Description

Technical Field

[0001] The present invention relates to a glove box structure, and more particularly to a graphene glove box. Background Art

[0002] Generally, a dashboard extending in front of both the driver's seat and the passenger seat is provided on the front side of a vehicle. The dashboard is usually an operation part for instrument devices, air conditioners, audio and other electronic devices, an air-conditioning air outlet, and an assembly of a glove box.

[0003] The glove box is provided directly in front of the passenger side of the vehicle and is an openable and closable sundry storage box. The automotive glove box is an interior functional part that is frequently used by users in daily use, and its use experience directly affects the user's intuitive experience of the vehicle quality.

[0004] To improve the user experience, various glove boxes with structural improvements have emerged in the prior art. The Chinese utility model patent with the publication number CN112572300B and the patent name "Glove Box and Vehicle Comprising the Glove Box" discloses a glove box for a vehicle, including an inner glove box panel and an outer glove box panel. When the glove box is in a closed state, the outer glove box panel is joined to the instrument panel of the vehicle dashboard at the interface. The outer glove box panel defines a hollow cavity and has an outer panel opening leading to the hollow cavity at the interface. An outer sealing airbag is at least partially received in the hollow cavity. The internal space of the glove box is defined by an elastic material airbag, which is at least partially attached to at least one of the inner surface of the inner glove box panel, the inner surface of the outer glove box panel, and the inner surface of the instrument panel, and has an opening at the interface. The elastic material airbag is configured to automatically seal the opening airtight when the glove box is closed, so that the elastic material airbag forms an inner sealing airbag. Among them, at least one of the outer surface of the outer glove box panel facing away from the internal space and the outer panel of the vehicle dashboard is attached with an elastically deformable device. The present application also provides a vehicle including the glove box.

[0005] In the prior art, a heating structure is provided in the seat and the armrest to improve the customer experience, because a relatively large space can be provided in both the seat and the armrest for the installation of the heating mechanism. However, due to the limitation of the thickness of the glove box cover, it is impossible to set a heating structure at the glove box position to heat the legs of the driver and passengers, which not only reduces the customer experience but also hinders the development of the glove box field. Summary of the Invention

[0006] In view of the deficiencies in the prior art, the present invention provides a graphene glove box, which can heat the legs of the driver and passengers, does not occupy the space of the glove box, and has a long service life.

[0007] To solve the above technical problems, the present invention is solved by the following technical solutions: A graphene glove box, comprising a glove box housing and a cover plate assembly for driving the storage box inside the glove box to flip. The cover plate assembly includes a cover plate body formed by combining a coated skeleton and a surface layer, with a working cavity inside. A heating component layer is arranged in the working cavity, including a heat insulation layer, a packaging layer, and a graphene heating layer. The electrical connection end of the heating component layer extends from the lower working end of the working cavity and extends towards the lower working part of the glove box housing, and is matched with an extension mechanism fixed to the lower working part of the glove box housing.

[0008] In the above technical solution, the packaging layer includes a first packaging layer and a second packaging layer symmetrically attached to two working surfaces of the graphene heating layer, and an elastic layer is compositely arranged on the first packaging layer close to the surface layer side.

[0009] In the above technical solution, the extension mechanism includes an extension seat, and the electrical connection end of the heating component layer is connected in cooperation through the extension seat.

[0010] In the above technical solution, the extension seat includes a seat body, a reserved cavity, a fixing mechanism installation position, and a first wire harness guiding groove are arranged along the upper working surface of the seat body, and a second wire harness guiding groove is arranged on the lower working surface of the seat body.

[0011] In the above technical solution, a first limiting member and a second limiting member are respectively arranged on the first wire harness guiding groove and the second wire harness guiding groove, for fixing the wire harness and guiding it to be arranged along the directions of the first wire harness guiding groove 43 and the second wire harness guiding groove 44.

[0012] In the above technical solution, a connecting arm for connecting with the glove box housing is arranged along the width direction of the seat body.

[0013] In the above technical solution, the positive wiring terminal, the negative wiring terminal, and the temperature sensor arranged on the lower working surface of the electrical connection end of the heating component layer are all located in the reserved cavity. The wire harness connected to the power supply connector is respectively electrically connected to the positive wiring terminal, the negative wiring terminal, and the temperature sensor after being guided by the first wire harness guiding groove and the second wire harness guiding groove, and the sensor can be used to adjust the temperature in real time.

[0014] In the above technical solution, an extension seat installation part and a wire harness reserved position for allowing the wire harness to pass through and be limited are arranged on the lower working part of the glove box housing.

[0015] In the above technical solution, at least two fixing mechanisms for the wire harness are arranged between the second wire harness guiding groove and the wire harness reserved position. Through the fixing mechanisms at the two installation points, the wire harness moves along a predetermined movement trajectory when opening and closing, the structure is more durable, and the service life of the mechanism is extended.

[0016] In the above technical solution, a number of wire harness guiding and fixing positions are provided on the glove box housing at the rear side of the wire harness reserved position.

[0017] Compared with the prior art, the present invention has the following beneficial effects: Compared with the prior art, the present invention has the following beneficial effects: The heating component is arranged in the cover plate component, and the electrical connection end of the heating component is extended and arranged to be connected to the glove box housing, which not only ensures the temperature control requirements of the cover plate surface, but also can reduce the thickness of the cover plate, release the space of the glove box and the heating space for the legs in the vehicle. The reduction of the cover plate thickness can directly reduce the material consumption, and at the same time, it allows the use of lighter composite materials, meeting the lightweight design trend (such as the requirements of new energy vehicles); the cover plate does not need to add a complex structure to accommodate the sensor, and can more freely achieve a streamlined or compact appearance, improving the aesthetic degree of the product; the extension piece design can reduce this stress accumulation and extend the service life of the sensor; the elastic layer is used to absorb the uneven appearance caused by the gap, making the covered surface smoother while improving the touch, taking into account both aesthetics and practicality.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings.

[0028] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and other obvious deformations can be thought of by those skilled in the art. The basic principles defined in the following description can be used in other implementation schemes, deformation schemes, improvement schemes, equivalent schemes, and other technical schemes without departing from the spirit and scope of the present invention.

[0029] Those skilled in the art should understand that in the disclosure of the present invention, the orientations or positions indicated by the terms "longitudinal", "transverse", "upper", "lower", "left", "right", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientations or position relationships shown in the drawings. It is only for the convenience of simplifying the description of the present invention, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on the present invention.

[0030] It can be understood that the term "one" should be understood as "at least one" or "one or more". That is, in one embodiment, the number of one component can be one, while in other embodiments, the number of this component can be multiple. The term "one" should not be construed as a limitation on the quantity.

[0031] See Figures 1 to 6 , a graphene glove box, including a glove box housing 1 and a cover plate assembly 3 that drives the storage box 2 in the glove box housing 1 to flip. The cover plate assembly 3 includes a cover plate body, which is formed by combining a covering skeleton 31 and a surface layer 32. A working cavity that is closed at the top and open at the lower end is formed between the covering skeleton 31 and the surface layer 32. A heating component layer is arranged in the working cavity. From the middle graphene heating layer 35 towards the covering skeleton 31, a second encapsulation layer 342 and a heat insulation layer 33 are arranged in sequence. Towards the surface layer 32, a first encapsulation layer 341 is arranged in sequence. An elastic layer is compounded on the first encapsulation layer 341 close to the surface layer 32 side. The elastic layer can be a foam layer or a mesh layer, such as mesh or foam, with a thickness ≥ 1.5 mm, used to absorb the uneven appearance caused by voids, make the covering surface smoother, and at the same time improve the touch, taking into account both aesthetics and practicality.

[0032] In order to reduce the thickness of the glove box cover plate, the heating part of the heating component layer is compounded and arranged in the working cavity, while the electrical connection end of the heating component layer extends from the lower working end of the working cavity and then extends towards the lower working part of the glove box housing 1, and is matched with the extension mechanism fixed to the lower working part of the glove box housing 1. In this way, the components that occupy a large space are separated from the cover plate assembly 3, that is, the thickness of the glove box cover plate can be reduced, while enhancing the texture of the cover plate, and the function of providing heating for the legs of the driver and passengers can also be achieved.

[0033] The extension mechanism includes an extension seat 4. The extension seat 4 includes a seat body. Along the width direction of the seat body, a connecting arm 45 for connecting with the glove box housing 1 is arranged, which is used for fixedly connecting with the extension seat installation part of the lower working part of the glove box housing 1. Along the upper working surface of the seat body, a concave reserved cavity 41, a fixing mechanism installation position 42 and a concave first wire harness guiding groove 43 are arranged. On the lower working surface of the seat body, a second wire harness guiding groove 44 protruding towards the working surface of the first wire harness guiding groove 43 is arranged. The fixing mechanism installation position 42 is a through-hole structure and is used for connecting a fixing mechanism 6.

[0034] A first limiting member 431 and a second limiting member 441 are respectively arranged on the first wire harness guiding groove 43 and the second wire harness guiding groove 44. The first limiting member 431 and the second limiting member 441 are preferably snap structures and are used for fixing the wire harness and guiding it to be arranged along the directions of the first wire harness guiding groove 43 and the second wire harness guiding groove 44.

[0035] The positive terminal 351, the negative terminal 352 and the temperature sensor 353 arranged on the lower working surface of the electrical connection end of the heating component layer are all located in the reserved cavity 41. The wire harness 5 connected to the power supply connector is electrically connected to the positive terminal 351, the negative terminal 352 and the temperature sensor 353 respectively after being guided by the first wire harness guiding groove 43 and the second wire harness guiding groove 44.

[0036] The wire harness 5 led out from the second wire harness guiding groove 44 of the extension seat 4 is limited by one of the fixing mechanisms 6 installed on the fixing mechanism installation position 42, and then is limited by the fixing mechanism 6 arranged on the second fixing mechanism installation position 13 on the lower working part of the glove box housing 1. At least two fixing mechanisms 6 for the wire harness are arranged between the second wire harness guiding groove 44 and the wire harness reserved position 11. Preferably, two are arranged here. Of course, the number of the fixing mechanisms 6 can be adjusted according to different models of wire harnesses or structural arrangements.

[0037] The wire harness 5 then extends to the rear working surface of the glove box housing 1 through the wire harness reserved position 11 arranged on the lower working part of the glove box housing 1, and is fixedly guided by a plurality of wire harness guiding and fixing positions 12 arranged on the glove box housing 1 at the rear side of the wire harness reserved position 11 and then connected to the power supply.

[0038] Through the above solution, by arranging a second encapsulation layer 342 and a heat insulation layer 33 outside the graphene heating layer 35, a first encapsulation layer 341 and an elastic layer, while not affecting the thickness of the cover plate, the flatness of the cover plate surface is ensured, the texture of the cover plate is enhanced, and at the same time, the function of heating the legs of the driver and passengers can be provided, which has a forward-looking guiding significance for the development of the glove box function.

[0039] In the present invention, the sensor is placed on the extension piece and moved out of the cover plate, which not only ensures the temperature control requirements on the cover plate surface but also reduces the thickness of the cover plate, releasing the space of the glove box and the heating space for the legs in the vehicle. The reduction of the cover plate thickness can directly reduce the material consumption and at the same time allow the use of lighter composite materials, meeting the lightweight design trend (such as the requirements of new energy vehicles). The cover plate does not need to add a complex structure to accommodate the sensor and can more freely achieve a streamlined or compact appearance, improving the aesthetics of the product.

[0040] In the traditional wrapping design, stress may be generated between the sensor and the cover plate material due to thermal expansion, which may affect the structural stability after long-term use. The extension piece design can reduce this stress accumulation and extend the service life of the sensor.

[0041] The existing graphene sheets mainly consist of a heat insulation layer, an encapsulation layer, and a graphene layer. The graphene layer is composed of a heating layer and a conductive layer, and there are gaps between the heating layer and the conductive layer. After wrapping, the appearance is uneven. On this basis, the present invention adds an elastic layer, which is a foam layer or a mesh layer with a thickness greater than or equal to 1.5 mm, to absorb the unevenness of the appearance caused by the gaps, making the wrapped surface smoother, improving the touch feeling, and taking into account both aesthetics and practicality.

[0042] The graphene extension piece is difficult to fix itself and is prone to wear and failure during the opening and closing process of the glove box. By adding an extension base, a wire harness is led out from the extension piece and fixed at multiple points, at least two points, to ensure the connection reliability and durability. If there is a strong electromagnetic environment (such as motors, frequency converters) in the glove box, the extension base can be designed as a metal shielding structure to reduce signal interference and improve reliability. The extension base can be integrated with a protective cover or a shock-absorbing structure to prevent the sensor from being damaged due to vibration or collision. Through multi-layer fixation, such as the combination of a limiting part and a fixing mechanism, wear is prevented and potential safety hazards are avoided.

[0043] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the drawings are only examples and do not limit the present invention. The object of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and described in the embodiments. Without departing from the above principles, the embodiments of the present invention can have any deformation or modification.
