Description

Technical Field

[0001] This utility model relates to the field of automotive cab mounting, specifically a novel hydraulic lock micro switch. Background Technology

[0002] As a key component of the cab suspension system, the hydraulic lock controls the locking and unlocking of the cab by opening and closing, ensuring safety during vehicle operation and cab rollover. The opening and closing status of the hydraulic lock needs to be monitored by a microswitch and fed back to the alarm device in real time; therefore, the role of the microswitch is self-evident. However, traditional hydraulic lock microswitches suffer from problems such as single-stage working stroke, poor versatility, complex disassembly and reassembly due to threaded connection to the alarm device wiring harness, and short service life. Utility Model Content

[0003] In order to solve the above problems, the purpose of this utility model is to provide a new type of hydraulic lock micro switch.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: A novel hydraulic lock micro switch includes a switch connector sleeve and a fixed connector. The main structure of the switch connector sleeve and the fixed connector is cylindrical, and the trigger end of the switch connector sleeve is inserted into one end of the fixed connector, forming a cylindrical cavity structure after the switch connector sleeve and the fixed connector are inserted. A double contact structure is fixedly inserted through the central sealing structure of the switch connector sleeve. The outer end of the double contact structure is used to connect to the wiring harness of the alarm device, and the inner trigger end of the double contact structure is located inside the cavity structure. A plastic gasket and an elastic gasket are provided inside between the switch connector sleeve and the fixed connector. There is space for the elastic gasket to move between the plastic gasket and the pressing gasket. The elastic gasket divides the cavity structure into two parts, wherein the cavity structure on one side of the double contact structure is... The secondary structure includes a rebound spring, a double-contact washer, and a contact pad. The center contact of the double-contact washer is directly opposite the trigger end of the double-contact structure. The spring force of the rebound spring moves the double-contact washer away from the double-contact structure. The pressing post of the contact pad penetrates the center opening of the plastic washer and contacts the center of the elastic washer. An outer metal contact that penetrates the fixed joint is provided on the other side of the cavity structure. The outer end of the outer metal contact extends to the outside of the fixed joint, and the inner end of the outer metal contact is located in the cavity structure and is fitted with a retractable cylindrical inner metal contact. The other end of the inner metal contact is sealed, and its outer side is separated from the pressing washer and opposite to it. A buffer spring is provided inside the inner metal contact. The other end of the buffer spring is located inside the outer metal contact. The buffer spring keeps the telescopic structure formed by the inner metal contact and the outer metal contact in an extended state. The other end of the fixed joint is fixed to the hydraulic lock by external threads.

[0005] Furthermore, the inner side of the switch connector sheath is provided with opposing motion guide grooves, and the two ends of the double contact pad and the contact pad are respectively provided with guide protrusions located in the motion guide grooves.

[0006] Furthermore, there are two spring springs in total. The inner side of the switch connector sheath on the upper and lower parts of the double contact structure is provided with spring positioning grooves, and one end of the spring spring is located in the corresponding spring positioning groove.

[0007] Furthermore, one side of the contact pad is provided with a positioning post that penetrates the double contact pad, and the other end of the rebound spring is respectively fitted onto the positioning post.

[0008] Furthermore, the elastic gasket is made of rubber material.

[0009] Furthermore, the outer wall of the switch connector sheath at the connection point between the switch connector sheath and the alarm device wiring harness is provided with a plug-in sleeve for insertion, and the inner wall of the outer end of the plug-in sleeve is provided with a barb structure.

[0010] Furthermore, the first stroke occurs when the rebound spring is compressed and the double-contact gasket contacts the double contacts of the switch connector sheath; the second stroke occurs when the buffer spring is compressed and the telescopic structure formed by the inner and outer metal contacts contracts.

[0011] Through the above settings, this utility model optimizes the structural design of the hydraulic lock micro switch, increasing the working stroke of the micro switch. The secondary stroke can effectively buffer and release force, effectively solving the problem of damage to the internal double contacts of the micro switch due to excessive contact force, and significantly improving the product's service life. At the same time, due to the increased stroke of the micro switch, the types of micro switches are reduced, and the application range is wider. In addition, the connection method between the micro switch and the alarm device wiring harness is optimized from a threaded connection to a plug-in structure, which can effectively achieve quick connection and convenient disassembly.

[0015] Fig. 3 This is a schematic diagram of the structure of this utility model in use. Detailed Implementation

[0016] like Figs. 1-3As shown, a novel hydraulic lock micro switch includes a switch connector sleeve 1 and a fixed connector 10. The main structure of the switch connector sleeve 1 and the fixed connector 10 is cylindrical, with one trigger end of the switch connector sleeve 1 inserted into one end of the fixed connector 10, forming a cylindrical cavity structure after insertion. A double-contact structure 11 is fixedly fixed through the central sealing structure of the switch connector sleeve 1. The outer end of the double-contact structure 11 is used to connect to the alarm device wiring harness, and the inner trigger end of the double-contact structure 11 is located within the cavity structure. A plastic gasket 5 and an elastic gasket 6 are internally arranged between the switch connector sleeve 1 and the fixed connector 10. If the elastic gasket 6 is made of rubber, it can effectively seal and buffer, preventing water and dust from entering the interior and improving service life. Space is left between the plastic gasket 5 and the pressing gasket 6 for the elastic gasket 6 to move. The elastic gasket 6 divides the cavity structure into two parts, where the double-contact... Inside the cavity structure on one side of the point structure 11, a spring 2, a double contact pad 3, and a contact pad 4 are arranged in sequence. The center contact of the double contact pad 3 is directly opposite the trigger end of the double contact structure 11. The spring force of the spring 2 makes the double contact pad 3 move away from the double contact structure 11. The pressing post of the contact pad 4 passes through the center opening of the plastic pad 5 and contacts the center of the elastic pad 6. On the other side of the cavity structure, an outer metal contact 9 that passes through the fixed connector 10 is arranged. The outer end of the outer metal contact 9 extends to the outside of the fixed connector 10. The inner end of the outer metal contact 9 is located inside the cavity structure and is fitted with a telescopic cylindrical inner metal contact 7. The other end of the inner metal contact 7 is sealed and its outer side is separated from the pressing pad 6. A buffer spring 8 is arranged inside the inner metal contact 7. The other end of the buffer spring 8 is located inside the outer metal contact 9. The buffer spring 8 keeps the telescopic structure formed by the inner metal contact 7 and the outer metal contact 9 in an extended state. The other end of the fixed connector 10 is fixed to the hydraulic lock by external thread.

[0017] The inner side of the switch connector sleeve 1 is provided with opposing motion guide grooves 12. The two ends of the double contact pad 3 and the contact pad 4 are respectively provided with guide protrusions 13 located in the motion guide grooves 12. There are two spring springs 2 in total. The inner side of the switch connector sleeve 1 above and below the double contact structure 11 is respectively provided with spring positioning grooves 14. One end of the spring spring 2 is located in the corresponding spring positioning groove 14. One side of the contact pad 4 is provided with a positioning post 15 that penetrates the double contact pad 3. The other end of the spring spring 2 is respectively sleeved on the positioning post 15, which effectively ensures that the spring spring 2 does not tilt after assembly.

[0018] The outer wall of the switch connector sleeve 1 at the connection point between the switch connector sleeve 1 and the alarm device wiring harness is provided with a plug-in sleeve 16 for plugging in. The inner wall of the outer end of the plug-in sleeve 16 is provided with a barb structure 17, which can effectively achieve quick connection and convenient disassembly.

[0019] When the spring 2 is compressed and the double-contact pad 3 is in contact with the double contacts of the switch connector sleeve 1, it is the first stroke. After being compressed, the spring 2 can provide sufficient resistance and rebound force. The resistance can effectively prevent false alarms, and the rebound force can promptly return to its original position and separate the contacts. When the buffer spring 8 is compressed and the telescopic structure formed by the inner metal contact 7 and the outer metal contact 9 is contracted, it is the second stroke. The second stroke opens after the first stroke reaches its limit, effectively preventing damage from the rigid contact between the double-contact pad 3 and the double contacts of the switch connector sleeve 1, thus improving service life. At the same time, due to the increased stroke of the micro switch, the types of micro switches are reduced, and the application range is wider.

[0020] The above description is merely an illustrative embodiment of this utility model and is not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model.
