Description

Technical Field

[0001] The present invention relates to an encoder, in particular to an encoder with a light emitting diode, or an encoder with both a light emitting diode and a key switch, and is suitable for electronic products, such as but not limited to encoders for audio equipment, mixing engineering equipment, audio-visual equipment, etc. Background Art

[0002] Encoders are commonly used in electronic products to provide coded signals, such as high and low potential signals.

[0003] In addition, for general electronic products, such as but not limited to audio equipment, mixing equipment, audio-visual equipment, etc., they usually have a control shaft, and the so-called switch function of the switch device of the electronic product can be achieved by pressing the control shaft. In order to enhance the function of the switch device of the electronic product, an encoder is often assembled on the switch device, so that the switch device has both the switch and encoding functions.

[0004] However, in dimly lit places, such as movie theaters or homes, when audio-visual equipment is turned off, lights are needed to guide the user when using the switch device of the audio-visual equipment. Traditionally, light-emitting diodes are set on the substrate of the above-mentioned electronic products to generate light, but when setting the light-emitting diodes on the substrate, the position of the above-mentioned encoder must be matched, so the height and brightness of the light-emitting diodes are not easy to integrate. Moreover, when setting the light-emitting diodes, the process steps will also increase, such as the need to add additional soldering processes to set the light-emitting diodes on the substrate, so the process time will increase and the cost will also increase.

[0005] In addition, the encoder currently installed in the switch device is usually a contact encoder, which requires a brush to contact the metal contact to generate a pulse signal, and the switch module containing the light-emitting diode also uses a brush to contact the metal contact to energize, which is easy to cause wear and tear, resulting in a shortened product life.

[0006] Therefore, the inventor, in the spirit of active invention and creation, was eager to think of an "encoder with light emitting diodes" that could solve the above-mentioned problems, and finally completed the present invention after several studies and experiments. Summary of the invention

[0007] One purpose of the present invention is to provide an encoder with a light emitting diode, which can avoid the problem of reduced product life due to brush contact wear in the prior art through a non-contact magnetic sensor. In addition, the encoder of the present invention can be equipped with a light emitting diode to meet the personalized needs of different users. In addition, the encoder of the present invention can be combined with a switch function, which can trigger the electrical contacts of the switch without interfering with the light emitting diode through the combination of the control shaft and the pressing drive body, thereby improving the life and quality of the product.

[0008] To achieve the above-mentioned purpose, the encoder with a light-emitting diode of the present invention comprises: a light-emitting diode, an insulating base, a conductive spring, a pressing driving body, an encoder component and a control shaft. The insulating base has a main chamber and a terminal portion. The conductive spring is accommodated in the main chamber and is located above the terminal portion. The pressing driving body is accommodated in the main chamber and is located above the conductive spring, and has a accommodating portion for accommodating the light-emitting diode. The encoder component is at least partially accommodated in the main chamber, and comprises a magnetic component and a magnetic sensor, and the magnetic component has a through hole. The control shaft passes through the through hole and is located above the pressing driving body. Thereby, the encoder with a light-emitting diode of the present invention can solve the problems of the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

[0092] Please refer to Figure 1 . Figure 1 FIG. 1 is an exploded view of an encoder 1 with light emitting diodes according to an embodiment of the present invention.

[0093] like Figure 1 As shown, the encoder 1 with light emitting diode of the present invention mainly includes: a switch module A, an encoder module B, a control shaft 2 and a light emitting diode 7. The switch module A may include a pressing driving body 8, a conductive spring 9, an insulating base 10 and a terminal portion 15. The encoder module B may include a magnetic sensor 3, a magnetic ring 4 and a rotating driving body 5. For the convenience of explanation, the normal direction of the encoder 1 of the light emitting diode is defined as the Z direction below. In addition, the relative relationship of the "top", "bottom", "above" or "below" of the components below is the relative position in the Z direction.

[0094] First, switch module A is explained. Please also refer to Figures 1 to 2B ,in Figure 2A is a partial exploded view of a switch module A according to an embodiment of the present invention. Figure 2B FIG. 1 is a schematic diagram of an assembled switch module A and a light emitting diode 7 according to an embodiment of the present invention. Figure 2CFIG. 1 is a top view of an insulating base 10 according to an embodiment of the present invention.

[0095] like Figure 1 , 2A As shown in 2C, the insulating base 10 may have a main chamber 100, for example, an upper surface 10a of the insulating base 10 is recessed with the main chamber 100, and the main chamber 100 includes a first sub-chamber 101 and a second sub-chamber 102, wherein in the Z direction, the lower part of the first sub-chamber 101 may be connected to the second sub-chamber 102, and the projection of the first sub-chamber 101 in the Z direction may surround the projection of the second sub-chamber 102 in the Z direction. The first sub-chamber 101 and the second sub-chamber 102 have different sizes and / or shapes, for example, the first sub-chamber 101 may correspond to (for example, slightly larger than or equal to) the size and / or shape of the rotating driving body 5 of the encoder module B, so that the rotating driving body 5 can be accommodated and placed in the first sub-chamber 101, and for another example, the second sub-chamber 102 may correspond to the size and / or shape of the pressing driving body 8, so that the pressing driving body 8 can be accommodated and placed therein, but it is not limited thereto.

[0096] In one embodiment, the insulating base 10 may further have a side chamber 103, and in a horizontal direction (such as ±X direction, ±Y direction or other direction perpendicular to the Z direction), the side chamber 103 is adjacent to the first sub-chamber 101. The side chamber 103 may correspond to the size and / or shape of the magnetic sensor 3 of the encoder module B, so that the magnetic sensor 3 can be accommodated and placed therein. The number or adjustment range may also be changed according to the specification requirements of different sensors.

[0097] The insulating base 10 may have a terminal portion 15 inside. The terminal portion 15 may be located at the bottom of the main chamber 100, but is not limited thereto. Further, the terminal portion 15 may include, for example, a first terminal 17 and a second terminal 18, wherein the first terminal 17 and the second terminal 18 are not connected to each other.

[0098] In one embodiment, the first terminal 17 may include an inserting portion 171, a connecting portion 172, and an abutting portion 173, wherein the inserting portion 171 is connected to the connecting portion 172, and there is a bend between the two, and the abutting portion 173 extends from the connecting portion 172. In one embodiment, the inserting portion 171 may extend along the -Z direction, the abutting portion 173 may extend along the X direction, and the connecting portion 172 may extend along the Y direction, and is not limited thereto. The second terminal 18 may include an inserting portion 181, an extending portion 182, and an abutting portion 183, wherein the inserting portion 181 is connected to the connecting portion 182, and there is a bend between the two, and the abutting portion 183 extends from the connecting portion 182. In one embodiment, the inserting portion 181 may extend along the -Z direction, the abutting portion 183 may extend along the -X direction, and the connecting portion 182 may extend along the Y direction, and is not limited thereto. In one embodiment, the abutting portion 173 of the first terminal 17 and the abutting portion 183 of the second terminal 18 may have different shapes and may be located at different heights (eg, different heights in the Z direction), but are not limited thereto.

[0099] The conductive spring 9 can be accommodated and placed in the second sub-chamber 102 and located above the terminal portion 15. For example, the conductive spring 9 can be accommodated and placed in the second sub-chamber 102 and located above the abutting portion 173 of the first terminal 17 and the abutting portion 183 of the second terminal 18. The conductive spring 9 can be an arc-shaped conductive spring or other non-planar conductive spring, which can be squeezed by external force to change shape or position, and when the external force is removed, it can return to its original shape or position.

[0100] The pressing driving body 8 can be accommodated and placed in the second sub-chamber 102 of the main chamber 100, and is located above the conductive spring sheet 9. The pressing driving body 8 itself can have a accommodating portion 81, and the accommodating portion 81 can correspond to the shape of the light-emitting diode 7, thereby being used to accommodate and place the light-emitting diode 7. It should be noted that when the light-emitting diode 7 is accommodated and placed in the accommodating portion 81, the height of the light-emitting diode 7 in the Z direction is not higher than the upper edge of the pressing driving body 8, so the light-emitting diode 7 will not be exposed from the upper edge of the pressing driving body 8, and therefore when an external force is applied toward the pressing driving body 8, the light-emitting diode 7 can be avoided and will not be interfered with. In addition, the insulating base 10 can have at least one second accommodating portion 107. When the light-emitting diode 7 and the pressing driving body 8 are installed on the insulating base 10, the second accommodating portion 107 can be used to accommodate the pin 71 of the light-emitting diode 7, but is not limited to this.

[0101] In one embodiment, the switch module A may further include at least one steel ball 11 and at least one spring 12 (eg Figure 1 As shown in FIG. 1 , the insulating base 10 may have at least one third receiving portion 108, and the third receiving portion 108 may be used to receive the steel ball 11 and the spring 12, and in the Z direction, the steel ball 11 is disposed on the spring 12. The functions of the steel ball 11 and the spring 12 will be described in the following paragraphs.

[0102] In addition, in one embodiment, the switch module A can be assembled with a fixing plate 13 (eg Figure 1 As shown), the fixing plate 13 has pins 135, so that the encoder body can be positioned on a counterpart (such as but not limited to a PCBA, not shown in the figure), but not limited thereto.

[0103] like Figure 2B As shown, when the switch module A is assembled, the pressing driving body 8 can be located in the second sub-chamber 102 (please refer to Figure 2A ), the insertion portion 171 of the first terminal 17 and the insertion portion 181 of the second terminal 18 can be exposed at the bottom of the switch module A. In addition, when the light-emitting diode 7 is accommodated and placed in the pressing driving body 8, the pin 71 of the light-emitting diode 7 can be exposed at the bottom of the switch module A. In addition, when the magnetic sensor 3 is accommodated and placed in the side chamber 103, the pin 31 of the magnetic sensor 3 can be exposed at the bottom of the switch module A through the through hole 103h on the side chamber 103. Thereby, when the switch module A is set on a circuit board, the insertion portions 171, 181, the contact portion 135, and / or the pins 31, 71 can be electrically connected to the contacts on the circuit board, and are not limited thereto.

[0104] By this, the switch module A can be understood.

[0105] Next, the encoder module B is described. Please also refer to Figure 1 , FIG. 3A to FIG. 3C . Figure 3A It is a schematic diagram of the partial structure of the encoder module B and the control axis 2 according to an embodiment of the present invention. Figure 3B It is a schematic diagram of the combination of the magnetic ring 4, the rotary driving body 5 and the control shaft 2 according to an embodiment of the present invention. Figure 3C 1 is a top view of an encoder module B according to an embodiment of the present invention.

[0106] like Figure 1 , Figure 3A and Figure 3B As shown, the projection of the outer circumference of the magnetic ring 4 in the Z direction may be, for example, a circle or a nearly circle, and the projection of the inner circumference of the magnetic ring 4 in the Z direction may be, for example, an ellipse-like shape with two cut edges 4e, but is not limited thereto, and may also be other shapes with two cut edges 4e. Figure 3C As shown, in one embodiment, the magnetic ring 4 may include a plurality of staggered first magnetic poles (eg, N poles) 41 and second magnetic poles (eg, S poles) 42. In one embodiment, the first magnetic poles (N poles) 41 and the second magnetic poles (S poles) 42 have the same number.

[0107] Another example Figure 1 , Figure 3A and Figure 3BAs shown, the rotary driving body 5 has an upper surface 5a, wherein the upper surface 5a has a protruding structure 51, the protruding structure 51 extends along the Z direction, and the through hole 5S is located in the protruding structure 51. In addition, in one embodiment, the rotary driving body 5 also has a toothed structure 52, which is arranged relative to the upper surface 5a, wherein the toothed structure 52 has a plurality of sub-teeth 53 arranged along the edge of the rotary driving body 5, and each sub-teeth 53 faces the -Z direction, for example, the tip of the sub-teeth 53 can be away from the upper surface 5a. In one embodiment, the shape of the sub-teeth 53 can be, for example, a triangle or a quasi-triangle, but can also be other shapes, such as a semicircle, etc., and is not limited thereto. It should be noted that there can be a sub-tooth spacing space 531 between adjacent sub-teeth 53.

[0108] In one embodiment, the projection of the outer periphery of the rotating driving body 5 in the Z direction may be, for example, a circle or a nearly circle. The projection of the outer periphery of the protruding structure 51 in the Z direction may be an ellipse-like shape with two cut edges 5e, and may correspond to the shape and / or size of the inner periphery 4c of the magnetic ring 4, so that the magnetic ring 4 can be sleeved on the protruding structure 51 and tightly engaged, and then the magnetic ring 4 and the rotating driving body 5 can be fixed together. In addition, the projection of the inner periphery of the protruding structure 51 (that is, the outline of the through hole 5S) in the Z direction may be an ellipse-like shape (or other shapes) with two cut edges 5f, and a bottom 21 of the control shaft 2 may correspond to the shape and / or size of the inner periphery 51d of the protruding structure 51, so that the bottom 21 of the control shaft 2 can pass through the through hole 5S, so that the control shaft 2 can drive the rotating driving body 5 to rotate in the horizontal direction. In addition, it should be noted that in the vertical direction, through the structural shape matching between the control shaft 2 and the bearing 16 (such as Figure 5A As shown), the control axis 2 can move in the Z direction.

[0109] like Figure 3C As shown, when the encoder module B is placed on the insulating base 10, the magnetic sensor 3 can sense the magnetic poles of the magnetic ring 4 and output a signal according to the sensed magnetic poles of the magnetic ring 4. Therefore, when the control shaft 2 rotates, it can simultaneously drive the rotating driving body 5 and the magnetic ring 4 fixedly arranged on the rotating driving body 5 to rotate together, and the magnetic poles sensed by the magnetic sensor 3 will also change due to the rotation of the magnetic ring 4. Thereby, the output of the magnetic sensor 3 can be controlled by rotating the control shaft 2 to be used as an encoder, but it is not limited to this. In one embodiment, the encoder can output one or more signal channels, but it is not limited to this. In one embodiment, the magnetic sensor 3 can have one or more pins, and the number of its pins is not limited.

[0110] By this, encoder module B can be understood.

[0111] Next, the diffuser 6, the bearing 16 and the control shaft 2 of the encoder 1 with light emitting diodes are described. Please refer to Figure 1 .

[0112] like Figure 1 As shown, in one embodiment, the encoder 1 with light emitting diodes may further include a diffuser 6, which may be disposed above the light emitting diodes 7, and the control shaft 2 may pass through the through hole 5S and be located above the diffuser 6. The diffuser 6 may be made of a light-transmitting material or at least partially of a light-transmitting material, and is not limited thereto. It should be noted that in other embodiments, the encoder 1 with light emitting diodes may not have the diffuser 6.

[0113] In one embodiment, the encoder 1 with a light emitting diode may further include a bearing 16, and the bearing 16 has a through hole 16S. The bearing 16 can be sleeved on the control shaft 2 through the through hole 16S and is located on the insulating base 10, wherein a portion of the control shaft 2 can be exposed outside the bearing 16. In addition, the control shaft 2 can rotate relative to the bearing 16. In one embodiment, the bearing 16 may have a thread 161 for locking with a tool other than the present invention (such as a nut), but is not limited to this. In one embodiment, the bearing 16 may have an upper surface 16a, and the upper surface 16a is provided with one or more fixing holes 162, wherein the fixing hole 162 of the bearing 16 can be aligned with one or more fixing holes 106 (shown in Figure 1 and 2A ) and one or more fixing holes 136 of the fixing plate 13 (shown in Figure 1 ), and thus the bearing 16, the insulating base 10 and the fixing plate (13) can be locked together by the fixing member 14, but is not limited thereto.

[0114] In another embodiment, at least a portion of the control shaft 2 may be made of a light-transmitting material. Furthermore, the control shaft 2 may be made of a fully light-transmitting material, wherein the material type may include acrylic, PC, other suitable materials, or any combination thereof, and is not limited thereto; or, the control shaft 2 may also be a partially light-transmitting and partially opaque structure, such as a portion made of metal material and a portion made of a light-transmitting material, and is not limited thereto. Therefore, the light emitted by the light-emitting diode 7 may be dispersed to the outside through the control shaft 2. In addition, if Figure 5A As shown, in another embodiment, the control shaft 2 may be made of an opaque material. In this case, the interior of the control shaft 2 may be a hollow structure, so that the light emitted by the light emitting diode 7 may be dispersed outward through the hollow structure, and the present invention is not limited thereto.

[0115] Figure 4 FIG. 1 is a schematic diagram of an assembled encoder 1 of a light emitting diode according to an embodiment of the present invention. Figures 1 to 3C As a reference aid.

[0116] In one embodiment, when the LED encoder 1 is disposed on a circuit board (not shown), the pin 71 of the LED 7 (shown in FIG. Figure 2A) can be electrically connected to an external circuit (not shown) on the circuit board to be controlled by the external circuit to emit light and adjust the color of the light, but is not limited to this.

[0117] Next, the operation of the encoder 1 with a light emitting diode as a push switch is described. Figure 1 , Figure 5A and Figure 5B . Figure 5A 1 is a cross-sectional view of an encoder 1 with a light emitting diode according to an embodiment of the present invention, taken along line A1 - A1 ′ before the control shaft 2 is pressed. Figure 5B FIG. 1 is a cross-sectional view of an encoder 1 with a light emitting diode according to another embodiment of the present invention, taken along line A1-A1' after the control shaft 2 is pressed. Figure 5A Shows the situation before the switch is pressed. Figure 5B Displays the switch after it is pressed. In addition, Figure 5A and Figure 5B It corresponds to Figure 4 The cross section formed by the A1-A1' section line.

[0118] like Figure 5A and Figure 5B As shown, when an external force is applied to the control shaft 2 so that the control shaft 2 moves toward the pressing driving body 8, the control shaft 2 can abut against the diffuser 6, and the diffuser 6 can abut against the pressing driving body 8 after being subjected to the force (if the encoder 1 does not have a diffuser 6, for example, the control shaft 2 can be designed to directly abut against the pressing driving body 8). After the pressing driving body 8 is subjected to the force, it can abut against the conductive spring 9, and the conductive spring 9 moves downward after being subjected to the force to achieve the electrical connection between the first terminal 17 and the second terminal 18, thereby achieving the function of opening the switch. In one embodiment, the conductive spring 9 can be designed to contact one of the first terminal 17 and the second terminal 18 before being subjected to the force, and not to contact the other one, and the conductive spring 9 will only contact the other one after being subjected to the force, and is not limited to this. In another embodiment, the conductive spring 9 can also be designed to not contact the first terminal 17 and the second terminal 18 before being subjected to the force, and will only contact the first terminal 17 and the second terminal 18 after being subjected to the force, and is not limited to this. In addition, when the external force applied to the control shaft 2 is removed, the conductive spring 9 can bounce up by its own elastic force and return to its original state or position, so that the first terminal 17 and the second terminal 18 are restored to an electrically disconnected state, thereby achieving the off function of the switch.

[0119] Please refer to Figures 4 to 6 ,in Figure 6 is a cross-sectional view of an encoder 1 with a light emitting diode according to an embodiment of the present invention taken along line B1-B1', which corresponds to Figure 4 The section formed by the B1-B1' section line in Figure 6As shown, the steel ball 11 may be correspondingly arranged below the toothed structure 52 of the rotary driving body 5, and the spring 12 may be arranged below the steel ball 11. In one embodiment, when the rotary driving body 5 rotates, the toothed structure 52 may rotate in the horizontal direction, and during the rotation process, the steel ball 11 may contact the sub-teeth 53 of the toothed structure 52 or be located in the sub-teeth spacing space 531. When the steel ball 11 contacts the tip of the sub-teeth 53 of the toothed structure 52, the steel ball 11 is pushed by the sub-teeth 53, and the spring 12 is also squeezed by the steel ball 11 and deformed. When the steel ball 11 does not contact the sub-teeth 53 or is located in the sub-teeth spacing space 531, the spring 12 is released and can recover from the deformed state. By changing the elastic potential energy of the spring 12, the steel ball 11 can cause an impact on the rotary driving body 5, so that the user has a continuous clicking feel, such as an operating feel similar to the vibration of a ratchet wrench. Thereby, the rotation process can be turned into a staged rotation, and the operator can know the speed of the rotation of the control shaft 2 through the feedback of the vibration frequency.

[0120] The present invention can also achieve the above functions through other designs. Figure 7 is an exploded view of an encoder 1 with a light emitting diode according to another embodiment of the present invention, and please also refer to Figures 1 to 6 . Figure 7 Most of the features of the embodiments are applicable Figure 1 The following is a description of the embodiments, so the differences are mainly described.

[0121] exist Figure 7 In the embodiment, the encoder 1 with a light emitting diode may not have a steel ball 11 or a spring 12, but may have an annular spring 19. The annular spring 19 may be disposed in the insulating base 10, and the rotary driving body 5 may be disposed above the annular spring 19. The annular spring 19 has at least one protrusion 19h, and the protrusion 19h may be disposed corresponding to the tooth structure 52. Therefore, when the rotary driving body 5 is not rotating, the protrusion 19h may be located in the sub-tooth spacing space 531 between adjacent sub-teeth 53, and when the rotary driving body 5 rotates, the protrusion 19h may be pushed by the sub-teeth 53 and slide to the sub-tooth spacing space 531 between another pair of adjacent sub-teeth 63. In this way, it is still possible to generate Figure 6 The steel ball 11 and the spring 12 of the embodiment have functions (such as operational feel feedback).

[0122] Furthermore, in one embodiment, if the aforementioned function such as operational feel feedback is not needed, the aforementioned related elements such as the steel ball 11, the spring 12 or the annular spring sheet 19 can be removed, or the tooth structure 52 of the rotary driving body 5 can be directly removed, but the present invention is not limited thereto.

[0123] It can be seen from this that the present invention integrates the switch module A, the encoder module B and the light-emitting diode 7 into one, which can be operated independently and have the functions of light, switch and encoder of different mixed colors. In this way, the structural design and process can be simplified to achieve the purpose of being light and thin. In addition, the encoder module B of the present invention adopts non-contact magnetic induction technology, which can greatly improve the service life. In addition, the insulating base 10 of the present invention can be provided with a steel ball 11 and a spring 12, or with an annular spring 19, which can be used with the rotating drive body 5 to provide the user with an operational feel feedback effect.

[0124] In one embodiment, the present invention can compare a product at least by means of mechanical observation, such as using the presence or absence of components or the operational relationship between components as evidence of whether the product falls within the scope of protection of the present invention, but is not limited thereto. In one embodiment, the mechanical observation can be achieved, for example, by using an optical microscope or a scanning microscope, but is not limited thereto.

[0125] By this, the present invention can be understood.

[0126] The details or features of the various embodiments of the present invention may be mixed and matched as long as they do not violate the spirit of the invention or conflict with each other. In addition, the above embodiments are only examples for the convenience of explanation, and the scope of rights claimed by the present invention shall be subject to the claims, rather than being limited to the above embodiments.
