DETAILED DESCRIPTION
[0029] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0030] It should be noted that the directions or positional relationships indicated by "front", "rear", "inside", "outside", "up" and "down" in this embodiment are based on the direction of the vehicle itself, where the head of the vehicle represents "front", the rear of the vehicle represents "rear", the top of the vehicle represents "up", and the bottom of the vehicle represents "down", the "inside" side refers to the side facing inside the cab, and the "outside" side refers to the side facing outside the cab.
[0031] In addition, the front and rear direction of the vehicle body defined in the embodiments of the present invention refers to the front and rear direction of the forward direction of the vehicle during driving, the left and right direction of the vehicle body defined refers to the left and right direction of the forward direction of the vehicle during driving, and the up and down direction of the vehicle body defined refers to the up and down direction of the forward direction of the vehicle during driving.
[0032] Please also read Figures 1 to 3 The engine compartment cover structure provided by the utility model is now described. The engine compartment cover structure comprises an engine compartment cover body 1 and a sealing plate 2. The engine compartment cover body 1 is provided with a maintenance opening 11; the sealing plate 2 is detachably arranged at the maintenance opening 11 and blocks the maintenance opening 11; the sealing plate 2 is also provided with a pressure relief structure 21.
[0033] The cabin cover body 1 is arranged on the engine compartment of the vehicle, and plays a protective role for the battery, collector and other components in the engine compartment of the vehicle. The cabin cover body 1 can be a certain plate in the cabin cover assembly. For example, in order to avoid the production difficulty caused by the cabin cover assembly being too large, the cabin cover assembly can be divided into a cabin front cover and a cabin center cover. The cabin cover body 1 in this embodiment can be a cabin front cover or a cabin center cover, as long as the opening position of the maintenance port 11 corresponds to the maintenance position of the components that need regular maintenance, such as the battery.
[0034] The battery needs regular maintenance. Before the maintenance operation, the cover plate 2 can be removed from the maintenance port 11 to expose the battery, thereby facilitating power connection and disconnection and maintenance operations on the battery without removing the cabin cover body 1.
[0035] The sealing plate 2 can be connected to the cabin cover body 1 by at least one detachable connection method such as plug-in, snap-on, screw-on, magnetic attraction, etc., and this embodiment does not limit the specific method of detachable connection. It should be noted that the outer structure of the sealing plate 2 is compatible with the structure of the maintenance port 11, so as to block the maintenance port 11 and prevent impurities from entering the engine compartment. In addition, after the sealing plate 2 is assembled, the upper surface of the sealing plate 2 is roughly flush with the upper surface of the cabin cover body 1.
[0036] The engine compartment cover structure provided by the utility model is suitable for pure electric new energy vehicles, where there is no engine in the cabin and the interior of the cabin is completely closed. The pressure relief structure 21 is arranged on the sealing plate 2. During the process of closing the cabin cover body 1, the pressure relief structure 21 plays a pressure relief role to avoid the pressure difference between the interior of the cabin and the outside, thereby ensuring that the cabin cover body 1 is closed smoothly.
[0037] Since the pressure relief structure 21 is arranged on the sealing plate 2, there is no need to destroy the overall structure of the cabin cover body 1, and it is sufficient to open the maintenance port 11 on the cabin cover body 1. The pressure relief structure 21 can be a hole structure directly formed on the sealing plate 2, or a grid structure with a hole structure or a gap. This embodiment does not limit the specific form of the pressure relief structure 21. In order to further prevent external impurities from entering the interior of the engine compartment through the pressure relief structure 21, the size of the hole or gap of the pressure relief structure 21 should be small, as long as the outside world can be connected to the interior of the engine compartment.
[0038] Compared with the prior art, the engine compartment cover plate structure provided by the utility model is provided with a maintenance opening 11 on the engine compartment cover plate main body 1, and a sealing plate 2 can be detachably connected at the maintenance opening 11, so that the maintenance components inside the engine compartment can be exposed by removing the sealing plate 2, so that the components inside the engine compartment can be repaired without removing the engine compartment cover plate main body 1, thereby improving the maintenance efficiency and avoiding damage to the engine compartment cover plate main body 1; in addition, a pressure relief structure 21 is provided on the sealing plate 2, and when the engine compartment cover plate structure is closed, the pressure relief structure 21 plays a pressure relief role, thereby ensuring that the engine compartment cover plate structure is smoothly closed.
[0039] In some embodiments, the pressure relief structure 21 may be configured as follows: Figure 1 and Figure 3 The structure shown, see Figure 1 and Figure 3 A pressure relief port is provided on the sealing plate 2, and the pressure relief structure 21 includes a grille arranged at the pressure relief port.
[0040] Specifically, the grille includes a plurality of grille bars arranged at intervals, and the two ends of each grille bar are respectively connected to the side walls of the pressure relief port; each grille bar is inclined toward the inside of the pressure relief port. In order to ensure that the plurality of grille bars are fixed and stable, at least two support bars are also arranged at the pressure relief port, and each support bar extends along the spacing direction of the plurality of grille bars; the support bars are provided with support inclined grooves corresponding to the plurality of grille bars one by one, and the grille bars are embedded in the corresponding support inclined grooves.
[0041] For every two adjacent grille bars, one side of the previous grille bar is located below the other grille bar, that is, there is an overlapping area in the projections of the two adjacent grille bars in the up and down directions of the vehicle body. In the up and down directions of the vehicle body, the previous grille bar can cover the next grille bar, and there is a gap between the previous grille bar and the next grille bar, which can prevent impurities from entering the engine compartment and connect the engine compartment with the outside world, avoiding pressure differences and ensuring that the engine compartment cover body 1 is closed smoothly.
[0042] In some embodiments, the detachable connection between the sealing plate 2 and the maintenance port 11 can be as follows: Figure 2 , Figure 3 and Figure 4 The structure shown, see Figure 2 , Figure 3 and Figure 4 The outer peripheral edge of the sealing plate 2 is provided with a transverse plug-in structure 22, and the transverse plug-in structure 22 is inserted into the bottom of the outer peripheral edge of the maintenance opening 11 along a first preset direction; the first preset direction is perpendicular to the up-down direction of the vehicle body.
[0043] During assembly, the sealing plate 2 is first tilted relative to the cabin cover body 1, so that the transverse plug-in structure 22 is inserted at the bottom of the outer peripheral edge of the maintenance opening 11, and then the other end of the sealing plate 2 is pressed downward to keep the upper surface of the sealing plate 2 flush with the upper surface of the cabin cover body 1. The transverse plug-in structure 22 abuts against the lower surface of the cabin cover body 1 and is limited in position with the cabin cover body 1 in the up and down direction of the vehicle body to fix the sealing plate 2.
[0044] The sealing plate 2 is fixed by plugging in the first preset direction, so that the assembly and disassembly operations of the sealing plate 2 are simple and convenient.
[0045] Preferably, the transverse plug-in structure 22 is an L-shaped plug-in block, the top end of which is connected to the outer peripheral edge of the cover plate 2, and the other end extends obliquely downward. In order to ensure smooth plugging along the first preset direction, a transverse avoidance opening 12 is provided at the portion of the outer peripheral edge of the maintenance opening 11 corresponding to the transverse plug-in structure 22, and the oblique extension end of the transverse plug-in structure 22 obliquely passes through the transverse avoidance opening 12, and the transverse portion of the transverse plug-in structure 22 abuts against the lower surface of the cabin cover plate body 1 to limit the position in the up and down direction of the vehicle body, such as Figure 4 shown.
[0046] It should be noted that the first preset direction is a fictitious direction, which is only used to illustrate the insertion direction of the transverse plug-in structure 22. It can be understood that the extension direction of the transverse part of the transverse plug-in structure 22 is the first plug-in direction.
[0047] In some embodiments, the detachable connection between the sealing plate 2 and the maintenance port 11 can also be achieved by: Figure 2 , Figure 3 and Figure 5 The structure shown, see Figure 2 , Figure 3 and Figure 5 A vertical plug-in hole 13 is provided on the cabin cover body 1, and a vertical plug-in structure 23 is provided on the outer peripheral edge of the sealing plate 2. The vertical plug-in structure 23 is elastically inserted into the plug-in hole 13 along the up and down direction of the vehicle body, and a part of the vertical plug-in structure 23 protrudes upward from the plug-in hole 13.
[0048] During assembly, the sealing plate 2 is first tilted relative to the cabin cover body 1 so that the transverse plug-in structure 22 is inserted into the bottom of the outer edge of the maintenance port 11, and then the other end of the sealing plate 2 is pressed downward so that the vertical plug-in structure 23 is inserted into the plug-in hole 13. The transverse plug-in structure 22 abuts against the lower surface of the cabin cover body 1, and the vertical plug-in structure 23 is elastically limited in the plug-in hole 13, so that the sealing plate 2 can be limited with the cabin cover body 1 in the up and down directions of the vehicle body, and can be limited with the cabin cover body 1 in the circumferential direction of the plug-in hole 13, so that the sealing plate 2 is fixed and stable.
[0049] In addition, the upper portion of the vertical plug-in structure 23 protrudes upward from the plug-in hole 13. When removing the cover plate 2, the upper portion of the vertical plug-in structure 23 can be pressed and pulled upward to disengage the vertical plug-in structure 23 from the plug-in hole 13, and then the cover plate 2 can be pulled back in the reverse direction along the first preset direction to disengage the cover plate 2 from the maintenance port 11.
[0050] By plugging the vertical plug-in structure 23 and the plug-in hole 13 in the up and down direction and elastically abutting against each other, the connection strength between the sealing plate 2 and the cabin cover body 1 can be improved, ensuring that the sealing plate 2 is stable after assembly and facilitating the disassembly operation of the sealing plate 2.
[0051] Preferably, see Figure 3 and Figure 5 The vertical plug-in structure 23 is a U-shaped plug-in block, one end of which is connected to the outer edge of the sealing plate 2, and the other end is a free end, and a protrusion is provided on the outer wall corresponding to the free end. After the U-shaped plug-in block is inserted into the plug-in hole 13, the upper surface of the protrusion abuts against the outer bottom surface of the plug-in hole 13.
[0052] Preferably, see Figure 3 The horizontal plug-in structure 22 and the vertical plug-in structure 23 are spaced apart and distributed along the first preset direction.
[0053] Since the transverse plug-in structure 22 is inserted along the first preset direction, and the transverse plug-in structure 22 and the vertical plug-in structure 23 are spaced apart along the first preset direction, after the sealing plate 2 is disassembled to disengage the vertical plug-in structure 23 from the plug-in hole 13, the transverse plug-in structure 22 is lifted up obliquely as a whole, and is obliquely abutted against the lower surface of the cabin cover body 1 as a whole, thereby ensuring that the transverse plug-in structure 22 is evenly stressed, and also facilitating the reverse pulling back of the sealing plate 2 along the first preset direction.
[0054] In order to improve the aesthetic performance of the sealing plate 2, the sealing plate 2 is preferably a rectangular plate, the horizontal plug-in structure 22 is arranged on the edge of the long side (or short side) of one side of the rectangular plate, and the vertical plug-in structure 23 is arranged on the edge of the long side (or short side) of the other side of the rectangular plate.
[0055] In some embodiments, the detachable connection between the sealing plate 2 and the maintenance port 11 can also be achieved by: Figure 2 , Figure 3 and Figure 6 The structure shown, see Figure 2 , Figure 3 and Figure 6 Two groups of clip structures 24 are also provided on the outer peripheral edge of the sealing plate 2. The two groups of clip structures 24 are spaced apart along the second preset direction, and the two groups of clip structures 24 are respectively clipped on the outer peripheral edge of the maintenance opening 11 along the up-down direction of the vehicle body; wherein the second preset direction is perpendicular to the up-down direction of the vehicle body and also perpendicular to the first preset direction.
[0056] It should be noted that the first preset direction is a fictitious direction, which is only used to illustrate the spacing direction of the two groups of clamping structures 24. In addition, the two groups of clamping structures 24 can also be symmetrically distributed along the first preset direction.
[0057] If the sealing plate 2 is a rectangular plate, the two groups of snap-fit structures 24, the transverse plug-in structure 22, and the vertical plug-in structure 23 each occupy one side edge of the rectangular plate, and the two groups of snap-fit structures 24 are arranged oppositely, and the transverse plug-in structure 22 and the vertical plug-in structure 23 are arranged oppositely.
[0058] Both groups of snap-in structures 24 abut against the outer peripheral edge of the lower surface of the maintenance opening 11 along the direction above the vehicle body. Specifically, during assembly, the sealing plate 2 is first tilted relative to the cabin cover body 1, so that the transverse plug-in structure 22 is inserted at the bottom of the outer peripheral edge of the maintenance opening 11, and then the other end of the sealing plate 2 is pressed downward to insert the vertical plug-in structure 23 into the plug-in hole 13, and at the same time, the two groups of snap-in structures 24 are squeezed between the maintenance opening 11 along the second preset direction, and the two groups of snap-in structures 24 also abut against the lower surface of the cabin cover body 1 along the up-down direction of the vehicle body; in addition, the transverse plug-in structure 22 also abuts against the lower surface of the cabin cover body 1, so that the sealing plate 2 can be limited with the cabin cover body 1 in the up-down direction of the vehicle body, and can be limited with the cabin cover body 1 in the circumferential direction of the plug-in hole 13, and can also be squeezed and limited in the second preset direction, so that the sealing plate 2 is fixed and stable.
[0059] When removing the sealing plate 2, by pressing and pulling upward the upper part of the vertical plug-in structure 23, the vertical plug-in structure 23 can be disengaged from the plug-in hole 13, while driving the two sets of snap-on structures 24 to disengage from the maintenance port 11, and then the sealing plate 2 can be pulled back in the opposite direction along the first preset direction to disengage the sealing plate 2 from the maintenance port 11.
[0060] Preferably, the clamping structure 24 is a clamping block with a clamping hook, and its top end is connected to the outer edge of the cover plate 2. In order to ensure smooth insertion along the up-down direction of the vehicle body, a vertical avoidance opening 14 is provided at the position of the outer edge of the maintenance opening 11 corresponding to the clamping structure 24, and the clamping structure 24 passes downward through the vertical avoidance opening 14, and the clamping hook of the clamping structure 24 abuts against the lower surface of the cabin cover plate body 1 to limit the position in the up-down direction of the vehicle body, such as Figure 6 shown.
[0061] In some embodiments, the cabin cover body 1 and the sealing plate 2 may also be provided with Figure 2 and Figure 3 The structure shown, see Figure 2 and Figure 3 An annular sink 15 is provided on the outer peripheral wall of the maintenance opening 11 , and an annular flange 25 protruding downward is provided on the outer peripheral edge of the sealing plate 2 , and the annular flange 25 is mounted on the annular sink 15 .
[0062] The annular flange 25 abuts against the annular sink 15 in the up and down directions of the vehicle body. After the sealing plate 2 is assembled, the annular sink 15 plays a role in supporting the sealing plate 2. On the one hand, it can increase the connection stability performance of the horizontal plug-in structure 22, the vertical plug-in structure 23 and the clamping structure 24 with the cabin cover body 1 respectively. On the other hand, it can also ensure the surface difference clearance requirement between the sealing plate 2 and the maintenance port 11.
[0063] Preferably, the bottom surface of the annular flange 25 is further provided with a plurality of support ribs 26, and each support rib 26 is respectively in contact with the upper surface of the annular sink 15. The plurality of support ribs 26 are distributed at intervals along the circumferential direction.
[0064] Each support rib 26 protrudes downward from the annular flange 25. Figure 7 As shown, the annular flange 25 is in contact with the upper surface of the annular sink 15 through a plurality of supporting ribs 26 to ensure that the surface difference between the sealing plate 2 and the cabin cover body 1 is uniform after assembly.
[0065] Preferably, the annular sink 15 is provided with a plurality of upwardly protruding limiting ribs 16. The plurality of limiting ribs 16 are also distributed at intervals along the circumferential direction. The distances between each limiting rib 16 and the outer peripheral surface of the maintenance opening 11 are equal.
[0066] Each limiting rib 16 protrudes upward from the annular sink 15 to ensure that the gap between the sealing plate 2 and the outer peripheral surface of the maintenance opening 11 is uniform after assembly.
[0067] Based on the same inventive concept, an embodiment of the present application also provides a vehicle, comprising the above-mentioned engine compartment cover structure.
[0068] The vehicle provided by the utility model adopts the above-mentioned engine compartment cover structure, which can reduce the maintenance time of components in the engine compartment, avoid damage to the engine compartment cover body 1, and also has a pressure relief function to ensure that the engine compartment cover structure is smoothly closed.
[0069] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
