Description

Technical Field

[0001] The present application relates to the technical field of electronic equipment accessories, and in particular to a rotating connection structure, a bracket and an electronic equipment accessory. Background Art

[0002] In the current field of electronic equipment accessories technology, there is a wide demand for brackets or protective shells with brackets. For example, portable electronic devices such as smart phones, tablet computers, and mobile power supplies can be installed with brackets or protective shells with brackets. The pursuit and realization of thinness and lightness of the above-mentioned electronic devices in recent years have also made the corresponding electronic equipment accessories present a trend of meeting thinness and lightness. In the prior art, the bracket structure generally includes a connecting part connected to the electronic device or the electronic equipment accessory, and a supporting part for supporting, and includes a rotating shaft that rotatably connects the connecting part and the supporting part. Therefore, the rotating shaft itself is a cylindrical structure, and the supporting part and the connecting part also need to extend the damping structure to surround the rotating shaft, so as to realize the rotation and positioning of the supporting part relative to the connecting part. In the above-mentioned bracket technical solution using the rotating shaft, the diameter of the rotating shaft needs to be greater than a certain value to meet the strength of the rotating connection structure itself, and in order to reduce the thickness of the rotating connection structure and achieve thinness and lightness, it is necessary to reduce the diameter of the rotating shaft as much as possible. Therefore, there is a certain contradiction between the two. In the prior art, strength is usually given priority and thinness and lightness are abandoned. Therefore, how to design a thin rotating connection structure is a technical problem that needs to be solved at present. Utility Model Content

[0060] [First embodiment]

[0061] See also Figures 1a to 4 The first embodiment of the utility model provides a rotating connection structure. The rotating connection structure includes: a first connecting member 12, a second connecting member 14 and a limiting member 16. The first connecting member 12 includes a first connecting portion 126 and a fixed portion 122. The second connecting member 14 includes a second connecting portion 146 and a movable portion 142. The limiting member 16 is arranged between the fixed portion 122 and the movable portion 142, and the limiting member 16 is relatively fixed to the fixed portion 122, and the movable portion 142 is movably connected to the limiting member 16. The first connecting portion 126 and the second connecting portion 146 are used to connect with the first external member, and the first connecting portion 126 can be bent relative to the fixed portion 122, and the second connecting portion 146 can be bent relative to the movable portion 142 and at the same time drive the movable portion 142 to move relative to the limiting member 16.

[0062] The rotating connection structure provided in the first embodiment of the present invention realizes the rotating function by providing a first connecting member 12 and a second connecting member 14 with bending / rotating functions. The first connecting member 12, for example, includes a fixed portion 122, a first bending portion 124, and a first connecting portion 126. The second connecting member 14, for example, includes a movable portion 142, a second bending portion 144, and a second connecting portion 146.

[0063] The limiting member 16 is sandwiched between the fixed portion 122 and the movable portion 142. The first connecting portion 126 and the second connecting portion 146 are used to connect the first external component, and the first external component may be, for example, a supporting portion of a bracket, and the supporting portion may be, for example, a structure in a strip, ring, or pancake shape that can be used to support an electronic device and / or an accessory of an electronic device. The first connecting portion 126 and the second connecting portion 146 may be connected to each other, or may be fixed to the supporting portion separately. The first bending portion 124 and the second bending portion 144 may bend / rotate. Therefore, the rotating connection structure provided in the embodiment of the utility model can realize bending / rotation without a rotating shaft, so that the rotating connection structure can be used as a rotating element of the bracket; therefore, the rotating connection structure realizes the rotation function when the rotating shaft is removed, and the rotating connection structure thereby reduces its own thickness and achieves the technical effect of being lightweight.

[0064] See also Figure 1b and Figure 3 , and the first bending portion 124 and the second bending portion 144 are used as examples. Since the limiting member 16 is sandwiched between the first connecting member 12 and the second connecting member 14, and the first bending portion 124 and the second bending portion 144 are correspondingly arranged at the first end 169 of the limiting member 16; therefore, due to the existence of the limiting member 16, the first bending portion 124 and the second bending portion 144 are arranged at intervals. Furthermore, due to the interval arrangement of the first bending portion 124 and the second bending portion 144, the bending / rotation points (or bending / rotation axes) of the first bending portion 124 and the second bending portion 144 are not connected and are in different positions. By arranging the first connecting member 12 and the second connecting member 14, the rotating connection structure can be more stably suspended at the angle when bent to a certain angle. On the other hand, since the first connecting member 12 and the second connecting member 14 must have a certain thickness, if the first bending portion 124 and the second bending portion 144 rotate to a certain angle, the arc length of the movable member on the outer side of the bending arc must be greater than the arc length of the inner bending portion of the bending arc. Figure 3 The arc length of the second bent portion 144 is greater than the arc length of the first bent portion 124. Therefore, in the rotating connection structure provided in the first embodiment of the utility model, the movable connection between the limiter 16 and the movable portion 142 can enable the movable portion and the second bent portion 144 to move relative to the limiter 16, and satisfy the following conditions: Figure 3The arc length of the second bending portion 144 is shown to be greater than the arc length of the first bending portion 124. The interactive connection between the stopper 16 and the movable portion can be, for example, a sliding connection. Thus, the rotating connection structure provided in the embodiment of the utility model is easier to hover at the angle after rotating to a certain angle.

[0065] Specifically, Figure 3 As shown, the first bending portion 124 is located between the first connecting portion 126 and the fixed portion 122, and the first connecting portion 126 and the fixed portion 122 are relatively bent through the first bending portion 124. The second bending portion 144 is located between the second connecting portion 146 and the movable portion 142, and the second connecting portion 146 and the movable portion 142 are relatively bent through the second bending portion 144.

[0066] Further, see Figure 3 The stopper 16 includes a first end 169. When the first connection portion 126 is bent relative to the fixed portion 122 and the second connection portion 146 is bent relative to the movable portion 142, the first bending portion 124 and the second bending portion 144 are respectively located on both sides of the end surface S1 of the first end 169.

[0067] Specifically, the first bending portion 124 and the second bending portion 144 are correspondingly arranged at the first end 169 of the stopper 16 and are spaced apart due to the existence of the stopper 16. The first connecting member 12 and the second connecting member 14 are respectively provided with the first connecting portion 126 and the second connecting portion 146 on the side away from the stopper 16. The rotating connecting structure is characterized by being light and thin, and thus is in a plate shape as a whole, so there is a thickness direction, and the end surface S1 of the first end 169 is as shown in FIG. Figure 3 As shown, it is parallel to the thickness direction of the rotating connection structure. Figure 3 In the bent state shown in FIG. 1 , the first bending portion 124 and the second bending portion 144 are spaced apart by the stopper 16, so that the first bending portion 124 and the second bending portion 144 are spaced apart from each other. Figure 3 In the state shown, they are respectively located on both sides of the end surface S1.

[0068] In the embodiment of the present utility model, the first connecting portion 126 of the first connecting member 12 and the second connecting portion 146 of the second connecting member 14 can be as follows Figure 1bThe first connecting member 12 and the second connecting member 14 are connected to the stopper 16 by rotation; and the first connecting member 12 or the second connecting member 14 is connected to the stopper 16 by sliding. Therefore, the first connecting member 12 and the second connecting member 14 can rotate at the same time, and the first connecting member 12 and the second connecting member 14 can rotate at the same time. Figure 3 As shown, no matter the first connecting member 12 rotates upward or downward, by setting the corresponding connecting member, the limiting member 16 can be slid first, so that the first connecting member 12 and the second connecting member 14 can be easily bent. Figure 3 In the case shown, the second connecting member 14 is slidably connected to the limiting member 16. The first connecting member 12 and the second connecting member 14 are connected from Figure 1b The status shown is changed to Figure 2 During the process of the state shown, the movable portion 142 of the second connecting member 14 slides relative to the limiting member 16 .

[0069] Further, see Figure 1c , Figures 3 to 7 , or see Figures 8 to 12 , the movable part 142 is slidably connected with the limiting member 16, the second connecting member 14 also includes a sliding part arranged on the movable part 142, the limiting member 16 includes a slide groove, the sliding part is arranged in the slide groove and can slide in the slide groove; or the movable part 142 includes a slide groove, the limiting member 16 includes a sliding part, the sliding part is arranged in the slide groove and can slide in the slide groove. The slide groove cooperates with the sliding part to achieve the technical effect of sliding and limiting, so that the sliding of the second connecting member 14 relative to the limiting member 16 is more stable and reliable.

[0070] Specifically, see Figure 1c , Figure 3 and Figure 4 , shows a setting method of a sliding part and a sliding groove, wherein the limiting member 16 includes a sliding part, and the sliding groove is provided on the movable part 142 of the second connecting member 14. Taking the sliding connection relationship between the movable part 142 and the limiting member 16 as an example, the sliding groove is a first sliding limiting groove 141 provided on the movable part 142, and the sliding part is a first limiting protrusion 166 provided on the limiting member 16. The first limiting protrusion 166 is at least partially located in the first sliding limiting groove 141. When the rotating connection structure is in the state as shown in FIG. Figure 1c In the straight state shown in FIG. 1 , the first limiting protrusion 166 is located at one side of the first sliding limiting groove 141. When the rotating connection structure is bent and becomes Figures 2 to 4In the bent state shown in FIG. 1 , the second connecting member 14 will slide with the limiting member 16 at the movable portion 142 due to the rotation of the second bending portion 144; accordingly, the first limiting protrusion 166 moves relative to the first sliding limiting groove 141 and moves from Figure 1c The relative position shown becomes Figure 4 The relative positions shown.

[0071] Further, in Figure 1c , Figure 3 and Figure 4 In the rotating connection structure shown, the second connecting member 14 further includes a first damping portion provided on the movable portion 142 , and the limiting member 16 includes a second damping portion, and the first damping portion is in contact with the second damping portion.

[0072] Specifically, the first damping portion is the side wall of the first sliding limit groove 141, and the second damping portion is the first limit protrusion 166. Figure 4 In the bent state shown in FIG. 1 , the first limiting protrusion 166 is interference-fitted with the side wall of the first sliding limiting groove 141. The interference fit between the two can be achieved by placing the first sliding limiting groove 141 in the Figure 4 The vertical dimension shown is designed to be smaller than the first limiting protrusion 166 in the vertical direction. Figure 4 Thus, the first damping part and the second damping part are in contact and fit, so that the first connecting member 12 and the second connecting member 14 can have a better hovering effect when they are in a bent state, and prevent the first connecting member 12 and the second connecting member 14 from changing the bending angle by themselves.

[0073] When the first connecting member 12 and the second connecting member 14 are in a Figure 1c In the straight state shown in FIG. 1 , combined with the interference fit design of the first sliding limit groove 141 and the first limit protrusion 166 in the bent state, further see Figure 1c, the size of the first sliding limit groove 141 on the side close to the second bending portion 144 can be designed to be greater than or equal to the size of the first limit protrusion 166. Therefore, if the first connecting member 12 and the second connecting member 14 want to change from a straight state to a bent state, they must move from the looser part of the first sliding limit groove 141 to the narrower part, so that the first limit protrusion 166 is intercepted in the first sliding limit groove 141, and then the first connecting member 12 and the second connecting member 14 are intercepted in the straight state. And when the user wants to bend the first connecting member 12 and the second connecting member 14, the additional resistance generated by the above-mentioned interference fit will be clearly felt.

[0074] In addition, see Figures 8 to 10 , shows another arrangement of the sliding part and the slide groove, wherein the second connecting member 14 includes the sliding part, and the limiting member 16 includes the slide groove. The limiting member 16 includes, for example, Fig. 9 The limiting body 168 shown in the figure has a second sliding limiting groove 161 formed on one side connected to the second connecting member 14; correspondingly, a second limiting protrusion 143 is provided on the movable portion 142 of the second connecting member 14. That is, the sliding groove is the second sliding limiting groove 161, and the sliding portion is the second limiting protrusion 143. The cooperation between the second sliding limiting groove 161 and the second limiting protrusion 143 also achieves the technical effect of making the sliding of the second connecting member 14 relative to the limiting member 16 more stable and reliable.

[0075] Based on the above, the side wall of the second sliding limiting groove 161 and the second limiting protrusion 143 can be, for example, an interference fit, so as to achieve the technical effect that the first connecting member 12 and the second connecting member 14 are more stably suspended at a certain bending angle.

[0076] In addition, see Fig.16 and Fig.17 The first damping part and the second damping part may both be wave-shaped structures, thereby achieving the technical effect of the first connecting member 12 and the second connecting member 14 being stably suspended at any bending angle.

[0077] In addition, in the rotating connection structure provided in the embodiment of the present utility model, the side of the stopper 16 connected to the movable portion 142 may include a receiving portion, and the movable portion 142 is disposed in the receiving portion and is slidably connected in the receiving portion. Figure 4The stopper 16 includes a stopper body 168, and the stopper body 168 is connected to one side of the second connecting member 14 to form a groove, and the movable portion 142 is arranged in the groove of the stopper body 168, so that the movable portion 142 is arranged in the accommodating portion and is slidably connected to the accommodating portion. Through the above arrangement, the overall thickness of the rotating connection structure can be further reduced, thereby meeting the requirements of lightness and thinness.

[0078] Further, see Figures 5a to 7 , an embodiment of the utility model provides a rotating connection structure 100. The rotating connection structure 100, on the basis of the above-mentioned rotating connection structure of the embodiment of the utility model, further includes a third connecting member. The rotating connection structure is connected to the second external member through the third connecting member to achieve relative rotation between the first external member and the second external member. The second external member may be, for example, the back panel of a protective shell of an electronic device, or the outer shell of an electronic device such as a smart phone, a tablet computer, a mobile power source, and its accessories. Following the above-mentioned limitation on the first external member, the rotating connection structure 100 can achieve the flipping of the support portion of the bracket relative to the back panel or the outer shell, and enable the bracket to support the above-mentioned electronic device and its accessories.

[0079] Specifically, see Figure 5a , Figure 6 or Figure 8 The third connecting member includes a third connecting portion 11 and a fourth connecting portion 13. The third connecting portion 11 is arranged on the side of the first connecting member 12 away from the limiting member 16, and the fourth connecting portion 13 is arranged on the side of the second connecting member 14 away from the limiting member 16, and the third connecting portion 11 is fixedly connected to the fourth connecting portion 13. The third connecting member can be clamped up and down to limit the first connecting member 12, the second connecting member 14 and the limiting member 16 between the third connecting portion 11 and the fourth connecting portion 13.

[0080] Specifically, the fixing of the first connecting member 12, the second connecting member 14 and the stopper 16 by the third connecting member can be achieved by the structural cooperation of rivets and rivet holes; for example, see Figure 6 , the third connecting member also includes a rivet portion 114 provided on the third connecting portion 11, the first connecting member 12 includes a first rivet hole 123, and the stopper 16 includes a second rivet hole 1652. The rivet portion 114 passes through the first rivet hole 123 and the second rivet hole 1652 and is riveted and fixed to the fourth connecting portion 13. The rivet portion 114 extends into the first rivet hole 123 and the second rivet hole 1652 as a rivet, and accordingly, the fourth connecting portion 13 may also be provided with a rivet hole to cooperate with the rivet portion 114. Specifically, as Figure 6As shown, the first rivet hole 123 is, for example, disposed at an edge position of the first connecting member 12 , and the second rivet hole 1652 is, for example, disposed at an edge position of the limiting member 16 .

[0081] Further, see Figure 6 In the rotating connection structure 100, the edge of the first connection member 12 may be provided with a step portion and / or the edge of the stop member 16 may be provided with a step portion, and the third connection portion 11 is provided on the step portion, and for example Figure 7 As shown, the surface of the third connection part 11 is flush with the surface of the first connection member 12, or the surface of the third connection part 11 may be lower than the surface of the first connection member 12. Therefore, by setting the above-mentioned step portion, the thickness of the rotating connection structure 100 with the third connection member added can be further reduced, and the effect of lightness and thinness can be achieved.

[0082] In addition, when a third connecting member is added, Fig.11 and Fig.12 Another arrangement of the sliding part and the sliding groove is shown. The movable part 142 is slidably connected with the limiting member 16, the second connecting member further comprises a sliding part arranged on the movable part 142, the limiting member 16 comprises a sliding groove, the sliding part is arranged in the sliding groove and can slide in the sliding groove, and the fourth connecting part 13 is provided with an avoidance part, the avoidance part is used to avoid the sliding part. The limiting member 16 is provided with a fourth sliding limiting groove 164 as the sliding groove, and the second connecting member 14 is provided with a boss 145 as the sliding part. The avoidance part is, for example, a limiting protrusion 132.

[0083] Through the cooperation of the fourth sliding limit groove 164, the boss 145 and the limit protrusion 132, the following can be limited: Fig.12 and Fig.13 The sliding direction of the movable portion 142 shown in the figure makes the sliding of the second connecting member 14 more stable and reliable.

[0084] Further, see Fig.11 and Fig.12, the fourth connection part 13 includes an auxiliary limiting body 134, and the limiting protrusion 132 and the boss 145 are protruded toward the fourth sliding limiting groove 164. The limiting protrusion 132 is arranged on the auxiliary limiting body 134. When the first connection member 12 and the second connection member 14 are in a straight state, the boss 145 is overlapped and connected to the limiting protrusion 132 in a limiting manner. When the first connection member 12 and the second connection member 14 are in a bent state, the boss 145 is separated from the limiting protrusion 132, and the second connection member 14 abuts against the limiting protrusion 132. Specifically, the movable part 142 of the second connection member 14 abuts against the limiting protrusion 132. Through the above arrangement, similar to Figure 1c and Figure 4 The technical effect obtained by the scheme shown. When the first connecting member 12 and the second connecting member 14 are in a bent state, the movable portion 142 abuts against the limiting protrusion 132, thereby achieving an interference fit between the two, thereby enabling the first connecting member 12 and the second connecting member 14 to have a better hovering effect in the bent state. Fig.12 In the straight state shown, the boss 145 overlaps and is limitedly connected to the limiting protrusion 132, so that the first connecting member 12 and the second connecting member 14 are limited in the straight state. When the user pulls the first connecting part 126 and the second connecting part 146, the boss 145 overlaps the limiting protrusion 132 to change to a state where the movable part 142 abuts against the limiting protrusion 132, so that the user can clearly feel the additional resistance generated by the interference fit formed by the abutment between the two. Therefore, the first connecting member 12 and the second connecting member 14 are stably suspended at a specific folding angle.

[0085] In addition, in another embodiment, the boss 145 can also be, for example, protruding in the direction of the fourth sliding limit groove 164 and the fourth connecting part 13 at the same time, and the limiting protrusion 132 protrudes to the side away from the limiting member 16, thereby forming a groove on the side where the fourth connecting part 13 is connected to the second connecting member 14, and the boss 145 can be accommodated between the fourth sliding limit groove 164 and the groove, and when the first connecting member 12 and the second connecting member 14 are in a bent state, the boss 145 abuts against the fourth connecting part 13, thereby achieving an interference fit between the two.
