Description

Technical Field

[0001] The utility model relates to the technical field of automobile combination switches, in particular to an injection-molded automobile combination switch. Background Art

[0002] A combination switch is a device mounted on the steering column of a car, consisting of two or more switches used to control the car's lights, signals, and electrical components. Automotive combination switches have evolved from simple assembly modules to multifunctional integrated modules that share vehicle interfaces and electronics. They have expanded from simple body control functions to include entry systems and auxiliary functions that ensure comfortable operation. However, existing combination switches are often located behind the steering wheel, making them difficult to view and prone to accidental activation.

[0003] Application number 201920037907.3 discloses an automotive combination switch, comprising: a main shaft fixing body having a supporting platform and a fixed shaft; a flexible flat cable fixed to the main shaft fixing body, having a main body, a first cable routing portion, and a second cable routing portion; a rotating body sleeved on the fixed shaft; a spring fixed to the rotating body and located between the rotating body and the first cable routing portion, driven by the rotating body to rotate on the first cable routing portion; a button body disposed on the rotating body and sleeved on the fixed shaft, the second cable routing portion extending from the main body to the top of the button body; a fixing member fixed to the fixed shaft by the central portion of the button body and the rotating body to limit the axial movement of the button body and the rotating body along the fixed shaft. The above-mentioned automotive combination switch integrates the circuit board on the flexible flat cable, and the circuit board is fixed in two sections to the main shaft fixing body and the button body, respectively, which saves space and facilitates installation.

[0004] The above document discloses an automobile combination switch that integrates a circuit board on a flexible flat cable. The circuit board is divided into two sections and fixed on the main shaft fixing body and the button body respectively. This saves space and is convenient for installation. However, its design position is not convenient for observation and is prone to accidental touch.

[0005] It can be seen from this that the existing automobile combination switch does not have the functions of convenient observation and preventing accidental touch, and it is necessary to improve the existing deficiencies and provide a function that can facilitate observation and prevent accidental touch.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1 - Figure 6 As shown, the utility model is an injection-molded automobile combination switch, comprising a steering wheel assembly 1, the steering wheel assembly 1 comprising a steering wheel support 104, an adjusting dial assembly 2 mounted above the steering wheel support 104, a steering wheel cover assembly 3 mounted above the adjusting dial assembly 2, the adjusting dial assembly 2 comprising an adjusting dial body 201, a positioning disk 203 fixedly connected to the top of the adjusting dial body 201, a surface of the positioning disk 203 having a plurality of grooves arranged evenly in a circular pattern, a positioning bead 204 movably connected to the inside of the groove, a circular protrusion 206 fixedly connected to the bottom of the adjusting dial body 201, a movable contact piece 207 provided on the side of the circular protrusion 206, and a mounting groove 205 provided in the middle of the adjusting dial assembly 2. The purpose of this arrangement is that when different functions of the combination switch need to be used, it can be done by rotating the adjustment dial body 201. When the adjustment dial body 201 is rotated, the movable contact 207 will be matched with different fixed contacts 108 under the drive of the adjustment dial body 201, thereby starting different functions. During the rotation of the adjustment dial body 201, the positioning bead 204 will slide along the slide groove 303. When sliding to the position where the positioning groove 304 is located, the positioning bead 204 will sink into a part, thereby achieving the switching and fixing of different functions.

[0028] The outer wall of the adjusting dial body 201 is evenly provided with anti-skid grooves 202. The purpose of such arrangement is that the anti-skid grooves 202 on the surface of the adjusting dial body 201 can increase the friction between the finger and the adjusting dial body 201, making it convenient to adjust.

[0029] The steering wheel assembly 1 includes a steering wheel 101 , which is horizontally connected to the outside of a steering wheel support 104 via two transverse support rods 102 and one longitudinal support rod 103 . A plurality of fixed contact pieces 108 are evenly arranged around the inner wall of the steering wheel support 104 .

[0030] The steering wheel assembly 1 includes a limit block 106 , a limit slot 107 is defined in the middle of the limit block 106 , and the limit slot 107 is fixedly connected to the interior of the steering wheel support 104 via four connecting rods 105 .

[0031] The steering wheel cover assembly 3 includes a steering wheel cover 301. The upper surface of the steering wheel cover 301 is evenly arranged with a plurality of indicator lights 302 arranged in a circular pattern. The lower surface of the steering wheel cover 301 is provided with a circular slide 303. The slide 303 is evenly provided with a plurality of positioning grooves 304. The middle part of the lower surface of the steering wheel cover 301 is connected to a fixing rod 305. The middle part of the fixing rod 305 is provided with a connecting hole 306. The purpose of this arrangement is that when switching to a certain function, the corresponding indicator light (302) will light up immediately, making it easier for the user to clearly understand the function being used.

[0032] The number of fixed contacts 108 , positioning beads 204 , positioning slots 304 and indicator lights 302 is related to the number of functions controlled by the combination switch.

[0033] During installation, first place the adjustment dial assembly 2 above the steering wheel support 104, then align the fixing rod 305 with the installation slot 205 in the middle of the adjustment dial assembly 2 and pass it directly through. The end of the fixing rod 305 is clamped in the limit slot 107. The connection hole 306 in the middle of the fixing rod 305 can be used for the wires connecting the indicator light 302 to pass through and connect to the vehicle circuit.

[0034] When different functions of the combination switch need to be used, it can be done by rotating the adjustment dial body 201. The anti-slip groove 202 on the surface of the adjustment dial body 201 can increase the friction between the finger and the adjustment dial body 201, making it convenient to adjust. When the adjustment dial body 201 is rotated, the movable contact piece 207 will be matched with different fixed contacts 108 under the drive of the adjustment dial body 201, thereby starting different functions. During the rotation of the adjustment dial body 201, the positioning bead 204 will slide along the slide groove 303. When it slides to the position where the positioning groove 304 is located, the positioning bead 204 will sink into a part, thereby achieving the switching and fixing of different functions.

[0035] When a certain function is switched to, the corresponding indicator light (302) will light up immediately, making it easier for the user to clearly understand the function being used.
