DETAILED DESCRIPTION

[0038] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not 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 charging contact part is usually fixed on the shell of the charger, so that the angle formed by the charging cord and the electric appliance during charging is usually fixed, and when the charging cord is connected with the power supply, the charging cord is prone to large bending, which causes the charging cord to be prone to breakage due to bending during long-term use.

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

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

[0042] The charger further includes a rotating assembly 20, which is arranged between the base 40 and the charging head 30 to enable the charging head 30 to rotate relative to the base 40, and the included angle a between the direction K of the charging contact part 51 towards the electric appliance 80 and the charging cord 10 is 60° to 120°. It should be noted that the direction K of the charging contact part 51 towards the electric appliance 80 is the orientation of the charging contact part 51 when charging the electric appliance 80; a can be 60 degrees, 75 degrees, 90 degrees, 110 degrees, 120 degrees or other angles.

[0043] It should be noted that in the present application, the charging head 30 can rotate relative to the base 40, and when the charger is used to charge the electrical appliance 80, the charging head 30 can be rotated according to the space and actual placement position of the electrical appliance 80 to adjust the angle of the included angle formed between the charging contact part 51 and the charging wire 10, so that the angle formed between the charging wire 10 and the electrical appliance 80 during charging can be adjusted, thereby preventing the charging wire 10 from being bent too much to cause problems such as breakage or poor contact of the charging wire 10.

[0044] In some embodiments, the charging head 30 is rotatably arranged at the top end of the base 40, and the charging contact part 51 is located on the side of the charging head 30 away from the base 40, so that when the charger is used to charge the electrical appliance 80, the base 40 can be placed on a table top or desktop, etc. The support provided by the base 40 is used at this time, and the charging contact part 51 is arranged upwardly, and the electrical appliance 80 is placed on the top end of the charging head 30 and contacts the charging contact part 51, so that the electrical appliance 80 can be placed and charged, and the charging of the electrical appliance 80 is more convenient. The charging head 30 can be in a strip shape, and the base 40 can be in a cylindrical shape.

[0045] Continuing to refer to Figure 1 and Figure 2 In some embodiments of the present application, the rotating assembly 20 includes a connecting shaft 60, one end of the connecting shaft 60 is connected with the charging head 30, and the other end is inserted into the base 40, and the charging head 30 is rotatably connected with the base 40 through the connecting shaft 60. The base 40 includes a circumferential side plate 41 arranged around the connecting shaft 60, the circumferential side plate 41 is provided with a first wire hole 411, the connecting shaft 60 is provided with a second wire hole 61 penetrating through both ends of the connecting shaft 60, the second wire hole 61 includes a first port 611 located in the base 40 and a second port 612 located in the charging head 30, the first end part 11 of the charging wire 10 passes through the first wire hole 411, the first port 611 and the second port 612 in sequence, and is electrically connected with the charging contact part 51, the second end part 12 of the charging wire 10 is located outside the base 40 and is used for electrically connecting with the power supply, and when the base 40 rotates relative to the charging head 30 around the connecting shaft 60, the second end part 12 is driven to rotate around the connecting shaft 60.

[0046] It can be understood that the first end 11 of the charging wire 10 extends into the charging head 30 and is electrically connected with the charging contact 51, the second end 12 of the charging wire 10 is located outside the base 40, the second end 12 of the charging wire 10 is used to be electrically connected with the power supply, the second end 12 can have a connector such as a charging plug or a USB interface, a is an included angle formed between the direction K of the charging contact 51 towards the electric appliance 80 and the second end 12 of the charging wire 10, and a is close to 90 degrees when a is 90 degrees. When the charger is used to charge the power module of the watch in the scene such as an exhibition stand, the placement position of the electric appliance 80 and the connection position (for example, a socket) of the second end 12 with the power supply are usually fixed, at this time, the base 40 can be rotated relative to the charging head 30 according to the placement position of the socket and the electric appliance 80, when the base 40 rotates, the first wire hole 411 contacts the charging wire 10 and drives the second end 12 to rotate, so that the position of the second end 12 can be adjusted, the angle formed between the second end 12 and the electric appliance 80 is changed, the plug-in direction of the second end 12 and the socket is parallel to the second end 12, and the problem that the charging wire 10 is bent too much to cause the charging wire 10 to break or contact poorly is prevented.

[0047] It should be further pointed out that in the present application, by passing the first end 11 of the connecting wire through the connecting shaft 60 and electrically connecting with the charging contact 51, when the base 40 rotates, only the contact between the first wire hole 411 and the charging wire 10 exerts a pulling force on the connection between the first end 11 and the charging contact 51, which can reduce the pulling force on the connection between the first end 11 and the charging contact 51 when the base 40 rotates, and prevent the connection between the first end 11 and the charging contact 51 from loosening and causing poor contact.

[0048] In some embodiments, the charging head 30 and the base 40 can be stacked in the direction K of the charging contact 51 towards the electric appliance 80, and the axis of the connecting shaft 60 is parallel to the direction K of the charging contact 51 towards the electric appliance 80, which prevents the rotation of the base 40 around the axis of the connecting shaft 60 from affecting the contact between the charging contact 51 and the electric appliance 80 when the wire of the second end 12 is changed during charging.

[0049] Specifically, the charger further comprises a charging circuit board 52, which is arranged in the charging head 30 and is electrically connected with the first end portion 11 and the charging contact portion 51. The first end portion 11 is electrically connected with the charging contact portion 51 through the charging circuit board 52. The charging circuit board 52 can play the roles of voltage stabilization, voltage conversion, circuit protection and control, etc. By arranging 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 also do not need to rotate with the base 40, and further, the connection between the charging contact portion 51 and the charging circuit board 52 is more stable. The charging circuit board 52 can be a single-sided board, a double-sided board or a multi-layer board, and the type, model and size of the circuit board are not limited in the application.

[0050] As shown in Figures 2 to 4 some embodiments of the application, the first trace hole 411 has a first position on the rotatable track. The rotating assembly 20 further comprises a locking structure, which comprises a first locking member 71 and a second locking member 72. The first locking member 71 is connected with the charging head 30, and the second locking member 72 is connected with the base 40. When the first trace hole 411 is located at the first position, the second locking member 72 is locked with the first locking member 71 to realize the locking of the base 40 and the charging head 30. When the first trace hole 411 is located at the first position and the base 40 rotates relative to the charging head 30 under the action of an external force, the second locking member 72 drives the first locking member 71 to be unlocked to realize the unlocking of the base 40 and the charging head 30.

[0051] It can be understood that the specific position of the first position can be selected according to actual needs. The position and trace direction of the second end portion 12 are determined by the first trace hole 411. For example, as shown in the view angle, Figure 3 when the second end portion 12 extends along a straight line, the trace direction of the first trace hole 411 is usually parallel or approximately parallel to the orientation of the first trace hole 411. When the first trace hole 411 is located at the first position, the locking of the base 40 and the charging head 30 can be realized 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 further, the second end portion 12 can stably stay in the trace direction at this time, preventing the base 40 from driving the second end portion 12 to rotate due to factors such as vibration or accidental touch, and playing the role of rotation to position. When it is necessary to adjust the trace direction of the second end portion 12, the user can rotate the base 40 so that the base 40 rotates relative to the charging head 30 under the action of an external force, and drives the second locking member 72 to be unlocked with the first locking member 71.

[0052] Further, the first wire hole 411 has a second position on the rotatable track, the orientation of the first wire hole 411 at the first position is different from the orientation of the first wire hole 411 at the second position, when the first wire hole 411 is at the second position, the second locking part 72 is locked with the first locking part 71 to realize the locking of the base 40 and the charging head 30; when the first wire hole 411 is at the second position and the base 40 rotates relative to the charging head 30 under the action of an external force, the second locking part 72 is unlocked with the first locking part 71. It should be noted that the first wire hole 411 is at the first position, Figure 1 the first wire hole 411 is at the second position, Figure 5 For example, the first wire hole 411 is at the first position, the wire direction of the second end 12 at the first position is different from the wire direction of the second end 12 at the second position, the first wire hole 411 at the first position and the second position can be fixed by the locking of the first locking part 71 and the second locking part 72, so that the second end 12 can be stably stayed in multiple wire directions, preventing the base 40 from rotating the second end 12 due to factors such as vibration or accidental touch.

[0053] Further, the first wire hole 411 is rotated 90 degrees from the first position to the second position along the first rotation direction R1, so that when the first wire hole 411 is rotated from the first position to the second position, the wire direction of the second end 12 has a large change (the change angle is 90 degrees or close to 90 degrees), which can adapt to more scene requirements; wherein the first rotation direction R1 can be clockwise or counterclockwise.

[0054] It should be noted that the first wire hole 411 can also be locked at more positions by the first locking part 71 and the second locking part 72, 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 the orientation of the first wire hole 411 at the second position and the first position, when the first wire hole 411 is at the third position, the second locking part 72 is locked with the first locking part 71 to realize the locking of the base 40 and the charging head 30; when the first wire hole 411 is at the third position and the base 40 rotates relative to the charging head 30 under the action of an external force, the second locking part 72 is unlocked with the first locking part 71. Wherein, the first position can be the orientation of the first wire hole 411 at 12 o'clock, the second position can be the orientation of the first wire hole 411 at 3 o'clock, and the third position can be the orientation of the first wire hole 411 at 9 o'clock.

[0055] In some embodiments, the first locking member 71 and the second locking member 72 are both arranged in the base 40, the first locking member 71 is sleeved on the connecting shaft 60 and fixedly connected with the charging head 30 through the connecting shaft 60, and the second locking member 72 is sleeved on the connecting shaft 60 and rotatably connected with the connecting shaft 60. It can be understood that the connecting shaft 60 is fixed with the charging head 30 and inserted into the base 40, the connecting shaft 60 can be integrally formed with the charging head 30, or separately formed with the charging head 30 and spliced through bonding, clamping, threaded connection or other ways, the first locking member 71 is fixed on the connecting shaft 60, thereby realizing the fixed connection with the charging head 30, the base 40 is rotatably connected with the connecting shaft 60, when the base 40 rotates relative to the charging head 30 and the connecting shaft 60 around 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, and the locking and unlocking of the second locking member 72 and the first locking member 71 is more convenient.

[0056] Continuing to refer to Figures 2 to 4 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 clamping block 73 and the clamping groove 74 is arranged on the side of the first locking member 71 facing the second locking member 72, and the other of the clamping block 73 and the clamping groove 74 is arranged on the side of the second locking member 72 facing the first locking member 71.

[0057] In some embodiments, when the first wiring hole 411 is located at the first position, the clamping block 73 and the clamping groove 74 are clamped to realize the locking of the base 40 and the charging head 30, when the first wiring hole 411 is located at the first position and the base 40 rotates relative to the charging head 30 under the action of an external force, the clamping block 73 and the clamping groove 74 are separated to realize the unlocking of the base 40 and the charging head 30, so as to realize the locking and unlocking of the first locking member 71 and the second locking member 72 through the cooperation of the clamping block 73 and the clamping groove 74, which can play a role of rotating to the right position for the user, and has the characteristics of interestingness, playing, stress relieving, etc., and can provide a better experience for the user.

[0058] Further, the locking block 73 extends circumferentially along the connecting shaft 60. The outer surface of the locking 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 locking 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 located at opposite ends of the top side surface 731. The first end surface 732 extends obliquely from the top side surface 731 in a direction away from the top side surface 731, and the second end surface 733 extends obliquely from the top side surface 731 in a direction away from the top side surface 731. The slot 74 extends circumferentially along the connecting shaft 60. The slot wall of the slot 74 includes a first slot wall surface 741 and a second slot wall surface 742. When the first wiring 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, with Figure 3 Taking the shown perspective as an example, the first end face 732 and the second end face 733 extend at an angle, which can play a guiding role. When the first wiring hole 411 is in the first position and the base 40 is rotated clockwise, the second locking member 72 is rotated clockwise, and the first groove wall 741 slides along the first end face 732, making the separation of the locking block 73 and the locking groove 74 smoother. When the base 40 is rotated counterclockwise, the second locking member 72 is rotated clockwise, and the second groove wall 742 slides along the second end face 733, making the separation of the locking block 73 and the locking groove 74 smoother. Thus, the locking block 73 and the locking groove 74 can be smoothly engaged and disengaged when the base 40 is rotated clockwise and counterclockwise, preventing jamming.

[0059] In some embodiments, multiple slots 74 and multiple blocks 73 are provided. The multiple slots 74 are arranged at intervals around the connecting shaft 60 in the circumferential direction, and the multiple blocks 73 are arranged at intervals around the connecting shaft 60 in the circumferential direction, so that the base 40 can be locked and fixed with the charging head 30 in multiple positions (such as when the first wiring hole 411 is in the first position, the second position, and the third position). The number of slots 74 and blocks 73 can be two, three, or more.

[0060] In some embodiments, the rotating assembly 20 further comprises a reset member 75 sleeved on the connecting shaft 60, the reset member 75 is connected with the base 40 and the charging head 30, and the reset member 75 is configured to provide the second locking member 72 with an elastic force to rotate towards the first locking member 71 to be locked 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 is in the unlocked state with the first locking member 71, the reset member 75 is in a compressed or stretched state, and the reset member 75 provides the second locking member 72 with the elastic force 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 to the second locking member 72 can make the rotation of the base 40 more smooth and light, and the user experience can be improved.

[0061] As shown in Figure 6 some embodiments of the present application, the rotating assembly 20 further comprises a limiting structure, the limiting structure comprises a first limiting member 76 and a second limiting member 77. The first limiting member 76 is connected with the charging head 30, and the second limiting member 77 is connected with the base 40. The second limiting member 77 is arranged along the circumference of the connecting shaft 60 with the first limiting member 76. When the base 40 is rotated relative to the charging head 30 along a first rotation direction R1 to abut the second limiting member 77 with 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 is rotated relative to the charging head 30 along a second rotation direction R2 to abut the second limiting member 77 with the first limiting member 76, the first limiting member 76 prevents the base 40 from rotating along the second rotation direction R2, and the second rotation direction R2 is opposite to the first rotation direction R1.

[0062] 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 to a certain angle, the second limiting member 77 will abut 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 to a certain angle, the second limiting member 77 will also abut 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. Thus, the continuous rotation of the base 40 along one direction for multiple turns can be prevented, and the part of the charging cord 10 located in the base 40 and the charging head 30 can be prevented from being wound.

[0063] The second limiting member 77 can be rotated 180 degrees to abut against the other end of the first limiting member 76, for example, the second limiting member 77 is rotated to abut against one end of the first limiting member 76 along the first rotation direction R1, and when the second limiting member 77 is rotated 180 degrees along the second rotation direction R2, the second limiting member 77 abuts against the other end of the first limiting member 76.

[0064] In some embodiments, the base 40 is provided with a through hole 42 through which the connecting shaft 60 passes 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 with the charging head 30 through the connecting shaft 60, and the second limiting member 77 is arranged on the inner side wall of the through hole 42. The through hole 42 can provide accommodation space for the first limiting member 76 and the second limiting member 77, and the overall volume of the charger can be reduced, so that the charger is more convenient to carry.

[0065] Referring to Figure 5 In some embodiments, the charging head 30 includes a first housing 31 and a second housing 32 that are detachably connected, and the base 40 includes a third housing 43 and a fourth housing 44 that are detachably connected, and the first housing 31, the second housing 32, the third housing 43, and the fourth housing 44 are sequentially stacked in the direction of the charging contact portion 51 toward the electrical appliance 80, so that the base 40 and the charging head 30 can be disassembled, and the components in the base 40 and the charging head 30 can be easily repaired and maintained.

[0066] In some embodiments, the charging contact 51 comprises a charging sheet set 511 and a data conductive set 512; the charging sheet set 511 comprises a first charging sheet 511a and a second charging sheet 511b arranged along a first direction XX, the first direction XX being perpendicular to the axial direction of the connecting shaft 60, the first charging sheet 511a and the second charging sheet 511b can be positive and negative charging sheets respectively, and are used to be in contact with the charging contacts on the electric appliance 80, thereby realizing the electrical connection between the power module of the electric appliance 80 and the charging cord 10; the data conductive set 512 is located between the first charging sheet 511a and the second charging sheet 511b, and comprises a plurality of conductive pins 512a arranged along a second direction YY, the second direction YY being perpendicular to the first direction XX and the axial direction of the connecting shaft 60, and the plurality of conductive pins 512a can comprise positive and negative conductive pins 512a, and are used to be in contact with the conductive contacts on the electric appliance 80, thereby realizing the data transmission between the power module and the charging cord 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 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, and the volume of the charging head 30 can be further reduced, thereby reducing the volume of the charger and making the charger more miniaturized.

[0067] Specifically, the charging cord 10 can comprise a positive electrical connection line, a negative electrical connection line, a positive signal transmission line and a negative signal transmission line, which are all welded with the charging circuit board 52 to be electrically connected with the positive and negative charging sheets and the positive and negative conductive pins 512a respectively.

[0068] In some embodiments, the charging cord 10 comprises a magnet for magnetic attraction with the electric appliance 80, and the magnet is used to be magnetically attracted with the electric appliance 80 to fix the charger on the electric appliance 80, and the magnet is arranged on the charging cord 10, which can prevent the magnet from interfering with the electronic elements in the first and second housings 31 and 32.
