Description

Technical Field

[0001] This invention belongs to the field of electric vehicle technology, specifically relating to a front trunk, front engine compartment, and automobile. Background Technology

[0002] The electric vehicle market is expanding rapidly, with sales volume and market penetration steadily increasing. In China, new energy vehicles have secured a place in the automotive market, demonstrating rapid growth in sales figures and market share. Electric vehicle technology continues to advance, particularly in areas such as driving range, charging speed, and autonomous driving, achieving significant progress. Furthermore, various countries are increasing policy support for the electric vehicle industry, implementing a series of policy measures to accelerate its development. The development of the front trunk in electric vehicles has evolved from non-existent to complex. Initially, electric vehicles did not have a front trunk design. The engine was eliminated, and the drive motor was placed at the rear. Through optimized layout, the main components of the three-electric system, such as the motor controller and the three-in-one controller, were all located at the rear of the vehicle. Based on consumer demand, the space previously occupied by the engine was used to add a front trunk, increasing storage space. The front trunk has gradually become standard equipment on some models. Currently, electric vehicles equipped with front trunks on the market have relatively complex trunk structures, and the existing layout results in most parts of the front compartment being covered, making the maintenance of these covered parts difficult. Existing removable front trunks typically use traditional methods such as snap-fit ​​connections, which are difficult to disassemble, prone to damaging parts, time-consuming, labor-intensive, and extremely inconvenient. With rising living standards, road trips have become the preferred choice for many travelers. However, during road trips, passengers usually carry additional suitcases to meet the need for mobile storage, which requires additional storage space inside the car or in the front and rear trunks, making it very inconvenient. Summary of the Invention

[0003] The purpose of this invention is to provide a front trunk, front engine compartment, and automobile. An electromagnetic connector is installed on the front trunk floor, with an electromagnet inside. Magnetic material is installed inside the storage compartment floor of the front trunk. When the electromagnet is energized, it magnetically connects to the storage compartment floor, thus fixing the storage compartment to the front trunk floor and realizing its storage function. When other parts in the front engine compartment need repair, the electromagnet is de-energized to eliminate its magnetism, allowing the storage compartment to be easily removed from the front trunk, exposing the parts hidden by the storage compartment for easy repair. Furthermore, by modifying the structure of the storage compartment to make it retractable, and by embedding foldable wheels at the bottom of the storage compartment, and adding a retractable handle to the outer wall of the storage compartment, the storage compartment can be used independently after being removed, providing mobile storage space for passengers traveling.

[0004] The specific details of the plan are as follows:

[0005] A car front trunk includes a retractable storage box, an electromagnetic connector, and a front trunk floor. The storage box includes a side panel, a bottom plate, and a telescopic self-locking assembly. The side panel has a telescopic structure that can move up and down or left and right. The lower end of the side panel is set on the bottom plate to form a rectangular box structure with an opening at the top. The telescopic self-locking assembly is matched and set on the telescopic structure of the side panel. The bottom plate is magnetic. The upper end of the electromagnetic connector is magnetically connected to the lower end face of the bottom plate, and the lower end of the electromagnetic connector is fixedly connected to the front trunk floor.

[0006] The storage compartment in the front trunk of this invention is an adjustable-size compartment. The side panels and bottom plate of the storage compartment are matched and connected to form a rectangular box structure. Each of the four lower corners of the bottom plate has an upward-facing rectangular recess, while the central area of ​​the bottom plate forms an outward protrusion. Magnetic material is uniformly housed and fixed within the outward protrusion, and an electromagnet is installed within an electromagnetic connector. The electromagnet is electrically connected to the vehicle's wiring harness. The number of electromagnets is set according to actual needs. When energized, the electromagnets generate magnetism, magnetically connecting with the electromagnetic material fixed within the outward protrusion of the bottom plate to secure the storage compartment and the front trunk floor. When the storage compartment needs to be removed, simply de-energize the electromagnets to demagnetize them, and it can be removed, saving time and effort without damaging other parts, greatly facilitating the maintenance of parts in the front engine compartment of the vehicle. Traditional fixed front trunks obstruct many parts in the engine compartment, making maintenance difficult. Removing the storage compartment when necessary is time-consuming, laborious, and prone to damaging parts. Magnetic storage compartments completely avoid this problem, offering simple and quick operation. The electromagnetic material can be a permanent magnet or other magnetic material. Four wheels are installed for easy movement when the storage compartment is removed for individual use; all four wheels are omnidirectional, providing greater flexibility and ease of steering. The four wheels are hinged to the end faces of rectangular recesses at the four corners of the base plate. When not in use, the wheels can be folded and stored within the rectangular recesses without affecting the electromagnetic connection between the upper and lower ends of the electromagnetic connector. When the wheels are needed, they are rotated 90 degrees and pulled out of the rectangular recesses, positioned below the lower end of the outer protrusion, ensuring smooth rolling and preventing the outer protrusion from contacting the ground.

[0007] A U-shaped groove is provided on the outer surface of the wall of any short side panel. The handle is hinged and embedded in the U-shaped groove, with the hinge axis located at the upper opening of the U-shaped groove. When the storage box is installed in the front trunk of the vehicle, the handle is hidden in the side panel; when the storage box is removed and used as a mobile storage space, the hidden handle can be flipped over and pulled out from the U-shaped groove of the side panel for convenience and speed.

[0008] The present invention modifies the structure of the storage box, allowing its size to be adjusted. The reasons and purposes for this adjustment are mainly twofold: firstly, the original storage box is too small to meet the storage needs of passengers, necessitating a larger storage box; secondly, the original storage box is too large, especially its long side, making it very inconvenient to use, requiring a smaller storage box. One structure of the present invention achieves the increase or decrease of storage space through a double-layered side panel structure that can slide up or down and self-locking. Another structure of the present invention achieves the purpose of increasing or decreasing storage space by dividing the box structure composed of the side panels and the bottom plate into a left box and a right box that can slide horizontally and self-lock against each other.

[0009] Furthermore, the side panel includes an outer panel and an inner panel. Both the outer panel and the inner panel are rectangular shells with open upper and lower ends. The lower end of the inner panel is fixedly connected to the bottom plate. Matching concave-convex sliding connection structures are vertically provided at corresponding positions on the inner surface of the outer panel and the outer surface of the inner panel. The outer panel and the inner panel match to form an integral rectangular shell. The telescopic self-locking component is matched and set at the corresponding position of the concave-convex sliding connection structure. The outer panel can slide vertically along the outer surface of the inner panel and can self-lock and limit its position.

[0010] Both the outer and inner side panels are rectangular shells open at both the top and bottom. While the outer and inner panels feature grooves and rails, they do not utilize a traditional groove and rail system. This allows the outer and inner panels to slide together using their own interlocking concave-convex structures, forming a unified rectangular shell. This makes the side panels more robust and less prone to damage. The outer panel can slide up and down along the outer surface of the inner panel and can be self-locked at desired positions by a telescopic self-locking component located between them.

[0011] Furthermore, each of the four inner surfaces of the outer perimeter plate has a first sliding connection portion vertically positioned at the center. The first sliding connection portion is a long rectangular protrusion. The outer surfaces of the four inner perimeter plates are matched with second sliding connection portions at the corresponding positions of the first sliding connection portions. The second sliding connection portions are two long rectangular protrusions vertically spaced on the corresponding outer surfaces of the inner perimeter plates. The first sliding connection portion can be slidably inserted into the second sliding connection portion to form a concave-convex sliding connection structure. The first and second sliding connection portions are matched with telescopic self-locking components. The first sliding connection portion can slide vertically within the second sliding connection portion and is self-locking and limited.

[0012] The specific structure of the outer and inner panels slidingly fitting together is as follows: A rectangular protrusion, i.e., the first sliding connection part, is vertically set in the middle of the inner surface of the four walls of the outer panel. Two rectangular protrusions, i.e., the second sliding connection parts, are vertically spaced at positions corresponding to the first sliding connection parts on the outer surface of the four walls of the inner panel. The second sliding connection parts form a groove structure and match the first sliding connection parts. The first sliding connection parts slide into the second sliding connection parts, forming a concave-convex sliding connection structure. The first and second sliding connection parts are equipped with a telescopic self-locking assembly, which allows them to self-lock and limit their position. The outer panel can be vertically slid to the desired position to self-lock, allowing for easy and quick adjustment of the storage space of the storage box.

[0013] Furthermore, the telescopic self-locking assembly includes a compression spring and a pin. The pin is a round-headed pin. One end of the compression spring is fixedly connected to the tail end of the pin. Blind holes are symmetrically opened on the lower left and right side walls of the first sliding connection. Multiple positioning holes are symmetrically spaced on the left and right inner side walls of the corresponding side of the second sliding connection. The other end of the compression spring is fixedly connected to the inner wall of the blind hole. The compression spring and the pin can be elastically squeezed and accommodated in the blind hole. The pin head can be elastically limited and locked in the positioning hole.

[0014] The telescopic self-locking assembly includes a compression spring and a pin, the pin being a round-headed pin. One end of the compression spring is fixedly connected to the tail end of the pin. A blind hole is formed on the lower side wall of the first sliding connection, which can be formed on one side or both sides. Preferably, blind holes are formed on both sides. The number of telescopic self-locking assemblies matches the number of blind holes. Preferably, there are two sets. The other end of the compression spring of each set of telescopic self-locking assemblies is fixedly connected to the corresponding blind hole. Multiple corresponding positioning holes are spaced apart on the side wall adjacent to the first sliding connection. When the outer plate slides up and down along the inner plate, the compression spring and pin are compressed forcefully, causing them to elastically accommodate in the blind hole during the sliding process. When the desired height is reached, the sliding stops, allowing the pin head to elastically extend into the corresponding positioning hole and elastically limit itself in the positioning hole, thus self-locking and limiting the outer plate to this position.

[0015] Furthermore, the rectangular box is a two-part snap-fit ​​structure, including a left box and a right box. The left and right boxes are two interfaces formed by corresponding side panels and bottom plates, which are viewed from the side as "U"-shaped shells. The outer surface of the right end of the left box has a concave step surface in the circumference. The left box also includes two positioning plates, each of which is a long strip-shaped protrusion. The two positioning plates are horizontally fixed to the middle of the outer surface of the front and rear panels of the left box side panel. The right box also includes two positioning grooves, which are horizontally fixed to the middle of the outer surface of the front and rear panels of the right box side panel. Each positioning groove includes two rectangular protrusions, which are parallel and spaced apart and fixed to the middle of the outer surface of the front / rear panels of the right box side panel to form a positioning groove. Each positioning plate is matched and slidably inserted into the corresponding positioning groove. The right box side panel can be slidably inserted into the concave step surface and is limited and self-locked by telescopic self-locking components respectively set on the corresponding positioning plates and positioning grooves to form a rectangular box.

[0016] Another method for adjusting the size of the storage box: The storage box is divided into two parts, a left box and a right box, with the interface between the two parts able to be fitted with sliding buckles and self-locking limits. The outer surface of the right end interface of the left box has a concave stepped surface, which actually constitutes the adjustable part. The middle of the front and rear panels of the left box is also provided with positioning plates, which are long strip-shaped protrusions. The middle of the front and rear panels of the right box is provided with matching positioning grooves, which are composed of two spaced rectangular protrusions. The panel wall at the interface of the right box can slide into the concave stepped surface, and is limited and locked by telescopic self-locking components respectively set on the corresponding positioning plates and positioning grooves to form a rectangular box. The telescopic self-locking components used in this invention are the same.

[0017] Furthermore, each positioning plate is slidably inserted into the corresponding positioning groove. On the inner end faces of the two rectangular protrusions of each positioning groove, there are multiple positioning holes symmetrically spaced apart. On the upper and lower end faces of the end adjacent to the interface between the positioning plate and the right box, there are blind holes symmetrically arranged. The telescopic self-locking components are respectively set in the corresponding blind holes. One end of each compression spring is fixedly connected to the inner wall of the blind hole, and the other end is fixedly connected to the tail end of the corresponding pin. The compression spring and the pin can be elastically squeezed and accommodated in the blind hole, and the pin head can be elastically limited and locked in the positioning hole.

[0018] Multiple positioning holes are spaced apart on the upper and lower end faces adjacent to the positioning groove and positioning plate. These positioning holes can be located on either the upper or lower end face; preferably, they are located on both. Blind holes are provided on the upper and lower end faces adjacent to the interface between the positioning plate and the right side of the storage compartment. Two sets of telescopic self-locking components are respectively installed within the corresponding blind holes. One end of a compression spring is fixed within the blind hole, and the other end is connected to a round-headed pin. When adjusting the storage compartment size by stretching the left and right sides of the storage compartment, the compression spring and pin are forcefully compressed, causing them to be accommodated within the blind hole. Once the desired position is reached, the sliding stops, and the pin extends out of the blind hole and elastically locks into the corresponding positioning hole. The storage compartment size varies in different car models. Storage compartments that are too large or too small are not very convenient to use during travel. Therefore, making the storage compartment adjustable in size will better meet the needs of passengers.

[0019] Furthermore, the storage box also includes four wheels. Each of the four corners of the lower end face of the base plate has an upward-facing rectangular recess. Each wheel is a swivel wheel. The four wheels are respectively hinged to the end face of the rectangular recess and can be folded and accommodated in the rectangular recess. The middle part of the base plate forms an outward protrusion. The four wheels can be flipped and extended outward from below the outward protrusion. The base plate also includes magnetic material, which is uniformly accommodated and fixed in the outward protrusion. The electromagnetic connection seat includes an electromagnet, which is electrically connected to the wiring harness inside the vehicle and magnetically connected to the magnetic material in the outward protrusion.

[0020] The lower end of the base plate has four rectangular recesses at its corners, each concave upwards. The wheels are hinged within these recesses and can be folded and stored within them. The wheels are all-wheel drive, facilitating easy removal and individual use. In contrast to the rectangular recesses, the center of the base plate forms a convex section, within which magnetic material is evenly housed and fixed. The electromagnet wires of the electromagnetic connector are connected to the vehicle's wiring harness; when the electromagnet is energized, the magnetic material is electrically connected. The electromagnetic connector is fixedly mounted on the front trunk floor, and its upper surface can magnetically connect with the electromagnetic material in the convex section of the base plate. This magnetic connection method makes the removal and installation of the storage compartment simple and convenient, facilitating both maintenance of parts in the engine compartment and allowing passengers to easily remove and use the storage compartment independently.

[0021] Furthermore, the storage box also includes a handle. A U-shaped groove is provided on the outer surface of the panel wall corresponding to any short side of the side panel. The handle is hinged 180 degrees into the U-shaped groove and the hinge shaft is located at the upper opening of the U-shaped groove.

[0022] A U-shaped groove is provided on the outer surface of the side panel corresponding to the short side of the storage box. The handle is hinged 180 degrees to the opening at the upper end of the U-shaped groove. Normally, it is hidden on the surface of the side panel. When needed, it can be flipped and pulled out to facilitate the need for moving and storing items.

[0023] A front engine compartment, including the aforementioned front trunk of a vehicle.

[0024] An automobile, including the aforementioned front engine compartment.

[0025] Compared with the prior art, the present invention has the following advantages:

[0026] 1. The storage box bottom plate of the present invention is equipped with magnetic material, and the electromagnetic connector is fixedly connected to the front trunk floor. After the electromagnet in the electromagnetic connector is energized, it is magnetically connected to the magnetic material in the storage box bottom plate, so that the storage box in the front trunk can be easily and quickly connected or disassembled. This provides convenience for the maintenance of front engine compartment parts, avoids the problems of damage to the connecting parts and difficulty in disassembly caused by traditional snap-fit ​​methods, improves work efficiency and saves maintenance costs.

[0027] 2. The storage box of the present invention can be used as a separate mobile storage space after being removed;

[0028] 3. The storage box of the present invention has a size adjustment structure, which can adjust the size of the storage box according to the needs of the passengers, so as to meet the storage needs of the passengers while taking into account the comfort of the passengers.
