[0034] The directional terms used in the following description refer to the directions shown in the figures and are not intended to limit the specific structure of the trailer device and vehicle of this utility model. It should also be noted that, in the description of this utility model, unless otherwise specified or limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to fixed connection, detachable connection, or integral connection; and can be directly connected or indirectly connected. Those skilled in the art will understand the specific meaning of these terms in this utility model based on the specific circumstances.

[0035] The present application provides a trailer device and a vehicle, which can reduce the impact on the trailer device during the vehicle's travel and extend the service life of the trailer device.

[0036] In order to better understand this application, Figures 1-6 The trailer device and vehicle in the embodiments of the present application are described in detail.

[0037] See also Figure 1-Figure 5 According to an embodiment of the present application, a trailer device includes a first connecting component and a second connecting component. The first connecting component is movably connected to the second connecting component, and the first connecting component can move on the second connecting component in a first direction.

[0038] The trailer device used in this embodiment is generally used on the body of a car. After one end of the trailer device is installed on the body, the other end is connected to the towed vehicle, so as to drive the towed vehicle to move. It can be understood that the device disclosed in this application can also be used to tow other devices such as ship hulls and aircraft, and this application does not impose any restrictions on this.

[0039] Specifically, in the embodiment of the present application, a first connecting assembly is connected to the towed device, and a second connecting assembly is connected to the vehicle. The first and second connecting assemblies are movably connected. When the towing device receives an impact in a first direction, such as the impact caused by the height difference of the road surface when the towing device is traveling over a bumpy road, the impact on the towing device is converted into kinetic energy, which enables the first assembly to move in the first direction. In the embodiment of the present application, the first direction refers to the height direction of the vehicle body perpendicular to the ground.

[0040] Thus, the trailer device moves in the first direction to achieve adjustment of the trailer device in the vehicle height direction, which can effectively alleviate the impact on the trailer device and extend the service life of the trailer device.

[0041] In an optional embodiment, the trailer device further includes a first buffer member, which is disposed between the first connecting component and the second connecting component and is suitable for alleviating collisions caused by movement of the first connecting component in the first direction.

[0042] Specifically, in this embodiment, the trailer device is also provided with a first buffer component, which is arranged between the first connecting component and the second connecting component. When the first connecting component moves along the first direction due to impact, the buffer component can effectively alleviate the collision between the first connecting component and the second connecting component, thereby avoiding the mechanical collision generated when the first connecting component moves in the first direction, and effectively extending the service life of the trailer component.

[0043] In an optional embodiment, the first connecting component includes a ball head 1 and a connecting seat 2, one end of the connecting seat 2 is fixedly connected to the ball head 1, and the other end is movably connected to the connecting component, and the connecting seat can move on the connecting component along a first direction.

[0044] Specifically, there can be multiple ball heads 1, which are installed on the connecting seat 2. The ball heads 1 are connected to the towed equipment to achieve towing of the towed equipment. The ball head 1 and the connecting seat 2 are fixedly connected by a connecting rod. In the embodiment of the present application, there are preferably two ball heads 1, and the two ball heads are respectively installed on two opposite surfaces in the first direction. This enables the towing device and the towed vehicle to be movable in the first direction, making installation more convenient. It is understandable that depending on the shape of the connecting seat, there can also be multiple ball heads. For example, if the connecting seat 2 is rectangular, there can be 5 cut heads. However, the connecting seat 2 must leave at least one surface to connect with the second connecting component. Therefore, the maximum number of ball heads 1 is the number of mounting surfaces of the connecting seat minus 1. The connecting seat 2 is used to fix the ball head 1 on the one hand and to connect with the second connecting component on the other hand. In this way, the connection between the first connecting component and the second connecting component is achieved.

[0045] In an optional embodiment, the second connecting assembly includes a first connecting member 4 and a second connecting member 11 , and the first connecting member 4 is connected to the connecting seat 2 .

[0046] Specifically, in the embodiment of the present application, the second connecting component includes two parts, a first connecting member 4 and a second connecting member 11. The first connecting member 4 and the second connecting member 11 can be cast as one piece or connected separately. The connection method can include welding, clamping, bonding, screwing, etc. It can also be that the first connecting member 4 and the second connecting member 11 are connected to another connecting member together, such as Figure 6 As shown, one end of the flat tube is connected to the first connector 4, and the other end is connected to the second connector 11, thereby forming an L-shaped connector. This application is not limited to this. The first connector and the second connector form an L-shaped connector, allowing the trailer device to move in multiple directions.

[0047] In an optional embodiment, a first spline is provided on the first connecting member 4, and a sliding groove is provided in the connecting seat 2. The number of the sliding grooves is equal to the number of the first spline key strips. The connecting seat 2 realizes a movable connection through the cooperation between the first spline and the sliding groove.

[0048] Specifically, in the embodiment of the present application, a first spline is provided on the first connector. The shape and number of the first spline can be adjusted according to the usage scenario, and this application does not impose any restrictions on this. A sliding groove is provided in the connecting seat 2, and the number of the sliding grooves is equal to the number of the first spline key strips. The connecting seat realizes a movable connection through the cooperation between the first spline and the sliding groove.

[0049] Therefore, through the cooperation between the first spline key bar and the connecting seat slide groove, the moving direction of the first connecting member 4 is fixed, so that when the trailer device is impacted in the first direction, it will only move along the first direction, avoiding the damage to the trailer device caused by the diffusion of the impact, and effectively extending the life of the trailer device.

[0050] In an optional embodiment, the device further includes a first limiting structure 7 and a first limiting member 10, wherein the first limiting structure 7 is arranged at one end of the first spline close to the second connecting member 11, and the second limiting structure 10 is arranged at one end of the first spline away from the second connecting member 11.

[0051] Specifically, a first limiting structure 7 is formed at one end of the first spline close to the second connecting member 11, and a second limiting structure 10 is provided at one end of the first spline away from the second connecting member 11. The radial length of the first limiting structure 7 and the second limiting structure 10 is greater than that of the first connecting member. The first limiting structure 7 and the second limiting structure 10 can be a gasket engaged with the first connecting member 4 or a nut threadedly connected to the first connecting member 4, or a step surface formed on the first connecting member 4. The first limiting structure 7 and the second limiting structure 10 can be made of metal material or elastic material such as rubber. As long as they can achieve a fixed limiting function, they can be applied to this embodiment to prevent the connecting seat 2 from being separated from the first spline due to impact.

[0052] In an optional embodiment, the first buffer members 8 / 9 are provided at both ends of the first spline.

[0053] Specifically, the first buffer member 8 / 9 is set at both ends of the first spline and is located between the first spline and the first limiting structure 7 and / or the second limiting structure 10. When the connecting seat 2 moves along the first direction on the first connecting member 4, it hits the first buffer member 8 / 9 to alleviate the impact. The first buffer member 8 / 9 can be a spring, a rubber elastic member, or other components for buffering. This application does not limit the type of the first buffer member 8 / 9. It is understandable that when the first limiting structure 7 and / or the second limiting structure 10 are elastic structures, the first buffer member can be reduced or eliminated. For example, when the first limiting structure 7 is a buffer structure, the first buffer member 8 / 9 can be omitted between the first limiting structure 7 and the first spline.

[0054] In an optional embodiment, the trailer device also includes a connecting arm 6, the second connecting member 11 is provided with a second spline, and a sliding groove is provided in the connecting arm 6. The number of the sliding grooves is equal to the number of spline key strips, and the connecting arm 6 is movably connected through the cooperation between the second spline and the sliding groove.

[0055] Specifically, the connecting arm 6 is externally connected to the trailer, and its internal structure is similar to the aforementioned connection base 2 and first connector 4, which will not be further described here. When the trailer is impacted in the second direction, the connecting arm 6 can move in the second direction, converting the impact into kinetic energy, thereby alleviating the impact on the trailer and extending the life of the trailer. In the embodiment of the present application, the second direction refers to the longitudinal direction of the vehicle body.

[0056] In an optional embodiment, the trailer device further includes a second buffer assembly 5 , one end of the second buffer assembly 5 is fixedly connected to the trailer arm 6 , and the other end extends away from the connecting arm.

[0057] Specifically, the second buffer assembly 5 is preferably a spring, one end of which is fixedly connected to the connecting arm 6 and the other end extends away from the connecting arm 6. In this way, when the connecting arm 6 moves in the second direction, when the spring 5 moves toward the first connecting member and contacts the first connecting member 4, the kinetic energy generated by the collision is absorbed by the compression of the spring 5, thereby alleviating the collision between the trailer arm 6 and the first connecting member 4 and extending the life of the trailer device.

[0058] In an optional embodiment, a stepped surface is formed on an end of the second connecting member 11 away from the first connection to limit the movement of the trailer arm 6 .

[0059] Specifically, such as Figure 6 As shown, a stepped surface is formed on the end of the second connecting member 11 facing away from the first connecting member 4. The stepped surface is preferably trapezoidal, but can also be a stepped surface with a radial length gradually increasing along the second direction away from the first connecting member 4. In this way, the displacement of the connecting arm 6 in the second direction can be limited, preventing the connecting arm 6 from being separated from the trailer device due to impact. It is understood that a third limiting structure can also be provided on the end of the second connecting member near the first connecting member to further limit the displacement of the connecting arm 6 in the second direction.

[0060] As can be seen from the present application, the trailer device, through its movable connection in the first and second directions, can effectively absorb impacts in the first and second directions, preventing the trailer device from being directly subjected to the impact and potentially causing damage to itself, thereby extending the service life of the trailer device. Furthermore, by providing a buffer structure on the first and second connecting members, it can mitigate collisions between the trailer loading compartments, further enhancing the buffering and shock-absorbing capabilities of the trailer device and increasing the overall service life of the trailer device. Thus, the trailer device achieves impact mitigation under various operating conditions, as specifically shown below:

[0061] When the trailer starts: the second connecting member 11 and the connecting arm 6 slide relative to each other through the spline, and the second buffer member 5 slows down the power transmission when the trailer starts. After the trailer starts, it drives the towed vehicle to start. At the same time, the spring 5 realizes starting buffering for the relative movement of the assembly of the first connecting member 4 and the second connecting member 11 and the trailer arm 6, reducing the power demand of the trailer to a certain extent.

[0062] When the trailer accelerates suddenly, the assembly formed by the first connecting member 4 and the second connecting member 11 slides relative to the trailer arm 6 through the spline. The stepped structure at the end of the spline of the second connecting member 11 acts as a limiter, and the spring 5 reduces the dynamic impact of the trailer acceleration.

[0063] When the trailer brakes suddenly: the assembly of the first connecting member 4 and the second connecting member 11 slides relative to the trailer arm 6 through the spline, and the spring 5 is compressed, which can slow down the impact of the inertial force of the towed vehicle transmitted to the trailer. At the same time, the stepped structure on the second connecting member 11 is used to limit the position, avoid sudden braking collision and achieve buffering.

[0064] When the trailer travels on different road conditions, acceleration and deceleration shocks will occur in the forward and backward directions. The relative sliding of the splines between the assembly of the first connecting member 4 and the second connecting member 11 and the trailer arm 6, as well as the tensile and compressive forces of the spring 5, can buffer the impact force in the direction of travel, thereby improving driving stability and safety, and protecting the reliability of the connection parts.

[0065] When there is a height difference between the towed vehicle and the trailer, the tow hook of the towed vehicle can be adjusted in height relative to the first connecting member 4 through the connecting seat 2. At the same time, during driving, on different road surfaces and working conditions, the relative height of the connection part between the trailer and the towed vehicle also changes. At this time, the connecting seat 2 and the first connecting member 4 are height-adaptive adjusted through the first spline, and the angle is adjusted in real time through the ball head. The first limiting structure 7 and the second limiting structure 10 are used at both ends of the spline to limit displacement, and the first buffer is used to reduce impact and achieve buffering.
