Abstract
Description
Technical Field
[0001] This utility model relates to the field of voice recorder charging dock design, and in particular to a charging structure for a voice recorder charging dock. Background Technology
[0002] A voice recorder is a portable electronic device used for recording audio, suitable for scenarios such as meeting minutes, class notes, interviews, evidence collection, and language learning. Many voice recorders nowadays are rechargeable and come with a charging dock. The voice recorder can be charged by placing it on the charging dock and contacting the charging terminals on the dock.
[0003] Most existing voice recorder charging docks use pogo pins as their charging terminals. A pogo pin typically includes a pin shaft, a spring, and a pin tube. The pin tube has a groove, and the pin shaft is linearly movable within the groove. The spring is also located in the groove and connected to the pin shaft. When the charging contacts on the voice recorder can contact the pogo pin for charging, the spring's elasticity effectively maintains contact between the pin shaft and the voice recorder's charging contacts, ensuring charging continues.
[0004] However, in conventional voice recorder charging docks, the pogo pins that serve as charging terminals often experience multi-directional forces when the voice recorder is placed on the dock. This can cause the pin shaft to shift, resulting in excessive contact between the pin shaft and the needle tube, leading to excessive friction. Ultimately, this can cause the pin shaft to jam, and it can also cause the spring connected to the pin shaft to shift, affecting the spring force. In severe cases, it can even cause irreversible deformation of the spring. Utility Model Content
[0005] The purpose of this invention is to provide a charging structure for a voice recorder charging dock that can solve one or more of the above-mentioned problems.
[0006] According to one aspect of this utility model, a charging structure for a voice recorder charging dock is provided, including a voice recorder base, a connecting terminal, a contact terminal, a charging mechanism, and a base.
[0007] Both the voice recorder stand and the charging mechanism are fixedly mounted on the base, and the voice recorder stand is provided with a receiving cavity.
[0008] The connecting terminal includes a ball, a movable terminal, a terminal base, and a spring. The terminal base has a groove, and the ball, movable terminal, and spring are all disposed in the groove and can move along the groove. The ball can also rotate within the groove. One end of the spring abuts against one side of the movable terminal, and the other end abuts against the terminal base. The other end of the movable terminal abuts against the ball. The movable terminal is electrically connected to the charging mechanism.
[0009] The recording pen holder has a through hole that communicates with the receiving groove. The contact terminal is slidably disposed in the through hole. The contact terminal abuts against the ball and can extend into the receiving cavity.
[0010] The beneficial effects of this utility model are as follows: The receiving cavity on the recorder holder of this utility model can be used to receive the recorder. After the recorder is received, the charging contacts on the recorder can abut against and electrically connect with the contact terminal, thereby enabling the charging mechanism to charge the recorder. The spring in the connecting terminal can effectively maintain the connection between the charging contacts and the contact terminal of the recorder. Furthermore, the connecting terminal of this utility model is provided with a ball bearing. When the recorder is placed into the receiving cavity, even if the connecting terminal is subjected to multi-directional forces instantaneously, the forces will only cause the ball bearing to rotate, except for linear movement within the groove. This effectively prevents the movable terminal from moving within the groove in any way other than linear movement, thus effectively preventing positional displacement of the movable terminal, effectively ensuring the working stability of the spring, and preventing jamming or other phenomena that may occur when the movable terminal moves.
[0011] In some embodiments, the recording pen holder has a recess, the through hole is disposed in the recess, and the contact terminal has a protrusion that is slidably disposed in the recess. The recess and protrusion guide the movement of the contact terminal, reducing positional displacement that occurs when the contact terminal moves.
[0012] In some embodiments, the terminal block has an opening at the end of the groove, the diameter of which is smaller than the diameter of the ball. The opening allows a portion of the ball to protrude from the groove, facilitating contact between the ball and the contact terminal. At the same time, limiting the size of the opening prevents the ball from accidentally dislodging from the terminal block.
[0013] In some embodiments, the charging mechanism includes a battery and a PCBA, the battery being connected and electrically connected to the PCBA, and the PCBA being connected and electrically connected to a movable terminal.
[0014] In some embodiments, the base has a first frame, and the battery is embedded in the first frame. The first frame facilitates the installation and fixation of the battery on the base.
[0015] In some embodiments, the base is provided with support columns, and there are multiple support columns. The PCBA is mounted on the support columns and connected to them. The support columns facilitate the connection of screws, thereby facilitating the fixing and installation of the PCBA on the base using screws.
[0016] In some embodiments, the base has a second frame, and the voice recorder holder is embedded in the second frame. The second frame facilitates the installation and fixation of the voice recorder holder on the base.
[0017] In some embodiments, the terminal block includes a first segment and a second segment connected together. The base is provided with a bracket, the first segment is embedded in the bracket, and the second frame is provided with a side groove, in which the second segment is embedded. Setting the terminal block into multiple segments facilitates better identification of the terminal block's installation direction, improves installation efficiency, and the bracket and side groove facilitate the installation and fixation of the terminal block on the base.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings.
[0026] refer to Figures 1-6 The present invention relates to a charging structure for a voice recorder charging base, comprising a voice recorder base 1, a connecting terminal 2, a contact terminal 3, a charging mechanism 4, and a base 5.
[0027] The charging mechanism 4 is fixedly mounted on the base 5. Specifically, the charging mechanism 4 includes a battery 41 and a PCBA 42. The PCBA 42 is connected to the battery 41 by wires and is electrically connected to it. After connection, the PCBA 42 can be used to control the switching of the battery 41.
[0028] The base 5 is provided with a first frame 51, and the battery 41 is fixedly embedded in the first frame 51 by a snap-fit, so that the battery 41 can be fixedly installed on the base 5.
[0029] The base 5 is also provided with a support column 52, which can be multiple. The PCBA 42 is mounted on the support column 52 and fixedly connected to the support column 52 by screws, so that the PCBA 42 can be fixedly installed on the base 5.
[0030] The voice recorder holder 1 is fixedly installed on the base 5 by screws. The base 5 is provided with a second frame 53. The voice recorder holder 1 is fixedly embedded in the second frame 53. The voice recorder holder 1 is provided with a receiving cavity 11, which can be used to receive the voice recorder.
[0031] The connecting terminal 2 includes a ball 21, a movable terminal 22, a terminal base 23, and a spring 24. The terminal base 23 has a groove 231 in which the ball 21, the movable terminal 22, and the spring 24 are all disposed. The groove 231 is preferably a straight groove, and the ball 21, the movable terminal 22, and the spring 24 can all move linearly along the groove 231, and the ball 21 can also rotate in the groove 231.
[0032] One end of the spring 24 abuts against one side of the movable terminal 22, and the other end of the spring 24 abuts against the bottom of the groove 231 of the terminal block 23. The other end of the movable terminal 22 abuts against the ball 21. The movable terminal 22 is connected to the PCBA 42 of the charging mechanism 4 through a wire and thus makes it electrically connected.
[0033] The terminal block 23 has an opening at the end of the groove 231. The diameter of the opening is smaller than the diameter of the ball 21, so as to effectively prevent the ball 21 from falling out of the groove 231.
[0034] The terminal block 23 includes a first segment 232 and a second segment 233. The first segment 232 and the second segment 233 are integrally connected. The base 5 is also provided with a bracket 54. The first segment 232 is embedded in the bracket 54. The second frame 53 is provided with a side groove 531. The second segment 233 is embedded in the side groove 531, so that the terminal block 23 can be fixed on the base 5.
[0035] The side of the recording pen holder 1 is provided with a recess 12, and the middle of the recess 12 is provided with a through hole 13. The through hole 13 is connected to the receiving cavity 11. The contact terminal 3 is slidably disposed in the through hole 13. The contact terminal 3 is also provided with a protrusion 31, which is slidably disposed in the recess 12. The contact terminal 3 can slide into the receiving cavity 11.
[0036] The contact terminal 3 abuts against the ball 21, thereby making the contact terminal 3 and the ball 21 electrically connected.
[0037] When in use, the charging structure of this voice recorder charging dock allows the voice recorder to be placed into the receiving cavity 11, so that the voice recorder charging contact 10 on the voice recorder can abut against the contact terminal 3, and the contact terminal 3 can be slightly retracted under force. The retraction of the contact terminal 3 causes the ball bearing 21 that abuts against it to retract, and the retraction of the ball bearing 21 can drive the movable terminal 22 to retract, so the spring 24 can be compressed to a certain extent. When the elastic force of the spring 24 and the retraction force on the movable terminal 22 are balanced, the current position of the movable terminal 22 can be maintained, that is, the positions of the ball bearing 21 and the contact terminal 3 are also maintained. In other words, the elastic force of the spring 24 can effectively maintain the effective abutment between the voice recorder charging contact 10 and the contact terminal 3. At this time, the voice recorder charging contact 10 can be electrically connected to the charging mechanism 4 in sequence through the contact terminal 3, the ball bearing 21 and the movable terminal 22, and the battery 41 on the charging mechanism 4 can charge the voice recorder.
[0038] Furthermore, during the process of inserting the recorder into the receiving cavity 11, due to the uncertainty of the insertion direction, the force transmitted by the recorder to the ball bearing 21 not only causes the ball bearing 21 to retract but also causes it to rotate until this additional force is stopped. The rotation of the ball bearing 21 effectively prevents the movable terminal 22 from moving within the groove 231 except for linear movement, thus effectively preventing positional displacement of the movable terminal 22, ensuring the working stability of the spring 24, and preventing jamming or other phenomena that may occur during the movement of the movable terminal 22.
[0039] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
