Technical Field

[0001] This utility model relates to a novel dial encoder, belonging to the field of electronic component technology. Background Technology

[0002] For small peripheral electronic products like headphones, the encoder used should not be too large. A search revealed a patent with publication number "CN2891246Y" that discloses a dial encoder with a switch to address this issue.

[0003] Similarly, the applicant has designed a new type of dial encoder and has filed the following application. Utility Model Content

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a novel dial encoder, comprising a base, wherein a brush platform with brushes is elastically slidably disposed in the inner cavity of the base, and a code disk with a dial fastened to its top is rotatably disposed on the brush platform, wherein an elastic positioning piece provided on the brush platform abuts against the toothed ring formed by the code disk; by rotating the dial, the brushes can alternately contact the code pieces embedded in the code disk, and by pushing the dial, the brushes can connect with the conductive terminals of the base.

[0006] Preferably, the code disk has three protruding pillars at its center, which are enclosed by ribs to form a positioning part.

[0011] Preferably, the brush table has a stop protrusion for abutting against the bent portion of the positioning piece.

[0012] Preferably, the base is provided with a torsion spring for driving the brush table to reset, and the movable end of the torsion spring abuts against the opening slot of the brush table.

[0013] Preferably, the base includes an upper cover and a base that are joined together, and a conductive terminal for contacting the brush extends from the outside of the base into the inside of the base.

Detailed Implementation

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1-5As shown: A novel dial encoder includes a base 1 formed by the assembly of an upper cover 101 and a base 102 to form an inner cavity. A brush platform 2 with a brush 3 is slidably disposed in the inner cavity of the base 1. A code disk 5 with a dial 4 is rotatably disposed on the top of the brush platform 2. Pushing the dial 4 can make the brush 3 of the brush platform 2 contact with the conductive terminal 112 provided on the base 1 to achieve connection. Rotating the dial 4 can make the brush 3 alternately contact with the code chip 7 embedded therein.

[0027] Furthermore, the aforementioned code disk 5 and dial 4 are fixed to each other by a snap-fit ​​mechanism; such as Figure 3 As shown, the circular boss 501 on the top of the code disk 5 has three protruding pillars 512 forming upwards. The protruding pillars 512 are connected to each other by ribs 522 to form a triangular positioning part. The dial 4 has a countersunk hole 401 with a triangular hole machined in its center. After the positioning part 502 of the code disk 5 passes through the triangular hole and enters the countersunk hole 401, it can be fastened to the countersunk hole 401 by the latches 532 of the ribs 522. Through this fastening design, the code disk 5 and the dial 4 can avoid the two from separating to the greatest extent and reduce the potential quality problems of the product.

[0028] Furthermore, the brush station 2 itself has a sandwich layer, and the brush 3 is clamped and fixed in the sandwich layer, with a portion protruding outward from the through hole of the brush station 2. The protruding portion of the brush 3 is used to contact and cooperate with the conductive terminal 112 and the code chip 7 provided on the base 1.

[0029] Specifically, such as Figures 4-5 As shown, a toothed ring 503 is formed on the inner side of the encoder 5. The positioning piece 6, which is locked in the slot of the brush table 2 at both ends, forms a bent portion 601 in its middle that matches the tooth position of the toothed ring 503. The positioning piece 6 has a certain elasticity. Every time the encoder 7 rotates by one tooth position, the bent portion 601 of the positioning piece 6 can correspondingly abut against the toothed ring 503 due to its elasticity. Of course, in order to prevent the positioning piece 6 from losing its engagement with the toothed ring 503, the brush table 2 can also form a stop protrusion 201 for abutting against the bent portion 601 of the positioning piece 6.

[0030] Specifically, the base 102 is also equipped with a torsion spring 122 for resetting the brush table 2. The movable end of the torsion spring 122 abuts against the opening groove formed by the brush table 2. The torsion spring 122 will deform due to the downward movement of the brush table 2, and its restoring force can push the brush table 2 back upward, so that the bent part 601 of the positioning piece 6 is locked in the recess of the toothed ring 503.

[0031] Specifically, since the code disk 5 needs to push the brush table 2 to slide within the base 1, in order to avoid interference between its circular protrusion 501 and the upper cover 101, the upper cover 101 is also provided with an oval-shaped clearance hole 111, in which the circular protrusion 501 can move.

[0032] Specifically, the brush 3 is bent upward on the side away from the conducting terminal 112, so that it can contact the code chip 7 embedded in the bottom of the code disk 5.

[0033] Furthermore, one end of the aforementioned conductive terminal 112 is fixed to the outside of the base 102, while the other end is inserted into the base 102.

[0034] Furthermore, the aforementioned dial 4 can be made of PC material. By adjusting different colored powders, when paired with LED lights on the product, the dial 4 can directly produce different color effects due to its light-guiding effect, eliminating the need for painting and saving production costs to a certain extent.

[0035] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
