The technical solution of the present application will be explained with reference to specific embodiments.
Fig. 1 and 2 are perspective views of a key mounting assembly structure in an embodiment provided in the present application, and as shown in fig. 1-2, the key mounting assembly structure includes at least one key assembly mounted on a circuit board 1, where the key assembly includes a key body 3, a connecting member 6, and an elastic hook 2;
the elastic hook 2 is fixedly connected with the key body 3 through a connecting piece 6;
at least one limiting hole 11 is formed in the circuit board 1, and the elastic hook 2 is embedded in the corresponding limiting hole 11;
and a gap is arranged between the elastic hook 2 and the circuit board 1, and the gap is used for enabling the key body 3 to normally trigger the switch button 13 on the circuit board 1.
In this embodiment, the circuit board 1 may be a PCBA board, a PCB board, or the like for implementing a key function in cooperation with a key; the structure of the connecting element 6 is not limited, and it may be a part of the elastic hook 2, or may be another element between the elastic hook 2 and the key body 3 that can realize the connection between the key body 3 and the elastic hook 2.
In addition, the arrangement of the gap between the elastic hook 2 and the circuit board 1 can ensure that the elastic hook 2 can be normally inserted into the limiting hole 11 under the pressing action and the elastic hook 2 cannot be separated from the limiting hole 11 when being in a natural opening state; in addition, the key body 3 can be moved downwards to trigger the switch button 13 on the circuit board 1 to realize the key function, and after the pressure acting on the key body 3 is removed, the key body can be reset under the action of the elastic component 31 of the key body and is not contacted with the switch button 13; therefore, the clearance between the elastic hook 2 and the circuit board 1 can also ensure the required moving space when the elastic hook 2 moves synchronously along with the key body 3 when the key body 3 is normally pressed and reset.
In one implementation, as shown in fig. 1-2, the key assembly further includes a key positioning post 22, and the circuit board 1 is provided with a corresponding positioning hole 12, because the key has a silk-screen functional symbol, if the key is installed reversely, the silk-screen functional symbol may not be consistent with the actual function, thereby misleading the user and causing trouble to the user; for example, the volume up key is represented by "Δ" of silk screen printing, and the volume down key is represented by "Δ" of silk screen printing, if the keys are turned by 180 ° in an incorrect manner during installation, the function symbols of the volume keys are inconsistent with the actual functions, so that the key positioning columns 22 and the corresponding positioning holes 12 are arranged, and when the keys are installed, the key positioning columns 22 are inserted into the corresponding positioning holes 12, so that the problem of key installation reversal does not occur.
In one implementation mode, the elastic hooks 2 are a group symmetrically arranged along the central line of a circle where the key body 3 is located; this a set of elastic hook 2 that the symmetry set up can guarantee that the assembly of button body 3 is reliable and stable more, and makes button body 3 realize pressing down with the atress balanced when reset function.
In one implementation mode, the key body 3, the connecting piece 6 and the elastic hook 2 can be integrally formed, or any two of the key body, the connecting piece and the elastic hook can be integrally formed, so that the parts can be manufactured in one step, and the key is convenient and quick.
In one implementation manner, as shown in fig. 4, the elastic hook 2 includes a straight line section 21 and a hook section 23, the straight line section 21 is fixedly connected with the connecting piece 6, and the hook section 23 passes through the limiting hole 11; the hook section 23 is arranged so that after the elastic hook 2 is inserted into the limiting hole 11, the hook section 23 does not come out of the limiting hole 11 when being in a natural opening state.
As shown in fig. 5-8, in this embodiment, the straight-line section 21 of the elastic hook 2 and the portion of the key body 3 on the same side as the circuit board 1 are provided with an elastic hook limiting portion 24, and the elastic hook limiting portion 24 is used for making the elastic hook limiting portion 24 contact with the circuit board 1 when the key body 3 is in a reset state after the elastic hook 2 is inserted into the limiting hole 11; for example, the length of the elastic hook limiting portion 24 is set to be greater than the length of the limiting hole 11, or the width of the elastic hook limiting portion 24 is set to be greater than the width of the limiting hole 11, so that the contact portion of the elastic hook limiting portion 24 and the circuit board cannot pass through the limiting hole 11, and after the hook section 23 of the elastic hook 2 is completely inserted into the limiting hole 11, when the key body 3 is in the reset state, the elastic hook limiting portion 24 contacts the circuit board 1, and the limiting and fixing effects are achieved.
The key positioning post 22 may be disposed on one side of the elastic hook stopper 24, and the key positioning post 22 is inserted into the positioning hole 12 when the elastic hook 2 is assembled.
As shown in fig. 7-9, in the present embodiment, the gap includes a first gap 51 and a second gap 52, the first gap 51 is a distance between the tip of the hook section 23 of the elastic hook 2 and the surface of the circuit board 1, and the second gap 52 is a distance between the straight section 21 of the elastic hook 2 and the side wall of the limiting hole 11; the arrangement of the first gap 51 can ensure a movement space required by the synchronous movement of the elastic hook 2 along with the key body 3 when the key body 3 is normally pressed and reset; the second gap 52 is provided to ensure that the elastic hook 2 can be normally inserted into the position-limiting hole 11 under the pressing action, and the hook section 23 of the elastic hook 2 will not be separated from the position-limiting hole 11 when in a natural opening state.
In this embodiment, the first gap range may be set to 0-0.15mm, and the second gap range may be set to 0-0.1 mm; above-mentioned clearance scope set up the effect better, neither can cause elasticity hook 2 not to install well because the clearance is too little, has the interference, also can not cause the not hard up problem of assembly because the clearance is too big, in addition near loudspeaker key assembly, if the clearance too big still can cause the tremolo.
In addition to the above key mounting assembly structure, the present application also provides an electronic device including the key mounting assembly structure disclosed in the above embodiment, which may be, for example, a display device such as a television with keys, an educational large screen, or the like;
as shown in fig. 10-11, after the key assembly is completely assembled, the key assembly is fixed to the electronic device together with the key box 4, the hardware bracket, and the adapting rivet, so as to complete the assembly of the keys.
The embodiments given above are preferable examples for implementing the present application, and the present application is not limited to the above-described embodiments. Any non-essential addition or replacement made by a person skilled in the art according to the technical features of the technical solution of the present application falls within the scope of the present application.
