Description

Technical Field

[0001] This application relates to a lawnmower robot with a battery pack housing. Background Technology

[0002] A lawnmower robot with a battery pack housing is known. A replaceable battery pack can be detachably fixed to a battery pack housing interface within the housing. This enables a mechanical and electrical connection between the battery pack and the lawnmower robot, providing power to the robot. Summary of the Invention

[0003] This application relates to a lawnmower robot with a battery pack housing, wherein the battery pack housing includes a first interface for a first battery pack receiving interface and a second interface, different from the first interface, for a second battery pack receiving interface of a different size. This allows for a simple configuration of a lawnmower robot for using different battery packs. For example, the lawnmower robot may have an 18V DIY or 18V professional-grade battery pack receiving interface and thus be driven by different battery packs. The battery pack is therefore configured to be received via the first or second battery pack receiving interface. The first or second battery pack receiving interface is further configured to connect to or be received on the first or second interface of the battery pack housing. Therefore, during production, the first or second battery pack receiving interface is arranged as a configuration component on the first or second interface of the battery pack housing.

[0004] The proposed design involves constructing the first and second interfaces parallel to each other, particularly for the translational accommodating of the first or second battery pack accommodating interface. These interfaces are specifically constructed as guide rails, preferably U-shaped profile rails. This allows for intuitive guidance or accommodating the battery pack accommodating interface within or at the battery pack accommodating compartment. The U-shaped profile of each guide rail is formed by the guide surface, base surface, and / or bottom plane or base surface of the battery pack accommodating compartment. A wing plate extends vertically or at a right angle upwards from this U-shaped profile. An additional wing plate extends from this wing plate perpendicularly and parallel to the guide surface, base surface, and / or bottom plane or base surface. The first and second interfaces each include two U-shaped profile guide rails with opposing openings.

[0005] The proposed solution is that the first and second interfaces are constructed as parallel offset guide tracks, particularly having an axial offset transverse to the guide direction and / or insertion direction, and especially having a common guide plane or base plane. This provides a secure hold perpendicular to the insertion direction of the battery pack receiving interface or perpendicular to the battery pack fixed to the battery pack receiving interface.

[0006] The proposed feature is that the first and second interfaces share a common mirror-symmetric plane. Specifically, the retaining devices or guide rails of the first and second interfaces have different distances relative to the mirror-symmetric plane. Furthermore, the retaining devices or guide rails of the first and second interfaces preferably have the same profile, and especially the same dimensions.

[0007] The proposed design involves the first and second interfaces being constructed as two right-angled, reverse-opening, three-sided closed axial guide rails, particularly as U-shaped profile rails. The first and second interfaces are integrally constructed with the battery pack housing or its shell.

[0008] The proposed design is that the first and second interfaces are complementary in shape-locking connection to the first and second battery pack receiving interfaces. Specifically, the first or second battery pack receiving interface has two opposing L-shaped tracks that are shape-lockingly embedded in the U-shaped profile of the first or second interface. This allows for axial or translational insertion of the first or second battery pack receiving interface into the first or second interface. Axial fixation is achieved, in particular, through connection to the end face of the battery pack receiving compartment, especially through a threaded connection.

[0009] The first interface and the second interface have a common bottom surface, which defines or constitutes a bottom plane.

[0010] The proposed solution is that the first battery pack receiving interface and / or the second battery pack receiving interface includes a first battery pack receiving interface bracket and / or a second battery pack receiving interface bracket for threaded connection to the end face of the battery pack receiving compartment, and in particular, the bracket arm lengths of the first battery pack receiving interface bracket and the second battery pack receiving interface bracket differ from each other, especially in their extension dimensions perpendicular to the plane of mirror symmetry.

[0011] The proposed feature is that the first interface, particularly the upper side of the guide rail of the first interface, and preferably the surface of the U-shaped wing plate of the guide rail of the first interface, provides a mating surface for the second battery pack receiving interface for fixing to the second interface. This improves the stability of the second battery pack receiving interface and allows the second battery pack receiving interface to overlap or surround the first interface.

[0012] Furthermore, this application also relates to a lawnmower robot having a first battery pack receiving interface or a second battery pack receiving interface housed on the first interface or the second interface. The lawnmower robot particularly further includes a first battery pack or a second battery pack compatible with the first battery pack receiving interface or the second battery pack receiving interface, especially an 18V battery pack. The battery pack is particularly equipped with a replaceable battery pack, especially a replaceable battery pack suitable for hand tools or gardening equipment. Attached Figure Description

[0015] Figure 1 A lawnmower robot 10 according to this application is shown, which has a battery pack housing 12. The lawnmower robot 10 includes a moving unit 100 and a cutting unit 101 (see [link]). Figure 2 The mobile unit 100 includes wheels 102 driven by a single wheel motor (not shown). These wheels are rear wheels. Additionally, the lawnmower robot 10 also includes front-side steering wheels 105 (see [link to documentation]). Figure 2Driven by a single wheel, the mowing robot possesses mobility. The cutting unit 101 (not shown in detail) includes multiple cutting blades fixed to a blade disc and is driven by a motor (not shown, but arranged inside the housing 103 of the mowing robot 10) for driving the cutting unit 101. To achieve autonomous navigation and area operation, the mowing robot 10 includes sensors (not shown or described here, as those skilled in the art are well aware of them) and control or regulation units, possibly including a processor unit. These components enable the mowing robot to autonomously navigate its working environment and perform trimming or mowing operations on the work area. The blade disc rotates substantially parallel to the travel surface or placement surface 104. The cutting unit 101 is configured for cutting grass. The mowing robot 10 includes a battery pack housing 12, which is located in... Figure 1 The interior is closed by a cover 120. The cover 120 is pivotally held on a hinge 121 about a hinge axis 122. The cover 120 can be unlocked from the locked position and manually opened by operating a button 123.

[0016] exist Figure 2-4 The image shows a lawnmower robot 10 with an open battery pack receiving compartment 12. The battery pack receiving compartment 12 includes a first interface 14 for a first battery pack receiving interface 16 (see especially...). Figure 3 and Figure 7 ) and a second interface 18 of a different size for a second battery pack receiving interface 20, which is different from the first battery pack receiving interface 16 (see especially) Figure 2 , Figure 4 , Figure 7 The first battery pack receiving interface 16 (see also...) Figure 5 A second battery pack receiving interface 20 is provided for accommodating an 18V DIY battery pack (see also...). Figure 6 A 18V professional-grade battery pack (not shown) is provided for accommodating the battery packs. These battery packs can be slidably mounted or fixed to the first battery pack accommodating interface 16 or the second battery pack accommodating interface 20 along the accommodating direction 22. The first battery pack accommodating interface 16 and the second battery pack accommodating interface 20 are at least provided for mechanical connection with the corresponding first interface 14 or second interface 18, preferably for mechanical and electrical connection. The second battery pack accommodating interface 20 is provided for accommodating a second battery pack of a different size than the first battery pack, such as an 18V battery pack suitable for professional users, such as the Bosch ProCORE battery pack.

[0017] Therefore, the first interface 14 and the second interface 18 are configured to accommodate the first battery pack receiving interface 16 or the second battery pack receiving interface 20. The first battery pack receiving interface 16 or the second battery pack receiving interface 20 is further configured for detachably connecting to or accommodating the first battery pack or the second battery pack, wherein the first battery pack and the second battery pack are of different sizes or at least cannot be fitted to a single battery pack interface. Therefore, the first battery pack receiving interface 16 or the second battery pack receiving interface 20 is a configuration component that can be selectively arranged by the user on the first interface 14 or the second interface 18 of the battery pack receiving compartment 12 during the production process of the lawnmower robot 10 or when necessary.

[0018] from Figure 2-5 As can be seen, the first interface 14 and the second interface 18 are constructed parallel to each other with respect to the receiving axis 24, especially the receiving interface 16 for translating the first battery pack (see...). Figure 3 ) or second battery pack receiving interface 20 (see Figure 2 , Figure 4 These interfaces particularly have guide rails 26a, 26b, 28a, 28b, preferably guide rails 26a, 26b, 28a, 28b forming a U-shaped profile. The U-shaped profile of each guide rail 26a, 26b, 28a, 28b is formed by or includes the aforementioned surfaces, such as a guide surface, a base surface, and / or a bottom surface 29. The bottom surface may be located in the bottom plane of the battery pack housing 12. First wing plates 30a, 30b, 32a, 32b extend vertically or at right angles upward from the guide surface, base surface, and / or bottom surface 29, respectively. From the first wing plates 30a, 30b, 32a, 32b, additional wing plates 34a, 34b, 36a, 36b extend parallel to the guide surface, base surface, and / or bottom surface 29, i.e., particularly perpendicular to the first wing plates 30a, 30b, 32a, 32b, and especially extending toward the mirror symmetry plane 38. Therefore, the first interface 14 and the second interface 18 each include two U-shaped guide rails 26a, 26b, 28a, and 28b with opposite openings. The guide surface, base surface, and / or bottom surface 29 are substantially parallel to the placement surface 104 (see [link to documentation]). Figure 2 Construction. It is possible that the guide surface, base surface and / or bottom surface 29 may also be constructed as an upwardly inclined surface (from the opening to the end face of the battery pack housing 12) relative to the battery pack housing 12, so that liquid, especially water, can flow out when the lawnmower robot 10 is in a horizontal position. Figure 2 Arrow 31 is shown, which defines the up (upward), down (downward), right, and left directions from the perspective of viewing the lawnmower robot 10 from the rear or the battery pack housing 12 from the rear.

[0019] The first interface 14 and the second interface 18 are configured as parallel offset guide rails 26a, 26b, 28a, 28b. The first and second interfaces are axially offset from each other and relative to the mirror symmetry plane 38 or the intermediate plane of the battery pack housing 12. The first guide rails 26a and 26b are equidistant from the mirror symmetry plane 38 on opposite sides of the mirror symmetry plane. The second guide rails 28a and 28b are similarly axially offset relative to the first guide rails. The first and second interfaces particularly share a common guide plane or base plane, namely a guide surface, base surface, and / or bottom surface 29. The first and second interfaces are arranged within the common base plane, perpendicular to the mirror symmetry plane 38.

[0020] First interface 14 and second interface 18 (see...) Figure 2 , Figure 3 , Figure 4 The first and second interfaces 14 and 18 share a common mirror-symmetric plane 38. Specifically, the retaining device or guide rail of the first interface 14 has different distances 40 and 42 relative to the guide rail of the second interface 18 about the mirror-symmetric plane 38. In particular, the retaining devices or guide rails 26a, 26b, 28a, and 28b of the first and second interfaces 14 and 18 have the same profile, preferably at least substantially the same dimensions (wall thickness, height, width, and length). The first interface 14 and 18 are particularly constructed as two right-angled, reverse-opening, three-sided closed axial guide rails. Therefore, the first and second interfaces constitute a U-shaped profile rail with reverse openings. The first interface 14 and 18 are particularly integrally constructed with the battery pack housing 12 or the battery pack housing housing housing.

[0021] The first interface 14 and the second interface 18 are complementary in their shape-locking connection with the first battery pack receiving interface 16 and the second battery pack receiving interface 20. In particular, the first battery pack receiving interface 16 and the second battery pack receiving interface 20 have two opposing L-shaped tracks 44a, 44b, 46a, 46b (see...). Figure 5 , Figure 6 The L-shaped track is fitted into the U-shaped profile of the first interface 14 or the second interface 18 (see...). Figure 3 , Figure 4 This allows for axial or translational insertion of the first battery pack receiving interface 16 or the second battery pack receiving interface 20 into the first interface 14 or the second interface 18. Axial fixation is ensured, in particular, by means of a connection 48 to the end face of the battery pack receiving compartment 12, for example, by a threaded connection.

[0022] The first battery pack receiving interface 16 or the second battery pack receiving interface 20 has a first battery pack receiving interface bracket 50a, 50b or a second battery pack receiving interface bracket 52a, 52b for supporting and / or threadedly connected to the end face of the battery pack receiving compartment 12. The bracket arm lengths 54, 56 of the first and second battery pack receiving interface brackets differ from each other, particularly in their extension dimensions perpendicular to the mirror symmetry plane 38. The bracket arm length 56 of the second battery pack receiving interface brackets 52a, 52b is shorter than the bracket arm length 54 of the first battery pack receiving interface brackets 50a, 50b.

[0023] The first interface 14, and especially the upper surfaces 58a, 58b of the guide rails 26a, 26b of the first interface 14, preferably defining a common abutment plane, form an abutment surface 60 for the second battery pack receiving interface 20, and especially the lower surface of the abutment surface of the second battery pack receiving interface (not shown here). Therefore, the second battery pack receiving interface 20 abuts against the first interface 14, especially against the upper surfaces 58a, 58b of the guide rails 26a, 26b, and especially against the preferably recessed lower surface. Therefore, the second battery pack interface 20 is held, especially by the second guide rails 28a, 28b of the second interface 18 and especially by abutting against the first interface 14. Therefore, the first interface 14, especially the guide rails 26a, 26b of the first interface 14, has a dual function, providing a holding or supporting function for the first battery pack receiving interface 16, and a supporting and abutment surface function for the second battery pack receiving interface 20.

[0024] Although the attached figures do not show the inserted battery pack (especially the 18V battery pack) fixed to the lawnmower robot 10, it is conceivable that the battery pack can be translatably accommodated in the first battery pack accommodating interface 16 or the second battery pack accommodating interface 20 via complementary shape-locking devices.
