Description

Technical Field

[0001] This application relates to the field of charging technology, and particularly to a charger and a watch. Background Art

[0002] As users' requirements for watch chargers are getting higher and higher, in order to facilitate portability, in related technologies, there have emerged small-sized bean-shaped chargers. The charger generally includes a charging structure and a charging cable. The charging structure is used for electrically connecting to the electrical appliance, and the charging cable is used for electrically connecting the charging structure to the power source to charge the battery in the electrical appliance through the power source.

[0003] However, in related technologies, the angle formed by the charging cable and the electrical appliance during charging is usually fixed. When connecting the charging cable to the power source, the charging cable is prone to large bends, resulting in the charging cable being easily broken due to bending during long-term use. Summary of the Invention

[0004] This application provides a charger and a watch, which can change the routing direction of the second end of the charging cable according to requirements, preventing problems such as breakage or poor contact of the charging cable caused by large bends of the charging cable.

[0005] In a first aspect, this application provides a charger, which includes:

[0006] A base;

[0007] A charging head rotatably arranged at the top of the base. The charging head is provided with a charging contact part for charging the electrical appliance, and the charging contact part is located on the side of the charging head away from the base;

[0008] A rotating assembly, which includes a connecting shaft. One end of the connecting shaft is connected to the charging head, and the other end is inserted into the base. The base is rotatably connected to the charging head through the connecting shaft;

[0009] A charging cable connected to the base and electrically connected to the charging contact part;

[0010] Wherein, the base includes a peripheral side plate arranged around the connecting shaft. The peripheral side plate is provided with a first routing hole, and the connecting shaft is provided with a second routing hole penetrating through both ends of the connecting shaft. The second routing hole includes a first port located inside the base and a second port located inside the charging head. The first end of the charging cable sequentially passes through the first routing hole, the first port, and the second port, and is electrically connected to the charging component. The second end of the charging cable is located outside the housing and is used for electrically connecting to the power supply. When the base rotates relative to the charging head around the connecting shaft, the second end is driven to rotate around the connecting shaft.

[0011] In some embodiments of the present application, the included angle between the direction of the charging contact portion towards the electrical appliance and the charging line is 60° to 120°.

[0012] In some embodiments of the present application, the rotating assembly further includes a limiting structure, and the limiting structure includes: a first limiting member connected to the charging head; a second limiting member connected to the base, and the second limiting member and the first limiting member are arranged circumferentially along the connecting shaft. When the base rotates relative to the charging head in a first rotation direction until the second limiting member abuts against the first limiting member, the first limiting member prevents the base from rotating in the first rotation direction; when the base rotates relative to the charging head in a second rotation direction until the second limiting member abuts against the first limiting member, the first limiting member prevents the base from rotating in the second rotation direction, and the second rotation direction is opposite to the first rotation direction.

[0013] In some embodiments of the present application, a through hole for the connecting shaft to pass through is provided on one side of the base facing the charging head. The first limiting member is arranged on the outer periphery of the connecting shaft and is fixedly connected to the charging head through the connecting shaft, and the second limiting member is arranged on the inner side wall of the through hole.

[0014] In some embodiments of the present application, a first position is provided on the rotatable trajectory of the first wire routing hole. The rotating assembly further includes a locking structure, and the locking structure includes: a first locking member connected to the charging head, and a second locking member connected to the base. When the first wire routing hole is at the first position, the second locking member is locked with the first locking member to realize the locking of the base and the charging head; when the first wire routing hole is at the first position and the base rotates relative to the charging head under an external force, the second locking member is driven to unlock from the first locking member to realize the unlocking of the base and the charging head.

[0015] In some embodiments of the present application, a second position is further provided on the rotatable trajectory of the first wire routing hole. The orientation of the first wire routing hole when it is at the first position is different from the orientation when it is at the second position. When the first wire routing hole is at the second position, the second locking member is locked with the first locking member to realize the locking of the base and the charging head; when the first wire routing hole is at the second position and the base rotates relative to the charging head under an external force, the second locking member is driven to unlock from the first locking member.

[0016] In some embodiments of the present application, the first wire hole rotates 90 degrees from the first position in the first rotation direction to the second position.

[0017] In some embodiments of the present application, both the first locking member and the second locking member are disposed within the base. The first locking member is sleeved on the connecting shaft and is fixedly connected to the charging head through the connecting shaft; the second locking member is sleeved on the connecting shaft and is rotatably connected to the connecting shaft.

[0018] In some embodiments of the present application, the first locking member and the second locking member are arranged along the axial direction of the connecting shaft. One of a clamping block and a clamping groove is provided on a side of the first locking member facing the second locking member, and the other of the clamping block and the clamping groove is provided on a side of the second locking member facing the first locking member; wherein, when the first wire hole is in the first position, the clamping block is clamped with the clamping groove to realize the locking of the base and the charging head; when the first wire hole is in the first position and the base rotates relative to the charging head under an external force, the clamping block and the clamping groove are driven to separate to realize the unlocking of the base and the charging head.

[0019] In some embodiments of the present application, the clamping block extends along the circumferential direction of the connecting shaft. The outer surface of the clamping block includes a top side surface, a first end surface and a second end surface. The top side surface is located on a side of the clamping block facing the first locking member. The first end surface and the second end surface are arranged along the circumferential direction of the connecting shaft and are respectively located at both ends of the top side surface. The first end surface extends obliquely away from the top side surface, and the second end surface extends obliquely away from the top side surface; the clamping groove extends along the circumferential direction of the connecting shaft. The groove wall surface of the clamping groove includes a first groove wall surface and a second groove wall surface. When the first wire hole is in the first position, the first groove wall surface is attached to the first end surface, and the second groove wall surface is attached to the second end surface.

[0020] In some embodiments of the present application, a plurality of the clamping grooves and a plurality of the clamping blocks are provided. The plurality of clamping grooves are arranged at intervals along the circumferential direction of the connecting shaft, and the plurality of clamping blocks are arranged at intervals along the circumferential direction of the connecting shaft.

[0021] In some embodiments of the present application, the rotating assembly further includes: a reset member sleeved on the connecting shaft. The reset member is connected to the base and the charging head, and the reset member is used to provide an elastic force for the second locking member to rotate in a direction close to the first locking member to lock with the first locking member.

[0022] In some embodiments of the present application, the charger further includes: a charging circuit board disposed in the charging head and electrically connected to the first end portion and the charging contact portion, and the first end portion is electrically connected to the charging contact portion through the charging circuit board.

[0023] In some embodiments of the present application, the charging contact portion includes: a charging sheet group including a first charging sheet and a second charging sheet arranged along a first direction, the first direction being perpendicular to the direction in which the charging contact portion faces the electrical appliance; a data conduction group located between the first charging sheet and the second charging sheet, the data conduction group including a plurality of conductive pins arranged along a second direction, the second direction being perpendicular to the first direction and the direction in which the charging contact portion faces the electrical appliance.

[0024] In some embodiments of the present application, the charging head includes a first housing and a second housing that are detachably connected, and the base includes a third housing and a fourth housing that are detachably connected. The first housing, the second housing, the third housing, and the fourth housing are sequentially stacked along the direction in which the charging contact portion faces the electrical appliance.

[0025] In some embodiments of the present application, the charging cable includes a magnet for magnetically connecting with the electrical appliance.

[0026] In a second aspect, the present application further provides a watch, including a watch body and the charger as described in any one of the above embodiments. The watch body is an electrical appliance, and the charging contact portion is in contact with and electrically connected to the watch body.

[0027] The beneficial effects of the present application are as follows: When using the charger to charge the power module of the watch in scenarios such as exhibition booths, the placement position of the electrical appliance and the connection position of the second end portion to the power supply (taking a socket as an example) are usually fixed. At this time, the base can be rotated relative to the charging head according to the placement positions of the socket and the electrical appliance. When the base rotates, the inner wall of the first wire passing hole contacts the charging cable and drives the second end portion to rotate, so that the position of the second end portion can be adjusted, and the angle formed by the second end portion and the electrical appliance can be changed, making the insertion direction of the second end portion parallel to the socket, preventing the charging cable from being bent greatly, resulting in problems such as breakage or poor contact of the charging cable; in addition, by passing the first end portion of the connection cable through the connection shaft and electrically connecting it to the charging component, when the base rotates, only the contact portion between the first wire passing hole and the charging cable applies a pulling force to the connection portion between the first end portion and the charging component, which can reduce the pulling force on the connection portion between the first end portion and the charging component when rotating the base, preventing problems such as loosening of the connection portion between the first end portion and the charging component and resulting in poor contact.

[0038] To make the objectives, technical solutions and advantages of the present application more clear and understandable, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0039] The present application provides a charger and a watch to solve the problem that in the related art, the angle formed by the charging cable and the electrical appliance during charging is usually fixed. When connecting the charging cable to the power supply, the charging cable is prone to large bending, resulting in the charging cable being easily broken due to bending during long-term use.

[0040] In a first aspect, the present application provides a charger that can be applied to an electrical appliance 80 (such as Figure 7 ). Taking the watch body of the watch as an example of the electrical appliance 80, the charger can electrically connect the power module (such as a storage battery) in the watch body to a power supply (such as the power grid, a power bank, etc.) to charge the power module in the watch body.

[0041] Specifically, as Figure 1 and Figure 2 shown, the charger includes a charging cable 10, a charging head 30, and a base 40; the charging head 30 is provided with a charging contact portion 51 for charging the electrical appliance 80, and the charging contact portion 51 is used to electrically connect to the electrical appliance 80 to achieve electrical connection between the charging cable 10 and the power module in the electrical appliance 80; the charging cable 10 is connected to the base 40, the charging cable 10 is electrically connected to the charging contact portion 51, and the charging cable 10 is used to achieve electrical connection between the power supply and the charging contact portion 51, and further achieve electrical connection between the power supply and the power module in the electrical appliance 80.

[0042] Among them, the charger further includes a rotating assembly 20, and the rotating assembly 20 is disposed between the base 40 and the charging head 30 to enable the charging head 30 to rotate relative to the base 40.

[0043] It should be noted that in the present application, the charging head 30 can rotate relative to the base 40. When using the charger to charge the electrical appliance 80, the charging head 30 can be rotated according to the space where the electrical appliance 80 is located and the actual placement position to adjust the angle of the included angle formed between the charging contact portion 51 and the charging cable 10, so as to adjust the angle formed between the charging cable 10 and the electrical appliance 80 during charging, thereby preventing problems such as the charging cable 10 being broken or having poor contact due to large bending.

[0044] Specifically, the charging head 30 is rotatably arranged at the top end of the base 40, and the charging contact portion 51 is located on the side of the charging head 30 away from the base 40. When using the charger to charge the electrical appliance 80, the base 40 can be placed on a tabletop or desktop, etc., and the base 40 is used to provide support. At this time, the charging contact portion 51 is arranged upward, and the electrical appliance 80 is placed on the top end of the charging head 30 and contacts the charging contact portion 51, so that the charging of the electrical appliance 80 can be realized, making the charging of the electrical appliance 80 more convenient. Among them, the charging head 30 can be strip-shaped, and the base 40 can be cylindrical.

[0045] Continue to refer to Figure 1 and Figure 2 As shown, the rotating assembly 20 includes a connecting shaft 60. One end of the connecting shaft 60 is connected to the charging head 30, and the other end is inserted into the base 40. The charging head 30 is rotatably connected to the base 40 through the connecting shaft 60. Among them, the base 40 includes a peripheral side plate 41 arranged around the connecting shaft 60. A first wire passing hole 411 is arranged on the peripheral side plate 41. A second wire passing hole 61 penetrating through both ends of the connecting shaft 60 is arranged on the connecting shaft 60. The second wire passing hole 61 includes a first port 611 located inside the base 40 and a second port 612 located inside the charging head 30. The first end portion 11 of the charging wire 10 sequentially passes through the first wire passing hole 411, the first port 611, and the second port 612, and is electrically connected to the charging contact portion 51. The second end portion 12 of the charging wire 10 is located outside the base 40 and is used for electrical connection with the power supply. When the base 40 rotates relative to the charging head 30 around the connecting shaft 60, the second end portion 12 is driven to rotate around the connecting shaft 60.

[0046] It can be understood that the first end portion 11 of the charging wire 10 extends into the charging head 30 and is electrically connected to the charging contact portion 51. The second end portion 12 of the charging wire 10 is located outside the base 40. The second end portion 12 of the charging wire 10 is used for electrical connection with the power supply. The second end portion 12 can have a connector of the type such as a charging plug or a USB interface. α is the included angle formed by the direction K in which the charging contact portion 51 faces the electrical appliance 80 and the second end portion 12 of the charging wire 10. At this time, α is 90 degrees or close to 90 degrees. When using the charger to charge the power module of the watch in scenarios such as exhibition booths, the placement position of the electrical appliance 80 and the connection position of the second end portion 12 with the power supply (taking the socket as an example) are usually fixed. At this time, according to the placement positions of the socket and the electrical appliance 80, the base 40 can be rotated relative to the charging head 30. When the base 40 rotates, the first wire passing hole 411 contacts the charging wire 10 and then drives the second end portion 12 to rotate, so that the position of the second end portion 12 can be adjusted, and the angle formed by the second end portion 12 and the electrical appliance 80 can be changed, so that the insertion direction of the second end portion 12 and the socket is parallel to the second end portion 12, preventing problems such as breakage or poor contact of the charging wire 10 caused by large bending of the charging wire 10.

[0047] It should also be noted that in the present application, by passing the first end 11 of the connection line through the connection shaft 60 to be electrically connected to the charging contact portion 51, when the base 40 rotates, a pulling force is applied to the connection between the first end 11 and the charging contact portion 51 only at the contact point between the first wire passing hole 411 and the charging wire 10. This can reduce the pulling force on the connection between the first end 11 and the charging contact portion 51 when the base 40 rotates, and prevent problems such as loosening at the connection between the first end 11 and the charging contact portion 51, which may cause poor contact.

[0048] In some embodiments, the angle α between the direction K in which the charging contact portion 51 faces the electrical appliance 80 and the charging wire 10 is 60° to 120°. It should be noted that the direction K in which the charging contact portion 51 faces the electrical appliance 80 is the orientation of the charging contact portion 51 when it charges the electrical appliance 80; α can be 60 degrees, 75 degrees, 90 degrees, 110 degrees, 120 degrees, or other angles.

[0049] In some embodiments, the charging head 30 and the base 40 can be stacked in the direction K in which the charging contact portion 51 faces the electrical appliance 80, and the axial direction of the connection shaft 60 is parallel to the direction K in which the charging contact portion 51 faces the electrical appliance 80, so as to prevent the rotation of the base 40 around the axial direction of the connection shaft 60 during the charging process from affecting the contact between the charging contact portion 51 and the electrical appliance 80 when the wiring of the second end 12 is changed.

[0050] Specifically, the charger further includes a charging circuit board 52, which is disposed in the charging head 30 and is electrically connected to the first end 11 and the charging contact portion 51. The first end 11 is electrically connected to the charging contact portion 51 through the charging circuit board 52. The charging circuit board 52 can perform functions such as voltage stabilization, voltage conversion, circuit protection, and control. By disposing the charging circuit board 52 in the charging head 30, the circuit board does not need to rotate with the base 40 when the base 40 rotates, so that the charging contact portion 51 and the charging circuit board 52 do not need to rotate with the base 40 either, thereby making the connection between the charging contact portion 51 and the charging circuit board 52 more stable. Among them, the charging circuit board 52 can be a single-sided board, a double-sided board, or a multi-layer board. The present application does not make specific limitations on the type, model, size, etc. of the circuit board.

[0051] Such as Figures 2 to 4As shown, in some embodiments of the present application, there is a first position on the rotatable trajectory of the first wire hole 411. The rotating assembly 20 further includes a locking structure, which includes a first locking member 71 and a second locking member 72. The first locking member 71 is connected to the charging head 30; the second locking member 72 is connected to the base 40. When the first wire hole 411 is in the first position, the second locking member 72 is locked with the first locking member 71 to achieve the locking of the base 40 and the charging head 30; when the first wire hole 411 is in the first position and the base 40 rotates relative to the charging head 30 under an external force, it drives the second locking member 72 to unlock from the first locking member 71 to achieve the unlocking of the base 40 and the charging head 30.

[0052] It can be understood that the specific position of the first position can be selected according to actual needs. The position and wire routing direction of the second end 12 are determined by the first wire hole 411. Taking Figure 3 the shown perspective as an example, when the second end 12 extends in a straight line, the wire routing direction of the first wire hole 411 is usually parallel or substantially parallel to the orientation of the first wire hole 411. When the first wire hole 411 is in the first position, the locking of the base 40 and the charging head 30 can be achieved through the locking of the first locking member 71 and the second locking member 72, so that the base 40 and the charging head 30 are fixed, and then the second end 12 can stay stably in this wire routing direction at this time, preventing the base 40 from driving the second end 12 to rotate due to factors such as vibration or accidental touch, and playing the role of rotating in place; when it is necessary to adjust the wire routing direction of the second end 12, the user can rotate the base 40 so that the base 40 rotates relative to the charging head 30 under an external force, driving the second locking member 72 to unlock from the first locking member 71.

[0053] Further, there is also a second position on the rotatable trajectory of the first wire hole 411. The orientation of the first wire hole 411 when it is in the first position is different from the orientation of the first wire hole 411 when it is in the second position. When the first wire hole 411 is in the second position, the second locking member 72 is locked with the first locking member 71 to achieve the locking of the base 40 and the charging head 30; when the first wire hole 411 is in the second position and the base 40 rotates relative to the charging head 30 under an external force, it drives the second locking member 72 to unlock from the first locking member 71. It should be noted that taking Figure 1 the first wire hole 411 in the first position in Figure 5Taking the first wire hole 411 located at the second position as an example, when the first wire hole 411 is located at the first position, the wire routing direction of the second end 12 is different from that when the first wire hole 411 is located at the second position. When the first wire hole 411 is located at the first position and the second position, fixation can be achieved through the locking of the first locking member 71 and the second locking member 72, so that the second end 12 can stay stably in multiple wire routing directions, preventing the base 40 from driving the second end 12 to rotate due to factors such as vibration or accidental touch.

[0054] Furthermore, the first wire hole 411 rotates 90 degrees from the first position along the first rotation direction R1 to the second position. When the first wire hole 411 rotates from the first position to the second position, the wire routing direction of the second end 12 changes greatly (the change angle is 90 degrees or close to 90 degrees), which can meet the requirements of more scenarios; among them, the first rotation direction R1 can be the clockwise direction or the counterclockwise direction.

[0055] It should also be noted that the first wire hole 411 can also be locked by the first locking member 71 and the second locking member 72 in more positions. For example, the first wire hole 411 can also have a third position. The orientation of the first wire hole 411 at the third position is different from that at the second position and the first position. When the first wire hole 411 is located at the third position, the second locking member 72 is locked with the first locking member 71 to achieve the locking of the base 40 and the charger head 30; when the first wire hole 411 is located at the third position and the base 40 rotates relative to the charger head 30 under the action of an external force, the second locking member 72 is driven to unlock from the first locking member 71. Among them, the first position can be that the orientation of the first wire hole 411 can be the 12 o'clock direction, the second position can be that the orientation of the first wire hole 411 can be the 3 o'clock direction, and the third position can be that the orientation of the first wire hole 411 can be the 9 o'clock direction.

[0056] In some embodiments, both the first locking member 71 and the second locking member 72 are disposed within the base 40. The first locking member 71 is sleeved on the connecting shaft 60 and is fixedly connected to the charging head 30 through the connecting shaft 60. The second locking member 72 is sleeved on the connecting shaft 60 and is rotatably connected to the connecting shaft 60. It can be understood that the connecting shaft 60 is fixed to the charging head 30 and inserted into the base 40. The connecting shaft 60 can be integrally formed with the charging head 30 or formed separately from the charging head 30 and then spliced by bonding, snap connection, threaded connection or other means. The first locking member 71 is fixed to the connecting shaft 60, thereby realizing a fixed connection with the charging head 30. The base 40 is rotatably connected to the connecting shaft 60. When the base 40 rotates around the connecting shaft 60 relative to the charging head 30 and the connecting shaft 60, the second locking member 72 is driven to rotate relative to the first locking member 71, so as to realize the locking and unlocking of the second locking member 72 and the first locking member 71, making the locking and unlocking of the second locking member 72 and the first locking member 71 more convenient.

[0057] Continue to refer to Figures 2 to 4 As shown, in some embodiments, the first locking member 71 and the second locking member 72 are arranged along the axial direction of the connecting shaft 60. One of the engaging block 73 and the engaging slot 74 is disposed on the side of the first locking member 71 facing the second locking member 72, and the other of the engaging block 73 and the engaging slot 74 is disposed on the side of the second locking member 72 facing the first locking member 71.

[0058] Among them, when the first wire hole 411 is in the first position, the engaging block 73 is engaged with the engaging slot 74 to realize the locking of the base 40 and the charging head 30. When the first wire hole 411 is in the first position and the base 40 rotates relative to the charging head 30 under an external force, the engaging block 73 is driven to separate from the engaging slot 74 to realize the unlocking of the base 40 and the charging head 30. Through the cooperation of the engaging block 73 and the engaging slot 74, the locking and unlocking of the first locking member 71 and the second locking member 72 can be realized, which can play a role of rotating in place for the user and has characteristics such as interestingness, playability, and stress relief properties, and can give the user a better experience.

[0059] Further, the clamping block 73 extends circumferentially along the connecting shaft 60. The outer surface of the clamping block 73 includes a top side surface 731, a first end surface 732, and a second end surface 733. The top side surface 731 is located on the side of the clamping block 73 facing the first locking member 71. The first end surface 732 and the second end surface 733 are arranged circumferentially along the connecting shaft 60 and are respectively located at both ends of the top side surface 731. The first end surface 732 extends obliquely away from the top side surface 731, and the second end surface 733 extends obliquely away from the top side surface 731; the slot 74 extends circumferentially along the connecting shaft 60. The slot wall surface of the slot 74 includes a first slot wall surface 741 and a second slot wall surface 742. When the first wire hole 411 is in the first position, the first slot wall surface 741 is in contact with the first end surface 732, and the second slot wall surface 742 is in contact with the second end surface 733. It should be noted that taking Figure 3 the perspective shown as an example, the inclined extension of the first end surface 732 and the second end surface 733 can play a guiding role. When the first wire hole 411 is in the first position and the base 40 is rotated clockwise, driving the second locking member 72 to rotate clockwise, the first slot wall surface 741 slides along the first end surface 732, making the separation of the clamping block 73 from the slot 74 smoother; when the base 40 is rotated counterclockwise, driving the second locking member 72 to rotate clockwise, the second slot wall surface 742 slides along the second end surface 733, making the separation of the clamping block 73 from the slot 74 smoother, so that the clamping and separation of the clamping block 73 and the slot 74 can be achieved smoothly both when the base 40 is rotated clockwise and counterclockwise, preventing jamming.

[0060] In some embodiments, a plurality of slots 74 and clamping blocks 73 are provided. The plurality of slots 74 are arranged at intervals circumferentially around the connecting shaft 60, and the plurality of clamping blocks 73 are arranged at intervals circumferentially around the connecting shaft 60, so that the base 40 can be locked and fixed to the charger head 30 at multiple positions (such as when the first wire hole 411 is in the first position, the second position, and the third position). Among them, the number of the slots 74 and the clamping blocks 73 can be 2, 3, or more.

[0061] In some embodiments, the rotating assembly 20 further includes a reset member 75. The reset member 75 is sleeved on the connecting shaft 60. The reset member 75 is connected to the base 40 and the charging head 30. The reset member 75 is configured to provide an elastic force for the second locking member 72 to rotate towards the first locking member 71 to lock with the first locking member 71. The reset member 75 can be a spring, a spring piece or an elastic block. When the second locking member 72 and the first locking member 71 are in an unlocked state, the reset member 75 is in a compressed or stretched state. The reset member 75 will provide an elastic force for the second locking member 72 to rotate towards the first locking member 71. When the user rotates the base 40 to make the second locking member 72 rotate towards the first locking member 71, the elastic force provided by the reset member 75 for the second locking member 72 can make the rotation of the base 40 smoother and lighter, which can improve the user experience.

[0062] As Figure 6 shown, in some embodiments of the present application, the rotating assembly 20 further includes a limiting structure. The limiting structure includes a first limiting member 76 and a second limiting member 77; the first limiting member 76 is connected to the charging head 30; the second limiting member 77 is connected to the base 40. The second limiting member 77 and the first limiting member 76 are arranged circumferentially along the connecting shaft 60. When the base 40 rotates relative to the charging head 30 along the first rotation direction R1 until the second limiting member 77 abuts against the first limiting member 76, the first limiting member 76 prevents the base 40 from rotating along the first rotation direction R1; when the base 40 rotates relative to the charging head 30 along the second rotation direction R2 until the second limiting member 77 abuts against the first limiting member 76, the first limiting member 76 prevents the base 40 from rotating along the second rotation direction R2. The second rotation direction R2 is opposite to the first rotation direction R1.

[0063] It can be understood that the first rotation direction R1 and the second rotation direction R2 are two opposite rotation directions. When the first rotation direction R1 is counterclockwise, the second rotation direction R2 is clockwise; when the first rotation direction R1 is clockwise, the second rotation direction R2 is counterclockwise. When the base 40 is rotated along the first rotation direction R1 by a certain angle, the second limiting member 77 will abut against the first limiting member 76, and the first limiting member 76 will prevent the base 40 from continuing to rotate along the first rotation direction R1. Similarly, when the base 40 is rotated along the second rotation direction R2 by a certain angle, the second limiting member 77 will also abut against the first limiting member 76, and the first limiting member 76 will prevent the base 40 from continuing to rotate along the second rotation direction R2, thereby preventing the part of the charging cable 10 located inside the base 40 and the charging head 30 from being wound up due to continuous rotation of the base 40 in one direction for multiple turns.

[0064] Among them, the second limiting member 77 can rotate 180 degrees by abutting against one end of the first limiting member 76 to abut against the other end of the first limiting member 76. For example, the second limiting member 77 rotates along the first rotation direction R1 to abut against one end of the first limiting member 76, and at this time, when the second limiting member 77 rotates 180 degrees along the second rotation direction R2, it abuts against the other end of the first limiting member 76.

[0065] In some embodiments, a through hole 42 for the connecting shaft 60 to pass through is provided on the side of the base 40 facing the charging head 30. The first limiting member 76 is arranged on the outer periphery of the connecting shaft 60 and is fixedly connected to the charging head 30 through the connecting shaft 60. The second limiting member 77 is arranged on the inner side wall of the through hole 42. The through hole 42 can provide an accommodation space for the first limiting member 76 and the second limiting member 77, which can reduce the overall volume of the charger and make the charger more convenient to carry.

[0066] See Figure 5 As shown, in some embodiments, the charging head 30 includes a first housing 31 and a second housing 32 that are detachably connected. The base 40 includes a third housing 43 and a fourth housing 44 that are detachably connected. The first housing 31, the second housing 32, the third housing 43, and the fourth housing 44 are stacked in sequence along the direction in which the charging contact portion 51 faces the electrical appliance 80, so that both the base 40 and the charging head 30 can be disassembled, facilitating the inspection and maintenance of the components inside the base 40 and the charging head 30.

[0067] In some embodiments, the charging contact portion 51 includes a charging sheet group 511 and a data conduction group 512; the charging sheet group 511 includes a first charging sheet 511a and a second charging sheet 511b arranged along a first direction XX, the first direction XX is perpendicular to the axial direction of the connecting shaft 60, the first charging sheet 511a and the second charging sheet 511b can be a positive charging sheet and a negative charging sheet respectively, and the first charging sheet 511a and the second charging sheet 511b are used to fit with the charging contacts on the electrical appliance 80, so as to realize the electrical connection between the power supply module of the electrical appliance 80 and the charging line 10; the data conduction group 512 is located between the first charging sheet 511a and the second charging sheet 511b, the data conduction group 512 includes a plurality of conductive pins 512a arranged along a second direction YY, the second direction YY is perpendicular to the first direction XX and the axial direction of the connecting shaft 60, and the plurality of conductive pins 512a can include positive conductive pins 512a and negative conductive pins 512a, which are used to fit with the conductive contacts on the electrical appliance 80 to realize data transmission between the power supply module and the charging line 10; in this embodiment, by arranging the first charging sheet 511a and the second charging sheet 511b along the first direction XX, and arranging the conductive pins 512a between the first charging sheet 511a and the second charging sheet 511b and along the second direction YY, the space along the first direction XX and the second direction YY on the charging head 30 can be fully utilized, the volume of the charging head 30 can be further reduced, so as to reduce the volume of the charger, and make the charger more miniaturized.

[0068] Specifically, the charging line 10 can include a positive electrical connection line, a negative electrical connection line, a positive signal transmission line and a negative signal transmission line. The positive electrical connection line, the negative electrical connection line, the positive signal transmission line and the negative signal transmission line are all welded to the charging circuit board 52 to be electrically connected to the positive charging sheet, the negative charging sheet, the positive conductive pin 512a and the negative conductive pin 512a respectively.

[0069] In some embodiments, the charging line 10 includes a magnet for magnetically connecting with the electrical appliance 80. By magnetically connecting the magnet with the electrical appliance 80, the charger is fixed on the electrical appliance 80. The magnet is arranged on the charging line 10, which can prevent the magnet from interfering with the electronic components in the first housing 31 and the second housing 32.

The watch includes a watch body and a charger as described in any one of the above embodiments. The watch body is the electrical appliance 80, and the charging contact portion 51 is in contact with and electrically connected to the electrical appliance 80.

[0071] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
