Detailed Description

While the electronic device of one embodiment of the present invention, such as a heads-up display device, in other embodiments, the electronic device may also be a meter or infotainment system.

The head-up display device includes a housing and a PCB disposed within the housing.

As shown in fig. 1 and 2, the housing includes a first housing (a rear case 1) and a second housing (an upper cover 2), and a cover glass 3 is further disposed on the housings.

As shown in fig. 3, the rear shell 1 is engaged with the upper cover 2 through the C-shaped engaging member 4, and a gap 5 is formed between corresponding surfaces of the rear shell 1 and the upper cover 2, the gap 5 prevents abrasion during a vibration process, and the elastic constraint provided by the C-shaped engaging member 4 prevents the rear shell 1 and the upper cover 2 from being fitted loosely.

The outer side of the rear shell 1 is provided with a first groove 11, the outer side of the upper cover 2 is provided with a second groove 21 at a corresponding position, two ends of the C-shaped clamping piece 4 are respectively embedded into the first groove 11 and the second groove 21, and the rear shell 1 and the upper cover 2 are clamped through the C-shaped clamping piece 4.

The C-shaped engaging member 4 has a belt-like structure.

As shown in fig. 4, the both ends of the C-shaped engaging piece 4 are provided with outward

opening arcs

41, 42, and the

arcs

41, 42 have an arc degree of 30 ° or more and 40 ° or less. The

arcs

41 and 42 are embedded in the first groove 11 and the second groove 21, so that the abrasion of the end part of the C-shaped clamping piece 4 to the first groove 11 and the second groove 21 during vibration is avoided.

The rear shell 1 is internally provided with a first protrusion 12, the upper cover 2 is internally provided with a first concave part 22 corresponding to the first protrusion 12, and the end part of the first protrusion 12 is contacted with the bottom surface of the first concave part 22 to ensure that the gap 5 is within a set range.

In other embodiments, a second recess may be provided in the rear housing, a second protrusion may be provided in the upper cover at a position corresponding to the recess, and an end of the second protrusion contacts with a bottom surface of the second recess; the rear shell and the upper cover are provided with protrusions, namely a third protrusion and a fourth protrusion, the third protrusion is in contact with the fourth protrusion, and a set gap is formed between corresponding surfaces of the rear shell and the upper cover.

The set range is, for example, 0.5 to 1.2 mm. In the manufacturing process, the length of the protrusion and the position of the bottom surface of the recess can be adjusted accordingly by adjusting the mold of the rear housing 1 or the mold of the upper cover 2 to ensure that the gap 5 is within the set range, in this embodiment, the specifically set gap 5 is 0.8mm, while the gap 5 between the manufactured rear housing 1 and the upper cover 2 is 0.4mm, 0.2mm can be milled at the position of the mold of the rear housing 1 corresponding to the first protrusion 12, and 0.2mm can be milled at the position of the mold of the upper cover 2 corresponding to the first recess 22, so that the gap 5 between the two is 0.8 mm. If the gap 5 between the manufactured rear shell 1 and the upper cover 2 is larger than 0.8mm, the gap can be adjusted to 0.8mm by overlaying at the corresponding position of the die.

The first groove 11 is arc-shaped and/or the second groove 21 is arc-shaped.

The arc-shaped groove facilitates the sliding in or the exiting of the

arcs

41 and 42, so that the C-shaped clamping piece 4 is easier to disassemble and assemble.

When the device is installed, the rear shell 1 is aligned with the upper cover 2, and the C-shaped clamping piece 4 is pushed in to enable the

arcs

41 and 42 to be embedded into the first groove 11 and the second groove 21; when disassembling, only the C-shaped engaging member 4 needs to be pulled out.
