Description

Technical Field

[0001] This utility model relates to the field of remote control technology, and in particular to a remote control PCBA assembly structure. Background Technology

[0002] In remote control design, the Type-C interface has become the mainstream choice due to its universality and convenience. However, the frequent plugging and unplugging of the Type-C interface places high demands on the stability and durability of the connection. To ensure the stability and lifespan of the Type-C interface, current designs typically place two screws around the Type-C interface for enhanced fixation.

[0003] While this design effectively improves the durability of the Type-C interface and ensures it meets lifespan testing standards, it introduces new problems in practical operation. Particularly in the PCBA (Printed Circuit Board Assembly) section of the remote control, uneven stress distribution during screw fixing can easily cause the PCBA head to warp. This warping not only increases the difficulty of tightening the screws but may even prevent them from being fully tightened, thus affecting the overall structural stability and safety of the remote control. Furthermore, PCBA warping can also affect the snap-fitting of the remote control's bottom shell, reducing assembly efficiency and increasing production costs.

[0004] Therefore, how to solve the warping problem caused by PCBA mounting while ensuring the stability and lifespan of the Type-C interface, and improve the overall structural stability and assembly efficiency of the remote control, has become an urgent problem to be solved in the field of remote control design. Utility Model Content

[0005] The purpose of this utility model is to solve the shortcomings of the existing technology, such as uneven stress distribution caused by screw fixing, which easily leads to the lifting of the PCBA head, and to propose a remote control PCBA assembly structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a remote control PCBA assembly structure, including an interlocking front shell and a bottom shell:

[0008] A silicone pad, a dome switch, and a PCBA are sequentially placed between the front shell and the bottom shell. The front shell has holes that fit several button parts of the silicone pad.

[0009] The front shell and the bottom shell are connected by a snap-fit ​​structure, and the front shell is provided with positioning and locking components at both ends. The PCBA is fixed to the front shell by the positioning and locking components.

[0010] Furthermore, the fastening structure includes a first male buckle formed at both ends of the inner side of the face shell, and a first fastening groove at both ends of the bottom shell, wherein the first male buckle and the first fastening groove are fastened together.

[0011] Furthermore, it also includes a plurality of second male buckles formed on both sides of the bottom shell, and second buckle grooves are provided on both sides of the top shell, and the second male buckles and the second buckle grooves are engaged.

[0012] Furthermore, the outer edge of the face shell is formed with an annular protrusion, and the bottom of the bottom shell has an annular constriction, the annular constriction and the annular protrusion fitting together.

[0013] Furthermore, the positioning and locking assembly includes a third male buckle formed on one end of the inner side of the face shell, the third male buckle fastening to the upper side of the PCBA, two positioning holes being opened on the end face of the PCBA, and two connecting posts being fixedly installed on the inner side of the face shell, with bolts threaded through the positioning holes on the inner side of the connecting posts.

[0014] Furthermore, it also includes photovoltaic modules installed on the housing, with a window provided on the end face of the housing, and the photovoltaic modules installed in the window.

[0015] Furthermore, the photovoltaic module includes a bracket installed in the window, and a solar panel is connected to the inside of the bracket via adhesive backing.

[0016] The front end of the solar panel is connected to a lens via a lens adhesive, and the bracket is fixed to the PCBA by fasteners.

[0017] Furthermore, the inner side of the bottom shell is formed with protrusions, which abut against the rear side of the PCBA.

[0018] The present invention proposes a remote control PCBA assembly structure with the following advantages: In the traditional assembly process, two screws are required to secure the charging port at the rear of the PCBA to ensure that the charging port passes the plug-in / plug-out life test. However, when the screws are tightened, the head of the PCBA may lift up, which may result in the screws not being able to be tightened properly and may also affect the efficiency of the bottom shell fastening. Therefore, the present invention proposes a positioning and locking scheme, which involves adding a third male buckle below the first male buckle on the front shell to pre-fix the PCBA. Since the head of the PCBA can be well limited and fixed at this time, the above-mentioned risk points can be solved. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figure 1-5 As one embodiment of this utility model, a remote control PCBA assembly structure is disclosed. Specifically, the remote control structure includes a front shell 1 and a bottom shell 2 that interlock.

[0027] A silicone pad 3, a dome switch 4, and a PCBA 5 are placed sequentially between the front shell 1 and the bottom shell 2. The front shell 1 has holes for adapting to several button parts of the silicone pad 3. The specific control method and principle of the remote control are the conventional first choice for those skilled in the art, and will not be elaborated here.

[0028] The front shell 1 and the bottom shell 2 are connected by a fastening structure 6. Positioning and locking components 7 are provided at both ends of the front shell 1. The PCBA 5 is fixed to the front shell 1 by the positioning and locking components 7.

[0029] In some embodiments, the fastening structure 6 of this utility model includes a first male buckle 61 formed at both ends of the inner side of the front shell 1 and a first fastening groove 62 at both ends of the bottom shell 2. The first male buckle 61 and the first fastening groove 62 fasten together. In a preferred embodiment, two first male buckles 61 are formed on each inner end face of the front shell 1 to ensure the fastening stability with the bottom shell 2 and to ensure that the shell will not fall apart when the whole machine is dropped.

[0030] Furthermore, in order to improve the fastening stability of the bottom shell 2 and the top shell 1, this embodiment also includes a plurality of second male buckles 63 formed on both sides of the bottom shell 2, and second buckle grooves 64 are provided on both sides of the top shell 1, and the second male buckles 63 and the second buckle grooves 64 are fastened together.

[0031] It should be noted that the first male buckle 61 and the second male buckle 63 described in this embodiment have the same structure, both of which are set as rectangular structures. Of course, in order to ensure stable insertion during the buckling process, a guide bevel can also be opened on the end face of the first male buckle 61 and the second male buckle 63, thereby improving the convenience of buckling and docking.

[0032] Preferably, in this embodiment, the outer edge of the face shell 1 is formed with an annular protrusion 11, and the bottom of the bottom shell 2 has an annular contraction 21. The annular contraction 21 and the annular protrusion 11 fit together. Through the design of the annular protrusion 11 and the annular contraction 21, not only can they play a positioning role in the connection, but they can also improve the stability after the connection.

[0033] In some embodiments, the positioning and locking assembly 7 of this utility model includes a third male buckle 71 formed on one end of the inner side of the face shell 1. The third male buckle 71 is fastened to the upper side of the PCBA5. Two positioning holes 51 are opened on the end face of the PCBA5. Two connecting posts 12 are fixedly installed on the inner side of the face shell 1. The inner side of the connecting posts 12 is threaded with bolts passing through the positioning holes 51.

[0034] Specifically, in the traditional assembly process, two screws are needed to secure the charging port at the rear of PCBA5 to ensure that the charging port passes the plug-in / plug-out life test. When the screws are tightened, the head of PCBA5 will lift up, which may cause the screws to fail to tighten properly and also affect the bottom shell fastening efficiency. Therefore, this solution proposes a positioning and locking scheme, which is to pre-fix PCBA5 by adding a third male buckle 71 below the first male buckle 61 of the front shell 1. Since the head of PCBA5 can be well limited and fixed at this time, the above-mentioned risk points can be solved.

[0035] In addition, the present invention also includes a photovoltaic module 8 installed on the shell 1, and a window 13 is provided on the end face of the shell 1, and the photovoltaic module 8 is installed in the window 13.

[0036] Specifically, in this embodiment, the photovoltaic module 8 includes a bracket 81 installed in the window 13, and a solar panel 83 is connected to the inside of the bracket 81 by a bracket adhesive 82.

[0037] The front end of the solar panel 83 is connected to a lens 85 via a lens adhesive 84. The bracket 81 is fixed to the PCBA5 by a fastener 86. Specifically, in this embodiment, the fastener 86 is preferably a bolt. The solar panel 83 can be electrically connected to the supercapacitor on the PCBA5 to improve its battery life.

[0038] Preferably, in order to achieve the back end of PCBA5 abutting and fixing, the inner side of the bottom shell 2 in this embodiment is formed with a protrusion 22, which abuts against the rear side of PCBA5.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
