Description
Technical Field
[0001] This utility model relates to the field of Bluetooth backplanes, and more particularly to a Bluetooth speaker motherboard mounting structure for multi-device switching. Background Technology
[0002] A Bluetooth backplane is a circuit board that integrates a Bluetooth function module and is the core component for enabling Bluetooth wireless communication in devices. It can connect to Bluetooth devices such as headphones, keyboards, and speakers, transmitting data and audio signals. It features low power consumption and anti-interference capabilities and is widely used in mobile phones, computers, smart home devices, and other applications, providing convenient wireless connectivity and simplifying the connection process between devices.
[0003] A search revealed patent publication number CN202122426838.5, which discloses a Bluetooth speaker supporting multi-functional four-dimensional stereo spectrum lighting effects. This relates to the field of Bluetooth speaker technology, specifically a Bluetooth speaker supporting multi-functional four-dimensional stereo spectrum lighting effects, comprising a main housing, a protective housing, and a circuit board. The protective housing has annular holes for positioning. In this Bluetooth speaker supporting multi-functional four-dimensional stereo spectrum lighting effects, the circuit board can be fixed inside the main housing using positioning bolts on the surface of the protective housing, avoiding the instability caused by snap-fit fixing. The protective housing facilitates protection of the circuit board and also allows for easy disassembly and maintenance. The shock-absorbing plate uses the force of a compression spring to dampen and buffer the circuit board, reducing impact damage and increasing the device's lifespan. The auxiliary cylinder limits the compression spring to prevent displacement, and the protective cover protects the protective housing and the speaker, making it convenient to use.
[0004] While existing technologies can achieve certain Bluetooth speaker baseboard performance, they suffer from a drawback: the lack of a quick-switch function for connection port positions prevents the baseboard from adapting to various data cables for signal transmission, thus affecting performance. Therefore, we propose a multi-device switching Bluetooth speaker motherboard mounting structure that solves this problem. Utility Model Content
[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a Bluetooth speaker motherboard installation structure for multi-device switching.
[0006] The technical solution of this utility model is as follows: A Bluetooth speaker motherboard mounting structure for multi-device switching includes a base plate, a turntable, a connector, and a mounting base. The base plate has a turntable at its upper end, and the upper end of the turntable has wiring ports arranged in a ring array. The inner side of each wiring port has a second contact, and the upper end of the second contact has a first contact. A connector is rotatably mounted in the middle of the turntable. The connector is fixed to the base plate and electrically connected. A mounting base is fixed on one side of the turntable, and a limiting block with an elastic element is inserted into the mounting base.
[0007] When in use, the base plate can be installed inside the Bluetooth device, and an opening is made on the edge to allow the protruding part of the turntable to extend. Manually rotating the turntable allows different wiring ports to be aligned with the opening. Each wiring port has a different model, achieving a switching effect. After rotation, the limit block can restrict the rotation of the turntable under the action of spring two (manual drive allows rotation). The connector is electrically connected to the base plate and to each wiring port. The positive and negative terminals are electrically connected using brush one and brush two. The overall device is ingeniously and simply designed, stable and reliable, and can achieve the effect of switchable connectors, making it highly practical.
[0008] Preferably, the limiting block has an internal mounting groove, and the mounting groove has a second spring. One end of the second spring is fixedly connected to the inner wall of the mounting groove, and the other end is fixedly connected to the outer wall of the mounting base. Under the action of the second spring, the limiting block and the groove can be engaged, so that the turntable will not rotate under small vibrations.
[0009] Preferably, the turntable surface is provided with grooves arranged in a circular array. The grooves are used for engaging the limiting block, and the grooves can restrict the rotation of the turntable after the limiting block is inserted.
[0010] Preferably, a brush one is inserted into one side of the connector, and a brush two is provided at the lower end of the brush one. A mounting plate is provided on the outer wall of the brush one and the brush two. A spring one is fixed to the outer wall of one side of the connector on the mounting plate. The brush one and the brush two are positive and negative poles, respectively, which can be used to electrically connect the wiring port to the connector to achieve signal transmission.
[0011] Preferably, the first brush and the second brush are electrically connected to the first contact and the second contact, respectively. The connection between the first brush and the second brush ensures the effectiveness of the electrical connection and eliminates the need for wires, thus preventing the problem of wire tangling during the rotation of the turntable.
[0012] Preferably, the first and second contacts are divided into five, and each is electrically connected to one of the five terminals. There is a gap between the first and second contacts in different areas laterally. The contact points of the first and second contacts are insulated. The gaps can prevent electrical conduction between adjacent first and second contacts, thus preventing the normal use of the terminals.
[0013] Preferably, the head of the limiting block is designed as an isosceles triangle, and one side of the turntable protrudes 3 millimeters from the edge of the base plate. The protruding turntable makes it convenient for the user to manually rotate it, and the isosceles triangle design of the limiting block head can ensure that the turntable will not jam when rotating forward or backward.
[0014] Compared with existing technologies, the advantages of this utility model are:
[0015] I. This utility model consists of a base plate, a turntable, a connector, and a mounting base. The turntable at the upper end of the base plate can accommodate five different types of wiring ports and can be connected to external signal lines. Rotating the turntable can switch the wiring ports, and the position of the turntable is fixed by a limit block with elastic design.
[0016] Second, based on the first beneficial effect, in order to prevent the wire harness from getting tangled when the turntable rotates, a mode in which brush one and brush two cooperate with contact one and contact two is designed. This allows the device to make electrical connection with the connector when the terminal is rotated to one side without the need for wires. This device has the function of convenient interface switching and has high practicality.
[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
