Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once a certain item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0064] See also Figures 1 to 4 As shown, according to an embodiment of the present application, a terminal device is provided, which may be, for example, an image processing terminal and a display terminal of an endoscope, or an image processing terminal and a display terminal of other medical equipment.

[0065] In this embodiment, the terminal device includes a terminal main body 10 and a handle 20. An installation part 11 is provided on the outer surface of the terminal main body 10; the end of the handle 20 is rotatably connected to the installation part 11. Among them, the handle 20 has a first position where it rotates around the installation part 11 and fits against the outer surface of the terminal main body 10 (see Figure 2 shown) and a second position where it rotates around the installation part 11 and forms a predetermined angle with the terminal main body 10 (see Figure 4 shown). When the handle 20 fits against the outer surface of the terminal main body 10, the handle 20 protrudes from the bottom end of the terminal main body 10.

[0066] When actually using the terminal device in this embodiment, by rotating the handle 20 to fit against the outer surface of the terminal main body 10 and being in the first position, the occupied space of the terminal device can be reduced. At this time, the handle 20 protrudes from the bottom end of the terminal main body 10, which is convenient for the user to hold the handle 20. By holding the handle 20, it is convenient to store and carry the terminal device; by rotating the handle 20 to form a predetermined angle with the terminal main body 10, at this time, through the action of the handle 20, the terminal main body 10 can be supported, which is convenient to stably place the terminal device on a predetermined tabletop or desktop. That is to say, in this embodiment, by providing a rotatable handle 20 and enabling the handle 20 to have a first position and a second position, when in use, the handle 20 not only facilitates the user to carry the terminal device but also can play a role in supporting the terminal device.

[0067] Compared with the prior art, the terminal device in this embodiment can simultaneously play the roles of facilitating carrying and supporting the terminal main body 10 only through the handle 20, without additionally setting up a bracket structure to support the terminal main body 10. The number of components is relatively small, the occupied space of the terminal device can be reduced, the structure is simple, and it is convenient to carry and use.

[0068] Specifically, the terminal main body 10 in this embodiment is generally in a cuboid structure. Structures such as a control main board and a display screen are provided on the terminal main body 10. The control main board is arranged inside the terminal main body 10, and the display screen is located on the front of the terminal main body 10. The handle 20 is rotatably connected to the back of the terminal main body 10. When the handle 20 is switched to the second position, it is convenient to support the terminal main body 10.

[0069] Furthermore, a groove 13 is provided on the terminal main body 10 in this embodiment. The installation part 11 is an installation cavity located at the end of the groove 13. When the handle 20 rotates around the installation part 11 to the first position, at least part of the handle 20 is located inside the groove 13. Such a setting can further reduce the volume of the terminal device and the occupied space of the terminal device.

[0070] In this embodiment, a limiting portion 12 is also provided on the terminal body 10, and the limiting portion 12 is provided on the side of the mounting portion 11 to limit the maximum rotation angle of the handle 20 relative to the terminal body 10, so as to prevent the handle 20 from rotating too much relative to the terminal body 10 and making it inconvenient to support the terminal body 10, and to a certain extent prevent the terminal body 10 from tipping over. Exemplarily, the limiting portion 12 can be a limiting surface, a limiting protrusion or a limiting block provided on the side of the mounting portion 11, and any other deformation methods under the conception of the present application are within the protection scope of the present application.

[0071] See also Figures 3 to 8 As shown, the terminal device in the present application further includes a locking assembly 30, which is disposed on the terminal body 10 to at least lock the handle 20 in the first position.

[0072] like Figures 3 to 6 ,as well as Figure 9 As shown, the terminal body 10 includes a shell 14, which is surrounded by a receiving cavity 141, the mounting portion 11 is located outside the shell 14, a through hole (not shown in the figure) is provided on the shell 14, and a locking groove 21 is provided on the handle 20. The locking assembly 30 includes a locking member 31, a first elastic element 32 and a toggle portion 33. During actual installation, the locking member 31 is slidably arranged in the receiving cavity 141, and the locking member 31 slides along the axial direction of the through hole to drive the end of the locking member 31 to pass through the through hole and be matched with the locking groove 21; the first elastic element 32 is arranged in the receiving cavity 141 and abuts against the side of the locking member 31 away from the through hole; the toggle portion 33 is arranged outside the shell 14 and passes through the shell 14 to be connected with the locking member 31, and the toggle portion 33 is used to drive the locking groove 21 to slide along the axial direction of the through hole under the action of external force.

[0073] When in use, a force is applied to the toggle portion 33, so that the toggle portion 33 drives the locking piece 31 to overcome the resisting force of the first elastic element 32 and move in a direction away from the handle 20. At this time, the locking piece 31 is disengaged from the locking groove 21, and the handle 20 can rotate relative to the mounting portion 11; when the force applied to the toggle portion 33 is removed, the locking piece 31 can move in a direction close to the handle 20 under the elastic force of the first elastic element 32 to cooperate with the locking groove 21 on the handle 20 to lock the handle 20 in the first position, thereby making it convenient to carry the terminal device.

[0074] For example, the locking member 31 in this embodiment is a long strip-shaped part, and a limiting groove 311 is provided on the locking member 31. The first elastic element 32 can be a spring, an elastic column or an elastic pad, and one end of the first elastic element 32 is installed in the limiting groove 311, and the structure is stable and reliable. The toggle part 33 includes a toggle block, and the toggle block is provided with a concave-convex texture to facilitate the user to operate the toggle block. The toggle block and the locking member 31 can be connected by through-hole buckle, bonding, welding or hole-column interference fit.

[0075] like Figure 7 As shown, in other embodiments of the present application, the locking component 30 can also be configured as a magnetic component 34, and the magnetic component 34 includes a magnetic component and a magnetic auxiliary component, one of which is disposed on the handle 20, and the other is disposed on the terminal body 10. Through the relative attraction between the magnetic component and the magnetic auxiliary component, the handle 20 is conveniently locked in the first position. Figure 7 FIG. 2 shows a situation where the magnetic attraction member is arranged on the handle 20 .

[0076] Exemplarily, one of the magnetic attraction component and the magnetic attraction auxiliary component in this embodiment is a magnet, and the other is a magnet or a structural component that can be attracted by a magnet, such as a structural component of iron, steel or nickel. During actual installation, the magnetic attraction component and the magnetic attraction auxiliary component can be fixed to the terminal body 10 or the handle 20 by means of screws 80, bolts, welding, clamping, etc. Of course, in other embodiments of the present application, the magnetic attraction component and the magnetic attraction auxiliary component can also be integrally formed with the terminal body 10 or the handle 20, respectively. As long as it is other deformation methods under the conception of the present application, they are all within the protection scope of the present application.

[0077] In other embodiments of the present application, the locking assembly 30 may also be a locking buckle or other structure.

[0078] Combination Figures 9 to 17 As shown, the handle 20 in this embodiment is rotatably connected to the mounting portion 11 via a hinge portion 40. A damping component 50 is provided between the hinge portion 40 and the handle 20. The provision of the damping component 50 facilitates providing damping between the hinge portion 40 and the handle 20. Thus, when the handle 20 is used to support the terminal body 10, it is convenient to limit the handle 20 to different rotation angles (angles at which the handle 20 rotates relative to the terminal body 10).

[0079] Combination Figures 9 to 12As shown, in some embodiments, the hinge portion 40 is fixedly installed inside the terminal body 10. The end of the handle 20 is provided with a hinge rotating shaft 60. The hinge rotating shaft 60 penetrates into the inside of the terminal body 10 and is rotatably connected to the hinge portion 40. The damping member 50 is disposed between the hinge portion 40 and the hinge rotating shaft 60. Specifically, the hinge portion 40 includes a hinge frame 41. A connection hole 412 (see the position marked in Figure 14 for the position marked) for the hinge rotating shaft 60 to pass through is provided on the hinge frame 41. During actual installation, the hinge rotating shaft 60 passes through the installation through hole 142 and is connected to the hinge frame 41. The damping member 50 includes a damping adjustment piece 51 and a locking nut 52. Among them, the damping adjustment piece 51 includes at least one piece. The damping adjustment piece 51 is located inside the terminal body 10. The damping adjustment piece 51 is sleeved on the hinge rotating shaft 60 and abuts against the surface of the hinge frame 41 facing away from the handle 20. The locking nut 52 is located inside the terminal body 10 and is sleeved on one end of the hinge rotating shaft 60 away from the handle 20 to lock the damping adjustment piece 51 between the hinge frame 41 and the hinge rotating shaft 60. Optionally, the damping adjustment piece 51 in this embodiment is a sheet-like structure with a certain elasticity. The damping adjustment piece 51 can be set to one piece, two pieces, three pieces, four pieces, five pieces or more than five pieces. During actual use, by screwing the locking nut 52, the friction force between the damping adjustment piece 51 and the hinge frame 41 can be adjusted. In this embodiment, the handle 20 is fixedly connected to the hinge rotating shaft 60. The hinge frame 41 is fixed inside the terminal body 10 by means of screws, pins or welding, etc. The hinge rotating shaft 60 penetrates from the outside of the terminal body 10 and is rotatably connected to the connection hole 412 of the hinge frame 41. When the handle 20 rotates under an external action, the hinge rotating shaft 60 rotates relative to the hinge frame 41 against the damping of the damping member 50. When the external force applied to the handle 20 is withdrawn, the handle 20 can be limited to the current rotation angle through the action of the damping member 50, which is convenient for supporting the terminal body 10.

[0080] In this embodiment, when the handle 20 drives the hinge rotating shaft 60 to rotate, it is necessary to overcome the friction force between the damping adjustment pieces 51. Then, after the handle 20 is stressed, it can rotate only when a certain torque is reached. This characteristic makes the torque value play a role in preventing the terminal body 10 from flipping when the terminal body 10 is in the first position; during the normal use of the terminal body 10, it can prevent or reduce the flipping of the terminal body 10.

[0081] See Figure 13As shown, in some embodiments of the present application, the hinge portion 40 further includes a hinge shaft fixed to the installation cavity. The damping member 50 includes an interference-fitted insertion hole and an insertion post. One of the ends of the hinge shaft and the hinge rotating shaft 60 is provided with an insertion hole (not shown in the figure), and the other end is provided with an insertion post (not shown in the figure), and the insertion post can rotate relative to the insertion hole under the action of an external force. In this embodiment, by setting the damping member 50 as an interference-fitted insertion hole and an insertion post, the structure is simple and easy to implement. When the handle 20 drives the hinge shaft to rotate, there is a certain frictional force between the insertion post and the insertion hole, which can provide a rotational torque for the handle 20 and facilitate limiting the handle 20 at a predetermined rotation angle.

[0082] See Figure 14 As shown, in some embodiments of this embodiment, the hinge portion 40 includes a hinge bracket 41, and a limiting hole 411 is provided on the hinge bracket 41; the damping member 50 further includes a damping ring 55 fixedly sleeved on the hinge rotating shaft 60. A wedge-shaped protrusion 551 is provided on one side of the damping ring 55 close to the hinge bracket 41. When the damping ring 55 rotates with the hinge rotating shaft 60, the wedge-shaped protrusion 551 deviates from the limiting hole 411 and abuts against the hinge bracket 41 or inserts into the limiting hole 411; wherein, when the wedge-shaped protrusion 551 inserts into the limiting hole 411, the handle 20 is in the first position; when the wedge-shaped protrusion 551 completely or partially disengages from the limiting hole 411, the handle 20 is in the second position. During use, when a force is applied to the handle 20 to make the handle 20 rotate, it can drive the damping ring 55 to rotate synchronously, and make the wedge-shaped protrusion 551 on the damping ring 55 abut against the hinge bracket 41 or insert into the limiting hole 411, thereby facilitating locking the handle 20 at a predetermined rotation angle.

[0083] During actual use, when the handle 20 is in the second position, the wedge-shaped protrusion 551 on the damping ring 55 cooperates with the flat wall of the hinge bracket 41. After the handle 20 gradually reaches the first position, the wedge-shaped protrusion 551 snaps into the limiting hole 411 of the hinge bracket 41. If you want to make the handle 20 disengage from the first position, an external force can be applied to the handle 20 to make the wedge-shaped protrusion 551 gradually climb the slope, disengage from the limiting hole 411 and abut against the hinge bracket 41, which is convenient for supporting the terminal body 10.

[0084] Exemplarily, the limiting hole 411 and the wedge-shaped protrusion 551 in this embodiment can be one, or two or more than three. The case where the limiting hole 411 and the wedge-shaped protrusion 551 are two is shown in the present application.

[0085] See 15 and Figure 17As shown, the hinge portion 40 includes a hinge frame 41. The damping member 50 further includes a fixed wheel disc 58, a rotating wheel disc 56, and an elastic member 57. The fixed wheel disc 58 is fixedly connected to the hinge frame 41. A first annular rack 581 is provided on the first side of the fixed wheel disc 58. The rotating wheel disc 56 is movably sleeved on the hinge rotating shaft 60 and rotates synchronously with the hinge rotating shaft 60. A second annular rack 561 meshing with the first annular rack 581 is provided on the rotating wheel disc 56. The elastic member 57 includes a second locking member 571 and an elastic assembly 572. Both the elastic assembly 572 and the second locking member 571 are sleeved on the hinge rotating shaft 60, and the opposite ends of the elastic assembly 572 respectively abut against the rotating wheel disc 56 and the second locking member 571.

[0086] During actual use, an external force is applied to the handle 20. This external force can overcome the meshing force between the first annular rack 581 and the second annular rack 561 and the force exerted on the rotating wheel disc 56 by the elastic member 57. After the handle 20 is rotated to the required angle, the external force applied to the handle 20 is withdrawn. The elastic assembly 572 resets, can tightly abut the rotating wheel disc 56 against the fixed wheel disc 58, and makes the first annular rack 581 mesh with the second annular rack 561, thereby locking the handle 20 at the current rotation angle.

[0087] Exemplarily, the elastic assembly 572 in this embodiment includes a spring (as Figure 15 shown), a metal elastic pad, a polymer elastic sheet (as Figure 16 and Figure 17 shown) and at least one of them; further, the second locking member 571 includes a locking screw, with a simple structure and being easy to implement.

[0088] Referring to Figure 18 and Figure 19 shown, a damping pad 70 is provided on the side of the terminal body 10 and / or the handle 20 in this embodiment. That is to say, the damping pad 70 is provided on at least one of the terminal body 10 and the handle 20. With such a setting, when the terminal device is placed on a desktop or a tabletop, it is not easy to tip over, facilitating the use by medical staff.

[0092] The terminal device of this application can solve the following technical problems: First, the problem of the flip of the hand-held device; Second, when the device is placed flat on the desktop, how the device maintains its position without tipping at different angles.

[0093] In this application, by installing a handle on the outer side of the housing of the terminal body, the handle can rotate around the terminal body. When the handle is in the zero position, that is, the first position described above, the handle protrudes beyond the contour of the terminal body, facilitating the insertion and lifting of fingers; when the device is in the working position, that is, the second position described above, the end of the handle supports on the desktop to prevent the device from tipping.

[0094] In addition, a damping component is provided between the handle and the hinge part of this application. This damping component can provide a predetermined torque for the rotation of the handle, facilitating the handle to be limited at a certain rotation angle, facilitating the stable support of the terminal body, and effectively preventing the terminal body from tipping during use. The structure is simple and convenient to use.

[0095] For the sake of convenience in description, spatial relative terms such as "above...", "over...", "on the upper surface of...", "upper" etc. can be used here to describe the spatial position relationship between a device or feature shown in the figure and other devices or features. It should be understood that spatial relative terms are intended to include different orientations during use or operation in addition to the orientation described in the figure for the device. For example, if the device in the figure is inverted, the device described as "above other devices or structures" or "over other devices or structures" will be positioned as "below other devices or structures" or "under other devices or structures" afterwards. Thus, the exemplary term "above..." can include both the orientations of "above..." and "below...". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations are made for the spatial relative descriptions used here.

[0096] In addition, it should be noted that using words such as "first", "second", etc. to limit components is only for the convenience of distinguishing the corresponding components.
