[0002] Charging devices can charge electronic devices such as TWS (True Wireless Stereo) headphones, smartphones, smartwatches, etc. Setting the charging structure of the charging device to a retractable structure can make the charging device compact and easy to store. However, to meet the sliding and retracting requirements, the retractable charging structure generally reserves an assembly gap, which can easily cause the charging element to move unsteadily during the retraction process. Utility Model Content

[0006] The charging assembly includes a moving member and a first charging element, wherein the moving member includes a moving body and a mating portion provided on the moving body, and the moving member is movably provided in the accommodating cavity so that the moving body can be extended or retracted relative to the accommodating cavity along its length. The first charging element is mounted on the moving body and has a first charging plane parallel to the length of the moving body.

[0007] In which, the limiting portion has a limiting surface, the matching portion is arranged in the accommodating cavity and has a matching surface, the matching surface forms an angle with the first charging plane, and the movable body has a first position extending relative to the accommodating cavity. In the first position, the matching surface is in contact with the limiting surface to limit the movement of the movable part in a direction perpendicular to the length direction of the movable body.

[0008] Based on the charging device of the embodiment of the present application, by setting the limiting surface of the limiting part and the matching surface of the matching part to be an inclined surface, in the first position of the moving part, the matching surface and the limiting surface are in contact, and the matching surface and the limiting surface interact with each other in the length direction of the moving body to prevent the moving part from separating from the shell assembly.

[0027] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0028] The inventors have discovered that configuring a retractable charging structure for a charging device can make the overall structure of the charging device compact and easy to store. However, to meet assembly requirements, retractable charging structures generally have a gap, which can easily cause the charging element to become unstable during extension and retraction. Based on this, the present invention provides a charging device.

[0029] like Figure 1Figure 1 is a schematic diagram of the three-dimensional structure of a charging device 10 according to an embodiment of the present application. The charging device 10 includes a housing assembly 100. The housing assembly 100 serves as the base carrier of the charging device 10 and supports and protects the other components of the charging device 10. The housing assembly 100 includes an accommodating cavity and an accommodating opening 1122 communicating with the accommodating cavity.

[0030] The charging assembly 200 includes a moving member 210 and a first charging element 300. The moving member 210 includes a moving body 211. The moving member 210 is movably disposed within the accommodating cavity along the length direction H of the moving body, such that the moving body 211 can extend or retract relative to the accommodating cavity at the accommodating opening 1122. The outer surface of the first charging element 300 includes a first charging plane 310. The first charging plane 310 is parallel to the length direction H of the moving body. The central axis of the first charging plane 310 is perpendicular to the plane of the accommodating opening 1122. The accommodating opening 1122 is provided on the outer peripheral wall 1121 of the housing assembly 100. Optionally, the outer contour of the first charging plane 310 is circular, rectangular, or a regular polygon.

[0031] like Figure 1 As shown, when the mobile body 211 extends relative to the accommodating cavity 101, part of the mobile body 211 extends outside the housing assembly 100, and the first charging plane 310 extends outside the housing assembly 100, so that the electronic device can be supported on the first charging plane 310, and the first charging element 300 charges the electronic device supported on the first charging plane 310. Figure 2 As shown, when the moving member 210 is retracted relative to the accommodating cavity 101, the moving body 211 is accommodated in the accommodating cavity 101, and the first charging element 300 is accommodated in the accommodating cavity 101, so that the overall structure of the charging device 10 is compact, without protruding parts, and occupies a small space, making it easy to store and carry the charging device 10.

[0032] Combine Figure 3 and Figure 4 The housing assembly 100 includes a limiting portion 1011 provided in the accommodating cavity 101, the limiting portion 1011 has a limiting surface 1012, and the moving member 210 includes a mating portion 212 convexly provided on the outer surface of the moving body 211, combined with Figure 3 and Figure 5 The mating portion 212 has a mating surface 2120, which forms an angle with the first charging plane 310. The moving part 210 has a first position extending relative to the accommodating cavity 101. The first position is the maximum position of the moving part 210 extending from the accommodating cavity 101. The limiting surface 1012 abuts against the mating surface 2120 to prevent the moving part 210 from separating from the shell assembly 100 when the moving part 210 is in the first position, and to limit the moving body 211 from moving in a direction perpendicular to the length direction H of the moving body 211.

[0033] In order to facilitate the smooth movement of the moving member 210 within the accommodating chamber 101, an assembly gap is reserved between the moving member 210 and the wall surface of the housing assembly 100 that defines the accommodating chamber 101. When the extended portion of the moving member 210 is supported by an electronic device or subjected to external force, the existence of the assembly gap can easily cause the moving member 210 to wobble. In the embodiment of the present application, the first position of the moving member 210 is the optimal charging position, and the limiting surface 1012 of the limiting portion 1011 and the mating surface 2120 of the mating portion 212 are set as inclined surfaces to improve the stability of the moving member 210 when it is in the first position.

[0034] Specifically, the moving member 210 has a direction M of extending relative to the accommodating cavity 101 and a direction of retracting relative to the accommodating cavity 101, such as Figure 3 As shown, in the direction in which the moving body 211 extends relative to the accommodating cavity 101, the mating surface 2120 of the mating portion 212 is inclined toward the side close to the moving body 211. In the first position of the moving part 210, the mating surface 2120 is in contact with the limiting surface 1012. The mating surface 2120 and the limiting surface 1012 interact with each other in the length direction H of the moving body to prevent the moving part 210 from separating from the shell assembly 100. At the same time, the mating surface 2120 and the limiting surface 1012 interact with each other in the thickness direction A of the moving body 211 to prevent the moving part 210 from moving relative to the shell assembly 100 in the thickness direction A perpendicular to the moving body. The thickness direction A of the moving body is perpendicular to the first charging plane 310, so that the electronic device supported on the first charging plane 310 has good supporting stability. In this way, when designing the charging device 10, an assembly gap can be reserved for the movable member 210 to move smoothly relative to the housing assembly 100, and when the movable member 210 is extended to the charging position, the movable member 210 has good installation stability for the electronic device to support.

[0035] It is understandable that the electronic device is supported on the first charging plane 310, and it is particularly necessary to control the installation stability of the moving member 210 in the direction perpendicular to the first charging plane 310. In some embodiments, such as Figure 5 As shown, the mating portion 212 includes a first mating block 2121, and the mating surface 2120 of the first mating block 2121 forms an angle with a plane perpendicular to the thickness direction A of the movable body 211, so that when the mating surface 2120 is in contact with the limiting surface 1012, the mating surface 2120 and the limiting surface 1012 interact with each other in the thickness direction A of the movable body 211, thereby limiting the position of the movable part 210 in the thickness direction A of the movable body 211, so that the electronic device has good bearing stability in the thickness direction A of the movable body 211 when it is supported on the first charging plane 310.

[0036] In some embodiments, the thickness direction A of the movable body corresponds to the direction of gravity. The outer surface of the movable body 211 includes an upper surface 2101 and a lower surface 2102, which are arranged opposite each other in the direction of gravity. The upper surface 2101 defines an opening for mounting the first charging element 300, and the first charging surface 310 of the first charging element 300 is located within the opening of the upper surface 2101. When the movable member 210 is extended, the gap between the movable member 210 and the housing assembly 100 in the direction of gravity easily causes the movable member 210 to move in the direction of gravity. Therefore, a first mating block 2121 is provided, and the housing assembly 100 is provided with a limiting portion 1011, which is arranged opposite the first mating block 2121 in the direction of gravity. The limiting surface of the limiting portion 1011 mates with the mating surface 2120 of the first mating block 2121 to limit the position of the movable member 210 in the direction of gravity.

[0037] There are one or more first matching blocks 2121 disposed on the upper surface 2101 of the moving body 211 .

[0038] In the direction of gravity, when there is only one first mating block 2121 protruding from the upper surface 2101 of the mobile body 211, in the direction M in which the mobile body 211 extends relative to the accommodating cavity 101, the first mating block 2121 is located behind the first charging plane 310. Furthermore, the first mating block 2121 extends along the width direction B of the mobile body and is in an elongated strip shape. The width direction B of the mobile body is parallel to the first charging plane 310 and perpendicular to the thickness direction A of the mobile body. The size of the mating surface 2120 of the first mating block 2121 is increased. In this case, one or more limiting portions 1011 may be provided corresponding to the mating surface 2120 of the first mating block 2121. When there is only one limiting portion 1011, the size of the limiting surface 1012 of the limiting portion 1011 in the width direction B of the mobile body is the same as the size of the mating surface 2120 of the first mating block 2121, and the ends are aligned. When there are multiple limiting portions 1011, the multiple limiting portions 1011 are spaced apart and evenly distributed along the width direction B of the mobile body.

[0039] In the direction of gravity, when there are multiple first mating blocks 2121 disposed on the upper surface 2101 of the mobile body 211, in the direction M in which the mobile body 211 extends relative to the accommodating cavity 101, the multiple first mating blocks 2121 are located behind the first charging plane 310, and the multiple first mating blocks 2121 are arranged at intervals in the width direction B of the mobile body. In this case, the number of limiting portions 1011 corresponding to the multiple first mating blocks 2121 can be one or more. When there is one limiting portion 1011, the limiting surface 1012 of the limiting portion 1011 is aligned with the mating surfaces 2120 of the multiple first mating blocks 2121. When there are multiple limiting portions 1011, the limiting surfaces 1012 of the multiple limiting portions 1011 are aligned with the mating surfaces 2120 of the multiple first mating blocks 2121 in a one-to-one correspondence.

[0040] In some embodiments, all first mating blocks 2121 are arranged on the upper surface 2101 of the movable body 211, the shell assembly 100 has a front opening 1101 connected to the accommodating cavity 101, the movable body 211 is sequentially penetrated by the front opening 1101 and the accommodating opening 1122, and the lower surface 2102 of the movable body 211 is supported on the wall surface of the shell assembly 100 that limits the front opening 1101. When the movable part 210 is in the extended first position, the mating surface 2120 of the first mating block 2121 is in contact with the limiting surface 1012 of the limiting portion 1011, thereby limiting the position of the movable part 210 in the direction of gravity.

[0041] In some other embodiments, a portion of the first mating blocks 2121 may be protruded from the upper surface 2101 of the movable body 211, and another portion of the first mating blocks 2121 may be protruded from the lower surface 2102 of the movable body 211, and the shell assembly 100 may be provided with a limiting portion 1011 corresponding to these first mating blocks 2121, so as to further limit the stability of the movable member 210 in the direction of gravity when the movable member 210 is in the extended first position.

[0042] In some embodiments, the housing assembly 100 includes an intermediate housing 111, which has a receiving cavity 101 and a front opening 1101 communicating with the receiving cavity 101. The front opening 1101 corresponds to the receiving opening 1122. The moving member 210 extends out of the housing assembly 100 from the receiving cavity 101 through the front opening 1101 and the receiving opening 1122 in sequence. The wall surface of the intermediate housing 111 defining the receiving cavity 101 includes a top wall surface 1105 and a bottom wall surface 1104. The top wall surface 1105 and the bottom wall surface 1104 are arranged relative to each other in the thickness direction A of the moving body. The upper surface 2101 of the moving body 211 and the lower surface 2102 of the moving body 211 are respectively slidably fitted with the wall surface of the intermediate housing 111 defining the front opening 1101. The first mating block 2121 protruding from the upper surface 2101 of the moving body 211 is mated with the intermediate housing 111. The sliding fit of the top wall 1105 of the movable body 211, when the lower surface 2102 of the movable body 211 is also provided with a first matching block 2121, the first matching block 2121 of this part slides and fits with the wall surface of the bottom wall 1104 of the intermediate housing 111. In this way, during the movement of the movable member 210 relative to the accommodating chamber 101, the interaction between the various wall surfaces enables the movable member 210 to move smoothly along the longitudinal direction H of the movable body, with a small contact area and low sliding resistance. In particular, due to assembly tolerances and sliding requirements, a certain gap inevitably exists at the sliding fit of the above-mentioned wall surfaces. When the movable member 210 is in the extended state, by setting the matching surface 2120 of the first matching block 2121 to fit with the limiting surface 1012 of the limiting portion 1011, it is no longer affected by the gap, and can directly ensure that the movable member 210 has good installation stability in the direction of gravity when extended.

[0043] Due to gravity, the moving member 210 needs to be supported by the bottom wall 1104 of the accommodating cavity 101. In some embodiments, such as Figure 6 As shown, the bottom wall 1104 is provided with a plurality of hollow grooves 11 to reduce the contact area between the moving body 211 and the bottom wall 1104, so as to facilitate the smooth movement of the moving member 210. In some other embodiments, when the lower surface 2102 of the moving body 211 is not provided with the first matching block 2121, one of the bottom wall 1104 and the lower surface 2102 of the moving body 211 is provided with a guide groove and the other is provided with a guide bar 1123. The guide groove extends along the length direction H of the moving body 211, and the guide bar 1123 is slidably provided in the guide groove to guide the moving member 210 to move along the length direction H of the moving body. Figure 6 As shown, a convex strip is formed between two adjacent hollow grooves 11a of the bottom wall surface 1104, wherein the two convex strips respectively form two guide strips 1123, and the lower surface 2102 of the movable body 211 is correspondingly provided with guide grooves corresponding to the two guide strips 1123.

[0044] In some embodiments, as Figure 7 As shown, there are multiple first mating blocks 2121, and the mating surfaces 2120 of the multiple first mating blocks 2121 are arranged axially symmetrically with respect to the first plane. The first plane passes through the central axis of the first charging plane 310 and is perpendicular to the first charging plane 310. When the mating surfaces 2120 of the multiple first mating blocks 2121 are aligned with the corresponding limiting surfaces 1012 of the limiting portions 1011, the force is evenly applied, thereby providing better limiting stability for the movable member 210. Similarly, when there is only one first mating block 2121, the mating surfaces 2120 of the first mating block 2121 are also arranged axially symmetrically with respect to the first plane.

[0045] In some embodiments, the mating portion 212 includes a second mating block 2122, and the mating surface 2120 of the second mating block 2122 forms an angle with a plane perpendicular to the width direction B of the moving body 211. The shell assembly 100 is provided with a limiting portion 1011 corresponding to the second mating block 2122. When the moving part 210 is extended to the first position, the mating surface 2120 of the second mating block 2122 is fitted with the limiting surface 1012 of the corresponding limiting portion 1011 to limit the position of the moving part 210 in the width direction B of the moving body.

[0046] In some embodiments, the outer contour of the cross section of the mobile body 211 in a direction perpendicular to the length direction H of the mobile body is rectangular. Specifically, the mobile body 211 includes two side surfaces 2103 arranged opposite to each other in the width direction B of the mobile body, and each side surface 2103 is connected between the upper surface 2101 and the lower surface 2102 of the mobile body 211. The number of the second matching blocks 2122 is multiple. In the width direction B of the mobile body, a part of the second matching blocks 2122 is protruded from one of the side surfaces 2103 of the mobile body 211, and another part of the second matching blocks 2122 is protruded from the other side surface 2103 of the mobile body 211. In the direction in which the body 211 extends relative to the accommodating cavity 101, the mating surfaces 2120 of the second mating blocks 2122 arranged on the opposite sides of the moving body 211 are close to each other, and the second mating block 2122 and the first mating block 2121 cooperate with each other to limit the position of the moving part 210 in the first position from multiple directions, further improving the installation stability of the moving part 210 in the first position. At the same time, adding the second mating block 2122 can increase the action area of the moving part 210 and the shell assembly 100, improve the structural strength, and prevent the area from being small when the first mating block 2121 is used alone to act on the shell assembly 100, thereby preventing the moving part 210 from separating from the shell assembly 100.

[0047] In some embodiments, in the width direction B of the moving body, the mating surface 2120 of the second mating block 2122 provided on one side of the moving body 211 and the mating surface 2120 of the second mating block 2122 provided on the other side of the moving body 211 are axially symmetrically arranged about the first plane, so as to further improve the limiting stability of the second mating block 2122 on the moving part 210 in the width direction B of the moving body. The wall surface of the accommodating cavity 101 defined by the intermediate shell 111 also includes a left wall surface 1105 and a right wall surface 1104. In the process of the moving part 210 moving along the length direction H of the moving body, the second matching block 2122 provided on one side of the moving body 211 slides and fits with the left wall surface 1105, and the second matching block 2122 provided on the other side of the moving body 211 slides and fits with the right wall surface 1104. The two side surfaces 2103 of the moving body 211 slide and fit with the wall surface of the front opening 1101 defined by the intermediate shell 111 respectively, reducing the contact area so that the moving part 210 can slide smoothly and guide the moving part 210 to move in the length direction H of the moving body. Similarly, due to the sliding requirements and assembly clearance, there is also a certain gap between the wall surfaces of the above-mentioned sliding fitting. When the moving part 210 is in the first position, the mating surface 2120 of the second mating block 2122 fits with the limiting surface 1012 of the corresponding limiting part 1011, which is not affected by the gap and limits the position of the moving part 210 in the width direction B of the moving body.

[0048] In some embodiments, the charging device 10 further includes a push-type locking assembly and an ejection assembly 800. The push-type locking assembly is used to lock the position of the moving member 210 relative to the accommodating chamber 101 when the moving member 210 is retracted into the accommodating chamber 101. After the push-type locking assembly releases the lock on the moving member 210, the ejection assembly 800 pushes the moving member 210 along the length direction H of the moving body and extends out of the housing assembly 100. The number of ejection assemblies 800 is multiple, and the multiple sets of ejection assemblies 800 are arranged axially symmetrically about the first plane. The mating surfaces 2120 of the second mating blocks 2122 disposed on opposite sides of the moving body 211 are also arranged axially symmetrically about the first plane. In this way, when the multiple sets of ejection assemblies 800 push the moving member 210 out, the second mating blocks 2122 disposed on opposite sides of the moving body 211 exert a more uniform force on the housing assembly 100, preventing the uneven force exerted by the moving member 210 on the housing assembly 100, which may cause the moving member 210 to deflect within the plane where the first charging plane 310 is located.

[0049] In some embodiments, the pop-up assembly 800 includes an elastic member 810, and the elastic member 810 pushes the mobile body 211 to extend relative to the accommodating cavity 101 through the force of restoring its elastic deformation. The wall surface of the housing assembly 100 that defines the accommodating cavity 101 includes a front wall surface 1102 and a rear wall surface 1102. The front wall surface 1102 and the rear wall surface 1102 are arranged relative to each other along the longitudinal direction H of the mobile body. The front wall surface 1102 is provided with a front opening 1101. One end of the elastic member 810 can be installed on the rear wall surface 1102 and the other end can be installed on the rear wall surface 1102. Towards the front wall 1102, when the push-type locking assembly releases the lock on the moving part 210, the elastic part 810 stretches to restore its elastic deformation, pushing the moving part 210 out, so that the moving part 210 extends out of the shell assembly 100, or, one end of the elastic part 810 is installed on the front wall 1102 and the other end faces the rear wall 1102. When the push-type locking assembly releases the lock on the moving part 210, the elastic part 810 contracts to restore its elastic deformation, pulling the moving part 210 back, so that the moving part 210 extends out of the shell assembly 100.

[0050] In some embodiments, the pop-up assembly 800 further includes a limiting rod 820. The mobile body 211 has a plurality of limiting holes facing the rear wall surface 1102. The plurality of limiting holes are arranged in a one-to-one correspondence with the limiting rods 820 of the plurality of elastic assemblies. The axial direction of the limiting rod 820 is parallel to the longitudinal direction H of the mobile body. One end of the limiting rod 820 is mounted on the rear wall surface 1102, and the other end extends into the limiting hole of the mobile body 211. The outer surface of the limiting rod 820 is slidably fitted with the wall surface of the mobile body 211 defining the limiting hole, so as to guide the mobile member 210 to move along the longitudinal direction H of the mobile body. The elastic member 810 can be a telescopic spring, which is sleeved around the outer circumference of the limiting rod 820 and guided by the limiting rod 820 to extend and retract along the longitudinal direction H of the mobile body.

[0051] like Figure 6 As shown, the charging device 10 also includes a pre-tightening assembly, which includes a first pre-tightening portion 910 and a second pre-tightening portion 920. The first pre-tightening portion 910 is installed on the shell assembly 100, and the second pre-tightening portion 920 is installed on the movable body 211. The first pre-tightening portion 910 cooperates with the second pre-tightening portion 920 to make the mating surface 2120 of the mating portion 212 abut against the limiting surface 1012 of the limiting portion 1011, thereby limiting the position of the movable part 210 in the longitudinal direction H of the movable body and preventing the movable part from being retracted under a slight external force. At the same time, the tightness of the fitting between the mating surface 2120 and the limiting surface 1012 is improved to further improve the position of the movable part 210 perpendicular to the preset central axis direction, thereby improving the installation stability of the movable part 210 in the first position.

[0052] In some embodiments, one of the first pre-tightening portion 910 and the second pre-tightening portion 920 is magnetic, and the other is magnetic or contains iron material. The first pre-tightening portion 910 and the second pre-tightening portion 920 use magnetic action to make the limiting surface 1012 of the limiting portion 1011 abut against the mating surface 2120 of the mating portion 212, while at the same time facilitating the application of a certain force to retract the moving part 210 into the accommodating cavity 101.

[0053] The first pre-tightening portion 910 has a first top end 911 and a second top end 912 oppositely disposed along the length direction H of the moving body. In the direction M in which the moving member 210 extends relative to the accommodating cavity 10 a , the first top end 911 is located in front of the second top end 912 .

[0054] In some embodiments, when the first pre-tightening portion 910 and the second pre-tightening portion 920 cause the limiting surface 1012 to abut against the mating surface 2120 through magnetic attraction, the first pre-tightening portion 910 is magnetic, and the magnetic center of the first pre-tightening portion 910 is located at the first top end 911. In the direction M in which the movable body 211 extends relative to the accommodating cavity 101, the first top end 911 is located in front of the second pre-tightening portion 920. The magnetic attraction between the first pre-tightening portion 910 and the second pre-tightening portion 920 can pull the second pre-tightening portion 920 toward the first pre-tightening portion 910, so that the limiting surface 1012 can abut against the mating surface 2120. At this time, the second pre-tightening portion 920 may or may not be magnetic.

[0055] In some embodiments, as Figure 8As shown, in the direction in which the moving body 211 extends relative to the accommodating cavity 101, the distance from the second top end 912 to the front opening 1101 can be set to be smaller than the distance from the second top end 912 to the rear wall surface 1102. The area covered by the first pre-tightening portion 910 in the moving direction of the moving member 210 is smaller. At this time, after the second pre-tightening portion 920 moves to the area near the first pre-tightening portion 910, the limiting surface 1012 is abutted against the mating surface 2120 by magnetic attraction. Optionally, when the elastic component includes an elastic member 810, the elastic member 810 can push the moving member 210 to move the second pre-tightening portion 920 to the area near the first pre-tightening portion 910. During the entire movement process of the moving member 210, the elastic member 810 is connected to the moving body 211.

[0056] In some embodiments, as Figure 9 As shown, in the direction M in which the moving body 211 extends relative to the accommodating chamber 101, the distance from the second top 912 to the front opening 1101 is greater than or equal to the distance from the second top 912 to the rear wall 1102, the first pre-tightening portion 910 is magnetic, and the magnetic center of the first pre-tightening portion 910 is located at the first top 911, so that the area covered by the first pre-tightening portion 910 in the moving direction of the moving part 210 is larger, so that the second pre-tightening part can be attracted by the first pre-tightening portion 910 when it is far away from the front opening 1101, and then under the action of the magnetic attraction between the first pre-tightening part and the second pre-tightening part, the moving part 210 is driven to extend out of the accommodating chamber 101. Optionally, when the elastic component includes an elastic part 810, the elastic part 810 can provide a boosting force so that after the moving part 210 is started, the magnetic attraction between the first pre-tightening part 910 and the second pre-tightening part 920 drives the second pre-tightening part 920 to move toward the magnetic center of the first pre-tightening part 910, thereby driving the moving part 210 to extend out of the accommodating cavity 101. During the movement of the moving part 210, the elastic part 810 can be separated from the moving part 210, and the second pre-tightening part 920 moves toward the end close to the magnetic center of the first pre-tightening part 910, thereby making the limiting surface 1012 abut against the mating surface 2120.

[0057] In some other embodiments, in the direction in which the moving body 211 extends relative to the accommodating chamber 101, when the distance from the second top 912 to the front opening 1101 is less than the distance from the second top 912 to the rear wall 1102, the length of the elastic member 810 may be set to be shorter, and the elastic member 810 is separated from the moving member 210 during the process of the moving member 210 extending out of the accommodating chamber 101; or, in the direction in which the moving body 211 extends relative to the accommodating chamber 101, when the distance from the second top 912 to the front opening 1101 is greater than or equal to the distance from the second top 912 to the rear wall 1102, the length of the elastic member 810 may be set to be longer, and the elastic member 810 is connected to the moving member 210 during the entire movement process of the moving member 210.

[0058] In some other embodiments, the first pre-tightening portion 910 may also be set to be non-magnetic, and in the direction M in which the movable body 211 extends relative to the accommodating cavity 101, the first top end 911 is located in front of the second pre-tightening portion 920. Similarly, the magnetic attraction between the first pre-tightening portion 910 and the second pre-tightening portion 920 can pull the second pre-tightening portion 920 closer to the first pre-tightening portion 910, so that the limiting surface 1012 can abut against the mating surface 2120.

[0059] In some embodiments, the first pre-tightening portion 910 and the second pre-tightening portion 920 are both magnetic, and the first pre-tightening portion 910 and the second pre-tightening portion 920 use magnetic mutual repulsion to push the limiting surface 1012 against the mating surface 2120. Optionally, the second pre-tightening portion 920 is arranged at a position adjacent to the rear wall of the housing assembly 100, so that the magnetic mutual repulsion between the first pre-tightening portion 910 and the second pre-tightening portion 920 pushes the moving member 210 out of the accommodating cavity 10a along the length direction of the moving body. The embodiment of the present application does not limit the position where the first pre-tightening portion 910 is installed in the housing assembly 100. The installation position of the first pre-tightening portion 910 can meet the subsequent conditions, that is, the condition is: the magnetic mutual repulsion between the first pre-tightening portion 910 and the second pre-tightening portion 920 pushes the moving member 210 in the same direction as the elastic component pushes the moving member 210 to move, so that when the moving body 211 is in the first position, the limiting surface 1012 can abut against the mating surface 2120.

[0060] In some embodiments, the push-type locking assembly includes a push-type lock buckle 610 and a buckle. The push-type lock buckle 610 is located at the movable member 210, and the buckle is located in the accommodating chamber 101. The push-type lock buckle 610 adopts a self-locking design. When the push-type lock buckle 610 is pressed against the buckle, the push-type lock buckle 610 can be locked with the buckle, and when the push-type lock buckle 610 is pressed against the buckle again, the push-type lock buckle 610 can release the buckle, thereby releasing the lock. For example, when the movable member 210 is retracted into the accommodating chamber 101, the push-type lock buckle 610 is locked with the buckle in cooperation with the buckle. By pressing the movable member 210, the push-type lock buckle 610 is pressed against the buckle. At this time, the push-type lock buckle 610 and the buckle are released from the accommodating chamber 101, and the movable member 210 extends from the accommodating chamber 101 under the drive of the elastic member 810. When the movable member 210 needs to be stored, the movable member 210 is pressed back into the accommodating cavity 101. At this time, the push-type lock buckle 610 is pressed against the buckle again, and the push-type lock buckle 610 and the buckle are again engaged to lock the movable member 210. It should be noted that the self-locking design of the push-type lock buckle 610 is within the scope of understanding of those skilled in the art and will not be described in detail here.

[0061] In some embodiments, the intermediate housing 111 having the accommodating cavity 101 includes a first housing 1111 and a second housing 1112. The first housing 1111 and the second housing 1112 are arranged relative to each other along the thickness direction A of the movable body and are spliced to define the accommodating cavity 101 and a front opening 1101 communicating with the accommodating cavity 101. At least one of the first housing 1111 and the second housing 1112 has a limiting portion 1011. The split design of the intermediate housing 111 also facilitates the processing of the intermediate housing 111 and facilitates the installation of structural components such as the moving part 210 and the elastic component within the accommodating cavity 101.

[0062] The housing assembly 100 includes a housing body 110, and the charging assembly 200 is disposed within the housing body 110. The housing body 110 includes a peripheral side wall 1121, which is provided with an accommodating opening 1122. The accommodating opening 1122 is provided corresponding to the front opening 1101 so that the accommodating opening 1122 communicates with the accommodating chamber 101. The movable body 211 passes through the accommodating opening 1122 to extend or retract relative to the accommodating chamber 101, so that the portion of the movable member 210 extending from the housing assembly 100 is located on the side of the housing assembly 100. Specifically, the housing body 110 includes an outer shell 112 and an intermediate shell 111. The intermediate shell 111 is disposed within the interior space of the outer shell 112, and the outer peripheral wall of the outer shell 112 serves as the peripheral side wall 1121 of the housing body 110.

[0063] The first charging element 300 of the charging assembly 200 is located within the mobile body 211 to charge electronic devices carried on the first charging surface 310. When configuring the charging assembly 200, the positions of the moving member 210, the first charging element 300, and other structural components of the charging assembly 200 can be arranged based on the weight distribution, so that the overall weight distribution of the charging assembly 200 is symmetrical about the predetermined central axis.

[0064] The charging device 10 further includes a second charging element 400 having a second charging plane 410 for charging electronic devices carried on the second charging plane 410. In the thickness direction A of the mobile body 211, a portion of the second charging element 400 is installed inside the housing body 211 and is located on one side of the first charging element 300. The second charging element 400 has a second charging plane 410 exposed to the outer surface of the housing body and is used to charge electronic devices carried on the second charging plane 410. Alternatively, please refer to Figure 3 In the direction of gravity, the second charging component 400 is located above the first charging component 300, and the shell body 110 also includes an intermediate wall, the outer surface of which is provided with an opening for installing the second charging component 400, so that the second charging plane 410 is exposed to the outer surface of the shell body 110.

[0065] The charging device 10 also includes a third charging element 500 having a third charging surface 510 for charging electronic devices placed on the third charging surface 510. The housing assembly 100 also includes a flip cover 130, which is rotatably mounted on the housing body 110 relative to the middle wall. The flip cover 130 has a top wall facing away from the middle wall and defines an opening for accommodating the third charging element 500, exposing the third charging surface 510 to the outer surface of the flip cover 130. The flip cover 130 has an open state and a closed state. In the closed state, the flip cover 130 is positioned above the housing body 110. In the open state, the flip cover 130 is positioned at an angle relative to the second charging surface 410, exposing the second charging surface 410 and allowing electronic devices to be placed on the second charging surface 410 for charging.

[0066] The first charging element 300, the second charging element 400, and the third charging element 500 of the embodiment of the present application can be wireless charging elements, and can charge electronic devices such as smart watches through wireless charging. The first charging element 300, the second charging element 400, and the third charging element 500 can support MagSafe charging connection technology, etc., which allows electronic devices with magnetic attraction to automatically attach to the corresponding charging element and establish an electrical connection by approaching the first charging element 300, the second charging element 400, and the third charging element 500 for charging.

[0067] The first charging element 300, the second charging element 400, and the third charging element 500 are respectively used to charge different electronic devices. In other words, in this embodiment, the first charging element 300, the second charging element 400, and the third charging element 500 can charge three electronic devices at the same time. For example, by operating the movable part 210 of the charging assembly 200 to pop out from the housing assembly 100, a smart watch can be placed on the first charging plane 310 and charged by the first charging element 300; by closing the flip cover 130, a smartphone can be placed on the third charging plane 510 of the flip cover 130 and charged by the third charging element 500; by flipping up the flip cover 130, the second charging plane 410 of the housing body 110 can be vacated, and headphones (such as TWS headphones, etc.) can be placed on the second charging plane 410 and charged by the second charging element 400. The first charging element 300 , the second charging element 400 , and the third charging element 500 are compact in structure, making the overall size of the charging device 10 smaller and the space occupied by the charging device 10 smaller. In other words, the charging device 10 of this embodiment can achieve a three-in-one charging module design for a smartwatch, a smartphone, and headphones with a relatively small size.

[0068] In one embodiment, the charging device 10 further includes a circuit board 600 and a power interface 700. The circuit board 600 is disposed within the interior space of the housing assembly 100 and is electrically connected to the power interface 700. Furthermore, the first charging element 300, the second charging element 400, and the third charging element 500 are all electrically connected to the circuit board 600. The power interface 700 is also used to electrically connect to an external power source, thereby transmitting electrical energy provided by the external power source through the circuit board 600 to the first charging element 300, the second charging element 400, and the third charging element 500, respectively.

[0069] In one embodiment, the charging device 10 does not include a power supply. The first, second, and third charging components 300, 400, and 500 are all electrically connected to an external power supply via the circuit board 600 and the power interface 700, so that the external power supply provides electrical energy to charge the electronic device. Of course, in other embodiments, the housing assembly 100 of the charging device 10 may include a power supply to supply power to the first, second, 400, and third charging components 500, thereby charging the electronic device. This is not a limitation herein.
