Description

Technical Field

[0001] This utility model relates to charging equipment, and more particularly to a vehicle-mounted charger housing and a vehicle-mounted charger equipped with a display screen assembly. Background Technology

[0002] Currently, the LED panel (display screen) and USB interface of the vehicle charger need to be exposed outside the forklift, so there are specified height restrictions for the LED panel and USB interface in the charger.

[0003] There are currently two solutions. One solution is to have two support columns inside the housing for the LED, which serve as guides during the installation of the LED board. However, this structure cannot accurately position the LED installation location, and the position of the LED board needs to be manually adjusted during installation, which is inconvenient. The mold shape of this structure is complex and requires machining to complete.

[0004] Another design involves creating a slanted groove inside the housing for the LED and USB ports. This design requires a larger space, taking up the area of ​​the heat sink on the back of the housing and reducing the housing's heat dissipation capacity. Furthermore, this design makes it difficult to install the LED and USB ports, requiring a person to reach into the groove for installation and manually adjust the USB port's orientation.

[0005] The current on-board chargers have relatively thick casings. This is because the installation space for each component and the heat sink do not interfere with each other. For example, an on-board charger with an external wake-up function, which has the application number 202210742793.9, requires a recessed design at the bottom of the casing to reduce the thickness of the casing. Utility Model Content

[0006] This utility model addresses the shortcomings of existing technologies by providing a vehicle-mounted charger housing with a display screen assembly and a vehicle-mounted charger.

[0007] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method:

[0008] The vehicle charger housing with a display screen assembly includes a housing and a display screen assembly mounted on the housing. The display screen assembly includes a circuit board and a display screen. The housing has a first mounting groove, and the bottom of the first mounting groove has a recessed second mounting groove. Both ends of the bottom of the second mounting groove have bosses with horizontal end faces. The circuit board is installed in the second mounting groove and supported on the bosses. The circuit board can move along the surface of the bosses and mount the display screen on the side wall of the housing.

[0009] Preferably, the bottom of the first mounting groove is provided with a groove for fingers to pass through, and the groove communicates with the second mounting groove.

[0033] The following is in conjunction with the appendix Figure 1-5 The present invention will be further described in detail with reference to the embodiments.

[0034] Example 1

[0035] The vehicle charger housing with a display screen assembly includes a housing 1 and a display screen assembly mounted on the housing 1. The display screen assembly includes a circuit board 2 and a display screen 3, with the display screen 3 fixed to the circuit board 2. The housing 1 has a first mounting groove 11, and a recessed second mounting groove 12 at the bottom of the first mounting groove 11. Both ends of the bottom of the second mounting groove 12 have protrusions 13, with the end faces of the protrusions 13 being horizontal. The circuit board 2 is mounted in the second mounting groove 12 and supported on the protrusions 13. The circuit board 2 can move along the platform of the protrusions 13 to mount the display screen 3 onto the side wall of the housing 1. The protrusions 13 not only support the circuit board 2 but also act as guides, facilitating the movement of the circuit board 2 along its platform to mount the display screen onto the housing 1.

[0036] The bottom of the first mounting slot 11 is provided with a groove 14 for fingers to pass through. The groove 14 is connected to the second mounting slot 12. The groove 14 provides mounting space for fingers, thereby facilitating people to assemble and disassemble the display screen assembly.

[0037] The depth of the groove 14 is less than the depth of the second mounting groove 12. A number of heat sinks are integrally formed on the outer end face of the housing 1. The small depth of the groove 14 can reduce the space occupied by the heat sink and increase the heat dissipation area of ​​the heat sink.

[0038] The second mounting slot 12 includes a mounting area 121 and a positioning area 122. The width of the display screen 3 is a, the width of the mounting area 121 is b, and the width of the positioning area 122 is c, where b > a and b > c. The display screen 3 is positioned and mounted on the positioning area 122. The mounting area 121 provides a large installation space, making it convenient for operators to install the display screen assembly.

[0039] A USB connector 4 is installed on the side wall of the housing 1. A third mounting slot 15 is provided at the bottom of the first mounting slot 11. The USB connector 4 is fastened to the side wall of the housing 1 through the third mounting slot 15. The third mounting slot 15 provides a dedicated installation space for the USB connector 4, making it easy to install and remove the USB connector 4. At the same time, the USB connector 4 is installed in a recessed manner through the third mounting slot, which reduces the thickness of the housing 1, reduces material usage, and lowers costs.

[0040] Example 2

[0041] Example 2 is basically the same as Example 1, except that the third mounting groove 15 is a stepped groove. The end of the third mounting groove 15 closest to the side wall of the housing 1 is the large end area 151, and the end of the third mounting groove 15 away from the side wall of the housing 1 is the small end area 152. The depth of the large end area 151 is greater than the depth of the small end area 152. The stepped third mounting groove 15 can reduce the space occupied by the heat sink and increase the heat dissipation area of ​​the heat sink.

[0042] The width of the large head area 151 is d, and the width of the small head area 152 is e. Since d > e, it can reduce the space occupied by the heat sink and increase the heat dissipation area of ​​the heat sink.

[0043] The bottom of both the large head area 151 and the small head area 152 is curved, which can reduce the space occupied by the heat sink and increase the heat dissipation area of ​​the heat sink.
