The fixed part of angle sensor and the center pin fixed connection of automatic take-up pulley, angle sensor's rotating part and the rotating part fixed connection of automatic take-up pulley, signal prompting device and angle sensor all are connected with the electronic control unit electricity of whole car. The utility model provides an engine belt inefficacy early warning system can help the user in time to know the belt and change the demand, makes the user accomplish to change the belt in advance, avoids appearing the trouble that belt fracture or belt skidded in the driving.
Description
Technical Field
The utility model relates to the field of automotive technology, especially, relate to an engine belt inefficacy early warning system.
Background
Automobile engine generally adopts belt drive mechanism to outwards export the moment of torsion, and after working a period, wearing and tearing and lax can appear in the engine belt, and in order driving safety, the user need untimely look over whether need change the belt, if look over untimely then leave the potential safety hazard easily, consequently, how provide an automatic early warning system in order to help the user in time to know the belt and change the demand, become the technical problem that technical staff in the field had a urgent need to solve.
SUMMERY OF THE UTILITY MODEL
In view of this, the utility model provides an engine belt inefficacy early warning system, this engine belt inefficacy early warning system can help the user in time to know the belt and change the demand, makes the user accomplish to change the belt in advance, avoids appearing the trouble that belt fracture or belt skidded in the driving.
In order to achieve the above object, the utility model provides a following technical scheme:
an engine belt failure warning system comprising:
an automatic tension pulley matched with a belt of the engine;
the angle sensor is characterized in that a fixed part of the angle sensor is fixedly connected with a central shaft of the automatic tensioning wheel, a rotating part of the angle sensor is fixedly connected with a rotating part of the automatic tensioning wheel, and the angle sensor is electrically connected with an electronic control unit of the whole vehicle; and
and the signal prompter is electrically connected with the electronic control unit.
Optionally, in the above system for early warning of engine belt failure, the signal prompter is a complete vehicle instrument and/or a user mobile phone.
Optionally, in the above engine belt failure early warning system, the signal indicator is a buzzer.
Optionally, in the above-mentioned system for early warning of engine belt failure, the fixing portion of the angle sensor is connected to the central shaft of the automatic tension pulley by a nut.
According to the technical scheme, the utility model provides an among the engine belt inefficacy early warning system, with the belt matched with automatic take-up pulley of engine on install angle sensor, angle sensor's fixed part and the center pin fixed connection of automatic take-up pulley, angle sensor's rotating part and the rotating part fixed connection of automatic take-up pulley, therefore angle sensor can record automatic take-up pulley turned angle's change. Because the change of the rotation angle of the automatic tensioning wheel is in a direct proportion relation with the abrasion degree of the belt, when the rotation angle measured by the angle sensor is larger than a set value, the electronic control unit of the whole vehicle can remind a user to replace the belt by sending a signal to the signal prompter.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings required to be used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to the provided drawings without creative efforts.
Fig. 1 is an exploded view of an automatic tensioning wheel in an engine belt failure early warning system according to an embodiment of the present invention.
Labeled as:
1. a nut; 2. an angle sensor; 3. a tension wheel fixing shaft; 4. automatic tensioning wheel.
Detailed Description
For the sake of understanding, the present invention will be further described with reference to the accompanying drawings.
Referring to fig. 1, the embodiment of the utility model provides an engine belt inefficacy early warning system includes angle sensor 2, automatic take-up pulley 4 and signal prompting device (not shown in the figure), wherein, automatic take-up pulley 4 is used for cooperating with the belt of engine, when the belt is lax it is automatic taut, angle sensor 2 installs on automatic take-up pulley 4, specifically, angle sensor 2's fixed part and automatic take-up pulley 4's center pin (be take-up pulley fixed axle 3) fixed connection, angle sensor 2's rotating part and automatic take-up pulley 4's rotating part fixed connection. In addition, the angle sensor 2 and the signal prompter are electrically connected with an electronic control unit of the whole vehicle.
In this embodiment, the angle sensor 2 is connected to the tension pulley fixing shaft 3 through the nut 1, and the rotation portion of the angle sensor 2 is clamped to the automatic tension pulley 4, so that the rotation portion can rotate along with the automatic tension pulley 4. When the belt is worn and aged, the length or the thickness of the belt changes, so that the automatic tensioning wheel 4 is slightly looser than the belt with a new belt, the rotating part of the tensioning wheel fixing shaft 3 and the rotating part of the automatic tensioning wheel 4 rotate relatively, and the change of the rotation angle is in direct proportion to the wear degree of the belt.
Before using the utility model provides an engine belt inefficacy early warning system, obtain the swing angle of automatic take-up pulley 4 when the belt will break failure through experiment or calculation earlier, establish this swing angle and be an, input it into ECU (electronic control unit). When the engine belt failure early warning system is applied, the wire harness is inserted into an interface of the angle sensor 2, so that an angle value can be led into the ECU, the angle value is read after the engine is started every time, the read angle value is set to be b, the ECU compares the angle value b with a given value a, and if the angle value b is larger than or equal to the given value a, the ECU sends a signal to the signal prompter to remind a user of replacing the belt. In a specific practical application, the signal prompter can be a whole vehicle instrument, a user mobile phone or a buzzer.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to the embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
