The integrated cylinder cover is characterized in that the cylinder cover seat is arranged on the cylinder cover seat, the cylinder cover seat is connected with the cylinder wire harness, and the cylinder cover seat is connected with the cylinder cover.
Description
Technical Field
The utility model belongs to a cylinder head cover structure of an engine, and particularly relates to a structure for mounting a wire harness in a cylinder on the cylinder head cover of the engine.
Background
At present, oil injectors of a four-valve diesel engine are arranged in a cylinder cover, a cylinder cover is generally arranged outside an engine cylinder cover, a sensor is arranged on an oil injector wire harness, and signals of the sensors are required to be transmitted through the wire harness. The wire harnesses connecting the sensors are typically connected by a head cover to an external wire harness, and these wire harnesses located inside the head cover are referred to as in-cylinder wire harnesses. The in-cylinder wire harness is fixed on the cylinder cover through a wire harness bracket, and the most common mode for connecting the in-cylinder wire harness and the engine wire harness at present is through a seat fixed connection arranged in the middle of a cylinder cover. The cylinder head cover seat is a layer of housing which is added between the cylinder head and the cylinder head cover, and the connection mode of the wire harness in the cylinder and the engine wire harness is used for assembling more parts, so that the assembly structure is complex, the assembly process is complex, and the improvement of the assembly efficiency is not facilitated. In addition, the cylinder cover connecting seat and the cylinder cover are sealed by the adhesive tape, so that the oil leakage probability of the engine is increased, and the whole engine assembly efficiency is caused.
Disclosure of Invention
The utility model aims to provide an engine cylinder cover with an in-cylinder wire harness outlet, which is an integrated cylinder cover and eliminates the traditional cylinder cover seat structure.
The utility model adopts the following technical scheme: the engine cylinder cover with the in-cylinder wire harness outlet is structurally characterized in that the wire harness outlet is arranged on the side wall of the cylinder cover, and the in-cylinder wire harnesses of each cylinder of the engine are concentrated together and led to the wire harness outlet. The side of the cylinder cover is provided with a clamp spring groove and a clamp spring sheet, the clamp spring sheet fixes the wire harness in the cylinder on the inner wall of the cylinder cover, and a limit bolt is arranged above the wire harness in the cylinder to prevent the clamp spring sheet from falling out of the clamp spring groove. The wire harness in the cylinder extends to a wire harness outlet on the side wall of the cylinder cover from the snap spring, and a sealing ring is arranged at the position of the wire harness outlet of the cylinder cover to prevent oil leakage of the cylinder cover.
Compared with the prior art, the structure of the cylinder head cover is innovative in that: the in-cylinder wire harness is directly installed on the cylinder cover, and the in-cylinder wire harness is connected with the external wire harness in a mode of not adopting the cylinder cover connecting seat, so that the space occupied by the cylinder cover connecting seat is saved, and the installation space of the engine is saved.
Drawings
Fig. 1 is a schematic and external view of the present utility model.
Fig. 2 is a sectional structural view of the wire harness outlet position of the present utility model.
Fig. 3 is a view of the structure of fig. 1 in the bottom view.
Fig. 4 is a partial structural view of the fixed in-cylinder harness.
The utility model has the characteristics and beneficial effects that: the structure is an integrated cylinder cover, is easy to process, and does not need to additionally increase a cylinder cover seat to connect the wire harness in the cylinder, so that the wire harness cylinder penetrating through the cylinder cover seat is avoided. The structure is arranged at the wire harness outlet on the cylinder cover in an interference manner through the sealing rubber strip arranged on the wire harness in the cylinder, so that the rubber strip between the cylinder cover seat and the cylinder cover is omitted, oil leakage points of the engine are reduced, and the assembly efficiency of the whole engine is improved.
Detailed Description
The structural principles of the present utility model will be further described below with reference to the drawings and by the detailed description.
The engine cylinder cover with the in-cylinder wire harness outlet has the specific structure that: a wire harness outlet 1-1 is provided at a side of the head cover 1 for connecting an in-cylinder wire harness and an engine wire harness, and the in-cylinder wire harness 2 of the engine is led together to the wire harness outlet (see fig. 3). The side face of the cylinder cover is provided with a clamp spring groove 2-2 and a clamp spring sheet 4, and the wire bundle in the cylinder is fixed at the wire bundle outlet through the clamp spring sheet. Specifically, a clamping spring groove is formed in the connecting and inserting end of the front portion of the wire harness in the cylinder, the clamping spring groove at the front end of the wire harness is exposed out of the wire harness outlet, then a clamping spring sheet is inserted into the clamping spring groove, and a limit bolt 3 is arranged above the outer portion of the wire harness in the cylinder (as shown in fig. 1 and 2). The setting of the limit bolt is mainly because the engine is provided with a certain inclination angle, and the engine frequently shakes when the automobile works in different environments. One end of the clamping spring is inserted into the clamping spring groove, if the clamping spring possibly comes out of the groove due to vibration, the limiting bolt can be used for 'propping' the clamping spring once the clamping spring is separated (as shown in fig. 4), and oil leakage faults of the engine are caused by the separation of the clamping spring. The wire harness in the cylinder extends to the wire harness outlet of the side wall of the cylinder cover from the snap spring, a sealing ring 5 is arranged at the position of the wire harness outlet of the cylinder cover, and the sealing ring is aimed at sealing oil gas in the cylinder cover and preventing oil leakage.
The clamping reed is arranged in a clamping spring groove above the wire harness in the cylinder cover cylinder. The sealing ring is arranged between the cylinder cover and the in-cylinder wire bundle.
The engine used in the present embodiment is a diesel engine. The wire harness outlet is arranged on the side face of the cylinder cover so as to facilitate connection and installation of the wire harness in the cylinder. After the wire harness in the cylinder of the engine passes through each cylinder, the wire harness is arranged in the cylinder head cover according to a set path and is concentrated to a wire harness outlet of the cylinder head cover (shown in fig. 1 and 2). The sealing ring is used for sealing a gap possibly existing between the cylinder cover and the wire bundle in the cylinder so as to prevent lubricating oil from leaking. And a limit bolt is arranged above the wire harness in the cylinder to prevent the wire harness snap spring from falling off.
