Referring to fig. 1 to 4, an embodiment of the present invention discloses a remote controller 100, which can be applied to electronic products (such as massage apparatuses, beauty instruments, food mixers, televisions, air conditioners, etc.), and used as a wireless transmitter to control functions of the electronic products. Specifically, the remote control 100 includes a first housing 10 and a second housing 20, and the second housing 20 and the first housing 10 are connected to form a receiving cavity 21. The receiving cavity 21 may have a PCB30 disposed therein. One side of the second casing 20 facing the PCB30 is provided with one or more fastening holes or studs 22 arranged at intervals, and the PCB30 is provided with one or more studs or fastening holes 31 arranged at intervals.

Adopt second casing 20 and PCB30 to pass through projection and card hole complex mode, the mounting means is swift simple and convenient, has replaced the tradition mode of adopting the fix with screw, is favorable to improving this PCB 30's installation effectiveness.

In addition, the convex columns or the clamping holes can be arranged in a plurality of modes, so that multipoint positioning of the PCB30 can be realized, and the assembly stability of the PCB30 is effectively improved.

The involution connection between the second casing 20 and the first casing 10 means: the second housing 20 and the first housing 10 are disposed in an opposite direction to each other, and the first housing 10 and the second housing 20 are coupled to form a cavity therebetween. In addition, the way of the involutory connection of the second casing 20 and the first casing 10 may include, but is not limited to, screwing, snap connection, bolting, etc.

Alternatively, the remote controller may be an elongated remote controller, and thus, the second housing 20 and the first housing 10 may be elongated housings, such as an oval housing, a square housing, and the like.

In this embodiment, when the PCB30 is mounted in the receiving cavity 21 formed by the second housing 20 and the first housing 10, the opposite first and second faces 30a and 30b of the PCB30 may be disposed toward the second housing 20 and the first housing 10, respectively. That is, the first face 30a of the PCB30 is provided with the card hole 31 and disposed toward the second housing 20, and the second face 30b of the PCB30 is disposed toward the first housing 10, so that the PCB30 is just sandwiched between the first housing 10 and the second housing 20, and the mounting stability of the PCB30 can be further improved by using the second housing 20 and the first housing 10.

In an alternative embodiment, when the boss 22 is disposed on the second housing 20, the PCB is disposed with the locking hole 31. In this embodiment, since the card hole is formed in the second case 20, when the card hole is formed in the second case 20, a convex pillar portion may be formed on a surface of the second case 20 facing the PCB30, and then the card hole may be formed in the pillar portion. This is done to avoid the situation where the hole is made directly in the second housing 20, which is advantageous for ensuring the structural integrity of the second housing 20.

In another alternative embodiment, when the second housing 20 is provided with a locking hole, the PCB may be provided with a protruding pillar.

The present embodiment will be described by taking a case where the boss 22 is provided on the second housing 20 and the card hole 31 is provided on the PCB30 as an example.

In view of the mounting security between the PCB30 and the second housing 20, the protruding pillar 22 may be a stepped pillar, optionally a stepped cylinder, which may include a first pillar 22a and a second pillar 22b, the first pillar 22a may be disposed on a side of the second housing 20 facing the PCB30, the second pillar 22b may be disposed on the first pillar 22a, and the outer diameter of the second pillar 22b is smaller than the outer diameter of the first pillar 22a, and the inner diameter of the locking hole matches the outer diameter of the second pillar 22 b. That is, the inner diameter of the card hole is smaller than, slightly larger than or equal to the outer diameter of the second cylinder 22b, so that when the PCB30 and the second housing 20 are assembled, the second cylinder 22b can be inserted into the card hole 31 of the PCB30, and thus the second cylinder 22b and the card hole 31 can be in interference fit or transition fit, and the assembly manner is simple.

It is understood that when the card hole is formed on the second housing 20, the stud is formed on the PCB30, and then the first cylinder may be formed on the PCB 30.

It can be known that when the protruding columns 22 are stepped columns and there are a plurality of protruding columns, all the protruding columns 22 may be stepped columns, or a part of the protruding columns 22 may be stepped columns, and another part of the protruding columns 22 may be straight columns. Taking two convex columns 22 as an example, one of the convex columns 22 may be a stepped column, and the other convex column 22 may be a straight column. Of course, it is also possible to provide that both studs 22 are stepped studs.

Further, since the outer diameter of the second cylinder 22b is smaller than that of the first cylinder 22a, a step surface 220 is formed at the junction of the second cylinder 22b and the first cylinder 22a, and the step surface 220 abuts against the plane of the card hole 31. That is, when the second cylinder 22b is inserted into the card hole 31 of the PCB30, the step surface 220 can just abut on the first surface 30a of the PCB30, thereby fixing the PCB30 and defining the mounting position of the PCB30 on the second housing 20.

Therefore, in order to facilitate the matching of the second cylinder 22b and the locking hole 31, an end surface of the second cylinder 22b far from the first cylinder 22a may be provided as an inclined surface, specifically, inclined in a direction toward the locking hole 31, that is, an outer diameter of the second cylinder 22b is reduced from a connection point with the first cylinder 22a to a direction far from the first cylinder 22a, and is minimized at an end surface of the second cylinder 22b far from the first cylinder 22a, so that the matching of the second cylinder 22b and the locking hole 31 can be guided, and the matching of the second cylinder 22b and the locking hole 31 is facilitated.

In this embodiment, in order to further improve the assembly stability of the PCB30, a top pillar 11 extending toward the PCB30 may be disposed on a surface of the first housing 10 facing the PCB30, and the top pillar 11 may abut against a second surface 30b of the PCB30, so that, for the PCB30, the first surface 30a abuts against the step surface 220 on the stud 22, and the second surface 30b abuts against the top pillar 11, so that the two surfaces of the PCB30 are respectively abutted and fixed by the second housing 20 and the first housing 10, thereby effectively improving the connection stability of the PCB 30.

Alternatively, one or more of the top pillars 11 may be provided, and when provided in plural, the plurality of top pillars 11 may be provided at intervals. The use of a plurality of top pillars 11 can further improve the abutting effect of the first housing 10 on the PCB30, and ensure the stability of the installation of the PCB30 in the accommodating chamber 21.

Referring to fig. 2 to 6, in the present embodiment, as can be seen from the foregoing, the second casing 20 may be an elongated casing, and the protruding pillar 22 may be disposed at one end of the second casing 20. In order to realize the remote control key function of the remote controller, the other end of the second casing 20 may be provided with a key hole 23, and the key hole 23 may be communicated with the accommodating cavity 21, so that the key installed at the key hole 23 may be electrically connected to the PCB30 located in the accommodating cavity 21. Alternatively, the key hole 23 may be a circular hole, a circular-like hole (e.g., an elliptical hole), a square hole, or the like, which is not limited in this embodiment.

For example, as shown in fig. 5, fig. 5 is a schematic structural diagram of the second housing 20. In fig. 2, the second casing 20 is located at one end of the second casing 20 to the left in the paper plane direction, and the second casing 20 is located at the other end thereof to the right in the paper plane direction. Thus, as can be seen from fig. 5, the boss 22 is disposed at the left end of the second casing, and the key hole 23 is disposed at the right end of the second casing 20.

Further, in order to improve the assembly stability of the PCB30, two first limiting posts 24 arranged at intervals are disposed on a surface of the second housing 20 facing the PCB30, specifically, on the periphery of the key hole 23, and the interval between the two first limiting posts 24 is just used for clamping an end of the PCB30 (e.g., the right end in the paper direction in fig. 2), so that, for the PCB30, the end of one end of the PCB is just limited by the two first limiting posts 24, and the other end of the PCB is just connected with the clamping hole through the protruding post, so that the displacement of the PCB30 along its own length direction can be limited, thereby improving the connection stability of the PCB 30.

The peripheral edge of the key hole 23 is an area formed around the key hole 23 along the opening boundary of the key hole 23.

Alternatively, the two first limiting columns 24 may be arranged just on one side of the peripheral edge of the key hole 23. The spacing between the two first limiting columns 24 can be matched according to the size of the end of the PCB.

In addition, because the spacing post 25 of second sets up at the other end of second casing 20, and the projection then sets up the one end at second casing 20 to the cooperation that makes PCB 30's both ends is inequality, can play effectual foolproof effect when assembling to PCB30, further improves PCB 30's assembly efficiency.

Optionally, the first limiting column 24 and the second limiting column 25 may be both cylinders or square columns, and the structures and the sizes of the first limiting column 24 and the second limiting column 25 may be the same or different, which is not specifically limited in this embodiment.

In this embodiment, a key 23a may be disposed at the key hole 23, and the key 23a may be a silicone key to improve the pressing comfort of the user. Optionally, in order to effectively fix the key 23a, a bead 23b may be formed by extending upward along a circumference of the key hole 23, the bead 23b and the second limiting pillar 25 are arranged at an interval, specifically, the bead 23b may be arranged on a side of the key hole 23 away from the first limiting pillar 24, a flange 230 may extend along the circumference of the key 23a, an outer diameter of the flange 230 is greater than an inner diameter of the key hole 23, and the flange 230 is connected to the bead 23 b. That is, the design of the pressing strip 23b and the flange 230 can fix the button 23a in the button hole 23, so as to prevent the button 23a from falling out of the button hole 23.

The shape of the pressing strip 23b can be set according to the shape of the key hole 23, for example, the pressing strip 23b can be an approximately arc-shaped pressing strip. The pressing strips 23b can be one or more, and when one pressing strip 23b is provided, the pressing strip 23b can be arranged on one side of the key hole 23 far away from the first limiting column 24 and is opposite to the first limiting column 24. When the pressing strips 23b are multiple, one of the pressing strips 23b can be disposed on one side of the key hole 23 away from the first limiting column 24 and opposite to the first limiting column, and the other pressing strip 23b can be disposed on one side or both sides of the one pressing strip 23 b. For example, as shown in fig. 5, it shows a view when the pressing strips 23b are three strips, wherein one of the pressing strips 23b is disposed just at a side of the key hole 23 away from the first position-limiting pillar 24 and is opposite to the first position-limiting pillar 24, and the other two pressing strips 23b are disposed at two sides of the one of the pressing strips 23 b.

That is, the key 23a is located between the PCB30 and the key hole 23, so that the PCB30 can also function as an auxiliary limit key 23a, thereby improving the installation stability of the key 23a in the key hole 23.

Optionally, in order to improve the pressing feel of the key 23a and prevent the key 23a from falling out of the key hole 23, an elastic pressing rib 231 may be convexly disposed on a surface of the key 23a facing the PCB30, and the elastic pressing rib 231 may be in a ring shape, specifically, an elliptical ring shape that is circumferentially disposed around the periphery of the key hole 23 and is adapted to the shape of the key hole. When the key 23a is mounted in the key hole 23, the elastic pressing rib 231 can press against the first surface 30a of the PCB 30. Thus, the elastic rib 231 can provide a space between the surface of the key 23a and the PCB30, so as to allow the key 23a to have a certain stroke when the key 23a is pressed, which is beneficial for pressing the key 23 a. In addition, the elastic pressing rib 231 is pressed on the PCB30, so that the installation stability of the key 23a can be further improved, and the key 23a is prevented from falling out of the key hole 23.

Alternatively, in order to ensure the manipulation sensitivity of the key 23a, the top pillar 11 disposed on the first casing 10 may be disposed corresponding to the position of the key dome 33, so that not only the installation space may be saved, but also, when the key 23a is pressed, due to the disposition of the top pillar 11, the displacement of the PCB30 toward the first casing 10 may be limited, so that the manipulation sensitivity of the key 23a may be ensured.

The installation process of the remote controller 100 of the present embodiment is briefly described below:

before the second housing 20 and the first housing 10 are mounted, the fastening hole 31 of the PCB30 is aligned with the stud 22 of the second housing 20, so that the second post 22b extends into the fastening hole 31 of the PCB30, and the first surface 30a of the PCB30 abuts against the step surface 220 of the stud.
