[0049] Reference is made below to Figures 1-5 A vehicle frame assembly according to an embodiment of the present application is described.

[0050] As Figures 1-3 shown, in the present embodiment, the vehicle frame assembly comprises a vehicle frame, a mounting bracket 200 and a tow hook 500.

[0051] The vehicle frame comprises a crossbeam and a longitudinal beam 100, the crossbeam extending in the lateral direction, and the longitudinal beam 100 extending in the longitudinal direction, the crossbeam and the longitudinal beam 100 being overlapped to form a bottom frame of the vehicle.

[0052] The mounting bracket 200 is mounted on the longitudinal beam 100, and the mounting bracket 200 is used to mount the tow hook 500, because the tow hook 500 is generally used to tow a vehicle or an object from the rear of the vehicle, and mainly bears a pulling force in the longitudinal direction, the mounting bracket 200 is mounted on the longitudinal beam 100 so that the bearing capacity on the mounting bracket 200 can be effectively transmitted to the longitudinal beam 100, and then transmitted to the entire bottom frame through the longitudinal beam 100, and the pulling force is borne by the bottom frame together.

[0053] One of the mounting bracket 200 and the longitudinal beam 100 is provided with a plurality of preselected mounting position groups 110 with different heights, and the other of the mounting bracket 200 and the longitudinal beam 100 is connected with one of the plurality of preselected mounting position groups 110.

[0054] The trailer hook 500 is connected with the mounting bracket 200, and the relative height between the ball head 520 of the trailer hook 500 and the mounting bracket 200 is fixed. The preselected mounting position group 110 is a mounting position group preselected according to the height between the vehicle frame and the ground line and the relative height between the ball head 520 of the trailer hook 500 and the mounting bracket 200. In order to meet the requirements of regulations, a plurality of mounting position groups with different heights are set according to the height between the vehicle frame and the ground line of different vehicle models. The mounting bracket 200 and the other one of the longitudinal beams 100 are connected with a corresponding one of the plurality of preselected mounting position groups 110, so that the height between the ball head 520 of the trailer hook 500 and the ground line can be adjusted.

[0055] In the embodiment, the vehicle frame assembly can be at least one of the following structural forms:

[0056] Firstly, as shown in FIG. 1, the plurality of preselected mounting position groups 110 are arranged on the longitudinal beams 100. Figure 1

[0057] In the embodiment, the longitudinal beams 100 are provided with a plurality of preselected mounting position groups 110 with different heights. By mounting the mounting bracket 200 on different preselected mounting position groups 110, the height between the mounting bracket 200 and the ground line can be changed, and then the height between the ball head 520 of the trailer hook 500 and the ground line can be changed.

[0058] Secondly, the plurality of preselected mounting position groups 110 are arranged on the mounting bracket 200.

[0059] In the embodiment, the mounting bracket 200 is provided with a plurality of preselected mounting position groups 110 with different heights. By selecting different preselected mounting position groups 110 on the mounting bracket 200 to be connected with the longitudinal beams 100, the height between the mounting bracket 200 and the ground line can be changed, and then the height between the ball head 520 of the trailer hook 500 and the ground line can be changed.

[0060] It should be noted that the plurality of preselected mounting position groups 110 are arranged on the longitudinal beams 100 in the subsequent embodiments for further description. It can be understood that the corresponding technical features are also applicable to the embodiment in which the plurality of preselected mounting position groups 110 are arranged on the mounting bracket 200.

[0061] In actual implementation, the plurality of preselected mounting position groups 110 with different heights are arranged on one of the mounting bracket 200 and the longitudinal beams 100. According to the height between the vehicle frame and the ground line of the production vehicle model, one of the plurality of preselected mounting position groups 110 is determined. After the other one of the mounting bracket 200 and the longitudinal beams 100 is mounted on the corresponding preselected mounting position group 110, the height of the ball head 520 of the trailer hook 500 relative to the ground line is within the height range required by regulations in the full load state.

[0062] ​According to the vehicle frame assembly provided in the embodiments of this application, by setting multiple pre-selected mounting position groups 110, different pre-selected mounting position groups 110 can be selected according to the vehicle height during production to assemble the mounting bracket 200, thereby changing the distance between the trailer hook 500 and the ground, meeting the distance requirements between the trailer hook 500 and the ground when fully loaded, and improving the compatibility between the mounting bracket 200 and the trailer hook 500.

[0063] In some embodiments, the mounting position between the mounting bracket 200 and the trailer hitch 500 can be designed according to the height of the ball joint 520 of the trailer hitch 500 for Cross (hybrid) models. The bottom frame height of the Cross model is between that of SUV (sportutility vehicle) and Sedan (closed van) models. Therefore, the design is based on the height of the ball joint 520 of the trailer hitch 500 for Cross models so that the height of the ball joint 520 of the trailer hitch 500 can be adjusted to accommodate the bottom frame height of various different models by adjusting the mounting height between the mounting bracket 200 and the longitudinal beam 100.

[0064] like Figure 1 As shown, in this embodiment, the longitudinal beam 100 may be provided with three pre-selected mounting position groups 110 distributed along the height direction, corresponding to SUV models, Cross models and Sedan models from top to bottom.

[0065] like Figures 1 to 5 As shown, according to some embodiments of this application, the mounting bracket 200 may include a connecting bracket 300 and a mounting beam 400.

[0066] One of the connecting bracket 300 and the longitudinal beam 100 may be provided with multiple pre-selected mounting positions 110 of different heights, and the connecting bracket 300 may be connected to the longitudinal beam 100.

[0067] The connecting bracket 300 can be connected to the longitudinal beam 100, and a plurality of pre-selected mounting position groups 110 can be set in one of the connecting bracket 300 and the longitudinal beam 100, and the other of the connecting bracket 300 and the longitudinal beam 100 is connected to one of the plurality of pre-selected mounting position groups 110.

[0068] The mounting beam 400 can be connected to the rear end of the connecting bracket 300, and the trailer hook 500 is connected to the mounting beam 400.

[0069] The front end of the connecting bracket 300 can be connected to the longitudinal beam 100, and the rear end of the connecting bracket 300 can be connected to the mounting beam 400. The connecting bracket 300 and the mounting beam 400 can be connected by welding, and the trailer hook 500 can be connected to the mounting beam 400 by welding, so as to improve the installation strength of the mounting bracket 200 and the trailer hook 500.

[0072] By arranging a plurality of longitudinal beams 100 and distributing the plurality of longitudinal beams 100 in the transverse direction, the overall structural strength of the frame is improved, and the stress on the frame is more uniform and less likely to deform. The connecting bracket 300 can be provided with a plurality of connecting brackets 300 corresponding to the plurality of longitudinal beams 100, the plurality of connecting brackets 300 are connected to the corresponding plurality of longitudinal beams 100, and the rear ends of the plurality of connecting brackets 300 are connected to the mounting beam 400. It can be understood that the plurality can be two or more.

[0073] It should be further noted that the number of connecting brackets 300 can be less than the number of longitudinal beams 100, so that the plurality of connecting brackets 300 correspond to at least part of the plurality of longitudinal beams 100, so that each connecting bracket 300 can be connected to the longitudinal beam 100.

[0074] In this embodiment, the connecting bracket 300 can be provided with two, the rear ends of the two connecting brackets 300 are connected to the two ends of the mounting beam 400 in the transverse direction, so that the mounting beam 400 is indirectly connected to the two longitudinal beams 100 arranged in the transverse direction, and the mounting strength of the mounting beam 400 is guaranteed. The two connecting brackets 300 can be arranged symmetrically in the transverse direction.

[0075] According to the plurality of connecting brackets 300 in the embodiment of the present application, the plurality of connecting brackets 300 are arranged to enable the pulling force borne by the trailer hook 500 to be transmitted to the plurality of longitudinal beams 100 through the mounting beam 400, so that the plurality of longitudinal beams 100 jointly bear the pulling force, the structure is more stable, and the stress is more uniform.

By arranging a plurality of connecting holes 120, the stability of the connection between the connecting bracket 300 and the longitudinal beam 100 is improved, and the rotation of the connecting bracket 300 is prevented. The plurality refers to two or more.

[0078] In this embodiment, the pre-selected mounting position group 110 may include two connecting holes 120 arranged longitudinally at intervals.

This connection method can optimize the assembly space and make the assembly structure more stable.

[0082] The longitudinal beam 100 has two inner sidewalls. The connecting bracket 300 can be connected to one of the two inner sidewalls. When there are two connecting brackets 300, the two connecting brackets 300 are symmetrically arranged in the transverse direction to connect to the corresponding inner sidewall of the corresponding longitudinal beam 100, so as to ensure the overall structure is subjected to balanced forces.
