Description

Technical Field

[0001] The utility model relates to the technical field of displays, in particular to an angle-adjustable support arm structure and a display terminal. Background Art

[0002] Currently, in certain usage scenarios, such as some desktop medium-frequency physiotherapy devices, the display screens have a fixed viewing angle. This means that users must view the display from a specific angle to see the content clearly, especially when multiple people are viewing the device simultaneously or operating it from different positions. For example, a doctor treating a patient may need to view the device's display from different angles, but due to the limited viewing angle, the treatment information may not be clearly visible.

[0003] Furthermore, some displays may reflect light under certain lighting conditions, affecting the display quality. This is particularly noticeable in brightly lit environments, where it can make it difficult for users to see the displayed content. For example, in a room with direct sunlight or in a medical setting with strong lighting, reflections on the display can make it difficult for users to accurately read treatment parameters. Utility Model Content

The utility model provides an angle-adjustable support arm structure and a display terminal.

[0005] The technical solution of the utility model to solve the above technical problems is as follows:

[0006] On the one hand, the utility model provides an arm structure with adjustable angle, including arms at both ends respectively used to rotate and connect a host and a display screen group, and a rotating shaft assembly is installed at both ends of the arm, and the two rotating shaft assemblies each include a fixed part and a rotating part that can rotate relative to each other, and the fixed parts of the two rotating shaft assemblies are fixedly connected to the arm, and the rotating part of the rotating shaft assembly located at one end of the arm is used to be fixedly connected to the host, and the rotating part of the rotating shaft assembly located at the other end of the arm is used to be fixedly connected to the display screen group.

[0007] The beneficial effects of the present invention are as follows: when in use, the display screen group and the support arm are relatively rotated through the rotating shaft assembly located at the other end of the support arm to achieve any angle adjustment so that the user can observe and use from different angles, and the display screen group and the support arm are simultaneously relatively rotated relative to the main body through the rotating shaft assembly located at one end of the support arm to achieve the height adjustment of the display screen group so as to avoid the influence of light, thereby improving the technical problem that the angle of the display screen of the existing desktop medium-frequency physiotherapy device is fixed and cannot meet the user's technical problem of clearly reading treatment information from different angles under lighting conditions.

[0008] On the basis of the above technical solution, the present invention can also be improved as follows.

[0009] Furthermore, the two rotating shaft assemblies each include two coaxial straight rotating shafts, one end of each straight rotating shaft forms a fixed portion, and the other end forms a rotating portion, and the four straight rotating shafts form four rotating portions.

[0010] The beneficial effect of adopting the above-mentioned further solution is that when in use, the user applies force to the display screen group, causing the display screen group to rotate around the straight-line rotating shaft located at the other end of the support arm as the central axis, thereby changing the opening angle of the display screen group, and driving the display screen group and the support arm to rotate around the straight-line rotating shaft located at one end of the support arm as the central axis at the same time. When changing the height of the display screen group, the two ends of each straight-line rotating shaft rotate relative to each other.

[0013] Furthermore, the two No. 1 fixing members are both used to be installed inside the host, and the two No. 2 fixing members are both used to be installed inside the display screen group.

[0014] The beneficial effect of adopting the above further solution is that the No. 1 fixing member and the No. 2 fixing member are installed in a hidden and protective manner.

[0015] Furthermore, a No. 1 socket is provided on one side of each No. 1 fixing member, and the rotating parts of the two straight rotating shafts located at one end of the support arm are inserted into and detachably connected to the No. 1 socket.

[0016] The beneficial effect of adopting the above further scheme is: during installation, after the fixed part of the straight-line rotating shaft is fixedly connected to the support arm, the rotating part of the straight-line rotating shaft is inserted into the No. 1 socket of the corresponding No. 1 fixing part, thereby realizing the connection and installation of the straight-line rotating shaft and the corresponding No. 1 fixing part.

[0017] Furthermore, each of the second fixing members includes a hook portion detachably connected to the rotating portion of the corresponding straight shaft and a hanging portion fixedly connected to the hook portion, and the hanging portion is used to be installed on the display screen group.

[0018] The beneficial effect of adopting the above further solution is: during installation, the hanging part is first installed on the display screen group to achieve the fixed installation of the second fixing part, and then the straight-line shaft and the hook part are connected and installed.

[0019] On the other hand, the present invention provides a display terminal, comprising the above-mentioned angle-adjustable arm structure, a host and a display screen group, wherein both ends of the arm are rotatably connected to the host and the display screen group respectively through the two shaft assemblies.

[0020] The beneficial effect of adopting the above-mentioned further scheme is: by using a support arm to install the display screen group on the main unit, during use, the angle of the display screen group relative to the support arm can be changed through the rotating shaft assembly located at both ends of the support arm, and the angle between the support arm and the main unit can be changed, and the opening angle and use height of the display screen group can be adjusted to ensure that the user can clearly read the treatment information from various angles and under various lighting conditions.

[0047] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0048] On the one hand, the present invention provides an arm structure with adjustable angle, as described in detail below.

[0049] Example 1

[0050] like Figures 1 to 10 , an angle-adjustable arm structure, including arms 2 at both ends for rotationally connecting a host 1 and a display screen group 3, respectively. A rotating shaft assembly is installed at both ends of the arm 2, and both rotating shaft assemblies include a fixed portion and a rotating portion that can rotate relative to each other. The fixed portions of the two rotating shaft assemblies are fixedly connected to the arm 2, and the rotating portion of the rotating shaft assembly located at one end of the arm 2 is used to be fixedly connected to the host 1, and the rotating portion of the rotating shaft assembly located at the other end of the arm 2 is used to be fixedly connected to the display screen group 3.

[0051] The beneficial effects of this embodiment are: when in use, the display screen group 3 and the support arm 2 are relatively rotated through the shaft assembly located at the other end of the support arm 2 to achieve any angle adjustment, so that the user can observe and use it from different angles, and the display screen group 3 and the support arm 2 are simultaneously relatively rotated relative to the main unit 1 through the shaft assembly located at one end of the support arm 2 to achieve the height adjustment of the display screen group 3 to avoid the influence of light, thereby improving the technical problem that the angle of the display screen of the existing desktop medium-frequency physiotherapy device is fixed and cannot meet the user's technical problem of clearly reading treatment information from different angles under lighting conditions.

[0052] As a specific embodiment of the above embodiment, arm 2 is a plate-like structure, specifically a straight or curved plate. The middle end of arm 2 is a through-opening structure to reduce weight. Both ends of arm 2 have arc-shaped surfaces, which are coaxial with the adjacent rotating shaft assembly to ensure smooth rotation of arm 2 and display panel assembly 3.

[0053] Example 2

[0054] like Figures 3 to 10 On the basis of Example 1, the two rotating shaft assemblies each include two coaxial straight-line rotating shafts 4, one end of each straight-line rotating shaft 4 forms a fixed portion, and the other end forms a rotating portion, and the four straight-line rotating shafts 4 form four rotating portions.

[0055] The beneficial effect of adopting the preferred solution in the above embodiment is that when in use, the user applies force to the display screen group 3, causing the display screen group 3 to rotate around the straight-line rotating shaft 4 located at the other end of the support arm 2 as the central axis, so as to change the opening angle of the display screen group 3, and drive the display screen group 3 and the support arm 2 to rotate around the straight-line rotating shaft 4 located at one end of the support arm 2 as the central axis at the same time. When the height of the display screen group 3 is changed, the two ends of each straight-line rotating shaft 4 rotate relative to each other.

[0056] In the embodiment of the present invention, the straight shaft 4 can be purchased from the market and the relevant installation work can be carried out. Figure 12 and Figure 13 The straight-line rotating shaft 4 includes a matching male shaft 41 and a female shaft 42, which are connected by an intermediate bolt 43. When the male shaft 41 and the female shaft 42 are flipped, corresponding torque will be generated; wherein, the right end of the male shaft 41 is provided with an internal threaded hole for threaded connection of the intermediate bolt 43, and the side wall of the male shaft 41 is penetrated to form two opposite openings, which are both connected to the internal threaded hole; the head of the intermediate bolt 43 is installed in the mounting hole at the left end of the female shaft 42, and an inclined surface structure is formed at the connection between the head of the intermediate bolt 43 and the rod. Under the action of the inclined surface, the opening of the male shaft 41 is propped open, so that the male shaft 41 interferes with the female shaft 42. The rotation force of the entire straight-line rotating shaft 4 is controlled by adjusting the tightness of the intermediate bolt 43, so that the support arm 2 can rotate relative to the main machine 1 and stop at any angle of 0°-90°.

[0057] As a parallel solution, a damping plate is provided inside the rotating shaft so that the display screen group 3 can rotate relative to the support arm 2 and stop at any angle of 0°-90°, and the support arm 2 can rotate relative to the host 1 and stop at any angle of 0°-90°.

[0058] As one of the parallel solutions of this embodiment, both shaft assemblies include a straight shaft 4. The middle ends of the two straight shafts 4 form a fixed portion, and the ends form a rotating portion, forming four rotating portions. During use, the user applies force to the display assembly 3, causing the display assembly 3 to rotate around the straight shaft 4 located at the other end of the support arm 2, thereby changing the opening angle of the display assembly 3. This also causes the display assembly 3 and the support arm 2 to simultaneously rotate around the straight shaft 4 located at one end of the support arm 2. When changing the height of the display assembly 3, the middle ends of the two straight shafts 4 rotate relative to the ends.

[0059] As a second parallel solution of this embodiment, both shaft assemblies include a straight shaft 4, with one end of each shaft forming a fixed portion and the other end forming a rotating portion. During use, the user applies force to the display assembly 3, causing the display assembly 3 to rotate about the straight shaft 4 located at the other end of the support arm 2, thereby changing the opening angle of the display assembly 3. This also causes the display assembly 3 and the support arm 2 to rotate simultaneously about the straight shaft 4 located at one end of the support arm 2. When changing the height of the display assembly 3, one end of the two straight shafts 4 rotates relative to the other end.

[0060] Example 3

[0061] like Figures 3 to 10 On the basis of Examples 1 and 2, both rotating shaft assemblies further include two No. 1 fixing members 5 and two No. 2 fixing members 6. The two No. 1 fixing members 5 are both used to be installed on the host 1, and are respectively detachably connected to the rotating parts of the two straight rotating shafts 4 located at one end of the support arm 2. The two No. 2 fixing members 6 are both used to be installed on the display screen group 3, and are respectively detachably connected to the rotating parts of the two straight rotating shafts 4 located at the other end of the support arm 2.

[0062] The beneficial effect of adopting the preferred solution in the above embodiment is that the installation of the corresponding straight shaft 4 is achieved through the No. 1 fixing member 5 and the No. 2 fixing member 6.

[0063] As a parallel solution to the above embodiment, both rotating shaft assemblies further include four No. 1 fixing members 5 , which are mounted in pairs on the main unit 1 and the display panel assembly 3 . The four No. 1 fixing members 5 are detachably connected to the four rotating portions formed by the respective straight-line rotating shafts 4 . The four No. 1 fixing members 5 are used to respectively achieve the installation of the corresponding straight-line rotating shafts 4 .

[0064] As a second parallel solution to the above embodiment, both shaft assemblies further include four second fixing members 6 , which are mounted in pairs on the main unit 1 and the display panel assembly 3 . Each of the four second fixing members 6 is detachably connected to the four rotating portions formed by the respective straight shafts 4 . The four second fixing members 6 are used to securely mount the corresponding straight shafts 4 .

[0065] Example 4

[0066] like Figures 4 to 8 On the basis of Examples 1-3, the two No. 1 fixing members 5 are both used to be installed inside the host 1 , and the two No. 2 fixing members 6 are both used to be installed inside the display screen group 3 .

[0067] The beneficial effect of adopting the preferred solution in the above embodiment is that the No. 1 fixing member 5 and the No. 2 fixing member 6 are installed in a hidden and protective manner.

[0068] Example 5

[0069] like Figures 4 to 8 On the basis of embodiments 1-4, a No. 1 socket 51 is provided on one side of the No. 1 fixing member 5, and the rotating parts of the two straight shafts 4 located at one end of the support arm 2 are inserted into and detachably connected to the No. 1 socket 51.

[0070] The beneficial effect of adopting the preferred scheme in the above embodiment is that during installation, after the fixed part of the straight-line rotating shaft 4 is fixedly connected to the support arm 2, the rotating part of the straight-line rotating shaft 4 is inserted into the No. 1 socket 51 of the corresponding No. 1 fixing part 5, thereby realizing the connection and installation of the straight-line rotating shaft 4 and the corresponding No. 1 fixing part 5.

[0071] As a specific solution to the above embodiment, both ends of the inline shaft 4 are flat plate-like structures. This ensures that after the ends are inserted into the number one insertion hole 51, the ends of the inline shaft 4 form a planar contact structure with the wall of the number one insertion hole 51, preventing the rotating portion of the inline shaft 4 from rotating relative to the number one fixing member 5. Furthermore, a slot is provided on the side of the support arm 2 for the end of the inline shaft 4 to be inserted. The inner wall of the slot is adapted to fit the plate-like structure of the end of the inline shaft 4, ensuring that the inline shaft 4 itself does not rotate after being inserted.

[0072] Based on the above embodiment, a bolt hole is provided through the rotating portion of the straight shaft 4 and is threadedly connected with a bolt, so that the rotating portion of the straight shaft 4 and the first fixing member 5 can be detachably connected by the bolt.

[0073] Example 6

[0074] like Figures 4 to 8 Based on Examples 1-5, each No. 2 fixing member 6 includes a hook portion 61 detachably connected to the rotating portion of the corresponding straight shaft 4 and a hanging portion 62 fixedly connected to the hook portion 61, and the hanging portion 62 is used to be installed on the display screen group 3.

[0075] The beneficial effect of adopting the preferred solution in the above embodiment is that during installation, the hanging part 62 is first installed on the display screen group 3 to achieve the fixed installation of the second fixing member 6, and then the straight shaft 4 and the hook part 61 are connected and installed.

[0076] As a specific embodiment of the above embodiment, the hook portion 61 is U-shaped, and the rotating portion of the straight shaft 4 is inserted into the U-shaped opening and is detachably connected to the rotating portion of the straight shaft 4 via bolts. The hook portion 62 is a plate-like structure perpendicular to the hook portion 61, fixedly connected to one arm of the hook portion 61, and detachably connected to the display panel assembly 3 via bolts.

[0077] On the other hand, the present invention provides a display terminal, which is described in detail below.

[0078] Example 7

[0079] like Figures 1 to 11 A display terminal includes an angle-adjustable arm structure as described in any one of Examples 1-6, and also includes a host 1 and a display screen group 3, wherein the two ends of the arm 2 are rotatably connected to the host 1 and the display screen group 3 through two rotating shaft assemblies.

[0080] The beneficial effect of adopting the preferred solution in the above embodiment is that the display screen group 3 is installed on the main unit 1 by using the support arm 2. During use, the angle of the display screen group 3 relative to the support arm 2 can be changed by the rotating shaft assembly located at both ends of the support arm 2, and the angle between the support arm 2 and the main unit 1 can be changed. The opening angle and the use height of the display screen group 3 can be adjusted to ensure that the user can clearly read the treatment information from various angles and under various lighting conditions.

[0081] Example 8

[0082] like Figures 1 to 11 On the basis of Example 7, an arm slot 121 for placing the arm 2 is opened on the upper side of the host 1, and a display screen slot 122 connected to the arm slot 121 is opened on one side in the horizontal direction. The display screen slot 122 is used to place one end of the display screen group 3.

[0083] The beneficial effect of adopting the preferred solution in the above embodiment is that when use is completed, the display screen group 3 is closed, the support arm 2 enters the support arm groove 121, and one end of the display screen group 3 enters the display screen groove 122, ensuring that the host 1 and the display screen group 3 are folded and closed.

[0084] Example 9

[0085] like Figures 1 to 11 On the basis of embodiments 7 and 8, the host 1 includes a host lower shell 11 and a host upper shell 12 detachably connected to the host lower shell 11, and one end of the arm 2 is rotatably connected to the host upper shell 12 through a shaft assembly.

[0086] The beneficial effect of adopting the preferred solution in the above embodiment is that connecting the support arm 2 to the upper shell 12 of the host can reduce the impact on the installation of components inside the host 1 and ensure the installation space of the components.

[0087] Based on the above embodiment, the arm slot 121 and the display screen slot 122 are both opened on the upper side of the main body upper shell 12. When the display screen group 3 is folded, the arm 2 enters the arm slot 121, and the display screen group 3 is closed and folded on the main body upper shell 12.

[0088] The end of the arm slot 121 away from the display screen slot 122 has an opening through the slot wall for insertion of the rotating portion of the inline shaft 4. In this embodiment of the utility model, the two No. 1 fixing members 5 are both mounted on the underside of the main unit upper shell 12, so that the two No. 1 fixing members 5 are concealed between the main unit lower shell 11 and the main unit upper shell 12.

[0089] Based on the above embodiment, the host 1 also includes an MCU mainboard 13, an ultrasonic mainboard 14, a power module mainboard 15 and an output mainboard 16 installed in the lower shell 11 of the main body. The ultrasonic mainboard 14, the power module mainboard 15 and the output mainboard 16 are all communicated or connected to the MCU mainboard 13 by wires. The MCU mainboard 13 is responsible for sending instructions to the ultrasonic mainboard 14. The MCU mainboard 13 controls the output of the power module mainboard 15 through a control signal to supply power through the power module mainboard 15. Other mainboards (such as the MCU mainboard 13, the ultrasonic mainboard 14, the output mainboard 16) provide stable power input.

[0090] The MCU mainboard 13 is the core control unit of the entire system, responsible for receiving external inputs (such as keystrokes and sensor signals), processing the data, and sending control instructions to other mainboards. The MCU mainboard 13 controls the ultrasonic mainboard 14 to transmit and receive ultrasonic waves and processes the returned ultrasonic signals. The MCU mainboard 13 is also responsible for monitoring the output of the power module mainboard 15 to ensure the stability and reliability of the system power supply. Based on the processing results, the MCU mainboard 13 controls the output mainboard 16 to drive external devices to perform corresponding actions.
