Description

Technical Field

[0001] The invention belongs to the technical field of computer accessories, and in particular relates to a foldable support chassis for multiple display screens used for software development, which is mainly used for supporting and protecting multiple display screens when the multiple display screens are in use. Background Art

[0002] In software development, software developers need to frequently write code, display programming results, and query data. Therefore, in order to facilitate the operation of software developers, one workstation is often equipped with three computer monitors to achieve multi-screen operation of software developers, thereby improving the work efficiency of software developers. At the same time, in order to improve the stability of using multiple monitors, people have designed a chassis that can support three monitors at the same time.

[0003] As disclosed in existing public documents, CN110748755A - A computer multi-screen installation structure for computer software development, discloses a fixing plate, the bottom end of which is fixedly mounted with a bending plate, the bottom of which is threadedly connected to a threaded rod, the top end of which is rotatably connected to an extrusion plate, the top end of which is fixedly mounted with a main support rod, the outer periphery of which is provided with a sleeve, the rear end of which is threadedly connected to a fixing bolt. This computer multi-screen installation structure for computer software development can stably and centrally fix three computer screens on a desk, which is beneficial for software developers to perform multi-screen operations, improves work efficiency and user comfort, and can adjust the position and horizontal and vertical angles of the screen, and change the degree of flexibility of the rotation to keep the screen stable.

[0004] Although the base described in the above-mentioned public documents can realize the simultaneous support of three display screens in actual use, which is convenient for software developers to meet the multi-screen usage requirements, the above-mentioned support base still has the following shortcomings in actual use:

[0005] 1. The support base described in existing public documents always keeps the three display screens in a fully extended state when in use and cannot be stored when not in use. This results in a cramped workstation space and easily creates a sense of oppression for workers, making it difficult for them to work comfortably.

[0006] 2. When the support base described in the existing public literature is in use, the three display screens are always in a fixed state, which inevitably results in the three display screens being far away from the staff, making it difficult for the staff to carefully and fully analyze and study the data on a particular display screen;

[0007] 3. The support base in existing public documents is positioned only by two clamping mechanisms at the bottom. This results in poor overall stability of the display screen during use, and the display screen is prone to shaking.

[0008] Therefore, it is necessary to improve the existing technology to solve the above technical problems. Summary of the Invention

[0009] The purpose of the present invention is to provide a foldable multi-display support base for software development, which can fold and store the display screen, adjust the display screen position conveniently and has strong overall stability, thereby solving the problems of the existing support base in actual use, such as being difficult to fold and store, difficult to adjust the display screen position and having poor overall stability.

DETAILED DESCRIPTION

[0059] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0060] See also Figure 1-2 As shown, the present invention is a foldable support chassis for multiple display screens for software development, comprising a main clamping mechanism 1, an L-shaped support plate 2 and an auxiliary clamping mechanism 3. The two auxiliary clamping mechanisms 3 are symmetrically arranged on both sides of the main clamping mechanism 1. The upper end of the L-shaped support plate 2 is detachably connected to the rear end of the main clamping mechanism 1. At the same time, the other end of the L-shaped support plate 2 extends from the lower end of the main clamping mechanism 1 to the front of the main clamping mechanism 1 and is connected to the reinforcement bar 201 in a cross shape. The reinforcement bar 201 can increase the support area and improve the stability of the support. The main clamping mechanism 1 and the auxiliary clamping mechanism 3 are connected by a storage mechanism 5. The rear side of the main clamping mechanism 1 is also connected to a driving mechanism 4.

[0061] It can be seen from the accompanying drawings that the above components constitute the basic structure of the present device, wherein the main clamping mechanism 1 is used to clamp the main display screen, the auxiliary clamping mechanism 3 is used to clamp the auxiliary display screen, the L-shaped support plate 2 is used to support the entire device, and the coordinated arrangement of the storage mechanism 5 and the driving mechanism 4 can realize the folding and storage of the auxiliary clamping mechanism 3 toward the rear end of the main clamping mechanism 1.

[0062] See also Figure 3 、 4 As shown in Figures 9, 10, 11 and 12, the storage mechanism 5 includes a movable rod 501, a fixed rod 502, a locking frame 503 and an adjusting rod 504. One end of the movable rod 501 is slidably sleeved in the fixed rod 502. A first rectangular opening groove 5022 that is connected to the inner cavity of the fixed rod 502 is provided on the rear side surface of the fixed rod 502 along the long side direction. The inner cavity here refers to the chamber of the fixed rod 502 for accommodating the movable rod 501. A first fixing ear 5011 is fixedly connected to a side surface of the movable rod 501 near one end of the fixed rod 502. The first fixing ear 5011 is clearance-fitted in the first rectangular opening groove 5022. The setting of the first rectangular opening groove 5022 can play a role in limiting and guiding the movement of the first fixing ear 5011.

[0063] The fixing rods 502 on both sides of the first fixing ear 5011 are slidably sleeved with locking frames 503, and the top surface of the locking frame 503 is screwed with a first locking bolt 5031. One end of the first locking bolt 5031 passes through the locking frame 503 and contacts the top surface of the fixing rod 502. The setting of the first locking bolt 5031 can adjust the movable distance of the movable rod 501 in the fixing rod 502 according to the width of the auxiliary display screen. Specifically, in the two states of the auxiliary clamping mechanism 3 being fully unfolded and fully folded, the position of the locking frame 503 is determined, and then it is locked by the first locking bolt 5031. In subsequent operations, the two locked locking frames 503 can be automatically positioned on both sides of the first fixing ear 5011;

[0064] A first through hole 5021 is provided on the end surface of the fixed rod 502 farther from the movable rod 501. The first through hole 5021 movably cooperates with the second movable frame 1021 in the main clamping mechanism 1. This arrangement enables one end of the fixed rod 502 to rotate about the second movable frame 1021.

[0065] The two second movable frames 1021 are symmetrically arranged at the middle positions of the left and right sides of the first set box 102;

[0066] The driving mechanism 4 includes a rectangular housing 401 and a screw rod 404. The screw rod 404 is arranged inside the rectangular housing 401, and both ends of the screw rod 404 are rotatably connected to the end surface of the rectangular housing 401 through rolling bearings. A movable sleeve 403 is spirally sleeved on the screw rod 404, and second fixing ears 407 are symmetrically provided on both sides of the movable sleeve 403, which are clearance-matched with second rectangular opening grooves 405 on the side surface of the rectangular housing 401. The provision of the second rectangular opening grooves 405 can serve as a limit guide for the movement of the second fixing ears 407. One end of the screw rod 404 slides through one end of the rectangular housing 401 and is embedded with the output end of the motor 406. The motor 406 is fixedly connected to the outer wall of the rectangular housing 401.

[0067] A mounting flange 402 is provided on the outer wall of the other end of the rectangular housing 401 where the motor 406 is provided. The mounting flange 402 is fixedly connected to the rear side of the first housing 102 by bolts. The provision of the mounting flange 402 facilitates the disassembly and installation of the rectangular housing 401.

[0068] A controller 203 is also fixedly mounted on the top surface of the horizontal plate of the L-shaped support plate 2, and the controller 203 is electrically connected to the motor 406 via a conductive line;

[0069] Both ends of the adjusting rod 504 are fixedly connected to a first movable frame 5041. The first movable frame 5041 is used to movably cooperate with the first fixing ear 5011 and / or the second fixing ear 407. This arrangement allows both ends of the adjusting rod 504 to rotate freely, thereby preventing the adjusting rod 504 from getting stuck during rotation.

[0070] When the above arrangement is in use, the motor 406 is controlled to rotate by the controller 203. Under the action of the rotation of the motor 406, the screw rod 404 starts to rotate. Because of the spiral matching setting between the screw rod 404 and the movable sleeve 403, under the action of the rotation of the screw rod 404, the movable sleeve 403 can be driven to move on the axis of the screw rod 404. During the movement, the adjusting rod 504 moves synchronously to drive the movable rod 501 to slide on the fixed rod 502. At the same time, one end of the fixed rod 502 rotates with the second movable frame 1021 as the axis, thereby realizing the folding and storage of the auxiliary clamping mechanism 3 to the rear of the main clamping mechanism 1 and the complete expansion of the auxiliary clamping mechanism 3.

[0071] See also Figure 3-5 As shown in Figures 11 and 11 , the main clamping mechanism 1 includes a first L-shaped clamping plate 101 and a first set box 102 . The middle portion of the rear side surface of the vertical plate of the first L-shaped clamping plate 101 is fixedly connected to one end of the first support plate 1011 by bolts.

[0072] A first vibration damping plate 1012 is provided on the side of the horizontal plate that is relatively close to the two first L-shaped clamping plates 101. The first vibration damping plate 1012 is arranged in a right triangle, and the inclined surface of the triangle is arranged on the side of the vertical plate close to the first vibration damping plate 1012. The first vibration damping plate 1012 is made of rubber material and is used to provide vibration reduction and protection for the display screen during clamping. The right triangle arrangement can make the display screen clamping more stable.

[0073] The first set box 102 is set with a closed lower end. The other end of the first support plate 1011 located below the first set box 102 is fixedly connected to the bottom surface of the first set box 102. The other end of the first support plate 1011 located above the first set box 102 is slidably sleeved in the first set box 102. A first return spring 1024 is provided inside the first set box 102. The two ends of the first return spring 1024 are respectively fixedly connected to the first set box 102 and the first support plate 1011. This arrangement can realize the free movement of the first support plate 1011 in the first set box 102, thereby realizing corresponding adjustment according to the height of the display screen. The arrangement of the first return spring 1024 can realize automatic reset, thereby improving the clamping effect.

[0074] A second locking bolt 1022 is screwed onto the upper end of the rear side of the first housing 102. One end of the second locking bolt 1022 passes through the first housing 102 and contacts a side wall of the first support plate 1011. The second locking bolt 1022 can be automatically locked and positioned after the first housing 102 and the first support plate 1011 are adjusted.

[0075] A convex column 1023 is symmetrically provided at the lower end of the rear side surface of the first set box 102. The convex column 1023 is loosely fitted in the heterodyne slot 204 on the top surface of the L-shaped support plate 2. This arrangement enables detachable installation between the first set box 102 and the L-shaped support plate 2. The heterodyne slot 204 refers to a slot with different radial dimensions at both ends. When in use, the convex column 1023 is inserted from the large aperture at the upper end of the heterodyne slot 204. With the action of gravity, the convex column 1023 automatically slides into the small aperture at the lower end of the heterodyne slot 204 to achieve installation.

[0076] When the above arrangement is in use, the staff first presses the lower end of the main display screen against the first L-shaped clamping plate 101 below, then pulls the first L-shaped clamping plate 101 above so that the first L-shaped clamping plate 101 above is engaged with the upper edge of the main display screen, and then tightens the second locking bolt 1022 to achieve the installation and fixation of the main display screen.

[0077] See also Figure 6-8 As shown, the auxiliary clamping mechanism 3 includes a second L-shaped clamping plate 301 and a second set box 302. The middle part of the rear side surface of the vertical plate of the second L-shaped clamping plate 301 is fixedly connected to one end of the second support plate 3011 by bolts;

[0078] A second vibration damping plate 3012 is provided on the side of the horizontal plate that is relatively close to the second L-shaped clamping plate 301. The second vibration damping plate 3012 is arranged in a right triangle shape, with the inclined surface of the triangle being arranged on the side close to the vertical plate of the second vibration damping plate 3012. It is made of rubber material and is used to provide vibration damping and protection for the display screen during clamping. The right triangle arrangement can make the display screen clamping more stable.

[0079] The second housing 302 is closed at its lower end. The other end of the second support plate 3011 located below the second housing 302 is fixedly connected to the bottom surface of the second housing 302. The other end of the second support plate 3011 located above the second housing 302 is slidably sleeved in the second housing 302. A second return spring 3024 is provided inside the second housing 302. The two ends of the second return spring 3024 are respectively fixedly connected to the second housing 302 and the second support plate 3011. This arrangement enables the second support plate 3011 to move freely in the second housing 302, thereby achieving corresponding adjustment according to the height of the display screen. The arrangement of the second return spring 3024 can achieve automatic reset, thereby improving the clamping effect.

[0080] A third locking bolt 3022 is screwed onto the upper end of the rear side of the second housing 302. One end of the third locking bolt 3022 passes through the second housing 302 and contacts a side wall of the second support plate 3011. The third locking bolt 3022 can automatically lock and position the second housing 302 and the second support plate 3011 after adjustment.

[0081] When the above arrangement is in use, the staff first presses the lower end of the auxiliary display screen against the second L-shaped clamping plate 301 below, then pulls the upper second L-shaped clamping plate 301 so that the upper second L-shaped clamping plate 301 is engaged with the upper edge of the auxiliary display screen, and then tightens the third locking bolt 3022 to achieve the installation and fixation of the auxiliary display screen.

[0082] See also Figure 6-10 As shown, an assembly column 505 is provided on one side of the end of the movable rod 501 farther from the fixed rod 502, and the assembly column 505 is fixedly connected to the movable rod 501 through a connecting column 5053;

[0083] A rectangular limiting groove 5052 is provided on one side of the assembly post 505 near the main clamping mechanism 1. The rectangular limiting groove 5052 is used to loosely fit the limiting block 3021 in the middle of the rear side of the second housing 302. The limiting block 3021 is provided with a second through hole 3023. Furthermore, a third through hole 5054 is provided on the assembly post 505 above and below the rectangular limiting groove 5052, which is aligned with the second through hole 3023.

[0084] The second through hole 3023 and the third through hole 5054 are fixed together by a latch 5051. The latch 5051 can achieve the limited fixation between the assembly column 505 and the limit block 3021.

[0085] Universal wheels 3013 are symmetrically mounted on the bottom surface of the second L-shaped clamping plate 301 below the auxiliary clamping mechanism 3. The arrangement of the universal wheels 3013 facilitates the movement of the auxiliary clamping mechanism 3.

[0086] Two guide strips 3014 are symmetrically provided on the bottom surface of the second L-shaped clamping plate 301 between the two universal wheels 3013;

[0087] Two guide plates 202 are also provided on the horizontal plate of the L-shaped support plate 2 in parallel with the reinforcement strip 201. The top surfaces of the two guide plates 202 are provided with guide grooves 205 for respectively fitting with the two guide strips 3014. This arrangement can play a role of limiting and guiding when the guide plates 202 move;

[0088] The L-shaped support plate 2 between the two guide plates 202 is arranged in an isosceles trapezoidal shape, which facilitates the universal wheel 3013 to pass through the L-shaped support plate 2;

[0089] When the above arrangement is in use, when it is necessary to pay attention to observing the auxiliary display screen, the staff only needs to pull out the pin 5051 first, and then move the auxiliary clamping mechanism 3. Under the action of the rotation of the universal wheel 3013, the auxiliary clamping mechanism 3 moves toward the L-shaped support plate 2, so that the guide plate 202 is loosely fitted in the guide groove 205. As the movement continues, the universal wheel 3013 passes through the position of the L-shaped support plate 2 to form an isosceles trapezoid, so that the auxiliary display screen is superimposed on the front side of the main display screen, which is convenient for the staff to use the auxiliary display screen.

[0090] The above are only preferred embodiments of the present invention and do not limit the present invention. Any modification to the technical solutions described in the aforementioned embodiments, any equivalent replacement of some of the technical features therein, and any modification, equivalent replacement, and improvement made are within the scope of protection of the present invention.
