[0002] With the evolution of technology, current numerous electronic products, multimedia devices are provided with operation knobs on their control panels.

Meanwhile, the operation knobs can also be used as controllers of the control panels. The operation knobs correspondingly emit control signals based on the direction of the force, so that the control panels produce control effects similar to that of the user directly touching the control panels. For example, when the operation knob receives external force in the form of depression, the operation knob can generate a pressing signal, and thus the control panel correspondingly produces a "click" control effect.

[0070] The utility model in detail explains and technical content, present with the following explanation of accompanying drawing:

[0071] Please refer to Figures 1 to 3 The utility model provides a signal generating device 10, the signal generating device 10 can produce a press signal after being stressed, the stress direction of the signal generating device 10 just like Figure 5 The press signal can provide a control effect similar to cursor click for the electronic product implemented in combination.

[0072] The signal generating device 10 includes a circuit board 11, a display module 12 and a press signal generating unit 13. The circuit board 11 serves as the power provider of the signal generating device 10, and when the signal generating device 10 is implemented in combination with other electronic products, the press signal can be transmitted to the electronic product. The display module 12 obtains power from the circuit board 11 and can emit light based on the control of the circuit board 11, and more specifically, the light can be a simple light effect change or information displayed based on the control of the electronic product.

[0073] The pressing signal generating unit 13 is located above the circuit board 11 and is used to generate the pressing signal. The pressing signal generating unit 13 has a signal trigger 131, a support tube 132, and a seat 133. The signal trigger 131 is arranged on the circuit board 11 and can generate the pressing signal when triggered. Specifically, the signal trigger 131 has elastic restoring capability. When stressed, the signal trigger 131 is compressed and sends the pressing signal. When the stress is removed, the signal trigger 131 returns to its original state and stops sending the pressing signal. The sending of the pressing signal can be determined based on factory settings. The pressing signal can be sent only once within a single pressing time, or it can be sent continuously within a single pressing time. The support tube 132 is connected to the circuit board 11 and surrounds the signal trigger 131, allowing the signal trigger 131 to be arranged therein. The seat 133 faces the support tube 132 and provides a space for the display module 12 to be arranged. The seat 133 has a platform 134, a support column 135, and a plurality of limiting claws 136. The platform 134 supports the display module 12 and allows the display module 12 to be exposed on the surface of the signal generating device 10. In this way, the light emitted by the display module 12 can be observed from the outside of the signal generating device 10. The support column 135 extends from one side of the platform 134 towards the circuit board 11 and abuts against the signal trigger 131 at one end to support the platform 134. It should be noted that Figure 4 With Figure 5 the support column 135 does not compress the signal trigger 131 when not stressed, but only contacts the signal trigger 131. The support column 135 compresses the signal trigger 131 only when stressed. The plurality of limiting claws 136 are arranged on the platform 134 and can hook onto the support tube 132. The plurality of limiting claws 136 are used to maintain the connection relationship between the seat 133 and the support tube 132. In other words, when the plurality of limiting claws 136 hook onto the support tube 132, they only limit the structural connection relationship between the seat 133 and the support tube 132, and do not limit the displacement of the seat 133 relative to the support tube 132.

[0074] Continuing, please refer to Figure 4 With Figure 5The signal generating device 10 has a first state when the support 133 is stressed, and a second state when the support 133 stops being stressed. In the first state, the support 133 is displaced towards the circuit board 11, and in the displacement process, the plurality of limiting claws 136 limit the direction of movement, while the support column 135 presses the signal trigger 131, triggering the signal trigger 131 to generate the pressing signal. In the second state, the signal trigger 131 is reset, and the support column 135 is driven, the support 133 is reversely displaced by the signal trigger 131, and the support 133 is again hooked on the support pipe 132 by the plurality of limiting claws 136, and forms a connection relationship with the support pipe 132.

[0075] In actual implementation, the signal generating device 10 is in a normal state when it is not operated, and the support 133 is not stressed, so the signal generating device 10 is in the second state. Once the signal generating device 10 is pressed, the support 133 is stressed, and the signal generating device 10 is switched from the second state to the first state. When the signal generating device 10 is no longer pressed, the support 133 stops being stressed, and the signal generating device 10 is reset from the first state to the second state.

[0076] As described above, the plurality of limiting claws 136 are arranged on the carrier 134, thereby providing multi-directional assistance for the carrier 134. When the signal generating device 10 switches between the first state and the second state, the plurality of limiting claws 136 can make the structure of the signal generating device 10 more stable, solving the problem that only single-point stress can be applied in the past. Specifically, when the carrier 134 is stressed, the plurality of limiting claws 136 collectively limit the displacement direction of the carrier 134, thereby avoiding incorrect displacement of the carrier 134. When the carrier 134 stops being stressed, the plurality of limiting claws 136 are again hooked on the support pipe 132, and collectively and stably maintain the connection relationship between the carrier 134 and the support pipe 132. In addition to the foregoing, the signal generating device 10 implemented by the utility model does not affect the display of the display module 12 before and after operation.

[0077] Please refer to Figures 2 to 4 In an embodiment, the support pipe 132 has a pipe body 137 and a limiting ring 138, the pipe body 137 is fixed on the circuit board 11 and provides a space for the support column 135, and the limiting ring 138 is connected to the pipe body 137 away from the circuit board 11, and provides a space for the plurality of limiting claws 136 to be connected.

[0078] In another embodiment, please refer to Figures 2 to 4The plurality of restriction claws 136 each has an extension arm 139 extending from the carrier 134 towards the restriction ring 138 and a barb 140 connected to the extension arm 139 and connectable with the restriction ring 138. In the embodiment, the extension arm 139 is located at the outer edge of the restriction ring 138 and restricts the displacement direction of the support column 135 when the support column 135 is displaced. The displacement distance of the support column 135 required to trigger the signal trigger 131 by the support column 135 is defined as a trigger distance. The length of the extension arm 139 is consistent with the trigger distance of the support column 133, so that the displacement of the support column 133 can be guided by the extension arm 139. In another embodiment, please refer to Figure 6 The plurality of restriction claws 136 provides stable positioning and guidance of the support column 135 in multiple directions. The plurality of restriction claws 136 are evenly distributed around the circumference of the carrier 134. In the embodiment, the number of the plurality of restriction claws 136 is greater than or equal to four, and the plurality of restriction claws 136 collectively surround the support column 135, so that the plurality of restriction claws 136 can assist in stabilizing the support column 135 when the support column 135 presses the signal trigger 131.

[0079] In addition to the foregoing, the utility model is to assist the displacement of the support column 135. In an embodiment, the restriction ring 138 and the carrier 134 are respectively provided with at least one opening 141 and at least one guide column 142. The at least one guide column 142 penetrates into the at least one opening 141 and can be displaced along the at least one opening 141. In the embodiment, the at least one opening 141 is provided on the restriction ring 138, and the at least one guide column 142 is provided on the carrier 134. Figure 2 In the embodiment, the at least one opening 141 is provided on the restriction ring 138, and the at least one guide column 142 is provided on the carrier 134.

[0080] In another embodiment, the support pipe 132 has a partition plate 143 provided on the pipe body 137 and forming a through hole 144. The through hole 144 provides the support column 135 to be arranged therein and guides the displacement of the support column 135, thereby assisting in limiting the displacement of the support column 133. Further, the support pipe 132 further has a positioning auxiliary wall 145 extending from one side of the partition plate 143 and arranged around the through hole 144. The horizontal height of the positioning auxiliary wall 145 is higher than that of the partition plate 143, so as to assist in limiting the displacement of the support column 135.

[0081] As described above, in an embodiment, the signal generating device 10 has at least one sealing ring 16 provided in the pipe body 137 of the support pipe 132. The at least one sealing ring 16 is sleeved outside the support column 135 and arranged in the through hole 144, so as to provide the effect of sealing and waterproofing.

[0082] In another aspect, please refer toFigures 2 to 4 The display module 12 has at least one electrical line 121, which connects to the circuit board 11 to obtain power. The platform 134 has a through hole 146, through which the at least one electrical line 121 passes. In one embodiment, the platform 134 has a groove 147, which accommodates the at least one electrical line 121 to achieve the purpose of storing the at least one electrical line 121. In another embodiment, when the at least one electrical line 121 is implemented as a flexible flat cable, the support tube 132 has a recessed groove 148, which provides the flexible flat cable for placement to avoid the flexible flat cable interfering with the tube body 137 of the support tube 132. In addition, in this embodiment, the flexible flat cable has at least one bend 122 so that both ends of the flexible flat cable are connected to the circuit board 11 and the display module 12, respectively.

[0083] In addition, to limit the position of the display module 12 on the platform 134, in one embodiment, the platform 134 has a supporting surface 149 for supporting the display module 12, and the platform 134 forms a positioning wall 150 disposed on the supporting surface 149, the positioning wall 150 surrounding the display module 12. In another embodiment, the display module 12 has a frame 123 located on the top surface of the display module 12, opposite to the supporting surface 149. In yet another embodiment, to protect the display module 12, the signal generating device 10 has a protective cover 17, the protective cover 17 is stacked on the display module 12, the material of the protective cover 17 allows light from the display module 12 to pass through, so that the light from the display module 12 can be observed from the outside of the signal generating device 10.

[0084] In addition to the foregoing, please refer to Figure 2 , Figure 4 The signal generating device 10 of this invention further includes a rotation signal generating unit 18, which is located on the circuit board 11 and is used to generate a rotation signal. The rotation signal generating unit 18 has an encoder 181 and an operating ring 182. The operating ring 182 connects the encoder 181 to the support 133. The encoder 181 has a body 186 connected to the circuit board 11 and a rotating member 187 disposed on the body 186 and driven by the operating ring 182. The body 186 is arranged around the signal trigger member 131. The rotating member 187 is connected to the operating ring 182 and can rotate relative to the body 186 after being driven, so that the body 186 determines the output rotation signal based on the rotation angle of the operating ring 182. In actual operation, the rotation angle of the operating ring 182 can be determined by the displacement of a certain point 188.

[0085] In one embodiment, the encoder 181 is provided with the support tube 132 arranged therein, and the support tube 132 is shaped with at least one limiting rib 151, which cooperates with the encoder 181 to limit the rotation of the support tube 132 relative to the encoder 181. In another embodiment, the operation ring 182 has a platform 183, a first ring wall 184 and a second ring wall 185. The platform 183 is arranged to face the carrier 134. The first ring wall 184 is connected to the platform 183 and arranged to surround the carrier 134, and provides limiting for the carrier 134. The second ring wall 185 is connected to the first ring wall 184 and arranged to surround the protective cover 17, and provides limiting for the protective cover 17. In this embodiment, the second ring wall 185 has a height higher than that of the first ring wall 184, and the second ring wall 185 has a larger diameter than that of the first ring wall 184. It should be noted that the first ring wall 184 and the second ring wall 185 of the utility model only provide basic limiting, and are not fixedly connected to the carrier 134 and the protective cover 17. In other words, the rotation of the operation ring 182 will cause the carrier 134 and the protective cover 17 to rotate, and will not affect the display of the display module 12.
