[0045] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0046] In related technologies, the trailer hook has an overall "L"-shaped structure, which adopts a round steel body and a conformal reinforcing plate structure. It is installed on the longitudinal beam of the vehicle frame through two mounting points. The trailer hook body adopts a round steel structure, which has a relatively weak overall load-bearing and towing force. When the trailer is subjected to greater force, it is prone to cracking and breakage. The mounting point layout is simple, which is disadvantageous in dealing with diverse towing loads under extreme conditions.

[0047] Based on this, this application proposes a trailer hitch, which is installed on the longitudinal beam of the vehicle frame assembly and located in front of the rear anti-collision beam in the vehicle frame assembly. The trailer hitch includes a first trailer hitch connecting seat and a second trailer hitch connecting seat. The first trailer hitch connecting seat is located below the longitudinal beam and can be connected and engaged with the bottom wall of the longitudinal beam along a first direction. A trailer rope connecting part is formed at the bottom of the first trailer hitch connecting seat for connecting and engaging with a trailer rope. The second trailer hitch connecting seat is connected to the upper part of the first trailer hitch connecting seat and can be connected and engaged with the side wall of the longitudinal beam in the Y direction along a second direction. In the X-direction projection of the vehicle frame assembly, the first direction and the second direction are intersected.

[0048] Therefore, compared with the round steel structure, the trailer hook of this utility model embodiment has better structural strength and is less prone to breakage and deformation. The first trailer hook connecting seat is located below the longitudinal beam and can be connected and cooperated with the bottom wall of the longitudinal beam along the first direction F. The second trailer hook connecting seat is connected to the upper part of the first trailer hook connecting seat and can be connected and cooperated with the side wall of the longitudinal beam in the Y direction along the second direction. That is to say, the trailer hook of this utility model embodiment is connected and cooperated with both the bottom wall and the side wall of the longitudinal beam, resulting in a larger connection area and better connection strength. At the same time, the first trailer hook connecting seat and the second trailer hook connecting seat cooperate with the longitudinal beam in different directions, which can jointly distribute the force and resist the horizontal traction force in different directions, making it less likely to detach from the longitudinal beam. It can better cope with the diverse towing loads under extreme conditions.

[0049] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0050] You can refer to Figures 1 to 12 According to the present utility model embodiment, the trailer hook 100 can be a rear trailer hook, which can be installed on the longitudinal beam 200 of the frame assembly and located in front of the rear anti-collision beam 300 in the frame assembly.

[0051] The rear bumper beam 300 is a transverse structural component installed at the rear end of the vehicle frame assembly. When a vehicle collides, the rear bumper beam 300 can absorb the energy generated by the collision to protect the occupants and internal parts of the vehicle. At the same time, by installing the rear bumper beam 300 at the rear end, it also helps to improve the torsional stiffness of the entire vehicle frame assembly.

[0052] For example, the trailer hitch 100 may also be a front trailer hitch.

[0053] The tow hook 100 is fixed to the longitudinal beam 200 of the frame assembly, ensuring that traction force is directly transmitted to the vehicle frame for reliable towing of the entire vehicle. The tow hook 100 is located in front of the rear bumper beam 300 in the frame assembly, so that the rear bumper beam 300 can function normally in an accident without affecting the towing function of the tow hook 100.

[0054] You can refer to Figures 1 to 3 The trailer hitch 100 includes a first trailer hitch connecting seat 10 and a second trailer hitch connecting seat 20. The first trailer hitch connecting seat 10 is located below the longitudinal beam 200 and can be connected and engaged with the bottom wall of the longitudinal beam 200 along the first direction F1. A trailer rope connecting part 30 is formed at the bottom of the first trailer hitch connecting seat 10, which is used to connect and engage with the trailer rope 400. The second trailer hitch connecting seat 20 is connected to the upper part of the first trailer hitch connecting seat 10 and can be connected and engaged with the side wall of the longitudinal beam 200 in the Y direction along the second direction F2. In the X-direction projection of the frame assembly, the first direction F1 and the second direction F2 are intersected.

[0055] For example, the first trailer hook connector 10 and the second trailer hook connector 20 can be welded together, or the first trailer hook connector 10 and the second trailer hook connector 20 can be integrally formed.

[0056] For example, in the frame assembly, the first direction F1 can be parallel to the Z direction, and the second direction F2 can be parallel to the Y direction. In the X-direction projection of the frame assembly, the first direction F1 and the second direction F2 are intersecting. For example, the first direction F1 and the second direction F2 are perpendicular to each other; or, the angle between the first direction F1 and the second direction F2 is 85°, 80°, 75°, 70°, 65°, 60°, etc., without specific limitations.

[0057] You can refer to Figure 4 The first trailer hook connecting seat 10 is located below the longitudinal beam 200, and the trailer rope connecting part 30 is formed at the bottom of the first trailer hook connecting seat 10, that is, the trailer rope connecting part 30 is formed below the longitudinal beam 200. In this way, the trailer hook 100 is easy to use and can be used directly when needed.

[0058] According to an embodiment of the present invention, the trailer hook 100 includes a first trailer hook connecting seat 10 and a second trailer hook connecting seat 20. Compared with a round steel structure, it has better structural strength and is less prone to breakage and deformation. The first trailer hook connecting seat 10 is located below the longitudinal beam 200 and can be connected to the bottom wall of the longitudinal beam 200 along the first direction F1. The second trailer hook connecting seat 20 is connected to the upper part of the first trailer hook connecting seat 10 and can be connected to the side wall of the longitudinal beam 200 in the Y direction along the second direction F2. That is to say, the trailer hook 100 of the present invention is connected to both the bottom wall and the side wall of the longitudinal beam 200, resulting in a larger connection area and better connection strength. At the same time, the first trailer hook connecting seat 10 and the second trailer hook connecting seat 20 have different engagement directions with the longitudinal beam 200, which can jointly distribute the force and resist horizontal traction forces in different directions, making it less likely to detach from the longitudinal beam 200. It can better cope with diverse towing loads under extreme conditions.

[0059] According to some embodiments of this utility model, it can be referred to Figures 1 to 9 The first trailer hook connecting seat 10 includes a connecting plate segment 101, which is disposed opposite to and connected to the bottom wall of the longitudinal beam 200. The second trailer hook connecting seat 20 is connected to the connecting plate segment 101 and extends upward, and the second trailer hook connecting seat 20 is at least partially disposed opposite to the side wall of the longitudinal beam 200 in the Y direction.

[0060] The above technical solution, by setting the connecting plate segment 101 to be opposite to and connected to the bottom wall of the longitudinal beam 200, facilitates maximizing the contact area between the first trailer hook connecting seat 10 and the bottom wall of the longitudinal beam 200, thereby increasing the connection stability between the first trailer hook connecting seat 10 and the longitudinal beam 200. The second trailer hook connecting seat 20 extends upward and is at least partially opposite to the side wall of the longitudinal beam 200 in the Y direction, further maximizing the contact area between the second trailer hook connecting seat 20 and the side wall of the longitudinal beam 200, thus increasing the connection stability between the second trailer hook connecting seat 20 and the longitudinal beam 200.

[0061] In some embodiments, reference may be made to Figure 1 A clearance area 106 is formed on the front side of the connecting plate segment 101 and near the second trailer hook connecting seat 20. The clearance area 106 is used to avoid surrounding parts and prevent the connecting plate segment 101 from affecting the arrangement of surrounding parts.

[0062] For example, the second trailer hook connector 20 may include a first end and a second end. The first end is connected to the connecting plate segment 101 along the Z direction, and the second end is located on the side of the first end away from the connecting plate segment 101. Along the direction from the first end to the second end, the size of the second trailer hook connector 20 gradually decreases in the front-rear direction.

[0063] According to some embodiments of this utility model, it can be referred to Figure 1 and Figure 2 The first trailer hook connector 10 also includes an extension plate segment 102, which is connected to the rear of the connector plate segment 101 and extends downward and tilted to the rear side relative to the connector plate segment 101. The trailer rope connector 30 is connected to the extension plate segment 102.

[0064] In the above embodiment, the extension plate segment 102 is connected to the rear of the connecting plate segment 101 and extends downward and tilted to the rear relative to the connecting plate segment 101. The trailer rope connection portion 30 is connected to the extension plate segment 102. This allows the trailer rope connection portion 30 to be positioned as low and rearward as possible, making it easier for users to connect the trailer rope 400 and the trailer rope connection portion 30, and reducing the risk of interference from surrounding components during the connection process.

[0065] For example, one can refer to Figure 1 and Figure 2 The extension plate segment 102 may be provided with weight reduction holes 107 to reduce the weight of the first trailer hook connecting seat 10.

[0066] According to some embodiments of this utility model, it can be referred to Figure 1 and Figure 2 The first trailer hook connecting seat 10 also includes a reinforcing plate segment 103, which is connected to the connecting plate segment 101 on one side in the second direction F2 and connected to the extension plate segment 102. The reinforcing plate segment 103 extends downward from the connecting plate segment 101 and the extension plate segment 102.

[0067] In the above embodiments, the reinforcement plate segment 103 can increase the connection area between the trailer rope connection part 30 and the connecting plate segment 101, as well as the force transmission path between the trailer rope connection part 30 and the connecting plate segment 101, reducing the possibility of breakage between the trailer rope connection part 30 and the extension plate segment 102; at the same time, it also makes the overall structural strength of the entire first trailer hook connecting seat 10 better and less prone to deformation.

[0068] According to some embodiments of this utility model, it can be referred to Figure 1 and Figure 2 The first trailer hook connecting seat 10 is provided with two reinforcing plate sections 103. The two reinforcing plate sections 103 are respectively connected to the connecting plate section 101 on both sides of the second direction F2, so as to form a cavity structure 104 that is open to the downward side by the connecting plate section 101, the extension plate section 102 and the two reinforcing plate sections 103.

[0069] In other words, the two reinforcing plate segments 103 are spaced apart along the second direction F2 on both sides of the connecting plate segment 101. Exemplarily, the two reinforcing plate segments 103 may have the same shape and different dimensions.

[0070] In the above technical solution, the connecting plate segment 101, the extension plate segment 102, and the two side reinforcing plate segments 103 enclose and form a cavity structure 104, which can significantly improve the overall bending and torsional resistance of the first trailer hook connecting seat 10 and reduce the possibility of local deformation or tearing during towing. While ensuring strength, the design of the cavity structure 104 can reduce material usage, lower weight, and avoid redundant mass in a solid structure. The downward-opening cavity structure 104 allows water and debris to drain naturally, preventing long-term accumulation that could lead to corrosion of the first trailer hook connecting seat 10.

[0071] According to some embodiments of this utility model, it can be referred to Figure 1 and Figure 2 The connecting plate segment 101 is provided with a first mounting hole 1011 that extends through the first direction F1. The first mounting hole 1011 is used for the connecting member to pass through, so as to connect and fix the first trailer hook connecting seat 10 to the bottom wall of the longitudinal beam 200.

[0072] For example, the connector can be a bolt. For example, the connecting plate segment 101 and the longitudinal beam 200 can be connected by both connectors and welding to further improve the connection strength between the first trailer hook connecting seat 10 and the longitudinal beam 200. For example, the first direction F1 can be the up-down direction or the Z-direction of the vehicle.

[0073] The first trailer hook connector 10 is installed by using a connector that passes through the first mounting hole 1011 on the connecting plate section 101. This makes the installation operation easier and facilitates the later maintenance and replacement of the trailer hook 100.

[0074] According to some embodiments of this utility model, it can be referred to Figure 3 The trailer hook 100 is provided with a second trailer hook connecting seat 20, which is connected to the connecting plate segment 101 on one side in the second direction F2 and located on one side of the longitudinal beam 200 in the Y direction.

[0075] For example, a second trailer hitch connection seat 20 may be located on the inner side of the longitudinal beam 200 in the Y direction, to avoid components located on the outer side of the longitudinal beam 200; or, a second trailer hitch connection seat 20 may be located on the outer side of the longitudinal beam 200 in the Y direction, to avoid components located on the inner side of the longitudinal beam 200.

[0076] In the above technical solution, only one second trailer hook connecting seat 20 is set. In this way, the trailer hook 100 occupies a smaller space volume, which can better avoid interference between the trailer hook 100 and the peripheral parts of the longitudinal beam 200.

[0077] According to some embodiments of the present invention, the trailer hook 100 is provided with two second trailer hook connecting seats 20. The two second trailer hook connecting seats 20 are respectively connected to the two sides of the connecting plate segment 101 in the second direction F2, and are respectively located on the two sides of the longitudinal beam 200 in the Y direction.

[0078] In the above technical solution, the connection area between the trailer hook 100 and the longitudinal beam 200 is larger, and the connection stability is better; there are more force transmission paths between the trailer rope connection part 30 and the longitudinal beam 200, and the force is more dispersed, which helps to reduce the risk of the trailer hook 100 and the longitudinal beam 200 becoming detached.

[0079] According to some embodiments of this utility model, it can be referred to Figure 1 and Figure 2 The second trailer hook connecting seat 20 is provided with a second mounting hole 201 that extends along the second direction F2. The second mounting hole 201 is used for the connecting member to pass through, so as to connect and fix the second trailer hook connecting seat 20 to the longitudinal beam 200.

[0080] For example, the second direction F2 can be a left-right direction or the Y-direction of the vehicle. Exemplarily, the connector can be a bolt. Exemplarily, the second trailer hook connector 20 and the longitudinal beam 200 can be connected by both connectors and welding to further improve the connection strength between the second trailer hook connector 20 and the longitudinal beam 200.

[0081] The second trailer hook connector 20 is installed by using a connector that passes through the second mounting hole 201 on the second trailer hook connector 20. This makes the installation operation easier and facilitates the later maintenance and replacement of the trailer hook.

[0082] According to some embodiments of the present invention, the first trailer hook connecting seat 10 has a first connecting surface 105, the first connecting surface 105 is fitted to the bottom wall of the longitudinal beam 200, and the first direction F1 is perpendicular to the first connecting surface 105.

[0083] According to some embodiments of the present invention, the second trailer hook connecting seat 20 has a second connecting surface 202, the second connecting surface 202 is fitted to the side wall of the longitudinal beam 200, and the second direction F2 is perpendicular to the second connecting surface 202.

[0084] According to some embodiments of the present invention, the first direction F1 and the second direction F2 are arranged perpendicularly.

[0085] According to some embodiments of the present invention, the first trailer hook connecting seat 10 has a first connecting surface 105, which is fitted to the bottom wall of the longitudinal beam 200, and the first direction F1 is perpendicular to the first connecting surface 105. The second trailer hook connecting seat 20 has a second connecting surface 202, which is fitted to the side wall of the longitudinal beam 200, and the second direction F2 is perpendicular to the second connecting surface 202. The first direction F1 and the second direction F2 are perpendicular to each other.

[0086] For example, the first connecting surface 105 extends horizontally and the second connecting surface 202 extends vertically.

[0087] In the above technical solution, the first connecting surface 105 and the second connecting surface 202 are perpendicular to each other, which helps to increase the connection strength between the trailer hook 100 and the longitudinal beam 200, maximize the load-bearing capacity of the towing force, and make the overall structure of the trailer hook 100 more reliable.

[0088] According to some embodiments of the present invention, the first trailer hook connecting seat 10 and the second trailer hook connecting seat 20 are integrally formed.

[0089] For example, the first trailer hook connector 10, the second trailer hook connector 20 and the trailer rope connector 30 are integrally formed.

[0090] In other words, there is no seam between the first trailer hook connecting seat 10 and the second trailer hook connecting seat 20, which results in better structural strength and performance of the trailer hook 100. For example, the first trailer hook connecting seat 10 and the second trailer hook connecting seat 20 can be integrally forged.

[0091] In the above technical solution, the first trailer hook connecting seat 10 and the second trailer hook connecting seat 20 adopt an integrated design, which avoids the risks of stress concentration, fatigue cracks or loosening that are prone to occur at the welding or bolted connections in the case of a split design. Under stress, the load is transferred through continuous material rather than relying on the connection interface, thus improving the tensile / shear strength of the trailer hook. When the trailer swings or is towed at an angle, the integrated structure can more effectively resist torsional moments and avoid the fretting wear problem of the split structure.

[0092] According to some embodiments of this utility model, it can be referred to Figure 6 and Figure 8 The trailer rope connection part 30 extends downward from the first trailer hook connection seat 10 and has a third mounting hole 301 that is provided through in the second direction F2. The third mounting hole 301 is used to install the trailer rope 400.

[0093] The trailer rope connection part 30 of the above technical solution allows for sufficient operating space to be reserved on both sides of the trailer rope connection part 30 after installation, making it convenient for operators to install the trailer rope 400 on the trailer hook 100.

[0094] The second aspect of this utility model also proposes a vehicle frame assembly.

[0095] The chassis assembly according to an embodiment of the present invention includes a trailer hitch according to a first aspect of the present invention.

[0096] According to an embodiment of the present invention, the vehicle frame assembly includes a trailer hitch 100, which includes a first trailer hitch connecting seat 10 and a second trailer hitch connecting seat 20. Compared with a round steel structure, it has better structural strength and is less prone to breakage and deformation. The first trailer hitch connecting seat 10 is located below the longitudinal beam 200 and can be connected and engaged with the bottom wall of the longitudinal beam 200 along the first direction F1. The second trailer hitch connecting seat 20 is connected to the upper part of the first trailer hitch connecting seat 10 and can be engaged with the longitudinal beam 200 in the Y direction along the second direction F2. The side wall connection is such that the trailer hook 100 of this embodiment is connected to both the bottom wall of the longitudinal beam 200 and the side wall of the longitudinal beam 200, resulting in a larger connection area and better connection strength. At the same time, the first trailer hook connecting seat 10 and the second trailer hook connecting seat 20 have different cooperation directions with the longitudinal beam 200, which can jointly distribute the force and resist horizontal traction forces in different directions, making it less likely to detach from the longitudinal beam 200. This allows it to better cope with diverse towing loads under extreme conditions.

[0097] The second aspect of this utility model also proposes a vehicle.

[0098] The vehicle according to an embodiment of the present invention includes a frame assembly according to a second aspect of the present invention.

[0099] The vehicle according to an embodiment of the present invention includes a frame assembly, which includes a tow hook 100. The tow hook 100 includes a first tow hook connecting seat 10 and a second tow hook connecting seat 20. Compared with a round steel structure, it has better structural strength and is less prone to breakage and deformation. The first tow hook connecting seat 10 is located below the longitudinal beam 200 and can be connected and engaged with the bottom wall of the longitudinal beam 200 along a first direction F1. The second tow hook connecting seat 20 is connected to the upper part of the first tow hook connecting seat 10 and can be connected and engaged with the longitudinal beam 200 along a second direction F2. The Y-direction sidewall connection means that the trailer hook 100 of this embodiment is connected to both the bottom wall and the sidewall of the longitudinal beam 200, resulting in a larger connection area and better connection strength. At the same time, the first trailer hook connecting seat 10 and the second trailer hook connecting seat 20 have different engagement directions with the longitudinal beam 200, which can jointly distribute the force and resist horizontal traction forces in different directions, making it less likely to detach from the longitudinal beam 200. This allows it to better cope with diverse towing loads under extreme conditions.

[0100] It should be noted that the arrangement of the tow rope connection part 30 should ensure that the tow rope 400 can reach the following ranges: the angle between the uppermost position of the tow rope 400 and the horizontal line is 5°, and the angle between the lowermost position of the tow rope 400 and the horizontal line is 5° (refer to...). Figure 11 (You can refer to this.) Figure 12 The angle between the leftmost reachable position of the tow rope 400 and the vertical plane containing the center position of the tow rope connection 30 is 25°, and the angle between the rightmost reachable position of the tow rope 400 and the vertical plane containing the center position of the tow rope connection 30 is also 25°. This is to prevent the tow rope 400 from interfering with the rear bumper CAS surface 500 (CAS is an abbreviation for Computer Aided Styling) during towing, thus avoiding damage to the vehicle's rear bumper.
