Summary of the invention

[0010] Furthermore, the use of a snap-on structure simplifies the assembly and disassembly process between the cover and the shell, making the operation simple and quick, and reducing maintenance costs. In addition, the snap-on method has good reusability, and can still maintain the original sealing effect after multiple disassembly and assembly; at the same time, the snap-on design also has excellent impact and shock resistance, which can protect the storage components from damage during transportation and use.

[0011] In one example of the present application, the cover is provided with an elastic component.

[0019] Specifically, the present solution provides a first mounting bracket and a second mounting bracket on a side of the housing away from the storage component, so as to facilitate the secure mounting of the data storage device inside the vehicle-mounted device, thereby improving the stability and shock resistance of the data storage device. Furthermore, recessed portions are provided on both sides of the first mounting bracket and / or the second mounting bracket that are relatively close to the housing, so that when the vehicle-mounted device collides and the energy is transferred to the data storage device, the recessed portions of the first mounting bracket and / or the second mounting bracket are broken first, thereby protecting the data storage device from being squeezed and deformed, thereby improving the anti-collision performance of the data storage device.

[0020] In one example of the present application, a waterproof material is used to fill the space between the storage component and the shell.

[0021] Compared with the existing technology, the technical effect achieved by adopting this technical solution is as follows: waterproof material is used to fill the space between the storage component and the shell to prevent moisture from entering the data storage device when the autonomous driving vehicle-mounted device is wading through water or encountering rain, thereby protecting the storage chip and other electronic components from water damage, thereby improving the safety of the data storage module during use.

[0022] In one example of the present application, the data storage device also includes: a data connector, which is integrally arranged with the cover body to establish a transmission channel for driving data between the data storage component and other vehicle-mounted equipment; wherein, when the cover body is sealed at the opening, one end of the data connector is connected to the other vehicle-mounted equipment, and the other end is connected to the storage component, and the waterproof material is filled from the end of the storage component away from the opening to the connection between the storage component and the data connector.

[0023] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: the data connector and the cover body are arranged integrally, so that when the cover body blocks the opening, when the autonomous driving vehicle-mounted device wades through water, moisture is prevented from entering the interior of the data storage device from the connection between the data connector and the cover body, thereby improving the waterproof performance of the data storage device, protecting the electronic components inside the data storage device from moisture, further improving the safety of the data storage device during use, and thereby extending the service life of the data storage device.

[0024] Furthermore, the waterproof material is filled from the end of the storage component away from the opening to the connection between the storage component and the data connector to prevent moisture from entering the data storage device after the shell and the cover are damaged in the event of an accident, causing damage to the storage component and the storage chip on the storage component, thereby improving the safety of the data storage device in the event of an accident and further extending the service life of the data storage device.

DETAILED DESCRIPTION

[0034] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0035] like Figures 1 to 5 As shown, the present application provides a data storage device 100 for an on-board device, and the data storage device 100 includes a storage component 110, a housing 120, and a cover 130. The storage component 110 is used to store driving data of the on-board device, and the housing 120 is used to accommodate the storage component 110, and the housing 120 is provided with an opening, and the cover 130 is sealed at the opening to prevent the storage component 110 from escaping from the housing 120; wherein the cover 130 is connected to the housing 120 in a snap-fit ​​manner.

[0036] This solution improves the convenience of the data storage device 100 during installation or removal, thereby improving the work efficiency of the operator.

[0037] Specifically, the present solution connects the cover body 130 and the shell body 120 in a snap-fit ​​manner, thereby avoiding the situation where the operator needs to perform complicated operations to disassemble and assemble the data storage device 100 when the data storage device 100 needs to be repaired, thereby improving the convenience of the data storage device 100 during installation or disassembly.

[0038] Furthermore, the present solution ensures the sealing performance between the cover 130 and the housing 120 through the tight fit of the snap connection, prevents the intrusion of impurities and moisture, and improves the protection effect of the data storage device 100.

[0039] Furthermore, the use of a snap-fit ​​structure simplifies the assembly and disassembly process between the cover 130 and the housing 120, making the operation simple and quick, and reducing maintenance costs. In addition, the snap-fit ​​method has good reusability, and can still maintain the original sealing effect after multiple disassembly and assembly; at the same time, the snap-fit ​​design also has excellent impact and shock resistance, which can protect the storage component 110 from damage during transportation and use.

[0040] This solution ensures the sealing performance between the cover 130 and the shell 120 through the tight fit of the buckle, prevents the intrusion of impurities and moisture, and improves the protection effect of the data storage device 100.

[0041] Furthermore, the use of a snap-fit ​​structure simplifies the assembly and disassembly process between the cover 130 and the housing 120, making the operation simple and quick, and reducing maintenance costs. In addition, the snap-fit ​​method has good reusability, and can still maintain the original sealing effect after multiple disassembly and assembly; at the same time, the snap-fit ​​design also has excellent impact and shock resistance, which can protect the storage component 110 from damage during transportation and use.

[0042] Further, such as Figure 4 and Figure 5 As shown, in any one of the embodiments provided in the present application, the cover body 130 is provided with an elastic component 131. When the cover body 130 is sealed at the opening, the elastic component 131 at least partially extends into the accommodating cavity 121 of the shell 120, and the elastic component 131 is buckled to the inner wall of the shell 120 near the storage component 110.

[0043] This solution ensures a tight fit between the cover body 130 and the shell 120 by providing an elastic component 131 on the cover body 130, thereby enhancing the sealing performance of the connection between the cover body 130 and the shell 120, preventing the intrusion of liquid, gas or dust, and protecting the safety and stability of the storage component 110.

[0044] Furthermore, the design of the elastic component 131 enables the cover 130 to adapt to deviations of different sizes during the capping process, and maintain a good sealing effect even within the manufacturing tolerance range of the housing 120 and the cover 130. Furthermore, the elastic component 131 is snapped into the interior of the housing 120, which helps to fix the position of the cover 130 and prevent the cover 130 from shifting due to external impact or vibration when an accident occurs, thereby protecting the storage component 110 placed inside the data storage 100 from damage.

[0045] Further, such as Figures 4 to 6 As shown, in any one of the embodiments provided in the present application, the elastic component 131 is provided with a first protrusion 131a, and the inner wall surface of the shell 120 is provided with a recessed structure 122. When the cover body 130 is sealed at the opening, the first protrusion 131a cooperates with the recessed structure 122.

[0046] Furthermore, the elastic component 131 is provided with a latching hole structure, and the inner wall surface of the shell 120 is provided with a second protrusion. When the cover body 130 is sealed at the opening, the latching hole structure cooperates with the second protrusion.

[0047] The convenience of the data storage device 100 during installation or removal is further improved, thereby improving the work efficiency of accident investigators.

[0048] Further, such as Figures 1 to 8As shown, in any embodiment provided in the present application, the data storage device 100 further includes a first mounting bracket 140 and a second mounting bracket 150. The first mounting bracket 140 is disposed on a side of the housing 120 away from the storage component 110 and extends outward relative to the housing 120, and the second mounting bracket 150 is disposed opposite to or offset from the first mounting bracket 140; and recessed portions 141 are disposed on both sides of the first mounting bracket 140 and / or the second mounting bracket 150 that are disposed opposite to each other near the housing 120. Thus, the anti-collision performance of the data storage device 100 is improved.

[0049] Specifically, the present solution provides a first mounting bracket 140 and a second mounting bracket 150 which are staggered on the side of the housing 120 away from the storage unit 110, so as to facilitate the data storage device 100 to be firmly mounted inside the vehicle-mounted device, thereby improving the stability and shock resistance of the data storage device 100. Furthermore, recessed portions 141 are provided on both sides of the first mounting bracket 140 and / or the second mounting bracket 150 which are relatively arranged near the housing 120, so that when the vehicle-mounted device collides and the energy is transferred to the data storage device 100, the recessed portions 141 of the first mounting bracket 140 and / or the second mounting bracket 150 are preferentially broken, thereby protecting the data storage device 100 from being squeezed and deformed, thereby improving the anti-collision performance of the data storage device 100.

[0050] For example, the data storage device 100 is installed at the installation position of the protective device 200, the first installation bracket 140 is provided with an elliptical screw hole 142, and the second installation bracket 150 is provided with a circular screw hole 151. During installation, the data storage device 100 is fixed at the installation position of the protective device 200 by passing a screw 300 through the elliptical screw hole 142 and a screw 300 through the circular screw hole 151.

[0051] Further, such as Figure 3 As shown, in any one of the embodiments provided in the present application, the space between the storage component 110 and the shell 120 is filled with waterproof material.

[0052] The space between the storage component 110 and the shell 120 is filled with waterproof material to prevent moisture from entering the data storage device 100 when the autonomous driving vehicle-mounted device is wading through water or encountering rain, thereby protecting the storage chip 111 and other electronic components from water damage, thereby improving the safety of the data storage module during use.

[0053] Further, such as Figure 1As shown, in any embodiment provided in the present application, the data storage device 100 further includes a data connector 160. The data connector 160 is integrally provided with the cover 130 to transfer the driving data stored in the storage component 110 to the storage device; wherein, when the cover 130 is sealed at the opening, one end of the data connector 160 is connected to the storage device, and the other end is connected to the storage component 110, and the waterproof material is filled from the end of the storage component 110 away from the opening to the connection between the storage component 110 and the data connector 160.

[0054] The data connector 160 is integrally arranged with the cover body 130, so that when the cover body 130 blocks the opening, when the autonomous driving vehicle-mounted device wades through water, moisture is prevented from entering the interior of the data storage device 100 through the connection between the data connector 160 and the cover body 130, thereby improving the waterproof performance of the data storage device 100, protecting the electronic components inside the data storage device 100 from moisture, further improving the safety of the data storage device 100 during use, and thus extending the service life of the data storage device 100.

[0055] Furthermore, the waterproof material is filled from the end of the storage component 110 away from the opening to the connection between the storage component 110 and the data connector 160 to prevent moisture from entering the data storage device 100 after the shell 120 and the cover 130 are damaged in the event of an accident, thereby causing damage to the storage component 110 and the storage chip 111 on the storage component 110, thereby improving the safety of the data storage device 100 in the event of an accident and further extending the service life of the data storage device 100.

[0056] For example, the data connector 160 provided in the embodiment of the present application is a data connection cable with a double-headed type-c interface. When the outer interface exposed on the cover body 130 away from the storage component 110 is damaged, it is only necessary to replace a new double-headed type-c data connection cable to export the driving data in the storage component 110, thereby improving the convenience of data export.

[0057] Furthermore, in any embodiment provided in the present application, the shell 120 is made of plastic, and the wall surface of the shell 120 away from the storage component 110 is provided with a fireproof coating, and the cover 130 is made of plastic, and the wall surface of the cover 130 away from the storage component 110 is provided with a fireproof coating.

[0058] This solution improves the fireproof performance of the data storage 100, so that the data storage 100 can maintain the integrity of the internal components of the data storage 100 in the event of a fire, thereby reducing the damage rate of the data storage 100 in a fire situation, and further reducing the maintenance cost and replacement cost of the data storage 100.

[0059] Furthermore, in any one of the embodiments provided in the present application, the fire retardant coating is an intumescent fire retardant coating.

[0060] The intumescent fire-retardant coating will undergo a chemical reaction when subjected to high temperature to form a foamy carbonized layer; the expanded carbonized layer can prevent flames and heat from further transferring to the shell 120 or the cover 130, thereby isolating the fire source, extending the fire resistance time of the shell 120 or the cover 130, and further improving the fire resistance of the data storage device 100.

[0061] For example, the intumescent fire retardant coating of the present application may be composed of ammonium polyphosphate and melamine formaldehyde resin, wherein the ammonium polyphosphate serves as an acid source and the melamine formaldehyde resin serves as a carbon source, and the combination of the two can form an intumescent carbonized layer at high temperature.

[0062] For example again, the fire retardant coating in the present application can also be any one of a non-expanding fire retardant coating, an inorganic hydroxide fire retardant coating, an organic silicon resin fire retardant coating, and a composite fire retardant coating. Specifically, the non-expanding fire retardant coating can be a slag wool-based fire retardant coating or a silicate fire retardant coating; the inorganic hydroxide fire retardant coating can be an aluminum hydroxide fire retardant coating or a magnesium hydroxide fire retardant coating; the organic silicon resin fire retardant coating can be an organic silicon fire retardant coating; and the composite fire retardant coating can be a polymer cement-based fire retardant coating.

[0063] On the other hand, the present application also provides a vehicle-mounted device, which includes a data storage device 100 as described in any of the above technical solutions.

[0064] Since a vehicle-mounted device in the present technical solution includes the data storage device 100 as described in any of the above technical solutions, the present technical solution includes the beneficial effects of any of the above technical solutions, which will not be repeated here.

[0065] It should be noted that in actual product and technical practice, the vehicle-mounted device described in the above embodiments of the present application may be an autonomous driving data recording device or other vehicle-mounted equipment. In one example, the autonomous driving data recording device may be an autonomous driving data recording system (DSSAD) or other equipment with autonomous driving data recording function, such as an event data recording system (EDR), a digital video recorder (DVR), a driving recorder, a car black box or other vehicle-mounted equipment that may appear in the future, which is not limited by the present application.

[0066] Although the present application is disclosed as above, the present application is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present application. Therefore, the protection scope of the present application shall be subject to the scope defined by the claims.
