Embodiment
[0042] combine Figures 1 to 7 A novel damping structure for electric tailgate struts is shown, including a sleeve 1 and a ball socket 4 fixedly connected to both ends of the sleeve 1, and the ball socket 4 is used for connecting with the automobile body and the automobile tailgate. connected, the sleeve 1 includes an outer sleeve 3 and an inner sleeve 2 telescopically connected to the outer sleeve 3;
[0043]The casing 1 is provided with a driving device 5 for driving the inner casing 2 to expand and contract relative to the outer casing 3. In this embodiment, the driving device 5 is specifically a driving motor. The driving device 5 includes an output shaft 6, an output element 8 is fixedly sleeved on the output shaft 6, and the output element 8 can rotate together with the rotation of the output shaft 6. In this embodiment, the output element 8 Specifically, a magnetic ring;
[0044] The sleeve 1 is also provided with a PCB board 7 for controlling the driving device 5, th...

The invention discloses a novel damping structure for a power liftgate supporting rod. The novel damping structure comprises a casing pipe capable of extending and shortening and ball sockets arranged at the two ends of the casing pipe, wherein a driving device is arranged in the casing pipe; the driving device further comprises an output shaft; a PCB (Printed Circuit Board) in communication connection with the driving device is arranged in the casing pipe; a sensing assembly used for sensing the number of rotation turns of the output shaft is further arranged in the casing pipe; the sensing assembly comprises an output element which is connected to the output shaft and can rotate along with the output shaft; a receiving element is arranged on the PCB; a damping assembly is further arranged in the casing pipe; the damping assembly comprises an output element and a resistance element; and the resistance element applies acting force to the output element. The damping assembly is arranged, and the damping assembly and the sensing assembly share the output element, so that the damping effect is achieved through the acting force between the resistance element and the output element; and the damping assembly and the sensing assembly share the same element, so that the internal space of the supporting rod is effectively saved, and the production cost is greatly reduced.
Description
technical field [0001] The invention relates to the field of auto parts, in particular to a novel damping structure for an electric tailgate brace. Background technique [0002] Car tailgate stays are mainly used for the opening and closing of car tailgates, and with the continuous innovation and development of automobile technology, traditional manual car tailgate stays are increasingly being replaced by electric tailgate stays, and The requirements for the electric tailgate stay are getting higher and higher. The electric tailgate stay needs to be able to hover, and it must also be able to adapt to fast manual closing. However, the existence of ordinary electric tailgate stays is caused by insufficient static internal resistance of the stay. Unable to hover, or too much force when manually closing the door causes the motor to receive too much reverse force and cause damage to the motor. Add a damper inside to increase the motor torque; [0003] In the Chinese patent appl...
