Description

Technical Field

[0001] The utility model relates to the technical field of wireless controllers, and particularly relates to a remote control and its switching accessories. Background Art

[0002] Remote controls are very common wireless controller devices in current life. Their function is to emit specific signals. When the signals are received by the corresponding receivers, the signals are processed and converted into corresponding instructions to achieve the control of target devices. Therefore, to ensure that the operations of the remote control can smoothly control the target devices, it is crucial whether the signals emitted by the remote control can be smoothly received by the receivers. Therefore, in order to improve the control sensitivity of the remote control, in the design of the remote control, current technicians are all committed to broadening the emission angle range of the remote control. For example, the infrared head of the remote control is protruded, and the area around the infrared head of the remote control is recessed to reduce the occlusion of the infrared head, etc.

[0003] However, with the development of the times, there are more and more devices that need to be controlled by remote controls in the same scenario. For example Figure 1 As shown, a usage scenario of a remote control is illustrated. In the corresponding Figure 1 In the illustrated scenario, multiple sensors are installed and set. The parameter setting and adjustment of such sensors need to rely on the remote control. However, since multiple sensors are set in the same scenario, and currently, the remote controls commonly designed in the industry are all wide-angle designs. When a user uses the remote control and expects to set a single sensor alone, other surrounding sensors are also likely to receive the signals and be mis-set, making it particularly difficult for the user to set a single sensor.

[0004] Although generally speaking, to solve the problem of mis-triggering of multiple devices in the same scenario, it is only necessary to simply narrow the emission angle range of the remote control. However, in fact, due to the extremely large shipment volume of current remote controls, specifically designing a narrow-angle remote control for special usage scenarios means re-designing and re-molding the remote control. Moreover, such special usage scenarios are relatively limited. Designing a narrow-angle remote control specifically has high production costs and small demand, which does not conform to the market rules. For sensor manufacturers, most of the sensors used in the usage scenarios of multiple sensors and single sensors are also of the same type. If two types of remote controls are configured for one type of sensor, it is not realistic, and it will additionally increase costs and cause waste of resources. Even if a narrow-angle remote control is designed and the narrow-angle remote control is used as a supporting general sensor remote control, when the sensor is in a single-sensor usage scenario, due to the narrowing of the emission angle range of the remote control, the user needs to directly face the sensor with the remote control to effectively control the sensor, which affects the user's operation experience.

[0041] The following description is used to disclose the present utility model so that those skilled in the art can implement the present utility model. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations. The basic principles defined in the following description of the present utility model can be applied to other implementation schemes, variant schemes, improvement schemes, equivalent schemes, and other technical schemes without departing from the spirit and scope of the present utility model.

[0042] Those skilled in the art should understand that in the disclosure of the present utility model, the orientation or positional relationships indicated by the terms "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on the present utility model.

[0043] It can be understood that the term "a" should be understood as "at least one" or "one or more". That is, in one embodiment, the number of an element can be one, while in other embodiments, the number of the element can be multiple. The term "a" should not be construed as a limitation on the quantity.

[0044] Referring to Figures 2 to 7 of the specification drawings of the present utility model, a remote controller and its switching accessory according to an embodiment of the present utility model are schematically shown. The remote controller can be freely switched between a wide-angle mode and a narrow-angle mode to flexibly cope with different usage scenarios. Moreover, without re-designing and re-molding the existing remote controller, the response range angle of the wide-angle remote controller commonly designed in the current industry can be switched to a narrow angle, which is suitable for modifying the existing remote controller.

[0045] Specifically, the remote controller includes a remote controller body 10 and a switching accessory 20. The remote controller body 10 has an infrared head 101. One end of the remote controller body 10 with the infrared head 101 is defined as the head 11 of the remote controller body 10. The switching accessory 20 is adapted to be detachably mounted on the head 11 of the remote controller body 10 and has a light-transmitting channel 201. In the state where the switching accessory 20 is mounted on the remote controller body 10, the switching accessory 20 masks the emission path of the infrared head 101, and the infrared head 101 emits signals through the light-transmitting channel 201. Based on the masking of a partial emission path of the infrared head 101 by the switching accessory 20, as Figure 6 shown, especially the masking of the emission paths on both sides of the central axis of the infrared head 101, thus narrowing the emission angle range of the infrared head 101.

[0046] It is worth mentioning that the remote controller body 10 can be an existing remote controller. For example, it can be a remote controller for household appliances such as televisions, air conditioners, fans, lamps, and audio systems, or a remote controller for intelligent sensors such as infrared sensors, pyroelectric sensors, and microwave sensors, used for controlling the distance setting, detection area setting, high and low sensitivities, on / off, etc. of the sensors. The present invention does not limit this. In other words, based on the setting of the switching accessory 20, the remote controller body 10 can achieve free switching between a wide-angle mode and a narrow-angle mode, and thus is also applicable to upgrading and improving existing remote controllers, improving the adaptability of existing remote controllers to different scenarios without increasing the cost of re-designing and re-molding the remote controller.

[0047] Particularly, in the state where the switching accessory 20 is mounted on the remote controller body 10, the switching accessory 20 masks the emission path of the infrared head 101, and the infrared head 101 emits signals through the light-transmitting channel 201, so as to standardize the signal emission directivity of the infrared head 101 based on the light-transmitting channel 201, thereby improving the control targeting of the remote controller and effectively avoiding mis-triggering.

[0048] It is worth mentioning that the switching accessory 20 is detachably mounted on the remote control body 10. Based on the selective installation of the switching accessory 20, the remote control has a narrow-angle mode in which the switching accessory 20 masks the infrared head 101, and a wide-angle mode in which the infrared head 101 is not masked by the switching accessory 20. That is, when the switching accessory 20 is mounted in front of the infrared head 101, partial blocking of the infrared head 101 is formed, so that the infrared head 101 can only emit signals through the light-transmitting channel 201, thereby reducing the emission angle size of the remote control. When the switching accessory 20 is removed from in front of the infrared head 101, the infrared head 101 is not blocked by the switching accessory 20 and can emit signals at the angle size originally designed for the remote control body 10, thereby switching the response range angle of the remote control between wide angle and narrow angle to flexibly cope with different usage scenarios.

[0049] Furthermore, to ensure the firmness of the installation of the switching accessory 20, the switching accessory 20 is detachably mounted on the remote control body 10 in a manner of being sleeved on the remote control body 10. Specifically, the switching accessory 20 has a cap 21, and the cap 21 has a structural form matching the head 11 of the remote control body 10 and is suitable for being sleeved on the head 11 of the remote control body 10. The switching accessory 20 is mounted on the remote control body 10 in a state where the cap 21 is sleeved on the head 11 of the remote control body 10. Based on the sleeving of the cap 21 on the remote control body 10, the remote control body 10 constitutes a limit for the switching accessory 20 and forms an engagement between the remote control body 10 and the cap 21 to ensure the firmness of the switching accessory 20 on the remote control body 10. The light-transmitting channel 201 is provided on the cap 21 and is opposite to the infrared head 101 in a state where the cap 21 is sleeved on the head 11 of the remote control body 10, so as to ensure that in a state where the cap 21 is sleeved on the remote control body 10, the infrared head 101 can face the light-transmitting channel 201, so that the infrared head 101 can emit signals through the light-transmitting channel 201.

[0050] It is worth mentioning that the cap 21 can be set to have a certain elastic deformation force, for example, it can be set as a soft silicone sleeve, so that the force of the cap 21 sleeved on the head 11 of the remote control body 10 can be increased based on the elastic deformation of the cap 21. It can be understood that the cap 21 can also adopt a hard body design, and the firmness of the installation of the switching accessory 20 is ensured based on the engagement between the cap 21 and the head 11 of the remote control body 10. The present utility model does not limit this.

[0051] Further, to improve the response directivity of the remote control in the narrow-angle mode, the light-transmitting channel 201 extends outward from the cap 21. Specifically, the switching accessory 20 extends outward from the cap 21 to have a light-emitting tube 22, and the light-emitting tube 22 forms the channel wall of the light-transmitting channel 201, defining the light-transmitting channel 201. In the state where the switching accessory 20 is installed on the remote control body 10, the infrared head 101 emits signals outward through the light-transmitting channel 201.

[0052] It is worth mentioning that the light-emitting tube 22 extends straight from the cap 21 to improve the directivity of the remote control, thereby improving the control pertinence of the remote control and effectively avoiding mis-triggering.

[0053] In particular, based on the design of the light-transmitting channel 201 protruding from the cap 21, when the user uses the remote control, the user can clarify the direction of the remote control based on the direction of the light-emitting tube 22, so that the user can control the corresponding device pertinently.

[0054] It is worth mentioning that based on the design of the light-transmitting channel 201 protruding from the cap 21, the switching accessory 20 is also applicable to the existing remote control design in which the infrared head 101 protrudes from the head 11 of the remote control body 10, improving the adaptability of the switching accessory 20 to different types of remote controls.

[0055] It is worth mentioning that in some embodiments of the present invention, based on the form of the remote control body 10 shown in the present invention and the design that the infrared head 101 is recessed in the head 11 of the remote control body 10, the light-transmitting channel 201 can also extend inward from the cap 21. For example, the light-emitting tube 22 extends inward. In the state where the switching accessory 20 is installed on the remote control body 10, the light-emitting tube 22 is wound around the infrared head 101, and the infrared head 101 can emit signals outward through the light-transmitting channel 201.

[0056] Further, on the channel wall 22 of the light-transmitting channel 201 of the switching accessory 20 and in the area around the cap 21 located on the channel wall 22, for example, the top end 211 of the cap 21 is designed to be light-shielded. For example, black materials, light-colored materials doped with corresponding light-shielding substances, etc. are used to manufacture the switching accessory 20. Specifically, for example, a black panel, a white panel doped with calcium carbonate, etc. are used, or an opaque layer is covered on the switching accessory 20. The opaque layer can cover both the inner wall and the outer wall of the switching accessory 20, so as to realize the light-shielding of the light emitted by the infrared head 101, so that the infrared head 101 can only output signals through the light-transmitting channel 201.

[0057] It is worth mentioning that the switching fitting 20 is designed to be light-shielded on the channel wall 22 of the light-transmitting channel 201 and the cap 21 in the area around the channel wall 22. It can be that the switching fitting 20 only adopts a light-shielding design on the channel wall 22 of the light-transmitting channel 201 and the cap 21 in the area around the channel wall 22, and the rest can adopt a non-light-shielding design, such as being transparentized, etc., or the switching fitting 20 can be entirely designed to be light-shielded.

[0058] Specifically, the light-transmitting channel 201 is preferably set to have a certain length. For example, the length of the light-emitting tube 22 is set to be greater than or equal to 3 mm to ensure that the response range of the switching fitting 20 to the remote control is narrowed.

[0059] Furthermore, the remote control body 10 has a front surface 12 provided with a corresponding control module and a back surface 13 opposite to the front surface 12. The cap 21 has a front groove wall 212 corresponding to the front surface 12 and a back groove wall 213 corresponding to the back surface 13. The front groove wall 212 is recessed and hollowed out in the direction of the light-transmitting channel 201 to form a top surface opening 2121, so as to prevent the switching fitting 20 from affecting the normal operation of the remote control body 10, that is, to prevent the switching fitting 20 from blocking the control module on the front surface 12 of the remote control body 10.

[0060] It can be understood that the control module on the remote control body 10 can be a physical button or a touch screen, etc., and the present invention does not limit this.

[0061] Specifically, the back surface 13 is provided with at least one positioning bump 131, and the back groove wall 213 is provided with at least one positioning hole 2131 matching the positioning bump 131. In the state where the cap 21 is sleeved on the head 11 of the remote control body, the positioning bump 131 is inserted into the positioning hole 2131 to realize the positioning and limiting of the switching fitting 20. The positioning bump 131 can be the placement fulcrum provided on the back of many current remote controls. The present invention uses the structural design of the remote control itself to position and limit the switching fitting 20, thus not increasing the design and mold opening costs of the remote control.

[0062] It is worth mentioning that the remote control body has two side surfaces 14 connecting the front surface 12 and the back surface 13, and the cap 21 has two side insertion walls 214 corresponding to the side surfaces 14. In the state where the cap 21 is sleeved on the remote control body, the two side surfaces 14 are held between the two side insertion walls to form left and right limiting of the switching fitting 20.

[0063] That is to say, based on the setting of the switching accessory 20, the control directivity of the remote controller can be improved, so that mis-triggering of the device can be effectively avoided in a multi-device scenario. At the same time, the switching accessory 20 can be flexibly detached from the remote controller body 10, so that the user can also use the remote controller to control the device at a wide angle in a single-device scenario. And based on the setting of the switching accessory 20, the present utility model does not need to re-design and re-mold the existing remote controller, effectively reducing the cost, and can also be applied to the lifting transformation of the existing remote controller without replacing the remote controller, thus effectively avoiding waste of resources.
