Abstract
Description
Technical Field
[0001] A first aspect of the present invention relates to a switch module. A second aspect of the present invention relates to a method for assembling a switch module. A third aspect of the present invention relates to a steering rocker arm for a motor vehicle. Background Technology
[0002] like Figure 12 The steering rocker arm a shown is known in the prior art, especially in the production of series vehicles. Figure 12 A perspective view shows a steering rocker arm a designed according to the prior art, wherein a conventional switch b is mounted in a conventional manner. For this purpose, the conventional steering rocker arm a has a switch opening c, into which the conventional switch b is inserted along the assembly direction d. Here, the carrier elements e of the steering rocker arm a are forcefully directed toward each other. The conventional carrier element e and / or the conventional switch b have assembly ramps (not shown) for this purpose. As the assembly ramp of the carrier element e slides on the inside of the switch b and / or the assembly ramp of the switch b slides on the carrier element e, the carrier elements e are forcefully directed toward each other. During the further pushing of the switch b into the steering rocker arm a or through the switch opening c, when the fastening element of the carrier element e (in...) Figure 12 When the carrier element e (not visible in the image) engages with the fastening element socket f of switch b, the stress on the carrier element e is relieved. Due to the conventional assembly ramp, the retaining surface of the steering rocker arm a, such as the retaining surface g of switch b, is particularly small, resulting in only a very small force being required to unintentionally, for example, separate switch b from the rest of the steering rocker arm a. In particular, if switch b is in the form of a rocker switch, a particularly large force will occur at the retaining surface g, which will then cause switch b to unintentionally separate from the steering rocker arm a in interaction with the particularly small retaining surface. This means that the conventional steering rocker arm a is not a particularly stable form.
[0003] Furthermore, in the case of this conventional steering rocker arm a, a gap is formed between the switch b and the switch opening c. This creates a risk that small objects, dust, etc., may enter the interior of the steering rocker arm a through this gap. Secondly, electrostatic discharge between the operator's body (e.g., fingers) and the electronic equipment (not shown) arranged inside the steering rocker arm a can occur through the gap. As a result of this electrostatic discharge, there is a risk of damage to the electronic equipment. Therefore, the conventional steering rocker arm a is particularly prone to defects. Summary of the Invention
[0004] The purpose of this invention is to provide a steering rocker arm that is particularly reliable and easy to assemble.
[0005] According to the independent claims, the objective is achieved by a switch module for a steering rocker arm, a method for assembling such a switch module, and a steering rocker arm for a motor vehicle.
[0006] The features, advantages, and advantageous configurations of the switch module according to the invention shall be regarded as the features, advantages, and advantageous configurations of the steering rocker arm according to the invention, and vice versa. The features, advantages, and advantageous configurations of the switch module according to the invention and / or the steering rocker arm according to the invention relate to the methods applied to the switch module according to the invention and / or the steering rocker arm according to the invention.
[0007] A first aspect of the invention relates to a switch module for a steering rocker arm. Here, the switch module has a switch. The switch has a journal socket corresponding to a journal element, which will be described in further detail below. Furthermore, the switch module has a carrier having a carrier element capable of being stressed in a non-destructive, reversible manner. A journal element is arranged on the stressed carrier element, wherein the journal element and the journal socket correspond to each other. In the assembled state of the switch module, the outer circumferential surface of the journal element and the inner circumferential surface of the journal socket are directly adjacent to each other. The journal element and the journal socket may each have a shape different from that of a straight cylinder.
[0008] The switch module also has a frame disposed on a carrier. A switch opening is formed in the frame, wherein the switch opening corresponds to the shape of the switch. This means that the wall of the frame is completely penetrated by the switch opening. The switch opening is adjacent to a material-free area of the frame. In the assembled state of the switch module, the frame is at least partially engaged around the carrier.
[0009] The switch in the switch module has an actuating portion and a fastening portion. The actuating portion and the fastening portion are connected to each other by a material bonding method. In other words, the switch is formed by the actuating portion and the fastening portion. In the switch module, the switch is arranged in a switch opening. This means that the switch extends through the switch opening. On the outside of the frame, the switch, together with the actuating portion, protrudes beyond the outer surface of the frame, while on the inside of the frame, the switch, together with the fastening portion, protrudes beyond the inner surface of the frame. The outer and inner surfaces of the frame are opposite to each other, with the switch opening extending completely through the frame and through both the outer and inner surfaces.
[0010] In the fully assembled position of the switch module, the switch and the carrier are fastened together because the journal element is locked into its journal socket, making the journal element and the journal socket coaxial. In other words, in the locked state, the longitudinal center axis of the journal element and the longitudinal center axis of the journal socket coincide. In this way, a fastening device is formed specifically between the carrier and the switch, wherein the carrier and the switch are connected to each other by the fastening device. Therefore, the carrier and the switch are fastened together by the fastening device.
[0011] Then, in order to configure the switch module in such a way that the steering rocker arm with the switch module is particularly reliable and easy to assemble, according to the first aspect of the invention, the frame for pre-assembly can be pushed onto the carrier in the pre-assembly direction. Here, the switch is held in the switch opening. In other words, during pre-assembly, the switch is held on the frame, for example because the switch extends through the switch opening. Furthermore, in order to reach the fully assembled position, the switch can be moved in the fully assembled direction. This means that the switch and the carrier can move toward each other so that the journal element locks into the journal socket. The switch and the carrier can move toward each other along the fully assembled direction. The pre-assembly direction is different from the fully assembled direction. In particular, the pre-assembly direction and the fully assembled direction are perpendicular to each other. Therefore, the fully assembled direction extends perpendicular to the pre-assembly direction, and vice versa.
[0012] Furthermore, it is specified that a carrier-side assembly ramp is arranged on the carrier element. The carrier-side assembly ramp is configured such that, for the pre-assembly of the switch module, it slides along the pre-assembly direction on the inner surface of the switch, subjecting the carrier element to stress. When the switch module is in a fully assembled state, the carrier has been inserted into the frame along the pre-assembly direction to engage the frame around the carrier. In order to lock the journal element into the journal socket, the switch and the carrier have been moved toward each other along the fully assembled direction within the switch module.
[0013] The carrier-side assembly ramp is configured to slide along the pre-assembly direction on the inner surface of the switch, for example, because the carrier-side assembly ramp is arranged according to the pre-assembly direction. Specifically, the carrier-side assembly ramp narrows the carrier in the region where the journal element is locked into the switch during pre-assembly. For example, the carrier is narrowed by the carrier-side assembly ramp at the journal element. In other words, the fully assembled direction of the switch and the inclined triangle of the carrier-side assembly ramp are arranged perpendicular to each other, where the inclined triangle characterizes the carrier-side assembly ramp.
[0014] In this way, a switch module that can be assembled particularly easily or at a particularly low cost is provided. This makes the steering rocker arm with this switch module particularly easy to assemble. Due to the arrangement of the assembly ramps on the carrier side, the pre-assembly direction of the switch module and the actuation direction of the switch are not aligned. The fully assembled direction of the switch and the actuation direction of the switch are particularly parallel to each other. Due to the fastening device, the switch is held particularly firmly on the carrier. Here, a particularly large retaining surface is advantageously formed, through which the journal element and the journal socket abut against each other over a large area. Furthermore, unintentional separation of the switch from the carrier is advantageously prevented because the assembly ramps of the carrier element and the actuation direction or fully assembled direction of the switch are arranged parallel to each other. In other words, the carrier element narrows or widens due to the assembly ramps, not along the actuation direction or fully assembled direction of the switch, but along the pre-assembly direction. Therefore, at the switch module, it is advantageous that a particularly large force must be applied to separate the switch from the carrier.
[0015] In another advantageous configuration of the switch module, the switch is in the form of a rocker switch. Therefore, the fastening device is in the form of a rotary joint. Thus, the switch, as a rocker switch, is pivotally mounted relative to the carrier via the fastening device or rotary joint. In this case, the journal element and the journal socket each have a cylindrical shape. If the cylindrical journal element is stationary in the cylindrical journal socket, and the journal element and journal socket are arranged coaxially, then the rotary joint is formed by the cylindrical journal element and the cylindrical journal socket. According to the above description, the rocker switch is in a state of pivotal mounting on the carrier, particularly on the carrier element, which means that the rocker switch is held particularly firmly and stably relative to the frame of the switch module. Therefore, the switch module with the rocker switch is particularly resistant to the loads generated during the use of the switch module.
[0016] According to another advantageous embodiment of the switching module, a carrier-side assembly ramp is formed on the journal element. Therefore, the side surface and / or distal top surface of the journal element have the carrier-side assembly ramp. In other words, the distal top surface and / or side surface are at least partially formed by the assembly ramp. Advantageously, the carrier-side assembly ramp and the journal element are integrally formed with each other in this manner. The assembly ramp is provided by the external shape of the journal element. The carrier can therefore be manufactured in a particularly material-saving manner because the formation of a journal element separate from the assembly ramp can be omitted.
[0017] According to another advantageous embodiment of the switch module, the inner surface of the switch has a switch-side assembly ramp. The switch-side assembly ramp and the carrier-side assembly ramp are configured to slide against each other during the pre-assembly of the switch module. In other words, the switch-side assembly ramp and the carrier-side assembly ramp slide against each other as the carrier and frame are assembled together in the pre-assembly direction. This interaction between the switch-side assembly ramp and the carrier-side assembly ramp further facilitates or simplifies the assembly or pre-assembly of the switch module.
[0018] In this case, it has further proven advantageous that, viewed from the pre-assembly direction, the inner surface of the switch has a first stress step that subjects the carrier element to stress and a second stress step that further subjects the carrier element to stress. Here, the first stress step is formed by the switch-side assembly ramp. The second stress step is formed by an inner surface portion of the switch, wherein the inner surface portion has a journal socket. In other words, the journal socket is formed in the inner surface portion. The journal socket is, in particular, a hole that extends completely through the inner surface portion of the switch. As further explained above, when the switch is pivotally held on the carrier or carrier element as a rocker switch, the hole extending through the inner surface portion, that is, the journal socket, is circular. Due to the gradual stress on the carrier element, introducing the carrier into the frame along the pre-assembly direction is particularly simple. This is because the force that undesirably acts laterally to the pre-assembly direction during the pushing of the carrier into the frame and drives the carrier away from the pre-assembly direction during the pushing into the frame is greater in the second stress step than in the first stress step. However, the second stress step only appears along a particularly short path portion, so it is advantageous that the large force is overcome or compensated only along this particularly short path portion.
[0019] In another advantageous configuration of the switch module, the switch has a switch-side pre-assembly unit, and the frame has a frame-side pre-assembly unit. The switch-side and frame-side pre-assembly units correspond to each other to form a pre-assembled arrangement. In this way, the switch and frame can be held in place in the pre-assembled position. To form the pre-assembled arrangement, the pre-assembly units interact with each other in a force-fit and / or form-fit manner. This means that during the assembly of the pre-assembled arrangement, a force-fit and / or form-fit is formed between the switch and the frame because the frame and switch are connected to each other through the pre-assembly units. Therefore, as a pre-assembled arrangement, the switch and frame are in a fixed state. The advantage of this is that the pre-assembled arrangement can be operated or moved particularly easily, ensuring that the switch and frame do not unintentionally separate from each other.
[0020] Preferably, the switch-side pre-assembly unit has a collar element. Here, the collar element protrudes vertically from the outer surface of the switch at two opposing ends. For example, the collar element has two collar bodies, one of which protrudes from the outer surface at the first end of the switch, and the other collar body protrudes from the outer surface at the second end of the switch. In the pre-assembly position, that is, when the pre-assembly arrangement has already been formed by the switch and the frame, the switch is supported on the frame by the collar element or collar body. In this case, the switch extends through the switch opening. In this way, the switch is suspended in the frame, thereby ensuring that the switch will not unintentionally fall out of the frame.
[0021] In another configuration of the collar element, the collar element fully engages around the lower edge of the switch. In both the pre-assembled and fully assembled positions of the switch—that is, when the switch module is fully assembled—the collar element, fully engaged around the lower edge of the switch, completely covers the gap between the frame and the switch. Because the collar element is formed on the lower edge of the switch, it is also formed on the fastening portion of the switch. This is because the fastening portion includes the lower edge. If the switch is positioned in the switch opening according to the pre-assembled position, the switch is supported on the inner surface of the frame by the collar element, and is held there. For example, the switch is suspended from the inner surface of the frame by the collar element. If the frame-side pre-assembly unit corresponds to the collar element, it can also be specified that the switch is clamped to or locked into the frame by the collar element to ensure a particularly reliable fit of the switch in or on the frame for the pre-assembly of the switch module.
[0022] Furthermore, in this configuration, the collar element fully engaged around the lower edge of the switch serves a dual function. The first function of the collar element is to enable the switch to be coupled to the frame via force and / or form fit, thereby creating a pre-assembled arrangement. The second function of the collar element is to cover the gap between the frame and the switch, which helps prevent objects, dust, etc., from entering the internal space of the switch module through the gap, i.e., through the switch itself.
[0023] Regarding the pre-assembly unit, according to another advantageous embodiment of the switch module, it has proven advantageous that the electrostatic discharge (ESD) protection element between the operator's body and the electronic equipment of the switch module is formed by the switch-side pre-assembly unit. This means that, in this case, the switch-side pre-assembly unit, particularly the collar element fully engaged around the lower edge, has a further function, especially as an ESD protection element. This is because the direct, material-free connection between the electronic equipment and the surrounding environment of the switch module is interrupted by the switch-side pre-assembly unit, particularly the collar element, which advantageously at least prevents ESD from occurring.
[0024] The protective labyrinth is advantageously formed by pre-assembly units on the switch side and frame side. The material-free connection between the switch module and the electronic equipment then extends in multiple curves and / or bends, particularly through 90 degrees in each case. Due to the protective labyrinth, it more effectively prevents objects or dust from falling into the internal space of the switch module and from electrostatic discharge.
[0025] According to another advantageous configuration of the switch module, the carrier has a carrier-side stop element. Furthermore, the frame has a frame-side stop element. Here, the carrier-side stop element and the frame-side stop element correspond to each other for pre-assembly of the switch module. Pre-assembly of the switch module includes the formation of a stop device, wherein the carrier and frame are stopped from each other in a stop position. In the stop position, the journal element and journal socket are arranged relative to each other along a common full assembly direction. In other words, for the pre-assembly of the switch module, the carrier and frame can move toward each other due to the stop device or due to the stop element until the journal element and journal socket are arranged along the common full assembly direction. The stop device is specified to operate in a force and / or form-fit manner, wherein once the journal element and journal socket are arranged along the common full assembly direction, the stop device prevents the carrier and frame from moving away from each other again. Alternatively or additionally, when the journal element and journal socket are arranged along the common full assembly direction, the stop device can prevent the carrier and frame from moving further toward each other. In other words, pulling the carrier out of the frame and / or pushing the carrier further into the frame is blocked by the stop device. Therefore, the process of placing the carrier with the frame along the pre-assembly direction is particularly simple. This similarly applies to the process of placing the carrier with a pre-assembly arrangement, wherein the pre-assembly arrangement has a frame and a switch.
[0026] Another aspect of the invention relates to a method for assembling a switch module designed according to the above description. Here, the switch is arranged in a pre-assembly position on a frame. This means that a pre-assembly arrangement is formed by the switch and the frame. In this case, the switch extends through a switch opening formed in the frame.
[0027] Furthermore, in the method for assembling the switch module, the carrier and the pre-assembled arrangement move toward each other along a common pre-assembly direction. This causes the assembly ramp formed on the carrier element of the carrier and the inner surface of the switch to slide against each other. This results in stress on the carrier element. In other words, the carrier element is stressed because the assembly ramp of the carrier element slides on the inner surface of the switch. Movement of the carrier and / or the pre-assembled arrangement occurs until the journal element of the carrier and the journal socket of the switch are arranged along a common full assembly direction.
[0028] If the journal element and journal socket are arranged relative to each other along a common fully assembled direction, the switch and carrier move toward each other along the fully assembled direction. For example, the switch is pushed toward the carrier relative to it. In this way, the journal element locks into the journal socket while relieving stress on the carrier element, such that the journal element and journal socket are arranged coaxially relative to each other. Before the journal element locks into the journal socket, it slides on the inner surface of the switch until it reaches the journal socket and finally locks into it.
[0029] Specifically, a fastening device is formed between the switch and the carrier in this manner, connecting the carrier and the switch. The fastening device is formed because the journal element locks into the journal socket. During the formation of the pre-assembled arrangement, that is, when the switch is arranged on the frame in the pre-assembled position, the actuating part of the switch protrudes beyond the outer surface of the frame on one side, while the fastening part of the switch protrudes beyond the inner surface of the frame on the other side. Here, the outer and inner surfaces of the frame are opposite to each other.
[0030] This method makes the switch module, and therefore the steering rocker arm for motor vehicles, particularly easy to assemble.
[0031] The present invention also includes improvements to the method according to the invention, which have features already described in conjunction with improvements to the switching module according to the invention. Therefore, corresponding improvements to the method according to the invention will not be described here.
[0032] According to another aspect of the invention, a steering rocker arm for a motor vehicle is provided. The steering rocker arm has a switch module designed according to the above description. It is conceivable that the steering rocker arm can be manufactured because a steering rocker arm body is first provided, which is then placed together with the fully assembled switch module. Since the switch module is particularly reliable and easy to assemble, a particularly reliable and easy-to-assemble steering rocker arm is thus provided.
[0033] The present invention also includes improvements to the steering rocker arm according to the invention, which have features already described in conjunction with improvements to the method according to the invention and / or the switching module according to the invention. Therefore, corresponding improvements to the steering rocker arm according to the invention will not be described here.
[0034] The present invention also includes combinations of features of the described embodiments. Attached Figure Description

[0048] In the accompanying drawings, the same or functionally identical elements are represented by the same reference numerals. Detailed Implementation
[0049] The following section will describe the switch module 1, the steering rocker arm 2, and the method for manufacturing the switch module 1.
[0050] Figure 1 A perspective view shows a steering rocker arm 2 for a motor vehicle. The steering rocker arm 2 has a steering rocker arm body 3 connected to a switch module 1. In other words, the switch module 1 is mounted into the steering rocker arm body 3. Thus, the steering rocker arm 2 is formed. The switch module 1 has a switch 4 and a frame 5, which will be described in more detail below. In this example, the switch 4 is in the form of a rocker switch.
[0051] Figure 2A perspective view shows a switch 4 or rocker switch, wherein the switch 4 has an actuating portion 6 and a retaining portion 7. The switch 4 is formed by the actuating portion 6 and the retaining portion 7, wherein the actuating portion 6 and the retaining portion 7 are integrally formed with each other. The switch 4 is formed integrally with the actuating portion 6 and the retaining portion 7. The switch 4 also has a journal socket 8, which is formed at the center of the switch 4 along the longitudinal length of the switch 4. The journal socket 8 is a channel hole that extends completely through the wall 9 of the switch 4. In this example, the switch 4 has one journal socket 8 on each side. An internal space 10 of the switch is formed between the mutually opposing walls 9 of the switch 4. The internal space 10 is the material-free space of the switch 4. The pivot axis 11 of the switch 4 is defined by the mutually directly opposing journal sockets 8, wherein the corresponding longitudinal central axis of the journal socket 8 coincides with the pivot axis 11 of the switch 4. The pivot axis 11 of the switch 4 intersects perpendicularly with the vertical axis 12 of the switch 4. A first collar body 14 is formed on the first end 13 of the switch 4. The other end 15 of switch 4 is opposite to the first end 13 of switch 4. Another collar body 16 is formed on the second end 15. The collar bodies 14 and 16 are part of the collar element 17. Here, the collar element 17 protrudes vertically from the outer surface 18 of switch 4. Therefore, the collar bodies 14 and 16 protrude from the outer surface 18.
[0052] The inner surface 19 of switch 4 has an assembly ramp 20. For example... Figure 1 As shown, in this example, switch 4 has two opposing assembly ramps 20 facing each other. This means that the two assembly ramps 20 face the internal space 10 of switch 4. To further describe switch module 1, referring to the pre-assembly direction 21, it also... Figure 1 As shown in the diagram. Along the pre-assembly direction 21, the switch 4 has a first stress step 22 in the internal space 10 or on the inner surface 19, wherein the first stress step 22 is formed by the switch-side assembly ramp 20. The switch 4 also has a second stress step 23, wherein the second stress step 23 is formed by the inner surface portion 19a of the switch 4. Here, the inner surface portion 19a with the second stress step 23 is arranged obliquely relative to the switch-side assembly ramp 20 or relative to the first stress step 22. Here, the inner surface portion 19a is a straight or flat inner surface portion of the inner surface 19 of the switch 4, wherein the straight inner surface portion 19a and the vertical axis 12 are arranged parallel to each other. Conversely, the corresponding switch-side assembly ramp 20 is arranged obliquely relative to the vertical axis 12. Furthermore, the switch-side assembly ramp 20 is arranged parallel to the pre-assembly direction 21. The inner surface portion 19a having or forming the second stress step 23 is completely extended through by the journal socket 8. In other words, the inner surface portion 19a has a corresponding journal socket 8.
[0053] Figure 3A partial perspective view of the carrier 24 is shown, wherein the carrier 24 has a carrier element 25, which is capable of being subjected to force in a non-destructive and reversible manner. For better orientation, Figure 3 The pre-assembly direction 21 is also shown in the diagram. Figure 3 It can also be seen that, in the current case, the carrier 24 has two carrier elements 25 facing each other. Here, the carrier elements 25 are spaced apart by a certain distance, which corresponds to the distance between the opposing walls 9 of the switch 4. A corresponding journal element 26 is arranged on the corresponding carrier element 25. The corresponding journal element 26 corresponds to a related journal socket 8. In this case, both the journal element 26 and the journal socket 8 are cylindrical. Here, the corresponding outer diameters of the corresponding journal element 26 and the corresponding journal socket 8 correspond to each other, so that the journal element 26 can be arranged coaxially in the journal socket 8. In other words, in the fully assembled state of the switch module 1, the pivot axis 11 of the journal socket 8 and the pivot axis 27 of the journal element 26 coincide. This means that the corresponding journal element 26 and the corresponding journal socket 8 correspond to each other.
[0054] The corresponding carrier element 25 has a carrier-side assembly ramp 28. This means that the corresponding carrier-side assembly ramp 28 is arranged on the corresponding carrier element 25. In this case, the carrier-side assembly ramp 28 is formed directly on the corresponding journal element 26. This means that the corresponding journal element 26 has a corresponding carrier-side assembly ramp 28. The corresponding carrier-side assembly ramp 28 is arranged obliquely relative to the pre-assembly direction 21. In addition, the corresponding carrier-side assembly ramp 28 is arranged obliquely relative to the pivot axis 27 of the carrier 24. Furthermore, the corresponding carrier-side assembly ramp 28 is arranged parallel to the vertical axis 29 of the carrier 24.
[0055] To better understand the position of the corresponding carrier-side assembly ramp 28, a hypothetical inclined triangle 30 is introduced. The hypothetical inclined triangle 30 is two-dimensional, therefore its hypotenuse and catheti are arranged in a common plane. Here, the hypothetical inclined triangle 30 is arranged perpendicular to the vertical axis 29 of the carrier 24. Furthermore, the hypothetical inclined triangle 30 is arranged perpendicular to the full assembly direction 31, which will be described in more detail below. Therefore, the vertical axis 29 of the carrier 24 and the full assembly direction 31 are parallel to each other, specifically, the vertical axis 29 of the carrier 24 and the full assembly direction 31 coincide.
[0056] Due to the carrier-side assembly ramp 28, the spacing between the opposing journal elements 26 narrows when viewed from the pre-assembly direction 21. The spacing between the journal elements 26 is, for example, arranged between the opposing top surfaces 32 of the journal elements 26.
[0057] Figure 4The frame 5 is shown in perspective, having an annular cylindrical portion 33 and another portion 34. A switch opening 35 is formed in the other portion 34. Here, the switch opening 35 extends completely through the material of the frame 5 on the other portion 34. This means that the switch opening 35 is a material-free area of the frame 5, particularly portion 34. The outer contour 36 of the switch opening 35 and the outer surface 18 of the switch 4 correspond to each other, such that the switch 4 can be inserted into or is able to be inserted into the switch opening 35. The longitudinal central axis 37 of the frame 5 and the pre-assembly direction 21 are parallel to each other, and in particular coincide with each other.
[0058] To assemble switch module 1, a pre-assembly arrangement 38 is first formed. The pre-assembly arrangement 38 is in... Figure 5 As shown in the side view. The pre-assembly arrangement 38 has a switch 4 and a frame 5. This means that, in order to form the pre-assembly arrangement 38, the switch 4 and the frame 5 are placed together. Here, the frame 5 and the switch 4 are in the state of being arranged in the pre-assembly position. In the pre-assembly position or in the pre-assembly arrangement 38, the switch 4 is arranged in the switch opening 35. In this case, the switch 4 is suspended by the collar element 17, that is, suspended from the inner surface 39 of the frame 5 by the collar bodies 14, 16 (see Figure 4 Here, switch 4 extends from the inner side 40 of frame 5 through switch opening 35 to the outer side 41 of frame 5, wherein both the actuating portion 6 and the fastening portion 7 of switch 4 protrude beyond the outer surface 42 of frame 5. This is in Figure 5 It can be seen particularly clearly that, as the pre-assembled arrangement 38 is formed by the frame 5 and the switch 4, the journal socket 8 protrudes beyond the outer surface 42 of the frame 5.
[0059] In the pre-assembly arrangement 38, the fastening part 7 is still partially arranged on the inner side 40 of the frame 5. In order to insert the switch 4 into the frame 5, that is, to form the pre-assembly arrangement 38, the switch 4 is inserted into the switch opening 35 of the frame 5 along the vertical axis 12 of the switch 4 until the switch 4 is adjacent to the inner surface 39 of the frame 5 through the collar element 17.
[0060] To form the pre-assembled arrangement 38, in this example, the switch 4 has a switch-side pre-assembly unit 43, and the frame 5 has a frame-side pre-assembly unit 44. In this case, the switch-side pre-assembly unit 43 is formed by a collar element 17. Furthermore, the frame-side pre-assembly unit 44 is formed by the inner surface 39 of the frame 5. The pre-assembly units 43 and 44 correspond to each other because the collar element 17 and the inner surface 39 of the frame 5 correspond to each other. Therefore, the switch 4 and the frame 5 can be held in a pre-assembled position by the pre-assembly units 43 and 44. This means that the pre-assembly units 43 and 44 correspond to each other to form the pre-assembled arrangement 38. Through the interaction of the pre-assembly units 43 and 44, a pre-assembly device is formed, by which the switch 4 and the frame 5 are held in the pre-assembled position.
[0061] Figure 6 Another configuration of switch 4 or rocker switch is shown in perspective. Here, the collar element 17 is fully engaged around the lower edge 45 of switch 4. Because the collar element 17 is fully engaged around the lower edge 45 of switch 4 or rocker switch, switch 4 is held particularly reliably in switch opening 35 in pre-assembled arrangement 38, as switch 4 is supported on the inner surface 39 of frame 5 over a particularly large area by the collar element 17.
[0062] Figure 7 The pre-assembly arrangement 38 is shown in perspective, in which the carrier 24 and the pre-assembly arrangement 38 are placed together. Figure 7 The view shows the carrier element 25 of the carrier 24, on which the journal element 26 is disposed together with the carrier-side assembly ramp 28. The carrier 24 and the pre-assembly arrangement 38 are arranged relative to each other at the longitudinal central axis 37 of the frame 5, such that the carrier 24 can pass through the annular cylindrical portion 33 of the frame 5. The carrier 24 and the pre-assembly arrangement 38 then move toward each other along a common pre-assembly direction 21. The carrier-side assembly ramp 28 is configured such that, for the pre-assembly of the switch module 1, it slides on the inner surface 19 of the switch 4 with the carrier element 25, and the carrier element 25 can be stressed in a non-destructive reversible manner, wherein the switch 4 is held in / on the frame 5 in the pre-assembly position. Thus, during the pre-assembly of the switch module 1, the carrier-side assembly ramp 28 contacts the inner surface 19 of the switch 4, particularly the area of the inner surface 19 where the switch-side assembly ramp 20 and therefore the first stress step 22 are disposed. This means that as the carrier 24 is pushed into the pre-assembly arrangement 38 along the pre-assembly direction 21, the carrier elements 25 of the carrier 24 are pressed toward each other because the journal elements 26 slide on the switch-side assembly ramp 20 via the carrier-side assembly ramp 28.
[0063] As the carrier 24 moves further along the pre-assembly direction 21 into or through the annular cylindrical portion 33 of the frame 5, the carrier-side assembly ramp 28 contacts the second stress step 23 of the switch 4, that is, contacts the inner surface portion 19a. In this way, the carrier element 25 is further stressed toward each other because the journal element 26 slides on the inner surface portion 19a via the carrier-side assembly ramp 28. The pre-assembly arrangement 38 and the carrier 24 move toward each other along the pre-assembly direction 21 until the vertical axis 12 of the switch 4 and the vertical axis 29 of the carrier 24 coincide. Once the vertical axes 12, 29 coincide, the journal socket 8 and the journal element 26 are arranged along the common full assembly direction 31. To prevent the carrier 24 and the pre-assembly arrangement 38 from moving too far or too little toward each other, the carrier 24 has a carrier-side stop element 46, while the frame 5 and the pre-assembly arrangement 38 have frame-side stop elements 47. Stopping elements 46 and 47 correspond to form a stopping device 48 (see Figure 8 The stop device 48 is configured to prevent the carrier 24 from disengaging relative to the pre-assembled arrangement 38 when the vertical axes 12 and 29 coincide. In other words, the stop device 48 is closed, for example by the locking of the stop elements 46 and 47, once the corresponding journal elements 26 and the corresponding journal sockets 8 are arranged along the common fully assembled direction 31.
[0064] Figure 8A partial side view of the pre-assembled arrangement 38 and the carrier 24 is shown, with the carrier 24 inserted into the frame 5, and the switch 4 or rocker switch and the carrier 24 locked together for complete assembly of the switch module 1. For this purpose, the carrier 24 and the switch 4 or rocker switch are moved toward each other along vertical axes 12, 29, which coincide, i.e., in the complete assembly direction 31, whereby the journal element 26 is coaxially locked into its respective associated journal socket 8 with the stress released from the corresponding carrier element 25. Here, the fastening portion 7 of the switch 4 is further moved in the direction of the inner side 40 of the frame 5, such that when the switch module 1 is in the complete assembly state, the switch 4 is arranged in the switch opening 35, with the switch 4 or rocker switch and the carrier 24 fastened together. The switch 4 and the carrier 24 are fastened together because the corresponding journal element 26 engages in the corresponding journal socket 8, with the journal element 26 and the journal socket 8 arranged coaxially relative to each other. In other words, the pivot axis 11 of switch 4 coincides with the pivot axis 27 of carrier 24. Since the corresponding journal element 26 and the corresponding journal socket 8 are both formed based on a right cylinder, a rotary joint 49 is formed during the complete assembly of switch module 1, that is, because switch 4 and carrier 24 move toward each other along the complete assembly direction 31. The axis of rotation of the rotary joint is formed by the journal element 26 and journal socket 8, which are arranged coaxially with each other. Through the rotary joint 49, that is, through the journal element 26 and journal socket 8, switch 4, as a rocker switch, is in a pivotally mounted state relative to carrier 24 and relative to frame 5. Here, switch 4 or rocker switch can pivot about the axis of rotation of rotary joint 49, that is, about pivot axes 11 and 27.
[0065] Figure 9 A partial perspective view of the rotary joint 49 is shown, through which the switch 4 and the carrier 24 are connected to each other. Furthermore, in Figure 9 As can be seen particularly clearly, the journal element 26 is engaged by the journal socket 8 over a particularly large area, which results in a particularly stable or reliable fit of the journal element 26 in the journal socket 8. This advantageously prevents the switch 4 or rocker switch from being pulled out of the switch module 1 against the fully assembled direction 31, because there is no ramp arranged against the fully assembled direction 31, which would facilitate pulling the switch 4 out of the switch module 1.
[0066] Figure 10 A partial cross-sectional view of switch module 1 is shown, wherein the lower edge 45 of switch 4 is arranged parallel to the plane of the drawing. Figure 10In the diagram, switch module 1 is shown in a fully assembled state, meaning that switch 4 is moved toward carrier 24 along the fully assembled direction 31 until journal element 26 engages with journal socket 8. Here, it can be seen particularly clearly that the carrier-side assembly ramp 28 involves a diameter less than half that of the corresponding journal element 26. This makes the corresponding journal element 26 particularly stable, thereby ensuring a particularly reliable fit of switch 4 on carrier 24.
[0067] Figure 11 The steering rocker arm body 3 is shown in a perspective partial view, in which the switch module 1 is inserted. For this purpose, the switch module 1 is either in the state described above or fully assembled. Figure 11 The gap 50 between the switch opening 35 and the switch 4 or rocker switch is shown, wherein, in this example, the gap 50 is completely covered by the collar element 17 of the switch 4. This is because the collar element 17 of the switch 4 is positioned on the inner side 40 of the frame 5 or on the inner surface 39 of the frame 5, and protrudes vertically from the outer surface 18 of the switch 4. Here, the collar element 17 protrudes from the outer surface 18 of the switch 4 at least to cover the gap 50. In this way, the collar element 17, i.e., the switch-side pre-assembled unit 43, forms a protective element, for example, preventing electrostatic discharge between the operator's body and the electronic equipment of the switch module 1. The operator's body includes, for example, the fingers of a human operator.
[0068] In this example, the protective element formed by the switch-side pre-assembly unit 43 or the collar element 17 is also configured to prevent objects, dust, etc., from entering through the switch opening 35 via the switch 4 or rocker switch. Furthermore, due to the collar element 17, observation through the gap 50 is blocked, resulting in a particularly pleasing appearance for the switch module 1 and therefore the steering rocker arm 2. The collar element 17 and the portion 34 of the frame 5 in which the switch opening 35 is formed particularly preferably interact as a labyrinth seal, resulting in a protective labyrinth formed by the interaction of the switch-side pre-assembly unit 43 and the frame 5.
[0069] Figure 11 The diagram also shows how the fully assembled switch module 1 is inserted (e.g., pushed into) the steering rocker arm body 3. If the switch module 1 is in a state of engagement or connection to the steering rocker arm body 3 according to its intended use, the steering rocker arm 2 is formed (see...). Figure 1 ).
