Description

Technical Field

[0001] The invention belongs to the technical field of electric vehicles, and in particular relates to a front trunk, a front engine compartment and a vehicle. Background Art

[0002] The electric vehicle market is in a state of continuous expansion, with its sales volume and market penetration rate rising steadily. In China, new energy vehicles have occupied a place in the automobile market, and their sales figures and market share have shown a rapid growth momentum. Electric vehicle technology continues to advance, especially in terms of driving range, charging speed and autonomous driving, and has made significant progress. In addition, countries are also continuously increasing policy support for the electric vehicle industry and promoting its faster development through a series of policy measures. The development of the front trunk of electric vehicles has gone through a process from nothing to something, from simple to complex. Initially, electric vehicles did not have a front trunk design. Electric vehicles cancelled the engine and the drive motor was placed at the rear. Through layout optimization, the main three-electric system parts such as the motor controller and the three-in-one controller were all arranged at the rear of the vehicle. According to consumer demand, the space of the original engine was used to increase the front trunk, which increased the storage space. The front trunk of electric vehicles has gradually become a standard feature of some models. At present, the electric vehicles on the market that have been equipped with a front trunk have a relatively complex front trunk structure, and the existing layout scheme causes most of the parts in the front cabin of the car to be covered, making it difficult to repair the covered parts. Existing detachable front trunks usually adopt traditional methods such as snap-on connection, which is difficult to disassemble, easily causes parts damage, is time-consuming and labor-intensive, and extremely inconvenient. With the improvement of living standards, self-driving tours have become the first choice for many travelers. However, during self-driving tours, passengers usually carry additional luggage to meet the needs of mobile storage during travel. Doing so requires additional storage space in the car or in the front and rear trunks, which is very inconvenient. Summary of the invention

[0003] The purpose of the present invention is to provide a front trunk, a front engine room and a car of an automobile, wherein an electromagnetic connection seat is installed on the floor of the front trunk, an electromagnet is installed in the electromagnetic connection seat, a magnetic material is installed inside the bottom plate of a storage box of the front trunk, and the electromagnet is magnetically connected to the bottom plate of the storage box after being energized, so that the storage box is fixedly connected to the floor of the front trunk to realize the storage function of the front trunk; when other parts in the front engine room need to be repaired, the electromagnet is powered off to eliminate the magnetism, and the storage box is easily removed from the front trunk to expose the parts covered by the storage box, which is convenient for maintenance; the structure of the storage box is also changed to make the storage box retractable, and foldable wheels are embedded in the bottom of the storage box, and a concealable handle is installed on the outer wall of the storage box, so that the storage box can be used alone after being removed, providing a mobile storage space for passengers when traveling.

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

[0005] A car trunk comprises a telescopic storage box, an electromagnetic connection seat and a trunk floor, the storage box comprises a side panel, a bottom plate and a telescopic self-locking component, the side panel is provided with a telescopic structure which can move up and down or left and right, the lower end of the side panel is arranged on the bottom plate to form a rectangular box structure with an upper end opening, the telescopic self-locking component is matched and arranged on the telescopic structure of the side panel, the bottom plate is magnetic, the upper end of the electromagnetic connection seat is magnetically connected to the lower end surface of the bottom plate, and the lower end of the electromagnetic connection seat is fixedly connected to the trunk floor.

[0006] The storage box of the front trunk of the present invention is a storage box with adjustable size, and the side panels and the bottom plate of the storage box are matched and connected to form a rectangular box structure of the storage box. The lower end surfaces of the four corners of the bottom plate of the storage box are provided with upward rectangular concave parts, and the middle area of ​​the bottom plate forms a convex part. Magnetic materials are evenly accommodated and fixed in the convex part, and an electromagnet is arranged in the electromagnetic connection seat, and the electromagnet is electrically connected to the wiring harness in the car. The number of electromagnets is set according to actual needs. The electromagnet generates magnetism after being energized, and is magnetically connected to the electromagnetic material fixed in the convex part of the bottom plate to complete the fixation of the storage box and the front trunk floor. When the storage box needs to be removed, it only needs to turn off the power of the electromagnet to make it lose its magnetism, and then it can be taken out, which saves time and effort and will not damage other parts, greatly facilitating the inspection and maintenance of parts in the front engine compartment of the car. Because the traditional fixed front trunk blocks many parts in the front cabin, it is very troublesome when maintenance is needed. If necessary, removing the storage box of the front trunk is not only time-consuming and laborious, but also easy to cause damage to the parts. The magnetic storage box completely avoids this problem and is simple and quick to operate. The electromagnetic material can be a magnetic material such as a permanent magnet. The purpose of installing four wheels in the storage box is to facilitate the movement of the storage box when it is removed and used alone. The four wheels are universal wheels, which are more flexible and convenient to turn when in use. The four wheels are hinged on the end faces of the rectangular inner concave parts at the four corners of the bottom plate. When the wheels are not in use, they can be hinged and folded and accommodated in the rectangular inner concave parts, which does not affect the electromagnetic connection between the upper end face of the electromagnetic connection seat and the lower end face of the outer convex part. When the wheel needs to be used, it is turned 90 degrees and pulled out of the rectangular inner concave part and located below the lower end face of the outer convex part to ensure that the wheel can roll smoothly after being pulled out and the outer convex part will not contact the ground.

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

[0008] The storage box of the present invention is structurally changed so that the size of the storage box can be adjusted. There are two main reasons and purposes for the adjustment of the storage box. One is that the original storage box is too small and cannot meet the storage needs of the passengers, so the storage box needs to be enlarged; the other is that the original storage box is too large, especially the long side is too long, which is very inconvenient to use, so the storage box needs to be reduced. One structure of the present invention is to increase or reduce the storage space by means of a double-layer side panel structure that can slide up or down and self-lock. Another structure of the present invention is to increase or reduce the storage space by dividing the box structure composed of the side panels and the bottom panel into a left box and a right box that can slide horizontally and self-lock with each other.

[0009] Furthermore, the side panel includes an outer panel and an inner panel, both of which are rectangular shells open at both 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, and the outer panel and the inner panel are matched to form an overall rectangular shell, the telescopic self-locking component is matched and arranged at the corresponding position of the concave-convex sliding connection structure, and the outer panel can slide vertically along the outer surface of the inner panel and can be self-locked and limited.

[0010] The outer and inner panels of the side panels are both rectangular shells with open ends. The structure of the slide grooves and slide rails on the outer and inner panels does not use the slide groove and slide rail device, so that the outer and inner panels can be slidably sleeved together through their own concave and convex structures to form an integral rectangular shell, making the side panels stronger 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 and limited at the desired position through the telescopic self-locking component arranged between the two.

[0011] Furthermore, a first sliding connection part is vertically provided in the middle of the inner surface of the four panel walls of the outer panel, and the first sliding connection part is a long rectangular protrusion. A second sliding connection part is matched with the position corresponding to the first sliding connection part in the middle of the outer surface of the four panel walls of the inner panel. The second sliding connection part is two long rectangular protrusions vertically spaced on the corresponding outer surface of the inner panel. The first sliding connection part can be matched and slidably inserted in the second sliding connection part to form a concave-convex sliding connection structure. The first sliding connection part and the second sliding connection part are matched with a telescopic self-locking component. The first sliding connection part can vertically slide in the second sliding connection part and self-lock to limit the position.

[0012] The specific structure of the outer plate and the inner plate matching each other in sliding sleeve connection is: a rectangular convex block, i.e., the first sliding connection part, is vertically arranged in the middle of the inner surface of the four plate walls of the outer plate, and two rectangular convex blocks, i.e., the second sliding connection parts, are vertically arranged at intervals at the positions corresponding to the first sliding connection parts on the outer surfaces of the four plate walls of the inner plate, the second sliding connection parts constitute a sliding groove structure and match the first sliding connection parts, and the first sliding connection parts are slidably inserted in the second sliding connection parts to form a concave-convex sliding connection structure. The first sliding connection parts and the second sliding connection parts are matched with a telescopic self-locking component, and the two can be self-locked and limited by the telescopic self-locking component, and the outer plate can be self-locked when it slides vertically to the desired position, which can increase or decrease the storage space of the storage box, which is convenient and quick.

[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 provided on the lower left and right walls of the first sliding connection part, and a plurality of positioning holes are symmetrically spaced on the left and right inner walls on the corresponding sides of the second sliding connection part, 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, and 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, and the pin is a round-headed pin. One end of the compression spring is fixedly connected to the tail end of the pin, and a blind hole is provided on the lower side wall of the first sliding connection part, which can be provided on one side or on both sides. The present invention preferably provides blind holes on both sides, and the number of telescopic self-locking assemblies matches the number of blind holes. The present invention preferably provides two groups, and the other end of the compression spring of each group of telescopic self-locking assemblies is fixedly connected in the corresponding blind hole. A plurality of corresponding positioning holes are arranged at intervals on the side wall adjacent to the second sliding connection part and the first sliding connection part. When the outer plate slides up and down along the inner plate, the compression spring and the pin are strongly squeezed so that they are elastically accommodated in the blind hole during the sliding process. When the required height is reached, the sliding stops, so that the pin head elastically extends into the corresponding positioning hole and is elastically limited in the positioning hole, and the outer plate is self-locking and limited at this position.

[0015] Furthermore, the rectangular box body is a structure formed by clamping two half bodies, including a left box body and a right box body. The left box body and the right box body are two shells with a "U" shape when viewed from the side at the two interfaces respectively formed by corresponding side wall panels and bottom panels. An inward concave stepped surface is circumferentially provided on the outer surface of the right end of the left box body. The left box body also includes two positioning plates, each positioning plate being a long strip-shaped convex block, and the two positioning plates are respectively horizontally and fixedly connected to the middle parts of the outer surfaces of the front and rear plate walls of the side wall panel of the left box body. The right box body also includes two positioning grooves, and the two positioning grooves are respectively horizontally and fixedly connected to the middle parts of the outer surfaces of the front and rear plate walls of the side wall panel of the right box body. Each positioning groove includes two rectangular convex blocks, and the two rectangular convex blocks are fixedly connected in parallel at intervals to form a positioning groove at the middle part of the outer surface of the front / rear plate wall of the side wall panel of the right box body. Each positioning plate is slidably inserted into the corresponding positioning groove in a matching manner, and the side wall panel of the right box body can be slidably inserted into the inward concave stepped surface in a corresponding manner and is limited and self-locked by a telescopic self-locking assembly respectively arranged on the corresponding positioning plate and positioning groove to form a rectangular box body.

[0016] Another solution for adjusting the size of the storage box: The storage box is divided into two parts, namely a left box body and a right box body. The interfaces of the two parts can be slidably clamped and self-locked in a matching manner. An inward concave stepped surface is provided on the outer surface of the interface at the right end of the left box body, and the inward concave stepped surface actually constitutes the adjustable part. Positioning plates are also respectively provided in the middle parts of the front and rear plate walls of the left box body. The positioning plates are long strip-shaped convex blocks. Matching positioning grooves are provided in the middle parts of the front and rear plate walls of the right box body. The positioning grooves are formed by two rectangular convex blocks arranged at intervals. The plate wall at the interface of the right box body can be slidably inserted into the inward concave stepped surface and is limited and self-locked by a telescopic self-locking assembly respectively arranged on the corresponding positioning plate and positioning groove to form a rectangular box body. The telescopic self-locking assembly used in the present invention is the same.

[0017] Furthermore, each positioning plate is slidably inserted into the corresponding positioning groove in a matching manner. On the inner end faces of the two rectangular convex blocks of each positioning groove that face each other, a plurality of positioning holes are symmetrically arranged at intervals. On the upper and lower end faces of the end of the positioning plate adjacent to the interface of the right box body, blind holes are symmetrically provided. The telescopic self-locking assemblies are respectively arranged 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] A plurality of positioning holes are arranged at intervals on the upper and lower end surfaces adjacent to the positioning groove and the positioning plate. The positioning holes can be arranged on the upper end surface or on the lower end surface. The present invention preferably arranges the positioning holes on both the upper and lower end surfaces. Blind holes are respectively arranged on the upper and lower end surfaces adjacent to the interface between the positioning plate and the right box body. Two sets of telescopic self-locking components are respectively arranged in the corresponding blind holes. One end of the compression spring is fixed in the blind hole, and the other end is connected to a round-headed pin. When the left and right boxes are stretched to adjust the size of the storage box, the compression spring and the pin are squeezed vigorously to be accommodated in the blind hole. When the desired position is reached, the sliding is stopped, and the pin extends out of the blind hole and is elastically locked in the corresponding positioning hole. The sizes of storage boxes in the front trunks of different models are different. Storage boxes that are too large or too small are not very convenient to use during travel. Therefore, the storage box is made into a structure with adjustable size to better meet the needs of passengers.

[0019] Furthermore, the storage box also includes four wheels, and the four corners of the lower end surface of the bottom plate are provided with an upward rectangular recessed portion, each wheel is a universal wheel, and the four wheels are respectively hinged on the end surfaces of the rectangular recessed portion and can be folded and accommodated in the rectangular recessed portion. The middle part of the bottom plate constitutes an outer protrusion, and the four wheels can be flipped and extended out from under the outer protrusion. The bottom plate also includes magnetic material, and the magnetic material is evenly accommodated and fixed in the outer protrusion. The electromagnetic connecting seat includes an electromagnet, which is electrically connected to the wiring harness in the vehicle, and the electromagnet is magnetically connected to the magnetic material in the outer protrusion.

[0020] The four corners of the lower end surface of the bottom plate are provided with an upwardly concave rectangular recess, and the wheels are hinged in the rectangular recess and can be folded and accommodated therein. The wheels are all universal wheels, which are convenient for disassembly and removal for separate use. Relative to the rectangular recess, the middle part of the bottom plate constitutes a convex part, and the magnetic material is evenly accommodated and fixed in the convex part. The electromagnet wires of the electromagnetic connection seat are connected to the wiring harness inside the vehicle, and the magnetic material is electrically connected after the electromagnet is energized. The electromagnetic connection seat is fixedly installed on the floor of the front trunk, and its upper end surface can be magnetically connected to the electromagnetic material in the convex part of the bottom plate. The magnetic connection method makes the disassembly process of the storage box simple and convenient, which is convenient for the maintenance of parts in the front cabin, and it is also convenient for passengers to disassemble the storage box and use it separately when traveling.

[0021] Furthermore, the storage box also includes a handle, and a U-shaped groove is provided on the outer surface of the board wall corresponding to any short side of the side panel. The handle is hinged 180 degrees and embedded in the U-shaped groove, and the hinge axis is arranged at the upper end opening of the U-shaped groove.

[0022] A U-shaped groove is arranged on the outer surface of the board wall corresponding to the short side of the storage box side panel, and the handle is hinged 180 degrees at the opening at the upper end of the U-shaped groove. It is usually hidden on the surface of the side panel and can be flipped and pulled out when needed, so as to conveniently meet the needs of mobile storage.

[0023] A front cabin comprises the aforementioned automobile front trunk.
