Description

Technical Field

[0001] The present invention belongs to the field of rental equipment, and in particular relates to a mobile power rental device and a device and method for locking the mobile power. Background Art

[0002] At present, most of the mobile power rental equipment on the market uses a combination of metal ejectors and metal contacts to complete charging and identification. That is, a metal ejector is set in the charging module of the mobile power rental equipment, and a metal contact is set on the end face of the mobile power. When the mobile power is sent into the charging module, the metal contacts of the mobile power will eventually match the metal ejectors in the charging module, and the close contact between the two will complete the charging and identification of the mobile power by the charging module. If the metal contacts of the mobile power and the metal ejectors of the charging module fail to make full contact after the mobile power enters the charging module, charging and identification will fail.

[0003] Since the metal ejector pins are usually designed to be elastic, when the mobile power source is driven by the driving motor to the bottom of the charging module, the mobile power source will press down the metal ejector pins of the charging module, making the metal ejector pins compressed. However, when the driving motor stops running, the elastic force of the metal ejector pins will bounce the mobile power source away from its original position, which can easily lead to poor contact between the metal contacts of the mobile power source and the metal ejector pins of the charging module.

[0004] In order to solve this problem, a locking mechanism is usually added to the mobile module, such as using a solenoid valve, a buckle, etc. When the mobile power moves into place, the locking mechanism locks the position of the mobile power so that the metal contacts of the mobile power maintain close contact with the metal pins of the charging module to ensure smooth completion of the charging process and identity recognition.

[0005] Although the method of locking the mobile power supply using a locking mechanism can greatly improve the success rate of the charging process and is more conducive to completing the identity identification of the mobile power supply, this method will increase the structural complexity of the charging module and the manufacturing cost of the charging module. Summary of the invention

[0006] The purpose of the present invention is to provide a mobile power rental device and a device and method for locking a mobile power supply, aiming to solve the problem that the method of using a locking mechanism to lock the mobile power supply will increase the structural complexity of the charging module and the manufacturing cost of the charging module.

[0007] In a first aspect, the present invention provides a device for locking a mobile power supply for a mobile power supply rental device, the device comprising: a main controller, a locking controller, a drive motor, a sensor and a roller, wherein:

[0008] The main controller is used to control the locking controller to enable the mobile power supply to enter and exit the charging module and lock the mobile power supply, and control the charging module to charge and identify the mobile power supply;

[0009] A locking controller, which is electrically connected to the main controller and the drive motor, respectively, and is used to output two voltages to the drive motor under the control of the main controller, one of which is a working voltage for the drive motor to work normally, and the other is a voltage for the drive motor to lock the mobile power supply;

[0010] A drive motor is used to adjust the speed according to the voltage level under the control of the locking controller;

[0011] The sensor is used to sense whether the mobile power source has moved to a predetermined position and send a corresponding arrival signal to the main controller;

[0012] The roller is directly or indirectly connected to the driving motor and is used to realize forward and reverse rotation under the drive of the driving motor, thereby realizing the movement control of the mobile power supply entering and exiting the charging module.

[0013] In a second aspect, the present invention provides a mobile power rental device, including the device for locking the mobile power of the mobile power rental device mentioned above.

[0014] In a third aspect, the present invention provides a method for locking a mobile power supply by a mobile power supply rental device, the method comprising:

[0015] When the mobile power source enters the cavity of the charging module, the sensor at the entrance sends an induction signal to the main controller;

[0016] After receiving the sensing signal, the main controller controls the locking controller to output a working voltage to the drive motor to enable the drive motor to work normally;

[0017] The driving motor drives the roller to rotate, and drives the mobile power supply into the cavity of the charging module;

[0018] When the mobile power source moves to the bottom end of the cavity and presses the metal ejector pin, the mobile power source triggers the sensor at the bottom end of the cavity to send a signal of arrival to the main controller;

[0019] After receiving the arrival signal, the main controller controls the locking controller to output the voltage of the locking mobile power supply to the driving motor;

[0020] Driven by the voltage for locking the mobile power source, the driving motor always maintains the locking driving force applied to the roller to lock the mobile power source.

[0021] In the present invention, since the device for locking the mobile power supply of the mobile power supply rental equipment includes a locking controller, which is electrically connected to the main controller and the drive motor respectively, and is used to output two voltages to the drive motor under the control of the main controller, one of which is the working voltage for the drive motor to work normally, and the other is the voltage for the drive motor to lock the mobile power supply. Therefore, there is no need for a locking mechanism on the charging module, and only a locking controller needs to be added to achieve the position locking of the mobile power supply, so that the structure of the charging module is simple and the manufacturing cost is low.

[0028] The main controller 11 is used to control the locking controller to enable the mobile power source to enter and exit the charging module and lock the mobile power source, and to control the charging module to charge and identify the mobile power source.

[0029] The locking controller 12 is electrically connected to the main controller 11 and the drive motor 13, respectively, and is used to output two voltages to the drive motor 13 under the control of the main controller 11, one of which is a working voltage that enables the drive motor 13 to work normally, and the other is a voltage that enables the drive motor 13 to lock the mobile power supply. In the first embodiment of the present invention, the working voltage refers to a voltage that enables the drive motor to control the movement of the mobile power supply in and out of the charging module. The value of the voltage for locking the mobile power supply can be lower than the value of the working voltage.

[0030] The drive motor 13 is used to adjust the rotation speed according to the voltage under the control of the locking controller 12. In the first embodiment of the present invention, the drive motor 13 can be a DC motor or a stepper motor, and the holding torque of the stepper motor can be changed according to the change of the input voltage. Therefore, when the input locking voltage is maintained, it will not continue to heat up, thereby improving the service life of the drive motor.

[0031] The sensor 14 is used to sense whether the mobile power source has moved to a predetermined position and send a corresponding arrival signal to the main controller 11. In the first embodiment of the present invention, the sensor 14 can be a photoelectric sensor or a mechanical sensor.

[0032] The roller 15 is directly or indirectly connected to the driving motor 13 and is used to realize forward and reverse rotation under the drive of the driving motor 13, thereby realizing the movement control of the mobile power supply entering and exiting the charging module.

[0033] In the first embodiment of the present invention, the locking controller may be integrated into the main controller.

[0034] Embodiment 2:

[0035] See also Figure 2 The method for locking a mobile power supply by a mobile power supply rental device provided in the second embodiment of the present invention comprises the following steps: It should be noted that if there is substantially the same result, the method for locking a mobile power supply by a mobile power supply rental device of the present invention is not based on Figure 1 The process sequence shown is limited.

[0036] S101, when the mobile power source enters the cavity of the charging module, the sensor at the entrance sends an induction signal to the main controller;

[0037] S102, after receiving the sensing signal, the main controller controls the locking controller to output a working voltage to the driving motor to enable the driving motor to work normally;

[0038] S103, the driving motor drives the roller to rotate, and drives the mobile power supply into the cavity of the charging module;

[0039] S104, when the mobile power source moves to the bottom end of the cavity and presses the metal ejector pin, the mobile power source triggers the sensor at the bottom end of the cavity to send a signal of arrival to the main controller;

[0040] S105. After receiving the arrival signal, the main controller controls the locking controller to output a voltage to the drive motor to lock the mobile power supply; in the second embodiment of the present invention, the working voltage refers to a voltage that enables the drive motor to control the movement of the mobile power supply in and out of the charging module. The value of the voltage for locking the mobile power supply can be lower than the value of the working voltage. The voltage value for locking the mobile power supply makes the driving force generated by the drive motor meet the following conditions: the driving force cannot drive the roller to rotate, and the roller can maintain a rotational torque that can offset the ejection force of the metal top on the mobile power supply.

[0041] In the second embodiment of the present invention, S105 may specifically include the following steps:

[0042] After receiving the arrival signal, the main controller controls the locking controller to output the voltage of the locking mobile power supply to the driving motor while maintaining the output working voltage;

[0043] The driving motor is further driven by the working voltage and the voltage for locking the mobile power supply, thereby ensuring that the metal contact of the mobile power supply and the metal ejector pin are in close contact for a preset time;

[0044] After the preset time is reached, the main controller controls the locking controller to stop outputting the working voltage and maintains the uninterrupted output voltage of the locking mobile power supply.

[0045] In the second embodiment of the present invention, S105 may specifically include the following steps:

[0046] After receiving the arrival signal, the main controller controls the locking controller to stop outputting the working voltage and outputs the voltage of the locking mobile power supply to the driving motor.

[0047] S106. Under the drive of the voltage for locking the mobile power source, the driving motor keeps applying a locking driving force to the roller to lock the mobile power source. Although the driving force cannot drive the roller to rotate, the roller will maintain a rotational torque driven by the driving force to offset the ejection force of the metal ejector pin on the mobile power source, so that the mobile power source remains in the locked position and does not move, thereby ensuring close contact between the metal contact of the mobile power source and the metal ejector pin.

[0048] Embodiment three:

Therefore, there is no need for a locking mechanism on the charging module, and only a locking controller needs to be added to achieve the position locking of the mobile power supply, so that the structure of the charging module is simple and the manufacturing cost is low.
