Description

Technical Field

[0001] This utility model relates to the field of laptop stand technology, and in particular to a dual-axis linkage liftable electric stand. Background Technology

[0002] A laptop stand is an accessory specifically designed for laptops. It is usually made of materials such as metal, plastic, or wood. Through a specific structural design (such as adjustable height and angle support arms or support panels), it supports the laptop at a certain position above the desktop to achieve functions such as raising the screen, improving ergonomic posture (such as relieving pressure on the cervical and lumbar spine), and increasing the heat dissipation space under the computer. It is widely used in office, study, and entertainment scenarios. Some stands also have features such as folding for portability and compatibility with multiple devices.

[0003] Currently, laptop stands are mostly single-axis or dual-axis linkage designs. Dual-axis linkage stands connect different support components through two rotatable axes (such as hinges or pivots), using the rigid structure of the axes to distribute the weight of the laptop, while the damping design of the axes (such as springs, friction plates, or gear meshing) achieves positioning after angle adjustment. However, with long-term use, due to continuous angle adjustments, the damping components of the axes will wear and age (such as friction plate wear and reduced spring force), resulting in the stand becoming loose and affecting the use of the laptop. Moreover, a typical dual-axis linkage stand cannot support a heavy laptop. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a dual-axis linkage liftable electric support.

[0005] This utility model is achieved using the following technical solution: a dual-axis linkage liftable electric support, comprising a base, a first support plate rotatably mounted on the top of the base, a second support plate rotatably mounted on one side of the top of the first support plate, a lifting assembly for controlling the lifting and lowering of the support mounted on both the base and the first support plate, and a fixing assembly for fixing the position of the first and second support plates after lifting and lowering mounted on both the base and the first support plate, the lifting assembly comprising an electric telescopic rod disposed on the top of the base, a rotating shaft fixedly mounted at both ends of the electric telescopic rod, and a connecting plate rotatably mounted at both ends of the two rotating shafts, one side of each connecting plate being fixedly mounted to the bottom side of an adjacent base or first support plate, a sliding groove being provided on the side of the two connecting plates near the rotating shaft on the bottom side of the first support plate, both ends of the rotating shaft on the bottom side of the first support plate extending into the interior of the adjacent sliding groove, the sliding groove being T-shaped, and a control button for controlling the adjacent electric telescopic rod being mounted on one side of both the base and the first support plate.

[0006] By utilizing the telescopic characteristics of the electric telescopic rod and the rotating connection of the rotating shaft and connecting plate, the automatic lifting and lowering control of the first and second support plates can be achieved. The operation is convenient, and the electric telescopic rods at different positions can be controlled separately through the control buttons to meet different lifting requirements.

[0007] As a further improvement to the above solution, the fixing component includes a limiting plate fixedly installed on both sides of the base. Both limiting plates are semi-circular in shape, and multiple fixing grooves arranged in a ring array are opened on the cylindrical surface of both limiting plates. A fixing plate is provided on the bottom side of the first support plate, and both ends of the fixing plate extend into the fixing groove of the adjacent limiting plate.

[0008] With the above technical solution, the two ends of the fixing plate extend into the fixing groove of the limiting plate, which can initially fix the position of the first support plate and the second fixing plate, prevent them from shaking during use, and ensure the stability of the bracket.

[0009] As a further improvement to the above solution, each of the fixing slots is inclined, and both ends of the fixing plate are provided with slots that are adapted to the fixing slots. The fixing plate is engaged with the two limiting plates through the fixing slots.

[0010] Through the above technical solution, the inclined fixing groove is matched with the slots at both ends of the fixing plate, which can enhance the locking force between the fixing plate and the limiting plate, further improve the stability of the first support plate after it is fixed, and the inclined structure also facilitates smooth locking and separation during adjustment.

[0011] As a further improvement to the above solution, each of the two fixed plates is fitted with a limiting plate at both ends. Each limiting plate is concave and fixedly installed with the bottom side of the adjacent first support plate or the bottom side of the second support plate. One side of each of the two fixed plates is in contact with the inner wall of the adjacent limiting plate, and both fixed plates are in sliding cooperation with the adjacent limiting plate.

[0012] Through the above technical solution, the limiting plate plays a guiding and limiting role for the fixed plate, so that the fixed plate can only slide within a limited range, ensuring accurate matching between the fixed plate and the limiting plate. At the same time, the sliding matching method also facilitates the position adjustment of the fixed plate.

[0013] As a further improvement to the above solution, each of the limiting plates is provided with a limiting post at one end, and one end of each limiting post extends through the adjacent limiting plate into its interior and is fixedly installed with the adjacent fixing plate. Each limiting post is fitted with a spring, and the two ends of each spring abut against the adjacent fixing plate and the limiting plate, respectively.

[0014] Through the above technical solution, the elastic force of the spring can generate a thrust on the fixed plate, so that the fixed plate always tends to move towards the limiting plate, ensuring a tight engagement between the fixed plate and the limiting plate and improving the reliability of the fixation. The limiting post plays a limiting role for the spring, preventing the spring from deviating during the extension and contraction process.

[0015] As a further improvement to the above solution, hook plates in an "L" shape are rotatably installed at both ends of the two fixed plates, and fixed posts are fixedly installed on both sides of the first support plate and both sides of the second support plate. A limiting groove adapted to the fixed post is opened on one side of each hook plate.

[0016] With the above technical solution, when the fixed plate needs to be moved, the fixed plate is slid upward and then the hook plate is rotated so that the limiting groove on the hook plate is engaged with the fixed column, thereby releasing the restriction of the fixed plate on the limiting plate and allowing the first support plate and the second support plate to rotate.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention achieves both electric lifting and stable fixing of the bracket by setting up a lifting component and a fixing component. The lifting component is driven by an electric telescopic rod, which is easy to operate and can quickly and accurately adjust the height of the bracket. The fixing component, through a multi-locking structure, ensures the stability of the bracket after adjustment, meets the usage needs of different users in different scenarios, and improves the user experience.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0028] Please combine Figures 1-6 This embodiment of a dual-axis linkage liftable electric support includes a base 1, a first support plate 2 rotatably mounted on the top of the base 1, a second support plate 3 rotatably mounted on one side of the top of the first support plate 2, a lifting assembly for controlling the lifting and lowering of the support on both the base 1 and the first support plate 2, and a fixing assembly for fixing the position of the first support plate 2 and the second support plate 3 after lifting and lowering on both the base 1 and the first support plate 2.

[0029] The lifting assembly includes an electric telescopic rod 401 mounted on the top of the base 1. Rotating shafts 402 are fixedly installed at both ends of the electric telescopic rod 401. Connecting plates 403 are rotatably mounted at both ends of the two rotating shafts 402. One side of each connecting plate 403 is fixedly installed to the bottom side of the adjacent base 1 or the first support plate 2. Sliding grooves are provided on the side of the two connecting plates 403 located on the bottom side of the first support plate 2 near the rotating shafts 402. Both ends of the rotating shafts 402 located on the bottom side of the first support plate 2 extend into the interior of the adjacent sliding grooves. The sliding grooves are T-shaped. Control buttons 404 for controlling the adjacent electric telescopic rods 401 are installed on one side of both the base 1 and the first support plate 2.

[0030] By utilizing the telescopic characteristics of the electric telescopic rod 401, and in conjunction with the rotational connection of the rotating shaft 402 and the connecting plate 403, automated lifting control of the first support plate 2 and the second support plate 3 can be achieved. The operation is convenient, and the electric telescopic rod 401 at different positions can be controlled separately through the control button 404 to meet different lifting needs.

[0031] The fixing assembly includes limiting plates 501 fixedly installed on both sides of the base 1. Both limiting plates 501 are semi-circular in shape, and multiple fixing grooves arranged in a ring array are opened on the cylindrical surface of both limiting plates 501. A fixing plate 502 is provided on the bottom side of the first support plate 2. Both ends of the fixing plate 502 extend into the fixing groove of the adjacent limiting plate 501. The two ends of the fixing plate 502 extending into the fixing groove of the limiting plate 501 can initially fix the position of the first support plate 2 and the second support plate 3, preventing them from shaking during use and ensuring the stability of the bracket. Each fixing groove is inclined. Both ends of the fixing plate 502 are provided with slots that are adapted to the fixing groove. The fixing plate 502 engages with the two limiting plates 501 through the fixing groove. The inclined fixing grooves are adapted to the slots at both ends of the fixing plate 502, which can enhance the engagement force between the fixing plate 502 and the limiting plate 501, further improving the stability of the first support plate 2 and the second support plate 3 after fixing. At the same time, the inclined structure also facilitates smooth engagement and disengagement during adjustment.

[0032] Both ends of the two fixed plates 502 are fitted with limiting plates 6, each limiting plate 6 being concave. Each limiting plate 6 is fixedly installed to the bottom side of the adjacent first support plate 2 or the bottom side of the second support plate 3. One side of each of the two fixed plates 502 is in contact with the inner wall of the adjacent limiting plate 6. Both fixed plates 502 are in sliding engagement with the adjacent limiting plate 6. The limiting plates 6 guide and limit the fixed plates 502, ensuring that the fixed plates 502 can only slide within a limited range. This guarantees accurate engagement between the fixed plates 502 and the limiting plates 501. The sliding engagement also facilitates position adjustment of the fixed plates 502. Each limiting plate 6... Each end is provided with a limiting post 7. One end of each limiting post 7 extends through the adjacent limiting plate 6 and is fixedly installed with the adjacent fixing plate 502. Each limiting post 7 is fitted with a spring 8. The two ends of each spring 8 abut against the adjacent fixing plate 502 and the limiting plate 6 respectively. The elastic force of the spring 8 can generate a pushing force on the fixing plate 502, so that the fixing plate 502 always has a tendency to move towards the limiting plate 501, ensuring a tight engagement between the fixing plate 502 and the limiting plate 501, and improving the reliability of the fixation. The limiting post 7 plays a limiting role for the spring 8, preventing the spring 8 from shifting during the extension and retraction process.

[0033] Both ends of the two fixed plates 502 are rotatably mounted with hook plates 9 arranged in an "L" shape. The two sides of the first support plate 2 and the two sides of the second support plate 3 are fixedly mounted with fixing posts 10. Each hook plate 9 has a limiting groove on one side that matches the fixing post 10. When the fixed plate 502 needs to be moved, the fixed plate 502 is slid upward and then the hook plate 9 is rotated so that the limiting groove on the hook plate 9 fits and hooks with the fixing post 10, thereby releasing the restriction of the fixed plate 502 on the limiting plate 501, so that the first support plate 2 and the second support plate 3 can be rotated.

[0034] The implementation principle of a dual-axis linkage liftable electric support in this embodiment is as follows: Pressing the control button 404 on the base 1 and the first support plate 2 controls the extension and retraction of the electric telescopic rod 401 at the top of the base 1 and the top of the first support plate 2. When the electric telescopic rod 401 extends and retracts, the rotating shafts 402 at both ends move and rotate inside the sliding groove of the connecting plate 403. Since the connecting plates 403 at both ends of the rotating shaft 402 are fixedly connected to the base 1 and the first support plate 2 respectively, they will rotate as the rotating shaft 402 moves. The rotational force will drive the first support plate 2 to rotate around the rotating connection point with the base 1, thereby adjusting the height of the first support plate 2. The second support plate 3 will also rotate with the first support plate 2 for the same reason.

[0035] During the rotation of the first support plate 2 and the second support plate 3, the spring 8 will continuously push the fixed plate 502, and the fixed plate 502 will always remain in contact with the limiting plate 501. The fixed plate 502 will move with the rotation of the first support plate 2 and the second support plate 3, so that the slot of the fixed plate 502 will always be in contact with the fixed groove of the limiting plate 501. Since the fixed groove is inclined, the fixed plate 502 can only move up and down in the inclined direction. Reverse movement will be blocked by the vertical edge of the fixed groove. Thus, the fixed plate 502 and the limiting plate 501 form a ratchet and a locking block cooperation.

[0036] After the positions of the first support plate 2 and the second support plate 3 are adjusted, press the control button 404 again to retract the electric telescopic rod 401, so that the slot of the fixed plate 502 is tightly against the fixed slot of the limiting plate 501, and the limiting plate 501 provides support for the fixed plate 502. At this time, stop the control button 404. Since the rotating shaft 402 slides inside the sliding groove of the connecting plate 403, it provides distance for the retraction of the electric telescopic rod 401, avoiding damage caused by the electric telescopic rod 401 failing to retract properly. After the electric telescopic rod 401 retracts, the weight of the first support plate 2 and the second support plate 3 will press on the fixed plate 502 and the limiting plate 501, so that the main support of the first support plate 2 and the second support plate 3 becomes the fixed plate 502 and the limiting plate 501, and the electric telescopic rod 401 does not need to support the first support plate 2 and the second support plate 3 when retracting.

[0037] At this point, the positions of the first support plate 2 and the second support plate 3 are fixed, and the laptop can be placed on them for use.

[0038] When it is necessary to retract the first support plate 2 and the second support plate 3, first slide the two fixed plates 502 upwards, then rotate the hook plates 9 on the two fixed plates 502 so that the limiting grooves on the hook plates 9 hook the fixed posts 10 on both sides, thereby releasing the restriction of the fixed plates 502 on the limiting plates 501.

[0039] At this time, the spring 8 is compressed, the fixed plate 502 separates from the limiting plate 501, and the limiting post 7 will ensure that the spring 8 and the fixed plate 502 will not shift in position.

[0040] Next, press the control button 404 to fully retract the electric telescopic rod 401. This will cause the rotating shaft 402 to pull the inner wall of the sliding groove, causing the connecting plate 403 to be pulled by the rotating shaft 402 and thus move, ultimately folding and storing the first support plate 2 and the second support plate 3.

[0041] This design avoids the first support plate 2 and the second support plate 3 from relying solely on the electric telescopic rod 401 for support, thereby increasing the stability of the first support plate 2 and the second support plate 3 and extending the service life of the electric telescopic rod 401.

[0042] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
