Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.
[0035] The embodiment of the present application provides a vehicle. It should be noted that the vehicle in the present application may refer to a large car, a small car, a special-purpose car, etc. For example, according to the vehicle type, the vehicle in the present application may be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV) or other vehicle types. Generally, a vehicle is provided with wheels, a power source, and a transmission system arranged between the wheels and the power source. The transmission system can transmit the power provided by the power source to the wheels, so that the wheels rotate, thereby driving the vehicle to travel.
[0036] It should be noted that in the embodiments of the present application, the type of the power source of the vehicle is not limited. For example, for a fuel vehicle, the power source may refer to a fuel engine such as a gasoline engine or a diesel engine; for an electric vehicle, the power source may refer to an electric motor; for a hybrid vehicle, the power source may refer to an engine or an electric motor; for a vehicle powered by other means, the power source may refer to a device that generates power.
[0037] The vehicle provided in the embodiment of the present application includes a body structure, which specifically refers to the main frame of the vehicle and the corresponding structural parts connected to the main frame; wherein the main frame of the vehicle generally includes a body frame constructed of a steel structure, and the corresponding structural parts connected to the main frame of the vehicle may include various panels, brackets, etc. fixed to the body frame by welding, locking, snap connection, pin connection, etc. The body structure may form multiple chambers such as a compartment, a front compartment, and a rear compartment, thereby providing a storage space and a load-bearing installation foundation, so that components such as a power source, a transmission system, a suspension, and wheels can be assembled at corresponding positions on the body structure.
[0038] On this basis, the vehicle provided by the present application is a modified vehicle formed by splicing different vehicle models, specifically including a first target vehicle body and a second target vehicle body. The vehicle model of the first target vehicle body is different from that of the second target vehicle body, and the first target vehicle body and the second target vehicle body have different size specifications in the length direction. Therefore, it is necessary to remove the incompatible parts of the first target vehicle body and the second target vehicle body by cutting, and splice the remaining parts to form a complete modified vehicle. Specifically, refer to Figure 1 and Figure 2In actual operation, it is necessary to cut off the rear part of the rear floor welding assembly of the first target body 1, and splice the front side reserved part of the first target body 1 with the side of the second target body to finally form a complete modified vehicle; wherein, Figure 1 is a schematic diagram of the structure of the first target vehicle body 1 before cutting, Figure 2 It is a schematic diagram of the structure of the first target vehicle body 1 after cutting.
[0039] As described in the background art, the above-mentioned cutting process often cuts off the original rear tow hook installation point on the first target vehicle body 1, resulting in the final modified vehicle being unable to use the rear tow hook to fix the vehicle, thereby failing to smoothly conduct bench testing.
[0040] Based on the above problems, refer to Figure 2 After analyzing the modified vehicle, the researchers of the present application found that the rear end portion of the rear floor side beam 11 of the first target vehicle body 1 after cutting was exposed on the rear side of the first target vehicle body 1, and the shape of the rear end portion of the rear floor side beam 11 was convenient for connection with other structural parts. Therefore, the researchers of the present application creatively proposed the idea of quickly connecting the rear tow hook to the exposed rear floor side beam 11 through the corresponding transition structure after the first target vehicle body 1 was cut, so as to solve the problem of the original rear tow hook installation point being cut off.
[0041] Based on the above ideas, refer to Figures 3 to 7 The embodiment of the present application provides a rear tow hook structure, including a connecting plate assembly 3, a bottom plate 4 and a rear tow hook body 5; the connecting plate assembly 3 is used to connect with the rear end of the rear floor side beam 11 of the first target vehicle body 1 after cutting; the bottom plate 4 is connected to the connecting plate assembly 3; the bottom plate 4 is used to connect with the rear panel 2 of the second target vehicle body, so that the rear panel 2 and the body of the first target vehicle body 1 are enclosed to form a combined vehicle body; the rear tow hook body 5 is detachably connected to the bottom plate 4.
[0042] In this embodiment, the connecting plate assembly 3 may include a plurality of plates arranged in a preset manner, and the specific structural form of the connecting plate assembly 3 may be specifically set according to the shape and size of the rear end portion of the rear floor side beam 11. For example, all or part of the plates in the connecting plate assembly 3 may be fitted correspondingly to the side walls of the rear floor side beam 11, and then the plates may be fixed to the corresponding side walls on the rear floor side beam 11 by locking, riveting, snap-fitting, welding, etc. In actual operation, it is only necessary to ensure that the connecting plate assembly 3 can be conveniently and firmly connected to the rear end portion of the rear floor side beam 11, and the specific structural form and connection method of the connecting plate assembly 3 are not limited here.
[0043] Several plates in the connecting plate assembly 3 can be fixed to the bottom plate 4 by welding, locking, riveting, etc. The rear panel 2 is a part of the side panel of the second target vehicle body, and the rear panel 2 can be fixed to the bottom plate 4 by locking, riveting, welding, etc. The rear towing hook body 5 can be detachably connected to the bottom plate 4 by locking, riveting, snap connection, etc. In the above connection operation, on the one hand, the bottom plate 4 can connect the multiple plates in the connecting plate assembly 3 to form a whole and provide installation space for the rear towing hook body 5; on the other hand, since there is a certain angle deviation between the rear floor side beam 11 of the first target vehicle body 1 and the rear panel 2 of the second target vehicle body, the bottom plate 4 can also be used as an adapter to achieve the docking of the rear floor side beam 11 and the rear panel 2, and thereby achieve the connection and fixation between the cut body of the first target vehicle body 1 and the side panel of the second target vehicle body.
[0044] In actual operation, the connecting plate assembly 3 can be pre-connected and fixed to the base plate 4 to form a whole, and then the connecting plate assembly 3 can be connected and fixed to the rear end of the rear floor side beam 11 of the cut first target vehicle body 1, and then the rear panel 2 of the second target vehicle body can be connected and fixed to the base plate 4, so that the rear panel 2 and the body part of the first target vehicle body 1 are enclosed to form a complete combined vehicle body (that is, a modified hybrid vehicle); and if it is necessary to conduct a bench test on the combined vehicle body later, it is only necessary to connect the rear tow hook body 5 to the base plate 4; after the bench test is completed, the rear tow hook body 5 can be removed from the base plate 4.
[0045] It can be seen that the rear tow hook structure provided in the present embodiment, utilizing the transition structure formed by the connecting plate assembly 3 and the bottom plate 4, can conveniently connect the rear tow hook body 5 to the rear floor side beam 11 of the first target vehicle body 1 after cutting, and at the same time, the second target vehicle body and the first target vehicle body 1 can be spliced together through the connection between the rear panel 2 and the bottom plate 4. Therefore, while completing the vehicle modification, the rear tow hook body 5 can also be used to fix the modified vehicle, so that the modified vehicle can be smoothly bench tested later.
[0046] On this basis, in some embodiments of the present application, refer to Figures 3 to 7 The connecting plate assembly 3 is in a frame structure. The connecting plate assembly 3 is arranged around the rear end of the rear floor side beam 11. There are at least two relatively arranged connection points between the connecting plate assembly 3 and the rear floor side beam 11.
[0047] In this embodiment, the frame structure can be formed by enclosing a plurality of plate bodies in the connecting plate assembly 3; by setting the connecting plate assembly 3 as a frame structure surrounding the rear end of the rear floor side beam 11, the rear floor side beam 11 can be better utilized to limit the connecting plate assembly 3 from all directions. By setting the number of connection points between the connecting plate assembly 3 and the rear floor side beam 11 to two or more, and there are at least two relatively arranged connection points, the connection strength between the connecting plate assembly 3 and the rear floor side beam 11 can be increased. Among them, there are at least two relatively arranged connection points between the connecting plate assembly 3 and the rear floor side beam 11, which can specifically refer to the upper side and the lower side of the connecting plate assembly 3 being connected to the rear floor side beam 11 respectively, and / or the left side and the right side of the connecting plate assembly 3 being connected to the rear floor side beam 11 respectively, which is not limited here.
[0048] Based on the above arrangement, the connection stability between the connecting plate assembly 3 and the rear floor side beam 11 can be jointly improved.
[0049] In some embodiments of the present application, reference Figure 3 and Figure 4 , the connecting plate assembly 3 includes a first connecting plate 31, a second connecting plate 32, a third connecting plate 33 and a fourth connecting plate 34;
[0050] The side of the first connecting plate 31, the side of the second connecting plate 32, the side of the third connecting plate 33, and the side of the fourth connecting plate 34 are respectively connected to the front side surface of the bottom plate 4, and the first connecting plate 31, the second connecting plate 32, the third connecting plate 33, and the fourth connecting plate 34 are connected to the four side walls of the rear floor side beam 11 one by one.
[0051] In this embodiment, the connecting plate assembly 3 is divided into four independent connecting plates, which can better adapt to the rear floor side beams 11 of different sizes. Specifically, in the actual application process, the outer contour of the rear floor side beam 11 is a rectangular example, such as Figure 4As shown, the first connecting plate 31 and the second connecting plate 32 can be fixed on the bottom plate 4 in advance to ensure that the first connecting part and the second connecting plate 32 are perpendicular to each other, and then the first connecting plate 31 and the second connecting plate 32 are respectively connected and fixed to the two adjacent side walls of the rear floor side beam 11, and the bottom plate 4 is made to fit the rear end surface of the rear floor side beam 11 to block the inner cavity of the rear floor side beam 11 through the bottom plate 4, so that the rear floor side beam 11 can be used to limit the movement freedom of the rear towing hook structure in the three orthogonal directions of up and down, left and right, and front and back, so as to achieve the preliminary positioning of the rear towing hook structure; then the third connecting plate 33 and the fourth connecting plate 34 are respectively connected and fixed to the other two adjacent side walls of the rear floor side beam 11, and the third connecting plate 33 and the fourth connecting plate 34 are fixed to the bottom plate 4, so as to achieve a stable connection between the rear towing hook structure and the rear floor side beam 11. This connection method can avoid the situation where there is a deviation in the matching dimensions between the actual connecting plate assembly 3 and the rear floor side beam 11, and ensure that the connecting plate assembly 3 and the bottom plate 4 can fit tightly with the corresponding side walls of the rear floor side beam 11.
[0052] In some embodiments of the present application, reference Figure 3 The first connecting plate 31 has a first main body 311 and a first bending portion 312, the second connecting plate 32 has a second main body 321 and a second bending portion 322, the third connecting plate 33 has a third main body 331 and a third bending portion 332, and the fourth connecting plate 34 has a fourth main body 341 and a fourth bending portion 342;
[0053] The first main body 311 , the second main body 321 , the third main body 331 , and the fourth main body 341 are connected to the four side walls of the rear floor side beam 11 in a one-to-one correspondence, and the first bending portion 312 , the second bending portion 322 , the third bending portion 332 , and the fourth bending portion 342 are welded to the bottom plate 4 .
[0054] Illustratively, the first connecting plate 31, the second connecting plate 32, the third connecting plate 33, and the fourth connecting plate 34 are all in an "L" shape with the main body and the bending portion perpendicular to each other, and the rear end portion of the rear floor side beam 11 is located in the area enclosed by the first main body 311, the second main body 321, the third main body 331, and the fourth main body 341. By providing the first bending portion 312, the second bending portion 322, the third bending portion 332, and the fourth bending portion 342, the first connecting plate 31, the second connecting plate 32, the third connecting plate 33, and the fourth connecting plate 34 can be conveniently welded and fixed to the bottom plate 4 in a state perpendicular to the bottom plate 4, thereby improving the connection stability between the connecting plate assembly 3 and the bottom plate 4.
[0055] In some embodiments of the present application, reference Figure 2 , Figures 3 to 7The first connecting plate 31 , the second connecting plate 32 , the third connecting plate 33 , and the fourth connecting plate 34 are connected to the four side walls of the rear floor side beam 11 in a one-to-one correspondence.
[0056] In this embodiment, the four connecting plates are connected and fixed to the four side walls of the rear floor side beam 11 in a one-to-one correspondence. In this way, the contact area between the connecting plates and the rear floor side beam 11 can be increased by using the cooperation between the planes, thereby improving the connection stability. Among them, the four connecting plates can be connected and fixed to the rear floor side beam 11 by riveting, threading, snap-on connection, etc., which are not limited here; taking the riveting method as an example, its operation is more flexible and convenient, and it is easier to adjust the position of the connecting plate during the connection process; specifically, after the first target vehicle body 1 is cut, a rivet hole 111 can be correspondingly opened at the rear end of the rear floor side beam 11 for the rivet to pass through, and the rivet hole 111 can be as follows Figure 2 As shown, multiple connections are provided on each side wall and are evenly spaced to improve connection strength and stability.
[0057] In some embodiments of the present application, reference Figure 5 The bottom plate 4 is locked with the rear panel 2 through the threaded fastener 7; this can improve the flexibility and convenience of the connection operation, and can make it easier to adjust the position and remove and replace the rear panel 2. The threaded fastener 7 may include bolts, nuts, etc., and the bottom plate 4 and the rear panel 2 may be provided with corresponding through holes or threaded holes that are compatible with the threaded fastener 7 to achieve threaded connection.
[0058] In some embodiments of the present application, reference Figure 5 The bottom plate 4 is rectangular, and connecting holes 41 are respectively opened at the four corners of the bottom plate 4. The threaded fasteners 7 pass through the connecting holes 41 one by one and are locked to the rear panel 2. Based on this structural setting, the connection points can be dispersed as much as possible to improve the connection stability between the bottom plate 4 and the rear panel 2.
[0059] In some embodiments of the present application, reference Figures 3 to 5 , and also includes a connecting sleeve 6, one end of which is connected to the base plate 4, and the other end of which is threadedly connected to the rear towing hook body 5.
[0060] In practical applications, due to the limited thickness of the bottom plate 4, if the rear towing hook body 5 is directly connected to the bottom plate 4, the contact area between the rear towing hook body 5 and the bottom plate 4 may be too small, making it difficult to ensure the connection stability of the rear towing hook body 5. Based on this problem, the present embodiment adds a connecting sleeve 6 corresponding to the bottom plate 4, and the rear towing hook body 5 is threadedly connected to the inner cavity of the connecting sleeve 6. Specifically, the inner wall of the connecting sleeve 6 is provided with an internal thread section 61; the rear towing hook body 5 has a threaded rod, which is screwed onto the internal thread section 61; in this way, while improving the connection convenience between the rear towing hook body 5 and the bottom plate 4, the height of the connecting sleeve 6 can also be used to increase the contact area between the rear towing hook body 5 and the bottom plate 4, thereby improving the connection stability of the rear towing hook body 5.
[0061] Preferably, a shoulder portion can be provided on the rear tow hook body 5, and the diameter of the shoulder portion is larger than the threaded rod portion; in the process of screwing the threaded rod portion into the inner cavity of the connecting sleeve 6, the axial movement of the rear tow hook body 5 can be limited by the abutment between the shoulder portion and the second end surface of the connecting sleeve 6, thereby achieving fixation between the rear tow hook body 5 and the connecting sleeve 6.
[0062] In some embodiments of the present application, reference Figures 3 to 5 One end of the connecting sleeve 6 is welded to the base plate 4 , and the connecting sleeve 6 extends backward from the rear side of the base plate 4 ; the orthographic projection of the connecting sleeve 6 on the front side of the base plate 4 is located within the enclosed area of the connecting plate assembly 3 .
[0063] Specifically, a positioning hole 42 may be provided on the bottom plate 4 to allow the first end of the connecting sleeve 6 to pass through the positioning hole 42, and the connecting sleeve 6 may be initially positioned using the positioning hole 42, and then the connecting sleeve 6 may be welded and fixed to the bottom plate 4. The orthographic projection of the connecting sleeve 6 on the front side of the bottom plate 4 is located within the enclosed area of the connecting plate assembly 3, and specifically, the orthographic projection of the connecting sleeve 6 on the front side of the bottom plate 4 is located within the accommodating area enclosed by the first connecting plate 31, the second connecting plate 32, the third connecting plate 33, and the fourth connecting plate 34; based on this structural setting, in the subsequent bench test stage, when applying force to the rear towing hook body 5, the force may be relatively uniformly applied to each connecting plate and each side wall of the rear floor side beam 11 in all directions, thereby improving the uniformity of the force of the entire rear towing hook assembly.
[0064] The serial numbers of the embodiments of the present application are only for description and do not represent the advantages and disadvantages of the embodiments. The above are only preferred embodiments of the present application, and do not limit the patent scope of the present application.
