Description

Technical Field

[0001] The present invention belongs to the technical field of button structures, and more specifically, relates to a multifunctional button structure and a robot. Background Art

[0002] Button structures are widely used in fields such as robots, terminal devices, and household appliances. When the button structure is pressed, it can control the start and stop, function switching, etc. of the corresponding device. At the same time, electrical devices such as robots, terminal devices, and household appliances are not only provided with button structures, but some are also provided with sensing components, signal lights, etc., which results in a large occupied device space. Especially when applied to small robots, it will cause excessive occupation of the robot layout space. Summary of the Invention

[0003] The purpose of the embodiments of the present invention is to provide a multifunctional button structure and a robot to solve the technical problem of excessive space occupied by button structures, sensing components, signal lights, etc. in the prior art.

[0004] To achieve the above object, the technical solution adopted by the present invention is: providing a multifunctional button structure, including:

[0005] A main housing having a button hole;

[0006] A main circuit board fixed to the main housing, and a switching device is fixedly and electrically connected to the main circuit board;

[0007] A button housing disposed at the button hole and above the switching device to drive the switching device to conduct or disconnect;

[0008] A sensor, at least part of which is received in the button housing; and

[0009] A light source disposed adjacent to the peripheral wall of the button hole and electrically connected to the main circuit board;

[0010] The button housing is provided with a first light-transmitting area opposite to the sensor;

[0011] A second light-transmitting area for the light source to emit light is provided between the main housing and the button housing, on the main housing or on the button housing.

[0012] In the above solution, the multi-functional button structure includes a main housing, a main circuit board, a button housing, a sensor, and a light source. The button housing is used to drive a switching device on the main circuit board. At least part of the sensor is disposed inside the button housing, and inductive detection can be performed through a first light-transmitting area on the button housing. At the same time, the light source is also adjacent to the button housing. In this way, the switching device, the sensor, and the light source are integrated in the same area, minimizing the space occupied by the above components as much as possible, forming a three-in-one multi-functional button structure, which can reserve more sufficient layout space for other components of the robot.

[0013] Optionally, the button housing includes a button outer shell for pressing and a button inner shell for triggering the switching device. The button inner shell is opposite to the switching device. At least part of the button outer shell protrudes away from the switching device. The sensor is located between the button outer shell and the button inner shell.

[0014] In the above solution, by setting the button housing as the button outer shell and the button inner shell, first, enough space is formed inside the button housing to accommodate the sensor, and second, the processing and manufacturing of the button housing are made easier, and the assembly between the button housing and the sensor is also simpler.

[0015] Optionally, the button outer shell includes a light-transmitting housing and an angle-limiting housing that are fixedly connected. The angle-limiting housing is cylindrical. At least the transmitting and receiving parts of the sensor extend into the angle-limiting housing. The angle-limiting housing has a light-blocking surface on the side away from the button inner shell. The first light-transmitting area is located on the light-transmitting housing.

[0016] In the above solution, by setting the button outer shell as the light-transmitting housing and the angle-limiting housing, first, the sensor can be circumferentially limited by the angle-limiting housing to prevent the sensor from shaking when the button housing is pressed, and second, the light-transmitting housing and the angle-limiting housing can be formed separately, and the materials and colors of the two are different, respectively meeting the light-transmitting function and the light-blocking function.

[0017] Optionally, the main housing includes an annular housing disposed on the outer periphery of the button outer shell. The outer periphery of the angle-limiting housing protrudes radially outward to form a first annular protrusion. One end of the light-transmitting housing close to the angle-limiting housing protrudes radially outward to form a second annular protrusion. The inner peripheral wall of the annular housing has an annular step. The first annular protrusion and the second annular protrusion are in mutual contact, and the annular step cooperates with the second annular protrusion to limit the button outer shell in the pressing direction.

[0018] In the above solution, through the setting of the annular housing, the positioning of the button outer shell in the pressing direction is realized, making the overall multi-functional button structure more stable.

[0019] Optionally, the light source includes a light source circuit board and a light-emitting component disposed on the light source circuit board. The light source circuit board is electrically connected to the main circuit board, and the light-emitting component is annularly disposed on the outer periphery of the key housing.

[0020] In the above solution, by annularly disposing the light-emitting component on the outer periphery of the key housing, the light source can be close to the key housing, making full use of the space around the key housing, so that the integration of the multifunctional key structure is higher and the occupied space is smaller.

[0021] Optionally, the main housing includes a base shell and an annular shell. The annular shell has the key hole, and a second light-transmitting area is formed between the base shell and the annular shell. The light-emitting component is disposed opposite to the second light-transmitting area.

[0022] In the above solution, the main housing is divided into a base shell and an annular shell, so that the main housing has a second light-transmitting area for light to exit, and then the light-emitting component is annularly arranged on the outer periphery of the key housing. While not affecting the internal layout of the key housing, the occupied space can be reduced as much as possible.

[0023] Optionally, a Fresnel lens is disposed at the second light-transmitting area.

[0024] In the above solution, the Fresnel lens has Fresnel lines. After the light emitted by the light-emitting component passes through the Fresnel lens, it has a better focusing effect, making the intensity of the emitted light higher.

[0025] Optionally, the sensor is fixed and electrically connected to a sensing circuit board. The inner key housing is disposed on the side of the sensing circuit board opposite to the sensor, and the sensing circuit board is electrically connected to the light source circuit board.

[0026] In the above solution, the sensor and the light-emitting component are respectively disposed on the sensing circuit board and the light source circuit board, and the two are electrically connected to each other and share the same main circuit board, which can reduce the usage of circuit boards, reduce the volume, and make it easier to integrate the sensor, the key, and the light source.

[0027] Optionally, the light source circuit board is annularly disposed around the sensing circuit board. At the connection part of the sensing circuit board and the light source circuit board, the length of the connection part is greater than the distance between the sensing circuit board and the light source circuit board, so that the sensing circuit board can move relative to the light source circuit board in the pressing direction.

[0028] In the above solution, when an external force presses the key housing, the sensing circuit board and the sensor will move synchronously with the key housing. By making the connection part longer (greater than the distance between the sensing circuit board and the light source circuit board), the movement of the sensing circuit board will not affect the light source circuit board, and the light source circuit board and the light-emitting component thereon can still remain stationary.

[0029] The present invention also provides a robot, including the above-mentioned multifunctional button structure.

[0030] In the above solution, the sensor is arranged inside the button housing, and induction detection can be performed through the first light-transmitting area on the button housing. At the same time, the light source is also adjacent to the button housing. In this way, the switching device, the sensor, and the light source are integrated in the same area, minimizing the space occupied by the above components as much as possible, forming a three-in-one multifunctional button structure, which can reserve more sufficient layout space for other components of the robot.

[0031] Optionally, the robot includes a voice module. When the sensor detects that a detected object is approaching, the voice module of the robot outputs voice.

[0032] Optionally, the robot further includes a camera. When the sensor detects that a detected object is approaching, the camera is turned on and detects whether there is a user. If the camera detects a user, the voice module outputs voice. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clear and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0043] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0045] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "a plurality of" means two or more, unless otherwise specifically defined.

[0046] The button structure is widely used in fields such as robots, terminal devices, and household appliances. When the button structure is pressed, it can control the start and stop, function switching, etc. of the corresponding device. At the same time, electrical devices such as robots, terminal devices, and household appliances are not only provided with a button structure, but some are also provided with sensing components, signal lights, etc., which results in a large occupied device space. Especially when applied to small robots, it will cause excessive occupation of the robot layout space.

[0047] In order to alleviate or solve the above technical problems, the present invention proposes a multifunctional button structure and a robot. The multifunctional button structure proposed by the present invention can be applied to educational robots, service robots, etc., and can also be adapted to other household appliances, terminal electronic devices, etc. The multifunctional button structure includes a main housing 10, a main circuit board 30, a button housing 20, a sensor 40, and a light source 50. The button housing 20 can drive the switching device 31 on the main circuit board 30 to achieve the conduction or disconnection of the switching device 31. At least part of the sensor 40 is received in the button housing 20. By providing a first light-transmitting area 101 on the button housing 20, the sensing detection function of the sensor 40 can be realized. By arranging the light source 50 near the button housing 20, functions such as light emission and signal light can be realized. In this way, the button, the light source 50, and the sensor 40 can be integrated in the same structural area to form a three-in-one multifunctional structural area, reducing the space occupied by the above functional components.

[0048] The multifunctional button structure provided by the embodiments of the present invention will now be described.

[0049] Please refer to Figures 1 to 4 together, the multifunctional button structure includes:

[0050] A main housing 10 having a button hole 121;

[0051] A main circuit board 30 fixed to the main housing 10, and the main circuit board 30 is connected with a switching device 31;

[0052] A button housing 20 disposed at the button hole 121 and located above the switching device 31 to drive the switching device 31 to conduct or disconnect;

[0053] A sensor 40, at least part of which is received in the button housing 20; and

[0054] A light source 50 disposed adjacent to the peripheral wall of the button hole 121 and electrically connected to the main circuit board 30;

[0055] The button housing 20 is provided with a first light-transmitting area 101, and the main housing 10 or the button housing 20 is provided with a second light-transmitting area 102 for the light source 50 to emit light.

[0056] The main housing 10 is a housing structure for a multi-functional button structure. Structures such as the main circuit board 30 are fixed to the main housing 10. A button hole 121 is formed in the main housing 10. The button housing 20 is disposed at the peripheral wall of the button hole 121. When the button housing 20 is pressed, the main housing 10 remains in a fixed state. It should be noted that the button hole 121 can be a circumferentially closed hole, and the shape of the hole can be circular, square, etc. The button hole 121 can also be a circumferentially unclosed hole, such as a hole with a circumferential notch. That is to say, in the circumferential direction of the button housing 20, only a part of the button housing 20 cooperates with the button hole 121.

[0057] The main circuit board 30 has circuit traces. The switch device 31 is fixed and electrically connected to the main circuit board 30. When the switch device 31 is pressed and triggered, the main circuit board 30 will receive a signal that the switch device 31 has been triggered and issue a corresponding instruction according to the trigger signal. The switch device 31 can be a device commonly used, which can be pressed and triggered. The function of the switch device 31 is not limited here and can be a power switch, an indicator light switch.

[0058] The button housing 20 is the housing pressed when triggering the switch device 31. The button housing 20 is disposed at the button hole 121. It can be understood that at least a part of the button housing 20 is located within the button hole 121 to press the switch device 31. The button housing 20 will move in the pressing direction when pressed to press the switch device 31. However, during the pressing process, the main housing 10, the main circuit board 30, etc. remain in an immovable state. The button housing 20 has a first light-transmitting area 101 for the sensor 40 to emit and receive light. The main housing 10 or the button housing 20 has a second light-transmitting area 102 for the light source 50 to emit light. That is to say, the light emitted by the light source 50 can be emitted between the main housing 10 or the button housing 20.

[0059] The sensor 40 is disposed inside the button housing 20 and can emit and receive light through the first light-transmitting area 101 of the button housing 20. The sensor 40 can be a photoelectric sensor. The light source 50 is disposed adjacent to the button hole 121, and can be located within the area corresponding to the button hole 121 or slightly exceed the area corresponding to the button hole 121. The light source 50 can emit light. Among them, the light source 50 can be used as an indicator light.

[0060] The multi-functional button structure in the above embodiments includes a main housing 10, a main circuit board 30, a button housing 20, a sensor 40, and a light source 50. The button housing 20 is used to drive a switching device 31 on the main circuit board 30. The sensor 40 is disposed inside the button housing 20 and can perform induction detection through a first light-transmitting area 101 on the button housing 20. At the same time, the light source 50 is also adjacent to the button housing 20. In this way, the switching device 31, the sensor 40, and the light source 50 are integrated in the same area, minimizing the space occupied by the above components as much as possible, forming a three-in-one multi-functional button structure, and leaving more sufficient layout space for other components of the robot.

[0061] In some embodiments of the present invention, the sensor 40 is an infrared photoelectric sensor, which can detect whether a person is approaching the robot. Specifically, the infrared photoelectric sensor includes a transmitting part and a receiving part. The transmitting part emits infrared light. After a person or an object approaches, at least part of the infrared light is blocked and forms a reflected light that is received by the receiving part. Therefore, it can detect whether a person or an object is approaching.

[0062] In some embodiments of the present invention, when the sensor 40 detects that an object or a person is approaching, the detection signal is fed back to the main circuit board 30, and the main circuit board 30 can control the camera to turn on and take pictures of the person or object approaching the robot.

[0063] In some embodiments of the present invention, the first light-transmitting area 101 and the second light-transmitting area 102 may be provided with light-transmitting or semi-light-transmitting light-transmitting structures, such as glass, transparent plastic plates, etc.

[0064] In some embodiments of the present invention, please refer to Figures 3 to 5 , the button housing 20 includes a button outer shell 21 for pressing and a button inner shell 22 for triggering the switching device 31. The button inner shell 22 faces the switching device 31. Preferably, the button inner shell 22 is in contact with the switching device 31. The button outer shell 21 protrudes in a direction away from the switching device 31 and at least part of it is exposed. The sensor 40 is located between the button outer shell 21 and the button inner shell 22. At least part of the button outer shell 21 is exposed. The button outer shell 21 receives the pressure of external pressing. The button inner shell 22 is located inside the multi-functional button structure. Preferably, the button inner shell 22 is in contact with the switching device 31. When triggering the switching device 31, the button outer shell 21 receives the pressure pressed by the user, and the button outer shell 21 drives the sensor 40 and the button inner shell 22 to move together in the pressing direction, and then triggers the switching device 31 through the button inner shell 22. Among them, since part of the button outer shell 21 is exposed and the button inner shell 22 is disposed inside the main housing 10, the first light-transmitting area 101 corresponding to the sensor 40 is provided on the button outer shell 21.

[0065] By setting the button housing 20 as the button outer shell 21 and the button inner shell 22, first, sufficient space is formed inside the button housing 20 to accommodate the sensor 40, and second, the processing and manufacturing of the button housing 20 are made easier, and the assembly between the button housing 20 and the sensor 40 is also simpler.

[0066] In some embodiments, refer to Figure 3 , on the side of the button inner shell 22 facing the switch device 31, there is a pressing protrusion 221 extending towards the switch device 31. In this way, when the button inner shell 22 triggers the switch device 31, the pressing protrusion 221 contacts the switch device 31, and the switch device 31 is more easily triggered.

[0067] In some embodiments, a resilient member is further provided between the switch device 31 and the button inner shell 22. After the button inner shell 22 touches the switch device 31 under an external force and the external force disappears, the resilient member will push the button inner shell 22 and the button outer shell 21 back to the initial position. Optionally, the resilient member can be a spring.

[0068] In some embodiments, refer to Figures 3 to 5 , the button outer shell 21 includes a light-transmitting housing 211 and an angle-limiting housing 212 fixedly connected. The angle-limiting housing 212 is cylindrical. At least the emitting and receiving parts of the sensor 40 extend into the angle-limiting housing 212. On the side of the angle-limiting housing 212 away from the button inner shell 22, there is a light-blocking surface 2122, and the first light-transmitting area 101 is located in the light-transmitting housing 211. At least the emitting and receiving parts of the sensor 40 are located inside the angle-limiting housing 212. The emission and reception of the light of the sensor 40 are both limited by the light-blocking surface 2122, so that the angles of the emitted light and the incident light can be controlled. Moreover, the emission and reception of the light of the sensor 40 are both realized through the light-transmitting housing 211, and the light-transmitting housing 211 can allow light to pass through. In addition, the light-transmitting housing 211 is actually the exposed part of the button outer shell 21 for finger pressing.

[0069] Preferably, when installing the button outer shell 21, first, the angle-limiting housing 212 is sleeved on the outer periphery of the sensor 40, and then the light-transmitting housing 211 is covered on the angle-limiting housing 212.

[0070] By setting the button outer shell 21 as the light-transmitting housing 211 and the angle-limiting housing 212, first, the sensor 40 can be circumferentially limited by the angle-limiting housing 212 to prevent the sensor 40 from shaking when the button housing 20 is pressed, and second, the light-transmitting housing 211 and the angle-limiting housing 212 can be formed separately, and their materials and colors are different, respectively meeting the light-transmitting function and the light-blocking function.

[0071] In some embodiments, refer to Figure 3 and Figure 5, the light-blocking surface 2122 is a frustum-shaped surface, that is, the size of the light-blocking surface 2122 gradually increases in the direction away from the sensor 40, which is equivalent to a horn shape, and can better limit the light-emitting angle and the light-receiving angle of the sensor 40.

[0072] In some embodiments, the sensor 40 has a circumferential protrusion 41, and the angle-limiting housing 212 is correspondingly provided with a circumferential groove 2123. Through the mutual cooperation of the circumferential protrusion 41 and the circumferential groove 2123, after the angle-limiting housing 212 is sleeved on the outer periphery of the sensor 40, the angle-limiting housing 212 will not rotate circumferentially relative to the sensor 40. The number and distribution of the circumferential protrusion 41 and the circumferential groove 2123 are not limited here.

[0073] In some embodiments, the light-transmitting housing 211 can be hemispherical. First, it can make the pressing feel better. Second, it can expand the detection angle of the sensor 40 and has a light-gathering effect similar to that of a convex lens.

[0074] In some embodiments, the angle-limiting housing 212 and the light-transmitting housing 211 can be fixed by pasting, by snap-fitting, or by pressing.

[0075] In some embodiments of the present invention, please refer to Figures 3 to 5 , the main housing 10 includes an annular housing 12 disposed on the outer periphery of the button housing 21. The outer periphery of the angle-limiting housing 212 is radially outwardly protruded with a first annular protrusion 2121. One end of the light-transmitting housing 211 close to the angle-limiting housing 212 is radially outwardly protruded with a second annular protrusion 2111. The inner peripheral wall of the annular housing 12 has an annular step 122. The first annular protrusion 2121 and the second annular protrusion 2111 are in mutual abutment, and the annular step 122 cooperates with the second annular protrusion 2111 to limit the button housing 21 in the pressing direction. When installing the button housing 21, the first annular protrusion 2121 of the angle-limiting housing 212 and the second annular protrusion 2111 of the light-transmitting housing 211 are in mutual abutment to position each other in the pressing direction. When pressing the button housing 21, the second annular protrusion 2111 and the annular step 122 are separated from each other. When the external force is lost, under the elastic force of the elastic member, the second annular protrusion 2111 abuts against the annular step 122 to realize the positioning of the button housing 21 in the pressing direction.

[0076] Through the setting of the annular housing 12, the positioning of the button housing 21 in the pressing direction is realized, making the overall multi-functional button structure more stable.

[0077] In some embodiments of the present invention, please refer to Figures 3 to 6, the light source 50 includes a light source circuit board 51 and a light-emitting component 52 disposed on the light source circuit board 51. The light source circuit board 51 is electrically connected to the main circuit board 30, and the light-emitting component 52 is annularly arranged on the outer periphery of the key housing 20. The light-emitting component 52 is fixed and electrically connected to the light source circuit board 51, and the light source circuit board 51 is electrically connected to the main circuit board 30. Therefore, the light-emitting component 52 can be controlled by the main circuit board 30. Among them, the light-emitting component 52 can be an LED lamp bead or the like.

[0078] By annularly arranging the light-emitting component 52 on the outer periphery of the key housing 20, the light source 50 can be close to the key housing 20, making full use of the space around the key housing 20, so that the integration of the multifunctional key structure is higher and the occupied space is smaller.

[0079] In some embodiments, the light-emitting component 52 includes a plurality of lamp beads arranged in a circumferential ring, so that the light-emitting component 52 can be annular.

[0080] In some embodiments, the light source circuit board 51 is a flexible circuit board. The flexible circuit board with light-emitting lamp beads has a lower cost and is widely used. It can be flexibly deformed according to space limitations and is easily connected to the main circuit board 30. For example, the flexible circuit board is plugged and conducted with the main circuit board 30 through a connector terminal.

[0081] In some embodiments of the present invention, please refer to Figures 3 to 5 , the main housing 10 includes a base shell 11 and an annular shell 12. The annular shell 12 has a key hole 121. A second light-transmitting area 102 is formed between the base shell 11 and the annular shell 12, and the light-emitting component 52 is disposed opposite to the second light-transmitting area 102. The key housing 20 is disposed inside the annular shell 12. When the key housing 20 is pressed, the positions of the base shell 11 and the annular shell 12 always remain unchanged. The base shell 11 and the annular shell 12 are spaced apart, so that the light emitted by the light-emitting component 52 can be emitted through the gap between the base shell 11 and the annular shell 12. In this embodiment, it can be understood that the second light-transmitting area 102 is provided on the main housing 10. In other embodiments, the second light-transmitting area 102 can be provided on the key housing 20 or between the main housing 10 and the key housing 20.

[0082] Dividing the main housing 10 into a base shell 11 and an annular shell 12 enables the main housing 10 to have a second light-transmitting area 102 for light emission, and further enables the light-emitting component 52 to be annularly arranged on the outer periphery of the key housing 21, while not affecting the layout inside the key housing 21 and being able to minimize the occupied space as much as possible.

[0083] In some embodiments, please refer to Figure 3 and Figure 4, a Fresnel lens 60 is provided at the second light-transmitting area 102. The Fresnel lens 60 has Fresnel lines. After the light emitted by the light-emitting component 52 passes through the Fresnel lens 60, it has a better focusing effect, making the intensity of the outgoing light higher.

[0084] In some embodiments, please refer to Figure 3 and Figure 4 , the Fresnel lens 60 includes a lens barrel 63, a first stop step 61 radially extending outward from the outer wall of the lens barrel 63, and a second stop step 62 radially extending inward from the inner wall of the lens barrel 63. The first stop step 61 is used to abut against the inner peripheral wall of the base shell 11 to position the Fresnel lens 60 and the base shell 11 relative to each other, and the second stop step 62 is used to abut against the inner peripheral wall of the annular shell 12 to position the Fresnel lens 60 and the annular shell 12 relative to each other.

[0085] In some embodiments, please refer to Figure 4 , the Fresnel lens 60 has a support leg 64 extending toward the light source circuit board 51. The support leg 64 can be supported on the light source circuit board 51 or other structures, making the Fresnel lens 60 more stable after installation.

[0086] In some embodiments of the present invention, please refer to Figures 3 to 5 , the sensor 40 is fixed and electrically connected to the sensing circuit board 53. The inner key shell 22 is disposed on the side of the sensing circuit board 53 opposite to the sensor 40. The sensing circuit board 53 is electrically connected to the light source circuit board 51. The sensor 40 is electrically connected to the sensing circuit board 53, the sensing circuit board 53 is electrically connected to the light source circuit board 51, and the light source circuit board 51 is electrically connected to the main circuit board 30. Thus, the detection signal of the sensor 40 can be transmitted to the main circuit board 30. Since the sensor 40 is disposed inside the key housing 20 and fixed to the sensing circuit board 53 at the same time, the sensing circuit board 53 is disposed between the sensor 40 and the inner key shell 22.

[0087] The sensor 40 and the light-emitting component 52 are respectively disposed on the sensing circuit board 53 and the light source circuit board 51, and the two are electrically connected to each other and share the same main circuit board 30, which can reduce the usage of circuit boards, reduce the volume, and make it easier to integrate the sensor 40, the key, and the light source 50.

[0088] In some embodiments of the present invention, please refer to Figure 5 and Figure 6, the light source circuit board 51 is disposed around the circumference of the sensing circuit board 53. The connecting portion 54 of the sensing circuit board 53 and the light source circuit board 51 has a length greater than the distance between the sensing circuit board 53 and the light source circuit board 51, enabling the sensing circuit board 53 to move relative to the light source circuit board 51 in the pressing direction. The center board of the light source 50 is disposed on the outer periphery of the sensing circuit board 53, and the two are spaced apart from each other and connected to each other through the connecting portion 54. Among them, there are traces on the connecting portion 54, the light source circuit board 51, and the sensing circuit board 53, so that the sensor 40, the light-emitting element 52, and the main circuit board 30 are all electrically connected. The length of the connecting portion 54 refers to the distance from the sensing circuit board 53 to the light source circuit board 51 in the radial direction. When the length of the connecting portion 54 is greater than the distance between the sensing circuit board 53 and the light source circuit board 51, when the sensing circuit board 53 moves relative to the light source circuit board 51 in the axial direction, the connecting portion 54 has a certain length margin, so the light source circuit board 51 will not be affected by the connecting portion 54 and can still remain stationary.

[0089] When an external force presses the button housing 20, the sensing circuit board 53 and the sensor 40 will move synchronously with the button housing 20. By making the connecting portion 54 longer (greater than the distance between the sensing circuit board 53 and the light source circuit board 51), the movement of the sensing circuit board 53 can be made not to affect the light source circuit board 51, and the light source circuit board 51 and the light-emitting element 52 thereon can still remain stationary.

[0090] In some embodiments, the number of the connecting portions 54 is one. Alternatively, the number of the connecting portions 54 is multiple. When the number of the connecting portions 54 is multiple, the connection between the sensing circuit board 53 and the light source circuit board 51 is more stable and less likely to be damaged.

[0091] In some embodiments, the light source circuit board 51 is fixed to the main housing 10, so that even when the light source circuit board 51 is of a soft structure, it can maintain a stable shape and will not come into contact with other components or structures.

[0092] Please refer to Figure 1 and Figure 2 , the present invention also provides a robot, which includes the multifunctional button structure in any of the above embodiments. The robot is mainly used to assist the education of primary and middle school students.

[0093] The robot provided by the present invention adopts the above-mentioned multi-functional button structure. The multi-functional button structure includes a main housing 10, a main circuit board 30, a button housing 20, a sensor 40, and a light source 50. The button housing 20 is used to press a switching device 31 on the main circuit board 30. The sensor 40 is arranged inside the button housing 20 and can perform inductive detection through a first light-transmitting area 101 on the button housing 20. At the same time, the light source 50 is also adjacent to the button housing 20. In this way, the switching device 31, the sensor 40, and the light source 50 are integrated in the same area, minimizing the space occupied by the above components as much as possible, forming a three-in-one multi-functional button structure, and leaving more sufficient layout space for other components of the robot.

[0094] In some embodiments of the present invention, the robot further includes a camera, which is communicatively connected to the main circuit board 30. The main circuit board 30 can control the movement of the camera according to the signal detected by the sensor 40. For example, when the sensor 40 detects that a person or an object is approaching, the camera is activated to take pictures or scans of the approaching person or object.

[0095] In some embodiments of the present invention, the robot includes a voice module. In response to the sensor detecting that a detected object is approaching, the voice module of the robot outputs voice. The sensor is used to detect whether a detected object is approaching, and the detected object can be a person, an object, or other movable objects. When the sensor detects that a detected object is approaching, the detection information is uploaded to a control module such as a host computer, and the control module controls the voice module to output voice to prompt the detected object about the robot.

[0096] In some embodiments of the present invention, the robot further includes a camera. In response to the sensor detecting that a detected object is approaching, the camera is turned on and detects whether there is a user. If the camera detects a user, the voice module outputs voice. When the sensor detects that a detected object is approaching, the detection information is uploaded to a control module such as a host computer, and the control module controls the camera to turn on. When the camera detects a user, the detection information is uploaded to the control module, and the control module controls the voice module to output voice to prompt the detected object about the robot; if the control module controls the camera to turn on and the camera does not detect a user, the voice module does not output voice.

[0097] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
