Abstract
Description
Technical Field
[0001] This utility model relates to the field of vehicle technology, specifically to a vehicle and its front cover assembly. Background Technology
[0002] For traditional gasoline vehicles, range-extended vehicles, and other hybrid vehicles, the front compartment is primarily used to house the engine, so a front trunk is typically not provided. In this case, since the hood is rarely opened and used infrequently, vehicles equipped with an engine usually do not need to consider anti-pinch features for the hood during opening and closing.
[0003] As automobiles transition towards electrification, the front trunk is increasingly being used because there's no longer a need to reserve installation space for the engine in the front compartment. Due to the greater flexibility of the front trunk, the hood is being opened much more frequently compared to the traditional engine-mounted configuration. Currently, although electric vehicles are equipped with a front trunk structure, the development of the hood still tends to neglect anti-pinch functionality. However, given the functional shift, improving the safety of opening and closing the hood is essential. Consequently, the user experience of opening / closing the hood is becoming increasingly important. Utility Model Content
[0004] To address at least some and / or at least partially the aforementioned technical problems, this utility model is proposed. Specifically, it addresses how to implement an anti-pinch function for the front cover, including the front trunk, to enhance the safety experience for drivers and passengers when opening and closing the front cover.
[0005] In a first aspect, the present invention provides a front cover assembly for a vehicle, the vehicle including a front compartment, the front cover assembly including: a front cover disposed in the front compartment in an openable manner, the front cover having a gap area between the front compartment and the front compartment; and an anti-pinch portion including a plurality of anti-pinch mechanisms; the plurality of anti-pinch mechanisms being disposed in different portions of the gap area.
[0006] This configuration allows for the implementation of anti-pinch functionality in the front cover assembly through a combination of multiple anti-pinch mechanisms, thereby enhancing the user's safety experience when closing the front cover.
[0007] The phrase "multiple anti-pinch mechanisms are configured in different parts of the gap area" should be understood as follows: functionally, the anti-pinch mechanism can achieve anti-pinch function in the corresponding part of the gap area. Spatially, it can be set in the corresponding part of the gap area, or it can be set in other locations.
[0008] It is understood that those skilled in the art can determine the structural form, number, and specific method of achieving the anti-pinch function of the anti-pinch mechanism according to actual needs. For example, the anti-pinch mechanism may include two or more, and the structural form and anti-pinch principle of different anti-pinch mechanisms may be the same or different. Taking the gap area as roughly an annular area as an example, the local length of the gap area corresponding to multiple anti-pinch mechanisms may be the same or different.
[0009] In one possible implementation of the aforementioned vehicle hood assembly, the hood is rotatably disposed on the front compartment, thus giving the hood assembly a pivot side and a free side disposed opposite to each other. The gap area includes a first gap area near the pivot side and a second gap area near the free side. The anti-pinch portion includes: a first anti-pinch mechanism including an anti-pinch structure disposed in at least a portion of the first gap area; and a second anti-pinch mechanism disposed in at least a portion of the second gap area.
[0010] This configuration allows the front cover to achieve its anti-pinch function through the combination of two anti-pinch mechanisms.
[0011] It should be noted that the terms "pivoting side" and "free side" should be understood as follows: If the hood assembly can be pivoted (in a rotatable manner) in the front compartment via a structure / mechanism that allows rotation, such as a rotation, hinge / hing, or rotating module, the side of the hood assembly corresponding to or close to the connection position can be called the pivoting side, and the position roughly opposite the pivoting side can be called the free side. For example, the side of the hood assembly closer to the front (along the vehicle length) is the free side, and the side closer to the rear is the pivoting side.
[0012] It is understood that those skilled in the art can determine the configuration, specific length, proportional relationship, and arrangement of the first and second gap areas according to actual needs. For example, their lengths (layout ranges) can be the same or different. The length of the first / second gap area can be described by the chord length (straight-line distance between the start and end points) or arc length (length of the anti-pinch structure between the start and end points) of the projection of the first / second gap area onto the horizontal plane. The anti-pinch structures corresponding to the first / second gap area can be arranged in a roughly symmetrical or asymmetrical manner.
[0013] It is understood that those skilled in the art can determine the structural form, number, and placement of the anti-pinch structure at the corresponding position in the first gap area according to actual needs. For example, the anti-pinch structure may include, but is not limited to, a sealing ring, a negative pressure adsorption structure, a buffer structure, or a reasonable clearance space provided at the user's hand position. The first anti-pinch mechanism may include one or more anti-pinch structures. In the case of multiple anti-pinch structures, these structures may be identical or different, and adjacent anti-pinch structures may be spaced apart, connected to each other, or integrally formed. The anti-pinch structure can be installed on the front cover or front compartment, for example, through direct connection, indirect connection (introducing intermediate components), or integral forming (such as machining an anti-pinch structure on the front cover or front compartment).
[0014] Taking "the anti-pinch structure is disposed in at least a portion of the first gap area" as an example, it may include, but is not limited to:
[0015] (1) The first anti-pinch mechanism includes multiple anti-pinch structures, at least two of which are arranged at intervals in the first gap area, and thus the combination of multiple anti-pinch structures is only configured in a part of the first gap area;
[0016] (2) The first gap area is divided into multiple sub-parts, and one or more of these sub-parts are not equipped with anti-pinch structures, thus making the anti-pinch structures only configured in local areas of the first gap area. In this functional case, for the local area where the anti-pinch structures are required, adjacent anti-pinch structures can be configured continuously or at intervals within the local area.
[0017] In one possible implementation of the aforementioned vehicle hood assembly, the anti-pinch structure includes an anti-pinch sealing structure, wherein the first anti-pinch mechanism further includes a first movable mechanism that is signal-connected to the anti-pinch sealing structure, the first movable mechanism being capable of opening the hood.
[0018] This configuration illustrates the possible structural forms of the first anti-pinch mechanism. For example, the sealing structure could be one or more sealing strips.
[0019] It is understandable that those skilled in the art can determine the structural form and operational principle of the first movable mechanism based on actual needs. For example, the anti-pinch sealing structure can be an anti-pinch sealing strip, and the detection results, such as voltage signals, can be used to describe whether the first gap area is in a state requiring anti-pinch protection. The first movable mechanism can be an existing structure of the vehicle capable of opening the hood, or it can be an additional structure. If the first gap area is in a state requiring anti-pinch protection, the hood can be opened by activating the first movable mechanism, thus achieving the anti-pinch function by positioning the hood corresponding to the first gap area.
[0020] It should be noted that the vehicle controller's action of moving the first movable mechanism based on the detection result of the anti-pinch sealing strip to achieve the anti-pinch function for the first gap area is a conventional control logic. In other words, given the signal connection between the anti-pinch sealing strip and the first movable mechanism, this control logic is a reasonable choice and does not involve any improvement to the method.
[0021] In one possible implementation of the aforementioned vehicle hood assembly, the second anti-pinch mechanism includes a second actuating mechanism comprising a drive component capable of driving the hood to open relative to the front compartment; wherein the second actuating mechanism is located on or near the pivot side of the hood.
[0022] With this configuration, it is possible to achieve an anti-pinch function for the second gap area by reverse driving of the drive component (the opposite of driving the front cover to keep it closed).
[0023] If the drive component of the second movable mechanism is located on or near the pivot side of the front cover, the load on the second movable mechanism will change significantly when the second gap area is in a state requiring anti-pinch protection. At this time, the front cover can be opened by the drive component. The drive component can be a drive motor or a power cylinder (such as an electric cylinder or a pneumatic cylinder). Taking a drive motor as an example, the torque of the drive motor will change significantly when the second gap area is in a state requiring anti-pinch protection.
[0024] It should be noted that the vehicle controller's action of moving the second movable mechanism to achieve an anti-pinch state for the second gap area when the load changes significantly is a conventional control logic. In other words, assuming the second movable mechanism includes a drive component, the control logic of reversing the drive component when the load changes abruptly does not involve improvement but is a reasonable choice.
[0025] Similar to the first movable mechanism described above, those skilled in the art can determine the structural form and operational principle of the second movable mechanism according to actual needs. It can be directly driven by a drive component or indirectly driven by a transmission mechanism. The second movable mechanism can be an existing structure in the vehicle capable of opening the hood, or it can be an additional structure added on top of it.
[0026] In one possible implementation of the aforementioned vehicle hood assembly, the hood assembly includes a third actuating mechanism capable of opening the hood relative to the front compartment; wherein the first actuating mechanism, the second actuating mechanism, and the third actuating mechanism are independently configured or at least integrated to some extent.
[0027] With this configuration, it is possible to achieve the normal opening and closing function of the front cover through a third moving mechanism.
[0028] Similar to the first / second moving mechanism mentioned above, those skilled in the art can determine the structural form of the third moving mechanism and the principle of rotation based on actual needs.
[0029] In cases where the second and third movable mechanisms are independently configured, their installation positions are relatively close. When the second and third movable mechanisms are integrated to at least a certain extent, they can share mounting carriers unrelated to transmission, such as mounting bases, or they can share parts or all of the structure related to transmission, such as drive components.
[0030] In one possible implementation of the aforementioned vehicle hood assembly, the first movable mechanism, the second movable mechanism, and the third movable mechanism are combined into one unit.
[0031] This design simplifies the structure of the front cover assembly.
[0032] In one possible implementation of the hood assembly of the aforementioned vehicle, the third actuating mechanism is an electric support rod assembly.
[0033] This configuration provides a possible structural form for the third activity mechanism (which also serves as the first / second activity mechanism).
[0034] It is understood that those skilled in the art can use electric support rod assemblies of any structural form according to actual needs, such as including a drive motor, a transmission mechanism including gears, and a telescopic support rod.
[0035] In one possible implementation of the aforementioned vehicle hood assembly, the hood assembly includes a locking component configured on or near the free side of the vehicle corresponding to the hood.
[0036] This configuration ensures the reliability of the hood when it is closed. For example, the locking assembly typically includes a pair of mating features, one of which is located on the hood and the other on the front compartment.
[0037] It is understandable that those skilled in the art can select any structural form and locking principle of locking components to realize the opening and closing of the front cover according to actual needs, such as through mechanical connection such as buckles, magnetic adsorption, etc.
[0038] In one possible implementation of the aforementioned vehicle's hood assembly, the locking assembly is capable of connecting the hood to the front compartment via electro-adhesion.
[0039] With this configuration, when the aforementioned first / second gap area is in a state requiring anti-pinch protection, the anti-pinch function of the front cover assembly can be reliably achieved by interrupting the electrical signal. It is understood that those skilled in the art can determine any principle and structural form of the locking component (electric suction lock) as the locking component of this utility model according to actual needs.
[0040] It should be noted that, given the electric suction lock has a signal connection with the aforementioned first / second / third moving mechanisms, interrupting the power supply to the electric suction lock when it is necessary to lift the front cover during the closing process is a conventional control logic. In other words, the control logic of interrupting the power supply to the electric suction lock to ensure that the front cover can be opened smoothly is a reasonable choice and does not involve any improvement to the method.
[0041] In a second aspect, the present invention provides a vehicle that includes the front cover assembly described in any of the preceding claims.
[0042] It is understood that the vehicle has all the technical effects of the hood assembly of any of the aforementioned vehicles, and will not be repeated here. Attached Figure Description

[0058] The preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. For example, although this embodiment is described in conjunction with the first / second / third movable mechanisms integrated into a single electric support rod assembly, this is not intended to limit the scope of protection of the present invention. Without departing from the principles of the present invention, those skilled in the art can flexibly adjust the structural form and specific arrangement of the first / second / third movable mechanisms. For example, two or three of them can be configured as at least partially integrated structures.
[0059] It should be noted that in the description of this utility model, terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," indicating directional or positional relationships, are based on the directional or positional relationships shown in the accompanying drawings.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The singular forms of the terms "a" and "this" may also include plural forms.
[0060] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0061] Furthermore, to better illustrate this utility model, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this utility model can still be implemented without certain specific details. In some examples, electric support rods, anti-pinch sealing strips, and control logic that can be reasonably implemented based on signal connections, which are well known to those skilled in the art, are not described in detail, in order to highlight the main points of this utility model.
[0062] Main reference Figure 1 and Figure 2 In one possible implementation, the vehicle includes a front compartment and a hood assembly 100. The front compartment has a front trunk, and the hood assembly 100 includes a hood 1 and an anti-pinch part 3. The hood 1 is openable in the front compartment, thus allowing the front trunk to be in an open or closed state. A gap area 2 exists between the hood 1 and the front compartment. The anti-pinch part 3 includes multiple anti-pinch mechanisms disposed in different portions of the gap area 2, providing anti-pinch functionality for corresponding portions of the gap area 2. In this way, by combining multiple anti-pinch mechanisms, anti-pinch functionality can be achieved for different portions of the gap area 2, potentially achieving full-area anti-pinch functionality along the gap area 2 for the hood assembly 100. This improves the user's safety experience when closing the hood 1.
[0063] In one possible implementation, the front cover 1 is rotatably disposed on the front compartment, thus giving the front cover assembly 100 a pivot side 11 and a free side 12 disposed opposite to each other. Exemplarily, the front cover 1 is pivotally (rotatably) disposed on the front compartment via a hinge 5. The gap area 2 includes a first gap area 21 near the pivot side 11 and a second gap area 22 near the free side 12. Accordingly, the anti-pinch mechanism includes a first anti-pinch mechanism and a second anti-pinch mechanism, wherein the first anti-pinch mechanism is used to implement an anti-pinch function for the first gap area 21, and the second anti-pinch mechanism is used to implement an anti-pinch function for the second gap area 22.
[0064] In one possible implementation, the first anti-pinch mechanism mainly includes an anti-pinch structure 311 and a first movable mechanism 312, wherein the anti-pinch structure 311 is disposed in at least a portion of the first gap area 21. In this example, the anti-pinch structure 311 is an anti-pinch sealing structure (such as an anti-pinch sealing strip). If, during the closing process of the front cover 1, an obstruction (such as a user's hand) occurs in the area where the anti-pinch sealing strip is located, the two conductive sides of the anti-pinch sealing strip will come into contact due to compression, thereby changing the internal circuitry of the anti-pinch sealing strip. Based on this change in circuitry, a change in signal, such as voltage, can be generated. At this time, the position corresponding to the first gap area 21 can be considered to be in a state requiring anti-pinch protection. Based on the signal connection between the anti-pinch sealing strip and the first movable mechanism 312, a controller (such as a vehicle controller or a controller specifically for the anti-pinch function) can cause the first movable mechanism 312 to move the front cover 1 in the direction that opens it, according to the signal change. In this example, the first / second / third movable mechanisms are all electric support rod assemblies. If the controller extends the support rod of the electric support rod assembly, the front cover 1 can be opened. For example, during the closing process of the front cover 1, the drive motor of the electric support rod assembly rotates forward. When the front cover assembly 100 is in a state that requires anti-pinch protection at the position corresponding to the first gap area 21, the anti-pinch function for the first gap area 21 can be achieved by reversing the drive motor.
[0065] In one possible implementation, the second anti-pinch mechanism mainly includes a second movable mechanism 321. As mentioned above, in this example, the first, second, and third movable mechanisms are all electric support rod assemblies. If there is an obstruction at the position corresponding to the first gap area 21, the load on the electric support rod assembly will change, thus causing a change in the signal inside the electric support rod assembly, such as an increase in the torque of the drive motor of the electric support rod assembly. At this time, by reversing the drive motor, the support rod of the electric support rod assembly can be raised, thereby realizing the anti-pinch function for the first gap area 21. The second movable mechanism 321 is located on or near the pivot side 11 of the front cover 1. If a human-bearable anti-pinch force can be preset (such as a force between 80-120N, which can be flexibly defined by those skilled in the art according to actual needs or relevant standards), when the signal inside the movable support rod assembly changes beyond the bearable range, it can be considered that the front cover assembly 100 is in a state requiring anti-pinch at the position corresponding to the second gap area 22.
[0066] In one possible implementation, the front cover assembly 100 includes a third actuating mechanism 4, which is mainly used to open the front cover 1 relative to the front compartment, thereby ensuring the normal use of the front trunk. Referring to the preceding text, in this example, the first / second / third actuating mechanisms are all electrically operated support rod assemblies. Therefore, in this example, the electrically operated support rod assembly enables the normal opening of the front cover 1, provides an anti-pinch function for the first gap area 21 (through cooperation with the anti-pinch sealing strip), and provides an anti-pinch function for the second gap area 22.
[0067] In one possible implementation, the hood assembly 100 includes a locking assembly 6 disposed on the free side 12 of the vehicle corresponding to the hood 1. As in this example, the locking assembly 6 can connect the hood 1 to the front compartment by electro-adhesion, and may be referred to as an electro-adhesive lock.
[0068] In accordance with the aforementioned anti-pinch function for the first gap area 21 (through cooperation with the anti-pinch sealing strip) and the anti-pinch function for the second gap area 22, when the anti-pinch function needs to be implemented, the controller simultaneously interrupts the power supply to the electric suction lock to ensure that the support rod can smoothly push the front cover 1 open at least part of the way in the direction that makes the front cover 1 open, thereby ensuring that the anti-pinch state is smoothly eliminated.
[0069] As can be seen, in the preferred embodiment of this utility model, by dividing the gap area between the front cover 1 and the front compartment into different regions along the vehicle length direction, and configuring anti-pinch mechanisms for different regions, full-area anti-pinch protection of the front cover assembly 100 is achieved, that is, the anti-pinch function of the front cover 1 is realized during opening and closing. Specifically, in the first gap area 21 near the pivot side 11, due to the existence of the lever principle, the attraction force of the electric suction lock in the first gap area 21 is far beyond the range that a person can withstand. Therefore, the anti-pinch function for the first gap area 21 is achieved through the cooperation of the anti-pinch sealing strip and the electric support rod assembly. In the second gap area 22 near the free side 12, the anti-pinch function is achieved through the electric support rod assembly, that is, the anti-pinch function for the area of the front cover assembly 100 near the free side (the range of action can be obtained by force balance conversion) is achieved through the electric support rod assembly. In this way, especially for the front compartment with a front trunk, since the front cover 1 is used more and more frequently, the safety experience of users such as drivers and passengers can be significantly improved.
[0070] The technical solution of this utility model has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
