[0002] Laptop computers are commonly used mobile devices in modern people's daily lives and are deeply loved by people because of their convenience in use and portability.

[0003] The conventional structure of a laptop computer is a screen and a keyboard. However, in order to improve the portability of the laptop computer, its screen size is usually not large and mostly single - screen structure. In some specific occasions, the small screen is difficult to meet the needs of users. Therefore, in the prior art, a laptop computer structure with a dual - display screen is adopted. For example, the patented technology with the publication number CN220752596U discloses a double - screen laptop computer, which relates to the field of computers. The double - screen laptop computer includes a first computer main body, a second computer main body, and a connecting device. Among them, the first computer main body is provided with a first display screen, and the second computer main body is correspondingly provided with a second display screen. The first computer main body and the second computer main body are both connected to the connecting device and can adjust the splicing state relative to the connecting device. The first display screen and the second display screen are spliced in a landscape screen state in one splicing state and in a portrait screen state in another splicing state. Through the different splicing states of the first computer main body and the second computer main body, different usage experience effects are achieved. However, in this solution, the maximum opening angle of the two display screens is 180 degrees, and users and viewers can still only use it on the same side. When it is necessary to display content to viewers in different directions, the screen direction still needs to be adjusted. Therefore, a double - screen laptop computer structure that can be freely flipped is proposed to solve the problems existing in the prior art. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a double - screen laptop computer that can be freely flipped to solve the defects or deficiencies in the prior art. By setting the main display screen on the flipping bracket, 360 - degree flipping relative to the secondary display screen can be realized, and at the same time, the main display screen can also perform 360 - degree flipping on the flipping bracket. A variety of flipping usage methods can bring a better usage experience to users.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions: It includes a main display screen 1 and a secondary display screen 2. A flipping bracket 6 is arranged on the back of the main display screen 1, and a bottom shell 3 is arranged on the back of the secondary display screen 2. Flipping grooves are arranged on the opposite sides of the bottom shell 3 and the flipping bracket 6, and a flipping hinge shaft 7 is arranged in the flipping groove. The bottom shell 3 and the flipping bracket 6 are connected through the flipping hinge shaft 7.

[0006] Further, the flipping hinge shaft 7 includes a shaft seat 71 and a rotating shaft 72. There are two rotating shafts 72 symmetrically arranged on one side of the shaft seat 71. On the other side of the shaft seat 71, there is a shaft hole for movably connecting with a connecting shaft on one side inside the flipping groove.

[0007] Further, fixing holes are provided on the rotating shaft 72 for fixedly connecting with the flipping bracket 6 and the bottom shell 3.

[0008] Further, an installation backplate 5 is also provided on the back of the main display screen 1. The installation backplate 5 is movably connected with the flipping bracket 6.

[0009] Further, a first flipping shaft groove 51 is provided in the middle of the back of the installation backplate 5. Flipping shaft holes are provided at both ends of the flipping shaft groove 51.

[0010] Further, the length of the flipping bracket 6 is one - half of the length of the installation backplate 5. Two second flipping shaft grooves 61 are symmetrically provided at the top of the flipping bracket 6. A flipping shaft 8 is provided in the second flipping shaft groove 61. The other end of the flipping shaft 8 is connected with the flipping shaft hole on the flipping shaft groove 51.

[0011] Further, a wire groove 62 is provided on the flipping bracket 6. The position of the wire groove 62 corresponds to the position of the second flipping shaft groove 61.

[0013] Further, a support frame 4 is provided on the back of the bottom shell 3. The support frame 4 is hinged with the bottom shell 3.

[0014] The working principle of the present utility model: When in normal use, it is only necessary to flip the main display screen 1 to a suitable position. There is a large damping between the rotating shaft 72 and the shaft seat 71, so free positioning can be achieved. When it is necessary to use both the main display screen 1 and the secondary display screen 2 at the same time, flip the main display screen 1 to 180 degrees to be flush with the secondary display screen 2, and then the two screens can be used for display on the same plane. When it is necessary to operate and display at the same time, there are multiple operation methods. First, pull out the support frame 4 to support the secondary display screen 2, and at the same time flip the main display screen 1 and the flipping bracket 6 together by more than 180 degrees and stop at a suitable angle according to needs. Second, flip the main display screen 1 and the flipping bracket 6 to a position less than 180 degrees. The best angle is that after the secondary display screen 2 is tilted, the flipping bracket 6 is perpendicular to the desktop. At this time, then flip the main display screen further backward on the flipping bracket 6 by more than 180 degrees until reaching a suitable angle. This method can raise the display position of the main display screen 1 and is convenient for more people to watch.

[0015] After adopting the above technical solution, the beneficial effects of the present utility model are as follows: By arranging the main display screen on the flipping bracket, it can achieve a 360-degree flip relative to the secondary display screen. At the same time, the main display screen can also perform a 360-degree flip on the flipping bracket. The multiple flipping usage methods can bring a better usage experience to the user.

Detailed Embodiments

[0027] Refer to Figures 1-9As shown in the figure, the technical solution adopted in this specific embodiment is as follows: It includes a main display screen 1 and a secondary display screen 2. A flipping bracket 6 is provided on the back of the main display screen 1, and a bottom case 3 is provided on the back of the secondary display screen 2. Flipping grooves are provided on the opposite sides of the bottom case 3 and the flipping bracket 6. A flipping hinge shaft 7 is provided in the flipping groove, and the bottom case 3 and the flipping bracket 6 are connected by the flipping hinge shaft 7. In the existing dual-screen laptops, the main display screen usually cannot be flipped at a large angle, and the two display screens are hinged together, resulting in a low degree of freedom of use. When used by multiple people, the content cannot be displayed in all directions. Therefore, in this embodiment, a relatively separable dual-display screen structure is provided. Among them, the main display screen is arranged on the flipping bracket, and the secondary display screen is fixed on the bottom case. The flipping bracket and the bottom case are movably connected through the flipping hinge shaft, and the main display screen and the secondary display screen are not directly connected. Therefore, the main display screen together with the flipping bracket can be flipped 360 degrees relative to the secondary display screen at the same time. That is, when the operator needs to show the content to the viewers on the opposite side, only need to flip the main display screen to an appropriate angle towards the viewers. At this time, the main display screen and the secondary display screen are at the same height. This is a display operation method. If the user still needs to perform more operations to show the content, or needs to raise the display height of the shown content, the flipping bracket can be flipped to a position that does not affect the operation of the secondary display screen, and then the main display screen is flipped. At this time, the main display screen and the secondary display screen are not at the same height, and the content can be displayed at a higher position, thus being more in line with different usage scenarios and having a higher degree of freedom of use.

[0028] More specifically, the flipping hinge shaft 7 includes a shaft seat 71 and a rotating shaft 72. There are two rotating shafts 72 symmetrically arranged on one side of the shaft seat 71. A shaft hole is provided on the other side of the shaft seat 71 and is movably connected to a connecting shaft on one side in the flipping groove. Fixed holes are provided on the rotating shaft 72 and are fixedly connected to the flipping bracket 6 and the bottom case 3. In this embodiment, a flipping hinge shaft with double rotating shafts is provided. One of the two rotating shafts is connected to the flipping bracket, and the other is connected to the bottom case. Therefore, when flipping, the main display screen can be flipped at a large angle to the back of the secondary display screen. It can be understood that there is a large damping between the rotating shaft and the shaft seat, such as the flipping shaft of a traditional notebook, which can achieve free positioning.

[0029] More specifically, an installation back plate 5 is further provided on the back of the main display screen 1. The installation back plate 5 is movably connected to the flipping bracket 6. The main display screen is installed on the installation back plate and is connected to the flipping bracket as a whole with the installation back plate.

[0030] More specifically, a first flipping shaft groove 51 is provided in the middle of the back of the installation back plate 5, and flipping shaft holes are provided at both ends of the flipping shaft groove 51.

[0031] More specifically, the length of the flipping bracket 6 is half of the length of the mounting backplane 5. Two second flipping shaft grooves 61 are symmetrically arranged at the top of the flipping bracket 6. A flipping shaft 8 is arranged in the second flipping shaft groove 61. The other end of the flipping shaft 8 is connected to the flipping shaft hole on the flipping shaft groove 51. The flipping of the main display screen on the flipping bracket is realized by arranging a flipping shaft to connect the mounting backplane and the flipping bracket, so that the mounting backplane can flip on the top of the flipping bracket with the flipping shaft as the axis. It can be understood that there is a large damping between the flipping shaft and the flipping shaft groove, so as to realize the positioning after the main display screen is flipped.

[0032] More specifically, a wire groove 62 is arranged on the flipping bracket 6. The position of the wire groove 62 corresponds to the position of the second flipping shaft groove 61. A wire discharging groove 63 is arranged at the top of the second flipping shaft groove 61. The wire discharging groove 63 is communicated with the wire groove 62. It can be understood that a face cover is also arranged on the flipping bracket to protect and restrain the wire groove. The signal wire of the main display screen is arranged in the wire groove and led out from the wire discharging groove at the top of the second flipping shaft groove, and then connected to the main display screen. The hidden wiring is not only beautiful but also ensures the connection effect.

[0033] More specifically, a support frame 4 is arranged on the back of the bottom shell 3. The support frame 4 is hinged to the bottom shell 3. When it is necessary to support and use the secondary display screen, the support frame can be opened to support the secondary display screen. It can be understood that a limiting mechanism, such as a retractable support rod, is arranged between the support frame and the bottom shell to restrict the opening angle of the support frame, so as to better support the whole device.

[0034] The working principle of the present utility model: When in normal use, only need to flip the main display screen 1 to a suitable position. There is a large damping between the rotating shaft 72 and the shaft seat 71, so free positioning can be realized. When it is necessary to use the main display screen 1 and the secondary display screen 2 at the same time, flip the main display screen 1 to 180 degrees to be flush with the secondary display screen 2, and then the two screens can be used for display on the same plane. When it is necessary to operate and display at the same time, there are multiple operation methods. One is to pull open the support frame 4 to support the secondary display screen 2, and at the same time flip the main display screen 1 and the flipping bracket 6 together by more than 180 degrees and stop at a suitable angle according to needs. The other is to flip the main display screen 1 and the flipping bracket 6 to a position less than 180 degrees. The best angle is that after the secondary display screen 2 is tilted, the flipping bracket 6 is perpendicular to the desktop. At this time, flip the main display screen on the flipping bracket 6 backward by more than 180 degrees until reaching a suitable angle. This method can raise the display position of the main display screen 1 and is convenient for more people to watch.

[0035] The above are only used to illustrate the technical solution of the present utility model rather than to limit it. Any other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solution of the present utility model shall be covered within the scope of the claims of the present utility model as long as they do not depart from the spirit and scope of the technical solution of the present utility model.
