Description

Technical Field

[0001] This utility model belongs to the technical field of encoder mounting structure, and particularly relates to an encoder mounting structure and a speaker product. Background Technology

[0002] Encoders are frequently used in speaker products for volume control. The typical installation method involves mounting the encoder onto a printed circuit board (PCB) to implement its circuit control function, and then fixing the PCB inside the speaker enclosure, leaving the encoder's rotating shaft exposed for user use. However, because the encoder is only soldered to the PCB via its pins, this method of mounting is not robust enough. Daily twisting and impacts to the encoder shaft can easily cause the solder joints on the PCB to loosen, leading to poor contact between the encoder pins and the PCB circuitry, ultimately affecting the stability of the speaker's functionality. Utility Model Content

[0003] The purpose of this invention is to provide an encoder mounting structure and a speaker product that can ensure the stability of the circuit connection between the encoder and the printed circuit board.

[0004] In a first aspect, this application provides an encoder mounting structure, including: a mounting frame, a mounting panel, and an encoder;

[0005] The mounting frame has a first through hole;

[0006] The mounting panel extends in a first direction with a tubular structure adapted to the first through hole. The distal end of the tubular structure forms an inwardly circular ring structure. When the mounting panel is fixedly connected to the mounting frame, the distal end of the tubular structure fits into the first through hole.

[0007] The pins of the encoder are fixedly mounted on one side of the printed circuit board. The encoder has a first shaft at one end of the rotating shaft. The first shaft has an external thread and a second through hole. The rotating shaft of the encoder extends out from the second through hole.

[0008] The inner diameter of the ring structure is larger than the outer diameter of the first shaft of the encoder, and the inner diameter of the ring structure is smaller than the body size of the encoder. When the first shaft of the encoder extends into the tubular structure from the far end of the tubular structure, the body of the encoder is blocked by the ring structure. The encoder can be locked in the ring structure by the external thread of the first shaft and the matching nut.

[0009] Optionally, the mounting panel extends toward the first direction with mounting posts, and two or more deformable ribs are evenly distributed on the outer side of the mounting posts along the first direction.

[0010] The mounting surface of the mounting frame connected to the mounting panel is provided with mounting holes adapted to the diameter of the mounting column, so that the mounting column can be squeezed and deformed by the deformation ribs to achieve an interference fit connection with the mounting holes.

[0011] Optionally, the distal end of the mounting post is chamfered, and the height of the deformable rib at the distal end of the mounting post gradually decreases to match the chamfer.

[0012] Optionally, the length of the tubular structure is equal to or less than the length of the encoder's rotating shaft.

[0013] Optionally, it includes: two or more encoders mounted on the same printed circuit board;

[0014] The mounting frame has two or more of the first through holes;

[0015] The mounting panel extends in the first direction and has two or more tubular structures that are adapted to the first through hole.

[0016] Optionally, the printed circuit board is fixedly mounted to the mounting frame from inside the mounting frame using fasteners.

[0017] Optionally, the rotation center axis of the first through hole, the rotation center axis of the tubular structure, the rotation center axis of the annular plate structure, the rotation center axis of the first shaft, and the rotation center axis of the encoder are collinear.

[0018] Optionally, a knob cover is also included;

[0019] The knob cover is detachably connected to the rotating shaft of the encoder.

[0020] Optionally, the top of the knob cover is provided with a rotation direction indicator for adjusting the target function size;

[0021] The mounting panel surrounding the tubular structure is provided with an encoder target function identifier corresponding to the tubular structure.

[0022] Secondly, this application provides a speaker product, including the encoder mounting structure described in any one of the first aspects above, wherein the mounting frame in the encoder mounting structure is the speaker body.

[0023] As can be seen from the above technical solutions, this embodiment has the following advantages:

[0024] The encoder mounting structure in this embodiment includes: a mounting frame, a mounting panel, and an encoder; wherein the mounting frame has a first through hole; the mounting panel extends in a first direction with a tubular structure adapted to the first through hole, and the distal end of the tubular structure forms an inwardly formed annular plate structure, so that when the mounting panel is fixedly connected to the mounting frame, the distal end of the tubular structure fits into the first through hole; the encoder pins are fixedly mounted on one side of the printed circuit board, and the encoder has a first shaft at one end with a rotating shaft, the first shaft having an external thread and a second through hole, the encoder's rotating shaft extending out from the second through hole; the inner diameter of the annular plate structure is larger than the first through hole of the encoder. The outer diameter of the shaft and the inner diameter of the ring structure are smaller than the size of the encoder body. When the first shaft of the encoder extends into the tubular structure from the far end, the encoder body is blocked by the ring structure. The encoder can be locked to the ring structure by the external thread of the first shaft and the matching nut, thus realizing the fixed connection between the encoder and the tubular structure of the mounting panel. In this way, the first shaft of the encoder is also supported by force in the daily twisting and possible impacts of the encoder's rotating shaft, reducing the relative movement between the encoder pins and the printed circuit board, and ensuring the stability of the circuit connection between the encoder and the printed circuit board.

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0034] Please see Figure 1 , Figure 2 as well as Figure 3 The existing method of installing encoders in speaker products is as follows: First, the pin adapters of encoder 110 are soldered and fixed to the pads of the corresponding circuit on the printed circuit board (PCB) 120, so that encoder 110 is one of the components in the circuit. Then, the PCB 120 is installed inside the speaker body 140 of the speaker product by screws 131, so that the rotating shaft 111 of encoder 110 is exposed on the speaker body 140. The surface of the speaker body 140 exposing the rotating shaft 111 is also provided with a mounting panel 150. The mounting panel 150 is fixed to the speaker body 140 by screws 132. The mounting panel 150 has a through hole 151 that exposes the rotating shaft 111 of encoder 110. The mounting panel 150 is usually made of a more wear-resistant material than the speaker body 140, such as metal or alloy. However, since the encoder 110 is only soldered to the printed circuit board 120 through its pins, the connection strength of the encoder 110's fixing method is insufficient. In the daily twisting and possible bumps of the encoder 110's rotating shaft 111, the solder connection of the encoder 110 on the printed circuit board can easily become loose, resulting in poor contact between the encoder 110's pins and the circuit connection of the printed circuit board 120, which in turn affects the stability of the speaker product's function.

[0035] Please see Figure 4 The encoder 210 used in this invention has a different structure from the encoder 110 in the prior art. The encoder 210 of this invention has a first shaft 212 at one end of a rotating shaft 211. This first shaft 212 has an external thread and a second through hole. The rotating shaft 211 of the encoder 210 extends out from the second through hole. It should be noted that encoders with external threads are existing technology and can be purchased on the market, such as encoders produced by Dongguan Taotao Electronics Co., Ltd., with models such as EC11A11V01-0193GB120P1AT155F070. Further details about encoders with external threads will not be provided here.

[0036] Please see Figure 5 , Figure 6 , Figure 7 as well as Figure 8The encoder mounting structure of this utility model includes: a mounting frame 240, a mounting panel 250, and an encoder 220; wherein the mounting frame 240 has a first through hole 241; the mounting panel 250 faces a first direction (e.g., Figure 5 As shown, a tubular structure 251, typically perpendicular to the panel plane of the mounting panel 250, extends to fit the first through hole 241. A circular ring structure 252 is formed inwardly at the distal end of the tubular structure 251. When the mounting panel 250 is fixedly connected to the mounting frame 240, the distal end of the tubular structure 251 fits into the first through hole 241. The pins of the encoder 210 are fixedly mounted on one side of the printed circuit board 220 using solder, making the encoder 210 one of the components in the circuit of the printed circuit board 220. The inner diameter of the circular ring structure 252 is larger than the outer diameter of the first shaft 212 of the encoder 210, and the inner diameter of the circular ring structure 252 is smaller than the size of the body 213 of the encoder 210. When the first shaft 212 of the encoder 210 extends from the tubular structure... When the distal end of the structure 251 extends into the tubular structure 251, the body 213 of the encoder 210 is blocked by the annular plate structure 252. The encoder 210 can be locked in the annular plate structure 252 by the external thread of the first shaft 212 and the matching nut 214 with internal thread, thereby realizing the fixed connection between the encoder 210 and the tubular structure 251 of the mounting panel 250. The mounting panel 250 is fixedly connected to the mounting frame. In this way, the first shaft 212 of the encoder 210 is also used as a force support when the rotating shaft 211 of the encoder 210 is twisted in daily life and may be bumped, reducing the relative position movement between the pins of the encoder 210 and the printed circuit board 220, and ensuring the stability of the circuit connection between the encoder 210 and the printed circuit board 220.

[0037] For further details, please refer to Figure 6 The mounting panel 250 of the encoder mounting structure of this utility model extends in a first direction with a plurality of mounting posts 253. Each mounting post 253 has two or more deformation ribs 254 evenly distributed on its outer side along the first direction. The mounting surface 242 of the mounting frame 240, which connects to the mounting panel 250, is provided with mounting holes 243 that match the diameter of the mounting posts 253. This allows the mounting posts 253 to undergo compression deformation through the deformation ribs 254 and achieve an interference fit connection with the mounting holes 243. This enables a fixed connection between the mounting panel 250 and the mounting frame 240 without the need for fasteners, saving costs. In a further embodiment, the distal end of the mounting post 253 is chamfered, and the height of the deformation ribs 254 gradually decreases at the distal end of the mounting post 253 to facilitate the insertion of each mounting post into the corresponding mounting hole for an interference fit connection.

[0038] Furthermore, the length of the tubular structure 251 of the mounting panel 250 of the encoder mounting structure of this utility model is equal to or less than the length of the rotating shaft 211 of the encoder 210, so that the rotating shaft 211 of the encoder 210 can be flush with or exposed on the mounting surface 242 of the mounting panel 250, facilitating the installation of the knob cover (not shown in the figure); the knob cover is detachably connected to the rotating shaft 211 of the encoder 210, and the knob cover is used to enlarge the rotation diameter of the rotating shaft 211, making it easier for the user to grip and rotate to adjust the rotating shaft 211 of the encoder 210; furthermore, the top of the knob cover may be provided with a rotation direction indicator for adjusting the size of the target function (e.g., volume adjustment function) (e.g., clockwise rotation increases the volume, counterclockwise rotation decreases the volume); the mounting panel 250 around the tubular structure 251 (mainly referring to the upper surface 255) is provided with the encoder 210 target function indicator (e.g., volume adjustment) corresponding to the tubular structure 251, so that the user knows its corresponding function.

[0039] In another embodiment, the encoder mounting structure of this utility model can have two or more encoders 210 mounted on the same printed circuit board 220; the mounting frame 240 has two or more first through holes 241; the mounting panel 250 extends in a first direction with two or more tubular structures 251 that adapt to the first through holes 241, to accommodate the need for multiple encoders to be mounted on the mounting frame. Specifically, the printed circuit board 220 is generally fixed to the mounting frame 240 from inside the mounting frame 240 by fasteners (e.g., screws 230).

[0040] Specifically, in the encoder mounting structure of this utility model, the rotating center shafts of the first through hole 241 of the mounting frame 240, the rotating center shafts of the tubular structure 251, the rotating center shafts of the annular plate structure 252, the rotating center shafts of the first shaft 212, and the rotating center shafts of the encoder 210 are collinear.

[0041] In addition, this utility model also provides a speaker product, which includes the encoder mounting structure mentioned in any of the above embodiments, wherein the mounting frame in the encoder mounting structure is the speaker body.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
