Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electronic products, in particular to a Bluetooth CD player. Background Art
[0002] CD players were once very popular portable audio-visual devices. With the development of Bluetooth technology, traditional CD players have been injected with new technological power. CD players are equipped with a CD door to cover the CD disc. The CD door is usually equipped with a switch arm to cooperate with the blade switch inside the CD player shell to achieve the closing and opening of the CD door; at the same time, the CD door is also equipped with incisors, which cooperate with the resistance wheel inside the shell to achieve the controllable opening and closing speed of the CD door, so as to avoid the CD door being directly bounced open when opening, causing damage to the CD door. However, since the blade switch and incisors are usually made of plastic, material fatigue is inevitable. After a long time of use, the blade switch will become loose, resulting in unstable closing. The incisors will deform, causing the teeth to loosen and cause sweeping problems. Utility Model Content
[0003] The technical problem to be solved by the utility model is to provide an improved structure of a Bluetooth CD player which has a simple structure, a reasonable design, can ensure that the CD door can keep opening and closing normally for a long time, and does not have the problem of tooth scanning.
[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions: an improved structure of a Bluetooth CD player, including a shell, a CD door, an electronic component and a control panel, the CD door is arranged on the shell to cover the CD compartment, and the control panel is arranged on the surface of the shell to realize operation control; incisors and switch arms are respectively arranged near the two sides of the CD door, incisor holes and switch arm holes are arranged on the shell, a resistance wheel is arranged next to the incisor hole to cooperate with the incisor, and a blade switch is arranged next to the switch arm hole to cooperate with the switch arm; the incisor is inserted into the shell through the incisor hole to engage with the resistance wheel, and the switch arm is inserted into the shell through the switch arm hole to dock with the blade switch, characterized in that: a raised support bone position is arranged in the front position of the incisor hole in the shell, and the support bone position abuts against the bottom surface of the incisor to keep the incisor in close engagement with the resistance wheel; a limit bone is arranged in the shell at the position outside the blade switch, and the limit bone abuts against the outer side of the blade switch to form a structure for pushing the blade switch toward the switch arm.
[0005] Furthermore, the support bone is an integral structure with the housing, and the top of the support bone is an arc-shaped structure, which is arranged near the front edge of the incisor hole. The arc-shaped structure of the top of the support bone can better match the arc-shaped bottom surface of the incisor, so that the bottom surface of the incisor slides more smoothly against the support bone, so as to avoid affecting the normal opening and closing of the CD door.
[0006] Furthermore, the limit bone and the shell are an integral structure, and the limit bone is an L-shaped structure, and one side edge of the limit bone abuts against the outer side of the leaf switch, thus having a better abutting force.
[0007] Furthermore, the control panel is arranged on the front side of the shell, and the control panel includes a panel frame and a control circuit board, and control buttons are arranged on the panel frame; the control buttons include two single buttons and two groups of three-button groups, and each button is installed in the panel frame in a left-right symmetrical structure and respectively docked with the switch buttons on the control circuit board.
[0008] Furthermore, the two three-button groups have the same structure and are both U-shaped. A U-shaped connecting bracket is provided between the three buttons. The connecting bracket is connected to the three buttons through three connecting arms to form an integrated structure and is manufactured by one-piece molding.
[0009] Furthermore, the single button is arranged in front of the connecting bracket and passes through the connecting bracket to connect with the switch button on the control circuit board. In this way, the button can be installed in a relatively narrow space through the clever layered design of the connecting bone structure, achieving a compact and simple assembly effect, and making the elastic feel of each button more comfortable.
[0010] The utility model arranges support bones and limit bones at positions near the incisor holes and the blade switch inside the shell respectively, so that the support bones support the bottom surfaces of the incisors, so that the arc-shaped tooth arms of the incisors will not be deformed downward due to pressure during the process of opening and closing the door, thereby avoiding the problem of loose teeth engagement and tooth sweeping; at the same time, the limit bones are used to support the blade switch, so as to solve the problem of abnormal switching caused by material fatigue or loose switch after the switch arm and the blade switch are in contact for a long time.
