[0048] With reference to the drawings, the technical solutions in the embodiments of the present application will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0049] It should be noted that if the embodiments of the present application involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative positional relationship, movement condition, etc. between components in a certain posture, and if the certain posture changes, the directional indications also change accordingly.

[0050] In addition, if the embodiments of the present application involve descriptions such as “first”, “second”, etc., the descriptions of “first”, “second”, etc. are only for description purposes, and cannot be understood as indicating or implying the relative importance of the indicated technical features or implicitly indicating the number of the indicated technical features. Therefore, the features limited by “first”, “second” can explicitly or implicitly include at least one of the features. In addition, if “and / or”, “and / or” or “and / or” appears in the entire text, it means that the three parallel schemes include A scheme, or B scheme, or A and B schemes are satisfied at the same time. In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the realization of a person of ordinary skill in the art, and when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, nor is it within the scope of protection claimed by the present application.

[0051] In the related art, the mobile phone support can support the mobile phone, which is convenient for users to watch movies, brush videos and other entertainment, but when the mobile phone support is adsorbed on the mobile phone by the magnet, if the number of magnets arranged is less, it will lead to poor adsorption force, and if the number of magnets is increased, it will increase the weight of the mobile phone support, and is not conducive to the miniaturization design of the mobile phone support.

[0052] In view of this, see Figures 1-12The embodiment of the utility model provides a kind of accessory 10 of enhancing magnetic attraction force, for electronic equipment 200, this electronic equipment 200 includes but is not limited to: mobile phone, tablet computer and electronic reader.For example, electronic equipment 200 is mobile phone, accessory 10 specifically can be mobile phone support, mobile phone shell, mobile phone ornament, mobile hard disk, lens filter etc.

[0053] Support 100 includes magnetic attraction component 110, see Figure 11 Magnetic attraction component 110 includes magnetizing piece 112 and magnetic material layer 113 stacked with each other along thickness direction X.Magnetic flux density of magnetizing piece 112 is greater than that of magnetic material layer 113.Magnetizing piece 112 is magnet after magnetization, and magnetic material layer 113 only has lower magnetic flux density compared with magnetizing piece 112, so that magnetic material layer 113 can be iron sheet or other parts made of magnetic material, for example, the material of magnetic material layer 113 can be any one of iron, nickel, iron-nickel alloy.Magnetizing piece 112 is located between magnetic material layer 113 and electronic equipment 200 along thickness direction X, and the magnetic flux density of the side of magnetic attraction component 110 close to electronic equipment 200 is greater than that of the side of magnetic attraction component 110 away from electronic equipment 200.

[0054] According to the above arrangement, if the magnetic assembly 110 is only provided with the magnetic member 112 and is attracted to the electronic device 200 by the magnetic member 112, the magnetic force lines on both sides of the magnetic assembly 110 in the thickness direction X are relatively uniform, and the magnetic assembly 110 relies only on the magnetic force on one side to play a magnetic attraction role, which makes the magnetic force of the magnetic assembly 110 not be used efficiently. Therefore, according to the scheme of the present application, if the magnetic material layer 113 is laid on the side of the magnetic member 112 close to the electronic device 200, a reflection effect is achieved, the distribution of the magnetic force lines is changed, and more magnetic force lines are directed towards the side of the electronic device 200, thereby increasing the magnetic attraction force between the support 100 and the electronic device 200. Specifically, the magnetic material layer 113 generates its own magnetic field after being magnetized, and this magnetic field is superimposed with the original magnetic field of the magnetic member 112, thereby enhancing the original magnetic field of the magnetic member 112. At this time, the distribution of the magnetic lines of force changes, for example, in the area close to the magnetic material layer 113, the magnetic lines of force are more dense, and a part of the magnetic lines of force pass through the inside of the magnetic material layer 113, pass out from one end of the magnetic material layer 113, and then return to the magnetic member 112 or extend to the surrounding space. This changes the range and shape of the entire magnetic field.

[0055] It can be seen that the support 100 of the present application includes the magnetic assembly 110, which includes the magnetic member 112 and the magnetic material layer 113 stacked along the thickness direction X. The magnetic flux density of the magnetic member 112 is greater than that of the magnetic material layer 113, the magnetic member 112 is located between the magnetic material layer 113 and the electronic device 200 along the thickness direction X, and the magnetic flux density on the side of the magnetic assembly 110 close to the electronic device 200 is greater than that on the side of the magnetic assembly 110 away from the electronic device 200. Compared with the arrangement in the related art in which only a magnet is arranged to form an attraction effect, in the scheme of the present application, the magnetic field superposition effect of the magnetic member 112 and the magnetic material layer 113 can change the distribution of the magnetic force lines, so that the magnetic lines of force on the side of the magnetic assembly 110 close to the electronic device 200 are more dense, thereby making the magnetic attraction effect of the magnetic assembly 110 better. Therefore, the support 100 of the present application can have a better magnetic attraction effect.

[0056] Referring to Figures 1-3In some embodiments, the support assembly 120 comprises a support piece 121 and a folding piece 122, both of which are adapted to support the electronic device 200. The support assembly 120 is connected to the magnetic assembly 110, and is configured to be rotatable relative to the magnetic assembly 110, and is adapted to support the electronic device 200. The support piece 121 is configured to be rotatable relative to the magnetic assembly 110 about an axis perpendicular to the thickness direction X, so as to switch the support piece 121 between a first folded state and a first support state. The folding piece 122 comprises a first folding portion 1221 and a second folding portion 1222, which are configured to be reversibly folded relative to each other about an axis perpendicular to the thickness direction X, so as to switch the folding piece 122 between a second folded state and a second support state. It can be understood that both the support piece 121 and the folding piece 122 are used to support the electronic device 200, but the difference is that the support piece 121 supports the electronic device 200 by rotating to a certain position, while the folding piece 122 supports the electronic device 200 by reversibly folding the first folding portion 1221 and the second folding portion 1222 to a certain position. Therefore, the support forms of the support piece 121 and the folding piece 122 can be different, and the applicable scenarios can also be different. Meanwhile, the scenarios in which the support 100 supports the electronic device 200 described in the present application include but are not limited to: supporting on a table, forming a stable holding effect on the electronic device 200 together with the user's hand through the structure of the support 100, or hanging the electronic device 200 on the user's hand or other objects through the structure (such as a ring structure) of the support 100. For example, see Figures 1-3 In some embodiments, the support piece 121 can serve as a ring-shaped support 100, and in the first support state, the support piece 121 is reversibly folded to protrude from the electronic device 200, and the ring-shaped structure of the support piece 121 itself can be adapted for the user to insert a finger and stably hold (or lift) the electronic device 200. In addition, the folding piece 122 can serve as a disc-shaped support 100, and in the first support state, the side of the folding piece 122 away from the electronic device 200 along the thickness direction X can have a disc-shaped structure, which can facilitate the user's fingers to abut against or facilitate the support 100 to be adsorbed to other structures. The diameter of the side of the folding piece 122 close to the electronic device 200 can be smaller than that of the disc-shaped structure, so as to facilitate the structure at this position to be clamped by the user's two fingers. In addition, in the first support state, the support effect of the folding piece 122 can also be similar to that of the support piece 121, and the electronic device 200 can also be supported on a table.

[0057] According to the above arrangement, in particular, see Figures 1-3 and Figures 8-10In the first folded state, the first connecting structure 1111 and the second connecting structure 1211 are clamped to limit the displacement of the support 121 relative to the base 111 along the thickness direction X, and / or, in the second folded state, the third connecting structure 1112 and the fourth connecting structure 1223 are clamped to limit the displacement of the folding piece 122 relative to the base 111 along the thickness direction X. It can be understood that, on the one hand, the relative position of the base 111 and the support 121 can be fixed in the first folded state through the clamping action between the first connecting structure 1111 and the second connecting structure 1211; on the other hand, the relative position of the base 111 and the folding piece 122 can be fixed in the second folded state through the clamping action between the third connecting structure 1112 and the fourth connecting structure 1223. In combination with the above description of the support forms of the support 121 and the folding piece 122, when the user needs one of the support 121 and the folding piece 122 to play a supporting role, the other should be kept in the first folded state / second folded state, otherwise it will interfere with the supporting effect or affect the user experience, so that the clamping action of the above two aspects can respectively fix the support 121 and the folding piece 122 in the first folded state and the second folded state, so as to avoid the mutual interference between the support 121 and the folding piece 122. Compared with the design of the related art in which each support structure is independently provided without a positioning structure, in the scheme of the present application, on the one hand, the relative position of the base 111 and the support 121 can be fixed in the first folded state through the clamping action between the first connecting structure 1111 of the base 111 and the second connecting structure 1211 of the support 121; on the other hand, the relative position of the base 111 and the folding piece 122 can be fixed in the second folded state through the clamping action between the third connecting structure 1112 of the base 111 and the fourth connecting structure 1223 of the folding piece 122. Therefore, the bracket 100 of the present application can stabilize the folded state of the support 121 or the folding piece 122, which is conducive to avoiding the mutual interference between the support 121 and the folding piece 122.

[0058] Referring to Figures 4-5In some embodiments, the magnetic attraction assembly 110 includes a first magnetic member 1121 and a second magnetic member 1122. The magnetic attraction member 112 described in the present application refers to the first magnetic member 1121 and / or the second magnetic member 1122. The first magnetic member 1121 and the second magnetic member 1122 are arranged in a spaced-apart manner along an axis parallel to the thickness direction X. The ends of the first magnetic member 1121 and the second magnetic member 1122 along the circumferential direction R can be fixedly connected to or abut each other, and the spaced-apart arrangement between the first magnetic member 1121 and the second magnetic member 1122 can collectively form a complete annular structure or a ring structure with a gap. The annular structure described in the present application includes a circular ring, a rectangular ring, and any other annular structure.

[0059] According to the above arrangement, in particular, referring to Figures 4-5 , along the width direction Y perpendicular to the thickness direction X and the circumferential direction R, the size of the first magnetic member 1121 is smaller than the size of the second magnetic member 1122. The first magnetic member 1121 and the second magnetic member 1122 define an avoidance slot 1123. It can be understood that, due to the size of the first magnetic member 1121 along the width direction Y being smaller than the size of the second magnetic member 1122 along the width direction Y, the difference in the width of the first magnetic member 1121 and the second magnetic member 1122 forms the avoidance slot 1123, and at the same time, in order to effectively utilize the space of the avoidance slot 1123, at least part of the support assembly 120 is located in the avoidance slot 1123. Through the above arrangement, the support assembly 120 can be arranged in the space of the avoidance slot 1123, which is beneficial to increase the design size of the support assembly 120, and further improve the rotation structure strength of the support assembly 120 and the overall support strength of the support assembly 120. At the same time, the avoidance slot 1123 is formed due to the reduction of the size of the first magnetic member 1121 along the thickness direction X, and the number of magnetic members is not reduced, so that the arrangement has little effect on the overall magnetic attraction effect of the magnetic attraction assembly 110. Under the premise that the overall size of the support 100 does not change, compared with the design of reducing the size of the rotation structure or reducing the number of magnetic members in the related art to avoid interference between the rotation structure and the magnetic member, the present application forms the avoidance slot 1123 by reducing the size of the first magnetic member 1121 along the thickness direction X, and at least part of the support assembly 120 is located in the avoidance slot 1123, which can avoid the influence on the rotation structure strength and the overall support strength of the support assembly 120, and has little effect on the magnetic attraction effect. Therefore, the support 100 of the present application is more convenient for the spatial arrangement of the support assembly 120, which is beneficial to guarantee the rotation structure strength of the support assembly 120 and the overall support strength of the support assembly 120.

[0060] For the distribution form of the magnetic attraction member 112 and the magnetic material layer 113, refer to Figure 6In one aspect, in some embodiments, the magnetic member 112 has a fan ring shape in the orthogonal projection in the plane perpendicular to the thickness direction X. In another aspect, in some embodiments, the magnetic material layer 113 has a fan ring shape in the orthogonal projection in the plane perpendicular to the thickness direction X. The above two aspects can facilitate the magnetic member 112 and the magnetic material layer 113 to extend in a ring shape along the circumferential direction R around the thickness direction X. Further, in one aspect, in some embodiments, the magnetic member 112 is provided in a plurality of numbers and distributed around the axis parallel to the thickness direction X. In another aspect, in some embodiments, the magnetic material layer 113 is provided in a plurality of numbers and distributed around the axis parallel to the thickness direction X. In the above two aspects, the magnetic member 112 and the magnetic material layer 113 are provided in a plurality of numbers and distributed around, which can make the arrangement of the magnetic member 112 and the magnetic material layer 113 more flexible and facilitate efficient use of the arrangement space along the circumferential direction R.

[0061] In order to achieve better magnetic attraction effect, in some embodiments, the material of the magnetic material layer 113 is one of iron and iron-nickel alloy.

[0062] The thickness dimension of the magnetic member 112 and the magnetic material layer 113 can be defined to control the magnetic field distribution around the magnetic assembly 110, so that the magnetic field superposition of the magnetic member 112 and the magnetic material layer 113 is better. Here, the dimension of the magnetic member 112 along the thickness direction X is defined as W1, and the dimension of the magnetic material layer 113 along the thickness direction X is defined as W2. Thus, in some embodiments, 0.1mm≤W1≤0.5mm, 2mm≤W2≤2.4mm, and exemplarily, W1 can take one of 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, and W2 can take one of 2mm, 2.1mm, 2.2mm, 2.3mm, 2.4mm. In some embodiments, 0.5mm≤W1≤0.9mm, 1.6mm≤W2≤2mm, and exemplarily, W1 can take one of 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, and W2 can take one of 1.6mm, 1.7mm, 1.8mm, 1.9mm, 2mm. In some embodiments, W1+W2=2.5mm, and in one implementation, W1 takes 0.3mm and W2 takes 2.2mm. In another implementation, W1 takes 0.7mm and W2 takes 1.8mm. It has been tested that in this case, the magnetic assembly 110 can generate a larger magnetic attraction force on the electronic device 200.

[0063] When the thickness of the support 100 is large, the magnetic attraction and the magnetic charging effect are affected. When the thickness of the support 100 is small, the arrangement of the magnetic attraction member 112 and the magnetic material layer 113 is limited, and the magnetic force is weak. Therefore, the overall thickness size of the support 100 can be limited, so that the magnetic attraction member 112 and the magnetic material layer 113 are arranged conveniently, and the magnetic attraction effect is better. In some embodiments, the size of the support 100 along the thickness direction X is D, and satisfies: 3.5mm≤D≤3.8mm. For example, D can be one of 3.5mm, 3.6mm, 3.7mm, and 3.8mm.

[0064] In order to arrange the magnetic attraction member 112 more conveniently, referring to Figures 4-5 In some embodiments, the magnetic attraction assembly 110 further includes a base 111, and the base 111 defines a containing groove 1116 recessed towards one side along the thickness direction X. The magnetic attraction member 112 and the magnetic material layer 113 can be located in the containing groove 1116. The first magnetic member 1121 and the second magnetic member 1122 can be located in the containing groove 1116. The above arrangement makes the magnetic attraction member 112 and the magnetic material layer 113 more convenient to arrange, and does not need to be stacked on the base 111 to arrange the magnetic attraction member 112 and the magnetic material layer 113, thereby reducing the overall height space occupied by the support 100. Further, corresponding to the size difference of the first magnetic member 1121 and the second magnetic member 1122 along the width direction Y, in some embodiments, the containing groove 1116 includes a first groove 11161 and a second groove 11162, the first groove 11161 contains the first magnetic member 1121, and the second groove 11162 contains the second magnetic member 1122. Along the width direction Y, the size of the first groove 11161 is smaller than the size of the second groove 11162. The above arrangement makes the size of the containing groove 1116 along the width direction Y and the size of the first magnetic member 1121 and the second magnetic member 1122 along the width direction Y adapt to each other, so that the first magnetic member 1121 and the second magnetic member 1122 can be positioned by the groove surface of the containing groove 1116, and the influence of the installation shaking of the first magnetic member 1121 and the second magnetic member 1122 on the magnetic attraction effect is reduced.

[0065] Referring to Figures 4-5In some embodiments, the base 111 defines a rotating groove 1117 recessed on one side in the thickness direction X, and based on the support 121, the support end 1213 and the rotating seat 123 defined in the foregoing embodiments, in order to facilitate the cooperation and connection between the support assembly 120 and the rotating groove 1117, the support 121 comprises a support ring 124 and a rotating shaft 125 which are integrally connected with each other, so that after the rotating shaft 125 is arranged through the rotating seat 123, the rotating shaft 125 and the rotating seat 123 can jointly extend into the rotating groove 1117, so that the installation operation is more convenient. Further, in some embodiments, the support ring 124 comprises a first support end 1213 and a second support end 1213 which are arranged at intervals, and the first support end 1213 and the second support end 1213 are both at least partially located in the avoiding groove 1123, the rotating shaft 125 is arranged through the avoiding groove 1123, and along the circumferential direction R around the thickness direction X, one end of the rotating shaft 125 is arranged out of the through hole and connected with the first support end 1213, and the other end of the rotating shaft 125 is arranged out of the through hole and connected with the second support end 1213.

[0066] Referring to Figures 4-5 In some embodiments, along the width direction Y, the end of the first magnetic member 1121 away from the axis is a first end 11211, the end of the second magnetic member 1122 away from the axis is a second end 11221, and the first end 11211 and the second end 11221 define an avoiding groove 1123 therebetween. The above arrangement makes the avoiding groove 1123 jointly defined by the outer side of the first magnetic member 1121 and the outer side of the second magnetic member 1122, at this time, the support assembly 120 can be sleeved on the outer side of the magnetic attraction assembly 110. On the contrary, in other embodiments, along the width direction Y, the end of the first magnetic member 1121 close to the axis is a first end 11211, the end of the second magnetic member 1122 close to the axis is a second end 11221, and the first end 11211 and the second end 11221 define an avoiding groove 1123 therebetween. The above arrangement makes the avoiding groove 1123 jointly defined by the inner side of the first magnetic member 1121 and the inner side of the second magnetic member 1122, at this time, the support assembly 120 can be sleeved on the inner side of the magnetic attraction assembly 110. For the convenience of description, the following will take the embodiment that the avoiding groove 1123 is jointly defined by the outer side of the first magnetic member 1121 and the outer side of the second magnetic member 1122 as an example.

[0067] Referring to Figures 4-5In some embodiments, the support assembly 120 comprises a rotating base 123 fixedly connected with the magnetic assembly 110 and a support 121 rotatably connected with the rotating base 123. More specifically, in some embodiments, the support assembly 120 comprises a rotating base 123 defining a through hole and a support 121 comprising a support ring 124 and a rotating shaft 125 connected with each other, the rotating shaft 125 penetrating the through hole, so that the rotating base 123 can serve as a rotating support of the support 121. In some embodiments, the first magnetic members 1121 are multiple in number, the rotating base 123 has a third end 1231 and a fourth end 1232, at least one first magnetic member 1121 is located between the third end 1231 and the second magnetic member 1122, and at least one first magnetic member 1121 is located between the fourth end 1232 and the second magnetic member 1122. It can be understood that, by arranging the adjacent first magnetic members 1121 and the second magnetic members 1122 on both sides of the rotating base 123 along the circumferential direction R, the both sides of the rotating base 123 can form the avoiding grooves 1123, thereby making the avoiding grooves 1123 have a better avoiding effect on the arrangement of the rotating base 123 or the support 121.

[0068] Based on the above arrangement, further, referring to Figure 6 In some embodiments, the first magnetic members 1121 and the second magnetic members 1122 are multiple in number, each first magnetic member 1121 and each second magnetic member 1122 are separately arranged, and are distributed along the circumferential direction R around the thickness direction X. By arranging the first magnetic members 1121 and the second magnetic members 1122 to be multiple and separately arranged, the arrangement of the first magnetic members 1121 and the second magnetic members 1122 can be more flexible, which is conducive to efficient use of the arrangement space along the circumferential direction R. Meanwhile, along the circumferential direction R, the size of each first magnetic member 1121 can be smaller than the size of each second magnetic member 1122. The above arrangement can reduce the influence of the smaller width size of the first magnetic members 1121 on the overall magnetic effect of the magnetic assembly 110, and make the first magnetic members 1121 more convenient to replace. Users can flexibly replace the first magnetic members 1121 of different sizes according to needs.

[0069] For the specific arrangement form of the first magnetic members 1121 and the second magnetic members 1122, referring to Figure 6 In some embodiments, along the circumferential direction R around the thickness direction X, the end of the first magnetic member 1121 and the end of the second magnetic member 1122 abut each other. The first magnetic members 1121 and the second magnetic members 1122 are separately arranged, which makes the arrangement of the two more flexible. Meanwhile, the abutment of the two can reduce the gap of the two along the circumferential direction R, so that the arrangement of the first magnetic members 1121 and the second magnetic members 1122 along the circumferential direction R is more dense, thereby having a better magnetic attraction effect. Alternatively, referring toFigure 4 In some embodiments, the first magnetic member 1121 and the second magnetic member 1122 are integrally connected. The above arrangement makes the first magnetic member 1121 and the second magnetic member 1122 have lower manufacturing cost, faster installation, and better magnetic attraction effect.

[0070] For the specific arrangement of the support member 121, see Figure 4 or Figure 6 In some embodiments, the support member 121 includes oppositely arranged rotating end 1212 and support end 1213. The rotating end 1212 is rotatably connected to the base 111. In the first folding state, the support member 121 is sleeved outside the base 111. In the first supporting state, the support member 121 gradually extends away from the side of the electronic device 200 in the direction from the rotating end 1212 to the support end 1213. It can be understood that the rotating end 1212 is one end of the support member 121 rotatably connected to the base 111, and the support end 1213 is one end that mainly supports and serves as a rotating free end. It should be noted that the rotating end 1212 and the support end 1213 can be two regions of an integrally connected part.

[0071] Based on the support member 121, the rotating end 1212, and the rotating seat 123 defined in the foregoing embodiments, see Figures 4-5 In some embodiments, in the thickness direction X, the size of the rotating end 1212 is greater than the average size of the support member 121. It can be understood that since the rotating end 1212 is the part of the support member 121 used for rotation connection, the larger size of this part makes the rotating structure of the support member 121 have higher strength. At the same time, the larger size of the rotating end 1212 can also correspond to the avoiding groove 1123, so that the avoiding effect of the avoiding groove 1123 is fully utilized.

[0072] Further, in some embodiments, the material of the rotating seat 123 is metal, so that the rotating seat 123 can be magnetized. The magnetic flux density of the rotating seat 123 can be less than the magnetic flux density of the first magnetic member 1121 and the second magnetic member 1122. Through the above arrangement, the rotating seat 123 can be magnetized by the first magnetic member 1121 and the second magnetic member 1122, so that the rotating seat 123 also has magnetism, thereby replacing the first magnetic member 1121 and the second magnetic member 1122 in the position where the first magnetic member 1121 and the second magnetic member 1122 are not arranged, and playing a similar magnetic attraction role, so that the overall magnetic attraction effect of the magnetic attraction assembly 110 is better.

[0073] Based on the rotating end 1212 and the support end 1213 defined above, for the specific structure of the first connecting structure 1111 and the second connecting structure 1211, see Figure 2In some embodiments, the support end 1213 is provided with a second connecting structure 1211, and the second connecting structure 1211 defines a first clamping groove 12111. In the first folding state, the first connecting structure 1111 abuts the groove surface of the first clamping groove 12111 along the thickness direction X. It can be understood that the movement of the support 121 along the thickness direction X can be limited by the abutting cooperation of the first connecting structure 1111 and the first clamping groove 12111. More specifically, in some embodiments, the side of the first connecting structure 1111 away from the electronic device 200 can abut the first clamping groove 12111, thereby limiting the movement of the support 121 in the direction approaching the electronic device 200; in other embodiments, the side of the first connecting structure 1111 close to the electronic device 200 can abut the first clamping groove 12111, thereby limiting the movement of the support 121 in the direction away from the electronic device 200. Conversely, in other embodiments, the first connecting structure 1111 of the base 111 can be provided with a groove structure, and in the first folding state, the second connecting structure 1211 of the support 121 abuts the groove structure of the first connecting structure 1111 along the thickness direction X, thereby also forming the effect of abutting positioning.

[0074] For the specific structure of the first connecting structure 1111 and the second connecting structure 1211, see Figure 3 and Figure 10 In some embodiments, the third connecting structure 1112 defines an annular groove 11121 extending along the circumferential direction R around the thickness direction X, and the fourth connecting structure 1223 extends in a ring shape along the circumferential direction R, and the fourth connecting structure 1223 extends into the annular groove 11121. It can be understood that in the second folding state, the folding piece 122 is contracted, and at this time the fourth connecting structure 1223 extends into the annular groove 11121, thereby forming a clamping cooperation, and the folding piece 122 is received and positioned by the annular groove 11121. According to the needs, the cross-sectional shape of the annular groove 11121 can be a circular ring, a rectangular ring, or any other suitable annular shape. At the same time, in order to achieve a better clamping positioning effect, the first folding part 1221 is provided with the fourth connecting structure 1223, and in some embodiments, the first folding part 1221 and the second folding part 1222 are clamped in the second folding state. Through the above arrangement, the relative shaking of the first folding part 1221 and the second folding part 1222 can be avoided, further ensuring the stability of the folding piece 122 in this state.

[0075] Further, see Figure 3In some embodiments, the fourth connecting structure 1223 is in sliding connection with the annular groove 11121, so that the folding piece 122 can rotate relative to the base 111 about an axis parallel to the thickness direction X. Through the above arrangement, the folding piece 122 can rotate in the annular groove 11121 about an axis parallel to the thickness direction X, so as to realize the angle adjustment of the folding piece 122.

[0076] Referring to Figure 8 and Figure 10 In some embodiments, the base 111 extends along the circumferential direction R to form a containing cavity 1113, and the containing cavity 1113 includes the annular groove 11121. In the first folded state, the supporting piece 121 is sleeved outside the base 111, and in the second folded state, the folding piece 122 is located in the containing cavity 1113.

[0077] In order to limit the rotation movement of the folding piece 122 relative to the base 111 about an axis parallel to the thickness direction X, referring to Figure 10 In some embodiments, the base 111 includes a clamping protrusion 1118, and the first folding part 1221 defines a second clamping groove 12211. In the second folded state, the clamping protrusion 1118 extends into the second clamping groove 12211, so as to limit the displacement of the folding piece 122 relative to the base 111 along the circumferential direction R, wherein the circumferential direction R surrounds the thickness direction X. In combination with the above-mentioned embodiment in which the fourth connecting structure 1223 is in sliding connection with the annular groove 11121, in some embodiments, in the second supporting state, the clamping protrusion 1118 does not limit the second clamping groove 12211, so that the folding piece 122 can rotate relative to the base 111 about an axis parallel to the thickness direction X. In the second folded state, through the clamping cooperation of the clamping protrusion 1118 and the second clamping groove 12211, the rotation movement of the folding piece 122 can be limited.

[0078] In order to achieve better space utilization in the folded state, referring to Figure 8 On the one hand, in some embodiments, the base 111 has an upper end surface 1114 and a lower end surface 1115 arranged opposite along the thickness direction X. In the first folded state, the supporting piece 121 is located between the upper end surface 1114 and the lower end surface 1115. Similarly, on the other hand, in some embodiments, based on the above-mentioned definition of the upper end surface 1114 and the lower end surface 1115, in the second folded state, the folding piece 122 is located between the upper end surface 1114 and the lower end surface 1115. It can be understood that the above-mentioned two aspects can respectively reduce the height space occupied by the supporting piece 121 in the first folded state and the height space occupied by the folding piece 122 in the second folded state.

[0079] The above merely preferred embodiments of the present application, and not therefore limit the patent scope of the present application, all in the application of the application concept, using the application specification and drawing content of the equivalent structure transformation, or direct / indirect application in other related technical fields are included in the patent protection scope of the present application.
