Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of remote controller, in particular to an infrared remote controller. BACKGROUND

[0002] Most of the remote controllers in the prior art are provided with only one infrared emitter, and the signal emission range is narrow, and when in use, the infrared emitter needs to be aimed at the controlled device, so that the infrared emitted by the infrared emitter can be received by the controlled device to realize remote control, otherwise, the controlled device cannot receive the infrared signal and cannot realize remote control, so it can be seen that the current remote controller still has deficiencies in the user's experience. SUMMARY

[0003] The problem solved by the present application is that the signal emission range of the existing remote controller is narrow, and the infrared emitter needs to be aimed at the controlled device when in use, and the user's experience is not good.

[0004] To solve the above problems, the present application provides an infrared remote controller, which comprises a shell, a plurality of infrared emitters are arranged on the shell, the infrared rays emitted by the plurality of infrared emitters form a closed-loop infrared propagation area around the shell, and an infrared receiving device located in the infrared propagation area can receive the infrared rays emitted by the infrared emitters.

[0005] The infrared remote controller of the present application is provided with a plurality of infrared emitters, which can emit infrared rays outward in a wide range of 360 degrees and form a closed-loop infrared propagation area around the shell, as long as the infrared receiving device is located in the infrared propagation area, the infrared rays emitted by the infrared emitters can be received, so that the controlled device does not need to be deliberately aimed when remote controlling, and the user's experience is improved.

[0006] Further, the plurality of infrared emitters are located at the edge of the shell, and the edge of the shell is recessed inward to form a mounting groove for accommodating the infrared emitters.

[0007] In this technical solution, the infrared emitters are placed in the mounting groove to effectively protect the safety of the infrared emitters and prevent them from being damaged by external collisions, and the mounting groove can control the area range of the infrared propagation blind area of the remote controller and control the number of infrared emitters.

[0008] Further, the distance from the infrared emission origin of the infrared emitter to the groove bottom of the mounting groove and the groove opening of the mounting groove is equal.

[0009] In this technical solution, the distance from the infrared emission origin of the infrared emitter to the groove bottom of the mounting groove and the groove opening of the mounting groove is equal, which not only ensures the absolute safety of the infrared emitters, but also makes the emission angle A of the infrared emitters as large as possible, maximizes the infrared propagation area, and minimizes the infrared propagation blind area.

[0010] Further, the shell is discoid, and the plurality of infrared emitters are uniformly distributed in the circumferential direction of the shell.

[0011] In the technical scheme, the plurality of infrared emitters are uniformly distributed in the circumferential direction of the shell to ensure that the remote controller can emit infrared rays in a 360-degree wide range, and the discoid shell makes the remote controller have an elegant appearance, a compact structure, and a delicate design, and is convenient for users to use.

[0012] Further, the intersection of the infrared rays emitted by two adjacent infrared emitters in the circumferential direction of the shell to the nearest distance of the shell is L, and L≤0.5m.

[0013] In the technical scheme, the smaller L is, the greater the signal emission range of the remote controller is, and the smaller the blind area is.

[0014] Further, the emission angle A of the infrared emitter and the number n of the infrared emitters satisfy:

[0015]

[0016] In the formula, r is the distance from the infrared emission origin of the infrared emitter to the center of the shell.

[0017] In the technical scheme, the design satisfying the above relationship can ensure that the least number of infrared emitters are arranged under the conditions that the remote controller satisfies the 360-degree wide range of emitting infrared rays outward and the infrared propagation blind area of the remote controller is small, and the design is beneficial to saving cost.

[0018] Further, the slot opening area of the mounting slot is greater than the slot bottom area.

[0019] In the technical scheme, the mounting slot is in the shape of a circular truncated cone or a prismatic truncated cone.

[0020] Further, the emission angle A of the infrared emitter and the slot opening included angle B of the mounting slot satisfy:

[0021]

[0022] In the formula, Y is the slot bottom width of the mounting slot, and 2z is the slot depth of the mounting slot.

[0023] In the technical scheme, the groove included angle B of the mounting groove is designed according to the emitting angle A of the infrared emitter, so as to ensure that the infrared emitter can emit infrared rays outward in a wide range of 360 degrees, and the protection effect of the mounting groove on the infrared emitter is optimal, because the greater the groove included angle B of the mounting groove is, the higher the risk of the infrared emitter being damaged by external impact is, but the groove included angle B of the mounting groove is too small, which affects the maximization of the emitting angle A of the infrared emitter, and the optimal groove included angle B can be found through the above relationship, which can meet the requirement of the maximization of the emitting angle A and make the protection effect of the mounting groove on the infrared emitter optimal, thereby improving the quality of the infrared remote controller.

[0024] Further, the groove depth 2z of the mounting groove satisfies 5mm≤z≤7mm.

[0025] Further, the groove bottom width Y of the mounting groove satisfies 10mm≤Y≤12mm.

[0026] Beneficial effects: The infrared remote controller has multiple infrared emitters, can emit infrared rays outward in a wide range of 360 degrees, greatly increases the signal emission range of the remote controller, does not need to deliberately aim at the controlled device during remote control, improves the user experience, and has a circular appearance, a small and exquisite structure, simple and clear key setting, and convenient user operation.

[0038] This invention proposes an infrared remote control.

[0039] like Figure 1 As shown, in one embodiment of the invention, the infrared remote control includes a housing 4 and a plurality of infrared transmitters 2 disposed on the housing 4. Typically, the number of infrared transmitters 2 is not less than three, and typically, the infrared transmitters 2 are infrared light-emitting diodes (LEDs), such as... Figure 3As shown, the infrared rays emitted by the plurality of infrared emitters 2 form a closed-loop infrared propagation zone 7 around the housing 4, and the infrared receiving device located in the infrared propagation zone 7 can receive the infrared rays emitted by the infrared emitters 2.

[0040] The infrared remote controller of the present application is provided with a plurality of infrared emitters 2, and can emit infrared rays to form a closed-loop infrared propagation zone 7 in a wide range of 360 degrees around the remote controller, so that the controlled device does not need to be deliberately aligned during remote control, and as long as the controlled device is located in the infrared propagation zone 7, the infrared signal emitted by the remote controller can be received, thereby improving the user experience.

[0041] In the present embodiment, as shown in Figure 1 Preferably, the housing 4 is disc-shaped, and the disc-shaped infrared remote controller has a simple and elegant appearance, a small and delicate structure, and the plurality of infrared emitters 2 are located at the edge of the housing 4 and are uniformly distributed in the circumferential direction of the housing 4, so that 360° range uniform signal control can be conveniently achieved. The upper surface of the housing 4 is provided with a main control switch 1, a sub-control switch 5, and a display screen 3, the main control switch 1 is located at the center of the housing 4 and includes a power-on / off control button, a cooling / heating mode button, and a temperature adjustment button, and the sub-control switch 5 is distributed around the main control switch 1 together with the display screen 3, as shown in Figure 1 The sub-control switch 5 includes a wind speed adjustment button, a wind sweeping button, a mode selection button, and a timing button, so that the infrared remote controller has an elegant appearance, a small and compact size, simple and clear keys, and a uniformly distributed signal emission range, and can achieve wide-range remote control without precise alignment of the controlled device, thereby improving the user experience and facilitating 360° range uniform signal control.

[0042] In the present embodiment, the controlled device can be an air conditioner, a television, a fan, or the like.

[0043] In the present embodiment, as shown in Figure 2 The edge of the housing 4 is inwardly recessed to form a mounting groove 6 for accommodating the infrared emitters 2, and placing the infrared emitters 2 in the mounting groove 6 can effectively protect the safety of the infrared emitters 2 and prevent them from being damaged by external impact, for example, when the infrared remote controller falls to the ground, if the infrared emitters 2 are located outside the housing 4, they are likely to be damaged, but if the infrared emitters 2 are placed in the mounting groove 6, they can be protected from being damaged, thereby helping to improve the service life of the infrared remote controller. In addition, the mounting groove 6 can control the area range of the infrared propagation blind area 8 of the remote controller and control the number of infrared emitters 2.

[0044] Further, in the present embodiment, as shown in Figure 2As shown, the distance from the infrared emission origin of the infrared emitter 2 to the bottom of the mounting groove 6 and the opening of the mounting groove 6 is equal, which is designed to ensure the absolute safety of the infrared emitter 2 and make the emission angle A of the infrared emitter 2 as large as possible, maximize the infrared propagation area 7 and minimize the infrared propagation blind area 8, which is shown as Figures 3-5 As shown, the infrared propagation blind area 8 is approximately an isosceles triangle, and the distance from the farthest point of the infrared propagation blind area 8 to the shell 4 is L, that is, the nearest distance from the intersection of the infrared rays emitted by two adjacent infrared emitters 2 to the shell 4 in the circumferential direction of the shell 4. Generally, the smaller L is, the smaller the infrared propagation blind area 8 of the remote controller is, which is beneficial to achieve wide-range remote control. Preferably, L≤0.5m. This distance is usually where the controlled device exists, so as to ensure that the infrared remote controller can achieve wide-range remote control.

[0045] In the embodiment, as shown in the figure, Figures 2-5 The emission angle A of the infrared emitter 2 and the number n of the infrared emitters 2 satisfy the following relationship:

[0046]

[0047] In the formula, r is the distance from the infrared emission origin of the infrared emitter 2 to the center of the shell 4, as shown in the figure, Figure 2 The position of the infrared emission origin of the infrared emitter 2 is usually the position of the infrared light-emitting diode emission lamp, and 180° / n is half of the included angle between two adjacent infrared emitters 2, as shown in the figure, Figure 4 If r, L and n are known, the emission angle A of the infrared emitter 2 can be calculated, and the design satisfying the above relationship can ensure that the number of infrared emitters 2 is the least under the condition that the remote controller can emit infrared rays in a 360-degree wide range and the infrared propagation blind area 8 is small, which is beneficial to save costs. Of course, the infrared emitters 2 can also be set without meeting the minimum number requirement, which increases the cost, but the signal emission range of the infrared emitter 2 blocked by the hand or foreign matter will be affected less.

[0048] Further, in the embodiment, as shown in the figure, Figure 2 The opening area of the mounting groove 6 is greater than the bottom area, that is, the mounting groove 6 is in the shape of a circular truncated cone or a prismatic truncated cone. In order to ensure that the remote controller can emit infrared rays in a 360-degree wide range and the infrared propagation blind area 8 is small, and make the protection effect of the mounting groove 6 on the infrared emitter 2 optimal, the emission angle A of the infrared emitter 2 and the included angle B of the opening of the mounting groove 6 satisfy the following relationship:

[0049]

[0050] In the formula, Y is the width of the bottom of the mounting groove 6, and 2z is the depth of the mounting groove 6, as shown in the figure,Figure 2 As shown, because the distance from the infrared emission origin of the infrared emitter 2 to the connecting line of the left and right two points of the slot of the mounting groove 6 is very close to the distance from the infrared emission origin of the infrared emitter 2 to the edge of the shell 4, the distance from the infrared emission origin of the infrared emitter 2 to the connecting line of the left and right two points of the slot of the mounting groove 6 can be approximately taken as the distance z in the calculation of the above relationship, which is convenient for calculation. In the specific calculation process, the slot width of the mounting groove 6 is calculated according to the emission angle A of the infrared emitter 2, then the width difference between the slot and the bottom of the mounting groove 6 is calculated, and finally the slot included angle B of the mounting groove 6 is calculated in the right triangle 9.

[0051] In the embodiment, generally, 5mm≤z≤7mm, 10mm≤Y≤12mm, the slot included angle B of the mounting groove 6 is designed by the emission angle A of the infrared emitter 2, which ensures that the protection effect of the mounting groove 6 on the infrared emitter 2 is optimal on the premise that the remote controller can emit infrared rays in a wide range of 360 degrees. Because the greater the slot included angle B of the mounting groove 6 is, the higher the risk of damage of the infrared emitter 2 caused by external impact is, but too small slot included angle B of the mounting groove 6 will affect the maximization of the emission angle A of the infrared emitter 2. An optimal slot included angle B can be found by the above relationship, which can meet the requirement of maximization of the emission angle A and make the protection effect of the mounting groove 6 on the infrared emitter 2 optimal, thereby improving the quality of the infrared remote controller.

[0052] The above only describes the preferred embodiments of the present application, and does not limit the patent scope of the present application. Any equivalent structural transformation, direct / indirect application in other related technical fields, or the like made according to the content of the present application and the drawings, which is within the concept of the present application, is included in the patent protection scope of the present application.
