Description

Technical Field

[0001] This invention relates to the field of support technology, and more specifically to a support rod. Background Technology

[0002] Existing rotating bracket-type elastic support structures mostly use a single spring as an elastic reset or balancing component to assist in balancing. In traditional support structures, the spring arrangement, such as rigidly fixing the two ends of the spring, limits the spring deformation to the structure and cannot adaptively adjust with the rotation angle of the bracket. This can easily cause the bracket to jam, experience uneven force, or even fail elastically. During rotation, the elastic force fluctuates greatly, making it difficult to maintain a stable state. The spring is prone to swaying and shifting, and cannot form a continuous and reliable force balance. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, this invention provides a support rod with a simple structure, good balance performance, and the ability to achieve stable suspension of the support component.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] This invention discloses a support rod, comprising:

[0006] Fixed arm;

[0007] The support arm is rotatably connected to the fixed arm;

[0008] The connecting seat has one end rotatably connected to the support arm, and the other end is configured to install the component to be supported.

[0009] A limiting seat is disposed inside the support arm and has a through hole arranged along the first direction;

[0010] A first elastic component is disposed within the support arm, including a first connecting rod having a first end and a second end, and a first elastic member disposed between the first end of the first connecting rod and the limiting seat. The first connecting rod passes through a through hole in the limiting seat, and the first elastic member is configured to apply a first biasing force to the first end of the first connecting rod.

[0011] The second elastic component is disposed within the support arm and includes a second elastic element. The two ends of the second elastic element are respectively connected to the second end of the first connecting rod and the fixed arm. The second elastic element is configured to apply a second biasing force to the first connecting rod.

[0012] The dual elastic components in the above technical solution, through the coordinated arrangement of the first elastic element and the second elastic element applying different bias forces to the first connecting rod, can form a bidirectional force balance. This allows the first and second elastic elements to adaptively change their deformation as the supported component rotates, thereby adaptively adjusting their bias forces to achieve mutual compensation of elastic forces. This adaptively matches the changing gravitational torque at different angles and heights, enabling the supported component to maintain dynamic balance during rotation and achieve stable hovering. Compared to structures that hover using a single spring, the support rod provided in this application has better balance and stability.

[0013] Furthermore, the first elastic element is sleeved on the first connecting rod, and the first elastic element is configured to apply a biasing force away from the second elastic element to the first end of the first connecting rod, and the second elastic element is configured to apply a biasing force away from the first elastic element to the second end of the first connecting rod.

[0014] Furthermore, one end of the first elastic member is connected to the first end of the first connecting rod, and the other end is configured to apply a biasing force close to the second elastic member to the first end of the first connecting rod. The second elastic member is configured to apply a biasing force close to the first elastic member to the second end of the first connecting rod.

[0015] The above technical solution uses one elastic element to pull the first link, and the other elastic element forms a bidirectional force balance with it. When the component to be supported rotates, the first elastic element adjusts the bias force applied to the first link through its own compression or elongation. At the same time, the second elastic element compensates accordingly based on the displacement of the first link. This structural arrangement can improve the dynamic balance stability of the support rod and enhance the adaptability of the support rod in different usage scenarios.

[0016] Furthermore, the first end of the first connecting rod is provided with a first stop portion, one end of the first elastic member is connected to the first stop portion, and the other end is connected to the limiting seat. The connection arrangement of the first elastic member with the first stop portion and the second stop portion can prevent the first elastic member from excessive displacement during the force process and reduce the risk of the first elastic member loosening due to external vibration or impact.

[0017] Furthermore, the second end of the first connecting rod is provided with a second stop portion. The second stop portion is located on the side of the limiting seat opposite to the first elastic member and is connected to the second elastic member. The diameter of the second stop portion is larger than the diameter of the through hole. The second stop portion can limit the movement range of the first connecting rod and prevent it from detaching from the constraint of the limiting seat during the application of force.

[0018] Furthermore, the second elastic component also includes a first connecting shaft, a second connecting shaft, and a second connecting rod connected between the first and second connecting shafts. The first connecting shaft is connected to the fixed arm, and one end of the second elastic component is connected to the second end of the first connecting rod, while the other end is connected to the second connecting shaft. During the application of force, the second connecting rod can achieve fine-tuning of its angle through the cooperation of the first and second connecting shafts. When the angle of the component to be supported changes, the second elastic component can adaptively compensate, thereby further improving the overall stability and adaptability of the support rod.

[0019] Furthermore, the support arm is symmetrically provided with limiting slots on both sides, and both ends of the first connecting shaft pass through the limiting slots and can move along the limiting slots. The limiting slots can limit the range of movement of the first connecting shaft and guide the first connecting shaft to ensure the stability of the second elastic component during rotation.

[0020] Furthermore, it also includes a protective cover, the inner side of which is provided with a buckle, and the support arm is provided with a locking hole corresponding to the buckle. The protective cover and the support arm are fastened together by the buckle and the locking hole.

[0021] Furthermore, the limiting seat is provided with a first through hole and a second through hole arranged along the second direction, and the two sides of the support arm are provided with connecting holes corresponding to the first through hole and the second through hole. The limiting seat is connected to the support arm by a pin passing through the first through hole and the connecting hole, the second through hole and the connecting hole.

[0022] Furthermore, the support arm includes a first support arm and a second support arm disposed below the first support arm. The two ends of the first support arm are connected to the connecting seat and the fixed arm respectively via a first pivot and a second pivot. The two ends of the second support arm are connected to the connecting seat and the fixed arm respectively via a third pivot and a fourth pivot. The cooperative connection of the first and second support arms allows the entire support arm to be detachable, facilitating rapid assembly of the support rod as a whole.

[0023] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art:

[0024] The support rod of this application is equipped with a dual elastic component. Through the coordinated arrangement of the first elastic element and the second elastic element applying different bias forces to the first connecting rod, a bidirectional force balance can be formed. This allows the first and second elastic elements to adaptively change their deformation as the supported component rotates, thereby adaptively adjusting their bias forces to achieve mutual compensation of elastic forces. This adaptively matches the changing gravitational torque at different angles and heights, enabling the supported component to maintain dynamic balance during rotation and achieve stable hovering. Compared with structures that hover using a single spring, the support rod provided in this application has better balance and stability.

[0042] Example 1: Refer to Figures 1-8 This embodiment provides a support rod, including a fixed arm 1, a support arm 2 rotatably connected to the fixed arm 1, a connecting seat 3 rotatably connected to the support arm 2 at one end and configured at the other end to mount the component to be supported, a limiting seat 4, a first elastic component, and a second elastic component disposed within the support arm 2. The limiting seat 4 has a through hole 41 arranged along a first direction. The first elastic component includes a first connecting rod 51 having a first end and a second end, and a first elastic element 52 disposed between the first end of the first connecting rod 51 and the limiting seat 4. The second end of the first connecting rod 51 passes through the through hole 41, and the first elastic element 52 is configured to apply a first biasing force to the first end of the first connecting rod 51. The second elastic component includes a second elastic element 61, with both ends of the second elastic element 61 connected to the second end of the first connecting rod 51 and the fixed arm 1, respectively. The second elastic element 61 is configured to apply a second biasing force to the first connecting rod 51.

[0043] like Figures 5-8 As shown, the support arm 2 includes a first support arm 21 and a second support arm 22 disposed below the first support arm 21. The first support arm 21 has a first end and a second end. The first end of the first support arm 21 is rotatably connected to the connecting seat 3, and the second end is rotatably connected to the fixed arm 1. Specifically, the first end and the second end of the first support arm 21 are respectively provided with a first pivot hole and a second pivot hole. The connecting seat 3 and the fixed arm 1 are respectively provided with shaft holes corresponding to the first pivot hole and the second pivot hole. A first pivot shaft 31 passes through the first pivot hole and the shaft hole on the connecting seat 3, and a second pivot shaft 11 passes through the second pivot hole and the shaft hole on the fixed arm 1. The second support arm 22 has a first end and a second end. The first end of the second support arm 22 is rotatably connected to the connecting seat 3, and the second end is rotatably connected to the fixed arm 1. Specifically, the first end and the second end of the second support arm 22 are respectively provided with a third pivot hole located below the first pivot hole and a fourth pivot hole located below the second pivot hole. The connecting seat 3 and the fixed arm 1 are respectively provided with shaft holes corresponding to the third pivot hole and the fourth pivot hole. The third pivot hole and the shaft hole on the connecting seat 3 are provided with a third pivot 32, and the fourth pivot hole and the shaft hole on the fixed arm 1 are provided with a fourth pivot 12.

[0044] The limiting seat 4 is located within the second support arm 22 and is used to limit the stroke of the first elastic component and the second elastic component. Figure 8 As shown, the limiting seat 4 is provided with a first through hole 42 and a second through hole 43 arranged along the second direction, and the first through hole 42 and the second through hole 43 are located on both sides of the through hole 41. The two opposite sides of the second support arm 22 are respectively provided with connecting holes 221 corresponding to the size and shape of the first through hole 42 and the second through hole 43. When the limiting seat 4 is installed in the second support arm 2, the first through hole 42 is connected to the connecting hole on one side of the second support arm 2, and the second through hole 43 and the connecting hole on the other side of the second support arm 2 are all provided with pins 222, thereby fixing the limiting seat 4 and the second support arm 22 together.

[0045] like Figures 3-7 As shown, the first end of the first connecting rod 51 is provided with a first stop part 511, the first stop part 511 is a free end, one end of the first elastic member 52 is connected to the first stop part 511, and the other end is connected to the limiting seat 4.

[0046] In this embodiment, the first elastic element 52 is sleeved on the first connecting rod 51. The first elastic element 52 is configured to apply a biasing force to the first stop portion 511, causing it to move away from the second elastic element 61. The second elastic element 61 is configured to apply a biasing force to the second end of the first connecting rod 51, causing it to move away from the first elastic element 52. When the component to be supported rotates, the second elastic element 61 applies a pulling force to the second end of the first connecting rod 51, causing the first connecting rod 51 to move towards the second elastic element 61. At the same time, the first elastic element 52 abuts against the limiting seat 4 and the first stop portion 511, causing the first stop portion 511 to move away from the second elastic element 61. The biasing forces of the second elastic element 61 and the first elastic element 52 compensate for each other, so that the entire support rod maintains dynamic balance during movement, thereby improving the stability of the support rod.

[0047] The second end of the first link 51 is provided with a second stop 512. The second stop 512 is located on the side of the limiting seat 4 away from the first elastic member 52 and is connected to the second elastic member 61. The diameter of the second stop 512 is larger than the diameter of the through hole 41 to limit the movement stroke of the first link 51.

[0048] The second elastic component also includes a first connecting shaft 62, a second connecting shaft 63, and a second connecting rod 64 connected between the first connecting shaft 62 and the second connecting shaft 63. The first connecting shaft 62 is connected to the fixed arm 1. One end of the second elastic member 61 is connected to the second stop 512, and the other end is connected to the second connecting shaft 63. The second elastic member 61 and the second connecting shaft 63 can move relative to each other.

[0049] In this embodiment, the second elastic member 61 is inclined, with its first end at a lower height than its second end. This allows it to generate an upward lifting torque around the fixed arm 1 within the four-bar linkage formed by the second elastic member 61 above, below, left, and right. The first end of the second elastic member 61 is connected to the second stop portion 512, and the second end is connected to the second connecting shaft 63.

[0050] The first connecting shaft 62 can be connected at any position between the second rotating shaft 11 and the fourth rotating shaft 12, ensuring that the connection position does not affect the complementary function of the tension and compression positions of the dual elastic components during adjustment. Optionally, the first connecting shaft 62 is connected to the second rotating shaft 11. When the second connecting shaft 63 and the second connecting rod 64 move relative to each other, the second connecting rod 64 can move within the internal space of the second elastic element 61, thus making the overall structure more compact. Optionally, the connection between the first connecting shaft 62 and the second rotating shaft 11 adopts a rotatable structure, allowing the second connecting rod 64 to rotate within a certain range to cope with external forces in different directions.

[0051] Specifically, this embodiment provides usage diagrams of the first elastic element 52 and the second elastic element 61 under different force directions. For example... Figure 9 As shown, when the second elastic member 61 applies a tensile force, the first elastic member 52 provides a horizontal resisting force against the first stop portion 511. Figure 10 As shown, when the second elastic member 61 applies a tensile force, the first elastic member 52 provides an abutment force against the first stop portion 511 along the first inclined direction. Figure 11 As shown, when the second elastic member 61 applies a pulling force, the first elastic member 52 provides a resisting force to the first stop portion 511 along the second inclined direction, and the first stop portion 511 is in a suspended state.

[0052] It should be noted that in this embodiment, the first direction is the setting direction of the first elastic member 52 and the second elastic member 61, and the second direction is perpendicular to the first direction. The above usage state is only a partial usage example of this embodiment and does not limit the specific usage state.

[0053] The first support arm 21 has symmetrical limiting strip holes 211 on both sides. The height of the limiting strip holes 211 gradually increases from the end near the first rotating shaft 31 to the end near the second rotating shaft 11. The two ends of the first connecting shaft 62 pass through the limiting strip holes 211 and can move along the limiting strip holes 211.

[0054] A protective cover 7 is provided on the outside of the limiting strip hole 211, and a buckle 71 is provided on the inside of the protective cover 7. A buckle hole 212 corresponding to the buckle 71 is provided on the first support arm 21. The protective cover 7 and the first support arm 21 are fastened together by the buckle 71 and the buckle hole 212.

[0055] Example 2: This example provides a support rod. The structure of this support rod is similar to that in Example 1, except that one end of the first elastic element 52 is connected to the first stop 511, and the other end is connected to the limiting seat 4. The first elastic element 52 is configured to apply a pulling force to the first stop 511, causing it to move closer to the second elastic element 61. The second elastic element 61 is configured to apply an abutting force to the second stop 512, causing it to move closer to the first elastic element 52. When the supported component rotates, the second elastic element 61 applies a biasing force to the second end of the first connecting rod 51, causing the first connecting rod 51 to move away from the second elastic element 61. Simultaneously, the first elastic element 52 applies a pulling force to the limiting seat 4 and the first stop 511, causing the first stop 511 to move closer to the second elastic element 61. The biasing forces of the second elastic element 61 and the first elastic element 52 compensate for each other, maintaining dynamic balance of the support rod during movement and thus improving its stability.

[0056] In this embodiment, the first elastic member 52 is inclined, and the height of one end of the first stop portion 511 is higher than the height of the other end. The second elastic member 61 is horizontally arranged. The first connecting shaft 62 is connected to the fourth rotating shaft 12. The limiting strip hole 211 on the first support arm 21 is horizontally arranged.

[0057] It should be noted that in the above embodiments, the first elastic element 52 and the second elastic element 61 can be springs, disc springs, rubber or other structures with elastic functions, and this application does not make specific limitations here.

[0058] The support rod in this embodiment can form a bidirectional force balance through the first elastic element 52 and the second elastic element 61. When the supported component rotates, it can adaptively change its deformation, thereby adaptively adjusting the bias force of the two elements to achieve mutual compensation of elastic forces. It adaptively matches the changing gravitational torque at different angles and heights, so that the supported component maintains dynamic balance during rotation and achieves stable hovering. It has strong versatility and can install displays, lighting fixtures, signs, sensing devices or other functional accessories according to actual needs. It has a wide range of applications and can be widely used in school classrooms, office areas, industrial production plants, commercial places, public service spaces and various indoor and outdoor scenarios to meet the equipment installation, support and layout needs in different environments.

The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this invention. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this invention. Therefore, the content of this specification should not be construed as a limitation of this invention.
