Description

Technical Field

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

[0002] With the improvement of people's living standards, cars have gradually become an essential means of transportation for most families. Among them, the body of the car is generally provided with a rear collision beam, which is generally installed under the trunk. When the vehicle collides, it can absorb and disperse the force generated during the collision, thereby protecting the rear of the vehicle and the safety of passengers.

[0003] As users' demands for automobiles gradually increase, users have higher requirements for the diversified functions of automobiles, but the existing rear anti-collision beams only have energy absorption and anti-collision functions, which cannot meet users' diverse demands for anti-collision beam functions. Summary of the invention

[0004] The purpose of the present application is to provide a reducer, a drive system and a vehicle, which are used to solve the problem that the existing rear anti-collision beam only has the energy absorption and anti-collision function and cannot meet the user's diverse needs for the anti-collision beam function.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is as follows:

[0006] In a first aspect, an embodiment of 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 to the two support beams. The two anti-collision beam bodies are connected to each other through the connecting assembly.

[0007] According to the above-mentioned technical means, the rear anti-collision beam assembly provided in the embodiment of the present application, when the rear anti-collision beam assembly needs to play the role of anti-collision energy absorption, the connecting assembly can connect the two support beams together to form a complete anti-collision beam structure. At this time, the rear anti-collision beam assembly can play the role of anti-collision energy absorption. When the user needs to place luggage and other items, the connecting assembly can be removed from the two support beams. At this time, since the support beams are 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 an overlap space, and the suitcase 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 embodiment, the mounting seat includes a mounting member and an energy absorbing assembly. The mounting member is used to be mounted on a vehicle. The energy absorbing assembly is connected to the mounting member. The energy absorbing assembly is used to absorb energy when deformation occurs. The support beam is rotatably connected to the energy absorbing assembly.

[0009] According to the above technical means, the mounting seat can be installed on the vehicle body through the mounting piece to achieve the installation of the mounting seat. Since the mounting seat also includes an energy absorbing component, when the vehicle receives an external impact, the energy absorbing component can play an energy absorbing role, so that the rear anti-collision beam component can better absorb energy, thereby improving the energy absorption and anti-collision performance of the rear anti-collision beam component.

[0010] In a possible implementation, the support beam includes a beam body and a connecting column. The connecting column is connected to one end of the beam body. The energy absorbing assembly includes a connecting sleeve. The connecting sleeve forms an installation cavity with an opening. The connecting column is located in the installation 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 luggage needs to be placed, the two beam bodies can form a placement position by rotating the beam body, and the luggage can be placed on the two beam bodies.

[0012] In a possible embodiment, a plurality of first connection holes spaced apart along the circumferential direction are provided on the peripheral wall of the connection column. A second connection hole is provided on the peripheral wall of the connection sleeve. The rear anti-collision beam assembly further includes a first fastener. The first fastener is inserted into the first connection hole and the second connection hole to prevent the connection column and the connection sleeve from rotating relative to each other.

[0013] According to the above technical means, when the first fastener is inserted into the first connection hole and the second connection hole, the connection sleeve and the connection column can be relatively fixed and cannot continue to rotate. In this way, when the beam body is used to place luggage, the problem of luggage falling off due to the rotation of the connection column driving the beam body to rotate can be avoided. Since a plurality of first connection holes arranged at intervals along the circumferential direction are provided on the peripheral wall of the connection column, when the beam body needs to realize different functions, the first connection holes at different positions on the connection column can be arranged relative to the second connection holes by rotating the beam body, so that the first fastener can be used for subsequent fixing.

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

[0015] According to the above technical means, when the beam body is used to place luggage, the fixing member can be located above the beam body. In this way, the slide groove on the fixing member can be used to make a part of the luggage stuck in the slide groove, so as to facilitate the positioning and fixing of the luggage box.

[0016] In a possible implementation, the energy absorbing assembly further includes at least one energy absorbing member. The interior of the energy absorbing member is hollow, and openings are formed at both ends. The energy absorbing member is arranged between the connecting sleeve and the mounting member. The connecting sleeve and the mounting member are respectively located on one side of the openings at both ends of the energy absorbing member.

[0017] According to the above technical means, when a vehicle collides, since the energy absorbing member is hollow inside, it can deform after being hit to absorb energy, thereby reducing the impact force on the vehicle body and providing good protection for the vehicle body. At the same time, it is understandable that when the energy absorbing member is set on the vehicle body, the openings at both ends of the energy absorbing member can be set at intervals along the length direction of the vehicle body. In this way, the side where the opening at one end of the energy absorbing member is located is hit first, which can better cause the energy absorbing member to deform and achieve a better energy absorption effect.

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

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

[0020] In a possible implementation, a third connection hole is provided at one end of the beam body away from the connection column. The connection assembly includes a connection member and a second fastener. A plurality of fourth connection holes are provided on the connection member. The second fastener is inserted into the third connection hole and the fourth connection hole. The connection member is connected to the beam body through the second fastener.

[0021] According to the above technical means, the connection between the connecting component and the beam body can be achieved by inserting the second fastener into the third connecting hole and the fourth connecting hole.

[0022] In a possible implementation manner, there are a plurality of third connection holes, and the plurality of third connection holes are arranged at intervals along the extension direction of the beam body.

[0023] According to the above technical means, when two beam bodies do not need to be connected to each other using a connecting assembly, the connection position of the connecting piece on the beam body can be changed so that the connecting piece can be hidden under the beam body, which is convenient for the placement of the connecting piece.

[0024] In a possible implementation, the connecting member includes a first connecting member, a second connecting member and a third fastener. The first connecting member is provided with a fifth connecting hole. The second connecting member is provided with a sixth connecting hole. The third fastener is inserted into the fifth connecting hole and the sixth connecting hole. The first connecting member is connected to the second connecting member through the third fastener. The first connecting member and the second connecting member are both provided with a fourth connecting hole.

[0025] According to the above 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 connecting hole and the sixth connecting hole. At the same time, by providing the first connector and the second connector, when connecting two beam bodies, the first connector and the second connector can be pre-installed on the two beam bodies respectively, and then the installation between the first connector and the second connector can be completed, which makes the connection more convenient.

[0026] In a possible implementation, a concave portion is formed on a surface of one side of the first connecting member, and a convex portion is formed on a surface of one side of the second connecting member, and the convex portion is located in the concave portion.

[0027] According to the above technical means, when the first connecting member and the second connecting member are installed, they can be positioned by the raised portion and the recessed portion to facilitate subsequent installation.

[0028] In a second aspect, an embodiment of the present application provides a vehicle comprising any rear anti-collision beam assembly in the first aspect.

[0029] Since the vehicle provided in the embodiment of the present application includes any one of the rear anti-collision beam assemblies in the first aspect, it can solve the same technical problems as the above-mentioned rear anti-collision beam assemblies and achieve the same technical effects, which will not be repeated here.

DETAILED DESCRIPTION

[0035] In order to enable ordinary persons in the art to better understand the technical solution of the present application, the technical solution 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", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.

[0037] The rear anti-collision beam of a car is usually set at the rear of the car body, below the trunk door. When the rear of the vehicle collides, the rear anti-collision beam can absorb and disperse the impact force generated during the collision, so that the rear of the car body is not prone to major deformation, thereby playing a certain protective role for passengers.

[0038] As users' demands for cars become higher and higher, the demand for car diversification continues to increase. For example, users' demands for car space are gradually increasing to meet their needs for large passenger space and high storage capacity. In particular, there is a further demand for the use of space outside the car, hoping to make more efficient use of the external space of the car body.

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

[0040] In order to realize the basic functions of a car, the vehicle may include components such as a body, a chassis, a power system, and an electrical system.

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

[0042] The chassis may include components such as a transmission system and a drive system. The drive system can drive the wheels to rotate. Depending on the drive mode of the drive system, the drive system can be divided into front-wheel drive, rear-wheel drive, and four-wheel drive arrangements. The transmission system can transfer 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 basic driving functions. Depending on the type of vehicle, the composition of the power system is also different. Exemplarily, when the vehicle is an electric vehicle, the power system may include an electric motor.

[0044] In addition, the vehicle provided in the embodiment of the present application may further include a rear anti-collision beam assembly, which can be used to be installed on the vehicle. Exemplarily, the rear anti-collision beam assembly can be installed at the rear of the vehicle body. Among them, the rear anti-collision beam assembly provided in the embodiment of the present application can meet the user's demand for a multifunctional rear anti-collision beam.

[0045] The following is a detailed description of the rear anti-collision beam assembly provided in the embodiment of the present application. Figure 1 As shown, the rear anti-collision beam assembly 100 may include two anti-collision beam bodies 10 and a connecting assembly 40. The anti-collision beam body 10 may include a support beam 20 and a mounting seat 30. The mounting seat 30 may be mounted on a vehicle. In this way, the anti-collision beam body 10 may be mounted on a vehicle through the mounting seat 30 to achieve 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 in the embodiment of the present application, when the rear anti-collision beam assembly 100 needs to play the role of anti-collision energy absorption, such as Figure 1As shown, the connection assembly 40 can connect the two support beams 20 to each other to form a complete anti-collision beam structure. At this time, the rear anti-collision beam assembly 100 can play the role of anti-collision and energy absorption. When the user needs to place luggage or other items, the connection assembly 40 can be removed from the two support beams 20. At this time, since the support beams 20 are rotatably 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, Figure 2 As shown, the two support beams 20 can form an overlap space, and the luggage box can be placed on the two support beams 20. At this time, the rear anti-collision beam assembly 100 can play the role of placing luggage.

[0048] For example, Figure 1 As shown, when the rear anti-collision beam assembly 100 needs to play the role of anti-collision energy absorption, the ends 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 this way, the two support beams 20 can form a long strip structure as a whole, which plays a good role in anti-collision. 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] like Figure 2 As shown, when the rear anti-collision beam assembly 100 needs to carry luggage, the two support beams 20 can be arranged in parallel and spaced apart. The support beams 20 can extend along the length direction of the vehicle body. At this time, the two support beams 20 can provide a place 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 cargo carrying function of the rear anti-collision beam assembly 100.

[0050] In some embodiments, Figure 3 As shown, Figure 3 An exploded view of a rear anti-collision beam assembly 100 provided in an embodiment of the present application, wherein the mounting seat 30 may include a mounting member 31 and an energy absorbing assembly 32. The mounting member 31 may be mounted on a vehicle. Thus, the mounting seat 30 may be mounted on a vehicle body through the mounting member 31 to achieve installation of the mounting seat 30.

[0051] For example, Figure 3 As shown, the mounting member 31 may be a plate-like structure. Among them, a mounting hole 311 may be provided on the mounting member 31. At the same time, a mounting hole may also be provided on the vehicle body. At this time, the mounting member 31 may be mounted on the vehicle body by bolts to achieve the installation of the mounting member 31 on the vehicle body.

[0052] For example, Figure 3As shown, there can be multiple mounting holes 311. Through multiple mounting holes 311, the mounting member 31 can be more firmly mounted on the vehicle body, ensuring the mounting firmness of the mounting member 31.

[0053] It is understandable that the shape of the mounting member 31 can be designed according to actual conditions. Figure 3 As shown, the mounting member 31 as a whole can be a U-shaped plate-like structure. Among them, a notch 312 can be formed on the side of the mounting member 31. In this way, the notch 312 can be used to avoid other structures of the vehicle body, making it convenient to install the mounting member 31.

[0054] In addition, for example, Figure 3 As shown, the mounting member 31 may also be formed with a reinforcing rib 313. The reinforcing rib 313 may improve the overall strength of the mounting member 31, thereby ensuring the use strength of the mounting member 31. For example, the reinforcing rib 313 may be provided around the mounting hole 311. In this way, the reinforcing rib 313 may improve the strength of the mounting member 31 at the connection position with the vehicle body, thereby 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 an external impact, the energy absorbing assembly 32 can absorb energy, so that the rear anti-collision beam assembly 100 can absorb energy better, thereby improving the energy absorption and anti-collision performance of the rear anti-collision beam assembly 100. Among them, the support beam 20 can be rotatably connected to the energy absorbing assembly 32. Of course, in other embodiments, the mounting seat 30 may not include the energy absorbing assembly 32. At this time, the support beam 20 can be directly rotatably connected to the mounting member 31.

[0056] In order to realize the rotation connection between the support beam 20 and the energy absorbing assembly 32. Figure 3 As shown, in some embodiments, the support beam 20 may 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 may include a connecting sleeve 321. The connecting sleeve 321 may form an installation cavity with an opening. The connecting column 22 may be located in the installation cavity and rotatably connected to the connecting sleeve 321.

[0057] Since the connecting column 22 is disposed in the connecting sleeve 321, the connecting column 22 can rotate in the connecting sleeve 321, thereby driving the beam body 21 connected to the connecting column 22 to rotate. When luggage needs to be placed, the two beam bodies 21 can be rotated to form a placement position, and the luggage can be placed on the two beam bodies 21.

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

[0059] Of course, the support beam 20 can also be rotatably connected in other ways. For example, in other embodiments, a shaft hole can be provided on the beam body 21, and the energy absorbing assembly 32 can include a shaft. In this case, the shaft can be sleeved in the shaft hole. In this way, the rotatable connection between the beam body 21 and the energy absorbing assembly 32 can also be achieved. The specific design can be based on actual conditions, and is only described as an example here.

[0060] In some embodiments, Figure 3 As shown, a plurality of first connection holes 221 spaced apart along the circumferential direction may be provided on the peripheral wall of the connection column 22. At the same time, a second connection hole 3211 is provided on the peripheral wall of the connection sleeve 321. The rear anti-collision beam assembly 100 further includes a first fastener (not shown in the figure). The first fastener is inserted into the first connection hole 221 and the second connection hole 3211 to prevent the connection column 22 and the connection sleeve 321 from rotating relative to each other.

[0061] Thus, when the first fastener is inserted into the first connection hole 221 and the second connection hole 3211, the connection sleeve 321 and the connection 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 of the beam body 21 rotating due to the rotation of the connection column 22 driving the beam body 21 to rotate, which can prevent the luggage from falling off, can be avoided.

[0062] Since a plurality of first connection holes 221 are arranged at intervals along the circumferential direction on the peripheral wall of the connection column 22, when the beam body 21 needs to realize different functions, the beam body 21 can be rotated so that the first connection holes 221 and the second connection holes 3211 at different positions on the connection column 22 are arranged opposite to each other, so that the first fastener can be used for subsequent fixing.

[0063] For example, the number of the first connection holes 221 may be two. The angle formed between the two first connection holes 221 and the axis of the connection column 22 may be 90 degrees. In this way, after the beam body 21 rotates 90 degrees, another first connection hole 221 may be arranged opposite to the second connection hole 3211, and then the connection sleeve 321 and the connection column 22 may be fixed by the first fastener.

[0064] In some embodiments, continue to refer to Figure 3, the support beam 20 may further include a fixing member 23. The fixing member 23 is connected to the beam body 21 and is located on one side of the beam body 21. A slide groove 231 is formed on the surface of the fixing member 23 away from the side of the beam body 21. Thus, when the beam body 21 is used to place luggage, the fixing member 23 may be located above the beam body 21. In this way, the slide groove 231 on the fixing member 23 may be used to allow a portion of the luggage to be stuck in the slide groove 231, so as to facilitate the positioning and fixing of the luggage. In addition, exemplarily, when the luggage is placed on the beam body 21, the luggage may be tied to the beam body 21 by tools such as ropes to better achieve the placement of the luggage. In addition, exemplarily, the fixing member 23 may be mounted on the beam body 21 by bolts.

[0065] In some embodiments, Figure 3 As shown, along the extension direction of the slide groove 231, one end of the slide groove 231 can penetrate the fixing member 23. In this way, when a part of the luggage case is placed in the slide groove 231, it can be placed directly from one end of the slide groove 231, without lifting the luggage from the top of the slide groove 231 and placing it in the slide groove 231, which is more convenient. Of course, in other embodiments, the support beam 20 may not be provided with the fixing member 23. In this case, the luggage case can be placed directly on the beam body 21.

[0066] In order to better achieve the energy absorption effect of the energy absorption component 32, as Figure 3 As shown, in some embodiments, the energy absorbing assembly 32 may further include at least one energy absorbing member 322. The interior of the energy absorbing member 322 is hollow, and openings are formed at both ends. The energy absorbing member 322 is disposed between the connecting sleeve 321 and the mounting member 31. The connecting sleeve 321 and the mounting member 31 are respectively located on one side of the openings at both ends of the energy absorbing member 322.

[0067] In this way, when a vehicle collides, since the energy absorbing member 322 is hollow inside, the energy absorbing member 322 can be deformed after being hit to absorb energy, thereby reducing the impact force on the vehicle body and providing good protection for the vehicle body. At the same time, it can be understood that when the energy absorbing member 322 is arranged on the vehicle body, the openings at both ends of the energy absorbing member 322 can be arranged at intervals along the length direction of the vehicle body. In this way, the side where the opening at one end of the energy absorbing member 322 is located is hit first, which can better cause the energy absorbing member 322 to deform and achieve a better energy absorption effect.

[0068] It is understandable that the specific number of the energy absorbing members 322 can be set according to actual conditions. Figure 3As shown, two energy absorbing members 322 can be stacked in the vertical direction. In this way, the energy absorbing effect of the energy absorbing assembly 32 can be improved by multiple energy absorbing members 322, thereby improving the energy absorbing effect of the rear anti-collision beam assembly 100 and 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 described here as an example.

[0069] In some embodiments, Figure 3 As shown, the energy absorbing assembly 32 further includes a mounting plate 323. At least one energy absorbing member 322 and a connecting sleeve 321 are detachably connected to the mounting plate 323, respectively. The mounting plate 323 is also connected to the mounting member 31. Thus, the mounting plate 323 can provide a mounting position 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 through the mounting member 31.

[0070] The specific structure of the mounting plate 323 can be designed according to actual conditions. Figure 3 As shown, the mounting plate 323 may be in the form of a flat plate and is disposed below the energy absorbing member 322 and the connecting sleeve 321. Figure 3 As shown, the bolt 50 can penetrate the beam body 21, pass through the connecting column 22 and the connecting sleeve 321, and be connected to the mounting plate 323. In this way, the support beam 20 and the energy absorbing assembly 32 can be connected together by the bolt 50.

[0071] In some embodiments, a third connection hole 211 may be provided at one end of the beam body 21 away from the connection column 22. The connection assembly 40 includes a connection member 41 and a second fastener (not shown in the figure). A plurality of fourth connection holes 42 are provided on the connection member 41. The second fastener is inserted into the third connection hole 211 and the fourth connection hole 42. The connection member 41 is connected to the beam body 21 through the second fastener.

[0072] Thus, by inserting the second fastener into the third connection hole 211 and the fourth connection hole 42, the connection assembly 40 and the beam body 21 can be connected. Exemplarily, the number of the second fasteners is two. One second fastener is inserted into the third connection hole 211 of one beam body 21 and one fourth connection hole 42 of the connecting member 41, and the other second fastener is inserted into the third connection hole 211 of another beam body 21 and another fourth connection hole 42 of the connecting member 41. In this way, the two fasteners can realize the connection between the two beam bodies 21, and the connection is simple and convenient, and easy to achieve.

[0073] Of course, the connecting member 41 can also be connected to the beam body 21 in other ways, which can be specifically designed according to actual conditions, as long as the connection between the beam body 21 and the connecting member 41 can be achieved. This is only described as an example.

[0074] In some embodiments, Figure 3 As shown, the connecting member 41 includes a first connecting member 411, a second connecting member 412 and a third fastener (not shown in the figure). The first connecting member 411 is provided with a fifth connecting hole 4111. The second connecting member 412 is provided with a sixth connecting hole 4121. The third fastener is inserted into the fifth connecting hole 4111 and the sixth connecting hole 4121. The first connecting member 411 is connected to the second connecting member 412 through the third fastener. Among them, the first connecting member 411 and the second connecting member 412 are both provided with a fourth connecting hole 42. Thus, the connection between the first connecting member 411 and the second connecting member 412 can be achieved through the cooperation between the third fastener and the fifth connecting hole 4111 and the sixth connecting hole 4121. At the same time, by providing the first connecting member 411 and the second connecting member 412, when connecting the two beam bodies 21, the first connecting member 411 and the second connecting member 412 can be pre-installed on the two beam bodies 21 respectively, and then the installation between the first connecting member 411 and the second connecting member 412 can be completed, and the connection is more convenient.

[0075] In some embodiments, the number of the third connection holes 211 is multiple. The multiple third connection holes 211 are arranged at intervals along the extension direction of the beam body 21. In this way, when the two beam bodies 21 do not need to be connected to each other using the connection assembly 40, the connection position of the connection member 41 on the beam body 21 can be changed, so that the connection member 41 can be hidden under the beam body 21, which is convenient for the placement of the connection member 41. For example, Figure 3 As shown, the beam body 21 may be a U-shaped structure. In this way, the connecting member 41 may be better hidden inside the beam body 21.

[0076] In some embodiments, a concave portion is formed on the surface of one side of the first connecting member 411. A convex portion is formed on the surface of one side of the second connecting member 412. The convex portion is located in the concave portion. In this way, when the first connecting member 411 and the second connecting member 412 are installed, they can be positioned by the convex portion and the concave portion to facilitate subsequent installation.

[0077] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto, and any changes or substitutions within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
