Description

Technical Field

[0001] This utility model relates to the field of laser pointer technology, specifically a rechargeable storage device that integrates a wireless microphone, a PPT page turner, and a laser pointer. Background Technology

[0002] Laser pointers and microphones are frequently used in scenarios such as classroom teaching, conference room training, and lectures. Currently, the microphone and laser pointer are typically separate devices, which causes inconvenience for users both during and after use. For example, users often need to hold the laser pointer in one hand and the microphone in the other, making handling and operation difficult. Furthermore, after use, the microphone and wireless laser pointer are often stored separately, meaning only one may be found for the next use. There is a lack of a device that can efficiently store both the microphone and laser pointer together.

[0003] Furthermore, existing designs that combine microphones and laser pointers often use a fixed connection method, simply linking the two together. This design often makes it impossible, or even if possible, to remove the microphone when needed (e.g., to take the microphone out and put it to one's mouth to speak).

[0004] Furthermore, microphones and laser pointers often need to be charged after use. The current solution is to use different charging adapters to charge microphones and laser pointers, which also causes inconvenience. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a rechargeable storage device that integrates a wireless microphone, a PPT page turner, and a laser pointer, thereby solving the problems described in the background section.

[0006] The technical solution to achieve the purpose of this utility model is as follows: a rechargeable storage device integrating a wireless microphone, a PPT page turner, and a laser pointer, comprising a housing, a receiving plate, a clip, a microphone, a battery, and a circuit board assembly. The circuit board assembly is mounted on the receiving plate and includes a laser emitter. The receiving plate is slidably mounted in the inner cavity of the housing and can slide along a first direction to an upper limit position and a lower limit position. The clip and the microphone are detachably mounted on the receiving plate. When the receiving plate slides to the upper limit position, both the clip and the microphone are located in the inner cavity of the housing, and the microphone maintains a connection with the battery through the circuit board assembly. When the receiving plate slides to the lower limit position, both the clip and the microphone are located outside the inner cavity of the housing, and the microphone is disconnected from the electrical connection with the battery.

[0007] Furthermore, the clip and microphone have built-in magnets, which are fixedly or detachably mounted on the clip and microphone. The receiving plate is provided with two magnets, corresponding to the magnets on the clip and microphone respectively.

[0008] Furthermore, the receiving plate is provided with a first groove, a second groove, a third groove and a fourth groove. The first groove and the second groove are installed on the front side of the receiving plate, and the third groove and the fourth groove are installed on the back side of the receiving plate. The positions of the first groove and the third groove are corresponding, and the positions of the second groove and the fourth groove are corresponding. A magnet is installed on each of the third groove and the fourth groove. The clip is magnetically installed in the first groove, and the microphone is magnetically installed in the second groove.

[0009] Furthermore, the housing includes an upper cover and a lower cover that are detachably connected together, forming the housing when the upper cover and the lower cover are connected together, and forming an inner cavity inside the housing.

[0010] Furthermore, the receiving plate is also provided with a first pair of suction grooves, in which magnets are installed. The lower cover is provided with a second pair of suction grooves, which are arranged face-to-face with the first pair of suction grooves, and magnets are installed on the second pair of suction grooves.

[0011] Furthermore, a limiting plate is provided on each of the radial sides of the lower cover shell, and the limiting plates are arranged along the axial direction of the lower cover shell. The two limiting plates and the side wall of the lower cover shell each form a guide groove. The upper cover shell has a guide plate on each of its radial sides. The front end of the guide plate extends to form a front extension plate, and the lower end of the front extension plate has a guide limiting groove, which slides and engages with the limiting plate. When the upper cover is installed on the lower cover, the guide limiting groove engages with the limiting plate, and the front plate engages with the guide groove on the lower cover.

[0012] Furthermore, the upper cover is also provided with several perforations and includes several buttons. The buttons are embedded in the housing through the perforations and are connected to the circuit board assembly. The circuit board assembly can respond to the pressing operation of each button to generate a corresponding electrical signal, thereby realizing the function of the laser pointer.

[0013] Furthermore, the upper cover is also provided with a through hole, which is directly opposite the second groove, so that at least part of one end of the microphone located on the second groove is exposed through the through hole. The microphone is provided with a display screen, which is exposed through the through hole.

[0014] Furthermore, the circuit board assembly includes a drive circuit board and an adapter circuit board. The adapter circuit board is electrically connected to the battery. Both the drive circuit board and the adapter circuit board are mounted on the receiving plate. When the receiving plate slides to the upper limit position, the drive circuit board and the adapter circuit board come into contact and maintain an electrical connection. When the receiving plate slides to the lower limit position, the drive circuit board and the adapter circuit board disengage and the electrical connection is broken.

[0015] Furthermore, the driving circuit board includes a circuit board body, and a laser emitter, a charging interface, and two power terminals mounted and electrically connected to the circuit board body. The laser emitter is used to emit laser light, and the charging interface is used to connect an external power source. The adapter circuit board includes a circuit board, two abutting conductive posts and two connecting posts mounted on the circuit board. When the receiving plate slides to the upper limit position, the abutting conductive posts contact the two connecting posts on the drive circuit board respectively. When the receiving plate slides to the lower limit position, the abutting conductive posts and the connecting posts disengage and maintain a distance.

[0016] The beneficial effects of this utility model are as follows: This utility model integrates a microphone and laser pointer together using magnetic attraction or other detachable methods. The microphone can be easily retrieved and stored as needed, and it can also be conveniently clipped onto the user's body using a clip, making it very convenient and improving the user experience. Furthermore, the sliding receiving plate allows for easy insertion and removal of the receiving plate containing the clip and microphone into the cavity (i.e., the inner cavity) of the housing, facilitating easy retrieval during use and providing excellent protection when not in use. By contacting or detaching the contact point, the microphone can be charged as needed, further enhancing the user experience. Attached Figure Description

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 1-8 As shown, a rechargeable storage device integrating a wireless microphone, PPT page turner, and laser pointer includes a housing, a receiving plate 7, a clip (not shown), a microphone (not shown), a battery 3, and a circuit board assembly. The circuit board assembly is mounted on the receiving plate 7 and includes a laser emitter 22. The receiving plate 7 is slidably mounted in the inner cavity of the housing and can slide along a first direction to an upper limit position and a lower limit position. The first direction can be the axial direction (i.e., the length direction) of the housing. The clip and microphone are magnetically attached to the receiving plate 7. When the receiving plate 7 slides to the upper limit position, both the clip and the microphone are located in the inner cavity of the housing, and the microphone maintains a connection with the battery 3 through the circuit board assembly, allowing the battery 3 to charge the microphone. When the receiving plate 7 slides to the lower limit position, both the clip and the microphone are located outside the inner cavity of the housing, i.e., exposed in the inner cavity, and the microphone is disconnected from the battery 3, preventing the battery 3 from charging the microphone.

[0019] Understandably, the clip and microphone can be connected to the receiving plate 7 in other detachable ways, such as through snaps, latches, or other detachable connections. This detachable connection method allows for easy removal and installation of the clip and microphone. For example, when it is necessary to use the microphone separately (e.g., holding the microphone to the mouth with one hand while using a laser pointer with the other), the microphone can be removed from the receiving plate 7. Similarly, when it is necessary to clip the microphone, cable, or other components to the user's clothing, the clip can be removed, and the target object can be clipped to the user's clothing.

[0020] For example, to achieve magnetic attachment, the clip and microphone have built-in magnets, which can be fixedly or detachably mounted on them. The receiving plate 7 has two corresponding magnets, one on the clip and one on the microphone. When the clip is mounted on the receiving plate 7, the magnet on the clip attracts the corresponding magnet on the receiving plate 7, thus securing the clip to the receiving plate. Similarly, when the microphone is mounted on the receiving plate 7, the magnet on the microphone attracts the corresponding magnet on the receiving plate 7, thus securing the microphone to the receiving plate.

[0021] For example, the receiving plate 7 is provided with a first groove 71, a second groove 73, a third groove 79, and a fourth groove 710. The first groove 71 and the second groove 73 are installed on the front side of the receiving plate 7, and the third groove 79 and the fourth groove 710 are installed on the back side of the receiving plate 7. The positions of the first groove 71 and the third groove 79 are corresponding, and the positions of the second groove 73 and the fourth groove 710 are corresponding. A magnet is installed on each of the third groove 79 and the fourth groove 710, so that the clip and the microphone can be magnetically attracted to the first groove 71 and the second groove 73, that is, the clip is magnetically attracted to the first groove 71, and the microphone is magnetically attracted to the second groove 73.

[0022] For example, the housing includes an upper cover 6 and a lower cover 5 that are detachably connected together, forming the housing when the upper cover 6 and the lower cover 5 are connected together, and forming an inner cavity inside the housing.

[0023] For example, the upper cover 6 also has several perforations and includes several buttons 1. The buttons 1 are embedded in the cover through the perforations and connected to the circuit board assembly. The circuit board assembly can respond to the pressing operation of each button 1 to generate a corresponding electrical signal, thereby realizing the function of the laser pointer. For example, the function includes turning pages up and down and emitting a red laser. Turning pages up and down can realize the PPT page turning function. The circuit board assembly and the buttons 1 constitute a PPT page turner.

[0024] For example, the upper cover 6 is also provided with a through hole, which is directly opposite the second groove 73, so that at least a portion of one end of the microphone located on the second groove 73 is exposed through the through hole. When the microphone is equipped with a display screen (such as displaying time and / or the microphone's current battery level), the display screen on the microphone is exposed through the through hole, making it convenient for the user to view the display screen.

[0025] For example, the housing also includes a side cover 8, which covers the rear ends of the upper cover 6 and the lower cover 5.

[0026] For example, the circuit board assembly includes a drive circuit board 2 and an adapter circuit board 4, with the adapter circuit board 4 electrically connected to the battery 3. Both the drive circuit board 2 and the adapter circuit board 4 are mounted on a receiving plate 7; for example, the drive circuit board 2 is mounted on the front of the receiving plate 7, and the adapter circuit board 4 is mounted on the back of the receiving plate 7. When the receiving plate 7 slides to its upper limit position, the drive circuit board 2 and the adapter circuit board 4 come into contact and remain electrically connected. When the receiving plate 7 slides to its lower limit position, the drive circuit board 2 disengages from the adapter circuit board 4, breaking the electrical connection.

[0027] This way, you can control whether to charge the microphone simply by pulling out the receiving plate 7 (i.e., sliding the receiving plate 7), which is very convenient.

[0028] For example, the driving circuit board 2 includes a circuit board body 7221, and a laser emitter 22, a charging interface 23, and two terminals 24 mounted and electrically connected to the circuit board body 7221. The laser emitter is used to emit laser light, the charging interface 23 is used to connect an external power source (such as AC power) to charge the battery 3 or directly charge the microphone, and the two terminals 24 serve as positive and negative terminals. The terminals 24 can be copper terminals.

[0029] The adapter circuit board 4 includes a circuit board 41, and two abutting conductive posts 42 and two connecting posts 43 mounted on the circuit board 41. When the receiving plate 7 slides to the upper limit position, the abutting conductive posts 42 contact the two electrical connection posts 24 on the drive circuit board 2 respectively, so that the drive circuit board 2 and the adapter circuit board 4 are in contact and maintain an electrical connection. When the receiving plate 7 slides to the lower limit position, the abutting conductive posts 42 and the electrical connection posts 24 are disengaged and separated, so that the drive circuit board 2 and the adapter circuit board 4 are disconnected and the electrical connection is broken.

[0030] For example, in order to make the contacting conductive post 42 and the contacting post 24 more firmly in contact, the contacting conductive post 42 and / or the contacting post 24 are flexible members with elastic deformation capabilities, so that the two can make more full contact and thus maintain a more firm contact.

[0031] For example, the receiving plate 7 is further provided with a first pair of suction grooves 78, and a magnet is installed in the first pair of suction grooves 78. The lower cover shell 5 is provided with a second pair of suction grooves 52, which are arranged face to face with the first pair of suction grooves 78, and a magnet is installed in the second pair of suction grooves 52.

[0032] By installing magnets on both the first pair of suction grooves 78 and the second pair of suction grooves 52, it is easier and more convenient to install the receiving plate 7 into place, making the installation easier and less labor-intensive.

[0033] For example, the receiving plate 7 is provided with a column (not shown in the figure), and the column is provided with a column hole 711 adapted to the connecting column 43. The connecting column 43 is inserted into the column hole 711, so that the adapter circuit board 4 is installed on the receiving plate 7.

[0034] For example, the receiving plate 7 is also provided with a longitudinal groove 74, the electrical contact post 24 is embedded in the longitudinal groove 74 and can slide freely along the longitudinal groove 74, and the lower end of the electrical contact post 24 extends out of the longitudinal groove 74 and can contact the abutting conductive post 42.

[0035] For example, the lower cover 5 is provided with a limiting plate 53 on each of its radial sides. The limiting plates 53 are arranged along the axial direction of the lower cover 5, and the two limiting plates 53 and the side wall of the lower cover 5 each form a guide groove 54.

[0036] The upper cover 6 is provided with a guide plate 712 on each of its radial sides. The front end of the guide plate 712 extends to form a front extension plate 75, and the lower end of the front extension plate 75 is provided with a guide limiting groove 76. The guide limiting groove 76 is slidably engaged with the limiting plate 53, so that the receiving plate 7 can slide freely along the limiting plate 53, thereby allowing the receiving plate 7 to slide within the cavity of the housing.

[0037] When the upper cover 6 is installed on the lower cover 5, the guide limiting groove 76 engages with the limiting plate 53, and the front plate 75 engages with the guide groove 54 on the lower cover 5.

[0038] For example, the receiving plate 7 is also provided with a downward protrusion 13, and the lower cover shell 5 is also provided with a limiting block 55. When the receiving plate 7 slides to the downward limit position, the downward protrusion 13 abuts against the limiting block 55, and the limiting block 55 prevents the receiving plate 7 from sliding further. At this time, the receiving plate 7 just reaches the downward limit position to prevent the receiving plate 7 from sliding off the shell.

[0039] For example, the lower cover 5 is further provided with a fifth groove 51, and a magnet is installed in the fifth groove 51. By installing a magnet in the fifth groove 51, it is easy to magnetically attach the wireless laser pointer to an external target object, such as to a metal part, so that it can be placed in a fixed position when not in use.

[0040] For example, one end of the receiving plate 7 is also formed with a notch 77, and the battery 3 is located in the notch 77. The notch 77 facilitates the installation of the battery 3, the drive circuit board 2, and the adapter circuit board 4.

[0041] This invention integrates a microphone and laser pointer using magnetic attraction or other detachable methods, allowing for convenient retrieval and storage of the microphone as needed. The clip can also be easily attached to the user, enhancing usability and improving the user experience. Furthermore, the sliding receiving plate 7 allows for easy insertion and removal of the receiving plate containing the clip and microphone into the housing cavity, facilitating easy access during use and convenient storage when not in use, while also providing excellent protection. The microphone charging can be controlled at any time via contact or detachment, further enhancing the user experience.

[0042] The embodiments disclosed in this specification are merely illustrative of one aspect of the features of this utility model. The protection scope of this utility model is not limited to this embodiment, and any other functionally equivalent embodiments fall within the protection scope of this utility model. Those skilled in the art can make various other corresponding changes and modifications based on the technical solutions and concepts described above, and all such changes and modifications should fall within the protection scope of the claims of this utility model.
