Description

Switching lever for actuating an electrical contact

Technical Field

The invention relates to a switching lever for actuating an electrical contact, in particular for a display device.

Background

For example, the driver of the vehicle is distracted from the phenomenon on the road by external influences, such as disturbing noise of vibrations or impacts. These must therefore be minimized in each mechanical element at the vehicle, and therefore also in the shift lever or the pushbutton.

Disclosure of Invention

The invention relates to a switching lever, in particular for a display device, for actuating an electrical contact by moving the switching lever in a guide direction, wherein the switching lever is arranged in a guide in a housing. The switching lever has at least one first elastic element: so that the elastic force of the first elastic element acts between the switch lever and the housing perpendicular to the guiding direction.

The advantage of the invention lies in the bridging of the distance between the electrical contact and the surface of the display device or in the reliable transmission of force between the switching lever and the electrical contact. The actuation, for example pressing, of the switching lever or, for example, of a cover connected to the switching lever by a user or observer thus leads to the actuation of the electrical contacts. For example, a reset of the display device can be operated by manipulating the electrical contacts. Furthermore, the axis for manipulating the electrical contact, hereinafter the pressing direction in which the observer presses the switch lever, does not coincide with the guiding direction of the switch lever in which the switch lever is moved. In this way, an angle is produced between the direction for actuating the electrical contact and the guiding direction of the switching lever, which angle can be spanned by the switching lever according to the invention.

The use of at least one spring element at the switching lever, in which the spring force of the spring element between the switching lever and the housing acts perpendicular to the guide direction, has the advantage that noise, which is generated, for example, by external influences, such as, for example, a jostling, vibration or rattling of the switching lever, is reduced or eliminated. These noises can, for example, distract the driver from the current phenomenon on the road, so that reducing these noises leads to more safety in road traffic. An additional advantage of the elastic element of the switching lever is a more reliable guidance of the switching lever in the housing when the switching lever is actuated. The spring element of the switching lever serves as a lateral guide element for the switching lever. Also, friction between the case and the switch lever can be reduced by using the elastic member.

In a further advantageous embodiment, the switching lever has at least one further second spring element: so that the elastic force of the second elastic element acts between the switch lever and the housing perpendicularly to the guiding direction. The use of a further second elastic element contributes positively to the reduction or elimination of noise. The switching lever can also be reliably guided in a guide in the housing, so that it is ensured that the electrical contacts are contacted.

Preferably, the switching lever has at least two elastic elements: so that the elastic forces of two elastic elements between the switch lever and the housing act perpendicular to the guiding direction and are arranged on opposite sides of the switch lever with respect to the guiding direction. This makes it possible to reduce noise on the one hand and to ensure the guidance of the switching lever in the housing on the other hand. In this way, it can be ensured that the switching lever does not slip in the display device and can be held in the position provided for this purpose or guided in a predefined path thereof. Also, friction between the case and the switch lever can be reduced by using the elastic member. The spring force of the individual spring elements can be easily adapted to the conditions in this configuration.

A further advantageous embodiment is obtained by: i.e. at least one elastic element is arranged as an integrated elastic element at the switching lever. The position of the switch lever relative to the housing can thereby be kept stable. A further advantage of the one-piece design of the switching lever and of the at least one spring element is the simple and rapid production and assembly. Such a switching lever can be composed of a single body without having to engage several individual parts with one another in many individual steps, which individual parts have to meet high requirements as to the position and orientation of the individual parts with respect to one another. As an additional measure, only one component, namely the switching lever with the spring element designed in one piece, has to be oriented and fixed when positioning the switching lever in the housing, so that the expenditure is saved.

In an exemplary embodiment, the at least one spring element is prestressed in the assembled state. The spring element of the switching lever is therefore pressed against a support provided for this purpose at the housing. The preloaded spring element ensures that the switching lever does not slip in the display device and can be held in the position provided for this purpose or guided in a predetermined path thereof. This also contributes positively to the reduction of noise and vibrations.

In a further development, the switching lever has at least one further third spring element: so that the switching lever is once again returned into the initial position after actuation. It is thereby ensured that the switching lever is subsequently returned into its initial position after actuation, so that the switching lever can be actuated again if a further reset of the display device is necessary. Preferably, the spring element has an S-shape, wherein the spring force of this spring element acts between the switching lever and the housing in the direction of the guide direction. This also enables tactile feedback to be given to the user, so that the user feels a resistance when actuating the shift lever. This feedback contributes in a positive way to the ergonomics of the switching lever. The spring force of the spring element can be simply adapted to the condition in this configuration.

A further advantageous embodiment is characterized in that the switching lever has at least one further spring element, wherein the further spring element rests on the housing. The switching lever can thereby be damped at the housing, so that it is prevented that the switching lever and the housing or other components strike together and thereby generate noise. A spacing can thereby preferably be maintained between the housing and the switching lever. The use of a further spring element thus positively contributes to the reduction or elimination of noise. Also, friction between the case and the switch lever can be reduced by using the elastic member. The spring force of the further spring element between the switching lever and the housing acts perpendicular to the guide direction of the switching lever and/or perpendicular to the guide direction of the spring force of the first spring element. The spring force of the individual spring elements can be easily adapted to the conditions in this configuration.

In an exemplary embodiment, the switching lever has at least one notch and/or a fastening element: so that the cover portion can be arranged at the switch lever. The cover is mounted at the switching lever in the direction of the user or viewer (and is therefore visible at the display device or in the field of view of the viewer) in such a way that: so that the observer can press the cover for manipulating the switching lever and thus the electrical contact. The cover part can be constructed, for example, in one piece with the switching lever or be connected to the switching lever as a separate component, for example, via a mechanical connection, for example via a hook, a clip, a rivet or a screw. This makes it possible to realize variants which are cost-effective and/or optically/visually effective. Different materials can be realized with the two-part embodiment. For example, cost-effective materials can be used for the non-visible part of the switching lever and materials that contribute optically to the viewer can be used for the visible cover. Advantageously, a cover at the switching lever is used for actuating the switching lever.

In one embodiment, the switching lever can also have at least one tappet, wherein the tappet contacts the electrical contact when the switching lever is actuated. The tappet can be connected to the switch lever in a single piece, wherein the tappet is mounted at the switch lever in a guide direction such that an end of the tappet that is not connected to the switch lever contacts the electrical contact. When the switch lever is actuated or pressed, the tappet is displaced in the direction of the electrical contact, contacts the electrical contact and thus triggers an operation, for example a reset of the display device.

In an exemplary embodiment, the switching lever has a reinforced rib. The reinforcing rib gives the switching lever a stable shape, so that the switching lever is not or not strongly deformed, for example by externally acting forces, such as vibrations, jolts or by actuating or pressing the switching lever.

A further embodiment can have a housing which is designed to accommodate at least one switching lever. Preferably, the housing has at least one guide for guiding at least one spring element of the switching lever, wherein the spring element of the switching lever is slidingly supported at the guide of the housing. The housing preferably has at least one guide for guiding the switching lever in the housing. The guide at the housing for the switching lever and for the spring element at the switching lever ensures that the switching lever does not slip within the display device and can be held in the position provided for this purpose or guided in a predefined path thereof.

The switching lever is preferably arranged on a housing in a display device, wherein the display device can be mounted, for example, on a dashboard of a vehicle.

Detailed Description

Fig. 1 shows an exemplary embodiment of a display device 20. The display device 20 preferably comprises a housing 22, a plate 24 and at least one first digital sheet 26, which for example shows the speed and/or the rotational speed of, for example, a vehicle. The display device 20 is preferably arranged or incorporated in a dashboard or instrument panel of a vehicle. Preferably, said display means 20 have a further second digital sheet 27 (which displays, for example, the speed and/or the rotation speed) and at least one further third digital sheet 28, smaller with respect to said first digital sheet 26, which displays, for example, the horological time, the temperature and/or the state of filling of the tank of the vehicle. In this exemplary embodiment, the display device 20 has a further fourth digital sheet 29, smaller with respect to the first digital sheet 26, which displays, for example, the clock time, the temperature and/or the state of filling of the tank of the vehicle. The first, second, third and fourth

digital sheets

26, 27, 28, 29 are arranged in the housing 22. A plate 24, preferably comprised of transparent glass or plastic, is disposed on the housing 22, wherein the first, second, third and fourth

digital sheets

26, 27, 28, 29 are visible to a driver or observer of the display device 20 through the plate 24. Alternatively, a digital display, for example an LCD, can also be used in the display device 20 in addition to or instead of the

digital disks

26, 27, 28, 29, which display additional information, for example navigation instructions. If the

number sheet

26, 27, 28, 29 is replaced by the display, the information is displayed on the display instead on the number sheet.

At a lower end of the display device 20, a switch lever 30 (e.g., a key or an operating element) and a hood 32 disposed at the switch lever 30 are disposed. The switching lever 30 is arranged in this embodiment at the lower end of the display device 20 (viewed in the direction of the line of sight of the observer or driver of the vehicle), for example to the right of the axis of symmetry 34 of the display device 20. If the display device 20 is installed in a vehicle, for example, only the cover 32 is visible to the driver or observer, wherein the switching lever 30 is covered by a partition, not shown here. In the event of an error of the display device 20, for example in the case of an erroneous display of the

digital disks

26, 27, 28, 29 or of information on a display, the driver can press the hood 32, so that the switch lever 30 contacts the electrical contacts. Thus, a reset of the display device 20 is triggered, wherein the display device 20 is first switched off and then restarted.

The switching lever 30 can be constructed, for example, from plastic, for example Polycarbonate (PC), Acrylonitrile Butadiene Styrene (ABS), polyethylene terephthalate (PBT), PC-ABS and/or metal, for example steel, magnesium or aluminum die castings. Since the cover part 32 is visible to the observer, this cover part is preferably made of an optically/visually effective material, for example a plastic, such as Polycarbonate (PC), Acrylonitrile Butadiene Styrene (ABS), polybutylene terephthalate (PBT), PC-ABS and/or a coated plastic with a metal coating (e.g. a chromium-plated plastic) and/or a metal, for example a steel plate, a magnesium die casting or an aluminum die casting. Alternatively, the switching lever 30 and the cover 32 can also be made of the same material in one piece.

Fig. 2 shows an exemplary embodiment of a switching lever 30 with a cover 32. The switch lever 30 is disposed in the case 22 of the display device 20. When the switching lever 30 is actuated or when the observer presses on the hood 32, the switching lever 30 is moved in the guide direction 38. In this embodiment in fig. 2, the switch lever 30 is shown in its original position, and thus in a position in which the switch lever 30 is not pressed by the viewer or user. The switching lever 30 is preferably 30 mm to 65 mm, in particular 55 mm wide, and 60 mm to 120 mm, in particular 84 mm long.

The switching lever 30 has at least one first spring element 40, which is preferably connected in one piece to the switching lever 30 and rests on the first guide 36 of the housing 22. The spring force of the first spring element 40 between the switching lever 30 and the housing 22 or the first guide 36 of the housing 22 acts in this embodiment perpendicular to the guide direction 38 of the switching lever 30. The first guide 36 is arranged on the housing 22 in accordance with this, wherein the first spring element 40 is mounted slidably on the first guide 36, so that the first spring element 40 can move on the first guide 36. For this purpose, the first guide 36 can project as a projection from the housing 22. In this embodiment, the switching lever 30 has a further second spring element 42, which is preferably likewise connected in one piece to the switching lever 30 and rests on a second guide 44 of the housing 22. The spring force of the second spring element 42 between the switching lever 30 and the housing 22 or the second guide 44 of the housing 22 acts in this embodiment perpendicular to the guide direction 38. The second guide 44 is arranged on the housing 22 in accordance therewith, wherein the second spring element 42 is mounted in a sliding manner on the second guide 44. For this purpose, the second guide 44 can project as a projection from the housing 22.

The second elastic element 42 is preferably arranged on the side of the switching lever 30 opposite the first elastic element 40 with respect to the guide direction 38. The distance between the outermost point of the first spring element 40 and the outermost point of the second spring element 42 is preferably 20 mm to 60 mm, in particular 41 mm.

In an exemplary embodiment, the switch lever 30 has at least one further third elastic element 46, wherein the third elastic element 46 returns the switch lever 30 again into the initial or original position in the state without being pressed after the switch lever 30 is actuated or pressed by the observer. For this purpose, the third spring element 46 (which preferably has an S-shape) is arranged at the lower end of the switching lever 30 or on the side which is not visible to the observer and has the cover 32 and rests on the housing 22 or is supported with the end of the S on the housing 22. For fixing the third elastic element 46 at the housing 22, the third elastic element 46 can have a ridge or hook at the end which is not connected to the switch lever 30. The spring force of the third spring element 46 between the switching lever 30 and the housing 22 acts in the guide direction 38 of the switching lever 30 and thus perpendicularly to the spring force of the first spring element 40 and/or the second spring element 42. The thickness of the third spring element 46 can preferably be 0.5 mm to 4 mm, and the length of the third spring element 46 or the direct distance between one end of the third spring element 46 connected to the switching lever 30 and the free end of the other third spring element 46 resting against the housing 22 can be 10 mm to 40 mm, in particular 20 mm. In one embodiment, the spring force or the restoring force can be, for example, 1N to 10N.

When the switching lever 30 is pressed, the third elastic element 46 is deformed, wherein, for example, the S-shape of the third elastic element 46 is pressed and thus tensioned. For this purpose, the third spring element 46 is supported on the housing 22. If the switching lever 30 is relieved of load again, or the observer withdraws his pressure on the switching lever 30, the third elastic element 46 presses the switching lever 30 back into the original position, so that the tension of the third elastic element 46 is reduced. Through this, the observer also receives tactile feedback from the switching lever 30, for example.

In a further development, the switching lever 30 has at least one further fourth spring element 54, which rests against the housing 22. Preferably, the switching lever 30 also has a fifth spring element 56, which likewise rests on the housing 22. Said fourth and/or fifth elastic element 54,

56 is formed on the switching lever 30, for example, in the shape of a horseshoe, wherein the rounded free end rests on the housing 22. For example, hemispherical projections can be formed at the rounded free ends of the fourth and/or

fifth spring elements

54, 56, which contact the surface of the housing 22 at the location of the largest projection and thus guide the switching lever 30.

The

spring elements

40, 42, 46, 54, 56 of the switching lever 30 are preferably connected in one piece to the switching lever 30 and are therefore produced together with the switching lever 30. Alternatively, the

spring elements

40, 42, 46, 54, 56 can also be mounted later on the switching lever 30, for example by gluing, screwing or welding.

In the assembled state of the switching lever 30, i.e., after the switching lever 30 has been assembled into the housing 22, the first, second, fourth and

fifth spring elements

40, 42, 54, 56 are prestressed. That is to say, the switching lever 30 or the spring element is pressed in the pretensioned state against a guide or a support of the housing 22. This ensures that, on the one hand, the switching lever 30 moves in the guide direction 38 during actuation and, on the other hand, no noise is generated by external influences, such as vibrations or impacts during driving of the vehicle, which can distract the driver.

At the upper end of the switch lever 30 (thus on the opposite side of the third elastic element 46 and visible to the observer), a hood 32 is arranged at the switch lever 30. For this purpose, the switching lever 30 has at least one first slot 58 for fastening the cover 32 at the switching lever 30. The switching lever 30 has a further second notch 60, a third notch 62 and/or a fourth notch 64 in such a way that: so that the hood 32 can be arranged at the switch lever 30. For this purpose, the cover 32 can have, for example, a first pin 66 and/or a second pin 67, which protrude into the

notches

58, 60, 62, 64 of the shift lever 30 and thus fix the cover 32 to the shift lever 30. To this end, in this exemplary embodiment it is possible to insert the first pin 66 into the first and

second notches

58, 60 and the second pin 67 into the third and

fourth notches

62, 64. Furthermore, the switching lever 30 can have at least one first fastening element 68, for example a hook or a rivet, which projects into the cover 32 and thus fastens it. Preferably, the switching lever 30 has a further second fastening element 69, which likewise projects into the cover 32 and thus fastens this cover.

The observer presses the cover 32 when actuating the switching lever 30, so that the complex formed by the switching lever 30 and the cover 32 is thus moved in the guide direction 38.

The switch lever 30 also has a tappet 70, which is arranged at the lower end of the cover 32 and thus at the opposite end at the switch lever 30 or on a side that is not visible to the observer. The tappet 70 can preferably be formed in one piece with the switching lever 30 and in this embodiment points in the same direction as the spring force of the third spring element 46. When the switching lever 30 is actuated, the tappet 70 or a free end of the tappet 70 that is not connected to the switching lever 30 contacts an electrical contact 82, wherein the electrical contact 82 can be arranged, for example, in the housing 22. If the electrical contact 82 is contacted, a reset is triggered, so that the display device 20 is first switched off and then restarted. A reset should be triggered by the viewer if an error occurs while displaying information on the display device 20 or if information on the display device 20 is presented incorrectly. The reset must be triggered manually or by hand by an observer or user.

The distance between a free end of the first spring element 40 that is not connected to the switch lever 30 and a free end of the tappet 70 that is not connected to the switch lever 30 can be 20 mm to 80 mm, in particular 55 mm. The distance between a free end of the first spring element 40 that is not connected to the switch lever 30 and a free end of the tappet 70 that is not connected to the switch lever 30 can be 20 mm to 80 mm, in particular 41 mm.

In a further development, the switching lever 30 has a reinforcing rib 72, which is arranged integrally on the switching lever 30. The rib 72 reinforces the switch lever 30, so that deformation of the switch lever 30, which can be generated by, for example, an external impact or an excessively strong load, such as vibration, or an excessively strong pressing of the cover portion 32 by the observer, can be kept small. The switch lever 30 can also be designed lighter on the basis of said reinforcing ribs 72, thus saving weight. The ribs 72 can be arranged, for example, at an angle to the guide direction 38 and/or cross each other.

Fig. 2 also depicts a positioning axis 48 of the switching lever 30, an elastic axis 50 of the third elastic element 46, and an actuating axis 52 of the switching lever 30, wherein the

axes

48, 50, 52 are arranged in the longitudinal direction at the switching lever 30 and therefore point in the guide direction 38 of the switching lever 30. The positioning axis 48 of the switching lever 30 is the axis: by means of which the switching lever 30 is positioned in the housing 22, for example, during assembly. The elastic axis 50 of the third elastic element 46 is arranged between the switch lever 30 and the housing 22 in the direction of the elastic force of the third elastic element 46 by means of the third elastic element 46. The actuating axis 52 of the switching lever 30 is arranged via the tappet 70 and indicates the axis: in which the electrical contacts 82 are contacted, which in this embodiment do not have to coincide on one axis, but can be arranged separately at different regions of the switching lever 30.

Fig. 2 also has a housing 22, wherein the housing 22 is designed to accommodate at least one switching lever 30. For this purpose, the housing 22 preferably has at least one first guide 36 for guiding the first spring element 40 and a second guide 44 for guiding the second spring element 42. For this purpose, the first or

second spring element

40, 42 is mounted in a sliding manner on the

respective guide

36, 44 of the housing 22. For this purpose, the first and/or

second guide

36, 44 can project as a projection from the housing 22. Furthermore, the housing 22 has a further third guide 74, which is arranged at the level of the tappet 70 of the switching lever 30 at the housing 22, so that the tappet 70 bears against the third guide 74 and is mounted in a sliding manner thereby. For this purpose, the third guide 74 can project as a projection from the housing 22. The housing 22 also has a fourth guide portion 76 and a fifth guide portion 78, which guide the switching lever 30 during actuation. For this purpose, the switching lever 30 has a third fastening element 80 and a fourth fastening element, for example a pin, wherein the third fastening element 80 is guided in the fourth guide 76 and the fourth fastening element is guided in the fifth guide 78. The third fastening element 80 and the fourth fastening element are arranged on opposite sides of the switching lever 30 with respect to the guide direction 38. In this exemplary embodiment, the third fastening element 80 and the fourth fastening element are arranged at the upper end of the switch lever 30 connected to the hood 32. The height of the third fastening element 80 and/or of the fourth fastening element can be 1 mm to 15 mm, in particular 7 mm, and the thickness of the third fastening element 80 and/or of the fourth fastening element can be 0.5 mm to 7 mm, in particular 2 mm.

For this purpose, the fourth and/or

fifth guide

76, 78 can project as a projection from the housing 22, wherein a recess is left free in order to receive and guide the fastening element 80. The fourth and

fifth guide sections

76, 78 ensure that the switching lever 30 is guided in the direction of the guide direction 38 during actuation. For this purpose, the third and fourth fastening elements 80 project into the

respective guide

76, 78.

Fig. 3 shows an exemplary embodiment of the switching lever arrangement 30. In this embodiment, the switch lever 30 is shown in the pressed position. The switching lever 30 is therefore pressed by the observer, for example, in order to cause a reset, so that the switching lever 30 is moved 1 mm to 4 mm, in particular 2 mm, in the direction of the electrical contact 82. Via this, the tappet 70 of the switching lever 30 contacts an electrical contact 82 in the housing 22, so that an operation, for example a reset, is triggered. The switching lever 30 is moved in the guide direction 38 by means of an elastic element at the switching lever 30 and a guide at the housing 22. The first guide portion 36 and the second guide portion 44 are configured such that: so that the first elastic element 40 is supported in a sliding manner at the first guide 36 and the second elastic element 42 at the second guide 44, and the first or second

elastic element

40, 42 is also supported after the movement of the switching lever 30, in a further manner at the respective guide. To this end, the first and

second guide portions

36, 44 can project as projections from the housing 22.

The third elastic element 46 is deformed in response to the movement of the switching lever 30: so that the S-shape is pressed together. For this purpose, the third spring element 46 is supported on the housing 22. The third spring element 46 or the spring force of the third spring element 46 (wherein the spring force of the third spring element 46 is directed in the same direction as the guiding direction 38 of the switching lever 30) is responsible for: after actuating the switch lever 30, the switch lever 30 is pressed back into its original position again. After the switching lever 30 is pressed back, the third spring element 46 is partially and/or completely relieved of pressure.

The fourth and

fifth guide portions

76, 78 at the housing 22 can be configured such that: so that a movement of the switching lever 30 in the direction of the electrical contact 82 is defined. If the third fastening element 80 abuts against the lower limit of the fourth guide 76 and/or one further fourth fastening element abuts against the lower limit of the second guide 78, the switching lever 30 can no longer be pressed further. This can be designed in such a way: so that the electrical contacts 82, although contacted, are not damaged by too strong a press by the user.

Fig. 4 shows an exemplary embodiment of a cross section of a display device 20 having a housing 22, a plate 24 and having a switch lever 30 with a hood 32. Shown is a cross-sectional view through the switch lever 30 and thus also through the housing 22 and the plate 24 of the display device 20. Furthermore, an electrical contact 82 is shown in cross section, which is fastened, for example, at the housing 22 so as to be invisible to an observer. The switch lever 30 is arranged in the housing 22 such that the tappet 70 of the switch lever 30 can contact the electrical contact 82. The opposite end of the switch lever 30 (opposite the tappet 70) has a hood 32, which is arranged to be visible to the viewer below the plate 24 of the display device 20 at the switch lever 30. If an observer or driver presses on the cover 32 of the switch lever 30, the switch lever 30 moves in the guide direction 38, so that the tappet 70 contacts the electrical contact 82 and thus triggers, for example, a reset of the display device 20.

Also depicted in fig. 4 are a pressing direction 84 in which the observer presses the switching lever 30 or the cover 32 or in which the electrical contacts 82 have to be contacted, and a movement direction or guide direction 38 in which the switching lever 30 is moved during actuation or in which the switching lever 30 is guided. Between the pressing direction 84 and the guide direction 38 is an angle 86, which is preferably between 4 ° and 30 °, in particular 15 °. The design of the shift lever 30 and the arrangement of the shift lever 30 at the housing 22 serve to span this angle 86.
