The utility model provides a car key, including the first casing and second casing of PCB board and holding PCB board, first casing has along assembling the seal structure that the direction is overlapped each other with the second casing, is provided with the sealing member between the seal structure to form airtight space. The utility model provides a car key adopts the seal structure who overlaps each other, and the sealing member is to the reaction force of sealing load production to on not acting on the installation direction of first casing and second casing, consequently can not exert an influence to the clearance between first casing and the second casing, guarantee that first casing and second casing block are firm, because sealing member and first casing adopt double -shot moulding integrated into one piece, button and sealing member integrated into one piece have reduced the quantity of car key's part, can reduce the frock like this, have also reduced the expense of equipment simultaneously to reduce car key's manufacturing cost.

Description

A kind of automobile key

Technical field

The utility model relates to automobile manufacturing field, is specifically related to automobile key.

Background technology

As shown in Figure 1; automobile key generally includes button 1, upper cover 2, silicagel pad 3, pcb board 4 and lower cover 5; pcb board 4 is arranged in the space that upper cover 2 and lower cover 5 formed; the edge of silicagel pad 3 is fitted between upper cover 2 and lower cover 5 contact surface; enter in the space that upper cover 2 and lower cover 5 formed, to protect pcb board 4 for anti-sealing.

There is following problem in this structure:

Silicagel pad 3 can produce reaction force to sealing load, acts on the gap between upper cover 2 and lower cover 5, makes the gap between upper cover 2 and lower cover 5 uneven, cause the engaging between upper cover 2 with lower cover 5 insecure, easily cause the inefficacy of fall-down test.

Summary of the invention

For problems of the prior art, problem to be solved in the utility model is to provide a kind of automobile key, adopts overlapped hermetically-sealed construction, the reaction force that seal produces sealing load, will upper cover be caused to engage with lower cover insecure.

The utility model provides a kind of automobile key, comprise the first housing and second housing of pcb board and accommodating pcb board, first housing and the second housing have along the overlapped hermetically-sealed construction of assembly direction, are provided with seal between hermetically-sealed construction, to form confined space.

Further, seal and the first housing adopt double-shot moulding one-body molded.

Further, automobile key also comprises button, button and seal one-body molded.

Further, the position that seal is between described hermetically-sealed construction is provided with arc convex, can reach better waterproof effect.

Compared with prior art, the automobile key that the utility model provides has the following advantages:

(1) overlapped hermetically-sealed construction is adopted, the reaction force that seal produces sealing load, do not act on the installation direction of the first housing and the second housing, therefore the gap between the first housing and the second housing can not be had an impact, ensure that the first housing engages firmly with the second housing;

(2) because seal and the first housing adopt double-shot moulding one-body molded, button and seal one-body molded, decrease the quantity of the parts of automobile key, can frock be reduced like this, decrease the expense of assembling simultaneously, thus reduce the manufacturing cost of automobile key.

Detailed description of the invention

As shown in Figure 2 and Figure 3, the automobile key of an embodiment of the present utility model, comprises pcb board 14, the accommodating pcb board 14 in the space that the first housing and the second housing are formed, and in the present embodiment, the first housing is upper cover 12, and the second housing is lower cover 15.

As shown in Figure 4, upper cover 12 and lower cover 15 have along the overlapped hermetically-sealed construction 121,151 of assembly direction, are provided with seal 13, to form the confined space of accommodating pcb board 14 between hermetically-sealed construction 121,151.

Adopt overlapped hermetically-sealed construction 121,151, the hermetically-sealed construction 121 of reaction force perpendicular to upper cover 12 that seal 13 pairs of sealing loads produce and the hermetically-sealed construction 151 of lower cover 15, do not act on upper cover 12 with on the installation direction of lower cover 15, therefore the gap between upper cover 12 and lower cover 15 can not be had an impact, ensure that upper cover 12 engages firmly with lower cover 15.

In the present embodiment, seal 13 and upper cover 12 adopt double-shot moulding one-body molded, and wherein upper cover 12 adopts glass-fiber-reinforced polyamide to make, and other ebonite materials also can be adopted to make, such as engineering plastics; Seal 13 adopts TPUE (Thermoplasticpolyurethane, TPU) or silica gel to make, and other flexible glue materials also can be adopted to make, and the utility model is not restricted this.

Seal 13 is one-body molded with upper cover 12, decreases the quantity of the parts of automobile key, can reduce frock like this, decrease the expense of assembling simultaneously, thus reduces the manufacturing cost of automobile key; Compared with embedding with independent seal in addition between upper cover 12 and the hermetically-sealed construction 121,151 of lower cover 15, convenient with the assembling of lower cover 15.

Certainly, seal 13 also can be independent seal, and namely seal 13 is not integrated with upper cover 12.

As shown in Figure 4, seal 13 is in the position between hermetically-sealed construction 121,151, is provided with arc convex 131, can reach better waterproof effect like this.Certain projection also can be arranged on hermetically-sealed construction 151.

Automobile key of the prior art, as shown in Figure 1, button 1, upper cover 2 need at least three to overlap frock with silicagel pad 3, also need the expense of assembling, cause manufacturing cost higher.

In the present embodiment, automobile key comprises button 11, button 11 adopts flexible glue to make, one-body molded with seal 13, as shown in Figure 5, namely the button 1 of automobile key in prior art, upper cover 2 are combined into parts with silicagel pad 3, decrease the parts of automobile key, reduce the manufacturing cost of automobile key.The button 11 adopting flexible glue to make, has good elasticity, can meet the requirement of button operation and the requirement of operating handle.Further reduce the quantity of the parts of automobile key in addition, reduce the manufacturing cost of automobile key.

Can certainly use button of the prior art, button is not integrated with seal 13, namely the upper cover 2 of automobile key in prior art (as shown in Figure 1) is combined into parts with silicagel pad 3.

In the present embodiment, the hermetically-sealed construction of upper cover 12 is positioned at the outside of the hermetically-sealed construction 151 of lower cover 15, adopts such structure, the top edge of the hermetically-sealed construction 151 of lower cover 15 directly can be utilized to support pcb board 14, simplify the structure of lower cover 15.

As shown in Figure 3, upper cover 12 is provided with buckle structure 122, lower cover 15 is provided with buckle structure 152, buckle structure 122,152 is arranged in pairs.In the present embodiment, arrange five pairs of buckle structures 122,152 altogether, upper cover 12 and lower cover 15 are fastened togather by buckle structure 122,152.

Although the utility model discloses as above with preferred embodiment, the utility model is not defined in this.Any those skilled in the art, not departing from the various change and amendment done in spirit and scope of the present utility model, all should include in protection domain of the present utility model, therefore protection domain of the present utility model should be as the criterion with claim limited range.
