Description

Vehicle driving lever state detection assembly and vehicle

Technical Field

The utility model belongs to the field of driving assistance systems, and particularly relates to a technology for detecting a state of a driving lever on a vehicle.

Background

The joystick (i.e., the lever) under the steering wheel of a vehicle has a variety of functions, typically two of: one is a vehicle lamp lever and the other is a vehicle wiper lever.

The lamp-off control rod can control the turning-on and turning-off of corresponding steering lamps, dipped headlights, high beam lamps and fog lamps on the vehicle according to different toggle states; the windshield wiper control rod can control the opening and closing of the vehicle windshield wiper function and the used vehicle glass water; and a steering column switch module in the vehicle forms a control signal, such as a left or right turn signal or a wiper speed control signal, by effectively detecting the position of the lever.

In order to accurately detect the toggle position of the toggle lever, many mature solutions exist, wherein a detection scheme based on the cooperation of a magnet and a hall sensor is one of the solutions. The principle of the scheme is based on magnetic vectors of different angles formed in a magnetic field around the magnet, and the Hall sensor can effectively read the angles of the magnetic vectors, so that when the magnet is moved nearby the Hall sensor, the Hall sensor can recognize the magnetic vectors of different angles. On the basis, only the correct magnetic angle is added to each deflector rod position, and each lever position can be accurately identified through the Hall sensor.

In practical application, a main PCB in the steering column switch module is used for acquiring and processing signals generated by the Hall sensor. Because the magnetic field generated by the magnet is not characterized in that the area around the magnet meets the detection requirement, in order to ensure the reliability of the cooperation between the Hall sensor and the magnet, the Hall sensor and the magnet are required to be correspondingly placed in a specific space area; meanwhile, the absolute linearity of the space inside the steering column is considered, so that great difficulty is brought to the connection arrangement between the Hall sensor and the main PCB in the steering column switch module.

Referring to fig. 1, a first arrangement of a hall sensor and a magnet in a steering column switch module in a prior art arrangement is shown.

In the scheme, the Hall sensor 5 is directly arranged on the main PCB 3 in the steering column switch module 2, and is matched with the main PCB, so that the magnet 4 is correspondingly arranged at the action end of the deflector rod 1 in the steering column switch module 2.

In practical application, the size of the main PCB 3 is required to be larger so as to meet the functional requirement in order to arrange the Hall sensor 5 in the movement range of the magnet 4 due to the limitation of the movement range of the deflector rod 1; when the large-sized main PCB 3 is disposed in the steering column switch module 2, a larger space is required for disposing, so that the volume of the steering column switch module 2 needs to be increased. Therefore, the volume and the weight of the steering column switch module 2 are increased, the actual application requirements cannot be met, and the cost is greatly increased.

Referring to fig. 2, a second arrangement of hall sensors and magnets in a steering column switch module is shown in the prior art.

In the scheme, a Hall sensor 5 is independently arranged in a steering column switch module 2 and is connected to a main PCB 3 in the steering column switch module 2 through a connecting component 6; in cooperation with this, the magnet 4 is correspondingly arranged on the actuating end of the shift lever 1 in the steering column switch module 2.

According to the arrangement scheme, an additional connecting component is required to be additionally arranged, if an independent connecting wire harness is required to be adopted, and meanwhile, a corresponding connector or a connecting interface is additionally arranged on the main PCB 3, so that the cost is greatly increased; meanwhile, an interface connected with the Hall sensor is required to be arranged on the main PCB, so that the size and the structure of the main PCB are increased, and a larger installation space is required to be occupied when the main PCB is deployed.

Detailed Description

The utility model is further described with reference to the following detailed drawings in order to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the implementation of the utility model easy to understand.

Aiming at the increasing number of functions integrated on the deflector rod, how to reliably and accurately detect the deflector rod poking position in the limited space inside the steering column switch module is particularly important;

furthermore, when the position detection is realized based on the cooperation between the magnet and the Hall sensor, the relative positions of the magnet and the Hall sensor are required to meet the requirement of the sensor on magnetic field sensing;

moreover, the rotation positions of the deflector rods are preset according to different functions, so that when the magnet and the Hall sensor are arranged in the steering column switch module, the arrangement positions of the magnet are required to be indirectly fixed in a certain range.

Based on the simultaneous limitation of the three conditions, the technical limitation is greatly brought to the arrangement of the magnet and the Hall sensor in the steering column switch module.

Under the condition, the utility model forms a corresponding vehicle driving lever state detection assembly based on the cooperation of the Hall sensor and the magnet, simultaneously innovatively and directly integrates the Hall sensor on a flexible circuit board which is used for connecting the upper function of the driving lever on the driving lever and a main PCB (printed circuit board) in the steering column switch module in the vehicle driving lever, and based on the flexibility and extensibility of the flexible circuit board, the Hall sensor is distributed in an effective magnetic field area of the magnet along with the flexible circuit board, and meanwhile, the magnetic Hall sensor arranged on the flexible circuit board in the vehicle driving lever and the magnet can perform relative motion according to the stirring of the driving lever, thereby realizing induction cooperation to finish the detection of the position state of the vehicle driving lever, breaking through the double limitation of the inner space and the assembly cost of the steering column switch module and achieving a very high application effect.

When the Hall sensor is directly integrated and arranged in the vehicle deflector rod and used for connecting the function on the deflector rod with the flexible circuit board of the main PCB in the steering column switch module, the Hall sensor is preferably welded on the flexible circuit board through a surface mounting process, so that the stable arrangement of the Hall sensor on the flexible circuit board is ensured.

For example, when the Hall sensor is arranged on the flexible circuit board, the functional pins on the Hall sensor are directly connected and conducted with the extended circuits on the flexible circuit board, so that the sensing signals generated by the Hall sensor can be directly transmitted to the main PCB board through the flexible circuit board, and meanwhile, the normal signal transmission of other functional circuits in the flexible circuit board is not influenced.

In some embodiments of the present utility model, when the present vehicle lever state detection assembly is deployed in a steering column switch module, a hall sensor integrated on a flexible circuit board in the lever may be deployed as a fixed component, while a mating magnet is deployed as a moving component.

Referring to fig. 3, an exemplary diagram of a vehicle lever state detection assembly having the hall sensor 10 as a stationary component and the magnet 20 as a moving component is shown deployed in a steering column switch module 50.

In this example, the hall sensor 10 is integrally provided directly on a flexible circuit board 40 in the vehicle lever 30 for connecting the functions on the lever with the main PCB board in the steering column switch module.

The flexible circuit board 40 is disposed in the vehicle shift lever 30, and is used for connecting the corresponding shift lever upper function 31 on the vehicle shift lever 30, integrally extending from the vehicle shift lever 30 to the steering column switch module 50, and electrically connecting with the main PCB board 60 in the steering column switch module, so as to transmit the control signal generated by driving the corresponding shift lever upper function 31 on the vehicle shift lever 30 to the main PCB board 60 in the steering column switch module.

At the same time, the hall sensor 10 integrally provided on the flexible circuit board 40 will also directly transfer the generated sensing signal based on the flexible circuit board 40 to the main PCB board 60 in the steering column switch module.

Further, the hall sensor 10 is integrally disposed on the extension of the flexible circuit board 40 in the steering column switch module 50, and the extension of the flexible circuit board 40 in the steering column switch module 50 has a sufficient length and a sufficient deformation margin to enable the hall sensor 10 to be fixedly disposed in the steering column switch module 50. The hall sensors 10 thus arranged are arranged in a fixed manner in the steering column switch module 50 relative to the driver 30

In cooperation with this, the magnet 20 is directly disposed on the swing portion of the vehicle lever 30 located in the steering column switch module 50, and is a moving member with respect to the hall sensor 10, and can move relatively with respect to the hall sensor 10 fixedly disposed along with the lever 30.

Here, the arrangement of the magnets 20 and the hall sensors 10 needs to be such that the sensing area of the hall sensors 10 can be located within the effective magnetic field area generated by the magnets 20.

By way of further illustration, referring to fig. 4, there is shown one example of an application of the vehicle lever state detection assembly with the hall sensor 10 as a stationary component and the magnet 20 as a moving component deployed in the steering column switch module 50.

As shown in the drawing, when the vehicle lever state detection assembly using the magnet 20 as a moving part is deployed and assembled, the magnet 20 as a moving part is fixedly disposed on a swinging portion of the vehicle lever 30 extending into the steering column switch module 50 through the corresponding magnet fixing bracket 21.

In order to facilitate the distribution of the hall sensors 10 integrated on the flexible circuit board 40 in the driving lever and ensure the reliability of the cooperation of the two, the magnets 20 are preferably distributed in a certain inclination mode, so that the hall sensors 10 are given a larger deployment degree of freedom, and meanwhile, the magnets 20 can be always in the sensing range of the hall sensors 10 and the sensing sensitivity can be ensured when the magnets 20 move along with the driving lever 30 of the vehicle relative to the hall sensors 10.

In addition, since the vehicle shift lever 30 needs to be shifted, in order to ensure the stability of the combination between the magnet 20 and the vehicle shift lever 30, the vehicle shift lever 30 is provided with a corresponding magnet fixing bracket 21 facing the deployment position of the magnet 20 on the swinging portion inside the steering column switch module 50, and the magnet fixing bracket 21 may be integrally formed on the vehicle shift lever 30 or may be mounted on the vehicle shift lever 30 by a separate component.

The specific structure of the magnet fixing bracket 21 can be determined according to practical requirements to match the deployment of the magnet 20. On this basis, the magnet 20 is fixedly arranged on the magnet fixing bracket 21, and a specific fixing structure can be an assembled fixing structure such as a buckle or riveting structure, or an insert injection fixing structure.

A flexible circuit board 40 in the shift lever 30 has one end electrically connected to the shift lever upper function 31 on the shift lever 30 and the other end extending from within the shift lever 30 to within the steering column switch module 50 and electrically connected to the main PCB board 60 in the steering column switch module 50 via a corresponding connector 44.

On this basis, the hall sensor 10 is integrally disposed on the extension portion of the flexible circuit board 40 located in the steering column switch module 50, and the specific location of the integrated disposition may be determined according to practical requirements, so that the extension portion of the flexible circuit board 40 located in the steering column switch module 50 is the first extension portion 41, the integrated portion 42 and the second extension portion 43.

The integration portion 42 here is for integrally disposing the hall sensor 10; the first extension portion 41 is distributed between the shift lever 30 and the integrated portion 42, and is used as a deformable portion to support the shift lever 30 for movement in the steering column switch module 50, i.e. to correspondingly deform along with the movement of the shift lever 30 in the steering column switch module 50; the second extension 43 is then distributed between the integration 42 and the connector 44 as an extension transmission and can adapt the internal structural form of the steering column switch module 50 on the basis of its own flexible deformation.

The hall sensor 10 is fixedly disposed on a corresponding fixing bracket 11 together with an integrated portion 42 on the flexible circuit board 40, the fixing bracket 11 is fixedly disposed in the steering column switch module 50, and the hall sensor 10 disposed thereon can be distributed with respect to the magnet 20 on the deflector rod 30 such that the hall sensor 10 is located in an effective magnetic field generated by the magnet 20.

For example, the specific structural form of the fixing bracket 11 may be determined according to practical requirements, so as to match with the deployment setting of the hall sensor 10 relative to the magnet 20; if the fixing bracket 11 is formed with a mounting surface facing the magnet 20, the hall sensor 10 and the integrated part 42 on the flexible circuit board 40 can be fixed on the mounting surface on the fixing bracket 11 by bonding or embedding, so that the hall sensor 10 is fixedly distributed relative to the magnet 20.

As a further supplementary example, referring to fig. 5, the extension portion (including the first extension portion 41, the integrated portion 42 and the second extension portion 43) of the flexible circuit board 40 located in the steering column switch module 50 is preferably distributed below the mating structure of the shifter lever 30 and the steering column switch module 50, so that a larger mating structure space and a larger degree of freedom of the mating between the shifter lever 30 and the steering column switch module 50 can be provided; at the same time, the shifting lever 30 can be prevented from being shifted relative to the steering column switch module 50, and the influence on the flexible circuit board 40 can be avoided.

As shown in fig. 5, when the flexible circuit board 40 is distributed and arranged, the flexible circuit board is integrally distributed below the matching structure of the shift lever 30 and the steering column switch module 50 when extending into the steering column switch module 50 along the shift lever 30, wherein the first extension portion 41 extends and distributes in a certain bending state, so that the first extension portion 41 can have a larger expansion adjustment allowance to adapt to the actual adjustment of the mounting structure;

on the basis, the position of the first extension part 41, which is matched with the placement surface on the fixed support 11, is used as an integrated part 42, and a circuit for connecting the Hall sensor 10 is expanded in the integrated part 42 and is used for integrally arranging the Hall sensor 10;

on the basis, the second extending part 43 is formed by extending outwards from the side edge of the integrated part 42, the second extending part 43 extends to the side surface of the matching structure of the deflector rod 30 and the steering column switch module 50 through the bending structure, so that the relative action matching area between the deflector rod 30 and the steering column switch module 50 is effectively avoided, the influence of the stirring of the deflector rod 30 on the flexible circuit board is avoided, and the stability and the reliability of the connection setting of the flexible circuit board 40 are ensured.

As a further supplementary example, the hall sensor 10 is matched with the deployment scheme of the magnet 20, and is preferably distributed and arranged in a certain inclination angle mode, and the formed sensing area faces the magnet 20, so that when the magnet 20 moves along with the vehicle deflector rod 30 relative to the hall sensor 10, the magnet 20 is always in the sensing range of the hall sensor 10, and the sensing sensitivity is ensured.

As a further supplementary example, the hall sensor 10 may be a 2D hall sensor or a 3D hall sensor, which may be specifically determined according to practical requirements.

When the vehicle deflector rod state detection component arranged in the application example is matched with the deflector rod 30 to act with the steering column switch module 50, the magnet 20 can synchronously move relative to the Hall sensor 10 along with the stirring of the deflector rod 30, and the movement of the magnet 20 is always in the sensing range of the Hall sensor 10, so that the fixed Hall sensor 10 can accurately and highly sensitively detect the movement direction of the magnet 20 and form corresponding sensing signals, the formed sensing signals are synchronously transmitted to the main PCB 60 in the steering column switch module 50 through the flexible circuit board 40, and the main PCB 60 in the steering column switch module 50 can calculate and judge the stirring direction of the vehicle deflector rod according to the signals; on the basis, the main PCB 60 forms corresponding control instructions according to the functions corresponding to the calculated and determined toggle positions of the vehicle deflector rod.

In the vehicle driving lever state detection assembly, the magnet 20 is used as a moving part, and the magnet and the Hall sensor 10 realize electric performance through no contact, so that the functional sensitivity is higher; in practical application, the operation sound is lower, the service life is longer, and the reliability is higher.

In some embodiments of the present utility model, when the present vehicle lever state detection assembly is deployed in a steering column switch module, a hall sensor integrated on a flexible circuit board in the lever may be deployed as a moving component, while a mating magnet is deployed as a fixed component.

Referring to fig. 6, an exemplary diagram of a vehicle lever state detection assembly having the hall sensor 10 as a moving part and the magnet 20 as a fixed part is shown deployed in a steering column switch module 50.

Further, the hall sensor 10 is integrally disposed on the extension of the flexible circuit board 40 in the steering column switch module 50, and the extension of the flexible circuit board 40 in the steering column switch module 50 has a sufficient length and a sufficient deformation margin to enable the hall sensor 10 to be fixedly disposed on the swing portion of the vehicle lever 30 in the steering column switch module 50. The hall sensor 10 thus arranged is capable of generating a corresponding movement in the steering column switch module 50 in synchronism with the actuation of the lever 30.

In cooperation with this, the magnet 20 is directly fixed in the steering column switch module 50 relative to the hall sensor 10 on the vehicle shift lever 30, and is fixedly distributed in the steering column switch module 50 relative to the shift lever 30 and the hall sensor 10 thereon as a fixing member.

Here, the arrangement of the magnet 20 and the hall sensor 10 needs to enable the sensing area of the hall sensor 10 to be located in the effective magnetic field area generated by the magnet 20, that is, when the hall sensor 10 moves with the vehicle shifter 30 relative to the magnet 20, the sensing area is also located in the effective magnetic field area generated by the magnet 20.

As a further illustration, referring to fig. 7, there is shown one example of an application of the vehicle lever state detection assembly with the hall sensor 10 as a moving part and the magnet 20 as a fixed part deployed in the steering column switch module 50.

In order to facilitate the distribution of the hall sensors 10 integrated on the flexible circuit board 40 in the driving lever and ensure the reliability of the cooperation of the two, the magnets 20 are preferably distributed in a manner of a certain inclination angle, so that the hall sensors 10 are given a larger degree of freedom of deployment, and meanwhile, the generated sensing range can always cover the fixedly arranged magnets 20 when the hall sensors 10 move along with the driving lever 30 of the vehicle relative to the magnets 20, so as to ensure the sensing sensitivity.

The magnet 20 is fixedly provided in the steering column switch module 50 by a magnet fixing bracket 21, and the magnet fixing bracket 21 may be integrally formed in the steering column switch module 50 or may be mounted in the steering column switch module 50 by a separate component.

On this basis, the hall sensor 10 is integrally arranged on the extension portion of the flexible circuit board 40 located in the steering column switch module 50, and the specific integrated arrangement position can be determined according to practical requirements.

The extension of the flexible circuit board 40 within the steering column switch module 50 is here a first extension 41, an integration 42 and a second extension 43.

The first extension 41 extends directly along the lower surface of the swing portion of the lever 30 into the steering column switch module 50, and extends to the top end of the swing portion; the first extension part 41 is positioned at the top end part of the swinging part to form an integrated part 42 for integrally arranging the Hall sensor 10;

the second extension 43 is formed outwardly from the middle of the first extension 41, and the second extension 43 serves as an extension transmission part and can adapt to the internal structure of the steering column switch module 50 based on its flexible deformation.

As a further supplementary example, when the hall sensor 10 is fixedly disposed on the swinging portion of the lever 30 in the steering column switch module 50 together with the integrated portion on the flexible circuit board 40, it may be fixed on the swinging portion of the lever 30 in the steering column switch module 50 by riveting or pasting, etc., so that it is ensured that the hall sensor 10 can swing together with the lever 30.

When the vehicle shift lever state detection assembly arranged in the application example is matched with the shift lever 30 to act with the steering column switch module 50, the Hall sensor 10 arranged on the shift lever 30 can move relative to the magnet 20 fixedly arranged in the steering column switch module 50 along with the shifting synchronization of the shift lever 30, and the sensing range of the Hall sensor 10 is always in the magnetic field range generated by the magnet 20, so that the moving Hall sensor 10 can accurately and highly sensitively detect the orientation of the magnet 20 and form corresponding sensing signals, the formed sensing signals are synchronously transmitted to the main PCB 60 in the steering column switch module 50 through the flexible circuit board 40, and the main PCB 60 in the steering column switch module 50 can calculate and judge the shifting orientation of the vehicle shift lever according to the signals; on the basis, the main PCB 60 forms corresponding control instructions according to the functions corresponding to the calculated and determined toggle positions of the vehicle deflector rod.

In the vehicle driving lever state detection assembly, the Hall sensor 10 is used as a moving part, and the electric performance and the magnet 20 are realized through no contact, so that the functional sensitivity is higher; in practical application, the operation sound is lower, the service life is longer, and the reliability is higher.
