Description

Technical Field

[0001] The utility model belongs to the technical field of automobile parts, and more specifically relates to a ventilation cover plate mounting plate structure and a ventilation cover plate assembly. Background Art

[0002] The car vent cover is located in front of the car's front windshield and under the engine hood. The car vent cover mounting plate is a connector for mounting the car vent cover on the car body. The vent cover mounting plate is located in the rear of the cabin and in front of the front panel, and is used to increase the strength and rigidity of the entire front cabin. It connects the left and right wheel covers to provide balanced support for the left and right shock absorbers to prevent the two wheels from shaking when the car is turning or bumping. At the same time, it can bear a small part of the impact force of the road on the vehicle, improving the stability of the entire cabin.

[0003] At present, the ventilation cover mounting plate is generally welded to the brackets at the left and right front wheel housings respectively, and then the two ends of the ventilation cover mounting plate are fixed by three bracket bolts at the brackets on each side. However, the front power system of the car will generate large sound waves in the cabin. The left and right sides of the existing ventilation cover mounting plate are respectively connected to the left and right wheel housings, and the plate surface extends in the front-to-back direction, which cannot separate the front and back of the cabin. Therefore, the sound waves can be smoothly transmitted to the cab through the cabin, resulting in a large noise in the cab. In addition, since the ventilation cover mounting plate is relatively wide in the left-to-right direction and relatively small in the up-and-down direction, and the overall horizontally extending component is only fixed by the left and right sides, the vibration force generated by the vehicle during driving can easily cause the ventilation cover mounting plate to loosen, affecting the firmness of its installation.

[0028] Please also read Figure 1 to Figure 2 The ventilation cover mounting plate structure 10 and the ventilation cover assembly provided by the utility model are now described. The ventilation cover mounting plate structure 10 comprises a main board body 101, a first mounting portion 102 connected to the top of the main board body 101, and a second mounting portion 103 connected to the bottom of the main board body 101. The first mounting portion 102 is arranged at an angle with the main board body 101 and is connected to the ventilation cover. The second mounting portion 103 is connected to the cabin cross beam 20.

[0029] Compared with the prior art, the ventilation cover mounting plate structure 10 provided by the utility model is fixed in the upper and lower directions respectively, and the size of the main board body 101 in the left-right direction is larger than that in the upper and lower directions. Therefore, by fixing the top and bottom respectively, the stability and firmness of the connection can be increased, and the shaking of the main board body 101 caused by the vibration of the vehicle body can be avoided. In addition, the first mounting part 102 is connected to the ventilation cover plate, and the second mounting part 103 is connected to the cabin cross beam 20, so that the main board body 101 separates the cabin in the front-to-back direction, blocks the noise in the cabin from propagating to the cab, and reduces the noise decibels in the cab. The utility model improves the connection stability of the ventilation cover connecting plate structure, and by separating the cabin in the front-to-back direction, it effectively blocks the propagation path of the noise and prevents the noise from propagating to the cab.

[0030] It should be noted that the lower left of the main body 101 is the left front wheel cover shock-absorbing tower, and the lower right is the right front wheel cover tower. The lower part of the cabin cross beam 20 is connected with the heat insulation pad connecting plate 30, and the lower part of the heat insulation pad connecting plate 30 has a front panel assembly. Therefore, the cabin can be separated in the front and rear directions, blocking the noise propagation channel and reducing the noise decibels in the cab.

[0031] Specifically, the plate surface of the main plate body 101 extends in the up-down direction and the left-right direction.

[0032] In some embodiments, see Figure 1 A connecting flange is provided on the top of the main board body 101, and the connecting flange forms a first mounting portion 102, which overlaps with the ventilation cover plate.

[0033] In this embodiment, the connecting flange is located below the ventilation cover, the ventilation cover is placed on the top of the connecting flange, and the connecting flange is overlapped with the ventilation cover as a whole, thereby increasing the contact area and improving the stability and firmness of the connection. In addition, the connecting flange can also provide support for the ventilation cover.

[0034] Optionally, the connecting flange and the ventilation cover plate are welded or bonded, or screwed or clamped.

[0035] Optionally, the main board body 101 is provided with reinforcing ribs along the left-right direction to increase the strength of the main board body 101 and prevent the main board body 101 from deforming.

[0036] Optionally, the main board body 101 and the connecting flange are an integral component and can be processed by bending.

[0037] In some embodiments, see Figure 1 and Figure 5 The first mounting portion 102 is provided with a first mounting hole 1021 corresponding to the second mounting hole on the ventilation cover plate, and mounting pieces are inserted into the first mounting hole 1021 and the second mounting hole.

[0038] The first mounting hole 1021 can be formed by drilling or laser cutting when processing the connection flange, which is simple and convenient. The solution in this embodiment connects the first mounting part 102 with the ventilation cover plate by inserting the mounting piece into the first mounting hole 1021 and the second mounting hole, which is more secure than the clamping connection.

[0039] Optionally, the mounting member is a threaded member, and the first mounting hole 1021 and the second mounting hole are both threaded holes, and the mounting member is screwed into the first mounting hole 1021 and the second mounting hole. Alternatively, the mounting member includes a bolt and a nut, and the bolt is inserted into the first mounting hole 1021 and the second mounting hole, and the nut is screwed with the bolt to lock the first mounting portion 102 and the ventilation cover.

[0040] In some embodiments, see Figure 1 to Figure 2 The second mounting portion 103 includes a transition area 1033 and a fixing area 1032 which are arranged at an angle. The transition area 1033 is connected to the bottom of the main body 101 at an angle, and the fixing area 1032 is connected to the cabin cross beam 20 along the front-rear direction.

[0041] The transition area 1033 is at an angle to the main body 101, and the fixed area 1032 is at an angle to the transition area 1033. Compared with the solution in which the main body 101, the transition area 1033 and the fixed area 1032 are located in the same plane, this embodiment improves the overall strength and reduces the probability of deformation. The fixed area 1032 is connected to the cabin cross beam 20 in the front-to-back direction, which can further reduce the probability of noise propagating from the connection gap to the rear of the cabin compared to the connection method in the up-down direction, thereby improving the sound insulation effect.

[0042] In some embodiments, see Figure 1 The fixing area 1032 includes a plurality of fixing positions 1032 - 1 spaced apart along the left-right direction, and each fixing position 1032 - 1 is connected to the cabin cross beam 20 .

[0043] The solution in this embodiment reduces the weight of the entire ventilation cover mounting plate structure 10, which is conducive to achieving lightweight of the entire vehicle, and saves materials and reduces costs.

[0044] In some embodiments, see Figures 1 to 4 The fixing position 1032 - 1 is provided with a first fixing hole 1032 - 2 corresponding to the second fixing hole on the cabin cross beam 20 , and the fixing piece 104 is inserted into the first fixing hole 1032 - 2 and the second fixing hole.

[0045] The fixing member 104 is inserted into the first fixing hole 1032-2 and the second fixing hole, thereby locking the fixing position 1032-1 with the cabin cross beam 20. Compared with the bonding or welding method, this embodiment is more convenient to install, improves the installation efficiency, and avoids the problem of leaking welding during welding.

[0046] Optionally, the fixing member 104 is a threaded member, the first fixing hole 1032-2 and the second fixing hole are both threaded holes, and the fixing member 104 is threadedly connected to the first fixing hole 1032-2 and the second fixing hole. Or the fixing member 104 includes a bolt and a nut, the bolt is inserted into the first fixing hole 1032-2 and the second fixing hole, and the nut is threadedly connected to the bolt, so as to lock the fixing position 1032-1 with the cabin cross beam 20.

[0047] In some embodiments, see Figure 2 The bottom of the first fixing hole 1032-2 is connected to the outside, forming a semi-closed hole body in the up and down directions.

[0048] During installation, the fixing member 104 can be inserted into the second fixing hole first, and then the first fixing hole 1032-2 can be inserted from the top of the fixing member 104, and then the fixing member 104 can be locked to achieve the connection between the fixing position 1032-1 and the cabin cross beam 20. The solution in this embodiment does not need to correspond the first fixing hole 1032-2 to the second fixing hole, which improves the installation efficiency.

[0049] In some embodiments, see Figures 1 to 4 The second mounting portion 103 further includes a positioning area 1031 which is arranged at an angle to the main board body 101 , and the positioning area 1031 is arranged on the top of the cabin cross beam 20 .

[0050] The positioning area 1031 is set up on the top of the cabin beam 20 and positioned in the up and down directions, and the fixing area 1032 is fitted to the cabin in the front and back directions, so as to realize the positioning of the second mounting part 103 in the front and back and left and right directions respectively, avoiding relative displacement between the second mounting part 103 and the cabin beam 20 during the installation process, and ensuring the stability of the relative position during the installation process.

[0051] Optionally, the positioning area 1031 may be bonded or welded to the cabin cross beam 20 .

[0052] In some embodiments, see Figure 2 The positioning area 1031 is provided with a positioning hole 1031 - 1 , and the positioning hole 1031 - 1 is plugged and matched with the positioning piece 201 on the beam.

[0053] By plugging the positioning hole 1031-1 into the positioning piece 201, the second mounting portion 103 is limited not only in the up and down directions, but also in the left and right directions and the front and back directions. Therefore, when the fixing area 1032 and the cabin cross beam 20 are subsequently connected, there is no need to manually fix or lift the fixing area 1032, thereby reducing the installation labor, enabling single-person operation, and reducing labor costs.

[0054] Based on the same inventive concept, the utility model also provides a ventilation cover assembly. Figures 3 to 6 The ventilation cover assembly includes any one of the ventilation cover mounting plate structures 10 described above, and also includes a cabin cross beam 20 connected to the second mounting portion 103, and a ventilation cover connected to the first mounting portion 102, and a thermal insulation pad connecting plate 30 is connected below the cabin cross beam 20.

[0055] The ventilation cover assembly provided by the utility model adopts the ventilation cover mounting plate structure 10 mentioned above, which is fixed in the up and down directions respectively. The size of the main board body 101 in the left and right direction is larger than the size in the up and down direction. Therefore, by fixing the top and bottom respectively, the stability and firmness of the connection can be increased, and the shaking of the main board body 101 caused by the vibration of the vehicle body can be avoided. In addition, the first mounting part 102 is connected to the ventilation cover, and the second mounting part 103 is connected to the cabin cross beam 20, so that the main board body 101 separates the cabin in the front and back directions, blocks the noise in the cabin from propagating to the cab, and reduces the noise decibels in the cab. The utility model improves the connection stability of the ventilation cover connecting plate structure, and by separating the cabin in the front and back directions, it effectively blocks the propagation path of the noise and prevents the noise from propagating to the cab.

[0056] 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.
