Abstract
The invention discloses a cover board structure of a vehicle terminal shell. The cover board structure comprises a lower cover body and an upper cover body, wherein the upper cover body is arranged in the lower cover body; blocking components are arranged on the connected part of the lower cover body and the upper cover body; a buffer structure is connected between the clamping components; and a circle of printed circuit board (PCB) fixing grooves is formed in the upper cover body, so that the damaged degree of the PCB can be retarded, and the service life of a vehicle terminal is prolonged.
Description
Technical field
The present invention relates to car-mounted terminal field, particularly, relate to a kind of covering plate structure of car-mounted terminal housing.
Background technology
Along with increasing year by year of automobile quantity, car-mounted terminal is more and more universal, such as: drive recorder, navigation etc.The inside of car-mounted terminal is provided with pcb board, and pcb board is fixed in casing by the structure such as screw, fixed leg, and its casing comprises lower house and the upper shell for sealing lower house, and pcb board is fixed in lower house.Lower house is by adhesion or directly place with on car.Car-mounted terminal adopts this kind of structure, and vehicle travels on the road of jolting, and car-mounted terminal can jolt along with vehicle or collide with up and down.Pcb board in car-mounted terminal sensitive for damages in the process of jolting, makes the life-span of car-mounted terminal be affected.
Summary of the invention
The present invention provides a kind of covering plate structure of car-mounted terminal housing in order to solve the problems of the technologies described above, it can slow down the pcb board extent of damage, extends the useful life of car-mounted terminal.
The present invention's adopted technical scheme that solves the problem is:
A kind of covering plate structure of car-mounted terminal housing, comprise lower cover and the upper cover body being positioned at lower cover, described lower cover and the connecting portion of upper cover body are provided with engaging part, are connected with buffer structure between described engaging part, are provided with a circle pcb board holddown groove in described upper cover body.
The present invention improves on the basis of existing technology, pcb board is fixed in upper cover body, interfixed by engaging part between upper cover body and lower cover, and buffer unit is set between engaging part, vehicle is in the process of jolting, and due to the effect of buffer structure, the Oscillation Amplitude of upper cover body is less than the degree that vehicle jolts, to reduce the pcb board extent of damage, extend the useful life of car-mounted terminal.
As preferably, described engaging part comprises the first fastener be arranged on lower cover inwall and the second fastener be arranged on upper cover body outer wall, and described buffer structure is arranged between the first fastener and the second fastener and between the second fastener and lower cover.Utilize the cooperation between the first fastener and the second fastener, make upper cover body can relative to lower cover relative motion in vehicle jolts process, with buffer structure coordinate the object reaching and slow down pcb board and jolt, namely slow down the pcb board extent of damage, extend useful life of car-mounted terminal.
Further, in order to ensure the stability of upper cover body and lower cover, the first described fastener and the outer wall of upper cover body are fitted, and the second described fastener and the inwall of lower cover are fitted.
Further, the first described fastener is collar.
Further, the second described fastener is collar.
As preferably, described buffer structure is spring.
To sum up, the invention has the beneficial effects as follows:
1, pcb board is fixed in upper cover body by the present invention, interfixed by engaging part between upper cover body and lower cover, and buffer unit is set between engaging part, vehicle is in the process of jolting, due to the effect of buffer structure, the Oscillation Amplitude of upper cover body is less than the degree that vehicle jolts, and to reduce the pcb board extent of damage, extends the useful life of car-mounted terminal.
2, structure of the present invention is simple, is easy to make.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Mark and corresponding parts title in accompanying drawing: 1, lower cover; 11, the first fastener; 2, upper cover body; 21, pcb board holddown groove; 22, the second fastener.
Embodiment
Below in conjunction with embodiment and accompanying drawing, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Embodiment 1:
The covering plate structure of a kind of car-mounted terminal housing as shown in Figure 1, comprise lower cover 1 and the upper cover body 2 being positioned at lower cover 1, described lower cover 1 and the connecting portion of upper cover body 2 are provided with engaging part, be connected with buffer structure between described engaging part, in described upper cover body 2, be provided with a circle pcb board holddown groove 21.
Embodiment 2:
The covering plate structure of a kind of car-mounted terminal housing as shown in Figure 1, the present embodiment is optimized on the basis of above-described embodiment, namely described engaging part comprises the first fastener 11 be arranged on lower cover 1 inwall and the second fastener 22 be arranged on upper cover body 2 outer wall, and described buffer structure is arranged between the first fastener 11 and the second fastener 22 and between the second fastener 22 and lower cover 1.
The first described fastener 11 is fitted with the outer wall of upper cover body 2, and the second described fastener 22 is fitted with the inwall of lower cover 1.Adopt this structure, upper cover body 2 only can be moved up and down relative to lower cover, avoid its double swerve, strengthen the stability of its structure.
The first described fastener 11 is collar.
The second described fastener 22 is collar.
First fastener 11 and the second fastener 22 can adopt fixture block, arrange connection for the ease of buffer structure, preferably adopt collar.
Described buffer structure is spring.Adopt spring, its buffering effect is good.
As mentioned above, the present invention can be realized preferably.
