Most current conventional clasping vehicle carriers do not utilize the "dead-spot" feature. Such as: the scheme of adopting 135-degree inclined guide rails (CN107044215A), the scheme of adopting 90-degree round-corner straight-groove guide rails (CN105971338B, CN207739707U and the like) and the scheme of adopting other curved guide rails (CN 206346543U). The wheel lifting device adopts a roller chute structure, the circumferential stress of the rotating arm is mainly borne by the roller, and the safety is not high when the wheel is lifted.
There are also a few carriers that use "dead-spot" characteristics, such as: the combined scheme of the gear rack and the multi-rod mechanism (such as CN20190917) is adopted, and after the gear is separated from the rack, the dead point position of the rod piece has larger instability. When the carrier is vibrated or subjected to other external excitation, the balance relationship is possibly broken, and a serious accident is caused. In addition, the combined scheme of the checking device and the multi-rod mechanism (such as CN110130708A) is adopted, when the rotating arm of the combined scheme is completely unfolded to lift the wheel, the stress of the oscillating rod in the checking mechanism is large, and the structure of the combined scheme is relatively complex.

Detailed Description
The present invention will be described in further detail with reference to the attached drawings, but the present invention is not limited thereto.
As shown in fig. 1 and 2, the carrier of the present invention comprises two carrier units symmetrical to each other, which are connected to each other by an adjusting telescopic part 30, and each of the carrier units comprises a frame, a boom holding part 10 and a traveling part 20 mounted on the frame. The boom clasping portion 10 includes a power transmission mechanism, a chute roller mechanism, a multi-bar mechanism, and a spring gimbal ball assembly. The walking part 20 comprises a driving wheel 201 and a driven wheel 207 which are arranged on the frame, a walking motor 204 for driving the driving wheel 201 to rotate, a belt wheel 203 arranged on the walking motor 204, and a transmission belt 202 for connecting the driving wheel 201 and the belt wheel 203, wherein the driving wheel 201 and the driven wheel 207 are both arranged on the frame 120 through a wheel seat 206, and the walking motor 204 is arranged on the frame 120 through a motor seat 205.
As shown in fig. 3 to 5, the power transmission mechanism includes a carrying section power source 101, a coupling 102, a lead screw 103, a lead screw bearing block 104, a guide rail 105, and a bevel slide plate 106; the series mechanism of the chute roller mechanism and the multi-rod mechanism comprises a chute 107, a shifting rod 108, an input rocker 109, a shortest rod 110, a rotating arm 111, a multi-rod mechanism seat 113, an upper transverse plate 114, a key 115 and a roller 116; the spring universal ball assembly comprises an adjusting screw 117, a spring 118, a universal ball 121, a lower transverse plate 112 where the universal ball is located and a conical hole groove 119 in the rack 120, the lower transverse plate 112 and the multi-rod mechanism seat 113 are fixed with each other, and the pretightening force of the universal ball 121 is changed by rotating the adjusting screw 117.
Wherein, the motion of power transmission mechanism is as follows: the power source 101 of the conveying part provides power, and two lead screws 103 with opposite rotation directions are connected through a coupler 102 to drive a bevel sliding plate 106 on a guide rail 105 to move relative to a frame 120. It is possible to move the two ramp slides 106 on the same transport unit towards or away from each other.
Wherein, the motion of spout roller mechanism is as follows: each inclined slide plate 106 is fixed with a sliding groove 107 on both sides, one end of the shift lever 108 is hinged on the multi-rod mechanism seat 113, the other end is hinged with a roller 116, and the roller 116 can roll in the sliding groove 107, as shown in fig. 7. Therefore, the movement of the slide 106 can rotate the lever 108.
Wherein, the motion of multi-rod mechanism is as follows: the input rocker 109 is connected to the shift lever 108 via a key 115 so that they can rotate simultaneously. The input rocker 109, the shortest rod 110 and the rotating arm 111 are all in hinged contact, and the other side of the rotating arm 111 is also hinged with the multi-rod mechanism seat 113. The multi-lever mechanism achieves the rotation of the rotating arm 111 from the initial position to the fully unfolded position through the rotation of the input rocker 109, as shown in fig. 6, when the rotating arm 111 is fully unfolded, the input rocker 109 and the shortest rod 110 are collinear to form a dead-center jacking effect, and the reverse stroke rotation of the rotating arm 111 when being loaded is prevented.
The adjusting telescopic part 30 between the two carrying units is composed of 4 connecting rods 301. The 4 connecting rods 301 are hinged to form a quadrangle, and then two mutually symmetrical angular vertexes of the quadrangle are hinged to the racks of the two carrying units respectively. As shown in fig. 9 and 10, the distance between the two conveying units can be changed, and the vehicles with different wheel axle distances between the front and rear wheels can be conveyed.
In summary, when the carrier is operated, the swivel arm 111 is first folded to reduce the lateral dimension of the carrier, and then enters under the chassis of the vehicle from the front or rear side of the vehicle through the traveling part 20, and then the power transmission mechanism of the conveying part moves the ramp slide 106. The spring gimbal ball mechanism is now in the locked state shown in fig. 4, locking the multi-bar mechanism mount 113 where the swivel arm is located. Thus, movement of the ramp slide 106, through the chute roller mechanism and the multi-bar mechanism, causes the swivel arms 111 to fully deploy. When the rotating arm 111 is completely unfolded, the hinged part of the poking rod 108 and the input rocker 109 is attached to the inclined plane sliding plate 106, namely, the side surface of the poking rod 108 is completely attached to the inclined plane of the inclined plane sliding plate 106, at the moment, the rotating motion of the chute roller mechanism and the multi-rod mechanism is also completely locked, and reaches the position of a dead point, so that the spring 118 of the spring universal ball mechanism is compressed, and the universal ball 121 leaves the position of the conical hole groove 119. Then, the inclined slide plate 106 drives the multi-rod mechanism with the rotating arm 111 unfolded to integrally and synchronously move in a state of keeping a dead point, so that the automobile wheels are lifted. For vehicles with different wheelbases, the distance between two conveying units can be adaptively changed during the process of lifting the vehicle because the rocker arm 111 on one side of the carrier touches the wheel and is subjected to resistance to close the rocker arm on the other side (at the moment, the wheels of the walking part 20 are in a free rolling state). After the lifting is completed, the carrier carries the vehicle to move to a designated position, and then the vehicle is put down through the furling of the rotating arm 111, and the process is similar to the process of turning away and is not described repeatedly.
