Description

Technical Field

[0001] The utility model relates to the technical field of vehicles, and in particular to a towing device installation structure. Meanwhile, the utility model also relates to a vehicle provided with the towing device installation structure. Background Art

[0002] The automobile towing device mainly includes towing tools such as a towing hook (tow ring) and a towing rope or towing rod, which are mainly used for towing or traction when the vehicle breaks down or needs to be moved. The rear section of the rear floor longitudinal beam of the vehicle body usually provides an installation and fixing point for the towing device to ensure the installation strength and rigidity requirements of the towing device. The conventional towing device mounting structure is generally composed of the rear section of the rear floor longitudinal beam, the rear reinforcement plate of the longitudinal beam, the rear anti-collision beam reinforcement plate, the towing hook mounting tube, and the mounting tube reinforcement plate, and the towing device is connected to the rear longitudinal beam through the towing hook mounting tube. The towing device mounting structure of this structure requires multiple parts, has more structures, and is cumbersome to assemble.

[0003] In addition, the towing device is usually screwed on the longitudinal beam, and its traction force is transmitted to the rear section of the rear floor longitudinal beam through the trailer hook mounting tube. The trailer hook mounting tube and the mounting tube reinforcement plate need to be connected by two weldings, the mounting tube reinforcement plate and the longitudinal beam body also need to be connected by two weldings, and the longitudinal beam rear reinforcement plate and the rear anti-collision beam mounting reinforcement plate also need to be connected by two weldings. This structure has multiple two-welding connection positions, and two-welding is prone to cause deformation of parts, insufficient installation accuracy, and poor electrophoresis at the welding point. The rear section of the rear floor longitudinal beam is in the wet area of ​​the vehicle, and it is very easy to rust when it encounters water for a long time. Because the towing device needs to tow heavy objects, under the influence of each other, the parts are prone to breakage at the welding point, making the installation firmness of the towing device on the vehicle body poor.

[0039] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0040] In the description of the present utility model, it should be noted that the directional words such as "up, down, left, right, front, and back" used in the present embodiment are defined based on the up-down direction, left-right direction, and front-back direction of the automobile. Among them, the up-down direction of the automobile is also the height direction of the automobile (Z direction), the front-back direction of the automobile is also the length direction of the automobile (X direction), and the left-right direction of the automobile is also the width direction of the automobile (Y direction). In addition, the terms "first" and "second" are used only for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0041] In addition, in the description of the present invention, unless otherwise clearly defined, the terms "installation", "connection", "connection", and "connector" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood in combination with specific circumstances.

[0042] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0043] The automobile towing device is usually installed on both sides of the rear floor longitudinal beam of the load-bearing vehicle body. During the use of the towing device, the vehicle body mounting point is subjected to loads in three directions: X / Y / Z. As the towing mass increases, the load increases. Therefore, the rigidity, strength and fatigue performance of the towing device mounting structure are required to be higher. However, the towing device mounting structure in the prior art is usually welded from multiple parts, which has poor strength and is difficult to avoid the defects of the welding process itself, resulting in poor connection firmness between the towing device and the rear floor longitudinal beam of the vehicle body, resulting in poor installation firmness of the rear towing device on the vehicle body.

[0044] Based on the above situation, this embodiment particularly mentions a towing device installation structure, which has a simple structure and high strength, and can improve the installation firmness of the towing device on the vehicle body. In terms of overall structure, the towing device installation structure of this embodiment includes an integrally formed installation member 1. Among them, the installation member 1 includes a main body portion 101 and a mounting portion 102 connected to the main body portion 101. The main body portion 101 is located in the vehicle body longitudinal beam 2 and is fixedly connected to the vehicle body longitudinal beam 2. The mounting portion 102 extends from the hollow portion on the vehicle body longitudinal beam 2 and is used to fix the towing device on the vehicle body longitudinal beam 2.

[0045] The towing device installation structure of this embodiment, by forming the installation part 1 in one piece, does not need to weld multiple parts compared to the traditional structure, can simplify its structure, ensure its accuracy, and make it have better structural strength, thereby improving the installation firmness of the towing device and facilitating assembly. Compared with the traditional structure, it can also effectively solve the problem of the towing device being unstable due to deformation and rust of parts caused by double welding.

[0046] According to the above overall introduction, an exemplary structure of the towing device installation structure of this embodiment is referred to as Figures 1 to 6 As shown in, Figures 1 to 3 The diagram shows the assembly state of the mounting member 1 and the vehicle body longitudinal beam 2. Figures 4 to 6The specific structure of the mounting member 1 is shown. In addition, it should be mentioned that the vehicle body longitudinal beam 2 of this embodiment specifically refers to the vehicle body rear floor longitudinal beam, and since the vehicle body longitudinal beam 2 is generally arranged in two opposite positions on the left and right, the mounting members 1 of this embodiment are also arranged in two opposite positions on the left and right. The two mounting members 1 are respectively installed on the vehicle body longitudinal beam 2 on the corresponding side, and the towing device is connected to the two mounting members 1 at the same time. The specific structure of the towing device can refer to the prior art and will not be repeated here.

[0047] As a preferred embodiment, the mounting member 1 of this embodiment is cast from aluminum alloy. This design not only reduces the overall weight of the mounting member 1, but also has a high structural strength and good corrosion resistance. Figures 4 to 6 As shown in , as a preferred embodiment, the main body 101 follows the shape of the vehicle body longitudinal beam 2. That is to say, the shape, size and profile of the main body 101 closely match the structural characteristics of the vehicle body longitudinal beam 2. This arrangement helps to improve the overall structural strength, stability and safety of the vehicle, while ensuring the accurate installation and positioning of the mounting member 1. At the same time, this design is conducive to more accurate installation of the mounting member 1 on the vehicle body longitudinal beam 2, reducing installation errors and gaps, and reducing the relative movement and friction between the mounting member 1 and the vehicle body longitudinal beam 2, thereby reducing noise and vibration, and also facilitating the connection between the two.

[0048] like Figures 4 to 5 As shown, specifically, the body part 101 of this embodiment includes a bottom wall and side walls arranged on two opposite sides of the bottom wall, and the bottom wall and the side walls are connected to the vehicle body longitudinal beam 2 through connecting members. The connecting members include FDS screws 3, that is, the connecting members connecting the bottom wall and the side walls with the vehicle body longitudinal beam 2 can be all FDS screws 3, or part of them can be FDS screws 3, and the other part can be conventionally used screws or bolts. As a preferred embodiment, the connecting members connecting the bottom wall and the side walls with the vehicle body longitudinal beam 2 of this embodiment are all FDS screws 3.

[0049] Furthermore, in order to improve the connection strength, the side walls on both sides are connected to the vehicle body longitudinal beam 2 through two rows of FDS screws 3 arranged at intervals. At the same time, the rear end of the bottom wall is connected to the vehicle body longitudinal beam 2 through two FDS screws 3 arranged at intervals, and the front end is connected to the vehicle body longitudinal beam 2 through the FDS screws 3 arranged at the mounting portion 102. It can be understood that the provision of the FDS screws 3 at the mounting portion 102 can help improve the connection firmness between the mounting portion 102 and the vehicle body longitudinal beam 2, improve the load-bearing performance of this position, and prevent the mounting part 1 from being separated from the vehicle body longitudinal beam 2 due to the drag force on the mounting portion 102.

[0050] Among them, the FDS screw 3 (Flow Drill Screw) is a special self-tapping screw that creates a hole in the metal sheet by rotating and extruding, and simultaneously completes the formation of the thread and the connection of the material. This connection method does not require pre-drilling, so it can improve the installation efficiency and connection strength between the main body part 101 and the vehicle body longitudinal beam 2, and can effectively prevent the mounting part 1 from being detached from the vehicle body longitudinal beam 2 due to the drag force.

[0051] It should be noted that, in addition to connecting the bottom wall and the side walls to the vehicle body longitudinal beam 2 through connecting parts, the bottom wall and the vehicle body longitudinal beam 2 can also be connected through connecting parts, and the side walls and the vehicle body longitudinal beam 2 can be welded together, or the side walls and the vehicle body longitudinal beam 2 can be connected through connecting parts, and the bottom wall and the vehicle body longitudinal beam 2 can be welded together.

[0052] Continue to refer to Figures 4 to 6 As shown in , the main body 101 of this embodiment has a cavity with a top opening, and reinforcing ribs connected between the side walls of the cavity. In addition, the reinforcing ribs include longitudinal ribs 1011 and transverse ribs 1012 interlaced in a vertical and horizontal direction, wherein the longitudinal ribs 1011 extend along the length direction of the vehicle body longitudinal beam 2, and the transverse ribs 1012 extend along the width direction of the vehicle body longitudinal beam 2. In this embodiment, by providing the longitudinal ribs 1011 and transverse ribs 1012 interlaced in a vertical and horizontal direction, not only the structural strength of the mounting member 1 can be improved, but also the dragging force of the towing device can be dispersed to the entire mounting member 1 through the reinforcing ribs, so that the mounting member 1 is subjected to a more uniform force and the stress concentration is reduced.

[0053] As a specific embodiment, the longitudinal ribs 1011 of this embodiment are specifically arranged at intervals, and the transverse ribs 1012 are arranged at intervals, six. Of course, in specific implementation, the number of longitudinal ribs 1011 and transverse ribs 1012 can be adaptively adjusted. In addition, in addition to the transverse ribs 1012 and the longitudinal ribs 1011, the reinforcing ribs can further include oblique ribs arranged at an acute angle to the transverse ribs 1012 or the longitudinal ribs 1011.

[0054] As a further embodiment, in combination Figures 4 to 6 As shown in the figure, the mounting portion 102 is a threaded mounting rod provided on the main body portion 101, and the hollow portion is specifically a through hole provided on the longitudinal beam 2 of the vehicle body. The towing device can be installed on the vehicle body by being screwed to the mounting rod. In addition, in order to further improve the firmness of the towing device, in this embodiment, a plurality of mounting rods are arranged at intervals, for example, Figure 5 As shown in , two are spaced apart along the length direction of the mounting member 1. Of course, during specific implementation, the number and arrangement positions of the mounting rods can be adjusted accordingly according to specific circumstances.

[0055] As a further embodiment, a reinforcing tube 1013 is provided in the cavity corresponding to the mounting portion 102. The reinforcing tube 1013 extends in the vertical direction of the vehicle and is connected to the longitudinal ribs 1011 and / or the transverse ribs 1012. Such a configuration can not only further improve the structural strength of the mounting member 1, but also facilitate the towing force of the towing device to be quickly transmitted to other positions of the mounting member 1 through the reinforcing ribs, further improve the force uniformity of the mounting member 1, and prevent stress concentration. Figures 4 to 6 As shown in the figure, each mounting portion 102, i.e., the mounting rod, of this embodiment is disposed at the middle of the transverse rib 1012 and connected to the transverse rib 1012. Of course, in addition to connecting the reinforcing tube 1013 to the transverse rib 1012, the reinforcing tube 1013 may also be disposed at the intersection of the transverse rib 1012 and the longitudinal rib 1011 and connected to both the transverse rib 1012 and the longitudinal rib 1011.

[0056] In addition, in order to obtain a better use effect, the mounting member 1 further includes a connecting portion 103 disposed at the end of the main body portion 101, and the connecting portion 103 is located outside the vehicle body longitudinal beam 2, and the connecting portion 103 extends radially outward from the main body portion 101, and is used to connect to the rear panel. Figure 1 and Figure 4 As shown in the figure, the connection part 103 of this embodiment is arranged along the edge of the main body part 101, and the whole is U-shaped. By arranging the connection part 103 extending radially outward at the end of the main body part 101, not only the structural strength of the mounting member 1 can be further improved, but also it is convenient to connect with the rear panel, so as to further improve the installation stability of the mounting member 1, and further improve the installation firmness of the towing device.

[0057] In addition, in order to improve the assembly efficiency and assembly accuracy of the mounting member 1, a positioning portion is provided on the mounting member 1, and the positioning portion is used to position the mounting member 1 on the vehicle body longitudinal beam 2. And, as a specific implementation, the positioning portion of this embodiment includes a plurality of positioning holes 1015 provided on the main body portion 101, and at least one of the positioning holes 1015, a tube body 1014 connected to the positioning hole 1015 is provided on the main body portion 101. Correspondingly, a through hole corresponding to the positioning hole 1015 is provided on the vehicle body longitudinal beam 2. In this embodiment, by providing the tube body 1014 connected to the positioning hole 1015, not only the structural strength at the positioning hole 1015 can be improved, but also the positioning pin can be inserted into the tube body 1014 at the same time, thereby increasing the contact area with the mounting member 1, and thus facilitating the improvement of the positioning accuracy.

[0058] Combined with Figure 5 and Figure 6As shown in , as a specific embodiment, the positioning holes 1015 of this embodiment are two arranged at intervals along the length direction of the mounting member 1, and corresponding to the positioning holes 1015 at the front, a tube body 1014 is arranged in the cavity of the main body part 101. As a further embodiment, the tube body 1014 is connected to the transverse ribs 1012, and the tube body 1014 is specifically arranged in the middle of the transverse ribs 1012, so as to further increase the structural strength and force transmission path of the mounting member 1. It should be noted that, in addition to connecting the tube body 1014 to the transverse ribs 1012, it can also be arranged at the intersection of the transverse ribs 1012 and the longitudinal ribs 1011, and connected to the transverse ribs 1012 and the longitudinal ribs 1011 at the same time.

[0059] The towing device installation structure of this embodiment adopts the above structure, which has a simple structure, strong applicability, and good structural strength and corrosion resistance. In addition, the mounting member 1 is a single part with good integrity, and the setting of the reinforcing ribs can evenly disperse the towing force, reduce stress concentration, and effectively ensure the installation firmness of the towing device on the vehicle body.

[0060] In addition, the present embodiment also relates to a vehicle, on which the above-mentioned towing device mounting structure is provided.
