Description

Technical Field

[0001] This utility model relates to the field of automotive suspension technology, and in particular to a vehicle height sensor mounting structure. Additionally, this utility model also relates to a vehicle. Background Technology

[0002] The suspension system is an essential component of a car, encompassing all force-transmitting connections between the chassis, axles, and wheels. Traditional technologies often employ passive suspensions such as steel spring suspensions and hydraulic suspensions. However, with advancements in automotive technology, semi-active and active suspensions based on controllable suspension technology are increasingly being used in high-end models. In active suspension systems, a vehicle height sensor is used to detect the vehicle's height (the relative displacement between the vehicle body and the lower suspension arm or shock absorber support in the vertical direction) to allow for control of the suspension system based on the vehicle's current height.

[0003] However, in practical applications, the installation of the vehicle height sensor within the suspension system is limited by space constraints. Improper installation design can create difficulties in sensor assembly and affect the accuracy and stability of vehicle height detection. When the detected vehicle height signal does not correspond to the actual height, it severely impacts the active adjustment of the suspension, preventing the system from reacting appropriately in a timely manner. This increases driving risks for the driver and compromises driving safety. Utility Model Content

[0004] In view of this, the present invention aims to propose a vehicle height sensor mounting structure to provide a vehicle height sensor mounting solution that is easy to disassemble and maintain.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] A vehicle height sensor mounting structure includes a mounting bracket, a connector, and a linkage mechanism. The mounting bracket supports the sensor body and is fixed to a vehicle-side mounting base by threaded fasteners. The connector is screwed to the suspension-side mounting base, and the linkage mechanism is drively connected between the sensor body and the connector. When the connector moves relative to the mounting bracket, the linkage mechanism can drive the sensor shaft of the sensor body to rotate.

[0007] Furthermore, the mounting bracket includes a fixing plate for connecting the vehicle side mounting base, a mounting plate for fixing the sensor body, and an extension plate connecting the fixing plate and the mounting plate; the fixing plate is provided with a first mounting hole for inserting the threaded fastener, and the mounting plate is provided with a second mounting hole for mounting the sensor body.

[0008] Furthermore, the fixing plate is located at one end of the extension plate and is bent toward one side of the extension plate, and the mounting plate is located at the other end of the extension plate and is bent toward the other side of the extension plate.

[0009] Furthermore, the sensor body is located on the side of the mounting plate facing the fixed plate, and the extension plate covers the upper part of the sensor body; the linkage mechanism is located on the side of the mounting plate facing away from the fixed plate, and the mounting plate is provided with a through hole for the linkage mechanism to connect to the sensor shaft.

[0010] Furthermore, the fixing plate is provided with a first limiting plate, which is inserted into a limiting hole on the vehicle side mounting base to restrict the rotation of the mounting bracket relative to the vehicle side mounting base; and / or, the mounting plate is provided with an anti-rotation baffle, which limits the rotation angle range of the sensor shaft.

[0011] Furthermore, the connector includes a base plate for connecting the suspension-side mounting base and a connecting plate located at the edge of the base plate, the linkage mechanism is connected to the connecting plate, and the base plate is provided with a third mounting hole for threading a screw; or, the connector includes a connecting seat for connecting the linkage mechanism and a stud provided on the connecting seat, the stud being screwed and fixedly connected to the suspension-side mounting base.

[0012] Furthermore, the linkage mechanism includes a swing arm fixed to the sensor shaft, and a connecting rod with its two ends respectively hinged to the swing arm and the connecting member.

[0013] Furthermore, the swing arm is connected to one end of the connecting rod via a first ball joint pin, and the connecting piece is connected to the other end of the connecting rod via a second ball joint pin.

[0014] Furthermore, the ball head of the second ball head pin is located in the ball head seat at the end of the connecting rod, and the pin shaft of the second ball head pin is riveted to the connecting member.

[0015] Compared with the prior art, this utility model has the following advantages:

[0016] This utility model discloses a vehicle height sensor mounting structure. It includes two brackets: one for mounting the sensor body on the vehicle side mounting base, and the other for connecting the linkage mechanism of the detection device to the suspension side mounting base. When the suspension moves up and down relative to the vehicle body, the suspension side mounting base drives the sensor shaft to rotate via the linkage mechanism, which is then converted into a height signal by the sensor body. Both brackets are fixed to the corresponding mounting base using mounting holes and fasteners, facilitating disassembly, replacement, and maintenance. This provides a convenient vehicle height sensor mounting solution for disassembly and maintenance.

[0017] In addition, the mounting bracket is designed with three parts: a fixed plate, an extension plate, and a mounting plate. These parts are used to connect the mounting base on the side of the vehicle body, install the sensor body, and form a connecting support between the fixed plate and the mounting plate, respectively. This allows the mounting plate to be placed in a more suitable position. In this way, the linkage mechanism can be well arranged in the height direction of the vehicle body. When the suspension moves up and down, the sensor shaft of the sensor body can be driven to rotate well through the linkage mechanism, making the transmission effect smoother.

[0018] Furthermore, the linkage mechanism employs a hinged transmission, with the linkage driving the swing arm to swing. This effectively detects the relative movement between the vehicle-side mounting base and the suspension-side mounting base, and can accommodate relative movement between them in the vertical and longitudinal directions. The ball-joint connection at both ends of the linkage not only accommodates the relative movement of the vehicle-side and suspension-side mounting bases in the vertical and longitudinal directions, but also overcomes the need for relative movement between the two mounting bases in the lateral direction.

[0019] Another objective of this invention is to provide a vehicle in which the vehicle suspension system is equipped with the vehicle height sensor mounting structure described in this invention. The vehicle of this invention possesses the technical advantages of the aforementioned vehicle height sensor mounting structure. Attached Figure Description

[0036] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0037] Example 1

[0038] This embodiment relates to a vehicle height sensor mounting structure, providing a convenient installation solution for a vehicle height sensor that is easy to install and maintain; one exemplary structure is as follows: Figure 1 , Figure 2 and Figure 3 As shown.

[0039] Overall, the vehicle height sensor mounting structure includes a mounting bracket 4, a connector 5, and a linkage mechanism. The mounting bracket 4 supports the sensor body 3 and is fixed to the vehicle-side mounting base 1 using threaded fasteners. The connector 5 is screwed to the suspension-side mounting base 2, and the linkage mechanism connects the sensor body 3 and the connector 5. When the connector 5 moves relative to the mounting bracket 4, the linkage mechanism drives the sensor shaft 300 of the sensor body 3 to rotate.

[0040] It should be noted that, based on the above-mentioned overall design concept, the technical solution of this utility model can adopt a variety of different specific implementation structures, forms, or configuration sequences. For example, the above-mentioned linkage mechanism can adopt various specific structural forms such as gear and rack transmission and linkage transmission; the specific arrangement sequence and assembly method of each bracket and linkage can also be flexibly adjusted. For the parts required for the implementation of the overall solution but not covered in the above-mentioned overall setup, reasonable and flexible design can be carried out by referring to mature setup methods in the field and the actual situation during implementation. The specific implementation schemes described below in this embodiment are only one of the many solutions that can be formed by the above-mentioned combinations and variations. In actual implementation, those skilled in the art can make flexible adjustments and improvements based on the actual situation. Obviously, the many solutions that can be formed by the above-mentioned combinations and variations, as well as the specific implementation schemes of this embodiment, are all within the protection scope of this utility model.

[0041] Figure 1 A schematic diagram is provided illustrating the application of the mounting structure of this embodiment to a vehicle's suspension system. The vehicle-side mounting base 1 in the diagram can be the vehicle frame, and the suspension-side mounting base 2 can be the lower control arm or shock absorber lower bracket in the suspension. In existing technologies, when installing a height sensor between a fixed component (vehicle body, subframe, etc.) and a moving component (suspension component), welding is generally used. The bracket is pre-welded to the subframe and control arm. The subframe and control arm are prone to impacts during individual transport, often causing deformation and damage to the bracket. Furthermore, damaged brackets cannot be replaced during vehicle use, making repair difficult. Simultaneously, for welding purposes, the bracket needs to be made of the same material as the subframe and control arm. When the base component is iron, aluminum or steel cannot be used for the bracket and other mounting components, limiting material availability and hindering overall lightweight design. Moreover, the limited space between the suspension and the vehicle body restricts assembly space, resulting in complex structures and difficult assembly in existing designs.

[0042] The vehicle height sensor mounting structure of this invention features a compact design for the mounting bracket 4 and connector 5, which are assembled using a screw connection, eliminating the bracket deformation issues caused by pre-welding and adapting to situations with limited installation space. After the sensor body 3 and its linkage mechanism are stably installed in place using the mounting bracket 4 and connector 5, when the relative position between the vehicle-side mounting base 1 and the suspension-side mounting base 2 changes, the linkage mechanism drives the sensor shaft 300 of the sensor body 3 to rotate, thereby causing a change in the sensor's detection signal. This signal is then sent to the suspension system control unit for corresponding control and suspension adjustments.

[0043] The aforementioned sensor body 3 can utilize a readily available and mature vehicle height sensor. Inside this sensor is a sensor shaft 300, driven to rotate by a connecting rod. A disc with numerous narrow slots is fixed to the sensor shaft 300. The shader consists of a light-emitting diode and a photodiode transistor. The rotation of the disc with the sensor shaft 300 allows for ON / OFF switching of the shader's output, and this ON / OFF switch signal is transmitted to the suspension electronic control unit via a signal line. Based on this ON / OFF switching, the electronic control unit can detect the rotation angle of the disc. When the vehicle height changes, i.e., when the suspension deformation changes, the connecting rod mechanism drives the sensor shaft 300 to rotate, causing the disc to rotate under the influence of the sensor shaft 300, thus enabling the electronic control unit to detect the change in vehicle height.

[0044] For the mounting bracket 4 and connector 5, there are naturally many different structural options available. In this embodiment, such as... Figure 2 , Figure 3 As shown, the mounting bracket 4 includes a fixing plate 40 for connecting to the vehicle-side mounting base 1, a mounting plate 42 for fixing the sensor body 3, and an extension plate 41 connecting the fixing plate 40 and the mounting plate 42. The fixing plate 40 has a first mounting hole 400. The threaded fastener for fixing the mounting bracket 4 is preferably a hexagonal flange bolt 601. The hexagonal flange bolt 601 passes through the first mounting hole 400 and is screwed onto the vehicle-side mounting base 1, thus fixing the mounting bracket 4 to the vehicle body.

[0045] The sensor body 3 is fastened to the mounting plate 42 using threaded fasteners. Of course, the number and position of the first mounting holes 400 on the mounting plate 40 can be flexibly set. In this embodiment, the mounting plate 40 only has one first mounting hole 400 in the middle. Combined with the first limiting insert 401 on the mounting plate 40, this ensures the secure installation of the mounting bracket 4 on the vehicle side mounting base 1. The mounting plate 42 has two through holes. The sensor body 3 is fastened to the mounting plate 42 by screwing internal Torx screws 602 through these holes. Alternatively, internal Torx screws 602 can be replaced with threaded fasteners such as hexagonal socket head cap screws.

[0046] The mounting bracket 4 is designed with three parts: a fixed plate 40, an extension plate 41, and a mounting plate 42. These parts are used to connect the vehicle side mounting base 1, mount the sensor body 3, and form a connecting support between the fixed plate 40 and the mounting plate 42, respectively. The mounting plate 42 can be placed in a more suitable position. In the actual structure, the vehicle side mounting base 1 (such as the frame) and the suspension side mounting base 2 (such as the suspension bracket) are not directly opposite each other in the vehicle height direction. After the fixed plate 40 is fixed on the frame, the extension plate 41 extends to directly below the suspension bracket. In this way, the linkage mechanism can be well arranged in the vehicle height direction. When the suspension moves up and down, the sensor shaft 300 of the sensor body 3 can be rotated well through the linkage mechanism, making the transmission effect smoother.

[0047] The preferred shape for the mounting bracket 4 is as follows: The fixing plate 40 is located at one end of the extension plate 41 and is bent towards one side of the extension plate 41; the mounting plate 42 is located at the other end of the extension plate 41 and is bent towards the other side of the extension plate 41. The mounting bracket 4 employs a two-bending structure, which not only facilitates processing but also creates a good arrangement, allowing the fixing plate 40 and mounting plate 42 to be staggered vertically, preventing interference when the fixing plate 40 is installed on the vehicle side mounting base 1 and when the sensor body 3 is installed on the mounting plate 42. With this configuration, the axial distance between the first mounting hole 400 and the first ball joint pin 32 on the fixing plate 40 can be increased to over 20mm, providing more space for the sensor body 3 and the linkage mechanism to be installed and disassembled more conveniently.

[0048] Based on the aforementioned mounting bracket 4 configuration, in this embodiment, the sensor body 3 is located on the side of the mounting plate 42 facing the fixed plate 40, with the extension plate 41 shielding the sensor body 3 from above. Correspondingly, the linkage mechanism is located on the side of the mounting plate 42 facing away from the fixed plate 40, with the linkage mechanism and sensor body 3 respectively located on opposite sides of the mounting plate 42. The mounting plate 42 has a through hole 420 for the linkage mechanism to connect to the sensor shaft 300, and the aforementioned through holes for fixing the sensor body 3 are provided around the through hole 420. The sensor body 3 is located on the side of the mounting plate 42 facing the fixed plate 40, and the extension plate 41 provides good protection for the sensor body 3 from above. The sensor body 3 and the linkage mechanism are respectively located on opposite sides of the mounting plate 42, effectively isolating the transmission components and the sensor body 3, making the overall arrangement of the detection device more reasonable, and further eliminating the possibility of the sensor body 3 being damaged by collision.

[0049] In addition, the fixing plate 40 of this embodiment is provided with a first limiting plate 401, which is inserted into the limiting hole on the vehicle side mounting base 1 to restrict the rotation of the mounting bracket 4 relative to the vehicle side mounting base 1. Alternatively, anti-rotation baffles 421 can be provided on the mounting plate 42 to limit the rotation angle range of the sensor shaft 300. Specifically, the mounting plate 42 of this embodiment is provided with two anti-rotation baffles 421. The swing arm 30 described below swings between these two anti-rotation baffles 421, thereby limiting the linkage mechanism to move between the two anti-rotation baffles 421, thus constraining the rotation angle range of the sensor shaft 300. A first limiting plate 401 is provided on the fixed plate 40 to enable the fixed plate 40 to be positioned and installed on the vehicle side mounting base 1. In this way, only a first mounting hole 400 is opened on the fixed plate 40, and a single threaded fastener is used to firmly install the mounting bracket 4 onto the vehicle side mounting base 1. This not only makes the installation operation more convenient, but is also more suitable for the poor installation conditions and small installation space on the vehicle side mounting base 1. Two anti-rotation baffles 421 are provided on the mounting plate 42 to limit the range of motion of the linkage mechanism. Specifically, it can limit the swing range of the swing arm 30, thereby limiting the rotation angle range of the sensor shaft 300. This ensures that the vehicle side mounting base 1 will not detect out of range, avoids abnormal damage to the sensor, and can control the measurement accuracy of the height sensor.

[0050] There are, of course, various structural forms for the connector 5. In this embodiment, such as... Figure 3 As shown, the connector 5 includes a base plate 50 for connecting to the suspension-side mounting base 2, and a connecting plate 51 bent into shape at the edge of the base plate 50. The aforementioned linkage mechanism is connected to the connecting plate 51. Based on this, a third mounting hole 500 is provided on the base plate 50, and a second limiting plate 501 is provided on the base plate 50. The second limiting plate 501 engages with the limiting hole on the suspension-side mounting base 2, thereby restricting the connector 5 from rotating relative to the suspension-side mounting base 2. The connector 5 adopts a bent structure of the base plate 50 and the connecting plate 51, resulting in a simple installation structure. This facilitates installation on the suspension-side mounting base 2 while also allowing the linkage mechanism to be well connected to the connecting plate 51. Similar to the arrangement of the first limiting plate 401, the second limiting plate 501 makes positioning and installation of the base plate 50 on the suspension-side mounting base 2 more convenient and also accommodates situations where installation conditions on the suspension-side mounting base 2 are limited.

[0051] In this embodiment, only one third mounting hole 500 is formed on the substrate 50. Both the first mounting hole 400 and the third mounting hole 500 are secured with hexagonal flange bolts 601. The mounting bracket 4 and the connector 5 are screwed and fixed to the corresponding mounting base using the hexagonal flange bolts 601. With this configuration, the distance between the third mounting hole 500 and the second ball head pin 33 can be increased to more than 20mm, similar to the configuration of the first mounting hole 400 on the mounting bracket 4. Because the distance between the linkage mechanism and the mounting hole is guaranteed, there is more operating space when assembling the hexagonal flange bolts 601 into the first mounting hole 400 and the third mounting hole 500, which improves the convenience of disassembly and assembly.

[0052] The specific configuration of the linkage mechanism can be flexibly configured. In this embodiment, the linkage mechanism includes a swing arm 30 fixed to the sensor shaft 300, and a connecting rod 31 with its two ends hinged to the swing arm 30 and the connecting member 5, respectively. The linkage mechanism adopts a linkage hinge transmission form, with the connecting rod 31 driving the swing arm 30 to swing. This can effectively detect the relative movement between the vehicle-side mounting base 1 and the suspension-side mounting base 2, and can adapt to the relative movement between the vehicle-side mounting base 1 and the suspension-side mounting base 2 in the vertical and longitudinal directions of the vehicle.

[0053] Furthermore, the control arm 30 is connected to one end of the connecting rod 31 via the first ball joint pin 32, and the connecting piece 5 is connected to the other end of the connecting rod 31 via the second ball joint pin 33. The ball joint connection at both ends of the connecting rod 31 not only satisfies the relative movement of the vehicle-side mounting base 1 and the suspension-side mounting base 2 in the vertical and longitudinal directions of the vehicle, but also overcomes the need for relative movement between the two mounting bases in the lateral direction of the vehicle.

[0054] Regarding the connection at both ends of the connecting rod 31, the pin shaft of the first ball head pin 32 located at the bottom end of the connecting rod 31 can be directly welded to the rocker arm 30, or the entire first ball head pin 32 can be integrally cast with the connecting rod 31, and the ball head of the first ball head pin 32 can be directly assembled into the ball seat at the bottom end of the connecting rod 31. The ball head 330 of the second ball head pin 33 is located in the ball seat at the end of the connecting rod 31, and the pin shaft 331 of the second ball head pin 33 is riveted to the connecting piece 5. The riveting method between the pin shaft 331 of the second ball head pin 33 and the connecting piece 5 not only meets the installation requirements of the detection device but also ensures stable and reliable connection performance. Specifically, the second ball head pin 33 at the top of the connecting rod 31 is riveted to the connecting plate 51. The connecting plate 51 has a riveting hole. The pin 331 of the second ball head pin 33 is inserted into the riveting hole and then pressed and riveted to fix it. The riveting connection is adopted. After the pin 331 is riveted, the axial protrusion length is controlled to be less than 0.5mm. Compared with the bolt connection, the axial space is reduced from 10mm to 0.5mm, which can save 95% of the installation space.

[0055] In summary, the vehicle height sensor mounting structure of this embodiment uses two brackets, one for mounting the sensor body 3 on the vehicle side mounting base 1 and the other for connecting the linkage mechanism of the detection device with the suspension side mounting base 2. When the suspension moves up and down relative to the vehicle body, the suspension side mounting base 2 drives the sensor shaft 300 to rotate through the linkage mechanism, which is then converted into a height signal by the sensor body 3. Both brackets are fixed to the corresponding mounting bases using mounting holes and fasteners, facilitating disassembly, replacement, and maintenance. This provides a convenient vehicle height sensor mounting solution for disassembly and maintenance.

[0056] Example 2

[0057] This embodiment also relates to a vehicle height sensor mounting structure, providing another mounting structure solution that also features easy disassembly and maintenance; one exemplary structure is as follows: Figure 4 , Figure 5 and Figure 6 As shown.

[0058] In terms of overall design concept, the vehicle height detection device in this embodiment is the same as that in embodiment one. Except for the specific structural settings of the mounting bracket 4 and the connector 5, the settings of the linkage mechanism, sensor body 3 and other parts can be implemented with reference to the situation in embodiment one.

[0059] Regarding the specific structure of mounting bracket 4, such as Figure 7 As shown, the overall structure is similar to the mounting bracket 4 provided in Embodiment 1, also including a bent and connected fixing plate 40, an extension plate 41, and a mounting plate 42. The fixing plate 40 has a first mounting hole 400 for inserting hexagonal flange bolts 601 to secure the vehicle side mounting base 1. The mounting plate 42 has two second mounting holes 422 for inserting internal Torx screws 602 to secure the sensor body 3. The difference lies in that the bent portions of the fixing plate 40 and the extension plate 41 in this embodiment are provided with reinforcing protrusions 410, which improves the overall structural stability of the mounting bracket 4.

[0060] Meanwhile, the through hole 420 on the mounting plate 42 in this embodiment has a notch on one side, that is, a notch connecting the through hole 420 is provided at one side edge of the mounting plate 42, which facilitates the installation of the sensor body 3 and the setting of the sensor shaft 300 of the sensor body 3 at that location.

[0061] For connector 5, the following solution is adopted in this embodiment. Figure 6As shown, the connector 5 in this embodiment includes a connecting seat 52 for connecting the linkage mechanism and a stud 520 disposed on the connecting seat 52. The stud 520 is screwed and fixedly connected to the suspension-side mounting base 2; the pin 331 of the second ball-head pin 33 is fixedly connected to the connecting seat 52. The specific fixing method between the pin 331 and the connecting seat 52 can be either screwed or welded. By adopting the structural form of the connector 5 in this embodiment, the overall structural size of the connector 5 can be further reduced, making it more suitable for situations where installation conditions and space are limited on the suspension-side mounting base 2, which is a moving part.

[0062] For the structural design of other parts of this embodiment, the same as in Embodiment 1 can be used, and will not be repeated here. The vehicle height detection device in this embodiment also features easy disassembly, replacement, and maintenance, thus providing another convenient vehicle height sensor installation scheme. Embodiment 3

[0063] This embodiment relates to a vehicle whose suspension system is equipped with the vehicle height sensor mounting structure provided in Embodiment 1.

[0064] The vehicle height sensor mounting structure of this invention solves the problems of limited space and inconvenient installation between the vehicle-side mounting base 1 and the suspension-side mounting base 2. Specifically, the mounting bracket 4 on the vehicle-side mounting base 1 and the connector 5 on the suspension-side mounting base 2 are both installed using threaded fasteners, making assembly and disassembly more convenient. The bracket and the connected mounting base are connected using bolts, which is suitable for non-ferrous materials, broadening its applicability and improving its adaptability. This allows it to meet the installation conditions of different vehicle suspension systems and the needs of vehicle height detection.
