Description

Technical Field

[0001] This utility model relates to the field of automotive black box technology, specifically to an automotive black box with a concealed waterproof data interface. Background Technology

[0002] A vehicle black box, also known as an onboard event data recording system, is an electronic device installed inside a car. It is mainly used to collect and store key data information such as speed, acceleration, braking status, steering angle, engine operating parameters, and collision information during the vehicle's operation in real time. After a traffic accident, the data recorded can serve as an important basis for accident cause analysis, liability determination, and vehicle performance evaluation, which is of great significance for improving the level of road traffic safety management.

[0003] Existing automotive black boxes typically connect to components such as the vehicle's CAN bus and sensors to continuously receive and process various dynamic data during vehicle operation. After being processed and encoded by an internal processor, the data is stored in the built-in storage unit. When data needs to be read, operators need to use data interfaces such as USB and Ethernet on the black box to connect to external devices via data cables to export and analyze the data.

[0004] Existing automotive black boxes generally lack effective waterproof sealing structures for their data interfaces. The interfaces are mostly open designs or only covered by simple dust covers, resulting in weak waterproof performance. When vehicles are in severe weather conditions that cause excessive water accumulation on the road or when driving through water, moisture can easily seep into the black box through the data interface, causing short circuits in the internal circuits and damage to electronic components. This can not only lead to the loss of recorded data but also prevent the black box from functioning properly, affecting its data retention and functionality in critical scenarios. Utility Model Content

[0005] The purpose of this invention is to provide a car black box with a hidden waterproof data interface, in order to solve the technical problem that the data interface of the existing car black box is generally not equipped with an effective waterproof sealing structure. When the vehicle is in a bad weather situation with excessive water on the road or driving through water, water can easily seep into the black box through the data interface, causing short circuits in the internal circuits and damage to electronic components.

[0006] The technical problem to be solved by this utility model can be achieved through the following technical solution:

[0007] A car black box with a concealed waterproof data interface includes a black box body; an upper shell is fixedly connected to the top of the black box body; a connection socket is fixedly connected to the side of the black box body; a connection plug shell is inserted into the connection socket, and both the connection socket and the connection plug shell are made of rubber; a first water-stop strip is fixedly connected inside the connection socket, and the first water-stop strip is located on one side of the connection plug shell; a positioning bolt is fixedly connected to the bottom of the black box body; and a sealing unit is provided inside the black box body.

[0008] As a further embodiment of this utility model: the sealing unit includes a second sealing strip; the second sealing strip is fixedly connected to the top of the black box body; a first sealing strip is fixedly connected inside the upper shell, and the interior of the first sealing strip is connected to the second sealing strip; a second water-stop strip is fixedly connected inside the second sealing strip, and the second water-stop strip is located below the first sealing strip.

[0009] As a further embodiment of this utility model: a first heat sink plate is fixedly connected to the bottom of the interior of the black box body; a second heat sink plate is connected to the bottom of the first heat sink plate; a heat sink fin is fixedly connected to the bottom of the second heat sink plate, and the heat sink fin has an air groove inside.

[0010] The beneficial effects of this utility model are as follows: By using rubber material for the connecting socket and the connecting plug shell, and by setting a No. 1 water-stop strip inside the connecting socket, a double waterproof structure can be formed. The connecting socket and the connecting plug shell tightly fit the outer wall of the interface due to their own elasticity, achieving an initial seal to block most of the water intrusion. When a small amount of water seeps in, the No. 1 water-stop strip expands upon contact with water, which can automatically fill the tiny gap between the rubber sleeve and the interface, further enhancing the sealing effect. This effectively prevents water from entering the black box through the connecting socket, thereby avoiding problems such as internal circuit short circuits, component damage, and data loss. It significantly improves the reliability and service life of the black box in harsh environments such as wading and heavy rain, ensuring its stable performance of data recording and storage functions in critical scenarios.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figures 1-5 As shown, a car black box with a concealed waterproof data interface includes a black box body 1; an upper shell 2 is fixedly connected to the top of the black box body 1; a connecting socket 3 is fixedly connected to the side of the black box body 1; a connecting plug shell 4 is inserted into the inside of the connecting socket 3, and the connecting socket 3 and the connecting plug shell 4 are made of rubber; a first water-stop strip 6 is fixedly connected inside the connecting socket 3, and the first water-stop strip 6 is located on one side of the connecting plug shell 4; a positioning bolt 5 is fixedly connected to the bottom of the black box body 1; and a sealing unit is provided inside the black box body 1.

[0020] During operation, it is connected and fixed to the vehicle body via positioning bolts 5. The connecting socket 3 and connecting plug shell 4 are made of rubber, providing excellent waterproofing. After the connecting plug shell 4 is inserted into the connecting socket 3, the bottom end of the first water-stop strip 6 will adhere to the surface of the connecting plug shell 4. The first water-stop strip 6 expands upon contact with water, further enhancing the waterproofing effect of the connecting socket 3 and connecting plug shell 4. Through the rubber material of the connecting socket 3 and connecting plug shell 4, and the placement of the first water-stop strip 6 inside the connecting socket 3, a double waterproof structure is formed. With its own elasticity, it fits tightly against the outer wall of the interface to achieve an initial seal and prevent most water from entering. When a small amount of water seeps in, the No. 1 water-stop strip 6 expands after encountering water, which can automatically fill the tiny gap between the rubber sleeve and the interface, further enhancing the sealing effect. This effectively prevents water from entering the black box 1 through the connection socket 3, thereby avoiding problems such as internal circuit short circuits, component damage, and data loss. It significantly improves the reliability and service life of the black box 1 in harsh environments such as wading and heavy rain, and ensures that its data recording and storage functions can be stably performed in critical scenarios.

[0021] The sealing unit includes a second sealing strip 8; the second sealing strip 8 is fixed to the top of the black box body 1; the inside of the upper shell 2 is fixed to a first sealing strip 7, and the inside of the first sealing strip 7 is connected to the second sealing strip 8; the inside of the second sealing strip 8 is fixed to a second water-stop strip 9, and the second water-stop strip 9 is located below the first sealing strip 7.

[0022] The black box body 1 and the upper shell 2 are fixed together by screws. When the black box body 1 and the upper shell 2 are fixed together, the second sealing strip 8 at the top of the black box body 1 will enter the first sealing strip 7 inside the upper shell 2. The first sealing strip 7 and the second sealing strip 8 are made of rubber, which can improve the sealing performance of the black box body 1 and the upper shell 2 and reduce the amount of water entering the interior of the black box body 1. The second water-stop strip 9 is located between the first sealing strip 7 and the second sealing strip 8. When water enters the gap between the first sealing strip 7 and the second sealing strip 8, the second water-stop strip 9 will expand to improve the sealing performance between the black box body 1 and the upper shell 2.

[0023] A first heat sink 10 is fixedly connected to the bottom of the interior of the black box 1; a second heat sink 11 is connected to the bottom of the first heat sink 10; a heat sink 12 is fixedly connected to the bottom of the second heat sink 11, and the heat sink 12 has an air duct inside.

[0024] The black box 1 generates heat during operation. Before operation, the second heat sink 11 is installed at the bottom of the first heat sink 10. It can be installed with screws. The first heat sink 10 and the second heat sink 11 have good heat absorption effect. The heat of the black box 1 is transferred to the first heat sink 10 and the second heat sink 11. The heat is diffused and discharged through the bottom of the second heat sink 11. The heat sink 12 can absorb the heat of the second heat sink 11. The external airflow can come into contact with the heat sink 12 and carry away the heat on the heat sink 12, thereby improving the heat dissipation effect of the black box 1.

[0025] The working principle of this utility model is as follows: During operation, it is connected and fixed to the vehicle body via positioning bolts 5. The connecting socket 3 and the connecting plug shell 4 are made of rubber, which has a good waterproof effect. After the connecting plug shell 4 is inserted into the connecting socket 3, the bottom end of the first water-stop strip 6 will adhere to the surface of the connecting plug shell 4. The first water-stop strip 6 will expand when it comes into contact with water, which can improve the waterproof effect of the connecting socket 3 and the connecting plug shell 4. Through the rubber material of the connecting socket 3 and the connecting plug shell 4, and the first water-stop strip 6 set inside the connecting socket 3, a double waterproof structure can be formed. The connector housing 4, with its own elasticity, tightly fits the outer wall of the interface, achieving an initial seal to prevent most moisture from entering. When a small amount of moisture seeps in, the first water-stop strip 6 expands upon contact with water, automatically filling the tiny gaps between the rubber sleeve and the interface, further enhancing the sealing effect. This effectively prevents moisture from entering the black box 1 through the connector socket 3, thus avoiding problems such as internal circuit short circuits, component damage, and data loss. This significantly improves the reliability and service life of the black box 1 in harsh environments such as wading and heavy rain, ensuring its stable data recording and storage functions in critical scenarios. The black box body 1 and the upper shell 2 are fixed together with screws. When the black box body 1 and the upper shell 2 are fixed together, the second sealing strip 8 at the top of the black box body 1 will enter the first sealing strip 7 inside the upper shell 2. The first sealing strip 7 and the second sealing strip 8 are made of rubber, which can improve the sealing performance of the black box body 1 and the upper shell 2 and reduce the ingress of water into the interior of the black box body 1. The second water-stop strip 9 is located between the first sealing strip 7 and the second sealing strip 8. When water enters the gap between the first sealing strip 7 and the second sealing strip 8, the second water-stop strip 9 will expand to improve the sealing performance of the black box body 1 and the upper shell 2. The black box 1 generates heat during operation. Before operation, the second heat sink 11 is installed at the bottom of the first heat sink 10. It can be installed with screws. The first heat sink 10 and the second heat sink 11 have good heat absorption effect. The heat of the black box 1 is transferred to the first heat sink 10 and the second heat sink 11. The heat is diffused and discharged through the bottom of the second heat sink 11. The heat sink 12 can absorb the heat of the second heat sink 11. The external airflow can contact the heat sink 12 and carry away the heat on the heat sink 12, thereby improving the heat dissipation effect of the black box 1.

However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
