Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of anti-collision beams, in particular to a rear anti-collision beam assembly and a vehicle. BACKGROUND

[0002] With the improvement of people's living standards, cars have gradually become a necessary means of transportation for most families. Among them, the rear collision beam is generally provided on the car body, which is generally installed below the trunk, and can absorb and disperse the force generated during the collision process when the vehicle is hit, thereby playing a role in protecting the rear of the vehicle and the safety of passengers.

[0003] With the gradual improvement of users' demand for cars, users have higher requirements for the diversified functions of cars, but the existing rear anti-collision beam only has the function of energy absorption and anti-collision, and cannot meet the diversified needs of users for the function of the anti-collision beam. SUMMARY

[0004] The purpose of the present application is to provide a rear anti-collision beam assembly and a vehicle to solve the problem that the existing rear anti-collision beam only has the function of energy absorption and anti-collision, and cannot meet the diversified needs of users for the function of the anti-collision beam.

[0005] In order to achieve the above-mentioned purpose, the technical scheme adopted by the present application is as follows:

[0006] In a first aspect, the present application provides a rear anti-collision beam assembly for installation on a vehicle. The rear anti-collision beam assembly includes two anti-collision beam bodies and a connecting assembly. The anti-collision beam body includes a support beam and a mounting seat. The support beam is rotatably connected to the mounting seat. The mounting seat is used to be installed on the vehicle. The connecting assembly is used to be detachably connected with the two support beams. The two anti-collision beam bodies are connected to each other through the connecting assembly.

[0007] According to the above technical means, the rear anti-collision beam assembly provided by the present application can connect the two support beams together to form a complete anti-collision beam structure when the rear anti-collision beam assembly needs to play the role of anti-collision and energy absorption. At this time, the rear anti-collision beam assembly can play the role of anti-collision and energy absorption. When the user needs to place luggage and other items, the connecting assembly can be detached from the two support beams. At this time, since the support beam is rotatably connected to the mounting seat, the two support beams can be rotated relative to the mounting seat, so that the two support beams can be rotated relative to the vehicle body. In this way, the two support beams can form a lap joint space, and the luggage compartment can be placed on the two support beams. At this time, the rear anti-collision beam assembly can play the role of placing luggage.

[0008] In a possible implementation, the mounting base comprises a mounting member and an energy-absorbing assembly. The mounting member is configured to be mounted on a vehicle. The energy-absorbing assembly is connected to the mounting member. The energy-absorbing assembly is configured to absorb energy when deformed. The support beam is rotatably connected to the energy-absorbing assembly.

[0009] According to the above technical means, the mounting base can be mounted on the vehicle through the mounting member, and the mounting base can be mounted. Since the mounting base further comprises the energy-absorbing assembly, when the vehicle is subjected to external impact, the energy-absorbing assembly can absorb energy, so that the rear crash beam assembly can better absorb energy, and the energy-absorbing performance of the rear crash beam assembly can be improved.

[0010] In a possible implementation, the support beam comprises a beam body and a connecting column. The connecting column is connected to one end of the beam body. The energy-absorbing assembly comprises a connecting sleeve. The connecting sleeve forms a mounting cavity with an opening. The connecting column is located in the mounting cavity and is rotatably connected to the connecting sleeve.

[0011] According to the above technical means, since the connecting column is arranged in the connecting sleeve, the connecting column can rotate in the connecting sleeve, thereby driving the beam body connected to the connecting column to rotate. When it is necessary to place luggage, the two beam bodies can be placed in a position by rotating the beam bodies, and the luggage can be arranged on the two beam bodies.

[0012] In a possible implementation, a plurality of first connecting holes are formed in the circumferential wall of the connecting column and are arranged at intervals in the circumferential direction. A second connecting hole is formed in the circumferential wall of the connecting sleeve. The rear crash beam assembly further comprises a first fastener. The first fastener is arranged in the first connecting hole and the second connecting hole to prevent the connecting column and the connecting sleeve from rotating relative to each other.

[0013] According to the above technical means, when the first fastener is arranged in the first connecting hole and the second connecting hole, the connecting sleeve and the connecting column can be fixed relative to each other and cannot continue to rotate. In this way, when the beam body is used to place luggage, the problem that the luggage falls off due to the rotation of the connecting column driving the rotation of the beam body can be avoided. Since a plurality of first connecting holes are formed in the circumferential wall of the connecting column and are arranged at intervals in the circumferential direction. In this way, when the beam body needs to realize different functions, the first connecting holes at different positions on the connecting column can be arranged opposite to the second connecting hole by rotating the beam body, so that the first fastener can be used for subsequent fixation.

[0014] In a possible implementation, the support beam further comprises a fixing member. The fixing member is connected to the beam body and located on one side of the beam body. A sliding groove is formed in the surface of the fixing member away from the beam body.

[0015] According to the above technical means, when the beam body is used for placing the luggage, the fixing member can be located above the beam body. In this way, the sliding groove on the fixing member can be used to clamp a part of the luggage in the sliding groove, so as to facilitate the position positioning and fixing of the luggage.

[0016] In a possible implementation, the energy absorption assembly further comprises at least one energy absorption member. The energy absorption member is hollow inside and has openings at both ends. The energy absorption member is arranged between the connecting sleeve and the mounting member. The connecting sleeve and the mounting member are located on the side of the opening at one end of the energy absorption member.

[0017] According to the above technical means, when the vehicle collides, the energy absorption member can deform to absorb energy after being impacted due to the hollow inside of the energy absorption member, thereby reducing the impact force on the vehicle body and providing good protection for the vehicle body. It can be understood that when the energy absorption member is arranged on the vehicle body, the openings at both ends of the energy absorption member can be arranged at intervals along the length direction of the vehicle body. In this way, the side of the opening at one end of the energy absorption member is impacted first, which can better make the energy absorption member deform and provide better energy absorption effect.

[0018] In a possible implementation, the energy absorption assembly further comprises a mounting plate. The at least one energy absorption member and the connecting sleeve are detachably connected with the mounting plate. The mounting plate is further connected with the mounting member.

[0019] According to the above technical means, the mounting plate can provide mounting positions for the energy absorption member and the connecting sleeve. At the same time, since the mounting plate is connected with the mounting member, the energy absorption member and the connecting sleeve can be mounted on the mounting member through the mounting member.

[0020] In a possible implementation, the end of the beam body away from the connecting column is provided with a third connecting hole. The connecting assembly comprises a connecting member and a second fastener. The connecting member is provided with a plurality of fourth connecting holes. The second fastener is arranged in the third connecting hole and the fourth connecting hole. The connecting member is connected with the beam body through the second fastener.

[0021] According to the above technical means, by arranging the second fastener in the third connecting hole and the fourth connecting hole, the connection between the connecting assembly and the beam body can be realized.

[0022] In a possible implementation, the number of third connecting holes is a plurality. The plurality of third connecting holes are arranged at intervals along the extension direction of the beam body.

[0023] According to the above technical means, when the two beam bodies do not need to be connected with each other by the connecting assembly, the connection position of the connecting member on the beam body can be changed, so that the connecting member can be hidden below the beam body, facilitating the placement of the connecting member.

[0024] In one possible implementation, the connector includes a first connector, a second connector, and a third fastener. The first connector has a fifth connecting hole. The second connector has a sixth connecting hole. The third fastener passes through both the fifth and sixth connecting holes. The first connector is connected to the second connector via the third fastener. Both the first and second connectors have a fourth connecting hole.

[0025] According to the aforementioned technical means, the connection between the first connector and the second connector can be achieved through the cooperation between the third fastener and the fifth and sixth connecting holes. Furthermore, by providing the first and second connectors, when connecting the two beam bodies, the first and second connectors can be pre-installed on the two beam bodies respectively, and then the connection between the first and second connectors can be completed, making the connection more convenient.

[0026] In one possible implementation, a recess is formed on one side of the first connector. A protrusion is formed on one side of the second connector. The protrusion is located within the recess.

[0027] According to the above-mentioned technical means, when installing the first connector and the second connector, the protrusion and the recess can be used for positioning to facilitate subsequent installation.

[0028] Secondly, embodiments of this application provide a vehicle including any of the rear bumper beam assemblies described in the first aspect.

[0029] Since the vehicle provided in this application includes any of the rear bumper beam assemblies in the first aspect, it can solve the same technical problems as the rear bumper beam assemblies described above and achieve the same technical effects, it will not be described again here.

DETAILED DESCRIPTION

[0035] In order for those skilled in the art to better understand the technical solutions of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0036] It should be noted that the terms "first", "second" and the like in the specification and claims of the present application and the above-described accompanying drawings are used to distinguish similar objects, and do not necessarily have to describe a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all the embodiments consistent with the present application. Rather, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0037] The rear anti-collision beam of the automobile is generally arranged at the tail of the vehicle body, below the position of the trunk door. When the tail of the vehicle collides, the rear anti-collision beam of the automobile can absorb and disperse the impact force generated during the collision, so that the tail of the vehicle body is not easily deformed, thereby protecting the passengers.

[0038] With the increasing demand of users for automobiles, the demand for diversification of automobiles is increasing. For example, users gradually increase the demand for automobile space to meet the demand of users for large passenger space and high storage capacity of automobiles. In particular, there is a further demand for the use of space outside the automobile, and it is hoped that the space outside the vehicle body can be used more efficiently.

[0039] In the related art, the rear anti-collision beam of the automobile can generally only absorb energy and reduce the impact of the collision, and cannot meet the demand of the user for the multifunctional rear anti-collision beam. Based on this, the present application provides a vehicle. In the present application, the specific type of the vehicle is not limited, for example, the vehicle provided in the present application can be an electric vehicle, a hybrid vehicle or a solar vehicle.

[0040] To realize the basic functions of the automobile, the vehicle can include components such as a vehicle body, a chassis, a power system, and an electrical system.

[0041] The vehicle body can include a vehicle frame, vehicle doors, and vehicle windows. The vehicle frame can form the overall shape configuration of the exterior of the vehicle and form a passenger space for accommodating passengers. The vehicle doors can be rotatably connected to the vehicle frame and can open or close the interior driving space. The vehicle windows can be installed on the vehicle doors or the vehicle frame to facilitate passengers to observe the external environment.

[0042] The chassis can include components such as a drive system and a transmission system. The drive system can drive the wheels to rotate. According to different driving modes of the drive system, the drive system can be divided into front drive, rear drive, and four-wheel drive arrangements. The transmission system can transmit the power generated by the engine to the wheels.

[0043] The power system can provide power for the vehicle, so that the vehicle can complete the basic driving function. According to the type of the vehicle, the composition of the power system is also different. For example, when the vehicle is an electric vehicle, the power system can include an electric motor.

[0044] In addition, the vehicle provided by the embodiment of the present application can also include a rear anti-collision beam assembly, which can be used to be installed on the vehicle. For example, the rear anti-collision beam assembly can be installed at the rear of the vehicle body. The rear anti-collision beam assembly provided by the embodiment of the present application can meet the user's demand for a multifunctional rear anti-collision beam.

[0045] Next, the rear anti-collision beam assembly provided by the embodiment of the present application will be described in detail. As shown in Figure 1 The rear anti-collision beam assembly 100 can include two anti-collision beam bodies 10 and a connecting assembly 40. The anti-collision beam body 10 can include a support beam 20 and a mounting seat 30. The mounting seat 30 can be installed on the vehicle. In this way, the anti-collision beam body 10 can be installed on the vehicle through the mounting seat 30 to realize the installation and fixation on the vehicle.

[0046] The support beam 20 can be rotatably connected to the mounting seat 30. In this way, the support beam 20 can rotate relative to the mounting seat 30. The connecting assembly 40 can be used to detachably connect the two support beams 20, and the two anti-collision beam bodies 10 can be connected to each other through the connecting assembly 40.

[0047] Therefore, the rear anti-collision beam assembly 100 provided by the embodiment of the present application can play the role of anti-collision energy absorption when the rear anti-collision beam assembly 100 needs to play the role of anti-collision energy absorption, such as Figure 1As shown, the connecting assembly 40 can connect the two support beams 20 together to form a complete crash beam structure. At this time, the rear crash beam assembly 100 can play a role of crash energy absorption. When the user needs to place luggage and other items, the connecting assembly 40 can be detached from the two support beams 20. At this time, since the support beam 20 is rotationally connected to the mounting seat 30, the two support beams 20 can rotate relative to the mounting seat 30, so that the two support beams 20 can rotate relative to the vehicle body. In this way, as shown, Figure 2 As shown, the two support beams 20 can form an overlapping space, and the luggage can be placed on the two support beams 20. At this time, the rear crash beam assembly 100 can play a role of placing luggage.

[0048] As shown, Figure 1 As shown, when the rear crash beam assembly 100 needs to play a role of crash energy absorption, the end portions of the two support beams 20 can be connected to each other through the connecting assembly 40, and the two support beams 20 are arranged side by side in sequence. In this way, the two support beams 20 as a whole can form a long strip-shaped structure, which plays a good role of crash impact. It can be understood that in actual application, the two support beams 20 can be arranged in sequence along the width direction of the vehicle body. The support beam 20 extends along the width direction of the vehicle body.

[0049] As shown, Figure 2 As shown, when the rear crash beam assembly 100 needs to play a role of carrying luggage, the two support beams 20 as a whole can be arranged in parallel and spaced apart. Wherein, the support beam 20 can extend along the length direction of the vehicle body. At this time, the two support beams 20 can provide a placing position for the luggage, so that the luggage can be placed on the two support beams 20, realizing efficient use of the external space of the vehicle body, and also realizing the carrying function of the rear crash beam assembly 100.

[0050] In some embodiments, as shown, Figure 3 Figure 3 An exploded view of the rear crash beam assembly 100 provided by the embodiments of the present application is shown. The mounting seat 30 can include a mounting piece 31 and an energy absorption assembly 32. Wherein, the mounting piece 31 can be mounted on the vehicle. Thus, the mounting seat 30 can be mounted on the vehicle body through the mounting piece 31, realizing the installation of the mounting seat 30.

[0051] As shown, Figure 3 As shown, the mounting piece 31 can be a plate-shaped structure. Wherein, the mounting piece 31 can be provided with a mounting hole 311. At the same time, the vehicle body can also be provided with a mounting hole. At this time, the mounting piece 31 can be mounted on the vehicle body through the bolt, realizing the installation of the mounting piece 31 on the vehicle body.

[0052] As shown, Figure 3 ​As shown, the number of mounting holes 311 can be multiple. Through multiple mounting holes 311, the mounting piece 31 can be more firmly mounted on the vehicle body, ensuring the mounting firmness of the mounting piece 31.

[0053] It can be understood that the shape of the mounting piece 31 can be designed according to actual conditions. For example, Figure 3 As shown, the mounting piece 31 as a whole can be a U-shaped plate structure. Among them, the side of the mounting piece 31 can be formed with a notch 312. In this way, the notch 312 can be used to avoid other structures of the vehicle body, facilitating the installation of the mounting piece 31.

[0054] In addition, for example, Figure 3 As shown, the mounting piece 31 can also be formed with a reinforcing rib 313. The reinforcing rib 313 can improve the overall strength of the mounting piece 31, ensuring the use strength of the mounting piece 31. For example, the reinforcing rib 313 can be provided around the mounting hole 311. In this way, the reinforcing rib 313 can improve the strength of the position where the mounting piece 31 is connected with the vehicle body, ensuring that the two can be better installed and fixed.

[0055] Since the mounting seat 30 also includes an energy-absorbing assembly 32. When the vehicle receives external impact, the energy-absorbing assembly 32 can play an energy-absorbing role, so that the rear crash beam assembly 100 can better absorb energy, improving the energy-absorbing performance of the rear crash beam assembly 100. Among them, the support beam 20 can be rotatably connected with the energy-absorbing assembly 32. Of course, in other embodiments, the mounting seat 30 can also not include the energy-absorbing assembly 32. At this time, the support beam 20 can be directly rotatably connected with the mounting piece 31.

[0056] In order to realize the rotatable connection of the support beam 20 and the energy-absorbing assembly 32. As shown, Figure 3 In some embodiments, the support beam 20 can include a beam body 21 and a connecting column 22. The connecting column 22 is connected to one end of the beam body 21. The energy-absorbing assembly 32 can include a connecting sleeve 321. The connecting sleeve 321 can form a mounting cavity with an opening. Among them, the connecting column 22 can be located in the mounting cavity and rotatably connected with the connecting sleeve 321.

[0057] Since the connecting column 22 is arranged in the connecting sleeve 321, the connecting column 22 can rotate in the connecting sleeve 321, thereby driving the beam body 21 connected with the connecting column 22 to rotate. When it is needed to place luggage, by rotating the beam body 21, the two beam bodies 21 can form a placing position, and the luggage can be arranged on the two beam bodies 21.

[0058] For example, as shown, Figure 3As shown, the connecting sleeve 321 can be a hollow cylindrical structure, and one end of the connecting sleeve 321 is formed with an opening. Correspondingly, the connecting column 22 can also be a cylindrical structure. In this way, the rotation connection between the connecting sleeve 321 and the connecting column 22 can be better achieved through the two cylindrical structures.

[0059] Of course, the rotation connection of the support beam 20 can also be achieved in other ways. For example, in some other embodiments, the beam body 21 can be provided with a rotating shaft hole, and the energy absorption assembly 32 can include a rotating shaft. At this time, the rotating shaft can be sleeved in the rotating shaft hole. In this way, the rotation connection between the beam body 21 and the energy absorption assembly 32 can also be achieved, and the specific design can be made according to the actual situation. Here, only an example is described.

[0060] In some embodiments, as shown in Figure 3 As shown, a plurality of first connecting holes 221 can be formed on the peripheral wall of the connecting column 22 and spaced apart in the circumferential direction. At the same time, a second connecting hole 3211 can be formed on the peripheral wall of the connecting sleeve 321. The rear anti-collision beam assembly 100 further includes a first fastener (not shown in the figure). The first fastener is arranged in the first connecting hole 221 and the second connecting hole 3211 to prevent the mutual rotation of the connecting column 22 and the connecting sleeve 321.

[0061] Therefore, when the first fastener is arranged in the first connecting hole 221 and the second connecting hole 3211, the connecting sleeve 321 and the connecting column 22 can be relatively fixed and cannot continue to rotate. In this way, when the beam body 21 is used to place luggage, the problem that the luggage falls off due to the rotation of the beam body 21 caused by the rotation of the connecting column 22 can be avoided.

[0062] Since a plurality of first connecting holes 221 are formed on the peripheral wall of the connecting column 22 and spaced apart in the circumferential direction. In this way, when the beam body 21 needs to achieve different functions, the beam body 21 can be rotated to make the different first connecting holes 221 on the connecting column 22 arranged opposite to the second connecting hole 3211, so that the first fastener can be used for subsequent fixation.

[0063] For example, the number of the first connecting holes 221 can be two. The included angle between the two first connecting holes 221 and the axis of the connecting column 22 can be 90 degrees. In this way, after the beam body 21 is rotated by 90 degrees, the other first connecting hole 221 can be arranged opposite to the second connecting hole 3211, and then the first fastener can be used to fix the connecting sleeve 321 and the connecting column 22.

[0064] In some embodiments, continuing to refer to Figure 3The support beam 20 can further include a fixing member 23. The fixing member 23 is connected with the beam body 21 and located on one side of the beam body 21. The fixing member 23 is formed with a sliding groove 231 on the surface away from the beam body 21. Thus, when the beam body 21 is used to place the luggage, the fixing member 23 can be located above the beam body 21. In this way, the sliding groove 231 on the fixing member 23 can be used to make a part of the luggage clamped in the sliding groove 231, so as to conveniently realize the position fixation of the luggage. In addition, for example, when the luggage is placed on the beam body 21, the luggage can be bound on the beam body 21 by a rope or the like, so as to better realize the placement of the luggage. In addition, for example, the fixing member 23 can be installed on the beam body 21 by a bolt.

[0065] In some embodiments, as shown in Figure 3 the sliding groove 231 can penetrate the fixing member 23 along the extension direction of the sliding groove 231. In this way, when a part of the luggage is placed in the sliding groove 231, it can be directly placed from one end of the sliding groove 231, without the need to lift the luggage and place it in the sliding groove 231 from above the sliding groove 231, which is more convenient. Of course, in other embodiments, the support beam 20 can also not be provided with the fixing member 23. At this time, the luggage can be directly placed on the beam body 21.

[0066] In order to better realize the energy absorption effect of the energy absorption assembly 32, as shown in Figure 3 In some embodiments, the energy absorption assembly 32 can further include at least one energy absorption member 322. The energy absorption member 322 is hollow inside and formed with openings at both ends. The energy absorption member 322 is arranged between the connecting sleeve 321 and the mounting member 31. The connecting sleeve 321 and the mounting member 31 are respectively located on the side of the opening at one end of the energy absorption member 322.

[0067] In this way, when the vehicle collides, due to the hollow inside of the energy absorption member 322, the energy absorption member 322 can deform to absorb energy after being impacted, thereby reducing the impact force on the vehicle body and providing good protection for the vehicle body. It can be understood that when the energy absorption member 322 is arranged on the vehicle body, the openings at both ends of the energy absorption member 322 can be arranged at intervals along the length direction of the vehicle body. In this way, the side of one end of the energy absorption member 322 is impacted first, which can better make the energy absorption member 322 deform and better realize the energy absorption effect.

[0068] It can be understood that the specific number of the energy absorption member 322 can be set according to actual conditions. The number of the energy absorption member 322 can be multiple. For example, Figure 3As shown, the two energy-absorbing members 322 can be arranged in a stack in the up-down direction. In this way, the energy-absorbing effect of the energy-absorbing assembly 32 can be improved by the plurality of energy-absorbing members 322, and the energy-absorbing effect of the rear crash beam assembly 100 can be improved, thereby achieving better energy absorption. Of course, in other embodiments, the number of energy-absorbing members 322 can also be one, which can be set according to actual conditions, and is only used as an example here.

[0069] In some embodiments, as shown in FIG. 1, the energy-absorbing assembly 32 can further include a mounting plate 323. The at least one energy-absorbing member 322 and the connecting sleeve 321 are respectively detachably connected to the mounting plate 323. The mounting plate 323 is further connected to the mounting member 31. In this way, the mounting plate 323 can provide mounting positions for the energy-absorbing member 322 and the connecting sleeve 321. At the same time, since the mounting plate 323 is connected to the mounting member 31, the energy-absorbing member 322 and the connecting sleeve 321 can be mounted on the mounting member 31 through the mounting member 31. Figure 3

[0070] In some embodiments, as shown in FIG. 1, the energy-absorbing assembly 32 can further include a mounting plate 323. The at least one energy-absorbing member 322 and the connecting sleeve 321 are respectively detachably connected to the mounting plate 323. The mounting plate 323 is further connected to the mounting member 31. In this way, the mounting plate 323 can provide mounting positions for the energy-absorbing member 322 and the connecting sleeve 321. At the same time, since the mounting plate 323 is connected to the mounting member 31, the energy-absorbing member 322 and the connecting sleeve 321 can be mounted on the mounting member 31 through the mounting member 31. Figure 3 Figure 3 As shown, the mounting plate 323 can be a flat plate and arranged below the energy-absorbing member 322 and the connecting sleeve 321. At the same time, as shown in FIG. 1, the bolt 50 can pass through the beam body 21 and pass through the connecting column 22 and the connecting sleeve 321 to be connected to the mounting plate 323. In this way, the support beam 20 and the energy-absorbing assembly 32 can be connected together through the bolt 50.

[0071] In some embodiments, an end of the beam body 21 away from the connecting column 22 can be provided with a third connecting hole 211. The connecting assembly 40 includes a connecting member 41 and a second fastener (not shown in the figure). The connecting member 41 is provided with a plurality of fourth connecting holes 42. The second fastener is arranged in the third connecting hole 211 and the fourth connecting hole 42. The connecting member 41 is connected to the beam body 21 through the second fastener.

[0072] In this way, the connection between the connecting assembly 40 and the beam body 21 can be achieved by arranging the second fastener in the third connecting hole 211 and the fourth connecting hole 42. For example, the number of second fasteners is two. One second fastener is arranged in the third connecting hole 211 of one beam body 21 and one fourth connecting hole 42 of the connecting member 41, and the other second fastener is arranged in the third connecting hole 211 of the other beam body 21 and the other fourth connecting hole 42 of the connecting member 41. In this way, the two fasteners can realize the connection between the two beam bodies 21, which is convenient and easy to realize.
