The rear bumper of the vehicle is mounted to the rear of the vehicle through a rear bumper bracket. The rear bumper bracket also includes a rear bumper side bracket and a rear bumper middle bracket.
在安装车辆后保险杠之后，后保险杠与后保险杠中支架之间通常会存在重叠区域。当与后面的车辆发生撞击时，后保险杠极有可能发生变形而对后保险杠中支架产生冲击，进而在车辆之间的撞击期间产生的壁障能量可能传递至中支架而对车身产生影响。因此，在传统的项目中，通常将后保险杠与后保险杠中支架之间的重叠区域切除，使得即使发生撞击，后保险杠也不能与中支架接触，从而防止撞击期间产生的壁障能量被传递至车身。然而，对于现有技术中的方案，由于后保险杠与后保险杠中支架之间的重叠部分被切除，因此中支架不能很好地对后保险杠壳体进行支撑，从而不能满足后保险杠的刚度需求。After the rear bumper of a vehicle is installed, there is usually an overlap area between the rear bumper and the bracket in the rear bumper. When a collision occurs with a vehicle behind, the rear bumper is very likely to deform and impact the bracket in the rear bumper, and the barrier energy generated during the collision between vehicles may be transferred to the center bracket and affect the vehicle body. . Therefore, in traditional projects, the overlapping area between the rear bumper and the bracket in the rear bumper is usually cut off, so that even if a collision occurs, the rear bumper cannot contact the middle bracket, thereby preventing the barrier energy generated during the impact. Passed to the body. However, for the solutions in the prior art, since the overlapping portion between the rear bumper and the rear bracket of the rear bumper is cut off, the middle bracket cannot support the rear bumper housing well, so that the rear bumper cannot be satisfied.

为使本申请实施例的目的、技术方案和优点更加清楚，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请的一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动的前提下所获得的所有其他实施例，都属于本申请保护的范围。In order to make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments These are part of the embodiments of this application, but not all of them. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.
一方面，如图1至4所示，本申请提供了一种车辆后保险杠中支架，设置于车辆的后部，车辆后保险杠中支架与车体固定连接且与车辆后保险 杠卡扣连接，该车辆后保险杠中支架包括具有基部和至少一个支撑件的中支架本体，基部具有数量与支撑件的数量相对应的至少一个镂空部分，支撑件在相应镂空部分的上下两侧处与基部连接，并且支撑件在车辆的倒车方向上、从镂空部分向外突出，其中当车辆的后部发生撞击时，支撑件受力而相对于基部向下旋转并且支撑件的至少一部分断裂。In one aspect, as shown in FIGS. 1 to 4, the present application provides a bracket in a rear bumper of a vehicle, which is disposed at the rear of the vehicle. The bracket in the rear bumper of the vehicle is fixedly connected to the vehicle body and is buckled with the rear bumper of the vehicle. The rear bracket of the vehicle includes a middle bracket body having a base and at least one support. The base has at least one hollow portion corresponding to the number of the support. The support is connected to the upper and lower sides of the corresponding hollow portion. The base is connected, and the support protrudes outward from the hollowed out portion in the reverse direction of the vehicle, wherein when the rear part of the vehicle collides, the support is forced to rotate downward relative to the base and at least a part of the support is broken.
在本实施例中，车辆后保险杆中支架被设置为包括基部2和支撑件3的中支架本体1。基部2可设置为沿车辆的高度方向和宽度方向延伸，并且可在基部2中设置有连接孔5和卡扣结构6。基部2可通过连接孔5与车体进行固定连接，能够方便快捷地实现与车辆车身连接，同时通过卡扣结构6与车辆后保险杠进行卡扣连接，以实现车辆后保险杆中支架分别与车体和车辆后保险杠的连接。In the present embodiment, the middle bracket of the rear bumper of the vehicle is provided as a middle bracket body 1 including a base 2 and a support 3. The base 2 may be provided to extend in a height direction and a width direction of the vehicle, and a connection hole 5 and a buckle structure 6 may be provided in the base 2. The base 2 can be fixedly connected to the vehicle body through the connection hole 5 and can be easily and quickly connected to the vehicle body. At the same time, it can be snap-connected to the rear bumper of the vehicle through the buckle structure 6 to realize the bracket in the rear bumper of the vehicle and The connection between the body and the rear bumper of the vehicle.
同时，可在基部2中设置至少一个镂空部分4，镂空部分4的数量可对应于支撑件3的数量，使得一个支撑件3连接至相应的一个镂空部分4。具体地，支撑件3可在相应镂空部分4的上下两侧处分别与镂空部分4连接，并且支撑件3可在车辆的倒车方向上、从镂空部分4向外突出。由于在基部2中设置有镂空部分4，而镂空部分4使得其所在位置处的支撑力较为脆弱，因此当车辆的后部发生撞击时，支撑件3更易于发生向下旋转，从而吸收壁障能量以防止车辆内部的其他部件(例如，后围板)的损坏。此外，设置至少一个镂空部分4可有利于减轻车辆后保险杆中支架的重量，进而能够减少汽车的整体重量，因此能够实现轻量化且降低成本，经济性好，实用性强。根据本申请实施例的镂空部分4可形成为类似四边形的形状，然而实施例可不限于此，可根据车辆的内部设计要求而相应地任意设计镂空部分4的形状。At the same time, at least one hollow portion 4 may be provided in the base portion 2, and the number of the hollow portions 4 may correspond to the number of the support members 3, so that one support member 3 is connected to the corresponding one hollow portion 4. Specifically, the support 3 may be connected to the hollow portion 4 at the upper and lower sides of the corresponding hollow portion 4 respectively, and the support 3 may protrude outward from the hollow portion 4 in the reverse direction of the vehicle. Since the hollow part 4 is provided in the base part 2, and the hollow part 4 makes the supporting force at the position weaker, when the rear part of the vehicle collides, the support part 3 is more likely to rotate downward, so as to absorb the barrier Energy to prevent damage to other components inside the vehicle, such as the tailgate. In addition, the provision of at least one hollowed-out portion 4 can help reduce the weight of the bracket in the rear bumper of the vehicle, thereby reducing the overall weight of the car, so it can achieve light weight and reduce costs, with good economy and strong practicability. The hollowed-out portion 4 according to the embodiment of the present application may be formed into a quadrangular shape, but the embodiment may not be limited thereto, and the shape of the hollowed-out portion 4 may be arbitrarily designed according to the internal design requirements of the vehicle.
进一步地，如图1至5所示，支撑件包括彼此连接的第一部和第二部，第一部在镂空部分的上侧与基部连接以及第二部在镂空部分的下侧与基部连接。当车辆的后部发生撞击时，至少第二部断裂。Further, as shown in FIGS. 1 to 5, the supporting member includes a first portion and a second portion connected to each other, the first portion is connected to the base portion on the upper side of the hollow portion, and the second portion is connected to the base portion on the lower side of the hollow portion. . When the rear part of the vehicle collided, at least the second part broke.
根据本申请的实施例，支撑件3包括第一部3-1和第二部3-2。第一部3-1具有第一板11、第二板12、第三板13以及第四板14。第四板14的一侧可与镂空部分4的上侧连接，而第一板11、第二板12和第三板13分别从第四板14的其余三侧处向下斜向延伸，同时第二板12和第三板13 中的每个的一侧与镂空部分4连接，并且第二板12和第三板13中的每个的另一侧与第一板11连接，使得第一部3-1可形成为一个连接至镂空部分4的内凹腔体。第一部3-1可成角度地与基部2连接，可根据车辆的内部设计需要而任意设置第一部3-1与基部2之间的角度，只要该角度能够使得在发生车辆撞击期间，支撑件3可受力而发生相对于基部2的向下旋转，并且至少第二部3-2发生断裂以吸收壁障能量。According to an embodiment of the present application, the support 3 includes a first portion 3-1 and a second portion 3-2. The first portion 3-1 includes a first plate 11, a second plate 12, a third plate 13, and a fourth plate 14. One side of the fourth plate 14 may be connected to the upper side of the hollow portion 4, and the first plate 11, the second plate 12, and the third plate 13 extend obliquely downward from the remaining three sides of the fourth plate 14, respectively, and One side of each of the second plate 12 and the third plate 13 is connected to the hollow portion 4, and the other side of each of the second plate 12 and the third plate 13 is connected to the first plate 11 such that the first The portion 3-1 may be formed as a concave cavity connected to the hollow portion 4. The first part 3-1 can be connected to the base part 2 at an angle, and the angle between the first part 3-1 and the base part 2 can be arbitrarily set according to the internal design needs of the vehicle, as long as the angle can make it possible during a vehicle collision, The support 3 can be rotated downward relative to the base 2 under a force, and at least the second portion 3-2 can be broken to absorb the energy of the barrier.
根据本申请的实施例，第二部3-2的一端可连接至第一部3-1的第一板11，并且另一端可连接至镂空部分4的下侧。优选地，第二部3-2连接至第一板11的中间位置处，使得车辆后保险杆中支架的结构更为稳定，而且在发生车辆撞击期间，使得第二部3-2的受力均匀以易于发生断裂，从而防止壁障能量传递至车身。可根据车辆的内部设计需要而任意设置第二部3-2的厚度、宽度及韧性，只要该厚度、宽度及韧性能够使得在发生车辆撞击期间，当支撑件3受力而发生向下旋转时，第二部3-2可发生断裂以使得旋转后的支撑件3吸收壁障能量而防止壁障能量传递至车身。According to an embodiment of the present application, one end of the second portion 3-2 may be connected to the first plate 11 of the first portion 3-1, and the other end may be connected to a lower side of the hollow portion 4. Preferably, the second portion 3-2 is connected to the middle position of the first plate 11, so that the structure of the bracket in the rear bumper of the vehicle is more stable, and the force of the second portion 3-2 is caused during the vehicle collision. Uniform to facilitate breakage, thereby preventing barrier energy from being transmitted to the vehicle body. The thickness, width, and toughness of the second part 3-2 can be arbitrarily set according to the needs of the vehicle's internal design, as long as the thickness, width, and toughness can enable the support 3 to rotate downwards under force during a vehicle collision The second part 3-2 may be broken so that the rotated support member 3 absorbs the barrier energy and prevents the barrier energy from being transmitted to the vehicle body.
进一步地，如图4所示，在车辆的高度方向上，支撑件对后保险杠的壳体进行支撑。Further, as shown in FIG. 4, the support member supports the housing of the rear bumper in the height direction of the vehicle.
根据本申请的实施例，当完成安装后保险杠支架和后保险杠时，在车辆的高度方向上，支撑件3中的第一部3-1可与后保险杠(未示出)的壳体重叠。具体地，当后保险杠通过卡扣结构与车辆后保险杆中支架连接后，在车辆的高度方向上，支撑件3中的第一部3-1中的第一板11可被后保险杠壳体覆盖。也就是说，在车辆的高度方向上，第一板11可形成在后保险杠壳体下方，使得当车辆的后部没有发生撞击时，支撑件3可用于在车辆的高度方向上支撑后保险杠壳体，从而保证后保险杠壳体的刚度。同时，在车辆的高度方向上，第二部3-2对第一部3-1进行支撑，从而进一步地对后保险杠壳体进行支撑，以加强支撑件3对后保险杠壳体的支撑作用。According to the embodiment of the present application, when the installation of the rear bumper bracket and the rear bumper is completed, in a height direction of the vehicle, the first portion 3-1 of the support 3 may be connected with a housing of a rear bumper (not shown). Body overlap. Specifically, after the rear bumper is connected with the bracket in the rear bumper of the vehicle through the buckle structure, in the height direction of the vehicle, the first plate 11 in the first portion 3-1 of the support 3 can be used by the rear bumper. Shell cover. That is, in the height direction of the vehicle, the first plate 11 may be formed under the rear bumper housing, so that when the rear part of the vehicle does not collide, the support 3 can be used to support the rear fuse in the height direction of the vehicle. Bumper housing to ensure the rigidity of the rear bumper housing. At the same time, in the height direction of the vehicle, the second section 3-2 supports the first section 3-1, thereby further supporting the rear bumper shell to strengthen the support 3 to support the rear bumper shell. effect.
然而，当车辆的后部发生撞击时，后面车辆将以高速撞击后保险杠壳体，这将使后保险杠壳体由于撞击而发生向车辆内部凹陷的变形。由于在后保险杠壳体和支撑件3之间存在重叠区域，因此在后保险杠壳体发生向内凹陷变形的同时，也对支撑件3施加力，这将使得支撑件3由于受力而发生向下旋转。具体地，当支撑件3向下旋转时，可发生仅第二部3-2断 裂，或者支撑件3的第一部3-1和第二部3-2同时发生断裂。However, when a collision occurs at the rear of the vehicle, the rear vehicle will hit the rear bumper housing at high speed, which will cause the rear bumper housing to be deformed into the interior of the vehicle due to the impact. Because there is an overlapping area between the rear bumper housing and the support 3, when the rear bumper housing is deformed inwardly, a force is also applied to the support 3, which will cause the support 3 to be affected by the force. A downward rotation occurs. Specifically, when the support member 3 is rotated downward, only the second portion 3-2 may be broken, or the first portion 3-1 and the second portion 3-2 of the support 3 may be broken at the same time.
此外，如图4-5所示，在根据本申请的实施例中，可在支撑件3中的第一部3-1中的第二板12和第三板13分别设置有旋转点50，使得当第一部3-1受力时，第二板12和第三板13通过旋转点50而发生旋转。具体地，根据本申请的实施例，以第一部3-1中的第二板12为示例，第二板12的下侧可设置为曲线形状，也就是说，第二板12的下侧上的每一点与第四板14之间的垂直距离可不相同，其中在第二板12的下侧上的所有点之中，将距第四板14的垂直距离最小的点设置为旋转点50。例如，第一部3-1的旋转点50距第四板14的垂直距离为H1，而第一部3-1的其他点60距第四板14的垂直距离为H2，并且如图4所示，H1小于H2。类似地，第一部3-1中的第三板13可以以与第二板12相同的方式设置旋转点50。由于在第二板12和第三板13中分别设置了旋转点50，而在旋转点50处可发生应力集中现象，因此当车辆的后部发生撞击而使支撑件3受力时，在旋转点50处更易于发生向下旋转，以更有利于使支撑件3进行向下旋转，从而实现防止壁障能量传递至车身。In addition, as shown in FIGS. 4-5, in the embodiment according to the present application, the second plate 12 and the third plate 13 in the first portion 3-1 in the support 3 may be respectively provided with rotation points 50, When the first part 3-1 is stressed, the second plate 12 and the third plate 13 are rotated by the rotation point 50. Specifically, according to the embodiment of the present application, taking the second plate 12 in the first part 3-1 as an example, the lower side of the second plate 12 may be set in a curved shape, that is, the lower side of the second plate 12 The vertical distance between each point on the fourth plate 14 may be different, and among all points on the lower side of the second plate 12, the point with the smallest vertical distance from the fourth plate 14 is set as the rotation point 50 . For example, the vertical distance between the rotation point 50 of the first part 3-1 and the fourth plate 14 is H1, and the other points 60 of the first part 3-1 are vertical distance from the fourth plate 14 as H2, and as shown in FIG. 4 It shows that H1 is smaller than H2. Similarly, the third plate 13 in the first portion 3-1 may set the rotation point 50 in the same manner as the second plate 12. Since the second plate 12 and the third plate 13 are respectively provided with a rotation point 50, and a stress concentration phenomenon may occur at the rotation point 50, when a collision occurs at the rear of the vehicle and the support 3 is stressed, the rotation occurs in the rotation. The downward rotation is more likely to occur at the point 50, so as to facilitate the downward rotation of the support 3, thereby preventing the barrier energy from being transmitted to the vehicle body.
而且，在根据本申请的实施例中，可在第二部3-2中设置旋转点70，使得当支撑件3发生向下旋转时，第二部3-2在旋转点70处发生断裂。具体地，相对于第二部3-2的其他部分，第二部3-2的旋转点70可设置为更易于发生断裂。因此，在车辆的后部发生撞击期间，第一部3-1可受力而向下旋转，同时第二部3-2也因此受力而在旋转点70处发生断裂，使得支撑件3在缓冲由于车辆撞击而产生的壁障能量的同时，吸收了壁障能量，从而使壁障能量无法传递至车身，进而防止车身的其他内部部件(例如，后围板)受到壁障能量的影响而发生较大的损坏，提高车辆的可修复性、为消费者节省成本。Moreover, in the embodiment according to the present application, a rotation point 70 may be provided in the second portion 3-2, so that when the support 3 is rotated downward, the second portion 3-2 is broken at the rotation point 70. Specifically, the rotation point 70 of the second portion 3-2 may be set to be more prone to fracture relative to other portions of the second portion 3-2. Therefore, during the collision of the rear part of the vehicle, the first part 3-1 can be rotated downward by force, and the second part 3-2 is also broken by the force at the rotation point 70, so that the support 3 is at While buffering the energy of the barrier caused by the impact of the vehicle, the energy of the barrier is absorbed, so that the energy of the barrier cannot be transmitted to the vehicle body, thereby preventing other internal parts of the vehicle body (for example, the rear panel) from being affected by the energy of the barrier. Major damage occurs, improving the repairability of the vehicle and saving costs for consumers.
优选地，如图1所示，第二部呈条形结构。Preferably, as shown in FIG. 1, the second portion has a strip-shaped structure.
根据本申请实施例的第二部3-2可设置为呈条形，这使得相应的制造模具结构简单、便于制造且节省成本。The second part 3-2 according to the embodiment of the present application may be provided in a strip shape, which makes the corresponding manufacturing mold structure simple, convenient to manufacture, and saves costs.

进一步地，如图1-5所示，基部、支撑件的第一部和第二部由塑料形成。Further, as shown in Figs. 1-5, the base portion, the first portion and the second portion of the support member are formed of plastic.
根据本申请的实施例，可使用塑料形成车辆后保险杆中支架。也就是说，基部2、支撑件3的第一部3-1和第二部3-2可由相同的塑料形成，其中塑料可例如为聚脂系塑料或聚丙烯系塑料，这使得后保险杠中支架的质量可被减轻，从而能够减少车辆的整体重量，因此能够实现轻量化且降低成本，经济性好，实用性强。优选地，通过使用聚丙烯加20％滑石粉(即，PP-TD20)来形成车辆后保险杆中支架。According to an embodiment of the present application, a vehicle rear bumper middle bracket may be formed using plastic. That is, the base portion 2, the first portion 3-1, and the second portion 3-2 of the support member 3 may be formed of the same plastic, where the plastic may be, for example, a polyester-based plastic or a polypropylene-based plastic, which makes the rear bumper The weight of the middle bracket can be reduced, so that the overall weight of the vehicle can be reduced, so that weight reduction and cost reduction can be achieved, the economy is good, and the practicability is strong. Preferably, the bracket in the rear bumper of the vehicle is formed by using polypropylene plus 20% talc (ie, PP-TD20).
