Description

Technical Field

[0001] This utility model relates to the field of rotary switches, specifically to a rotary switch for automobiles that prevents accidental activation. Background Technology

[0002] A rotary switch is a common type of electronic switch, mainly composed of a knob, a switching mechanism, and a mounting base. The working principle of a rotary switch is that rotating the knob causes the internal switching mechanism to connect or disconnect the circuit, thereby controlling the switching of electrical appliances.

[0003] In automobiles, rotary switches are mainly used in equipment such as air conditioning and audio systems to adjust functions like fan speed and volume. Because these switches are exposed on the car's center console, children may turn them out of curiosity, or passengers may accidentally touch them, altering the device's functionality and affecting normal use. They can also distract the driver; for example, accidentally pressing the audio switch could cause a sudden increase in volume, compromising driving safety. Utility Model Content

[0004] The purpose of this utility model is to provide an anti-accidental activation automotive rotary switch. This rotary switch can switch between a normal use state and a restricted use state, reducing the risk of the rotary switch being turned due to accidental activation and ensuring safety during driving.

[0005] The technical solution adopted by this utility model to solve the above problems is:

[0006] An anti-accidental activation automotive rotary switch includes:

[0007] The switch body has a knob ring rotatably connected to it;

[0008] A locking element is inserted through the knob ring along the axial direction of the knob ring, and the bottom end of the locking element is slidably connected to the switch body and cannot be rotated.

[0009] The locking member has two locking blocks at opposite positions on its side. The knob ring has a first groove for horizontal sliding of the locking blocks, and a second groove for vertical sliding of the locking blocks at a position opposite to the locking blocks. The locking member and the switch body can be fixed together by the locking mechanism. When the knob ring is in the initial position, the locking blocks are located at the connection between the first and second grooves.

[0010] As a further improvement to the above technical solution, a groove is provided on the end face of the top of the locking member, and a transparent cover is provided on the opening of the groove. A rotating member is rotatably connected in the groove. The rotating member is provided with unlocking and locking marks along its circumference to indicate whether the knob ring is in a rotatable state or a non-rotatable state. When the locking block is located in the first sliding groove, the unlocking mark is exposed on the opening of the groove. A driving mechanism is provided between the rotating member and the switch body. When the locking member slides relative to the switch body, the rotating member rotates relative to the locking member through the driving mechanism.

[0011] As a further improvement to the above technical solution, the driving mechanism includes two driving units, which are symmetrically arranged relative to the rotating part. The driving units and the locking block are arranged alternately at equal angles around the central axis of the locking part. The driving unit includes a connecting member and a driving member. The two connecting members are respectively fixedly connected to both ends of the rotating part. The connecting members are provided with two extension plates arranged at equal angles around the central axis. A torsion spring is provided between the rotating part and the locking part. When the rotating part and the locking part are in a relatively stationary state through the torsion spring, the two extension plates are arranged diagonally and both are perpendicular to the sliding direction of the locking part. The driving member is fixedly connected to the switch body and is located on the sliding trajectory of the extension plate.

[0012] As a further improvement to the above technical solution, the locking mechanism includes two locking rods, which are arranged symmetrically to the locking member. The locking rods are located directly below the corresponding locking blocks. The bottom ends of the locking rods are hinged to the switch body. A guide groove is provided on the side of the locking member for the top end of the locking rod to slide. The guide groove is symmetrical and includes two arc grooves connected at their bottom ends. Two oblique grooves connected at their bottom ends are provided between the top ends of the two arc grooves. The top ends of adjacent arc grooves and oblique grooves are connected. A spring is provided between the bottom end of the locking member and the switch body. The two ends of the spring abut against the locking member and the switch body, respectively.

[0013] As a further improvement to the above technical solution, the knob ring has friction texture on its side.

[0014] Compared with the prior art, this utility model has the following advantages and effects:

[0015] This invention achieves the goal of restricting the rotation of the knob ring by the locking component through the structural arrangement between the locking component and the knob ring. Combined with the locking mechanism's locking effect between the locking component and the switch body, it is possible to switch the knob switch between normal use and restricted use, thereby reducing the risk of the knob switch rotating due to accidental contact and ensuring safety during driving.

Detailed Implementation

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0024] See Figures 1-6 This embodiment provides an anti-accidental activation automotive rotary switch, comprising a switch body 1 and a locking member 2. A rotary ring 3 is rotatably connected to the switch body 1. The locking member 2 passes through the rotary ring 3 along its axial direction. The bottom end of the locking member 2 is slidably connected to the switch body 1 and cannot be rotated. Locking blocks 21 are provided at two opposite positions on the side of the locking member 2. A first groove 22 is provided on the rotary ring 3 for horizontal sliding of the locking blocks 21. A second groove 23 is provided on the first groove 22 at a position opposite to the locking blocks 21 for vertical sliding of the locking blocks 21. The locking member 2 and the switch body 1 can be fixed together by a locking mechanism 4. When the rotary ring 3 is in its initial position, the locking blocks 21 are located at the connection between the first groove 22 and the second groove 23.

[0025] When the locking member 2 is not sliding relative to the switch body 1, the locking block 21 is located in the first slide groove 22, and the locking member 2 and the switch body 1 are in a relatively stationary state through the locking mechanism 4. The knob ring 3 can rotate relative to the switch body 1, thereby achieving the effect of controlling the switch position by rotating the knob ring 3. At this time, the switch can be used normally. When the knob ring 3 is in the initial position, pressing the locking member 2 downward causes the locking block 21 to move from the first slide groove 22 into the second slide groove 23, so that the locking member 2 restricts the rotation of the knob ring 3 relative to the switch body 1. At this time, the switch cannot be used, and when the locking member 2 slides to the bottom relative to the switch body 1, the two can be fixed together by the locking mechanism 4.

[0026] In this embodiment, changing the contact or separation between the contacts inside the switch body 1 by rotating the knob ring 3 is a known structure in existing conventional knob switches, and the specific structure will not be described in this embodiment.

[0027] See Figure 1 The knob ring 3 has friction texture 5 on its side, which helps to increase the friction between the finger and the knob ring 3, thereby ensuring the effectiveness of rotating the knob ring 3.

[0028] See Figure 2 , Figure 3 The locking member 2 has a groove 6 on its top end face, and a transparent cover 61 is provided on the opening of the groove 6. A rotating member 7 is rotatably connected in the groove 6. The rotating member 7 has an unlock mark 71 and a locking mark 72 along its circumference to indicate whether the knob ring 3 is in a rotatable state or a non-rotatable state. When the locking block 21 is located in the first slide groove 22, the unlock mark 71 is exposed on the opening of the groove 6. A driving mechanism 8 is provided between the rotating member 7 and the switch body 1. When the locking member 2 slides relative to the switch body 1, the rotating member 7 rotates relative to the locking member 2 through the driving mechanism 8.

[0029] When the switch is in normal working order, the unlock mark 71 is visible in the groove 6. When the locking member 2 slides relative to the switch body 1, causing the knob ring 3 to be restricted from rotation by the locking member 2, the switch body 1 drives the rotating member 7 to rotate relative to the locking member 2 through the drive mechanism 8, so that the mark visible in the groove 6 changes from the unlock mark 71 to the lock mark 72. This makes the switch's usage status intuitively visible and improves the convenience of use.

[0030] In this embodiment, the unlocking mark 71 is represented by the symbol "ON", and the locking mark 72 is represented by the symbol "OFF".

[0031] See Figure 4The driving mechanism 8 includes two driving units 81, which are symmetrically arranged relative to the rotating member 7. The driving units 81 and the locking block 21 are arranged alternately at equal angles around the central axis of the locking member 2. The driving unit 81 includes a connecting member 82 and a driving member 83. The two connecting members 82 are respectively fixedly connected to both ends of the rotating member 7. The connecting member 82 is provided with two extension pieces 84 arranged at equal angles around its central axis. A torsion spring is provided between the rotating member 7 and the locking member 2. When the rotating member 7 and the locking member 2 are in a relatively stationary state through the torsion spring, the two extension pieces 84 are arranged diagonally and both are perpendicular to the sliding direction of the locking member 2. The driving member 83 is fixedly connected to the switch body 1 and is located on the sliding trajectory of the extension piece 84. When the locking member 2 slides relative to the switch body 1, the extension piece 84 gradually approaches and abuts against the driving member 83, and under the restraint of the driving member 83, the connecting member 82 drives the rotating member 7 to rotate relative to the locking member 2, thereby changing the exposed mark in the groove 6.

[0032] See Figure 5 , Figure 6 The locking mechanism 4 includes two locking rods 41, which are symmetrically arranged relative to the locking member 2. The locking rods 41 are located directly below the corresponding locking blocks 21. The bottom end of the locking rods 41 is hinged to the switch body 1. The side of the locking member 2 is provided with a guide groove 42 for the top end of the locking rods 41 to slide. The guide groove 42 is symmetrical and includes two arc grooves 43 connected at their bottom ends. There are two oblique grooves 44 connected at their bottom ends between the top ends of the two arc grooves 43. The top ends of adjacent arc grooves 43 and oblique grooves 44 are connected. A spring 45 is provided between the bottom end of the locking member 2 and the switch body 1. The two ends of the spring 45 abut against the locking member 2 and the switch body 1, respectively.

[0033] When the knob ring 3 and the locking member 2 are in the unlocked state, the spring 45 is in an uncompressed state, and the top of the locking rod 41 is located on the locking position 46 formed by the connection of the bottom ends of the two arc grooves 43. When the locking member 2 is pressed down, the locking block 21 enters the second slide groove 23, the knob ring 3 and the locking member 2 are in the locked state and the spring 45 is compressed. At the same time, the top of the locking rod 41 moves upward along the arc groove 43 to the bottom. When the locking member 2 is stopped, the locking member 2 moves upward due to the force of the spring 45 returning to its original state. At this time, the top of the locking rod 41 enters the locking position 46 formed by the connection of the bottom ends of the two arc grooves 44 along the inclined groove 44. The locking member 2 and the switch body 1 are in a relatively stationary state.

[0034] Press the locking member 2 down again, so that the top of the locking rod 41 moves diagonally upward along the inclined groove 44 to the bottom. When the pressing of the locking member 2 stops, the locking member 2 moves upward due to the force of the spring 45 returning to its original state, so that the top of the locking rod 41 moves downward along the arc groove 43 into the locking position 46 formed by the connection of the bottom ends of the two arc grooves 43. At this time, the locking block 21 moves into the first sliding groove 22, and the knob ring 3 and the locking member 2 are in the unlocked state.

[0035] The above description in this specification is merely illustrative of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
