Description

Technical Field

[0001] The present invention relates to pet products, in particular to a device for restricting the range of pet activity. Background Art

[0002] With the acceleration of urbanization, the need for space management for pets' outdoor activities has become increasingly prominent. To better regulate pets' outdoor activities and prevent safety hazards caused by pets' activities escaping from the regulatory scope, some pet regulation schemes have begun to emerge.

[0003] For example, the pet collar system and control method, published in prior art publication number CN108308059B, utilizes base station and satellite differential positioning technology to achieve high-precision range detection by correcting positioning errors. This system triggers an audible alarm when a pet approaches its activity boundary. Its core advantage lies in improving traditional GNSS positioning accuracy from meter-level to sub-meter-level through differential positioning technology, significantly reducing the probability of false alarms. However, this solution still has drawbacks. This solution relies solely on audible alarms and relies heavily on manual supervision, which is difficult. Therefore, a solution is needed to improve and make supervision more effective. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a pet activity range restraint device that can improve the safety of pet supervision, reduce manual participation, and improve the effect of continuous supervision.

[0007] As a further improvement of the present invention, the driving assembly includes a power member, a transmission member and an actuator. The actuator is connected to the transmission member through transmission, and the transmission member is driven to move by the power member to drive the actuator to move; when the actuator is displaced, it pushes the contact member to rotate, so that the contact member clamps the pet; when the actuator is displaced in the opposite direction, the contact member is released.

[0008] As a further improvement of the present invention, the power part is a motor, the transmission part is a screw rod, and the actuator is a slider; the slider is threadedly connected to the screw rod, the motor drives the screw rod to rotate to drive the slider to slide, and the slider pushes the contact part to rotate to achieve clamping; an elastic part is sleeved on the screw rod, and when the slider slides in the opposite direction, the elastic part pushes the contact part to reset and release the pet.

[0009] As a further improvement of the present invention, the actuator is also used to drive the locking member to release the restriction on the restraining member: the actuator moves toward the locking member and pushes the locking member to separate the locking member from the engaging part, thereby unlocking the restraining member.

[0010] As a further improvement of the present invention, the locking member is a V-shaped structure, the corner of which is mounted on the carrier box through a hinge shaft, and the locking member maintains a matching tendency with the engaging portion through an elastic reset member; the groove of the V-shaped locking member is for the actuator to enter to push the locking member.

[0011] As a further improvement of the present invention, it also includes a manual operation component, which includes a password component and an unlockable operating part; after the password component enters a correct password, the operating part is unlocked, and one end of the operating part abuts against the tail of the power part. By pressing the operating part downward, the power part can be swung, and then the actuator is driven to pry the locking part, so that the locking part is separated from the engaging part.

[0012] As a further improvement of the present invention, an elastic component is further provided in the carrying box, and the elastic component provides elastic force for resetting the power member; when the operating member releases the power member, the power member is reset by the elastic component.

[0013] As a further improvement of the present invention, the power member is installed in the carrying box via a bracket, the power member is swingably connected to the bracket, and the bracket is used to support the power member and allow it to swing.

[0014] As a further improvement of the present invention, the password assembly includes a fixed plate fixed in the carrying box, an unlocking plate slidably arranged on the fixed plate, and several buttons penetrated by the fixed plate, the operating member is located on the side of the unlocking plate, and the unlocking plate is maintained by a spring to move toward the operating member; the fixed plate is also provided with a locking member that can be rotated toward or away from the operating member, and the locking member is maintained by a torsion spring to move toward the operating member, and the operating member is locked by a locking groove provided on the operating member. When the locking member is embedded in the locking groove, the operating member is locked; an unlocking protrusion is provided on the unlocking plate, and a matching protrusion is provided on the locking member; when the button is pressed to enter the correct password, the unlocking plate is abutted against the operating member by elastic force, and the unlocking protrusion pushes away the matching protrusion to drive the locking member to rotate in a direction away from the operating member to unlock the operating member; the operating member is also provided with a guide protrusion, and 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 so that the button can change the password.

[0015] The beneficial effects of the present invention are as follows: the real-time monitoring of the pet's position is achieved through the cooperation between the positioning component and the user terminal. When the pet leaves the preset activity range, the restraint warning component creates discomfort stimulation for the pet through the clamping action. Compared with the solution in the prior art that only relies on sound alarms, the pet can be actively warned without continuous manual supervision, which effectively improves the reliability of the restraint on the pet's activity range, reduces the safety hazards of the pet leaving the supervision range, and enhances the supervision effect.

[0018] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0019] Reference Figure 1-8 As shown, A pet activity range restraint device includes a wearing unit 1 that can be worn on a pet, and the wearing unit 1 has built-in positioning components 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 cause discomfort stimulation to the pet, thereby providing a warning to the pet.

[0020] Structurally, the wearable unit 1 can take the form of a collar, chest strap, or other device, secured to the pet's neck or torso via buckles or Velcro. The positioning component can utilize a GNSS module (e.g., GPS, Beidou) and integrate a wireless communication module (e.g., Bluetooth, Wi-Fi) to establish a communication connection with a user terminal (e.g., a mobile app). The user terminal can preset a range of activity (e.g., via an electronic fence). The restraint warning component 12 is electrically connected to the positioning component via a wire to receive signals from the positioning component.

[0021] When a pet moves within a preset range, the positioning component transmits its location information in real time to the user terminal. The user terminal calculates the distance between the pet and the range boundary and feeds this information 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 structure (e.g., movable contact pads) within the restraint warning component 12 clamps toward the pet's body, contacting the pet's skin and creating a slight pressure sensation (non-injurious discomfort). The discomfort causes the pet to stop moving or return to the range. At this point, the positioning component receives a reset signal from the user terminal, and the restraint warning component 12 releases. This structure, which uses active physical stimulation to generate warnings, solves the problem of audible alarms being easily ignored by the pet and requiring manual intervention, thereby improving the timeliness and effectiveness of restraint.

[0022] In an optional specific scheme, the restraint warning component 12 includes a carrier box 121, a restraining member 122 passed through the carrier box 121, a locking member 123 for limiting the reverse loosening of the restraining member 122, and a contact member 124 rotatably mounted on the carrier box 121; the restraining member 122 is provided with a plurality of engaging portions 125 cooperating with the locking member 123, and the contact member 124 is located on the inner side of the restraining member 122; a driving component 126 and a control module are also provided in the carrier box 121, and the positioning component is integrated into the control module; when the pet leaves the preset activity range, the control module controls the driving component 126 to drive the contact member 124 to rotate, so that the contact member 124 forms a clamping effect on the pet.

[0023] The carrying case 121 can be a rigid plastic box, secured to the wearable unit 1. The restraint 122 can be a flexible belt, with both ends passing through the carrying case 121 to form a loop, adapting to pets of varying sizes. The engaging portion 125 consists of evenly distributed serrated protrusions on the surface of the restraint 122. The locking member 123 is a claw, installed within the carrying case 121 at a position corresponding to the engaging portion 125. The contact member 124 is a curved plastic or metal piece, hinged to the carrying case 121 via a pin. The control module is an MCU integrated on a PCB. The positioning components (GNSS module and wireless communication module) are soldered to the PCB. The drive component 126 is electrically connected to the control module via wires.

[0024] When a pet wears the device, the tightness is adjusted by pulling the restraint 122. The locking member 123 cooperates with the engaging portion 125 to prevent the restraint 122 from loosening, ensuring a secure fit. If the pet leaves the preset range, the control module receives a signal from the positioning assembly and outputs an electrical signal to the drive assembly 126. The drive assembly 126 drives the contact member 124 to rotate inward about the pin axis. The inner side of the contact member 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 member 124 is located inside the restraint 122, the restraining action of the restraint 122 enhances the clamping effect of the contact member 124, causing the pet to clearly sense discomfort and stop trying to escape.

[0025] Specifically, the driving assembly 126 includes a power member 1261, a transmission member 1262 and an actuator 1263. The actuator 1263 is connected to the transmission member 1262 through transmission. The transmission member 1262 is driven to move by the power member 1261 to drive the actuator 1263 to move; when the actuator 1263 moves, it pushes the contact member 124 to rotate, so that the contact member 124 clamps the pet; when the actuator 1263 moves in the opposite direction, the contact member 124 is released.

[0026] Power element 1261 can be a miniature DC motor, fixed to the inner wall of carrier box 121. Transmission element 1262 can be a gear set (a driving gear keyed to the motor output shaft, and a driven gear engaged with actuator 1263). Actuator 1263 is a metal push rod, one end of which is eccentrically hinged to the driven gear and the other end contacts the outer side of contact element 124. Power element 1261 is electrically connected to the control module via wires, receiving its control signals.

[0027] When the pet leaves the preset range, the control module controls power element 1261 to rotate forward, driving the driving gear. This in turn rotates the driven gear and, through the eccentric structure, pushes actuator 1263 in a straight line toward contact element 124. Actuator 1263 pushes contact element 124 to rotate about the pin, achieving clamping. If the pet stops moving due to discomfort, the control module controls power element 1261 to rotate backward, driving transmission element 1262 to drive actuator 1263 in the opposite direction. Contact element 124 rotates in the opposite direction to release under its own weight or the action of a return spring (which can be added between contact element 124 and carrier 121). This drive assembly 126 precisely controls the rotation of contact element 124 through the coordination of power element 1261, transmission element 1262, and actuator 1263. Switching between forward and reverse displacements allows for rapid switching between clamping and release, improving the device's responsiveness. Furthermore, the mechanical transmission method of transmission element 1262 is highly stable, making it suitable for the vibration environment encountered by pets.

[0028] Different from the above-mentioned drive component 126 structure, this solution is preferred, in which the power part 1261 is a motor, the transmission part 1262 is a screw rod, and the actuator 1263 is a slider; the slider is threadedly connected to the screw rod, and the motor drives the screw rod to rotate to drive the slider to slide, and the slider pushes the contact part 124 to rotate to achieve clamping; an elastic part 1264 is sleeved on the screw rod, and when the slider slides in the opposite direction, the elastic part 1264 pushes the contact part 124 to reset and release the pet.

[0029] One end of the screw rod is connected to the motor output shaft through a coupling or welded; the inner side of the slider is provided with an internal thread to cooperate with the screw rod, and also contacts the outer side of the contact member 124; the elastic member 1264 is a compression spring, which is sleeved on the screw rod, with one end abutting the contact member 124 and the other end abutting the position of the end of the motor.

[0030] When the pet leaves the range, the control module controls the motor to rotate forward, causing the screw to rotate and the slider to slide along the screw toward contact member 124. The slider pushes contact member 124 to rotate about the pin, clamping the pet while the slider compresses elastic member 1264. When the pet returns to the range, the motor reverses, causing the screw to drive the slider to slide in the opposite direction. Elastic member 1264 releases its elastic force, pushing contact member 124 back into position. Contact member 124 rotates in the opposite direction, releasing the pet. The threaded connection between the screw and the slider is self-locking, ensuring that the slider remains firmly in the clamped state and prevents loosening due to the pet's movement. The provision of elastic member 1264 also facilitates the smooth resetting of contact member 124.

[0031] In order to further unlock the restraining 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 restraining member 122: the actuator 1263 moves toward the locking member 123 and pushes the locking member 123, so that the locking member 123 is separated from the locking portion 125, thereby unlocking the restraining member 122.

[0032] Locking member 123 is a metal or plastic sheet, hinged at one end to carrier 121 and engaging with engaging portion 125 (a serrated protrusion) at the other end. The center portion of the sheet aligns with actuator 1263 (a slider). Actuator 1263 has a protrusion on the side facing locking member 123. The position of actuator 1263 aligns with locking member 123 and restraining member 122, ensuring contact with locking member 123 during movement.

[0033] When the tension of restraint 122 needs to be adjusted or the device removed, the control module receives an unlock signal from the user terminal (e.g., a user sends a command via an app) and controls power element 1261 to drive actuator 1263 toward locking element 123. Actuator 1263 pushes locking element 123, causing it to rotate about the hinge point, separating locking element 123 from engaging portion 125. At this point, restraint 122 can be pulled to adjust its length. After adjustment, actuator 1263 moves in the opposite direction, and locking element 123 returns to its original position under its own weight or the action of a return spring, reengaging engaging portion 125. This structure allows actuator 1263 to perform both the functions of clamping contact element 124 and unlocking restraint 122, simplifying the device structure and eliminating the need for a separate unlocking driver. Furthermore, unlocking is achieved through the displacement of actuator 1263, making operation more convenient and enhancing user convenience.

[0034] In order to facilitate the cooperation with the actuator 1263, the locking member 123 is a V-shaped structure, and its corner is installed on the carrier box 121 through a hinge axis, and the locking member 123 maintains the cooperation tendency with the locking part 125 through an elastic return member 1231; the groove of the V-shaped locking member 123 is for the actuator 1263 to enter to push the locking member 123.

[0035] The locking member 123 is V-shaped, hinged to the inner wall of the carrier box 121 at its corner via a pin. One end is a locking end (which mates with the locking portion 125), and the other is a force-bearing end, forming a groove between the two ends. The elastic return member 1231 is a torsion spring 215, which is mounted on the hinge axis. One end abuts the locking member 123 and the other abuts the inner wall of the carrier box 121, ensuring that the locking end always tends to move toward the locking portion 125. The end of the actuator 1263 (slider) can extend into the groove.

[0036] When restraint 122 is adjusted, actuator 1263 moves toward the groove and extends into it, pushing against the force-bearing end of locking member 123, causing locking member 123 to rotate about the hinge axis and separate the engaging end from engaging portion 125 (elastic return member 1231 is twisted and stored with force). When actuator 1263 is released, elastic return member 1231 releases its elastic force, causing locking member 123 to rotate in the opposite direction, reengaging the engaging end with engaging portion 125. The V-shaped structure of locking member 123 receives the pushing force of actuator 1263 through the groove, making engagement more convenient and stable.

[0037] In addition to the electric unlocking method, a manual unlocking method can also be added. Specifically, it also includes a manual operating component 2, which includes a password component 21 and an unlockable operating member 22; after the password component 21 enters the correct password, the operating member 22 is unlocked, and one end of the trigger member abuts against the tail of the power member 1261. By pressing down the operating member 22, the power member 1261 can swing, and then drive the executive member 1263 to pry the locking member 123, so that the locking member 123 is separated from the locking portion 125.

[0038] The password component 21 is a mechanical password lock or password button 213, which is installed on the surface of the carrier box 121; the operating member 22 is slidably installed on the side or end surface of the carrier box 121, with one end extending out of the carrier box 121 for pressing, and the other end is slidably connected to the inside of the carrier box 121 and abuts the tail of the power member 1261 (motor); the power member 1261 and the carrier box 121 are rotatably connected, allowing a certain angle of swing.

[0039] The user enters the correct password through password assembly 21, which unlocks operating member 22. The user then presses down on operating member 22, which pushes power member 1261 to swing. Power member 1261 then drives transmission member 1262 (e.g., a screw) to swing synchronously. Actuator 1263 (a slider) swings with transmission member 1262 and pries locking member 123, disengaging locking member 123 from engaging portion 125 and manually unlocking restraint member 122. This manual operating assembly 2 can serve as a backup for electronic control, enhancing the device's emergency response capabilities, preventing pets from being continuously restrained in the event of electronic control failure, and improving the device's safety and reliability.

[0040] Preferably, an elastic member 23 is further provided in the carrier box 121 to provide elastic force for the power member 1261 to return to its original position. When the operating member 22 releases the power member 1261, the power member 1261 is returned to its original position by the elastic member 23. The elastic member 23 can be an elastic sheet, one end of which is fixed in the carrier box 121 and the other end abuts against the power member 1261.

[0041] When the user presses down the operating part 22 to make the power part 1261 swing, the power part 1261 presses down the elastic part 23, and the elastic part 23 stores elastic potential energy; when the user releases the operating part 22, the elastic part 23 releases the potential energy, pushing the power part 1261 to swing back to the initial position, and the power part 1261 drives the transmission part 1262 and the executive part 1263 to reset synchronously, and the locking part 123 re-engages with the locking part 125 under the action of the elastic reset part 1231.

[0042] Preferably, the power member 1261 is installed in the carrier box 121 through a bracket 12611. The power member 1261 is swingably connected to the bracket 12611. The bracket 12611 is used to support the power member 1261 and allow it to swing.

[0043] Bracket 12611 is U-shaped and is fixed to the carrier box 121 by screws or integrally formed. Power member 1261 is hinged to bracket 12611, allowing power member 1261 to swing in a vertical plane around the rotation axis. This structure of bracket 12611 provides a certain support height, allowing power member 1261 to swing more smoothly.

[0044] In a specific solution, the password component 21 can be implemented in the following manner, referring to Figure 2 、 3 , 6, 7, 8 as shown: The password assembly 21 includes a fixed plate 211 fixed in the carrier box 121, an unlocking plate 212 slidably arranged on the fixed plate 211, and a plurality of buttons 213 passing through the locking plate. The operating member 22 is located on the side of the unlocking plate 212. The unlocking plate 212 is kept in a tendency to move toward the operating member 22 by a spring; the fixed plate 211 is also provided with a locking member 214 that can be rotated toward or away from the operating member 22. The locking member 214 is kept in a tendency to move toward the operating member 22 by a torsion spring 215. The operating member 22 is provided with a lock groove 216 for matching the locking member 214. When the locking member 214 is embedded in the lock groove 216, When the correct password is entered by pressing the button 213, the unlocking plate 212 abuts against the operating member 22 through elastic force, and the unlocking protrusion 217 pushes away the matching protrusion 218 to drive the locking member 214 to rotate in the direction away from the operating member 22, thereby unlocking the operating member 22; a guide protrusion 219 is also provided on the operating member 22, and 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, so that the button 213 can change the password.

[0045] The fixing plate 211 is a hard plastic plate fixed to the inner wall of the carrying box 121; the unlocking plate 212 is slidably connected to the fixing plate 211 through a slide rail or a guide component; the lower end of the button 213 cooperates with the unlocking plate 212 through a cam and a groove to form a password; one end of the spring is connected to the unlocking plate 212, and the other end abuts the inner wall of the carrying box 121; the locking piece 214 is hinged to the fixing plate 211 through a pin shaft, and the torsion spring 215 is sleeved on the pin shaft, with one end abutting the locking piece 214 and the other end abutting the fixing plate 211; the guide protrusion 219 is a wedge-shaped block on the side of the operating piece 22.

[0046] In the initial state, the locking member 214, under the action of the torsion spring 215, engages with the locking groove 216 of the operating member 22, locking the operating member 22. When the correct password is entered, the protrusion on the unlocking plate 212 mates with the groove on the key 213. The unlocking plate 212 moves under the action of the spring force. As the unlocking plate 212 moves, the protrusion inserts into the groove, restricting the rotation of the key 213. At the same time, the unlocking protrusion 217 on the unlocking plate 212 contacts the mating protrusion 218 of the locking member 214 and pushes the locking member 214 away. The locking member 214 rotates around the pin and disengages the locking groove 216, unlocking the operating member 22. When the user presses the operating member 22, the wedge-shaped surface of the guiding protrusion 219 pushes the unlocking plate 212 along the slide rail away from the operating member 22. The unlocking plate 212 releases the restriction on the key 213, allowing the user to press the key 213 again to set a new password. Once the setting is completed, the operating member 22 is released, and the unlocking plate 212 returns to its original position under the action of the spring, re-restraining the key 213. Password assembly 21 uses a mechanical structure to verify and unlock the password, offering simple operation and high security. Supporting a password change function enhances user flexibility and prevents security risks caused by password leaks. Furthermore, operating member 22 not only swings power member 1261 to unlock the key, but also changes the password for key 213. The password structure for key 213 can be adapted from the key 213 padlock disclosed in prior art publication CN120083417B.
