Description

Technical Field

[0001] This utility model relates to the field of power adapter technology, and in particular to a power adapter for a dashcam and a vehicle. Background Technology

[0002] A dashcam power adapter is a power conversion device specifically designed for dashcams. Its core function is to convert external power (such as the vehicle's power supply) into a stable DC power supply that the dashcam can directly use, ensuring continuous and safe operation of the device. Currently, most dashcam power adapters on the market have their input and output power cables integrated and fixedly connected to the main body of the device. This design has some drawbacks, such as:

[0003] (1) Cable length cannot be adapted to diverse vehicle models: Different car brands, models, and internal structures vary greatly, and the installation location requires different power cable lengths. For example, the compact cabin space of small cars makes long cables prone to tangling and mess; while large cars or models with special layouts require even longer cables to meet the wiring distance. Existing integrated cables cannot be lengthened, forcing users to accept cables that are too long or too short, which seriously affects the convenience of installation.

[0004] (2) The aesthetics of the wiring are hard to guarantee: Since the length of the wires cannot be adjusted, users often need to forcibly bend or bundle the excess wires when loading the vehicle, which not only affects the cleanliness of the vehicle, but may also cause the insulation layer to wear due to excessive compression of the wires, posing a safety hazard.

[0005] (3) High maintenance cost and complicated operation: When the power adapter is damaged, the user needs to replace the entire device, including the original cable, which is still usable, resulting in a waste of resources. Utility Model Content

[0029] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0030] The dash cam power adapter is a power conversion device designed specifically for dash cams. Its core function is to convert external power (such as vehicle power) into a stable DC power supply that the dash cam can use directly, so as to ensure the continuous and safe operation of the device. According to the inventor, the dash cam power supplies commonly found on the market have the following problems: (1) The input / output power cords are integrated with the device and the length of the cord cannot be changed. When installed on a vehicle, the length requirements of the cord vary greatly depending on the vehicle brand, model and size. The inability to change the length of the cord will affect the convenience of installation and the aesthetics of the wiring. (2) It does not have an automatic shutdown / sleep voltage adjustment function.

[0031] Therefore, please refer to Figures 1 to 5 This utility model discloses a power adapter for a dashcam, comprising a housing and a circuit board, an input device, and an output device disposed within the housing. The input device and output device are both connected to the circuit board. The input device is located at one end of the housing and has an input interface extending from that end. The output device is located at the other end of the housing and has an output interface extending from that end. The input and output interfaces are for detachable connection to a power cord. In practical applications, the power adapter can be detachably connected to the power cord at one end or at both ends. Depending on its function, the power cord can be divided into an input power cord and an output power cord.

[0032] As described above, the beneficial effects of this utility model are as follows: This utility model provides a dedicated power adapter for a car dashcam with detachable and replaceable input and output power cables. The power adapter housing 1 has pluggable input interfaces 21 and output interfaces 31 at both ends, which are detachably connected to the power cables, allowing for quick replacement of the input and output power cables. In practical applications, users can select different lengths of input / output power cables according to vehicle type (e.g., sedan, SUV, truck), adapting to diverse vehicle models and solving the installation problems of traditional integrated cables being too long and tangled or too short. When the power adapter malfunctions, there is no need to replace the cable; only the power adapter needs to be replaced, avoiding resource waste and reducing maintenance costs. Furthermore, when installing this power adapter, the cable length can be selected according to actual needs, reducing excess cable bending or bundling, improving wiring aesthetics, and reducing the risk of insulation wear.

[0033] Furthermore, the power adapter described in this utility model also includes a DC-DC converter, which is disposed on the circuit board and is used to step down and convert the high voltage input from the input interface to a preset low voltage.

[0034] Furthermore, in the power adapter described in this utility model, the housing 1 includes an upper housing 11 and a lower housing 14, and the upper housing 11 and the lower housing 14 are detachably connected.

[0035] As described above, the housing 1 is divided into two detachable parts, which facilitates assembly and maintenance, and makes it convenient for the installation, debugging and troubleshooting of the internal circuit board 4.

[0036] Furthermore, the power adapter described in this utility model also includes a circuit board 4, which is disposed in the inner cavity of the housing 1.

[0037] Furthermore, in the power adapter described in this utility model, the lower housing 14 is provided with a plurality of support members 15, and the circuit board 4 is disposed on the support members 15.

[0038] In practical applications, there can be two support members 15. The two support members 15 are respectively set at both ends inside the lower housing 14. The circuit board 4 is supported by the two support members 15, which helps to ensure the stability of the circuit board 4 inside the lower housing 14.

[0039] Furthermore, in the power adapter described in this utility model, the lower housing 14 is provided with a plurality of locking blocks 16, and the circuit board 4 is provided with a plurality of locking slots 12 for locking the locking blocks 16.

[0040] In practical applications, multiple locking blocks 16 are provided along the length of the lower housing 14. These locking blocks 16 can form a locking structure with the bayonet 12 to ensure the stable installation of the circuit board 4, prevent it from loosening or falling off, and improve product reliability.

[0041] Furthermore, the power adapter described in this utility model also includes a low voltage protection value adjustment device 5, which is disposed on the housing 1.

[0042] Furthermore, in the power adapter described in this utility model, the low voltage protection value adjustment device 5 includes a connector 51 and a toggle member 52. The connector 51 is disposed on the circuit board 4, and the toggle member 52 is disposed on the housing 1. The toggle member 52 is slidably connected to the connector 51.

[0043] Furthermore, in the power adapter described in this utility model, a guide groove 17 is provided on the outer side wall of the housing 1, and a sliding hole 18 communicating with the inner cavity of the housing 1 is provided at the bottom of the guide groove 17. The actuating member includes a first slider 53 and a second slider 54 connected to each other. The first slider 53 is slidably disposed in the guide groove 17, and the second slider 54 passes through the sliding hole 18 and is slidably connected to the connector 51.

[0044] In practical applications, corresponding sliding contacts can be set on the second slider 54, and multiple fixed contacts can be set on the connector 51. When the second slider moves to a certain position, the sliding contacts are in close contact with the fixed contacts of that position to form a conductive path, thereby realizing the adjustment of the position.

[0045] As described above, the outer side of the housing 1 is provided with a guide groove 17, and the toggle member 52 is slidably connected to the connector 51, thus forming a sliding toggle switch structure. In actual use, the user switches the low voltage protection setting level by sliding the toggle member 52, allowing the user to select an appropriate low voltage protection setting value according to the usage of their car battery. This maximizes the use of the car battery power while avoiding draining the battery and preventing the car from failing to start next time. After the user selects an appropriate low voltage protection setting value by sliding the toggle member 52, the circuit board monitors the car battery voltage. If the car battery voltage is lower than the appropriate low voltage protection setting value, the power adapter will turn off the working voltage output to the dashcam after a preset time (e.g., 90 seconds), and the Bluetooth module's communication function will be turned off, entering a sleep or shutdown state. This ensures that the car battery power is not excessively used, preventing the car from failing to start next time.

[0046] Furthermore, in the power adapter described in this utility model, the upper housing 11 is provided with a plurality of heat dissipation holes 13.

[0047] As can be seen from the above description, the upper housing 11 has multiple heat dissipation holes 13 to accelerate the heat dissipation of internal components during operation and improve safety.

[0048] Accordingly, the present invention also provides a vehicle, the vehicle including an input power device (such as a vehicle power supply), a driving recorder, an input power cord, an output power cord, and a power adapter as described above, wherein the input power device is detachably connected to the input power cord, the driving recorder is detachably connected to the output power cord, and the power adapter is detachably connected to the input power cord and / or the output power cord.

[0049] As described above, the detachable cable, in conjunction with the power adapter, allows for quick replacement of the input and / or output power cables. In practical applications, users can select different lengths of input / output power cables based on vehicle type (e.g., sedans, SUVs, trucks), adapting to diverse vehicle models and solving the installation problems of traditional integrated cables being too long and tangled or too short. When the power adapter fails, only the power adapter needs to be replaced, eliminating the need to replace the cable and avoiding resource waste and reducing maintenance costs. Furthermore, when installing this power adapter, the cable length can be selected according to actual needs, reducing excess cable bending or bundling, improving wiring aesthetics, and reducing the risk of insulation wear.

[0050] Please refer to Figures 1 to 5 A preferred embodiment of this utility model is a power adapter for a vehicle dashcam. The power adapter includes a housing 1, an input device 2, and an output device 3. The input device 2 is located at one end of the housing 1 and has an input interface 21 (i.e., a high-voltage input port). The input interface 21 is detachably connected to an input power cord. The input interface 21 and the input power cord are used to receive a 12V~30V high-voltage input voltage from the vehicle power supply. The output device 3 is located at the other end of the housing 1 and has an output interface 31 (i.e., a low-voltage output port). The output interface 31 is detachably connected to an output power cord. The power adapter can step down the 12V~30V high-voltage input from the vehicle power supply to a 5V output working voltage, so as to deliver the 5V output working voltage to the vehicle dashcam for power supply through the output interface 31 and the output power cord.

[0051] In this embodiment, as Figure 3 As shown, the housing 1 includes an upper housing 11 and a lower housing 14, which are detachably connected. The upper housing 11 and the lower housing 14 together form an inner cavity, in which the circuit board 4 is disposed. To ensure the stability and security of the circuit board 4 within the inner cavity, this embodiment provides multiple support members 15 within the lower housing 14, on which the circuit board 4 is mounted. Additionally, this embodiment provides multiple locking blocks 16 within the lower housing 14, and the circuit board 4 has multiple locking slots 12 for engaging the locking blocks 16, thus securing it in place. Furthermore, the upper housing 11 also has multiple heat dissipation holes 13 for heat dissipation.

[0052] In this embodiment, as Figure 2 , Figure 3 as well as Figure 5As shown, the power adapter also includes a low voltage protection value adjustment device 5, which includes a connector 51 and a toggle member 52. The connector 51 is disposed on the circuit board 4, and the toggle member 52 is disposed on the housing 1. The toggle member 52 is slidably connected to the connector 51. Specifically, a guide groove 17 is provided on the outer side wall of the housing 1, and a sliding hole 18 communicating with the inner cavity of the housing 1 is provided at the bottom of the guide groove 17. The toggle member includes a first slider 53 and a second slider 54 connected to each other. The first slider 53 is slidably disposed in the guide groove 17, and the second slider 54 passes through the sliding hole 18 and is slidably connected to the connector 51.

[0053] In summary, the power adapter and vehicle provided by this utility model: (1) Both the input power line and the output power line are pluggable, which makes it convenient for users to select different lengths of wire for connection according to the style and size of their car, and makes the wiring convenient and aesthetically pleasing when installing the vehicle. (2) Multiple (e.g., four) automatic shutdown voltage selections make it convenient for users to select appropriate low voltage protection settings according to the battery usage of their car, which can maximize the use of the car battery power supply and avoid draining the battery power so that the car cannot be started next time. In addition, by setting the pluggable input interface 21 and output interface 31, when the step-down box is damaged, it is not necessary to replace the wires, but only to replace the step-down box, avoiding rewiring.
