Description

Technical Field

[0001] This utility model relates to the field of electronic technology, and in particular to a wireless intelligent remote control. Background Technology

[0002] With the rapid development of modern smart devices, the demand for remote control of electronic devices is growing and becoming increasingly sophisticated. Traditional remote controls, relying on conventional up, down, left, and right button layouts, lack sufficient flexibility and accuracy when faced with complex and diverse operational commands, failing to meet users' requirements for precise control. Furthermore, as electronic devices become thinner and more streamlined in design, the structural design of traditional remote controls encounters bottlenecks in adapting to these devices, unable to fully utilize limited space to achieve richer functionality and a superior user experience. Against this backdrop, developing new remote controls with higher operational flexibility, accuracy, and adaptability to diverse device appearances has become a crucial issue urgently needing to be addressed in the field of electronic information and control technology.

[0003] Existing wireless remote controls are still stuck in the traditional layout of up, down, left, and right buttons, as if trapped in an outdated operating system. When faced with complex operating scenarios and high-precision parameter adjustments for smart home appliances, the limitations of this traditional button mode are glaringly exposed. It is completely inflexible, forcing users to perform numerous repetitive and mechanical button clicks. This process is not only cumbersome but also prone to accidental presses, wasting a lot of time and energy. Prolonged use can also lead to finger joint pain and wrist stiffness. Therefore, we propose a wireless smart remote control to solve the aforementioned problems. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] Therefore, the purpose of this utility model is to provide a wireless smart remote control that solves the problem that existing wireless remote controls are always confined to the traditional up, down, left, and right button layout, as if trapped in an outdated operating mode. When faced with complex operating scenarios and high-precision parameter fine-tuning of smart home appliances, the limitations of this traditional button mode are glaringly exposed, completely unable to cope flexibly. Users are forced to perform a large number of repetitive, mechanical button clicks, making the operation cumbersome and prone to accidental touches. This not only wastes a lot of time and energy, but prolonged use can also lead to finger joint pain and wrist stiffness.

[0006] To solve the above-mentioned technical problems, this utility model provides a wireless intelligent remote control, which adopts the following technical solution: It includes a housing, the top of which is provided with an arc-shaped guide groove with a raised arc surface. A multi-directional control lever is movably installed within the arc-shaped guide groove. A three-dimensional limiting guide rail is provided inside the multi-directional control lever. A wireless signal processing unit is fixedly installed inside the housing directly below the multi-directional control lever. A central pressure sensing shaft is vertically installed at the center of the wireless signal processing unit. A spherical coupling slider is provided at the top of the central pressure sensing shaft. The curvature of the spherical coupling slider matches the three-dimensional limiting guide rail. An axial reset elastic body is sleeved around the central pressure sensing shaft. The elastic force of the axial reset elastic body keeps the multi-directional control lever in a reset state. The multi-directional control lever can slide in four directions or be pressed vertically along the arc-shaped guide groove. Vertical pressing triggers the central pressure sensing shaft.

[0007] Optionally, the multi-directional joystick is provided with limiting grooves on its front, back, left, and right sides. A directional trigger micro switch assembly is integrated and installed at the bottom of the limiting groove through an anti-loosening fastening structure. The output end of each micro switch is electrically interconnected with the wireless signal processing unit. The trigger micro switch assembly consists of several directional trigger micro switches. Each limiting groove is specially designed based on the triggering mechanism of the directional trigger micro switch and the movement characteristics of the multi-directional joystick in actual operation. The head of the directional trigger micro switch is adapted to the shape of the corresponding limiting groove.

[0008] Optionally, when an external force is applied to the multi-directional joystick from the front-back or left-right directions, the head of the direction-triggered micro switch will slide in the limiting groove. The direction-triggered micro switch can be triggered when the downward pressure given by the multi-directional joystick reaches the critical value. Moreover, a single operation can only trigger the direction-triggered micro switch in one direction, while the direction-triggered micro switches in other directions are not affected because they have not reached the critical value.

[0009] Optionally, four radial positioning guide posts are arranged in a circular pattern above the wireless signal processing unit, located at the upper left, upper right, lower left, and lower right positions, respectively. Each radial positioning guide post is surrounded by a radial reset elastic body. In its natural state, the radial reset elastic body continuously applies a restoring force toward the center position to the multi-directional joystick, effectively maintaining the center reset state of the multi-directional joystick.

[0010] Optionally, an encoder adjustment module is installed in the rear cavity of the housing. A rotary encoder wheel is axially connected to the left side of the encoder adjustment module. A portion of the rotary encoder wheel is exposed outside the housing through an opening on the left side of the housing. The design of the exposed portion fully considers the human finger operation habits, making it convenient for users to rotate the rotary encoder wheel.

[0011] Optionally, a membrane switch is mounted on the top of the housing using surface mount technology (SMT), and an infrared communication unit is built into the front of the housing.

[0012] In summary, this utility model has at least one of the following beneficial effects: 1. By installing a multi-directional joystick and its cooperating arc-shaped guide groove, three-dimensional limiting guide rail, central pressure sensing shaft, and other structures, it achieves the purpose of innovating the operation mode and breaking through the limitations of traditional operation. The multi-directional joystick can slide flexibly in four directions along the arc-shaped guide groove, changing the traditional remote control's single operation mode that relies only on up, down, left, and right buttons. It can easily cope with complex operation scenarios such as high-precision parameter fine-tuning of smart home appliances. The operation process is smooth and accurate, greatly reducing repetitive and mechanical button clicks by users, effectively avoiding accidental touches, greatly improving operation efficiency, freeing users from the troubles of finger joint pain and wrist stiffness, and bringing users a convenient and efficient operation experience.

[0013] 2. By incorporating limit slides, directional trigger microswitches, encoder adjustment modules, and rotary encoder wheels, precise control and expanded functionality are achieved. The precise cooperation between the limit slides and directional trigger microswitches ensures accurate recognition and execution of directional commands when operating the multi-directional joystick, greatly improving control precision. The encoder adjustment module and rotary encoder wheel provide users with fine-tuning capabilities, a feature lacking in traditional remote controls. In complex operations, users can precisely adjust the controls by rotating the rotary encoder wheel, meeting diverse control needs and effectively solving the problem of traditional remote controls having limited functionality and being unable to handle complex tasks.

[0020] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0021] Example 1, refer to Figure 1-4 In this embodiment, to address the limitations of existing wireless remote controls that are confined to traditional up, down, left, and right button layouts, resulting in outdated operating patterns, the limitations of this traditional button mode are glaringly exposed when facing complex operating scenarios and high-precision parameter adjustments for smart home appliances. This makes it completely inflexible, forcing users to perform numerous repetitive and mechanical button clicks, a process that is cumbersome, prone to accidental touches, and wastes considerable time and energy. Furthermore, prolonged use can lead to finger joint pain and wrist stiffness. Therefore, this utility model discloses a wireless smart remote control.

[0022] The device includes a housing 1. The top of the housing 1 has an arc-shaped guide groove 2 with a raised arc surface. A multi-directional control lever 3 is movably mounted within the arc-shaped guide groove 2. The multi-directional control lever 3 has a three-dimensional limiting guide rail 4 inside. A wireless signal processing unit 5 is fixedly installed inside the housing 1 directly below the multi-directional control lever 3. A central pressure sensing shaft 6 is vertically mounted at the center of the wireless signal processing unit 5. A spherical coupling slider 7 is located at the top of the central pressure sensing shaft 6, and the curvature of the spherical coupling slider 7 matches the three-dimensional limiting guide rail 4. An axial reset elastic body 8 is sleeved around the central pressure sensing shaft 6. The elastic force of the axial reset elastic body 8 keeps the multi-directional control lever 3 in a reset state. The multi-directional control lever 3 can slide in four directions or be pressed vertically along the arc-shaped guide groove 2. Vertical pressing triggers the central pressure sensing shaft 6, which is activated by the arc-shaped guide groove 2 with a raised arc surface. The multi-directional joystick 3 is precisely guided to optimize the operation trajectory and achieve smooth four-way sliding. A three-dimensional limiting guide rail 4 is installed inside the multi-directional joystick 3, paired with a spherical coupling slider 7 at the top of the central pressure sensing shaft 6. The precise matching of their curvatures precisely limits the range and direction of movement of the multi-directional joystick 3, significantly improving operational stability and accuracy. An axial reset elastic body 8 is fitted around the central pressure sensing shaft 6, using its elasticity to keep the multi-directional joystick 3 in a reset state, ensuring readiness to respond to new operation commands and achieving a smooth and continuous operation process. Vertically pressing the multi-directional joystick 3 triggers the central pressure sensing shaft 6, providing users with convenient confirmation of operation methods and diversifying operational functions.

[0023] The multi-directional joystick 3 is provided with limiting grooves 9 on its front, back, left, and right sides. A directional trigger micro switch assembly 11 is integrated and installed at the bottom of the limiting groove 9 through an anti-loosening fastening structure 10. The output end of each micro switch is electrically interconnected with the wireless signal processing unit 5. The trigger micro switch assembly consists of several directional trigger micro switches 12. Each limiting groove 9 is specially designed based on the triggering mechanism of the directional trigger micro switch 12 and the movement characteristics of the multi-directional joystick 3 in actual operation. The head of the directional trigger micro switch 12 is adapted to the corresponding limiting groove 9. By setting specially designed limiting grooves 9 on the front, back, left, and right sides of the multi-directional joystick 3, and integrating the directional trigger micro switch assembly 11 composed of several directional trigger micro switches 12 at the bottom of the groove using an anti-loosening fastening structure 10, and electrically interconnecting the output end of each micro switch with the wireless signal processing unit 5, the purpose of accurately identifying the operation direction and stably transmitting control signals is achieved. The limit slide 9 is designed based on the micro switch triggering mechanism and the movement characteristics of the joystick, so that the head of the directional trigger micro switch 12 is adapted to the slide. During operation, the movement of the multi-directional joystick 3 precisely corresponds to the triggering of a single micro switch, avoiding false triggering, ensuring accurate signal transmission, realizing precise and reliable control of the equipment, bringing users a stable and smooth operating experience, and significantly improving the accuracy and stability of remote control operation.

[0024] When an external force is applied to the multi-directional joystick 33 in the forward / backward or left / right directions, the head of the directional trigger microswitch 1212 slides in the limit groove 99. The downward pressure from the multi-directional joystick 33 causes the directional trigger microswitch 1212 to reach a critical value, triggering it. Only one directional trigger microswitch 1212 can be triggered in a single operation; other directional trigger microswitches 1212 remain unaffected as they have not reached the critical value. Through a carefully designed linkage mechanism between the multi-directional joystick 33 and the directional trigger microswitch 1212, when an external force is applied to the multi-directional joystick 33 in the forward / backward or left / right directions, the head of the directional trigger microswitch 1212 slides in the limit groove 99. The downward pressure from the multi-directional joystick 33 causes the switch to reach the critical value, triggering it. This achieves precise identification of the operating direction, resulting in clear directional commands and accurate equipment response during operation. By setting it to trigger only one directional switch at a time, while other directional switches remain unaffected as they have not reached the critical value, operational conflicts and confusion are avoided, ensuring a stable and orderly operation process and providing users with a smooth control experience.

[0025] Four radial positioning guide posts 13 are arranged in a ring around the top of the wireless signal processing unit 5, located at the upper left, upper right, lower left, and lower right positions respectively. Each radial positioning guide post 13 is surrounded by a radial reset elastic body 14. This radial reset elastic body 14 continuously applies a restoring force towards the center position to the multi-directional joystick 3 in its natural state, effectively maintaining the center reset state of the multi-directional joystick 3. By arranging four radial positioning guide posts 13 in the upper left, upper right, lower left, and lower right positions around the top of the wireless signal processing unit 5, and surrounding each guide post with a radial reset elastic body 14, the purpose of providing all-round and precise reset support for the multi-directional joystick 3 is achieved. This enables the multi-directional joystick 3 to quickly and stably return to the initial center position after any deviation, effectively maintaining the center reset state of the multi-directional joystick 3, ensuring that the starting point of each operation is consistent, improving the continuity and stability of operation, and providing users with a stable and consistent operating feel.

[0026] An encoder adjustment module 15 is installed in the rear inner cavity of the housing 1. A rotary encoder wheel 16 is axially connected to the left side of the encoder adjustment module 15. A portion of the rotary encoder wheel 16 is exposed outside the housing 1 through an opening 17 on the left side of the housing 1. The design of the exposed portion fully considers the human finger operation habits, making it convenient for users to rotate the rotary encoder wheel 16. By installing the encoder adjustment module 15 in the rear inner cavity of the housing 1 and axially connecting the rotary encoder wheel 16 on its left side, the remote control can be equipped with fine adjustment functions, achieving the effect of high-precision parameter adjustment of the controlled device. By opening the opening 17 on the left side of the housing 1 to expose part of the rotary encoder wheel 16, and designing the exposed portion according to the human finger operation habits, the user's operation convenience and comfort are improved. Users can easily and naturally rotate the rotary encoder wheel 16 to efficiently complete fine adjustment operations, thus optimizing the user experience.

[0027] A membrane switch 18 is mounted on the top of the housing 1 using surface mount technology (SMT). An infrared communication unit 19 is built into the front of the housing 1. By mounting the membrane switch 18 on the top of the housing 1 using SMT, the control buttons are installed efficiently and securely, resulting in sensitive operation response, a compact button layout, and durability. By building the infrared communication unit 19 into the front of the housing 1, the remote control is given the ability to transmit and receive infrared signals, enabling stable and convenient remote control of infrared-enabled devices and expanding the applicability of the remote control.

[0028] The specific working principle is as follows: A multi-directional joystick 3, along with its associated arc-shaped guide groove 2, three-dimensional limiting guide rail 4, and central pressure sensing shaft 6, is installed to revolutionize the operating mode and break through the limitations of traditional operation. The multi-directional joystick 3 can slide flexibly in four directions along the arc-shaped guide groove 2, changing the traditional remote control's reliance on only up, down, left, and right buttons. It can easily handle complex operating scenarios such as fine-tuning high-precision parameters of smart home appliances, providing smooth and precise operation. This significantly reduces repetitive and mechanical button clicks, effectively avoids accidental touches, greatly improves operating efficiency, and frees users from finger joint pain and wrist stiffness, bringing a convenient and efficient operating experience. By setting up a limiting slide groove 9, a directional trigger micro-switch assembly 11, an encoder adjustment module 15, and a rotary encoder wheel 16, precise control and expanded functions are achieved. The precise cooperation between the limiting slide groove 9 and the directional trigger micro-switch assembly 11 ensures that directional commands are accurately recognized and executed when the user operates the multi-directional joystick 3, greatly improving control accuracy. The encoder adjustment module 15 and the rotary encoder wheel 16 provide users with fine-tuning capabilities, a feature not found in traditional remote controls. In complex operations, users can precisely adjust the controls by rotating the rotary encoder wheel 16, meeting diverse control needs and effectively solving the problem of traditional remote controls having limited functionality and being unable to handle complex tasks.
