Description

Technical Field

[0001] This utility model relates to a support frame, and more particularly to a support frame that is easy to fold, has high support strength, and requires little storage space. Background Technology

[0002] When using mobile phones and tablets, users need to hold them to view data and watch videos, but holding them for extended periods can cause hand pain and discomfort. Therefore, the industry has developed various stands to support mobile phones and tablets, freeing up users' hands.

[0003] Taiwanese Utility Model Patent No. M643109 discloses an unfoldable support stand, which unfolds a single-piece multi-layered structure to form a support stand for a mobile phone. However, the support height is insufficient, and users still need to look down to view the device, which can easily cause neck pain after prolonged use. Taiwanese Utility Model Patent No. M628756 discloses a mobile device support stand, which can support the mobile device to a higher position, but both unfolding and folding require manual operation of multiple parts to fully unfold or fold, resulting in poor usability.

[0004] Therefore, how to solve the above problems is the primary issue that this utility model aims to address. Utility Model Content

[0005] The main objective of this invention is to provide a support frame with a support mechanism that can be unfolded or folded into a base. The support mechanism includes a first support, a second support, and a support member that can pivot and fold relative to each other. A locking member controls the pivoting state of the second support relative to the first support, and a limiting rod helps to limit the pivoting angle of the first support so that the first support and the base form a stable support structure. This allows the support frame to have a suitable support height when unfolded, and it can be folded by releasing the positioning of the second support through the locking member. The unfolding and folding operations are simple, and the folded frame is a single plate that occupies little space.

[0006] To achieve the aforementioned objectives, this utility model provides a support frame having a base with a structural surface and a supporting surface arranged opposite to each other. The structural surface is recessed to form a storage space, and a support mechanism pivotally mounted on the structural surface can be stored in the storage space. The support mechanism can change between an extended state and a retracted state, wherein the support mechanism includes:

[0007] A first support, with one end of which is pivotally connected to the structural surface of the base;

[0008] A second bracket, one end of which is pivotally connected to the other end of the first bracket, and a locking member is connected at the pivot point between the second bracket and the first bracket to control the positioning and retraction of the second bracket relative to the first bracket during pivoting.

[0009] At least one limiting rod is pivotally connected between the structural surfaces of the second bracket and the base to limit the pivot angle of the first bracket relative to the base;

[0010] A support member is pivotally connected to the other end of the second bracket for connecting a supported object;

[0011] When the support mechanism is in the retracted state, the first support and the second support can pivot relative to each other and be stored together with the support member in the storage space in a plate-like shape; when the support mechanism is in the extended state, the first support and the second support pivot relative to each other in opposite directions until the locking member positions the second support relative to the first support in the pivoted extended position, and the limiting rod restricts the pivot angle of the first support relative to the base, so that the first support and the second support separate and are in an upward extended state.

[0012] Preferably, the base has two pivot seats symmetrically arranged on one side of its structural surface, and the first bracket has two symmetrically arranged first support legs. The two first support legs are pivotally connected to the two pivot seats, so that the first bracket can swing relative to the base with the two pivot seats as pivot points.

[0013] Preferably, the second bracket has two symmetrically arranged second support legs, which are respectively pivotally connected to the end of the first bracket that is relatively far from the first support leg, so that the second bracket can pivot relative to the first bracket.

[0014] Preferably, a limiting rod is pivotally connected to each side of the second bracket, and the other end of the limiting rod is pivotally connected to one end of the pivot seat near the side of the structural surface, so as to limit the pivot angle of the first bracket.

[0015] Preferably, the first bracket and the second bracket are respectively provided with a first through groove and a second through groove at the pivot point. The locking member has two spring pieces, which are respectively assembled in the first through groove and the second through groove. When the bracket mechanism is in the unfolded state, the first bracket and the second bracket pivot to each other until the first through groove and the second through groove are opposite to each other. The two spring pieces lock each other to position the second bracket. When the bracket mechanism is in the retracted state, pressing the two spring pieces releases the locking, thereby releasing the positioning of the second bracket.

[0016] Preferably, the first bracket has a mating surface and a retractable surface arranged opposite to each other. The retractable surface is provided with a receiving groove for accommodating the second bracket. When the bracket mechanism is in the retracted state, the mating surface of the first bracket is mated with the structural surface of the base, and the second bracket is stored in the receiving groove, so that the first bracket and the second bracket form a plate shape after being retracted, thereby saving storage space.

[0017] Preferably, the second bracket has a self-attracting magnet on its side, and the first bracket has a corresponding magnetic hole for the self-attracting magnet to pass through. When the bracket mechanism is in the retracted state, the self-attracting magnet passes through the magnetic hole and is attracted to the base.

[0018] Preferably, the support member is annular, and the end of the second bracket that is pivotally connected to the support member has a second arc edge to allow the support member to pivot at different angles. The base has a through hole that penetrates the structural surface and the support surface. The end of the first bracket that is pivotally connected to the structural surface has a first arc edge. When the support mechanism is in the retracted state, the second arc edge overlaps with the first arc edge and fits against the edge of the through hole, so that the support member is placed in the through hole. This makes the first bracket, the second bracket, the support member and the base form an integral plate after retraction, thus saving storage space.

[0019] Preferably, the support member is provided with a magnetic material that can magnetically attract a metal connector, the connector being connected to the supported object, allowing the supported object to rotate around the support member.

[0020] Preferably, the support is mounted on the supported object, and the support is detachably pivotally connected to the second bracket.

[0021] The beneficial effects of this utility model are: it has a support mechanism that can be unfolded or folded into the base. The support mechanism has a first support, a second support, and a support member that can pivot and fold relative to each other. The pivoting state of the second support relative to the first support is controlled by a locking member, and the pivoting angle of the first support is limited by a limiting rod to make the first support and the base form a stable support structure. Thus, the support frame has a suitable support height after unfolding, and it can be folded by releasing the positioning of the second support through the locking member. The unfolding and folding operations are simple, and the folded form is a one-piece plate that occupies little space. Attached Figure Description

[0042] 200 support structure Detailed Implementation

[0043] like Figure 1 and Figure 2 As shown, the support frame provided by this utility model has a base 1, which has a structural surface 11 and a support surface 12 arranged opposite to each other. The structural surface 11 is recessed inward to form a storage space 13. A support mechanism 200 that can be stored in the storage space 13 is pivotally mounted on the structural surface 11. The support mechanism 200 can change between an unfolded state and a retracted state.

[0044] In detail, the base 1 has two symmetrically arranged pivot seats 14 on one side of its structural surface 11, and the support mechanism 200 includes a first support 2, a second support 3, a support member 4, and at least one limiting rod 5. The first support 2 is pivotally connected to the two pivot seats 14 by two symmetrically arranged first support legs 21, allowing the first support 2 to swing relative to the base 1 with the two pivot seats 14 as pivot points. The second support 3 is pivotally connected to the end of the first support 2 that is relatively far from the first support legs 21 by two symmetrically arranged second support legs 31, allowing the second support 3 to pivot relative to the first support 2. Through the pivotal structure between the base 1, the first support 2, and the second support 3, the first support 2 and the second support 3 can pivotally expand or contract relative to each other.

[0045] Continuing from the above, a locking member 6 is connected to the pivot point of the first bracket 2 and the second bracket 3. The locking member 6 includes two interlocking spring pieces 61. The first bracket 2 and the second bracket 3 are respectively provided with a first through groove 22 and a second through groove 32 at their pivot points. The two spring pieces 61 are respectively assembled into the first through groove 22 and the second through groove 32. When the bracket mechanism 200 is unfolded, the first bracket 2 and the second bracket 3 pivot in opposite directions until the first through groove 22 and the second through groove 32 are opposite to each other. At this time, the two spring pieces 61 interlock, thereby positioning the second bracket 3. When the bracket mechanism 200 is retracted, pressing the two spring pieces 61 releases the interlocking action, thereby releasing the positioning of the second bracket 3.

[0046] To further explain, a limiting rod 5 is pivotally connected to each of the two sides of the second bracket 3, or a limiting rod 5 is pivotally connected to one side. The other end of the limiting rod 5 is pivotally connected to one end of the pivot seat 14 near the side of the structural surface 11. When the bracket mechanism 200 is in the unfolded state, the locking member 6 has positioned the second bracket 3 so that it cannot pivot relative to the first bracket 2. Since the limiting rod 5 connects the unfolded second bracket 3 to the pivot seat 14, it restricts the first bracket 2 from pivoting toward the structural surface 11 of the base 1. This utility model uses the locking member 6 to lock and the limiting rod 5 to restrict the pivoting, thereby positioning the first bracket 2 and the second bracket 3 in their unfolded positions. The structure is simple and easy to operate.

[0047] Additionally, the base 1 has a through hole 15 penetrating the structural surface 11 and the support surface 12. The first bracket 2 has a first arc edge 23 at one end pivotally connected to the structural surface 11, while the second bracket 3 has a second arc edge 33 at one end pivotally connected to the support member 4. The support member is annular, and its center overlaps with the arc center of the second arc edge 33. The radius of the support member 4 is smaller than the arc radius of the second arc edge 33, allowing the support member 4 to pivot to be on the same horizontal plane as the second arc edge 33. The first bracket 2 has a contact surface 24 and a retractable surface 25 arranged oppositely. The retractable surface 25 also has a receiving groove 26 for receiving the second bracket 3. The side of the second bracket 3 that can contact the retractable surface 25 is provided with a self-attracting magnet 34, and the first bracket 2 is correspondingly provided with a magnetic attraction hole 27 for the self-attracting magnet 34 to pass through. When the support mechanism 200 is in the folded state, the contact surface 24 of the first support 2 is in contact with the structural surface 11 of the base 1, and the second support 3 is housed in the receiving groove 26. The second arc edge 33 overlaps with the first arc edge 23 and is in contact with the edge of the through hole 15. At this time, the support member 4 pivots to be on the same horizontal plane as the second arc edge 33, so that the support member 4 is placed in the through hole 15. The self-attracting magnet 34 passes through the magnetic attraction hole 27 and is magnetically attracted to the base 1, so that the second support 3 is not easy to detach in the folded state. After folding, the first support 2, the second support 3, and the support member 4 are integrated with the base 1 into a single plate, saving storage space.

[0048] The support member 4 is equipped with a magnetic material that can magnetically attract a metal connector 7. In this embodiment, the magnetic material is a magnet. The connector 7 is then connected to the supported object 8, allowing the supported object 8 to rotate around the support member 4.

[0049] In other possible implementations, the support member 4 is installed on the supported object 8, and the support member 4 is detachably pivotally connected to the second bracket 3, so that the user can selectively pivot the supported object 8 to the second bracket 3 according to the usage needs.

[0050] In practical use, this utility model, such as Figure 3 and Figure 4As shown, firstly, the bracket mechanism 200, which is in the retracted state, is separated from the base 1. Simultaneously, the support member 4 is pulled upwards, causing the first bracket 2 and the second bracket 3 to pivot and unfold in opposite directions. When the first bracket 2 and the second bracket 3 pivot to the point where the first through slot 22 and the second through slot 32 are aligned, the two spring pieces 61 of the locking member 6 engage with each other to fix the relative position between the second bracket 3 and the first bracket 2. Meanwhile, the limiting rod 5 pulls the second bracket 3 to limit the pivot angle of the first bracket 2 relative to the base 1. At this point, the bracket mechanism 200 is fully unfolded, and the limiting rod 5, the first bracket 2, and the base 1 form a hypotenuse triangular support structure, improving the overall stability of the unfolded structure. Please refer to the following section. Figure 5 and Figure 6 As shown, the connector 7, such as a metal sheet, is then installed onto a supported object 8. The supported object 8 can be a mobile phone, tablet computer, or its protective case, etc. In this embodiment, the connector 7 is installed onto the back of a mobile phone protective case. Alternatively, it can be as follows... Figure 7 As shown, the connector 7 is installed on a mobile phone. Simply place the support surface 12 of the base 1 on a surface, then attach the side of the supported object 8 with the connector 7 to the support 4, and adjust the support 4 to a suitable viewing angle. Users can also rotate the supported object 8 to different angles before attaching it to the support 4, or attach the supported object 8 to the support 4 and then rotate it.

[0051] After use, simply press the two spring clips 61 of the locking member 6 to release the locking position of the second bracket 3. Under its own weight, the first bracket 2 and the second bracket 3 pivot in opposite directions and retract, so that the first bracket 2 fits against the structural surface 11 of the base 1, while the second bracket 3 is housed in the receiving groove 26 of the first bracket 2. The support member 4 pivots to be on the same horizontal plane as the second arc edge 33 of the second bracket 3 and is housed in the through hole 15 of the base 1. The finally folded support frame is a plate-like structure that fits against the back of the supported object 8, without affecting the overall aesthetics of the supported object 8, and is small and easy to carry.

[0052] The support frame provided by this utility model has the following functions and advantages:

[0053] First, the structure is simple and easy to operate. The structure of this utility model mainly includes a base, a first bracket, a second bracket, and a support member. It has few components and a simple structure. The first bracket, the second bracket, and the support member are pivotally connected to each other. The first bracket and the second bracket are pivotally connected by a locking member composed of two spring pieces to control and position the second bracket. A limiting rod is used to limit the pivot angle of the first bracket. That is, it unfolds into a support frame with a stable structure. The locking member releases the positioning of the second bracket, which can then be folded into the storage space of the base. There is no need to operate multiple components during use, making it simple and easy to operate.

[0054] Secondly, it is small in size and easy to store; after the support frame provided by this utility model is folded up, the first support, the second support and the support components can be closely fitted and stacked together to be stored in the storage space of the base, forming a plate shape, which is small in size and easy to store.

[0055] Third, the application is flexible; the support component of this utility model is a magnetic material such as a magnet, while the connecting component is made of metal that can be magnetically attracted to the magnetic material. Therefore, it can rotate relative to the support component, thereby allowing the supported object to rotate at different angles as needed.
