Description

Technical Field

[0001] The present application belongs to the technical field of chargers, and specifically relates to a vehicle charger. Background Art

[0002] Nowadays, drivers and passengers often use onboard chargers to connect to the vehicle's power socket to charge their mobile phones and other electronic devices. The onboard charger includes a power plug that connects to the power socket and a charging interface for connecting to the electronic device. The power plug and the charging interface are connected by a charging cable. When charging an electronic device, the driver and passenger connect the plug to the power socket and the charging interface to the electronic device. After charging, to avoid the impact of continuous charging on the electronic device's battery, the driver and passenger need to separate the charging interface from the electronic device. The charging cable will be placed on the path from the charging socket to the electronic device. When the person moves or takes or puts items, the charging cable will touch the charging cable and shift, causing the charging interface to change position, such as sliding under the seat or getting stuck in the gap between the seat and the armrest box. When the driver and passenger need to charge the charging device, they need to spend a lot of energy to find the charging interface. At this time, the driver and passenger will grab the charging cable and pull it to quickly find the charging interface, causing the charging interface to collide with the seat or other components in the vehicle, causing damage to the charging interface. Moreover, when the electronic device to be charged is a mobile phone, the mobile phone needs to be placed on the side of the steering wheel to provide navigation services for the driver. When the charging port is separated from the mobile phone, the charging port will fall under the steering wheel, and the charging cable will fall loosely in the car. The charging cable is messy and may even be entangled with the gear lever during the falling process or when people touch the charging cable, further affecting the driver's driving experience.

[0003] There is a charger with a recyclable charging cable that uses a flat scroll spring and a ratchet mechanism. When the charging cable is pulled, the spring contracts. After pressing a button or pulling the charging cable again to unlock the ratchet, the spring rebounds and drives the charging cable to rotate in the opposite direction and recycle. As a result, the retraction force after unlocking cannot be controlled, which can easily cause the charging port to collide with internal vehicle components during the retraction process. Summary of the Invention

[0004] The present application provides a vehicle charger to solve the technical problem that the recovery force of existing vehicle chargers cannot be controlled, which easily causes the charging interface to collide with vehicle components during the recovery process and cause damage.

[0005] The first purpose of this application is to provide a vehicle charger, the technical solution adopted is:

The vehicle-mounted charger also includes a wire member arranged corresponding to the connecting hole, the wire member can rotate relative to the support member, the charging cable includes a connecting section extending in an arc shape through the connecting hole, the wire member is hooked with the connecting section, and the wire member rotates relative to the support member to extend the length of the connecting section to accommodate the charging cable.

[0007] The vehicle charger in the first object of this application also includes the following additional technical features:

[0008] The guide wire member comprises an arc-shaped guide member and an annular guide sleeve rotatably arranged on the guide member, and the annular guide sleeve is hooked with the connecting section.

[0009] The connecting hole extends along a preset direction, the connecting section includes two transition sections arranged opposite to each other along the preset direction and a curved section connecting the two transition sections, and the axis of the guide extends along the preset direction.

[0010] The length of the connecting hole is greater than the sum of the axial thickness of the wire member and the diameters of the two connecting sections.

[0011] The vehicle charger also includes a fixing seat connected to the power interface and a rotating member arranged on the fixing seat, a supporting member is arranged on the fixing seat, the rotating member rotates around the axis of the supporting member, the accommodating hole extends to the fixing seat, and the wire member is arranged on the rotating member.

[0012] Along the preset direction, the support member is provided with multiple connection holes, the rotating member is provided with multiple wire members, and two guide members are provided at one end of the support member away from the fixed seat. The two guide members are arranged relative to each other with the axis of the support member. The guide member can be rotatably set on the support member, and the guide member is provided with a guide groove that cooperates with the charging cable.

[0013] The connecting hole includes two hole walls arranged opposite to each other along the circumference of the support member. The rotating member rotates along the first direction to lengthen the connecting section. The hole wall located in the front along the first direction is inclined toward the first direction, and the hole wall located in the rear is inclined in the opposite direction of the first direction.

[0014] The vehicle charger also includes a fixed base connected to the power connection interface and a protective member arranged along the circumference of the fixed base. The protective member extends along a preset direction to form a protective cavity. The vehicle charger also includes a rotating member that can be set on the fixed base and a toggle member set on the rotating member. The wire member is set on the rotating member.

[0015] The rotating member is provided with a mounting hole, and the toggle member is movably arranged in the mounting hole. The vehicle charger also includes a first protective cover detachably arranged at one end of the protective member away from the fixed seat. The toggle member is connected to the rotating member through an elastic reset member. The first protective cover can push against the toggle member so that the toggle member is located in the protective cavity.

[0016] A second object of the present application is to provide a method for determining the length of a charging cable, using the on-board charger described in the first object, the determination method comprising:

[0017] Obtain characteristic information of the charging cable, support member, and conductor member;

[0018] Obtaining the rotation angle of the wire guide and the setting information of the connection hole according to the characteristic information;

[0019] The length information of the charging cable is determined according to the characteristic information, the rotation angle, and the setting information.

[0020] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0021] 1. This application provides a wire guide that is connected to a connecting section. After the user completes charging, the wire guide is rotated relative to the support member to extend the length of the connecting section to store the charging cable, preventing the charging port from shifting due to long-term placement in the vehicle. By utilizing the wire guide to rotate relative to the support member to extend the length of the connecting section, the pulling force on the charging cable is effectively reduced, making the charging port storage process smoother and preventing damage to vehicle components caused by excessive force during storage. The provision of a receiving hole can limit the displacement of the charging cable during the wire guide's rotation and guide the charging cable to extend stably through the connecting hole, making the storage and release of the charging cable smoother. By configuring the wire guide to rotate and extend the length of the connecting section, in the initial state, the length of the connecting section can be extended by either forward or reverse rotation. The user can freely select the direction of rotation of the wire guide to store the charging cable based on the vehicle's interior space layout, the location of the charging device, or personal operating habits, and can also freely select the storage and release length of the charging cable.

[0022] 2. As a preferred embodiment of the present application, the wire guide is provided to include an arc-shaped guide member and an annular guide sleeve rotatably provided on the guide member, and the annular guide sleeve is connected to the connecting section. In the process of the wire guide rotating to lengthen the connecting section, the annular guide sleeve contacts the connecting section and drives the connecting section to lengthen while being able to rotate, thereby reducing the friction between the connecting section and the annular guide sleeve and the wear on the connecting section, and optimizing the process of the wire guide rotating relative to the support member to lengthen the connecting section.

[0023] 3. As a preferred embodiment of the present application, by providing a connecting section and a curved section, the connection hole extends along a predetermined direction, providing space for the connecting section and the curved section, optimizing the bending angle of the curved section, and preventing the curved section from bending excessively. By setting the axis of the guide member to extend along a predetermined direction, the two transition sections of the connecting section are prevented from becoming tangled when the charging port is accommodated, thereby improving the smoothness of the charging cable storage.

[0024] 4. As a preferred embodiment of the present application, by setting the length of the connecting hole to be greater than the sum of the axial thickness of the wire member and the diameter of the two connecting segments, the movable range of the connecting segment in the preset direction is expanded to prevent the connecting hole from being stuck due to being too tight. In the process of lengthening the length of the connecting segment, the connecting hole can allow the connecting segment to swing slightly within a certain range, thereby reducing the contact area and friction loss with the connecting hole, making the movement of the connecting segment smoother.

[0025] 5. As a preferred embodiment of the present application, a rotating member is rotatably arranged on a fixed seat, and a wire member is arranged on the rotating member. The rotating member provides a stable support for the wire member, improves the smoothness of the rotation of the wire member, ensures a smooth rotation process, and the user can quickly realize the rotation action through the rotating member to complete the storage or cooperate with the release, which is convenient for the user to operate.

[0026] Furthermore, by providing multiple connection holes and multiple wire guides, the length of the charging cable that can be accommodated by the on-board charger can be adjusted according to the number of connection holes and wire guides provided, thereby improving the applicability of the on-board charger. By providing two guide members spaced relative to each other along the axis of the support member, the guide members constrain the displacement of the charging cable during the storage and release process, so that the charging cable is stored and released along the axis of the support member, preventing the charging cable from swinging under force in the accommodating hole, thereby affecting the storage and release of the charging cable. By providing a guide member that can be rotatably arranged on the support member, and the guide member is provided with a guide groove that cooperates with the charging cable, the guiding accuracy of the guide member is further improved. At the same time, during the storage or release of the charging cable, the guide member can rotate due to the friction of the charging cable, thereby reducing the friction between the guide member and the charging cable.

[0027] Furthermore, by setting the hole wall located in front along the first direction to be inclined toward the first direction, when the rotating member rotates to lengthen the connecting section, the hole wall inclined toward the first direction reduces the friction and jamming between the wire and the hole wall. When the charging cable is released, the rotating member rotates in the opposite direction until it reaches the initial position, thereby releasing the charging cable. Continuing to rotate in the opposite direction can also achieve the storage of the charging cable. The hole wall inclined in the opposite direction toward the first direction can reduce the friction and jamming between the charging cable and the hole wall when the charging cable is stored in the opposite direction.

[0028] 6. As a preferred embodiment of the present application, a protective member is provided, which extends in a preset direction to form a protective cavity, so that the rotating member, wire member, and support member are all located within the protective cavity. This prevents the on-board charger from being impacted during use, which could damage the rotating member, wire member, and support member, thereby improving the durability and safety of the on-board charger. The rigid structure of the protective cavity can absorb vibration energy during vehicle operation and reduce the rigid impact between the rotating member and the fixed seat. By providing a toggle member extending out of the protective cavity, the user can directly control the rotation of the rotating member through the toggle member without opening the protective structure, thereby achieving the retraction and extension of the charging cable and improving the convenience of use.

[0029] Furthermore, by providing a first protective cover on the end of the protective member facing away from the mounting base, the first protective cover and the protective member form a closed structure, effectively preventing dust, liquids, and other external contaminants from entering the protective cavity, protecting the rotating parts, wires, and other components from corrosion by contaminants in the vehicle environment, and extending the service life of the on-board charger. The toggle member is concealed within the protective cavity under the support of the first protective cover and is extended only when the first protective cover is opened to operate it, preventing accidental wear or damage to the toggle member when not in operation.

[0030] 7. This application also discloses a method for determining the length of a charging cable. The method determines the length of the charging cable based on characteristic information, rotation angle, and setting information, so that the on-board charger can accurately store the charging cable, avoid the charging cable being too long to be stored, and optimize the user experience of the on-board charger.

[0049] In order to more clearly illustrate the overall concept of the present application, a detailed description is given below in an illustrative manner in conjunction with the accompanying drawings.

[0050] The following description sets forth many specific details to facilitate a thorough understanding of the present application. However, the present application may also be implemented in other ways than those described herein, and therefore, the scope of protection of the present application is not limited by the specific embodiments disclosed below.

They are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present application.

[0052] like Figure 1 、 Figure 5 、 Figure 6As shown, a vehicle charger includes an electrical connector 1 and a charging interface 2. The vehicle charger also includes a support member 3 connected to the electrical connector 1. The support member 3 is provided with a receiving hole 31. The receiving hole 31 extends along a preset direction. One end of the charging cable 4 is connected to the electrical connector 1, and the other end passes through the receiving hole 31 and is connected to the charging interface 2. The support member 3 is provided with at least one connecting hole 32. The vehicle charger also includes a wire member 5 arranged corresponding to the connecting hole 32. The wire member 5 can rotate relative to the support member 3. The charging cable 4 includes an arc-shaped connecting section 41 extending out of the connecting hole 32. The wire member 5 is hooked with the connecting section 41. The wire member 5 rotates relative to the support member 3 to extend the length of the connecting section 41 to accommodate the charging cable 4.

[0053] The present application provides a wire guide 5, which is connected to a connecting section 41. After the user completes charging, the charging cable 4 is stored by rotating the wire guide 5 relative to the support member 3 to extend the length of the connecting section 41, thereby preventing the charging interface 2 from shifting due to being placed in the vehicle for a long time. By utilizing the wire guide 5 to rotate and extend the length of the connecting section 41 relative to the support member 3, the pulling force on the charging cable 4 is effectively reduced, making the storage process of the charging interface 2 smooth, and avoiding damage to the components in the vehicle caused by excessive force during the storage process of the charging interface 2. By providing a receiving hole 31, the receiving hole 31 can limit the displacement of the charging cable 4 during the rotation of the wire guide 5, and at the same time can guide the charging cable 4 to stably extend out of the connecting hole 32, making the storage and release of the charging cable 4 smoother. By setting the length of the wire guide 5 to be extended by rotating the connecting section 41, in the initial state, the length of the connecting section 41 can be extended by either forward rotation or reverse rotation. The user can freely choose the rotation direction of the wire guide 5 to store the charging cable 4 according to the space layout in the vehicle, the location of the charging device or personal operating habits, and can also freely choose the storage and release length of the charging cable.

[0054] In the present application, the support member 3 is cylindrical, and the preset direction is its axial direction. Those skilled in the art will appreciate that the preset direction may also be the axial direction of the vehicle charger. The support member 3 may also be set to be conical or elliptical, etc., which is not limited in the present application.

[0055] In the present application, the arrangement of the wire guide 5 corresponding to the connection hole 32 can be any one of the following embodiments:

[0056] Implementation method 1: Figure 1 、 Figure 5 As shown, each connection hole 32 corresponds to a corresponding wire guide 5. The connection hole 32 extends in a predetermined direction and has an axis perpendicular to the predetermined direction. The wire guide 5 is arranged in an arc shape, with a central plane perpendicular to the predetermined direction. The extension of the axis of the connection hole 32 perpendicular to the predetermined direction lies within the central plane. This further optimizes the force applied to the charging cable 4, prevents tangling of the connecting section 41, and optimizes the process of storing and releasing the charging cable 4.

[0057] Embodiment 2: This embodiment 2 is not shown in the figure. One wire guide is provided for each connection hole. The connection hole extends along a preset direction and has an axis perpendicular to the preset direction. The wire guide is arranged in an arc shape. The extension line of the axis of the connection hole perpendicular to the preset direction is provided with an angle α with the center plane, and α is an acute angle.

[0058] In the present application, the shape of the connection hole 32 is not limited. The connection hole 32 can be set to a circular hole, a square hole, an elliptical hole or a trapezoidal hole, etc., and the wire member 5 can also be set to a ring shape, etc.

[0059] In the present application, the arrangement of the wire guide 5 can be any one of the following embodiments:

[0060] Implementation method three: Figure 1 、 Figure 2 As shown, the thread guide 5 includes an annular guide member 51 and an annular guide sleeve 52 rotatably disposed on the guide member 51 , and the annular guide sleeve 52 is hooked with the connecting section 41 .

[0061] By providing the guide wire 5 with an arc-shaped guide member 51 and an annular guide sleeve 52 rotatably disposed on the guide member 51, and hooking the annular guide sleeve 52 with the connecting section 41, when the guide wire 5 rotates to extend the length of the connecting section 41, the annular guide sleeve 52 contacts the connecting section 41, driving the connecting section 41 to extend while being able to rotate, thereby reducing friction between the connecting section 41 and the annular guide sleeve 52 and wear on the connecting section 41, thereby optimizing the process of the guide wire 5 rotating relative to the support member 3 to extend the length of the connecting section 41. It will be clear to those skilled in the art that by smoothing the surface of the guide member 51, the use of the annular guide sleeve 52 can be reduced, and the guide member 51 can be used to hook the connecting section 41.

[0062] Embodiment 4: This embodiment 4 is not shown in the figure, and the wire guide can be extended and retracted along the radial direction of the support member.

[0063] As a preferred embodiment 1 under the third embodiment: Figure 1 As shown, the connection hole 32 extends along a preset direction, the connection section 41 includes two transition sections 411 arranged opposite to each other along the preset direction and a curved section 412 connecting the two transition sections 411, and the axis of the guide 51 extends along the preset direction. By providing the connection section 41 and the curved section 412, the connection hole 32 extends along the preset direction, providing accommodation space for the connection section 41 and the curved section 412, and optimizing the bending angle of the curved section 412 to prevent the curved section 412 from bending excessively. By providing the axis of the guide 51 to extend along the preset direction, the two transition sections 411 are prevented from becoming tangled when the connection section 41 receives the charging interface 2, thereby improving the smoothness of receiving the charging cable 4.

[0064] As a preferred specific example 1 under embodiment 1: the length of the connection hole 32 is greater than the sum of the axial thickness of the wire guide 5 and the diameters of the two connecting segments 41, and the width of the connection hole 32 is greater than the diameter of the charging cable 4. Preferably, the sum of the axial thickness of the wire guide 5 and the diameters of the two connecting segments 41 is d1, the length of the connection hole 32 is d2, and the ratio of d1 to d2 is l, with l being in the range of 1.2 ≤ l ≤ 1.7.

[0065] By setting the length of the connection hole 32 to be greater than the sum of the axial thickness of the wire guide 5 and the diameter of the two connecting segments 41, the movable range of the connecting segment 41 in the preset direction is expanded, preventing the connection hole 32 from being too tight and causing it to become stuck. During the process of lengthening the length of the connecting segment 41, the connection hole 32 can allow the connecting segment to slightly swing within a certain range, thereby reducing the contact area and friction loss with the connection hole 32, and making the movement of the connecting segment 41 smoother. By setting the value range of l to: 1.2≤l≤1.7, the smooth movement of the connecting segment 41 is guaranteed, and the connection hole 32 can also be used to limit the position, preventing the connecting segment 41 from irregular movement after being subjected to force.

[0066] In the present application, the rotation arrangement of the wire guide 5 relative to the support member 3 can be any one of the following embodiments:

[0067] Implementation method five: Figure 1 、 Figure 5 As shown, the vehicle charger also includes a fixed seat 6 connected to the power interface and a rotating member 7 arranged on the fixed seat 6, the support member 3 is arranged on the fixed seat 6, the accommodating hole 31 extends to the fixed seat 6, the rotating member 7 rotates around the axis of the support member 3, and the wire member 5 is arranged on the rotating member 7. In the fifth embodiment, the rotating member 7 includes a base rotatably arranged on the fixed seat 6 and a vertical plate extending from the base in a preset direction, and the wire member 5 is arranged on the vertical plate. In the fifth embodiment, for the rotation setting of the base, the base can be connected to the fixed seat 6 through a bearing, or the base can be provided with a guide groove, and the fixed seat 6 can be provided with a guide protrusion that cooperates with the guide groove, etc., which is not limited in this application. By setting the rotating member 7 to be rotatably arranged on the fixed seat 6, the wire member 5 is arranged on the rotating member 7, and the rotating member 7 provides a stable support for the wire member 5, thereby improving the smoothness of the rotation of the wire member 5 and ensuring a smooth and smooth rotation process. The user can quickly realize the rotation action through the rotating member 7 to complete the storage or the release, which is convenient for the user to operate.

[0068] Embodiment 6: This embodiment 6 is not shown in the figure. The vehicle charger further includes a fixing base connected to the power connection interface. The support member is rotatably disposed on the fixing base, and the support member rotates about its own axis.

[0069] As a preferred embodiment 2 under the fifth embodiment: Figure 1 、 Figure 5As shown, along the preset direction, the support member 3 is provided with a plurality of connection holes 32, the rotating member 7 is provided with a plurality of wire members 5, and the support member 3 is provided with two guide members 33 at one end away from the fixed seat 6. The two guide members 33 are arranged relative to each other along the axis of the support member 3. The guide member 33 can be rotatably arranged on the support member 3, and the guide member 33 is provided with a guide groove that cooperates with the charging cable 4 (not shown in the drawings).

[0070] By providing multiple connection holes 32 and multiple wire guides 5, the length of the charging cable 4 that can be accommodated by the on-board charger can be adjusted according to the number of connection holes 32 and wire guides 5 provided, thereby improving the applicability of the on-board charger. By providing two guide members 33 spaced relative to each other along the axis of the support member 3, the guide members 33 constrain the displacement of the charging cable 4 during the storage and release process, allowing the charging cable 4 to be stored and released along the axis of the support member 3, preventing the charging cable 4 from swinging under force within the accommodating hole 31, which would affect the storage and release of the charging cable 4. By providing the guide member 33 so that it can be rotatably mounted on the support member 3 and provided with a guide groove that cooperates with the charging cable 4, the guiding accuracy of the guide member 33 is further improved. At the same time, during the storage or release of the charging cable 4, the guide member 33 is able to rotate due to friction from the charging cable 4, reducing the friction between the guide member 33 and the charging cable 4.

[0071] In embodiment 2, the adjustment setting of the wire guide can be any one of the following specific examples:

[0072] Specific Example 2: This specific example 2 is not shown in the figure. A plurality of wire guides are movably mounted on a rotating member. Along a preset direction, the distance between the axes of the plurality of wire guides and the axis of the support member is gradually reduced. The wire guide includes an arcuate guide member and a movable member movably mounted on the rotating member. The rotating member is provided with a guide hole for mating with the movable member. The movable member includes a mating section threadedly connected to the guide hole and an operating section that at least partially extends out of the guide hole. The operating section is rotated to adjust the distance between the axis of the wire guide and the axis of the support member.

[0073] Specific Example 3: This specific example 3 is not shown in the figure. The wire guide is configured as a ring-shaped lock buckle. The wire guide can be opened and closed. On the one hand, it is convenient for the wire guide to be connected to the connecting section. On the other hand, by opening the wire guide, the wire guide can be partially disconnected from the charging cable to adjust the extended length of the charging cable. Preferably, the rotating member has a mounting hole corresponding to the wire guide. The vehicle charger has an operating member in the mounting hole that is connected to the wire guide and can drive the wire guide to open and close. The operating member is at least partially exposed in the mounting hole for user operation.

[0074] As a preferred specific example 4 under embodiment 2, Figure 1As shown, the user stores the charging cable 4 by operating the rotating member 7. In order to avoid the stacking of the charging cable 4 after one rotation, multiple connection holes 32 are provided, and multiple wire guides 5 reduce the required rotation angle of the rotating member 7. Preferably, the rotation angle of the rotating member 7 is set to β, and β satisfies: 15°≤β≤145°. By setting β, the stacking of the charging cable 4 during the storage process is avoided, the extension of the charging cable 4 is facilitated, and the use process of the vehicle charger is optimized. To release the charging cable 4, the charging cable 4 is extended by pulling the charging cable 4 or by operating the rotating member 7 while pulling the charging cable 4. It is clear to those skilled in the art that the rotating member 7 can also be set to rotate eccentrically around the support member 3, which can also achieve the purpose of lengthening the connecting section 41 to store the charging cable 4.

[0075] In embodiment 2, the arrangement of the connection hole 32 can be any one of the following specific examples:

[0076] Specific example 5: such as Figure 6 As shown, the connection hole 32 includes two hole walls arranged opposite to each other along the circumference of the support member 3. The rotating member 7 rotates along the first direction to extend the connecting section 41. The hole wall located in the front along the first direction is tilted toward the first direction, and the hole wall located in the rear is tilted in the opposite direction of the first direction. Preferably, the connection hole 32 also includes hole walls arranged opposite to each other along a preset direction, and the hole walls arranged opposite to each other along the preset direction are tilted. Furthermore, the connection hole 32 also includes side walls arranged opposite to each other along the preset direction, and the side walls are tilted. At the same time, the surface of the support member 3 and the hole walls and side walls of the connection hole 32 are all smoothed, and the side walls and hole wall edges are all provided with rounded corners. It is clear to those skilled in the art that the first direction can be clockwise or counterclockwise.

[0077] By setting the hole wall located in front along the first direction to be inclined toward the first direction, when the rotating member 7 rotates to elongate the connecting section 41, the hole wall inclined toward the first direction reduces the friction and jamming between the wire and the hole wall. When the charging cable 4 is released, the rotating member 7 rotates in the opposite direction until it reaches the initial position, thereby releasing the charging cable 4. Continuing to rotate in the opposite direction can also achieve the storage of the charging cable 4. The hole wall inclined in the opposite direction toward the first direction can reduce the friction and jamming between the charging cable 4 and the hole wall when the charging cable 4 is stored in the opposite direction.

[0078] Specific example 6: This specific example 6 is not shown in the figure, and the edges of the connection holes are provided with rounded corners or chamfers.

[0079] In the present application, the rotation setting of the operating guide wire 5 can be any one of the following embodiments:

[0080] Implementation method seven: Figure 1 、 Figure 3 、 Figure 4 、 Figure 5As shown, the vehicle charger also includes a fixing seat 6 connected to the power connection interface and a protective member 8 arranged along the circumference of the fixing seat 6. The protective member 8 extends along a preset direction to form a protective cavity 81. The vehicle charger also includes a rotating member 7 arranged on the fixing seat 6 and a toggle member 71 arranged on the rotating member 7. The rotating member 7 rotates around the axis of the support member 3. The wire member 5 is arranged on the rotating member 7. The toggle member 71 can extend out of the protective cavity 81.

[0081] By providing a protective member 8 that extends in a predetermined direction to form a protective cavity 81, the rotating member 7, the wire member 5, and the support member 3 are all located within the protective cavity 81. This prevents impacts on the on-board charger during use that could damage the rotating member 7, the wire member 5, and the support member 3, thereby improving the durability and safety of the on-board charger. The rigid structure of the protective cavity 81 absorbs vibration energy during vehicle operation and reduces the rigid impact between the rotating member 7 and the fixing seat 6. By providing a toggle member 71 extending out of the protective cavity 81, the user can directly control the rotation of the rotating member 7 through the toggle member 71 without opening the protective structure, thereby retracting and extending the charging cable 4 and improving user convenience.

[0082] Embodiment 8: The vehicle charger further includes a fixing base connected to the power connection interface and a protective member arranged along the circumference of the fixing base. The protective member extends along a preset direction to form a protective cavity. The protective member is rotatably arranged on the fixing base, and the rotating member is arranged on the protective member. The user drives the rotating member to rotate by twisting the protective member.

[0083] In a preferred embodiment 3 under the seventh embodiment, as Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 As shown, the rotating member 7 is provided with a mounting hole 72, and the toggle member 71 is movably arranged in the mounting hole 72. The vehicle charger also includes a first protective cover 9 detachably arranged at the end of the protective member 8 away from the fixing seat 6. The toggle member 71 is connected to the rotating member 7 through an elastic reset member 73. The first protective cover 9 can push against the toggle member 71 so that the toggle member 71 is located in the protective cavity 81.

[0084] By installing a first protective cover 9 on the end of the protective member 8 facing away from the mounting base 6, the first protective cover 9 and the protective member 8 form a closed structure, effectively preventing dust, liquids, and other external contaminants from entering the protective cavity 81. This protects the rotating member 7, the wiring harness 5, and other components from being corroded by contaminants in the vehicle environment, thereby extending the service life of the on-board charger. The toggle member 71 is concealed within the protective cavity 81 under the support of the first protective cover 9 and is extended only when the first protective cover 9 is opened to operate it. This prevents accidental wear or damage to the toggle member 71 when not in operation.

[0085] It is clear to those skilled in the art that the first protective cover 9 can be detachably arranged on the protective part 8 in such a way that the first protective cover 9 is sleeved on the protective part 8, or the surface of the protective part 8 is provided with an external thread, and the first protective cover 9 is threadedly connected to the protective part 8, or the first protective cover 9 is provided with an extension section that cooperates with the protective cavity 81, the protective cavity 81 is provided with an internal thread, the extension section is threadedly connected to the protective cavity 81, and the extension section abuts against the toggle member 71.

[0086] As a preferred specific example 7 under embodiment 3, the vehicle charger further includes a second protective cover 10 detachable from the fixing base 6 , and a positioning member 101 cooperating with the electrical connector 1 is provided in the second protective cover.
