Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electronic switch, in particular to a dial switch for automobile. BACKGROUND

[0002] In the automobile electronic control system, the dial switch as an important manual control component is widely used in the scene of function mode switching, parameter setting, etc. To meet the demand of integrated design, part of the dial switch for automobile adopts the structure integrated with the lamp holder, realizes the state indication function through the lamp holder, and installs the dial switch and the lamp holder as a whole on the base to form a compact control unit.

[0003] However, the existing dial switch integrated with the lamp holder still has many deficiencies in practical application: first, it is difficult to balance the convenience of assembly and disassembly and the tightness of connection. At present, the integrated structure of the dial switch and the lamp holder is mostly installed on the base through threaded connection or buckle connection. If threaded connection is adopted, although the tightness of connection can be ensured, tools or multiple rotations are needed during disassembly, which is tedious to operate, especially in the scene where the function needs to be frequently switched, which seriously affects the efficiency. If buckle connection is adopted, although quick assembly and disassembly can be realized, the buckle is prone to fatigue and loss of elasticity after long-term use, resulting in loose connection and failure to ensure the tight fit of the dial switch and the base, thereby affecting the stability of circuit contact.

[0004] Secondly, there is no clear prompt for screwing into place. When the dial switch is installed on the base by screwing, it is often difficult for the user to judge whether it has been screwed into place. If not screwed enough, it will lead to loose connection and be easily affected by vibration. If it is over-screwed, it will cause thread slipping or component deformation, shorten the service life of the product, and increase the difficulty of subsequent disassembly.

[0005] Thirdly, the vibration during automobile driving easily leads to loose connection. The automobile will produce continuous vibration during driving, and the connection structure of the existing dial switch and the base cannot effectively cope with such vibration. The vibration will gradually weaken the fastening force of the connection, resulting in a gap between the dial switch and the base, which not only affects the stable conduction of the circuit, but also produces abnormal noise due to the friction between the components, and even causes functional failure, which brings hidden dangers to driving safety.

[0006] Therefore, a dial switch for automobile is proposed to solve the above problems. SUMMARY

[0015] The third component is used for converting the vibration force into a fastening force to improve the fastening force between the dial switch and the base in the vibration process of automobile driving.

[0016] As preferred, the third component comprises: a function cavity formed in one side of the positioning body B away from the installation unit, a sliding groove is formed in the surface of the positioning body B on both sides of the function cavity, an electromagnetic stone is fixedly connected to the cavity wall in the function cavity, a mouth-shaped function body is slidingly connected in the sliding groove, a function spring is arranged in the mouth-shaped function body, and the function spring is fixedly connected to the inner cavity of the function cavity at both ends.

[0017] As preferred, the electromagnet is electrically connected with an external controller, and the mouth shape functional body is internally provided with a magnet near one end of the electromagnet.

[0018] As preferred, the functional spring is fixedly connected with a counterweight in the middle, the counterweight is slidably connected in the mouth shape functional body, the mouth shape functional body is fixedly connected with a resisting column at one end away from the electromagnet, the mouth shape functional body is fixedly connected with a fitting body on one side away from the electromagnet, and the fitting body is slidably inserted in the fitting cavity.

[0020] Compared with the prior art, the present application provides a dial switch for a car, which has the following beneficial effects: 1. Through the setting of the first assembly, the rotation of the screwing unit causes the abutment of the abutment body A and the positioning body A with the abutment body B and the positioning body B, respectively, and the abutment of the abutment body A and the positioning body A with the abutment body B and the positioning body B, respectively. In the process of assembly and disassembly, no additional tools are needed, and the dial switch and the base can be installed or disassembled by simple operation, greatly improving the operation efficiency, especially suitable for scenes that need to frequently switch functions. At the same time, by using the insertion force of the positioning body A and the positioning body B with the abutment body A and the abutment body B in the installation process, the abutment connection between the screwing unit and the installation unit is more closely connected when the installation is completed. The flat surface of the positioning body B and the positioning body A makes the sliding connection of the two flat surfaces when the screwing unit is installed on the base in alignment with the adaptive slot, which assists the stability of the installation and avoids the situation that the installation is skewed during the installation process, resulting in unstable falling in the subsequent process.

[0021] 2. Through the setting of the second assembly, the insertion slot is used in cooperation with the second assembly. When the screwing unit and the installation unit are installed and screwed in place, the insertion body is inserted into the insertion slot to provide resistance to the movement of the screwing unit, so as to clearly inform the operator with a clear touch signal. The problem of loose connection caused by insufficient screwing in the traditional structure is effectively avoided, and the deformation of the parts caused by excessive screwing is also avoided. This setting not only ensures the reliability of the connection between the dial switch and the base, prolongs the service life of the product, but also reduces the difficulty of subsequent disassembly and improves the operation experience of the user.

[0022] 3. Through the setting of the third assembly, when vibration occurs during the driving of the automobile, the vibration force is transmitted to the counterweight to make it move up and down, and the vibration force is converted into driving force, the movement of the trigger-shaped functional body is triggered by the movement of the inclined surface of the counterweight, and then the tightness of the connection between the fitting body and the fitting cavity is controlled, the vibration force is converted into the fastening force between the dial switch and the base, and the energy generated by the vibration makes the connection between the dial switch and the base more firm, instead of being loose due to vibration as in the traditional structure, this feature ensures that the dial switch always maintains close contact with the base during long-term use, avoiding problems such as poor circuit contact and component friction noise caused by gaps, significantly improving the stability and reliability of the product in a vibrating environment, and providing a strong guarantee for driving safety.

[0023] 4. Through the setting of the overall assembly, the connection between the positioning body A and the positioning body B is limited from different directions through the cooperation of components such as the plug-in body and the plug-in slot, the fitting body and the fitting cavity, forming a multiple anti-reverse mechanism, avoiding the reverse rotation of the screwing unit and the dismounting of the mounting unit, effectively resisting the reverse rotation force that the screwing unit and the dial switch may be subjected to during the driving of the automobile, even if a certain limiting component is slightly worn or its performance is attenuated due to long-term use, the limiting components in other directions can still play a role, avoiding loosening of the connection part due to reverse rotation, fundamentally eliminating the risk of dismounting, and greatly improving the reliability of the overall installation of the dial switch, ensuring that it always maintains a stable installation state during the entire life cycle of the automobile.

[0048] The third component comprises a function cavity 41 opened in the side of the positioning body B 27 away from the installation unit 13, a sliding groove 42 is opened on the surface of the positioning body B 27 on both sides of the function cavity 41, an electromagnetic stone 43 is fixedly connected to the cavity wall in the function cavity 41, a mouth-shaped functional body 44 is slidingly connected in the sliding groove 42, a functional spring 45 is arranged in the mouth-shaped functional body 44, and the two ends of the functional spring 45 are respectively fixedly connected to the inner cavity of the function cavity 41.

[0049] The electromagnetic stone 43 is electrically connected to an external controller, and a magnet is built-in at the end of the mouth-shaped functional body 44 close to the electromagnetic stone 43.

[0050] A counterweight 46 is fixedly connected to the middle of the functional spring 45, the counterweight 46 is slidingly connected in the mouth-shaped functional body 44, a contact column 47 is fixedly connected to the end of the mouth-shaped functional body 44 away from the electromagnetic stone 43, a fitting body 48 is fixedly connected to the side of the mouth-shaped functional body 44 away from the electromagnetic stone 43, and the fitting body 48 is slidingly inserted into the fitting cavity 25.

[0051] The counterweight 46 is trapezoidal, the abutting column 47 is arc surface near one end of the counterweight 46, one end of the arc surface is abutted with the inclined surface of the counterweight 46, and the middle of the fitting body 48 is provided with a through slot.

[0052] The working principle of all the above embodiments is as follows: the working process of the first assembly and the second assembly is as follows: in use, the mounting unit 13 is fixedly connected with the base 11, the screwing unit 14 is inserted into the mounting unit 13 together with the dial switch 15, the clamping body A22 and the positioning body A23 on both sides of the screwing unit 14 are clamped and aligned with the adaptive groove 21, and the screwing unit 14 is inserted into the mounting unit 13, and then the screwing unit 14 is counterclockwise screwed, in the process of screwing, the positioning body A23 gradually slides to the direction of the clamping body B26, until the wedge-shaped block at the front end of the positioning body A23 is inserted into the groove at the bottom of the clamping body B26, under the synchronous movement of the clamping body A22, the wedge-shaped end at the front end of the positioning body B27 is inserted into the arc groove on the inner surface of the clamping body A22, at this time, the surface of the positioning body A23 and the surface of the positioning body B27 are slidingly attached, when the clamping body A22 and the positioning body A23 are counterclockwise moved under the reverse screwing control of the screwing unit 14, the positioning body A23 and the clamping body B26 are clamped, the positioning body B27 and the clamping body A22 are clamped, and the screwing unit 14 and the mounting unit 13 are connected under the cooperation of the wedge-shaped blocks at the front ends of the positioning body A23 and the positioning body B27, and the two are tightly attached.

[0053] Further, when the positioning body A23 continuously deflects to the direction of the clamping body B26, the insertion slot 24 provided in the positioning body A23 continuously deflects to the column cavity 31 on the positioning body B27, when the positioning body A23 moves to the direction of the positioning body B27, the inner surface of the positioning body A23 is abutted with the inclined surface of the insertion body 33, the insertion body 33 is pushed to move into the column cavity 31, the auxiliary spring 32 is squeezed to store elastic potential energy, and when the insertion slot 24 on the positioning body A23 moves to correspond to the column cavity 31, the elastic potential energy of the auxiliary spring 32 is released, the insertion body 33 is clamped into the insertion slot 24, and this clamping prompts the operator that the screwing is in place.

[0054] Through the setting of the first assembly, the screwing of the screwing unit 14 causes the abutting body A22 and the positioning body A23 to abut and press against the abutting body B26 and the positioning body B27, respectively. In the process of assembly and disassembly, without the aid of additional tools, the dial switch 15 and the base 11 can be assembled or disassembled through simple operation, greatly improving the operation efficiency, especially suitable for scenes that need to frequently switch functions. At the same time, by using the insertion force of the positioning body A23, the positioning body B27, the abutting body A22 and the abutting body B26 in the installation process, the fitting connection between the screwing unit 14 and the mounting unit 13 is more closely connected when the installation is completed. The flat surface of the positioning body B27 and the positioning body A23 makes the sliding connection of the two flat surfaces when the screwing unit 14 is aligned with the adaptive slot 21 and installed on the base 11, which assists the stable installation and avoids the subsequent unstable falling caused by the inclination in the installation process.

[0055] Through the setting of the second assembly, the insertion slot 24 is used in cooperation with the second assembly. When the screwing unit 14 and the mounting unit 13 are installed and screwed in place, the insertion body 33 is inserted into the insertion slot 24 to provide resistance to the movement of the screwing unit 14, so as to inform the operator with a clear tactile signal. The problem of loose connection caused by insufficient screwing in the traditional structure is effectively avoided, and the deformation of the parts caused by excessive screwing is also avoided. This setting not only guarantees the reliability of the connection between the dial switch 15 and the base 11, prolongs the service life of the product, but also reduces the difficulty of subsequent disassembly and improves the operation experience of the user.

[0056] The above working process please refer to Figure 1 Figure 7 .

[0057] The working process of the third assembly is as follows: in use, the vibration generated during the driving of the automobile is transmitted to the counterweight 46. Since the counterweight 46 is connected to the positioning body B 27 through the functional spring 45, the vibration force makes the counterweight 46 move up and down, causing the counterweight 46 to press the functional spring 45. When the counterweight 46 moves up and down, since its inclined surface is connected to the abutting column 47, the up-and-down movement of the counterweight 46 causes its inclined surface to continuously abut against the abutting column 47, making the abutting column 47 move away from the electromagnet 43. The movement of the abutting column 47 causes the mouth-shaped functional body 44 to move away from the electromagnet 43 in the functional cavity 41, thereby synchronously pushing the fitting body 48 into the fitting cavity 25 and being clamped. When the automobile continues to vibrate, the counterweight 46 pushes the fitting body 48 into the fitting cavity 25. Since there are pores inside the fitting body 48, the extrusion of the fitting body 48 by the mouth-shaped functional body 44 causes the fitting body 48 to abut against the cavity wall of the fitting cavity 25 when the fitting body 48 is extruded, causing the fitting body 48 to deform. The two sides of the fitting body 48 expand outward and abut against the side wall of the fitting cavity 25, thereby enhancing the contact surface of the fitting body 48 and the fitting cavity 25, and enhancing the connection tightness between the positioning body A 23 and the positioning body B 27 through the fitting body 48.

[0058] Through the arrangement of the third assembly, when the automobile vibrates during driving, the vibration force is transmitted to the counterweight 46 to make it move up and down, and the vibration force is converted into driving force. The inclined surface of the counterweight 46 moves to trigger the movement of the mouth-shaped functional body 44, thereby controlling the connection tightness of the fitting body 48 and the fitting cavity 25. The vibration force is converted into the fastening force between the DIP switch 15 and the base 11. The energy generated by the vibration makes the connection between the DIP switch 15 and the base 11 more firm through the screwing unit 14, rather than being loose due to vibration as in the traditional structure. This feature ensures that the DIP switch 15 always maintains close contact with the base 11 during long-term use, avoiding problems such as poor circuit contact and component friction noise caused by gaps, and significantly improving the stability and reliability of the product in a vibrating environment, providing a strong guarantee for driving safety.

[0059] Through the arrangement of the whole assembly, the connection between the positioning body A 23 and the positioning body B 27 is limited from different directions by the cooperation of the plug-in body 33 and the plug-in groove 24, the engagement body 48 and the engagement cavity 25 and other components, forming multiple anti-reverse mechanisms to avoid the reverse rotation of the screwing unit 14 and the dismounting of the mounting unit 13, effectively resisting the reverse rotation force that the screwing unit 14 and the dial switch 15 may be subjected to during the driving of the automobile. Even if a certain limiting component is slightly worn or attenuated due to long-term use, other directional limiting components can still play a role, avoiding the loosening of the connection part due to reverse rotation, fundamentally eliminating the risk of dismounting, and greatly improving the reliability of the overall installation of the dial switch 15, ensuring that it always maintains a stable installation state throughout the life cycle of the automobile.
