Technical Field

The invention relates to the field of automobile transportation, in particular to a van vehicle.

Background

Many domestic logistics companies or electronic merchants use closed-top van semi-trailers as transportation means, and logistics companies for transporting grain crops generally use vehicles with openable tops to transport grain. The top-sealing van is good in waterproofness, but many loading conditions are lost because the top cannot be opened, and the top-sealing van needs good external sealing conditions, so that the sealing is not easy to process. Therefore, the roof system tarpaulin structure is available in the market at present, and the tarpaulin structure can slide back and forth to realize good sealing and roof opening double effects. However, the roof of the vehicle type capable of sliding back and forth has hidden danger in the aspect of fixation, the sliding roof plays a locking function according to the self gas spring of the sliding roof, but when the vehicle runs on bad road conditions or passes through a deceleration strip, the front and rear cross beams easily overcome the force of the gas spring to jump up automatically to form an opening.

At present, many manufacturers lock the inside of the vehicle by adding a lock, and the vehicle cannot operate from the inside of the carriage to realize the locking function after being loaded with full goods (such as grains). Therefore, how to realize external locking is an important requirement of the vehicle model, and the operation is easy, free, convenient and reliable. As shown in fig. 1 and 2, the van-type semitrailer is a van-type semitrailer for bulk grain, which is commonly used at present, and is provided with a front-back bidirectional sliding tarpaulin top structure. The sliding roof grain van type semi-trailer in fig. 1 is divided into a frame 2', a compartment 3', a front compartment 31', a roof rail 4', a roof tarpaulin system 5', a roof movable cross-beam system 6', and the like. In fig. 2, the movable roof beam system 6 'is mainly divided into a movable beam 61', a gas spring 62', a fixed drag hook 7', and the like, wherein the gas spring 62 'has two positions, namely a beam lifting position and a beam falling position, and is also a position for closing and opening the tarpaulin beam system, the tarpaulin system can slide after opening, a roof of a carriage is opened, cargoes such as grains or suspended cargoes can be loaded from the upper part of the carriage, the beam contacts with a carriage in front of the carriage after being closed, the gas spring 62' is designed to have a certain elasticity in an inclined downward direction, the beam has a downward force, and the carriage top is closed. However, the beam locked by the gas spring is easy to jump up when the road condition is bad or the speed-reducing belt is crossed, and can open the roof to leak rain in rainy days; there are also manufacturers who add the inner pin lock 8 'on the beam base and the gas spring, lock the gas spring to make the gas spring not bounce, thus realize that the beam does not jump open, but the lock is installed in the carriage, namely need to operate in the carriage, so that it can't be realized for loading grain goods such as grains.

In order to improve the above situation and meet various needs of cargo loading, it is highly desirable to develop a van vehicle with an externally mounted rotary lock for locking the cross member of a sliding roof.

Detailed Description

Exemplary embodiments that embody features and advantages of the present invention will be described in detail in the following description. It will be understood that the invention is capable of various modifications in various embodiments, all without departing from the scope of the invention, and that the description and illustrations herein are intended to be by way of illustration only and not to be construed as limiting the invention.

The invention will now be described in further detail with reference to the drawings and examples.

As shown in fig. 3 to 10, the van-type vehicle of the present embodiment mainly refers to a van-type semitrailer, and is particularly suitable for transporting grains. The van vehicle comprises: the traction mechanism, the running gear, the frame that is located running gear top, and the carriage 3 that sets up on the frame.

The carriage 3 has a top opening, and a sliding roof structure 4 is disposed at the top opening of the carriage 3, and the sliding roof structure 4 is used for closing the top opening of the carriage 3.

The cabin 3 includes two cabin 3 end faces along the length direction thereof, and left and right side faces of the vehicle body, the cabin 3 end face in front of the vehicle body is a front cabin 31, the cabin 3 end face in rear of the vehicle body is a rear cabin (not shown in the drawings), and the specific structure is illustrated by taking the front cabin 31 as an example in this embodiment. Further, the tops of both side surfaces of the carriage 3 (i.e., the top side beams) are respectively provided with a slide rail 32, and the slide rails 32 are arranged along the length direction of the carriage 3.

The sliding roof structure 4 includes: a ceiling 41 and a sliding beam 42. The ceiling 41 is provided to cover the top opening of the vehicle compartment 3. Further, the slide cross member 42 includes: beam body 421, movable connector 422 and gas spring 423.

The beam body 421 and the movable connecting piece 422 are arranged in parallel along the top of the carriage 3, and are movably connected with each other. The ceiling 41, the beam body 421 and the movable connecting piece 422 are sequentially connected along the length direction of the carriage 3, wherein the beam body 421 and the movable connecting piece 422 are matched with the sliding rail 32 at the top of the top side beam of the carriage 3, so that the beam body 421 and the movable connecting piece 422 can slide back and forth along the length direction of the carriage 3 together.

In actual use, the ceiling 41 may also be connected above the movable connector 422, that is, the ceiling 41 covers the beam body 421 and the movable connector 422.

The gas spring 423 is disposed below the movable connecting member 422 and is used for being matched with the movable connecting member 422. Under the action of external force, one side of the movable connecting piece 422 far away from the beam body 421 can be lifted up or fall down in an upward tilting way to be buckled with the top of the carriage 3, so that the sliding beam 42 is opened and closed; wherein, the movable connector 422 is reset to the transverse state in a state of being buckled with the top of the carriage 3. When the sliding cross beam 42 moves to the position of the front car 31, the movable connecting piece 422 falls down to be buckled with the top of the car 3, so that the opening of the car 3 at the position can be closed.

In practical use, the sliding cross beam 42 may also be an integral structure, which is disposed transversely along the cabin 3 and can slide back and forth along the length direction of the cabin 3, so as to drive the ceiling 41 to close and open the top of the cabin 3.

The van vehicle of the present embodiment further includes a rotary external lock for locking the sliding roof structure 4 to the cabin 3 after the sliding roof structure 4 closes the top opening at the front cabin 31 of the vehicle.

This rotatory external lock includes: the lock body 5, the fixed pin 6 and the supporting seat 7 which are matched with each other.

The fixed pin 6 is arranged on the sliding roof structure 4, and the fixed pin 6 can extend out of the end face of the carriage 3 in the length direction after the sliding roof structure 4 seals the carriage 3. In the present embodiment, the fixing pin 6 is specifically disposed on the movable connecting member 422. The fixing pin 6 replaces the fixing hook in the prior art.

In other embodiments, when the sliding beam 42 is an integral component, the fixing pin 6 is disposed on the sliding beam 42, and similarly, the fixing pin 6 extends beyond the end surface of the car 3 in the length direction after the sliding roof structure 4 closes the top of the car 3, which is not limited herein.

The supporting seat 7 is provided on the outer side surface of the front car 31, and the lock body 5 is connected with the front car 31 through the supporting seat 7 so that the lock body 5 is better matched with the fixing pin 6.

In other embodiments, the support base 7 may be omitted so that the lock body 5 and the fixing pin 6 can cooperate.

The lock body 5 includes: a pin 51, a lock 52 and a spring 53. The pin 51 is vertically disposed on the outer side surface of the support seat 7. One end of the lock catch 52 is hinged to the pin 51, and the other end of the lock catch 52 is provided with a hook-shaped structure 521, and the lock catch 52 can rotate in a vertical plane around the axis of the pin 51, so that the hook-shaped structure 521 can lock the fixed pin 6 or unlock the lock catch with the fixed pin 6.

One end of the spring 53 is fixed to the outer side surface (i.e., the surface far from the cabin 3) of the support seat 7 at a position close to the pin 51 by the fastener 55, and the other end is fixed to the outer side surface of the lock catch 52 at a position close to the hook-like structure 521 by the fastener 55.

Further, the lock body 5 further includes: two limiting pins 54 disposed on the outer side surface of the support seat 7, wherein the two limiting pins 54 are used for stopping the lock catch 52 and limiting the rotation angle range of the lock catch 52. The two limiting pins 54 are distributed in the up-down direction of the pin shaft 51 (i.e. the up-down direction of the height of the carriage 3), and the extending length of the two limiting pins 54 on the outer side surface of the supporting seat 7 is smaller than the distance between the spring 53 and the outer side surface of the supporting seat 7, so that interference of the limiting pins 54 when the lock catch 52 rotates is avoided.

Referring to fig. 6, the positions of the two stopper pins 54 are shown, which are determined according to the movement locus R1 of the locker 52 and the movement locus R2 of the spring 53. Specifically, in the process of rotating the lock catch 52 from the position of any one of the stopper pins 54 to the position of the other stopper pin 54, the length of the spring 53 stretched is gradually increased and then gradually decreased. That is, the spring 53 undergoes a "re-tension" process that is slightly tensioned at both of the stopper pins 54 and has a heavy tension during rotation of one stopper pin 54 position to the other stopper pin 54 position, so that the catches 52 are not excessively moved from each other at both stopper pin 54 positions without the action of external force, i.e., the catches 52 are stable at both stopper pin 54 positions.

Preferably, the latch 52 is further provided with an outer hook 522, and the outer hook 522 is disposed opposite to the hook-shaped structure 521. Referring to fig. 8 and 10, in actual operation, the rotary external lock is installed at the top of the cabin 3, which is three meters high from the ground, and an operator can operate the rotary external lock through a long rod. When the outer hook 522 is hooked by the long rod and pulled down, the hook structure 521 of the latch 52 releases the fixing pin 6 (rotated counterclockwise in the drawing) disposed on the sliding beam 42, and the sliding beam 42 is opened (i.e., the sliding roof structure 4 is opened); when the pull rod pushes the outer hook 522, the hook structure 521 of the latch 52 rotates upward (clockwise in the drawing) to catch the fixing pin 6, and the opening of the slide cross member 42 is restricted, thereby preventing the automatic jump-up of the slide cross member 42 (i.e., locking the slide top structure 4).

In the present embodiment, the number of the sliding cross members 42 in the sliding roof structure 4 is two, which slide toward both end portions of the vehicle cabin 3, respectively, to achieve closing or opening of the top portion of the vehicle cabin 3.

The working principle of the rotary external lock of the embodiment is as follows: the sliding roof structure 4 slides to the front compartment 31 position and closes the opening position. The lock body 5 is rotated upwards so that the hook-shaped structure 521 on the lock catch 52 hooks the fixing pin 6, and the lock catch 52 can be fixed at this position under the action of the spring 53. When the rotary external lock needs to be opened, the lock body 5 is reversely rotated, so that the hook-shaped structure 521 on the lock catch 52 is not hooked on the fixed pin 6, namely, the locking of the sliding roof structure 4 is released.

According to the van vehicle, the rotary external lock is arranged outside the top of the carriage, so that the sliding roof structure is further locked, the operation is convenient, and the boxing efficiency is improved. Meanwhile, the use requirement of the market on the sliding roof van is met, the practicability of the sliding roof structure on the van is effectively increased, and the waterproofness and the safety of the van are provided.
