Description

Technical Field

[0001] The utility model belongs to the technical field of notebook devices, and particularly relates to a left - and - right rotation mechanism for a screen. Background Technique

[0002] Currently, the folding computers mainly include mobile PCs (or portable desktops) and notebook computers. Their appearances and functions are very similar, both are folding structures. The screen is located inside the foldable cover plate, the keyboard is generally located above the main body panel, and the mouse is generally located in the middle of the lower part of the panel.

[0003] However, the unfolding forms of traditional single - screen portable terminal products can no longer meet people's requirements for display and operation effects. Especially in some special fields, it is required that the single - screen terminal products can achieve the operation of a portable notebook and also serve as a convenient touch - display working effect of a tablet computer. The existing single - screen flipping can achieve the display effect, and at the same time, the touch screen brings touch - controllable operation. However, due to the singularity of the single - screen unfolding form, the screen component and the main body are connected by a hinge. The hinge mainly plays a role in flipping and unfolding, and does not have the functions of stabilizing the screen component and facilitating touch - screen operation.

[0004] The Chinese invention patent with the patent publication number CN217355202U and the publication date of September 2, 2022 discloses a notebook computer with a rotary display screen, including a main body and a display screen movably arranged on the main body. The display screen includes a base frame, a rotating component installed on the base frame, and a screen rotatably arranged on the rotating component. The screen rotates horizontally relative to the base frame through the rotating component. The base frame is provided with a positioning member for fixing the position of the screen. Hinge components are arranged on both sides of the main body, and the base frame is hinged to the main body through the hinge components. The display screen rotates forward and backward relative to the main body through the hinge components.

[0005] The general structural principle of the flip - type notebook flipping device in this invention patent is as follows: When in use, the display screen is opened, so that the display screen rotates forward and backward relative to the main body through the hinge components for normal use. The display screen is composed of a base frame, a rotating component and a screen. The user picks up the screen upward so that the screen is separated from the base frame. The screen rotates horizontally relative to the base frame through the rotating component by any angle, and the angle range is from 0° to 180°. The position of the screen is fixed by the positioning member on the base frame.

[0006] However, during the actual use of this guiding and deviation - correcting device, there are at least the following two deficiencies, that is, the technical problems to be solved by the present utility model.

[0007] 1. Its left - and - right rotation structure is relatively complex;

[0008] 2. Its reset effect after canceling left and right rotation is achieved by paired magnets. The magnetic field generated by the above-mentioned magnets is not conducive to the normal use of the laptop. For example, it may affect the normal imaging effect of the screen.

[0009] Therefore, in summary, there is an urgent need for a new type of left and right rotation mechanism for the screen with a simple structure and a limit that does not affect the use effect. Utility Model Content

[0036] In this embodiment, the opening and closing rotation plate a is hinged to the keyboard base c, and the screen b and the keyboard base c are respectively movably connected above and below the opening and closing rotation plate a, so as to ensure the folding function of the screen b. As Figure 5 shown in the figure, the figure shows the state where the screen b is unfolded after the opening and closing rotation plate a is folded by 90°.

[0037] In addition, the fixed tube unit 1 is provided on the opening and closing rotation plate a, preferably in the middle of the screen b, for inserting the plug rod unit 2. The plug rod unit 2 is connected to the screen b. Through the insertion of the fixed tube unit 1 and the plug rod unit 2, it is ensured that the clamping groove 3 is rotatably provided on the opening and closing rotation plate a.

[0038] Finally, the fixed rod 4 is provided on the screen b, and the clamping groove 3 and the fixed rod 4 are correspondingly provided on the opening and closing rotation plate a. In the normal state, the fixed rod 4 is clamped in the clamping groove 3. When rotation is required, only slightly force is needed to separate the fixed rod 4 from the clamping groove 3. Through the insertion arrangement of the fixed tube unit 1 and the plug rod unit 2, the screen b can be rotated left and right. After rotating 180°, the fixed rod 4 and the clamping groove 3 are re - clamped for limit fixation.

[0039] The fixed tube unit 1 includes a bottom plate 101 provided on the opening and closing rotation plate a, and a fixed circular tube 102 provided on the bottom plate 101.

[0040] In this embodiment, the bottom plate 101 is connected to the opening and closing rotation plate a, and the fixed circular tube 102 is provided on the opening and closing rotation plate a for sleeving the round rod 202.

[0041] The plug rod unit 2 includes a connecting plate 201 provided on the screen b, and a round rod 202 provided on the connecting plate 201 and used for inserting into the fixed circular tube 102.

[0042] In this embodiment, the connecting plate 201 is connected to the screen b, and the round rod 202 is provided at the lower end of the connecting plate 201 and inserted into the fixed circular tube 102, so that the screen b can rotate left and right relative to the opening and closing rotation plate a.

[0043] The fixed tube unit 1 further includes mounting holes 103 provided on the bottom plate 101.

[0044] In this embodiment, the function of the mounting holes 103 is to increase the connection strength between the bottom plate 101 and the opening and closing rotating plate a, and at the same time, it can accommodate more of the opening and closing rotating plates a.

[0045] The fixed tube unit 1 further includes a rubber washer 104 provided on the fixed circular tube 102 and used for connecting the round rod 202.

[0046] In this embodiment, the function of the rubber washer 104 is to ensure the connection sealing between the fixed circular tube 102 and the round rod 202, prevent water vapor or dust from entering and affecting the internal parts or circuits of the computer. At the same time, the rubber washer 104 increases friction on the premise of ensuring the rotational freedom of the round rod 202, preventing the notebook computer from being uneven or the screen from rotating after receiving a little external force, which affects the use experience. At the same time, the easy rotation of the round rod 202 drives the fixed rod 4 on the screen b to hit the engaging groove 3, causing wear.

[0047] The plug rod unit 2 further includes a plurality of connection holes 203 provided on the connection plate 201.

[0048] In this embodiment, the function of the connection holes 203 is to ensure the connection strength between the connection plate 201 and the screen b. At the same time, the connection holes 203 enable the connection plate 201 to be adapted to the installation of different screens b, which is convenient for disassembly and has better flexibility.

[0049] The engaging groove 3 is provided on the upper surface and side surface of the opening and closing rotating plate a.

[0050] In this embodiment, the engaging groove 3 can be provided on the upper surface and side surface of the opening and closing rotating plate a, and is correspondingly arranged with the fixed rod 4, so as to limit the fixed rod 4.

[0051] Protruding blocks 5 for engaging with the fixed rod 4 are provided on the side surface and / or bottom surface of the engaging groove 3.

[0052] In this embodiment, the function of the protruding blocks 5 is to block the fixed rod 4 and prevent the fixed rod 4 from sliding out of the engaging groove 3 under force, affecting the limiting effect. Further, the engaging groove 3 can be provided on the mounting plate 7, so that the engaging groove 3 can be connected to the opening and closing rotating plate a according to requirements, with better flexibility and convenient for transportation and installation.

[0053] The opening and closing rotating plate a is further provided with a mounting groove 6 for arranging the bottom plate 101.

[0054] In this embodiment, the installation groove 6 is used to install the bottom plate 101, so that the screen b fits well with the opening and closing rotating plate a. The screen b is supported by the opening and closing rotating plate a, reducing the load-bearing burden on the fixed pipe unit 1 and the plug rod unit 2, and increasing the structural firmness and stability.

[0055] The number of the engaging grooves 3 is four, and they are respectively arranged in two on both sides of the fixed pipe unit 1.

[0056] In this embodiment, the engaging grooves 3 are respectively arranged on both sides of the fixed pipe unit 1. The paths of the engaging grooves 3 coincide with those of the fixed rods 4 after rotation. The engaging grooves 3 and the fixed rods 4 are arranged at positions farther from the middle of the screen b, so as to ensure the limiting stability. The two engaging grooves 3 on the same side can be correspondingly arranged on the same vertical line, but there are certain requirements for the width of the opening and closing rotating plate a. On the premise of restricting the width of the opening and closing rotating plate a and meeting the limiting effect, the fixed rods 4 and the engaging grooves 3 on both sides can be misaligned, as shown in the attached Figure 7 figure, so as to meet the limiting effect of the opening and closing rotating plate a with a relatively narrow width.

[0057] The embodiments of the present invention have been described in detail above with reference to the drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various modifications can be made without departing from the purpose of the present invention. These are all non-creative modifications and are protected by the patent law as long as they are within the scope of the claims of the present invention.
