[0045] Reference throughout the specification to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the present application. Thus, when the phrases "in one embodiment" or "in some embodiments" appear in various places throughout the specification, not all references are to the same embodiment. Furthermore, in one or more embodiments, the particular features, structures, or characteristics may be combined in any suitable manner.

[0046] See also Figures 1 to 3 , the anti-falling device provided by the present application is now described. The anti-falling device includes a support frame 1, a swing frame 3 installed on one end of the support frame 1, a turntable 4 rotatably installed on the other end of the swing frame 3, and a stop frame 5 hinged on the swing frame 3. A plurality of slots 41 for mounting the supported member 2 are provided in an annular array on the turntable 4, and each slot 41 is arranged along the radial direction of the turntable 4. A plurality of stop blocks 42 are convexly provided at intervals on the outer peripheral surface of the turntable 4. The stop frame 5 is used to abut and cooperate with the corresponding stop blocks 42, and limit the turntable 4 from rotating in the positive direction so that the supported member 2 outside is hung in the corresponding slot 41, and is used to disengage from the abutment with the corresponding stop blocks 42 when the supported member 2 pushes the turntable 4 to rotate in the reverse direction, so that the supported member 2 can escape from the corresponding slot 41.

[0047] In one embodiment, the support member 2 may be a vehicle plate hanging ring, which is not limited here. In some embodiments, the vehicle plate hanging ring may be an inverted "U"-shaped structure, so that it can be conveniently mounted in the corresponding slot 41 to achieve connection with the turntable 4.

[0048] During the process of the support member 2 rising, it can be guided to the corresponding slot 41 by the corresponding stopper block 42; during the process of the support member 2 continuing to rise, the stopper frame 5 can cooperate with the corresponding stopper block 42 to stop the turntable 4 from rotating; then the support member 2 descends and extends to the bottom of the slot 41. At this time, the turntable 4 cannot rotate because the stopper frame 5 is blocked by the corresponding stopper block 42, so that the support member 2 is mounted on the turntable 4. When the support member 2 is unloaded, the support member 2 moves up and drives the turntable 4 to rotate in the opposite direction, so that the stopper frame 5 and the corresponding stopper block 42 are unlocked, and the support member 2 can be removed from the turntable 4.

[0049] This structure is to install the turntable 4 on the swing frame 3 by rotation. The turntable 4 is provided with a plurality of slots 41 in a ring array, and the outer peripheral surface of the turntable 4 is provided with a plurality of stop blocks 42 at intervals. When the support member 2 is inserted into one of the slots 41, the stop frame 5 can cooperate with the corresponding stop block 42 to stop the turntable 4 from rotating, and the support member 2 and the turntable 4 are automatically connected and locked; when the support member 2 is removed from the slot 41, the stop frame 5 can be unlocked from the stop block 42, and the support member 2 and the turntable 4 are automatically separated. Compared with the traditional electromagnetic hook and power hook, it does not require power-assisted operation, is convenient and quick to operate, consumes less energy, and has low cost.

[0050] In one embodiment, see Figure 1 As a specific embodiment of the anti-fall device provided by the present application, a stopper 42 is provided between two adjacent slots 41; each stopper 42 has a first arc surface 421 connected to the inner side wall of an adjacent slot 41 close to the stopper 42, and a second arc surface 422 connected to the inner side wall of another adjacent slot 41 close to the stopper 42. Specifically, in two adjacent slots 41: the inner side wall of one slot 41 close to the corresponding stopper 42 extends in the direction away from the center of the turntable 4, and gradually bends a distance toward the circumference of the turntable 4 to form the above-mentioned first arc surface 421; the inner side wall of the other slot 41 close to the corresponding stopper 42 bends and extends toward the end of the first arc surface 421 away from the turntable 4 to form the above-mentioned second arc surface 422. The outer peripheral surface of the turntable 4, each first arc surface 421 and the corresponding second arc surface 422 enclose the shape of the above-mentioned stopper 42. In this structure, on the one hand, the first curved surface 421 can achieve effective cooperation and stopping with the stop frame 5; on the other hand, the first curved surface 421 can guide the supported part 2 to the corresponding slot 41; on the third hand, the first curved surface 421 on one stop block 42 cooperates with the second curved surface 422 on another stop block 42, which can achieve rapid uncoupling of the supported part 2 and the stop frame 5, thereby improving the reliability of the anti-fall device.

[0051] In one embodiment, the number of the blocking blocks 42 can be four or five, and the number of the slots 41 can be set in a one-to-one correspondence with the number of the blocking blocks 42. This structure, through experimental simulation analysis, shows that setting four or five blocking blocks 42 can achieve effective mounting and disengagement between the support member 2 and the turntable 4, without any failure points, and with high reliability. Of course, in other embodiments, the number of blocking blocks 42 and the slots 41 can be adjusted according to actual needs, and is not limited here.

[0052] In one embodiment, see Figure 1 As a specific embodiment of the anti-fall device provided by the present application, the curvature of the first arcuate surface 421 is greater than the curvature of the second arcuate surface 422. Specifically, the curvature of the first arcuate surface 421 is greater than the curvature of the second arcuate surface 422. The bending angle of the first arcuate surface 421 forms a push-in angle of the part to be supported 2, which facilitates the part to be supported 2 to smoothly enter the corresponding slot 41. A cut-in angle is formed between the second arcuate surface 422 and the inner side wall of the corresponding slot 41, which facilitates the part to be supported 2 to detach from the slot 41. The above-mentioned push-in angle and cut-in angle are obtained through experimental simulation, with high precision and good reliability. In this structure, the first arcuate surface 421 with a larger curvature can effectively improve the stopping effect with the stop frame 5, and can avoid the separation of the stop block 42 from the stop frame 5; and it is convenient to introduce the part to be supported 2 into the slot 41. The second arc surface 422 with a smaller curvature can help guide the stop frame 5 to disengage from the slot 41, thereby achieving the disengagement between the stop frame 5 and the stop block 42. In other embodiments, the curvature relationship between the first arc surface 421 and the second arc surface 422 can be adjusted according to actual needs, which is not limited here.

[0053] In one embodiment, see Figure 1 As a specific embodiment of the anti-falling device provided by the present application, the anti-falling device also includes a first limit rod 7 for limiting the rotation angle of the stop frame 5. The first limit rod 7 is installed on the swing frame 3, and the first limit rod 7 and the stop frame 5 are spaced apart. Among them, the first limit rod 7 can be arranged along the axial direction parallel to the rotating disk 4. In this structure, when the rotating disk 4 rotates in the reverse direction, the second arc surface 422 of the stop block 42 can push the stop frame 5 to rotate, and the first limit rod 7 can limit the rotation of the stop frame 5, so as to avoid the phenomenon that the stop frame 5 cannot automatically return to the initial position due to the excessive rotation angle.

[0054] In some embodiments, an arc groove is provided on the swing frame 3, and a limit rod extending into the arc groove is installed on the stop frame 5. The length of the arc groove can be set according to the angle at which the stop frame 5 needs to swing. When the stop block 42 pushes the stop frame 5 to rotate, one end of the arc groove can resist the limit rod; when the stop frame 5 rotates in the opposite direction under the action of its own gravity, the other end of the arc groove can resist the limit rod. Therefore, the rotation angle of the stop frame 5 can be limited by the cooperation between the two ends of the arc groove and the limit rod. In other embodiments, the angle of the swing frame 3 can also be limited by an elastic member, which can be a spring. One end of the elastic member is connected to the swing frame 3, and the other end is connected to the stop frame 5. When the stop frame 5 rotates a certain angle, the elastic member stretches, and when it reaches the maximum extension position, the rotation of the stop frame 5 can be limited. Alternatively, the elastic member is compressed, and when it reaches the maximum compression position, the rotation of the stop frame 5 can be limited. Moreover, the elastic member can reversely pull or push the stop frame 5 to the initial position under the action of the elastic force, so as to achieve the effect of rapid return of the stop frame 5.

[0055] In one embodiment, see Figure 1 and Figure 2 As a specific embodiment of the anti-falling device provided by the present application, one end of the swing frame 3 away from the turntable 4 is hinged to the support frame 1. In this structure, the stop frame 5 is hinged to the swing frame 3, and the swing frame 3 is hinged to the support frame 1. Through the rotation of the stop frame 5 and the swing frame 3, the automatic mounting and unloading operations between the support member 2 and the turntable 4 can be effectively improved, which is beneficial to the blocking and unhooking operations between the stop frame 5 and the corresponding blocking block 42. The anti-falling device has good reliability and no failure points. In other embodiments, the swing frame 3 can also be fixedly connected to the support frame 1, which is not the only limitation here.

[0056] In one embodiment, see Figure 1 As a specific embodiment of the anti-falling device provided by the present application, the anti-falling device further includes an angle limiting component 6 for limiting the rotation angle of the swing frame 3. The angle limiting component 6 is installed on the support frame 1, and the angle limiting component 6 is spaced apart from the swing frame 3. In this structure, the rotation angle of the swing frame 3 can be limited by the angle limiting component 6, thereby preventing the anti-falling device from failing due to excessive rotation angle of the swing frame 3.

[0057] In one embodiment, see Figure 1As a specific embodiment of the anti-fall device provided by the present application, the angle limiting assembly 6 includes a second limiting rod 61 and a third limiting rod 62 installed on the support frame 1 at intervals, and the swing frame 3 is arranged between the second limiting rod 61 and the third limiting rod 62. In this structure, the second limiting rod 61 and the third limiting rod 62 are respectively arranged on both sides of the swing frame 3, and the second limiting rod 61 and the third limiting rod 62 are respectively arranged at intervals from the swing frame 3; the second limiting rod 61 and the third limiting rod 62 can be arranged along the axial direction parallel to the turntable 4. The second limiting rod 61 and the third limiting rod 62 can respectively limit the swing angles of the swing frame 3 in the left and right directions, and the limiting effect is good.

[0058] In some embodiments, an arc groove is provided on the support frame 1, and a limit rod extending into the arc groove may be installed on the swing frame 3. The length of the arc groove can be set according to the angle at which the swing frame 3 needs to swing. The two ends of the arc groove can cooperate with the limit rod to block the swing frame 3, thereby limiting the angle of the swing frame 3. In other embodiments, the angle of the swing frame 3 can also be limited by an elastic member, which can be a spring. One end of the elastic member is connected to the support frame 1, and the other end is connected to the swing frame 3. When the swing frame 3 swings a certain angle, the elastic member stretches, and when it reaches the maximum extension position, the swing of the swing frame 3 can be limited. Alternatively, the elastic member is compressed, and when it reaches the maximum compression position, the swing of the swing frame 3 can be limited. Moreover, the elastic member can reversely pull or push the swing frame 3 to the initial position under the action of the elastic force, so as to play the role of rapid return of the swing frame 3.

[0059] In one embodiment, see Figure 1 and Figure 2 As a specific embodiment of the anti-falling device provided by the present application, the swing frame 3 includes two support plates 31 arranged at intervals, a connecting plate 32 connecting one end of the two support plates 31, and a connecting shaft 33 connecting the other end of the two support plates 31. The two support plates 31 are respectively hinged on the support frame 1; the turntable 4 is sleeved on the connecting shaft 33, the turntable 4 is arranged between the two support plates 31, and the two ends of the stop frame 5 are respectively hinged on the two support plates 31. Specifically, the two support plates 31 are hinged on the support frame 1 through the hinge shaft 34, the two ends of the connecting plate 32 are respectively connected and fixed to one end of the two support plates 31, and the other ends of the two support plates 31 are respectively connected and fixed to the two ends of the connecting shaft 33. With this structure, the turntable 4 can rotate on the connecting shaft 33, and the two support plates 31 can play a role in limiting the turntable 4 to prevent the turntable 4 from detaching. The swing frame 3 can be realized by the hinge shaft 34 to swing around the support frame 1.

[0060] In one embodiment, both ends of the second limiting rod 61 and the third limiting rod 62 extend out of the support frame 1. Both ends of the second limiting rod 61 extending out of the support frame 1 can respectively block one side of the two support plates 31; and both ends of the third limiting rod 62 extending out of the support frame 1 can respectively block the other side of the two support plates 31. The distance between the second limiting rod 61 and the support plate 31 is equal to the distance between the third limiting rod 62 and the support plate 31, so that the maximum angles of the swing frame 3 swinging left and right can be the same.

[0061] In one embodiment, see Figures 1 to 3 As a specific embodiment of the anti-falling device provided by the present application, the stop frame 5 includes a rotating shaft 51 rotatably mounted on the swing frame 3, connecting rods 52 mounted on both ends of the rotating shaft 51, and a positioning guide column 53 connecting the two connecting rods 52; the rotating shaft 51 is arranged along the axial direction parallel to the turntable 4. Specifically, the two ends of the rotating shaft 51 are rotatably mounted on the two support plates 31, and the two ends of the rotating shaft 51 extend out of the two support plates 31 respectively. The ends of the rotating shaft 51 extending out of the corresponding support plates 31 are installed with connecting rods 52, and the positioning guide column 53 connects and fixes one end of the two connecting rods 52 away from the rotating shaft 51. The two ends of the first limiting rod 7 are respectively mounted on the two support plates 31, and the two ends of the first limiting rod 7 extend out of the two support plates 31 respectively. The end of the first limiting rod 7 extending out of the support plates 31 can be used to block the corresponding connecting rod 52, thereby limiting the rotation angle of the stop frame 5. In this structure, the positioning guide column 53 is located on one side of the swing frame 3 and can be blocked by the two support plates 31. When the blocking block 42 pushes the stop frame 5 , the positioning guide column 53 rotates through the connecting rod 52 and the rotating shaft 51 to achieve hooking and unhooking with the corresponding blocking block 42 .

[0062] The present application also provides a parking device, including the above-mentioned anti-falling device. The specific operation of the parking device is described below in conjunction with the accompanying drawings.

[0063] For ease of description, the plurality of stoppers 42 on the turntable 4 are labeled and respectively referred to as stopper a 42, stopper b 42, stopper c 42 and stopper d 42. The direction indicated by the arrow in the figure is the direction in which the support member 2 moves up and down.

[0064] The process of mounting the support member 2 on the turntable 4 is now described, which may specifically include the following steps:

[0065] 1. Please refer to Figure 4 In the initial position, the positioning guide column 53 of the stop frame 5 cooperates with the first arc surface 421 of the stop block 42 No. d to stop, until the support member 2 is located between the stop block 42 No. a and the stop block 42 No. b.

[0066] 2. Please refer to Figure 4 and Figure 5 , when the support member 2 moves up, the upper end of the support member 2 abuts against the first arc surface 421 of the b stop block 42, and pushes the turntable 4 to rotate counterclockwise by a certain angle, so that the first arc surface 421 of the d stop block 42 is separated from the positioning guide column 53. At this time, the swing frame 3 swings clockwise by a certain angle.

[0067] 3. Please refer to Figure 5 and Figure 6 , the support member 2 continues to move upward, and under the guidance of the first arc surface 421 of the b stopper 42, the support member 2 extends into the slot 41 between the a stopper 42 and the b stopper 42. In the process of the support member 2 moving upward, the turntable 4 rotates counterclockwise, and the c stopper 42 rotates to a position aligned with the positioning guide post 53.

[0068] 4. Please refer to Figure 6 and Figure 7 , wait for the support member 2 to continue to move up, driving the turntable 4 to continue to rotate counterclockwise, at this time, the positioning guide column 53 is separated from the stop block 42 No. C, and rotates counterclockwise to the original position, so that the positioning guide column 53 is located between the stop column No. C and the stop column No. B, and the positioning guide column 53 is in contact with the second arc surface 422 of the stop block No. B; wait for the top end of the support member 2 to abut against the first arc surface 421 of the stop block No. B.

[0069] 5. Please refer to Figure 7 and Figure 8 , the support member 2 is lowered, and under the guidance of the first arc surface 421 of the b stopper 42, the top end of the support member 2 extends into the bottom of the slot 41 between the a stopper 42 and the b stopper 42. At this time, the opening of the slot 41 is tilted upward along the horizontal plane, and the support member 2 will not fall off from the slot 41. During the lowering process, the support member 2 drives the turntable 4 to rotate clockwise, so that the first arc surface 421 of the c stopper 42 abuts against the positioning guide column 53, and the turntable 4 is stopped, thereby locking the support member 2 and completing the connection operation of the support member 2 mounted on the turntable 4.

[0070] The process of separating the support member 2 from the rotating disk 4 is now described, which may specifically include the following steps:

[0071] 1. Please refer to Figure 8 and Fig. 9 , the supporting member 2 moves up to the top of the supporting member 2 and abuts against the first arc surface 421 of the b-block 42; during this process, the supporting member 2 drives the turntable 4 to rotate counterclockwise, and the positioning guide column 53 disengages from the first arc surface 421 of the c-block 42.

[0072] 2. Please refer to Fig. 9 and Fig.10, the support member 2 continues to move upward, so that the top of the support member 2 is separated from the b-block 42. In this process, the turntable 4 rotates counterclockwise, and the second arc surface 422 of the b-block 42 pushes the positioning guide column 53 to rotate clockwise.

[0073] 3. Please refer to Fig.10 and Fig.11 , wait for the support member 2 to move down, wait for the support member 2 to be completely disengaged from the slot 41, wait for the top end of the support member 2 to abut against the second arc surface 422 of the stop block 42 No. a, the second arc surface 422 of the stop block 42 No. b supports the positioning guide column 53 and pushes the positioning guide column 53 to rotate clockwise.

[0074] 4.
