Detailed Description

The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

In order to better understand the aspects of the present application, a further detailed description of the present application will be provided below with reference to the accompanying drawings and detailed description.

The terms "upper end, lower end, left side, right side" and the like are defined based on the drawings of the specification.

Referring to fig. 1 to 3, a waterproof case 110 provided in an embodiment of the present application is used for a front view controller 100 of a vehicle, the waterproof case 110 includes a first case 111 and a second case 112 connected to each other, one of the first case 111 and the second case 112 is provided with a groove 1111, and the other is provided with a waterproof seal groove 1121; in addition, the waterproof housing 110 further includes a waterproof sealing member 113, and the waterproof sealing member 113 is fixedly connected to the groove 1111 and extends out of the groove 1111, and when the first housing 111 and the second housing 112 are connected, at least a portion of the waterproof sealing member 113 is embedded in the waterproof sealing groove 1121, so that the waterproof sealing groove 1121 is fully covered with the waterproof sealing member 113.

Preferably, the first case 111 and the second case 112 serve as an upper case and a lower case of the waterproof case 110, respectively, and the upper case and the lower case are assembled to form an integral structure of the waterproof case 110. Generally, as the waterproof case 110 of the vehicle front view controller 100, a reliable waterproof sealing property should be ensured for protecting the control circuit board 120 inside thereof.

In order to ensure the connection reliability and waterproof tightness, the upper and lower housings may be fastened/adhered and then fastened by the screws 150, thereby solving the problem of unreliable connection tightness.

It can be seen that when the first housing 111 is provided with the groove 1111 and the second housing 112 is provided with the waterproof sealing groove 1121, the waterproof sealing member 113 is fixedly connected to the groove 1111 and extends out of the groove 1111, meanwhile, the waterproof sealing member 113 can fill the waterproof sealing groove 1121 when the first housing 111 and the second housing 112 are connected, so that the waterproof sealing groove 1121 is fully covered with the waterproof sealing member 113, and after the first housing 111 and the second housing 112 are connected, the waterproof sealing member 113 can fill or seal the gap existing in the groove 1111 and the waterproof sealing groove 1121, so that the inner cavity formed by the first housing 111 and the second housing 112 is in a closed state, and the problem of unreliable connection tightness is solved.

By adopting the arrangement mode, the sealing reliability is good, and the waterproof effect is good, so that the use requirement of the vehicle front view controller 100 can be met.

Of course, the groove 1111 may be filled with the waterproof seal 113, or it may be ensured that there is no gap between the waterproof seal 113 and the groove 1111 in the assembly direction of the first housing 111 and the second housing 112.

In some embodiments, the waterproof sealing member 113 is an elastic substrate integrally formed in the groove 1111 by dispensing.

Specifically, referring to fig. 4 to 6, the groove 1111 of the first housing 111 is designed as a concave dispensing groove, and the dispensing groove can be directly formed in a mold, and it should be noted that the dispensing groove needs to be smooth and free of oil stains and has a relatively strong surface energy.

In some embodiments, the waterproof seal 113 is one or more of a foamed rubber seal, an epoxy seal, an acrylate seal, and a polychlorinated ester seal.

That is, the waterproof sealing material 113 may be made of a material such as foamed rubber, epoxy resin, acrylate resin, and polychlorinated ester. In this way, the elastic base material is regularly dispensed according to the shape of the dispensing slot by the dispenser, so that the elastic base material fills the whole groove 1111 and gaps are prevented from being formed in the groove 1111.

When assembling, firstly, the elastic base material is regularly dispensed in the first shell 111 according to the shape of the dispensing groove through the dispensing needle 200 of the dispensing machine, then, the waterproof sealing piece 113 formed after dispensing is aligned with the waterproof sealing groove 1121 on the second shell 112 and clamped into the waterproof sealing groove 1121, and finally, the first shell 111 and the second shell 112 are locked and connected through the screw 150.

It can be appreciated that, since the waterproof sealing member 113 is made of an elastic material, the surface of the waterproof sealing member 113 is soft and has a certain elasticity, so that the waterproof sealing member 113 can be compressed under a certain pressure environment (the first shell 111 and the second shell 112 are connected by adopting a connection mode of locking the screw 150), at this time, at least part of the waterproof sealing member 113 can enter the waterproof sealing groove 1121 and can completely fill the whole waterproof sealing groove 1121 so as to fill or seal the gap existing in the waterproof sealing groove 1121, so that the inner cavity formed by combining the first shell 111 and the second shell 112 is completely sealed, and water cannot enter the waterproof shell 110, thereby solving the problem that the connection tightness of the waterproof shell 110 is unreliable.

It should be emphasized that the waterproof sealing member 113 is formed by dispensing, that is, the waterproof sealing member 113 adopts a dispensing integrated forming structure, on one hand, the waterproof sealing member 113 can be directly connected to the groove 1111 of the first housing 111, on the other hand, the groove 1111 can be fully covered with the waterproof sealing member 113, and the sealing reliability of the connection between the waterproof sealing member 113 and the first housing 111 is ensured.

Of course, a certain gap may be reserved between the waterproof sealing member 113 and the inner walls of the left and right sides of the groove 1111.

Of course, according to actual needs, the waterproof sealing member 113 may be formed and then connected to the groove 1111 of the first housing 111, provided that the waterproof sealing member 113 is fully distributed in the groove 1111, and the sealing reliability of the connection between the waterproof sealing member 113 and the first housing 111 is ensured.

In this embodiment, the waterproof sealing member 113 is preferably formed integrally with the groove 1111 by dispensing an elastic substrate.

In some embodiments, the end of the waterproof seal 113 remote from the groove 1111 is provided with an elastic protrusion that fits into the waterproof seal groove 1121 such that the elastic protrusion fills the waterproof seal groove 1121 when the first and second housings 111 and 112 are connected.

The elastic bulge is formed during the final step of the dispenser, and protrudes in a direction away from the groove 1111, so that the waterproof sealing member 113 is conveniently filled with the waterproof sealing groove 1121 under the pressure. Because the waterproof sealing member 113 has a softer surface and a certain elasticity, the waterproof sealing member 113 can be compressed downwards under a certain pressure environment (namely, when the screw 150 locks the first shell 111, the second shell 112 and the circuit board), wherein a part of the waterproof sealing member 113 (elastic protruding part) can enter the waterproof sealing groove 1121 and can completely fill the waterproof sealing groove 1121, so that the inner cavity formed by the first shell 111 and the second shell 112 is completely sealed, and water cannot enter the waterproof shell 110.

In some embodiments, referring to fig. 7 and 8 together, the end of the waterproof sealing member 113 away from the groove 1111 is a spherical end 1131, the spherical end 1131 has a guiding spherical surface 11311, and the guiding spherical surface 11311 is used to clamp the spherical end 1131 into the area where the waterproof sealing grooves 1121 are located and fill at least two waterproof sealing grooves 1121 when the first housing 111 and the second housing 112 are connected.

Referring to fig. 9 and 10 together, in the present embodiment, at least two, preferably two, waterproof sealing grooves 1121 are provided, and two waterproof sealing grooves 1121 are disposed side by side on the outer surface of the second housing 112, and when the first housing 111 and the second housing 112 are connected, the guiding spherical surface 11311 can ensure that the spherical end 1131 of the waterproof sealing member 113 can be smoothly clamped into the area where the waterproof sealing groove 1121 is located and fill the two waterproof sealing grooves 1121. The cooperation of the two waterproof sealing grooves 1121 and the waterproof sealing member 113 can further enhance the waterproof sealing property.

In some embodiments, the waterproof sealing groove 1121 is disposed on the surface of the second housing 112, the surface of the second housing 112 is provided with a flange 1122, and the flange 1122 is located outside the waterproof sealing groove 1121 and protrudes from the surface of the second housing 112.

It can be seen that when water in the external environment flows down through the first housing 111, some water may enter the product along the sidewall of the first housing 111, so that the product may fail, the waterproof flange 1122 may serve as a first waterproof structure, and the height of the waterproof flange 1122 may be higher than the surface of the second housing 112, so that the difficulty of entering the interior of the housing is increased.

Further, in consideration of the flow path of the external rainwater, a water blocking groove 1112 may be provided on the inner side wall of the first housing 111 opposite to the flange 1122, and the structure and the number of the water blocking grooves 1112 may be set as required, provided that the external rainwater can be prevented from entering the interior of the housing as much as possible, as shown in fig. 3.

In this way, the water blocking groove 1112 and the waterproof flange 1122 can be used as a first waterproof structure, so that the difficulty of water entering the housing is increased, the waterproof sealing member 113, the groove 1111 and the waterproof sealing groove 1121 form a second waterproof structure together, so that the inner cavity formed by the combination of the first housing 111 and the second housing 112 is completely sealed, and water cannot enter the waterproof housing 110.

In some embodiments, referring to fig. 11 and 12, the first housing 111 is provided with a hole 1113 and a waterproof cover 1115 covering the periphery of the hole 1113.

Generally, as the waterproof housing 110 of the vehicle front view controller 100, a hole 1113 for attaching the connection base 1114 is provided in the waterproof housing 110, and a waterproof cover 1115 may be provided around the connection base 1114 and the hole 1113 where the connection base 1114 is located in order to facilitate waterproofing of the connection base 1114.

In some embodiments, the top of the waterproof cover 1115 is provided with a first waterproof surface 11151 and a second waterproof surface 11152, and the first waterproof surface 11151 and the second waterproof surface 11152 are disposed above the hole site 1113 with a preset included angle.

For example, a roof-type (Y-type) waterproof structure is adopted, the whole structure is similar to a roof, when water flows from the upper part, the water flows outwards along an oblique angle formed by the first waterproof surface 11151 and the second waterproof surface 11152, and finally the water flows out of the product along the outer side wall directions of the first waterproof surface 11151 and the second waterproof surface 11152, so that a good waterproof effect is achieved.

Referring to fig. 13, a vehicle front view controller 100 provided in the present application includes a control circuit board 120, and a waterproof housing 110 for accommodating the control circuit board 120 as described in the above embodiments.

Referring to fig. 14 and 15 together, the vehicle front view controller 100 further includes a camera 130, and in order to ensure the connection tightness between the camera 130 and the waterproof housing 110, similarly, a camera seal 140 may be disposed at a position where the camera 130 is mounted on the first housing 111, where the camera seal 140 may be disposed in a manner that refers to the manner in which the waterproof seal 113 is disposed when the first housing 111 and the second housing 112 are connected, and correspondingly, a camera seal groove 141 corresponding to the waterproof seal 113 is disposed on the camera 130.

It should be noted that in this specification relational terms such as first and second are used solely to distinguish one entity from another entity without necessarily requiring or implying any actual such relationship or order between such entities.

The vehicle front view controller and the waterproof housing thereof provided by the present application are described in detail above. Specific examples are employed herein to illustrate the principles and embodiments of the present application, and the above examples are provided only to assist in understanding the aspects of the present application and their core ideas. It should be noted that it would be obvious to those skilled in the art that various improvements and modifications can be made to the present application without departing from the principles of the present application, and such improvements and modifications fall within the scope of the claims of the present application.
