Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, and more specifically, it relates to a waterproof structure for an in-vehicle multimedia player and a vehicle. Background Technology

[0002] Currently, the multimedia player in most car models is usually installed on the dashboard assembly. As a central processing controller, the multimedia player integrates functions such as audio-visual entertainment, navigation processing, and monitoring control, which can meet consumers' pursuit of vehicle personalization and technological feel, and has become a basic point of differentiation for car manufacturers.

[0003] However, after experimental verification and long-term practical use, the following problem was found in the installation location of the multimedia player: when the windshield is tinted, water will flow through the gap between the windshield and the dashboard assembly, enter the car through the windshield, and flow into the heat dissipation holes of the multimedia player along the front sheet metal, which will cause the multimedia player's mainboard to be corroded and burned. Utility Model Content

[0004] The purpose of this utility model is to provide a waterproof structure and vehicle for an in-vehicle multimedia player, aiming to solve the risk that water entering the vehicle along the windshield will flow onto the multimedia player and enter its interior, corroding the motherboard and electrical components.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a waterproof structure for a vehicle multimedia player is provided, comprising: a water-blocking component that is attached to the front of the front bulkhead sheet metal and located above the multimedia player; the water-blocking component and the front bulkhead sheet metal form a flow channel, the flow channel being located below the gap between the windshield and the dashboard assembly, guiding water flowing into the gap to the left and / or right side of the multimedia player to avoid the multimedia player.

[0006] The beneficial effects of the waterproof structure of the in-vehicle multimedia player provided by this utility model are as follows: Compared with the prior art, the waterproof structure of the in-vehicle multimedia player of this utility model, by setting a guide channel below the gap between the windshield and the dashboard assembly and above the multimedia player, allows water flowing down through the gap to fall into the guide channel and be guided to the left and / or right side of the multimedia player, preventing it from falling onto the multimedia player. This avoids the risk of water entering the interior of the multimedia player through its heat dissipation holes, thus preventing corrosion of the electrical components and motherboard inside the multimedia player, thereby increasing the service life of the multimedia player and reducing maintenance costs.

[0007] In conjunction with the first aspect, in one possible implementation, the water-blocking component is a foam component.

[0008] In the above technical solution, foam is used to make water-blocking parts. The foam has the characteristics of absorbing moisture and being flexible and easily deformable. It can be easily installed in the gap formed by the front sheet metal, the windshield and the instrument panel assembly, without damaging these parts.

[0009] In other cases, water-blocking components can also be made of flexible and elastic materials such as rubber and plastic, in order to fit into confined spaces without affecting the normal installation and configuration of surrounding main components.

[0010] In conjunction with the first aspect, in one possible implementation, the right and lower edges of the water-blocking component are attached to the front sheet metal, while the left side is open to form a guide port.

[0011] The above-mentioned technical solution uses a method of blocking one side and opening the other side to guide the water flow to discharge in one direction. This can reduce the uncertainty of diversion from both sides and avoid the risk of corrosion damage to relevant components inside the vehicle caused by diversion from multiple directions.

[0012] In conjunction with the first aspect, one possible implementation also includes a waterproof cover placed over the multimedia player, the waterproof cover being used to direct water flowing from the flow channel to the vicinity of the multimedia player, thereby avoiding the multimedia player.

[0013] To avoid the risk of water ingress and corrosion in the multimedia player, the above technical solution adopts a two-step approach. When the water flow is small, the water can be guided to the outside of the multimedia player using the flow channel on top of the multimedia player. When the water flow is large, a waterproof cover placed on the multimedia player prevents water from entering the multimedia player, thus fundamentally avoiding the problem of water entering the multimedia player.

[0014] In conjunction with the first aspect, in one possible implementation, the waterproof cover is provided with drainage curtains on its left and right sides to direct water flow away from the multimedia player, and the drainage curtains are bent downwards in an arc shape.

[0015] In the above technical solution, the curved drainage curtain reduces water flow resistance, allowing water to flow smoothly down the curved surface and reducing water stagnation and splashing on the curtain surface. At the same time, the curved structure can expand the drainage coverage area, keeping the water away from the waterproof cover and multimedia player during its descent, preventing water from dripping onto the side of the multimedia player.

[0016] In conjunction with the first aspect, in one possible implementation, the waterproof cover curves upward in an arc shape away from the rear end of the front sheet metal to form a rear water deflector.

[0017] In this application, the rear end of the waterproof cover is bent upwards, preventing water from flowing downwards from the rear end of the waterproof cover. This design is also determined by the structure of the rear side of the multimedia player and the surrounding environment. For example, if there are many heat dissipation holes on the rear surface of the multimedia player from top to bottom, even if a baffle is set to cover the rear surface, water droplets will still fall into the heat dissipation holes at the bottom and enter the interior of the multimedia player, corroding the motherboard and electrical components.

[0018] Because the waterproof cover designed in this application cannot completely enclose the multimedia player, heat dissipation is an essential aspect of ensuring the multimedia player's performance.

[0019] In conjunction with the first aspect, in one possible implementation, the waterproof cover curves downward in an arc shape near the front end of the front sheet metal, wrapping around the front side of the multimedia player to form a front protective curtain.

[0020] The above technical solution addresses the structure of the multimedia player by providing a protective curtain that wraps around its front side. The protective curtain is slightly tilted forward to guide the water flow along the curtain away from the multimedia player. In conjunction with the first aspect, in one possible implementation, the waterproof cover is provided with upwardly protruding reinforcing ribs that extend in the front-back direction, dividing the water-receiving surface of the waterproof cover into two water-guiding zones, left and right, to guide water flow from the left and right sides.

[0021] When the water flow is large, the water overflowing from the diversion channel will splash onto the waterproof cover, and its irregular flow on the cover will also cause some problems for drainage. This application solves this problem by setting reinforcing ribs on the waterproof cover to achieve zoned diversion of the water flow.

[0022] In conjunction with the first aspect, in one possible implementation, the reinforcing rib is L-shaped, with its longitudinal ribs extending in the front-back direction and its transverse ribs extending in the left-right direction, and is located at the front end of the waterproof cover, forming a semi-enclosed right water guiding area and an L-shaped left water guiding area.

[0023] In the above technical solution, the reinforcing ribs adopt an L-shaped structure, with longitudinal ribs extending in the front-to-back direction and transverse ribs extending in the left-to-right direction and concentrated at the front end of the waterproof cover, dividing the area into a semi-enclosed right water guiding zone and an L-shaped left water guiding zone. The semi-enclosed right water guiding zone guides the water flow to the right; the L-shaped left water guiding zone guides the water flow to the left, thus diverting the water to flow smoothly to both sides for drainage.

[0024] Secondly, this utility model embodiment also provides a vehicle, including the waterproof structure of the aforementioned in-vehicle multimedia player.

[0025] It is understandable that the beneficial effects of the second aspect mentioned above can be found in the relevant descriptions in the first aspect mentioned above, and will not be repeated here.

[0026] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this specification. Attached Figure Description

[0035] Multimedia players have become an indispensable part of vehicles. Because the multimedia player is installed in the gap between the windshield and the dashboard assembly, external water can easily enter the vehicle through the gap, run along the windshield, and flow down the front sheet metal to the multimedia player. It can then enter the interior through the heat dissipation holes of the multimedia player, causing corrosion and short circuits to the internal mainboard and other electrical components, affecting the user experience and thus having an adverse effect on the vehicle model.

[0036] To address the issue of water entering the multimedia player, this application proposes a method to divert the water flow to an area away from the multimedia player. The specific design scheme will be described later.

[0037] Figures 1 to 11 The installation location of the water-blocking component is shown from different angles and from all angles.

[0038] Please refer to the following: Figures 1 to 11 The waterproof structure of the in-vehicle multimedia player provided by this utility model will now be described. The waterproof structure of the in-vehicle multimedia player 7 includes a water-blocking component 3 that is attached to the front of the front bulkhead sheet metal 4 and located above the multimedia player 7; the water-blocking component 3 and the front bulkhead sheet metal 4 form a flow channel 8, which is located below the gap between the windshield glass 2 and the instrument panel assembly 1, and guides the water flowing into the gap to the left and / or right side of the multimedia player 7 to avoid the multimedia player 7.

[0039] The waterproof structure of the in-vehicle multimedia player 7 provided by this utility model, compared with the prior art, provides a guide channel 8 below the gap between the windshield 2 and the dashboard assembly 1 and above the multimedia player 7. Water flowing down through the gap falls into the guide channel 8 and is guided to the left and / or right side of the multimedia player 7, preventing it from falling onto the multimedia player 7. This avoids the risk of water entering the interior of the multimedia player 7 through its heat dissipation holes, which could lead to corrosion of the electrical components and motherboard inside the multimedia player 7. As a result, the service life of the multimedia player 7 is improved and maintenance costs are reduced.

[0040] In this application, a water-blocking component 3 is attached to the front of the front bulkhead sheet metal 4 to form a flow channel 8 that extends beyond the left and right edges of the multimedia player 7 in both directions. The water-blocking component 3 is fixed to the front bulkhead sheet metal 4 by attaching it to the surface, thus avoiding the risk of water dripping from the opening onto the multimedia player 7 due to poor sealing.

[0041] The water-blocking component 3 is fixed to the front bulkhead sheet metal 4 by adhesive. The lower edge of the water-blocking component 3 is tightly and firmly glued to prevent water leakage.

[0042] In some embodiments, see Figures 6 to 11 As shown, the water-blocking component 3 is made of foam. This application utilizes foam to make the water-blocking component 3, taking advantage of the moisture-absorbing properties of foam, as well as its flexible and easily deformable characteristics. It can be easily installed in the gap formed by the front bulkhead sheet metal 4, the windshield 2, and the instrument panel assembly 1, without causing damage to these components.

[0043] In other cases, the water-blocking component 3 can also be made of flexible and elastic materials such as rubber or plastic, so that it can be adapted to a small space without affecting the normal installation and configuration of the surrounding main components.

[0044] Using this water-blocking component 3 to construct the flow channel 8 on the multimedia player 7 can be quickly achieved without changing the structure and layout of the surrounding components, and has strong operability.

[0045] In some embodiments, see Figures 6 to 11 As shown, the right and lower edges of the water-blocking component 3 are attached to the front sheet metal 4, while the left side is open to form a guide port 10.

[0046] The above-mentioned technical solution sets up a flow channel 8 with one side blocked and the other side open, which guides the water flow to discharge in one direction. This can reduce the uncertainty of flow from both sides and avoid the risk of corrosion damage to related components inside the vehicle caused by multi-directional flow.

[0047] The above technical solution guides the water flow to the outside of the multimedia player 7 by setting up a flow channel 8. This method is suitable for small water flows. When the water flow is large, the water will overflow from the flow channel 8 and drip onto the multimedia player 7 below. In this case, a second step is needed to guide the water flow to the outside of the multimedia player 7. See [link to relevant documentation]. Figure 11 As shown by the arrows, arrow a indicates the direction of the water flow when the water flow is small, showing that the water flow is guided to the left side of the multimedia player 7, avoiding the multimedia player 7; arrow b indicates the direction of the water flow when the water flow is large, where the water overflowing from the guide channel 8 falls onto the waterproof cover 5 and is guided from the left and right sides to the outside of the multimedia player 7, avoiding the multimedia player 7.

[0048] See Figures 6 to 12 As shown, the waterproof structure of the vehicle multimedia player 7 provided by this utility model also includes a waterproof cover 5 covering the multimedia player 7. The waterproof cover 5 is used to guide the water that overflows from the guide channel 8 to the waterproof cover 5 to the surrounding area of ​​the multimedia player 7 so as to avoid the multimedia player 7.

[0049] The waterproof cover 5 completely covers the multimedia player 7, and extends beyond the four sides of the multimedia player 7 to prevent water from dripping onto the sides of the multimedia player 7.

[0050] As can be seen from the above technical solution, in order to avoid the risk of water ingress and corrosion of the multimedia player 7, this application adopts a two-step technical approach. When the water flow is small, the water flow can be guided to the outside of the multimedia player 7 by using the guide channel 8 on the top of the multimedia player 7; while when the water flow is large, the waterproof cover 5 covering the multimedia player 7 prevents the water flow from entering the interior of the multimedia player 7, thereby fundamentally avoiding the problem of water ingress into the multimedia player 7.

[0051] From an implementation perspective, since the multimedia player 7 is fixed to the dashboard reinforcement beam and also requires a bracket, this application only needs to widen and lengthen the bracket to cover the entire multimedia player 7 from above. No additional new structure is required, which saves costs and greatly shortens the implementation cycle.

[0052] In some embodiments, see Figures 10 to 12 As shown, the waterproof cover 5 has drainage curtains 52 on its left and right sides to direct water flow away from the multimedia player 7. The drainage curtains 52 are curved downwards.

[0053] The curved drainage curtain 52 reduces water flow resistance, allowing water to flow smoothly down the curved surface and reducing water stagnation and splashing on the curtain surface. At the same time, the curved structure expands the drainage coverage area, keeping the water away from the waterproof cover 5 and multimedia player 7 during its descent, preventing water from dripping onto the side of the multimedia player 7.

[0054] In practice, the structure or shape of the drainage curtains 52 on the left and right sides of the waterproof cover 5 can be the same or different, depending on the space on the left and right sides of the multimedia player 7, the structure on the left and right sides of the multimedia player 7 and other factors.

[0055] For example, in this application, the drainage curtain 52 on the left side of the multimedia player 7 extends beyond the left edge of the multimedia player 7 by a wider width, forming a water-blocking canopy structure (see...). Figure 11 The water flow is directed away from the multimedia player 7; while the right-side drainage curtain 52 wraps around the right side of the multimedia player 7, with only the lower edge having an outwardly bent flange 53 (see...). Figure 11 and Figure 12 ), guide the water flow away from the right side of the multimedia player 7.

[0056] In some embodiments, see Figures 10 to 12The rear end of the waterproof cover 5, away from the front sheet metal 4, curves upward in an arc shape to form a rear water baffle 54. In this application, the rear end of the waterproof cover 5 curves upward, preventing water from flowing downward from the rear end of the waterproof cover 5. This design is also determined by the structure of the rear side of the multimedia player 7 and the surrounding environment. For example, if there are many heat dissipation holes on the rear surface of the multimedia player 7 from top to bottom, even if a baffle is provided to cover its rear surface, water droplets will still fall into the heat dissipation holes below and enter the interior of the multimedia player 7, corroding the motherboard and electrical components.

[0057] Because the waterproof cover 5 provided in this application cannot completely cover the outside of the multimedia player 7, heat dissipation of the multimedia player 7 is an essential part of its protection.

[0058] Therefore, this application, through differentiated structural design of the sides around the multimedia player 7, specifically designs differentiated drainage and waterproofing structures around the waterproof cover 5, to ensure that the multimedia player 7 dissipates heat while achieving waterproofing, material saving, and without affecting surrounding interference components.

[0059] In some embodiments, see Figure 9 and Figure 12 As shown, the waterproof cover 5 curves downward in an arc shape near the front end of the front sheet metal 4, wrapping around the front side of the multimedia player 7 to form a front protective curtain 55.

[0060] This application addresses the structure of the multimedia player 7 by providing a front protective curtain 55 on its front side. The front protective curtain 55 is slightly tilted forward to guide the water flow along the front protective curtain 55 away from the multimedia player 7. When the water flow is large, the water overflowing from the guide channel 8 will splash onto the waterproof cover 5, and its irregular flow on the waterproof cover 5 will also cause some trouble for drainage. This application achieves zoned diversion of water flow by setting reinforcing ribs 51 on the waterproof cover 5.

[0061] In some embodiments, see Figure 10 and Figure 12 As shown, the waterproof cover 5 is provided with an upwardly protruding reinforcing rib 51. The reinforcing rib 51 extends in the front-back direction and divides the water-receiving surface of the waterproof cover 5 into two water-guiding areas, so as to guide the water flow to drip from the left and right sides.

[0062] The above-mentioned technical solution primarily directs water flow to the left and right sides of the multimedia player 7, which is a reasonable design consistent with the structure of the multimedia player 7. Generally speaking, similar to the host of a computer, the multimedia player 7 has many electrical or communication ports on its front and rear sides. Water cannot drip onto these ports, as this could easily cause poor contact, short circuits, and prevent normal signal transmission.

[0063] The reinforcing ribs also help to improve the waterproof cover's resistance to deformation.

[0064] In some embodiments, the reinforcing rib 51 is L-shaped, with its longitudinal ribs extending in the front-back direction and its transverse ribs extending in the left-right direction, and is located at the front end of the waterproof cover 5, forming a semi-enclosed right water guiding area 57 and an L-shaped left water guiding area 56.

[0065] The reinforcing rib 51 adopts an L-shaped structure, with longitudinal ribs extending in the front-to-back direction and transverse ribs extending in the left-to-right direction and concentrating at the front end of the waterproof cover 5, dividing it into a semi-enclosed right water guiding zone 57 and an L-shaped left water guiding zone 56. The semi-enclosed right water guiding zone 57 guides the water flow to the right; the L-shaped left water guiding zone 56 guides the water flow to the left, thus diverting the water to flow smoothly to both sides for drainage.

[0066] It should also be noted that when using the waterproof cover 5 to fix other components, such as fixing the wire harness 6 on the waterproof cover 5, after making a hole in the waterproof cover 5, the waterproof buckle 9 and the cable tie are used to restrain the wire harness 6.

[0067] Based on the same inventive concept, this application also provides a vehicle including the waterproof structure of the in-vehicle multimedia player 7.

[0068] The vehicle provided in this application utilizes this waterproof structure to quickly address the problem of water ingress into the multimedia player 7, reduce the frequency of malfunctions caused by corrosion due to water ingress, lower maintenance costs, and extend the service life of the multimedia player 7.

[0069] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
