Description

Technical Field

[0001] This utility model relates to the field of automotive technology, and in particular to a chassis height sensor and a vehicle. Background Technology

[0002] The chassis height sensor (also known as the suspension height sensor, vehicle height sensor, etc.) is an essential component in automobiles used to measure changes in the attitude of the front and rear suspensions. The vehicle's suspension control system and automatic headlight adjustment system both rely on this sensor to measure changes in the vehicle's driving status.

[0003] Currently, most chassis height sensor products use a linkage structure. The linkage of this type of chassis height sensor is mainly installed in the vehicle chassis. When the vehicle is in motion, the linkage and ball joint convert the vertical movement of the vehicle suspension into the rotation of the sensor, which then outputs the angle signal to the electronic control unit (ECU). Finally, the ECU outputs the chassis height change based on the correspondence between the angle and the chassis height. However, this type of linkage chassis height sensor has a complex structure. Utility Model Content

[0004] The purpose of this invention is to solve the problem of complex structures in existing chassis height sensors. This invention provides a chassis height sensor and vehicle, with a simple structure and no connecting rod bearing transmission mechanism.

[0005] To address the aforementioned technical problems, this utility model discloses a chassis height sensor for installation on a vehicle body. The vehicle body includes a frame, a stabilizer bar, and an electronic control unit. The electronic control unit stores the correspondence between the stabilizer bar rotation angle and the change in chassis height. The chassis height sensor includes: a housing for connecting to the frame; the housing includes an inner cavity; a PCB board installed within the inner cavity; a sensing element installed on the PCB board; the sensing element for measuring the stabilizer bar rotation angle; a magnetic wheel located within the inner cavity, the magnetic wheel having an axial clearance with the sensing element; the magnetic wheel for rotating synchronously with the stabilizer bar; and a connector for electrical connection with the electronic control unit; the connector is electrically connected to the PCB board.

[0006] Using the above technical solution, when the magnetic wheel rotates synchronously with the stabilizer bar, the direction and intensity of its magnetic field will change periodically. The sensing element detects the change in the magnetic field and converts it into a change in electrical signal. By processing and analyzing the electrical signal, the rotation angle of the magnetic wheel can be obtained, and thus the rotation angle of the stabilizer bar. The sensor element measures the rotation angle of the stabilizer bar, which is then transmitted to the electronic control unit via a connector. The electronic control unit, using its stored correlation between the stabilizer bar rotation angle and the change in chassis height, ultimately obtains the change in chassis height.

[0007] In summary, this embodiment directly measures the rotation angle of the stabilizer bar by setting a chassis height sensor to obtain the chassis height change. The chassis height sensor has a simple motion structure, no connecting rod bearing transmission mechanism, and a universal design, making it highly adaptable to different chassis.

[0008] According to another specific embodiment of the present invention, it further includes a fixing plate, which is used to sleeve the stabilizing rod and is interference-fitted with the stabilizing rod; the magnetic wheel is fixedly connected to one end of the fixing plate facing the housing, and the magnetic wheel protrudes outward along the radial direction of the fixing plate.

[0009] Using the above technical solution, the stabilizer bar is fitted onto the fixed plate and is interference-fitted with the stabilizer bar. When the vehicle chassis height changes, the stabilizer bar rotates, and the fixed plate, which is interference-fitted with the stabilizer bar, can drive the magnetic wheel to rotate synchronously. This allows the sensing element to measure the rotation angle of the magnetic wheel and thus obtain the rotation angle of the stabilizer bar.

[0010] According to another specific embodiment of the present invention, the fixing plate includes a first plate body portion and a second plate body portion, the first plate body portion and the second plate body portion are joined together to form a mounting hole, and the stabilizing rod is used to pass through the mounting hole and is interference-fitted with the mounting hole.

[0011] According to another specific embodiment of the present invention, the first disc body and the second disc body are connected by bolts.

[0012] Using the above technical solution, due to the long length of the stabilizer bar and limited space, directly passing the stabilizer bar through the mounting plate may be obstructed and difficult to operate. However, the first and second plate parts can be inserted into the stabilizer bar from both sides, and then the first and second plate parts can be fixedly connected. This eliminates the need to pass the entire stabilizer bar through the mounting hole of the mounting plate, greatly reducing the difficulty of installation and the space requirements.

[0013] According to another specific embodiment of the present invention, the housing includes a connecting hole, the connecting hole including a fan-shaped notch, for the housing to be sleeved on the outside of the stabilizer rod; the housing and the fixing plate are arranged parallel to and spaced apart along the axial direction of the stabilizer rod.

[0014] The above technical solution uses a fan-shaped notch instead of a complete circular hole. This allows the stabilizing rod to pass directly through the notch into the connecting hole, thus enabling the housing to be fitted over the stabilizing rod. This ensures that the housing and the fixed disk are parallel to each other along their axial direction, facilitating the sensing element's detection of changes in the magnetic field caused by the rotation of the magnetic wheel, thereby improving the accuracy and reliability of the measurement.

[0015] According to another specific embodiment of the present invention, the housing includes a cover and a main body. The main body includes a groove, and the PCB board is installed in the groove. The cover covers the groove to define the inner cavity. The cover is sleeved on the outside of the fixed disk and is arranged radially spaced from the fixed disk. Along the axial direction of the fixed disk, the cover is located on the side of the magnetic wheel facing away from the main body.

[0016] With the above technical solution, the cover is fitted over the fixed disk and spaced radially from the fixed disk, which facilitates the fixed disk to drive the magnetic wheel to rotate without causing the fixed disk and the cover to rub against each other.

[0017] In addition, along the axial direction of the fixed disk, the cover is located on the side of the magnetic wheel facing away from the main body, so the magnetic wheel is located between the cover and the main body. The cover and the main body are connected so that the magnetic wheel can extend into the inner cavity to facilitate detection by the sensing element. On the other hand, it also facilitates the physical protection of the magnetic wheel by the housing and the need to reduce noise.

[0018] According to another specific embodiment of the present invention, a fixing member is also included, one end of which is connected to the housing and the other end is used to connect to the vehicle frame.

[0019] By adopting the above technical solution, the fastener connects the housing to the frame, thereby achieving relative fixation of the housing relative to the frame. In other words, the sensing element located in the inner cavity of the housing is fixed in a set position, so that it maintains a relatively stable spatial relationship with the magnetic wheel. This allows the sensing element to accurately sense changes in the magnetic field and convert them into electrical signals, thereby improving the accuracy and reliability of the measurement.

[0020] According to another specific embodiment of this utility model, the sensing element is a Hall chip.

[0021] According to another specific embodiment of the present invention, the magnetic wheel is fan-shaped and the angle of the magnetic wheel is 90° to 180°.

[0022] By adopting the above technical solution, since the rotation range of the stabilizer bar is 0° to 30°, a 360° magnetic ring is not required. In this embodiment, the magnetic wheel angle is selected to be 90° to 180°, which provides sufficient measurement margin on the one hand, and avoids the problems of high cost and material waste caused by using a 360° magnetic ring on the other hand.

[0023] This utility model also discloses a vehicle based on the aforementioned chassis height sensor, comprising: the aforementioned chassis height sensor; and a vehicle body, including a frame, a stabilizer bar, and an electronic control unit; wherein the frame is connected to the housing; the stabilizer bar is connected to the frame; the magnetic wheel of the chassis height sensor is used to rotate synchronously with the stabilizer bar, and the sensing element is used to measure the rotation angle of the stabilizer bar; the electronic control unit is electrically connected to the connector; and the electronic control unit stores the correspondence between the stabilizer bar rotation angle and the change in chassis height.

Therefore, they should not be construed as limitations on the utility model.

[0033] The terms “first”, “second”, etc., are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0034] In the description of this embodiment, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set up," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment based on the specific circumstances.

[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0036] refer to Figure 1 and Figure 2 This application provides a vehicle, including: a chassis height sensor 100 and a vehicle body, the vehicle body including a stabilizer bar 10, wheels 11, shock absorbers 12, connecting rods 13, a frame 14 and an electronic control unit.

[0037] In modern automotive suspension systems, the stabilizer bar 10 plays an indispensable role as a crucial auxiliary elastic element. One of its core functions is to coordinate the left and right wheels 11 (…). Figure 1 (Only the left wheel is shown) effectively stabilizes the vehicle body when it bounces up and down. When the vehicle is traveling on complex road conditions, such as potholes, bumps, or uneven surfaces, the wheel 11 will inevitably move up and down. During this process, when the wheel 11 moves upward, the chassis height will decrease accordingly, and the shock absorber 12 connected to it will be subjected to an upward force, which will drive the connecting rod 13 to move upward. Since the connecting rod 13 is connected to the stabilizer bar 10, the upward movement of the connecting rod 13 will pull the stabilizer bar 10 to rotate.

[0038] Therefore, in this embodiment, based on the torsional motion of the stabilizer bar 10 when the chassis height changes, the change in chassis height is obtained by measuring the rotation angle of the stabilizer bar 10.

[0039] The specific structure of the chassis height sensor 100 will be described in detail below with reference to the accompanying drawings.

[0040] refer to Figures 2 to 5 The chassis height sensor 100 includes a housing 200, a PCB board 300, a sensing element 400, a magnetic wheel 500, and a connector 600. The housing 200 is used to connect to the vehicle frame 14; the housing 200 includes an inner cavity 201. Figure 5 (As shown). The PCB board 300 is mounted inside the inner cavity 201. Exemplarily, the PCB board 300 is snapped onto the cavity wall of the inner cavity 201.

[0041] The sensing element 400 is mounted on the PCB board 300. For example, the sensing element 400 is a Hall chip.

[0042] For example, the PCB board 300 and the sensing element 400 are located inside the cavity 201 of the housing 200, so that on the one hand, the housing 200 supports the PCB board 300 and the sensing element 400 to ensure their relative position is fixed, and on the other hand, the cavity 201 of the housing 200 provides physical protection and electromagnetic shielding for the PCB board 300 and the sensing element 400.

[0043] The aforementioned magnetic wheel 500 is located within the inner cavity 201. The magnetic wheel 500 and the sensing element 400 have an axial clearance, and there is no direct contact between the magnetic wheel 500 and the sensing element 400, thereby avoiding wear caused by direct friction, reducing the wear of parts, and extending the service life of the magnetic wheel 500 and the sensing element 400.

[0044] The magnetic wheel 500 is used to rotate synchronously with the stabilizer bar 10 so that the sensing element 400 can measure the rotation angle of the stabilizer bar 10.

[0045] Specifically, when the magnetic wheel 500 rotates synchronously with the stabilizer bar 10, the direction and intensity of its magnetic field change periodically. The sensing element 400 operates based on the principle of electromagnetic induction, which can sense the changes in the magnetic field and convert them into changes in electrical signals. By processing and analyzing the electrical signals, the rotation angle of the magnetic wheel 500 can be obtained, and thus the rotation angle of the stabilizer bar 10 can be obtained.

[0046] Connector 600 is used for electrical connection with electronic control unit; connector 600 is also electrically connected to PCB board 300. That is, connector 600 electrically connects PCB board 300 to electronic control unit, so that the rotation angle of stabilizer bar 10 measured by sensing element 400 can be transmitted to electronic control unit through connector 600.

[0047] The aforementioned electronic control unit stores the correspondence between the rotation angle of the stabilizer bar 10 and the change in chassis height. When the sensing element 400 measures the rotation angle of the stabilizer bar 10 and transmits it to the electronic control unit through the connector 600, the electronic control unit can obtain the change in chassis height based on the stored correspondence between the rotation angle of the stabilizer bar 10 and the change in chassis height.

[0048] Using the above technical solution, when the magnetic wheel 500 rotates synchronously with the stabilizer bar 10, the direction and intensity of its magnetic field will change periodically. The sensing element 400 senses the change in the magnetic field and converts it into a change in electrical signal. By processing and analyzing the electrical signal, the rotation angle of the magnetic wheel 500 can be obtained, and thus the rotation angle of the stabilizer bar 10 can be obtained. The sensing element 400 measures the rotation angle of the stabilizer bar 10 and transmits it to the electronic control unit through the connector 600. The electronic control unit obtains the change in chassis height by using the correspondence between the rotation angle of the stabilizer bar 10 and the change in chassis height stored in its memory. Since the sensing element 400 outputs an angle signal, the change in chassis height can be obtained by using the correspondence between the rotation angle of the stabilizer bar 10 and the change in chassis height stored in the electronic control unit, thus the electronic control unit does not need to change its hardware.

[0049] In summary, this embodiment directly measures the rotation angle of the stabilizer bar 10 by setting a chassis height sensor 100 to obtain the chassis height change. The chassis height sensor 100 has a simple motion structure, no connecting rod or bearing transmission mechanism, and a universal design, making it highly adaptable to different chassis. Furthermore, the chassis height sensor 100 in this embodiment is installed far from the area splashed by the wheels 11, providing a good working environment and preventing mud and sand kicked up by the rotating wheels 11 from hitting the chassis height sensor 100 and causing damage.

[0050] In some possible implementations, such as Figures 3 to 5As shown, the chassis height sensor 100 also includes a fixed plate 700, which is used to mount the stabilizer bar 10 and is interference-fitted with the stabilizer bar 10. A magnetic wheel 500 is fixedly connected to the end of the fixed plate 700 facing the housing 200, and the magnetic wheel 500 protrudes outward along the radial direction X of the fixed plate 700. For example, the fixed plate 700 is located outside the inner cavity 201, and it mounts the stabilizer bar 10 and is interference-fitted with the stabilizer bar 10. When the vehicle chassis height changes, the stabilizer bar 10 rotates, and the fixed plate 700, which is interference-fitted with the stabilizer bar 10, can drive the magnetic wheel 500 to rotate synchronously. The magnetic wheel 500 rotates within the inner cavity 201, so that the sensing element 400 can obtain the rotation angle of the stabilizer bar 10 by measuring the rotation angle of the magnetic wheel 500.

[0051] In some possible implementations, such as Figure 3 As shown, the fixed disk 700 includes a first disk body portion 701 and a second disk body portion 702. The first disk body portion 701 and the second disk body portion 702 are joined together to form a mounting hole 703. The stabilizing rod 10 is used to pass through the mounting hole 703 and is interference-fitted with the mounting hole 703. In this embodiment, both the first disk body portion 701 and the second disk body portion 702 are semi-circular in shape. The two are joined together to form a fixed disk 700 that is circular in shape as a whole, and the mounting hole 703 is formed at the center of the fixed disk 700.

[0052] For example, due to the relatively long length of the stabilizer bar 10 and limited space, directly passing the stabilizer bar 10 through the mounting plate 700 may be obstructed and difficult to operate. However, the semi-circular first plate portion 701 and the second plate portion 702 can be inserted from both sides of the stabilizer bar 10 respectively, and then the first plate portion 701 and the second plate portion 702 can be fixedly connected. This eliminates the need to pass the entire stabilizer bar 10 through the mounting hole 703 of the mounting plate 700, greatly reducing the difficulty of installation and the requirements for installation space.

[0053] In this embodiment, both the first disc portion 701 and the second disc portion 702 are semi-circular rings. However, those skilled in the art will understand that in other embodiments, the first disc portion 701 and the second disc portion 702 may also be other fan-shaped rings. For example, the first disc portion 701 may be a fan-shaped ring with a central angle of 100°, and correspondingly, the second disc portion 702 may be a fan-shaped ring with a central angle of 260°.

[0054] In this embodiment, the first disc portion 701 and the second disc portion 702 are connected by bolts. Specifically, both the first disc portion 701 and the second disc portion 702 have interconnected bolt holes 704. A single bolt passing through both bolt holes 704 securely connects the first disc portion 701 and the second disc portion 702, forming a circular fixed disc 700. A mounting hole 703 for the stabilizing rod 10 is formed at the center of the fixed disc 700. However, those skilled in the art will understand that in other embodiments, other methods can be used to connect the first disc portion 701 and the second disc portion 702, such as welding or snap-fitting.

[0055] In some possible implementations, such as Figure 4 and Figure 5 As shown, the housing 200 includes a cover 210 and a main body 220. The main body 220 includes a groove 230, a PCB board 300 is snapped into the groove 230, a magnetic wheel 500 extends into the groove 230, and the cover 210 covers the groove 230 to define the inner cavity 201. The cover 210 is sleeved on the outside of the fixed disk 700 and is spaced apart from the fixed disk 700 along the radial direction X of the fixed disk 700, so that the fixed disk 700 can drive the magnetic wheel 500 to rotate without causing the fixed disk 700 and the cover 210 to rub against each other.

[0056] Along the axial direction Z of the fixed disk 700 (that is, the axial direction of the stabilizer bar 10), the cover 210 is located on the side of the magnetic wheel 500 facing away from the main body 220. The magnetic wheel 500 is located between the cover 210 and the main body 220. The cover 210 and the main body 220 are connected so that the magnetic wheel 500 extends into the inner cavity 201, so that the sensing element 400 can detect it. On the other hand, it also facilitates the physical protection of the magnetic wheel 500 by the housing 200 and the need to reduce noise.

[0057] In some possible implementations, a fixing member 800 is also included, one end of which is connected to the housing 200, and the other end is used to connect to the frame 14. That is, the fixing member 800 connects the housing 200 to the frame 14, thereby achieving relative fixation of the housing 200 relative to the frame 14. In other words, the sensing element 400 located in the inner cavity 201 of the housing 200 is fixed in a set position, so that it maintains a relatively stable spatial relationship with the magnetic wheel 500, so that changes in the magnetic field can be accurately sensed by the sensing element 400 and converted into an electrical signal, thereby improving the accuracy and reliability of the measurement.

[0058] For example, such as Figure 2 and Figure 6As shown, the fastener 800 is in the shape of an "I" and includes a first connecting portion 810 and a second connecting portion 820 that are in the form of a sheet. The first connecting portion 810 is snapped into the housing 200. The frame 14 includes a protrusion 140 with a through hole (not labeled in the figure) for the stabilizer bar 10 to pass through, thereby connecting the stabilizer bar 10 and the frame 14. The second connecting portion 820 of the fastener 800 is welded to the protrusion 140. To increase the contact area between the second connecting portion 820 and the protrusion 140, the second connecting portion 820 has two bends 821. A portion of the bends 821 fits against the protrusion 140, thereby achieving a better welding effect.

[0059] However, those skilled in the art will understand that in other embodiments, the connection between the fastener 800, the housing 200, and the frame 14 can also be achieved in other ways, such as screw connection.

[0060] In some possible embodiments, the housing 200 includes a connecting hole 202, which includes a fan-shaped notch 203 for the housing 200 to be fitted over the stabilizer rod 10. The housing 200 and the fixed disk 700 are parallel to and spaced apart along the axial direction Z of the stabilizer rod 10. Exemplarily, the connecting hole 202 is not a complete circular hole; the fan-shaped notch 203 is at 110°, allowing the stabilizer rod 10 to directly enter the connecting hole 202 through the fan-shaped notch 203. This allows the housing 200 to be fitted over the stabilizer rod 10, ensuring that the housing 200 and the fixed disk 700 are parallel along their axial direction. This facilitates the sensing element 400 in sensing changes in the magnetic field caused by the rotation of the magnetic wheel 500, thereby improving the accuracy and reliability of the measurement.

[0061] In some possible implementations, the magnetic wheel 500 is fan-shaped, with an angle ranging from 90° to 180°. For example, since the stabilizer bar 10 rotates within a range of 0° to 30°, a 360° magnetic ring is unnecessary. This embodiment uses a 120° angle for the magnetic wheel 500, providing sufficient measurement margin while avoiding the high cost and material waste associated with using a 360° magnetic ring. However, those skilled in the art will understand that in other embodiments, the magnetic wheel 500 can also be selected with other angles, such as 90°, 120°, 150°, 180°, etc.

[0062] Although the present invention has been illustrated and described with reference to certain preferred embodiments, those skilled in the art should understand that the above description is a further detailed explanation of the present invention in conjunction with specific embodiments, and should not be construed as limiting the specific implementation of the present invention to these descriptions. Those skilled in the art can make various changes in form and detail, including some simple deductions or substitutions, without departing from the spirit and scope of the present invention.
