[0035] It should be noted that in the claims and description of this patent, the terms "include", "comprises" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprises a" do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0036] like Figure 1 As shown, this embodiment discloses an electric locking device, which includes a housing 1, a motor 2, a rotating shaft 3, a transmission mechanism 4, a locking pin 5, a driving spring 6 and a fixing pin 7.

[0037] There is space for installing other devices inside the housing 1. The motor 2 is installed in the housing 1. The rotating shaft 3 is rotatably installed in the housing 1, and most of the rotating shaft 3 is located in the housing 1, and a part of the rotating shaft 3 extends out of the housing 1 and is connected to the transmission mechanism 4.

[0038] The transmission mechanism 4 is rotatably mounted outside the housing 1, and the transmission mechanism 4 connects the output shaft of the motor 2 and one end of the rotating shaft 3. In this embodiment, the transmission mechanism 4 is a gear transmission mechanism 4. In other alternative embodiments, the transmission mechanism 4 can also be a belt transmission mechanism 4, etc.

[0039] One end of the lock pin 5 ( Figure 1 The lower end of the shaft is connected to the rotating shaft 3 by sliding, and the other end ( Figure 1 The upper end of the rotating shaft 3 is exposed outside the housing 1. Specifically, the locking pin 5 of this embodiment includes a connecting portion 51 and a locking rod portion 52. The connecting portion 51 is provided with a sliding channel 511. The locking rod portion 52 is connected to the connecting portion 51. Figure 1 The upper end of the locking rod 52 is provided with a slider 8 matching the sliding channel 511, and the slider 8 is slidably arranged in the sliding channel. More specifically, the diameter of the locking rod 52 gradually decreases in the direction away from the connecting portion 51, so that the locking pin 5 can be inserted into the locking hole.

[0040] The driving spring 6 is sleeved on the rotating shaft 3, and one end of the driving spring 6 close to the transmission mechanism 4 ( Figure 1 The lower end of the spring 6 is connected to the housing 1, and the end of the drive spring 6 away from the transmission mechanism 4 ( Figure 1 The upper end of the tube is connected to the connecting portion 51.

[0041] The fixing pin 7 is mounted on the rotating shaft 3 and is located in a space corresponding to the pitch of the driving spring 6 .

[0042] In this embodiment, the fixing pin 7 and the driving spring 6 form a screw-like transmission mechanism 4, thereby converting the rotational torque into a linear pressure or tension of the spring, thereby driving the locking pin 5 to achieve a linear telescopic motion.

[0043] When the rotating seat in the riding device adopts the electric locking device of this embodiment, it can not only realize automatic control of the rotation and fixation of the seat, which is very convenient to use, but also improve the rigidity of the structure and improve the reliability of the structure.
