It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the invention described herein may be implemented in sequences other than those illustrated or otherwise described herein.

Referring to fig. 1 and 2, an embodiment of the present invention provides a luggage floor support structure including a sub-frame 1 and a support beam 2, the sub-frame 1 being adapted to be connected to a body frame 200 of a vehicle, one end of the support beam 2 in a vertical direction of the vehicle being adapted to be connected to a luggage floor 100 of the vehicle, and the other end of the support beam 2 in the vertical direction of the vehicle being adapted to be connected to the sub-frame 1.

The vertical direction of the vehicle may be referred to as the Z-axis direction in fig. 1 and 2, or simply as the vertical direction, and the front-rear direction of the vehicle may be referred to as the X-axis direction in fig. 1 and 2, simply as the front-rear direction, and the left-right direction of the vehicle may be referred to as the Y-axis direction in fig. 1 and 2, simply as the left-right direction.

Specifically, the sub-frame 1 is intended to be fitted under the luggage floor 100, and the luggage floor 100 is located at the rear of the vehicle body, so the sub-frame 1 in the present embodiment is also a rear sub-frame of the vehicle. The body frame 200 generally includes a body side member 210 and a body cross member 220, and the front end of the sub-frame 1 is generally connected to the body cross member 220 of the body frame 200, and the rear end of the sub-frame 1 is generally connected to the body side member 210 of the body frame 200. The support beam 2 is usually arranged vertically or inclined with respect to the vertical, for example, an example of an inclined arrangement of the support beam 2 is given in fig. 1, in which case the support beam 2 corresponds to a diagonal bracing structure. The upper end of the support beam 2 is typically bolted to the luggage floor 100, and the lower end of the support beam 2 is typically welded to the rear end of the subframe 1, so that the rear end of the subframe 1 is also connected to the luggage floor 100, for example, by the support beam 2.

The luggage floor support structure in this embodiment can realize the mounting and fixing of the sub-frame 1 by connecting the sub-frame 1 with the vehicle body frame 200. Meanwhile, by providing the support beam 2 and connecting, for example, the upper end of the support beam 2 to the luggage floor 100, the lower end of the support beam 2 is connected to the sub-frame 1, for example, so that a vertical connection is formed between the sub-frame 1 and the luggage floor 100 through the support beam 2. In this way, the load borne by the luggage floor 100 can be transmitted to the sub-frame 1 via the support beam 2, so that a part of the load can be shared by the sub-frame 1, and the load-bearing capacity of the luggage floor 100 can be improved. Moreover, the support beam 2 can reinforce and support the luggage floor 100 in the vertical direction, thereby enhancing the vertical rigidity of the luggage floor 100 and the stability and rigidity of the whole luggage, and further improving the carrying capacity of the luggage floor 100. In addition, compared with the prior art that the bottom of the luggage compartment floor 100 is added with the supporting beam to improve the bearing performance, the auxiliary frame 1 and the luggage compartment floor 100 are connected by the supporting beam 2 to improve the bearing performance of the luggage compartment floor 100, so that the luggage compartment floor 100 has the advantages of simple structure, easiness in processing, manufacturing and assembling, material saving, light weight and low production cost; moreover, the support beam 2 can replace the existing support beams, which is equivalent to reducing the number of the support beams, thereby further reducing the cost and the weight of the whole vehicle.

Optionally, as shown in conjunction with fig. 1 and 2, the luggage compartment floor support structure further includes a floor reinforcement beam 3, where the floor reinforcement beam 3 extends in the left-right direction of the vehicle and is configured to be spaced from a body longitudinal beam 210 of the body frame 200, and an end of the support beam 2 remote from the subframe 1 is configured to be connected to a lower end of the luggage compartment floor 100 through the floor reinforcement beam 3.

Specifically, the floor reinforcement beam 3 is generally fixed to the bottom of the luggage floor 100 by welding, and the upper end of the support beam 2 is not directly connected to the luggage floor 100, but is connected to the luggage floor 100 through the floor reinforcement beam 3, and the support beam 2 is generally connected to the floor reinforcement beam 3 by bolts, so as to facilitate assembly and disassembly. The body frame 200 generally includes two body stringers 210, i.e., one on each of the left and right sides, and the spacing between the floor reinforcement beam 3 and the body stringers 210 means that there is a space between the left end of the floor reinforcement beam 3 and the left body stringer 210, and there is a space between the right end of the floor reinforcement beam 3 and the right body stringer 210. That is, the length of the floor reinforcement beam 3 (i.e., the dimension of the floor reinforcement beam 3 in the left-right direction) is smaller than the distance between the left and right side members 210.

In this embodiment, the floor reinforcement beam 3 may be disposed at the bottom of the luggage floor 100, and one end of the support beam 2 far from the subframe 1 may be connected to the floor reinforcement beam 3, so that the weight and pressure of the luggage may be evenly dispersed to the entire luggage floor 100 by using the floor reinforcement beam 3, so that the concentrated load in certain specific areas may be reduced, and further the bearing capacity of the luggage floor 100 may be improved, and the concentration degree of the vertical stress may be reduced.

Alternatively, as shown in fig. 1 and 2, the sub-frame 1 includes a frame rail 12 and a frame cross member 11, the frame cross member 11 is disposed to extend in the left-right direction of the vehicle, the frame rail 12 is disposed to extend in the front-rear direction of the vehicle, both ends of the frame cross member 11 are respectively connected to a vehicle body rail 210, the support beam 2 is connected to the frame cross member 11, one end of the frame rail 12 in the front-rear direction of the vehicle is connected to a vehicle body cross member 220, the other end is connected to the frame cross member 11, and the frame cross member 11 is arranged to be disposed on a side of the vehicle body cross member 220 facing the rear of the vehicle.

In this embodiment, the number of frame rails 12 may be one or plural, and in practical applications, it is generally preferable to provide two frame rails 12, as shown in fig. 1. The frame rail 11 is located on the rear side of the body rail 220, the front end of the frame rail 12 is directly connected to the body rail 220, and the rear end of the frame rail 12 is connected to the frame rail 11. Since the frame rail 11 is connected to the rear end of the frame rail 12, the frame rail 11 is also the rear rail of the subframe 1. That is, the main structure of the subframe 1 is constituted by only one rear cross member and two side members. Compared with the auxiliary frame structure formed by two cross beams and two longitudinal beams in the prior art, the auxiliary frame structure omits a front cross beam, can reduce production cost, lighten the weight of the whole vehicle to a large extent and is convenient for realizing lightweight design.

Alternatively, as shown in conjunction with fig. 1 and 2, two support beams 2 are provided, the two support beams 2 are oppositely disposed on the sub-frame 1 in the left-right direction of the vehicle, and one ends of the two support beams 2 remote from the sub-frame 1 are respectively connected to both ends of the floor reinforcement beam 3 in the left-right direction of the vehicle.

In the present embodiment, two support beams 2 are disposed on the rear cross member of the subframe 1 in a generally opposed manner, and the upper ends of the two support beams 2 are connected to the left and right ends of the floor reinforcement beam 3, respectively. In this way, the two support beams 2 are adopted to support the luggage floor 100, so that the support effect can be improved, the weight of the bottom of the luggage floor can be better dispersed, the pressure of the bottom cross beams such as the car body cross beam 220 of the bottom of the luggage floor 100 is reduced, the even load distribution born by the luggage floor 100 is ensured, and the support capacity of the luggage floor 100 can be further improved.

Alternatively, as shown in connection with fig. 1, the distance between the two support beams 2 increases from top to bottom.

Specifically, the lower ends of the support beams 2 are disposed obliquely downward and away from the other support beam 2, that is, the distance between the upper ends of the two support beams 2 is small, the distance between the lower ends is large, and the distance between the two support beams 2 gradually increases from top to bottom. This makes two supporting beams 2, floor stiffening beam 3 and the rear cross beam of sub vehicle frame 1 constitute trapezium structure, and this trapezium structure can be isosceles trapezoid, and at this moment, two supporting beams 2 are bilateral symmetry setting, and this trapezium structure also can be right trapezoid, and at this moment, one of two supporting beams 2 is vertical setting, and another is the slope setting, and this trapezium structure still can be except isosceles trapezoid and right trapezoid's ordinary trapezium, and at this moment, two supporting beams 2 all slope setting, but inclination is not the same.

In this embodiment, the distance between the two support beams 2 is set to be increased from top to bottom, so that the two support beams 2, the floor reinforcement beam 3 and the rear cross beam of the subframe 1 together form a trapezoid structure, for example, and the trapezoid structure can improve the rigidity of the luggage floor 100 to a greater extent, thereby improving the carrying capacity and stability of the luggage floor 100.

Alternatively, as shown in connection with fig. 3, the support beam 2 includes a first beam body 21, a second beam body 22 and a third beam body 23 which are connected in sequence and enclose a cavity beam structure, the first beam body 21 and the third beam body 23 are disposed opposite to each other and located on the same side of the second beam body 22, and one ends of the first beam body 21, the second beam body 22 and the third beam body 23 in the up-down direction of the vehicle are respectively connected to the floor reinforcement beam 3, and the other ends are respectively connected to the subframe 1.

In this embodiment, the supporting beams 2 are of an integral structure, and may be integrally formed or connected by welding, and the first beam 21, the second beam 22 and the third beam 23 of the supporting beam 2 enclose a cavity beam structure with a substantially C-shaped cross section, where the cross section of the cavity beam structure refers to the cross section of the cavity beam structure in the direction perpendicular to the extending direction thereof, and the opening of the C-shape may face the other supporting beam 2 or deviate from the other supporting beam 2, that is, the C-shaped openings of the two supporting beams 2 may be disposed opposite or facing away from each other. Thus, by designing the support beam 2 as a cavity beam structure surrounded by the first beam body 21, the second beam body 22 and the third beam body 23 and having a substantially C-shaped cross section, not only can the structure of the support beam 2 be simplified, but also the support beam 2 can have a certain support rigidity while having a lighter weight.

Optionally, as shown in connection with fig. 3, the support beam 2 further includes a fourth beam 24, the cavity beam structure has a first end and a second end which are disposed opposite to each other and are open, the subframe 1 is blocked at the first end of the cavity beam structure, the fourth beam 24 is blocked at the second end of the cavity beam structure, and one end of the first beam 21, the second beam 22 and the third beam 23, which is far from the subframe 1, is connected to the floor reinforcement beam 3 through the fourth beam 24.

In this embodiment, the first end and the second end of the cavity beam structure are respectively the upper end and the lower end of the cavity beam structure, and the upper end and the lower end of the cavity beam structure are in an open shape, wherein the upper end of the cavity beam structure is connected to the fourth beam 24, the lower end of the cavity beam structure is connected to the rear cross beam of the subframe 1, meanwhile, the fourth beam 24 seals the opening of the upper end of the cavity beam structure, the rear cross beam of the subframe 1 seals the opening of the lower end of the cavity beam structure, and furthermore, the upper ends of the first beam 21, the second beam 22 and the third beam 23 are respectively connected to the lower end of the fourth beam 24, and the upper end of the fourth beam 24 is connected to the lower end of the floor reinforcement beam 3. In this way, by arranging the fourth beam 24 and plugging the fourth beam 24 at the second end of the cavity beam structure surrounded by the first beam 21, the second beam 22 and the third beam 23, that is, the upper end of the cavity beam structure, the fourth beam 4 seals the upper end of the cavity beam structure in an open state, so that on one hand, the rigidity and the structural stability of the support beam 2 can be further increased by using the fourth beam 24, and on the other hand, the contact area between the support beam 2 and the floor reinforcement beam 3 can be increased by using the fourth beam 24, and the connection firmness of the support beam 2 and the floor reinforcement beam 3 can be ensured.

Optionally, as shown in fig. 3 and 4, the fourth beam 24 is provided with a mounting hole 241, a fastener 36 is pre-embedded on a side of the floor reinforcing beam 3 facing away from the luggage floor 100, and the fastener 36 is coaxially disposed with the mounting hole 241.

In this embodiment, the fastener 36 is usually a bolt, and the fastener 36 is pre-embedded in the bottom of the floor reinforcement beam 3, that is, on the side of the floor reinforcement beam 3 facing away from the luggage compartment floor 100, by adopting a welding manner, and the mounting hole 241 is provided on the fourth beam body 24 of the support beam 2, so that when assembling, the fastener 36 can pass through the mounting hole 241 of the support beam 2 and be screwed by a nut, thereby fixing the support beam 2 on the floor reinforcement beam 3, so as to realize vertical connection between the subframe 1 and the luggage compartment floor 100, and the assembly and disassembly efficiency is high, and the maintenance and the replacement are convenient.

Optionally, as shown in fig. 4, the floor reinforcement beam 3 includes a first plate 31, a second plate 32, a third plate 33, a fourth plate 34, and a fifth plate 35, where the first plate 31 is disposed at a right angle or an obtuse angle to the second plate 32, the second plate 32 is disposed at a right angle or an obtuse angle to the third plate 33, the third plate 33 is disposed at a right angle or an obtuse angle to the fourth plate 34, the fourth plate 34 is disposed at a right angle or an obtuse angle to the fifth plate 35, and the first plate 31 and the fifth plate 35 are located above the third plate 33.

In this embodiment, the floor reinforcement beam 3 is an integral structure, which may be integrally formed, or may be integrally connected by means of splice welding, where the floor reinforcement beam 3 includes five plate bodies, namely, a first plate body 31, a second plate body 32, a third plate body 33, a fourth plate body 34 and a fifth plate body 35, and the first plate body 31 and the fifth plate body 35 are located above the third plate body 33, and the second plate body 32 and the fourth plate body 34 are oppositely disposed, and two adjacent plate bodies are disposed at right angles or obtuse angles.

In this embodiment, the shock insulation pad 4 is generally made of rubber material, and is used for buffering the impact of the luggage in the luggage compartment caused by jolt and vibration. Since the baggage in the trunk may generate jolts and vibrations more or less during the running of the vehicle, the impact of the baggage during jolts and vibrations may be transferred to the support beam 2 through the trunk floor 100 and the floor reinforcement beam 3, and the support beam 2 may have a certain support rigidity, so that fatigue cracks may be easily caused to the support beam 2 and the trunk floor 100 and the baggage under the action of jolts and vibrations for a long time. Therefore, in this embodiment, the shock insulation pad 4 is additionally arranged between the support beam 2 and the floor reinforcement beam 3, so that jolt and vibration generated in the transportation process of the luggage in the vehicle can be absorbed and buffered by using the shock insulation pad 4, and the impact on the luggage compartment floor 100 during jolt and vibration of the luggage can be reduced, so that the risk of fatigue cracking of the luggage compartment floor 100, the luggage and the support beam 2 can be reduced, the damage caused by vibration can be improved, and the stability and durability of the whole luggage compartment can be further improved.
