Description

Technical Field

[0001] This application relates to the field of display technology, and more specifically, to a custom multi-functional panel assembly for an all-in-one machine and an all-in-one machine display screen. Background Technology

[0002] Industrial all-in-one computers (ICPCs) and home all-in-one computers (WAPCs) are electronic devices that highly integrate the display screen and the host computer. Due to their compact structure, small footprint, and ease of installation and maintenance, they are widely used in industrial automation control, smart terminal interaction, home office, and entertainment. All-in-one computers typically have a physical control panel located on the bezel or side of their display screen. Users can use shortcut keys on the panel to quickly adjust screen brightness and volume, power on / off, launch specific applications, or execute preset commands, thereby improving the convenience of human-computer interaction.

[0003] In existing technologies, the shortcut key panel on an all-in-one computer display typically uses an independent button structure. Each shortcut key requires an independent pressure-sensitive sensor. When a user presses a shortcut key, the corresponding sensor detects a pressure change or contact activation, generating a corresponding control signal that is sent to the host for processing. While this design enables accurate button function recognition, its structure has significant technical drawbacks: Firstly, because each shortcut key requires an independent pressure-sensitive sensor, the number of sensor components increases linearly with the number of shortcut keys, leading to a significant increase in material costs. Secondly, the layout of multiple sensors requires a large circuit board area inside the panel, along with additional signal processing circuitry and interface pins, increasing not only the complexity of the circuit design but also the difficulty and cost of production and assembly. Furthermore, the use of multiple sensors increases the number of potential failure points in the system, reducing the long-term reliability of the panel assembly. Summary of the Invention

[0004] In view of this, this application provides a custom multi-functional panel assembly for all-in-one machines to solve the technical problems of high component cost, complex circuit layout and high failure rate caused by the shortcut key panel configured on the display screen of the all-in-one machine being equipped with multiple pressure-sensitive sensors.

[0005] This application provides a custom multi-functional panel assembly for an all-in-one machine, wherein the custom multi-functional panel assembly includes a pressure-sensitive sensor, a flexible button film, a guide block and a sensor mounting plate connected in sequence; The pressure sensor is mounted on the sensor mounting plate and faces the guide block; The flexible button membrane has multiple flexible shortcut keys; The guide block has multiple guide channels, each guide channel is aligned with a flexible shortcut key, and each guide channel is provided with a moving trigger. When the flexible shortcut key is pressed and moves toward the guide channel, it can push the moving trigger in the corresponding guide channel to move and press against the pressure sensor. The moving trigger of each guide channel presses against the pressure sensor at different positions.

[0006] Furthermore, the movable trigger is movably engaged with the guide block via an elastic element. When the flexible shortcut key is not subjected to external force, the elastic element keeps the movable trigger in a position where it does not contact the pressure sensor. When the flexible shortcut key is pressed and moves toward the guide channel, it can push the movable trigger in the corresponding guide channel to overcome the elastic force of the corresponding elastic element and move to press against the pressure sensor.

[0007] Furthermore, the movable trigger is a movable rod passing through the corresponding guide channel, and the end of the movable rod facing the flexible key membrane is provided with multiple support arms, which are arranged sequentially at intervals around the axis of the movable rod.

[0008] Furthermore, on the side surface of the guide block facing the flexible key film, multiple grooves are formed around each guide channel. The multiple grooves are connected to the corresponding guide channels. The multiple support arms are slidably limited in the multiple grooves of the corresponding guide channels. When the flexible shortcut key is pressed and moves toward the guide channel, it can touch the end of the corresponding support arm or moving rod.

[0009] Furthermore, each of the sinks is provided with an elastic element mounting cavity, the elastic element being a spring disposed in the elastic element mounting cavity, one end of the spring being connected to the bottom wall of the elastic element mounting cavity, and the other end of the spring being connected to the side of the corresponding load-bearing arm away from the flexible button membrane.

[0010] Furthermore, a pressure arm is provided at one end of the moving rod facing the sensor mounting plate. When the flexible shortcut key is pressed and moves toward the guide channel, each pressure arm presses against a different position of the pressure sensor.

[0011] Furthermore, each of the movable rods is provided with two pressure arms arranged symmetrically along the radial direction of the movable rod.

[0012] Furthermore, the sensor mounting plate is provided with a mounting groove and multiple guide grooves on the side facing the guide block. The multiple guide grooves correspond to the positions of each pressure arm and are connected to the mounting groove. The pressure sensor is disposed in the mounting groove, and the pressure arm is slidably limited in the corresponding guide groove.

[0013] In addition, the present invention also provides an all-in-one display screen, wherein the all-in-one display screen includes a display screen bezel and the aforementioned all-in-one custom multi-functional panel assembly, the all-in-one custom multi-functional panel assembly being embedded in the display screen bezel, and the side of the flexible button film facing away from the guide pad being exposed on the display screen bezel.

[0014] Furthermore, the guide block has a guide rail groove on the side facing the flexible key film. The guide rail groove extends along the arrangement direction of the plurality of flexible shortcut keys and passes through the guide block. A sliding rail is slidably installed in the guide rail groove. A baffle is provided on the sliding rail. A lever is provided at the end of the sliding rail extending out of the guide block. The display screen frame has a straight through groove for the lever to move. When the lever moves along the straight through groove, it can move the baffle between a blocked position and a non-blocked position. In the blocked position, the baffle is located between the moving trigger and the flexible key film. In the non-blocked position, the baffle is away from the gap between the moving trigger and the flexible key film.

[0015] The beneficial effects of the all-in-one machine custom multi-functional panel assembly provided by this invention are as follows: Compared to existing technologies, the all-in-one custom multi-functional panel assembly provided by this invention features multiple flexible shortcut keys on the flexible button film. When these flexible shortcut keys are pressed and move towards the guide channel, they can push the corresponding moving trigger in the guide channel to move and press against the pressure sensor. Since the moving triggers for each guide channel press against the pressure sensor at different positions, multiple flexible shortcut keys can essentially share the same pressure sensor for pressure signal transmission. Because the moving triggers for each guide channel press against the pressure sensor at different positions, the pressure sensor can detect which flexible shortcut key is pressed and send the corresponding instruction signal to the computer. This all-in-one custom multi-functional panel assembly only requires one pressure sensor to obtain the operation information of multiple flexible shortcut keys, simplifying the number of electronic components, reducing component costs, and resulting in a simpler circuit layout and lower failure rate compared to multiple pressure sensors.

[0022] Furthermore, the technical solutions of the various embodiments can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them.

[0023] See Figures 1 to 12 This application provides a custom multi-functional panel assembly for an all-in-one machine, wherein the custom multi-functional panel assembly includes a pressure-sensitive sensor 1, a flexible button film 100, a guide block 200 and a sensor mounting plate 300 connected in sequence. The pressure sensor 1 is mounted on the sensor mounting plate 300 and faces the guide block 200; The flexible keypad 100 has multiple flexible shortcut keys 101, which may include, but are not limited to, "F1", "F2", "F3", "F4", "F5", "ENT", display brightness adjustment key, computer volume adjustment key, power key, etc. The flexible shortcut keys 101 can be flexibly and independently set as needed. The flexible shortcut keys 101 are soft film structures integrally formed with the flexible keypad 100. The guide block 200 has multiple guide channels 201, each guide channel 201 is aligned with a flexible shortcut key 101, and each guide channel 201 is provided with a moving trigger 400. When the flexible shortcut key 101 is pressed and moves toward the guide channel 201, it can push the moving trigger 400 in the corresponding guide channel 201 to move and press against the pressure sensor 1. The moving trigger 400 of each guide channel 201 presses against the pressure sensor 1 at different positions. The guide channel 201 is bidirectionally connected to the two ports of the guide block 200, one port facing the flexible key film 100 and the other port facing the sensor mounting plate 300.

[0024] Because the flexible button film 100 in the all-in-one machine custom multi-functional panel assembly provided by the present invention has multiple flexible shortcut keys 101, when the flexible shortcut keys 101 are pressed and move towards the guide channel 201, they can push the corresponding moving trigger 400 in the guide channel 201 to move and press against the pressure sensor 1. Since the moving trigger 400 of each guide channel 201 presses against the pressure sensor 1 at different positions, it is equivalent to multiple flexible shortcut keys 101 sharing the same pressure sensor 1 for pressure-sensitive signal transmission. This is because the moving trigger 400 of each guide channel 201 presses against... Since the pressure sensor 1 is located in different positions, it can detect which flexible shortcut key 101 is pressed when pressure is applied to different positions. It can then send the corresponding instruction signal of the flexible shortcut key 101 to the computer. It is a known technology that different positions (areas) of the pressure sensor 1 generate different signals when pressed. This all-in-one machine's custom multi-functional panel assembly only needs one pressure sensor 1 to obtain the operation information of multiple flexible shortcut keys 101, which simplifies the number of electronic components, reduces the cost of parts, and compared with multiple pressure sensors 1, the circuit layout is more streamlined and the failure rate is lower.

[0025] According to a specific embodiment of this application, the flexible keypad 100, the guide block 200, and the sensor mounting plate 300 are sequentially connected and can be embedded in the display screen bezel 501. The flexible keypad 100 can be bonded to the guide block 200 with adhesive, and the guide block 200 can be detachably connected to the sensor mounting plate 300 with fasteners such as screws and bolts.

[0026] According to one embodiment of this application, the movable trigger 400 is movably engaged with the guide block 200 via an elastic member. When the flexible shortcut key 101 is not subjected to external force, the elastic member keeps the movable trigger 400 in a position that does not contact the pressure sensor 1. When the flexible shortcut key 101 is pressed and moves toward the guide channel 201, it can push the movable trigger 400 in the corresponding guide channel 201 to overcome the elastic force of the corresponding elastic member and move to press against the pressure sensor 1.

[0027] According to a specific embodiment of this application, the movable trigger 400 is a movable rod 401 that passes through the corresponding guide channel 201. The end of the movable rod 401 facing the flexible key film 100 is provided with a plurality of support arms 402. The plurality of support arms 402 are arranged sequentially at intervals around the axis of the movable rod 401. When the part of the operator's finger pressing the flexible shortcut key 101 is not the middle part of the flexible shortcut key 101, the plurality of support arms 402 can ensure that there are more points to receive the operator's finger pressing.

[0028] According to one embodiment of this application, each movable rod 401 is equipped with four support arms 402, and the four support arms 402 are arranged sequentially at 90° intervals around the axis of the corresponding movable rod 401.

[0029] In another embodiment, the three support arms 402 may be arranged sequentially at 120° intervals around the axis of the corresponding moving rod 401.

[0030] According to one embodiment of this application, a plurality of recesses 202 are formed around each guide channel 201 on the side surface of the guide block 200 facing the flexible key film 100. The plurality of recesses 202 are connected to the corresponding guide channels 201. A plurality of support arms 402 are slidably limited in the plurality of recesses 202 of the corresponding guide channels 201. When the flexible shortcut key 101 is pressed and moves toward the guide channel 201, it can touch the end of the corresponding support arm 402 or the moving rod 401. When the flexible shortcut key 101 is not subjected to external force, the support arm 402 protrudes slightly toward the flexible key film 100 from the recesses 202.

[0031] According to a specific embodiment of this application, each sink 202 is provided with an elastic element mounting cavity 203. The elastic element is a spring 2 provided in the elastic element mounting cavity 203. One end of the spring 2 is connected to the bottom wall of the elastic element mounting cavity 203, and the other end of the spring 2 is connected to the side of the corresponding support arm 402 away from the flexible button film 100.

[0032] In addition, a pressure arm 403 is provided at one end of the moving rod 401 facing the sensor mounting plate 300. When the flexible shortcut key 101 is pressed and moves toward the guide channel 201, each pressure arm 403 presses against different positions of the pressure sensor 1. One of the moving rods 401 (for example, the moving rod 401 facing the pressure sensor 1) can directly press against the pressure sensor 1 without the pressure arm 403 at the end facing the sensor mounting plate 300.

[0033] According to a preferred embodiment of this application, each movable rod 401 is provided with two pressure arms 403 arranged symmetrically along the radial direction of the movable rod 401. When the flexible shortcut key 101 is pressed and moves toward the guide channel 201, the corresponding two pressure arms 403 press against the pressure sensor 1 at the same time, which can make the movement of the movable rod 401 more stable.

[0034] According to a preferred embodiment of this application, the sensor mounting plate 300 is provided with a mounting groove 301 and a plurality of guide grooves 302 on the side facing the guide block 200. The plurality of guide grooves 302 correspond to the positions of each pressure arm 403 and are connected to the mounting groove 301. The pressure sensor 1 is disposed in the mounting groove 301. The pressure arm 403 is slidably limited in the corresponding guide groove 302. The guide groove 302 provides a good limiting and guiding effect on the movement of the pressure arm 403 toward the pressure sensor 1, which can make the movement of the moving rod 401 more stable.

[0035] In addition, the sensor mounting plate 300 has a wire hole 303 at the position corresponding to the mounting slot 301, which facilitates the wire connector or wire harness of the pressure sensor 1 to be led out from the wire hole 303 and connected to the main circuit board of the computer.

[0036] In addition, the present invention also provides an all-in-one display screen 500, wherein the all-in-one display screen 500 includes a display screen bezel 501 and the aforementioned all-in-one custom multi-functional panel assembly, the all-in-one custom multi-functional panel assembly being embedded in the display screen bezel 501, and the side of the flexible button film 100 facing away from the guide pad 200 being exposed on the display screen bezel 501.

[0037] According to one embodiment of this application, a guide rail groove 204 is provided on the side of the guide pad 200 facing the flexible key film 100. The guide rail groove 204 extends along the arrangement direction of the plurality of flexible shortcut keys 101 and passes through the guide pad 200. A sliding rail 3 is slidably installed in the guide rail groove 204. A baffle 4 is provided on the sliding rail 3. A lever 5 is provided at the end of the sliding rail 3 extending out of the guide pad 200. The display screen frame 501 has a straight through groove 502 for the lever 5 to move. When the lever 5 moves along the straight through groove 502, the baffle 4 can be in a baffled position and a non-baffled position. The baffle plate 4 moves between the movable trigger 400 and the flexible button membrane 100 in the partitioned position. In the non-partitioned position, the baffle plate 4 is away from the gap between the movable trigger 400 and the flexible button membrane 100. When the operator pushes the lever 5 to move along the straight through groove 502 so that the baffle plate 4 is between the movable trigger 400 and the flexible button membrane 100, pressing the flexible shortcut key 101 will be blocked by the baffle plate 4 and will not be able to push the movable trigger 400 to move. In this state, it can prevent the pressing of the flexible shortcut key from being accidentally touched or touched by unwanted people (such as children).

[0038] It should be noted that the above embodiments only illustrate preferred embodiments of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting this application. It should be pointed out that those skilled in the art can make several modifications and improvements without departing from the concept of this application, such as combining different features in various embodiments, and these should all fall within the protection scope of this application.
