Description

Technical Field

[0001] This application relates to the field of vehicle technology, specifically to a steering gear, a steering gear assembly, and a vehicle. Background Technology

[0002] In the prior art, to prevent damage to the steering gear body from scrapes at the bottom of the vehicle, a steering gear protective structure is usually installed at the bottom of the vehicle. This protective structure can protect the steering gear body in the event of a scrape at the bottom of the vehicle.

[0003] However, most existing steering gear protection structures are installed on the frame at the front of the steering gear body. Due to the limitations of the frame structure, the protection structure cannot be adaptively adjusted according to the specific size and position of the steering gear body, thus limiting the protection range of the steering gear body and affecting the protection effect. Utility Model Content

[0004] In view of this, this application provides a steering gear, a steering gear assembly, and a carrier to solve the problem that existing protective structures have limited protection range for steering gears.

[0005] In a first aspect, this application provides a steering gear, including a housing and at least two protective member mounting structures, wherein the at least two protective member mounting structures are axially spaced on the outer wall of the housing, and each of the protective member mounting structures is adapted to be connected to a protective member.

[0006] Beneficial effects: A protective component mounting structure is provided on the steering gear housing. This structure allows the protective component to be mounted on the housing, thus establishing a direct connection between the protective component and the steering gear body. The protective component can be adaptively adjusted according to the specific size and location of the steering gear, thereby improving the protection effect on the steering gear body.

[0007] In one alternative embodiment, each of the protective component mounting structures includes a first mounting base and a second mounting base spaced apart along the circumferential direction of the housing.

[0008] Beneficial effects: By arranging the first and second mounting seats at intervals around the circumference of the shell, multi-point installation support of the protective components is achieved, thereby enhancing the installation strength of the protective components and improving the overall stability of the protective components.

[0009] In one alternative embodiment, along the height direction of the housing, the second mounting base is located below the first mounting base, and the protective mounting structure further includes a support arm disposed between the housing and the first mounting base, with both ends of the support arm connected to the housing and the first mounting base, respectively.

[0010] Beneficial effects: By placing the second mounting base below the first mounting base, and connecting the first mounting base to the housing via a support arm, the first and second mounting bases can form a staggered installation layout, which facilitates the installation of protective components, improves the installation strength of the protective components, ensures that the protective components remain fixed during a collision, and achieves effective protection for the steering gear.

[0011] In one optional embodiment, the support arm includes a plurality of connecting ribs and at least one reinforcing rib. The plurality of connecting ribs are spaced apart on the housing, and both ends of each connecting rib are connected to the housing and the first mounting base, respectively; at least one reinforcing rib is disposed between two adjacent connecting ribs and connected to the connecting ribs, and both ends of the reinforcing rib are connected to the housing and the first mounting base, respectively.

[0012] Beneficial effects: Multiple connecting ribs arranged at intervals form a distributed connection between the shell and the first mounting base, allowing the impact load to be distributed more evenly along the shell and avoiding stress concentration. Furthermore, reinforcing ribs are added between adjacent connecting ribs, and the cooperation between the reinforcing ribs and the connecting ribs enhances the bending stiffness of the support arm, effectively suppressing local deformation of the support arm when subjected to dynamic impacts from the protective components.

[0013] In an alternative embodiment, the steering gear further includes at least one first rib connected to the outer wall of the housing and extending axially along the housing, with one end of each first rib connected to the first mounting base and the support arm; and / or, at least one second rib connected to the outer wall of the housing and extending axially along the housing, with one end of each second rib connected to the second mounting base.

[0014] Beneficial effects: By adding a first rib between the first mounting base and the support arm and the housing, the connection strength between the first mounting base and the support arm and the housing can be improved. By adding a second rib between the second mounting base and the housing, the connection strength between the second mounting base and the housing can be improved, thereby improving the connection strength between the protective component and the housing, and achieving effective protection for the steering gear.

[0015] In one optional embodiment, a first weight-reducing groove is provided on the outer wall of the first mounting base, and a first reinforcing rib is provided in the first weight-reducing groove; and / or, a second weight-reducing groove is provided on the second mounting base, and a second reinforcing rib is provided in the second weight-reducing groove.

[0016] Beneficial effects: By setting a first weight-reducing groove on the first mounting base to remove material, the overall weight of the protective component mounting structure is effectively reduced. Simultaneously, a first reinforcing rib is added within the first weight-reducing groove, utilizing its supporting role to compensate for the strength loss caused by creating the first weight-reducing groove. Similarly, by setting a second weight-reducing groove on the second mounting base to remove material, the overall weight of the protective component mounting structure can be effectively reduced. Furthermore, a second reinforcing rib is added within the second weight-reducing groove, utilizing its supporting role to compensate for the strength loss caused by creating the second weight-reducing groove. The above arrangement satisfies the requirements of lightweight design while ensuring the mechanical properties of both the first and second mounting bases.

[0017] Secondly, this application provides a steering gear assembly, including the steering gear and protective component as described in any of the preceding claims. The protective component includes a protective part, which is detachably mounted on the protective component mounting structure; wherein, along the longitudinal direction of the vehicle, the protective part is located at the front lower part of the housing.

[0018] Beneficial effects: The spatial layout of the protective unit, located at the lower front of the housing, allows it to prioritize contact with obstacles in the event of a bottom scrape, forming a frontal protective barrier for the steering gear. Furthermore, by integrating the protective component directly onto the steering gear, its installation position can be flexibly adjusted according to the actual dimensions of the steering gear, enhancing its protective effect. In addition, the protective unit's detachable connection to the mounting structure ensures installation stability and facilitates maintenance and replacement, thereby reducing maintenance costs.

[0019] In one alternative embodiment, the protective component includes a connecting bracket detachably connected to the mounting structure of the protective component; the protective part is configured as a protective rod extending axially along the steering gear, and the protective rod is connected to the connecting bracket.

[0020] Beneficial effects: The protective bar extends axially along the steering gear, matching its coverage area with the length of the steering gear to form a continuous protective barrier. Furthermore, the connecting bracket, as an independent component, is detachably connected to the housing via the protective component mounting structure, allowing the entire protective component to be independently installed and removed. When the protective bar is damaged, there is no need to replace the steering gear; only the protective component needs to be replaced, thus significantly reducing maintenance costs.

[0021] In one optional embodiment, the protective rod is a hollow structure, and the inner cavity of the protective rod is provided with cross-arranged reinforcing ribs; and / or, the connecting bracket is configured as a C-shaped structure.

[0022] Beneficial effects: The protective rod features a hollow structure with reinforcing ribs inside, maintaining its external impact resistance while achieving a lightweight design and reducing the overall weight of the protective component. The C-shaped connecting bracket facilitates connection with the first and second mounting bases, and it also avoids stress concentration, allowing for a more even distribution of impact loads and improving the support strength of the protective rod.

[0023] Thirdly, this application provides a vehicle including the steering assembly described in any of the above claims.

[0024] Beneficial effects: By integrating a steering gear assembly with a specific spatial layout into the vehicle, direct adaptation between the protective components and the steering gear is achieved, allowing the protective components to be adaptively adjusted according to the specific size and position of the steering gear. The protective components are located at the lower front of the housing and are detachably connected to the housing, ensuring that they can prioritize contact with obstacles to form material isolation in the event of a scrape, and also facilitating subsequent replacement of the protective components, thus reducing vehicle maintenance costs.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0039] The following is combined with Figures 1 to 5 This describes an embodiment of the present application.

[0040] According to an embodiment of this application, in a first aspect, this application provides a steering gear, including a housing 1 and at least two protective member mounting structures 2, wherein the at least two protective member mounting structures 2 are axially spaced on the outer wall of the housing 1, and each protective member mounting structure 2 is adapted to be connected to a protective member 100.

[0041] First, it should be noted that, as Figure 1 , Figure 4 As shown, in this embodiment, the height direction Z represents the height of the vehicle, the front-to-back direction X represents the length of the vehicle, and the axial direction of the steering gear and housing 1 represents the width of the vehicle. Of course, those skilled in the art can adjust the specific directions indicated by the height direction Z and the front-to-back direction X according to actual needs.

[0042] In this embodiment, as Figure 1As shown, the housing 1, as the basic component supporting the internal transmission mechanism of the steering gear, can be formed into a hollow cylindrical structure through casting. The protective mounting structure 2 is configured to protrude from the surface of the housing 1, and is preferably integrally formed with the housing 1 through casting, thereby facilitating the overall manufacturing of the housing 1 and the protective mounting structure 2, and further improving the connection strength between the housing 1 and the protective mounting structure 2.

[0043] Multiple protective component mounting structures 2 are distributed at preset distances along the axial direction of the housing 1. By setting multiple protective component mounting structures 2, the protective component 100 is connected and supported, thereby improving the connection strength between the protective component 100 and the housing 1. The specific number of protective component mounting structures 2 can be adjusted according to actual needs.

[0044] With this configuration, a protective component mounting structure 2 is provided on the steering gear housing 1. This structure allows the protective component 100 to be mounted on the housing 1, establishing a direct connection between the protective component 100 and the steering gear body. Once the protective component 100 is fixed to the housing 1 via multiple mounting structures 2, the area covered by the protective component 100 is determined by the spacing between the outermost mounting structures 2 at both ends, allowing for adjustment of the protection range according to the steering gear dimensions. In the event of a bottom scrape, the protective component 100 preferentially contacts the obstacle and distributes the impact force to the housing 1 through the multiple mounting structures 2, thus preventing localized stress concentration.

[0045] Optionally, the aforementioned steering mechanism is applied to a vehicle, such as an automobile, construction machinery, or other ground-mounted mobile equipment.

[0046] In one embodiment, each protective component mounting structure 2 includes a first mounting base 21 and a second mounting base 22 spaced apart along the circumference of the housing 1.

[0047] In this embodiment, as Figure 1 , Figure 2 As shown, a first mounting seat 21 and a second mounting seat 22 are provided at intervals on the circumferential surface of the housing 1, which realizes multi-point installation support for the protective component 100, thereby enhancing the installation strength of the protective component 100 and improving the overall installation stability of the protective component 100.

[0048] When the protective component 100 is connected to the first mounting base 21 and the second mounting base 22, the protective component 100 forms a stable impact-resistant structure through the support of the first mounting base 21 and the second mounting base 22. When the vehicle collides at the bottom, the load on the protective component 100 can be transferred to different areas of the housing 1 through the first mounting base 21 and the second mounting base 22, thereby avoiding stress concentration.

[0049] Optionally, the first mounting base 21 and the second mounting base 22 can be arranged symmetrically or asymmetrically, forming complementary support areas through spatial differences. The circumferential distance between the first mounting base 21 and the second mounting base 22 can be adaptively adjusted according to the actual diameter of the housing 1.

[0050] Optionally, such as Figure 2 , Figure 3 As shown, the first mounting base 21 has a first mounting hole 211, and the second mounting base 22 has a second mounting hole 221. Bolts 106 can be inserted into both the first mounting hole 211 and the second mounting hole 221. By engaging the bolts 106 with the mounting holes, the protective component 100 can be conveniently and effectively fixed to the first mounting base 21 and the second mounting base 22, and the protective component 100 can be easily disassembled from the first mounting base 21 and the second mounting base 22.

[0051] Of course, in addition to the bolt connection method mentioned above, the protective component 100 can also be connected and fixed to the first mounting base 21 and the second mounting base 22 by means of snap-fit ​​connection, bonding or welding.

[0052] In one embodiment, along the height direction Z of the housing 1, the second mounting base 22 is located below the first mounting base 21, and the protective component mounting structure 2 also includes a support arm 23, which is disposed between the housing 1 and the first mounting base 21, with both ends of the support arm 23 connected to the housing 1 and the first mounting base 21 respectively.

[0053] In this embodiment, as Figure 3 , Figure 4 As shown, a support arm 23 is provided between the first mounting base 21 and the housing 1. The two ends of the support arm 23 are fixedly connected to the outer wall of the housing 1 and the first mounting base 21, respectively. When the protective member 100 is subjected to an impact from the bottom, the load is transmitted to the support arm 23 through the first mounting base 21. The support arm 23 can distribute the load to the axial and circumferential areas of the housing 1.

[0054] The second mounting base 22 is arranged below the first mounting base 21, which enables the first mounting base 21 and the second mounting base 22 to form a staggered installation layout in the vertical direction, thereby facilitating the installation of the protective component 100, making the load distribution of the protective component installation structure 2 more uniform, and improving the installation strength of the protective component 100, ensuring that the protective component 100 remains fixed during the collision, and achieving effective protection of the steering gear.

[0055] In one embodiment, the support arm 23 includes a plurality of connecting ribs 231 and at least one reinforcing rib 232. The plurality of connecting ribs 231 are arranged at intervals on the housing 1, and the two ends of each connecting rib 231 are respectively connected to the housing 1 and the first mounting base 21; at least one reinforcing rib 232 is disposed between two adjacent connecting ribs 231 and connected to the connecting ribs 231, and the two ends of the reinforcing rib 232 are respectively connected to the housing 1 and the first mounting base 21.

[0056] In this embodiment, as Figure 3 As shown, the connecting rib 231 serves as a longitudinal support member between the housing 1 and the first mounting base 21. Multiple connecting ribs 231 arranged at intervals form a distributed connection between the housing 1 and the first mounting base 21, allowing the load to be distributed relatively evenly along the housing 1 and avoiding stress concentration. Furthermore, a reinforcing rib 232 is added between two adjacent connecting ribs 231. The reinforcing rib 232 can suppress the mutual displacement between the connecting ribs 231, and the cooperation between the reinforcing rib 232 and the connecting rib 231 enhances the bending stiffness of the support arm 23. Therefore, when the support arm 23 is subjected to dynamic impact from the protective member 100, it can effectively suppress local deformation of the support arm 23.

[0057] In this embodiment, the supporting member formed by the connecting rib 231 and the reinforcing rib 232 not only ensures effective support for the first mounting base 21, but also reduces the overall weight of the supporting member, thereby achieving a lightweight design.

[0058] Optionally, such as Figure 3 As shown, multiple connecting ribs 231 are arranged at intervals along the axial direction of the housing 1, thereby forming a parallel support structure, so that the load from the first mounting base 21 is transmitted to the housing 1 through multiple independent paths. Of course, in addition to the arrangement of multiple connecting ribs 231 at intervals along the axial direction of the housing 1, multiple connecting ribs 231 can also be arranged at intervals along the circumference of the housing 1, which can also support the first mounting base 21.

[0059] In one embodiment, the steering gear further includes at least one first rib 3 connected to the outer wall of the housing 1 and extending axially along the housing 1, with one end of each first rib 3 connected to the first mounting base 21 and the support arm 23; and / or, at least one second rib 4 connected to the outer wall of the housing 1 and extending axially along the housing 1, with one end of each second rib 4 connected to the second mounting base 22.

[0060] In this embodiment, as Figure 3As shown, the first rib 3 is a plate-shaped reinforcing structure extending axially along the housing 1. Specifically, it can be integrally formed with the outer wall of the housing 1 using a casting process. The first rib 3 is fixed to the first mounting base 21 and the support arm 23. By adding the first rib 3 between the first mounting base 21 and the support arm 23 and the housing 1, the connection strength between the first mounting base 21 and the support arm 23 and the housing 1 can be improved. Similarly, the second rib 4 is a plate-shaped reinforcing structure extending axially along the housing 1. Specifically, it can be integrally formed with the outer wall of the housing 1 using a casting process. The second rib 4 is fixed to the second mounting base 22. By adding the second rib 4 between the second mounting base 22 and the housing 1, the connection strength between the second mounting base 22 and the housing 1 can be improved, thereby improving the connection strength between the protective component 100 and the housing 1, achieving effective protection for the steering gear.

[0061] With this configuration, when the protective component 100 is impacted by a bottom obstacle, the impact force is transmitted from the first mounting base 21 to the housing 1 via the support arm 23. At the same time, the first axially extending rib 3 disperses part of the load along the axial direction of the housing 1. The second rib 4 directly absorbs part of the load borne by the second mounting base 22, and the load is transmitted to the housing 1 more evenly through the axially extending plate-like structure, avoiding stress concentration in local areas.

[0062] Optionally, the axial extension length of the first rib 3 and the second rib 4 in the housing 1 can be adjusted according to actual needs.

[0063] In one embodiment, a first weight-reducing groove 24 is provided on the outer wall of the first mounting base 21, and a first reinforcing rib 25 is provided inside the first weight-reducing groove 24; and / or, a second weight-reducing groove 26 is provided on the second mounting base 22, and a second reinforcing rib 27 is provided inside the second weight-reducing groove 26.

[0064] In this embodiment, as Figure 2 , Figure 3 , Figure 4 As shown, the first weight-reducing groove 24 is a groove structure formed on the outer wall of the first mounting base 21. The first weight-reducing groove 24 is preferably located on the end face of the first mounting base 21 away from the support arm 23. The first reinforcing rib 25 is fixed inside the first weight-reducing groove 24 and protrudes from the bottom of the groove. By setting the first weight-reducing groove 24 on the first mounting base 21, material removal is achieved, effectively reducing the overall weight of the protective component mounting structure 2. At the same time, the first reinforcing rib 25 is added inside the first weight-reducing groove 24, and the supporting effect of the first reinforcing rib 25 compensates for the strength loss caused by setting the first weight-reducing groove 24.

[0065] The structural principle of the second weight-reducing groove 26 and the second reinforcing rib 27 is the same as described above. The second weight-reducing groove 26 is preferably located on the end face of the second mounting base 22 away from the housing 1. By setting the second weight-reducing groove 26 on the second mounting base 22, material removal can be achieved, which can also effectively reduce the overall weight of the protective component mounting structure 2. At the same time, the second reinforcing rib 27 is added in the second weight-reducing groove 26, and the supporting effect of the second reinforcing rib 27 is used to compensate for the strength loss caused by opening the second weight-reducing groove 26.

[0066] Of course, in addition to the above-mentioned opening positions, the first weight reduction groove 24 and the second weight reduction groove 26 can also be adaptively adjusted according to the actual force distribution of the first mounting base 21 and the second mounting base 22.

[0067] With this configuration, by opening the first weight-reducing groove 24 and the second weight-reducing groove 26, the amount of material used can be reduced, the requirements for lightweight design can be met, and the mechanical properties of the first mounting base 21 and the second mounting base 22 can be guaranteed.

[0068] Optionally, the first weight-reducing groove 24 can be integrally formed with the first mounting base 21 using a casting process, and the second weight-reducing groove 26 can be integrally formed with the second mounting base 22 using a casting process. Alternatively, it can be manufactured by subsequent machining.

[0069] Secondly, this application provides a steering gear assembly, including the steering gear and protective member 100 as described above. The protective member 100 includes a protective part, which is detachably mounted on the protective member mounting structure 2; wherein, along the longitudinal direction X of the vehicle, the protective part is located at the front lower part of the housing 1.

[0070] In this embodiment, as Figure 4 As shown, the protective component mounting structure 2 includes a first mounting base 21 and a second mounting base 22. The protective component 100 is detachably mounted on the first mounting base 21 and the second mounting base 22. The spatial layout of the protective part located in the lower front of the housing 1 allows the protective part to make priority contact with the obstacle when the bottom of the vehicle is scraped, forming a front protective barrier for the steering gear. Furthermore, by directly integrating the protective component 100 onto the steering gear, the installation position of the protective component 100 can be flexibly adjusted according to the actual size of the steering gear, thereby improving the protection effect on the steering gear.

[0071] In addition, the protective part is connected to the protective component mounting structure 2 in a detachable manner, which not only ensures the installation stability of the protective part but also facilitates the maintenance and replacement of the protective part, thereby reducing maintenance costs.

[0072] Furthermore, along the front-rear direction X of the vehicle, the protective part is located at the lower front of the housing 1, which can not only protect the steering gear located behind the protective part, but also protect components such as the battery located behind the steering gear.

[0073] In one embodiment, the protective member 100 includes a connecting bracket 101, which is detachably connected to the protective member mounting structure 2; the protective part is configured as a protective rod 102, which extends along the axial direction of the steering gear and is connected to the connecting bracket 101.

[0074] In this embodiment, as Figure 1 , Figure 5 As shown, the connecting bracket 101 is directly connected to the first mounting base 21 and the second mounting base 22. The protective part adopts a protective rod 102, which is mounted on the connecting bracket 101 and extends along the steering gear axis, so that the coverage of the protective rod 102 matches the length direction of the steering gear, thereby forming a continuous protective barrier. Furthermore, the connecting bracket 101, as an independent component, is detachably connected to the housing 1 through the protective component mounting structure 2, allowing the protective component 100 to be independently disassembled and assembled. When the protective rod 102 is damaged, it is not necessary to replace the steering gear; only the protective component 100 needs to be replaced, thus significantly reducing maintenance costs.

[0075] Optionally, the guard rod 102 and the connecting bracket 101 can be detachably connected by bolts or clips. This way, if the guard rod 102 is damaged due to a collision, only the guard rod 102 needs to be replaced to complete the repair, further reducing maintenance costs.

[0076] In one embodiment, the protective rod 102 is a hollow structure, and the inner cavity of the protective rod 102 is provided with cross-arranged reinforcing ribs 103; and / or, the connecting bracket 101 is configured as a C-shaped structure.

[0077] In this embodiment, as Figure 1 , Figure 5 As shown, the protective rod 102 is configured as a tubular shape with an internal closed cavity, which can be achieved by extrusion molding or welding of a metal square tube. Reinforcing ribs 103 are fixed in a diagonal pattern within the inner cavity of the protective rod 102. These reinforcing ribs 103 enhance the strength of the protective rod 102, maintaining the integrity of its external contour and reducing material usage while preserving its external impact resistance, thereby reducing the overall weight of the protective component 100.

[0078] In this embodiment, as Figure 5 As shown, the connecting bracket 101 adopts a C-shaped structure with an opening. The two ends of the C-shaped connecting bracket 101 are connected to the first mounting base 21 and the second mounting base 22 respectively, thereby avoiding stress concentration, distributing the load more evenly, and improving the support strength of the protective rod 102.

[0079] In one specific implementation, such as Figure 5As shown, the connecting bracket 101 includes two first connecting sections 1011 and a second connecting section 1012 disposed between the two first connecting sections 1011. Both ends of the second connecting section 1012 are connected to the two first connecting sections 1011 respectively. The two first connecting sections 1011 are bent relative to the second connecting section 1012, and the two first connecting sections 1011 correspond to and are connected to the first mounting base 21 and the second mounting base 22 respectively. The protective rod 102 is fixed to the second connecting section 1012. Thus, the two first connecting sections 1011 facilitate the connection of the connecting bracket 101 to the first mounting base 21 and the second mounting base 22.

[0080] Optionally, such as Figure 1 , Figure 5 As shown, bolt holes are respectively provided on the two first connecting sections 1011, and bolts 106 are inserted into the bolt holes. The end of one bolt 106 passes through the first mounting hole 211 on the first mounting base 21, and the end of the other bolt 106 passes through the second mounting hole 221 on the second mounting base 22. In this way, the connecting bracket 101 is connected and fixed to the steering gear by the bolts 106, and the connecting bracket 101 and the steering gear can be easily disassembled.

[0081] Furthermore, such as Figure 4 As shown, the length of bolt 106 is greater than the length of the first mounting hole 211 and the second mounting hole 221. The portion of bolt 106 exposed in the first mounting hole 211 and the second mounting hole 221 is connected and fixed to the vehicle. In this way, bolt 106 can not only connect and fix the connecting bracket 101 to the steering gear, but also fix the steering gear assembly to the vehicle.

[0082] Optionally, such as Figure 5 As shown, the connecting bracket 101 is also provided with a flange 104, which can further enhance the strength of the connecting bracket 101 and improve the protection effect on the steering gear.

[0083] Optionally, such as Figure 5 As shown, a third reinforcing rib 105 is also provided on the connecting bracket 101. The third reinforcing rib 105 can further enhance the strength of the connecting bracket 101 and improve the protection effect on the steering gear.

[0084] Thirdly, this application provides a vehicle including the steering assembly described in any of the above claims.

[0085] In this embodiment, by integrating a steering gear assembly with a specific spatial layout into the vehicle, direct adaptation between the protective component 100 and the steering gear is achieved, allowing the protective component 100 to be adaptively adjusted according to the specific size and position of the steering gear. The protective component 100 is located at the lower front of the housing 1 and is detachably connected to the housing 1, enabling it to prioritize contact with obstacles to form physical isolation in the event of a scrape, and facilitating subsequent replacement of the protective component 100, thus reducing vehicle maintenance costs.

[0086] Alternatively, the aforementioned vehicles may be automobiles, construction machinery, or other ground-based mobile equipment, or they may be low-altitude aircraft.

[0087] Although embodiments of this application have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of this application, and all such modifications and variations fall within the scope defined by the appended claims.
