[0040] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0041] See the figure below for reference Figure 1-Figure 11 A bent tube beam 100 according to an embodiment of the present invention is described, and the bent tube beam 100 can be applied to a vehicle.

[0042] Combination Figure 1 As shown, the bent tube beam 100 according to the embodiment of the utility model can mainly include: a bent tube beam body 1, wherein the drive shaft 7 is arranged to extend laterally, and the bent tube beam body 1 extends in the laterally direction, which can facilitate the arrangement and installation of other components on the bent tube beam 100.

[0043] Furthermore, the ends of the two sub-bent tube beam bodies 101 that are close to each other are detachably connected and fixed, so that the bent tube beam body 1 can be disassembled into two parts. During the assembly process of the bent tube beam body 1, one of the sub-bent tube beam bodies 101 can be installed separately. On the one hand, this can reduce the weight of the bent tube beam body 1 that needs to be lifted during the installation operation, and can easily adjust the position of the sub-bent tube beam body 101 to facilitate the assembly of other structural components on the sub-bent tube beam body 101. On the other hand, the weight of the sub-bent tube beam body 101 is smaller than that of the bent tube beam body 1, which can improve the safety of the sub-bent tube beam body 101 during assembly.

[0044] Furthermore, the bent tube beam body 1 is divided into two sub-bent tube beam bodies 101, and the two sub-bent tube beam bodies 101 are assembled separately, which can reduce the space occupied by welding tools when assembling the bent tube beam body 1, and can facilitate the installation of other components on the bent tube beam 100, which is beneficial to reducing the production space and production cost of the bent tube beam body 1.

[0045] After the two sub-bent tube beam bodies 101 are assembled, the two sub-bent tube beam bodies 101 are connected and fixed, so that a whole bent tube beam body 1 can be formed. The bent tube beam body 1 manufactured in this way not only meets the structural requirements of the bent tube beam 100, but also improves the convenience of disassembly and assembly of the bent tube beam body 1, thereby simplifying the production method of the bent tube beam body 1, which is conducive to reducing the production cost of the bent tube beam body 1.

[0046] Combination Figure 1-Figure 5 As shown, the ends of the two sub-bent tube beam bodies 101 close to each other are both provided with connecting flanges 2, one of the two connecting flanges 2 is provided with a first through hole 201, and the other is provided with a second through hole 202, the first through hole 201 and the second through hole 202 correspond to each other, and are connected and fixed by fasteners 207. Specifically, the connecting flange 2 can increase the end surface area of ​​one end of the sub-bent tube beam body 101, so that when the two sub-bent tube beam bodies 101 are connected and fixed by the two connecting flanges 2, the connection reliability between the two sub-bent tube beam bodies 101 can be increased, which is conducive to improving the connection strength of the connection position of the two sub-bent tube beam bodies 101, and can ensure the structural reliability of the bent tube beam body 1 in the bent tube beam 100, so that the bent tube beam 100 in the utility model can be applied to relatively severe off-road conditions.

[0047] Furthermore, the first through-hole 201 and the second through-hole 202 have simple structures and are convenient to be set on the connecting flange 2, which can improve the processing convenience of the curved tube beam body 1. After the two connecting flanges 2 arranged at the ends of the two sub-curved tube beam bodies 101 close to each other are arranged opposite to each other, the first through-hole 201 on one of the two connecting flanges 2 corresponds to the second through-hole 202 on the other connecting flange 2, so that the fastener 207 can pass through the first through-hole 201 and the second through-hole 202 in sequence to connect and fix the two connecting flanges 2, and then the ends of the two sub-curved tube beam bodies 101 close to each other can be connected and fixed, so that the two sub-curved tube beam bodies 101 are connected to form an integral curved tube beam body 1.

[0048] In this way, the two sub-bent tube beam bodies 101 are connected by fasteners 207, which can not only simplify the connection method of the two sub-bent tube beam bodies 101 and improve the assembly convenience of the bent tube beam body 1, but also ensure the connection reliability of the two sub-bent tube beam bodies 101, and prevent the two sub-bent tube beam bodies 101 from detaching during transportation and use, thereby ensuring the structural reliability of the bent tube beam 100.

[0049] When one of the two sub-bent tube beam bodies 101 fails, it is only necessary to loosen the fastener 207 to separate the two connecting flanges 2, so that one of the sub-bent tube beam bodies 101 can be disassembled, repaired and replaced. This arrangement can solve the problem in the prior art that the entire bent tube beam body 1 needs to be replaced when the bent tube beam body 1 fails. This not only facilitates the maintenance of the bent tube beam 100, but also improves the maintenance economy of the bent tube beam 100.

[0050] According to some embodiments of the utility model, the first through hole 201 and the second through hole 202 are both set as threaded holes, and the fastener 207 is a bolt. In this way, the first through hole 201 and the second through hole 202 can be locked or loosened at the same time by rotating the fastener 207, which can not only improve the convenience of disassembly and assembly of the two connecting flanges 2, but also ensure the connection reliability of the two connecting flanges 2, thereby realizing the convenience of disassembly and assembly and the connection reliability of the two sub-bent tube beam bodies 101.

[0051] According to other embodiments of the utility model, a first clamping portion is provided on one of the two connecting flanges 2, and a second clamping portion is provided on the other, so that the two connecting flanges 2 can be connected through the clamping cooperation of the first clamping portion and the second clamping portion, and the clamping effect is reliable. When the two connecting flanges 2 need to be disassembled, the first clamping portion and the second clamping portion can be easily separated. In this way, not only the convenience of disassembly and assembly of the two connecting flanges 2 can be improved, but also the connection reliability of the two connecting flanges 2 can be guaranteed, and then the convenience of disassembly and assembly and the connection reliability of the two sub-bent tube beam bodies 101 can be achieved.

[0052] Combination Figure 2-Figure 5 As shown, the first tooth portion 203 and the second tooth portion 204 are respectively provided on the side where the two connection flanges 2 are close to each other, and the first tooth portion 203 and the second tooth portion 204 are meshed with each other for transmission. Specifically, on the two opposite end faces of the two connection flanges 2, the first tooth portion 203 is provided on one end face, and the second tooth portion 204 is provided on the other end face, and the first tooth portion 203 and the second tooth portion 204 are meshed with each other, so that the two opposite end faces of the two connection flanges 2 can be fitted together, so that the first through hole 201 and the second through hole 202 correspond to each other.

[0053] When the curved tube beam body 1 is working, the two connecting flanges 2 bear a large part of the torsional force. If the friction between the two connecting flanges 2 is small, they will shift against each other, which may easily cause shear fracture of the fasteners 207 between the two connecting flanges 2. With such a configuration, when the first tooth portion 203 and the second tooth portion 204 are meshed with each other, the two tooth portions can limit each other, increasing the friction between the two connecting flanges 2, thus preventing the two connecting flanges 2 from shifting against each other, effectively improving the connection reliability of the two sub-curved tube beam bodies 101, and facilitating the improvement of the torque bearing capacity of the curved tube beam body 1.

[0054] According to an embodiment of the utility model, the distance between the tooth top of one of the first tooth portion 203 and the tooth root of the other tooth portion 204 in the lateral direction is D1, the radius of the tooth root circle of the other tooth portion 203 and the second tooth portion 204 is D2, and D1 and D2 satisfy the relationship: D1>D2. Specifically, the end faces of the two connecting flanges 2 are arranged perpendicular to the lateral direction of the drive shaft 7, and when the two connecting flanges 2 are close to each other, the tooth top of one of the first tooth portion 203 and the tooth root of the other tooth portion 204 are arranged opposite to each other in the lateral direction. The distance between the tooth top of one of the first tooth portion 203 and the tooth root of the other tooth portion 204 is set to be greater than the radius of the tooth root circle of the other tooth portion 203 and the second tooth portion 204.

[0055] With such arrangement, when the first tooth portion 203 and the second tooth portion 204 mesh with each other, in a pair of oppositely arranged tooth tops and tooth roots, the tooth groove side walls on both sides of the tooth tops and the tooth groove side walls on both sides of the tooth roots can be ensured to fit and press each other. This can prevent the two connecting flanges 2 from shifting relative to each other in a direction perpendicular to the axial direction, can prevent the curved tube beam body 1 from generating noise at the two connecting flanges 2, can slow down the wear and fatigue fracture of the teeth of the first tooth portion 203 and the second tooth portion 204, can increase the service life of the connecting flange 2, and further increase the service life of the curved tube beam body 1.

[0056] According to some embodiments of the utility model, the first tooth portion 203 and the second tooth portion 204 are helical tooth portions. In the embodiments of the utility model, the side of the first tooth portion 203 and the second tooth portion 204 away from the axis of the connecting flange 2 can be tilted relative to the side of the first tooth portion 203 and the second tooth portion 204 close to the axis of the connecting flange 2, and the inclination angle and inclination direction of the side of the first tooth portion 203 and the second tooth portion 204 away from the axis of the connecting flange 2 relative to the side of the first tooth portion 203 and the second tooth portion 204 close to the axis of the connecting flange 2 are the same, so that the first tooth portion 203 and the second tooth portion 204 are both helical tooth portions.

[0057] This not only ensures the meshing and pressing of the first tooth portion 203 and the second tooth portion 204, but also plays a positioning role on the axes of the two connecting flanges 2, so that the end faces of the two connecting flanges 2 can be quickly aligned, which can improve the connection convenience of the two sub-bent tube beam bodies 101.

[0058] According to other embodiments of the utility model, the first tooth portion 203 and the second tooth portion 204 are straight tooth portions. In the embodiments of the utility model, the first tooth portion 203 and the second tooth portion 204 can also be set as straight tooth portions, so that the side of the first tooth portion 203 and the second tooth portion 204 away from the axis of the connecting flange 2 can be arranged parallel to the side of the first tooth portion 203 and the second tooth portion 204 close to the axis of the connecting flange 2, which can facilitate the processing of the first tooth portion 203 and the second tooth portion 204, and improve the production convenience of the bent tube beam body 1.

[0059] Combination Figure 2-Figure 5 As shown, the first positioning portion 205 and the second positioning portion 206 are respectively provided on the side where the two connecting flanges 2 are close to each other. The first positioning portion 205 is a positioning protrusion, and the second positioning portion 206 is a positioning groove. The other positioning groove and the positioning protrusion are positioned and matched.

[0060] Specifically, the two connecting flanges 2 are positioned and matched by the first positioning portion 205 and the second positioning portion 206, which is actually positioned and matched by the positioning protrusion and the positioning groove. Such a configuration can simplify the processing method of the first positioning portion 205 and the second positioning portion 206 on the two connecting flanges 2 on the one hand, and can position the axes of the two connecting flanges 2 on the other hand, so that after the two connecting flanges 2 are connected, the coaxiality requirement of the two sub-bent tube beam bodies 101 can be met.

[0061] In addition, the positioning cooperation of the positioning protrusion and the positioning groove can avoid the problem of misalignment of the first through hole 201 and the second through hole 202 when the two connecting flanges 2 are installed, which is beneficial to improving the installation convenience of the two connecting flanges 2.

[0062] In an embodiment of the utility model, a chamfer can be set on at least one of the outer extensions of the positioning protrusion and the positioning groove, so that the positioning protrusion and the positioning groove can be quickly positioned and matched, and then the two connecting flanges 2 can be installed, and the two sub-bent tube beam bodies 101 can be quickly assembled to improve the assembly convenience of the bent tube beam body 1.

[0063] Combination Figure 2-Figure 5As shown, the positioning protrusion and the positioning groove are both annular, which can ensure the structural strength of the positioning protrusion and the positioning groove on the two connecting flanges 2, and ensure the matching reliability of the positioning protrusion and the positioning groove. The first tooth portion 203 is circumferentially arranged on the outside of the positioning protrusion, and the second tooth portion 204 is circumferentially arranged on the outside of the positioning groove, which can not only enhance the friction between the two connecting flanges 2, but also avoid the setting of the first tooth portion 203 and the second tooth portion 204 to interfere with the positioning protrusion and the positioning groove, which can ensure the positioning reliability of the positioning protrusion and the positioning groove, and further ensure the coaxiality requirements of the two sub-bend tube beam bodies 101 in the bend tube beam body 1.

[0064] Combination Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 As shown, the ends of the two sub-bend tube beam bodies 101 that are close to each other are provided with covers 3 and connecting ribs 4, one side of the covers 3 is positioned and matched with the sub-bend tube beam body 101, and are connected to each other, the other side of the covers 3 is positioned and matched with the connecting ribs 4, and are connected to each other, and the side of the connecting ribs 4 facing away from the covers 3 is positioned and matched with the connecting flange 2, and are connected to each other.

[0065] Specifically, one of the cover 3 and the sub-bend tube beam body 101 is provided with a pin 5, and the other is provided with a pin hole 6, so that the cover 3 and the sub-bend tube beam body 101 are positioned and matched. This not only facilitates the assembly of the cover 3 and the sub-bend tube beam body 101, but also can seal the ends of the two sub-bend tube beam bodies 101 that are close to each other, which can play a role in waterproofing and dustproofing.

[0066] Furthermore, a pin 5 is provided on one of the sides of the cover 3 away from the sub-bent tube beam body 101 and the connecting rib 4, and a pin hole 6 is provided on the other side, so that the connecting rib 4 and the cover 3 are positioned and matched. This not only facilitates the assembly of the connecting rib 4 and the cover 3, but also allows the length of the bent tube beam body 1 to be changed by changing the length of the connecting rib 4. Such a setting can not only change the wheelbase of the vehicle and facilitate modification, but also is conducive to the platformization of vehicle components, which can reduce the cost of vehicle development.

[0067] Furthermore, a pin 5 is provided on one of the connecting flanges 2 on the side of the connecting rib 4 away from the cover 3, and a pin hole 6 is provided on the other side to position and match the connecting flange 2 and the connecting rib 4. This facilitates the assembly of the connecting flange 2 and the connecting rib 4 and improves the assembly convenience of the bent tube beam body 1.

[0068] In the embodiment of the present utility model, after positioning, the cover 3 and the sub-bend tube beam body 101, the connecting rib 4 and the cover 3, and the connecting flange 2 and the connecting rib 4 all need to be connected and fixed by methods including but not limited to welding to ensure the structural reliability of the bent tube beam body 1.

[0069] It should be noted that in the process of connecting the sub-bent tube beam body 101, the cover 3, the connecting rib 4 and the connecting flange 2, the number of the pins 5 and the pin holes 6 can be set according to actual needs. The number of ribs 401 on the connecting rib 4 can be set according to actual needs.

[0070] In the embodiment of the present invention, the pin hole 6 and the pin 5 are used for positioning, so as to ensure the installation coaxiality of the two sub-bend tube beam bodies 101, and further ensure the coaxiality requirement of the steering knuckle 8 on the ends of the two sub-bend tube beam bodies 101 that are away from each other. After the wheels are installed, the coaxiality error of the left and right wheels in the present invention can be reduced.

[0071] According to the embodiment of the utility model, a toothed disc is provided between the two connecting flanges 2, so that the user can modify the lateral dimension of the bent tube beam body 1 according to the needs, thereby changing the wheelbase of the vehicle and improving the modifiability of the vehicle.

[0072] According to an embodiment of the utility model, the curved tube beam 100 can be applied to a vehicle. The vehicle equipped with the curved tube beam 100 of the utility model is configured by dividing the curved tube beam body 1 into two sub-curved tube beam bodies 101, and the two sub-curved tube beam bodies 101 are detachably connected and fixed, so that the individual sub-curved tube beam bodies 101 can be assembled separately, and there is no need to hoist and adjust the position of the curved tube beam body 1 to achieve installation. On the one hand, it can reduce the floor space occupied during the assembly of the curved tube beam body 1, save the rear axle layout space, save production space and cost, and on the other hand, it can improve the convenience and safety of disassembly and assembly of the curved tube beam body 1. In addition, when one of the sub-curved tube beam bodies 101 fails, only one sub-curved tube beam body 101 needs to be replaced, which can reduce the maintenance cost and improve the maintenance economy.

[0073] Furthermore, the vehicle further includes two steering knuckles 8, two wheel hub bearings 11, a drive shaft 7 and a drive member 12, wherein the two steering knuckles 8 are respectively arranged at the two ends of the two sub-bent tube beam bodies 101 that are far away from each other, so that the shock absorber is arranged at the lateral ends of the bent tube beam body 1. The two wheel hub bearings 11 are respectively arranged at the two steering knuckles 8, so that the wheels are connected to the lateral sides of the bent tube beam 100. The drive shaft 7 is extended in the lateral direction and is located on one longitudinal side of the bent tube beam 100. There are two drive shafts 7, and the ends of the two drive shafts 7 that are far away from each other in the lateral direction are respectively connected to the two wheel hub bearings 11. This not only facilitates the arrangement of the drive shaft 7 and the bent tube beam 100, but also transmits power to the wheel hub bearings 11 on the lateral sides of the bent tube beam 100 to drive the wheels on the lateral sides of the vehicle to rotate.

[0074] Furthermore, the driving member 12 is arranged on one longitudinal side of the curved tube beam body 1 and between the ends of the two drive shafts 7 that are close to each other, so that the driving member 12 can be arranged close to the curved tube beam 100, which can improve the compactness of the arrangement of the driving member 12 and the axle. The driving member 12 is connected to the two drive shafts 7 respectively, and can output power to the two drive shafts 7 respectively, so that the power can be transmitted along the drive shafts 7 toward the wheel hub bearings 11 at the two lateral ends to simultaneously drive the wheels on both sides of the vehicle to rotate, thereby ensuring the normal operation of the vehicle.
