DETAILED DESCRIPTION

[0042] In order to enable those skilled in the art to understand the present application more clearly, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of this application.

[0043] Please refer to Figures 2 to 6, Figure 2 shows an exploded view of the flip instrument in an embodiment of the present application; Figure 3 shows a schematic diagram of the working state of the first display screen in an embodiment of the present application; Figure 4 shows a cross-sectional view of Figure 3; Figure 5 shows a schematic diagram of the working state of the second display screen in an embodiment of the present application; Figure 6 shows a cross-sectional view of Figure 5.

[0044] As shown in Figures 2 to 6, in a first aspect of the present application, a flip instrument is provided, comprising: a housing 1; a display assembly 2, comprising at least a first display 21 and a second display 22 that are not simultaneously housed in the housing 1, the first display 21 and the second display 22 being connected to form a bent structure; a drive assembly 3, comprising a first guide rail 31 and a drive mechanism 32, the first guide rail 31 comprising at least a continuous straight line segment 311 and an arc segment 312, the drive mechanism 32 being fixedly connected to the second display 22, the drive mechanism 32 moving along the straight line segment 311 and the arc segment 312. 2 moves, driving the display screen assembly 2 to perform linear motion and rotational motion respectively; the rotation limit assembly 4 is connected to the second display screen 22, and the rotation limit assembly 4 has a first limit position and a second limit position; wherein, the display screen assembly 2 is driven by the driving assembly 3 to perform rotational motion around the rotation center 421 of the rotation limit assembly 4 between the first limit position and the second limit position, when the display screen assembly 2 is located at the first limit position, the first display screen 21 is located at the preset position, and when the display screen assembly 2 is located at the second limit position, the second display screen 22 is located at the preset position.

[0045] Preferably, the preset position is the position of the first display screen 21 or the second display screen 22 in the working state. In the embodiment of the present application, the preset position is defined as a display position. The preset position of the first display screen 21 and the preset position of the second display screen 22 can be the same or different, but are preferably the same.

[0046] In some embodiments of the present application, the shell 1 is provided with a storage cavity 11 for accommodating at least the second display screen 22. When the first display screen 21 is in a working state, that is, when the first display screen 21 is in a display position, the second display screen 22 is stored in the storage cavity 11; when the second display screen 22 is in a working state, that is, when the second display screen 22 is in a display position, the first display screen 21 is in a blind spot of the user's field of vision, for example, stored on one side of the shell.

[0047] It should be noted that the connection of the first display screen 21 and the second display screen 22 to form a curved structure means that one side of the first display screen 21 is connected to one side of the second display screen 22, and after the connection, an angle is formed between the two displays to form the curved structure. Preferably, the angle between the first display screen 21 and the second display screen 22 can be 70 degrees to 90 degrees, for example, 75 degrees, 78 degrees, 80 degrees, etc., so that the display screen assembly 2 forms a curved structure that is approximately "L"-shaped or equal to "L".

[0048] In some embodiments of the present application, the size of the second display screen 22 is larger than that of the first display screen 21. For example, in the approximately "L"-shaped bending structure shown in Figures 2 to 6, the width of the second display screen 22 is larger than the width of the first display screen 21, and the length of the first display screen 21 is the same as the length of the second display screen 22.

[0049] In some embodiments of the present application, the position of the second display screen 22 after it extends out of the housing 1 through linear motion and before it performs rotational motion is called a horizontal position. Preferably, the rotation angle of the second display screen 22 from the horizontal position to the display position is 90 degrees to 130 degrees, more preferably 105 degrees. More preferably, the sum of the rotation angle of the second display screen 22 and the angle between the two display screens is 180 degrees. For example, when the angle between the first display screen 21 and the second display screen 22 is 75 degrees, the rotation angle of the second display screen 22 is 105 degrees, so that the display position of the second display screen 22 coincides with the display position of the first display screen 21. Then, after the two display screens are switched, the user can be unaware of the offset of the display positions of each display screen, thereby providing a better experience.

[0050] In some embodiments of the present application, two drive assemblies 3 are provided, wherein two first guide rails 31 are provided on either side of the second display screen 22 and remain fixed during the movement of the display screen assembly 2. Specifically, the two first guide rails 31 are formed by providing grooves in the two end cover plates 12 on either side of the second display screen 22. The two end cover plates 12 are then enclosed by the two side cover plates 13 of the housing 1. Furthermore, two drive mechanisms 32 are provided, one on the back side of the second display screen 22, to drive the movement of the display screen assembly 2.

[0051] In some embodiments of the present application, two rotation limit components 4 are provided, each rotation limit component 4 is arranged on one side of the width of the second display screen 22, specifically, is installed on the back of the second display screen 22 along the width edge of the second display screen 22, and the rotation center 421 of each rotation limit component 4 is fixed on the shell 1, preferably fixed on the upper cover plate 14 of the shell 1.

[0052] It should be understood that the working principle of the flip instrument of the present application to switch between the first display screen 21 and the second display screen 22 is as follows:

[0053] Since the first display screen 21 and the second display screen 22 are not stored in the shell 1 at the same time, when the first display screen 21 is stored in the shell 1, the second display screen 22 is in the display position (defined as the large screen working state); conversely, when the second display screen 22 is stored in the shell 1, the first display screen 21 is in the display position (defined as the small screen working state). Then, when switching from the small-screen working state to the large-screen working state, the driving mechanism 32 performs a linear motion along the straight segment 311 of the first guide rail 31 shown, thereby driving the display screen assembly 2 to perform a linear motion to extend out of the shell 1. At this time, the second display screen 22 is in a horizontal position, and then the driving mechanism 32 continues to perform a rotational motion along the arc segment 312 of the first guide rail 31, thereby driving the display screen assembly 2 to perform a rotational motion, for example, 105 degrees clockwise. At the same time, when the display screen assembly 2 performs a rotational motion, it rotates around the rotation center 421 of the rotation limit assembly 4, that is, the rotation limit assembly 4 provides the display screen assembly 2 with a rotation center 421 and a limiting support force, so that the second display screen 22 rotates to the display position. At this time, the first display screen 21 retracts and is stored in the shell 1.

[0054] On the contrary, when switching from the large-screen working state to the small-screen working state, the driving mechanism 32 rotates along the arc segment 312 of the first guide rail 31, for example, rotates 105 degrees counterclockwise and thereby drives the display screen assembly 2 to rotate. At the same time, when the display screen assembly 2 rotates, it rotates around the rotation center 421 of the rotation limit assembly 4, that is, the rotation limit assembly 4 provides the display screen assembly 2 with a rotation center 421 and a limiting support force so that the second display screen 22 rotates to a horizontal position, and then the driving mechanism 32 continues to move linearly along the straight segment 311 of the first guide rail 31, thereby driving the second display screen 22 to move linearly to retract and be stored in the storage cavity 11. At this time, the first display screen 21 switches to the display position.

[0055] Based on the above-disclosed content, the embodiment of the present application connects the first display screen 21 and the second display screen 22 to form a bending structure, and provides a first guide rail 31 including a continuous straight segment 311 and an arc segment 312 and a driving mechanism 32 fixedly connected to the second display screen 22. When the driving mechanism 32 moves along the straight segment 311 and the arc segment 312 of the first guide rail 31, the display screen assembly 2 is driven to rotate around the rotation center of the rotation limit assembly between the first limit position and the second limit position. When the display screen assembly 2 is located at the first limit position, the first display screen 21 is located at the preset position. When the display screen assembly 2 is located at the second limit position, the second display screen 22 is located at the preset position, thereby realizing multi-dimensional switching of the first display screen 21 and the second display screen 22, improving the ritual and comfort of display screen switching, and enhancing the user experience.

[0056] In some embodiments, based on the aforementioned solution, the first guide rail 31 includes a continuous straight segment 311, a first curved segment 312A, and a second curved segment 312B. The ends of the first curved segment 312A smoothly connect to the straight segment 311 and the second curved segment 312B, respectively, thereby achieving a smooth transition between the straight segment 311 and the second curved segment 312B. The center of curvature of the first curved segment 312A is away from the display screen assembly 2, while the center of curvature of the second curved segment 312B is closer to the display screen assembly 2.

[0057] Preferably, one end of the first arc segment 312A is tangent to the straight line segment 311 to achieve a smooth connection, and the center of curvature of the first arc segment 312A is below the first arc segment 312A, that is, the first arc segment 312A is slightly convex, and the center of curvature of the second arc segment 312B is above the second arc segment 312B, that is, the second arc segment 312B is concave, so that the first arc segment 312A and the second arc segment 312B can be smoothly connected, which can prevent the driving mechanism 32 from jumping when moving along the first guide rail 31, thereby ensuring the smooth operation of the display screen assembly 2.

[0058] In some embodiments, based on the aforementioned solution, the length of the straight segment 311 is proportional to the width of the second display screen 22. Thus, the length of the straight segment 311 can be designed accordingly based on the width of the second display screen 22. Preferably, the length of the straight segment 311 is designed to preserve the shortest linear motion distance required to push the second display screen 22 out of the housing 1. This reduces the overall space required for the flip meter and provides a better user experience.

[0059] In some embodiments, the drive mechanism 32 includes a drive motor 321 fixedly connected to the second display screen 22 and a gear 322 connected to the output shaft of the drive motor 321. The straight segment 311 and the arc segment 312 of the first guide rail 31 are configured as guide racks that mesh with the gear 322. Preferably, the drive motor 321 is a constant-speed motor to drive the gear 322 to move at a constant speed along the first guide rail 31, thereby ensuring that the display screen assembly 2 remains stable during movement.

[0060] Specifically, a PCB board 15 is also provided in the shell 1. One end of the drive motor 321 is fixed to the PCB board 15 through a wire and is thus fixedly connected to the second display screen 22. The other end of the drive motor 321 is provided with an output shaft, and a gear 322 is provided on the output shaft. The gear 322 is engaged with the guide rack. Through the meshing action of the gear 322 and the rack, the gear 322 can move along the straight segment 311 and the arc segment 312 of the rack under the drive of the drive motor 321, thereby driving the display screen assembly 2 to perform linear motion and rotational motion.

[0061] In some embodiments, the continuous straight line segment 311, the first arc segment 312A, and the second arc segment 312B on the first guide rail 31 are each configured as a guide rack, with the endpoints of each segment smoothly connected. Preferably, the radius of the first arc segment 312A is greater than or equal to the radius of the gear 322, thereby further ensuring that the gear 322 does not bounce when moving on the guide rack, allowing the gear 322 to operate smoothly and the second display screen 22 to be smoothly ejected from the housing, resulting in a good user experience.

[0062] In some embodiments, the rotation limit assembly 4 includes a second guide rail 41 and a rocker arm 42, the second guide rail 41 is arranged on one side of the second display screen 22, one end of the rocker arm 42 is fixed to the shell 1 to form the rotation center 421, and the other end of the rocker arm 42 slides with the second guide rail 41; when the second display screen 22 rotates, one end of the rocker arm 42 is fixed as the rotation center 421, and the other end and the second guide rail 41 are rotated and limited to a preset position under the drive of the second display screen 22.

[0063] In some embodiments, two second guide rails 41 are provided, and each second guide rail 41 is installed on the back of the second display screen 22 along the width edge of the second display screen 22; two rocker arms 42 are also provided, and one end of each rocker arm 42 is fixed to the upper cover plate 14 of the shell 1, and a through hole 422 is opened at the end, and a support shaft 423 is used to connect the through holes 422 of the two rocker arms 42 from the back of the two display screens, so that during the movement of the second display screen 22, the support shaft 423 in the through hole 422 at one end of the rocker arm 42 is used as the fixed rotation center 421, and the other end of the rocker arm 42 is limited to a preset position as the second display screen 22 rotates, for example, it moves to the display position or horizontal position of the second display screen 22.

[0064] Specifically, during the process of the second display screen 22 making a linear motion along the straight section 311 of the first guide rail 31, the rocker arm 42 remains stationary, and the second guide rail 41 slides along the rocker arm 42 to follow the linear motion of the display screen assembly 2. During the sliding of the second guide rail 41, the other end of the rocker arm 42 slides from the first limit position of the second guide rail 41 close to the first display screen 21 to the middle position of the second guide rail 41, and the distance between the first limit position and the middle position is the distance of the straight section 311; when the display screen assembly 2 makes a rotational motion around the rotation center 421, one end of the rocker arm 42 is fixed to the upper cover 14, and the other end rotates with the second display screen 22 by a preset angle until the second display screen 22 rotates to the display position. During this process, the other end of the rocker arm 42 slides from the middle position of the second guide rail 41 to the second limit position of the second guide rail 42.

[0065] 7 , which shows a schematic diagram of the motion trajectory of the second display screen 22 in an embodiment of the present application.

[0066] As shown in Figure 7, when switching from the small-screen working state to the large-screen working state, the motion trajectory of the second display screen 22 is: straight line segment 311CD→first arc segment 312ABC→second arc segment 312BAB, that is, linear motion→rotational motion→rotational motion; conversely, when switching from the large-screen working state to the small-screen working state, the motion trajectory of the second display screen 22 is: second arc segment 312BAB→first arc segment 312ABC→straight line segment 311CD, that is, rotational motion→rotational motion→linear motion; wherein, the rotation center 421 is point F, point F is the center of curvature of the second arc segment 312BAB, the first limit position and the second limit position of the other end of the rocker arm 42 are points E and G respectively, ∠AFB=∠GFE, that is, the internal rotation angle of the rocker arm 42 and the second display screen 22 are kept consistent; the curvature center of the first arc segment 312ABC is point O, and point O is determined by the chamfered corners of the arc segment 312AB and the straight line segment 311DC.

[0067] In some embodiments, in order to minimize the space occupied by the second display screen 22 in the Z-axis direction during the rotational movement, the rotation angle of the second display screen 22 in the second arc segment 312B is 90 degrees, which overcomes the technical defect of the existing instrument display screen in the small-screen working state, that is, the large hollowing out at the bottom of the second display screen 22, making the overall structure of the instrument more beautiful.

[0068] In some embodiments, the other end of the rocker arm 42 remains consistent with the rotation angle of the second display screen 22 in the second arc segment 312B during the process of following the rotation of the second display screen 22. For example, when the rotation angle of the second display screen 22 in the second arc segment 312B is 90 degrees, the rotation angle of the other end of the rocker arm 42 is also 90 degrees, thereby ensuring that when the second display screen 22 rotates to a preset position, the rocker arm 42 can just provide support force for the second display screen 22 at the preset position.

[0069] In some embodiments, when the other end of the swing arm 42 rotates to a predetermined position, the display screen support point of the display screen assembly 2 is aligned horizontally with the rotation center 421, thereby improving structural stability. Preferably, the length of the swing arm 42 is set to minimize the space behind the display screen assembly 2; preferably, the rotation center 421 is located on the bisector of the angle between the first display screen 21 and the second display screen 22, thereby further ensuring structural stability.

[0070] Please refer to Figures 8 to 15, Figure 8 shows a schematic diagram of the self-locking position of the gear 322 in the working state of the first display screen 21 in the embodiment of the present application; Figure 9 shows a partial enlarged view of H in Figure 8; Figure 10 shows a schematic diagram of the locking position of the rocker arm 42 in the working state of the first display screen 21 in the embodiment of the present application; Figure 11 shows a partial enlarged view of I in Figure 10; Figure 12 shows a schematic diagram of the self-locking position of the gear 322 in the working state of the second display screen 22 in the embodiment of the present application; Figure 13 shows a partial enlarged view of J in Figure 12; Figure 14 shows a schematic diagram of the locking position of the rocker arm 42 in the working state of the second display screen 22 in the embodiment of the present application; Figure 15 shows a partial enlarged view of K in Figure 14.

[0071] In some embodiments, when the second display screen 22 is rotated and limited to a preset position around the rotation center 421 of the rotation limit assembly 4, the gear 322 is powered off and self-locked, that is, after the gear 322 is powered off, the gear 322 engages with the rack, so that when the second display screen 22 moves to the preset position, hard limiting can be avoided, and the second display screen 22 is firmly locked in the preset position to avoid shaking and abnormal noise.

[0072] In some embodiments, when the second display screen 22 is rotated and limited to a preset position around the rotation center 421 of the rotation limit assembly 4, the other end of the rocker arm 42 is clamped and limited to the end of the second guide rail 41, that is, the rocker arm 42 and the second guide rail 41 are structurally designed to achieve the limit locking of the rocker arm 42, so that when the second display screen 22 moves to the preset position, hard limitation can be avoided, and the second display screen 22 is firmly locked in the preset position, which can avoid shaking and abnormal noise.

[0073] As shown in Figures 8-15, when in the small-screen operating state, the gear 322 is powered off and self-locked at the starting position of the first guide rail 31. The other end of the rocker arm 42 is locked and limited at the starting end of the second guide rail 41 near the first display screen 21. The second display screen 22 is stored in the housing 1. At this time, the display screen assembly 2 is in the first limit position, and the first display screen 21 is in the preset position. When in the large-screen operating state, the gear 322 is powered off and self-locked at the end position of the first guide rail 31. The other end of the rocker arm 42 is locked and limited at the end of the second guide rail 41 away from the horizontal position of the second display screen 22. The first display screen 21 is stored in the housing 1. At this time, the display screen assembly 2 is in the second limit position, and the second display screen 22 is in the preset position.

[0074] Based on the above disclosure, the present application connects the first display screen 21 and the second display screen 22 to form a bent structure, and provides a first guide rail 31 including a continuous straight segment 311 and an arc segment 312, and a drive mechanism 32 fixedly connected to the second display screen 22. When the drive mechanism 32 moves along the straight segment 311 and the arc segment 312 of the first guide rail 31, it drives the display screen assembly 2 to rotate around the rotation center 421 of the rotation limit assembly 4 between the first limit position and the second limit position. When the display screen assembly 2 is in the first limit position, the first display screen 21 is in a preset position. When the display screen assembly 2 is in the second limit position, the second display screen 22 is in a preset position, thereby achieving multi-dimensional switching between the first display screen 21 and the second display screen 22, improving the sense of ritual and comfort of display screen switching, and enhancing the user experience. In addition, by providing the first arc segment 312A to achieve a smooth connection between the straight segment 311 and the second arc segment 312B, it prevents the gear 322 from jumping during movement, which affects the user experience. In addition, when the second display screen 22 performs linear motion and rotational motion, the opening of the display screen is smaller, that is, the distance of movement in the Z-axis direction is smaller, so when switching to the small-screen working state, the bottom hollow of the second display screen 22 is smaller, making the structure more beautiful.
