Description

[0001] The invention relates to a motor vehicle handle with a receiving space formed by side walls, a bottom wall, and a top wall, at least one electronic component designed to detect an operation of the motor vehicle handle and arranged within the receiving space, and potting material introduced into the receiving space, which forms a potting surface within the receiving space. The present invention also relates to a method for manufacturing such a motor vehicle handle.

[0002] Familiar automotive handlebars feature a housing-like structure with a compartment containing electronic components such as a printed circuit board (PCB), sensors (which may be mounted on the PCB), and other electronic components, such as processors mounted on the PCB that interact with the sensors. The challenge lies in effectively protecting these components from undesirable mechanical impacts and environmental influences such as moisture, dust, and temperature fluctuations. One known approach is to completely encapsulate the PCB, along with its electronics and sensors, with potting compound.While this option offers a high level of protection against external influences, it complicates the precise detection and processing of the vehicle handle's operation. This is because the functionality of a sensor that relies on relative movement is compromised by complete encapsulation, as the housing, which deforms during actuation, cannot move relative to the sensor. Another known option is to encapsulate the circuit board, other electronics, and sensors in an additional housing within the vehicle handle. This alternative requires a reliable seal around the gaps of the additional housing to protect the electronics from environmental influences, which complicates the manufacturing process and potentially incurs additional costs.

[0003] A motor vehicle handling method of the above-mentioned type is known, among other places, from EP 3 467 241 A1.

[0004] The invention aims to provide a solution that offers improved vehicle handling in a structurally simple manner, reliably protecting electronic components against external influences without impairing the vehicle's operation. The invention is intended to enable cost-effective and simple manufacturing by providing innovative protection for electronic components.

[0005] This problem is solved according to the invention by a motor vehicle handle according to the main claim, comprising a receiving space formed by side walls, a bottom wall and a top wall, at least one electronic component designed for detecting an operation of the motor vehicle handle, which is arranged within the receiving space, a filling opening designed for filling potting material into the receiving space for a potting process, a ventilation opening designed for ventilating the receiving space for the potting process, and an overflow nozzle with an overflow opening designed for draining excess potting material during the potting process, wherein the potting material introduced into the receiving space through the filling opening during the potting process forms an exposed potting material surface within the receiving space after the potting process.which divides the receiving chamber into a first receiving sub-chamber which is filled with the potting material and into a second receiving sub-chamber which is free of potting material, wherein the overflow nozzle extends through the potting material and through the bottom wall and, after the potting process, the overflow opening is flush with the potting material surface, and wherein, after the potting process, the filling opening and the overflow nozzle are sealed with the introduced potting material.

[0006] The object of the invention is also achieved by a method according to subsidiary claim 11, for manufacturing a motor vehicle handle, which has a receiving space formed by side walls, a bottom wall and a top wall, at least one electronic component designed for detecting an operation of the motor vehicle handle, which is arranged within the receiving space, a filling opening designed for a potting process for filling potting material into the receiving space, a ventilation opening designed for ventilating the receiving space for the potting process, and an overflow nozzle with an overflow opening designed for the potting process for draining excess potting material, wherein the method for the potting process comprises the steps: providing the receiving space, introducing potting material through the filling opening into the receiving space,until the applied potting material forms a potting surface which divides the receiving space into a first receiving sub-space which is filled with the potting material and into a second receiving sub-space which is free of potting material, and until the filling opening and the overflow nozzle are sealed with the applied potting material.

[0007] Advantageous and appropriate embodiments and further developments of the invention are set out in dependent claims 2 to 10 and 12 and 13, respectively.

[0008] The invention provides a vehicle handle that offers an improved solution for the protection and / or functional accuracy of at least one electronic component by employing an innovative design and manufacturing principle to meet the requirements for weather resistance, functionality, and cost-efficiency. The vehicle handle according to the invention can be a vehicle door handle or a handle for flaps on or in the vehicle.By dividing the receiving space according to the invention into a first receiving sub-space, which is filled with the potting material, and a second receiving sub-space, which is free of potting material, the functionality of a sensory electronic component is ensured by the second receiving sub-space allowing movement of the wall of the receiving space, which is deformed during actuation, relative to the sensory electronic component. This movement is not possible if the receiving space, and thus the sensory component, is completely potted. Furthermore, the ventilation opening designed to ventilate the receiving space during the potting process prevents a negative pressure from forming within the receiving space, thus protecting the at least one electronic component from damage.According to the invention, the overflow opening of the overflow nozzle defines the fill level of the potting material within the receiving chamber, wherein the fill level corresponds to the surface of the potting material, which is flush with the overflow opening. The defined and thus predetermined fill level of the potting material is therefore, according to the invention, dependent only on the geometric tolerances of the housing-like receiving chamber and not on dosing tolerances of the introduced potting material.

[0009] To achieve a desired fill level of the potting material within the receiving space, the invention provides in one embodiment that the overflow opening is arranged between the bottom wall and the ventilation opening.

[0010] According to a further embodiment of the invention, it is advantageous if the ventilation opening is arranged between the ceiling wall and the overflow opening. Alternatively, it is also conceivable that the ventilation opening is formed in the ceiling wall.

[0011] In a further embodiment, the invention provides that the electronic component comprises a printed circuit board, a first section of which is arranged within the potting material and a second section of which is arranged in the second receiving compartment. It is conceivable that an inductive sensor with at least one conductor coil for detecting deformations of a wall of the receiving compartment is arranged on the printed circuit board in the second receiving compartment, wherein at least one metallic target for sensory interaction with the at least one conductor coil is arranged on the wall opposite the inductive sensor. Alternatively, it could also be a capacitive sensor arranged and mounted on the printed circuit board.

[0012] For an efficient pouring process, the invention further provides that the filling opening is designed to extend through or through the bottom wall.

[0013] With a view to an effective and reliable sealing of the ventilation opening, a further embodiment of the invention provides that the ventilation opening is formed on a ventilation nozzle which extends from the ventilation opening arranged in the second receiving sub-chamber through the casting material towards the bottom wall and opens into a connecting passage formed in one of the side walls.

[0014] With regard to the effective and reliable sealing of the ventilation opening, it is advantageous in a further embodiment of the invention if an outlet tray is arranged outside the receiving space, into which the connecting passage opens.

[0015] To remove excess potting material, the invention provides in an embodiment that the overflow nozzle extends towards and through the bottom wall and is connected to an outlet nozzle via a connecting channel which is arranged outside the receiving space and which extends along the bottom wall.

[0016] In an embodiment of the invention, for the closure of the ventilation opening without a further process step, it is provided that the outlet nozzle has an outlet opening which is arranged within the outlet tray and which opens within the outlet tray.

[0017] This makes it possible, in a further embodiment of the invention, for the ventilation opening to be sealed with the potting material after the potting process. It is advantageous that no additional leak test is necessary and that no separate sealing plug for the ventilation opening needs to be provided.

[0018] In the embodiment of the method, it is particularly advantageous if, during the introduction of potting material, excess potting material is directed via the overflow nozzle and a connecting channel arranged outside the receiving space to an outlet tray arranged outside the receiving space, and the introduction of potting material is stopped when the excess potting material in the outlet tray reaches a fill level which covers a connecting passage formed in one of the side walls and connected to a ventilation nozzle of the ventilation opening.

[0019] Finally, in a further embodiment of the method, the invention provides that after the introduction of the potting material has been completed, the discharge tray and / or the connecting channel are removed.

[0020] It is understood that the features mentioned above and those to be explained below can be used not only in the combinations specified, but also in other combinations or individually, without departing from the scope of the present invention. The scope of the invention is defined solely by the claims.

[0021] Further details, features and advantages of the subject matter of the invention will become apparent from the following description in conjunction with the drawing, in which an exemplary and preferred embodiment of the invention is shown.

[0022] The drawing shows: Fig. 1 A schematic and lateral sectional view of a motor vehicle handle according to the invention during a first step of a potting process with a potting material, Fig. 2 a schematic and lateral sectional view of the motor vehicle handle according to the invention during a second step of the potting process with the potting material, Fig. 3 a schematic and lateral sectional view of the motor vehicle handle according to the invention during a third step of the potting process with the potting material, Fig. 4 a schematic and lateral sectional view of the motor vehicle handle according to the invention during a fourth step of the potting process with the potting material, Fig. 5 a schematic and lateral sectional view of the motor vehicle handle according to the invention during a fifth step of the potting process with the potting material, Fig. 6 a schematic and lateral sectional view of the motor vehicle handle according to the invention during a sixth step of the potting process with the potting material and Fig. 7 a schematic and lateral sectional view of the motor vehicle handle according to the invention after the potting process.

[0023] In the Fig. Figures 1 to 7 show a vehicle handle 1 according to the invention in schematic and sectional side views. The schematically depicted vehicle handle 1 can be a vehicle door handle or a handle for flaps on or in a vehicle, wherein the vehicle handle 1 has a receiving space 2 formed by side walls 3, a bottom wall 4, and a top wall 5. Within the receiving space 2, at least one electronic component 6, designed to detect operation of the vehicle handle 1, is arranged, which is only schematically indicated in the figures. The electronic component 6 has a circuit board 7, which can be equipped with one or more sensors.For example, it is conceivable that an inductive sensor with at least one conductor coil for detecting deformations of one of the walls 3, 4 and / or 5 of the receiving space 2 is arranged on the circuit board 7, wherein at least one metallic target for sensory interaction with the at least one conductor coil is arranged on the wall opposite the inductive sensor. Alternatively, it could also be a capacitive sensor, which is arranged and mounted on the circuit board and which is designed to detect an operator approaching the vehicle handle 1.

[0024] The further construction of the motor vehicle handle 1 according to the invention is described below. The following description refers in its entirety to the Fig. 1 to 7, where the Fig. Figures 1 to 6 show individual steps of a potting process for the motor vehicle handle 1 using a potting material 8, whereas in Fig. Figure 7 shows the handling of the motor vehicle 1 after the potting process and after optional post-processing steps.

[0025] The motor vehicle handle 1 according to the invention has a filling opening 9, which is designed for the potting process for filling potting material 8 into the receiving chamber 2. In the Fig. Figures 1 to 6 illustrate the filling or introduction of the potting material 8 into the receiving chamber 2, indicated by arrow 10. In the embodiment shown in the figures, the filling opening 9 is formed in the bottom wall 4. More precisely, the filling opening 9 extends through the bottom wall 4. Alternatively, the filling opening 9 can also be formed on another wall, which depends on the viscosity of the potting material 2 and its curing rate. The filling opening 9 is located at the end of a filling nozzle 11, which projects from the bottom wall 4 outside the receiving chamber 2. The filling nozzle 11 can be formed, at least partially, as part of the bottom wall 4.

[0026] Furthermore, the vehicle handle 1 according to the invention has a ventilation opening 12. The ventilation opening 12 is designed to ventilate the receiving chamber 2 and to prevent negative pressure within the receiving chamber 2 during the potting process. The ventilation opening 12 could, for example, be formed in one of the side walls 3 or in the top wall 5, but this would necessitate the use of a plug to seal the receiving chamber 2 and would disadvantageously represent an additional component. In the invention and in the Fig. In the vehicle handle 1 shown in Figures 1 to 7, the ventilation opening 12 is formed on a ventilation duct 14. The ventilation duct 14 extends from the bottom wall 4 towards the top wall 5, with one longitudinal end of the ventilation duct 14 having the ventilation opening 12, which is located within the receiving space 2, whereas the other longitudinal end of the ventilation duct 14 opens into a connecting passage 15 at the bottom wall 4. This connecting passage 15 is formed in one of the side walls 3 and extends through this side wall 3, thus forming a passage out of the receiving space 2. The ventilation duct 14 therefore extends from the ventilation opening 12 located in the receiving space 2 towards the bottom wall 4 and opens into the connecting passage 15 formed in the side wall 3.The ventilation nozzle 14 can be designed at least partially as part of a side wall 3 and / or as part of the bottom wall 4.

[0027] Finally, the vehicle handle 1 according to the invention has an overflow spout 16 with an overflow opening 17. The overflow opening 17 is designed for the drainage of excess potting material 8 during the potting process. Furthermore, the overflow opening 17 is arranged within the receiving space 2. More precisely, the overflow opening 17 is located between the bottom wall 4 and the ventilation opening 12. The ventilation opening 12 is then further arranged between the top wall 5 and the overflow opening 17.

[0028] How the Fig. As can be seen from sections 1 to 6, an outlet tray 18 is arranged outside the receiving chamber 2. The connecting passage 15, which is connected to the ventilation nozzle 14, opens into the outlet tray 18. The outlet tray 18 has a tray base 19, a tray side wall 20, and an open tray rim 21 opposite the tray base 19. The outlet tray 18 is connected to and attached to one of the side walls 3, and the outlet tray 18 can be formed at least partially as part of the side wall 3 and / or the base wall 4. An outlet nozzle 22 extends through the tray base 19 and has an outlet opening 23 located within the outlet tray 18 and opening within the outlet tray 18. The outlet opening 23 of the outlet nozzle 22 is arranged between the edge of the tub 21 and the bottom of the tub 19.Furthermore, the outlet opening 23 of the outlet nozzle 22 is arranged between the rim of the basin 21 and the connecting passage 15. The overflow nozzle 16 extends towards and through the bottom wall 4 and is connected to an outlet nozzle 22 via a connecting channel 24. The connecting channel 24 is arranged outside the receiving chamber 2 and extends along the bottom wall 4.

[0029] The advantages of the design of the vehicle handle 1 according to the invention become apparent from the following description of the method for manufacturing the vehicle handle 1, which comprises the receiving chamber 2, formed by the side walls 3, the bottom wall 4, and the top wall 5; at least one electronic component 6, designed to detect operation of the vehicle handle 1 and arranged within the receiving chamber 2; the filling opening 9, designed for filling the receiving chamber 2 with potting material 8 for the potting process; the ventilation opening 12, designed for ventilating the receiving chamber 2 for the potting process; and the overflow nozzle 16 with the overflow opening 17, designed for draining excess potting material 8 during the potting process. In a first step of the potting process method, the receiving chamber 2 of the vehicle handle 1 is provided.This can be a single-piece, gap-free receiving chamber 2, or alternatively, the receiving chamber 2 of the vehicle handle 1 can be formed from several shells that can be welded together. After the step of providing the receiving chamber 2, the next step is to introduce or fill the receiving chamber 2 through the filling opening 9, as shown in the [reference]. Fig. 1 to 6 are indicated by the respective arrow 10. The potting material 8 passes through the filling nozzle 11 to the filling opening 9 formed in and opening into the bottom wall 4.

[0030] From the filling opening 9, the potting material 8 enters the receiving chamber 2 and distributes itself evenly there, as described in the Fig. 2 and Fig. 3 is represented by the arrows 25. The height of the casting material 8 introduced into the receiving space 2 increases continuously, whereby the introduced or filled casting material 8 forms a casting material surface 26 within the receiving space 2, which migrates towards the ceiling wall 5 during the casting process, as shown by the Fig. 2 and Fig. 3 can be seen. The potting material surface 26 divides the receiving space 2 into a first receiving sub-space 27, which is filled with the potting material 8, and into a second receiving sub-space 28, which is free of potting material 8.

[0031] As the Fig. Figure 3 further shows that during the casting process, the surface of the casting material 26 migrates or rises towards the ceiling wall 5 until it reaches the overflow opening 17 of the overflow spigot 16. In other words, the receiving chamber 2 fills with casting material 8 starting from the bottom wall 4 and moving towards the ceiling wall 5. As more casting material 8 is poured into the receiving chamber 2, it is conveyed via the overflow opening 17, the overflow spigot 16, the connecting channel 24, the outlet spigot 22, and the outlet opening 23 to the outlet tray 18. Once the overflow spigot 16, the connecting channel 24, and the outlet spigot 22 are filled with casting material 8, casting material 8 emerges from the outlet opening 23, as shown in the figure. Fig. Figure 4 shows that the casting material 8 emerging from the outlet opening 23 then collects on the bottom of the trough 19 within the outlet trough 18, whereby the fill level 29 of the casting material 8 accumulating in the outlet trough 18 increases, as shown in Figure 4. Fig. Figure 5 shows that, consequently, when potting material 8 is introduced or poured, excess potting material 8 is directed via the overflow nozzle 16 and the connecting channel 24, located outside the receiving chamber 2, to the discharge tray 18, also located outside the receiving chamber 2. Therefore, during the potting process, the receiving chamber 2 can only be filled with potting material 8 up to the overflow opening 17. The arrangement of the overflow opening 17 within the receiving chamber 2 thus defines the arrangement of the potting material surface 26. Fig. Figures 4 to 7 show that the potting material surface 26 is flush with the outlet opening 17, so that a maximum amount of potting material 8 is arranged and filled within the receiving space 2. As can be seen from the Fig. As can be seen from Figures 3 to 7, a first section 30 of the electronic component 6 is arranged within the potting material 8, whereas a second section 31 of the electronic component 6 is arranged in the second receiving sub-space 28.

[0032] During the potting process, the receiving chamber 2 is ventilated via the ventilation opening 12 to prevent negative pressure within the receiving chamber 2. Ventilation is stopped when a sufficient quantity of excess potting material 8 has accumulated in the discharge tray 18, as is the case in Fig. 6 is shown. As in Fig. As shown in Figure 6, the excess potting material 8 rises within the discharge tray 18 towards the tray edge 21, whereby the connecting channel 24 and a section of the vent 14 are filled with excess potting material 8 as they rise. Venting of the receiving chamber 2 is no longer possible when the connecting channel 24 is filled with the excess potting material 8 from the discharge tray 18. Furthermore, venting is no longer necessary, as the potting process is complete when at least the connecting channel 24 is filled with excess potting material 8, as shown in Figure 6. Fig. 6 is shown. According to the Fig. From 4 to 7, the ventilation nozzle 14 extends from the ventilation opening 12 located in the second receiving sub-chamber 28 through the casting material 8 towards the bottom wall 4, wherein the overflow nozzle 16 extends through the casting material 8 and through the bottom wall 4, and after the casting process the overflow opening 17 is arranged flush with the casting material surface 26, as is the case, for example, in Fig. Figure 6 shows that the potting compound 8 is introduced or poured in until the filling opening 9 and the overflow nozzle 16 are sealed with the potting compound 8. Accordingly, after the potting process, the filling opening 9 and the overflow nozzle 16 are sealed with the potting compound 8, and the ventilation opening 12 is also sealed due to the connection passage 15 being closed with excess potting compound 8.

[0033] The introduction of potting compound 8 into the receiving chamber 2 is completed when the excess potting compound 8 in the discharge tray 18 reaches a fill level 29 that covers the connecting passage 15 formed in the side walls 3 and connected to the ventilation nozzle 14 of the ventilation opening 12. The ventilation nozzle 14 is therefore sealed by the excess potting compound 8 without any further process step, so that no additional leak test is required and no separate sealing plug is needed for the ventilation nozzle 14 or the ventilation opening 12. The size of the seal for the ventilation opening 12 is defined by the arrangement of the discharge opening 23 or by the height of the discharge nozzle 22.The closer the outlet opening 23 of the outlet nozzle 22 is moved towards the ceiling wall 5, the more the excess grout 8 rises within the ventilation nozzle 14 towards the ceiling wall 5.

[0034] The Fig. Figure 7 shows the vehicle handling 1 after the potting process and after an optional post-processing step. This post-processing step involves removing the outlet tray 18 and / or the connecting channel 24 after the potting process has been completed. Additionally, the filler neck 11 and the overflow neck 16 can be removed up to the bottom wall 4 after the potting process.

[0035] The described invention is, of course, not limited to the embodiment described and illustrated. Numerous modifications, obvious to those skilled in the art according to the intended application, can be made to the embodiment shown in the drawing without departing from the scope of the invention. Those skilled in the art will recognize that the receiving chamber 2 can be formed in multiple parts and can, for example, have an upper shell and a lower shell. From the perspective of the invention, it is important that the second receiving chamber 28 is gap-free, so that, in an embodiment with an upper shell and a lower shell, the gap-forming connection between the upper shell and the lower shell is located in the first receiving chamber 27 and is sealed by the cast-in casting material 8 after the casting process.The invention includes everything contained in the description and / or shown in the drawing, including anything that would be obvious to a person skilled in the art in contrast to the specific embodiment.
