Technical Field

[0001] This application relates to the field of chassis technology, and in particular to an installation structure and vehicle. Background Technology

[0002] Trailer towing devices are generally located at the rear of a vehicle and are mainly used to expand the vehicle's carrying capacity to meet the towing needs of RVs, luggage racks, bicycle racks, and small trucks.

[0003] Currently, trailer towing devices are generally installed on vehicles via bracket structures on both sides and a crossbeam structure in the middle. While this existing installation method can achieve the installation of trailer towing devices on vehicles, it still has shortcomings such as limited structural strength, making it difficult to meet higher towing requirements. Utility Model Content

[0004] In view of this, this application aims to provide an installation structure that enables trailer towing devices installed on vehicles to meet higher towing requirements.

[0005] To achieve the above objectives, the technical solution of this application is implemented as follows: An installation structure is suitable for installing a trailer towing device on a vehicle, and includes vehicle body connecting brackets disposed on the left and right sides, a mounting beam connecting the two vehicle body connecting brackets, and a mounting plate for mounting the trailer towing device disposed on the mounting beam. The vehicle body connecting bracket includes a vehicle body connecting plate connected to the vehicle body longitudinal beam, and a crossbeam mounting bracket connected to the vehicle body connecting plate, wherein the mounting crossbeam passes through the connecting hole on the crossbeam mounting bracket. The crossbeam mounting bracket is box-shaped, with connection holes on two opposite side walls. A first flange is formed at each edge of one end of the crossbeam mounting bracket, and a second flange is formed at each connection hole. The first flange is connected to the vehicle body connecting plate.

[0006] Furthermore, the mounting beam is a tubular beam, and the cross-section of the mounting beam is circular.

[0007] Furthermore, the mounting plates are multiple pieces arranged at intervals along the length of the mounting beam, and an installation space is formed between two adjacent mounting plates; The trailer towing device is installed within the installation space, and the trailer towing device is connected to each of the mounting plates.

[0008] Furthermore, a threaded tube for connecting trailer components is provided at at least one side of the vehicle body connecting bracket.

[0009] Furthermore, the threaded tube is located inside the crossbeam mounting bracket, and one end of the threaded tube is connected to the vehicle body connecting plate, while the other end of the threaded tube passes through the mounting crossbeam and is connected to the mounting crossbeam.

[0010] Furthermore, the body connecting plate is mated with the longitudinal beam end plate at the end of the body longitudinal beam, and the body connecting plate and the longitudinal beam end plate are fixedly connected together by a first connector.

[0011] Furthermore, a connecting bracket is connected to the side of the vehicle body connecting plate facing the vehicle body longitudinal beam, and the connecting bracket extends toward the side of the vehicle body longitudinal beam and is connected to the vehicle body longitudinal beam.

[0012] Furthermore, the connecting bracket abuts against the bottom of the vehicle body longitudinal beam, and the vehicle body longitudinal beam is provided with a connecting reinforcement structure, and the connecting bracket is connected to the connecting reinforcement structure.

[0013] Furthermore, the connection reinforcement structure includes a connecting sleeve and a reinforcing plate connected between the connecting sleeve and the inner wall of the vehicle body longitudinal beam, and the connecting bracket is connected to the connecting sleeve via a second connector.

[0014] Compared with related technologies, this application has the following advantages: (1) The installation structure described in this application makes the crossbeam mounting bracket in the vehicle body connecting bracket into a square box shape, and forms a first flange at each side edge of one end of the crossbeam mounting bracket, and forms a second flange at each connecting hole, and makes the first flange connected to the vehicle body connecting plate. Thus, by using the first flange and the second flange arranged around the perimeter, the structural strength of the crossbeam mounting bracket, which is the core connecting component in the installation structure, can be significantly increased, and the strength and durability of the entire installation structure can be improved, thereby making it easier for the trailer towing device installed on the vehicle to meet higher towing requirements.

[0015] (2) The installation beam is made of tubular beam and the cross-section of the installation beam is circular. This not only facilitates the preparation of the installation beam, but also utilizes the characteristics of the circular tubular beam, which has strong load-bearing capacity and good bending resistance, to further increase the overall strength of the installation structure and improve the towing capacity of the installed trailer traction device.

[0016] (3) The mounting plates are arranged in multiple spaced sections, so that the trailer towing device is installed in the installation space between adjacent mounting plates and the trailer towing device is connected to each mounting plate. Multiple mounting plates can be used to ensure the structural strength and stability of the installation point of the trailer towing device, and can better improve the towing capacity of the trailer towing device.

[0017] (4) Setting a threaded tube at the vehicle body connection bracket can facilitate the installation of the threaded tube on the vehicle, and can also meet the installation requirements of the trailer rescue component, which helps to improve the functionality of the installation structure.

[0018] (5) The threaded tube is located inside the crossbeam mounting bracket, which can make full use of the internal space of the crossbeam mounting bracket, increase the integration of the component layout, and make one end of the threaded tube connected to the vehicle body connecting plate, and the other end pass through the mounting crossbeam and is also connected to the mounting crossbeam. This can also ensure the reliability of the threaded tube connection and prevent the threaded tube from falling off during rescue.

[0019] (6) The body connecting plate is connected to the longitudinal beam end plate at the end of the body longitudinal beam, and the two are fixed together by the first connector. This facilitates the connection between the installation structure and the body longitudinal beam, and also helps to ensure the reliability of the connection between the installation structure and the body longitudinal beam.

[0020] (7) By setting a connecting bracket on one side of the vehicle body connecting plate and connecting the connecting bracket to the vehicle body longitudinal beam, the stability of the installation structure on the vehicle can be better increased by utilizing the further connection between the connecting bracket and the vehicle body longitudinal beam, which helps to improve the towing requirements of the trailer towing device after installation.

[0021] (8) Connecting the connecting bracket to the bottom of the vehicle body longitudinal beam facilitates the connection operation, reduces interference and influence caused by the vehicle body components around the vehicle body longitudinal beam, and sets up a connecting reinforcement structure in the vehicle body longitudinal beam, and connects the connecting bracket to the connecting reinforcement structure, which can ensure the connection strength between the connecting bracket and the vehicle body longitudinal beam and improve the setting effect of the connecting bracket.

[0022] (9) The connecting reinforcement structure adopts a connecting sleeve and a reinforcing plate connected between the connecting sleeve and the longitudinal beam of the vehicle body, which can facilitate the connection between the connecting bracket and the connecting reinforcement structure, increase the convenience of the connection operation, and at the same time ensure the stability of the connecting sleeve in the longitudinal beam of the vehicle body, and improve the stability of the connection between the connecting bracket and the longitudinal beam of the vehicle body.

[0023] Another object of this application is to provide a vehicle equipped with a trailer towing device, which is mounted on the vehicle by means of the mounting structure described above.

[0024] By setting the above-mentioned installation structure, the vehicle described in this application is able to meet higher towing requirements for the trailer towing device installed on the vehicle, thereby improving the quality of use of the vehicle equipped with the trailer towing device.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0031] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0032] An embodiment of the first aspect of this application provides an installation structure suitable for mounting a trailer towing device 4 on a vehicle, and the installation structure is designed to enable the trailer towing device 4 mounted on the vehicle to meet higher towing requirements, thereby helping to improve the quality of use of the vehicle equipped with the trailer towing device 4.

[0033] In related technologies, trailer towing devices 4 are generally installed at the rear of the vehicle. They are mainly of mechanical, semi-automatic and fully automatic types. The trailer towing device 4 is mainly used to expand the vehicle's carrying capacity to meet the towing needs of RVs, luggage racks, bicycle racks and small trucks.

[0034] At present, the trailer towing device 4 is generally installed on the vehicle through the bracket structure on both sides and the crossbeam structure in the middle. The bracket structure on both sides is connected to the longitudinal beam of the vehicle body to realize the installation structure of the trailer towing device 4 in the vehicle body. The crossbeam structure is provided with mounting points to realize the installation of the trailer towing device 4.

[0035] The existing installation methods described above can enable the trailer towing device 4 to be installed on the vehicle. However, since the bracket structure used is usually a simple "L" or "U" shaped stamped plate structure, it still has shortcomings such as limited structural strength, making it difficult for the installed trailer towing device 4 to meet higher towing requirements.

[0036] In view of this, in order to overcome the shortcomings of related technologies, the installation structure of this embodiment combines... Figures 1 to 8 As shown, the overall design includes vehicle body connecting brackets 1 located on the left and right sides, a mounting beam 2 connecting the two vehicle body connecting brackets 1, and a mounting plate 3 on the mounting beam 2 for mounting a trailer towing device 4.

[0037] Each of the body connecting brackets 1 on each side includes a body connecting plate 101 connected to the body longitudinal beam 6, and a crossbeam mounting bracket 102 connected to the body connecting plate 101. Each end of the mounting crossbeam 2 passes through the connecting hole 1021 on the crossbeam mounting bracket 102 on the same side.

[0038] Meanwhile, the crossbeam mounting bracket 102 is box-shaped, and connection holes 1021 are provided on the two opposite side walls of the crossbeam mounting bracket 102. A first flange 102a is formed at each side edge of one end of the crossbeam mounting bracket 102, and a second flange 102b is formed at each connection hole 1021. The first flange 102a is also connected to the vehicle body connecting plate 101.

[0039] Therefore, based on the body connecting bracket 1 including the body connecting plate 101 and the crossbeam mounting bracket 102, by making the crossbeam mounting bracket 102 in the body connecting bracket 1 into a square box shape, and forming a first flange 102a at each side edge of one end of the crossbeam mounting bracket 102, and forming a second flange 102b at each connecting hole 1021, and making the first flange 102a at one end of the crossbeam mounting bracket 102 connected to the body connecting plate 101, this embodiment can significantly increase the structural strength of the crossbeam mounting bracket 102, which is the core connecting component in the installation structure, by utilizing the first flange 102a and the second flange 102b arranged around the perimeter, thereby improving the strength and durability of the entire installation structure, so as to increase the towing requirements of the trailer towing device 4 installed on the vehicle by utilizing the increase in the strength of the installation structure itself.

[0040] Based on the above overview, specifically, it remains as follows: Figures 1 to 4 As shown in the figure, as a preferred exemplary embodiment, in the body connecting bracket 1 of this embodiment, the body connecting plate 101 can be a flat plate structure formed by stamping, and the crossbeam mounting bracket 102 can also be prepared by stamping, and then welded to make it into a square box structure after stamping.

[0041] It is worth noting that the square box-shaped crossbeam mounting bracket 102 in this embodiment has open ends. One end of the open ends of the crossbeam mounting bracket 102 has a first flange 102a formed and connected to the vehicle body connecting plate 101, while the other end has a connecting hole 1021 for connecting and installing the crossbeam 2.

[0042] In addition, in the specific manufacturing process, the connecting hole 1021 is usually punched out first, then the second flange 102b is punched out at the connecting hole 1021, and then the crossbeam mounting bracket 102 is bent into a square box shape by stamping. Then the first flange 102a is punched out at one end, and then the crossbeam mounting bracket 102 is welded into an integral structure.

[0043] In this embodiment, also as a preferred implementation, after the mounting beam 2 passes through the two oppositely arranged connecting holes 1021 on the beam mounting bracket 102, welding can usually be performed at the second flange 102b position of each connecting hole 1021, that is, the second flange 102b is welded and fixed together with the mounting beam 2. In this way, it not only facilitates the welding connection between the mounting beam 2 and the beam mounting bracket 102, but also helps to ensure the reliability of the connection between them.

[0044] Continue to combine Figures 1 to 3 As shown in this embodiment, in some exemplary implementations, the mounting beam 2 may be a pipe beam, and based on the use of a pipe beam, the cross section of the mounting beam 2 may be designed to be circular, so that the mounting beam 2 is specifically a circular pipe beam.

[0045] It is understandable that by making the mounting beam 2 a tubular beam with a circular cross-section, it is not only easier to prepare the mounting beam 2, but also to take advantage of the strong load-bearing capacity and good bending resistance of the circular tubular beam, thereby further increasing the overall strength of the installation structure and improving the towing capacity of the trailer traction device 4 after installation.

[0046] In this embodiment, in some exemplary implementations, preferably, the mounting plate 3 can be a plurality of pieces arranged at intervals along the length of the mounting beam 2, and based on the fact that the mounting plate 3 is a plurality of pieces arranged at intervals, an installation space Q is formed between two adjacent mounting plates 3, and the trailer towing device 4 is installed in the installation space Q, and the trailer towing device 4 is also connected to each mounting plate 3.

[0047] In practice, it will still be as follows Figures 1 to 3 As shown, the spaced mounting plates 3 can be, for example, two pieces. The two mounting plates 3 can be fixed to the mounting beam 2 by welding, and the trailer towing device 4 can generally be installed in the mounting space Q between the two mounting plates 3 by bolt pairs. The bolts in the bolt pairs pass through the two mounting plates 3, thereby realizing the connection between the trailer towing device 4 and each mounting plate 3.

[0048] It is worth noting that, apart from having two mounting plates 3 as shown in the figure, when there are other numbers of mounting plates 3, the position of the mounting space Q can be determined according to the arrangement requirements of the trailer towing device 4, etc. Moreover, as a preferred embodiment, the number of mounting plates 3 should generally be even, and the number of mounting plates 3 on both sides of the mounting space Q should be the same.

[0049] It is understandable that by setting the mounting plates 3 for installing the trailer towing device 4 as multiple pieces arranged at intervals, the trailer towing device 4 is installed in the installation space Q between adjacent mounting plates 3, and the trailer towing device 4 is connected to each mounting plate 3. This can utilize multiple mounting plates 3 to ensure the structural strength and installation stability of the mounting point of the trailer towing device 4, thereby better improving the towing capacity of the trailer towing device 4.

[0050] In this embodiment, in some exemplary implementations, see also... Figures 1 to 5 As shown, a threaded pipe 5 for connecting trailer components can be provided, for example, at the vehicle body connecting bracket 1 on one side.

[0051] The aforementioned trailer component can be, for example, a trailer hook that can be screwed into the threaded tube 5, or other components with similar functions. When a vehicle needs rescue, the trailer hook or similar component is first screwed into the threaded tube 5, and then the trailer component is connected to the rescue vehicle, allowing the rescued vehicle to be towed to get out of trouble.

[0052] In practical implementation, the aforementioned threaded pipe 5 can be any product that meets the relevant design and usage requirements. Moreover, by setting the threaded pipe 5 at the vehicle body connecting bracket 1, it is obvious that it is easier to install the threaded pipe 5 on the vehicle, and it is also beneficial to meet the installation requirements of trailer rescue components, thus helping to improve the functionality of the installation structure.

[0053] In addition, the specific arrangement of the threaded pipe 5 still refers to... Figure 4 and Figure 5As shown, in some exemplary embodiments, the threaded tube 5 may be located, for example, within the crossbeam mounting bracket 102, and one end of the threaded tube 5 is connected to the vehicle body connecting plate 101, while the other end of the threaded tube 5 passes through the mounting crossbeam 2 and is connected to the mounting crossbeam 2.

[0054] At this time, the threaded tube 5 is located inside the crossbeam mounting bracket 102, which can make full use of the internal space of the crossbeam mounting bracket 102 to increase the integration of the component layout. Furthermore, by connecting one end of the threaded tube 5 to the vehicle body connecting plate 101 and the other end passing through the mounting crossbeam 2 and being connected to the mounting crossbeam 2, the reliability of the connection of the threaded tube 5 can be guaranteed, preventing the threaded tube 5 from falling off during rescue and ensuring the smooth progress of vehicle rescue work.

[0055] It should be noted that the threaded pipe 5 and the vehicle body connecting plate 101, as well as the threaded pipe 5 and the mounting beam 2, are generally connected by welding. Meanwhile, to ensure the threaded connection length between the trailer components and the threaded pipe 5, in specific implementation, such as... Figure 5 As shown, one end of the threaded pipe 5 that connects to the body connecting plate 101 may be exposed, for example.

[0056] In addition, besides setting a threaded tube 5 at one of the body connecting brackets 1 on one side, it is also possible to set threaded tubes 5 at both of the body connecting brackets 1 on both sides, depending on the specific design requirements. There is no restriction on this.

[0057] In this embodiment, in some exemplary implementations, the following continues... Figures 6 to 8 As shown, the body connecting plate 101 in each side body connecting bracket 1 can, for example, be connected to the longitudinal beam end plate 601 at the end of the longitudinal beam 6 on the same side, and the body connecting plate 101 and the corresponding longitudinal beam end plate 601 are also fixed together by the first connecting member 7.

[0058] The aforementioned longitudinal beam end plate 601, as part of the vehicle body longitudinal beam 1, is generally installed at the end of the vehicle body longitudinal beam 6 by welding. The aforementioned first connecting member 7 can generally be a bolt, so as to realize the connection between the vehicle body connecting plate 101 and the longitudinal beam end plate 601 using conventional bolting methods. In specific implementation, for example, the first connecting member 7 can be provided at each corner of the vehicle body connecting plate 101 to ensure the stability of the connection between the vehicle body connecting plate 101 and the vehicle body longitudinal beam 6.

[0059] It is understandable that by connecting the vehicle body connecting plate 101 to the longitudinal beam end plate 601 at the end of the vehicle body longitudinal beam 6 and fixing the two together through the first connector 7, it is convenient to realize the connection between the installation structure and the vehicle body longitudinal beam 6 in this embodiment. At the same time, it is also helpful to ensure the reliability of the connection between the installation structure and the vehicle body longitudinal beam 6, which helps to improve the stability of the trailer towing device 4 installed on the vehicle.

[0060] In this embodiment, based on the connection between the vehicle body connecting plate 101 and the longitudinal beam end plate 601 at the end of the vehicle body longitudinal beam 6, further, in some exemplary embodiments, a connecting bracket 103 may be provided on the side of the vehicle body connecting plate 101 facing the vehicle body longitudinal beam 6. The connecting bracket 103 extends toward the side of the vehicle body longitudinal beam 6 and is also connected to the vehicle body longitudinal beam 6.

[0061] At this time, by setting a connecting bracket 103 on one side of the vehicle body connecting plate 101 and connecting the connecting bracket 103 to the vehicle body longitudinal beam 6, it is clear that the further connection between the connecting bracket 103 and the vehicle body longitudinal beam 6 can better increase the stability of the installation structure on the vehicle, which helps to improve the towing requirements of the trailer towing device 4 after installation.

[0062] In specific implementation, as an example, the aforementioned connecting bracket 103 may be made of forging, and the connecting bracket 103 as a whole may be "L" shaped and connected to the vehicle body connecting plate 101 through the third connecting piece 9.

[0063] The aforementioned third connector 9 can also be bolted to secure the connecting bracket 103 to the vehicle body connecting plate 101 via bolting. Alternatively, besides using forgings, other structures that meet the corresponding usage requirements can also be used for the connecting bracket 103.

[0064] Still Figures 6 to 8 As shown, based on the above-mentioned connection bracket 103, in some exemplary embodiments of this embodiment, the connection bracket 103 may abut against the bottom of the vehicle body longitudinal beam 6, and a connection reinforcement structure 8 is also provided in the vehicle body longitudinal beam 6, and the connection bracket 103 is connected to the connection reinforcement structure 8.

[0065] In this way, by connecting the connecting bracket 103 to the bottom of the vehicle longitudinal beam 6, compared with the side connection method, it is obviously easier to carry out the connection operation, which can reduce the interference and influence caused by the vehicle body components around the vehicle longitudinal beam 6. At the same time, by setting the connecting reinforcement structure 8 in the vehicle longitudinal beam 6 and connecting the connecting bracket 103 to the connecting reinforcement structure 8, it is obvious that the connection strength between the connecting bracket 103 and the vehicle longitudinal beam 6 can be guaranteed, and the setting effect of the connecting bracket 103 can be improved.

[0066] In specific implementations, in some exemplary embodiments, the aforementioned connection reinforcement structure 8 may include, for example, a connection sleeve 801 and a reinforcing plate 802 connected between the connection sleeve 801 and the inner wall of the vehicle body longitudinal beam 6, and the connection bracket 103 is connected to the connection sleeve 801 via the second connector 10.

[0067] The connecting sleeve 801 can be made using an existing structure with threaded holes, the second connecting piece 10 can be made using bolts, and the reinforcing plate 802 can be made using a stamped sheet metal part.

[0068] In terms of design, the aforementioned reinforcing plate 802 can be connected to both sides of the inner side wall and bottom wall of the vehicle body longitudinal beam 6. At the same time, the reinforcing plate 802 is also connected to the outer peripheral wall of one side of the connecting sleeve 801. The reinforcing plate 802 and the connecting sleeve 801, as well as the reinforcing plate 802 and the inner wall of the vehicle body longitudinal beam 6, are usually connected by welding.

[0069] Understandably, the use of a connecting sleeve 801 and a reinforcing plate 802 connecting the connecting sleeve 801 and the longitudinal beam 6 within the vehicle body longitudinal beam 6, achieved through bolts, facilitates the connection between the connecting bracket 103 and the reinforcing structure 8, increasing the ease of connection operation. Simultaneously, the reinforcing plate 802 ensures the stability of the connecting sleeve 801 within the longitudinal beam 6, thereby enhancing the robustness of the connection between the connecting bracket 103 and the longitudinal beam 6.

[0070] Furthermore, in specific implementation, based on the above-mentioned connection reinforcement structure 8, which adopts the connecting sleeve 801 and the reinforcing plate 802, as a preferred implementation, for example, the connecting sleeve 801 and the reinforcing plate 802 can be arranged in two sets at intervals, and the connecting bracket 103 can also be connected to each connecting sleeve 801 through two second connecting pieces 10 respectively.

[0071] By setting the connecting sleeve 801 and the reinforcing plate 802 in the connecting reinforcement structure 8 as two sets, the stability of the connection between the connecting bracket 103 and the vehicle body longitudinal beam 6 can be further improved, thereby better ensuring the reliability of the installation structure of this embodiment on the vehicle.

[0072] It is worth noting that, regarding the installation structure of this embodiment, based on the above exemplary implementations, in specific implementation, as a preferred embodiment, it is still based on... Figures 1 to 8 As shown, it may include, for example, vehicle body connecting brackets 1 disposed on the left and right sides, mounting beams 2 connected between the two vehicle body connecting brackets 1, and mounting plate 3 disposed on the mounting beams 2 for mounting trailer towing devices 4.

[0073] Each of the body connecting brackets 1 includes a body connecting plate 101 connected to the body longitudinal beam 6, and a crossbeam mounting bracket 102 connected to the body connecting plate 101. The crossbeam mounting bracket 102 is box-shaped and has connection holes 1021 on two opposite side walls. The end of the mounting crossbeam 2 passes through the connection holes 1021 on the crossbeam mounting bracket 102. A first flange 102a is formed at each side edge of one end of the crossbeam mounting bracket 102, and a second flange 102b is formed at each connection hole 1021. The first flange 102a is welded to the body connecting plate 101, and the second flange 102b is welded to the mounting crossbeam 2.

[0074] The mounting beam 2 is a circular tubular beam. A threaded pipe 5 for connecting trailer components is installed on one side of the vehicle body connecting bracket 1. The threaded pipe 5 is located inside the beam mounting bracket 102 and is connected to the vehicle body connecting plate 101 and the mounting beam 2. Simultaneously, a connecting bracket 103 is provided on the side of the vehicle body connecting bracket 101 opposite to the beam mounting bracket 102. The connecting bracket 103 is also connected to the connecting reinforcement structure 8 inside the vehicle body longitudinal beam 6.

[0075] In the preferred embodiment of the above installation structure, the specific settings and arrangements of the vehicle body connecting bracket 1, the mounting beam 2, and the connecting reinforcement structure 8 can still be referred to the descriptions in the above exemplary embodiments. Furthermore, in this preferred embodiment, the beneficial effects brought about by the design of the vehicle body connecting bracket 1, the mounting beam 2, and the connecting reinforcement structure 8 can also be referred to the descriptions in the above exemplary embodiments.

[0076] Furthermore, it is worth noting that the trailer towing device 4 in this embodiment can be an existing mechanical, semi-automatic, or fully automatic product, as long as it can be mounted on the mounting beam 2 via the mounting plate 3.

[0077] Furthermore, it is worth noting that, based on the above-mentioned vehicle body connecting bracket 1, and especially the crossbeam mounting bracket 102 with the first flange 102a and the second flange 102b formed, the installation structure of this embodiment, particularly the position of the crossbeam mounting bracket 102 in the vehicle body connecting bracket 1, was subjected to damage analysis using the structural mechanics simulation software ABAQUS. The analysis results showed that the damage value was around 0.3, which meets the requirement of a target value < 1.

[0078] The mounting structure of this embodiment adopts the above design, which can significantly increase the structural strength of the crossbeam mounting bracket 102, which is the core connecting component in the mounting structure, and also increase the connection strength between the mounting structure and the vehicle longitudinal beam 6. Thus, this embodiment can improve the strength and durability of the entire mounting structure, which can help the trailer towing device 4 installed on the vehicle meet higher towing requirements and has good practicality.

[0079] A second aspect of this application provides a vehicle equipped with a trailer towing device 4, the trailer towing device 4 being mounted on the vehicle via the mounting structure described in the first aspect embodiment above. In the vehicle of this embodiment, the above-mentioned mounting structure is generally set at the rear of the vehicle to install the trailer towing device 4 at the rear end of the vehicle body. At this time, the above-mentioned vehicle body longitudinal beam 6 is usually the rear floor longitudinal beam in the vehicle body. When the above-mentioned mounting structure is provided, it should be noted that the rear anti-collision beam is no longer connected at the rear end of the vehicle body longitudinal beam 6.

[0080] However, it is understandable that although the rear anti-collision beam is no longer connected, the above-mentioned installation structure after connection can still act as an anti-collision beam to a certain extent by utilizing the body connecting brackets 1 at both ends, especially the mounting beam 2 connected between the two body connecting brackets 1, in order to help ensure the collision safety of the rear of the vehicle.

[0081] The vehicle in this embodiment, by setting the above-mentioned installation structure, is able to enable the trailer towing device 4 installed on the vehicle to meet higher towing requirements, thereby improving the quality of use of the vehicle equipped with the trailer towing device 4 and having good practicality.
