Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The piston type intelligent oil filling cover is arranged at the opening of an oil filling pipe of an automobile oil tank and is in matched sealing connection with the oil filling pipe through threads. Including upper cover, lid body, drive mechanism, actuating mechanism and resetting means, wherein the upper cover surrounds with the lid body and forms the transmission chamber, places the transmission intracavity in the drive mechanism and connects upper cover and lid body, and lid body lateral wall is provided with the screw thread, with the screw-thread fit sealing connection on the inner wall of oil filler pipe mouth of pipe department. When installing this oil filling lid on adding oil pipe, the lid body inserts in adding oil pipe, and the upper cover stays outside of the oil pipe, when needs open the oil tank (like when adding oil), through rotating the upper cover that exposes outside adding oil pipe, then drives the lid body rotation in adding oil pipe through drive mechanism to twist off and add oil cover. In order to meet the sealing performance between the oil filling cover and the oil filling pipe, the radius of the upper cover is larger than that of the cover body, a circle of groove is formed between the upper cover and the cover body, and a sealing gasket is arranged in the groove. When this oil filling cover is installed on adding oil pipe, add the mouth of pipe of oil pipe and insert the recess in, compress tightly sealed pad, fill up the clearance that adds between oil pipe and the upper cover recess through sealed pad and realize sealedly.
When oil tank internal pressure is big to a certain extent, actuating mechanism can drive mechanism and remove and with upper cover or lid body separation under the effect of pressure, destroys being connected between upper cover and the lid body for the rotation of upper cover can't transmit the lid on one's body through drive mechanism. When the internal pressure of the oil tank is high to a certain degree, the oil filling cover cannot be screwed down by rotating the upper cover, so that the occurrence of accidents of hurting people is avoided.
The reset device is connected with the transmission mechanism, and the restoring force direction of the reset device is opposite to the driving direction of the driving mechanism. When the internal pressure of the oil tank is reduced to a normal value again, the resetting device can drive the transmission mechanism to move reversely, and the connection between the upper cover and the cover body is restored, so that the rotation of the upper cover can be transmitted to the cover body through the transmission mechanism, namely, the oil filling cover is smoothly screwed off by rotating the upper cover.
In the first embodiment, please refer to fig. 1.
In the present embodiment, the driving mechanism 5c is mechanically driven to separate the transmission mechanism from the cover body according to the pressure in the oil tank, and specifically includes an upper cover 1c, a cover body 2c, a transmission mechanism 3c, a gasket 4c, a driving mechanism 5c, and a reset device 6 c.
Tooth grooves are formed in the inner wall of the upper cover 1c along the axis direction, and the tooth grooves are also formed in the inner wall of the cover body 2c along the axis direction. Upper cover 1c, cover body 2c and the coaxial arrangement of drive mechanism 3c three, drive mechanism 3c outwards extends first connecting portion and second connecting portion along its radial direction, first connecting portion offer with upper cover 1 c's tooth's socket matched with be connected the tooth, the second connecting portion offer with cover body 2 c's tooth's socket matched with be connected the tooth, through the cooperation of connecting tooth and tooth's socket, the rotation of upper cover 1c self can transmit for cover body 2c through drive mechanism 3c, it is rotatory to drive cover body 2 c.
The connection mode of the transmission mechanism 3c and the upper cover 1c and the cover body 2c can also adopt transition fit connection relation, and the rotation of the upper cover 1c is transmitted to the cover body 2c by means of the friction force on the contact surface between the transmission mechanism 3c and the upper cover 1c and the cover body 2 c. Compared with the above-mentioned manner of engaging and connecting the tooth socket and the connecting tooth, the manner of engaging and connecting the tooth socket and the connecting tooth is inferior in reliability and durability, and in practical use, the manner of engaging and connecting the tooth socket and the connecting tooth is preferable.
A circle of groove is formed between the upper cover 1c and the cover body 2c, and a sealing gasket 4c is arranged in the groove. This oil filler cap is used for sealing this gap of filling oil between lid and the oil pipe when installing on filling oil pipe.
The cover body 2c is provided with a pipeline part which is a cylindrical cavity and is provided with a through hole 21c communicated with the pipeline part, the driving mechanism 5c comprises a piston 51c and a sealing ring 52c, and the piston 51c is arranged in the cover body 2c and forms a gap with the inner wall of the cover body 2 c. The seal ring 52c is fitted over the piston 51c to seal a gap between the piston 51c and the inner wall of the cover body 2c, and the piston 51c is slidable in the axial direction of the pipe portion. The lower end of the transmission mechanism 3c is connected to the piston 51c in a general abutting manner, or in an integrally formed manner by using a connecting member such as a bolt or a clip.
When the pressure inside the tank rises, the pressure pushes the piston 51c to move towards the inside of the cap body 2c, and the seal ring 52c also moves along with the piston 51c, maintaining airtightness throughout the movement. The driving mechanism 3c is pushed to move towards the upper cover 1c until the connecting teeth of the second connecting part are separated from the tooth grooves of the cover body 2 c. The connection between drive mechanism 3c and the lid body 2c is destroyed, and the rotation of upper cover 1c can't transmit to lid body 2c through drive mechanism 3c on, when oil tank internal pressure was too big promptly, can't take off this oil filler lid through rotating upper cover 1c, has realized the protection to personnel.
The return means 6c is a spring in the present embodiment, and other elastic member or a driving mechanism such as a motor may be used, and is provided in the upper cover 1c, and has one end abutting against the upper cover 1c and the other end abutting against the first connecting portion 31c, and is arranged coaxially with the piston 51 c. When the gas pressure in the tank returns to normal, the pressure applied to the piston 51c decreases, and the elastic force of the resetting device 6c is larger than the pressure applied to the piston 51c by the gas in the tank. The transmission mechanism 3c moves towards the piston 51c, the connecting teeth of the second connecting part are re-engaged with the tooth grooves of the cover body 2c, the connection between the transmission mechanism 3c and the cover body 2c is restored, the rotation of the upper cover 1c can be transmitted to the cover body 2c through the transmission mechanism 3c, and the oil filling cover can be taken down by screwing the upper cover 1 c.
Implement the embodiment of the utility model provides a, following beneficial effect has: the utility model discloses an upper cover of piston intelligence adds oil cap is connected through drive mechanism and lid body, and when oil tank internal pressure was too big, the piston can promote drive mechanism inward movement for drive mechanism and lid body separation, when rotating the upper cover and trying to take off this and adding oil cap, the rotation of upper cover can't transmit to the lid on one's body, makes this add oil cap can't take off, has avoided the emergence of hindering the people accident.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
