Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

The massage instrument key structure shown in fig. 1 to 7 comprises an upper shell 2 and a PCBA board 1, wherein a key module is arranged between the upper shell 2 and the PCBA board 1, the key module comprises at least two keys 3, the keys 3 are connected by a key connector 6 to form an integral structure, and the keys 3 are fixedly arranged on the upper shell 2 by the key connector 6; when the key 3 is pressed down, the contact of the key 3 is contacted with the corresponding switch 5 on the PCBA board 1; when the key 3 is released, the contact of the key 3 is reset by the elastic force of the key connector 6.

The existing massage instrument keys are provided with various corresponding auxiliary parts such as springs and mounting clamping grooves, so that the number of the whole parts is large, and the assembly time and the assembly error are increased. In addition, too many keys not only affect the appearance and have poor operability, but also cause the situation that the reset structure of a single key is complex and is easy to fail, thereby bringing about the problem of cost increase. In the scheme, all the keys 3 are connected into an integral structure through the key connecting piece 6, so that the assembly time and the assembly error are greatly reduced during assembly. The key 3 can be fixedly arranged on the upper shell 2 through the key connecting piece 6, and a corresponding installation positioning part is also omitted. At the same time, the elastic force of the key connecting piece 6 also realizes the reset of the key 3. Generally, in order to simplify the structure of the key connector 6, it is preferable that the key connector 6 is an elastic arm 6 as shown in fig. 3. The elastic arm 6 may be made of plastic or rubber, or other materials meeting the requirements of strength and toughness. Preferably, an integral injection molding structure is arranged between the key 3 and the key connecting piece 6, so that the preparation process is simplified, the cost is further reduced, and the stability of the whole structure and the installation efficiency are improved.

In order to facilitate the fixing of the key connecting element 6, the following structure is preferred: the inner wall surface of the upper shell 2 is provided with at least one hot-melting column 7, the key connecting piece 6 is provided with at least one hot-melting column positioning hole 71, and the key connecting piece 6 is fixedly arranged on the hot-melting column 7 through the hot-melting column positioning hole 71. As shown in fig. 3 and 5, the key connecting piece 6 can be quickly and accurately mounted on the hot-melting column 7 through the hot-melting column positioning hole 71, and finally the key connecting piece 6 is finally fixed inside the upper shell 2 in a hot-melting mode, so that the stable mounting and fixing of the key connecting piece 6 are effectively ensured, and the key connecting piece 6 can provide sufficient elastic force.

In order to control a plurality of functions corresponding to a single key 3, the following scheme is preferred: the button 3 includes two at least contacts, and wherein, the central point of button 3 is provided with wane fulcrum 4, the end and the PCBA board 1 counterbalance setting of wane fulcrum 4. As shown in fig. 7, each contact is provided in one-to-one correspondence with the switches 5 on the PCBA board 1. When a certain part of the key 3 is pressed, the contact point corresponding to the pressed part is contacted with the switch 5 on the PCBA board 1, and at the moment, the rest contact points are far away from the corresponding switch 5 due to the rocker effect of the rocker fulcrum 4, so that the contact points are prevented from being touched by mistake. The ingenious design realizes the control of a single key to a plurality of functions, and further simplifies the key structure. Generally, in order to make the pressing of the key 3 more accurate and further prevent the erroneous contact, it is preferable that the contacts of the key 3 are uniformly distributed around the rocker fulcrum 4. Taking fig. 5 to 7 as an example, the key 3 is a long-strip-shaped key, wherein two ends of the key 3 are respectively provided with a first contact 311 and a second contact 321, and the rocker fulcrum 4 is disposed at the middle portion of the key 3. The first contact 311 and the second contact 321 are located at two ends of the rocker fulcrum 4, and when the first force-bearing area 31 is pressed, the first contact 311 contacts with a corresponding switch on the PCBA board 1, so that the function triggering is realized. When the second force-bearing area 32 is pressed, the second contact 321 makes contact with a corresponding switch on the PCBA board 1, thereby achieving its functional triggering. When the third force-bearing zone 33 is pressed, no function is triggered due to the presence of the rocker fulcrum 4. If the key 3 has only one contact point, the contact point is located in the middle of the key 3. Regarding the function setting of the keys 3, taking fig. 1 as an example, the three keys 3 may be a key for a mode adjusting function, a key for a power control function, and a key for a gear adjusting function, respectively.

In actual design, the lower shell 21 may be used to implement the rocker fulcrum 4, as shown in fig. 8, the rocker fulcrum 4 includes the lower shell 21, and the rocker fulcrum 4 is a bone position top 22 disposed on the lower shell 21. The lower shell 21 is provided with a bone position, and the top 22 of the bone position is used as a fulcrum, namely a rocker fulcrum 4, so that the key 3 is supported. Preferably, in order to facilitate the structural arrangement, the PCBA plate 1 is preferably provided with a through hole, and the bone position top end 22 is arranged to abut against the key 3 after penetrating through the through hole. And the PCBA board 1 may be provided on the lower case 21. In order to increase the contact surface of the contact of the key 3 with the switch 5 on the PCBA board 1, the contact of the key 3 preferably has a cross-shaped cross-sectional shape.

In order to facilitate the key 3 to have sufficient movement space when the rocker is pressed by the key 3, so as to prevent the key 3 from interfering with the upper casing 2 and failing to realize the pressing function, as shown in fig. 7, a key gap 34 is preferably provided between the peripheral edge of the key 3 and the upper casing 2. The key gap 34 ensures a sufficient moving space for the key 3 to be pressed and reset, so that the operation of the key 3 is smoother. As shown in fig. 4, to facilitate mounting and dismounting of the PCBA board 1, the PCBA board 1 is preferably mounted on the upper case 2 by means of connecting screw posts 12.
