Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle connection structures, and in particular relates to a connection structure for connecting front and rear vehicle bodies and a vehicle with the connection structure. Background Art

[0002] Taking swampy road conditions as an example, traditional single-section tracked vehicles or wheeled vehicles have limited passing performance, and vehicles are easily stuck in swamps and difficult to drive out. Especially when harvesting reeds in swampy environments, the harvesting efficiency is severely limited, and vehicles may even get stuck in the swamp and be unable to get out, let alone harvesting reeds. Therefore, it is very inconvenient for current vehicles to harvest reeds in swampy areas.

[0003] The utility model patents with announcement numbers CN220674425U, CN217160462U and CN216905966U are all single-section vehicles with certain passing and escape capabilities, and have good results in harvesting reeds or weeds. However, when the multi-section vehicle body is towed and articulated, it is difficult to drive in some swampy areas with more muddy roads and more serious water accumulation, and the vehicle will slip, sink or tilt more seriously. Moreover, the towed and articulated multi-section vehicle body is more cumbersome and inflexible, and the driving body bears a greater load, which increases the difficulty of operating in swampy areas.

[0004] At present, there are also towing mechanisms used between multiple vehicle bodies, such as the common trailer hook, but this simple connection structure can only play the role of towing and pulling, and is only suitable for hard roads. When the vehicle is deeply stuck in the wetland in a muddy swamp, the vehicle is heavy and the vehicle posture is changeable, the trailer hook cannot withstand such a load, and deformation and damage frequently occur during the road test, so it is not suitable.

[0005] Therefore, it is particularly important to develop a more effective vehicle body connection structure to improve the vehicle's ability to pass and escape. Utility Model Content

[0006] The utility model aims to solve the technical problems in the prior art that the connection of multiple vehicle bodies is bulky and inflexible, and the vehicle has limited escape and passing capabilities, and to provide a front and rear vehicle body connection structure and a vehicle with the connection structure to improve the current shortcomings.

[0007] In order to achieve the above-mentioned purpose, on the one hand, the utility model provides a front and rear vehicle body connection structure.

[0008] It comprises an outer connecting member and an inner connecting member which are sleeved with each other and are connected to each other in a relatively rotatable manner; the outer connecting member is connected to one vehicle body, and the inner connecting member is movably hinged to another adjacent vehicle body through a hinge mechanism.

[0009] Optionally, the articulated mechanism includes at least one connecting rod, one end of which is hinged to the inner connecting member, and the other end of which is hinged to an adjacent vehicle body.

[0010] Optionally, the connecting rod is provided with at least one driving component with one end hinged thereto, and the driving end of the driving component is hinged to the inner connecting member.

[0011] Optionally, the outer connecting member and the inner connecting member are tubular members, rod-shaped members or spherical members which are sleeved together.

[0012] Optionally, the outer connecting member and the inner connecting member are provided with limiting members for preventing them from being separated from each other.

[0013] Optionally, the outer connecting member or the inner connecting member is provided with a limiting member for preventing separation from each other.

[0014] Optionally, the inner connecting member is provided with a passage passing through both ends thereof.

[0015] Optionally, a bearing is provided between the outer connecting member and the inner connecting member.

[0016] On the other hand, the utility model provides a vehicle, which includes a vehicle provided with the above-mentioned front and rear vehicle body connection structure.

[0017] Optionally, the vehicle is a tracked vehicle or a wheeled vehicle.

[0018] After adopting the above structure, the utility model has the following beneficial effects:

[0019] The front and rear vehicle body connection structure of the utility model can realize the connection of two or even more vehicle bodies. Compared with the traditional towing method, it not only plays a towing effect between adjacent vehicle bodies, but also can realize the individual change of the height, horizontal angle and roll angle between each vehicle body, fully adapting to the road conditions in swampy areas, and each vehicle body has a flexible activity angle.

[0020] In addition, adjacent vehicle bodies can also be connected to drive shafts to achieve transmission effects, especially two-section tracked vehicles can achieve four-wheel drive effects, with better passing performance and escape performance. In addition, there are driving components on the connecting rod, which can use the driving force to achieve a lateral twisting effect between the two vehicle bodies, thereby improving the vehicle's ability to escape from swamps.

[0039] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the following Figures 1 to 12It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. Embodiment 1

[0040] Reference Figures 1 to 12 The utility model provides a front and rear vehicle body connection structure.

[0041] The invention comprises an outer connecting member 101 and an inner connecting member 102 which are sleeved with each other and are connected to each other in a relatively rotatable manner. The outer connecting member 101 and the inner connecting member 102 are both tubular members, rod-shaped members or spherical members which are sleeved with each other.

[0042] like Figure 9-11 As shown, when a tubular member or a rod-shaped member is used, the outer connecting member 101 and / or the inner connecting member 102 is provided with a limiting member 1023 for preventing separation from each other. For example, when the limiting member 1023 is a stepped platform extending toward the periphery, it can ensure that axial separation does not occur between the outer connecting member 101 and the inner connecting member 102, and an axial rotational connection can be achieved between the two.

[0043] like Fig.12 As shown, when a spherical member is used, the outer connecting member 101 and the inner connecting member 102 are difficult to separate in the axial direction, and have a certain axial limiting effect. Moreover, the outer connecting member 101 and the inner connecting member 102 can not only realize the rotation connection in the axial direction, but also realize the rotation of a certain three-dimensional angle, which is more flexible. However, this structure has limitations in processing, installation and later maintenance, and the cost is also high.

[0044] Figure 1-Figure 11 The outer connector 101 and the inner connector 102 shown in the figure are both in a tubular shape, so that the two can realize axial rotation, and this structure is simple and very reliable, especially suitable for swampy areas with harsh environments. In practice, the axial direction of the outer connector 101 and the inner connector 102 is consistent with the direction of travel of the vehicle. This structure is to achieve the change of the roll angle of the vehicle body. In layman's terms, it is to achieve the lateral swing of the vehicle body in the direction of travel. Even if the structure here sinks into the mud, it will not cause blockage or damage, and the use process is very reliable.

[0045] Of course, the outer connector 101 or the inner connector 102 can also be directly replaced by a bearing, or a bearing can be added between the outer connector 101 and the inner connector 102. In other words, as long as the axial rotation connection between the two connectors can be achieved. Although the use of bearings can achieve a better smooth rotation effect, in muddy and complex swamp areas, once mud enters, it is easy to cause the bearing to be blocked, affecting the smooth rotation between the two, and then affecting the roll (i.e. left and right swing) angle of the vehicle body, and the failure rate remains high. Therefore, the more sophisticated the accessories, the easier it is to be damaged in a harsh working environment, and they are not suitable.

[0046] In the above structure, the outer connecting member 101 is connected to a vehicle body 41, and the two are preferably fixedly connected, so that the two can move together; the inner connecting member 102 is movably articulated with the adjacent vehicle body 42 through an articulation mechanism, specifically to achieve articulation in height and horizontal directions, that is, the vehicle's height fluctuation direction and left and right direction steering. The articulation part adopts the common articulation ear 1022 structure, which is simple and reliable.

[0047] This structure can realize the changes of multiple angles between the two sections of the vehicle body. Specifically, the rotation between the two connecting parts can realize the change of the vehicle body roll (i.e. lateral swing) angle, and the articulated mechanism can realize the change of the vehicle body ups and downs elevation angle (i.e. height) angle, as well as the lateral (i.e. left and right) angle. These three angle changes can make the vehicle body achieve a twisting creeping effect in muddy swamps, and the vehicle posture is changeable and the movement is more flexible. Therefore, it has the technical effect of simple and reliable structure and flexible movement.

[0048] As a further explanation, in this embodiment, the hinge mechanism includes at least one connecting rod 201, and in practice, the number of the connecting rods 201 is set to four (eg Figure 1 and Figure 2 As shown in FIG. 1 , one end of the connecting rod 201 is hinged to the inner connecting member 102, which is a hinge point 1 202. The hinge here is preferably hinged in the lateral direction (i.e., it can achieve left-right steering). The other end of the connecting rod 201 is hinged to the adjacent vehicle body 42. The hinge here is preferably hinged in the elevation direction (i.e., it can achieve the height of the vehicle), which is a hinge point 2 203. Figure 4 Compared with the traditional drag-type hook connection structure, this hinge structure can disperse the force, and multiple hinge points are jointly stressed, which reduces the stress on the hinge, is not easy to be damaged, and has a longer service life.

[0049] It should be noted that the arrangement direction of the hinge mechanism can be adjusted according to actual needs. For example, the hinge effect will not be affected if the two ends are arranged in reverse. Embodiment 2

[0050] The technical problem to be solved by this embodiment is to achieve a lateral twisting effect between adjacent vehicle bodies.

[0051] refer to Figure 1-Figure 6 The connecting rod 201 is provided with at least one driving component 300 (such as a hydraulic cylinder) with one end hinged thereto. In practice, two driving components 300 are provided, and the two are arranged symmetrically. The driving end of the driving component 300 is hinged to the inner connecting member 102. By providing the driving component 300, an additional driving force can be applied between adjacent vehicle bodies, thereby achieving relative twisting of adjacent vehicle bodies, and thus greatly improving the ability of the vehicle to escape from trouble.

[0052] For example, when the right driving component 301 is extended (such as Figure 5 As shown in FIG. 1 ), the two adjacent vehicle bodies will rotate (ie twist) relative to each other, which is conducive to the vehicle turning left. When the left driving component 302 is extended, the two adjacent vehicle bodies will rotate (ie twist) relative to each other, which is conducive to the vehicle turning right. If this step is repeated, the vehicle twists more frequently, which improves the adhesion of the vehicle and is more conducive to the vehicle getting out of the swamp.

[0053] Specifically, if the driving component 300 is not provided, the adjacent vehicle bodies will only have a pulling effect. When the driving component 300 is in motion, the driving force can be used to push the vehicle body, and the two vehicle bodies will rotate (ie twist) relative to each other at the hinge point 202. By using this repeated driving force, the vehicle will continuously twist laterally, thereby improving the adhesion of the vehicle and improving the ability of the vehicle to escape from trouble.

[0054] Of course, the above structure also facilitates the turning of the vehicle, reduces the turning radius, and makes the vehicle move more flexibly. Embodiment 3

[0055] This embodiment is to achieve a synchronous driving effect of multiple vehicle bodies.

[0056] As in conventional multi-section vehicles, only the front of the vehicle has the driving force to pull the rear vehicle body. Now, by providing a channel 1021 through both ends of the inner connecting member 102, the placement of the transmission shaft 5 can be achieved (refer to Figure 10-12 Specifically, the transmission shaft can pass through the channel 1021 to provide driving force for the drive wheels on the adjacent vehicle bodies, thereby achieving driving force for the wheels or tracks on the adjacent vehicle bodies, achieving the effect of four-wheel drive, six-wheel drive or even eight-wheel drive. According to actual needs, power sources can also be installed on other vehicle bodies to provide more power, and the transmission effect is provided between the adjacent vehicle bodies through the transmission shaft 5.

[0057] In order to adapt to the change of transmission angle, accessories such as universal joints, couplings, clutches, etc. can also be set on the transmission shaft. Of course, the transmission shaft can also be replaced by an oil circuit to provide power for the hydraulic motor. In addition, the transmission shaft 5 or the pipeline is centrally arranged in the channel 1021, and the wiring harness can also be centralized to prevent tangling and clutter, which is easy to maintain.

[0058] On the other hand, the utility model provides a vehicle, which includes a vehicle provided with the above-mentioned front and rear vehicle body connection structure, through which the two or even multiple vehicle bodies can be flexibly turned and driven together.

[0059] Optionally, the vehicle is a crawler vehicle or a wheeled vehicle. When working on hard roads, a wheeled vehicle can be used, which is faster and more efficient. In swampy areas, a crawler vehicle can be used, which has better ability to pass and escape.

[0060] After adopting the above structure, the utility model has the following beneficial effects:

[0061] The front and rear vehicle body connection structure of the utility model can realize flexible connection of two or even more vehicle bodies. Compared with the traditional towing method, it not only plays a towing effect between adjacent vehicle bodies, but also can realize the individual change of the height, horizontal angle and roll angle between each vehicle body, fully adapting to the road conditions in swampy areas, and each vehicle body has a flexible activity angle.

[0062] In addition, adjacent vehicle bodies can also be connected to drive shafts to achieve transmission effects, especially two-section tracked vehicles can achieve four-wheel drive effects, with better passing performance and escape performance. In addition, there are driving components on the connecting rod, which can use the driving force to achieve a lateral twisting effect between the two vehicle bodies, thereby improving the vehicle's escape ability.

[0063] In an environment with more complicated road conditions, vehicles with double-section bodies have better passing ability and carrying capacity. When both double-section bodies have driving force, the vehicle has a better ability to get out of trouble.

[0064] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
