Description

Technical Field

[0001] The present invention relates to a pantograph for roads, and more particularly to a pantograph slide structure for roads. Background Art

[0002] As the new century approaches, the world is facing the pressure of oil shortage and environmental protection. Energy and automotive technologies have once again undergone changes, and modern electrified roads have once again become an important technical direction in the new energy vehicle era.

[0003] During the driving process, an electric vehicle uses a pantograph to draw power from the power grid and directly transmits it to the motor to drive the electric vehicle, which can meet the long-distance operation requirements. It has high energy utilization efficiency, can achieve pantograph alignment charging, has a low overall cost, and there is no worry about the shortage of charging piles. Since the "standard electrified road solution" can significantly reduce the usage of lithium batteries, it is the ultimate development direction of new energy electric vehicles in the future and can realize a truly electrified road.

[0004] The existing solution uses a single slide, on which several carbon slides are distributed. There are insulating materials connecting between the carbon slides. When the slide contacts the catenary, it will inevitably slide between several carbon slides. The insulating parts will inevitably come into contact with the carbon powder generated by the friction between the carbon slides and the catenary, resulting in insufficient insulation distance and decreased insulation performance, which is likely to cause a short circuit between the positive and negative catenaries and easily lead to safety accidents. The above problems will also occur in rainy or snowy weather. In addition, there is a problem of unstable current collection when the catenary contacts the insulating part.

[0005] In view of this, the present invention is specifically proposed. Summary of the Invention

[0006] The purpose of the present invention is to provide a pantograph slide structure for roads to solve the above-mentioned technical problems existing in the prior art.

[0007] The purpose of the present invention is achieved through the following technical solutions:

[0008] The pantograph slide structure for roads of the present invention includes insulating brackets and carbon slides. A plurality of insulating brackets are arranged in parallel at a certain distance interval;

[0009] The carbon slides on adjacent insulating brackets are arranged in a staggered manner, and there is an overlapping part in the longitudinal projection;

[0010] The space between the carbon slides on adjacent insulating brackets is insulated, and each catenary continuously contacts the carbon slides on at least two insulating brackets during the transition between the carbon slides.

[0011] Compared with the prior art, for the pantograph carbon slide structure provided by the present invention, the insulation distance between carbon slides can be guaranteed, even in rainy and snowy weather, avoiding short circuits between positive and negative contact wires and improving safety. The carbon slides are staggeredly distributed and fixed on an insulation bracket on two or more slides. There is no insulation transition gap between adjacent staggered carbon slides, ensuring stable current collection when the contact wire transitions between carbon slides.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0019] First, the following explanations are given for the terms that may be used in this article:

[0020] The term "and / or" means that either one or both of the two can be achieved. For example, X and / or Y means that it includes both the case of "X" or "Y" and the three cases of "X and Y".

[0021] Descriptions with semantic meanings such as "include", "comprise", "contain", "have" or other similar ones should be interpreted as non-exclusive inclusion. For example: including a certain technical feature element (such as raw material, component, ingredient, carrier, dosage form, material, size, part, component, mechanism, device, step, process, method, reaction condition, processing condition, parameter, algorithm, signal, data, product or article, etc.) should be interpreted as not only including the clearly listed certain technical feature element, but also including other well-known technical feature elements in the art that are not clearly listed.

[0022] The term "consisting of" means excluding any technical feature elements not explicitly listed. If this term is used in a claim, the claim will be a closed - type claim, making it not contain technical feature elements other than those explicitly listed, except for the related conventional impurities. If this term only appears in a certain clause of a claim, then it only limits the elements explicitly listed in that clause, and the elements recorded in other clauses are not excluded from the overall claim.

[0023] Unless otherwise clearly stipulated or defined, terms such as "installed", "connected", "joined", "fixed", etc. should be understood in a broad sense. For example: it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in this text can be understood according to specific circumstances.

[0024] The orientation or positional relationship indicated by terms such as "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of description and simplification of the description, rather than explicitly or implicitly indicating that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, so it cannot be understood as a limitation to this text.

[0026] The pantograph slider structure for highways of the present invention includes insulating brackets and carbon sliders. A plurality of insulating brackets are arranged in parallel at a certain distance interval.

[0027] The plurality of carbon sliders on adjacent insulating brackets are arranged in a staggered manner, and there are overlapping parts in the longitudinal projection.

[0028] The space between the carbon sliders on adjacent insulating brackets is insulated, and each contact wire continuously contacts the carbon sliders on at least two insulating brackets when transitioning between the carbon sliders.

[0029] The insulating brackets are made of insulating materials.

[0030] The carbon skateboard includes carbon strips, which are bonded above the conductor bracket. The conductor bracket is provided with at least two built-in bolts, and the carbon skateboard is fixed on the insulating bracket through the built-in bolts and connected to the drainage cable.

[0032] In summary, in the pantograph skateboard structure of the embodiment of the present invention, the insulation distance between the carbon skateboards can be guaranteed, and it can also be guaranteed in rainy and snowy weather, avoiding short circuits between the positive and negative contact wires, and improving safety. The carbon skateboards are misaligned and distributed and fixed on the insulating brackets of two or more skateboards. There is no insulation transition gap between adjacent misaligned carbon skateboards, ensuring stable current collection when the contact wire transitions between the carbon skateboards.

[0033] In order to more clearly show the technical solutions provided by the present invention and the technical effects produced, the following will describe in detail the embodiments provided by the present invention with specific embodiments.

[0034] Embodiment 1

[0035] As Figures 1 to 4 shown:

[0036] The present invention uses two or more skateboards. The carbon skateboards are misaligned and distributed and fixed on the insulating brackets of two or more skateboards. The insulation effect is achieved through the spatial isolation between the skateboards, and the insulation problem between the carbon skateboards is well solved.

[0037] As Figure 1 shown, two skateboards are separated by a certain distance. Part 1 is the carbon skateboard, Part 2 is the insulating bracket, Part 3 is another insulating bracket, and Part 4 is the bow angle. The carbon skateboards are misaligned and distributed on the two insulating brackets. The carbon skateboards on the two skateboards ensure stable current collection when the contact wire transitions between the carbon skateboards. The contact wire contacts the mutually misaligned carbon skateboards on the two insulating brackets. The two energized carbon skateboards can well maintain the insulation distance. Even in rainy and snowy weather, the insulation distance is not greatly affected, and the insulation requirements can be well met, and there will be no short circuit between the positive and negative contact wires.

[0038] The electrical schematic diagram is as Figure 2 , when the positive and negative contact wires are placed on the two skateboards, they contact the two misaligned carbon skateboards. The current enters the vehicle motor through the cable and the diode. Using the one-way conductivity of the diode, the direction of the current input to the vehicle motor is ensured to be fixed.

[0039] The structure of the carbon skateboard 3 is as Figure 3 shown, and it is composed of a carbon strip 5, a conductor bracket 6, and a built-in bolt 7. The carbon strip is bonded to the conductor bracket, and the built-in bolt is used to fix the carbon skateboard on the insulating bracket and connect the cable for drainage.

[0040] The insulating bracket is as follows Figure 4 As shown, the grooved areas are used to fix the carbon sliding plate, and the depth and shape of the grooves fit the conductor brackets of the carbon sliding plate. The grooved areas at both ends are used to fix the bow angles.

[0041] The present invention uses two or more sliding plates, and a plurality of carbon sliding plates are staggeredly distributed and fixed on the insulating brackets of two or more sliding plates. The insulating distance between the carbon sliding plates can be guaranteed, avoiding short circuits between the positive and negative contact wire meshes, and improving safety. At the same time, the carbon sliding plates are staggeredly distributed and fixed on the insulating brackets of two or more sliding plates, and there is no insulating transition gap between adjacent staggered carbon sliding plates, which also ensures stable current collection when the contact wire transitions between the carbon sliding plates.

[0042] The insulating bracket is made of insulating material. Two or more insulating brackets can be used, or the two ends of two or more insulating brackets can be connected together to form one insulating bracket.

[0043] As described above, the above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims. The information disclosed in the background art part of this article is only intended to deepen the understanding of the overall background technology of the present invention, and should not be regarded as an admission or any form of suggestion that this information constitutes the prior art known to those skilled in the art.
