Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, 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.

[0022] Figure 1 A schematic diagram of a sealed structure for the front compartment of an electric vehicle is shown. Figure 1 As shown, a sealed structure for the front compartment of an electric vehicle includes a decorative cover 2 and a storage box 3. The storage box 3 is connected to the decorative cover 2 via a buckle 21. Figure 2 A schematic diagram showing the connection of the decorative cover 2, storage box 3, and sealing element 4 is provided. Figure 2 As shown, a sealing element 4 is fitted onto the storage box 3, and a water-blocking element 5 is provided on the part of the sealing element 4 near the decorative cover 2. The end of the water-blocking element 5 away from the decorative cover 2 overlaps with the decorative cover 2. Figure 3 A schematic diagram of the hood 1 is shown, as follows. Figure 3 As shown, the end of the seal 4 away from the storage box 3 contacts the organic cover 1.

[0023] The sealing structure of the front compartment of the electric vehicle, through the sealing element 4 fitting with the hood 1 and the water baffle 5 overlapping with the decorative cover 2, can form a complete sealing performance. It can not only effectively solve the problem of water and dust entering the front compartment storage box 3, but also perform excellently in functions such as water blocking, water guiding and drainage.

[0024] Specifically, after the hood 1 comes into contact with the seal 4, a large amount of water entering from the windshield side will be drained through the water leakage hole 22 of the decorative cover 2 to the lower part of the front compartment and drip out of the car due to the obstruction of the seal 4. Water entering from both sides of the car will be blocked by the water baffle 5. If some water enters the water channel 31 of the storage box 3 through the water baffle 5, it will flow out through the lock hole 32 of the storage box 3.

[0025] Specifically, the sealing element 4 and the cover 1 and the water-retaining element 5 and the decorative cover 2 form an interference seal to ensure good sealing between the storage box 3 and the cover 1.

[0026] In some embodiments, the sealing element 4 includes an elastic element and a snap-fit ​​element. The snap-fit ​​element is provided with an elastic element and snaps into the storage box 3. A water-blocking element 5 is provided at the part of the snap-fit ​​element located on the decorative cover 2. The elastic element is elastic and can fit better with the cover 1 to ensure sealing and achieve the purpose of blocking water. The snap-fit ​​element is used to snap the sealing element 4 onto the storage box 3, providing conditions for the elastic element to fit into the cover 1. The snap-fit ​​element is snapped onto the storage box 3, which ensures quick installation and prevents the snap-fit ​​element from easily falling off, thereby ensuring that the sealing element 4 is firmly snapped in place and thus ensuring the sealing performance.

[0027] In some embodiments, the snap-fit ​​component includes a snap-fit ​​body 42, which snaps into the stop 33 of the storage box 3. The snap-fit ​​body 42 snaps into the stop 33 of the storage box 3, which not only provides conditions for the elastic element to fit with the cover 1, but also ensures that the sealing element 4 is firmly snapped in place, thereby ensuring the sealing performance.

[0028] In some embodiments, the inner wall of the snap-fit ​​body 42 is provided with barbed inner teeth 421, which snaps into the stop 33 of the storage box 3. The snap-fit ​​of the barbed inner teeth 421 into the stop 33 of the storage box 3 not only facilitates installation, but also ensures that the snap-fit ​​body 42 will not easily fall off, thereby making the sealing element 4 snap-fit ​​firmly and ensuring the sealing performance.

[0029] In some embodiments, the snap-fit ​​body 42 is provided with a skeleton 422; the skeleton 422 can ensure the clamping force and support of the snap-fit ​​body 42, and ensure that it does not deform during use, thereby ensuring that the seal 4 is snapped firmly, and thus ensuring the sealing performance of the seal 4.

[0030] In some embodiments, the skeleton 422 is U-shaped; the U-shaped skeleton 422 can ensure the clamping force and support of the snap-fit ​​body 42, and ensure that it does not deform during use, thereby ensuring that the seal 4 is snapped firmly, and thus ensuring the sealing performance of the seal 4.

[0031] Specifically, the material of the frame 422 can be selected, but is not limited to, steel core. The use of steel core in the frame 422 can ensure the clamping force and support of the snap-fit ​​body 42, and ensure that it will not deform during use.

[0032] In some embodiments, the snap-fit ​​body 42 is U-shaped; the U-shaped snap-fit ​​body 42 can ensure its own clamping force and support function, and ensure that it does not deform during use.

[0033] Specifically, the material of the snap-fit ​​body 42 can be selected, but is not limited to, EPDM adhesive. EPDM adhesive is existing technology, so it will not be described in detail here.

[0034] In some embodiments, the elastic element includes a hollow bubble tube 41, one end of which is connected to a snap-fit ​​element, and the other end of which is in contact with the machine cover 1. The hollow bubble tube 41 is elastic and can fit better with the machine cover 1 to ensure sealing and achieve the purpose of blocking water. The snap-fit ​​element provides support for the hollow bubble tube 41.

[0035] In some embodiments, the hollow tube 41 includes a tube body 411 and an inclined block 412. One end of the tube body 411 is connected to a snap-fit ​​component, and the end of the tube body 411 away from the snap-fit ​​component is provided with an inclined block 412. Both the end of the tube body 411 away from the snap-fit ​​component and the inclined block 412 are in contact with the cover 1. The tube body 411 is elastic and can fit better with the cover 1 to ensure sealing and achieve the purpose of blocking water. The inclined block 412 can prevent the tube body 411 from being squeezed into the storage box 3 when the seal 4 is compressed by the cover 1, thereby ensuring sealing.

[0036] Specifically, the materials for the tube body 411 and the inclined block 412 can be selected, but are not limited to, EPDM foam adhesive; the use of EPDM foam adhesive for the tube body 411 and the inclined block 412 improves the elasticity of the hollow tube 41 and allows for a better fit with the cover 1. EPDM foam adhesive is existing technology, so it will not be described in detail here.

[0037] Specifically, one end of the tube body 411 is connected to the snap-fit ​​body 42, and the end of the tube body 411 away from the snap-fit ​​body 42 is provided with an inclined block 412.

[0038] In some embodiments, the cross-section of the tube 411 is circular; when the tube 411 is compressed by the cover 1, the circular cross-section of the tube 411 can prevent the seal 4 from being squeezed into the storage box 3, thereby ensuring the sealing performance.

[0039] In some embodiments, the portion of the tube 411 facing the decorative cover 2 is provided with an inclined block 412; when the tube 411 is compressed by the cover 1, the inclined block 412 is provided on the portion of the tube 411 facing the decorative cover 2, which can prevent the seal 4 from being squeezed into the storage box 3, thereby ensuring the sealing performance.

[0040] In some embodiments, the inclined block 412 forms a sharp angle with the surface of the tube 411; when the tube 411 is compressed by the cover 1, the inclined block 412 forms a sharp angle with the surface of the tube 411, which can prevent the seal 4 from being squeezed into the storage box 3, thereby ensuring the sealing performance.

[0041] In some embodiments, the water-blocking component 5 includes a first water-blocking edge 51 and a second water-blocking edge 52. The sealing component 4 is provided with a first water-blocking edge 51 near the decorative cover 2. The end of the first water-blocking edge 51 away from the sealing component 4 overlaps with the decorative cover 2. The end of the first water-blocking edge 51 near the sealing component 4 is provided with a second water-blocking edge 52. The end of the second water-blocking edge 52 away from the sealing component 4 overlaps with the decorative cover 2. After water enters the sides of the car, the second water-blocking edge 52 plays a first water-blocking role, and the first water-blocking edge 51 plays a second water-blocking role. The double water-blocking can prevent most of the water from entering the water channel 31 of the storage box 3.

[0042] Specifically, the snap-fit ​​body 42 is provided with a first water-blocking edge 51 near the decorative cover 2. The end of the first water-blocking edge 51 away from the snap-fit ​​body 42 overlaps with the decorative cover 2. The end of the first water-blocking edge 51 near the snap-fit ​​body 42 is provided with a second water-blocking edge 52, so as to ensure that the first water-blocking edge 51 can overlap with the decorative cover 2 better.

[0043] Specifically, the materials for the first water-retaining edge 51 and the second water-retaining edge 52 can be selected, but are not limited to, EPDM foam adhesive. Using EPDM foam adhesive improves the elasticity of the first water-retaining edge 51 and the second water-retaining edge 52, allowing for a better fit with the decorative cover 2. EPDM foam adhesive is existing technology, so it will not be described in detail here.

[0044] The working principle of the sealing structure of the front compartment of an electric vehicle is as follows: By fitting the sealing element 4 to the cover 1 and the water-blocking element 5 to the decorative cover 2, a complete sealing performance can be formed. This not only effectively solves the problem of water and dust entering the front storage box 3, but also performs excellently in functions such as water blocking, water guiding and drainage.

[0045] The internal barbs 421 of the snap-fit ​​body 42 are snapped onto the stop 33 of the storage box 3. Simultaneously, the first and second water-blocking edges 51 and 52 overlap with the decorative cover 2. When the hood 1 is closed, it compresses the hollow bubble tube 41. At this time, a large amount of water entering from the windshield side is blocked by the hollow bubble tube 41 and the snap-fit ​​body 42, draining through the drainage hole 22 of the decorative cover 2 to the lower part of the front compartment and dripping outside the vehicle. Water entering from both sides of the vehicle is blocked by the first and second water-blocking edges 51 and 52. If some water enters the water channel 31 of the storage box 3 through the gap between the first and second water-blocking edges 51 and the decorative cover 2, it flows out through the lock hole 32 connecting the storage box 3 and the buckle 21. Therefore, the seal 4 fits snugly against the hood 1, and the water-blocking component 5 overlaps with the decorative cover 2, forming a complete seal and preventing dust from entering the storage box 3.

[0046] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
