[0042] The front crossbeam assembly is a structure used to strengthen the front end of the vehicle frame. The front crossbeam assembly is connected between the left and right longitudinal beams of the vehicle frame. In addition to strengthening the stiffness of the front end of the vehicle frame, the front crossbeam assembly is also used to connect with other components of the vehicle. For example, the front crossbeam assembly is connected to the trapped vehicle through a tow hook, the front crossbeam assembly is connected to the anti-collision structure through an anti-collision beam bracket, and the front crossbeam assembly is connected to the vehicle frame longitudinal beam through a fixed bracket.

[0043] Components such as the above-mentioned tow hook, anti-collision beam bracket, and fixed bracket are designed separately and fixed to the front crossbeam assembly by means of welding, bolt connection, etc., resulting in a large number of structural parts, heavy weight, and complex assembly at the front end of the vehicle frame.

[0044] Combined Figures 1 to 4 As shown, according to a specific embodiment of the present application, a front crossbeam assembly of a vehicle frame is provided.

[0045] Specifically, the front crossbeam assembly of the vehicle frame includes: a towing structure 1, a first connection structure 2, and a second connection structure 3. The towing structure 1 is used to connect with other vehicles. There are two first connection structures 2, and the two first connection structures 2 are arranged at both ends of the towing structure 1 along the length direction of the towing structure 1. A connection seat 23 is provided at one end of each first connection structure 2 away from the towing structure 1, and the connection seat 23 is used to connect with the vehicle frame longitudinal beam. The first end of the second connection structure 3 is connected to the first connection structure 2, the second end of the second connection structure 3 is arranged away from the first connection structure 2, and the second end of the second connection structure 3 extends outward perpendicular to the length direction of the towing structure 1. The second end of the second connection structure 3 is used to connect with the anti-collision structure, and the anti-collision structure is used to prevent the front face of the cab from being scratched.

[0046] In the embodiment of the present application, the two first connection structures 2 are arranged at both ends of the towing structure 1 along the length direction of the towing structure 1, that is, in addition to being used to tow other vehicles, the towing structure 1 also serves as a part of the front crossbeam main body, reducing the number of structural parts, the overall weight, and the part assembly difficulty at the front end of the vehicle frame; in addition, the second connection structure 3 is connected to the first connection structure 2, that is, the second connection structure 3 is integrated on the first connection structure 2, further reducing the number of structural parts, the overall weight, and the part assembly difficulty at the front end of the vehicle frame. The towing structure 1, the first connection structure 2, the second connection structure 3, and the connection seat 23 in the present application are integrated together to jointly form the front crossbeam assembly of the vehicle frame, reducing the number of parts, the overall weight, and the part assembly difficulty of the front end structure of the vehicle frame.

[0047] Those skilled in the art can understand that the towing structure 1 is used to connect with the trapped vehicle to tow the vehicle. The anti-collision structure generally refers to a protective frame, a protective beam, etc. The anti-collision structure is located on the front side of the vehicle cab to protect the front face of the cab.

[0048] It should be noted that Figure 1The Z direction marked in the figure represents the vertical direction of the front crossbeam assembly of the vehicle frame, and the Y direction represents the horizontal direction of the front crossbeam assembly of the vehicle frame.

[0049] In an exemplary embodiment of the present application, the towing structure 1, the first connection structure 2, and the second connection structure 3 are integrally formed structures. There is no connection point between the towing structure 1 and the first connection structure 2, and there is no connection point between the first connection structure 2 and the second connection structure 3, that is, the stress concentration points on the front crossbeam assembly of the vehicle frame are reduced, thereby improving the overall stiffness of the front crossbeam assembly of the vehicle frame.

[0050] Specifically, the towing structure 1, the first connection structure 2, and the second connection structure 3 are integrally cast by a casting process. Among them, ductile iron is selected for integral casting. Ductile iron not only has high strength and high hardness, but also has high wear resistance and good vibration damping performance, which helps to improve the overall stability of the vehicle.

[0051] As an alternative implementation, to reduce the weight of the vehicle frame crossbeam assembly, lightweight materials such as aluminum alloy, magnesium alloy, or carbon fiber composite material can be used to manufacture some structural parts of the vehicle frame crossbeam assembly.

[0052] In an exemplary embodiment of the present application, the towing structure 1 is provided with a towing hole 11. The towing hole 11 penetrates through the main body of the towing structure 1 in the vertical direction. The towing hole 11 is used to tow the vehicle out of trouble. The towing hole 11 is used to pass a steel wire rope, and is connected to the trapped vehicle through the steel wire rope. Among them, the shape of the towing structure 1 is not limited, and it can be a rectangular structure, a cylindrical structure, etc.

[0053] The towing structure 1 is connected to the trapped vehicle through the towing hole 11. The processing technology of the towing hole 11 is simple and the cost is low. The setting of the towing hole 11 reduces the weight of the towing structure 1, thereby reducing the overall weight of the front crossbeam assembly of the vehicle. The towing hole 11 penetrates through the main body of the towing structure 1 to increase the acting area of the traction force, so as to reduce the probability of deformation of the towing structure 1 due to the traction force.

[0054] Furthermore, a first accommodating cavity 12 is further provided on the main body of the towing structure 1. The first accommodating cavity 12 penetrates through the main body of the towing structure 1 in the horizontal direction. The towing hole 11 penetrates through and is arranged on at least one side wall of the first accommodating cavity 12 in the vertical direction. Among them, the shape of the first accommodating cavity 12 is not limited, and it can be rectangular, circular, etc. The setting of the first accommodating cavity 12 reduces the weight of the towing structure 1, and further reduces the overall weight of the front crossbeam assembly of the vehicle.

[0055] Such as Figure 1 、 Figure 2As shown, the main body of the towing structure 1 is a rectangular structure, and the first accommodating cavity 12 is a rectangular structure. The first accommodating cavity 12 penetrates the main body of the towing structure 1 in the horizontal direction, and the edges of the first accommodating cavity 12 are all rounded to reduce the stress concentration at the edges of the first accommodating cavity 12. The towing hole 11 penetrates vertically through the top wall and the bottom wall of the first accommodating cavity 12.

[0056] When rescuing a trapped vehicle, a steel wire rope can be directly threaded into the towing hole 11, connected to the trapped vehicle through the steel wire rope, and tow the trapped vehicle.

[0057] When rescuing a trapped vehicle, a towing pin shaft can be threaded into the towing hole 11, and part of the towing pin shaft is exposed in the first accommodating cavity 12. The steel wire rope is sleeved on the towing pin shaft exposed in the first accommodating cavity 12, connected to the trapped vehicle through the steel wire rope, and tow the trapped vehicle.

[0058] In another exemplary embodiment of the present application, the towing structure 1 has a second accommodating cavity 13 with one end open. The second accommodating cavity 13 penetrates the main body of the towing structure 1 in the horizontal direction. A towing mechanism 14 is provided at the opening of the second accommodating cavity 13. The towing mechanism 14 has a towing position in a locked state and an avoidance position in an unlocked state. The towing mechanism 14 is used to tow the vehicle out of trouble. The second accommodating cavity 13 is used to thread a steel wire rope and connect it to the trapped vehicle. Among them, the shape of the second accommodating cavity 13 is not limited and can be rectangular, circular, etc. The towing mechanism 14 is provided to facilitate placing the steel wire rope in the second accommodating cavity 13.

[0059] As Figure 4 shown, a second accommodating cavity 13 is provided in the middle of the towing structure 1. The second accommodating cavity 13 penetrates the main body of the towing structure 1 in the horizontal direction. The opening of the second accommodating cavity 13 can be provided on the top wall of the second accommodating cavity 13 or on the bottom wall of the second accommodating cavity 13. The towing mechanism 14 can be connected to the inner wall of the second accommodating cavity 13 or to the outer wall of the second accommodating cavity 13.

[0060] Specifically, taking the example where the opening of the second accommodating cavity 13 is provided on the top wall of the second accommodating cavity 13 and the traction mechanism 14 is connected to the outer top wall of the second accommodating cavity 13 for description. The traction mechanism 14 includes: a wrench 141, a first hook 142, a torsion spring, and a second hook 143. The wrench 141 is hinged to a hinge seat on the outer top wall of the second accommodating cavity 13 through a pin shaft. The hinge seat is located on the first side of the opening. The second hook 143 is connected to the outer top wall of the second accommodating cavity 13, and the second hook 143 is located on the second side of the opening. The first hook 142 is rotatably connected to the wrench 141. The first hook 142 has a locking state of being hooked to the second hook 143 and an unlocking state of being separated from the second hook 143. The first end of the torsion spring is connected to the outer top wall of the second accommodating cavity 13, and the second end of the torsion spring is connected to the wrench 141. When the wrench 141 is in the pressed state, the torsion spring is in the initial state, that is, the wrench 141 can be easily pressed down to hook and lock the first hook 142 and the second hook 143. When the wrench 141 is in the lifted state, the torsion spring is in the twisted state, that is, it is necessary to lift the wrench 141 with effort to disengage the first hook 142 from the second hook 143. The setting of the torsion spring is to prevent the first hook 142 and the second hook 143 from being disengaged due to road bumps.

[0061] When rescuing a trapped vehicle, lift the wrench 141 to open the opening of the second accommodating cavity 13, and insert a steel wire rope through the opening so that the steel wire rope is sleeved on the traction mechanism 14 or on the bottom wall of the second accommodating cavity 13, and connect the steel wire rope to the trapped vehicle to tow the trapped vehicle.

[0062] As an alternative implementation, only the second accommodating cavity 13 is provided in the middle of the towing structure 1, and the second accommodating cavity 13 penetrates the main body of the towing structure 1 in the horizontal direction. When rescuing a trapped vehicle, the steel wire rope can be directly threaded through the second accommodating cavity 13, connected to the trapped vehicle through the steel wire rope, and tow the trapped vehicle.

[0063] In an exemplary embodiment of the present application, the first connection structure 2 is a hollow structure. Setting the first connection structure 2 as a hollow structure is equivalent to reducing the weight of the first connection structure 2 and further reducing the overall weight of the vehicle front cross member assembly. Among them, the shape of the first connection structure 2 is not limited and can be a rectangular structure, a cylindrical structure, etc.

[0064] Further, the first connection structure 2 includes: a first connection segment 21 and a second connection segment 22. The first end of the first connection segment 21 is connected to the towing structure 1. The first connection segment 21 is provided with a plurality of first weight-reducing holes 211, and the plurality of first weight-reducing holes 211 penetrate through the main body of the first connection segment 21 in the horizontal direction. The first end of the second connection segment 22 is connected to the second end of the first connection segment 21. The end of the second end of the second connection segment 22 is connected to the connection seat 23, and the second connection structure 3 is connected to a part of the outer peripheral surface of the second connection segment 22; wherein, the second connection structure 3 has a first connection surface, the connection seat 23 has a second connection surface, and the plane where the first connection surface is located is perpendicular to the plane where the second connection surface is located. A plurality of first weight-reducing holes 211 are provided in the Y direction of the first connection segment 21 to reduce the weight of the first connection structure 2. The second connection segment 22 is connected to the anti-collision structure through the second connection structure 3, and the second connection segment 22 needs to bear the acting force in the Y direction, so no weight-reducing holes are provided in the Y direction of the second connection segment 22.

Each group of first weight-reducing holes 211 has two first weight-reducing holes 211, and the two first weight-reducing holes 211 in each group are arranged at intervals along the thickness direction of the first connection segment 21.

The second connection segment 22 is a cylindrical structure, and the second connection segment 22 is connected between the first connection segment 21 and the connection seat 23.

Part of the connection seat 23 extends outward along the radial direction of the first connection main body 221, and another part of the connection seat 23 extends inward along the radial direction of the first connection main body 221 to the hollow structure. Wherein, the surface of the connection seat 23 away from the first connection segment 21 forms a second connection surface 231.

[0067] As Figure 1As shown, the first connecting body 221 is connected between the first connecting section 21 and the connecting seat 23. The first connecting body 221 has a hollow structure to reduce the weight of the second connecting section 22, so as to further carry out lightweight design for the front crossbeam assembly of the vehicle frame. A part of the connecting seat 23 extends outward in the radial direction of the first connecting body 221 to increase the area of the second connecting surface 231, thereby enhancing the contact area between the connecting seat 23 and the vehicle frame longitudinal beam.
