The terminology used in the description is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

In various embodiments, for convenience in description and not limitation of the disclosure, the term "coupled" as used in the description and claims of the present application is not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships are changed accordingly.

Fig. 1 is a schematic view of the structure of the carrier. As shown in fig. 1, the carrier is for moving a vehicle and includes a front section assembly 10, a rear section assembly 20, and an extreme position detecting device 30. The front assembly 10 can be used to hold and load the front wheel of a vehicle and the rear assembly 20 can be used to hold and load the rear wheel of a vehicle, by the cooperation of the front assembly 10 and the rear assembly 20, the function of moving the vehicle is achieved. Because the carrier needs move to the below rear load vehicle of vehicle, because the space below the vehicle is limited, require that the volume of carrier self is littleer, and whole thickness is littleer, and is extremely limited to the installation space of its inner structure, also higher to the requirement of installation.

In some embodiments, the front assembly 10 and the rear assembly 20 may be connected by a cable, so as to communicate and supply power between the front assembly 10 and the rear assembly 20. In other embodiments, the front assembly 10 and the rear assembly 20 may be independently powered and signal transmission between the two may be realized by optical signals or electromagnetic signals. However, since the front assembly 10 and the rear assembly 20 are required to cooperate with a loaded vehicle, it is required that the relative positions of the front assembly 10 and the rear assembly 20 do not exceed a preset limit position, that is, the distance between the front assembly 10 and the rear assembly 20 does not exceed a limit distance at which both are in the limit position. The extreme position detecting device 30 is used for detecting whether the distance between the front assembly 10 and the rear assembly 20 exceeds the extreme distance, and sending out corresponding detection signals when the front assembly 10 and the rear assembly 20 are in the extreme positions.

Fig. 2 is a schematic configuration diagram of the extreme position detecting device 30. As shown in fig. 2, the extreme position detecting means 30 includes a detection switch 33, a connection cord 31, and a trigger mechanism. The detection switch 33 is disposed on the front-stage component 10 or the rear-stage component 20, and may be a mechanical touch switch or a photoelectric switch, and when the front-stage component 10 and the rear-stage component 20 are located at the limit positions, the trigger mechanism touches the detection switch 33 to send a detection signal, so as to achieve an effect of actively detecting the limit positions.

The connecting string 31 may be a flexible connecting body such as a cable or a flexible chain, which connects the front assembly 10 and the rear assembly 20, and for example, one end of the connecting string may be connected to the front assembly 10, and the other end of the connecting string may be connected to the rear assembly 20. The detection switch 33 and the trigger mechanism are connected to the front-stage assembly 10 or the rear-stage assembly 20. When the front assembly 10 and the rear assembly 20 are in the extreme positions, the connecting rope 31 is pulled by the front assembly 10 and the rear assembly 20 to pull the trigger mechanism, which triggers the detection switch 33 to send out a detection credit. In addition, the connecting rope 31 is also connected between the front assembly 10 and the rear assembly 20, when the distance between the front assembly 10 and the rear assembly 20 exceeds the limit distance, the connecting rope 31 is straightened to play a role of mechanical limitation, and the front assembly 10 and the rear assembly 20 are prevented from continuously exceeding the limit position. For convenience of installation, the extreme position detecting device 30 may further include a second fixing block 37, the second fixing block 37 being installed at the front assembly 10 or the rear assembly 20, and an end of the connection rope 31 being connected to the second fixing block 37.

Fig. 3 is a schematic structural view of the trigger mechanism. As shown in fig. 3, the trigger mechanism includes a trigger 34, an elastic member 35, an adjusting member 36, a first guide 344, and a second guide 311. For convenience of installation, the adjusting element 36 and the triggering element 34 may be mounted on the first fixing block 32, and the first fixing block 32 is connected to the front assembly 10 or the rear assembly 20 to mount and connect the triggering mechanism. Illustratively, the first fixing block 32 may be connected to the rear assembly 20 by means of screws and inserts, the second fixing block 37 is connected to the front assembly 10, and one end of the connecting rope 31 is connected to the first fixing block 32 and the other end is connected to the second fixing block 37.

The trigger 34 has a T-shaped structure, and includes a trigger portion 341 and a protrusion portion 342, the trigger portion 341 has a substantially linear structure, one end of the trigger portion is rotatably connected to the first fixed block 32 at a hinge point 343, and the other end of the trigger portion is suspended and extends toward the detection switch 33. The protrusion portion 342 is connected to a middle position of the trigger portion 341 and extends in a width direction of the trigger portion 341. The adjusting member 36 is movably connected to the first fixing block 32 and to the elastic member 35 for adjusting the position and tension of the elastic member 35. Specifically, the adjusting member 36 includes a screw, the first fixing block 32 is provided with a threaded hole, the screw is screwed into the threaded hole to be in threaded connection with the second fixing block 37, and the end of the screw is connected to the end of the elastic member 35, so that the end position and the tension of the elastic member 35 can be adjusted by screwing in or unscrewing the screw. It will be appreciated by those skilled in the art that the trigger 34 may be other types of structures, such as a disc-shaped structure, and the detection switch 33 is triggered by the connection rope 31 pulling the turntable to rotate.

The elastic member 35 is used for resetting the trigger 34 when the connecting rope 31 is released. As an example, the elastic member 35 may be a spring having one end connected to the triggering member 34 and the other end connected to the adjusting member 36. When the connection cord 31 pulls the protrusion 342 of the triggering member 34, the triggering portion 341 rotates and stretches the elastic member 35, so that the elastic member 35 is deformed. After the connecting rope 31 is released, i.e. the distance between the front assembly 10 and the rear assembly 20 is smaller than the limit position, the elastic member 35 may pull the trigger member 34 to rotate to the initial position and disengage from the detection switch 33, so that the detection switch 33 may be reset.

With continued reference to fig. 2 and 3, in order to adjust the orientation of the connecting rope 31, in some embodiments, the extreme position detecting device 30 may further include a first guiding element 344 and a second guiding element 311, and the first guiding element 344 and the second guiding element 311 may be rod-shaped structures, wherein the first guiding element 344 is connected to the protruding portion 342 of the triggering element 34, the second guiding element 311 is connected to the rear assembly 20 of the carrier at a position close to the triggering element 34, one end of the connecting rope 31 is connected to the second fixing block 37, and then extends toward the rear assembly 20, and is connected to the first fixing block 32 by bypassing the first guiding element 344 and the second guiding element 311 in sequence. When the relative position between the front assembly 10 and the rear assembly 20 of the carrier is in the extreme position, the connecting rope 31 is pulled by the front assembly 10 and the rear assembly 20 to pull the trigger 34 to rotate through the first guide 344, so that the end of the trigger 341 touches the detection switch 33 to send out a detection signal.

The operation of the extreme position detecting device 30 will be described in detail below with reference to fig. 2 and 4.

Fig. 2 shows the extreme position detecting device 30 in a normal state. As shown in fig. 2, in a normal state, the front assembly 10 and the rear assembly 20 are located in the limit position, and the distance between the front assembly 10 and the rear assembly 20 is smaller than the limit distance. At this time, the connection cord 31 is in a slack state, and the trigger 34 is pulled by the spring to be disengaged from the detection switch 33.

Fig. 4 is a schematic structural diagram of the trigger mechanism in a trigger state. As shown in fig. 4, when the front assembly 10 and the rear assembly 20 are located at the extreme positions, the connection rope 31 is pulled and stretched by the front assembly 10 and the rear assembly 20, and under the guidance of the first guide 344 and the second guide 311, the connection rope 31 pulls the protrusion 342 of the trigger 34, and the protrusion 342 drives the trigger 341 to rotate around the hinge point 343, so that the end of the trigger 341 touches the detection switch 33 to send out a detection signal. Meanwhile, the rotation of the triggering portion 341 may also stretch the elastic member 35, so that after the connection rope 31 is released, that is, the connection rope 31 is in a relaxed state, the elastic member 35 may pull the triggering member 34 to reset, and simultaneously release the detection switch 33.

When the above-mentioned extreme position detection device 30 applied to the carrier and the relative position of the carrier between the front assembly 10 and the rear assembly 20 of the carrier are in the extreme position, the connecting rope 31 can pull the trigger 34 to move to trigger the detection switch 33, so that the detection signal can be actively triggered, which is beneficial to improving the detection accuracy. Moreover, the limit position detection device 30 occupies a small volume, and can realize a detection function by using a small thickness, thereby improving the application range of the limit position detection device 30. Meanwhile, the position of the elastic part 35 is adjusted by the adjusting part 36, so that the position of the trigger part 34 when the detection switch 33 is triggered can be adjusted, the limit positions of the front assembly 10 and the rear assembly 20 can be adjusted, and the adjustment is more convenient.
