Description

Technical Field

[0001] The present invention relates to a vehicle system component, which comprises a first body, on which a scanning belt with a plurality of scanning elements is fixedly arranged; a second body, which can be moved relative to the first body in a movement direction, wherein a linear displacement sensor is arranged on the second body and cooperates with the scanning belt; and an evaluation unit, which is constructed to determine the linear position of the first body relative to the second body based on a sensor signal of the linear displacement sensor. Background Art

[0002] For example, WO 2021 / 156930 A1 describes a variant embodiment of a linear displacement sensor, in which the linear displacement sensor cooperates with a scanning belt. The scanning belt is fixed to a first body, and the linear displacement sensor is fixed to a second body that is movable relative to the first body. The scanning belt has a plurality of scanning elements, which are scanned by the linear displacement sensor, based on which the position of the first body accommodating the scanning belt relative to the second body accommodating the linear displacement sensor is determined with the aid of an evaluation unit or an evaluation circuit.

[0003] The problem is that displacements of the linear displacement sensor transverse to the direction of motion, tilting and rotations relative to the scanning belt lead to distortions of the sensor signal of the linear displacement sensor. In addition, the air gap between the linear displacement sensor and the scanning belt is required to be as small as possible and the same over the entire measuring path. Summary of the invention

[0004] It is therefore an object of the present invention to provide a vehicle system component by means of which the position of the bodies relative to one another can be reliably determined. This object should be achieved in a simple manner.

[0005] This object is achieved by the features of claim 1 .

[0006] According to the present invention, the linear displacement sensor is supported on the second body in a fixed manner in the movement direction and is supported on the second body in a movable manner transversely to the movement direction.

[0007] The direction of movement corresponds to the longitudinal direction of the scanning belt, wherein the scanning element has a plurality of scanning elements arranged side by side in the longitudinal direction, which scanning elements are detected by linear displacement sensors. Based on the sensor signals of the linear displacement sensors, the position of the bodies relative to each other is determined. The scanning belt preferably has two rows of scanning elements extending parallel to each other, wherein the two rows of scanning elements are arranged offset from each other, that is, the spacing between the scanning elements of the first row is different from the spacing between the scanning elements of the second row.

[0008] “Mounted movably transversely to the direction of movement” means, for example, that in the coordinate system of the vehicle it is assumed that the direction of movement is oriented in the longitudinal direction of the vehicle and the linear displacement sensor is mounted movably in the vertical direction of the vehicle and / or in the transverse direction of the vehicle on the second body.

[0009] By means of such a support of the linear displacement sensor, the linear displacement sensor can be moved together with the second body with high precision in the direction of movement, i.e. in the longitudinal direction of the scanning tape, wherein manufacturing tolerances and other deviations, such as deformations of the second body during operation, can be compensated by a possible displacement of the linear displacement sensor transversely to the direction of movement. In other words, the linear displacement sensor is driven by the second body only in the direction of movement and is decoupled from the second body transversely to the direction of movement, so that it can move freely to a certain extent. The displacement of the linear displacement sensor transversely to the direction of movement is preferably based only on the guidance of the linear displacement sensor on the scanning tape. Therefore, the distance between the linear displacement sensor and the scanning tape can be reliably maintained.

[0010] Preferably, the linear displacement sensor is connected to the second body via a plug-in connection device, wherein the plug-in direction of the plug-in connection device is oriented transversely to the direction of movement. Thus, it is possible to drive the linear displacement sensor in the direction of movement and to displace the linear displacement sensor transversely to the direction of movement in a simple manner. In a preferred design, the plug-in connection device has a protrusion inserted into a corresponding opening, wherein the protrusion is fixed in the direction of movement in the opening and is movably supported in a first transverse direction oriented transversely to the direction of movement, so that the protrusion is abutted against the peripheral surface of the opening on both sides in the direction of movement and slides on the peripheral surface of the opening. Additionally or alternatively, the protrusion is preferably movably supported in a second transverse direction oriented transversely to the direction of movement, so that there is a gap between the peripheral surface of the protrusion and the opening in the second transverse direction. Preferably, the protrusion is arranged on the linear displacement sensor, and the opening is arranged on the second body. Alternatively, the protrusion can also be arranged on the second body, and the opening can be arranged on the linear displacement sensor.

[0011] By making the protrusions bear against the circumference of the opening on both sides, the movement of the second body can be directly transmitted to the linear displacement sensor. By means of the protrusions which are slidably supported on the circumference of the opening, the linear displacement sensor can be moved relative to the second body in a first lateral direction transverse to the direction of movement, wherein the protrusions are only slidably supported on the section of the circumference of the opening which acts in the direction of movement. By means of the gap between the protrusions and the circumference of the opening, the linear displacement sensor can be moved relative to the second body in a second lateral direction. Viewed in the vehicle coordinate system, assuming that the direction of movement is oriented in the longitudinal direction of the vehicle, the linear displacement sensor can be moved by means of the slidably supported in the vertical direction of the vehicle corresponding to the first lateral direction, and by means of the gap between the circumference of the opening and the protrusions, in the lateral direction of the vehicle corresponding to the second lateral direction, in order to compensate for any deviations which occur. The lateral direction can also have other orientations. It is only important that the lateral direction is oriented transversely to the direction of movement.

[0012] Preferably, a sleeve-shaped driving element is arranged on the second body or the linear displacement sensor and is connected to the second body or the linear displacement sensor in a form-fitting manner, wherein the driving element has the opening or forms the protrusion. Depending on whether the protrusion is arranged on the second body or on the linear displacement sensor, or whether the opening is arranged on the second body or on the linear displacement sensor, the sleeve-shaped driving element can be fixed on the second body or on the linear displacement sensor and have an opening or form a protrusion. The driving element must be connected to the second body or the linear displacement sensor in a form-fitting manner in the direction of movement. This can be implemented in particular in such a way that the second body or the linear displacement sensor has a receiving opening into which the sleeve-shaped driving element is inserted.

[0013] In a preferred design, the sleeve-shaped driving element has a radial protrusion and a locking element, wherein the sleeve-shaped driving element is arranged in the receiving opening of the second body and is fixed in the plugging direction of the driving element, that is, the longitudinal direction, by the radial protrusion and the locking element. The radial protrusion and the locking element are preferably arranged on the outer side of the driving element. The radial protrusion and the locking element are arranged spaced apart from each other in the longitudinal direction of the driving element, and the spacing is equivalent to the wall thickness of the second body or the linear displacement sensor in the area of ​​the receiving opening. The locking element is designed to be elastic.

[0014] When the driver element is assembled, the driver element can be inserted into the receiving opening until the radial projection abuts against the second body or the linear displacement sensor, in which position the latching element has been pushed back during the insertion movement and the latching element is snapped back in. In this position, the driver element abuts with the radial projection in the longitudinal direction against a first abutment surface of the second body or the linear displacement sensor and with the latching element against a second abutment surface of the second body or the linear displacement sensor facing away from the first abutment surface. The driver element is thus fixed in two directions relative to the longitudinal direction of the driver element.

[0015] Preferably, the linear displacement sensor is guided on the scanning tape in the direction of movement. For this purpose, the linear displacement sensor preferably has two guide elements, which engage the scanning tape from behind. Since the linear displacement sensor is movably supported on the second body transversely to the direction of movement and is guided on the scanning tape in the direction of movement, i.e., displacement of the linear displacement sensor relative to the scanning tape due to the guidance is prevented transversely to the direction of movement, a predefined position of the linear displacement sensor relative to the scanning tape can be reliably maintained, and thus distortion of the sensor signal of the linear displacement sensor due to displacement of the linear displacement sensor relative to the scanning tape can be reliably avoided.

[0016] Preferably, each guide element has an inclined guide surface that tapers toward one another and rests against an inclined counter-guide surface of the scanning tape. This provides a dovetail-like guide of the linear displacement sensor on the scanning tape. This makes it possible to provide an accurate positioning of the linear displacement sensor relative to the scanning tape transversely to the direction of movement in a simple manner.

[0017] In a preferred embodiment, the scanning strip is chamfered at the end side in order to facilitate the introduction of the scanning strip into the space between the two guide surfaces.

[0018] Preferably, the linear displacement sensor has a housing having an upper part and a lower part, wherein a printed circuit board is engaged with the lower part and the upper part is engaged with the printed circuit board. For this purpose, the upper part has one or more locking elements, which are designed as elastic locking hooks and engage with the printed circuit board from behind in the assembled state. In the final assembled state, the locking element is prevented from loosening by the lower part, in that a part of the lower part rests on the outer side of the locking element. The lower part also includes one or more locking elements, which are designed as elastic locking hooks. In the assembled state, the locking element of the lower part engages with the printed circuit board from behind and is thus also connected to the printed circuit board in a form-fitting manner. Therefore, the printed circuit board forms the base of the linear displacement sensor, wherein the upper part and the lower part are fixed to the printed circuit board. In this way, the linear displacement sensor can be easily assembled and has a simple structure.

[0019] In a preferred design, the upper part has a plug, wherein electrical, elastic contact elements are arranged on the upper part for contacting with mating contacts of the printed circuit board respectively. Since the upper part is connected to the printed circuit board by a latching connection, and the electrical connection between the plug and the printed circuit board is achieved by the spring contact elements, electrical connection can be easily achieved and the assembly of the linear displacement sensor can be simplified. Therefore, the electrical contact between the contact elements of the plug and the mating contact elements of the printed circuit board is automatically achieved by assembling the upper part.

[0020] Preferably, the printed circuit board is positioned relative to the upper part by means of a plug connection in order to ensure a reliable electrical coupling between the spring contact element and the mating contact of the printed circuit board. The plug connection is provided by at least one pin arranged on the upper part, wherein the pin engages in an opening of the printed circuit board corresponding thereto. Alternatively, the pin can also be arranged on the printed circuit board and the opening can be arranged on the upper part.

[0021] Preferably, the linear displacement sensor is an inductive sensor. Alternatively, the linear displacement sensor can also be a magnetic field sensor, an optical sensor or a sensor according to other working principles. This inductive sensor has in particular a cursor band forming a scanning band, which has a plurality of cursor pads (Cursorpads) and non-coupling sections respectively arranged between the cursor pads. The cursor pads are preferably arranged in two rows arranged parallel to each other, wherein the spacing between the cursor pads of the first row and the spacing between the cursor pads of the second row are different from each other. The cursor pads are used as inductive coupling areas of the stator of the linear displacement sensor, wherein a stator is provided for each row of cursor pads. These stators respectively have an excitation coil and a sensor coil group, which are arranged on or in a corresponding stator currently provided on a printed circuit board in a manner known to those skilled in the art. The position of the second body relative to the first body is determined by the sensor signal of the linear displacement sensor using the known vernier principle.

[0022] In a preferred embodiment, the first body is a fixed vehicle seat rail and the second body is a vehicle seat companion rail connected to the vehicle seat and movable with the vehicle seat. Thus, the linear displacement sensor and the scanning strip are used to determine the position of the adjustable vehicle seat. Vehicle seat rails and vehicle seat companion rails are usually subject to completely different loads and necessarily have certain manufacturing and assembly tolerances due to their construction. Therefore, the structure of the vehicle system component described in the above paragraph is particularly advantageous for use in a vehicle seat guide system. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The present invention is described in detail below with the aid of the accompanying drawings. In the accompanying drawings:

[0024] Figure 1 A schematic longitudinal section diagram of a vehicle system assembly according to the present invention is shown;

[0025] Figure 2 Show Figure 1 A schematic cross-sectional view of a vehicle system component in FIG. 1 ; and

[0026] Figure 3 Show Figure 1 and Figure 2 Schematic top view of a scan strip of vehicle system components. DETAILED DESCRIPTION

[0027] Figure 1 and Figure 2 A vehicle system component 10 is shown, which comprises a first body 12 and a second body 14. For example, the first body 12 is a fixed vehicle seat guide which is fixed to the motor vehicle body in white, while the second body 14 is a vehicle seat rail which is connected to the vehicle seat and can be moved together with the vehicle seat. The vehicle seat rail engages in the vehicle seat guide, so that the vehicle seat rail and thus the vehicle seat are guided by the vehicle seat guide during adjustment, wherein the adjustment is carried out in particular by means of an electric drive unit.

[0028] In order to detect the position of the second body 14 relative to the first body 12, a scanning tape 20 is arranged on the first body 12, and a linear displacement sensor 30 is arranged on the second body 14, wherein the scanning tape 20 cooperates with the linear displacement sensor 30 or is scanned by the linear displacement sensor 30 designed as an inductive sensor.

[0029] like Figure 3 As shown, the scanning belt 20 has two rows 24 and 26 extending parallel to each other, and the rows have a plurality of scanning elements 22. The scanning elements 22 of the two rows 24 and 26 are arranged offset from each other, that is, the distances between the scanning elements 22 of the two rows 24 and 26 are different from each other. When the vernier principle is applied, the position of the second body 14 relative to the first body 12, that is, the position of the vehicle seat, can be reliably and accurately determined by the linear displacement sensor 30.

[0030] The linear displacement sensor 30 has a housing 31 and a printed circuit board 36, wherein the housing 31 is made in particular of plastic. The printed circuit board 36 is arranged inside the housing 31 and has the corresponding components 38 required for detecting the scanning strip 20 and determining the position of the second body 14 relative to the first body 12. The housing 31 comprises an upper part 32 and a lower part 34. The linear displacement sensor 30 is based in particular on the inductive measuring principle. Such a linear displacement sensor based on the inductive measuring principle is, for example, a so-called CIPOS sensor from the company HELLA.

[0031] The upper part 32 is connected to the printed circuit board 36 in a form-fitting manner via a latching connection 40 in that the upper part 32 has a plurality of latching elements 401, 402 that engage from behind the printed circuit board 36. In the assembled state, the lower part 34 is partially arranged on the latching elements 401, 402 that engage from behind the printed circuit board 36, so that the latching elements 401, 402 prevent the latching connection 40 from being released by the lower part 34. For this purpose, the upper part 32 is mounted on the printed circuit board 36 before the lower part 34 is mounted on the printed circuit board 36.

[0032] The upper part 32 comprises a plug 44 having a plurality of contact elements 46, through which the linear displacement sensor 30 can be connected to the evaluation unit 90. The contact element 46 is designed as a spring contact element and has an elastic section extending into the inner cavity of the housing 31, wherein the elastic section is electrically coupled to the mating contact 48 of the printed circuit board 36 in the assembled state of the linear displacement sensor 30. By designing the contact element 46 as a spring contact element, the electrical contact between the contact element 46 and the mating contact 48 can be established only by connecting or locking the upper part 32 to the printed circuit board 36, wherein when the upper part 32 is assembled on the printed circuit board 36, the elastic section of the contact element 46 is deformed and thus prestressed, so that the contact element 46 is pressed onto the mating contact 48. In order to precisely orient the upper part 32 in all directions relative to the printed circuit board 36 and thus provide a reliable coupling between the contact element 46 and the mating contact 48, the upper part 32 also has a plurality of pins 821, 822 protruding in the direction of the printed circuit board 36, which engage in respective openings 841, 842 of the printed circuit board 36. The pins 821, 822 and the openings 841, 842 form the plug connection 80.

[0033] The lower part 34 is also connected to the printed circuit board 36 in a form-fitting manner via a latching connection 42. For this purpose, the lower part 34 has a plurality of latching elements 421, 422 that engage the printed circuit board 36 from behind. Here, the printed circuit board 36 rests on the shoulder 43 of the lower part 34 and engages from behind on the side opposite to the shoulder 43 via the latching elements 421, 422. The lower part 34 is designed in a frame-like manner, so that openings are provided in the upper area where the upper part 32 is arranged and in the lower area facing the scanning tape 20. Through the openings in the lower area, the scanning tape 20 can be scanned by the corresponding components arranged on the printed circuit board 36.

[0034] Furthermore, as viewed in the vehicle transverse direction Q, i.e. in the second transverse direction Q2, the lower part 34 has guide elements 70, 72 on both sides, which are used to guide the linear displacement sensor 30 on the scanning element 20 during the adjustment of the second body 14 relative to the first body 12 in the direction of movement B. The guide elements 70, 72 each have an inclined guide surface 71, 73 that tapers toward one another, which abut against a corresponding, inclined counter-guide surface 74, 76 of the scanning tape 20 and slide along the counter-guide surface during the adjustment process. This provides a dovetail-like guide of the linear displacement sensor 30 on the scanning tape 20, wherein the lower part 34 abuts with the other sliding surface 45 on the side of the scanning tape 20 facing away from the first body 12 and slides along this side during the adjustment process. The dovetail-like guide of the linear displacement sensor 30 is preferably at least slightly prestressed in order to ensure a permanent contact of the lower part 34 on the scanning tape 20.

[0035] The problem when measuring positions with the aid of the linear displacement sensor 30 is that displacements of the linear displacement sensor 30 relative to the scanning tape 20 transversely to the direction of movement B, i.e. in the transverse directions Q1, Q2 or in the vehicle vertical direction H and in the vehicle transverse direction Q with reference to the vehicle coordinate system when the direction of movement B is oriented in the vehicle longitudinal direction L, lead to distortions in the sensor signal of the linear displacement sensor 30. Furthermore, it is required that the air gap LS between the linear displacement sensor 30 and the scanning tape 20 is as small as possible and is the same in every position.

[0036] In order to avoid distortion of the sensor signal of the linear displacement sensor 30, the linear displacement sensor 30 is supported on the second body 14 transversely to the movement direction B, that is, movably in two transverse directions Q1, Q2, wherein the linear displacement sensor 30 is fixedly supported on the second body 14 in the movement direction B. For this purpose, the linear displacement sensor 30 and the second body 14 are connected to each other via a plug connection 50, wherein the plug-in direction is oriented in the first transverse direction Q1 or in the vehicle vertical direction H.

[0037] The plug connection 50 consists of a projection 52 formed on the upper part 32 of the housing 31 and an opening 56 having a circumferential surface 58, wherein the projection 52 engages in the opening 56. In order to provide the opening 56, a sleeve-shaped entrainment element 54 is arranged on the second body 14, which defines the opening 56 by an inner circumferential surface, so that the inner circumferential surface of the entrainment element 54 forms the circumferential surface 58 of the opening 56.

[0038] The sleeve-shaped driver element 54 is connected to the second body 14 in a form-locking manner. For this purpose, the second body 14 has a receiving opening 64, into which the driver element 54 is inserted. As a result, the driver element 54 is connected to the second body 14 in a form-locking manner in the direction of movement B and in the second transverse direction Q2. The driver element 54 is fixed to the second body 14 in the first transverse direction Q1, i.e., in the vehicle vertical direction H in the vehicle coordinate system, on the one hand by means of radial projections 60 and on the other hand by means of a latching connection, wherein the driver element 54 has an elastic latching element 62. When the driver element 54 is mounted on the second body 14, the driver element 54 is inserted through the receiving opening 64 until the radial projections 60 abut against the second body 14 in the longitudinal direction of the driver element 54 and the positioning element 62 has been pressed. When the driver element 54 is pushed through the receiving opening 64, when the latching element 62 is no longer radially loaded by the second body 14 due to the follow-up movement of the driver element 54, the latching element 62 moves back and snaps back into place. In the final assembly state of the driving element 54, the driving element rests on two opposite sides of the second body 14 in the longitudinal direction, that is, it rests on two opposite sides of the second body through the radial protrusion 60 and the locking element 62, thereby fixing the driving element 54 on the second body 14 in the vertical direction H of the vehicle.

[0039] In order to provide a driving function in the movement direction B, i.e., the vehicle longitudinal direction L, and to provide free movement in the transverse directions Q1, Q2, i.e., the vehicle vertical direction H and the vehicle transverse direction Q, the protrusion 52 is directly in contact with the peripheral surface 58 on both sides in the movement direction B, slides along the peripheral surface 58 in the vehicle vertical direction H, and is arranged to be spaced apart from the peripheral surface 58 by a gap S. Figure 1 FIG. 5 shows that the circumferential surface of the projection 52 is in contact with the circumferential surface 58 of the opening 56. Figure 2 , the gap S between the circumference of the projection 52 and the circumference 58 is shown. Thus, the linear displacement sensor 30 is supported or guided transversely to the direction of movement B, ie in both transverse directions Q1, Q2, only by the scanning belt 20, ie by the guide elements 70, 72 resting on the scanning belt 20.

[0040] By means of this design of the vehicle system component 10, the linear displacement sensor 30 can be moved together with the second body 14 in the direction of movement, i.e. in the longitudinal direction of the scanning strip 20 and in the vehicle longitudinal direction L, wherein a predefined position of the linear displacement sensor 30 relative to the scanning strip 20 can be maintained reliably and in particular independently of manufacturing tolerances and other deviations, since in particular deviations that inevitably occur transversely to the direction of movement B can be compensated. In this way, the risk of distortion of the sensor signal of the linear displacement sensor 30 can be reduced. Reference numerals list
