swing, thereby driving the actuator to pry open the locking component, so that the locking component is separated from the engaging part.

[0011] As a further improvement of the present invention, the carrier box is also provided with an elastic component, which provides elastic force for the power component to reset; when the operating component releases the power component, the power component is reset through the elastic component.

[0012] As a further improvement of the present invention, the power component is mounted in the carrier box by a bracket, and the power component is oscillatingly connected to the bracket, the bracket being used to support the power component and allow it to oscillate.

[0013] As a further improvement of the present invention, the password assembly includes a fixed plate fixed in a carrier box, an unlocking plate slidably disposed on the fixed plate, and a plurality of buttons passing through the fixed plate. The operating member is located on the side of the unlocking plate, and the unlocking plate is kept moving toward the operating member by a spring. The fixed plate is also provided with a locking member that can rotate toward or away from the operating member. The locking member is kept moving toward the operating member by a torsion spring. The operating member is provided with a locking groove for engaging the locking member. When the locking member is embedded in the locking groove, the operating member is locked. The unlocking plate is provided with an unlocking protrusion, and the locking member is provided with a engaging protrusion. When the button is pressed to input the correct password, the unlocking plate abuts against the operating member by elastic force, and the unlocking protrusion pushes open the engaging protrusion to drive the locking member to rotate away from the operating member, thereby unlocking the operating member. The operating member is also provided with a guide protrusion. When the operating member is pressed, the guide protrusion pushes the unlocking plate away from the operating member and releases the restriction on the button, allowing the button to change the password. The beneficial effects of this invention are as follows: Real-time monitoring of pet location is achieved by cooperating with the positioning component and the user terminal. When the pet leaves the preset activity range, the restraint warning component creates an uncomfortable stimulus to the pet through a clamping action. Compared with the existing technology that only relies on sound alarms, this invention can actively warn the pet without continuous manual supervision, effectively improving the reliability of restraining the pet's activity range, reducing the safety risks of the pet leaving the supervision range, and enhancing the supervision effect.

[0015] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.

[0016] Reference Figure 1-8 As shown, A pet activity range restraint device includes a wearable unit 1 that can be worn on a pet. The wearable unit 1 has a built-in positioning component and a restraint warning component 12. The positioning component is used to cooperate with a user terminal to obtain distance information. When the pet leaves the preset activity range, the restraint warning component 12 performs a clamping action to create an uncomfortable stimulus to the pet and realize the warning to the pet.

[0017] Structurally, the wearing unit 1 can take the form of a collar, chest strap, etc., and is fixed to the pet's neck or torso with buckles or Velcro. The positioning component can use a GNSS module (such as GPS, Beidou) and integrate a wireless communication module (such as Bluetooth, Wi-Fi) to establish a communication connection with the user terminal (such as a mobile APP). The user terminal can preset the activity range (such as by defining it through an electronic fence function). The restraint warning component 12 is electrically connected to the positioning component via a wire and receives signals from the positioning component.

[0018] When the pet moves within the preset range, the positioning component transmits its location information to the user terminal in real time. The user terminal calculates the distance between the pet and the range boundary and feeds it back to the positioning component, while the restraint warning component 12 remains in its initial state. When the pet approaches or leaves the preset range, the positioning component receives a trigger signal from the user terminal and activates the restraint warning component 12: the actuator in the restraint warning component 12 (such as a movable contact piece) clamps towards the pet's body, creating a slight pressure sensation (non-harmful discomfort) on the pet's skin. The pet, feeling uncomfortable, will stop its attempt to leave the range or return to the area. At this point, the positioning component receives a reset signal from the user terminal, and the restraint warning component 12 releases. This structure achieves warning through active physical stimulation, solving the problem that audible alarms are easily ignored by pets and rely on manual intervention, thus improving the timeliness and effectiveness of restraint.

[0019] In an optional specific solution, the restraint warning component 12 includes a carrier box 121, a restraint member 122 passing through the carrier box 121, a locking member 123 for limiting the reverse loosening of the restraint member 122, and a contact member 124 rotatably mounted on the carrier box 121; the restraint member 122 is provided with multiple engaging parts 125 that cooperate with the locking member 123, and the contact member 124 is located inside the restraint member 122; the carrier box 121 is also provided with a drive component 126 and a control module, and the positioning component is integrated into the control module; when the pet leaves the preset activity range, the control module controls the drive component 126 to drive the contact member 124 to rotate, so that the contact member 124 clamps the pet.

[0020] The carrier box 121 can be a rigid plastic box, fixed to the wearing unit 1; the restraint 122 can be a flexible leather strap, with both ends passing through the carrier box 121 to form a ring, adapting to pets of different sizes; the engaging part 125 consists of evenly distributed serrated protrusions on the surface of the restraint 122; the locking part 123 is a claw, installed inside the carrier box 121 at a position corresponding to the engaging part 125; the contact part 124 is an arc-shaped plastic or metal sheet, hinged to the carrier box 121 by a pin. The control module is an MCU integrated on a PCB board, the positioning components (GNSS module, wireless communication module) are soldered to the PCB board, and the drive component 126 is electrically connected to the control module via wires.

[0021] When the pet wears the device, the tightness is adjusted by pulling the restraint 122. The locking part 123 cooperates with the engaging part 125 to prevent the restraint 122 from loosening, ensuring a secure fit. When the pet moves out of the preset range, the control module receives a signal from the positioning component and outputs an electrical signal to the drive component 126. The drive component 126 drives the contact 124 to rotate inward around the pin axis. The inner side of the contact 124 contacts the pet's skin and gradually clamps it (the clamping force can be preset by the control module to avoid excessive pressure). Because the contact 124 is located inside the restraint 122, the restraining effect of the restraint 122 enhances the clamping effect of the contact 124, causing the pet to experience clear discomfort and thus stop the pet from moving out.

[0022] Specifically, the drive assembly 126 includes a power component 1261, a transmission component 1262, and an actuator 1263. The actuator 1263 is connected to the transmission component 1262. The power component 1261 drives the transmission component 1262 to move, thereby causing the actuator 1263 to move. When the actuator 1263 moves, it pushes the contact component 124 to rotate, causing the contact component 124 to clamp the pet. When the actuator 1263 moves in the opposite direction, the contact component 124 is released.

[0023] The power component 1261 can be a miniature DC motor, fixed to the inner wall of the carrier box 121; the transmission component 1262 can be a gear set (the driving gear is keyed to the motor output shaft, and the driven gear is driven by the actuator 1263); the actuator 1263 is a metal push rod, one end of which is eccentrically hinged to the driven gear, and the other end is in contact with the outer side of the contact component 124. The power component 1261 is electrically connected to the control module via wires and receives its control signals.

[0024] When the pet moves out of the preset range, the control module controls the power component 1261 to rotate forward. The power component 1261 drives the drive gear to rotate, and the driven gear rotates accordingly. Through the eccentric structure, the drive component 1263 is pushed to move in a straight line towards the contact component 124. The drive component 1263 pushes the contact component 124 to rotate around the pin, thus clamping it. At this time, the pet stops moving due to discomfort, and the control module controls the power component 1261 to rotate in reverse. The transmission component 1262 drives the drive component 1263 to move in the opposite direction. The contact component 124 rotates in the opposite direction under its own weight or the action of a return spring (which can be added between the contact component 124 and the carrier box 121) to release. This drive assembly 126 achieves precise rotation control of the contact component 124 through the cooperation of the power component 1261, the transmission component 1262, and the drive component 1263. The switching between forward and reverse displacement can quickly switch between clamping and releasing, improving the timeliness of the device response. At the same time, the mechanical transmission method of the transmission component 1262 has high stability and is suitable for the vibration environment when the pet is active.

[0025] Unlike the aforementioned drive assembly 126 structure, in this preferred embodiment, the power component 1261 is a motor, the transmission component 1262 is a lead screw, and the actuator 1263 is a slider; the slider is threadedly connected to the lead screw, and the motor drives the lead screw to rotate to drive the slider to slide. The slider pushes the contact component 124 to rotate to achieve clamping; an elastic component 1264 is sleeved on the lead screw. When the slider slides in the opposite direction, the elastic component 1264 pushes the contact component 124 to reset and release the pet.

[0026] One end of the lead screw is connected to the motor output shaft via a coupling or welded; the inner side of the slider has an internal thread that mates with the lead screw and also contacts the outer side of the contact element 124; the elastic element 1264 is a compression spring, sleeved on the lead screw, with one end abutting against the contact element 124 and the other end abutting against the end of the motor.

[0027] When the pet leaves the area, the control module controls the motor to rotate forward. The lead screw rotates, causing the slider to slide along the lead screw towards the contact 124. The slider pushes the contact 124 to rotate around the pin, clamping the pet. At the same time, the slider compresses the elastic element 1264. When the pet returns to the area, the motor reverses, the lead screw drives the slider to slide in the opposite direction, and the elastic element 1264 releases its elastic force, pushing the contact 124 to reset. The contact 124 then rotates in the opposite direction to release the pet. The threaded connection between the lead screw and the slider has self-locking properties, ensuring that the slider remains stably in the clamped state and preventing loosening due to pet movement. The elastic element 1264 makes the reset of the contact 124 smoother.

[0028] In order to further realize the unlocking of the restraint member 122 in a compact structure, preferably, the actuator 1263 is also used to drive the locking member 123 to release the restriction on the restraint member 122: the actuator 1263 moves toward the locking member 123 and pushes the locking member 123, so that the locking member 123 separates from the engaging part 125, thereby unlocking the restraint member 122.

[0029] The locking element 123 is a metal or plastic sheet, with one end hinged to the carrier box 121 and the other end engaged with the engaging part 125 (serrated protrusion). Its middle position corresponds to the actuator 1263 (slider). The actuator 1263 has a protrusion on the side facing the locking element 123. The positions of the actuator 1263, locking element 123, and restraint element 122 correspond to ensure that the actuator 1263 can contact the locking element 123 when it moves.

[0030] When it is necessary to adjust the tightness of the restraint 122 or remove the device, the control module can receive an unlocking signal from the user terminal (such as a command sent by the user via APP), and control the power component 1261 to drive the actuator 1263 to move towards the locking component 123. The actuator 1263 pushes the locking component 123 to rotate around the hinge point, causing the locking component 123 to separate from the engaging part 125. At this time, the restraint 122 can be pulled to adjust its length. After the adjustment is completed, the actuator 1263 moves in the opposite direction, and the locking component 123 resets under its own weight or the action of the return spring, re-engaging with the engaging part 125. This structure allows the actuator 1263 to function as both the clamping contact 124 and the unlocking restraint 122, simplifying the device structure and eliminating the need for an additional unlocking drive component. At the same time, unlocking is achieved through the displacement of the actuator 1263, making operation convenient and improving user convenience.

[0031] To facilitate engagement with the actuator 1263, the locking member 123 has a V-shaped structure, with its corners mounted on the carrier box 121 via a hinge shaft. The locking member 123 maintains its engagement tendency with the engaging part 125 via an elastic reset member 1231. The groove of the V-shaped locking member 123 allows the actuator 1263 to enter and push the locking member 123.

[0032] The locking element 123 is V-shaped, with its corner hinged to the inner wall of the carrier box 121 via a pin. One end is the engaging end (which engages with the engaging part 125), and the other end is the force-bearing end, forming a groove between the two ends. The elastic reset element 1231 is a torsion spring 215, sleeved on the hinge shaft. One end abuts against the locking element 123, and the other end abuts against the inner wall of the carrier box 121, so that the engaging end always tends to move closer to the engaging part 125. The end of the actuator 1263 (slider) can extend into the groove.

[0033] When the restraint member 122 is adjusted, the actuator 1263 moves towards the groove and extends into the groove, pushing the force-bearing end of the locking member 123, causing the locking member 123 to rotate around the hinge axis, and the engaging end separates from the engaging part 125 (the elastic reset member 1231 is twisted and stores force); after the actuator 1263 is released, the elastic reset member 1231 releases its elastic force, causing the locking member 123 to rotate in the opposite direction, and the engaging end re-engages with the engaging part 125. The V-shaped locking member 123 receives the pushing force of the actuator 1263 through the groove, making the engagement more convenient and stable.

[0034] In addition to the electric unlocking method, a manual unlocking method can also be added. Specifically, it includes a manual operation component 2, which includes a password component 21 and an unlockable operating component 22. After the password component 21 is entered correctly, it unlocks the operating component 22. One end of the operating component abuts against the tail of the power component 1261. By pressing down the operating component 22, the power component 1261 can swing, which in turn drives the actuator 1263 to pry open the locking component 123, so that the locking component 123 separates from the engaging part 125.

[0035] The password component 21 is a mechanical combination lock or a password key 213, which is installed on the surface of the carrier box 121; the operating component 22 is slidably installed on the side or end face of the carrier box 121, with one end extending out of the carrier box 121 for pressing, and the other end slidably connected to the inside of the carrier box 121 and abutting the tail of the power component 1261 (motor); the power component 1261 and the carrier box 121 are rotatably connected, allowing a certain angle of swing.

[0036] The user enters the correct password through the password component 21, which unlocks the operating component 22. The user then presses down on the operating component 22, causing it to push the power component 1261 to swing. The power component 1261 drives the transmission component 1262 (such as a lead screw) to swing synchronously. The actuator 1263 (slider) swings with the transmission component 1262 and pries open the locking component 123, causing the locking component 123 to separate from the engaging part 125, thus manually unlocking the restraint component 122. This manual operating component 2 serves as a backup for electronic control, enhancing the device's emergency response capability and preventing pets from being continuously restrained when electronic control fails, thereby improving the device's safety and reliability.

[0037] Preferably, the carrier box 121 is further provided with a spring member 23, which provides the spring force for the power member 1261 to reset; when the operating member 22 releases the power member 1261, the power member 1261 is reset through the spring member 23. The spring member 23 can be an elastic sheet, with one end fixed inside the carrier box 121 and the other end abutting against the power member 1261.

[0038] When the user presses down the operating component 22 to make the power component 1261 swing, the power component 1261 presses down the elastic component 23, and the elastic component 23 stores elastic potential energy; when the user releases the operating component 22, the elastic component 23 releases potential energy, pushing the power component 1261 to swing back to the initial position. The power component 1261 drives the transmission component 1262 and the actuator 1263 to reset synchronously, and the locking component 123 re-engages with the engaging part 125 under the action of the elastic reset component 1231.

[0039] Preferably, the power component 1261 is mounted in the carrier box 121 via a bracket 12611. The power component 1261 is oscillatingly connected to the bracket 12611, which supports the power component 1261 and allows it to oscillate.

[0040] The bracket 12611 is U-shaped and is fixed to the carrier box 121 by screws or integrally formed. The power component 1261 is hinged to the bracket 12611, allowing the power component 1261 to swing around the rotation axis in a vertical plane. This bracket 12611 structure can provide a certain support height, making the swing of the power component 1261 smoother.

[0041] In the specific scheme, the cryptographic component 21 can be implemented in the following manner, as shown in the reference. Figure 2 , 3 As shown in Figures 6, 7, and 8: The password component 21 includes a fixed plate 211 fixed in the carrier box 121, an unlocking plate 212 slidably disposed on the fixed plate 211, and several buttons 213 passing through the locking plate. The operating member 22 is located on the side of the unlocking plate 212, and the unlocking plate 212 is kept moving toward the operating member 22 by a spring. The fixed plate 211 is also provided with a locking member 214 that can rotate toward or away from the operating member 22. The locking member 214 is kept moving toward the operating member 22 by a torsion spring 215. The operating member 22 is provided with a locking groove 216 for cooperating with the locking member 214. When the locking member 214 is embedded in the locking groove 216... When the button 213 is pressed to input the correct password, the unlocking plate 212 is provided with an unlocking protrusion 217, and the locking member 214 is provided with a cooperating protrusion 218. When the button 213 is pressed to input the correct password, the unlocking plate 212 is elastically pressed against the operating member 22, and the unlocking protrusion 217 pushes away the cooperating protrusion 218 to drive the locking member 214 to rotate away from the operating member 22, thereby unlocking the operating member 22. The operating member 22 is also provided with a guide protrusion 219. When the operating member 22 is pressed, the guide protrusion 219 pushes the unlocking plate 212 away from the operating member 22 and releases the restriction on the button 213, allowing the button 213 to change the password.

[0042] The fixed plate 211 is a rigid plastic plate, fixed to the inner wall of the carrier box 121; the unlocking plate 212 is slidably connected to the fixed plate 211 through a slide rail or guide component; the lower end of the button 213 and the unlocking plate 212 form a password through a cam and groove; one end of the spring is connected to the unlocking plate 212, and the other end abuts against the inner wall of the carrier box 121; the locking member 214 is hinged to the fixed plate 211 through a pin, and the torsion spring 215 is sleeved on the pin, with one end abutting against the locking member 214 and the other end abutting against the fixed plate 211; the guide protrusion 219 is a wedge-shaped block on the side of the operating member 22.

[0043] In the initial state, the locking member 214 is embedded in the locking groove 216 of the operating member 22 under the action of the torsion spring 215, and the operating member 22 is locked. When the correct password is entered, the protrusion on the unlocking plate 212 will match the groove on the button 213. The unlocking plate 212 moves under the action of the spring force, and the protrusion will insert into the groove to restrict the rotation of the button 213. At the same time, the unlocking protrusion 217 on the unlocking plate 212 contacts the cooperating protrusion 218 of the locking member 214 and pushes the locking member 214 away. The locking member 214 rotates around the pin and disengages from the locking groove 216, and the operating member 22 is unlocked. When the user presses the operating member 22, the wedge-shaped surface of the guiding protrusion 219 pushes the unlocking plate 212 away from the operating member 22 along the slide rail. The unlocking plate 212 releases the restriction on the button 213. The user can press the button 213 again to set a new password. After setting, the user releases the operating member 22, and the unlocking plate 212 resets under the action of the spring, re-restricting the button 213. The password component 21 achieves password verification and unlocking through a mechanical structure, which is simple to operate and highly secure. It supports password changing, enhancing user flexibility and preventing security risks caused by password leakage. Furthermore, the operating component 22 can not only be used to swing the power component 1261 to unlock, but also to change the password of the button 213. The password structure of the button 213 can adopt the password structure of the button 213 padlock with prior art announcement number CN120083417B.
