The present disclosure relates to a device for setting a rotational movement or pivoting movement of a control element for a vehicle and a method for adjusting a rotational movement or pivoting movement of a control element for a vehicle.
A so-called latching device can comprise, for example, a locking pin, a locking ball, a latching roller or the like. Such a latching device can be used in the automotive or vehicle sector in conjunction with electrical switching devices, for example, an automatic shift transmission, or for guidance and haptic position feedback of a rotary switch, shift lever or selector lever. DE 10 2007 038 547 A1 discloses a rotary switch with latching.
Against this background, the present disclosure provides an improved device for setting a rotational movement or pivoting movement of a control element for a vehicle and an improved method for adjusting a rotational movement or pivoting movement of a control element for a vehicle according to the main claims. Advantageous embodiments are included in the sub-claims and subsequent description.
According to embodiments of the present disclosure, it is especially possible to provide a device for locking, or a latching device for a control element of a vehicle, wherein a latching element can be rolled along a latching contour. At the same time, the latching element can be arranged to be swivel-mounted in a power transmitting carrier device. The carrier device or power transmitting device can be designed to move the latching element in a rotational manner along the latching contour, when a control element, with which the device can be connected, is activated.
Embodiments of the present disclosure have the advantage that wear and tear can be reduced when, for example, the latching element can roll along the latching contour instead of grinding or slipping on the latching contour. In addition to reduced wear and tear on the latching element and latching contour, it is also possible to improve haptics when activating or operating the control element. Furthermore, it is possible to reduce the number of components of the device and thus shorten the tolerance chain.
A device for setting a rotational movement or pivoting movement of a control element for a vehicle comprises a curved latching contour for defining at least a shift position of the control element, a latching element for engaging in the latching contour and a power transmitting device, with which the control element can be mechanically connected, in order to absorb mechanical forces exerted on the control element during the rotational movement or pivoting movement and transmitting said forces to the latching element, wherein the latching element can be arranged to be swivel-mounted on the power transmitting device, wherein due to the operating force the latching element can be moved in rolling fashion along the latching contour.
The vehicle can involve a motor vehicle, especially a vehicle used for road transport, such as a passenger car or truck. Alternatively, the vehicle can involve, for example, a rail vehicle or an aircraft. The device can be used for adjusting a rotational movement or pivoting movement of a control element of a machine, for example, a vehicle. The device can involve a piece of equipment or part of an equipment of the vehicle. The device can be denoted as a latching device. For example, the control element can be used to select a speed level of an automatic transmission of the vehicle. In particular, the control element can be operated manually by a driver of the vehicle, to adjust different speed levels or gears of the automatic transmission. The control element can also be designed as a joint control element to perform different vehicle functions. In particular, the control element can involve a rotary knob or the like. As a result, the device together with the control element can represent a rotary switch or the like. For example, the rotational movement or pivoting movement of the control element can be performed between at least two shift positions or positions, and additionally or alternatively, between a rest position and at least a deflection position. The latching contour can be arranged, shaped, and additionally or alternatively, designed to guide the latching element, and additionally or alternatively, enable a resistance or a sensor, in particular haptic feedback with respect to a rotational movement or pivoting movement or shift position of the control element. A section of the latching element can be engaged with a section of the latching contour and, because of the operating force, moved in rotational manner along the latching contour. At the same time, said engagement can take place in a frictional and form-fitting manner between the section of the latching element and the section of the latching contour. The power transmitting device can be designed in such a way that it can be connected with a shifting device to produce control signals, depending on the rotational movement or pivoting movement of the control element. The power transmitting device can be mechanically rigidly connected with the control element.
According to one embodiment, the latching element can comprise a centrally arranged bearing segment for supporting the power transmitting device and a peripherally arranged engaging portion for engaging in the latching contour. The bearing segment can have at least one bearing pin for reception in the power transmitting device. In a rotational movement in relation to the power transmitting device, a rotational axis of the latching element can extend through the bearing segment. At the same time, the rotational axis can represent a symmetrical axis of the latching element. The bearing segment can be surrounded at least partially by the engaging portion. Such an embodiment has the advantage that haptics, as well as ease of operation can be improved and imbalances can be minimized.
The bearing section of the latching element can be formed from a hard material with a first elasticity, wherein the engaging portion of the latching element is formed from a soft material with a second elasticity. The second elasticity of the soft material can be greater than the first elasticity of the hard material. For example, such a latching element can consist of or be formed as a one-piece or two-piece component by means of two-component-injection molding process or the like. Such an embodiment has the advantage of reduced noise when operated. The use of the soft material or a soft component can be utilized to generate force, and the use of the soft material can also eliminate the need for compression springs or the like.
In particular, the latching element can comprise at least three projections for engaging in the latching contour. The projections can be produced in the form of legs, arms, noses, or the like. For example, the latching element can be designed to have three, four, five or more legs. The projections can extend radially from a center of the latching element. When the latching element is rotated along the latching contour, at least one projection can be engaged with the latching contour, wherein at least one further projection can be disengaged from the latching contour. Such an embodiment has the advantage of improving the haptics, as well as generating different forces and/or positioning angles for the control element, depending on the number of projections.
According to one embodiment, the latching contour can have a contact section, which is designed to enable an engagement of the latching element. To this end, at least the contact section of the latching contour can be formed from a soft material with an elasticity that is greater than the elasticity of a material of the power transmitting device. Such an embodiment has the advantage that noises generated during operation can be better absorbed when using a soft material or soft component for the latching contour. In addition, the soft material can be used for generating force during an operation and thus eliminate compression springs.
The power transmitting device can also comprise an elastic material, which can be designed to preload the latching element in abutment against the latching contour. In this connection, the power transmitting device can have a first section and a second section, wherein the control element can be mechanically coupled with the first section and the latching element can be arranged to be swivel-mounted with the second section. At the same time, the elastic means can be arranged between the first section and the second section to preload the second section in relation to the first section. Such an embodiment has the advantage that the haptics can be improved when operating the control element and enhance the positional accuracy of shift positions of the device.
For example, the latching contour can have a circular design. To this end, a contact section of the latching contour, which can be designed to enable an engagement of the latching element, can be arranged in radially inward direction. Such an embodiment has the advantage that the device can be shaped in a space-saving manner and ensure that the latching element is guided reliably in the latching contour.
Furthermore, the power transmitting device can have a first rotational axis, wherein the latching element can have a second rotational axis. To this end, the first rotational axis and the second rotational axis can be arranged in parallel manner to each other. Because of the operating force, the power transmitting device and the latching element can be designed to rotate relative to each other in opposite direction about the rotational axes. In particular, the power transmitting device and the latching element can have a mutual rotation level or parallel rotation levels. Such an embodiment has the advantage of allowing for an especially space-saving embodiment of the device. Furthermore, the control element is easy to operate, but also exact. It is also possible to improve the haptics when using the control element.
A method for adjusting a rotational movement or pivoting movement of a control element for a vehicle comprises a step in which the operating force is absorbed from the control element by the power transmitting device and a step in which the operating force is transmitted by the power transmitting device to the latching element, wherein the method can be performed in conjunction with an embodiment of the above-mentioned device.
The method can be advantageously performed in conjunction with or by using an embodiment of the above-mentioned adjusting device to adjust a rotational movement or pivoting movement of a control element for a vehicle.
A shifting device, especially for shifting an automatic transmission of a vehicle, comprises a control element and an embodiment of the above-mentioned device for setting a rotational movement or pivoting movement of the control element, wherein the control element is, or can be, connected with the power transmitting device of the adjusting device. In connection with the shifting device, an embodiment of the above-mentioned adjusting device can be advantageously used or utilized to adjust a rotational movement or pivoting movement of the control element. When the device is assembled, the latching element of the device can be arranged in abutment against the latching contour. Furthermore, the device can have a carrier device, on which the latching contour, the power transmitting device and the latching element can be arranged.
Subsequently, the disclosure is described in more detail in an exemplary manner by means of the enclosed drawings. It is shown:
