Description

Technical Field

[0001] This utility model relates to the field of displays, specifically to a damping hinge structure and computer equipment. Background Technology

[0002] The statements in this section are merely background information relating to this disclosure, and these statements may constitute prior art. In the process of developing this utility model, the inventors discovered at least the following problems in the prior art.

[0003] Plasma is primarily used to produce blood products such as albumin, globulin, clotting factors, and vaccines, and is a life-saving drug for various conditions including burns, liver disease, blood loss, and hemophilia. Currently, human medical technology cannot meet the requirements for artificially synthesizing plasma to produce blood products, making it an irreplaceable clinical treatment drug. Plasma is also an important national strategic reserve material, serving as an emergency medicine in response to sudden emergencies such as natural disasters, wars, and outbreaks of major infectious diseases.

[0004] There are two ways to obtain plasma. One is to donate only plasma, using a plasma collection machine to collect whole blood from the body and separate the plasma, while the remaining blood components are returned to the body. The other is to separate plasma from donated whole blood.

[0005] Equipment such as plasma apheresis machines (for single-plasma collection) or blood component separators (for whole blood separation) require a display for human-computer interaction. The display and the main unit are typically connected by a damped hinge structure. This damped hinge allows for adjustment of the display angle to facilitate use by operators of different heights. It also allows the display to be folded during product transport to reduce packaging size.

[0006] There are three common ways to connect monitor cables to the host computer: The first is to route the cable around the damping hinge, leaving it exposed outside the machine, and then around the hinge area, such as... Figure 2 As shown; the second type is a damping hinge that is straight, occupying the central position, and connected to the monitor. The cable passes through the hinge and the connection in parallel (as shown). Figure 3 (As shown in 4 or 5, these are earlier versions designed by our company); the third type has a hollow damping hinge, with the cable passing through the center of the damping hinge, such as... Figure 6 As shown in Figures 7 and 8, all three types of shaft structures described above have certain drawbacks.

[0007] The first type of exposed wires: The machine has poor waterproofing at the cable location, it looks unsightly, and the cables are easily damaged by external forces when the display screen rotates.

[0008] The second type passes through parallel to the pivot hinge: since the hinge must be located at the center of rotation, such as... Figure 3As shown, the cable size is limited and cannot be too large. If the cable size is to be increased, the internal space must be increased, which requires increasing the external dimensions. This results in problems such as unsightly appearance, large space occupation when folded, and higher processing costs.

[0009] The third type is where the hinge is a hollow, complete circle, such as... Figure 7 As shown, the center is the cable pass hole 12. Since the monitor is connected to the host, one end of the standard cable also has a cable connector 4, such as... Figure 9 As shown. However, if the cable connector is larger than the cable, and the connector cannot pass through the cable guide hole 12, then the cable needs to be passed through the cable guide hole 12 first, and then the cable connector needs to be soldered. This makes the assembly process cumbersome and makes repair and replacement of parts more difficult. If the cable connector can pass through without compromising the assembly process, the hinge and pivot structure need to be made larger, which is not only unsightly but also takes up a lot of space when folded, and the processing cost is also higher.

[0010] To address the above issues, the applicant requests the design of a damped hinge structure that simultaneously meets the following requirements:

[0011] 1. The cables between the monitor and the host are routed through the center of the damping hinge, so that they are not exposed outside the machine, making it more aesthetically pleasing and less susceptible to damage from external forces.

[0012] 2. The damping hinge structure allows for internal wiring while maintaining the same external dimensions of the pivot structure, while accommodating larger cable sizes.

[0013] 3. The damping hinge structure allows for internal wiring without increasing the overall dimensions, while also accommodating cable connections. Furthermore, the absence of exposed cable holes reduces the risk of leakage. Summary of the Invention

Detailed Implementation

[0047] The present invention will be further described below with reference to the accompanying drawings. The embodiments of the present invention are only used to illustrate the present invention and not to limit the present invention. Various substitutions and modifications made in accordance with ordinary technical knowledge and conventional means in the art without departing from the technical concept of the present invention should be included within the scope of the present invention.

[0048] After studying existing display cable routing devices, the applicant discovered that the aforementioned problems mainly stemmed from the fact that existing damping hinge structures all used cable 1 as the central route. Therefore, the applicant improved the structure of the damping hinge 2, allowing cable 1 to run along both sides of the damping hinge 2, thus resolving the aforementioned problems. The specific solution is as follows.

[0049] like Figure 10 As shown in Figure 11, a damping hinge structure includes a display front cover 5 and a damping hinge 2; the display front cover 5 is used to assemble with a display 10; the damping hinge 2 includes an intermediate shaft 7 and two cable guide grooves 3; the intermediate shaft 7 is fixedly connected to the display front cover 5; the cable guide groove 3 includes a nut mounting groove 19 and a semi-open cylinder 20 for assembling cables 1; the two cable guide grooves 3 are symmetrically arranged at both ends of the intermediate shaft 7 for assembling with a display bracket 13; the two ends of the intermediate shaft 7 are respectively provided with threaded connecting rods 9, the connecting rods 9 pass through the nut mounting groove 19, and are movably connected to the cable guide groove 3 through a damping adjusting nut 6, for using the friction between the damping adjusting nut 6 and the nut mounting groove 19 to achieve a damping function.

[0050] Because both ends are semi-open cylinders 20, when installing cable 1, the middle part of cable 1 can be laid flat inside without having to pass the end of cable 1 through the middle. That is, the cable connector 4 does not need to pass through the inside of the damping hinge 2. This allows cable 1 to be crimped with the cable connector 4 first, avoiding the risk that the cable connector 4 is too large to pass through, and also simplifies the assembly process. At the same time, since the intermediate shaft 7 is located in the middle of the monitor's front cover 5, the rotation center of the entire damping hinge 2 is shifted to the inside of the monitor's front cover 5, leaving all the space for cable 1. Therefore, thicker cables 1 can pass through without increasing the size of the hinge structure. Its cylindrical design also effectively protects the cable 1, which is laid flat inside, from damage due to rotation.

[0051] like Figure 12 As shown, the damping hinge structure also includes a display rear cover plate 16, which can be assembled with the display front cover 5 by means of detachable connection such as threaded connection, so that the cable 1 is routed inside the device, avoiding the risk of water leakage at the exposed position of the cable hole 12, and reducing the risk of damage from external forces, resulting in a longer product life and a more beautiful appearance.

[0052] However, because the monitor 10 rotates at a large angle, to prevent the cable 1 from being cut due to the small gap between the cable tray 3 and the monitor's back cover 16 when the monitor rotates, such as... Figure 10 As shown in Figure 11, the semi-open cylinder 20 is provided with a cable passage 8, located at the connection between the semi-open cylinder 20 and the nut mounting groove 19. When the display screen is rotated to the minimum closing angle, the cable 1 is located within the cable passage 8 of the semi-open cylinder 20, as shown in Figure 11. Figure 13 As shown, this avoids the cable 1 being cut due to an insufficient gap between the cable tray 3 and the monitor's rear cover 16. Of course, the space between the monitor's front cover 5 and the monitor's rear cover 16 can also be designed to be larger, which can solve the above problem, but it will inevitably make the whole structure bulky, take up space when folded, and is not aesthetically pleasing.

[0053] To prevent cable 1 from being affected by the cable passage 8 when the display screen rotates, the applicant set the width of the cable passage 8 to be greater than the diameter of cable 1. Furthermore, the damping adjusting nut 6, after being connected to the connecting rod 9, is located within the nut mounting groove 19, such as... Figure 11 As shown, this prevents the damping adjusting nut 6 from being inside the cable passage 8, thereby avoiding obstruction of the cable 1 by the damping adjusting nut 6 or damage caused by scraping against the damping adjusting nut 6 during rotation.

[0054] Because the damping adjustment nut 6 needs to rub against the nut mounting slot 19 of the cable guide 3 to achieve the damping function, the cable guide 3 should remain stationary when the intermediate shaft 7 rotates with the monitor 10. Therefore, the cable guide 3 is fixedly connected to the monitor bracket 13 to achieve the above requirement. In order to better connect the cable guide 3 to the monitor bracket 13, such as... Figure 10 As shown in Figure 11, the rear end of the semi-open cylinder is provided with a mounting plate with a threaded hole 14 for assembling the wire groove 3 with the display bracket 13.

[0055] The monitor front cover 5 can be fixedly connected to the monitor 10, or it can be a component of the monitor 10. The intermediate shaft 7 can be integrally formed with the monitor front cover 5, or it can be integrally formed with the connecting rod 9. To make the damping hinge 2 easier to disassemble and maintain, such as Figure 1 As shown in Figure 14, a mounting post 18 is added to the front cover 5 of the display, and the intermediate shaft 7 is fixedly connected to the front cover 5 of the display through the mounting post 18.

[0056] Mounting column 18 can be as follows Figure 14 There are two, which are fixedly connected to the intermediate shaft 7 by screws or the like. Furthermore, the mounting post 18 can also be adapted to the shape of the intermediate shaft 7, such as... Figure 1 As shown, this allows for a tight fit and saves space.

[0057] like Figure 10 As shown, the nut mounting groove 19 is provided with a damping hinge process hole 15, allowing the connecting rod 9 to pass through the hole and connect to the damping adjusting nut 6. The damping force of the damping hinge 2 can be adjusted by adjusting the degree of connection between the damping adjusting nut 6 and the connecting rod 9. In particular, when the damping hinge force decreases over time, the damping force can be adjusted to maintain the display screen with a suitable angle holding force.

[0058] Since the damping function is achieved through the friction between the damping adjusting nut 6 and the nut mounting groove 19, if an ordinary nut is used, it may fall off during frequent rotation of the display screen. To solve this problem, the damping adjusting nut 6 is a locking nut, which will only tighten with frequent rotation of the display screen and will not fall off.

[0059] To reduce wear caused by friction between the lock nut and the nut mounting groove 19, a shim can be placed between the lock nut and the nut mounting groove 19, and the connecting rod 9 passes through it. A disc-shaped shim is preferred.

[0060] A computer device includes a monitor 10, a host 11, a monitor stand 13, and a cable 1; the monitor stand 13 is mounted on the host 11; one end of the cable 1 is connected to the monitor 10, and the other end is connected to the host 11 via a cable connector 4; it also includes the aforementioned damping hinge structure, disposed between the monitor 10 and the monitor stand 13; the monitor stand 13 also includes a stand back cover 17 for detachable connection with the monitor stand 13.

[0061] This application, while allowing for adjustable monitor angles to facilitate use by operators of different heights, also enables cable 1 to be routed internally within the equipment, reducing the risk of damage from external forces or rotation. Furthermore, this application allows for the use of thicker cable 1 without increasing the size of the monitor hinge connection, thus providing greater flexibility in cable selection. This application also optimizes assembly processability and after-sales maintainability, reducing manufacturing and after-sales costs.

[0062] Unless otherwise specified, fixed connections can be riveting, welding, bolting, etc., while movable connections can be hinged, etc.
