Description

Technical Field

[0001] The utility model belongs to the technical field of display fixing, and in particular relates to a fixing device for a dual-screen notebook. Background Art

[0002] Laptops usually appear in single-screen form, but with the improvement of hardware performance and in certain special fields, the demand for dual-screen laptops is increasing. For example, they are widely used in special vehicles and equipment such as vehicles, ships, and airplanes.

[0003] A dual-screen notebook is a laptop computer with two display screens. The difference from a single-screen notebook computer is that it has an additional screen display, and the secondary screen is connected to the main screen through a hinge mechanism. When unfolded, it is usually located on one side of the main screen with a cantilever design. In order to ensure the convenience and feel of flipping the secondary screen, not too much torque is required to open the secondary screen. This makes the notebook components and LCD screen susceptible to external forces during work. Therefore, it is very necessary to use a fixing device for fixing the notebook and the secondary screen.

[0004] Currently, dual-screen notebook fixing devices usually fix the main unit on an operating table. A vertical plate is provided on the operating table to fit the main screen after it is unfolded, and a locking device is used to clamp the main screen and the secondary screen on the vertical plate to ensure the fixing effect.

[0005] For example, the Chinese invention patent application with patent publication number CN117167595A and publication date 2023.12.05 discloses a fixing device for a dual-screen notebook, the structure of which includes a host fixing mechanism and a display fixing mechanism; the display locking device is a double rocker mechanism, including a clamping block, a long screw, a support rod, a handle, a pad, a rivet, a base, and a buffer pad.

[0006] The general structural principle of the dual-screen notebook fixing device in this utility model patent is as follows: the handle serves as a connecting rod mechanism, and by raising and lowering the handle, the opening angle of the clamping block can be controlled to clamp and release the screen, and the silicone rubber material on the contact surface is used to exert its damping properties to fix the screen.

[0007] However, in actual use, the fixing device still has at least the following two deficiencies, in other words, these are the technical problems to be solved by the present utility model.

[0008] 1. The main unit fixing mechanism clamps the main unit from the side through the third locking device, and cannot limit the main unit forward and backward by itself.

[0009] 2. The connecting rod mechanism clamps the screen by folding. It only has clamping and opening states, and the clamping strength cannot be adjusted, which can easily emboss the screen.

[0010] Therefore, in summary, there is an urgent need for a new type of fixing device that can clamp the corner of the host end and has adjustable screen clamping force. Utility Model Content

[0011] The utility model provides a fixing device for a dual-screen notebook computer, which can achieve the following by arranging a clamping limit plate unit and an adjustable pressure block unit on a mounting platform and a fixed vertical plate: 1. The clamping limit plate unit fixes the main unit by engaging the corners of the main unit end, which not only ensures the left and right position stability of the main unit from the side end but also limits the front and rear positions of the main unit, so that the installation of the main unit is stable and firm; 2. The adjustable pressure block unit is arranged on the fixed vertical plate and is used to clamp the periphery of the display screen to prevent the display screen from shaking or covering under force. The adjustable pressure block unit is hingedly arranged and clamps the display screen by plugging it in and pressing it, thereby ensuring clamping stability. At the same time, the plug-in clamping force is highly controllable, and the feedback on the clamping effect is strong, thereby reducing damage to the display screen.

[0012] The technical solution adopted by the present invention to solve the above-mentioned problem is: a fixing device for a dual-screen notebook, the structure of which includes a mounting platform and a fixed vertical plate, and also includes a clamping limit plate unit arranged on the mounting platform and used to engage the corner of the host end, and an adjustable pressure block unit arranged on the fixed vertical plate and used to clamp the display screen.

[0013] A further preferred technical solution is that the adjustable pressure block unit includes a fixed block arranged on the fixed vertical plate, a rotating block hingedly arranged on the fixed block, two sockets respectively arranged on the fixed block and the rotating block, and an elastic plug rod arranged on the two sockets and used to adjust the clamping strength of the rotating block on the display screen.

[0014] A further preferred technical solution is that the clamping limit plate unit includes an opening block arranged on the mounting table and located at both side ends of the main machine, an L-shaped plate arranged on the opening block and used to fit the corners of the main machine end, and a clamping rod inserted into the opening block and used to support the L-shaped plate.

[0015] A further preferred technical solution is that: the adjustable pressure block unit further includes a pad provided at the lower end of the fixed block and used for supporting the display screen.

[0016] A further preferred technical solution is that the adjustable pressure block unit further includes a protruding block provided on the elastic insertion rod and used for engaging with the insertion hole at the position of the fixed block.

[0017] A further preferred technical solution is that the adjustable pressure block unit further includes a limiting ring groove provided on the rotating block and close to the insertion hole and used to block the protruding block.

[0018] A further preferred technical solution is that the adjustable pressure block unit further includes a silicone pad provided on the rotating block and the pad and used for clamping the display screen.

[0019] A further preferred technical solution is that the adjustable pressure block unit further includes a fixed rotating shaft provided on the fixed block and used for hingedly connecting the rotating block, and a screw provided on the fixed rotating shaft.

[0020] A further preferred technical solution is that: the clamping and limiting plate unit further includes a rubber sleeve which is sleeved on the clamping rod and is used to support the L-shaped plate.

[0035] The following description is merely a preferred embodiment of the present invention and is not intended to limit the scope of the present invention.

[0036] As attached Figure 1-8 As shown, a fixing device for a dual-screen notebook computer comprises a mounting platform 11 and a fixing vertical plate 12, a clamping limit plate unit 1 arranged on the mounting platform 11 and used to engage the corner of the host a end, and an adjustable pressure block unit 2 arranged on the fixing vertical plate 12 and used to clamp the display screen b.

[0037] In this embodiment, the mounting platform 11 is used to prevent the host a, and the fixing plate 12 is set on the mounting platform 11 to support the display screen b in the open state. The angle between the fixing plate 12 and the mounting platform 11 is slightly larger than a right angle to accommodate the display screen b in the open state for easy viewing and operation.

[0038] In addition, the clamping and limiting plate unit 1 is arranged on the mounting table 11 and is located at the four end corners of the host a, so as to clamp and limit the four end corners of the host a. By clamping the side ends of the host a, the left and right directions of the host a are restricted and fixed, and by limiting the front and rear positions of the host a, the front and rear positions of the host a are limited, so as to achieve the fixation of the host a. When the environment shakes or vibrates greatly, the host a is less affected by the deflection caused by the outside world.

[0039] Finally. The adjustable pressure block unit 2 is arranged on the fixed plate 12, and is located around the main screen and the auxiliary screen of the display screen b. The unfolded display screen b is fixed by rotating and clamping. The adjustable pressure block unit 2 is arranged on the four sides of the display screen b. The unfolded display screen b fits with the fixed plate 12. The adjustable pressure block unit 2 is rotated to clamp the display screen b, and then the clamping state is fixed by plugging. The plugging makes the clamping force of the adjustable pressure block unit 2 more flexible, and the force can be adjusted. When the fit between the display screen b and the fixed plate 12 is not high, the adjustable pressure block unit 2 is more difficult to clamp and fix. It can provide timely feedback and adjustment to adjust the unfolding angle of the display screen b, reducing the damage to the display screen b caused by erroneous operation. It is better to plug and fix the adjustable pressure block unit 2 at the front end of the unfolded display screen b, which reduces the operating space required for the clamping operation, compresses the operating volume, and has a better use effect.

[0040] The adjustable pressure block unit 2 includes a fixed block 201 arranged on the fixed vertical plate 12, a rotating block 202 hingedly arranged on the fixed block 201, two sockets 203 respectively arranged on the fixed block 201 and the rotating block 202, and an elastic insertion rod 204 arranged on the two sockets 203 and used to adjust the clamping strength of the rotating block 202 on the display screen b.

[0041] In this embodiment, the fixed block 201 is arranged on the fixed vertical plate 12 and is located on the outside of the display screen b. The rotating block 202 is hinged to the fixed block 201 and reserves space for placing the display screen b. It is opened and closed by rotation, thereby limiting the display screen b. The sockets 203 are correspondingly arranged on the fixed block 201 and the rotating block 202. When the fixed block 201 and the rotating block 202 are folded and closed, the two sockets 203 are in the same straight line and are used to insert the elastic insertion rod 204. The elastic insertion rod 204 fixes the folded state of the fixed block 201 and the rotating block 202 through the socket 203. The display screen b is located between the fixed block 201 and the rotating block 202 and is fixed by the elastic insertion rod 204. The elastic insertion rod 204 has a certain deformation ability, and the clamping tightness is more flexible. The farther the aperture of the insertion hole 203 on the fixing block 201 is from the display screen b, the smaller the aperture is, thereby ensuring the clamping effect.

[0042] The clamping limit plate unit 1 includes an opening block 101 arranged on the mounting platform 11 and located at both sides of the host a, an L-shaped plate 102 arranged on the opening block 101 and used to fit the corner of the end of the host a, and a clamping rod 103 inserted into the opening block 101 and used to support the L-shaped plate 102.

[0043] In this embodiment, the perforated blocks 101 are disposed at the four corners of the console a. The L-shaped plates 102 are used to fit over the corners of the console a to limit the position of the four corners. The L-shaped plates 102 can be magnetically attached to the console a. The clamping rods 103 are inserted into the perforated blocks 101 and press against the L-shaped plates 102 to clamp the console a and define its front, back, left, and right orientations. The front diameter of the clamping rods 103 can be slightly smaller than the rear diameter. Furthermore, when the console a is slightly smaller, the clamping rods 103 can also clamp it securely.

[0044] The adjustable pressure block unit 2 further includes a pad 205 disposed at the lower end of the fixed block 201 and used to support the display screen b.

[0045] In this embodiment, the pad 205 fits closely with and supports the back of the display screen b, so that the clamping stability of the fixed block 201 and the rotating block 202 is better, while reducing the collision between the display screen b and the fixed vertical plate 12 due to external shaking.

[0046] The adjustable pressure block unit 2 further includes a protruding block 206 disposed on the elastic insertion rod 204 and configured to engage with the insertion hole 203 at the position of the fixed block 201 .

[0047] In this embodiment, the function of the protruding block 206 is to increase the engagement strength between the elastic rod 204 and the fixed block 201. At the same time, the protruding block 206 is larger than the insertion hole 203 on the rotating block 202, which can effectively prevent the elastic rod 204 from being lost and make fixation more convenient.

[0048] The adjustable pressure block unit 2 further includes a limiting ring groove 207 provided on the rotating block 202 and close to the insertion hole 203 and used to block the protruding block 206 .

[0049] In this embodiment, the limiting ring groove 207 is used to allow the protruding block 206 to be retracted into the limiting ring groove 207 without being separated from the rotating block 202, and has a guiding function, thereby increasing the insertion stability of the elastic insertion rod 204.

[0050] The adjustable pressure block unit 2 further includes a silicone pad 208 disposed on the rotating block 202 and the backing plate 205 and used for clamping the display screen b.

[0051] In this embodiment, the silicone pad 208 serves to clamp the display screen b, thereby increasing the clamping force and reducing the damage to the display screen b.

[0052] The adjustable pressure block unit 2 further includes a fixed rotation shaft 209 provided on the fixed block 201 and used for hingedly connecting the rotating block 202 , and a screw 210 provided on the fixed rotation shaft 209 .

[0053] In this embodiment, the fixed shaft 209 and the screw 210 are used to detachably hinge the fixed block 201 and the rotating block 202. When the thickness of the display screen b changes, the rotating block 202 can be replaced accordingly for clamping and fixing, which is more practical.

[0054] The clamping and limiting plate unit 1 further includes a rubber sleeve 104 sleeved on the clamping rod 103 and used to support the L-shaped plate 102 .

[0055] In this embodiment, the rubber sleeve 104 serves to increase the friction of the clamping rod 103 to prevent loss, ensure the clamping strength, and reduce the loss of the L-shaped plate 102 .

[0056] The clamping rod 103 is a threaded rod.

[0057] In this embodiment, the clamping rod 103 is configured as a threaded rod, and the through hole of the opening block 101 is correspondingly configured as a threaded hole, so that the clamping strength of the clamping rod 103 is more flexible, the precision is higher, and the operation is more convenient.
