Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of circuit device for power distribution, in particular to an electronic device accessory. BACKGROUND

[0002] In order to improve the convenience of people's daily life, various electronic devices have been produced. As one of the important accessories of electronic devices, the charger can charge the electronic products to maintain the endurance of the electronic products.

[0003] The charger generally includes a charging assembly and a wire material which are electrically connected to each other. The charging assembly can be electrically connected to an external power supply and convert the current. The wire material provides the required current to the electronic device to realize charging. However, the wire material is generally long and flexible, and is prone to knotting and entanglement. CONTENT OF THE UTILITY MODEL

[0004] To solve the above technical problems, the present application provides an electronic device accessory. The first fixing mechanism on the shell and the second fixing mechanism on the wire material cooperate to fix the wire material relative to the shell after being wound on the shell, thereby reducing the probability of problems such as knotting and entanglement of the wire material.

[0005] The present application provides an electronic device accessory, which comprises: a shell having an accommodation space, the shell comprising a circumferential side wall, the circumferential side wall being provided with a first fixing mechanism; a charging assembly, part of which is accommodated in the accommodation space, for electrically connecting to an external power supply or an electronic device; and a wire material, at least part of which is accommodated in the accommodation space and electrically connected to the charging assembly, the wire material being provided, at least in part, with a second fixing mechanism corresponding to the first fixing mechanism, the wire material being wound on the shell, and the wire material being fixed on the circumferential side wall of the shell by the first fixing mechanism and the second fixing mechanism when and / or after being wound.

[0006] In the technical scheme of the present application, the circumferential side wall of the shell is provided with the first fixing mechanism, and the wire material is provided with the second fixing mechanism which can cooperate with the first fixing mechanism. Therefore, the wire material can be wound on the circumferential side wall, and the position of the wire material relative to the circumferential side wall is fixed by the first fixing mechanism and the second fixing mechanism, so as to realize the winding arrangement of the wire material, which is simple in structure and convenient to use. Since the charging assembly is partially accommodated in the accommodation space, the shell can protect the part of the charging assembly located in the accommodation space.

[0007] In some embodiments, the wire material comprises: a connector provided with the second fixing mechanism, the wire material being fixed on the shell by the second fixing mechanism on the connector and the first fixing mechanism on the shell after being wound.

[0008] The wire can be electrically connected to the electronic device through the joint to realize the transmission of current from the charging assembly to the electronic device. The wire can also be electrically connected to an external power source through the joint to perform conversion or storage of the current. The second fixing mechanism provided on the joint can fix one end of the wire after winding, so that the whole formed after winding of the wire is fixed. The second fixing mechanism provided on the joint can fix the joint, so as to reduce the shaking of the joint and reduce the wear degree of the joint.

[0009] In some embodiments, the first fixing mechanism is provided on the peripheral side wall; the wire comprises a wire body, at least part of the wire body is provided with the second fixing mechanism, and the wire is fixed on the peripheral side wall of the shell through the cooperation between the second fixing mechanism on the wire body and the first fixing mechanism on the peripheral side wall during winding.

[0010] Thus, the wire body is fixed on the peripheral side wall through the cooperation of the first fixing mechanism and the second fixing mechanism, which helps to neatly wind and store the wire body.

[0011] In some embodiments, the wire body comprises at least one wire segment, the length of the wire segment is equal to the circumference of the peripheral side wall, at least one second fixing mechanism is provided on each wire segment, and the wire is fixed on the peripheral side wall of the shell through the cooperation between the second fixing mechanism on the wire segment and the first fixing mechanism on the peripheral side wall during winding.

[0012] Thus, each wire segment of the wire body wound on the peripheral side wall can be fixed, so that the wire body cannot move randomly on the peripheral side wall, which helps to improve the firmness of the fixed wire body.

[0013] In some embodiments, the first fixing mechanism and the second fixing mechanism are magnetically attracted.

[0014] Thus, the wire body and the peripheral side wall can be tightly adsorbed together, which helps to save the space required for storing the wire body.

[0015] In some embodiments, the second fixing mechanism comprises a magnetic layer wrapping the wire; the first fixing mechanism comprises a magnetic piece magnetically attracted to the magnetic layer to fix the wire on the peripheral side wall of the shell during winding of the wire.

[0016] Thus, the wire can be fixed on the magnetic attraction member of the circumferential side wall by the magnetic attraction layer, and the wire is not easy to be knotted under the influence of the magnetic attraction layer, so that the wire is easier to be stored, and the wire can be closely attached to the circumferential side wall, which helps to arrange the wire more regularly and closely, and helps to save the space required for storing the wire body. When in use, the wire can be fixed by pulling out, and when in storage, the wire can be automatically adsorbed by winding, which is convenient to use.

[0017] In some embodiments, the circumferential side wall comprises four outer side walls, and at least one first fixing mechanism is arranged at different heights of each outer side wall. When the wire is wound, the second fixing mechanism on the wire cooperates with the first fixing mechanism on the outer side wall to fix the wire on the circumferential side wall of the shell.

[0018] Since the first fixing mechanism is arranged on at least one outer side wall, the wire can be fixed on at least one outer side wall. Since the first fixing mechanism can be arranged at different heights of each outer side wall, the wire can be subjected to a more uniform force, which helps to improve the firmness and stability of the wire fixed on the outer side wall.

[0019] In some embodiments, the circumferential side wall is provided with a storage groove, and the wire can be wound in the storage groove and limited by the two side walls of the storage groove.

[0020] Thus, the wire can be protected and limited by the storage groove, so that the wire cannot move randomly on the circumferential side wall, which helps to improve the firmness of the wire storage. Moreover, the wire is contained in the storage groove, which helps to reduce the size of the electronic device accessory.

[0021] In some embodiments, the circumferential side wall is provided with a fixing groove for fixing the joint for storing the wire.

[0022] Thus, the joint can be contained in the fixing groove, and the fixing groove can protect the joint, which helps to further reduce the size of the electronic device accessory.

[0023] In some embodiments, a through hole is arranged at a position away from the fixing groove of the storage groove, and the wire passes through the through hole to be electrically connected with the charging assembly.

[0024] Thus, the wire can be wound layer by layer from one side of the storage groove to the other side, so that the wire can be wound in a more regular manner, which helps to reduce the probability of mutual interference and misplacement of the wire, and helps to save the space occupied by the wire.

[0043] In order to improve the convenience of people's daily life, various electronic devices have been produced. As one of the important accessories of electronic devices, the charger can charge the electronic products to maintain the endurance of the electronic products.

[0044] The charger generally includes a charging assembly and a wire material electrically connected to each other. The charging assembly can be electrically connected to an external power supply and convert current. The wire material provides the required current to the electronic device to realize charging. However, the wire material is generally long and flexible, and is prone to knotting and entanglement.

[0045] The present application provides an electronic device accessory, which comprises: a shell having a containing space, the shell comprising a circumferential side wall, the circumferential side wall being provided with a first fixing mechanism; a charging assembly, part of which is contained in the containing space, for electrically connecting an external power supply or an electronic device; and a wire material, at least part of which is contained in the containing space and electrically connected to the charging assembly, the wire material being provided with a second fixing mechanism corresponding to the first fixing mechanism at least in part, the wire material being capable of being wound on the shell, and the wire material being fixed on the circumferential side wall of the shell by the first fixing mechanism and the second fixing mechanism when the wire material is being wound and / or after being wound.

[0046] Since the circumferential side wall of the shell is provided with the first fixing mechanism, and the wire material is provided with the second fixing mechanism capable of cooperating with the first fixing mechanism, the wire material can be wound on the circumferential side wall, and the position of the wire material relative to the circumferential side wall is fixed by the first fixing mechanism and the second fixing mechanism, so as to realize the winding and arrangement of the wire material, which is simple in structure and convenient to use. Since the charging assembly is partially contained in the containing space, the shell can protect the part of the charging assembly located in the containing space.

[0047] The electronic device accessory can be used as a charger for converting current into a state meeting charging requirements. An electronic chip can be arranged in the electronic device accessory, so that the electronic device accessory can be used as a power bank.

[0048] The application will be described below with reference to the drawings.

Figure 4 A perspective view of an electronic device accessory provided by an embodiment of the application is shown. Figure 5 A perspective view of an electronic device accessory provided by an embodiment of the application is shown.

[0050] The application provides an electronic device accessory, as shown in the drawings. Figures 1 to 5 The electronic device accessory includes a housing 10 having a receiving space, the housing 10 including a peripheral side wall 11, the peripheral side wall 11 being provided with a first fixing mechanism 14; a charging assembly, part of which is accommodated in the receiving space, for electrically connecting an external power supply or an electronic device; and a wire 20, at least part of which is accommodated in the receiving space and electrically connected to the charging assembly, the wire 20 being provided, at least in part, with a second fixing mechanism 23 corresponding to the first fixing mechanism 14, the wire 20 being capable of being wound on the housing 10, and the wire 20 being fixed on the peripheral side wall 11 of the housing 10 by the first fixing mechanism 14 and the second fixing mechanism 23 when and / or after being wound.

[0051] The electronic device accessory includes a housing 10, a charging assembly, and a wire 20. The housing 10 has a receiving space, part of the charging assembly is located in the receiving space, and part of the wire 20 is located in the receiving space. The part of the charging assembly located in the receiving space and the part of the wire 20 located in the receiving space are electrically connected to each other. The housing 10 is provided with a first fixing mechanism 14, and the wire 20 is provided with a second fixing mechanism 23, and the first fixing mechanism 14 can cooperate with the second fixing mechanism 23 to achieve detachable connection.

[0052] The housing 10 includes a peripheral side wall 11. The peripheral side wall 11 surrounds the periphery of the receiving space. Exemplarily, the peripheral side wall 11 can be configured in a shape similar to a cylinder, a prism, or the like. The housing 10 further includes a first wall 12 and a second wall 13. The first wall 12 and the second wall 13 are respectively arranged on both sides of the axial direction X of the peripheral side wall, and the first wall 12 and the second wall 13 are opposite to each other. The peripheral side wall 11, the first wall 12, and the second wall 13 together enclose the receiving space. The axial direction X of the peripheral side wall is parallel to the extension direction of the peripheral side wall.

[0053] The first fixing mechanism 14 can be arranged on at least one of the peripheral side wall 11, the first wall 12 and the second wall. Alternatively, the first fixing mechanism 14 is arranged on the peripheral side wall 11 to facilitate the winding and fixing of the wire 20.

[0054] The wire 20 penetrates the housing 10, and a portion of the wire 20 is accommodated in the accommodation space, and another portion of the wire 20 is located outside the accommodation space. The second fixing mechanism 23 is arranged on the radial outer surface of the wire 20 at least in the portion of the wire 20. During the winding of the wire 20 on the housing 10, the second fixing mechanism 23 contacts and connects with the first fixing mechanism 14, so that the wire 20 can be fixed on the surface of the housing 10.

[0055] The first fixing mechanism 14 and the second fixing mechanism 23 can be connected by magnetic attraction, or by a magic tape, or by a clamping structure. The first fixing mechanism 14 and the second fixing mechanism 23 can be any connection mechanism that can achieve detachable connection, and the specific connection form of the first fixing mechanism 14 and the second fixing mechanism 23 is not limited in the present application.

[0056] The charging assembly penetrates the housing 10, and a portion of the charging assembly is accommodated in the accommodation space, and another portion of the charging assembly is located outside the accommodation space. The portion of the charging assembly located outside the accommodation space can be used for electrically connecting an external power source. The charging assembly can also be electrically connected to an external power source or an electronic device through the wire 20.

[0057] When the wire 20 needs to be accommodated, the wire 20 can be wound in a spiral shape on the peripheral side wall 11. During the winding, the second fixing mechanism 23 on the wire 20 contacts and connects with the first fixing mechanism 14 on the housing 10, so that the wire 20 is fixed relative to the housing 10. When charging is needed, the wire 20 can be pulled away from the peripheral side wall 11 and connected to an electronic device.

[0058] In the technical scheme of the embodiment of the present application, the first fixing mechanism 14 is arranged on the peripheral side wall 11 of the housing 10, and the second fixing mechanism 23 capable of cooperating with the first fixing mechanism 14 is arranged on the wire 20, so that the wire 20 can be wound on the peripheral side wall 11, and the position of the wire 20 relative to the peripheral side wall 11 is fixed through the first fixing mechanism 14 and the second fixing mechanism 23, thereby realizing the winding and arrangement of the wire 20, and the structure is simple and convenient to use. Since a portion of the charging assembly is accommodated in the accommodation space, the housing 10 can protect the portion of the charging assembly located in the accommodation space.

[0059] In some embodiments, continuing to refer to Figures 1 to 5The wire 20 includes a joint 21, and the second fixing mechanism 23 is arranged on the joint 21. When the wire 20 is wound on the circumferential wall 11, the first fixing mechanism and the second fixing mechanism 23 can face each other, and the wire 20 is fixed at the first fixing mechanism 14 of the shell 10 through the second fixing mechanism 23.

[0060] One end of the wire 20 is electrically connected to the charging assembly, and the other end of the wire 20 is provided with the joint 21, and the joint 21 is in conduction with the wire 20. The second fixing mechanism 23 is arranged on the joint 21. In the state that the wire 20 is wound on the circumferential wall 11, the first fixing mechanism and the second fixing mechanism 23 can face each other, and the wire 20 is fixed at the first fixing mechanism 14 of the shell 10 through the second fixing mechanism 23.

[0061] The joint 21 is used for electrically connecting an interface of an electronic device or an external power supply. Exemplarily, the interface of the joint 21 can be a USB interface, such as a type-A interface, a type-B interface, and a type-C interface, and the wire 20 can be electrically connected with the electronic device or the external power supply through the interface of the joint 21.

[0062] Since the joint 21 is arranged, the wire 20 can be electrically connected with the electronic device through the joint 21, so as to realize the transmission of current from the charging assembly to the electronic device; and the wire 20 can also be electrically connected with the external power supply through the joint 21, so as to realize the conversion or storage of current and the like. Since the second fixing mechanism 23 is arranged on the joint 21, after the wire 20 is wound, one end of the wire 20 can be fixed, so that the whole formed after the wire 20 is wound is fixed. Moreover, the second fixing mechanism 23 arranged on the joint 21 can fix the joint 21, so as to reduce the shaking of the joint 21 and help to reduce the wear degree of the joint 21.

[0063] In some embodiments, as shown in FIG. 1, Figure 4 The wire 20 includes a wire body 24, and at least part of the wire body 24 is provided with the second fixing mechanism 23. When the wire 20 is wound, the wire 20 is fixed on the circumferential wall 11 of the shell 10 through the second fixing mechanism 23 on the wire body 24 and the first fixing mechanism 14 on the circumferential wall 11.

[0064] The shell 10 includes the circumferential wall 11, and the circumferential wall 11 is arranged to form a containing space. The first fixing mechanism 14 is arranged on the circumferential wall 11, and the first fixing mechanism 14 can be arranged in a structure of head-to-tail connection around the circumferential wall 11, or the first fixing mechanism 14 can be arranged sporadically on the circumferential wall 11, or a single first fixing mechanism 14 can be arranged on any one side surface of the circumferential wall 11.

[0065] The wire 20 comprises a wire body 24, which is flexible and capable of being bent. A second fixing mechanism 23, such as a magic tape, a magnetic layer 22, or the like, can be arranged on the wire body 24 and capable of being bent with the wire body 24. Alternatively, a structure capable of being clamped, such as a male-female buckle, or the like, can be arranged on the wire body 24.

[0066] In some embodiments, as shown in Figs. 1-3, the wire 20 comprises a wire body 24 and a connector 21 electrically connected to each other, and the second fixing mechanism 23 is arranged on at least one of the wire body 24 and the connector 21. Figure 1 、 Figure 4 and Figure 5 The one end of the wire body 24 is electrically connected to the charging assembly, and the other end of the wire body 24 is provided with the connector 21, which is in conduction with the wire body 24. The second fixing mechanism 23 is arranged on the connector 21.

[0067] In order to improve the stability of the fixation of the wire 20, the second fixing mechanism 23 can be arranged on the wire body 24 and the connector 21, respectively. The second fixing mechanism 23 arranged on the wire body 24 and the second fixing mechanism 23 arranged on the connector 21 can adopt the same structure or different structures.

[0068] Thus, the wire body 24 is fixed on the peripheral side wall 11 by cooperation of the first fixing mechanism 14 and the second fixing mechanism 23, which is helpful for the regular winding and storage of the wire body 24.

[0069] In some embodiments, the wire body 24 comprises at least one wire segment, the length of the wire segment is equal to the circumference of the peripheral side wall 11, and at least one second fixing mechanism 23 is arranged on each wire segment. When the wire 20 is wound, the second fixing mechanism 23 on the wire segment cooperates with the first fixing mechanism 14 on the peripheral side wall 11 to fix the wire 20 on the peripheral side wall 11 of the shell 10.

[0070] The wire body 24 comprises at least one wire segment. In the state that the wire body 24 is wound on the peripheral side wall 11, the wire body 24 is spirally and layer by layer superposed. The position, through which the wire body 24 penetrates the peripheral side wall 11, can be regarded as the first end point of the wire segment, and the position, which is after the wire body 24 passes through the circumference of the peripheral side wall 11 from the first end point, can be regarded as the second end point of the wire segment. The wire body 24 comprises at least one wire segment, and the length of the wire body 24 is greater than the circumference of the peripheral side wall 11.

[0071] The second end point can be regarded as the starting point of the next wire segment, and the position, which is after the next wire segment passes through the circumference of the peripheral side wall 11 from the second end point, can be regarded as the third end point of the next wire segment, and the third end point can be regarded as the starting point of the next wire segment, and so on.

[0072] At least one second fixing mechanism 23 is arranged on each wire segment, and the first fixing mechanism 14 is arranged on the shell 10 according to the number of the second fixing mechanism 23 and the specific position of the second fixing mechanism 23 after the wire segment is wound on the circumferential side wall 11. The second fixing mechanism 23 can be arranged at one quarter of the wire segment; the second fixing mechanism 23 can also be arranged at one half of the wire segment; the second fixing mechanism 23 can also be arranged at one quarter of a part of the wire segment and at one half of another part of the wire segment.

[0073] Thus, each layer of the wire segment wound on the circumferential side wall 11 can be fixed, so that the wire body 24 cannot move randomly on the circumferential side wall 11, which helps to improve the firmness of the fixed wire body 24.

[0074] In some embodiments, as shown in Figure 2 and Figure 3 , the first fixing mechanism 14 and the second fixing mechanism 23 are matched by magnetic attraction.

[0075] The first fixing mechanism 14 can include one of a magnetic attraction layer 22 and a magnetic attraction piece, and the second fixing mechanism 23 can include one of the magnetic attraction layer 22 and the magnetic attraction piece. The magnetic attraction layer 22 refers to a surrounding layer made of a magnetic material, and the magnetic attraction piece refers to a component made of a magnetic material.

[0076] Exemplarily, the magnetic material includes ferrite, neodymium iron boron, samarium cobalt, aluminum nickel cobalt, etc.

[0077] In an alternative embodiment, one of the first fixing mechanism 14 and the second fixing mechanism 23 includes the magnetic attraction layer 22 or the magnetic attraction piece, and the other one of the first fixing mechanism 14 and the second fixing mechanism 23 includes a metal piece or a metal layer containing iron, cobalt and nickel.

[0078] Thus, the wire body 24 and the circumferential side wall 11 can be closely attracted together, which helps to save the space required for storing the wire body 24.

[0079] In some embodiments, continuing to refer to Figure 2 and Figure 3 , the second fixing mechanism 23 includes the magnetic attraction layer 22, and the magnetic attraction layer 22 wraps the wire 20; the first fixing mechanism 14 includes the magnetic attraction piece, and the magnetic attraction piece is matched with the magnetic attraction layer 22 by magnetic attraction, so as to fix the wire 20 on the circumferential side wall 11 of the shell 10 when the wire 20 is wound.

[0080] The first fixing mechanism 14 includes the magnetic attraction piece, and the second fixing mechanism 23 includes the magnetic attraction layer 22. The magnetic attraction piece is arranged on the circumferential side wall 11, and the magnetic attraction layer 22 wraps the wire 20. The magnetic attraction layer 22 and the magnetic attraction piece can be made of the same kind of magnetic material or different kinds of magnetic material.

[0081] The magnetic layer 22 is configured on the radial outer surface of the wire 20, and can be configured on the portion of the wire 20 located outside the accommodating space or on the whole wire 20. Specifically, the magnetic layer 22 is in the shape of a cylinder and is wrapped on the radial outer surface of the wire 20. The magnetic pole of the magnetic layer 22 located on one side of the surface of the wire 20 is the south pole, and the magnetic pole of the magnetic layer 22 located on the other side of the surface of the wire 20 is the north pole. The side of the magnetic layer 22 with the south pole is regarded as the south pole side, and the side of the magnetic layer 22 with the north pole is regarded as the north pole side.

[0082] When the wire 20 needs to be accommodated, the wire 20 can be spirally wound on the circumferential side wall 11. For the adjacent portions of the wire 20 in the axial direction X of the circumferential side wall, the south pole side and the north pole side face each other, so that the adjacent portions are automatically attracted to each other. Moreover, the wire 20 is fixed on the shell 10 under the attraction of the magnetic attraction member. When charging is needed, the wire 20 is pulled out from the circumferential side wall 11 and connected to the electronic device.

[0083] In this way, the wire 20 can be fixed on the magnetic attraction member of the circumferential side wall 11 through the magnetic layer 22, and the wire 20 is not easy to be knotted under the influence of the magnetic layer 22, so that the wire 20 is more easily accommodated, and the wire 20 can be closely attached to the circumferential side wall 11, which helps to arrange the wire 20 more regularly and closely and helps to save the space required for accommodating the wire body 24. When in use, the fixing can be released by pulling out, and when in storage, the wire 20 can be automatically attracted by winding, which is convenient to use.

[0084] In some embodiments, the circumferential side wall 11 includes four outer side walls, and at least one first fixing mechanism 14 is arranged at different heights of each outer side wall. When the wire 20 is wound, the second fixing mechanism 23 on the wire 20 cooperates with the first fixing mechanism 14 on the outer side wall to fix the wire 20 on the circumferential side wall 11 of the shell 10. Alternatively, at least one outer side wall of each outer side wall is provided with the first fixing mechanism 14, and when the wire 20 is wound, the second fixing mechanism 23 on the wire 20 cooperates with the first fixing mechanism 14 on the outer side wall to fix the wire 20 on the circumferential side wall 11 of the shell 10.

[0085] The circumferential side wall 11 can be configured in the shape of a cylinder, or in the shape of a prism, such as a triangular prism, a quadrangular prism, a pentagonal prism, etc. Hereinafter, the quadrangular prism is taken as an example for illustration. The circumferential side wall 11 includes four outer side walls, and the four outer side walls jointly form the accommodating space. The first fixing mechanism 14 is arranged on at least one outer side wall.

[0086] The wire body 24 comprises at least one wire segment, and each wire segment is provided with the second fixing mechanism 23, and the first fixing mechanism 14 is correspondingly arranged on the outer side wall. Specifically, the wire segments are stacked layer by layer along the axial direction X of the circumferential side wall, and the second fixing mechanism 23 on each layer of the wire segment is provided with the first fixing mechanism 14 with different heights (positions along the axial direction X of the circumferential side wall) on the outer side wall. Each first fixing mechanism 14 can be arranged on the same outer side wall; when the number of wire segments does not exceed the number of outer side walls, that is, when the number of wire segments does not exceed four, each first fixing mechanism 14 can also be arranged on different outer side walls respectively.

[0087] Optionally, in the state that the wire 20 is wound around the circumferential side wall 11, the second fixing mechanism 23 is arranged on the portion of each wire segment corresponding to each outer side wall, and the plurality of first fixing mechanisms 14 for fixing the wire segment are located at the same height.

[0088] In a specific embodiment, the second fixing mechanism 23 is arranged at one quarter or one half of each wire segment. After the wire 20 is wound around the circumferential side wall 11, the second fixing mechanism 23 is located on the same outer side wall on which the first fixing mechanism 14 is arranged. The wire 20 is fixed on the circumferential side wall 11 of the shell 10 by the cooperation of the second fixing mechanism 23 on the wire 20 and the first fixing mechanism 14 on the outer side wall.

[0089] In another specific embodiment, the number of wire segments is more than four, and the second fixing mechanism 23 is alternately arranged at the starting end, one quarter, two quarters, and three quarters of each wire segment, so that the second fixing mechanism 23 is arranged in a spiral shape. The first fixing mechanism 14 is arranged at different heights of each outer side wall corresponding to the second fixing mechanism 23. After the wire 20 is wound around the circumferential side wall 11, at least one outer side wall is opposite to at least two second fixing mechanisms 23, and at least two first fixing mechanisms 14 are correspondingly arranged on the outer side wall. The wire 20 is fixed on the circumferential side wall 11 of the shell 10 by the cooperation of the second fixing mechanism 23 on the wire 20 and the first fixing mechanism 14 on the outer side wall.

[0090] Since the first fixing mechanism 14 is arranged on at least one outer side wall, the wire 20 can be fixed on at least one outer side wall. Since the first fixing mechanism 14 can be arranged at different heights of each outer side wall, the wire 20 can be subjected to a more uniform force, which helps to improve the firmness and stability of the fixation of the wire 20 and the outer side wall.

[0091] In some embodiments, as shown in Figs. Figure 2 and Figure 4 The circumferential side wall 11 is provided with a receiving groove 111, and the wire 20 can be wound on the receiving groove 111 and limited by the two groove walls of the receiving groove 111.

[0092] The circumferential side wall 11 has different radial dimensions at the middle portion and the portions on both sides in the axial direction X of the circumferential side wall. Specifically, the surface of the circumferential side wall 11 is recessed in the direction of the accommodation space to form a receiving groove 111 in a ring shape connected head to tail around the surface of the circumferential side wall 11.

[0093] The wire 20 can be wound in the receiving groove 111, and the wire 20 is wrapped and accommodated in the receiving groove 111, and the two side groove walls of the receiving groove 111 can limit the movement of the wire 20 in the axial direction X of the circumferential side wall. The second fixing mechanism 23 can be arranged in the receiving groove 111.

[0094] Therefore, the wire 20 can be protected and limited by the receiving groove 111, so that the wire 20 cannot move randomly on the circumferential side wall 11, which helps to improve the firmness of the accommodation of the wire 20. Moreover, the wire 20 is accommodated in the receiving groove 111, which helps to reduce the size of the electronic equipment accessory.

[0095] In some embodiments, as shown in Figure 4 , the circumferential side wall 11 is provided with a fixing groove 112 for fixing the joint 21 of the wire 20.

[0096] In some embodiments, continuing to refer to Figure 1 , Figure 4 and Figure 5 , the circumferential side wall 11 is further provided with a fixing groove 112, a part of the receiving groove 111 extends in the direction away from itself to form the fixing groove 112, and the second magnetic attraction member is arranged in the fixing groove 112.

[0097] A part of the receiving groove 111 extends in the direction close to the first wall 12 or the second wall 13 to form the fixing groove 112 for accommodating the joint 21. The fixing groove 112 can be parallel to the receiving groove 111, or can be inclined relative to the receiving groove 111. The fixing groove 112 and the receiving groove 111 are in communication with each other. The second fixing mechanism 23 can be arranged in the fixing groove 112.

[0098] Therefore, the joint 21 can be accommodated in the fixing groove 112, and the fixing groove 112 can protect the joint 21, which helps to further reduce the size of the electronic equipment accessory.

[0099] In some embodiments, a through hole is arranged in the receiving groove 111 away from the fixing groove 112, and the wire 20 passes through the through hole to be electrically connected with the charging assembly.

[0100] A through hole is arranged in the circumferential side wall 11, the accommodation space can be in communication with the outside through the through hole, and the wire 20 passes through the through hole. The part of the wire 20 located in the accommodation space is electrically connected with the charging assembly.

[0101] The through hole can be arranged in the groove bottom of the receiving groove 111, or can be arranged in the groove wall of the receiving groove 111. The through hole is located at a position of the receiving groove 111 away from the fixing groove 112.

[0102] Thus, the wire 20 can be wound layer by layer from one side of the receiving groove 111 to the other side of the receiving groove 111, and the joint 21 reaches the position of the fixing groove 112, so that the wire 20 can be wound in a more regular manner, which helps to reduce the probability of mutual interference and misplacement of the wire 20, and helps to save the space occupied by the wire 20.

[0103] The charging assembly can be electrically connected to the external power source by the components thereof, or can be electrically connected to the external power source or the electronic device by the wire 20.

[0104] In an optional embodiment, the charging assembly comprises the pin 31 and a circuit board, the circuit board is accommodated in the accommodation space, the circuit board is electrically connected to the pin 31 and the wire 20 respectively, and the pin 31 is arranged on the first wall 12 adjacent to the peripheral side wall 11 of the shell 10, and the pin 31 is used for electrically connecting to the external power source.

[0105] The pin 31 can be any one of a 2-core power pin, a 3-core power pin, and a multi-core power pin.

[0106] Further, the pin 31 is rotationally connected to the first wall 12. A groove recessed towards the accommodation space is formed on the first wall 12, and the pin 31 is rotationally connected to the groove. When the pin 31 is rotated to an angle at which the extension direction of the pin 31 is parallel to the extension direction of the first wall 12, the pin 31 is accommodated in the groove. When the pin 31 is rotated to an angle at which the extension direction of the pin 31 is perpendicular to the extension direction of the first wall 12, the pin 31 is exposed from the groove and can be inserted into the external power source.

[0107] Thus, the circuit board is electrically connected to the external power source by the pin 31, and the wire 20 can supply the current converted by the circuit board to the electronic device to realize charging.

[0108] In some embodiments, the charging assembly further comprises an electric core electrically connected to the circuit board. The electric core is located in the accommodation space and is used for storing and providing electric energy. The electric core can be a secondary battery, which refers to a battery that can be activated by charging after the battery monomer is discharged. The electronic device accessory is provided with the electric core, so that the electronic device accessory can be used as a portable power bank.

[0109] Thus, without connecting the external power source, the electric core itself can store and provide electric energy, and when the electronic device needs to be charged, it only needs to carry the electronic device accessory, that is, plug and charge, which is convenient to use.

[0110] In some embodiments, as Figure 4 and Figure 5As shown, the electronic device accessory further comprises a socket 50, the charging assembly comprises a circuit board, and the socket 50 is arranged on the second wall 13 of the shell 10 adjacent to the peripheral side wall 11, and the socket 50 is electrically connected to the circuit board.

[0111] In a specific embodiment, the pin 31 is arranged on the first wall 12, and the socket 50 is arranged on the second wall 13, and the second wall 13 and the first wall 12 are opposite to each other. The socket 50 is electrically connected to the charging assembly, and the user can connect the charger of the electronic device accessory to the socket 50, and the charging assembly charges the electronic device through the socket 50.

[0112] The socket 50 can be provided in multiple, and the multiple sockets 50 can adopt the same interface or different interfaces. The interface can be a USB interface, such as a type-A interface, a type-B interface, and a type-C interface.

[0113] In some embodiments, as shown in Figure 2 , Figure 4 and Figure 5 , a switch 40 is arranged on the shell 10, the switch 40 is electrically connected to the circuit board, and the switch 40 is used to control the on-off of the circuit.

[0114] The switch 40 can be arranged on the peripheral side wall 11, and the circuit board, the battery and the switch 40 are electrically connected to each other, when the switch 40 is turned on, the three form a path, and when the switch 40 is turned off, the circuit is disconnected.

[0115] Thus, when not in use, the battery is powered off, which helps to reduce the risk of accidental electric shock.

[0116] The electronic device accessory of the present application, because of the wire 20 and the battery, the user does not need to carry an extra wire 20 when going out, and only needs to carry an electronic device accessory to solve the charging problem. Because the wire 20 is partially located outside the accommodation space, the wire 20 can be wound outside the shell 10, the storage is simple, and the internal space of the shell 10 can be saved. The user can operate the electronic device with one hand, and easily stretch the length of the wire 20 to charge the electronic device with the other hand, improving the convenience of use.
