[0018]The beneficial effects of this application embodiment are as follows: Unlike the prior art, in this application embodiment, the first support rod can rotate relative to the first base rod around the first axis, the second axis, and the third axis, and at least partially, the first support rod can rotate relative to the first base rod around its own axis.

This effectively avoids possible jamming or interference during unfolding, improves the smoothness of the bracket's folding and unfolding, and thus enhances the convenience for users to assemble and store the bracket. Furthermore, by making the top rod detachably connected to the first support assembly and/or the second support assembly, only the top rod needs to be removed. The first and second support assemblies can then rotate relative to the base and move closer to each other, thereby completing the folding of the bracket. There is no need to disassemble each metal rod individually, which simplifies the assembly and storage process of the bracket and improves storage efficiency.

Description
Technical Field
[0001] This application relates to the field of support technology, and in particular to a support and a swing. Background Technology
[0002] With the rise of family outdoor sports, outdoor swings are becoming increasingly popular. In related technologies, swing frames typically consist of multiple metal rods connected and fixed according to a specific structure. When assembling the frame, the rods need to be connected and fixed one by one to form a stable support. When storing the frame, the rods need to be disassembled one by one, making the assembly and disassembly process cumbersome. Summary of the Invention
[0003] The main technical problem solved by the embodiments of this application is to provide a support frame and swing that can simplify the assembly and folding process of the support frame, facilitate the storage of the support frame, and improve the smoothness of the movement of each component during the folding and unfolding process.
[0004] To solve the above-mentioned technical problems, one technical solution adopted in this application embodiment is: providing a bracket, including a base, a first support assembly, a second support assembly, and a top rod. The base includes a seat body, two first bottom rods, and two second bottom rods, each first bottom rod being connected to the seat body, and each second bottom rod being connected to the seat body. The first support assembly includes a first connector and two first support rods, each first support rod being connected to the first connector and rotatably connected to a corresponding first bottom rod. The first support rods are rotatable relative to the first bottom rods around a first axis and a second axis, and at least partially rotatable relative to the first bottom rods around the axis of the first support rod. The support rod can rotate relative to another first support rod around a third axis to adjust the angle between the two first support rods, thereby moving the first support rod closer to or further away from the seat. The first axis is perpendicular to the axis of the first base rod and the axis of the first support rod, the second axis is parallel to the axis of the first base rod, and the third axis is perpendicular to the axis of the first support rod. The second support assembly is spaced apart from the first support assembly, and the seat is located between the first support assembly and the second support assembly. Each second base rod is rotatably connected to the second support assembly. One end of the top rod is connected to the first support assembly, and the other end is connected to the second support assembly, and at least one of the two connections is a detachable connection.
[0005] By utilizing the rotational engagement of the first support rod relative to the first base rod around the first, second, and third axes, as well as the rotational engagement of the first support rod itself, the movements of each component during the folding and unfolding of the bracket are interconnected, reducing the likelihood of jamming. This improves the smoothness of folding and unfolding and lowers the risk of damage to connections due to forced deformation. Furthermore, by making one end of the top rod detachably connected to the first and / or second support components, simply removing the top rod from the first and / or second support components allows them to rotate relative to the base and move closer together. This simplifies the assembly and storage process of the bracket, improving storage efficiency.
[0006] In some embodiments, the first support rod includes a first rod body and a second rod body, which are slidably connected. The first support rod also includes a locking assembly disposed on the first rod body or the second rod body and configured to selectively limit the relative sliding of the first rod body and the second rod body. Through the sliding engagement between the first rod body and the second rod body and the locking of the locking assembly, the length of the first support rod can be adjusted within a certain range, which is beneficial for adjusting the height of the bracket according to usage requirements. Furthermore, the length of the first support rod can be shortened during storage, which helps to reduce the space occupied by the bracket after storage.
[0007] In some embodiments, the second rod is at least partially housed within the first rod, and the first rod is slidably connected to the second rod along the axial direction of the first support rod. The second rod is provided with a locking groove that extends circumferentially along the second rod. When the bracket is in a supported state, the locking assembly is at least partially inserted into the locking groove. By setting the locking groove as an annular or partially annular groove extending circumferentially along the second rod, after the locking assembly is inserted into the locking groove, it limits the relative sliding between the first rod and the second rod along the axial direction of the first support rod, keeping the overall length of the first support rod stable. On the other hand, since the locking groove extends circumferentially, it allows the first rod to rotate relative to the second rod about the axis of the first support rod without dislodging from the locking groove. With this configuration, the first support rod can at least partially rotate about its own axis relative to the first base rod, facilitating the adjustment of the first support rod's posture about its own axis during the unfolding and folding of the bracket. This improves the smoothness of the bracket's unfolding and folding, while reducing the requirements for the rotational freedom of other connections, making the overall structure simpler.
[0008] In some embodiments, the locking assembly includes a locking attachment, an elastic element, and a plug. The locking attachment is disposed on the first rod and has a groove. The plug passes through the groove, and the elastic element is sleeved on the plug. One end of the elastic element abuts against the locking attachment, and the other end abuts against the plug. When the bracket is in a supported state, the plug is at least partially inserted into the locking groove. The elastic element is configured to drive the plug to remain inserted into the locking groove. Driven by the elastic force of the elastic element, the plug can be stably kept inserted into the locking groove without external force, thereby reliably locking the axial relative position between the first rod and the second rod. This significantly improves the stability of the locking, reduces the risk of the first support rod changing length due to accidental disturbance during user use, and further enhances the safety of the bracket.
[0009] In some embodiments, the bracket further includes a first support base, which rotatably connects the first base rod and the first support rod, allowing the first support rod to rotate relative to the first base rod about a first axis and a second axis. The first support base enables the first support rod to rotate relative to the first base rod in both directions about the first and second axes, which helps reduce the number of parts, simplify the structure, and make the folding action more flexible.
[0010] In some embodiments, the first support base is provided with a mounting groove and a limiting protrusion. The mounting groove has a first opening and a second opening facing different directions, and the limiting protrusion is located between the first opening and the second opening. When the first support rod is in a first position relative to the first base rod, the first support rod extends from the first opening; when the first support rod is in a second position relative to the first base rod, the first support rod extends from the second opening. The limiting protrusion is configured to restrict the first support rod from rotating from the first position to the second position. The limiting effect of the limiting protrusion helps to keep the first support rod stably in the first position during use, reducing the risk of the first support rod accidentally entering the second position and improving safety.
[0011] In some embodiments, the second support assembly includes a second connector and two second support rods. Both second support rods are connected to the second connector and rotatably connected to their respective second base rods. Each second support rod is rotatable relative to the second base rod about a fourth axis and a fifth axis. At least a portion of each second support rod is rotatable relative to the second base rod about its own axis, and it is also rotatable relative to the other second support rod about a sixth axis, allowing it to move closer to or further away from the base. The fourth axis is perpendicular to both the axis of the second base rod and the axis of the second support rod. The fifth axis is parallel to the axis of the second base rod, and the sixth axis is parallel to the axis of the top rod. The second support assembly and the first support assembly are symmetrically arranged in their kinematic structure. Together, they ensure smooth movement of the support during deployment and folding, further improving the efficiency of deployment and folding and enhancing overall connection reliability.
[0012] To solve the above-mentioned technical problems, another technical solution adopted in this application embodiment is: providing a bracket, the bracket including a base, a first support component, a second support component, and a top rod. The base includes a seat body, two first bottom rods, and two second bottom rods, all of which are connected to the seat body. The first support component includes two first support rods, one of which is connected to a corresponding first bottom rod and to the other first support rod, forming a first angle between the two first support rods. The second support component includes two second support rods, one of which is connected to a corresponding second bottom rod and to the other second support rod, forming a second angle between the two second support rods. One end of the top rod is connected to the first support component, and the other end is connected to the second support component, with at least one of the connections being detachable. The bracket has a folded state, a first intermediate state, and a supported state. The folded state can be unfolded to the supported state after passing through the first intermediate state. The first angle and the second angle are different in the folded state, the first intermediate state, and the supported state. During the transition from the first intermediate state to the supported state, the first support component moves while the base remains fixed. By switching the bracket to multiple states and moving the first support component relative to the fixed base during the transition from the first intermediate state to the support state, the bracket can be quickly switched between different states, improving assembly and storage efficiency. On the other hand, the base remains fixed during the unfolding process, which helps to maintain stability during the bracket assembly process.
[0013] In some embodiments, two first base rods form a first base angle, and two second base rods form a second base angle. When the bracket is in the supported state, the angles of the first included angle and the second included angle are both smaller than the angles of the first base angle and the second base angle. The angles of the first included angle, the second included angle, the first base angle, and the second base angle when the bracket is in the supported state are all greater than the angles when it is in the folded state. Through this angular relationship, the bracket forms a stable support configuration that is narrower at the top and wider at the bottom when in the supported state, resulting in strong support capacity and high stability. When in the folded state, all angles tend to be smaller, which helps to reduce the space occupied by the bracket after it is stored.
[0014] In some embodiments, two first base rods form a first base angle, and two second base rods form a second base angle. When the bracket is in a supported state, the first support rod intersects with the corresponding first base rod and with another first support rod; the second support rod intersects with the corresponding second base rod and with another second support rod. When the bracket is in a first intermediate state, the first included angle is the same as the first base angle, the second included angle is the same as the second base angle, the first support rod is parallel to the corresponding first base rod and intersects with another first support rod, and the second support rod is parallel to the corresponding second base rod and intersects with another second support rod. When the bracket is in a folded state, the first support rod, the second support rod, the first base rod, and the second base rod are parallel. Through the positional relationships between the rods in the above three states, the bracket has the characteristics of stable support, transition, and compact storage in different states, which facilitates switching in different application scenarios.
[0015] In some embodiments, the support also includes a second intermediate state, after which the folded state can be unfolded into a supported state via the first intermediate state and the second intermediate state. When the support is in the second intermediate state, the first included angle is smaller than the first bottom angle, the second included angle is smaller than the second bottom angle, the first support rod intersects with the corresponding first bottom angle, and intersects with another first support rod; the first support rod and the corresponding first bottom rod form a first plane, and the first plane in the second intermediate state intersects with the first plane in the supported state. By setting the second intermediate state, the spatial position of the first plane formed by the first support rod and the first bottom rod is different in the second intermediate state and the supported state, which is beneficial for avoiding obstacles by rotating the first support rod around the second axis during the unfolding process, improving the smoothness of the support unfolding process, and reducing the risk of jamming or interference between the rods.
[0016] In some embodiments, the first and second support rods are telescopically connected. When the support is in a second intermediate state, the first and second support rods are in a retracted state, and when the support is in a supported state, the first and second support rods are in an extended state. This telescopic connection allows the retracted state in the second intermediate state to reduce the space occupied by other rods, and the extended state in the supported state to increase the distance between the top rod and the ground, thus improving the height adaptability of the support during use.
[0017] To solve the above-mentioned technical problems, another technical solution adopted in this application embodiment is: to provide a swing, including a seat, at least two mounting mechanisms and the above-mentioned bracket, both mounting mechanisms are connected to a top rod, one mounting mechanism is connected to one end of the seat, and the other mounting mechanism is connected to the other end of the seat.
[0018] The beneficial effects of this application embodiment are as follows: Unlike the prior art, in this application embodiment, the first support rod can rotate relative to the first base rod around the first axis, the second axis, and the third axis, and at least partially, the first support rod can rotate relative to the first base rod around its own axis. This allows the first included angle and the first base angle of the bracket to change during the unfolding process, ensuring that the support rods and their corresponding base rods maintain continuous movement and coordinated posture at each stage of the unfolding process. This effectively avoids possible jamming or interference during unfolding, improves the smoothness of the bracket's folding and unfolding, and thus enhances the convenience for users to assemble and store the bracket. Furthermore, by making the top rod detachably connected to the first support assembly and / or the second support assembly, only the top rod needs to be removed. The first and second support assemblies can then rotate relative to the base and move closer to each other, thereby completing the folding of the bracket. There is no need to disassemble each metal rod individually, which simplifies the assembly and storage process of the bracket and improves storage efficiency. Attached Figure Description

[0022] To facilitate understanding of this application, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is described as "fixed to" another element, it can be directly on the other element, or one or more intermediate elements may exist between them. When an element is described as "connected" to another element, it can be directly connected to the other element, or one or more intermediate elements may exist between them. The terms "upper," "lower," "inner," "outer," "vertical," "horizontal," etc., used in this specification indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0023] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the application. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.
[0024] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.
[0025] With the rise of family outdoor activities, outdoor swings are becoming increasingly popular. In related technologies, swing frames typically consist of multiple metal rods connected and secured according to a specific structure. Assembling the frame requires connecting and securing each metal rod individually to form a stable support. Conversely, storing the frame necessitates disassembling each metal rod individually, a tedious process that consumes considerable time and effort. Furthermore, the scattered metal rods pose a risk of loss or scattering during transportation or storage, hindering quick setup and convenient storage for outdoor use.
[0026] To at least partially solve the above problems, this application provides a support frame and a swing that can simplify the assembly and folding process of the support frame and improve the smoothness of the unfolding and folding process.
[0027] The technical solution of this application is described below.
[0028] Example 1 Please see Figure 1 , Figure 2 and Figure 3This embodiment provides a bracket 100, which can be applied to outdoor products with suspension requirements such as swings and rocking chairs. The bracket 100 includes a base 1, a first support component 2, a second support component 3, and a top rod 4. The base 1 includes a seat body 11, two first bottom rods 12, and two second bottom rods 13. Each first bottom rod 12 is connected to the seat body 11, and each second bottom rod 13 is connected to the seat body 11. The first support component 2 and the second support component 3 form a three-dimensional support on both sides of the base 1. The top rod 4 is generally long and forms a lateral connection between the first support component 2 and the second support component 3, providing a suspension position for the hanging mechanism 200 and other suspension components. The second support component 3 and the first support component 2 are spaced apart. The seat body 11 is located between the first support component 2 and the second support component 3, and each second bottom rod 13 is rotatably connected to the second support component 3. One end of the top rod 4 is connected to the first support component 2, and the other end of the top rod 4 is connected to the second support component 3, with at least one of the connections being detachable. When the top rod 4 is separated from the first support assembly 2 or the second support assembly 3, the first support assembly 2 and the second support assembly 3 can rotate relative to the base 1 to fold the bracket 100.
[0029] In this embodiment, simply removing the top rod 4 from the first support assembly 2 or the second support assembly 3 allows the first support assembly 2 and the second support assembly 3 to rotate relative to the base 1 and move closer to each other, thereby completing the folding of the bracket 100. This eliminates the need to disassemble each metal rod on the bracket 100 individually, simplifying the assembly and storage process and improving storage efficiency.
[0030] It is worth noting that the first support component 2 can be directly rotatably connected to the base 1, or it can be indirectly rotatably connected to the base 1 through one or more intermediate components (such as the first base rod 12 described below). This embodiment does not impose any restrictions on this. The rotatable connection between the second support component 3 and the base 1 is similar.
[0031] For base 1 mentioned above, please refer to [link / reference]. Figure 1 , Figure 2 and Figure 3 The base 1 includes a seat body 11, two first base rods 12, and two second base rods 13. The seat body 11 is located in the middle of the base 1 and serves as the rotatable connection base for the first base rods 12 and the second base rods 13. Both the first base rods 12 and the second base rods 13 are integrally long rods, extending to both sides to support the first support assembly 2 and the second support assembly 3. One end of each first base rod 12 is rotatably connected to the seat body 11, one end of the first support assembly 2 is rotatably connected to the two first base rods 12, one end of the second base rod 13 is rotatably connected to the seat body 11, and one end of the second support assembly 3 is rotatably connected to the two second base rods 13.
[0032] In some embodiments, the base 1 can switch between an unfolded state and a folded state. In the folded state, the distance between the end of the first base rod 12 away from the base 11 and the end of the second base rod 13 away from the base 11 is shorter than the distance in the unfolded state. In this embodiment, each of the first base rods 12 and each of the second base rods 13 can rotate relative to the base 11, so that the base 1 itself has a folding capability. When stored, the first base rods 12 and the second base rods 13 can rotate around the base 11 and move closer to each other, which helps to reduce the lateral dimension of the bracket 100 after storage and further reduce the space occupied.
[0033] In some embodiments, the lower end of the first support component 2 is connected to the first base rod 12, such as... Figure 1 As shown, at this time, the end of the first base rod 12 away from the seat 11 is used to contact the bottom surface. In some alternative embodiments, please refer to... Figure 11 The first support component 2 is connected to the end of the first base rod 12 away from the seat 11. At this time, the lower end of the first support rod 22 of the first support component 2 is used to abut against the bottom surface.
[0034] In some embodiments, please refer to Figure 12 Along the vertical direction X, the distance between the end of the first bottom rod 12 furthest from the base 11 and the top rod 4 is L1, and the distance between the base 11 and the top rod 4 is L2, where L1 > L2. L1 > L2 means that the position of the base 11 in the vertical direction X is higher than the end of the first bottom rod 12 furthest from the base 11; that is, the bottom of the base 11 is higher than the ground when in use, with a certain height difference between them. This design allows the base 11 to be lifted off the ground on uneven outdoor surfaces, reducing the risk of interference between the base 11 and the ground, improving the adaptability of the bracket 100 to the usage environment, and enhancing the overall support stability of the base 1.
[0035] It is worth noting that the shapes of the first base rod 12 and the second base rod 13 are not specifically limited. For example, they can be straight rods, or they can be L-shaped, arc-shaped, or other shapes. When the first base rod 12 and the second base rod 13 are L-shaped or arc-shaped, the first base rod 12 and the second base rod 13 themselves can have a certain height variation, thereby raising the seat body 11 of the base 1 to a position above the ground, which helps to reduce the risk of interference between the seat body 11 and the ground.
[0036] In some embodiments, please refer to Figure 6 The first base rod 12 has a foot 123 at the end away from the base 11, and the foot 123 is in direct contact with the ground. The foot 123 has a through groove 1231 that passes through the foot 123 in a roughly vertical direction. When the bracket 100 is used outdoors, ground stakes or other fixing structures can be inserted into the through groove 1231 and then into the ground to fix the bracket 100, thereby improving the stability of the bracket 100.
[0037] In some embodiments, please refer to Figure 2 , Figure 13 and Figure 14 The base 11 is provided with at least two receiving slots 111, and there are at least two first base rods 12, with one end of each first base rod 12 being received in one receiving slot 111. Each receiving slot 111 has a contact wall 112, two side surfaces 113, and a top surface 114. The two side surfaces 113 are located on opposite sides of the first base rod 12, respectively, and are used to restrict the rotation of the first base rod 12 about its own axis within the receiving slot 111 and its displacement in a direction perpendicular to the axial direction of the first base rod 12. The contact wall 112 is located above the first base rod 12 and is used to abut against the outer peripheral wall of the first base rod 12 when the base 1 is in the unfolded state, thereby bearing the supporting force from the first base rod 12. The top surface 114 is located above the first base rod 12, on the side of the contact wall 112 opposite to the first base rod 12. When the base 1 is in the unfolded state, the outer peripheral wall of the first base rod 12 abuts against the contact wall 112, and since the top surface 114 is located on the side of the contact wall 112 away from the first base rod 12, the top surface 114 can avoid the first base rod 12, so that the first base rod 12 can rotate relative to the base body 11.
[0038] Through the limiting engagement of the receiving groove 111 and the contact wall 112, under the gravity of the base 1, the outer peripheral wall of the first bottom rod 12 remains in contact with the corresponding contact wall 112, which helps to limit the position of the first bottom rod 12 relative to the seat body 11 and improves the support stability of the base 1 in the unfolded state. In addition, the limiting of the first bottom rod 12 by the receiving groove 111 and the contact wall 112 also helps to keep the seat body 11 above the ground in the vertical direction X, further reducing the risk of interference between the seat body 11 and the ground.
[0039] In some embodiments, during the process of switching the base 1 from an unfolded state to a retracted state, both the first base rod 12 and the second base rod 13 rotate relative to the base 11 in the direction below the base 11 (i.e., away from the top surface 114). Finally, in the retracted state, both the first base rod 12 and the second base rod 13 are approximately vertically positioned, meaning their axial directions are approximately parallel to the vertical direction X. This arrangement, with the first base rod 12 and the second base rod 13 extending vertically in the retracted state, helps reduce the space occupied by the base 1 in the horizontal direction, facilitating the transportation and storage of the bracket 100 after it has been retracted.
[0040] In some embodiments, please refer to Figure 2The base 1 also includes a handle 50, which is connected to the base body 11 and located on the side of the base body 11 near the top rod 4. The handle 50 is generally ring-shaped or strip-shaped for the user to grip. When the user lifts the handle 50, the first bottom rod 12 and the second bottom rod 13 rotate around the base body 11 under the action of gravity and retract towards the base body 11, thereby driving the entire bracket 100 into a folded state. By providing the handle 50, it is beneficial to simplify the user's folding operation of the bracket 100 and facilitate the extraction and handling of the folded bracket 100.
[0041] In some embodiments, please refer to Figure 1 From the end of the first support component 2 closest to the first base rod 12 to the end of the first support component 2 furthest from the first base rod 12, the distance between the first support component 2 and the second support component 3 gradually decreases. That is, the lower ends of the first support component 2 and the second support component 3 are far apart, while their upper ends are close together, forming a support structure that is wider at the bottom and narrower at the top. In this embodiment, the large lower distance and small upper distance between the first support component 2 and the second support component 3 lowers the center of gravity of the bracket 100, which helps improve the stability of the bracket 100 in use. In other embodiments, the lower ends of the first support component 2 and the second support component 3 may be close together, while their upper ends are far apart, forming a support structure that is wider at the top and narrower at the bottom.
[0042] For the first support component 2, please refer to Figure 1 , Figure 2 and Figure 3 The first support assembly 2 includes a first connector 21 and two first support rods 22. Both first support rods 22 are connected to the first connector 21 and rotatably connected to their respective first base rods 12. Specifically, one first support rod 22 is connected to one of the first base rods 12, and one end of the other first support rod 22 is connected to the other first base rod 12. Both first support rods 22 are connected to the first connector 21. One end of the top rod 4 is detachably connected to the first connector 21, and the two first support rods 22 can rotate towards or away from each other.
[0043] By setting two first support rods 22, in use, the two first support rods 22 and the two first bottom rods 12 form a stable support structure, which helps to improve the stability of the bracket 100. In addition, the two first support rods 22 can rotate in a direction that moves closer or further away from each other, so that after the top rod 4 is removed, the two first support rods 22 can move closer to each other, which helps to improve the folding efficiency of the bracket 100. It is understood that the first support component 2 is not limited to two first support rods 22. In other embodiments, it can also be three, four, etc. Among them, three first support rods 22 should be understood as including two first support rods 22 plus one more first support rod 22.
[0044] In some embodiments, the two first support rods 22 can rotate about the axis of the top rod 4, so that the two first support rods 22 can move closer to each other or further away from each other. In some optional embodiments, the two first support rods 22 can also rotate about other axes relative to the first connector 21, which is not limited in this application.
[0045] In some embodiments, please refer to Figure 1 , Figure 5 and Figure 10 The first support rod 22 is rotatable relative to the first base rod 12 about a first axis N, a second axis H, and a third axis M, and at least partially rotatable relative to the first base rod 12 about its own axis. The first axis N is perpendicular to both the axis of the first base rod 12 and the axis of the first support rod 22; the second axis H is parallel to the axis of the first base rod 12; the first support rod 22 rotates about the third axis M to adjust the angle between the two first support rods 22; and the third axis M is perpendicular to the axis of the first support rod 22, optionally parallel to the axis of the top rod 4. The two first support rods 22 can rotate relative to each other about the third axis M, allowing the ends of the two first support rods 22 away from the first base rod 12 to move closer to or further away from the base 11.
[0046] During the folding or unfolding of the bracket 100, the angle between the first support rod 22 and the first base rod 12, as well as the angle between the two first support rods 22, will change. Furthermore, the first support rod 22 needs to rotate relative to the first base rod 12 around its own axis at least partially. Therefore, through the rotational coordination of the first support rod 22 relative to the first base rod 12 around the first axis N, the second axis H, and the third axis M, as well as the rotational coordination in the direction of the first support rod 22's own axis, the movement of each component of the bracket 100 is interconnected during the folding and unfolding process, making it less prone to jamming. This helps to improve the smoothness of the folding and unfolding of the bracket 100 and reduces the risk of damage to the joints due to forced deformation.
[0047] It is worth noting that the first support rod 22 can be directly rotatably connected to the first base rod 12, or it can be indirectly connected to the first base rod 12 through one or more intermediate components (such as the first support seat 5 described below). For example, it can also be connected to the seat body 11 by setting a rod sleeve on the first base rod 12. This embodiment does not limit this.
[0048] In some embodiments, please continue reading Figure 1When the base 1 is in the unfolded state, the distance between the two first support rods 22 gradually decreases from the end of the first support rod 22 away from the first connector 21 to the end of the first support rod 22 closer to the first connector 21. In other words, the two first support rods 22 also form a configuration that is wider at the bottom and narrower at the top, which helps to further improve the overall stability of the bracket 100.
[0049] In some embodiments, please refer to Figure 1 , Figure 15 and Figure 16 The first support rod 22 includes a first rod body 221, a second rod body 222, and a locking assembly 223. The first rod body 221 is generally long and tubular or long and rod-shaped, while the second rod body 222 is generally long and rod-shaped. The diameter of the second rod body 222 is adapted to the inner diameter of the first rod body 221, so that the second rod body 222 is at least partially housed within the first rod body 221. The first rod body 221 is slidably connected to the second rod body 222 along the axial direction of the first support rod 22, thereby achieving length extension and retraction. The end of the second rod body 222 away from the first rod body 221 is connected to the first connector 21, and the end of the first rod body 221 away from the second rod body 222 is connected to the first base rod 12. The locking assembly 223 is disposed on the first rod body 221 or the second rod body 222 and is configured to selectively limit the relative sliding of the first rod body 221 and the second rod body 222. When the locking assembly 223 is in the released state, the first rod 221 can slide relative to the second rod 222 to adjust the length of the first support rod 22; when the locking assembly 223 is in the locked state, the first rod 221 and the second rod 222 can be locked together.
[0050] In this embodiment, through the sliding engagement between the first rod 221 and the second rod 222 and the locking assembly 223, the length of the first support rod 22 can be adjusted within a certain range, which is beneficial for adjusting the height of the bracket 100 according to usage requirements. Shortening the length of the first support rod 22 during storage helps to reduce the space occupied by the bracket 100 after storage.
[0051] In some embodiments, the first rod 221 is at least partially housed within the second rod 222, and the first rod 221 is slidably connected to the second rod 222 along the axial direction of the first support rod 22. The second rod 222 is provided with a locking groove 2221, which extends circumferentially along the second rod 222. When the bracket 100 is in a supported state, the locking assembly 223 is at least partially inserted into the locking groove 2221. By setting the locking groove 2221 as an annular or partially annular groove extending circumferentially along the second rod 222, after the locking assembly 223 is inserted into the locking groove 2221, on the one hand, it limits the relative sliding between the first rod 221 and the second rod 222 along the axial direction of the first support rod 22, keeping the overall length of the first support rod 22 stable; on the other hand, since the locking groove 2221 extends circumferentially, it allows the first rod 221 to rotate relative to the second rod 222 about the axis of the first support rod 22 without dislodging from the locking groove 2221.
[0052] With this configuration, at least part of the first support rod 22 (i.e., the first rod body 221 connected to the first connector 21) can rotate relative to the first base rod 12 around its own axis. This facilitates the adjustment of the posture of the first support rod 22 around its own axis during the unfolding and folding of the bracket 100, which helps to improve the smoothness of the folding and unfolding of the bracket 100. At the same time, it reduces the requirements for the rotational freedom of other connections, making the overall structure simpler.
[0053] In some embodiments, the locking assembly 223 includes a locking attachment 2231, an elastic element 2232, and an insert 2233. The locking attachment 2231 is disposed on the second rod 222 and has a groove 22311. The insert 2233 passes through the groove 22311, and the elastic element 2232 is sleeved on the insert 2233. One end of the elastic element 2232 abuts against the locking attachment 2231, and the other end of the elastic element 2232 abuts against the insert 2233. When the bracket 100 is in a supported state, the insert 2233 is at least partially inserted into the locking groove 2221, and the elastic element 2232 is configured to drive the insert 2233 to remain inserted in the locking groove 2221.
[0054] In this embodiment, driven by the elastic force of the elastic element 2232, the plug 2233 can be stably inserted into the locking groove 2221 without external force, thus ensuring that the axial relative position between the first rod 221 and the second rod 222 is always reliably locked. This significantly improves the stability of the locking and reduces the risk of the first support rod 22 changing in length due to accidental disturbance during user use, further enhancing the safety of the bracket 100. When the user needs to unlock the bracket to adjust the length of the first support rod 22 or to store the bracket 100, only an external force is needed to overcome the elastic force of the elastic element 2232 on the plug 2233, causing the plug 2233 to exit the locking groove 2221 along the slide groove 22311. The operation is simple and requires no additional tools.
[0055] It is understood that the elastic element can be, for example, a coil spring, a sheet, a rubber ring, or other elastic element with rebound properties, and this embodiment does not specifically limit it.
[0056] It is worth noting that the structure of the locking component 223 is not limited to the above-described cases. For example, in some embodiments, please refer to [link to relevant documentation]. Figure 17 The locking assembly 223 can be a stud. The first rod 221 is provided with a screw hole 2211. The stud is screwed into the screw hole 2211. By adjusting the depth of the stud screwed into the screw hole 2211, a part of the stud can be inserted into the locking groove 2221, so that the axial relative position between the first rod 221 and the second rod 222 is always reliably locked.
[0057] It is worth noting that during the folding process, the first support rod 22 needs to rotate relative to the first base rod 12 in two directions: on the one hand, it rotates slightly around the axis of the first base rod 12 to avoid changes in the angle between the first support rod 22 and the first base rod 12 around the axis of the first base rod 12 during folding; on the other hand, it rotates significantly around the axis that is horizontal and perpendicular to the first base rod 12 to bring the first support rod 22 closer to the first base rod 12, thereby achieving folding. If two independent hinge structures are used to achieve the above rotation, the number of parts will be large and the structure will be complex.
[0058] To at least partially address the above problems, in some embodiments, please refer to Figure 4 and Figure 5 The bracket 100 also includes a first support base 5, which serves as a rotatable connection between the first support rod 22 and the first base rod 12. The first support base 5 rotatably connects the first base rod 12 and the first rod body 221, allowing the first support rod 22 to rotate relative to the first base rod 12 around the first axis N and the second axis H. The first support base 5 enables the first support rod 22 to rotate relative to the first base rod 12 in both directions around the first axis N and the second axis H, which helps reduce the number of parts, simplify the structure, and make the folding action more flexible.
[0059] In some embodiments, please refer to Figure 1 , Figure 5 and Figure 8 The first support base 5 is located at the end of the first base rod 12 away from the base body 11. The first support base 5 is provided with a mounting groove 511 and a limiting protrusion 512. The mounting groove 511 is used to accommodate the end of the second rod 222. The mounting groove 511 has a first opening 513 and a second opening 514 facing different directions. The limiting protrusion 512 is located between the first opening 513 and the second opening 514. The limiting protrusion 512 is generally a raised block or rib structure. When the second rod 222 is in the first position relative to the first base rod 12, the first support rod 22 extends out from the first opening 513. At this time, the top rod 4 can be connected and fixed to the first connecting member 21, thereby completing the assembly of the bracket 100. When the first support rod 22 is in the second position relative to the first base rod 12, the first support rod 22 extends out from the second opening 514. At this time, the first support rod 22 is approximately parallel to the first base rod 12. At this time, the bracket 100 can be folded. The limiting protrusion 512 is configured to restrict the second rod 222 from rotating from the first position to the second position, and may also restrict the first support rod 22 from rotating from the second position to the first position.
[0060] In this embodiment, the limiting protrusion 512 limits the first support rod 22 in the use state (i.e., the support state described below), making it difficult for it to slide from the first position to the second position. This helps reduce the risk of the first support rod 22 accidentally switching to the storage position and improves the safety of the bracket 100 during use.
[0061] In some embodiments, the limiting protrusion 512 and the first support base 5 are integrally formed, for example, by injection molding, die casting, or other methods. The first opening 513 and the second opening 514 are separated by the limiting protrusion 512, and the space at the limiting protrusion 512 for the first support rod 22 to pass through is smaller than the diameter of the first support rod 22. Thus, when the first support rod 22 rotates from the first position to the second position, the first support rod 22 is blocked by the limiting protrusion 512 and cannot pass through the limiting protrusion 512, thereby being restricted to the first position; conversely, when the first support rod 22 rotates from the second position to the first position, the first support rod 22 is blocked by the limiting protrusion 512 and cannot pass through the limiting protrusion 512, thereby being restricted to the second position.
[0062] In some embodiments, the first support 5 is a plastic support, such as one-piece injection molded from polypropylene, nylon, or other engineering plastics. Because plastic materials have a certain degree of elasticity, the first support 5 can undergo elastic deformation when subjected to force. Therefore, when the torque applied to the first support rod 22 exceeds a predetermined value, the plastic at the limiting protrusion 512 can undergo temporary elastic deformation, thereby allowing the first support rod 22 to rotate past the limiting protrusion 512 from the first position to the second position, or from the second position to the first position, facilitating the assembly and folding of the bracket 100.
[0063] It is worth noting that when subjected to a torque exceeding a preset value (e.g., 50 N·m), the first support rod 22 can overcome the obstruction of the limiting protrusion 512, thereby rotating from the first position to the second position, or from the second position to the first position, thereby assembling or folding the bracket 100.
[0064] In some embodiments, please refer to Figure 5 , Figure 7 and Figure 8 The first support base 5 includes a first connecting portion 52 and a first mounting portion 51. One end of the first mounting portion 51 is connected to the first connecting portion 52. The first mounting portion 51 is used to mount and constrain the end of the second rod 222, and the first connecting portion 52 is used to establish a connection with the first bottom rod 12. A mounting groove 511 and a limiting protrusion 512 are provided in the first mounting portion 51. The first bottom rod 12 passes through the first connecting portion 52. The included angle α between the first connecting portion 52 and the first mounting portion 51 is less than 90°, so that when the second rod 222 is in the first position, the second rod 222 is inclined relative to the ground. Through the included angle of less than 90° between the first connecting portion 52 and the first mounting portion 51, the second rod 222 is inclined at a certain angle relative to the ground in the first position, which is conducive to forming the stable configuration of being wider at the bottom and narrower at the top as described above, and improving the stability of the bracket 100.
[0065] In some embodiments, please refer to Figure 5 and Figure 6 The first support base 5 is provided with a first connecting hole 521, and the first base rod 12 is provided with a first through hole 121. The first connecting hole 521 communicates with the first through hole 121. The bracket 100 also includes a first plug-in member 6, which passes through the first connecting hole 521 and the first through hole 121 along one of the radial directions of the first base rod 12. In the circumferential direction of the first base rod 12, at least one of the first connecting hole 521 and the first through hole 121 has a size larger than the diameter of the first plug-in member 6.
[0066] In this embodiment, by ensuring that at least one of the first connecting hole 521 and the first through hole 121 in the circumferential direction is larger than the diameter of the first plug-in 6, a clearance fit is formed, allowing the first support base 5 to rotate slightly within a small angle range around the axis of the first base rod 12 (i.e., the direction of the second axis H). During the folding process of the bracket 100, this clearance provides space for the small-angle rotation of the second rod 222 relative to the first base rod 12, which helps to improve the smoothness of folding and reduces the risk of damage to the connecting components due to stress concentration.
[0067] In some embodiments, in the circumferential direction of the first base rod 12, the size of the first connecting hole 521 is larger than the diameter of the first plug 6.
[0068] In some embodiments, in the circumferential direction of the first base rod 12, the size of the first through hole 121 is larger than the diameter of the first connector 6.
[0069] In some embodiments, in the circumferential direction of the first base rod 12, the dimensions of the first connecting hole 521 and the first through hole 121 are both larger than the diameter of the first plug 6.
[0070] In some embodiments, the first through hole 121 is configured as an oblong hole (also called a long oval hole or elongated hole), meaning that the dimension of the first through hole 121 in the circumferential direction of the first base rod 12 is larger than the diameter of the first connector 6, while the dimension in the axial direction of the first base rod 12 is substantially the same as the diameter of the first connector 6. The dimension of the first connecting hole 521 is substantially the same as the diameter of the first connector 6. With this configuration, the first connector 6 is constrained in the axial direction by both the first through hole 121 and the first connecting hole 521. In the circumferential direction, since the first through hole 121 is oblong and larger than the diameter of the first connector 6, the first support 5 can rotate slightly relative to the first base rod 12 around the second axis H, further improving the smoothness of the folding process.
[0071] In some embodiments, the first connector 6 may be a pin.
[0072] In some embodiments, please refer to Figure 1 , Figure 9 and Figure 10The bracket 100 also includes a first fastener 7. One end of the push rod 4 is provided with a first stud 41, which is cylindrical with external threads. The first connecting member 21 includes a first connecting body 211 and a second connecting body 212, wherein one first support rod 22 is connected to the first connecting body 211 and the other first support rod 22 is connected to the second connecting body 212. The first connecting body 211 is provided with a first rotating hole 2111, and the second connecting body 212 is provided with a second rotating hole 2121. The first stud 41 passes through the first rotating hole 2111 and the second rotating hole 2121, and the first fastener 7 is screwed to the first stud 41. When the first fastener 7 is locked, the push rod 4 and the first connecting member 21 are relatively fixed, and the bracket 100 is in use. After the first fastener 7 is loosened and the first stud 41 is pulled out from the first rotating hole 2111 and the second rotating hole 2121, the push rod 4 is separated from the first connecting member 21. In this embodiment, the first stud 41 and the first fastener 7 are used to achieve detachable fixing between the push rod 4 and the first connector 21, which is simple in structure and easy to operate.
[0073] It is worth noting that the connection method between the first support rod 22 and the first connecting body 211 (or the second connecting body 212) is not specifically limited. For example, it can be a welding connection, integral molding, bolt connection, riveting connection, etc. This application does not limit this connection method.
[0074] In some embodiments, please refer to Figure 1 , Figure 2 and Figure 9The second support assembly 3 has a similar structure to the first support assembly 2, and there are two second bottom rods 13. The second support assembly 3 includes a second connector 31 and two second support rods 32. The second connector 31 is located at the upper end of the second support assembly 3 and has a similar structure to the first connector 21. The second connector 31 includes a third connector 311 and a fourth connector 312. The third connector 311 is provided with a third rotating hole 3111, and the fourth connector 312 is provided with a fourth rotating hole 3121. The two second support rods 32 are respectively connected to the third connector 311 and the fourth connector 312. The structure of the second support rods 32 is similar to that of the first support rod 22, and may also include a sliding fit between the rods and a locking structure of a locking member to achieve length adjustment. The second support rods 32 and the second bottom rods 13 are connected by a second support seat 8, which has a similar structure to the first support seat 5. The bracket 100 also includes a second plug-in member 9 and a second fastener 10. The second connector 9 has a similar structure to the first connector 6. The second connector 9 passes through the second support base 8 and the second base rod 13 in the radial direction of the second base rod 13. The top rod 4 is provided with a second stud 42 at the end away from the first stud 41. The second stud 42 passes through the third rotating hole 3111 and the fourth rotating hole 3121 of the second connector 31. The second fastener 10 is screwed to the second stud 42.
[0075] In other words, the second support component 3 and the first support component 2 are arranged symmetrically in structure and function, and together with the base 1, they form a stable three-dimensional support configuration. For details regarding the specific structure and function of the second support component 3, the second support base 8, and the second base rod 13, as well as their connection methods, please refer to the first support component 2, the first support base 5, and the first base rod 12; this application will not elaborate further on these aspects.
[0076] In some embodiments, please refer to Figure 1 and Figure 9 The second support rod 32 is rotatable relative to the second base rod 13 about the fourth axis F and the fifth axis K. At least partially, the second support rod 32 is rotatable relative to the second base rod 13 about its own axis, and it is also rotatable relative to another second support rod 32 about the sixth axis G, allowing it to move closer to or further away from the base 11. The fourth axis F is perpendicular to both the axis of the second base rod 13 and the axis of the second support rod 32; the fifth axis K is parallel to the axis of the second base rod 13; and the sixth axis G is parallel to the axis of the top rod 4. The second support assembly 3 and the first support assembly 2 are symmetrically arranged in their kinematic structure. Together, they ensure the smooth movement of the support 100 during unfolding and folding, further improving the unfolding and folding efficiency of the support 100 and enhancing the overall connection reliability.
[0077] Specifically, the second support rod 32 includes a third rod body 321 and a fourth rod body 322. The third rod body 321 is connected to the second support base 8, and the fourth rod body 322 is connected to the second connecting member 31. The fourth rod body 322 is at least partially housed within the third rod body 321. The third rod body 321 is slidably connected to the fourth rod body 322 along the axial direction of the second support rod 32, thereby achieving length extension and retraction. The third rod body 321 can rotate relative to the fourth rod body 322 about the axis of the second support rod 32 relative to the second base rod 13 (i.e., the second support rod 32 can at least partially rotate about its own axis relative to the second base rod 13).
[0078] In some embodiments, the connection between the top rod 4 and the first support assembly 2, and between the top rod 4 and the second support assembly 3, are both detachable, so that the bracket 100 can be folded when the top rod 4 is detached from the first support assembly 2 and the second support assembly 3. It is understood that of the two connections between the top rod 4 and the first support assembly 2, and between the top rod 4 and the second support assembly 3, one is a detachable connection and the other is a rotatable connection. Figure 12 For example, when one end of the push rod 4 is detached from the first support assembly 2, the other end of the push rod 4 can move relative to the second support assembly 3 along... Figure 12 The bracket 100 is retracted by rotating it in the Y direction.
[0079] In some embodiments, please refer to Figure 1 , Figure 2 and Figure 3 The bracket 100 has a supported state, a first intermediate state, and a folded state. Figure 1 This shows a schematic diagram of the structure when the support 100 is in the supported state. Figure 2 This shows a schematic diagram of the structure when the support 100 is in the first intermediate state. Figure 3 A schematic diagram of the support 100 in the folded state is shown. The folded state can unfold to the supported state after passing through a first intermediate state, and conversely, the supported state can fold back to the folded state after passing through the first intermediate state. When the support 100 is in the folded state, the base 1 is in the stored state; when the support 100 is in the supported state and the first intermediate state, the base 1 is in the unfolded state.
[0080] Please refer to Figure 1A first included angle β1 is formed between the two first support rods 22, a second included angle β2 is formed between the two second support rods 32, a first base angle θ1 is formed between the two first base rods 12, and a second base angle θ2 is formed between the two second base rods 13. The first included angle β1 and the second included angle β2 are different in the folded state, the first intermediate state, the second intermediate state, and the supported state, thus allowing the bracket 100 to switch between different states through angle changes. Furthermore, during the transition from the first intermediate state to the supported state, the first support component 2 moves while the base 1 remains fixed. By keeping the base 1 fixed during the transition from the first intermediate state to the supported state, it is beneficial to maintain the stability of the bottom support during the assembly of the bracket 100 and to allow the operator to concentrate on adjusting the position and posture of the first support component 2, thereby improving the efficiency and accuracy of assembly.
[0081] In some embodiments, when the bracket 100 is in a supported state, please refer to Figure 1 The angles of the first included angle β1 and the second included angle β2 are both smaller than the angles of the first base angle θ1 and the second base angle θ2. Furthermore, when the bracket 100 is in the supported state, the angles of the first included angle β1, the second included angle β2, the first base angle θ1, and the second base angle θ2 are all greater than the angles in the folded state.
[0082] It should be noted that the first included angle β1, the second included angle β2, the first base angle θ1, and the second base angle θ2 change during the process of the bracket 100 switching from the folded state to the supported state (or vice versa), and the relative magnitudes of the first included angle β1 and the first base angle θ1, and the relative magnitudes of the second included angle β2 and the second base angle θ2 also change with the state switch (as described in detail below). Based on the above changes in angles, during the folding and unfolding of the bracket 100, the first support rod 22 needs to rotate relative to the first base rod 12 relative to the second axis H (i.e., the direction parallel to the axis of the first base rod 12) to avoid positional misalignment of the two first support rods 22 and the two first base rods 12 due to differences in included angles in different states; similarly, the second support rod 32 needs to rotate relative to the second base rod 13 relative to the fifth axis K (i.e., the direction parallel to the axis of the second base rod 13).
[0083] This configuration ensures that, in the supported state, the bracket 100 forms a stable support structure that is narrow at the top and wide at the bottom due to β1 < θ1 and β2 < θ2, resulting in strong support capacity and high stability. On the other hand, the rotation of the first support rod 22 around the second axis H and the second support rod 32 around the fifth axis K effectively avoids jamming or interference between the first support rod 22 and the first bottom rod 12, and between the second support rod 32 and the second bottom rod 13, during the unfolding or folding process of the bracket 100, which facilitates a smoother switching between the folded and supported states of the bracket 100.
[0084] When the bracket 100 is in the folded state, please refer to Figure 3 The first support rod 22, the second support rod 32, the first base rod 12, and the second base rod 13 are approximately parallel to each other, for example, all extending along the vertical direction X. In this state, the support 100 occupies minimal space in the horizontal direction, which is beneficial for its transportation and storage. In this state, the angles of the first included angle β1, the second included angle β2, the first base angle θ1, and the second base angle θ2 are essentially 0°, all smaller than the angles in the supported state. That is, the angles of the first included angle β1, the second included angle β2, the first base angle θ1, and the second base angle θ2 when the support 100 is in the supported state are all greater than the corresponding angles in the folded state. When the support 100 is in the folded state, both the first support rod 22 and the second support rod 32 are retracted to minimize the space occupied by the support 100 in the folded state.
[0085] When the bracket 100 is in the first intermediate state, please refer to Figure 2 The first included angle β1 is the same as the first base angle θ1, and the second included angle β2 is the same as the second base angle θ2. The first support rod 22 is parallel to the corresponding first base rod 12 and intersects with another first support rod 22. The second support rod 32 is parallel to the corresponding second base rod 13 and intersects with another second support rod 32. In this state, the first support rod 22 is arranged approximately along the extension direction of the first base rod 12, and the second support rod 32 is arranged similarly.
[0086] In some embodiments, please refer to Figure 19 and Figure 20 , Figure 19 This shows a schematic diagram of the structure when the support 100 is in the second intermediate state. Figure 20 This diagram illustrates the flow structure of the support 100 from a folded state to a first intermediate state, then to a second intermediate state, and finally to a supported state. The support 100 also includes a second intermediate state; after sequentially passing through the first and second intermediate states from the folded state, it can unfold to the supported state. When the support 100 is in the second intermediate state, the first included angle β1 is smaller than the first base angle θ1, the second included angle β2 is smaller than the second base angle θ2, the first support rod 22 intersects with the corresponding first base rod 12, and also intersects with another first support rod 22. Please refer to... Figure 21 , Figure 21The dashed line in the diagram indicates the position of the first support assembly when the bracket 100 is in the supported state. The axis of the first support rod 22 and the corresponding axis of the first base rod 12 form a first plane E / E′, where E represents the position of the first plane in the second intermediate state, and E′ represents the position of the first plane in the supported state. The first plane E intersects with the first plane E′ in the supported state, meaning that the spatial position of the first plane E / E′ formed by the axis of the first support rod 22 and the axis of the first base rod 12 is different in the second intermediate state and the supported state.
[0087] Specifically, in the second intermediate state, the angle between the first plane E and the plane formed by the axes of the two first base rods 12 is a first acute angle. In the supported state, the angle between the first plane E′ and the plane formed by the axes of the two first base rods 12 is a second acute angle. The first acute angle and the second acute angle are different. In some embodiments, the first acute angle is smaller than the second acute angle.
[0088] Please see Figure 1 In some embodiments, when the bracket 100 is in the supported state, the first support rod 22 intersects with the corresponding first bottom rod 12 and with another first support rod 22, and the second support rod 32 intersects with the corresponding second bottom rod 13 and with another second support rod 32. That is, in this state, the two first support rods 22 and the two first bottom rods 12 form a support configuration that is narrower at the top and wider at the bottom, and the corresponding two second support rods 32 and the two second bottom rods 13 also form a support configuration that is narrower at the top and wider at the bottom. This makes the center of gravity of the bracket 100 central and lower, and provides a large support area, which is beneficial for maintaining stability during use. In the supported state, the first plane E′ formed by the first support rod 22 and the corresponding first bottom rod 12 is nearly vertical. When the bracket 100 is in the supported state, both the first support rod 22 and the second support rod 32 are extended, thereby increasing the distance between the top rod 4 and the ground.
[0089] In some embodiments, the first support rod 22 and the second support rod 32 are telescopically connected. When the bracket 100 is in the second intermediate state, the first support rod 22 and the second support rod 32 are in a retracted state, and when the bracket 100 is in a supported state, the first support rod 22 and the second support rod 32 are in an extended state. Through the telescopic connection of the first support rod 22 and the second support rod 32, the retracted state in the second intermediate state reduces the space occupied by other rods, and the extended state in the supported state increases the distance between the top rod 4 and the ground, which helps improve the height adaptability of the bracket 100.
[0090] Specifically, taking one side of the first support component 2 as an example, the changes in the bracket 100 during the process of unfolding from the folded state to the supported state are as follows: During the process from the folded state to the first intermediate state, the two first bottom rods 12 rotate around the base 11 in a direction away from each other, and the first support rod 22 rotates synchronously with the first bottom rods 12. In the first intermediate state, the two first support rods 22 are parallel to the corresponding first bottom rods 12. Therefore, the first included angle β1 and the first bottom angle θ1 always remain equal and both gradually increase with the unfolding action. It is worth noting that, due to the existence of error, in this application, when the difference between feature A and feature B is less than three percent of feature A, feature A and feature B can be considered equal.
[0091] During the transition from the first intermediate state to the second intermediate state, the first base angle θ1 remains unchanged, while the first included angle β1 gradually decreases. Specifically, the two first base rods 12 remain fixed, and the first connecting member 21 is pulled outward, causing the two first support rods 22 to rotate around their respective first axes N. During this process, the two first support rods 22 rotate relative to the first base rod 12 around their respective axes (i.e., the direction of the second axis H) and move closer to each other. At the same time, the first rod body 221 rotates relative to the second rod body 222 around the axis of the first support rod 22, thereby avoiding interference between the rods during the unfolding process.
[0092] During the transition from the second intermediate state to the supported state, the first bottom angle θ1 remains unchanged, while the first included angle β1 gradually decreases. Specifically, stretching the first connector 21 causes the first support rod 22 to extend. During this extension, both first support rods 22 rotate outward relative to the corresponding first bottom rod 12 about the axis of the first bottom rod 12 (i.e., the direction of the second axis H) (for example, the first support rod 22 on the left rotates to the left). Furthermore, the first rod body 221 rotates relative to the second rod body 222 about the axis of the first support rod 22, thereby avoiding interference during the unfolding process.
[0093] It is worth noting that the changes in the second included angle β2 and the second bottom angle θ2 on one side of the second support component 3 are similar to the changes in the first included angle β1 and the first bottom angle θ1, and will not be elaborated further in this application.
[0094] It should be noted that during the process of the first support rod 22 switching from the retracted state in the second intermediate state to the extended state in the supporting state, since both first support rods 22 remain connected to the first connector 21, the first support rod 22 needs to rotate relative to the first base rod 12 around the second axis H (i.e., the direction parallel to the axis of the first base rod 12) while extending along its own axial direction. This allows the ends of the two first support rods 22 that are away from the first base rod 12 to move closer to each other after extension to match the reduction of the first included angle β1. At the same time, the first rod body 221 slides and extends relative to the second rod body 222 along the axial direction of the first support rod 22, accompanied by the rotation of the first rod body 221 relative to the second rod body 222 around its own axis, to coordinate the attitude change of the connection positions at both ends of the first support rod 22 during the extension process. Similarly, during the process of the second support rod 32 switching from the retracted state to the extended state, the rotation of the second support rod 32 relative to the second base rod 13 around the fifth axis K and the rotation of the third rod body 321 around its own axis are also similar.
[0095] By coordinating the synchronous rotation of the first support rod 22 around the second axis H during the extension process, and the synchronous rotation of the first rod body 221 around the axis of the first support rod 22 itself, the first support rod 22 and the first bottom rod 12 maintain a coordinated relative posture during the extension process. This effectively avoids interference between the first support rod 22 and the first bottom rod 12 and stress concentration at the connection point, which is beneficial to significantly improving the smoothness of operation and connection reliability of the bracket 100 when it is unfolded from the second intermediate state to the support state.
[0096] By coordinating the synchronous rotation of the first support rod 22 around the second axis H and the synchronous rotation of the first rod body 221 around its own axis, the first included angle β1 and the first base angle θ1 of the bracket 100 can change during the unfolding process. This ensures that the support rods and corresponding base rods maintain continuous movement and coordinated posture in each stage of the unfolding process, effectively avoiding jamming or interference that may occur during unfolding. It also improves the smoothness of switching between the bracket 100 in the folded state, the first intermediate state, the second intermediate state, and the supported state, thereby enhancing the convenience for users to assemble and store the bracket 100.
[0097] It is worth noting that the overall folding process of the bracket 100 switching from the supported state to the folded state is as follows: First, loosen the first fastener 7 and pull the first stud 41 out from the first rotating hole 2111 and the second rotating hole 2121 of the first connector 21. At the same time, loosen the second fastener 10 and pull the second stud 42 out from the third rotating hole 3111 and the fourth rotating hole 3121 of the second connector 31, thereby removing the top rod 4 from between the first connector 21 and the second connector 31. Second, after the two first support rods 22 of the first support assembly 2 lose the lateral constraint of the top rod 4, loosen the locking components 223 on the first support rod 22 and the second support rod 32 respectively, shortening the first support rod 22 and the second support rod 32 to their shortest state, so that the first support rod 22 is folded into its shortest state. The support rod 22 and the second support rod 32 retract to the second intermediate state; in the third step, the first support rod 22 is driven to rotate around the first axis N toward the direction closer to the first bottom rod 12, and the second support rod 32 is driven to rotate around the fourth axis F toward the direction closer to the second bottom rod 13, so that the bracket 100 switches to the first intermediate state; in the fourth step, the user lifts the handle 50 set on the base 11, and under the action of gravity, the first bottom rod 12 and the second bottom rod 13 rotate downward around the base 11 and eventually extend in a roughly vertical direction. At this time, the distance between the end of the first bottom rod 12 away from the base 11 and the end of the second bottom rod 13 away from the base 11 is significantly reduced, and the first support component 2 and the second support component 3 are driven together to a position close to each other, and the bracket 100 enters the folded state as a whole. The unfolding process is the reverse of the above folding process, and will not be described in detail here. Through the above folding process, only the top rod 4 needs to be removed to complete the folding of the main body, without the need to disassemble the metal rods one by one, which is beneficial to significantly improve the storage efficiency of the bracket 100.
[0098] In this embodiment, by setting a detachable connection between one end of the top rod 4 and the first connecting member 21, and the other end of the top rod 4 and the second connecting member 31 (for example, in this embodiment, a threaded detachable connection is made by screwing the first stud 41 to the first fastener 7 and the second stud 42 to the second fastener 10), simply loosening the first fastener 7 or the second fastener 10 and removing the top rod 4 allows the first support assembly 2 and the second support assembly 3 to rotate relative to the base 1 and move closer to each other, thereby completing the folding of the bracket 100. This eliminates the need to disassemble each metal rod individually, simplifying the assembly and storage process of the bracket 100 and improving storage efficiency.
[0099] Example 2 Please see Figure 22 , Figure 23 and Figure 24This embodiment provides another type of bracket 100. The main differences between this embodiment and Embodiment 1 are: the connection method between the top rod 4 and the first connecting member 21 is different; the connection method between the first support base 5 and the first bottom rod 12 is different; and the structure of the first support rod 22 is different. Other structures and functions not specifically described in this embodiment are the same as or similar to those in Embodiment 1, and will not be repeated here.
[0100] Specifically, please refer to Figure 22 and Figure 23 The bracket 100 includes a mounting pin 20, and a mounting shaft 43 is provided at one end of the top rod 4. The mounting shaft 43 is provided with a pin hole 431, which is provided through the radial direction of the mounting shaft 43. After the mounting shaft 43 passes through the first connecting member 21, the mounting pin 20 is removably inserted into the pin hole 431. The ends of the two first support rods 22 away from the first bottom rod 12 are rotatably connected to the first connecting member 21. During assembly, after inserting the mounting shaft 43 into the first connecting member 21, the mounting pin 20 is inserted from the outside into the pin hole 431 to fix the top rod 4 to the first connecting member 21; during disassembly, the mounting pin 20 is pulled out to separate the top rod 4 from the first connecting member 21. This design allows for the assembly and disassembly of the top rod 4 and the first connecting member 21 without the use of tools, which improves assembly and storage efficiency and simplifies the user's steps.
[0101] In some embodiments, please refer to Figure 22 and Figure 23 The first support rod 22 includes a connector 224, which is rotatably connected to the first connecting member 21. Specifically, the connector 224 can rotate about a third axis M relative to the first connecting member 21, so that the two first support rods 22 can move closer to or further away from each other. The third axis M can be parallel to the axis of the top rod 4 or not parallel to the axis of the top rod 4. In this embodiment, the third axis M is inclined relative to the axis of the top rod 4. The connector 224 is provided with a rotating shaft 2241. The end of the second rod 222 away from the first rod 221 is provided with a rotating groove 2212. The rotating shaft 2241 is inserted into the rotating groove 2212, so that the first rod 221 can rotate about the axis of the rotating shaft 2241 relative to the first bottom rod 12. The axis of the rotating shaft 2241 can coincide with the axis of the first support rod 22, so that the first support rod 22 can rotate about its own axis during the deployment of the bracket 100, thereby avoiding interference during the deployment process.
[0102] In some embodiments, the cross-sections of the first rod 221 and the second rod 222 can be circular, square, triangular, etc. In this embodiment, the cross-sectional shapes of the first rod 221 and the second rod 222 are rectangular. Since the first support rod 22 can rotate about the axis of the rotation shaft 2241, the first rod 221 and the second rod 222 do not need to rotate relative to each other. Therefore, the cross-sectional shapes of the first rod 221 and the second rod 222 are not limited to circular.
[0103] It is worth noting that, since the second rod 222 can rotate relative to the first bottom rod 12 about the axis of the rotation shaft 2241, there is no need for relative rotation between the first rod 221 and the second rod 222. It is only necessary for the first rod 221 to slide relative to the second rod 222 along the axial direction of the first support rod 22 to achieve retraction or extension.
[0104] In some embodiments, please refer to Figure 23 The bracket 100 also includes a limiting screw 60. The first connecting member 21 is provided with a threaded groove 213. The peripheral wall of the mounting shaft 43 is provided with an annular groove 432, which extends circumferentially around the mounting shaft 43. When the push rod 4 is connected to the first connecting member 21, the limiting screw 60 is screwed into the threaded groove 213, and the limiting screw 60 is at least partially received in the annular groove 432 to restrict the movement of the mounting shaft 43 along the axial direction of the push rod 4. Through the cooperation of the limiting screw 60 and the annular groove 432, after the end of the limiting screw 60 is embedded in the annular groove 432, the displacement of the mounting shaft 43 can be restricted in the axial direction. The limiting screw 60 and the mounting pin 20 work together to improve the stability of the connection between the push rod 4 and the first connecting member 21 and reduce the risk of the push rod 4 becoming loose during use.
[0105] In some embodiments, please refer to Figure 22 and Figure 24 The bracket 100 includes a support foot pad 30 and a rotating pin 40. The support foot pad 30 is located at the end of the first base rod 12 away from the seat 11, for contacting the ground and providing stable support. The support foot pad 30 is provided with a first rotating lug 301, and the first support seat 5 is provided with a second rotating lug 53. Both the first rotating lug 301 and the second rotating lug 53 are generally ear-shaped structures with through holes. The rotating pin 40 is generally slender and columnar, and the rotating pin 40 passes sequentially through the first rotating lug 301 and the second rotating lug 53 along the axial direction of the first base rod 12. The second rotating lug 53 can rotate around the rotating pin 40. The support foot pad 30 provides stable contact with the ground, the second rotating lug 53 can rotate around the rotating pin 40, and the first support seat 5 can rotate relative to the support foot pad 30 and the first base rod 12. During the folding process, the first support rod 22 drives the first support seat 5 to rotate around the rotating pin 40, which helps to improve the smoothness of the rotation of the first support rod 22 relative to the first bottom rod 12.
[0106] This application also provides an embodiment of a swing 1000; please refer to [link / reference]. Figure 25 and Figure 26 The swing 1000 includes a seat 300, at least two mounting mechanisms 200, and the aforementioned bracket 100. Both mounting mechanisms 200 are connected to the top rod 4 of the bracket 100. One mounting mechanism 200 is connected to one end of the seat 300, and the other mounting mechanism 200 is connected to the other end of the seat 300.
[0107] In some embodiments, the mounting mechanism 200 is provided with a plurality of spaced-apart mounting portions 201, which are spaced apart along the length of the mounting mechanism 200. The seat 300 includes a body 301 and at least two hanging members 302, wherein one hanging member 302 is connected to the body 301 and detachably connected to the mounting portion 201 of one of the mounting mechanisms 200; the other hanging member 302 is connected to the body 301 and detachably connected to the mounting portion 201 of the other mounting mechanism 200. The body 301 is at least partially located between the two hanging members 302. In this embodiment, by providing multiple spaced-apart mounting parts 201 along the length of the mounting mechanism 200, the user can selectively connect the hanging part 302 to different mounting parts 201 as needed, thereby adjusting the suspension height of the seat 300 relative to the top rod 4. This allows the swing 1000 to adapt to the needs of users of different heights or different usage scenarios, significantly improving the flexibility and human-machine adaptability of the swing 1000.
[0108] In some embodiments, the suspension member 302 includes a suspension rope 3021 and a hook 3022. One end of the suspension rope 3021 is connected to the body 301, and the other end of the suspension rope 3021 is connected to the hook 3022. The hook 3022 is detachably connected to the mounting part 201. When the user needs to adjust the suspension height of the seat 300, the user only needs to remove the hook 3022 from the current mounting part 201 and hook it to another mounting part 201 to complete the height adjustment without the need for additional tools, which improves the convenience and efficiency of the seat 300 height adjustment.
[0109] In some embodiments, please continue reading Figure 25 and Figure 26The support frame 100 includes at least two spaced-apart hangers 70, which are spaced apart on the top rod 4 along its axial direction. A mounting mechanism 200 is connected to one hanger 70. By providing two spaced-apart hangers 70 along the axial direction of the top rod 4 to support the two mounting mechanisms 200 respectively, the arbitrary displacement of the two mounting mechanisms 200 on the top rod 4 along its axial direction can be restricted. This reduces the risk of tilting or instability of the seat 300 due to the sliding of the mounting mechanisms 200 on the top rod 4, and helps to improve the stability and safety of the swing 1000 during use.
[0110] In some embodiments, please refer to Figure 26 and Figure 27 The hanger 70 includes a mounting body 701 and a bearing 702. The bearing 702 is disposed on the mounting body 701, and the hanging mechanism 200 is wound around the bearing 702. During the user's use of the swing 1000, there is relative movement between the hanging mechanism 200 and the hanger 70. By setting the bearing 702, the relative movement between the hanging mechanism 200 and the hanger 70 can be replaced by direct sliding friction through the rolling friction inside the bearing 702. This significantly reduces the frictional force between the hanging mechanism 200 and the hanger 70, reduces the wear of the hanging mechanism 200 caused by repeated friction over a long period of time, and improves the smoothness of the swing 1000's swing, thus enhancing the user experience.
[0111] In some embodiments, the mounting body 701 includes a central portion 7011 and two side portions 7012. One side portion 7012 is connected to one end of the central portion 7011, and the other side portion 7012 is connected to the other end of the central portion 7011. A bearing 702 is connected to at least one side portion 7012. The central portion 7011, the bearing 702, and the two side portions 7012 together form a mounting hole 703. The mounting mechanism 200 passes through the mounting hole 703 and is connected to the seat 300. Because the mounting hole 703, formed by the central portion 7011, the bearing 702, and the two side portions 7012, allows the mounting mechanism 200 to be inserted through the mounting hole 703 during installation, thus simplifying the assembly process between the mounting mechanism 200 and the hanger 70 and improving assembly efficiency.
[0112] In some embodiments, the mounting mechanism 200 includes a sling 202 wound around the bearing 702. The mounting part 201 includes mounting holes 2012 penetrating the sling 202, which are used for attaching the suspension rope 3021. Specifically, the sling 202 has multiple mounting holes 2012 spaced apart along its length, and all mounting holes 2012 are through holes. The user can complete the detachable connection between the suspension rope 3021 and the mounting part 201 by hooking the hook 3022 onto the selected mounting hole 2012, which is convenient to operate. By using multiple mounting holes 2012 spaced apart on the sling 202 as the mounting part 201, the structure is simple, the processing requirements are low, and the mounting holes 2012 themselves are not easily damaged by long-term repeated use, which helps to improve the durability of the swing 1000 while ensuring the adjustment function.
[0113] In other embodiments, please refer to Figure 28 The mounting mechanism 200 includes a sling 202, which includes a first sling body 2021 and a second sling body 2022. Along the length of the first sling body 2021, a portion of the first sling body 2021 is sewn to the second sling body 2022, while another portion is separated from the second sling body 2022, so that the separated portion of the first sling body 2021 and the second sling body 2022 forms the mounting portion 201. That is, the sewn area between the first sling body 2021 and the second sling body 2022 divides the entire sling 202 along its length into multiple spaced-apart separation areas. In each separation area, an annular space is formed between the first sling body 2021 and the second sling body 2022, which can be hooked by a hook 3022. The multiple annular spaces constitute multiple mounting portions 201. With this configuration, multiple spaced annular mounting portions 201 are formed between the first belt body 2021 and the second belt body 2022. The hook 3022 can be selectively mounted to different mounting portions 201, which facilitates the adjustment of the height of the seat 300. The overall structure is stable, the processing technology is simple, and it is not easily damaged due to long-term use. This is conducive to balancing the adjustability and durability of the swing 1000.
[0114] In some embodiments, please refer to Figure 26The mounting section 201 may also include a lifting ring 2011, which is located at the end of the sling 202 away from the hanger 70. The lifting ring 2011 is used for attaching the lifting rope 3021. That is, a lifting ring 2011 is provided at the end of the sling 202 as the mounting section 201, and the hook 3022 can be attached to the lifting ring 2011, forming a stable connection between the lifting rope 3021 and the sling 202. With the addition of the lifting ring 2011, the position and shape of the mounting section 201 are clearly defined, facilitating the quick attachment and detachment of the hook 3022, and further improving the assembly efficiency and ease of use of the swing 1000.
