Description

Technical Field

[0001] The invention relates to the field of pet products, and in particular to a method for controlling the length of a traction rope used in a pet traction rope device. Background Art

[0002] With the improvement of living standards and the development of diversified interests, keeping pets has gradually become a hot topic in urban families. In the daily activities of pets going out, pet leashes are needed to limit the pets' activity space. Therefore, many types of pet leashes have appeared on the market.

[0003] Early pet leashes had fixed lengths of leashes, and users often had to follow their pets. Later, pet leashes with retractable leashes appeared. Usually, a button was provided on the leash to switch between two modes: one was a fixed-length leash, and the other was a freely retractable leash.

[0004] This type of pet leash is more practical than a fixed-length leash, but it also has certain disadvantages. The switching between the two modes requires manual adjustment by the user, especially when the pet rushes out of control. The user needs to react immediately to avoid the leash being suddenly lengthened by the pet due to untimely control. This requires the user to keep a close eye on the pet's movement status while out, which causes certain inconveniences for the user. Summary of the invention

[0005] In view of the above problems and technical requirements, the inventors have proposed a method for controlling the length of a traction rope for a pet leash. The technical solution of the present invention is as follows:

[0006] A method for controlling the length of a traction rope for a pet leash, the pet leash comprising a main body and a traction part, the traction part being detachably mounted on the main body, the main body being provided with a traction rope, a control unit, a main motor unit, a secondary motor unit, a main battery unit and an automatic winding unit, the main motor unit being electrically connected to the main battery unit, the control unit being respectively connected to the main motor unit, the secondary motor unit and the main battery unit by electrical signals, the main battery unit being electrically connected to the secondary motor unit, one end of the traction part being fixed to the pet, and the other end being fixed to the automatic winding unit through the traction rope, the rotating end of the main motor unit being transmission-connected to the automatic winding unit, the secondary motor unit being used to limit the rotation of the automatic winding unit, the control unit obtaining the current movement information of the pet through the rotation speed information of the rotating end of the main motor unit, and the control unit controlling the charging and discharging of the main battery unit according to the movement information.

[0007] A further technical solution is that the charging and discharging control of the main battery unit according to the motion information includes:

[0008] Determine that the moving direction of the traction part away from the main body part is a positive direction, and when the rotation speed of the rotating end of the main motor unit in the positive direction is lower than a preset rotation speed or when the rotating end of the main motor unit rotates in the reverse direction, the control unit controls the main motor unit to charge the main battery unit;

[0009] When the rotation speed of the main motor unit in the positive direction is higher than a preset speed, the control unit controls the main battery unit to discharge the auxiliary motor unit.

[0010] A further technical solution is that the control method further comprises:

[0011] The main body also includes an interaction unit, and the control unit is electrically connected to the interaction unit through the main battery unit. The control unit obtains connection status information between the traction part and the main body. When the traction part is separated from the main body, the automatic winding unit drives the rotating end of the main motor unit to rotate to generate an initial rotation signal. The control unit obtains the initial rotation signal and controls the interaction unit to transmit a first status signal to the outside.

[0012] A further technical solution is that the control method further comprises:

[0013] The separation time of the traction part and the main body part is determined. When the separation time reaches a first preset time, the control unit determines that the movement amount reaches the standard and controls the interaction unit to transmit a second state signal to the outside.

[0014] A further technical solution is that the control method further comprises:

[0015] When the traction part is separated from the main body and then reconnected with the main body, the connection time after reconnection is determined. When the connection time is greater than a second preset time, a sleep signal of the pet leash is determined, and the control unit obtains the sleep signal and shields the interaction unit from transmitting signals to the outside.

[0016] A further technical solution is that the main body is also provided with a charging interface, and the control unit obtains the current power status of the main battery unit. When the power status is lower than a preset power level, the control unit controls the interactive unit to transmit a charging signal to the outside, and the charging interface transmits the external AC power to the main battery unit.

[0017] A further technical solution is that the control method further comprises:

[0018] The traction unit further includes a position lamp and a secondary battery unit, the secondary battery unit being connected to the position lamp, and the main battery unit charging the secondary battery unit when the traction unit and the main body are fixedly mounted;

[0019] When the traction portion and the main body are separated, the position light emits light.

[0020] A further technical solution is that the main body also includes a gyroscope unit, the gyroscope unit obtains the shape information of the main body, and the control unit controls the auxiliary motor unit according to the shape information.

[0021] A further technical solution is that a gear unit is also provided in the main body, and the gear unit meshes and connects the rotating end of the main motor unit and the automatic winding unit, and the rotating speed of the rotating end of the main motor unit is higher than the rotating speed of the automatic winding unit.

[0022] The present invention proposes a method for controlling the length of a leash for a pet leash. When the automatic winding unit rotates, it drives the rotating end of the main motor unit to rotate. The electric energy generated by the main motor unit is stored in the main battery unit. At this time, the main battery performs charging control. In contrast to the main motor unit serving as a generator, the auxiliary motor unit is used to limit the rotation of the automatic winding unit. The auxiliary motor unit needs to rely on the energy in the main battery unit for drive control. At this time, the main battery unit performs discharge control. The control unit obtains the current movement information of the pet through the rotation speed information of the rotating end of the main motor unit. The control unit performs charging and discharging control on the main battery unit according to the movement information. The rotation state of the automatic winding unit can be reasonably controlled through charging and discharging control, thereby indirectly controlling the length of the leash and achieving the purpose of active control. Manual control by the user is not required, which is more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings.

[0029] A method for controlling the length of a leash for a pet leash, such as Figure 1 and 2 As shown, the pet leash comprises a main body 1 and a traction part 2, and the traction part 2 is detachably mounted on the main body 1. Figure 1 In the embodiment, the main body 1 and the traction part 2 are fixedly connected, and in Figure 2 In the figure, the main body 1 and the traction part 2 are separated. When the pet is pulled during outdoor activities, the traction part 2 is fixed on the pet, for example, on the pet's neck or on the pet's body, and the main body is in the user's hands. When the pet is pulled, the traction part can be combined with the main body again. It is easy to understand that the traction part 2 and the main body 1 are connected by a traction rope 3.

[0030] like Figure 3 and 4 As shown, a traction rope 3, a control unit 4, a main motor unit 5, an auxiliary motor unit 6, a main battery unit 7 and an automatic winding unit 8 are arranged in the main body 1. The control unit 4 can be in the form of a control chip or a circuit board structure with a control chip. The control unit can perform signal control on the circuit of the entire pet leash, such as obtaining signals for charge and discharge control, etc. The main motor unit 5 is a generator motor. The main motor unit 5 itself does not generate a driving force, but relies on an external driving force to drive the motor shaft of the main motor unit to rotate. The motor shaft is the rotating end, thereby generating electricity. In contrast to the main motor unit 5, the auxiliary motor unit 6 is a drive motor, and the drive motor relies on external electrical energy to actively rotate the motor shaft.

[0031] The main motor unit 5 is electrically connected to the main battery unit 7, and the electric energy generated by the main motor unit 5 is stored in the main battery unit 7. The control unit 4 is electrically connected to the main motor unit 5, the auxiliary motor unit 6 and the main battery unit 7 respectively, and the control unit 4 can control these three units. One end of the traction part 2 is fixed to the pet, and the other end is fixed to the automatic winding unit 8 through the traction rope 3. The automatic winding unit is a winder with a winding spring. When the traction part is moved away from the main body by an external force, the external force is greater than the elastic force of the winding spring, and the traction rope also moves with the traction part; and when the outdoor traction is ended, there is no external force on the traction part, and the automatic winding unit can rely on the elastic force of the winding spring to automatically recycle the traction rope.

[0032] The rotating end of the main motor unit 5 is connected to the automatic winding unit 8 by transmission. A common motor includes a stator and a rotor. When the motor is used as a generator, it is necessary to drive the stator and the rotor to generate a speed difference. A simple way is that the stator is fixed and the rotor rotates, or the stator rotates and the rotor is fixed. The rotating end of the present application can be a stator or a rotor, as long as the stator and the rotor are ensured to rotate relative to each other, so that when the automatic winding unit 8 rotates, the rotating end of the main motor unit 5 is driven to rotate, and the electric energy generated by the main motor unit 5 is stored in the main battery unit. At this time, the main battery performs charging control. In contrast to the main motor unit 5 as a generator, the auxiliary motor unit 6 is used to limit the rotation of the automatic winding unit 8. The auxiliary motor unit needs to rely on the energy in the main battery unit 7 for drive control. At this time, the main battery unit performs discharge control. The control unit obtains the current movement information of the pet through the rotation speed information of the rotating end of the main motor unit. The control unit controls the charge and discharge of the main battery unit according to the movement information. The rotation state of the automatic winding unit can be reasonably controlled through the charge and discharge control, thereby indirectly controlling the length of the traction rope to achieve the purpose of active control. It does not require manual control by the user, which is more convenient.

[0033] Furthermore, a gear unit 9 is also provided in the main body, and the gear unit 9 meshes and connects the rotating end of the main motor unit 5 and the automatic winding unit 8. The rotating speed of the rotating end of the main motor unit 5 is higher than the rotating speed of the automatic winding unit 8. The speed ratio can be further improved by the gear unit, and the power generation can be increased per unit speed.

[0034] like Figure 4 As shown, the specific control scheme is: determine that the movement direction of the traction part 2 away from the main body 1 is the positive direction, that is, the direction in which the user pulls the traction part 2 away from the main body 1, and the preset speed can be set according to the user's habits, for example, 0.8m / s or 1m / s. The control unit can obtain the speed information through the rotating end of the main motor unit that rotates synchronously with the traction rope, and the speed information is then converted into electric current. The control unit can further improve the recognition speed through the electric current.

[0035] When the rotational speed of the rotating end of the main motor unit 5 in the positive direction is lower than the preset speed or when the rotational end of the main motor unit 5 rotates in the reverse direction, the rotational speed in the positive direction is lower than the preset speed, which means that the moving speed of the traction part is still under the control of the user and there is no explosive surge. At this time, the main motor unit 5 is relied upon to control the charging of the main battery unit 7 to collect the energy of the movement of the traction part 2. Similarly, when the rotational end of the main motor unit 5 rotates in the reverse direction, the recovery state of the traction part 2 can be determined at this time. Even if the rotational speed is too large, there is no need to control it. The control unit still controls the main motor unit 5 to control the charging of the main battery unit 7.

[0036] When the rotation speed of the main motor unit 5 in the positive direction is higher than the preset speed, it means that the pet has entered a burst state, and the instantaneous speed is relatively fast, and it is difficult for the user to actively control it. At this time, the control unit controls the main battery unit to discharge the auxiliary motor unit, and the auxiliary motor unit 6 can stop the automatic winding unit, thereby avoiding the pet's burst state. The user does not need to pay attention to the current state of the pet at any time, which reduces the burden on the user to pull the pet.

[0037] Furthermore, the present application also includes a power saving function of performing periodic sleep and wake-up.

[0038] The method of the wake-up mode is as follows: the main body 1 also includes an interactive unit, and the control unit 4 is electrically connected to the interactive unit through the main battery unit 7. The interactive unit can interact with the outside world through light or sound. In this application, light is preferably selected as the interactive unit. The control unit obtains the connection status information between the traction part 2 and the main body 1. The function of obtaining the connection status information can be realized through sensors or contacts. In this application, the information is obtained through the electrical contacts between the main body 1 and the traction part 2. At the same time, when the traction part 2 is separated from the main body 1, the automatic winding unit 8 drives the rotating end of the main motor unit 5 to rotate to generate an initial rotation signal. The control unit 4 obtains the initial rotation signal and controls the interactive unit to transmit a first status signal to the outside. The first status signal is used as an indication signal, indicating that the current pet leash is in a working state. This application uses a dual judgment signal, one is the separation signal of the main body and the traction part, and the other is the rotation signal of the main motor unit, to avoid problems with one of the signals, resulting in inaccurate transmission of the interactive signal.

[0039] In the actual outdoor traction process, there is often a problem that the pet's exercise time is too long or too short. The outdoor exercise time is often a subjective judgment of the user. The pet may not exercise enough or exercise too much. The present application also provides a method for whether the amount of exercise is up to standard. Specifically: determine the separation time of the traction part 2 and the main body 1. When the separation time reaches a first preset time, for example, the first preset time is 30 minutes, and the separation time has exceeded 30 minutes, then it is determined that the amount of exercise has reached the standard. It can actually be flexibly set according to user needs. The control unit 4 determines that the amount of exercise has reached the standard and controls the interactive unit to transmit the second state signal to the outside. It should be noted that the first state signal and the second state signal are two different signals. The interactive unit can set lights in two different positions, or lights of different colors to reasonably express the two signals. The second state signal can indicate to the user that the amount of exercise has reached the standard and the current outdoor traction can be ended.

[0040] The last is the dormant state method. When the traction part 2 is separated from the main body 1 and then reconnected to the main body 1, the connection time after reconnection is determined. When the connection time is greater than the second preset time, the second preset time is usually set to three minutes. The dormant signal of the pet leash is determined, and the control unit obtains the dormant signal and shields the interaction unit from transmitting signals to the outside. Of course, the control unit 4 can not only reduce power consumption by shielding the outgoing signal of the interaction unit, but also by cutting off the communication signals between the units. Therefore, the dormant state can reasonably reduce power consumption and avoid wasting power when the pet leash is not in use.

[0041] Although the main motor unit 5 of the present application can charge the main battery unit 7, the actual charging efficiency will be affected by the frequency of use and user habits. In order to further avoid the problem of power exhaustion, the main body is also provided with a charging interface 10. The control unit obtains the current power status of the main battery unit 7. When the power status is lower than the preset power, the control unit controls the interactive unit to transmit a charging signal to the outside. The charging signal is usually a flashing alternating signal, which can promptly remind the user to perform charging operations. The charging interface 10 transmits the external AC power to the main battery unit.

[0042] like Figure 5 As shown, further, when the pet leash is used at night, even if the user pulls the leash, it is not easy to observe the position of the pet at this time. Therefore, in the present application, not only the main body can send out signals, but the traction part can also send out signals. The traction part also includes a position light 11 and a secondary battery unit 12. The secondary battery unit 12 is connected to the position light 11. When the traction part 2 and the main body 1 are fixedly installed, the main battery unit 7 charges the secondary battery unit 12. When the traction part 2 and the main body 1 are separated, the position light 11 is illuminated. Through the traction part with light, the current position information of the pet can be better obtained.

[0043] The main body 1 also includes a gyroscope unit, which obtains the morphological information of the main body 1. The control unit controls the sub-motor unit according to the morphological information. For example, when the user holds the pet leash in a vertical direction, it can be determined that traction is currently being performed, and the sub-motor unit does not drive; when the user holds the pet leash in a horizontal direction, the sub-motor unit performs a braking operation. Of course, it can actually be set according to the user and can be set for different angles.

[0044] The above is only a preferred embodiment of the present application, and the present invention is not limited to the above embodiments. It is understood that other improvements and changes directly derived or associated by those skilled in the art without departing from the spirit and concept of the present invention should be considered to be included in the protection scope of the present invention.
