Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.It is understood that herein
Described specific embodiment is used only for explaining the utility model, rather than the restriction to the utility model.It further needs exist for
It is bright, part relevant to the utility model is illustrated only for ease of description, in attached drawing rather than entire infrastructure.
Fig. 1 is a kind of separate structure schematic diagram of human-computer interaction device provided by the embodiment of the utility model, and Fig. 2 is this reality
With a kind of schematic diagram of internal structure for plastic box body that new embodiment provides, the present embodiment is applicable in elevator control dial
The situation of PCBA board unprotect and anti-static device etc., the human-computer interaction device specifically include control handwheel panel 110, plastic box body
120, printed circuit-board assembly PCBA board 130 and control handwheel box component 140.
PCBA board 130 is fixed in plastic box body 120.
Control handwheel panel 110 and control handwheel box component 140 cooperatively form accommodating space 141, and plastic box body 120 is placed in appearance
In 141 between emptying.
Specifically, as shown in Fig. 2, there are many ways to PCBA board 130 is fixed in plastic box body 120, such as can lead to
It crosses nut to fix, or be fixed by configuring the fastener to match with 120 size of plastic box body.The shape of plastic box body 120
Shape can there are many, such as cuboid, square, the shape of plastic box body 120 and the shape of PCBA board be similar.Plastic box body
120 volume and the volume matched of PCBA board 130.Specifically, the volume of plastic box body 120 can accommodate PCBA board 130, and not
The volume of PCBA board 130 can be excessively greater than.Under normal circumstances, the volume of plastic box body 120 can be easily installed PCBA board 130 i.e.
It can.Before transportation, PCBA board 130 is fixed in plastic box body 120.The material of plastic box body 120 be made of plastic cement,
Therefore there is plastic box body 120 insulating properties to rise so as to avoid extraneous static from being transferred in PCBA board 130 to PCBA board 130
To the effect of antistatic.Therefore it no longer needs static bag to pack PCBA board 130 during transporting PCBA board 130, avoids
When installing PCBA board 130 remove this installation steps of static bag, and solve static bag waste and static bag caused by dirt
The problem of dye.Plastic cement also has plasticity and mobility, therefore plastic box body 120 can absorb vibration, and protection PCBA board 130 is exempted from
By extraneous collision.
Control handwheel panel 110 and control handwheel box component 140 cooperatively form accommodating space 141, and the four of control handwheel panel 110
The polygon size that the surrounding side of the polygon that all sides are formed and control handwheel box component 140 is formed is of substantially equal, shape
It is identical.It under normal circumstances, can be rectangle or trapezoidal etc..Buckle, control handwheel are provided on the surrounding side of control handwheel panel 110

Four through-holes of plastic box body 120 form the through-hole for running through plastic box body 120 and PCBA board 130.
The box cover component 121 of plastic box body 120 and the inner wall of the through-hole on box component 122 are provided with screw thread, PCBA board
The inner wall of through-hole 1311 on 130 is also equipped with screw thread.When PCBA board 130 is placed in plastic box body 120, and PCBA board 130
On the through-hole opposite on the box cover component 121 of plastic box body 120 and box component 122 of through-hole 1311 be aligned after, PCBA board
The screw thread of through-hole 121 forms a whole spiral shell on relative position in screw thread and plastic box body 120 on the inner wall of through-hole 1311 on 130
Line, at this time by being fixed on PCBA board 130 in plastic box body 120 with the matched nut of screw thread.
It further include multiple impenetrating mouths in plastic box body 120 with continued reference to Fig. 2 and Fig. 3 on the basis of the various embodiments described above
123, the external pin of PCBA board 130 is arranged in impenetrating mouth 123.
Specifically, it there are many circuits or chip in PCBA board 130, needs to connect with external system to form human-computer interaction dress
It sets, therefore in PCBA board 130, there are multiple pins, connect for realizing with external system.In order to facilitate realization PCBA board
Pin on 130 is connect without being stopped by plastic box body 120 with external system, and multiple impenetrating mouths are arranged in plastic box body 120
123, the position of impenetrating mouth 123 corresponds to the position of 130 pin of PCBA board in plastic box body 120, and the size of impenetrating mouth 123
The pin in PCBA board 130 corresponding thereto can be accommodated to pass through, can be made at this time in the case where not opening plastic box body 120
Pin in PCBA board 130 is worn to penetrate impenetrating mouth 123 and external system and realize and be connected, therefore both can be with when installing PCBA board 130
From open plastic box body 120 installation steps, facilitate the installation of PCBA board 130, but can be avoided PCBA board 120 it is exposed
In air, either corroded by external collision.
The technical solution of the present embodiment makes the pin in PCBA board wear to penetrate and pass through by the way that impenetrating mouth is arranged in plastic box body
It wears mouth to connect to form human-computer interaction device with external system, the pin in PCBA board is realized in the case where plastic box body is in box body state
With the connection of external system, the installation of PCBA board was not only facilitated, but also plastic box body can have been made to protect PCBA board always.
The present embodiment continues to refer to figure 1 on the basis of the various embodiments described above, and the quantity of plastic box body 120 is at least one
It is a.
As shown in Figure 1, the plastic box body 120 being mounted in control handwheel box component 140 can have multiple, quantity depends on
In the quantity of required PCBA board 130.When PCBA board 130 has multiple, plastic box body 120 also has multiple.Preferably, plastic cement
The number of box body 120 is equal with the number of PCBA board 130, and a PCBA board 130 is placed in each plastic box body 120, is being pacified
It can be convenient installation when filling human-computer interaction device.
On the basis of above-mentioned each embodiment, control handwheel box component 140 includes multiple card slots, and plastic box body 120 is solid
Due to card slot.
The bottom surface of control handwheel box component 140 includes multiple card slots, for being fixedly mounted on the plastic box body of bottom surface
120.The quantity of plastic box body 120 at least one, therefore the quantity of card slot be it is multiple.In order to fix each plastic box body 120, often
The quantity at least two of the corresponding card slot of a plastic box body 120, and the position distribution of two card slots is in the week of plastic box body 120
The symmetric position on side.In order to keep plastic box body 120 more stable, the corresponding multiple card slots of each plastic box body 120 can be made, made
Every one side of plastic box body 120 is fixed with card slot.Therefore, the quantity of card slot is greater than the quantity of plastic box body 120.
There are many modes of the fixed plastic box body 120 of card slot, for example, card slot can be made to have bending shape, makes plastic box
The edge of body 120 is caught in card slot to fixed plastic box body 120.The bending shape part of card slot is perpendicular to control handwheel box body group
The thickness in the direction of 140 bottom surface of part is equal to the thickness of plastic box body 120, and card slot is made to avoid moving when fixing plastic box body 120
It is dynamic.Or screw thread is set on card slot, it is also provided with the screw thread of same size on the relative position of plastic box body 120, and with
Screw thread on card slot forms one, and by screwing in the plastic box body 120 that is screwed with the matched nut of screw thread, the length of nut is big
In or equal to the sum of the thickness of screw thread on screw thread and plastic box body 120 on card slot.
On the basis of above-mentioned each embodiment, control handwheel box component 140 further includes ground structure, for PCBA board
130 provide earth-return circuit.
Specifically, the grounding pin in PCBA board 130 is electrically connected with ground structure can be realized PCBA board 130 and is grounded back
