In this specification, schematic representations of the above terms do not necessarily refer to the same embodiments or examples. Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.
Referring to fig. 1 and 2, a shock absorbing device 300 according to an embodiment of the first aspect of the present invention includes a housing 310, an airbag 320, and an elastic assembly 330. The elastic assembly 330 includes an elastic element 332. The housing 310 includes a bottom case 311 and an upper cover 313, one side (refer to fig. 2, e.g., upper side) of the bottom case 311 defines a receiving groove 315, the upper cover 313 is located on the side of the bottom case 311 where the receiving groove 315 is provided, a first end (refer to fig. 2, e.g., front end) of the upper cover 313 is rotatably connected to the bottom case 311, a second end (refer to fig. 2, e.g., rear end) of the upper cover 313 is connected to the bottom case 311 through an elastic member 330, and the elastic member 332 causes the second end of the upper cover 313 to have a tendency to approach the bottom case 311.
The air bag 320 is disposed in the accommodating groove 315, the top surface of the air bag 320 abuts against the upper cover 313, and the bottom surface of the air bag 320 abuts against the bottom surface of the accommodating groove 315.
In combination with the above, when the upper cover 313 is impacted, the upper cover 313 approaches the bottom case 311, the airbag 320 is compressed, and after the impact is completed, the airbag 320 gradually resumes the deformation, so that the upper cover 313 is far away from the bottom case 311. Since the elastic element 332 makes the second end of the upper cover 313 have a tendency to approach the bottom case 311, the kinetic energy of the upper cover 313 is converted into elastic potential energy of the elastic element 332 (the elastic potential energy is finally converted into heat energy), and the rebound amplitude of the upper cover 313 is reduced. After that, when the upper cover 313 approaches the bottom case 311 again, the kinetic energy of the upper cover 313 is converted into elastic potential energy of the airbag 320 (the elastic potential energy is also converted into heat energy), and thus the kinetic energy of the upper cover 313 is repeatedly consumed, the vibration amplitude and the vibration frequency of the upper cover 313 are both reduced, and the vibration is attenuated.
Specifically, the housing 310 further includes a hinge 312, and the first end of the upper cover 313 is rotatably connected to the bottom case 311 through the hinge 312.
Referring to fig. 2, in some embodiments of the invention, the side walls of the airbag 320 include a collapsible or expandable pleated structure. Therefore, the airbag 320 is higher after being fully extended, and can be adapted to the accommodating groove 315 with a larger depth range, the top surface of the airbag 320 can be fully attached to the upper cover 313, and the bottom surface of the airbag 320 abuts against the bottom surface of the accommodating groove 315, thereby providing a stable elastic force. When the airbag 320 is inflated with different amounts of gas, the elastic force provided by the airbag 320 is also different, thereby adjusting the elastic force of the airbag 320.
The side wall includes the airbag 320 having a bellows structure, which is a multi-layered airbag.
Referring to fig. 2, in some embodiments of the present invention, the air cells 320 are provided with at least one, and at least one air cell 320 is stacked along a depth direction (referring to fig. 2, the depth direction may be an up-down direction) of the receiving groove 315. Accordingly, by increasing or decreasing the number of the air cells 320, the air cells 320 having a proper height can be stacked and filled in the accommodating groove 315, so that the top surface of the uppermost air cell 320 is completely bonded to the upper cover 313, and the bottom surface of the lowermost air cell 320 is abutted against the bottom surface of the accommodating groove 315, thereby providing a stable elastic force to the upper cover 313.
Specifically, the number of air bags 320 may be 3, 4, or other numbers, specifically selected according to the depth of the receiving groove 315.
Referring to fig. 1 and 2, in some embodiments of the present invention, the elastic assembly 330 further includes a first nut 331, a connecting piece 333, and a screw 334, the elastic element 332 is a compression spring, the connecting piece 333 is fixedly connected with the bottom shell 311, the connecting piece 333 is provided with a first through hole 337, one end of the screw 334 is fixedly connected with the second end of the upper cover 313, the other end of the screw 334 is inserted into the first through hole 337 and the compression spring, and is in threaded connection with the first nut 331, and two ends of the compression spring are respectively abutted against the connecting piece 333 and the first nut 331.
Therefore, when the upper cover 313 is far away from the bottom case 311, the screw 334 is driven to move upwards, the screw 334 drives the first nut 331 to move upwards, and the first nut 331 presses the lower end of the compression spring. Since the upper end of the compression spring is restrained by the connection piece 333 from moving upward, the compression spring is pressed, thereby giving the first nut 331 a downward elastic force which tends to approach the upper cover 313 to the bottom case 311.
In order to keep the upper cover 313 in a state of being close to the bottom case 311, the compression spring is initially in a compressed state. Further, by rotating the first nut 331, the initial compression amount of the compression spring can be changed, thereby adjusting the elastic force provided by the compression spring to a state that is adapted to the elastic force provided by the airbag 320. When the elastic force provided by the compression spring is excessively small, the vibration duration of the upper cover 313 is excessively long, and when the elastic force provided by the compression spring is excessively large, the airbag 320 is excessively compressed, and the shock absorbing effect of the airbag 320 is not good.
Specifically, the elastic assembly 330 further includes a pin 335 and a press 336. The upper cover 313 is provided with the second through-hole, and the upper end of screw 334 is provided with the third through-hole, and the upper end of screw 334 passes the second through-hole, and round pin axle 335 wears to establish in the third through-hole, and briquetting 336 passes through the fix with screw to upper cover 313, and briquetting 336 compresses tightly round pin axle 335 to be fixed in upper cover 313 with screw 334.
In addition, the screw 334 may be a stud, and the upper end of the screw 334 is screwed into one second nut, then passes through the second through hole of the upper cover 313, and finally is screwed into the other second nut at the upper end of the screw 334, and the two second nuts clamp the upper cover 313, so as to fix the screw 334 to the upper cover 313.
Referring to fig. 2, in some embodiments of the present invention, the elastic member 332 is an extension spring, one end (e.g., an upper end) of which is fixedly connected to the second end of the upper cover 313, and the other end (e.g., a lower end) of which is fixedly connected to the bottom case 311. At this time, the tension spring may directly give downward elastic force to the upper cover 313, so that the upper cover 313 has a tendency to approach the bottom case 311.
The fixed connection of the extension spring to the upper cover 313 may be achieved by a hook carried by the extension spring itself. The same applies to the fixed connection of the extension spring to the bottom shell 311.
Referring to FIG. 2, in some embodiments of the invention, an airbag 320 is provided with an air tap for inflating or deflating. Thus, the elastic force of the airbag 320 can be reduced by the deflation; by opening the air tap, the airbag 320 is inflated using an inflator or the like, thereby increasing the elastic force provided by the airbag 320.
Referring to fig. 2 to 4, fig. 3 is a schematic view of an air bag and an air pressure adjusting device of the shock absorbing device of fig. 1, and fig. 4 is a flowchart of an operation of the air pressure adjusting device 340. In some embodiments of the present invention, the shock absorbing device 300 further includes an air pressure adjusting device 340, the air pressure adjusting device 340 includes a solenoid valve 342, an inflator 343, a control unit 344, and an air pressure sensor 345, an air outlet of the inflator 343 is in communication with the air bag 320, the air pressure sensor 345 is used for feeding back an air pressure value of the air bag 320 to the control unit 344, the control unit 344 is used for controlling the inflator 343 to inflate the air bag 320, and the solenoid valve 342 is controlled to deflate the air bag 320.
Thus, a target air pressure is set to the control unit 344, when the air pressure value fed back by the air pressure sensor 345 is smaller than the target air pressure, the control unit 344 turns on the loop where the air pump 343 is located, the air pump 343 is powered on to work, and when the air pressure value fed back by the air pressure sensor 345 reaches the target air pressure, the control unit 344 turns off the loop where the air pump 343 is located, and air pressure adjustment is completed. When the air pressure sensor 345 feeds back that the air pressure value of the air bag 320 is greater than the target air pressure (the target air pressure is changed or the inflator 343 is excessively inflated), the control unit 344 opens the electromagnetic valve 342, and when the air pressure value is reduced to the target air pressure, closes the electromagnetic valve 342, thereby completing the air pressure adjustment.
Specifically, the air pressure adjusting device 340 further includes a four-way joint 341, one interface of the four-way joint 341 is communicated with the air bag 320 through an air pipe, the other three interfaces of the four-way joint 341 are respectively connected with an electromagnetic valve 342, an inflator 343 and an air pressure sensor 345, and the electromagnetic valve 342, the inflator 343 and the air pressure sensor 345 are all electrically connected with the control unit 344.
