Description

Technical Field

[0001] This application relates to the field of electronic device bracket technology, specifically to a portable electronic device bracket and its folding mechanism. Background Technology

[0002] A portable electronic device stand is a portable device used to support electronic devices such as mobile phones, cameras, and tablets. Portable electronic device stands can be tripod-style selfie sticks, handheld selfie sticks, or mobile phone stands (such as outdoor live-streaming mobile phone stands). Some stands are adjustable in length for easy storage and carrying, but their minimum length after storage is still relatively long. For example, adjustable stands typically have a telescopic rod composed of multiple sliding sub-rods that are stacked on top of each other. When stored, the minimum length of the telescopic rod is limited by the length of the sub-rods. To increase the support strength of the telescopic rod, the sub-rods cannot be too short, resulting in a relatively long minimum length after storage, which is not conducive to the stand's storage and carrying. Summary of the Invention

[0003] This application provides a portable electronic device holder and its folding mechanism, which can solve the problem of inconvenient storage and carrying of the holder.

[0004] According to one aspect of this application, one embodiment provides a portable electronic device holder, comprising:

[0005] The first support member has an adjustable length.

[0006] A second support member, the length of which is telescopically adjustable; and

[0007] A folding mechanism includes a first rotating head, a second rotating head, and a connecting seat. The first rotating head is fixedly connected to a first support member, and the second rotating head is fixedly connected to a second support member. The first rotating head and the second rotating head are rotatably connected to the connecting seat, so that the first support member and the second support member can be in an open state and a folded state.

[0008] The first rotating head is provided with a first positioning part, and the second rotating head is provided with a second positioning part. The first positioning part and the second positioning part abut against each other in the open state to restrict the rotation of the first rotating head and the second rotating head along the opening direction.

[0009] The first rotating head is provided with a first engaging part having multiple teeth, and the second rotating head is provided with a second engaging part having multiple teeth. The first engaging part and the second engaging part engage. In the open state, the teeth of one of the first engaging part and the corresponding tooth groove of the other engaging part abut against each other to form an interaction force, thereby restricting the rotation of the first rotating head and the second rotating head along the folding direction and locking the open state.

[0010] In one embodiment, the line connecting the rotation center of the first rotating head and the rotation center of the second rotating head is the first line; in the open state, the contact position where the tooth of one of the first meshing parts and the tooth groove corresponding to the other meshing part abuts is the first position, and the contact position where the first positioning part and the second positioning part abuts is the second position, the first position is located on one side of the first line, and the second position is located on the other side of the first line.

[0011] In one embodiment, the distance between the first position and the first connecting line is 10%-20% of the length of the first connecting line.

[0012] In one embodiment, the first positioning part is a first plane and the second positioning part is a second plane. In the open state, both the first plane and the second plane are perpendicular to the first connecting line.

[0013] In one embodiment, the teeth of one of the first and second meshing portions include locking teeth, and the tooth groove of the other meshing portion includes an abutment groove. The locking teeth have a protrusion with an arcuate surface, and the abutment groove has a third plane. The arcuate surface abuts against the third plane to form the interaction force.

[0014] In one embodiment, the protrusion is located at the top of the locking tooth and protrudes from the tooth top on the side close to the first positioning part or the second positioning part. The bottom of the abutment groove is provided with an inclined third plane, and the arc-shaped surface abuts against the inclined third plane to form the interaction force.

[0015] In one embodiment, in the folded state, the teeth of one of the first and second meshing portions abut against the corresponding tooth grooves of the other meshing portion to form an interaction force, thereby restricting the rotation of the first and second rotating heads along the opening direction and locking the folded state.

[0016] In one embodiment, the first rotating head and / or the second rotating head are provided with a locking hole, and a pin and a toggle are movably mounted on the connecting seat. The toggle is exposed outside the connecting seat and is connected to the pin to drive the pin to be inserted into the locking hole to lock the open state or the folded state.

[0017] In one embodiment, a locking head is movably mounted on one of the rotating head and the connecting seat, and a locking groove is provided on the other. The locking head is used to be removably locked into the locking groove in the open state or the folded state to lock the open state or the folded state.

[0018] According to another aspect of this application, one embodiment provides a folding mechanism for a portable electronic device holder, comprising:

[0020] A second rotating head is used for fixed connection with the second support member; and

[0021] A connecting seat is provided, and the first rotating head and the second rotating head are rotatably connected to the connecting seat so that the first support member and the second support member can be in an open state and a folded state. The first rotating head is provided with a first positioning part, and the second rotating head is provided with a second positioning part. The first positioning part and the second positioning part abut against each other in the open state to restrict the rotation of the first rotating head and the second rotating head along the opening direction.

[0022] The first rotating head is provided with a first meshing part having multiple teeth, and the second rotating head is provided with a second meshing part having multiple teeth. The first meshing part and the second meshing part mesh together. The teeth of one of the first meshing parts and the corresponding tooth grooves of the other meshing part abut against each other to form an interaction force, thereby restricting the rotation of the first rotating head and the second rotating head along the folding direction and locking the open state.

[0023] According to the portable electronic device holder and its folding mechanism of the above embodiment, the first rotating head and the second rotating head are rotatably connected to the connecting base. The first rotating head is provided with a first engaging portion having multiple teeth, and the second rotating head is provided with a second engaging portion having multiple teeth. The first engaging portion and the second engaging portion engage. In the open state, the teeth of one of the first engaging portions and the corresponding tooth grooves of the other engaging portion abut against each other to form an interaction force, thereby restricting the rotation of the first rotating head and the second rotating head along the folding direction and locking the open state. When storing, force can be applied to pry the first and second supporting members, thereby realizing the opening and folding of the holder, which helps to reduce the length of the holder after storage and facilitates the storage and carrying of the holder.

Detailed Implementation

[0041] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0042] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0043] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the objects being described and have no sequential or technical meaning. Unless otherwise specified, the terms "connection" and "linkage" used in this application include both direct and indirect connections (linkages).

[0044] In related technologies, some support frames are length-adjustable for easy storage and carrying, but their minimum length after storage is still relatively long. For example, adjustable support frames generally have a telescopic rod, which is composed of multiple sub-rods that slide together. The sub-rods are stacked sequentially, and the minimum length of the telescopic rod after storage is limited by the length of the sub-rods. Moreover, the longer the maximum length that the telescopic rod can extend, the longer the length of each sub-rod will be to increase the support strength of the telescopic rod, resulting in a still relatively long minimum length after storage, which is not conducive to the storage and carrying of the support frame.

[0045] Based on this, this application utilizes the engagement of a first meshing part and a second meshing part. In the open state, the teeth of one meshing part abut against the corresponding tooth groove of the other meshing part, forming an interaction force to restrict the rotation of the first and second rotating heads along the folding direction, thus locking the open state. During storage, force can be applied to pry open the first and second support members, thereby realizing the opening and folding of the bracket, which helps to reduce the length of the bracket after storage and facilitates its storage and carrying.

[0046] The following describes some embodiments of the portable electronic device holder and its folding mechanism provided in this application, with reference to the accompanying drawings.

[0047] Please see Figures 1 to 15 This application provides a folding mechanism 10 for a portable electronic device holder, including a first rotating head 1, a second rotating head 2, a connecting seat 3, and other functional components as needed, which are described in detail below.

[0048] In this embodiment, the first rotating head 1 is fixedly connected to the first support member 20, and the second rotating head 2 is fixedly connected to the second support member 30. The first rotating head 1 and the second rotating head 2 are rotatably connected to the connecting seat 3, allowing the first support member 20 and the second support member 30 to have an open state and a folded state. The first support member 20 and the second support member 30 are open when they rotate away from each other, and folded when they rotate closer to each other.

[0049] In some embodiments, the first rotating head 1 and the second rotating head 2 can both be rotatably connected to the connecting seat 3 via pins. Specifically, holes can be provided on the first rotating head 1, the second rotating head 2, and the connecting seat 3. The pin passes through the holes on the first rotating head 1 and the connecting seat 3 to hinge the first rotating head 1 to the connecting seat 3, and the pin passes through the holes on the second rotating head 2 and the connecting seat 3 to hinge the second rotating head 2 to the connecting seat 3. However, this is not limited to this. Alternatively, a shaft-shaped boss can be fixedly provided on the connecting seat 3, and the first rotating head and the second rotating head can be fitted onto the shaft-shaped boss to form a rotatable connection. This embodiment does not limit the specific structure of the connecting seat 3. The first rotating head 1 and the second rotating head 2 can be connected in any way. For example, the connecting seat 3 can be a block or plate structure, with one end of the connecting seat 3 rotatably connected to the first rotating head 1 and the other end rotatably connected to the second rotating head 2.

[0050] In this embodiment, as Figures 2-14 As shown, the first rotating head 1 is provided with a first positioning part 102, and the second rotating head 2 is provided with a second positioning part 202. The first positioning part 102 and the second positioning part 202 abut against each other in the open state to restrict the rotation of the first rotating head 1 and the second rotating head 2 along the opening direction. When opening, the first support member 20 and the second support member 30 rotate away from each other until the first positioning part 102 and the second positioning part 202 come into contact, thus restricting the continued rotation of the rotating head, i.e., the head is fully opened. The abutment of the first positioning part 102 and the second positioning part 202 restricts the continued rotation of the first rotating head 1 and the second rotating head 2 along the opening direction, thereby limiting the maximum opening angle between the first support member 20 and the second support member 30 to avoid over-opening, ensuring quick and convenient opening.

[0051] In this embodiment, the first rotating head 1 is provided with a first engaging portion 101 having multiple teeth, and the second rotating head 2 is provided with a second engaging portion 201 having multiple teeth. The first engaging portion 101 and the second engaging portion 201 engage. In the open state, the teeth of one of the engaging portions of the first engaging portion 101 and the corresponding tooth grooves of the other engaging portion abut against each other to form an interaction force, thereby restricting the rotation of the first rotating head 1 and the second rotating head 2 and locking the open state.

[0052] Understandably, the engagement of the first meshing part 101 and the second meshing part 201 facilitates the synchronous rotation of the first rotating head 1 and the second rotating head 2, while also providing mutual restraint, making the structure of the folding mechanism 10 more stable and the opening and folding movements smoother. In the open state, the teeth of one meshing part of the first meshing part 101 and the corresponding tooth groove of the other meshing part abut against each other, forming an interaction force. That is, the abutting teeth and tooth grooves are in an interference fit, and the abutting teeth apply a pushing force to the surface of the tooth groove. At the same time, the surface of the tooth groove also applies a corresponding force to the teeth. This interaction force is used to restrict the rotation of the first rotating head 1 and the second rotating head 2, thereby locking the open state and preventing the first rotating head 1 and the second rotating head 2 from rotating along the folding direction. Because the contact between the first positioning part 102 and the second positioning part 202 can restrict the rotation of the first rotating head 1 and the second rotating head 2 in the opening direction, and the contacting teeth and grooves can also restrict the rotation of the first rotating head 1 and the second rotating head 2 in the folding direction, it is beneficial to maintain the stability of the opening state. In this application, apart from the contacting teeth and grooves, the other teeth and grooves on the first meshing part 101 and the second meshing part 201 are all normal meshing dimensions. Moreover, the distance between the contacting teeth and their adjacent normal teeth on the meshing part is equal to the distance between the normal teeth and their adjacent normal teeth. The contacting teeth can be provided on the first meshing part 101, and the corresponding contacting grooves are provided on the second meshing part 201; the contacting teeth can also be provided on the second meshing part, and the corresponding contacting grooves are provided on the first meshing part 101.

[0053] When the opening mechanism is activated, the first rotating head 1 and the second rotating head 2 rotate in the opening direction until the first positioning part 102 and the second positioning part 202 come into contact. Figure 4 , Figure 5 As shown, the teeth and grooves between the first meshing part 101 and the second meshing part 201 abut, thus completing the opening and maintaining the open state. During storage, an external force is applied to the first support member 20 and the second support member 30. This external force overcomes the interaction force between the abutting teeth and grooves, causing the first rotating head 1 and the second rotating head 2 to rotate in the folding direction until the first support member 20 and the second support member 30 overlap, thus completing the folding and storage. The bracket is convenient to open and fold, and the locking structure is simple. When the support member includes multiple nested sub-rods, the foldability reduces the length that a single support member needs to support, and the length of each sub-rod in the support member can be relatively reduced, which helps to reduce the minimum length of the support member after retraction, making it easier to carry.

[0054] In this embodiment, the folding mechanism 10 of the portable electronic device holder has a first rotating head 1 and a second rotating head 2 rotatably connected to a connecting base 3. The first rotating head 1 has a first engaging portion 101 with multiple teeth, and the second rotating head 2 has a second engaging portion 201 with multiple teeth. The first engaging portion 101 and the second engaging portion 201 engage. In the open state, the teeth of one engaging portion 101 and the corresponding tooth groove of the other engaging portion abut against each other to form an interaction force, thereby restricting the rotation of the first rotating head 1 and the second rotating head 2 along the folding direction and locking the open state. When storing, force can be applied to pry open the first and second supporting members, thus realizing the opening and folding of the holder. This helps to reduce the length of the holder after storage, making it easier to store and carry, and the locking structure is also simple.

[0055] In one embodiment, such as Figure 4 , Figure 5 As shown, the line connecting the rotation center of the first rotating head 1 and the rotation center of the second rotating head 2 is the first connecting line L. In the open state, the contact position where the teeth of one of the first engaging parts 101 and the corresponding tooth groove of the other engaging part abuts is the first position 5, and the contact position where the first positioning part 102 and the second positioning part 202 abuts is the second position 4. The first position 5 is located on one side of the first connecting line L, and the second position 4 is located on the other side of the first connecting line L. The first position 5 and the second position 4 are located on opposite sides of the first connecting line L, thereby ensuring that the anti-rotation interaction force formed by the contact between the first positioning part 102 and the second positioning part 202 is opposite to the anti-rotation interaction force formed by the contact between the teeth and tooth grooves, which is beneficial for achieving anti-rotation in both the opening and folding directions. For example, when analyzing the force-bearing object using the first rotating head 1 as an example, the second positioning part 202 abuts against the first positioning part 102, restricting the clockwise rotation (i.e., opening direction) of the first rotating head 1, and the toothed groove on the second engaging part 201 restricts the counterclockwise rotation (i.e., folding direction) of the first rotating head 1, thereby restricting the rotation of the first rotating head 1. In some embodiments, when the contact area between the first positioning part 102 and the second positioning part 202 is large, the first position 5 may also be partially located on one side of the first connecting line L and partially located on the other side of the first connecting line L, in which case locking can still be formed.

[0056] In one embodiment, the distance between the first position 5 and the first connecting line L is 10%-20% of the length of the first connecting line L. In this embodiment, the first position 5 can be the distance between the point where the tooth and tooth groove contact each other and the first connecting line L, or it can be the distance between the midpoint of the surface or line where the tooth and tooth groove contact each other and the first connecting line L. Within the range of 10%-20%, the anti-rotation effect formed by the contacting teeth and tooth grooves is better. In some embodiments, the distance between the first position 5 and the first connecting line L can also be set to other dimensions outside this range as needed.

[0057] In one embodiment, such as Figure 4 As shown, the first positioning part 102 is a first plane, and the second positioning part 202 is a second plane. In the open state, both the first plane and the second plane are perpendicular to the first connecting line L. The limiting effect formed by the contact between the first plane and the second plane is better. Since both the first plane and the second plane are perpendicular to the first connecting line L, the interaction force of the contact is parallel to the first connecting line L, thereby creating a better anti-rotation effect.

[0058] In some implementations, such as Figure 4 , Figure 6 As shown, the first positioning part 102 is connected to the end of the first engaging part 101 away from the first support member 20, and the second positioning part 202 is connected to the end of the second engaging part 201 away from the second support member 30. The positioning part is connected to the corresponding engaging part, which helps to simplify the structure of the rotating head and facilitates the integral manufacturing of the rotating head. Both the positioning part and the engaging part can be integrally set on the rotating head.

[0059] Specifically, both the first engaging part 101 and the second engaging part 201 can be arc-shaped structures with a central angle of 90 degrees. Each arc-shaped structure has multiple teeth evenly distributed along the circumferential direction, which is the circumferential direction of the arc-shaped structure. The first positioning part 102 is a first plane, which is connected to the end of the first engaging part 101 away from the first support member 20 and is perpendicular to the axial direction of the first support member 20. The second positioning part 202 is a second plane, which is connected to the end of the second engaging part 201 away from the second support member 30 and is perpendicular to the axial direction of the second support member 30. At this time, switching between the open state and the folded state only requires rotating the first rotating head 1 and the second rotating head 2 by 90 degrees. When both the first support member 20 and the second support member 30 are straight rods, the first support member 20 and the second support member 30 in the folded state can be arranged in parallel. When opened, the first rotating head 1 and the second rotating head 2 rotate by 90 degrees because each positioning part is connected to the corresponding engaging part, such as Figure 4 As shown, after rotating 90 degrees, the first positioning part 102 and the second positioning part 202 can abut together. Without considering external factors, the first support member 20 and the second support member 30 can extend along the same straight line, which is beneficial for supporting the electronic device. The arc-shaped structure allows the first rotating head 1 and the second rotating head 2 to mesh and rotate during rotation, and eliminates the need for additional tooth structures, thus reducing manufacturing costs. In some embodiments, a central angle slightly greater than 90 degrees or slightly less than 90 degrees is equivalent to the 90-degree arc-shaped structure in this embodiment. In some embodiments, the first positioning part 102 and the second positioning part 202 can also be other structures, such as non-planar surfaces with a concave-convex fit, which can further enhance the positioning effect when opening, or both can be arc surfaces.

[0060] In one embodiment, such as Figure 4 , Figure 5 As shown, the teeth of one of the first meshing portions 101 and the second meshing portion 201 include locking teeth 6, and the tooth groove of the other meshing portion includes an abutment groove 7. The locking tooth 6 has a protrusion 601 with an arcuate surface, and the abutment groove 7 has a third plane 701. The arcuate surface of the protrusion 601 abuts against the third plane 701 to form an interaction force. The protrusion 601 has a certain protrusion height, which is conducive to the interference fit between the locking tooth 6 and the abutment groove 7 and to the formation of the interaction force. The contact between the locking tooth 6 and the abutment groove 7 is better when the protrusion 601 abuts against the third plane 701. In some embodiments, the arcuate surface of the protrusion 601 may be a circular arc surface, and the third plane 701 may be tangent to the circular arc surface.

[0061] In one embodiment, such as Figure 5 As shown, the protrusion 601 is located at the tip of the locking tooth 6 and protrudes from the side of the tooth tip near the first positioning part 102 or the second positioning part 202. An inclined third plane 701 is provided at the bottom of the abutment groove 7. The arc-shaped surface of the protrusion 601 abuts against the third plane 701 to form an interaction force. Because the protrusion 601 protrudes from the side of the tooth tip near the first positioning part 102 or the second positioning part 202, the force formed after abutment is closer to the direction of rotation, which is more conducive to restricting rotation. The inclined third plane 701 is not perpendicular to the radial direction of the rotating head. The inclined third plane 701 facilitates the abutment of the protrusion 601. To facilitate abutment, the maximum depth of the abutment groove 7 can be less than the groove depth of other tooth grooves in the meshing part to facilitate an interference fit. In some embodiments, the protrusion 601 can also protrude from other parts of the locking tooth 6, for example, from the tooth tip. In this case, the third plane 701 can be a plane perpendicular to the radial direction of the rotating head. In some applications, there is no need to set an additional protrusion 601 on the locking tooth 6. The height of the locking tooth 6 can be increased directly so that the top of the locking tooth 6 can be interference-fitted in the abutment groove 7 to form an interaction force.

[0062] In one embodiment, such as Figure 6As shown, in the folded state, the teeth of one of the first engaging parts 101 and the corresponding tooth groove of the other engaging part abut against each other, forming an interaction force to restrict the rotation of the first rotating head 1 and the second rotating head 2 in the opening direction, thus locking the folded state. Locking in the folded state improves structural stability and facilitates carrying. The specific locking mechanism in the folded state can be the same as the locking mechanism in the open state. In the folded state, the contact position where the teeth of one of the first engaging parts 101 and the corresponding tooth groove of the other engaging part abut against each other is the third position 51. The third position 51 is located on one side of the first connecting line L, and the support member is located on the other side of the first connecting line L. The third position 51 forms an anti-rotation barrier in the opening direction, and the overlap of the first support member 20 and the second support member 30 forms an anti-rotation barrier in the folding direction, thereby locking the folded state.

[0063] In one embodiment, such as Figure 7 , Figure 8 As shown, the first rotating head 1 is further provided with a third positioning part 103, and the second rotating head 2 is further provided with a fourth positioning part 203. The third positioning part 103 and the fourth positioning part 203 abut against each other in the folded state to restrict the rotation of the first rotating head 1 and the second rotating head 2 along the folding direction. At this time, the third position 51 is located on one side of the first connecting line L, and the contact position between the third positioning part 103 and the fourth positioning part 203 is located on the other side of the first connecting line L.

[0064] Specifically, the third positioning part 103 can be a fourth plane, which is connected to the end of the first engaging part 101 near the first support member 20 and is parallel to the axial direction of the first support member 20. The fourth positioning part 203 can be a fifth plane, which is connected to the end of the second engaging part 201 near the second support member 30 and is parallel to the axial direction of the second support member 30. That is, the first plane and the third plane 701 are connected to both ends of the first engaging part 101, and the first plane and the fourth plane are perpendicular; the second plane and the fifth plane are connected to both ends of the second engaging part 201, and the second plane and the fifth plane are perpendicular. When both the first support member 20 and the second support member 30 are straight rods, the first support member 20 and the second support member 30 in the open state can be connected in a straight line (without considering external influencing factors). Applying force to the first support member 20 and the second support member 30 causes the first rotating head 1 and the second rotating head 2 to rotate in the folding direction until the third positioning part 103 and the fourth positioning part 203 abut. The first support member 20 and the second support member 30 can be arranged in parallel. The teeth of one of the first meshing parts 101 and the corresponding tooth grooves of the other meshing part abut against each other to form an interaction force, thereby restricting the rotation of the first rotating head 1 and the second rotating head 2 in the opening direction and locking the folded state.

[0065] Furthermore, such as Figures 4-6 As shown, the first engaging part 101 may have two locking teeth 6, and the corresponding second engaging part 201 may have two abutment grooves 7. One locking tooth 6 near the first positioning part 102 has an arc-shaped protrusion 601, which protrudes from the side of the locking tooth 6 near the first positioning part 102 and abuts against the inclined plane of the corresponding abutment groove 7 to restrict the rotation of the rotating head in the folding direction. The other locking tooth 6 away from the first positioning part 102 also has an arc-shaped protrusion 601, which protrudes from the side of the locking tooth 6 away from the first positioning part 102 and abuts against the inclined plane of the corresponding abutment groove 7 to restrict the rotation of the rotating head in the opening direction.

[0066] To increase the reliability of locking, such as Figures 7-14 As shown, a locking component 8 can also be additionally provided. The locking component 8 is used to restrict the rotation of the first rotating head 1 and the second rotating head 2 when in the open or folded state, so as to lock the open or folded state.

[0067] In some embodiments, the lengths of the first support member 20 and the second support member 30 are adjustable. In use, the first support member 20 and the second support member 30 are first opened, causing the first rotating head 1 and the second rotating head 2 to rotate in the opening direction until the first positioning part 102 and the second positioning part 202 abut against each other. At this point, the locking teeth 6 abut against the abutment groove 7 to form a lock, and the opening state is further locked by the locking component 8, thus maintaining the opening state. Then, the lengths of the first support member 20 and the second support member 30 can be adjusted as needed. The opened bracket is as follows: Figure 1 As shown. When storing, first retract the first support member 20 and the second support member 30, then release the locking assembly 8, fold the first support member 20 and the second support member 30, and rotate the first rotating head 1 and the second rotating head 2 along the folding direction until the first support member 20 and the second support member 30 overlap, and the other locking tooth 6 abuts against the corresponding abutment groove 7. The locking assembly 8 further locks the folded state, maintaining it. The folded bracket is as follows: Figure 15 As shown. The bracket is not only telescopic and adjustable, but also can be opened and folded, making it more flexible to use and convenient to open and fold. The locking effect in both the open and folded states is also good. In addition, when the support consists of multiple nested sub-rods, the folding capability reduces the length that a single support needs to support, and the length of each sub-rod in the support can be relatively reduced, which helps to reduce the minimum length of the support after it is retracted, making it easier to carry.

[0068] The following examples illustrate specific implementations of the locking component 8.

[0069] In one embodiment, such as Figures 7-9As shown, the locking assembly 8 includes a pin 805 and an actuating element 801 connected to the pin 805. Both the pin 805 and the actuating element 801 are movably mounted on the connecting seat 3. The first rotating head 1 and / or the second rotating head 2 are provided with locking holes 12. The actuating element 801 is used to drive the pin 805 into the locking hole 12 to lock in either the open or folded state. The locking formed by the pin 805 inserted into the locking hole 12 is stable and reliable. When locked in the open state, the locking hole 12 on the rotating head is in the open position. After the first rotating head 1 and the second rotating head 2 rotate relative to the connecting seat 3, the open locking hole 12 corresponds to the pin 805. Applying force to the actuating element 801 causes the pin 805 to insert into the locking hole 12, thus forming the lock in the open state. When locked in the folded state, the locking hole 12 on the rotating head is the locking hole 12 for the folded position. After the first rotating head 1 and the second rotating head 2 rotate relative to the connecting seat 3 to their respective positions, the locking hole 12 for the folded position corresponds to the pin 805. Applying force to move the actuating member 801 causes the pin 805 to insert into the locking hole 12, thus forming a lock in the folded state. In some embodiments, the rotating head may only have a locking hole 12 for the open position, or it may have both a locking hole 12 for the open position and a locking hole 12 for the folded position. In some embodiments, the first rotating head 1 and the second rotating head 2 may both have locking holes 12, in which case there are two corresponding pins 805; or the locking hole 12 may only be provided on one rotating head, in which case there is one corresponding pin 805.

[0070] Furthermore, such as Figure 8 , Figure 9 As shown, the axis of the lock hole 12 is parallel to the axis of the rotation center of the first rotating head 1 or the second rotating head 2, and the lock hole 12 is offset from the rotation center. The connecting seat 3 has a mounting hole 303 corresponding to the lock hole 12. The pin 805 is movably mounted in the mounting hole 303. The actuating member 801 is used to drive the pin 805 to extend from the mounting hole 303 and insert into the lock hole 12, and to drive the pin 805 to reset to release the lock. In this embodiment, the rotation of the rotating head means that the lock hole 12 rotates around the rotation center. After the rotating head reaches its position, the lock hole 12 communicates with the mounting hole, at which point the pin 805 can be smoothly inserted into the lock hole 12 to form a lock.

[0071] Specifically, such as Figure 9As shown, the locking assembly 8 also includes a wedge-shaped drive block 804. A drive ramp 803 is provided on one side of the drive block 804, and a pin 805 is fixedly provided on the opposite side. The actuating member 801 has a drive portion 802, which slides on the drive ramp 803 to force the drive block 804 to move and drive the pin 805 to extend out of the mounting hole 303. When the drive portion 802 slides on the drive ramp 803, it forces the drive block 804 to move along the axis of the rotation center, thereby causing the pin 805 to move along the axis of the rotation center and extend out of the mounting hole 303. The drive structure of the pin 805 is simple. In some embodiments, the connecting seat 3 may be provided with a mounting cover 301 and a base plate 302. The mounting cover 301 and the base plate 302 are connected to form a hollow structure, and the drive block 804 is disposed within this hollow structure. The actuating element 801 is slidably fitted into a slotted hole in the mounting cover 301 or the base plate 302. The driving part 802 of the actuating element 801 is located within a hollow structure and contacts the driving inclined surface 803 of the driving block 804. The mounting cover 301 has a mounting hole 303, into which the pin 805 on the driving block 804 is inserted. In some applications, to reset the pin 805, a reset spring 807 can be provided between the mounting cover 301 and the driving block 804. When the actuating element 801 is pushed in the reset direction, the reset spring 807 gradually recovers its deformation to push the driving block 804 to reset, causing the pin 805 to retract into the mounting hole 303. Alternatively, a groove can be provided on the driving inclined surface 803, and the driving part 802 slidably fits in the groove. When the actuating element 801 is pushed, the driving part 802 slides in the groove and simultaneously pulls or pushes the driving block 804 to move along the axis of the rotation center to reset.

[0072] In another embodiment, such as Figures 11-14 As shown, the locking component 8 may include a locking head 806. The locking head 806 is movably mounted on one of the rotating head and the connecting seat 3, and a locking slot 13 is provided on the other. The locking head 806 is used to be removably locked into the locking slot 13 in the open or folded state to lock the open or folded state. After rotating to the correct position, the locking head 806 can automatically lock into the locking slot 13 to form a lock. The locking is simple and quick, without manual operation. One locking head 806 can be provided, and one or two locking slots 13 can be provided. For example, when locking only in the open state, only one locking slot 13 can be provided. When locking in both the open and folded states is required, one locking slot 13 can be provided for the open position and one for the folded position respectively.

[0073] Furthermore, such as Figure 11 , Figure 12As shown, the locking head 806 can be mounted on the rotating head. A first guide hole 14 can be provided on the first rotating head 1 and / or the second rotating head 2. A spring 807 is provided inside the first guide hole 14, and the end of the spring 807 is fixedly connected to the locking head 806. A slot 13 corresponding to the locking head 806 is provided on the connecting seat 3. The locking head 806 is mounted on the rotating head; when the rotating head rotates, the locking head 806 rotates synchronously. After the rotating head reaches its position, the locking head 806 engages in the slot 13, forming a lock. In this embodiment, the first guide hole 14 is offset from the rotation center of the rotating head. When locking is required in both the open and folded states, two slots 13 can be provided on the connecting seat 3. An arc-shaped groove 304 is provided between the two slots 13. This arc-shaped groove 304 allows the spring 807 to return to its original position, reducing the friction of the locking head 806 during the rotation of the rotating head and facilitating smooth rotation. In some embodiments, the locking head 806 may be spherical to facilitate the locking head 806 engaging or disengaging from the slot 13. In this embodiment, first guide holes 14 may be provided on both the first rotating head 1 and the second rotating head 2, and slots 13 corresponding to the first rotating head 1 and the second rotating head 2 may be provided on the connecting seat 3; alternatively, the first guide hole 14 may be provided on only one rotating head, and the connecting seat 3 may only have slots 13 corresponding to one rotating head. This embodiment does not limit the specific fixing method of the spring 807. It may be directly fixed in the guide hole, or it may be restricted in the guide hole by the connecting seat 3. For example, the connecting seat 3 includes two connecting plates, one of which is located on one side of the rotating head and has a slot 13 thereon, and the other connecting plate is located on the other side of the rotating head, covering the first guide hole 14 to restrict the spring 807 in the first guide hole 14.

[0074] In some implementations, such as Figure 13 , Figure 14As shown, the locking head 806 can be mounted on the connecting seat 3. The first rotating head 1 and / or the second rotating head 2 can be provided with a boss 9, which is located at the rotation center of the rotating head. A slot 13 is provided on the side wall of the boss 9. The connecting seat 3 is provided with a groove 306 and a second guide hole 305 communicating with the groove 306. A spring 807 is provided in the second guide hole 305. The end of the spring 807 is fixedly connected to the locking head 806. The boss 9 is inserted into the groove 306 so that the locking head 806 corresponds to the slot 13. The slot 13 is provided on the rotating head. When the rotating head rotates, the boss 9 will rotate. After the rotating head rotates to the correct position, the slot 13 on the boss 9 is easy for the locking head 806 to align, and the locking head 806 is locked into the slot 13 to form a lock. When it is necessary to lock both the open and folded states, two slots 13 can be provided on the boss 9, and the two slots 13 can be 90 degrees apart. When both the first rotating head 1 and the second rotating head 2 are provided with slots 13, a spring 807 can be provided in the second guide hole 305. A locking head 806 is fixed at both ends of the spring 807. One locking head 806 corresponds to the slot 13 on the first rotating head 1, and the other locking head 806 corresponds to the slot 13 on the second rotating head 2.

[0075] To increase the structural stability of the folding mechanism 10, such as Figure 7 , Figure 8 , Figure 10 As shown, the first rotating head 1 and the second rotating head 2 may be provided with corresponding through grooves 11 to form a "Y"-shaped rotating head. The connecting seat 3 is assembled in the through groove 11, and the first rotating head 1 and the second rotating head 2 are respectively hinged to the connecting seat 3 by pins. The connecting seat 3 is located in the through groove 11 of the first rotating head 1 and the second rotating head 2, thereby providing a better restriction effect on the rotation of the rotating head in the rotation direction. In some embodiments, the first rotating head 1 and the second rotating head 2 may also be provided on one side of the connecting seat 3; the connecting seat 3 may also include two combined components, such as the connecting plate described above, with the first rotating head 1 and the second rotating head 2 sandwiched between the two combined components.

[0076] The folding mechanism 10 of the portable electronic device holder provided in the above embodiment has a first rotating head 1 and a second rotating head 2 rotatably connected to a connecting base 3. The first rotating head 1 is provided with a first engaging portion 101 having multiple teeth, and the second rotating head 2 is provided with a second engaging portion 201 having multiple teeth. The first engaging portion 101 and the second engaging portion 201 engage. In the open state, the teeth of one of the engaging portions 101 and the corresponding tooth grooves of the other engaging portion abut against each other to form an interaction force, thereby restricting the rotation of the first rotating head 1 and the second rotating head 2 along the folding direction and locking the open state. When storing, force can be applied to pry the first and second supporting members, thus realizing the opening and folding of the holder, which helps to reduce the length of the holder after storage, making the holder easier to store and carry, and the locking structure is also simple.

[0077] Please see Figures 1-15 This application also provides a portable electronic device holder, including: a first support member 20, a second support member 30, and a folding mechanism 10, which will be described in detail below.

[0078] In this embodiment, the lengths of both the first support member 20 and the second support member 30 are adjustable. The folding mechanism 10 in this embodiment is the same as in the above embodiment, and will not be described again here. The first rotating head 1 of the folding mechanism 10 is fixedly connected to the first support member 20, and the second rotating head 2 is fixedly connected to the second support member 30. This allows the first support member 20 and the second support member 30 to have an open state and a folded state.

[0079] The first support member 20 and the second support member 30 in this application can be any telescopic and adjustable structure. For example, they can be a telescopic structure formed by multiple tubular sub-components (such as the aforementioned sub-rods) nested together, or they can be elastic and telescopic structures with a certain support strength. One end of the first support member 20 is provided with a first rotating head 1, and the other end can be provided with a fixing component 40 for fixing the object being used, such as a clamping structure. One end of the second support member 30 is provided with a second rotating head 2, and the other end can be provided with a support base 50, such as a handle, a three-cornered base, etc. In some embodiments, the first support member 20 and the first rotating head 1, and the second support member 30 and the second rotating head 2, can be an integral structure, or they can be fixedly connected by screws, interference fits, snap-fit ​​connections, riveting, etc. When connected by a connection method, for ease of connection, each rotating head can be provided with a connecting shaft segment for insertion into the support member. In some embodiments, a first rotating head 1 may be provided at one end of the first support member 20, and a second rotating head 2 may be fixedly provided at the other end. Similarly, a second rotating head 2 may be provided at one end of the second support member 30, and a first rotating head 1 may be fixedly provided at the other end. This allows multiple support members to be connected by the folding mechanism 10 to form a multi-layer folding structure. At this time, the bracket is provided with at least two folding mechanisms 10.

[0080] The portable electronic device holder provided in the above embodiment has a first rotating head 1 and a second rotating head 2 rotatably connected to a connecting base 3. The first rotating head 1 is provided with a first engaging portion 101 having multiple teeth, and the second rotating head 2 is provided with a second engaging portion 201 having multiple teeth. The first engaging portion 101 and the second engaging portion 201 engage. In the open state, the teeth of one of the engaging portions 101 and the corresponding tooth grooves of the other engaging portion abut against each other to form an interaction force, thereby restricting the rotation of the first rotating head 1 and the second rotating head 2 along the folding direction and locking the open state. When storing, force can be applied to pry open the first and second supporting members, thus realizing the opening and folding of the holder, which helps to reduce the length of the holder after storage and facilitates the storage and carrying of the holder.

[0081] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
