Description

Technical Field

[0002] In order to improve transportation efficiency, trailers in related technologies often serve as a mother vehicle to transport another smaller sub-vehicle to reduce the situation of traveling to the destination empty-handed. When the tractor is used as a mother vehicle to transport the sub-vehicle, the mother vehicle will shake due to poor road conditions.

For this reason, the trailer fixing structure of the sub-vehicle is rigidly connected and fixed, and the trailer fixing structure itself cannot be disassembled. Although it can reduce shaking, the trailer fixing structure cannot be disassembled, which will result in poor comfort in the sub-vehicle cab. Utility Model Content

[0035] In the description of the present invention, "first feature" or "second feature" may include one or more of the features.

[0036] In the description of the present invention, "plurality" means two or more.

[0037] The trailer fixing structure 1 according to an embodiment of the present utility model will be described below with reference to the accompanying drawings.

[0038] like Figure 1-Figure 6 As shown, the trailer fixing structure 1 according to the embodiment of the utility model includes: a suspension mechanism 100 , a clamping arm 200 , and a gantry 300 .

[0039] The suspension mechanism 100 includes a left suspension mechanism and a right suspension mechanism, and the left suspension mechanism 100 and the right suspension mechanism are respectively installed on the frame longitudinal beams on both sides and the tops of the left suspension mechanism and the right suspension mechanism. The clamping arm 200 includes a left clamping arm and a right clamping arm, and the left clamping arm 200 is installed on the left suspension mechanism 100, and the right clamping arm 200 is installed on the right suspension mechanism 100. The gantry 300 is located between the left suspension mechanism 100 and the right suspension mechanism 100, and the left clamping arm is detachably clamped on the left side of the gantry 300, and the right clamping arm is detachably clamped on the right side of the gantry 300.

[0040] For example, the trailer fixing structure 1 is applied to a mother-carriage vehicle towed by a trailer. One of the vehicles (trailer) is the mother vehicle 10, and the other vehicle is the child vehicle 20. The child vehicle 20 is installed in the compartment of the mother vehicle 10 and is lifted and transported by the mother vehicle 10. The mother vehicle 10 and the child vehicle 20 can both be trailers. During the process of the mother vehicle 10 transporting the child vehicle 20, the chassis of the child vehicle 20 remains fixed to the mother vehicle 10, and the cab of the child vehicle 20 is fixed to the frame longitudinal beam of the chassis of the child vehicle 20 through the trailer fixing structure 1, thereby ensuring that the cab of the child vehicle 20 also remains fixed to the mother vehicle 10.

[0041] In some embodiments, the trailer fixing structure 1 is a detachable structure. When the sub-trolley 20 is transported by the mother vehicle 10, the trailer fixing structure 1 on the sub-trolley 20 is clamped to the gantry 300 by the clamping arm 200. The gantry 300 is fixed to the cab of the sub-trolley 20 and the suspension mechanism 100 is fixed to the frame longitudinal beam of the chassis of the sub-trolley 20. At this time, the chassis of the sub-trolley 20 and the cab of the sub-trolley 20 are both fixed to the carriage of the mother vehicle 10.

[0042] When the sub-vehicle 20 is no longer transported and is driven alone, the clamping arm 200 can be disassembled, and the suspension mechanism 100 and the gantry 300 are no longer restricted by the clamping arm 200, and only a part of the bolt connection structure is retained at the bottom of the suspension mechanism 100 and the gantry 300. Thus, there is a certain amount of space for movement between the chassis of the sub-vehicle 20 and the cab of the sub-vehicle 20, reducing the rigid connection between the cab and the frame of the vehicle chassis, and improving the comfort in the cab.

[0043] According to the trailer fixing structure 1 of the embodiment of the utility model, the clamping arm 200 is constructed by the trailer fixing structure 1 to clamp the left and right sides of the fixed gantry 300, and the clamping arm 200 can adjust the tightness of the clamping gantry 300. When the clamping arm 200 is required to connect the suspension mechanism 100 and the gantry 300, the clamping arm 200 can be tightly clamped on the opposite sides of the gantry 300, and the cab and the frame longitudinal beam maintain a high connection stability. The cab and the frame of the sub-car 20 are fixedly connected without large shaking. The stability of the vehicle during transportation is high, and the cab of the sub-car 20 will not contact and collide with the inner wall of the mother car 10, avoiding wear on the car paint.

[0044] In addition, the clamping arm 200 has a detachable function. When the sub-vehicle 20 is traveling alone, the clamping arm 200 can be removed, and only the gantry 300 and the suspension structure are used to support and connect. Compared with the method of fixed connection between the gantry 300 and the suspension mechanism 100 in the related art, the clamping arm 200 has a detachable function. After the clamping arm 200 is removed, the trailer fixed structure 1 is only connected to the frame longitudinal beam and the cab by the suspension mechanism 100 and the gantry 300. The deformation space between the cab and the frame longitudinal beam is larger, and the personnel in the cab will not feel the vibration transmitted from the engine and the road surface, and the comfort is higher.

[0045] Therefore, the trailer fixing structure 1 according to the embodiment of the utility model has the advantages of strong disassembly and assembly, good vehicle body stability, and avoidance of paint surface damage.

[0046] In some specific embodiments of the present invention, Figure 6 As shown, the left clamping arm and the right clamping arm each include: a connecting arm 210 , a first half hoop 220 and a second half hoop 230 .

[0047] One end of the connecting arm 210 is connected to the suspension mechanism 100. The first half hoop 220 and the second half hoop 230 are connected to the other end of the connecting arm 210 through a fastener 240. The first half hoop 220 and the second half hoop 230 are respectively located on opposite sides of the gantry 300. The fastener 240 is suitable for adjusting the distance between the first half hoop 220 and the second half hoop 230 to tighten and separate from the gantry 300.

[0048] For example, the cross section of the gantry 300 is configured to be circular, and the first half hoop 220 and the second half hoop 230 are respectively configured with a semicircular structure that matches the outer contour of the gantry 300. The fastener 240 is located on one side of the first half hoop 220 and the second half hoop 230 adjacent to the connecting arm 210, and the fastener 240 is sequentially penetrated through the connecting arm 210, the first half hoop 220 and the second half hoop 230, and the fastener 240 includes a bolt and an adjusting nut. By tightening the adjusting nut on the bolt, the first half hoop 220 and the second half hoop 230 adjust the distance between the two through the nut, so that the gantry 300 is clamped and fixed between the first half hoop 220 and the second half hoop 230. When the first half hoop 220 and the second half hoop 230 are installed on the gantry 300, the nut of the fastener 240 is loosened, the gantry 300 is inserted between the first half hoop 220 and the second half hoop 230, and then the nut is tightened so that the first half hoop 220 and the second half hoop 230 fasten the gantry 300.

[0049] Furthermore, if Figure 6 As shown, the first half hoop 220 is configured with an elongated hole 221 , and one end of the second half hoop 230 is configured with a latch 231 extending into and engaging with the elongated hole 221 .

[0050] The first half hoop 220 is constructed with a long hole 221 to allow the tongue 231 of the second half hoop 230 to pass through the first half hoop 220 and engage with the first half hoop 220. In this way, the first half hoop 220 and the second half hoop 230 are easier to assemble, and the first half hoop 220 and the second half hoop 230 are always kept as a whole to prevent the first half hoop 220 and the second half hoop 230 from separating.

[0051] In some specific embodiments of the present invention, Figure 3-Figure 5 As shown, the left suspension mechanism and the right suspension mechanism include: a lower bracket 110 , an upper bracket 120 and a vibration reduction mechanism 130 .

[0052] The lower bracket 110 is suitable for being installed on the longitudinal beam of the vehicle frame. The upper bracket 120 is suitable for being installed on the cab and is located above the bracket, and the connecting arm 210 is connected to the upper bracket 120 through a pin. The damping mechanism 130 is connected to the lower bracket 110 and the upper bracket 120 respectively.

[0053] The lower bracket 110 and the upper bracket 120 are connected to the frame longitudinal beam and the cab respectively. The lower bracket 110 and the upper bracket 120 are connected to reduce vibration by a vibration reduction mechanism 130, thereby reducing vibration between the cab and the frame longitudinal beam.

[0054] Furthermore, if Figure 3-Figure 5 As shown, the lower support 110 includes an outer arm portion 111 and an inner arm portion 112. The outer arm portion 111 is connected to the outer side of the gantry 300, and the vibration reduction mechanism 130 is connected to the outer arm portion 111. The inner arm portion 112 is connected to the outer arm portion 111, and the gantry 300 is installed on the inner arm portion 112.

[0055] The bottoms of the inner arm portion 112 and the outer arm portion 111 are connected, so that the lower bracket 110 forms a "U"-shaped structure, and the outer arm portion 111 on the outside is connected to the upper bracket 120 for vibration reduction by connecting the vibration reduction mechanism 130. The inner arm portion 112 on the inside provides an installation space for installing the gantry 300, ensuring that the lower bracket 110 and the gantry 300 are installed and fixed, and the upper bracket 120 and the gantry 300 are fixed by the clamping arm 200, ensuring that the frame and the cab of the sub-car 20 are fixed during transportation.

[0056] Furthermore, if Figure 4 and Figure 5 As shown, the vibration reduction mechanism 130 includes a longitudinal vibration reduction mechanism 131 and a lateral vibration reduction mechanism 132 .

[0057] The longitudinal vibration reduction mechanism 131 reduces vibration along the longitudinal direction between the outer arm portion 111 and the upper bracket 120, and one end of the longitudinal vibration reduction mechanism 131 is connected to the outer arm portion 111, and the other end is connected to the upper bracket 120. The lateral vibration reduction mechanism 132 reduces vibration along the lateral direction between the inner arm portion 112 and the upper bracket 120, and one end of the lateral vibration reduction mechanism 132 is connected to the inner arm portion 112, and the other end is connected to the upper bracket 120.

[0058] For example, the longitudinal vibration damping mechanism 131 and the transverse vibration damping mechanism 132 are both air springs, the angle between the longitudinal vibration damping mechanism 131 and the vertical direction is less than 45°, and the angle between the transverse vibration damping mechanism 132 and the horizontal direction is less than 45°. The transverse vibration damping mechanism 132 and the longitudinal vibration damping mechanism 131 are respectively connected by the outer support arm 111 and the inner support arm 112, so as to dampen the vibration of the lower bracket 110 and the upper bracket 120 in different directions, and the vibration of the chassis frame and the engine is difficult to be transmitted to the cab, thereby improving the comfort of the people in the cab.

[0059] In some specific embodiments of the present invention, a bending section 211 is constructed in the middle of the connecting arm 210 , and the bending section 211 gradually bends backward from one end of the connecting arm 210 to the other end of the connecting arm 210 , so that the gantry 300 avoids the vibration reduction mechanism 130 .

[0060] The connecting arm 210 forms an “S”-shaped bending structure by constructing the bending section 211 , so that the gantry 300 is located behind the vibration reduction mechanism 130 , avoiding the vibration reduction mechanism 130 , and preventing the gantry 300 from interfering with the vibration reduction mechanism 130 .

[0061] In some specific embodiments of the present invention, both ends of the connecting arm 210 are constructed with reinforcing ribs 212 connected to the bending section 211 .

[0062] For example, the reinforcing rib 212 is perpendicular to the surface of the connecting arm 210, and the reinforcing rib 212 at one end of the connecting arm 210 and the reinforcing rib 212 at the other end of the connecting arm 210 are respectively formed on two opposite sides of the connecting arm 210. The reinforcing rib 212 provides a reinforcing structure in the thickness direction of the connecting arm 210 to improve the force strength of the connecting arm 210.

[0063] In some specific embodiments of the utility model, the trailer fixing structure 1 further includes: a plurality of harness fixing assemblies 400, which are mounted on the gantry 300 and arranged at intervals along the top of the gantry 300. The arrangement direction of the plurality of harness fixing assemblies 400 is the same as the routing direction of the vehicle harness, and the vehicle harness extends along the plurality of harness fixing assemblies 400 when passing through the trailer fixing structure 1 and is fixed by the harness fixing assemblies 400. For example, the harness fixing assembly 400 includes a bracket portion and a harness tie, the bracket portion is connected to the gantry 300, and the harness tie is passed through the bracket portion and bundles the harness to ensure the neat arrangement of the vehicle harness.
