Description

Technical Field

[0001] This utility model relates to the field of bracket technology, and in particular to a folding bracket. Background Technology

[0002] With the development of network technology, more and more people need to use microphones, mobile terminals and monitors to participate in entertainment activities, and folding stands, as a commonly used support device, are also widely used.

[0003] In related technologies, folding stands typically adopt a quadrilateral structure with elastic elements added within it. These elastic elements overcome the gravity of the microphone, mobile terminal, and display, allowing the devices to hover. However, the elastic elements in these folding stands are generally exposed, which results in poor aesthetics and potential interference with external surfaces, affecting the usability of the folding stand. Furthermore, the external placement of the elastic elements also contributes to the relatively large size of the folding stand. Utility Model Content

[0049] like Figures 1 to 8As shown, this application provides a folding bracket, which includes a lower connector 1, an upper connector 2, an upper cantilever 3, a lower cantilever 4, an intermediate connector 5, and an elastic component 6. The lower connector 1 is used to fix it to a base, and the upper connector 2 is used to fix an object to be fixed, which may be, but is not limited to, a mobile device, a display, or a microphone and its clamps. The upper cantilever 3 includes a first arm 31 and a second arm 32, and the lower cantilever 4 includes a third arm 41 and a fourth arm 42. The first ends of the first arm 31 and the second arms 32 are hinged to different positions on the intermediate connector 5, the first ends of the third arm 41 and the fourth arms 42 are hinged to different positions on the intermediate connector 5, and the second ends of the first arm 31 and the second arms 32 are hinged to different positions on the upper connector 2. The second ends of the third arm 41 and the fourth arms 42 are hinged to different positions on the lower connector 1 to form two four-bar linkages. The elastic component 6 includes a first elastic element 6. 1. A second elastic element 62, a lower push rod 63, and an upper pull rod 64; a first elastic element 61 is disposed inside the first arm 31, with its first end connected to the first arm 31 and its second end connected to the second end of the upper pull rod 64; the first end of the upper pull rod 64 is hinged to the connection point between the second arm 32 and the intermediate connecting member 5; a second elastic element 62 is disposed inside the third arm 41, with its first end connected to the third arm 41 and its second end connected to the second end of the lower push rod 63; the first end of the lower push rod 63 is hinged to the connection point between the fourth arm 42 and the intermediate connecting member 5.

[0050] The folding bracket adopts two series-connected four-bar structures consisting of a lower connector 1, an upper connector 2, a middle connector 5, an upper cantilever 3, and a lower cantilever 4. The first elastic element 61 and the second elastic element 62 are hinged to the middle connector 5 through an upper pull rod 64 and a lower push rod 63, respectively. The first elastic element 61 and the second elastic element 62 support the suspension of the object to be fixed on the upper connector 2. The first elastic element 61 and the second elastic element 62 are respectively set inside the first arm 31 and the third arm 41, which can hide the first elastic element 61 and the second elastic element 62. On the one hand, it can make it more aesthetically pleasing, and on the other hand, by avoiding their exposure, it can reduce the possibility of interference with external components and reduce the possibility of the folding bracket being affected during normal use. At the same time, the first elastic element 61 and the second elastic element 62 being set inside the first arm 31 and the third arm 41 can also reduce the overall volume of the folding bracket.

[0051] It is understood that the lower connector 1, the upper connector 2, and the intermediate connector 5 are all provided with rotating holes, and the upper cantilever 3 and the lower cantilever 4 are all hinged to the lower connector 1, the upper connector 2, and the intermediate connector 5 via hinge shafts. For example, the hinge shafts may, but are not limited to, be locking screws.

[0052] In some embodiments, the first elastic member 61 may also be disposed within the second arm 32, and the second elastic member 62 may also be disposed within the fourth arm 42. When the first elastic member 61 is disposed within the second arm 32, the first end of the first elastic member 61 is connected to the second arm 32, and the second end of the first elastic member 61 is connected to the second end of the upper pull rod 64. The first end of the upper pull rod 64 is hinged to the connection point between the first arm 31 and the intermediate connecting member 5. Similarly, when the second elastic member 62 is disposed within the fourth arm 42, the first end of the second elastic member 62 is connected to the fourth arm 42, and the second end of the second elastic member 62 is connected to the second end of the lower push rod 63. The second end of the lower push rod 63 is hinged to the connection point between the third arm 41 and the intermediate connecting member 5.

[0053] like Figure 4 and Figure 5 As shown, in the current embodiment, the hinge positions of the first arm 31 and the second arm 32 on the intermediate connecting member 5, and the hinge positions of the third arm 41 and the fourth arm 42 on the intermediate connecting member 5, are located at both ends of the intermediate connecting member 5 along its length. In other embodiments, the hinge positions of the first arm 31 and the second arm 32 on the intermediate connecting member 5, and the hinge positions of the third arm 41 and the fourth arm 42 on the intermediate connecting member 5, can be located on both sides of the intermediate connecting member 5 along its width, so that the first arm 31 and the third arm 41 are coaxially arranged at their hinge positions on the intermediate connecting member 5; and the second arm 32 and the fourth arm 42 are coaxially arranged at their hinge positions on the intermediate connecting member 5.

[0054] For example, the first elastic element 61 and the second elastic element 62 may be, but are not limited to, compression springs.

[0055] To achieve the suspension of the object to be fixed, the first elastic element 61 is located in the first arm 31, the second elastic element is located in the third arm 41, and so on. Figure 2 Taking the state as an example, the first elastic element 61 is in a stretched state in the first arm 31, and is further stretched when the first elastic element 61 rotates clockwise with the first arm 31; the second elastic element 62 is in a compressed state in the third arm 41, and is further compressed when the second elastic element 62 rotates clockwise with the third arm 41.

[0056] In some embodiments, the upper cantilever 3 has a first adjustment range that can rotate around the intermediate connector 5, within which the first elastic element 61 is configured to always be in a stretched state; the lower cantilever 4 has a second adjustment range that can rotate around the lower connector 1, within which the second elastic element 62 is configured to always be in a compressed state. The first adjustment range and the second adjustment range can be the same angle range or two different angle ranges. The specific values ​​are not limited in this invention and can be set as needed.

[0057] In some embodiments, the direction in which the upper cantilever 3 rotates around the intermediate connector 5 and approaches the lower cantilever 4 is defined as the first rotation direction, which is either clockwise or counterclockwise. Within a first adjustment range, when the first elastic element 61 rotates with the upper cantilever 3 along the first rotation direction, the first elastic element 61 is further stretched; within a second adjustment range, when the second elastic element 62 rotates along the first rotation direction, the second elastic element 62 is further compressed.

[0058] like Figure 3 As shown, in order to facilitate the fixing of the first elastic element 61 and make it easy to stretch the first elastic element 61, the first arm 31 is cylindrical. The first elastic element 61 and the first arm 31 are arranged in the same direction. The cylindrical wall of the first arm 31 is provided with an inlet for the upper pull rod 64 to pass through. A fixing hook 311 is provided inside the first arm 31. The first end of the first elastic element 61 is hooked on the fixing hook 311, and the second end of the upper pull rod 64 is also provided with a structure bent into a hook shape, so that it can be hooked on the second end of the first elastic element 61 through the inlet, so that the first elastic element 61 is in a stretched state and maintains stability. To facilitate the fixing and compression of the second elastic element 62, the third arm 41 is also cylindrical. The second elastic element 62 and the third arm 41 extend in the same direction. The cylindrical wall of the third arm 41 is also provided with an inlet for the lower push rod 63 to extend into. A support seat 411 is provided inside the third arm 41. The second elastic element 62 is clamped between the support seat 411 and the inner wall of the third arm 41. The support seat 411 has a recessed groove on the side facing the lower push rod 63. The second end of the lower push rod 63 abuts against the recessed groove through the inlet, so that the second elastic element 62 is in a compressed state and maintains stability.

[0059] like Figure 7 As shown, in some embodiments, the folding bracket further includes friction components 8. Friction components 8 are provided on at least one hinge shaft 7 between the upper cantilever 3 and the upper connector 2, between the upper cantilever 3 and the intermediate connector 5, between the lower cantilever 4 and the lower connector 1, and between the lower cantilever 4 and the intermediate connector 5. Each friction component 8 is relatively stationary with its corresponding lower connector 1, upper connector 2, or intermediate connector 5, thereby providing stable friction force and further stabilizing the hovering capability.

[0060] In the current embodiment, the friction assembly 8 includes at least one friction plate 81. Friction plates 81 are provided between the third arm 41 and the lower connector 1, between the third arm 41 and the intermediate connector 5, between the first arm 31 and the upper connector 2, and on the hinge shaft 7 between the first arm 31 and the intermediate connector 5. Each friction plate 81 is provided with a through hole to allow the hinge shaft 7, which allows the first arm 31 or the third arm 41 to rotate, to pass through. The friction plate 81 is relatively stationary with respect to its corresponding lower connector 1, upper connector 2, or intermediate connector 5. Taking the fourth arm 42 connected to the intermediate connector 5 as an example, the first end of the fourth arm 42 is provided with two connecting ears 427. The corresponding intermediate connector 5 is provided with a connecting groove 52. The connecting ears 427 are inserted into the connecting groove 52. The hinge shaft 7 passes through the connecting ears 427 and the groove wall of the connecting groove 52, thereby enabling the fourth arm 42 to rotate relative to the intermediate connector 5. Based on the arrangement of the two connecting ears 427, two friction plates 81 are provided, which are clamped between the two connecting ears 427 and the groove wall of the connecting groove 52. It should be noted that the intermediate connector 5 has three connecting grooves 52, two of which are used to accommodate the connecting ears 427, and the other is used to accommodate the upper pull rod 64 or the lower push rod 63. The upper pull rod 64 or the lower push rod 63 is also sleeved on the corresponding hinge shaft 7.

[0061] In the current embodiment, the two friction plates 81 in the friction assembly 8 are connected by a fixing arm 82. To ensure connection strength, the friction plates 81 and the fixing arm 82 are integrally formed. To ensure the relative fixation of the friction plates 81, a fixing groove 51 is also provided on the intermediate connecting member 5. The fixing arm 82 is embedded and fixed in the fixing groove 51, and the two friction plates 81 are placed between the connecting ear 427 and the groove wall of the connecting groove 52. Similarly, the friction assemblies 8 on the lower connecting member 1 and the upper connecting member 2 can be set in the same way as described above, and the specific details will not be repeated.

[0062] like Figures 4 to 6 As shown, in some embodiments, the upper cantilever 3 and / or the lower cantilever 4 are provided with cable management channels 421, thereby enabling various cables to be buried within the upper cantilever 3 and / or the lower cantilever 4, reducing exposure and further improving aesthetics. In the current embodiment, both the upper cantilever 3 and the lower cantilever 4 are provided with the aforementioned cable management channels 421. To avoid interference, a first elastic member 61 is provided in the first arm 31, the cable management channel 421 of the upper cantilever 3 is provided in the second arm 32; the second elastic member 62 is provided in the third arm 41, and the cable management channel 421 of the lower cantilever 4 is provided in the fourth arm 42. The opening of the cable management channel 421 can also be provided with a cable shielding cover 9, which reduces the entry of debris and further improves aesthetics.

[0063] Specifically, such as Figure 6As shown, the second arm 32 and the fourth arm 42 include a base plate 422 and two side plates 423. The two side plates 423 are disposed on opposite sides of the base plate 422. The base plate 422 and the two side plates 423 form a cable management groove 421. The opening of the cable management groove 421 faces away from the first arm 31 or the third arm 41, thereby facilitating the insertion of cables into the cable management groove 421. To reduce cable end leakage, a cover plate 424 is connected to the base plate 422 or the side plate 423. The cover plate 424 at least partially covers the opening of the cable management groove 421, thereby reducing the size of the opening of the cable management groove 421 and further restraining the cables. Furthermore, a first magnetic element 426 is provided on the shielding plate 424, and the wire shielding cover 9 is attracted to the shielding plate 424 by the first magnetic element 426. In the current embodiment, the wire shielding cover 9 is also a groove-shaped structure, the first magnetic element 426 is attracted to the bottom of the groove of the wire shielding cover 9, and the wire shielding cover 9 covers the outside of the upper cantilever 3 or the lower cantilever 4. Exemplarily, the first magnetic element 426 is a magnet. Exemplarily, the wire shielding cover 9 covers the side of the upper wire channel 421 in the upper cantilever 3 and the lower cantilever 4, as well as the two sides adjacent to the side of the wire channel 421.

[0064] Furthermore, such as Figure 5 and Figure 6 As shown, in order to reduce the movement of the wire cover 9, the cover plate 424 is provided with a first limiting part 425, and the wire cover 9 is provided with a second limiting part 91 that cooperates with the first limiting part 425 to limit the movement. When the wire cover 9 is placed on the cover plate 424, the first limiting part 425 and the second limiting part 91 limit the movement. One of the first limiting part 425 and the second limiting part 91 is a limiting protrusion, and the other is a limiting hole.

[0065] like Figure 3 and Figure 4 As shown, when the folding bracket is not in use, the upper cantilever 3 can be folded to the lower cantilever 4, thereby reducing the space occupied. To prevent the upper cantilever 3 from unintentionally detaching from the lower cantilever 4 in this case, the upper cantilever 3 and / or the lower cantilever 4 are provided with a second magnetic chuck 10, thereby fixing the upper cantilever 3 and the lower cantilever 4 at the joint. In the current embodiment, the second magnetic chuck 10 is disposed inside the lower cantilever 4, and the second magnetic chuck 10 may be, but is not limited to, a magnet. The upper cantilever 3 can be folded from... Figure 2 The posture shown rotates around the intermediate connector 5 in the first rotation direction until... Figure 3 The upper cantilever 3 and the lower cantilever 4 are in contact, at which point, Figure 3 In the state shown, the upper cantilever 3 and the lower cantilever 4 are fixed together by magnetic attraction.

[0066] like Figure 1 and Figure 8As shown, in some embodiments, the folding bracket further includes a connector 20, which is fixed to the upper connector 2, thereby fixing the object to be fixed. Specifically, the connector 20 includes a clamp seat 201 and a ball joint connector 202. A fixing post 21 is provided on the upper connector 2. The clamp seat 201 includes a first clamp 2011, a second clamp 2012, and an adjusting member 2013. A retaining ring 2014 is provided on the first clamp 2011, which is sleeved on the fixing post 21 and axially limited by a limiting member 30 to allow the first clamp 2011 to rotate relative to the fixing post 21. The adjusting member 2013 connects the first clamp 2011 and the second clamp 2012. The adjusting member 2013 can adjust the distance between the first clamp 2011 and the second clamp 2012 to clamp or loosen the ball joint connector 202, thereby enabling the ball joint connector 202 to rotate through the rotation of the first clamp 2011. Specifically, the ball head connector 202 includes a ball head and a connecting post for connecting the ball head. The connecting post is provided with a connecting thread, and the object to be fixed or its clamp is connected and fixed through the thread. In order to cooperate in clamping the ball head of the ball head connector 202, the first clamping piece 2011 and the second clamping piece 2012 are provided with semi-circular grooves so as to better clamp the ball head.

[0067] More specifically, a screw hole is provided on the end face of the fixing post 21. The limiting member 30 includes a screw 301 and a baffle 302. The baffle 302 is annular. The screw 301 passes through the baffle 302 and fixes the baffle 302 to the end face of the fixing post 21. The screw 301 is locked with the screw hole, thereby allowing the baffle 302 to block the retaining ring 2014 and prevent the retaining ring 2014 from falling off the fixing post 21. The retaining ring 2014 is sleeved on the fixing post 21, so that after the screw 301 is loosened, the clamp seat 201 can be removed, which is convenient for installation and subsequent maintenance. One of the first clamping piece 2011 and the second clamping piece 2012 is provided with a through hole, and the other is also provided with a threaded hole. The adjusting component 2013 is a knob rod with a thread, which allows the knob rod to be screwed into the threaded hole through the through hole. The distance between the first clamping piece 2011 and the second clamping piece 2012 can be adjusted by turning the knob rod to tighten or loosen the ball head connector 202.

[0068] In some embodiments, a limiting portion is provided on the inner wall of the second clamping piece 2012. One side of the limiting portion abuts against the baffle 302, and the other side of the limiting portion abuts against the retaining ring 2014. Thus, the limiting portion is clamped between the baffle 302 and the retaining ring 2014, thereby initially limiting the position along the axial direction of the fixing post 21. Then, the first clamping piece 2011 and the second clamping piece 2012 are connected together by the adjusting member 2013 to achieve a stable connection.

[0069] In some embodiments, the folding bracket further includes a base 40, and a lower connector 1 is disposed on the base 40. The base 40 can be fixedly connected to the base, and the form of the base 40 is not specifically limited.

[0070] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
