Detailed Description
The prompt tone generating structure of the fuel lid of the present invention will be further described with reference to fig. 1 to 2.
The utility model provides a structure takes place for prompt tone of filler cap, characterized by: comprises an upper cover 1, a blocking cover 5, a positioning chuck 4, a turntable 3 and a return spring 2. The bayonet lid 5 has an accommodating groove 51 with an upper end opened. The positioning chuck 4 is in limited fit with the accommodating groove 51 of the chuck cover 5 in the circumferential direction, and the positioning chuck 4 is provided with sounding ratchets 42. The rotary table 3 is assembled on the positioning chuck 4, the sounding pawl 31 matched with the sounding ratchet 42 is formed on the side surface of the lower end of the rotary table 3, when the sounding pawl 31 slides relative to the sounding ratchet 42, a crisp prompt sound can be sent, and the linkage pawl 32 is arranged on the side wall of the upper end of the rotary table 3. The upper cover 1 is covered on the blocking cover 5 and can rotate relative to the blocking cover 5, a linkage ratchet 13 matched with the linkage pawl 32 is arranged in the upper cover 1, and the rotary table 3 is driven to synchronously rotate through the linkage ratchet 13; meanwhile, a limiting component for limiting the rotation range of the upper cover 1 is arranged between the upper cover 1 and the bayonet cover 5. The reset spring 2 is arranged between the upper cover 1 and the positioning chuck 4 or the clamping opening cover 5 to drive the rotated upper cover 1 to reset.
In actual assembly use, i.e. in an assembly structure as shown in fig. 1, the upper cover 1 cannot rotate in a clockwise direction and can rotate in a counterclockwise direction relative to the rotary table 3 through the cooperation of the interlocking pawls 32 and the interlocking ratchets 13; by the cooperation of the sounding ratchet 42 and the sounding pawl 31, the turntable 3 is rotatable in the clockwise direction and not rotatable in the counterclockwise direction with respect to the positioning chuck 4. Based on the assembly structure, when the oil tank opening is not screwed down, the upper cover 1 can drive the clamping opening cover 5 to synchronously rotate; after the clamping opening cover 5 is screwed to a certain angle on the oil tank opening, namely after the clamping opening cover 5 is screwed to a certain position, the clamping opening cover 5 does not synchronously rotate along with the upper cover 1, the upper cover 1 drives the rotary table 3 to rotate in the clockwise direction relative to the positioning chuck 4, the sounding pawl 31 slides on the sounding ratchet 42, when the sounding pawl 31 slides from the current sounding ratchet 42 to the next sounding ratchet 42, the sounding pawl 31 jumps, collides with the next sounding ratchet 42, and simultaneously gives out collision sound, wherein the collision sound is prompt sound, and the sound is clear and crisp; meanwhile, the upper cover 1 cannot rotate clockwise due to the limitation of the limiting component. The upper cover 1 is loosened, the reset spring 2 drives the tooth position of the upper cover 1 to rotate by one linkage ratchet 13, namely the upper cover 1 is reset to the starting position, under the condition, the upper cover 1 can drive the linkage pawl 32 to jump, so that the prompt tone is sent again, the prompt tone can be sent out circularly, and the problem that an operator misses the prompt tone is avoided.
In order to promote the volume of the prompt tone, the shaping of the sounding pawl 31 has a plurality of, 4 in this embodiment, under this structure, when rotating the carousel 3, four sounding pawls 31 can collide the sounding ratchet 42 that corresponds simultaneously to the simultaneous sound production has been showing and has been promoting the volume that the prompt tone sent.
Specifically, a positioning rib 52 extending in the axial direction of the bayonet cap 5 is formed on the inner wall of the receiving groove 51 of the bayonet cap 5, and a positioning groove 44 engaged with the positioning rib 52 is formed on the side surface of the positioning collet 4. The positioning clip 4 can be restricted from rotating in the clip cover 5 by the cooperation of the positioning rib 52 and the positioning groove 44.
The upper surface of the positioning chuck 4 is provided with a circular groove 41 for the turntable 3 to be arranged in, and the sounding ratchets are positioned on the circumferential inner wall of the circular groove 41. The setting of circular slot 41 can promote the stability of carousel 3 assembly on location chuck 4 to promote the stability of whole filler cap sound production.
The thickness of the sounding pawl 31 is larger than that of the interlocking pawl 32. In a certain thickness range, when the thickness of the sounding pawl 31 is thicker, the potential energy thereof at the time of deformation is larger, and therefore, the impact force to the sounding ratchet 42 is larger, and the sound volume of the generated warning sound is larger.
The inner part of the upper cover 1 is provided with a sleeve 12, the linkage ratchet 13 is positioned on the inner wall of the sleeve 12, the linkage pawl 32 is positioned outside the circular groove 41 and enters the sleeve 12 to be matched with the linkage pawl 32.
Have last registration arm 14 and lower registration arm 43 on upper cover 1 and location chuck 4 respectively, all have location opening 141, 431 on the lateral wall of last registration arm 14 and lower registration arm 43, reset spring 2 is the torsional spring, the spacing cooperation of upper end and last registration arm 14 circumference of torsional spring, the spacing cooperation of lower extreme and lower registration arm 43 circumference of torsional spring. Specifically, the upper end of the torsion spring is positioned in the upper positioning tube 14, and the head 21 at the upper end of the torsion spring is clamped in the positioning opening 141 on the upper positioning tube 14; the lower end of the torsion spring is positioned within the lower positioning tube 43, while the head 22 of the lower end of the torsion spring is engaged within the positioning opening 431 of the lower positioning tube 43. Therefore, when the upper cover 1 rotates relative to the positioning chuck 4, the torsion spring is twisted and deformed, and when the force on the upper cover 1 is removed, the torsion spring can drive the linkage ratchet 13 in the upper cover to slide on the linkage pawl 32, so that the rotary reset is realized.
The limiting assembly comprises an upper limiting block 11 positioned on the inner wall of the upper cover 1 and two lower limiting blocks 53 positioned on the outer wall of the clamping cover 5, wherein the upper limiting block 11 is positioned between the two lower limiting blocks 53, so that the upper cover 1 is in a rotating range relative to the clamping cover 5, namely, the distance between the two lower limiting blocks 53. Specifically, the rotation range of the upper cover 1 relative to the blocking cover 5 is as follows: the sounding pawl 31 slides from the current sounding ratchet 42 to the next sounding ratchet 42 adjacent to the current sounding ratchet 42.
