Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to an automobile control switch. Background Art

[0002] There are many small interior switches in the electronic and electrical equipment of the automotive industry. For example, the car window glass lifting switch controls the relative position of the car window glass by pressing and popping up the button. By operating these small switches, the driver can control the corresponding functions of the car under different demand environments. According to the operation form of the switch, the car small switches are mainly direct pressure type, rotary type and toggle type.

[0003] In the prior art, the window switch is generally installed on the door of the car cab and is used to control the door, window, door lock, etc. By pressing or pulling the button, the button column on the button and the contact on the circuit board are in conflict to realize the opening and closing of the window lifter. However, in the existing window switch, the switch button on the assembly used for operation has more or less shaking problems when it is turned, which will cause problems such as poor hand feel and user experience. During the operation, motion interference may occur, resulting in problems such as difficulty in operation, inability to switch the control mode in place, and low operation reliability. What's worse, it may cause the switch button to be misplaced, so that the switch is stuck and can no longer perform its function. Utility Model Content

[0004] Therefore, the technical problem to be solved by the utility model is to overcome the defect of easy shaking and dislocation in the prior art, thereby providing an automobile control switch.

[0005] The above technical objectives of the utility model are achieved through the following technical solutions:

[0006] An automobile control switch, comprising:

[0007] An outer shell, the outer shell comprising an upper shell and a lower shell that are buckled with each other, a cavity is formed between the upper shell and the lower shell, a circuit board assembly arranged along the length direction thereof is installed in the lower shell, a plurality of micro switches are installed on the circuit board assembly, and a plurality of openings for the switch components to extend out are provided on the upper shell;

[0008] A switch assembly, the switch assembly comprising a window lift switch, a vehicle lock switch and a window lock switch, the window lift switches are provided in four and in a rectangular array structure, the window lock switch and the vehicle lock switch are arranged in parallel along the width direction of the upper housing, and the window lift switch, the window lock switch and the vehicle lock switch each correspond to a micro switch;

[0009] A fixing component is arranged in the cavity, and the fixing component includes a toggle fixing part and a push fixing part. The toggle fixing part is arranged on both sides of the window lifting switch, and the push fixing part is arranged in the vehicle lock switch and the window lock switch.

[0010] By adopting the above technical solution, a fixing component is added to achieve stable installation of the switch component, and the problem of shaking and misalignment of the switch component is improved. The toggle fixing part can be toggled up and down on the window lift switch to reduce the shaking of the left and right displacement. The pressing fixing part can avoid the problem of misalignment and jamming caused by the difficulty in resetting after the vehicle lock switch / window lock switch is pressed to the bottom. The fixing component has a simple structure and achieves an obvious fixing effect.

[0011] Furthermore, the toggle fixing member includes a receiving frame and a fixing plate, the fixing plates are symmetrically arranged on both sides of the receiving frame, the fixing plates are clamped with the receiving frame, and positioning grooves are also arranged on the fixing plates on both sides close to the inner wall of the outer shell.

[0012] By adopting the above technical solution, the coordinated arrangement of the accommodating frame and the fixing plate reduces the shaking problem generated when operating the window lift switch, thereby improving the operational reliability of the window lift switch.

[0013] Furthermore, the fixing plate is provided with a receiving slot on one side close to the receiving frame, the receiving frame is provided with a buckle corresponding to the receiving slot, the receiving frame is also provided with a guide piece obliquely and symmetrically, and the fixing plate is provided with a limiting groove corresponding to the guide piece.

[0014] By adopting the above technical solution, the receiving slot and the buckle realize the connection between the receiving frame and the fixed plate. The inclined guide piece has a certain elasticity, which can buffer the partial shaking of the receiving frame with the window lifting switch. The limit groove prevents the receiving frame from being offset too much to cause structural interference.

[0015] Furthermore, a positioning strip extending from the upper shell body is engaged with the positioning slot, protruding blocks are fixed on opposite sides of the positioning strip, a groove is correspondingly provided in the positioning slot, and a trapezoidal limiting plate is vertically provided on the top of the fixing plate.

[0016] By adopting the above technical solution, the positioning strip and the positioning slot are fixed together to realize the installation of the fixing plate, and the groove and the protruding block are matched to further clamp the fixing plate to avoid relative displacement between the fixing plate and the outer shell, which affects the fixation of the fixing plate to the receiving frame, that is, affects the shaking limit of the window lifting switch.

[0017] Furthermore, the push-fixing member includes a symmetrically arranged elastic member and a curved contact piece, the elastic member is arranged on both sides of the micro switch, the contact piece is arranged between the micro switch and the elastic member, and the curved openings of the contact piece are arranged opposite to each other.

[0018] By adopting the above technical solution, the elastic member and the curved contact piece are arranged in coordination, thereby reducing the shaking problem of the vehicle lock switch / window lock switch, and at the same time ensuring the connection stability of the push switch, thereby realizing the vehicle lock / window lock function.

[0019] Furthermore, the elastic member is vertically fixed on the circuit board assembly, and the elastic member includes a push pin and a spring arranged in the push pin. The side of the push pin away from the circuit board assembly abuts against the inner wall of the vehicle lock switch / window lock switch, and the side of the push pin away from the circuit board assembly is arc-shaped.

[0020] By adopting the above technical solution, the setting of the elastic part can ensure that the vehicle lock switch / window lock switch can be reset to the initial position after moving downward. At the same time, the presence of the push pin also prevents the entire switch from being stuck in the opening after being pressed directly to the bottom, thereby reducing the risk of switch displacement and dislocation. The two relatively arranged elastic parts are relatively stable and will not produce large shaking during the switch resetting process, which can improve the problem of excessive shaking.

[0021] Furthermore, the contact piece is arranged on the circuit board assembly, and a contact point is arranged on the contact piece, and the contact piece is connected to the circuit board assembly through the contact point.

[0022] By adopting the above technical solution, in addition to the direct conduction between the micro switch and the circuit board assembly, indirect conduction of the contact piece is also added. When pressing the vehicle lock switch / window lock switch, it is not necessarily located exactly above the micro switch. Therefore, the contact pieces located on both sides of the micro switch can increase the possibilities of signal transmission. When pressing the offset center, the vehicle lock / window lock function can also be realized, thereby ensuring stable transmission.

[0023] Furthermore, a plurality of positioning holes are provided at intervals on the lower end surface of the upper shell, and a positioning column engaged with the positioning hole is provided on the upper end surface of the lower shell, and the positioning column is vertically arranged.

[0024] By adopting the above technical solution, the cooperation of the positioning holes and the positioning posts facilitates the installation and positioning of the upper shell and the lower shell, ensuring the accuracy of the outer shell assembly. At the same time, the positioning holes and the positioning posts are respectively on the upper shell and the lower shell, which is also easy to distinguish.

[0025] In summary, the technical solution of the utility model has the following advantages:

[0026] 1. The automobile control switch provided by the utility model can toggle the fixing part up and down on the window lift switch to reduce the shaking problem. The pressing fixing part can avoid the problem of misalignment and jamming caused by the difficulty in resetting after the vehicle lock switch / window lock switch is pressed to the bottom. The fixing component has a simple structure and obvious effect.

[0027] 2. The automobile control switch provided by the utility model adds a contact piece for conduction, which improves the convenience of pressing the switch. The function can also be realized when the car lock switch / window lock switch is not pressed vertically in the center, meeting the user's timely and fast needs.
