Description

Technical Field

[0001] This utility model relates to the technical field of monitor stand accessories, specifically to a foot height adjustment mechanism and a stand. Background Technology

[0002] Desktop monitors are widely used as common image output devices in daily work and life. To ensure stability and comfort during use, people usually use dedicated stands to support the monitor and adjust its height. In particular, portable hinged displays require adjustable feet to meet the angle and height adjustment needs in different situations. Existing hinged displays use a flip-open method, which lacks support or the support part only has a fixed opening angle, limiting the support angle and height. They cannot be automatically adjusted and need to be opened manually, which is inconvenient. There is a need for a support structure that can freely adjust the support height and rise and fall with the opening angle of the screen when it is open, eliminating the need for manual operation. Utility Model Content

[0003] One of the purposes of this utility model is to provide a foot pad height adjustment mechanism, which solves the problems of small height adjustment range and cumbersome manual adjustment operation of existing support bases.

[0004] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:

[0005] A foot pad height adjustment mechanism includes a first bracket, a supporting foot pad, a second bracket, a lifting drive mechanism, and a rotating mechanism. The supporting foot pad is flexibly connected to the first bracket, and the rotating mechanism is connected to the second bracket and rotatably connected to the first bracket. The lifting drive mechanism drives the supporting foot pad to move up and down. The rotating mechanism includes a rotating shaft, a spring element, and a fastener. The second bracket is connected to one end of the rotating shaft, and the middle part of the rotating shaft is rotatably connected to the first bracket. The lifting drive mechanism is mounted on the rotating shaft and is driven by the rotating shaft. The spring element is sleeved on the rotating shaft, and the fastener presses the spring element onto the rotating shaft. The mechanism can stop at any position during rotation and lifting, making it convenient to operate.

[0006] Furthermore, the lifting drive mechanism includes a first gear, a second gear, and a retainer. The first gear is fixedly sleeved on the rotating shaft, the retainer is fixed on the rotating shaft, the second gear is rotatably connected to the retainer, and the second gear meshes with the first gear. The second gear drives the support foot pad to move up and down, and transmits the motion to the lifting drive mechanism through the rotating shaft, thereby realizing the linkage between rotational motion and lifting motion.

[0007] Furthermore, the support foot pad is provided with a toothed portion, and the support foot pad is slidably connected to the first bracket. The toothed portion meshes with the second gear, thereby improving the accuracy of lifting and moving.

[0008] Preferably, the rotating mechanism further includes a pressure plate, which is sleeved on the rotating shaft and clamps the elastic element in the middle, protecting the elastic element and the compensation space. The damping magnitude can be changed by changing the number of elastic elements.

[0009] Even better, the elastic element is a disc spring, which has high elasticity, small size and low cost of use.

[0010] The rotating shaft includes a first engaging portion, a limiting portion, a rotating portion, a flange, and a second engaging portion, which are sequentially distributed along the axis of the rotating shaft. The rotating mechanism and the lifting drive mechanism are both disposed in the first engaging portion. The limiting portion is provided with a limiting groove, which cooperates with a protrusion on the side wall of the first bracket to limit the rotation range of the rotating mechanism. The rotating portion is rotatably connected to the first bracket. The flange separates the rotating portion and the second engaging portion. The second engaging portion is engaged with the second bracket. The rotating shaft transmits power and simultaneously realizes the functions of rotation and stopping at any position.

[0011] Furthermore, the first bracket includes a base plate, a support plate, a guide groove, and a guide block. The support plate is disposed on the base plate, and the support plate has a first through hole. The rotating shaft is rotatably connected in the first through hole. The guide groove is disposed on one side of the support plate, and the support foot pad is slidably connected in the guide groove. The guide block is disposed at the edge of the guide groove to prevent the support foot pad from shaking when it is raised or lowered, thereby extending its service life.

[0012] As a better option, the end of the rotating shaft is provided with a threaded portion, and the fastener is connected to the threaded portion to adjust the clamping force on the elastic element, thereby adjusting the damping magnitude.

[0013] Furthermore, the second bracket has a rotation angle range of 0°-180° relative to the first bracket, providing a wide range of height adjustment and supporting the screen to be opened into tablet mode.

[0014] The second objective of this utility model is to provide a base that solves the problem of limited adjustable height range of existing monitor bases.

[0015] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:

[0016] A base, including the aforementioned foot pad height adjustment mechanism, can adjust the height of the screen in conjunction with opening and closing the screen, simplifying operation.

[0017] The beneficial effects of this utility model are as follows:

[0018] (1) The foot pad height adjustment mechanism is equipped with a rotating mechanism and a lifting drive mechanism. The lifting drive mechanism drives the support foot pad to rise and fall through the rotating motion from the second bracket via the rotating shaft, thereby realizing the adjustment of the support height. At the same time, the elastic sheet applies pressure to the rotating shaft, which can self-lock after the adjustment is completed. The operation is convenient. The height of the support foot pad is driven by the rotating motion when it is opened, which simplifies the operation steps and makes it more convenient to use.

[0019] (2) The rotating mechanism of the foot pad height adjustment mechanism is equipped with elastic elements and pressure plates. The elastic elements are pressed onto the rotating shaft by fasteners, which can effectively buffer and absorb the impact force during the rotation process and reduce the wear between the parts. The rotating shaft is equipped with a limiting part that cooperates with the protrusion on the side wall of the first bracket, which can limit the rotation range of the rotating mechanism and prevent structural damage caused by excessive rotation. The sliding connection between the support foot pad and the first bracket and the stable transmission of gear meshing make the entire foot pad height adjustment mechanism stable during use and have a long service life. The gear meshing drives the support foot pad to lift and lower, and the accuracy and stability of the lifting and lowering movement are high. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments in the application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0028] Example 1

[0029] like Figures 1-5 As shown, this embodiment discloses a foot pad height adjustment mechanism, including a first bracket 1, a supporting foot pad 2, a second bracket 5, a lifting drive mechanism, and a rotating mechanism. The supporting foot pad 2 is flexibly connected to the first bracket 1, and the rotating mechanism is connected to the second bracket 5. The rotating mechanism is rotatably connected to the first bracket 1, and the lifting drive mechanism drives the supporting foot pad 2 to move up and down. The rotating mechanism includes a rotating shaft 4, a spring element 8, and a fastener 6. The second bracket 5 is connected to one end of the rotating shaft 4, and the middle part of the rotating shaft 4 is rotatably connected to the first bracket 1. The lifting drive mechanism is mounted on the rotating shaft 4, and... The lifting drive is driven by the rotating shaft 4. The elastic element 8 is sleeved on the rotating shaft 4. The fastener 6 presses the elastic element 8 onto the rotating shaft 4. The first bracket 1 is used to fix the stationary part of the screen when it is opened and closed. The second bracket 5 includes a connecting plate 52 and a side plate 51. The connecting plate 52 connects to the opening and closing part of the screen. The rotating mechanism is pressured by the elastic element 8 to form damping that prevents the second bracket 5 from rotating, so that the screen can be stopped at any angle. The rotating shaft 4 on the rotating mechanism transmits the rotational motion to the lifting drive mechanism, which drives the support foot pad 2 to move up and down. The operation is convenient.

[0030] Furthermore, the lifting drive mechanism includes a first gear 10, a second gear 11, and a retainer 9. The first gear 10 is fixedly sleeved on the rotating shaft 4, the retainer 9 is fixed on the rotating shaft 4, and the second gear 11 is rotatably connected to the retainer 9 and meshes with the first gear 10. The second gear 11 drives the support foot pad 2 to move up and down. Through gear meshing, the rotational movement of the second bracket 5 is transmitted to the second gear 11 through the rotating shaft 4. The second gear 11 drives the support foot pad 2 to adjust its height. The height adjustment is completed by using the rotational power, which is convenient to use and eliminates the need for users to adjust the height separately.

[0031] Preferably, the retainer 9 is provided with a hole for connecting the rotating shaft 4 and the shaft body 3 of the second gear 11. The shaft body 3 passes through both the retainer 9 and the second through hole 14 on the first bracket 1, so that the retainer 9 does not rotate with the rotating shaft 4, ensuring stable meshing and transmission between the second gear 11 and the toothed part 21.

[0032] Furthermore, the support foot pad 2 is provided with a toothed part 21. The support foot pad 2 is slidably connected to the first bracket 1. The toothed part 21 meshes with the second gear 11. The toothed engagement improves the accuracy of adjustment. The end of the support foot pad 2 is provided with a rubber foot, which can directly contact the ground. The size of the rubber foot is larger than the toothed part 21 to prevent it from falling off in the opposite direction when moving.

[0033] Preferably, the rotating mechanism further includes a pressure plate 7, which is sleeved on the rotating shaft 4 and clamps the elastic element 8 in the middle, thus protecting the elastic element 8 and compensating for excess space. By controlling the number of elastic elements 8, the magnitude of the rotational damping can be controlled, thereby expanding the range of applications.

[0034] More preferably, the elastic element 8 is a disc spring. The disc spring can store and release energy through its own elastic deformation. It has the functions of providing load, isolation, buffering, shock absorption, sealing, fixing and compensation. When used here, it can improve the damping during rotation and realize arbitrary adjustment of the rotation angle.

[0035] More preferably, the elastic element 8 is composed of multiple disc springs stacked together to form a disc spring group fixed on the rotating shaft 4. The resistance to the rotation of the rotating shaft 4 is increased by multiple disc springs, ensuring that it can support screens of different weights.

[0036] Furthermore, the rotating shaft 4 includes a first engaging portion 41, a limiting portion 43, a rotating portion 45, a flange 46, and a second engaging portion 47 arranged sequentially along the axis of the rotating shaft 4. The rotating mechanism and the lifting drive mechanism are both disposed in the first engaging portion 41. The limiting portion 43 is provided with a limiting groove 44, which cooperates with the protrusion 15 on the side wall of the first bracket 1 to limit the rotation range of the rotating mechanism. The rotating portion 45 is rotatably connected to the first bracket 1. Specifically, the rotating portion 45 is rotatably connected in the first through hole 13. The flange 46 separates the rotating portion 45 and the second engaging portion 47. The second engaging portion 47 is engaged with the second bracket 5. Both the first engaging portion 41 and the second engaging portion 47 are formed by opening blind grooves along the axial direction of the round shaft. A stable engaging is formed through the blind groove portion. The limiting portion 43 is an annular protrusion on the side wall of the rotating shaft 4, which can limit its axial movement. The second engaging portion 47 is connected to the locking hole on the side plate 51 of the second bracket 5, so that the second bracket 5 can drive the rotating shaft 4 to rotate.

[0037] Preferably, the flanges 46 are arranged in two spaced-apart configurations, with a space between the two flanges 46 for mounting other components and for increasing the axial length.

[0038] Furthermore, the first support 1 includes a base plate 101, a support plate 12, a guide groove 16, and a guide block 17. The support plate 12 is disposed on the base plate 101 and has a first through hole 13. The rotating shaft 4 is rotatably connected in the first through hole 13. The guide groove 16 is disposed on one side of the support plate 12, and the support foot pad 2 is slidably connected in the guide groove 16. The guide block 17 is disposed at the edge of the guide groove 16. The support plate 12 is perpendicular to the base plate 101, and the guide block 17 contacts the back of the toothed part 21 and is opposite to the other side of the lifting drive mechanism, preventing the support foot pad 2 from shifting to one side due to lateral driving force, thereby improving the stability of the movement of the support foot pad 2.

[0039] Preferably, the end of the rotating shaft 4 is provided with a threaded part 42, and the fastener 6 is connected to the threaded part 42 for fixing and pre-pressing the elastic element 8 to adjust the damping on the rotating shaft 4.

[0040] Furthermore, the second bracket 5 has a rotation angle range of 0°-180° relative to the first bracket 1, which supports the travel of the foot pad 2 and enables the screen to unfold into a tablet state.

[0041] The working process of the foot pad height adjustment mechanism is as follows:

[0042] Rotating the second bracket 5 drives the rotating shaft 4 to rotate. The elastic element 8 on the rotating shaft 4 applies pressure to prevent the rotating shaft 4 from rotating, so that the second bracket 5 can stop at any position. At the same time, the rotating shaft 4 drives the first gear 10 of the lifting drive mechanism to rotate. The first gear 10 drives the second gear 11 to rotate. The second gear 11 drives the support foot pad 2 to move up and down through the toothed part 21, realizing the linkage between the rotation action and the lifting action. After the rotating shaft 4 stops, the elastic force on the elastic element 8 prevents the support foot pad 2 from falling.

[0043] Example 2

[0044] This embodiment also discloses a base, including a foot pad height adjustment mechanism and an opening and closing screen. The foot pad height adjustment mechanism is installed on the opening and closing screen. The first bracket 1 is connected to the seat plate part of the opening and closing screen, and the second bracket 5 is connected to the rotating opening and closing part of the opening and closing screen. When the screen is opened, it can drive the supporting foot pad 2 to move up and down synchronously, and can stop at any position. It is easy to use and operate.

[0045] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and any modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
