[0035] In order to more clearly understand the above-mentioned objects, features and advantages of the present application, the solutions of the present application will be further described below. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0036] Many specific details are set forth in the following description in order to fully understand the present application, but the present application can also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present application, rather than all of the embodiments.

[0037] Refer to Figures 1 to 10 As shown, this embodiment provides a protection structure for a ceiling-mounted screen main board 30, including a protective part 1 and an elastic seal 2.

[0038] Specifically, referring to Figures 1 to 4 As shown, the protective member 1 has a receiving cavity 11 for receiving the ceiling screen main board 30 and is connected to the mounting bracket 9 of the ceiling screen main board 30. An installation hole 3 communicating with the receiving cavity 11 is formed in the protective member 1. The sealing member 2 is connected in the installation hole 3. The outer wall of the sealing member 2 abuts against the hole wall of the installation hole 3. An avoidance hole 21 for the wire harness 20 of the ceiling screen main board 30 to pass through is formed in the sealing member 2, and the avoidance hole 21 can be elastically opened and closed so that the hole wall of the avoidance hole 21 abuts against the wire harness 20.

[0039] The ceiling screen main board 30 is arranged in the receiving cavity 11 of the protective member 1, and the protective member 1 covers and shields the ceiling screen main board 30. On the one hand, the protective member 1 has a sealing and protective effect on the ceiling screen main board 30, avoiding the phenomenon that water vapor, dust, etc. enter the main board and cause the main board to short-circuit, which helps to extend the service life of the ceiling screen main board 30; on the other hand, the protective member 1 also has a protective effect on the ceiling screen main board 30, to a certain extent avoiding the phenomenon that the main board and its components are hit, further ensuring the service life of the ceiling screen main board 30.

[0040] In some implementation manners, the protective member 1 can be, for example, a protective cover, which has a simple structure, is easy to mold, and has good sealing and protection performance.

[0041] Among them, the protective cover can be made of plastic, for example. Exemplarily, the protective cover is made of a mixture of polycarbonate and ABS plastic (a terpolymer of three monomers: acrylonitrile (A), butadiene (B), and styrene (S)).

[0042] In some other implementation manners, the protective member can be, for example, a hollow protective shell.

[0043] During specific implementation, the joint between the protective member 1 and the mounting bracket 9 is sealed, so that the protective member 1 has higher protection performance for the ceiling screen main board 30.

[0044] By providing an installation hole 3 on the protective member 1 for the wire harness 20 to pass through, connecting a seal 2 in the installation hole 3, and making the outer wall of the seal 2 abut against the hole wall of the installation hole 3, that is, sealing is provided between the seal 2 and the installation hole 3. Moreover, an avoidance hole 21 for the wire harness 20 to pass through is provided on the seal 2, and the avoidance hole 21 can elastically open and close. That is, in the radial direction of the avoidance hole 21, the hole wall of the avoidance hole 21 can elastically expand and contract in a manner of approaching or moving away from the hole wall of the installation hole 3, so that the hole wall of the avoidance hole 21 always abuts against the outer wall of the wire harness 20. That is to say, sealing is provided between the wire harness 20 and the avoidance hole 21, so that a sealed connection is formed between the wire harness 20 and the seal 2. Since sealing is also provided between the seal 2 and the installation hole 3, sealing is provided between the wire harness 20 and the installation hole 3, and further sealing is provided between the wire harness 20 and the protective member 1, preventing moisture, dust, etc. from entering the protective member 1 from the wire harness 20, further avoiding the occurrence of a short circuit of the main board, and further extending the service life of the ceiling screen main board 30, making the service life of the in-vehicle ceiling screen with the ceiling screen main board 30 higher.

[0045] That is to say, by connecting an elastic seal 2 in the installation hole 3 of the protective member 1, making the seal 2 abut against the hole wall of the installation hole 3, and providing an avoidance hole 21 on the seal 2 that can elastically open and close, with the diameter of the avoidance hole 21 being smaller than the diameter of the wire harness 20, the wire harness 20 of the ceiling screen main board 30 is passed through the avoidance hole 21, so that sealing can be achieved at the position where the wire harness 20 passes through the protective member 1, and thus the protective member 1 has a better sealing and protecting effect on the main board.

[0046] In some implementation manners, the seal 2 can be made of silicone, for example, and its hardness can be about 65 - 75, with good elastic deformation performance.

[0047] Specifically, the seal 2 can be a sealing ring that matches the shape of the installation hole 3, for example. Among them, the outer diameter of the sealing ring is larger than the diameter of the installation hole 3. The inner ring space of the sealing ring forms an avoidance hole 21 for the wire harness 20 to pass through, and the outer ring wall of the sealing ring abuts against the hole wall of the installation hole 3.

[0048] The protective structure of the ceiling screen main board 30 provided by this application, by setting the protective member 1 and the elastic sealing member 2, the protective member 1 has a receiving cavity 11 for receiving the ceiling screen main board 30, and the protective member 1 is connected to the mounting bracket 9 of the ceiling screen main board 30. An installation hole 3 communicating with the receiving cavity 11 is opened on the protective member 1. The sealing member 2 is connected in the installation hole 3, the outer wall of the sealing member 2 abuts against the hole wall of the installation hole 3, and an avoidance hole 21 for the wire harness 20 of the ceiling screen main board 30 to pass through is opened on the sealing member 2, and the avoidance hole 21 can elastically open and close so that the hole wall of the avoidance hole 21 abuts against the wire harness 20. With such a setting, the ceiling screen main board 30 is arranged in the protective member 1, and the protective member 1 is connected to the mounting bracket 9 for mounting the ceiling screen main board 30, with a stable structure. The ceiling screen main board 30 is covered and shielded by the protective member 1, achieving a sealing and protective effect on the ceiling screen main board 30, to a certain extent avoiding the phenomenon that water vapor, dust, etc. enter the ceiling screen main board 30 and cause the main board to short-circuit, helping to extend the service life of the ceiling screen main board 30 and ensuring the service life of the vehicle-mounted ceiling screen with this ceiling screen main board 30. At the same time, an installation hole 3 is opened on the protective member 1, and an elastic sealing member 2 is connected in the installation hole 3, and the outer wall of the sealing member 2 abuts against the hole wall of the installation hole 3, that is, a sealed setting is provided between the sealing member 2 and the installation hole 3, and the sealing performance between the two is relatively good. An avoidance hole 21 is also opened on the sealing member 2, and the wire harness 20 on the ceiling screen main board 30 passes through the avoidance hole 21 of the sealing member 2. Since the avoidance hole 21 can elastically open and close, the hole wall of the avoidance hole 21 always abuts against the outer wall of the wire harness 20, that is, a sealed setting is provided between the wire harness 20 and the avoidance hole 21, ensuring the sealing performance between the wire harness 20 and the avoidance hole 21, thereby avoiding water vapor, dust, etc. from entering the protective member 1 from the wire harness 20, further avoiding the phenomenon of the main board short-circuiting, and further extending the service life of the ceiling screen main board 30, making the service life of the vehicle-mounted ceiling screen with this ceiling screen main board 30 higher.

[0049] In some embodiments, referring to Figures 4 to 7 As shown, a first connecting portion 41 is provided on the hole wall of the installation hole 3, and a second connecting portion 42 is provided on the outer wall of the sealing member 2. The sealing member 2 is connected to the installation hole 3 through the first connecting portion 41 and the second connecting portion 42.

[0050] That is to say, the sealing member 2 is installed in the installation hole 3 through the cooperation of the first connecting portion 41 and the second connecting portion 42 and abuts against the hole wall of the installation hole 3, thereby realizing the sealed setting between the sealing member 2 and the installation hole 3, ensuring the sealing and protection of the ceiling screen main board 30, and further avoiding the phenomenon that water vapor, dust, etc. enter the ceiling screen main board 30 and cause it to short-circuit.

[0051] In some embodiments, referring to Figures 4 to 7As shown, the first connecting portion 41 is a clamping projection, and the second connecting portion 42 is a clamping groove into which the clamping projection can extend. The structure is simple, easy to manufacture, and the connection is convenient and stable.

[0052] At the same time, the sealing member 2 can be detachably connected to the mounting hole 3 through the cooperation of the clamping projection and the clamping groove. If one of the protective member 1 and the sealing member 2 is damaged, only the two need to be disassembled and separated, and the damaged one can be replaced. The installation and disassembly are convenient, which is conducive to replacement and helps to save maintenance costs.

[0053] Moreover, the cooperation of the clamping projection and the clamping groove has a certain axial limiting effect on the sealing member 2, making the structure of the sealing member 2 in the mounting hole 3 more stable.

[0054] In some other embodiments, the first connecting portion can be, for example, a clamping groove formed on the inner wall of the mounting hole, and the second connecting portion is a clamping projection provided on the outer wall of the sealing member.

[0055] In some embodiments, referring to Figure 4 and Figure 5 as shown, the clamping projection is an annular clamping projection arranged circumferentially along the mounting hole 3, and the clamping groove is an annular clamping groove formed on the outer wall of the sealing member 2. The shape of the annular clamping projection matches the shape of the annular clamping groove.

[0056] Through the cooperation of the annular clamping projection and the annular clamping groove, the contact area between the sealing member 2 and the mounting hole 3 is increased, so that the connection strength between the sealing member 2 and the mounting hole 3 is relatively high, and thus the connection of the sealing member 2 in the mounting hole 3 is more stable and firm, and the structural stability is better.

[0057] In some embodiments, referring to Figure 4 and Figure 5 as shown, along the axial direction of the mounting hole 3, the size of the clamping projection is smaller than the depth of the mounting hole 3, and the clamping projection is centered. That is to say, the thickness of the clamping projection is smaller than the depth of the mounting hole 3, and the clamping projection is centered in the axial direction of the mounting hole 3, so that the axial limiting effect of the cooperation between the clamping projection and the clamping groove on the sealing member 2 is better, further enhancing the connection strength between the sealing member 2 and the mounting hole 3.

[0058] In some embodiments, the sealing member 2 is detachably connected to the mounting hole 3. With this setting, if one of the protective member 1 and the sealing member 2 is damaged, only the two need to be disassembled and separated, and the damaged one can be replaced. The installation and disassembly are convenient, which is conducive to replacement and helps to save maintenance costs.

[0059] In some other embodiments, a plurality of clamping projections are provided on the inner wall of the mounting hole, and the plurality of clamping projections are arranged at intervals circumferentially along the mounting hole. Correspondingly, a plurality of clamping grooves are provided on the outer wall of the sealing member, and one clamping projection corresponds to one clamping groove.

[0060] In some embodiments, referring toFigures 1 to 3 As shown, there are at least two mounting holes 3 and at least two seals 2, and the mounting holes 3 and the seals 2 are arranged in one-to-one correspondence. The number of mounting holes 3 is the same as the number of wire harnesses 20 led out from the ceiling-mounted screen main board 30. In this way, each wire harness 20 can be hermetically arranged at the penetration position on the protective part 1, so that the protective part 1 has a better sealing and protective effect on the main board.

[0061] In some embodiments, referring to Figures 1 to 3 As shown, at least two connecting ears 5 are provided on the side wall of the protective part 1. At least one first connecting hole 61 is formed in each connecting ear 5. At least two second connecting holes 62 are formed in the mounting bracket 9. One first connecting hole 61 corresponds to one second connecting hole 62. The protective part 1 is connected to the mounting bracket 9 by fasteners such as screws passing through the first connecting hole 61 and the second connecting hole 62. The structure is simple, and the connection is convenient and stable.

[0062] Exemplarily, referring to Figures 1 to 3 , four connecting ears 5 are provided on the side wall of the protective part 1. The four connecting ears 5 are arranged at intervals along the circumferential direction of the protective part 1, and one first connecting hole 61 is formed in each connecting ear 5. Referring to Figure 9 and Figure 10 As shown, a second connecting hole 62 is formed in the mounting bracket 9 at the position corresponding to each first connecting hole 61. The first connecting hole 61 and the second connecting hole 62 are arranged in one-to-one correspondence. The protective part 1 is connected together by screws passing through each group of first connecting holes 61 and second connecting holes 62.

[0063] Among them, the connecting ear 5 can be integrally formed with the protective part 1, which has good integrity and high structural strength. Of course, the connecting ear 5 can also be fixed on the protective part 1 by connecting pieces such as bolts.

[0064] In some embodiments, referring to Figures 1 to 3 As shown, at least two first positioning parts 71 are provided on at least two connecting ears 5. At least two second positioning parts 72 are formed in the mounting bracket 9. When the first positioning part 71 and the second positioning part 72 cooperate, the corresponding first connecting hole 61 and the second connecting hole 62 are coaxially arranged. That is to say, when the first positioning part 71 on the protective part 1 and the second positioning part 72 on the mounting bracket 9 cooperate, the first connecting hole 61 on the protective part 1 and the corresponding second connecting hole 62 on the mounting bracket 9 can be aligned, which is convenient for the screws to pass through and connect.

[0065] In some other embodiments, the first positioning part can also be directly provided on the outer wall of the protective part.

[0066] In some implementation manners, the first positioning part 71 is a positioning hole, and the second positioning part 72 is a positioning convex that can be inserted into the positioning hole. The structure is simple, and the positioning is convenient and reliable.

[0067] Exemplarily, with reference to Figures 1 to 3 and Figure 9 and Figure 10 as shown, a positioning hole is respectively formed on each of the two connecting lugs 5, and two positioning protrusions are provided on the mounting bracket 9, and each positioning protrusion corresponds to a positioning hole respectively.

[0068] In some other implementation manners, the first positioning portion is a positioning protrusion provided on the connecting lug, and the second positioning portion is a positioning hole provided on the mounting bracket.

[0069] With reference to Figure 9 and Figure 10 as shown, the mounting bracket 9 may include, for example, a bracket body 91 and a lining plate 92, and the bracket body 91 is located between the lining plate 92 and the protective member 1.

[0070] Specifically, a first avoidance opening is provided at the position of the bracket body 91 corresponding to the second connection hole 62; a connection post is provided at the position of the lining plate 92 corresponding to the second connection hole 62, the connection post is inserted into the first avoidance opening, and the second connection hole 62 is an internal thread hole formed on the connection post.

[0071] A second avoidance opening is provided at the position of the bracket body 91 corresponding to the positioning hole; a positioning protrusion is provided at the position of the lining plate 92 corresponding to the positioning hole, and the positioning protrusion is inserted into the second avoidance opening.

[0073] In some implementation manners, the sealing ring 8 may be, for example, a sealing ring matching the outer contour of the open end. Among them, the ring width of the sealing ring is not less than the wall thickness of the protective member 1 at the open end.

[0074] Specifically, the sealing ring 8 may be, for example, a sealing foam.

[0075] At least one side of the sealing ring 8 is provided with an adhesive layer, such as double-sided tape, so that the sealing ring 8 is adhered to the protective member 1 and / or the mounting bracket 9, and the connection is convenient.
