The specific structure and function of the ratchet assembly 204 and the toggle assembly 206 will be described.

As shown in fig. 2 and 3, the ratchet assembly 204 includes a ratchet body 231 and four locking pins 232 and eight ratchet teeth 233 disposed on the ratchet body 231. The locking pin 232 is adapted to cooperate with the notch 121 on the locking plate 12 to lock or unlock the locking plate 12. The ratchet teeth 233 are configured to engage the lever assembly 206 such that the lever assembly 206 rotates the ratchet assembly 204. Specifically, ratchet body 231 is generally cylindrical. The rear of the ratchet body 231 is provided with a recess (not shown) for receiving the first connection 503 on the housing 202 to enable the ratchet assembly 204 to rotate relative to the housing 202. Four locking pins 232 are uniformly disposed at a first depth of the ratchet body 231 in the circumferential direction of the ratchet body 231 to mate with the notches 121 on the lock plate 12 at the same depth. The lock pin 232 is substantially rectangular and extends radially outward from the ratchet body 231. Eight ratchet teeth 233 are uniformly disposed at a second depth of the ratchet body 231 along a circumferential direction of the ratchet body 231 to mate with the second arm 302 of the shifter lever assembly 206 disposed at the same depth. The ratchet teeth 233 include a first tooth face 234 and a second tooth face 235. First tooth surface 234 is formed extending generally radially outward of ratchet body 231. Second tooth surface 235 is disposed to the right of first tooth surface 234 and is disposed at an acute angle to first tooth surface 234.

As shown in fig. 4 and 5, the ratchet assembly 204 has an unlocked position and a locked position. When the locking pin 232 in the ratchet assembly 204 is not located near the top, that is, when the locking tab 12 can be inserted into the slot 224 and contact the first arm 301, the ratchet assembly 204 is in the unlocked position. The ratchet assembly 204 is in the locked position when the lock pin 232 in the ratchet assembly 204 is located near the top, that is, when the lock plate 12 is retained in the slot 224 by the lock pin 232 after insertion into the slot 224.

In the embodiment of the present invention, the first depth of the four locking pins 232 and the second depth of the eight ratchet teeth 233 are different planes, so that the movement of the shift lever assembly 206 and the movement of the lock plate 12 do not interfere with each other.

As shown in fig. 2 and 3, the lever assembly 206 includes a first arm 301, a second arm 302, a connecting member 303, a first elastic member 304, and a second elastic member 305. The first arm 301 and the second arm 302 are rotatably connected together by a connecting member 303. Specifically, the first arm 301 has a first hole 401 at the middle for receiving the second connecting portion 504 of the housing 202, so that the first arm 301 can rotate around the second connecting portion 504 relative to the housing 202. The upper portion of the first arm 301 is provided with a protrusion for coupling with the first elastic member 304. The lower part of the first arm 301 is provided with a second hole 402 for receiving the connector 303. The upper part of the second arm 302 is provided with a third hole 403 also for receiving the connecting member 303. The connector 303 is a generally cylindrical body that is capable of passing through the second aperture 402 in the first arm 301 and the third aperture 403 in the second arm 302 to rotatably connect the first arm 301 and the second arm 302 together. The lower portion 404 of the second arm 302 is adapted to mate with eight ratchet teeth 233 on the ratchet assembly 204. When lower portion 404 of second arm 302 bears against and applies a force to first tooth surface 234, second arm 302 is able to urge ratchet assembly 204 to rotate.

As shown in fig. 2 and 3, the left end of the first elastic member 304 is connected to the upper portion of the first arm 301, and the right end of the first elastic member 304 abuts against the housing 202. In the present embodiment, the first elastic member 304 is always in a compressed state, thereby always applying a leftward force to the upper portion of the first arm 301. The first elastic member 304 may be any known elastic body, such as a spring. The second elastic member 305 is used to provide a force for the rotation of the first arm 301 and the second arm 302 toward each other. One end of the second elastic member 305 is connected to the first arm 301, and the other end of the second elastic member 305 is connected to the second arm 302. The second elastic member 305 is always in a stretched state, thereby always applying a force to the first arm 301 and the second arm 302 to rotate the first arm 301 and the second arm 302 in a direction to approach each other. The second elastic member 305 may be any known elastic body. In this embodiment, the second elastic member 305 is a torsion spring, and one end thereof is connected to the right side of the first arm 301 in a snap-fit manner, and the other end thereof is connected to the right side of the second arm 302 in a snap-fit manner.

As shown in fig. 4 and 5, the toggle assembly 206 has a first position and a second position. When the shifter assembly 206 is not subjected to a force applied thereto by the locking plate 12, the shifter assembly 206 is in the first position. The first position of the lever assembly 206 is achieved by the cooperation of the first elastic member 304, the second elastic member 305 and the guide 505. Specifically, the first elastic member 304 is in a compressed state, thereby applying a leftward force to the upper portion of the first arm 301, so that the upper portion of the first arm 301 reaches a leftmost position. The second elastic member 305 is in a stretched state, and applies a force to the first arm 301 and the second arm 302 to approach each other. The guide 505 abuts against the side of the second arm 302 so that the movement of the second arm 302 towards the first arm 301 is blocked. In this way, the toggle lever assembly 206 can remain in place in the first position. Further, the position of the shifter assembly 206 and the ratchet assembly 204 are set to: when the toggle assembly 206 is in the first position, the lower portion 404 of the second arm 302 is positioned between the two ratchet teeth 233. In the illustrated embodiment, the lower portion 404 of the second arm 302 abuts against the first tooth surface 234 of the ratchet teeth 233. When the locking plate 12 applies a force to the shifter assembly 206, the shifter assembly 206 can be in the second position. In more detail, when the locking tab 12 applies a force to the upper portion of the first arm 301 and causes the upper portion of the first arm 301 to reach the rightmost position, the lever assembly 206 is in the second position. Moreover, the shifter lever assembly 206 is further configured to: the lever assembly 206 is automatically resettable from the second position to the first position when the locking tab 12 no longer applies a force to the upper portion of the first arm 301. The process of automatically resetting the toggle lever assembly 206 from the second position to the first position will be described in detail below.

As shown in fig. 2 and 3, the pile 2 further comprises a pile sensing member 252 disposed in the housing 202. Specifically, the stake sensing member 252 is disposed above the first cavity 601 to mate with the vehicle sensing member 122 on the locking tab 12. When the locking tab 12 extends into the slot 224 and the vehicle sensing member 122 is substantially aligned with the stake sensing member 252, the stake sensing member 252 sends a stake lock status signal to the control device 3 to indicate that the vehicle 10 is locked to the stake 2.

Therefore, the utility model discloses a car stake lock device just can drive ratchet assembly 204 through driving lever assembly 206 and rotate to utilize ratchet assembly 204 to lock vehicle 10 to car stake 2 or with vehicle 10 from the unblock of car stake 2.

To more clearly describe the positional relationship of the shifter assembly 206 to the various ratchet teeth 233 during locking and unlocking, three of the eight ratchet teeth 233 are numbered in fig. 4-8, with ratchet teeth a, B, and C shown at A, B and C, respectively.

The locking process of the pile lock 13 is described below with reference to fig. 4 to 6:

as shown in fig. 4, no vehicle 10 is locked to the stub 2 at this time, and the stub lock 13 is in the unlocked state. Wherein the toggle assembly 206 is in the first position and the ratchet assembly 204 is in the unlocked position.

When the vehicle 10 needs to be locked to the pile 2, the driver pushes the vehicle 10 towards the pile 2 so that the locking tab 12 protrudes into the cavity 222 through the slot 224. With the ratchet assembly 204 in the unlocked position, the four locking pins 232 do not prevent the locking plate 12 from being inserted into the stake lock 13 and contacting the first arm 301. The locking piece 12 continues to move to the right and pushes the upper part of the first arm 301. Since the first arm 301 is rotatably fixed in the receiving cavity 222 by the second connecting portion 504, the first arm 301 is rotated in a clockwise direction about the second connecting portion 504 by the urging of the locking piece 12. The upper portion of the first arm 301 is connected to the first elastic member 304, so that the first arm 301 applies force to the first elastic member 304, thereby causing the first elastic member 304 to be compressed. The lower portion of the first arm 301 is rotatably connected to the second arm 302 by a connecting member 303. Since the guide portion 505 abuts against the side portion of the second arm 302, the second arm 302 moves downward and leftward against the guide portion 505 with the first arm 301 and the guide portion 505. The lower portion 404 of the second arm 302 moving downward and to the left bears against the first tooth surface 234 of ratchet tooth a and applies a force thereto, thereby driving the ratchet assembly 204 in a clockwise direction. The notch 121 of the locking tab 12 is always above the ratchet assembly 204 during the pushing of the first arm 301 by the locking tab 12. Thus, when the ratchet assembly 204 is rotated in a clockwise direction, the lock pin 232 in the ratchet assembly 204 rotates into the notch 121. At this point, as shown in FIG. 5, the lever assembly 206 is in the second position, the ratchet assembly 204 is in the locked position, and the vehicle 10 has been locked to the stub 2. The vehicle sensing member 122 is substantially aligned with the stake sensing member 252 and the stake sensing member 252 sends a status signal to the control device 3 indicating that the vehicle 10 is in a staked condition.

After the shifter assembly 206 is in the second position and the ratchet assembly 204 is in the locked position, the driver may remove the urging force of the vehicle 10 toward the stub 2. When the driver no longer applies force to the vehicle 10, the locking tab 12 no longer applies force to the first arm 301 and therefore the lower portion 404 of the second arm 302 no longer rotates the push ratchet assembly 204. In this way, the ratchet assembly 204 may be maintained in the locked position. Meanwhile, since the first elastic member 304 is in a compressed state, the first elastic member 304 applies a leftward force to the upper portion of the first arm 301, so that the locking piece 12 moves leftward. Although the locking plate 12 will now move a distance to the left, since the locking pin 232 is received in the recess 121, the right side edge of the recess 121 will be blocked by the locking pin 232 from further movement to the left, thereby holding the locking plate 12 in place so that the vehicle 10 is locked to the pile 2.

The automatic reset process of the lever assembly 206 from the second position to the first position when the ratchet assembly 204 is in the locked position is described below in conjunction with FIGS. 5-6:

after the shifter assembly 206 is in the second position and the ratchet assembly 204 is in the locked position, the driver may remove the urging force of the vehicle 10 toward the stub 2. When the driver no longer applies force to the vehicle 10, the locking tab 12 no longer applies force to the first arm 301. At this time, the first elastic member 304 of the lever assembly 206 in the second position is in a compressed state, and the second elastic member 305 is in a stretched state. The first elastic member 304 applies a leftward force to the upper portion of the first arm 301, and the first elastic member 304 rotates the first arm 301 in the counterclockwise direction about the second connecting portion 504 while pushing the locking piece 12 to move leftward. The second elastic member 305 and the guide portion 505 in the stretched state both exert a force on the second arm 302 to move the second arm 302 substantially to the right and upward. During movement of the second arm 302, the lower portion 404 of the second arm 302 no longer bears against the first tooth surface 234 of ratchet tooth A and rides over ratchet tooth B adjacent ratchet tooth A and eventually rests on the first tooth surface 234 of ratchet tooth B. At this point, the lever assembly 206 returns to the first position.

The process of unlocking the pile lock 13 is described below in connection with fig. 6-8:

as shown in fig. 6, the vehicle 10 is locked to the stub and the stub lock 13 is in a locked state. Wherein the lever assembly 206 is in the first position and the ratchet assembly 204 is in the locked position.

When the vehicle 10 needs to be unlocked from the pile 2, the driver pushes the vehicle 10 towards the pile 2 so that the locking tab 12 of the vehicle 10 pushes the upper part of the first arm 301. The first arm 301 is rotated in the clockwise direction about the second connecting portion 504 by the urging of the lock tab 12. The upper portion of the first arm 301 is connected to the first elastic member 304, so that the first arm 301 applies force to the first elastic member 304, thereby causing the first elastic member 304 to be compressed. The lower portion of the first arm 301 is rotatably connected to the second arm 302 by a connecting member 303. Since the guide portion 505 abuts against the side portion of the second arm 302, the second arm 302 moves downward and leftward against the guide portion 505 with the first arm 301 and the guide portion 505. The lower portion 404 of the second arm 302 moving downward and to the left bears against the first tooth face 234 of ratchet tooth B and applies a force thereto, thereby driving the ratchet assembly 204 in a clockwise direction. As the ratchet assembly 204 rotates, the lock pin 232 originally received in the notch 121 exits the notch 121, and other lock pins 232 adjacent thereto do not enter the notch 121. At this point, as shown in fig. 7, the lever assembly 206 is in the second position, the ratchet assembly 204 is in the unlocked position, and the vehicle 10 has been unlocked from the stake 2. The driver may pull the vehicle 10 away from the stake 2, thereby withdrawing the locking tab 12 from the stake lock 13. During the process of the locking plate 12 exiting the staking lock 13, the vehicle sensing member 122 on the locking plate 12 is no longer aligned with the staking sensing member 252 in the staking lock 13 and the staking sensing member 252 no longer sends a status signal to the control device 3.

The automatic reset process of the lever assembly 206 from the second position to the first position when the ratchet assembly 204 is in the unlocked position is described below in conjunction with fig. 7-8:

with the shifter assembly 206 in the second position and the ratchet assembly 204 in the locked position, the driver may pull the vehicle 10 away from the stub 2. When the driver pulls the vehicle 10 away from the pile 2, the locking tab 12 no longer exerts a force on the first arm 301. At this time, the first elastic member 304 of the lever assembly 206 in the second position is in a compressed state, and the second elastic member 305 is in a stretched state. The first elastic member 304 applies a leftward force to the upper portion of the first arm 301, so that the first arm 301 rotates in a counterclockwise direction about the second connecting portion 504. The second elastic member 305 and the guide portion 505 in the stretched state both exert a force on the second arm 302 to move the second arm 302 substantially to the right and upward. During movement of the second arm 302, the lower portion 404 of the second arm 302 no longer bears against the first tooth surface 234 of the ratchet tooth B and passes over the ratchet tooth C adjacent the ratchet tooth B and finally rests on the first tooth surface 234 of the ratchet tooth C. At this point, the lever assembly 206 returns to the first position. In other words, at this point, the shifter assembly 206 is in the first position and the ratchet assembly 204 is in the unlocked position, and the vehicle may be reinserted into the stake lock to be locked to the stake.
