As shown in fig. 2A-2B, the housing assembly 102 includes a first end cap 204, a housing 202, and a second end cap 206. Specifically, the housing 202 defines a hollow portion extending through the left and right, and the first end cap 204 is provided on the left end of the housing 202 and the second end cap 206 is provided on the right end of the housing 202. First end cap 204, housing 202, and second end cap 206 collectively define a receptacle 222. A piston assembly is disposed in the cavity 222 to divide the cavity 222 into left and right cavities. A through hole 224 is formed in the second end cap 206, so that the right accommodating cavity can be communicated with the outside through the through hole 224. The piston assembly includes a needle 212, a connector 216, and a seal 214. The needle 212 is connected to a connector 216. The sealing ring 214 is annular and is fitted over the needle 212 and the connector 216. The piston assembly is disposed in the hollow portion and is movable in the hollow portion in the left-right direction. The sensing component 104 is coupled to the first end cap 204. Specifically, the sensing component 104 includes a sensing piece body 232 and a trigger 234. The trigger 234 is disposed on the sensor body 232 for contacting or separating with the needle 212. The piston assembly has a first position and a second position, with the needle 212 contacting the trigger 234 when the piston assembly is in the first position, and with the needle 212 being separated from the trigger 234 when the piston assembly is in the second position.

As shown in fig. 2A-2B, the damping assembly 100 further includes an elastic member 219 and a force applying member 218. A resilient member 219 is disposed in the right receptacle and is capable of abutting between the second end cap 206 and the piston assembly to provide a force for movement of the piston assembly from the second position to the first position. In the example of the present application, the elastic member 219 is a spring. The urging member 218 has a rod shape. The force applying member 218 is connected to the piston assembly at one end and is free at the other end. Specifically, one end of the force application member 218 is connected to the connecting member 216 of the piston assembly, and the other end thereof can extend out of the right receiving cavity through the through hole 224 of the second end cap 206 to be connected to the moving member.

Fig. 3 is a perspective view of needle 212 shown in fig. 2A. As shown in fig. 3, needle 212 includes a circular plate 302, a needle portion 304, and a connecting end 306. The circular sheet 302 is a substantially circular sheet. The needle portion 304 and the connecting end 306 are disposed on both sides of the circular piece 302. The left end of the needle portion 304 is a free end, and the right end is used for connecting with the left side of the circular piece 302. The left end of the needle portion 304 can be in contact with or separated from the trigger portion 234. The connecting end 306 is adapted to connect to the connector 216. The right side of the circular plate 302 is provided with a vent groove 308 formed by being depressed leftward from the surface of the circular plate 302 and extending to the outer periphery of the circular plate 302 in the radial direction of the circular plate 302.

Specifically, the outer perimeter of the first portion 402 of the connector is generally annular and has an outer diameter that is substantially the same as the outer diameter of the circular plate 302. Connector first portion 402 is capable of receiving connecting end 306 such that needle 212 is connected to connector 216. The second connector portion 404 is attached to the right of the first connector portion 402. The second portion 404 of the connector has a hole 406 for receiving the left end of the force applying member 218, thereby connecting the second portion 404 of the connector with the force applying member 218.

Fig. 5 is a perspective view of the damping assembly 100 shown in fig. 1A without the housing 202 shown. As shown in fig. 5, the seal 214 is fitted over the connected needle 212 and connector 216. The outer circumference of the sealing ring 214 is sized to match the inner wall of the hollow of the housing 202 so that the pocket 222 can be divided into left and right pockets when the piston assembly is disposed in the hollow. It can be seen from fig. 5 that when the components of the piston assembly are assembled and held in place, the seal 214 does not completely cover the vent slot 308, although it fits over the needle 212 and connector 216. The left and right plenums can communicate through a vent slot 308.

Fig. 6 is a perspective view of the first end cap 204 shown in fig. 2A-2B. As shown in fig. 6, the first end cap 204 is substantially pen-cap shaped and is configured to fit over the left end of the housing 202. First end cap 204 defines a needle-like cavity formed extending inwardly from the right side of first end cap 204 for receiving needle 212. The circumferential wall of the first end cap 204 is provided with an opening 602 to receive at least a portion of the trigger portion 234 of the sensing member 104 to allow the needle 212 to contact the trigger portion 234. In the present application, trigger 234 is made of a deformable material (e.g., rubber, etc.) and is configured such that at least a portion of trigger 234 is received in the needle-like cavity when trigger 234 is not compressed by needle 212.

FIG. 7A is a cross-sectional view of the piston assembly in the damping assembly 100 shown in FIG. 1A in a first position, and FIG. 7B is a cross-sectional view of the piston assembly in the damping assembly 100 shown in FIG. 1A in a second position. As shown in fig. 7A, when the piston assembly is in the first position, the piston assembly is generally located at the left end of the cavity 222. The trigger 234 is pressed by the needle 212 of the piston assembly to be deformed. The needle 212 of the piston assembly contacts the trigger 234. As shown in FIG. 7B, when the piston assembly is in the second position, the needle 212 of the piston assembly is disengaged from the trigger 234. Trigger 234 is not compressed by needle 212 of the piston assembly and returns to its original shape (i.e., at least a portion of trigger 234 is received in cavity 222).

The damping and return effects of the damping assembly 100 are described below in connection with fig. 7A-7B. As one example, the free end of the force applying member 218 of the damping assembly 100 is coupled to a moving object. The moving object receives an external force and is movable between a start position and an end position with respect to the housing 202 in a length direction (i.e., left-right direction) of the hollow portion of the housing 202. When the moving object is in the starting position, the piston assembly of the damping assembly 100 is in the first position; when the moving object is in the end position, the piston assembly of the damping assembly 100 is in the second position. As the moving object moves from the starting position toward the ending position (i.e., away from the housing 202), the damping assembly 100 moves the piston assembly from the first position to the second position. On the one hand, because moving object drives piston assembly and moves to the right, consequently the volume that holds the chamber on the left side can the grow, and left side chamber and right side chamber rely on the air channel 308 on circular sheet 302 to be linked together, and the size of air channel 308 is very little, and consequently the air that holds the chamber on the right side gets into the speed that holds the chamber on the left side is lower, thereby hinders moving object drive piston assembly and keeps away from casing 202 motion. On the other hand, when the piston assembly moves from the first position to the second position, the resilient member 219 is compressed, and the compression of the resilient member 219 generates a force that resists movement of the piston assembly away from the housing 202. Thus, the damping assembly 100 of the present application is capable of reducing the speed of movement of a moving object away from the housing 202. In addition, when the moving object moves to the end position and the moving object is not subjected to an external force, the compressed elastic member 219 applies a leftward force to the piston assembly, so that the piston assembly moves from the second position to the first position to drive the moving object to move from the end position toward the start position until the piston assembly returns to the first position and contacts the trigger 234.

In this application, "second position" refers to the position of the piston assembly when the piston assembly is separated from the sensing member 104. The piston assembly in the "second position" may be located in a middle position of the cavity 222 or may be located at a right end of the cavity 222. Fig. 7B shows only one state diagram of the piston assembly in the "second position".

The damping assembly 100 of the present application is capable of detecting the position of a moving object while damping the moving object. This arrangement is particularly suitable for objects with complex motion trajectories. The structure is simple and the assembly is convenient.

FIG. 8 is a system diagram of a damping assembly system 800 using the damping assembly shown in FIG. 1A. As shown in fig. 8, the damping assembly system 800 includes the damping assembly 100, a control device 801, and an output device 802. The sensing component 104 in the damping assembly 100 is communicatively coupled to the control device 801 via a connection 811 and is configured to: when the needle 212 contacts the trigger 234 of the sensing part 104, the sensing part 104 sends a sensing signal to the control device 801; and when the needle 212 is separated from the trigger 234, the sensing part 104 does not send a sensing signal to the control device 801. The output device 802 may be a screen, a light device, a sound device, etc. The control device 801 is communicatively coupled to the output device 802 and configured to: when the control device 801 receives the sensing signal transmitted by the sensing part 104, the control device 801 sends an output signal to the output device 802 to control the output device 802. Thus, the user may know via the output device 802 that the piston assembly is in the first position or the second position.

Fig. 9 is a schematic internal configuration diagram of the control device 801 in fig. 8. As shown in fig. 9, the control device 801 includes a bus 902, a processor 904, an input interface 908, an output interface 912, and a memory 918 having a control program. The various components of the control device 801, including the processor 904, the input interface 908, the output interface 912, and the memory 918, are communicatively coupled to the bus 902 such that the processor 904 may control the operation of the input interface 908, the output interface 912, and the memory 918. In particular, memory 918 is used to store programs, instructions, and data, and processor 904 reads the programs, instructions, and data from memory 918 and can write data to memory 918. Processor 904 controls the operation of input interface 908 and output interface 912 by executing programs and instructions read by memory 918. As shown in fig. 9, the output interface 912 is communicatively coupled to the output device 802 via a connection 812. The input interface 908 receives the sensing signals of the sensing component 104 via the connection 811. By executing programs and instructions in memory 918, processor 904 controls the operation (e.g., turning on and off) of output device 802.

As one example, the damping assembly system 800 of the present application is employed in a vehicle. For example, a front of a rider of the vehicle is disposed with a storage assembly. The storage assembly comprises a storage shell and a storage door. The storing appearance chamber is prescribed a limit to the storing casing, offers the storing opening towards vice driving on the storing casing to the storing door can move for the storing casing, thereby opens or closed storing opening. The free end of the force application member 218 of the damping assembly 100 of the present application is connected to the stowage door and is configured to: when the storage door closes the storage opening, the piston assembly coupled to the force applying member 218 is in the first position; and the piston assembly coupled to the force applying member 218 is in the second position when the storage opening is open. Further, the output device 802 in the damping assembly system is a lamp disposed in the storage volume and configured to: when the sensing part 104 sends a signal to the control device 801, the control device 801 controls the lamp to turn on to emit light; and when the sensing part 104 does not transmit a sensing signal to the control device 801, the control device 801 controls the lamp to turn off. Thus, with the damping assembly system 100 of the present application, when a person sitting on a rider opens the storage door, the storage compartment is illuminated so that the person sitting on the rider views the storage compartment. When a person sitting on the assistant driver closes the storage door, the lamp is turned off. The arrangement not only saves energy, but also can inform personnel sitting on the assistant driver whether the storage door is closed or not through the opening and closing states of the lamp.
