Description

Technical Field

[0001] The present invention relates to providing power to vehicles by means of electric road tracks, and more specifically to a housing for a sunken electric road track, a sunken electric road track, and a method for arranging a sunken electric road track along a road. Background Technology

[0002] Electric vehicles are becoming increasingly common as traditional internal combustion engines are being replaced or combined with electric motors to reduce reliance on fossil fuels for transportation. However, ongoing efforts are underway to provide the necessary infrastructure to match the current service levels of internal combustion engine-powered vehicles.

[0003] For example, refueling a gasoline or diesel-powered vehicle takes only a few minutes, while charging the battery of a corresponding electric vehicle may take 40 or 50 minutes, depending on the battery and the capacity of the charging station. Charging stations are also not as common as regular gas stations.

[0004] However, to avoid having to stop electric vehicles to charge, various types of on-the-go charging methods have been developed. Providing power to a vehicle while it is moving not only offers the benefit of increased range but also allows for a reduction in battery capacity and thus, a decrease in vehicle weight.

[0005] One technology involves providing overhead conductors along the road from which vehicles can collect electricity. This solution is typically only applicable to one type of vehicle, most commonly heavy-duty freight vehicles or buses.

[0006] Another technology is electric road tracks, which are attached to the road surface and from which vehicles can collect electricity via conduction or induction. Electric road tracks offer many advantages over overhead power conductors and are more versatile, as they can be used with virtually any vehicle. However, electric road tracks are technically challenging because they are susceptible to wear and tear from vehicles, road dirt, and pose numerous safety concerns due to pedestrian accessibility. Summary of the Invention

[0007] In view of the above statements, the object of the present invention is to provide a housing for a sunken electric road track, a sunken electric road track, and a method for arranging the sunken electric road track in a groove in a road, thereby alleviating some of the problems of prior art solutions.

[0008] To achieve the foregoing objectives and at least one of other objectives that are apparent from the following description, a housing having the features defined in the following paragraph is provided in accordance with the teachings herein. Preferred embodiments of the device will become apparent from the following detailed description.

[0009] More specifically, in a first aspect, a housing for a sunken electric road track configured to conductively supply power to a vehicle is provided. The housing includes: a base plate extending longitudinally; opposing sidewalls projecting from the base plate and extending longitudinally; and opposing lateral flanges extending longitudinally to form lateral protrusions for anchoring the housing in a fixing material for securing the housing in a recess in the roadway. The housing provides a robust foundation and anchors the sunken electric road track to the roadway by providing the lateral flanges.

[0010] The opposing sidewalls may each include a lateral step extending longitudinally, such that the upper portion of the respective sidewall is laterally displaced outward relative to the bottom portion of the respective sidewall. The lateral steps provide support for a contact line structure configured to be arranged within the housing, which may have corresponding lateral flanges arranged in the space formed by the lateral steps in the opposing sidewalls. Furthermore, the lateral steps provide a hollow space between the opposing lateral flanges and the lateral steps, which can be filled with a fixing material, thus providing additional strength for the housing's fixation within the recess.

[0011] In a second aspect, a sunken electric roadway is provided, configured to provide power to a vehicle in a conductive manner. The sunken electric roadway includes: a housing according to the first aspect, extending along the sunken electric roadway and configured to be disposed in a recess formed in a roadway; a contact wire structure extending along the housing, through which a power current collector of the vehicle is configured to draw power conductively from the sunken electric roadway, the contact wire structure being disposed within the housing; and a plurality of clamps configured to clamp the contact wire structure to the housing to form a plurality of friction joints between the housing and the contact wire structure. The sunken electric roadway provides that it can be arranged flush with the top surface of the roadway, and therefore will not pose any obstruction to, for example, snowplows or other vehicles. The arrangement of the housing being fixed in a recess in the roadway and the individual contact wire structures being clamped to the housing facilitates maintenance and assembly of the sunken electric roadway, wherein the contact wire structures contain electronics for power transmission. For example, a broken contact wire structure can be easily released by removing the clamps, after which the contact wire structure can be lifted from the housing, which can then accommodate a new or repaired contact wire structure, thus allowing for rapid repair and reducing downtime. Furthermore, the friction joint between the contact wire structure and the housing allows for a certain degree of relative movement in the longitudinal direction, which is advantageous because the two components may be affected differently by temperature-related elongation, for example. Additionally, each housing can include more than one contact wire structure.

[0012] Multiple housings can be arranged one after another along the longitudinal direction of the sunken motorized track. The sunken motorized track may further include drainage pipes disposed beneath the base plates of the housings, the drainage pipes including inlets at joints between the housings. Therefore, water entering the sunken motorized track can be collected at the joints, and thereby discharged to a desired drainage outlet point via the drainage pipes.

[0013] The sunken electric road track may further include a fixing material that fills the space between the housing and a groove formed in the roadway, such that the housing is fixedly arranged in the groove.

[0014] The fixing material may include: a lower portion that fills the space between the bottom plate of the housing and the bottom of the groove and around the opposite lateral flange of the housing; and an upper portion that fills the space between the corresponding opposite sidewall of the housing and the corresponding sidewall of the groove, wherein the upper portion is arranged above the lower portion.

[0015] The composition of the stationary material in the upper part can differ from that in the lower part. This allows the stationary material to be adapted to the different environments experienced by the upper and lower parts. For example, different compositions of the upper part can be selected for environments with expected extremely high / low ambient temperatures.

[0016] The composition of the fixing material in the upper section can be more flexible than that in the lower section. This greater flexibility provides an improved seal to prevent water from entering the recess or the space between the fixing material and the housing. Furthermore, the flexibility of the upper section helps the sunken electric road track withstand wear and tear caused by vehicles traveling over / on it.

[0017] The submerged motor may further include an electrical insulation layer disposed between the housing and the contact wire structure. The electrical insulation layer reduces the risk of current flowing from the contact wire structure to the housing.

[0018] In a third aspect, a method is provided for arranging a sunken electric road track along a road. The method includes arranging the housing of the sunken electric road track in a recess formed in the roadway, such that a space is formed between the bottom plate of the housing and the bottom of the recess, and between the opposite sidewall of the housing and the corresponding sidewall of the recess; filling the space with a fixing material.

[0019] Filling the space with a fixing substance may include filling the lower portion with a first component of the fixing substance, thereby filling the space between the bottom plate of the housing and the bottom of the recess, as well as the space around the opposing lateral flanges, which extend longitudinally to form lateral protrusions for anchoring the housing; and filling the upper portion with a second component of the fixing substance, thereby filling the space between the corresponding opposing sidewalls of the housing and the corresponding sidewalls of the recess, wherein the upper portion is arranged above the lower portion, and wherein the second component of the fixing substance in the upper portion differs from the first component of the fixing substance in the lower portion. When the lower portion of the fixing substance is above and around the opposing lateral flanges of the housing, it provides robust fixation of the housing in the recess, while the upper portion of the fixing substance may have a composition suitable for the current environment in which a sunken electric road track is arranged, and, for example, reduces the risk of water seepage into the recess.

[0020] The method may further include recessing the contact wire structure of the electric road track inside the housing, configuring the vehicle's power collector to draw power from the recessed electric road track via the contact wire structure in a conductive manner; and using multiple clamps to clamp the contact wire structure onto the housing to form multiple friction joints between the housing and the contact wire structure.

[0021] The method may further include arranging an electrical insulating layer between the housing and the contact wire structure.

[0022] The method may further include: arranging multiple housings one after another along the longitudinal direction of the sunken electric road track; and arranging drainage pipes below the base plates of the multiple housings, the drainage pipes including inlets arranged at joints between the multiple housings.

Unless otherwise expressly stated, all references to “an / a / the [element, device, component, apparatus, step, etc.]” ​​are openly interpreted as referring to at least one instance of said element, device, component, apparatus, step, etc. Unless expressly stated otherwise, the steps of any method disclosed herein are not necessarily to be performed in the exact order disclosed.

[0035] The invention will now be described more fully with reference to the accompanying drawings, in which presently preferred embodiments of the invention are illustrated. However, the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to achieve thoroughness and completeness and to fully convey the scope of the invention to those skilled in the art.

[0036] Figure 1 A sunken electric road track 10 is disclosed, which is configured to provide power to a vehicle 20 in a conductive manner. The vehicle 20 is shown as an automobile, but the teachings herein are also applicable to electric road tracks for other vehicles, such as trucks, buses, etc. The sunken electric road track 10 is considered to be an electric road track configured such that it is substantially flush with the surrounding surface of the roadway 40 to which it is attached.

[0037] Vehicle 20 may be equipped with one or more power collectors 22; three are shown, but other numbers of power collectors 22 are also possible. The power collectors 22 are configured to contact the sunken electric road track 10, more specifically, the contact line structure 200 of the sunken electric road track. Figure 5 (As shown in the diagram) Contact. The power current collector 22 can be arranged on the underside 24 of the vehicle 20.

[0038] The sunken electric road track 10 includes a housing 100, which is in Figure 2 The diagram is shown in cross-sectional view. The housing 100 is configured to accommodate the contact wire structure 200, such that the contact wire structure 200 can be easily removed from the housing 100, for example, for maintenance or replacement. More than one contact wire structure 200 may be arranged in each housing 100.

[0039] The housing 100 may be made of corrosion-resistant metal or corrosion-resistant metal alloy, such as aluminum, stainless steel, etc. Other materials, such as polymer materials and composite materials, are also considered. The housing 100 is preferably formed as a single piece, for example, in an extrusion manufacturing process. The housing 100 is configured to be arranged in a recess 42 formed in the carriageway 40. Figures 6 to 8 (as shown in the diagram). The housing 100 includes a base plate 102 extending in a longitudinal direction L, which extends along the length of the housing 100 and the driveway 40.

[0040] The housing 100 further includes opposing sidewalls 104 that project upwards from the base plate 102 and extend in the longitudinal direction L. Opposing lateral flanges 106 are also provided on the housing 100, extending in the longitudinal direction L and forming lateral protrusions to anchor the housing 100 in a fixing material 30 for securing the housing 100 in a recess 42 of the driveway 40. The height of the opposing lateral flanges 106 can be between 3 mm and 8 mm, preferably about 5 mm. Furthermore, the opposing lateral flanges 106 can laterally protrude 5 mm to 15 mm, preferably about 10 mm, from the bottom portion 110 of the corresponding opposing sidewall 104. The bottom portion 110 of each opposing sidewall 104 is the portion adjacent to and connected to the base plate 102.

[0041] The opposite lateral flange 106 can be configured to project laterally beyond the corresponding upper portion 108 of the opposite sidewall 104. The opposite lateral flange 106 arranged in the fixing material 30 provides a secure and robust connection for securing the housing 100 in the recess 42 in the driveway 40.

[0042] like Figure 2 As shown, the opposing sidewalls 104 may each include a lateral step 112 extending in the longitudinal direction L, such that the upper portion 108 of the respective sidewall 104 is laterally displaced outward relative to the bottom portion 110 of the respective sidewall 104. The lateral step 112 may be formed as a support surface providing vertical support for the contact wire structure 200, which may be provided with corresponding opposing lateral flanges 202 configured to directly or indirectly abut against the lateral step 112. In this case, an indirect example is an electrical insulation layer 70 disposed on the contact wire structure 200.

[0043] Now go to Figures 3 to 5 The illustration shows perspective views of corresponding embodiments of the housing 100, clamp 50, and contact line structure 200. Figure 3 The image shows a section of the housing 100. The housing 100 may be provided with a plurality of recesses 114, each recess being configured to receive a corresponding clamp 50.

[0044] The clamp 50 is configured to clamp the contact wire structure 200 onto the housing 100 to form multiple friction joints between the housing 100 and the contact wire structure 200. Each friction joint is robust enough to hold the contact wire structure 200 in place within the housing 100, but allows for a degree of relative movement of the contact wire structure 200 relative to the housing 100 in the longitudinal direction L. Due to temperature variations, the contact wire structure 200 (which forms the housing for holding the electronic components used to transmit electricity from the sunken electric road track 10 to the vehicle 20) may be more prone to elongation / expansion than the housing 100, as the contact wire structure is exposed to the environment while the housing 100 is arranged in the recess 42 and thus subjected to different temperatures. The friction joints formed by the clamp 50 will allow for accommodating this relative movement / elongation / expansion between the contact wire structure 200 and the housing 100.

[0045] The clamp 50 may include a body portion 52 configured to be disposed in a recess 114, which is formed in an upper portion 108 of an opposite sidewall 104. The clamp 50 may be configured to be attached to the recess 114, for example, by means of one or more suitable fasteners such as screws.

[0046] However, the clamp 50 may also be implemented in other forms and attached to a housing 100 that does not have a recess 114. For example, a flat clamp 50 is envisioned that is attached to the upper portion 108 of each opposite sidewall 104 and configured to clamp the contact line structure 200 to the housing 100.

[0047] Alternatively, the clamp 50 can be configured to attach to the housing 100 on the lateral step 112 inside the upper portion 108 of each opposite sidewall 104, without requiring any recess 114 to be formed in the housing 100 to accommodate the clamp 50.

[0048] The contact wire structure 200 may have multiple recesses 208, and corresponding clamps 50 are configured to engage with the recesses to clamp the contact wire structure 200 onto the housing 100. Each clamp may have a lateral protrusion 54, which is configured to be disposed in a corresponding recess 208 in the contact wire structure 200. To allow the contact wire structure 200 to move relative to the housing 100 in the longitudinal direction, the longitudinal extension of the recesses 208 in the contact wire structure 200 in the longitudinal direction L may be greater than the longitudinal extension of the lateral protrusion 54 on each clamp 50.

[0049] The clamp 50 is preferably made of a non-conductive material, such as a polymer material, to avoid conductivity from the contact wire structure 200 to the housing 100.

[0050] Although only two recesses 114 and 208 are shown in the housing 100 and the contact line structure 200 respectively, it should be understood that multiple recesses 114 and 208 may be formed along the length of the housing 100 and the contact line structure 200 respectively.

[0051] The contact wire structure 200, configured to accommodate electronic components for transmitting power to the vehicle 20, as described above, may include one or more channels 212. Channels 212 may be configured to hold electrical conductors, such as copper conductors or other electrical components. Furthermore, the contact wire structure 200 may include recesses 210 extending in the longitudinal direction L, into which multiple segments of the contact wire (not shown) may be arranged, from which a power current collector 22 of the vehicle 20 is configured to draw power.

[0052] Preferably, the contact line structure 200 is made of the same material as the housing 100, i.e., a corrosion-resistant metal or corrosion-resistant metal alloy, such as aluminum, stainless steel, etc. Other materials, such as polymer materials and composite materials, are also considered. The contact line structure 200 is preferably formed as a single piece, for example, during an extrusion manufacturing process.

[0053] The upper surface 206 of the contact wire structure 200 is configured to be substantially flush with the surface of the surrounding carriageway 40. The bottom surface 204 of the contact wire structure 200 is configured to directly or indirectly abut against the base plate 102 of the housing 100.

[0054] Now go to Figure 6 The image shows a cross-sectional view of the sunken electric road track 10 when arranged in a recess 42 within the carriageway 40. (See image for details.) Figure 6 As shown, the groove 42 can be larger than the housing 100. This helps to fill the space 44 between the groove 42 and the housing 100 by filling the fixing material 30, which is designed to surround the outside of the housing 100.

[0055] Preferably, the width of the groove 42 is 2 cm to 5 cm, which is greater than the width of the housing 100. The depth of the groove 42 is preferably 1 cm to 2 cm, which is deeper than the corresponding height of the housing 100.

[0056] The fixing substance 30 is preferably an asphalt fixing substance that can be liquefied (e.g., by heating) so that it can be poured into the groove 42, where it can cool and settle around the housing 100, thereby fixing the housing in place in the groove 42.

[0057] The fixing material 30 may include a lower portion 32 that fills the space between the bottom plate 102 of the housing 100 and the bottom 46 of the groove 42, as well as the lower space 44a surrounding the opposite lateral flange 106 of the housing 100.

[0058] The fixing material 30 may further include an upper portion 34 that fills the upper space 44b between the corresponding opposite sidewall 104 of the housing 100 and the corresponding sidewall 48 of the recess 42. The upper portion 34 may constitute the uppermost 30 mm to 10 mm of the fixing material 30, preferably about 20 mm.

[0059] The composition of the fixing material 30 in the upper portion 34 may differ from that in the lower portion 32, preferably making the fixing material 30 in the upper portion 34 more flexible and elastic than that in the lower portion 32. The more flexible upper portion 34 helps accommodate movement within the sunken motorized track 10 due to thermal expansion / elongation and reduces the risk of water entering the recess 42. The composition of the fixing material 30 in the upper portion 34 can further adapt to the environment in which the sunken motorized track 10 is arranged.

[0060] Multiple housings 100 can be arranged one after another along the longitudinal direction L of the sunken electric road track 10, for example, in a long recess 42 formed in the roadway 40. Figure 7 As shown, the sunken motorized road track 10 may include drainage pipes 60 disposed below the base plates 102 of multiple housings 100. The drainage pipes 60 may be silicone tubes formed into the anchor material 30 below the base plates 102 of the housings 100. The drainage pipes 60 are configured to drain excess water that may reach the housings 100, the contact line structure 200, or the lower space 44a below the housings 100. Figure 9 As shown, for this purpose, the drain pipe 60 may include an inlet 62 arranged at a joint 12 between the plurality of housings 100 to collect water and at a location from which water can be discharged by means of the drain pipe 60. Thus, water entering the sunken motor track 10 is directed to the joint 12 between the plurality of housings 100 or to one end of the sunken motor track 10 from which water can enter the drain pipe 60.

[0061] Therefore, the drainage pipe 60 may also include one or more outlets through which water can be discharged, for example, into a storm drain.

[0062] In addition, such as Figure 8 As shown, the electrical insulation layer 70 can be disposed between the housing 100 and the contact wire structure 200. The electrical insulation layer 70 can be formed of a suitable electrical insulating material, preferably a flexible and durable material. For example, the electrical insulation layer can be formed of elastomers and / or polymer materials such as rubber and silicone.

[0063] The electrical insulation layer 70 provides electrical isolation between the housing 100 and the contact wire structure 200.

[0064] Now go to Figures 10a to 10d It illustrates steps 1002, 1004, 1004a, and 1004b of a method 1000 for arranging a sunken electric road track 10 along a road. Figure 10a The diagram shows the housing 100 of a sunken electric road track 10 arranged 1002 in a recess 42 formed in a roadway 40. The housing 100 is arranged 1002 such that a space 44 is formed between the bottom plate 102 of the housing 100 and the bottom 46 of the recess 42, and between the opposite sidewall 104 of the housing 100 and the corresponding sidewall 48 of the recess 42. For this purpose, one or more retainers (not shown) may be provided to support and suspend the housing 100 in the desired position within the recess 42.

[0065] Once the housing 100 is in its desired position, method 1000 further includes filling space 44 of 1004 with a fixing substance 30, which in Figure 10b As shown in the diagram. Preferably, the asphalt fixing material 30 is heated to liquefy it. Thereafter, the fixing material can be poured into the space 44 in the groove 42 until it completely fills the space 44 and is flush with the top surface of the driveway 40. The fixing material 30 will then cool and solidify, thereby securing the housing 100 in place and allowing the retainer to be removed.

[0066] like Figure 10c and Figure 10d As shown, the fixed substance 30 may include a lower portion 32 and an upper portion 34. For example... Figure 10cAs shown, the filling step 1004 may therefore include filling the lower portion 32 of the housing 100 with 1004a, thereby filling the space 44a between the bottom plate 102 of the housing 100 and the bottom 46 of the recess 42, and around the opposite lateral flange 106 of the housing 100. Optionally, this allows the lower portion 32 of the fixing material 30 to at least partially cool or solidify, after which the method 1000 may further include filling the upper portion 34 of the housing 100 with 1004a, thereby filling the space 44b between the corresponding opposite sidewall 104 of the housing 100 and the corresponding sidewall 48 of the recess 42. The upper portion 34 of the fixing material 30 may therefore be provided with different material properties than the lower portion 32, which may be desirable since the upper and lower portions serve different purposes to some extent. The lower portion 32 provides most of the strength for the bond between the housing 100 and the recess 42, and should therefore have a composition that makes the fixing material 30 therein relatively rigid and robust. The upper portion 34 is subject to weather and wear from vehicles traveling on the road, and therefore may include a retaining material 30 composed of a more flexible material, thereby providing better waterproof sealing and allowing greater mobility without release from the recess 42. The upper portion 34 is preferably configured to be substantially flush with the top surface around the driveway 40.

[0067] Additionally, method 1000 may further include arranging the drain pipe 60 in the recess 42, below the bottom plate 102 of the housing 100, such as... Figure 7 and Figure 9 As shown in the document.

[0068] Method 1000 may further include arranging a contact wire structure 200 within the housing 100, the contact wire structure 200 optionally having a pre-formed electrical insulation layer 70, such as... Figure 8 As shown, the contact wire structure 200 can then be clamped onto the housing 100 by means of a plurality of clamps 50, thereby forming a plurality of friction joints between the contact wire structure 200 and the housing 100.

[0069] It should be understood that the present invention is not limited to the embodiments shown. Therefore, various modifications and variations are contemplated within the scope of the present invention, and thus the scope of the present invention is defined only by the appended claims.
