Referring to fig. 1 and 3, as mentioned in the background of the invention, the body of the piggyback car may generally include a body portion 1 and a separable tray portion 4, and the structure of the body portion 1 and the tray portion 4 may refer to the prior art, which is not limited herein; the separation mode of the supporting part 4 from the main body part 1 mainly comprises translational separation and rotational separation, correspondingly, the mode of remounting the supporting part 4 on the main body part 1 can also comprise rotational reset and translational reset, and no matter what reset mode is adopted, a transverse stopping mechanism 6' is required to be arranged to determine the reset position of the supporting part 4, so that the supporting part 4 can be ensured to be accurately installed on the main body part 1.

To this end, the present invention provides a lateral stop mechanism 6' for a tray, which, together with fig. 2 and fig. 4-6, comprises: a stop beam 61 ' hinged to the body 1, the two ends of the stop beam 61 ' being a driving end 611 ' and a stopping end 612 ', respectively, a hinge axis 613 ' of the stop beam 61 ' being located between the driving end 611 ' and the stopping end 612 ', and the hinge axis 613 ' being fixedly arranged, in particular being fixable, to the body; a fixedly arranged limit beam 62', which can also be fixed to the body part 1; in the stopping state, the limiting beam 62 ' is abutted against the outer side of the stopping beam 61 ' along the transverse direction, and the stopping beam 61 ' can form a transverse stopping for the support part 4; in the disengaged state, the driving end 611 'is forced to rotate to drive the stopping end 612' to release the stop of the holder 4.

By adopting the structure, in the stopping state, the limit beam 62 'can be abutted against the stop beam 61' along the transverse direction so as to provide the transverse supporting force for the stop beam 61 ', and then the stop beam 61' forms transverse stopping for the support part 4, so that the accurate resetting of the support part 4 can be ensured; in the gear-releasing state, the driving end 611 ' can be stressed to drive the whole stop beam 61 ' to rotate, and further the stopping end 612 ' can be driven to rotate to release the stop, so as not to affect the normal separation of the holder 4 and the body 1.

More importantly, in the stopping state, when the supporting part 4 resets and hits the stopping beam 61 ', only the stopping end part 612' and the limiting beam 62 'are stressed, and the driving end part 611' which is the moving part of the transverse stopping mechanism is not stressed, which has a key effect on ensuring the reliability of the transverse stopping mechanism provided by the invention.

It should be noted that the embodiment of the present invention does not limit the source of the driving force received by the driving end 611 'during the gear shifting, and a manual driving scheme may be adopted, for example, a gear shifting component such as a gear shifting lever may be provided, and when the gear shifting is required, the gear shifting component may be manually operated by a worker to generate the driving force for the driving end 611'; or, an automatic driving scheme may also be adopted, in this case, the power source may be a motor, an air cylinder, an oil cylinder, or the like, the power source may be mounted on the vehicle body, or may be mounted on the ground equipment, which may be specifically selected according to actual conditions, and a transmission mechanism may also be disposed between the power source and the driving end portion 611' to transmit the driving force of the power source.

Further, the lock device may further include a first limiting member 63 ', and the first limiting member 63 ' may be specifically installed on the main body 1, and in the unlocking state, the stop beam 61 ' may abut against the first limiting member 63 ', so as to avoid an excessive rotation of the stop beam 61 '.

Here, the shape of the first limiting member 63' is not limited in the embodiment of the present invention, and may be a plate shape, a block shape, a column shape, or the like, and may be specifically determined according to actual situations; similarly, the embodiment of the present invention does not limit the number and the installation positions of the first stoppers 63', as long as the above-described effects can be achieved. In an exemplary aspect of the invention, the first limiting member 63 'may be formed by extending a cover plate of the main body 1, so that the first limiting member 63' is not required to be specially provided, and the number of parts may be reduced.

In the disengaged state, i.e. when the stop beam 61 ' abuts against the first stop member 63 ', the center of gravity of the stop beam 61 ' may be longitudinally offset from the hinge axis 613 ' and located on the side of the stop end 612 '. Thus, when the driving force acting on the driving end 611 ' is removed, the stopper beam 61 ' can be automatically rotated to the stopper state by the gravity of the stopper beam 61 ' itself without providing another driving part, and the structure of the apparatus can be simplified.

And/or, an elastic member 65 'may be further included, and the elastic member 65' may act on the stopper beam 61 ', and the amount of deformation of the elastic member 65' may be increased during the unlocking process to gather the elastic force. Thus, when the driving force acting on the driving end 611 ' is removed, the elastic force accumulated by the elastic member 65 ' can be released to cooperatively drive the stopper beam 61 ' to rotate back to the stopping state by itself or in cooperation with the aforementioned gravity.

The elastic member 65 'may be a torsion spring, which is externally sleeved on the hinge shaft 613', and has two extending ends, one of which may be fixed (or may be abutted against a fixed member, such as the body portion 1), and the other of which may be abutted against the stopper beam 61 ', so that when the stopper beam 61' rotates to release the stopper state, the torsion spring may gather a torsional deformation force, and when the driving force applied to the driving end 611 'is removed, the torsional deformation force may be released to drive the stopper beam 61' to automatically rotate.

The elastic member 65 ' may be a linear spring, such as a tension spring, a compression spring, or a spring element that generates an elastic force by an axial displacement, and the linear spring may be a tension spring, in which one end of the tension spring may be fixed and the other end may be connected to the stopper beam 61 ', for example, in the case of the scheme in fig. 4, so that the elastic force may be accumulated when the stopper beam 61 ' rotates to release the stopper.

The elastic member 65' may be an elastic member in the form of an elastic block, an elastic ball, a tensile cord, or the like, in addition to the torsion spring and the linear spring, as long as the above technical effects can be achieved.

Furthermore, a second limiting member 64 'may be further included, and in the stopping state, the stopping beam 61' may abut against the second limiting member 64 'to limit the position of the stopping beam 61' in the stopping state. The second limiting members 64 'may be similar in structure, number and installation position to the first limiting members 63', and will not be described repeatedly.

Moreover, by the support of the second limiting member 64 ', the stop beam 61 ' and the limit beam 62 ' can be arranged with a gap in the vertical direction, so that the limit beam 62 ' does not need to bear the gravity of the stop beam 61 ', accordingly, the connection part of the limit beam 62 ' and the body part 1 does not generate shear stress, and the connection reliability of the limit beam 62 ' and the body part 1 can be high.

With respect to the lateral stopper mechanism 6 'of the bracket 4 according to each of the above embodiments, the structure of the stopper beam 61' will be described in the following embodiments of the present invention.

In the stopping state, referring to fig. 2, the driving end 611 ' may be an end gradually inclined from top to bottom toward the stopping end 612 ', so that when the driving end 611 ' receives an upward driving force, the stopping beam 61 ' will naturally rotate toward the direction of releasing the stopping state, so as to ensure that the stopping beam 61 ' can be smoothly unlocked.

It is understood that adjusting the shape of the driving end 611 ' actually adjusts the driving force and the acting direction of the driving end 611 ', so that the rotational unlocking of the stopper beam 61 ' can be realized by adjusting the direction of the driving force in specific implementation.

In the stopping state, a bent corner bent downward may be provided at an end of the stopper beam 61 'away from the driving end 611', and the bent corner may serve as the stopper end 612 ', and the bent corner may be provided to increase the strength of the stopper end 612' and to avoid the vehicle body and the brake pipe guard (not shown).

Referring to fig. 6 again, the hinge axis 613 ' of the stop beam 61 ' may be a stepped axis, and specifically may include a large diameter section 613a ' and a small diameter section 613b ', wherein the large diameter section 613a ' may be used to connect with the body portion 1, and the stop beam 61 ' may be mounted on the large diameter section 613a '; a third limiting member 613c 'may be further included, and the third limiting member 613 c' may be specifically a nut, which may be mounted to the small diameter section 613b 'to cooperate with the body portion 1 to define the mounting position of the stop beam 61'. It should be understood that the third limiting element 613c 'mainly serves to limit the rotation of the stop beam 61' and is not locked, so as to ensure smooth rotation after the installation.

A gasket 613d 'may be further disposed between the third limiting member 613 c' and the stop beam 61 ', and the gasket 613 d' may be made of rubber, metal, or the like, so as to avoid direct friction between the stop beam 61 'and the third limiting member 613 c', and have a positive effect on reducing wear.

The invention also provides a piggyback car, which comprises a car body, wherein the car body comprises a body part 1 and a support part 4, the support part 4 and the body part 1 can be separated, and the structures of the body part 1 and the support part 4 can refer to the prior art, which is not limited herein; unlike the prior art, the piggyback car may further include the lateral stopper mechanism 6' of the tray 4 according to each of the above embodiments.

Since the above-mentioned transverse stopping mechanism 6 'has the technical effects, the piggyback car having the transverse stopping mechanism 6' also has similar technical effects, and therefore, the detailed description thereof is omitted.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that it is obvious to those skilled in the art that various modifications and improvements can be made without departing from the principle of the present invention, and these modifications and improvements should also be considered as the protection scope of the present invention.
