Description

Technical Field

[0001] This invention relates to the field of new energy technology, specifically to a power transmission equipment and its control method. Background Technology

[0002] With the rapid promotion and application of new energy vehicles in the market, charging these vehicles via power transmission equipment has become an essential daily operation for new energy vehicle users. Power transmission equipment includes a power transmission gun and a power pile. The power pile inputs or outputs electrical energy through the power transmission gun. The power pile includes a gun holder. When not in use, the power transmission gun is plugged into the gun holder of the power pile. When power needs to be transferred between the new energy vehicle and the power transmission equipment, the power transmission gun is removed from the gun holder and connected to the vehicle's charging socket. When the power transfer between the new energy vehicle and the power transmission equipment is complete, the power transmission gun is removed from the vehicle's charging socket and moved back into the gun holder, ensuring proper connection.

[0003] In related technologies, to meet dustproof and waterproof requirements as well as stable connection requirements, the transmission gun and the gun holder of the transmission pile need to be fitted with a small gap. During the process of moving the transmission gun into or out of the gun holder, the user needs to provide a certain amount of insertion and extraction force. Inserting and removing the transmission gun is quite strenuous for users, and the transmission gun and transmission line have a certain weight, making the insertion and removal of the transmission gun and gun holder difficult for users with less physical strength. If the user lacks physical strength and fails to properly insert the transmission gun and gun holder, it is easy for the transmission gun to accidentally fall from the gun holder and be damaged, making the use of the transmission gun on the power transmission equipment inconvenient. Summary of the Invention

[0004] This application provides a power transmission device and its control method to facilitate the use of a power transmission gun.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: The first aspect of this application provides a power transmission device, including: Electricity transmission gun; A power transmission pile, which inputs or outputs electrical energy through the power transmission gun, the power transmission pile including a gun base for moving the power transmission gun in or out; A first magnetic device is disposed in one of the power transmission gun and the gun base, wherein multiple magnetic poles of the first magnetic device with opposite polarities are arranged alternately in the circumferential direction of the first axis in the same plane perpendicular to the first axis. A second magnetic device is disposed in one of the power transmission gun and the gun base. When the power transmission gun is moved into the gun base, the second magnetic device and the first magnetic device are arranged opposite each other along the first axis. The position of the second magnetic device relative to the first magnetic device in the circumferential direction along the first axis includes a first position that attracts each other and a second position that repels each other. A driving device is used to drive the first magnetic device or the second magnetic device to rotate, so that the position of the second magnetic device relative to the first magnetic device switches between the first position and the second position.

[0006] In this embodiment, the first magnetic device or the second magnetic device is driven to rotate by a driving device, so that the position of the second magnetic device relative to the first magnetic device switches between a first position and a second position, thereby attracting or repelling the first magnetic device and the second magnetic device, which helps the user to move the power transmission gun into or out of the gun holder, making it easier to insert and remove the power transmission gun and making it convenient to use the power transmission gun in various usage scenarios.

[0007] In some embodiments, the driving device is disposed on the gun base, one of the first magnetic device and the second magnetic device is disposed on the driving device, and the other of the first magnetic device and the second magnetic device is fixed to the power transmission gun.

[0008] In this embodiment, the space on the gun base is used to set up the driving device, which reduces the space occupied by the driving device in the power transmission gun and improves the structural compactness of the power transmission gun.

[0009] In some embodiments, both the first magnetic device and the second magnetic device are permanent magnets.

[0010] In this embodiment, under the same magnetic field strength, the volume of a permanent magnet is smaller than that of an electromagnet, reducing the space occupied by the first and second magnetic devices in the power transmission gun and gun base. The permanent magnet generates a magnetic field without the need for electricity, thus saving energy.

[0011] In some embodiments, the first magnetic device is disposed on the driving device, the first axis is the central axis through which the driving device drives the first magnetic device to rotate, and the second magnetic device is disposed on the power transmission gun. When the power transmission gun is moved into the gun holder, the polarities of the magnetic poles of the second magnetic device at one end along the first axis near the first magnetic device are the same.

[0012] In this embodiment, on the side of the power transmission gun facing the first magnetic device along the first axis, the second magnetic device only needs to be provided with one magnetic pole, which can reduce the space occupied by the second magnetic device in the power transmission gun.

[0013] In some embodiments, among the plurality of magnetic poles of the first magnetic device, at least one magnetic pole is a first magnetic pole and at least one magnetic pole is a second magnetic pole. The first magnetic pole and the second magnetic pole are arranged alternately circumferentially along the first axis in the same plane perpendicular to the first axis. The first magnetic pole and the second magnetic pole have opposite polarities. When the power transmission gun is moved into the gun holder, the magnetic pole of the second magnetic device near one end of the first magnetic device along the first axis is a third magnetic pole. The third magnetic pole attracts the first magnetic pole in a one-to-one correspondence and repels the second magnetic pole in a one-to-one correspondence.

[0014] In this embodiment of the application, the attraction and repulsion between the first magnetic device and the second magnetic device are increased when the number of magnetic poles is limited.

[0015] In some embodiments, the power transmission gun includes a plurality of terminals, and the second magnetic device includes a plurality of first magnetic elements, wherein, when the power transmission gun is moved into the gun holder, the first magnetic elements and the terminals are arranged alternately circumferentially along the first axis.

[0016] In this embodiment, the first magnetic element is arranged by utilizing the gap between two adjacent terminals along the first axis in the circumferential direction, thereby reducing the space occupied by the first magnetic device in the circumferential direction of the power transmission gun along the first axis and reducing the volume of the power transmission gun.

[0017] In some embodiments, the first magnetic device includes a second magnetic element and a third magnetic element, wherein a pair of magnetic poles of the second magnetic element and a pair of magnetic poles of the third magnetic element are arranged opposite to each other along the first axis, and the second magnetic element and the third magnetic element are arranged alternately circumferentially along the first axis, wherein the north pole of the second magnetic element points in the opposite direction to the south pole of the third magnetic element.

[0018] In this embodiment, the two magnetic poles of the first magnetic device are arranged circumferentially at intervals along the first axis in the same plane perpendicular to the first axis, thereby reducing the influence of magnetic poles on the second magnetic device that do not need to interact with the second magnetic device.

[0019] In some embodiments, the driving device includes: drive; A carrier is disposed on the driver so that the driver drives the carrier to rotate. The first magnetic device or the second magnetic device is mounted on the carrier. The first axis is the central axis of the driver driving the carrier to rotate.

[0020] In this embodiment, the carrier drives the first magnetic device or the second magnetic device to rotate, so that the first magnetic device and the second magnetic device attract or repel each other.

[0021] In some embodiments, the carrier is rotatably connected to the gun mount.

[0022] In this embodiment, the space on the gun base is used to set up the carrier and the driver, thereby reducing the space occupied by the carrier in the power transmission gun.

[0023] In some embodiments, the carrier has a limiting groove on one side of the radial direction along the first axis, and the gun holder includes a limiting member passing through the limiting groove along the first axis. When the second magnetic device is positioned relative to the first magnetic device at the first position, the limiting member abuts against the groove wall on one side of the limiting groove along the first axis in the circumferential direction. When the second magnetic device is positioned relative to the first magnetic device at the second position, the limiting member abuts against the groove wall on the other side of the limiting groove in the circumferential direction along the first axis.

[0024] In this embodiment, the rotation position of the carrier is controlled by limiting the rotation of the carrier through the limiting groove and the limiting member. The limiting groove and the limiting member have a simple structure and can control the first position and the second position relatively accurately.

[0025] In some embodiments, the gun base includes a first latch, and the power transmission gun includes: The gun body includes wiring terminals, through which the power transmission pile inputs or outputs electrical energy at least a portion of the wiring terminals; A gun hook is rotatably connected to the gun body and rotates about a second axis. The length direction of the gun hook intersects the second axis. The end of the gun hook facing the terminal along the length direction of the gun hook has a second latch. The second latch is used to lock the first latch to prevent the gun body from moving out of the gun base. An unlocking switch is movably mounted on the gun body. The unlocking switch and the second latch are located on opposite sides of the second axis along the length of the gun hook. The unlocking switch is used to drive the gun hook to rotate so that the second latch unlocks from the first latch.

[0026] In this embodiment, the movement of the gun hook is controlled by an unlocking switch, thereby locking or unlocking the power transmission gun with the gun hook. This can better control the connection state between the power transmission gun and the gun base and reduce the possibility of the power transmission gun falling off.

[0027] In some embodiments, the power transmission gun further includes an elastic element, the elastic element and the unlocking switch being located on opposite sides of the gun hook along the second axis in the circumferential direction. The power transmission equipment further includes a first trigger mounted on the gun base, the second latch being locked to the first latch under the elastic force of the elastic element and triggering the first trigger.

[0028] In this embodiment of the application, the position of the second latch can be determined by the first trigger, thereby determining the connection state between the power transmission gun and the gun base.

[0029] In some embodiments, the power transmission gun further includes a second trigger located on the side of the second axis along the length direction of the gun hook toward the unlocking switch. The unlocking switch and the second trigger are respectively located on opposite sides of the gun hook along the circumference of the second axis. The unlocking switch drives the gun hook to rotate to trigger the second trigger. The second trigger is used to generate a trigger signal when the power transmission gun is connected to the vehicle socket and the unlocking switch is activated. The terminals of the power transmission pile include a protective ground terminal and a first signal terminal. The second trigger is triggered and conducts the protective ground terminal and the first signal terminal when the unlocking switch is activated.

[0030] In this embodiment, the unlocking switch controls the second trigger, thereby controlling the protective ground terminal and the first signal terminal to conduct, and the state of the unlocking switch can be determined according to the conduction status of the protective ground terminal and the first signal terminal.

[0031] In some embodiments, the power transmission equipment further includes a controller, the controller being configured to: Determine the state of the power transmission gun; Based on the state of the power transmission gun, the driving device is controlled to drive the first magnetic device or the second magnetic device to rotate, so that the position of the second magnetic device relative to the first magnetic device switches between the first position and the second position.

[0032] In this embodiment, the power transmission equipment can automatically control the position of the second magnetic device relative to the first magnetic device according to the state of the power transmission gun, assisting in inserting and removing the power transmission gun, and facilitating the movement of the power transmission gun into or out of the gun holder.

[0033] A second aspect of this application provides a control method for a power transmission equipment, applied to the power transmission equipment; the control method includes: Determine the state of the power transmission gun; Based on the state of the power transmission gun, the driving device is controlled to drive the first magnetic device or the second magnetic device to rotate, so that the position of the second magnetic device relative to the first magnetic device switches between the first position and the second position.

[0034] In this embodiment, the power transmission equipment can automatically control the position of the second magnetic device relative to the first magnetic device according to the state of the power transmission gun, assisting in inserting and removing the power transmission gun, and facilitating the movement of the power transmission gun into or out of the gun holder.

[0035] In some embodiments, the gun base has a first latch, the gun hook has a second latch, an unlocking switch is used to drive the gun hook to rotate so that the second latch is unlocked from the first latch, a first trigger is installed on the gun base, and the second latch is locked to the first latch under the elastic force of the elastic element and triggers the first trigger. Based on the state of the power transmission gun, controlling the drive device to drive the first magnetic device or the second magnetic device to rotate, so that the position of the second magnetic device relative to the first magnetic device switches between the first position and the second position, including: When the first trigger remains in the state before triggering, the power transmission gun is in a state of being separated from the power transmission pile, and the driving device is controlled to drive the first magnetic device or the second magnetic device to rotate, so that the position of the second magnetic device relative to the first magnetic device is at the first position; When the first trigger remains in the triggered state, the power transmission gun is in the state of being plugged into the gun base, and the driving device is controlled to drive the first magnetic device or the second magnetic device to rotate, so that the position of the second magnetic device relative to the first magnetic device is at the first position; When the first trigger switches from the triggered state to the pre-triggered state, the power transmission gun is in the unplugged state, and the driving device is controlled to drive the first magnetic device or the second magnetic device to rotate, so that the position of the second magnetic device relative to the first magnetic device is at the second position.

[0036] In this embodiment, the state of the power transmission gun is determined according to the state of the first trigger, thereby controlling the attraction or repulsion between the first magnetic device and the second magnetic device, making it easier to insert and remove the power transmission gun, and making the connection between the power transmission gun and the gun base stable.

[0037] In some embodiments, the gun base has a first latch, the gun hook has a second latch, and an unlocking switch is used to drive the gun hook to rotate so that the second latch is unlocked from the first latch. The gun hook is rotatably connected to the gun body and rotates about a second axis. The unlocking switch drives the gun hook to rotate to trigger the second trigger. The second trigger is used to generate a trigger signal when the power transmission gun is connected to the vehicle socket and the unlocking switch is activated. The terminals of the power transmission pile include a protective ground terminal and a first signal terminal. The second trigger is triggered and conducts the protective ground terminal and the first signal terminal when the unlocking switch is activated. Determining the state of the power transmission gun includes: When the first signal terminal of the power transmission pile is connected to the protective ground terminal of the power transmission pile, the first signal terminal of the vehicle socket is disconnected from the protective ground terminal of the vehicle socket, and the first communication terminal of the vehicle socket is disconnected from the first communication terminal of the power transmission pile, it is determined that the power transmission gun is in the first state. When the first signal terminal of the power transmission pile is connected to the protective ground terminal of the power transmission pile, the first signal terminal of the vehicle socket is disconnected from the protective ground terminal of the vehicle socket, and the first communication terminal of the vehicle socket is connected to the first communication terminal of the power transmission pile, it is determined that the power transmission gun is in the second state. The control method further includes: When the duration of the power transmission gun in the first state or the second state exceeds the first duration, the power transmission equipment issues a prompt.

[0038] In this embodiment, the continuity of the wiring terminals of the power transmission pile and the vehicle socket is used to determine whether the power transmission gun is properly plugged into the vehicle socket, and the user is reminded as needed to assist the user in plugging the power transmission gun into place.

[0039] In some embodiments, a first trigger is mounted on the gun base, and the second latch is locked to the first latch under the elastic force of the elastic member, thereby triggering the first trigger; Determining the state of the power transmission gun also includes: When the first trigger remains in the state before triggering, and the first signal terminal of the power transmission pile is disconnected from the protective ground terminal of the power transmission pile, the first signal terminal of the vehicle socket is connected to the protective ground terminal of the vehicle socket, and the first communication terminal of the vehicle socket is connected to the first communication terminal of the power transmission pile, it is determined that the power transmission gun is in the state of being plugged into the vehicle socket. If the first trigger remains in the state before triggering, and the first signal terminal of the power transmission pile is disconnected from the protective ground terminal of the power transmission pile, the first signal terminal of the vehicle socket is disconnected from the protective ground terminal of the vehicle socket, and the first communication terminal of the vehicle socket is disconnected from the first communication terminal of the power transmission pile, then the power transmission gun is determined to be in the third state. The control method further includes: When the duration of the power transmission gun in the third state is longer than the duration of the second state, the power transmission equipment issues a prompt.

[0040] In this embodiment, the position of the power transmission gun is determined based on the triggering state of the first trigger and the continuity between the wiring terminals of the power transmission pile and the wiring terminals of the vehicle socket. The user is then reminded as needed to assist the user in placing the power transmission gun in the correct position.

[0041] The beneficial effects of this invention are: In the power transmission equipment of this application embodiment, the position of the second magnetic device relative to the first magnetic device along the circumferential direction of the first axis includes a first position of mutual attraction and a second position of mutual repulsion. The driving device is used to drive the first magnetic device or the second magnetic device to rotate, so that the position of the second magnetic device relative to the first magnetic device switches between the first position and the second position. When it is necessary to remove the power transmission gun from the gun holder, the driving device can make the position of the first magnetic device relative to the second magnetic device in the second position, and the first magnetic device and the second magnetic device repel each other, so that there is a repulsive force between the power transmission gun and the gun holder, making it easier to pull out the gun and facilitating the removal of the power transmission gun from the gun holder. When it is necessary to move the power transmission gun into the gun holder, the driving device can make the position of the first magnetic device relative to the second magnetic device in the first position, and the first magnetic device and the second magnetic device attract each other, so that there is an attractive force between the power transmission gun and the gun holder, making it easier to insert the gun and facilitating the removal of the power transmission gun into the gun holder. The power transmission gun is convenient to use. After the power transmission gun is moved into the gun holder, stability between the power transmission gun and the gun holder is required. This is achieved by keeping the first magnetic device in a first position relative to the second magnetic device. The first and second magnetic devices attract each other, creating an attractive force between the power transmission gun and the gun holder, reducing the risk of damage from accidental falls. A drive device rotates either the first or second magnetic device, switching the position of the second magnetic device relative to the first magnetic device between the first and second positions. This allows the first and second magnetic devices to attract or repel each other, assisting the user in moving the power transmission gun into or out of the gun holder. This makes inserting and removing the power transmission gun easier and more convenient for use in various scenarios. Attached Figure Description

It should be understood that the preferred embodiments are only for illustrating the present invention and not for limiting the scope of protection of the present invention.

[0045] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0046] This application provides a power transmission device; please refer to [link / reference]. Figures 1-9 The power transmission equipment includes a power transmission gun 2, a power transmission pile 10, a first magnetic device 3, a second magnetic device 4, and a drive device 5. The power transmission pile 10 inputs or outputs electrical energy through the power transmission gun 2. The power transmission pile 10 includes a gun base 1 for moving the power transmission gun 2 in or out. The first magnetic device 3 is disposed in one of the power transmission gun 2 and the gun base 1. Multiple magnetic poles of the first magnetic device 3 with opposite polarities are alternately arranged circumferentially along the first axis 11 in the same plane perpendicular to the first axis 11. The second magnetic device 4 is disposed in the other of the power transmission gun 2 and the gun base 1. When the power transmission gun 2 moves into the gun base 1, the second magnetic device 4 and the first magnetic device 3 are arranged opposite each other along the first axis 11. The position of the second magnetic device 4 relative to the first magnetic device 3 along the circumferential direction of the first axis 11 includes a first position of mutual attraction and a second position of mutual repulsion. The drive device 5 is used to drive the first magnetic device 3 or the second magnetic device 4 to rotate, so that the position of the second magnetic device 4 relative to the first magnetic device 3 switches between the first position and the second position.

[0047] It should be noted that when the power transmission gun 2 is moved into the gun holder 1, the first magnetic device 3 is in the first position relative to the second magnetic device 4.

[0048] It should be noted that the gun holder 1 is used to place the electric gun 2, and no electrical energy is transmitted between the gun holder 1 and the electric gun 2.

[0049] It should be noted that the multiple magnetic poles of the first magnetic device 3 with opposite polarities are arranged alternately along the circumference of the first axis 11 in the same plane perpendicular to the first axis 11, meaning that the multiple magnetic poles of the first magnetic device 3 are arranged along the circumference of the first axis 11 in the same plane perpendicular to the first axis 11, and the polarities of two adjacent magnetic poles along the circumference of the first axis 11 in the same plane perpendicular to the first axis 11 are opposite.

[0050] It should be noted that the multiple magnetic poles of the first magnetic device 3 with opposite polarities are arranged alternately along the circumference of the first axis 11 in the same plane perpendicular to the first axis 11. This means that the first plane is perpendicular to the first axis 11, the first plane intersects with the first magnetic device 3, and the multiple magnetic poles of the first magnetic device 3 with opposite polarities at the intersection with the first plane are arranged alternately along the circumference of the first axis 11 on the first plane.

[0051] For example, the power transmission pile 10 outputs electrical energy to the vehicle through the power transmission gun 2 to charge the vehicle.

[0052] For example, the vehicle's electrical energy can be input into the power grid via the power transmission gun 2 to supply power to the power grid.

[0053] For example, the first magnetic device 3 is disposed on the power transmission gun 2, and the second magnetic device 4 is disposed on the gun base 1.

[0054] For example, the second magnetic device 4 is disposed on the power transmission gun 2, and the first magnetic device 3 is disposed on the gun base 1.

[0055] For example, the driving device 5 is used to drive the first magnetic device 3 to rotate so that the position of the second magnetic device 4 relative to the first magnetic device 3 switches between a first position and a second position.

[0056] For example, the driving device 5 is used to drive the second magnetic device 4 to rotate so that the position of the second magnetic device 4 relative to the first magnetic device 3 switches between a first position and a second position.

[0057] For example, the power transmission equipment also includes a conductive cable, the two ends of which are connected to the power transmission pile 10 and the power transmission gun 2, respectively.

[0058] For example, the locations where the conductive cables connect to the power transmission pile 10 and where the gun base 1 is located are arranged at intervals.

[0059] In this embodiment, the position of the second magnetic device 4 relative to the first magnetic device 3 along the circumferential direction of the first axis 11 includes a first position of mutual attraction and a second position of mutual repulsion. The driving device 5 is used to drive the first magnetic device 3 or the second magnetic device 4 to rotate, so that the position of the second magnetic device 4 relative to the first magnetic device 3 switches between the first position and the second position. When it is necessary to remove the power transmission gun 2 from the gun holder 1, the driving device 5 can make the position of the first magnetic device 3 relative to the second magnetic device 4 in the second position, and the first magnetic device 3 and the second magnetic device 4 repel each other, so that there is a repulsive force between the power transmission gun 2 and the gun holder 1, making it easier to pull out the gun and facilitating the removal of the power transmission gun 2 from the gun holder 1. When it is necessary to move the power transmission gun 2 into the gun holder 1, the driving device 5 can make the position of the first magnetic device 3 relative to the second magnetic device 4 in the first position, and the first magnetic device 3 and the second magnetic device 4 attract each other, so that there is an attractive force between the power transmission gun 2 and the gun holder 1, making it easier to insert the gun and facilitating the removal of the power transmission gun 2 into the gun holder 1. The power transmission gun 2 is convenient to use. After the power transmission gun 2 is moved into the gun holder 1, it is necessary to maintain stability between the power transmission gun 2 and the gun holder 1. This ensures that the first magnetic device 3 is held in a first position relative to the second magnetic device 4. The first magnetic device 3 and the second magnetic device 4 attract each other, creating an attractive force between the power transmission gun 2 and the gun holder 1, reducing the risk of the power transmission gun 2 accidentally falling off the gun holder 1 and getting damaged. The driving device 5 drives the first magnetic device 3 or the second magnetic device 4 to rotate, causing the position of the second magnetic device 4 relative to the first magnetic device 3 to switch between a first position and a second position. This allows the first magnetic device 3 and the second magnetic device 4 to attract or repel each other, assisting the user in moving the power transmission gun 2 into or out of the gun holder 1, making it easier to insert and remove the power transmission gun 2 and facilitating its use in various scenarios.

[0060] In some embodiments, please refer to Figures 1-9 The driving device 5 is disposed on the gun base 1, one of the first magnetic device 3 and the second magnetic device 4 is disposed on the driving device 5, and the other of the first magnetic device 3 and the second magnetic device 4 is fixed to the power transmission gun 2.

[0061] For example, the first magnetic device 3 is disposed on the driving device 5, and the second magnetic device 4 is fixed to the power transmission gun 2.

[0062] For example, the second magnetic device 4 is disposed on the driving device 5, and the first magnetic device 3 is fixed to the power transmission gun 2.

[0063] In this embodiment, the driving device 5 is disposed on the gun base 1, one of the first magnetic device 3 and the second magnetic device 4 is disposed on the driving device 5, and the other of the first magnetic device 3 and the second magnetic device 4 is fixed to the power transmission gun 2. The driving device 5 is disposed in the space on the gun base 1, which reduces the space occupied by the driving device 5 in the power transmission gun 2, improves the structural compactness of the power transmission gun 2, and is conducive to the user's operation of the power transmission gun 2. The installation of the first magnetic device 3 or the second magnetic device 4 on the power transmission gun 2 does not require much modification to the structure of the power transmission gun 2.

[0064] It is understood that the drive device 5 is not limited to being disposed on the gun base 1. Exemplarily, the drive device 5 is disposed on the power transmission gun 2.

[0065] In some embodiments, the first magnetic device 3 and the second magnetic device 4 are both permanent magnets.

[0066] In this embodiment, both the first magnetic device 3 and the second magnetic device 4 are permanent magnets. Under the same magnetic field strength, the volume of a permanent magnet is smaller than that of an electromagnet, reducing the space occupied by the first magnetic device 3 and the second magnetic device 4 in the power transmission gun 2 and the gun base 1, thus reducing the overall volume of the power transmission gun 2 and the gun base 1. The permanent magnet generates a magnetic field without requiring electricity. When the power transmission gun 2 needs magnetic attraction between the gun base 1, the first magnetic device 3 can be held in a first position relative to the second magnetic device 4 so that the first magnetic device 3 and the second magnetic device 4 attract each other, eliminating the need to energize the first magnetic device 3 and the second magnetic device 4, thereby saving energy.

[0067] It is understood that the first magnetic device 3 and the second magnetic device 4 are not limited to being permanent magnets. For example, the first magnetic device 3 and the second magnetic device 4 are both electromagnets.

[0068] In some embodiments, please refer to Figures 1-9 The first magnetic device 3 is disposed on the driving device 5, and the first axis 11 is the central axis of the driving device 5 driving the first magnetic device 3 to rotate. The second magnetic device 4 is disposed on the power transmission gun 2. When the power transmission gun 2 moves into the gun base 1, the polarity of the magnetic poles of the second magnetic device 4 along the first axis 11 near the end of the first magnetic device 3 is the same.

[0069] For example, when the second magnetic device 4 includes a plurality of first magnetic elements 41, the north poles of all the first magnetic elements 41 are directed toward the first magnetic device 3 along the first axis 11, and the south poles of all the first magnetic elements 41 are directed away from the first magnetic device 3 along the first axis 11; or, the south poles of all the first magnetic elements 41 are directed toward the first magnetic device 3 along the first axis 11, and the north poles of all the first magnetic elements 41 are directed away from the first magnetic device 3 along the first axis 11.

[0070] For example, when the second magnetic device 4 includes a first magnetic element 41, the north and south poles of the first magnetic element 41 are arranged along the first axis 11.

[0071] In this embodiment, when the power transmission gun 2 is moved into the gun holder 1, the magnetic poles of the second magnetic device 4 at the end of the first magnetic device 3 along the first axis 11 have the same polarity. The driving device 5 drives the first magnetic device 3 to rotate, so that the magnetic poles of the first magnetic device 3 match the magnetic poles at one end of the second magnetic device 4. On the side of the power transmission gun 2 facing the first magnetic device 3 along the first axis 11, the second magnetic device 4 only needs to be provided with one type of magnetic pole at the end of the first magnetic device 3 along the first axis 11, which can reduce the space occupied by the second magnetic device 4 in the power transmission gun 2.

[0072] It is understandable that when the power transmission gun 2 is moved into the gun holder 1, the polarity of the magnetic poles of the second magnetic device 4 near the end of the first magnetic device 3 along the first axis 11 is not limited to being the same.

[0073] For example, when the power transmission gun 2 is moved into the gun holder 1, the south and north poles of the second magnetic device 4 are arranged circumferentially on the same plane perpendicular to the first axis 11.

[0074] For example, the second magnetic device 4 includes a magnetic element whose south and north poles are arranged circumferentially along the first axis 11 in the same plane perpendicular to the first axis 11.

[0075] In some embodiments, please refer to Figures 1-9 In the first magnetic device 3, at least one magnetic pole is the first magnetic pole and at least one magnetic pole is the second magnetic pole. The first magnetic pole and the second magnetic pole are arranged alternately along the circumference of the first magnetic axis 11 in the same plane perpendicular to the first axis 11. The polarities of the first magnetic pole and the second magnetic pole are opposite. When the power transmission gun 2 is moved into the gun holder 1, the magnetic pole of the second magnetic device 4 near the end of the first magnetic device 3 along the first axis 11 is the third magnetic pole. The third magnetic pole and the first magnetic pole are attracted to each other in a one-to-one correspondence, and the third magnetic pole and the second magnetic pole are repelled in a one-to-one correspondence.

[0076] It should be noted that the alternating arrangement of the first magnetic pole and the second magnetic pole in the same plane perpendicular to the first axis 11 along the circumference of the first axis 11 can be the alternating arrangement of the first magnetic pole and the second magnetic pole of the same magnetic element in the same plane perpendicular to the first axis 11 along the circumference of the first axis 11, or it can be the alternating arrangement of the first magnetic pole and the second magnetic pole of different magnetic elements in the same plane perpendicular to the first axis 11 along the circumference of the first axis 11.

[0077] For example, please refer to Figure 1 and Figure 2The first magnetic device 3 includes a plurality of magnetic elements, which are circumferentially spaced along the first axis 11. The first magnetic pole and the second magnetic pole of the magnetic elements are arranged along the first axis 11. The first magnetic pole of some magnetic elements faces the second magnetic device 4 along the first axis 11, and the second magnetic pole of other magnetic elements faces the second magnetic device 4 along the first axis 11.

[0078] For example, please refer to Figure 9 The first magnetic device 3 includes a plurality of magnetic elements, which are arranged circumferentially along the first axis 11. Each magnetic element includes a first magnetic pole and a second magnetic pole. The first magnetic pole and the second magnetic pole of the magnetic element are arranged circumferentially along the first axis 11 in the same plane perpendicular to the first axis 11. The direction from the first magnetic pole to the second magnetic pole intersects the first axis 11. The plurality of magnetic elements are arranged circumferentially along the first axis 11.

[0079] For example, the first magnetic device 3 includes at least two first magnetic poles and at least two second magnetic poles.

[0080] For example, the first magnetic pole is the south pole, the second magnetic pole is the north pole, and the third magnetic pole is the north pole.

[0081] For example, the first magnetic pole is the North Pole, the second magnetic pole is the South Pole, and the third magnetic pole is the South Pole.

[0082] The North Pole is the magnetic pole shown as N in the figure.

[0083] The South Pole is the magnetic pole shown as S in the figure.

[0084] In this embodiment of the application, when the power transmission gun 2 is moved into the gun holder 1, the third magnetic pole of the second magnetic device 4 is attracted to the first magnetic pole in a one-to-one correspondence, and the third magnetic pole and the second magnetic pole are repelled in a one-to-one correspondence. The magnetic poles of the first magnetic device 3 and the second magnetic device 4 correspond to each other. When the number of magnetic poles is limited, the attraction and repulsion between the first magnetic device 3 and the second magnetic device 4 are increased.

[0085] It is understood that the third magnetic pole attracts, but is not limited to, the first magnetic pole in a one-to-one correspondence, and the third magnetic pole repels, but is not limited to, the second magnetic pole in a one-to-one correspondence. For example, the number of third magnetic poles is less than the number of first magnetic poles.

[0086] In some embodiments, please refer to Figure 3 and Figure 8 The power transmission gun 2 includes multiple terminals 211, and the second magnetic device 4 includes multiple first magnetic elements 41. When the power transmission gun 2 is moved into the gun base 1, the first magnetic elements 41 and the terminals 211 are arranged alternately along the circumference of the first axis 11.

[0087] For example, the first magnetic element 41 may be two, four, or six.

[0088] In this embodiment, when the power transmission gun 2 is moved into the gun holder 1, the first magnetic element 41 and the terminal block 211 are alternately arranged along the circumference of the first axis 11. The first magnetic element 41 is arranged using the gap between two adjacent terminals 211 along the circumference of the first axis 11, reducing the space occupied by the first magnetic device 3 along the circumference of the power transmission gun 2 and reducing the volume of the power transmission gun 2. Given the structural constraints of the power transmission gun 2, the more uniform arrangement of the terminal block 211 and the first magnetic element 41 along the circumference of the first axis 11 results in more uniform attractive and repulsive forces on the power transmission gun 2.

[0089] It is understood that the first magnetic element 41 and the terminal 211 are not limited to being arranged alternately circumferentially along the first axis 11. Exemplarily, the first magnetic element 41 is located radially inside the terminal 211 along the first axis 11.

[0090] In some embodiments, please refer to Figures 1-8 The first magnetic device 3 includes a second magnetic element 31 and a third magnetic element 32. A pair of magnetic poles of the second magnetic element 31 and a pair of magnetic poles of the third magnetic element 32 are arranged opposite to each other along the first axis 11. The second magnetic element 31 and the third magnetic element 32 are arranged alternately along the circumference of the first axis 11. The direction in which the north pole of the second magnetic element 31 points to the south pole and the direction in which the north pole of the third magnetic element 32 points to the south pole are opposite.

[0091] For example, the second magnetic device 4 includes a plurality of first magnetic elements 41 arranged circumferentially spaced along the first axis 11.

[0092] For example, the number of second magnetic elements 31 is the same as the number of third magnetic elements 32, and the number of first magnetic elements 41 is the same as the number of second magnetic elements 31.

[0093] For example, the number of first magnetic elements 41 is equal to the sum of the number of second magnetic elements 31 and the number of third magnetic elements 32.

[0094] For example, the south and north poles of the first magnetic element 41 are arranged opposite each other along the first axis 11, and the north poles of all the first magnetic elements 41 point in the same direction to the south pole.

[0095] For example, the south and north poles of the first magnetic element 41 are arranged opposite to each other along the first axis 11, and the direction in which the north pole of a portion of the first magnetic element 41 points to the south pole is opposite to the direction in which the north pole of another portion of the first magnetic element 41 points to the south pole.

[0096] In this embodiment, the second magnetic element 31 and the third magnetic element 32 are arranged alternately along the circumference of the first axis 11. The north pole of the second magnetic element 31 points in the opposite direction to the south pole, and the north pole of the third magnetic element 32 points in the opposite direction to the south pole. The two magnetic poles of the first magnetic device 3 are arranged at intervals along the circumference of the first axis 11 in the same plane perpendicular to the first axis 11. When the relative position of the first magnetic device 3 and the second magnetic device 4 is in the first position, one magnetic pole of the first magnetic device 3 attracts the second magnetic device 4, reducing the influence of the repulsive force generated by the other magnetic pole of the first magnetic device 3 on the second magnetic device 4. When the relative position of the first magnetic device 3 and the second magnetic device 4 is in the second position, one magnetic pole of the first magnetic device 3 repels the second magnetic device 4, reducing the influence of the attractive force generated by the other magnetic pole of the first magnetic device 3 on the second magnetic device 4.

[0097] It is understood that the pair of magnetic poles of the second magnetic element 31 and the pair of magnetic poles of the third magnetic element 32 are not limited to being arranged opposite each other along the first axis 11. Exemplarily, the pair of magnetic poles of the second magnetic element 31 and the pair of magnetic poles of the third magnetic element 32 are both arranged circumferentially along the first axis 11.

[0098] In some embodiments, please refer to Figure 1 , Figure 2 , Figure 7 and Figure 9 The driving device 5 includes a driver 51 and a carrier 52. The carrier 52 is disposed on the driver 51 so that the driver 51 drives the carrier 52 to rotate. A first magnetic device 3 or a second magnetic device 4 is mounted on the carrier 52. The first axis 11 is the central axis of the driver 51 driving the carrier 52 to rotate.

[0099] For example, driver 51 is a motor.

[0100] For example, the first magnetic device 3 is mounted on the carrier 52.

[0101] For example, the second magnetic device 4 is mounted on the carrier 52.

[0102] In this embodiment, the carrier 52 is disposed on the driver 51 so that the driver 51 drives the carrier 52 to rotate. The first magnetic device 3 or the second magnetic device 4 is installed on the carrier 52 so that the carrier 52 drives the first magnetic device 3 or the second magnetic device 4 to rotate, so that the first magnetic device 3 and the second magnetic device 4 attract or repel each other.

[0103] It is understood that the first axis 11 is not limited to the central axis that drives the carrier 52 to rotate as the driver 51. Exemplarily, the first axis 11 intersects the central axis that drives the carrier 52 to rotate as the driver 51.

[0104] In some embodiments, please refer to Figure 1 , Figure 2 , Figure 7 and Figure 9 The support member 52 is rotatably connected to the gun base 1.

[0105] It should be noted that the driver 51 is located in the gun mount 1.

[0106] For example, the driver 51 is located on one side of the carrier 52 along the radial direction of the first axis 11.

[0107] For example, the driver 51 engages with the carrier 52.

[0108] In this embodiment, the support member 52 is rotatably connected to the gun base 1. The support member 52 and the driver 51 are arranged in the space on the gun base 1, reducing the space occupied by the support member 52 in the power transmission gun 2. The driver 51 is arranged on the gun base 1 of the power transmission pile 10, which facilitates the electrical connection between the driver 51 and the power transmission pile 10.

[0109] It is understood that the carrier 52 is not limited to being rotatably connected to the gun base 1. Exemplarily, the carrier 52 is rotatably connected to the power transmission gun 2.

[0110] In some embodiments, please refer to Figure 1 , Figure 2 , Figure 7 and Figure 9 The support member 52 has a limiting groove 521 on one side of the radial direction along the first axis 11. The gun base 1 includes a limiting member 12 that passes through the limiting groove 521 along the first axis 11. When the second magnetic device 4 is in the first position relative to the first magnetic device 3, the limiting member 12 abuts against the groove wall of the limiting groove 521 along the circumferential direction along the first axis 11. When the second magnetic device 4 is in the second position relative to the first magnetic device 3, the limiting member 12 abuts against the groove wall of the limiting groove 521 along the other circumferential direction along the first axis 11.

[0111] In this embodiment, when the second magnetic device 4 is positioned relative to the first magnetic device 3 at the first position, the limiting member 12 abuts against the limiting groove 521 along one side of the circumferential groove wall of the first axis 11; when the second magnetic device 4 is positioned relative to the first magnetic device 3 at the second position, the limiting member 12 abuts against the limiting groove 521 along the other side of the circumferential groove wall of the first axis 11. The rotation position of the bearing member 52 is controlled by limiting the rotation of the bearing member 52 through the limiting groove 521 and the limiting member 12. The limiting groove 521 and the limiting member 12 have simple structures and can control the first position and the second position relatively accurately, which is beneficial to better control the mutual attraction or repulsion between the first magnetic device 3 and the second magnetic device 4, making the power transmission equipment convenient to use.

[0112] It is understood that the carrier 52 is not limited to having a limiting groove 521, and the gun holder 1 is not limited to including a limiting member 12 that passes through the limiting groove 521 along the first axis 11. Exemplarily, the rotation angle of the carrier 52 is controlled by controlling the number of rotations of the driver 51.

[0113] In some embodiments, please refer to Figures 4-6 The gun base 1 includes a first latch 13, and the power transmission gun 2 includes a gun body 21, a gun hook 22, and an unlocking switch 23. The gun body 21 includes a terminal block 211, and the power transmission pile 10 inputs or outputs electrical energy through at least a portion of the terminal block 211. The gun hook 22 is rotatably connected to the gun body 21 and rotates about a second axis 212. The length direction of the gun hook 22 intersects the second axis 212. The end of the gun hook 22 facing the terminal block 211 along the length direction of the gun hook 22 has a second latch 221. The second latch 221 is used to lock the first latch 13 to restrict the gun body 21 from moving out of the gun base 1. The unlocking switch 23 is movably mounted on the gun body 21. The unlocking switch 23 and the second latch 221 are located on both sides of the second axis 212 along the length direction of the gun hook 22, respectively. The unlocking switch 23 is used to drive the gun hook 22 to rotate so that the second latch 221 is unlocked from the first latch 13.

[0114] For example, the second magnetic device 4 is disposed on the gun body 21.

[0115] For example, the gun body 21 includes a gun head and a gun body connected to the gun head. The gun head and the gun body are arranged in a preset direction. The gun head is inserted into the gun base 1. The second magnetic device 4 is disposed on the side of the gun head away from the gun body along the preset direction. When the gun head moves into the gun base 1, the preset direction is parallel to the first axis 11, and the gun body is at least partially located outside the gun base 1.

[0116] For example, terminal 211 is located on the gun head.

[0117] For example, the second magnetic device 4 is disposed on the gun head.

[0118] In this embodiment, the second latch 221 is used to lock the first latch 13 to restrict the gun body 21 from moving out of the gun base 1. The unlocking switch 23 is used to drive the gun hook 22 to rotate so that the second latch 221 is unlocked from the first latch 13. By controlling the movement of the gun hook 22 through the unlocking switch 23, the power transmission gun 2 is locked or unlocked with the gun hook 22, which can better control the connection state between the power transmission gun 2 and the gun base 1 and reduce the possibility of the power transmission gun 2 falling off.

[0119] It is understood that the gun base 1 is not limited to having the first latch 13, and the gun hook 22 is not limited to having the second latch 221. Exemplarily, the magnetic attraction of the first magnetic device 3 and the second magnetic device 4 can prevent the power transmission gun 2 from detaching from the gun base 1.

[0120] In some embodiments, the power transmission gun 2 further includes an elastic element 24, the elastic element 24 and the unlocking switch 23 are respectively located on opposite sides of the gun hook 22 along the second axis 212 in the circumferential direction, and the power transmission equipment further includes a first trigger 6 installed on the gun base 1, the second latch 221 is locked with the first latch 13 under the elastic force of the elastic element 24 and triggers the first trigger 6.

[0121] For example, the elastic element 24 is a spring.

[0122] For example, the elastic element 24 is an elastic rope.

[0123] For example, the elastic element 24 is a rubber pad that can deform and rebound.

[0124] For example, the elastic element 24 is located on one side of the unlocking switch 23 along the moving direction of the unlocking switch 23, and the gun hook 22 abuts between the elastic element 24 and the unlocking switch 23 along the moving direction of the unlocking switch 23.

[0125] In this embodiment of the application, the power transmission equipment also includes a first trigger 6 installed on the gun base 1. The second latch 221 is locked with the first latch 13 under the elastic force of the elastic member 24 and triggers the first trigger 6. When the first trigger 6 is triggered, the power transmission gun 2 is inserted into the gun base 1. When the first trigger 6 is not triggered, the power transmission gun 2 is separated from the gun base 1. The position of the second latch 221 can be determined by the first trigger 6, thereby determining the insertion state of the power transmission gun 2 and the gun base 1.

[0126] It is understood that the elastic element 24 and the unlocking switch 23 are not limited to being located on opposite sides of the hook 22 along the second axis 212. Exemplarily, the elastic element 24 and the unlocking switch 23 are located on one side of the hook 22 along the second axis 212.

[0127] It is understood that the power transmission gun 2 is not limited to having an elastic element 24. For example, the unlocking switch 23 achieves reset through its own elastic deformation.

[0128] In some embodiments, the power transmission gun 2 further includes a second trigger 7, which is located on one side of the second axis 212 along the length of the hook 22 toward the unlocking switch 23. The unlocking switch 23 and the second trigger 7 are respectively located on opposite sides of the hook 22 along the circumference of the second axis 212. The unlocking switch 23 drives the hook 22 to rotate to trigger the second trigger 7. The second trigger 7 is used to generate a trigger signal when the power transmission gun 2 is connected to the vehicle socket 100 and the unlocking switch 23 is activated. The terminals of the power transmission pile 10 include a protective ground terminal and a first signal terminal. The second trigger 7 is triggered and conducts the protective ground terminal and the first signal terminal when the unlocking switch 23 is activated.

[0129] It should be noted that the protective ground terminal of the transmission pile 10 is the PE terminal, and the first signal terminal of the transmission pile 10 is the CC terminal.

[0130] It should be noted that vehicle socket 100 is the vehicle's power supply interface.

[0131] In this embodiment, the second trigger 7 is triggered and connects the protective ground terminal and the first signal terminal when the unlocking switch 23 is activated. The second trigger 7 is controlled by the unlocking switch 23, thereby controlling the connection of the protective ground terminal and the first signal terminal. The state of the unlocking switch 23 can be determined according to the connection status of the protective ground terminal and the first signal terminal.

[0132] It is understood that the second trigger 7 is not limited to being located on the side of the second axis 212 along the length of the hook 22 towards the unlocking switch 23, and the unlocking switch 23 and the second trigger 7 are not limited to being located on opposite sides of the hook 22 along the circumference of the second axis 212. Exemplarily, the second trigger 7 is located on the side of the second axis 212 away from the unlocking switch 23 along the length of the hook 22, and the unlocking switch 23 and the second trigger 7 are located on one side of the hook 22 along the circumference of the second axis 212.

[0133] In some embodiments, please refer to Figure 10 The number of terminals 211 is multiple, including a first terminal, a second terminal, and a third terminal. The transmission pile 10 terminals include a protective ground terminal, a first signal terminal, and a first communication terminal. The transmission equipment also includes a protective conductor, a first line 271, a first voltage divider resistor 25, a second voltage divider resistor 26, a common line 274, a second line 272, and a third line 273. The protective conductor is electrically connected to the first terminal and the protective ground terminal, respectively. The two ends of the first line 271 are electrically connected to the second terminal and the protective conductor, respectively. The first voltage divider resistor 25 and the second voltage divider resistor 26 are connected in series with the first line 271, and the first voltage divider resistor 25 and the second voltage divider resistor 26 are connected in series with the first line 271. The two-divider resistor 26 is located between the first voltage divider resistor 25 and the protective conductor. One end of the common line 274 is electrically connected to the first line 271 between the second voltage divider resistor 26 and the protective conductor. The other end of the common line 274 is electrically connected to the common terminal of the second trigger 7. One end of the second line 272 is electrically connected to the first line 271 between the first voltage divider resistor 25 and the second voltage divider resistor 26.

One end of the third line 273 is electrically connected to the normally open contact of the second trigger 7. The other end of the third line 273 is electrically connected to the first signal terminal of the power transmission pile 10. The third terminal is electrically connected to the first communication terminal.

[0134] The protective conductor (PE conductor) grounds the metal casing of electrical equipment, ensuring that current can safely flow into the earth in the event of a fault, preventing threats to personal safety caused by leakage or short circuit in electrical equipment.

[0135] It should be noted that the first terminal is used for electrical connection with the protective earth terminal (PE terminal) of the vehicle socket 100.

[0136] It should be noted that the second terminal is used for electrical connection with the first signal terminal (CC terminal) of the vehicle socket 100.

[0146] In this embodiment, the power transmission equipment can automatically control the position of the second magnetic device 4 relative to the first magnetic device 3 according to the state of the power transmission gun 2, assisting in inserting and removing the power transmission gun 2, so that the power transmission gun 2 can be moved into or out of the gun holder 1.

[0147] This application provides a control method for power transmission equipment. Please refer to [link / reference]. Figures 1-3 and Figures 10-13 The control methods are applied to power transmission equipment; the control methods include: Step S1: Determine the status of the power transmission gun.

[0148] Step S2: Based on the state of the power transmission gun, control the drive device to drive the first magnetic device or the second magnetic device to rotate, so that the position of the second magnetic device relative to the first magnetic device switches between the first position and the second position.

[0149] In this embodiment, the state of the power transmission gun 2 is determined. Based on the state of the power transmission gun 2, the drive device 5 is controlled to drive the first magnetic device 3 or the second magnetic device 4 to rotate, so that the position of the second magnetic device 4 relative to the first magnetic device 3 switches between a first position and a second position. The power transmission equipment can automatically control the position of the second magnetic device 4 relative to the first magnetic device 3 according to the state of the power transmission gun 2, assisting in inserting and removing the power transmission gun 2, and facilitating the movement of the power transmission gun 2 into or out of the gun holder 1.

[0153] Step S23: When the first trigger switches from the triggered state to the pre-triggered state, the power supply gun is in the unplugged state. The control drive device drives the first magnetic device or the second magnetic device to rotate, so that the position of the second magnetic device relative to the first magnetic device is the second position.

[0154] It should be noted that when the first trigger 6 is triggered by an external force, the first trigger 6 remains in the state before triggering, which means that the first trigger 6 is in the state where no external force is applied.

[0155] It should be noted that the state of the first trigger 6 after being triggered refers to the state of the first trigger 6 under the action of an external force.

[0156] For example, the second latch 221 triggers the first trigger 6.

[0157] For example, the first trigger 6 is a normally open switch. The state before the first trigger 6 is triggered is that the first trigger 6 is in the open state, and the state after the first trigger 6 is triggered is that the first trigger 6 is in the closed state.

[0158] For example, the first trigger 6 is a normally closed switch. The state before the first trigger 6 is triggered is that the first trigger 6 is in the closed state, and the state after the first trigger 6 is triggered is that the first trigger 6 is in the open state after being subjected to external force.

[0159] It should be noted that "power transmission gun 2 is in the unplugged state" means that power transmission gun 2 has not yet been pulled out of the gun holder 1, and power transmission gun 2 is at least partially located in the gun holder 1.

[0160] In this embodiment, when the first trigger 6 remains in the triggered state, the power transmission gun 2 is in the plugged-in state with the gun holder 1. The control drive device 5 drives the first magnetic device 3 or the second magnetic device 4 to rotate, so that the position of the second magnetic device 4 relative to the first magnetic device 3 is in the first position. The magnetic attraction between the first magnetic device 3 and the second magnetic device 4 stabilizes the plugging between the power transmission gun 2 and the gun holder 1. When the first trigger 6 switches from the triggered state to the pre-triggered state, the unlocking switch 23 of the power transmission gun 2 located in the gun holder 1 is pressed, and the power transmission gun 2 is in the unplugged state. It is determined that the user needs to unplug the power transmission gun 2. The control drive device 5 drives the first magnetic device 3 or the second magnetic device 4 to rotate, so that the position of the second magnetic device 4 relative to the first magnetic device 3 is in the second position, so that the first magnetic device 3 and the second magnetic device 4 repel each other, assisting the user in unplugging the power transmission gun 2 from the gun holder 1. When the first trigger 6 remains in the state before triggering, and the second latch 221 does not apply external force to the first trigger 6, it indicates that the power transmission gun 2 is not located in the gun holder 1 and the power transmission gun 2 is in a state separated from the power transmission pile 10. The control drive device 5 drives the first magnetic device 3 or the second magnetic device 4 to rotate so that the position of the second magnetic device 4 relative to the first magnetic device 3 is in the first position, so that the first magnetic device 3 and the second magnetic device 4 are in a position where they can attract each other. When the power transmission gun 2 moves into the gun holder 1, the first magnetic device 3 and the second magnetic device 4 can generate attraction in time to assist the power transmission gun 2 in inserting into the gun holder 1.

[0161] It is understood that when the first trigger 6 remains in its pre-trigger state, it is not limited to controlling the drive device 5 to drive the first magnetic device 3 or the second magnetic device 4 to rotate to the first position. For example, when the first trigger 6 remains in its pre-trigger state, the drive device 5 remains unchanged.

[0162] In some embodiments, please refer to Figure 13 The control methods also include: If the duration of the timer from the switch from the first trigger to the state before the trigger is greater than or equal to the third duration, the first trigger is determined to remain in the state before the trigger.

[0163] For example, the third duration is equal to 5 seconds.

[0164] In some embodiments, please refer to Figure 13 According to the state of the power transmission gun 2, the control drive device 5 drives the first magnetic device 3 or the second magnetic device 4 to rotate, so that the position of the second magnetic device 4 relative to the first magnetic device 3 switches between a first position and a second position, and also includes: Step S24: When the time taken from switching from the state before triggering to the state before triggering is less than the third time, the first trigger switches from the state before triggering to the state after triggering, and the first signal terminal of the power transmission pile is disconnected from the protective ground terminal of the power transmission pile, the control drive device drives the first magnetic device or the second magnetic device to rotate, so that the position of the first magnetic device relative to the second magnetic device is the first position.

[0165] It should be noted that when the first trigger 6 switches from the state before triggering to the state after triggering, it means that the second latch 221 triggers the first trigger 6, and the power transmission gun 2 is being inserted into the gun base 1.

[0166] In this embodiment of the application, when the time taken from switching from the state before the first trigger 6 to the state after the trigger is less than the third time, the first trigger 6 switches from the state before the trigger to the state after the trigger, and the first signal terminal of the power transmission pile 10 is disconnected from the protective ground terminal of the power transmission pile 10, the power transmission gun 2 is pulled out from the gun holder 1 and then inserted back into the gun holder 1 within the third time.

[0167] In some embodiments, the gun base 1 has a first latch 13, the gun hook 22 has a second latch 221, and the unlocking switch 23 is used to drive the gun hook 22 to rotate so that the second latch 221 is unlocked from the first latch 13. The gun hook 22 is rotatably connected to the gun body 21 and rotates about the second axis 212. The unlocking switch 23 drives the gun hook 22 to rotate to trigger the second trigger 7. The second trigger 7 is used to generate a trigger signal when the power transmission gun 2 is connected to the vehicle socket 100 and the unlocking switch 23 is activated. The terminals of the power transmission pile 10 include a protective ground terminal and a first signal terminal. The second trigger 7 is triggered and conducts the protective ground terminal and the first signal terminal when the unlocking switch 23 is activated.

[0168] In some embodiments, please refer to Figures 10-14 Determine the status of power transmission gun 2, including: Step S11: When the first signal terminal of the power transmission pile is connected to the protective ground terminal of the power transmission pile, the first signal terminal of the vehicle socket is disconnected from the protective ground terminal of the vehicle socket, and the first communication terminal of the vehicle socket is disconnected from the first communication terminal of the power transmission pile, it is determined that the power transmission gun is in the first state.

[0169] Step S12: When the first signal terminal of the power transmission pile is connected to the protective ground terminal of the power transmission pile, the first signal terminal of the vehicle socket is disconnected from the protective ground terminal of the vehicle socket, and the first communication terminal of the vehicle socket is connected to the first communication terminal of the power transmission pile, it is determined that the power transmission gun is in the second state.

[0170] Control methods also include: Step S3: When the duration of the power transmission gun in the first or second state exceeds the first duration, the power transmission equipment issues a prompt.

[0171] For example, the first duration is equal to 5 minutes.

[0172] It should be noted that the state of the first signal terminal of the power transmission pile 10 being connected or disconnected from the protective ground terminal of the power transmission pile 10 indicates the movement state of the unlocking switch 23.

[0173] It should be noted that when the first signal terminal of the vehicle socket 100 is connected to the protective ground terminal of the vehicle socket 100, electrical energy is transmitted between the vehicle socket 100 and the power transmission pile 10. When the first signal terminal of the vehicle socket 100 is disconnected from the protective ground terminal of the vehicle socket 100, no electrical energy is transmitted between the vehicle socket 100 and the power transmission pile 10.

[0174] It should be noted that the on or off state of the first communication terminal of the vehicle socket 100 and the first communication terminal of the power transmission pile 10 indicates the connection state between the power transmission gun 2 and the vehicle socket 100.

[0175] It should be noted that the timing of the first duration begins when the first trigger 6 switches from the state after being triggered to the state before being triggered.

[0176] For example, the power transmission equipment issues a voice prompt saying "Please check if the power transmission gun is connected correctly".

[0177] For example, the power transmission equipment sends a message to the user's mobile device prompting them to "Please check if the power transmission gun is plugged in correctly".

[0178] In this embodiment of the application, when the first signal terminal of the power transmission pile 10 is connected to the protective ground terminal of the power transmission pile 10, the first signal terminal of the vehicle socket 100 is disconnected from the protective ground terminal of the vehicle socket 100, and the first communication terminal of the vehicle socket 100 is disconnected from the first communication terminal of the power transmission pile 10, it indicates that the unlocking switch 23 of the power transmission gun 2 is pressed, the power transmission gun 2 is not inserted into the gun holder 1 and is not inserted into the vehicle socket 100, and it is determined that the power transmission gun 2 is in the first state, and the power transmission gun 2 is not connected to the gun holder 1 or the vehicle socket 100. When the first signal terminal of the power transmission pile 10 is connected to the protective ground terminal of the power transmission pile 10, the first signal terminal of the vehicle socket 100 is disconnected from the protective ground terminal of the vehicle socket 100, and the first communication terminal of the vehicle socket 100 is connected to the first communication terminal of the power transmission pile 10, it indicates that the unlocking switch 23 of the power transmission gun 2 is pressed, the power transmission gun 2 is inserted into the socket in the vehicle, and there is no power transmission between the power transmission gun 2 and the vehicle socket 100. It is determined that the power transmission gun 2 is in the second state, and the power transmission gun 2 is not properly connected to the vehicle socket 100. When the duration of the power transmission gun 2 in the first state or the second state is longer than the first duration, the power transmission equipment issues a prompt to remind the user that the power transmission gun 2 is not properly connected, and assists the user in properly connecting the power transmission gun 2.

[0179] In some embodiments, please refer to Figures 10-15Determining the status of power transmission gun 2 also includes: Step S13: When the first trigger remains in the state before triggering, and the first signal terminal of the power transmission pile is disconnected from the protective ground terminal of the power transmission pile, the first signal terminal of the vehicle socket is connected to the protective ground terminal of the vehicle socket, and the first communication terminal of the vehicle socket is connected to the first communication terminal of the power transmission pile, it is determined that the power transmission gun is in the state of being plugged into the vehicle socket.

[0180] Step S14: When the first trigger remains in the state before triggering, and the first signal terminal of the power transmission pile is disconnected from the protective ground terminal of the power transmission pile, the first signal terminal of the vehicle socket is disconnected from the protective ground terminal of the vehicle socket, and the first communication terminal of the vehicle socket is disconnected from the first communication terminal of the power transmission pile, it is determined that the power transmission gun is in the third state.

[0181] Control methods also include: Step S4: When the duration of the power transmission gun in the third state is longer than the duration of the second state, the power transmission equipment issues a prompt.

[0182] For example, the second duration is equal to 5 minutes.

[0183] It should be noted that the timing of the second duration begins when the first trigger 6 switches from the state after being triggered to the state before being triggered.

[0184] In this embodiment, when the first trigger 6 remains in its pre-trigger state, if the first signal terminal of the power transmission pile 10 is disconnected from the protective ground terminal of the power transmission pile 10, the first signal terminal of the vehicle socket 100 is disconnected from the protective ground terminal of the vehicle socket 100, and the first communication terminal of the vehicle socket 100 is disconnected from the first communication terminal of the power transmission pile 10, it is determined that the power transmission gun 2 is in the third state. The first trigger 6 on the gun holder 1 is not triggered, the power transmission gun 2 is not inserted into the gun holder 1, the unlocking switch 23 is not subjected to external force, the power transmission gun 2 is not inserted into the gun holder 1 and not inserted into the vehicle socket 100, and the power transmission gun 2 may be placed in other locations besides the gun holder 1 and the vehicle socket 100. When the duration of the power transmission gun 2 in the third state is longer than the second duration, the power transmission equipment issues a prompt to remind the user that the position of the power transmission gun 2 is incorrect, reducing the possibility that the power transmission gun 2 may be forgotten in other locations outside the gun holder 1.
