Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and in particular to a support structure and a plug-in hybrid vehicle. Background Technology

[0002] Plug-in hybrid electric vehicles (PHEVs) are becoming increasingly popular because they offer both short-distance battery range, saving on fuel costs, and long-distance range, unaffected by temperature and charging time. However, the collision protection of PHEVs is still in the exploratory stage. For example, currently, the structures used to install wiring harnesses and cooling pipes in PHEVs are mostly ordinary metal brackets. These brackets have low strength and can be completely destroyed in a collision, leading to wiring harness breakage, short circuits, and fires, or, due to their proximity to fuel lines, direct electrical sparks could cause a fire.

[0003] Therefore, there is an urgent need to design a wiring harness and cooling pipe support structure with collision protection function to reduce the possibility of the above situation occurring, or even avoid the above situation occurring. Summary of the Invention

Detailed Implementation

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] This embodiment provides a support structure 100 for mounting on the transmission 200 of a plug-in hybrid vehicle, such as... Figures 1-4 As shown, the support structure includes a main body 1, a first energy-absorbing component 2, and a second energy-absorbing component 3, wherein:

[0046] The main body 1 includes a collision part 11, a plurality of mounting parts 12 and a plurality of suspended legs 13. The plurality of mounting parts 12 and the plurality of suspended legs 13 are all disposed on the collision part 11. Each mounting part 12 is used to be disposed on the gearbox 200, and each suspended leg 13 is used to be suspended on the gearbox 200.

[0047] The first energy-absorbing member 2 and the second energy-absorbing member 3 are arranged at intervals along the circumference of the collision part 11 on the collision part 11. When the collision part 11 is subjected to external force, the first energy-absorbing member 2 and the second energy-absorbing member 3 can deform so that each suspended support leg 13 abuts against the gearbox 200.

[0048] In the support structure 100 provided in this embodiment, the collision part 11 of the main body 1 is provided with a plurality of mounting parts 12 for connecting with the gearbox 200 and a plurality of suspended legs 13 for being suspended on the gearbox 200. The collision part 11 is provided with first energy-absorbing members 2 and second energy-absorbing members 3 at circumferential intervals. When the support structure is provided on the gearbox 200, each mounting part 12 is connected to the gearbox 200 to fix the support structure on the gearbox 200. When subjected to external force (e.g., external collision), the first energy-absorbing members 2 and second energy-absorbing members 3 can deform and buffer a certain impact. Each suspended leg 13 can abut against the gearbox 200, thereby supporting the collision part 11, preventing the collision part 11 from being further compressed, and ensuring the strength and reliability of the support structure.

[0049] For example, the collision part 11 may include a collision plate, which may be provided with weight reduction holes and positioning holes 111; the support structure may be made of high-strength steel to make the support structure stronger.

[0050] In one optional implementation of the main body component 1, the main body component 1 includes multiple side plates 14 connected to the collision part 11. The collision part 11 and each side plate 14 cooperate to form a receiving space 110 for accommodating the plug 300. The receiving space 110 has a first opening and a second opening. The first opening is used for the plug 300 to enter and exit, and the second opening allows the plug 300 to connect to the gearbox 200. Obviously, the first opening and the second opening are connected.

[0051] The collision part 11 and each side plate 14 cooperate to form a receiving space 110 for accommodating the plug 300, so that the support structure also has the function of plug protection. At the same time, the above-mentioned multiple mounting parts 12 and multiple suspended legs 13 are all arranged circumferentially along the receiving space 110, so that each mounting part 12 can stably fix the support structure to the gearbox 200, and each suspended leg 13 can stably support the collision part 11 after the collision part 11 is subjected to external force.

[0052] For example, the main body 1 may include three side plates 14 connected in sequence, and the three side plates 14 cooperate with the collision part 11 to form a cuboid-shaped receiving space 110.

[0053] Furthermore, in an optional implementation, the first energy-absorbing element 2 and the second energy-absorbing element 3 are respectively disposed on a side plate 14, and the side plate 14 on which the first energy-absorbing element 2 is disposed is adjacent to the side plate 14 on which the second energy-absorbing element 3 is disposed.

[0054] Please continue to refer to Figure 1 Based on the above embodiments, in an optional implementation, the side plate 14 adjacent to the first opening is connected to the first energy-absorbing member 2. The first energy-absorbing member 2 includes a first connecting part 21, a first energy-absorbing part 22, and a second connecting part 23 connected in sequence, wherein:

[0055] The first connecting part 21 is connected to the corresponding side plate 14, and the second connecting part 23 is used to connect to the gearbox 200; the first energy-absorbing part 22 includes a first energy-absorbing body 221 and a second energy-absorbing body 222 connected to each other. The first energy-absorbing body 221 is connected to the first connecting part 21 and extends in a direction away from the collision part 11, and the distance between it and the corresponding side plate 14 gradually increases; the second energy-absorbing body 222 extends from the end of the first energy-absorbing body 221 away from the first connecting part 21 in a direction away from the collision part 11, and the distance between it and the corresponding side plate 14 gradually decreases; the second connecting part 23 is connected to the end of the second energy-absorbing body 222 away from the first energy-absorbing body 221.

[0056] For example, the first connecting part 21 can be a first connecting plate, which is attached to the corresponding side plate 14 and fixedly connected to the side plate 14; the second connecting part 23 can include a first connecting plate 231 and a second connecting plate 232 at an angle to each other, the first connecting plate 231 is connected to one end of the second connecting plate 232, and the second energy absorber 222 is connected to the end where the first connecting plate 231 and the second connecting plate 232 are connected.

[0057] Furthermore, in an optional implementation, the side plate 14 opposite to the first opening is connected to the second energy-absorbing member 3. The second energy-absorbing member 3 includes a third connecting part 31, a second energy-absorbing part 32, and a fourth connecting part 33 connected in sequence, wherein:

[0058] The third connecting part 31 is connected to the corresponding side plate 14, and the fourth connecting part 33 is used to connect to the gearbox 200; the second energy-absorbing part 32 includes a third energy-absorbing body 321 and a fourth energy-absorbing body 322 connected to each other. The third energy-absorbing body 321 is connected to the third connecting part 31 and is perpendicular to the third connecting part 31; the fourth energy-absorbing body 322 extends from the end of the third energy-absorbing body 321 away from the third connecting part 31 in a direction away from the collision part 11, and the distance between it and the corresponding side plate 14 gradually increases;

[0059] The fourth connecting part 33 is connected to the end of the fourth energy absorber 322 away from the third energy absorber 321 and extends in a direction away from the collision part 11, and the distance between the fourth connecting part 33 and the corresponding side plate 14 gradually increases.

[0060] The support structure is equipped with the aforementioned first energy-absorbing member 2 and second energy-absorbing member 3. When the collision part 11 is impacted by an external force, the first energy-absorbing member 2 and the second energy-absorbing member 3 collapse, deform, and bend, thereby buffering the impact on the collision part 11. At the same time, when the first energy-absorbing member 2 and the second energy-absorbing member 3 deform to a predetermined degree, each suspended support leg 13 can abut against the gearbox 200, thereby supporting the collision part 11, preventing the collision part 11 from being further compressed, and ensuring the strength and reliability of the support structure.

[0061] For example, after the collision part 11 is impacted, the two energy-absorbing welded structures, the first energy-absorbing member 2 and the second energy-absorbing member 3, collapse, deform, and bend due to the external impact. After the deformation exceeds 5mm, each suspended support leg 13 can abut against the gearbox 200. Figure 5 As shown, position A is the position of the corresponding energy-absorbing component before deformation, and position B is the position of the corresponding energy-absorbing component after deformation.

[0062] For example, the second connecting portion 23 and the fourth connecting portion 33 each form a mounting portion 12 as described above. For instance, a mounting hole is provided at the end of the first connecting plate away from the second connecting plate, and this mounting hole is the mounting portion 12 described above.

[0063] With the side plate 14 connected to the first energy-absorbing element 2 as the first side plate, in one optional implementation, such as... Figure 6 As shown, the first side plate includes a side plate body 142 connected to the collision part 11 and a second bent part 143 connected to the end of the side plate body 142 away from the collision part 11. A mounting part 12 is connected to the end of the second bent part 143 away from the side plate body. The first energy-absorbing member 2 is connected to the side plate body, and the connection between the first energy-absorbing member 2 and the side plate body is located between the collision part 11 and the second bent part 143.

[0064] For example, the mounting portion 12 connected to the second bend can be a long strip plate. The first end of the long strip plate in the length direction is connected to the second bend, and the second end in the length direction is used to connect to the gearbox 200. The portion between the first end and the second end has a notch formed at the edge so that when the collision portion 11 is impacted by an external force, the long strip plate can deform to buffer the impact on the support structure.

[0065] The side plate 14 connected to the first energy-absorbing member 2 is still the first side plate, and the side plate 14 opposite to the first side plate is the third side plate. The side plate 14 connected between the first side plate and the third side plate is the second side plate. In an optional implementation, the third side plate includes a first sub-plate 144 connected to the second side plate and a second sub-plate 145 located on the side of the first sub-plate 144 away from the second side plate. With the direction away from the collision part 11 as the first direction, the middle part of the second sub-plate 145 is recessed into the interior of the main body member 1 in the first direction, and a mounting part 12 is formed at the end of the second sub-plate 145 away from the collision part 11.

[0066] Furthermore, in an alternative implementation, the first sub-plate 144 has a suspended leg 13 formed at the end away from the collision part 11.

[0067] For example, the end of the first sub-plate 144 away from the collision part 11 may be folded outward to form a first flange, which is a suspended support leg 13.

[0068] Optionally, a cantilevered leg 13 is formed at the end of the second side plate away from the collision part 11.

[0069] For example, the end of the second side plate 14 away from the collision part 11 may be folded outward to form a second flange, which is a suspended support leg 13.

[0070] The support structure provided in this embodiment includes a collision part 11, a first energy-absorbing component 2, a second energy-absorbing component 3, and multiple side plates 14, which can integrate multiple mounting points for fixing multiple wire harnesses or pipes, etc. For example, the first energy-absorbing component 2 can be provided with at least one set of mounting points, the second energy-absorbing component 3 can be provided with at least one set of mounting points, and the first sub-plate 144 can be provided with at least one set of mounting points. Each set of mounting points includes one or more mounting points to facilitate the fixing of wire harnesses or pipes, etc.

[0071] The aforementioned installation points include, but are not limited to, mounting holes.

[0072] The support structure provided in this embodiment can integrate multiple installation points, including multiple valve bodies, wiring harnesses, and pipelines. This not only meets installation requirements but also effectively saves space, reduces the number of parts, and decreases the weight and cost of the support structure. At the same time, it can optimize the routing of wiring harnesses and pipelines, improve heat dissipation efficiency, effectively reduce the risk of overheating, and eliminate safety hazards.

[0073] Still taking the side plate 14 connected to the first energy-absorbing member 2 as the first side plate, the side plate 14 connected to the second energy-absorbing member 3 as the second side plate, and the other side plate 14 as the third side plate, in one optional implementation, such as Figure 7 As shown, both the first side plate and the third side plate have a first bend 141, and each first bend 141 is welded to the second side plate. That is, the support structure is self-welded into a box shape to form the aforementioned accommodating space 110.

[0074] The support structure is self-welded into a box shape, which increases the structural strength and provides better protection for the plug 300.

[0075] In one alternative implementation, the first energy-absorbing element 2 is welded to the main body element 1.

[0076] In one alternative implementation, the second energy-absorbing element 3 is welded to the main body element 1.

[0077] Simulation results show that the energy-absorbing component is welded to the main body 1, resulting in a stronger supporting structure and less deformation when subjected to external impacts.

[0078] This embodiment provides a plug-in hybrid vehicle including a plug 300, a gearbox 200 and the aforementioned support structure. The plug 300 is electrically connected to the gearbox 200 to supply power to the gearbox 200. The support structure is covered on the plug 300. Each mounting part 12 is disposed on the gearbox 200, and each suspended support leg 13 is suspended on the gearbox 200.

[0079] like Figure 8 As shown, in this embodiment of the plug-in hybrid vehicle, the plug 300 is electrically connected to the transmission 200. A support structure is mounted on the plug 300, each mounting part 12 is mounted on the transmission 200, and each suspended support leg 13 is suspended on the transmission 200. When the support structure is subjected to external force (e.g., an external collision), the first energy-absorbing member 2 and the second energy-absorbing member 3 can deform to buffer a certain impact. Each suspended support leg 13 can abut against the transmission 200, thereby supporting the collision part 11, preventing the collision part 11 from being further compressed, ensuring the strength and reliability of the support structure, and preventing the plug 300 from being damaged or leaking electricity due to collision damage.

[0080] For example, the plug 300 described above may be a plug that connects to the battery power line (i.e., the high-voltage harness 900).

[0081] In the plug-in hybrid vehicle provided in this embodiment, the battery and transmission can be connected by a straight wiring harness, which shortens the wiring harness transmission distance, reduces heat generation, and lowers transmission loss through straight power output.

[0082] For example, the car battery is centrally located, such as... Figures 8-11 As shown, the high-voltage wiring harness plug is located between the brake body and the gearbox. The support structure is made of high-strength steel, and the overall structure is self-welded into a box shape, covering the outside of the high-voltage wiring harness plug. The first water pump 500 and the second water pump 600 are installed on the outside. The support structure also provides mounting points for the water pump wiring harness 700 and the water pump pipeline 800. In the event of a collision, the two energy-absorbing components will collapse, deform, and bend due to the impact of external force. After the deformation exceeds 5mm, each suspended support foot will directly contact the gearbox. Relying on the box-shaped structure, the brake body is supported, so that the high-voltage wiring harness plug will not be damaged by the collision, preventing the danger of leakage.

[0083] In addition, the high-voltage harness plug can be protected by increasing the clearance distance, but this requires a lot of space; the position of the high-voltage harness plug can also be changed, but this requires a longer harness length.

[0084] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
