[0018] 2.

DETAILED DESCRIPTION

[0032] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0033] Reference Figure 1-Figure 4 A combined intelligent electronic table card, comprising a mounting base 1, a display screen 2 and a control mechanism 3; a lifting mounting frame 11 is arranged on the mounting base 1; a first horizontal plate 111, a second horizontal plate 112 and a third horizontal plate 113 are arranged on the mounting frame 11, and a first guide bar 1111 and a second guide bar 1121 are respectively arranged on the side of the first horizontal plate 111 and the second horizontal plate 112 away from the mounting base 1; a fixing plate 12 is fixedly installed on the mounting base 1, and an elastic member is arranged on the fixing plate 12, and two ends of the elastic member are respectively connected to the fixing plate 12 and the third horizontal plate 113, and a connecting rod 122 for electrically connecting to the display screen 2 is arranged on the fixing plate 12; a back plate 21 is arranged on the display screen 2, and a slot for plugging and cooperating with the connecting rod 122 is opened on the back plate 21; the control mechanism 3 is used to limit the separation of the back plate 21 from the mounting base 1.

[0034] The present invention realizes the function of controlling the precise matching of the connecting rod 122 and the slot when installing the electronic table card through the mounting seat 1, the mounting frame 11, the fixing plate 12, the display screen 2 and the back plate 21, so as to achieve the effect of making the display screen 2 and the mounting seat 1 stably matched. When the display screen 2 is installed on the desktop, it can avoid the situation that the connection is damaged due to excessive docking deviation. At the same time, when the operator installs the display screen 2, the first guide bar 1111 and the second guide bar 1121 on the first horizontal plate 111 and the second horizontal plate 112 are used for guidance, so that the back plate 21 of the display screen 2 can be quickly and accurately docked with the mounting frame 11, thereby improving the portability and accuracy of the installation, and solving the problem that the wear of the connection of the traditional electronic table card during the installation process is uncontrollable. The display screen 2 is preferably an electronic ink screen, which consumes a small amount of electricity only when the information is updated, and the display effect is still clear under strong light, and does not need to be continuously powered to maintain brightness like the traditional LCD screen 2, which conforms to the modern environmental protection concept. A power source is provided in the back plate 21 of the display screen 2. When the back plate 21 of the display screen 2 is separated from the connecting rod 122, the display screen 2 can still operate at low power. The first elastic member 121 is preferably a compression spring with a hydraulic damping rod.

[0035] In the working state, when the operator needs to remove the display screen 2, the display screen 2 is first slid upward, and then the thrust provided by the operator overcomes the elastic force of the first elastic member 121, so that the display screen 2 and the back plate 21 push the mounting frame 11 upward until the connecting rod 122 is completely separated from the slot on the back plate 21, and the electrical connection between the display screen 2 and the connecting rod 122 is disconnected. Then the operator releases the separation restriction of the back plate 21 by the control mechanism 3, and removes the back plate 21 from the mounting frame 11.

[0036] After the display screen 2 is used, the operator first lifts the mounting frame 11, and the first elastic member 121 is compressed during the movement of the mounting frame 11. Then, the push plate 42 of the display screen 2 is pushed onto the mounting frame 11, and guided by the first guide bar 1111 and the second guide bar 1121 on the first transverse plate 111 and the second transverse plate 112, the mounting frame 11 and the display screen 2 are stably docked.

[0037] After completing the docking action, the operator releases the display screen 2, and the third horizontal plate 113 of the mounting frame 11 is pulled by the elastic force of the first elastic member 121, so that the mounting frame 11 moves downward, and the display screen 2 and the back plate 21 move under the thrust provided by the mounting frame 11 and their own gravity. In the process of movement, the movement of the mounting frame 11 is guided by the sliding cooperation between the mounting seat 1 and the mounting frame 11, so that the back plate 21 of the display screen 2 can be accurately docked with the connecting rod 122. In addition, during the docking process, the downward movement speed of the display screen 2 is controlled by the damping rod of the first elastic member 121 to avoid a violent collision between the back plate 21 and the connecting rod 122. In the docking process, there is no need for manual control by the operator, which further avoids the insertion of the back plate 21 and the connecting rod 122 from being interfered by external forces, thereby improving the stability of the docking.

[0038] Reference Figure 2 , Figure 5 and Figure 6 : The control mechanism 3 includes a first limiting component 31, a second limiting component 32 and a control component 33; the first limiting component 31 is used to limit the sliding path of the back plate 21 along the mounting seat 1; the second limiting component 32 is used to limit the movement of the mounting frame 11; the first limiting component 31 and the second limiting component 32 are both transmission-connected with the control component 33; in the working state, when the first limiting component 31 limits the movement of the back plate 21, the control component 33 cancels the movement restriction of the mounting frame 11 by the second limiting component 32; when the second limiting component 32 limits the movement of the mounting frame 11, the control component 33 cancels the movement restriction of the back plate 21 by the first limiting component 31.

[0039] When the back plate 21 is docked with the mounting frame 11, the movement of the back plate 21 and the mounting frame 11 is controlled and guided by the first limiting component 31, the second limiting component 32 and the control component 33 to ensure that the connecting rod 122 on the fixing plate 12 can be aligned with the slot of the back plate 21 when the display screen 2 is installed. When removing the display screen 2, the operator lifts the display screen 2 upward, and the display screen 2 and the back plate 21 drive the mounting frame 11 to move upward, and the first elastic member 121 contracts under the thrust. When the display screen 2 and the mounting frame 11 move to the specified position, the operator releases the movement restriction of the back plate 21 by the first limiting component 31 through the control component 33, and then removes the back plate 21 from the mounting seat 1. After the use of the display screen 2 is completed, the display screen 2 is installed on the mounting seat 1. The operator pushes the back panel 21 of the display screen 2 onto the mounting frame 11 through the guidance of the first guide bar 1111 and the second guide bar 1121, and the upper and lower sides of the back panel 21 are respectively in contact with the first transverse plate 111 and the second transverse plate 112. After the mounting frame 11 and the back panel 21 are docked, the first limiting component 31 limits the movement path of the back panel 21, so that the back panel 21 can only be raised and lowered on the mounting seat 1 along with the mounting frame 11. At this time, the control component 33 releases the movement restriction of the mounting frame 11 by the second limiting component 32, and the third transverse plate 113 on the mounting frame 11 moves downward under the elastic force of the first elastic member 121. The slot of the back panel 21 is close to the connecting rod 122, so that the connecting rod 122 is plugged into and matched with the slot of the back panel 21.

[0040] Reference Figure 4 , Figure 5 and Figure 7 : The first limiting component 31 includes a lateral clamping strip 311 and a second elastic member 312; two lateral clamping strips 311 are provided, and the two lateral clamping strips 311 are respectively slidably arranged on both sides of the mounting base 1; at least two second elastic members 312 are provided, and the two second elastic members 312 are respectively arranged on the two lateral clamping strips 311; the two ends of the second elastic member 312 are respectively connected to the lateral clamping strip 311 and the mounting base 1; a side plate 22 is respectively provided on both sides of the back plate 21 close to the two lateral clamping strips 311, and a first straight groove 221 is opened on the side plate 22. When the lateral clamping strip 311 is slidably matched with the first straight groove 221, the lateral clamping strip 311 limits the moving path of the back plate 21 and the side plate 22.

[0041] The present invention realizes the function of limiting the moving direction of the back plate 21 when the back plate 21 is docked with the mounting frame 11 through the lateral clamping strip 311, the second elastic member 312, the side plate 22 and the first straight groove 221. A slope is provided on one side of the lateral clamping strip 311. When the display screen 2 is installed, the operator pushes the back plate 21 of the display screen 2 into the mounting frame 11. When the side plate 22 on the back plate 21 contacts the slope of the lateral clamping strip 311, the side plate 22 squeezes the slope of the lateral clamping strip 311, and the second elastic member 312 shrinks under the squeezing action. When the first straight groove 221 on the side plate 22 is aligned with the lateral clamping strip 311, the lateral clamping strip 311 is clamped with the first straight groove 221 under the elastic force of the second elastic member 312, and the movement of the back plate 21 is guided by the sliding fit between the lateral clamping strip 311 and the first straight groove 221. When the mounting frame 11 and the back plate 21 move under the elastic force of the first elastic member 121 , the back plate 21 can be prevented from being deflected, so that the slot on the back plate 21 and the connecting rod 122 can be accurately plugged and matched.

[0042] Reference Figure 6 and Figure 7 : The second limiting component 32 includes a transverse clamping strip 321 and a third elastic member 322; the transverse clamping strip 321 is slidably installed on the mounting base 1; the two ends of the third elastic member 322 are respectively connected to the transverse clamping strip 321 and the mounting base 1; in the working state, when the back plate 21 of the display screen 2 abuts against the mounting base 1, the transverse clamping strip 321 is squeezed by the back plate 21 and is in a contracted state.

[0043] The present invention realizes the function of limiting the reset of the mounting frame 11 when the display screen 2 is removed by means of the transverse clamping strip 321 and the third elastic member 322. When removing the display screen 2, the operator first lifts the display screen 2 upwards, and pushes the mounting frame 11 upwards through the display screen 2 and the back plate 21. After the back plate 21 and the mounting frame 11 are moved to a specified height, the control component 33 is used to move the lateral clamping strip 311 in a direction away from the first straight groove 221, thereby realizing the separation of the lateral clamping strip 311 from the first straight groove 221, releasing the movement restriction of the back plate 21 by the first limiting component 31, and then the operator removes the display screen 2 from the mounting seat 1. During the separation process of the back plate 21 of the display screen 2 from the mounting seat 1, the transverse clamping strip 321 will still abut against the back plate 21 under the elastic force of the third elastic member 322. When the back panel 21 is separated from the transverse clamping strip 321, the transverse clamping strip 321 is in an extended state under the elastic force of the third elastic member 322, the first transverse plate 111 on the mounting frame 11 abuts against the transverse clamping strip 321, and at this time the first elastic member 121 is in a contracted state, the mounting frame 11 is subjected to the thrust applied by the first elastic member 121, and the transverse clamping strip 321 restricts the mounting frame 11 from resetting under the elastic force of the first elastic member 121.

[0044] Reference Figure 6-Figure 8: The control component 33 includes a support 331, an insertion rod 332 and a connecting frame 333; the support 331 is arranged on the lateral clamping strip 311, and a first oblique guide groove 3311 is opened on the support 331; the insertion rod 332 is slidably installed on the mounting seat 1, and the insertion rod 332 abuts against the first oblique guide groove 3311; the connecting frame 333 is connected to the insertion rod 332, and a fourth elastic member 3331 and a fifth elastic member 3332 are provided on the connecting frame 333, and the two ends of the fourth elastic member 3331 are respectively connected to the connecting frame 333 and the mounting seat 1, and the two ends of the fifth elastic member 3332 are respectively connected to the connecting frame 333 and the transverse clamping strip 321.

[0045] The present invention realizes the function of controlling the opening and closing of the first limiting component 31 and the second limiting component 32 through the support 331, the insertion rod 332 and the connecting frame 333. When disassembling the display screen 2, the operator moves the display screen 2 upward. After the display screen 2 is moved up to the specified height, the operator pushes the connecting frame 333, and the fifth elastic member 3332 contracts under the thrust, and the connecting frame 333 drives the insertion rod 332 to move, and the support 331 and the lateral clamping strip 311 are pushed to move by the squeezing effect of the insertion rod 332 on the first oblique guide groove 3311 on the support 331. When the lateral clamping strip 311 is separated from the first straight groove 221, the first limiting component 31 no longer limits the moving path of the back panel 21, and then the display screen 2 is removed. After the display screen 2 is removed, the operator no longer presses the connecting frame 333, and the connecting frame 333 is reset under the elastic force of the fourth elastic member 3331. The insertion rod 332 on the connecting frame 333 and the first oblique guide groove 3311 of the support 331 are squeezed, and the transverse clamping strip 321 is extended under the elastic force of the third elastic member 322, and the fifth elastic member 3332 is also in a naturally extended state under the elastic force. The support 331 and the lateral clamping strip 311 are separated from the first straight groove 221 under the squeezing action of the insertion rod 332.

[0046] When installing the display screen 2, the operator pushes the back panel 21 of the display screen 2 onto the mounting frame 11, and the lateral clamping strip 321 gradually shrinks under the squeezing action of the back panel 21. After the installation of the display screen 2 is completed, the lateral clamping strip 321 is in a contracted state, and the fifth elastic member 3332 transfers the thrust to the connecting frame 333 under the pushing action of the lateral clamping strip 321, and then uses the thrust to overcome the elastic force of the third elastic member 322 to push the connecting frame 333 to move, and the connecting frame 333 drives the insertion rod 332 to move, so that the insertion rod 332 no longer squeezes the first oblique guide groove 3311 on the support 331, and the lateral clamping strip 311 and the support 331 extend under the elastic force of the third elastic member 322, so that the first limiting component 31 can limit the moving direction of the back panel 21.

[0047] Reference Figure 5 and Fig. 9: The mounting seat 1 is provided with a reset mechanism 4 for controlling the upward movement of the mounting frame 11; the reset mechanism 4 includes a linear driver 41 and a push plate 42; the linear driver 41 is mounted on the mounting seat 1; the push plate 42 is transmission-connected to the driving end of the linear driver 41.

[0048] The present invention realizes the function of pushing the mounting frame 11 upward through the linear drive 41 and the push plate 42. When the display screen 2 is disassembled, the operator does not need to manually push the mounting frame 11 upward. The linear drive 41 is preferably an electric push rod, and a controller for human-computer interaction is provided on the mounting seat 1, and the linear drive 41 is electrically connected to the controller. When the display screen 2 is disassembled, the operator sends a signal to the linear drive 41 through the controller, and the linear drive 41 drives the push plate 42 to move upward. The push plate 42 contacts the third horizontal plate 113 on the mounting frame 11 and pushes the third horizontal plate 113. The mounting frame 11 moves upward under the action of the thrust, and then the back plate 21 of the display screen 2 is pushed to move through the second horizontal plate 112 on the mounting frame 11. When the mounting frame 11 moves to the specified height, the control component 33 releases the movement restriction of the back plate 21 by the first restriction component 31, and the display screen 2 is removed.

[0049] Reference Figure 5 and Fig. 9 : A second oblique guide groove 421 is provided on both sides of the push plate 42; in the process of the linear drive 41 driving the push plate 42 to move upward, when the second oblique guide groove 421 contacts the lateral card strip 311, the push plate 42 squeezes the lateral card strip 311 until the lateral card strip 311 is in a retracted state.

[0050] The present invention releases the movement restriction of the back plate 21 by the first restriction component 31 through the second oblique guide groove 421 when the reset mechanism 4 drives the mounting frame 11 to move upward. When disassembling the display screen 2, in addition to moving the display screen 2 upward, it is also necessary to release the movement restriction of the back plate 21 by the first restriction component 31. To this end, the second oblique guide groove 421 is provided on both sides of the push plate 42. In the process of the linear driver 41 driving the push plate 42 to move upward, the second oblique guide groove 421 of the push plate 42 applies an extrusion force to the lateral clamping strip 311, and then the extrusion force overcomes the elastic force of the second elastic member 312, so that the lateral clamping strip 311 is in a contracted state, and the movement restriction of the back plate 21 by the first restriction component 31 is released, so that the operator can smoothly remove the display screen 2 without manually pressing the connecting frame 333.

[0051] Reference Figure 6 and Fig.10: A slider 1122 is provided on the second horizontal plate 112; a second straight groove 114 is provided on the mounting frame 11, and the slider 1122 is slidably matched with the second straight groove 114; at least three positioning holes 1141 are provided on the second straight groove 114, and internal threads are provided in the positioning holes 1141, and the multiple positioning holes 1141 are equidistantly distributed along the extension direction of the second straight groove 114; a bolt 1123 is provided on the slider 1122, and the bolt 1123 is threadedly connected to the positioning hole 1141.

[0052] The present invention realizes the function of adjusting the distance between the first horizontal plate 111 and the second horizontal plate 112 through the slider 1122, the bolt 1123, the second straight groove 114 and the positioning hole 1141. When installing the display screen 2, the sizes of the display screen 2 may be different. In order to improve the adaptability of the mounting frame 11, a separate mounting frame 11 is provided. The second horizontal plate 112 can be removed from the mounting frame 11 by rotating the bolt 1123, and then the distance between the second horizontal plate 112 and the first horizontal plate 111 is adjusted, and then the second horizontal plate 112 is fixed to the mounting frame 11 by the bolt 1123, so that the mounting frame 11 can adapt to the back plate 21 of different widths.

[0053] Reference Figure 1 , Figure 6 and Fig.11 The electronic table card also includes a base 5, on which a fixed roller 51 is provided, on which a rotating shaft 511 is provided, and the mounting seat 1 is rotatably connected to the rotating shaft 511.

[0054] The present invention realizes the function of supporting the mounting seat 1 through the base 5 and the fixed roller 51. At the same time, the angle of the mounting seat 1 can be adjusted by rotating the mounting seat 1, and then the angle of the display screen 2 can be adjusted after the display screen 2 is installed, thereby improving the effect of the display screen 2 displaying information.

[0055] Reference Figure 1 , Figure 6 and Fig.11 The mounting seat 1 is provided with an elastic card strip 13; the fixed roller 51 is provided with a card slot 512 for engaging with the elastic card strip 13, and the card slot 512 is provided with at least two.

[0056] The present invention realizes the function of supporting the mounting seat 1 through the elastic clip 13 and the slot 512. After adjusting the angle of the mounting seat 1, the mounting seat 1 can be initially supported by the friction between the rotating shaft 511 and the mounting seat 1. However, as the number of rotations of the mounting seat 1 increases, the connection between the mounting seat 1 and the rotating shaft 511 will wear, thereby affecting the stability of the support for the mounting seat 1. When the mounting seat 1 is in an inclined state, it will deflect under the action of gravity. For this reason, an elastic clip 13 and a slot 512 are provided. When the mounting seat 1 is rotated, the angle of the mounting seat 1 is adjusted so that the elastic clip 13 on the mounting seat 1 is engaged with the nearest slot 512, and then the mounting seat 1 is supported by the cooperation of the elastic clip 13 and the slot 512 to maintain the inclination angle of the mounting seat 1.

[0057] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
