Description

Technical Field

[0001] This disclosure relates to the field of vehicle body structure technology, and more specifically, to a rear floor reinforcement structure for a vehicle body and a vehicle. Background Technology

[0002] The rear floor of a typical vehicle (which may contain seat and seatbelt mounting points) is a horizontal sheet metal part, connected to the vertical rear bulkhead by weld points. Below the rear floor is a rear floor crossbeam, which is connected to the rear floor support frame by weld points, forming a T-shaped structure. The lower end of the rear floor support frame is connected to the vehicle's longitudinal beams by weld points. The rear floor crossbeam is designed with a certain height and joint cross-sectional shape primarily to improve the strength and rigidity of the rear of the floor. However, its height is limited by the vehicle's height and engine placement space, and the T-shaped connection to the rear floor support frame results in relatively low strength and rigidity at the rear of the vehicle floor. Utility Model Content

[0003] The purpose of this disclosure is to provide a rear floor reinforcement structure and vehicle that can solve the aforementioned technical problems.

[0004] To achieve the above objectives, this disclosure provides a rear floor reinforcement structure for a vehicle body, comprising: a support body for obliquely disposed between a rear floor crossbeam and a rear floor support frame to form a triangular support structure; the support body includes a supporting section, a transition section, and a supporting section; the supporting section extends in the same direction as the rear floor crossbeam to connect with the bottom of the rear floor crossbeam; the supporting section is disposed below the supporting section for connecting with the side of the rear floor support frame; and the transition section is obliquely disposed longitudinally between the supporting section and the supporting section to connect the supporting section and the supporting section.

[0005] Optionally, one end of the support section is inclined toward the rear floor beam to connect with the transition section, and the other end is perpendicular to the rear floor support frame.

[0006] Optionally, the support body includes a connecting plate and a reinforcing plate, the reinforcing plate being disposed on the side of the connecting plate and extending along the height direction.

[0007] Optionally, the supporting section portion has reinforcing plates extending in the same direction on both sides of the connecting plate.

[0008] Optionally, one side of the connecting plate of the transition section and the supporting section is cut with an avoidance groove, and the connecting plate at that location is provided with a reinforcing plate on the side away from the avoidance groove. The connecting plate of the supporting section is used to connect with the bottom of the rear floor beam, and the reinforcing plate of the supporting section is used to connect with the side of the rear floor beam.

[0018] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0019] In this disclosure, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" generally refer to the upper, lower, top, and bottom of the corresponding component in the direction of gravity when in use, while "inner" and "outer" refer to the inner and outer contours relative to the component or structure itself. Furthermore, in the description with reference to the accompanying drawings, the same reference numerals in different drawings denote the same elements.

[0020] like Figure 1 As shown, this disclosure provides a rear floor reinforcement structure for a vehicle body, including: a support body 3, which is obliquely disposed between a rear floor crossbeam 1 and a rear floor support frame 2 to form a triangular support structure. The support body 3 includes a supporting section 31, a transition section 32, and a supporting section 33. The supporting section 31 extends in the same direction as the rear floor crossbeam 1 to connect with the bottom of the rear floor crossbeam 1. The supporting section 33 is disposed below the supporting section 31 to connect with the side of the rear floor support frame 2. The transition section 32 is obliquely disposed longitudinally and disposed between the supporting section 31 and the supporting section 33 to connect the supporting section 31 and the supporting section 33.

[0021] Through the above technical solution, the support body 3 includes a supporting section 31, a transition section 32 and a supporting section 33. The supporting section 31 extends in the same direction as the rear floor beam 1 to increase the contact area with the rear floor beam 1 and increase the support. The supporting section 33 is connected to the rear floor support frame 2. The transition section 32 is set at an incline along the longitudinal direction to connect the supporting section 31 and the supporting section 33, so that the support body 3, the rear floor beam 1 and the rear floor support frame 2 form a triangular support structure to increase the strength and rigidity of the rear of the base plate.

[0022] As an optional implementation method, such as Figure 1 and Figure 3 As shown, one end of the support section 33 is inclined toward the rear floor beam 1 to connect with the transition section 32, and the other end is perpendicular to the rear floor support frame 2. The inclined arrangement of the support section 33 to connect with the transition section 32 can reduce the space occupied on the side of the support body 3 and reduce the lateral extension. The perpendicular arrangement of the other end of the support section 33 to the rear floor support frame 2 can enhance the connection strength and facilitate welding.

[0023] As an optional implementation method, such as Figure 3-5As shown, the support body 3 includes a connecting plate 34 and a reinforcing plate 35. The reinforcing plate 35 is disposed on the side of the connecting plate 34 and extends along the height direction. The reinforcing plate 35 can increase the vertical stiffness of the support body 3. The reinforcing plate 35 can extend upward or downward. For example, in this disclosure, the reinforcing plate 35 is provided to extend upward.

[0024] Optionally, such as Figure 4-5 As shown, the connecting plate 34 of the support section 33 is provided with reinforcing plates 35 extending in the same direction on both sides, and the reinforcing plates 35 on both sides are provided to increase the vertical stiffness of the support section 33.

[0025] Among them, such as Figure 1-5 As shown, one side of the connecting plate 34 of the transition section 32 and the supporting section 31 has a clearance groove 36, and the side of the connecting plate 34 away from the clearance groove 36 is provided with a reinforcing plate 35. The connecting plate 34 of the supporting section 31 is used to connect with the bottom of the rear floor beam 1, and the reinforcing plate 35 of the supporting section 31 is used to connect with the side of the rear floor beam 1. Because the engine is installed under the rear floor beam 1, the clearance groove 36 is to avoid the engine and avoid affecting the engine's motion envelope. At the same time, because the rear floor beam 1 is wide, if the reinforcing plates 35 are provided on both sides, the connecting plate 34 cannot connect with the bottom of the rear floor beam 1. Therefore, the reinforcing plate 35 is only provided on one side of the connecting plate 34. In order to make the connection more secure, the supporting section 31 is welded to the rear floor beam 1.

[0026] Optionally, such as Figure 2 As shown, the transition section 32 is inclined in the horizontal direction away from the avoidance groove 36, also to avoid the engine under the rear floor beam 1 and make room for the engine's motion envelope.

[0027] In addition, such as Figure 3-5 As shown, the end of the support section 33 that is connected to the rear floor support frame 2 is provided with a flange 4 parallel to the rear floor support frame 2. The flange 4 is used to connect to the side of the rear floor support frame 2 to increase the connection area. For example, there are three flanges 4. The reinforcing plate 35 and the connecting plate 34 are both connected with flanges 4. The support section 33 is welded to the rear floor support frame 2 through the flanges 4.

[0028] As an optional implementation method, such as Figure 3-5 As shown, the support body 3 is constructed as a one-piece stamped part. Stamping is convenient and quick to process, requires no welding, and facilitates the fabrication of the flange 4. Of course, in other embodiments, the support body 3 can also be constructed as a tube.

[0029] As an optional implementation method, such as Figure 4As shown, the support body 3 is provided with welding positioning holes 6 and projection welding stations 5. The welding positioning holes 6 are used to position the support body 3 by passing the positioning pin of the welding fixture through the welding positioning holes 6 during welding of the support body 3. In order to ensure accurate positioning, at least two welding positioning holes 6 are provided. The projection welding station 5 is convenient for subsequent welding of the end face projection welding bolts to install heat insulation cotton to insulate the engine below.

[0030] This disclosure also provides a vehicle including: the aforementioned rear floor reinforcement structure, which forms a triangular support structure with the rear floor crossbeam 1 and the rear floor support frame 2 by providing a support body 3, thereby increasing the strength and rigidity of the rear floor.

[0031] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0032] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0033] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
