[0044] In order to explain the technical content, structural features, achieved objectives and effects of the present application in detail, the following is a detailed description in conjunction with the implementation methods and the accompanying drawings.

[0045] See also Figures 1 to 7The embodiment of the present application discloses an anti-pinch device 100, which includes a first anti-pinch detection module 11, a wireless signal transmitter 12 and a controller 13. The first anti-pinch detection module 11 is connected to the wireless signal transmitter 12, and the wireless signal transmitter 12 is wirelessly connected to the controller 13. The first anti-pinch detection module 11 is configured to perform anti-pinch detection and transmit an anti-pinch detection signal to the wireless signal transmitter 12. The wireless signal transmitter 12 is configured to receive the anti-pinch detection signal and wirelessly send the anti-pinch detection signal to the controller 13. The controller 13 is configured to output a control signal according to the anti-pinch detection signal.

[0046] The anti-pinch device 100 of the embodiment of the present application includes a wireless signal transmitter 12, a first anti-pinch detection module 11 is connected to the wireless signal transmitter 12, and the wireless signal transmitter 12 is wirelessly connected to the controller 13. The anti-pinch detection signal of the first anti-pinch detection module 11 is first transmitted to the wireless signal transmitter 12, and then wirelessly sent to the controller 13 through the wireless signal transmitter 12. The first anti-pinch detection module 11 does not need to be directly connected to the controller 13 through wires, which is particularly suitable for situations where it is inconvenient to wire between the first anti-pinch detection module 11 and the controller 13 or the wires arranged are easily broken by clamping, etc., effectively solving the problems of inconvenient wiring or damage to the wires due to clamping, which easily leads to anti-pinch failure, and is conducive to the reliable execution of the anti-pinch function of the equipment with the anti-pinch device 100.

[0047] Figures 1 to 6 Different examples of a first anti-pinch detection module 11 connected to a wireless signal transmitter 12 are provided. It is understandable that in the embodiment of the present application, there may be more than one first anti-pinch detection module 11 connected to the same wireless signal transmitter 12. In the embodiment of the present application, a single anti-pinch detector 110 or a group of anti-pinch detectors 110 having a connection relationship is defined as an anti-pinch detection module.

[0048] Figures 1 to 3 In the example, the first anti-pinch detection module 11 includes an anti-pinch detector 110 .

[0049] Specifically, the anti-pinch detector 110 is connected to the wireless signal transmitter 12 via a connecting line 15. The length of the connecting line 15 can be set as required.

[0050] More specifically, the anti-pinch detector 110 and the wireless signal transmitter 12 are respectively provided with connectors 1102 and 121, and the two ends of the connecting line 15 are respectively provided with connectors 151 and 152. The connectors 152 and 151 at both ends of the connecting line 15 are respectively plugged into the connectors 121 and 1102 to realize the connection between the anti-pinch detector 110 and the wireless signal transmitter 12.

[0051] Specifically, the anti-pinch detector 110 is a mechanical anti-pinch detector, which is safe and reliable.

[0052] Figures 4 to 6 In the example, the first anti-pinch detection module 11 includes at least two anti-pinch detectors 110 connected end to end and connected in series, and the first anti-pinch detection module 11 is connected to the wireless signal transmitter 12 through the anti-pinch detector 110 located at one end. The use of at least two anti-pinch detectors 110 connected end to end and connected in series to form the first anti-pinch detection module 11 is particularly suitable for situations where a single long anti-pinch detector 110 cannot be used due to uneven installation positions or curved surfaces. The number of anti-pinch detectors 110 connected can be set according to the actual scenario. In addition, the first anti-pinch detection module 11 can be used as a single independent product for easy installation. It can be installed before leaving the factory as needed, or it can be installed by yourself.

[0053] Specifically, the anti-pinch detector 110 located at one end of the first anti-pinch detection module 11 is connected to the wireless signal transmitter 12 via a connecting line 15. The length of the connecting line 15 can be set as needed.

[0054] More specifically, the anti-pinch detector 110 and the wireless signal transmitter 12 are respectively provided with connectors 1102 and 121, and the two ends of the connecting line 15 are respectively provided with connectors 151 and 152. The connectors 152 and 151 at both ends of the connecting line 15 are respectively plugged into the connectors 121 and 1102 to realize the connection between the anti-pinch detector 110 and the wireless signal transmitter 12.

[0055] Specifically, adjacent anti-pinch detectors 110 are connected by connecting wires 15. Since adjacent anti-pinch detectors 110 are connected by connecting wires 15, it is convenient to adjust the position so as to be applied to uneven and irregular installation surfaces. The length of the connecting wires 15 can be set as needed.

[0056] More specifically, adjacent anti-pinch detectors 110 are provided with connectors 1101 and 1102 respectively, and connectors 151 and 152 are provided at both ends of the connecting line 15 respectively. The connectors 152 and 151 at both ends of the connecting line 15 are respectively plugged into the connectors 1101 and 1102 to realize the connection of adjacent anti-pinch detectors 110.

[0057] It is understandable that, in order to facilitate production and quick assembly, each anti-pinch detector 110 can be the same product, and each anti-pinch detector 110 is provided with connectors 1101 and 1102. Of course, this is not limited to this.

[0058] exist Figures 4 to 6In the example, the multiple anti-pinch detectors 110 of the first anti-pinch detection module 11 are connected end to end to form a long strip, which is convenient for arrangement along a plane. Of course, the anti-pinch detectors 110 are not limited to being connected in the above-mentioned long strip, and can be arranged as needed. For example, adjacent anti-pinch detectors 110 can be staggered to adapt to uneven surfaces. In addition, the anti-pinch detectors 110 can be designed specifically as needed. For example, the setting position of the connector can be set at different positions as needed.

[0059] It should be noted that when the first anti-pinch detection module 11 includes at least two anti-pinch detectors 110, the specific connection method and arrangement method between the anti-pinch detectors 110 are not limited, and each anti-pinch detector 110 of the first anti-pinch detection module 11 can send a signal to the wireless signal transmitter 12.

[0060] In some embodiments, the first anti-pinch detection module 11 can be selectively connected to the wireless signal transmitter 12 or the controller 13. That is, when the first anti-pinch detection module 11 is connected to the wireless signal transmitter 12, it can be changed to be connected to the controller 13 through the connecting line 15, and then it can be changed back to be connected to the wireless signal transmitter 12.

[0061] In addition, it is not excluded that the first anti-pinch detection module 11 is connected to the wireless signal transmitter 12 and connected to the controller 13 through the connecting line 15, that is, the first anti-pinch detection module 11 can send the signal to the controller 13 through the wireless signal transmitter 12, or directly through the connecting line 15. The signal can be sent to the controller 13 through different paths at the same time. Of course, the signal can also be sent to the controller 13 through one of the paths through settings. For example, the wireless signal transmitter 12 can be turned off, and the first anti-pinch detection module 11 only uses the connecting line 15 to send the signal to the controller 13. When necessary, the wireless signal transmitter 12 can be turned on to transmit the signal.

[0062] Specifically, the anti-pinch detector 110 is a mechanical anti-pinch detector, which is safe and reliable.

[0063] Please combine Figure 8 Specifically, the anti-pinch detector 110 is provided with a normally closed switch 1103. When the normally closed switch is pressed down, it is in the open state. It is also in the open state after failure, that is, it will be identified as the state of the clamped object so that the controller 13 can get a signal to prevent the clamping object from running in the failure state. If a normally open switch is set, there will be a signal only when the clamped object is pressed and turned on during operation. If the switch itself fails, there will be no signal to the controller 13 due to the clamped object, resulting in the clamping object running.

[0064] In a specific example, the anti-pinch detector 110 includes a fixed base 1104 and a movable upper cover 1105, a detection component and a spring 1106 are arranged between the fixed base 1104 and the movable upper cover 1105, and the detection component includes a normally closed switch 1103 and connectors 1101 and 1102 located at both ends of the anti-pinch detector 110, and a signal path is formed between the two connectors 1101 and 1102 to facilitate cascading with other anti-pinch detectors 110. The working principle of the anti-pinch detector 110 is known to those skilled in the art and will not be described in detail here.

[0065] The present application does not limit the specific form of the anti-pinch detector 110 .

[0066] Specifically, the wireless signal transmitter 12 transmits signals via radio waves. More specifically, the wireless signal transmitter can use a frequency band of 315 MHz, 433 MHz, 2.4 GHz or 5.8 GHz for signal transmission. Fig. 9 Specifically, the wireless signal transmitter 12 is provided with a battery replacement assembly 122 and a battery 123. The battery replacement assembly 122 makes it easier to replace the battery 123. More specifically, the battery 123 can be a 2032 button battery, which adopts an ultra-low power consumption and power saving mode control, and can have an ultra-long standby time. When the battery 123 is under-voltage and the anti-pinch device 100 is at risk of failure, it can automatically send a signal to the controller 13 to lock and prompt the user, and the locking function is automatically released after the battery 123 is replaced.

[0067] Please combine Figures 10 to 15 In some embodiments, the anti-pinch device 100 further includes a second anti-pinch detection module 14, and the second anti-pinch detection module 14 is connected to the controller 13 via a connecting line 15. In this way, the first anti-pinch detection module 11 connected to the controller 13 via the wireless signal transmitter 12 and the second anti-pinch detection module 14 connected to the controller 13 via the connecting line 15 can be simultaneously set on the device as needed. For example, when the anti-pinch detection module needs to be arranged at a position where it is inconvenient to wire to the controller 13 or when the wire is easily clamped after wiring, the first anti-pinch detection module 11 can be arranged at the corresponding position and used in conjunction with the wireless signal transmitter 12. If another position where the anti-pinch detection module needs to be arranged does not encounter the above-mentioned situation of being unsuitable for wiring, the second anti-pinch detection module 14 can be set and connected to the controller 13 via the connecting line 15, which is conducive to reducing costs.

[0068] Specifically, the second anti-pinch detection module 14 includes an anti-pinch detector 110, which is provided with a connector 1102, the controller 13 is provided with a connector 131, and connectors 152 and 151 are provided at both ends of the connecting line 15. The connectors 152 and 151 are respectively plugged with the connectors 131 and 1102 to realize the connection between the anti-pinch detector 110 and the controller 13.

[0069] The second anti-pinch detection module 14 may also include an anti-pinch detector 110 or at least two anti-pinch detectors 110 . For details, please refer to the aforementioned description of the first anti-pinch detection module 11 , which will not be repeated here.

[0070] Specifically, the controller 13 is a main control module of the equipment having the anti-pinch device 100 .

[0071] The embodiment of the present application discloses a device, including the anti-pinch device 100 as described above.

[0072] In the embodiment of the present application, since the first anti-pinch detection module 11 does not need to be directly connected to the controller 13 through wires, it is particularly suitable for situations where it is inconvenient to wire or the wires arranged between the first anti-pinch detection module 11 and the controller 13 are easily broken by being clamped, etc., and the problem of anti-pinch failure caused by inconvenient wiring or damage to the wires due to clamping is effectively solved, which is conducive to the reliable execution of the anti-pinch function of the equipment with the anti-pinch device 100.

[0073] Specifically, the device is an electric sofa, an electric chair or an electric lifting table. It can be understood that the electric sofa, the electric chair or the electric lifting table are only some examples of the devices to which the anti-pinch device 100 can be applied.

[0074] Specifically, the first anti-pinch detection module 11 and the wireless signal transmitter 12 are arranged close to each other. It is understandable that in order to facilitate the connection between the first anti-pinch detection module 11 and the wireless signal transmitter 12, the two are generally arranged close to each other.

[0075] See also Figures 16 to 19 In some embodiments, the device is a seat 200, which includes a seat body 21, a telescopic power assembly 22 and a leg pad 23. The telescopic power assembly 22 is arranged on the seat body 21, and the output end of the telescopic power assembly 22 is connected to the leg pad 23 to drive the leg pad 23 to extend or retract. The leg pad 23 has a first surface 231 and a second surface 232 opposite to the first surface 231. The first surface 231 is used for leg padding, and the second surface 232 is provided with a first anti-pinch detection module 11 and a wireless signal transmitter 12. Of course, the first anti-pinch detection module 11 and / or the wireless signal transmitter 12 are not necessarily arranged on the second surface 232 of the leg pad 23, and can also be arranged in other places, as long as they can achieve the purpose of anti-pinch detection. In this embodiment, the controller 13 can send a control signal to control the telescopic power assembly 22 according to the received anti-pinch detection signal to control the leg pad 23 to stop or reverse movement, thereby reducing the possibility of the leg pad 23 clamping objects such as people, animals or articles during movement, and avoiding damage to the seat 200.

[0076] See also Figure 20 to Figure 22In another embodiment of the present application, the device is a seat 200, and the seat 200 includes a base 24, a seat body 21, and a rising power assembly 25. The rising power assembly 25 is arranged on the base 24, and the output end of the rising power assembly 25 is connected to the seat body 21 to make the seat body 21 stand up or reset. The first anti-pinch detection module 11 and the wireless signal transmitter 12 are arranged on the seat body 21. When the user stands up, the seat body 21 needs to be reset. At this time, objects may be clamped in the area below the seat body 21, and the controller 13 can control the rising power assembly 25 to stop or reverse the movement of the seat body 21 according to the received anti-pinch detection signal, thereby reducing the possibility of the seat body 21 clamping objects such as people, animals or articles during movement, and avoiding damage to the seat 200. Specifically, the first anti-pinch detection module 11 is arranged at the bottom of the seat body 21.

[0077] More specifically, the seat 200 includes two side panels 26 and a back panel 27, and the bottom walls of the two side panels 26 and the bottom wall of the back panel 27 are respectively provided with first anti-pinch detection modules 11, and at least one of the first anti-pinch detection modules 11 on the two side panels 26 and the back panel 27 is connected to the wireless signal transmitter 12. It should be explained that each first anti-pinch detection module 11 here can be connected to the same wireless signal transmitter 12, or can be connected to different wireless signal transmitters 12. In addition, it can also be partially connected to the controller 13 through a connecting line 15, etc., which can be set according to the specific situation and is not limited here. For the convenience of connection, different first anti-pinch detection modules 11 can be connected to the controller 13 through different paths.

[0078] Specifically, the first anti-pinch detection module 11 is composed of at least two anti-pinch detectors 110 connected end to end in series and arranged along the length direction of the bottom wall of the side panel 26 or the bottom wall of the back panel 27. This arrangement is particularly suitable for situations where the bottom wall of the side panel 26 or the bottom wall of the back panel 27 is uneven or curved, which is not suitable for arranging a single long anti-pinch detector 110. This is convenient for more comprehensive coverage of the area below the seat body 21 when standing up in this situation, which is conducive to better anti-pinch, but of course not limited to this. The number of connections of the anti-pinch detector 110 can be set according to the actual scenario. Exemplarily, according to the situation, a single anti-pinch detector 110 can be set on the bottom wall of the side panel 26, and at least two anti-pinch detectors 110 connected end to end in series can be set on the back panel 27.

[0079] Specifically, when the first anti-pinch detection module 11 is arranged on the corresponding bottom surface, the wireless signal transmitter 12 can also be arranged on the corresponding bottom surface. In a specific example, the wireless signal transmitter 12 can be arranged on the inner wall of the side plate 26 near the bottom wall, so as to avoid affecting the arrangement of the first anti-pinch detection module 11 on the bottom wall of the side plate 26.

[0080] Figures 16 to 19 The seat 200 is shown with Figure 20 to Figure 22 The seat 200 shown is the same seat 200 .

[0081] Specifically, the seat 200 can be equipped with a hand controller 3, a wireless remote controller 4, etc. to control the retractable power assembly 22 or the raising power assembly 25, etc.

[0082] The above disclosure is only the preferred embodiment of the present application, which certainly cannot be used to limit the scope of rights of the present application. Therefore, equivalent changes made according to the scope of the patent application of the present application are still within the scope covered by the present application.
