Description

Technical Field

[0001] This invention relates to the field of vehicle-mounted mechanical devices, and more particularly to a multi-door telescopic trunk and vehicle. Background Technology

[0002] With the development of the automotive industry, consumers have placed higher demands on the functionality and convenience of automobiles. Traditional car trunk designs primarily feature a liftgate style, which is the most common design. The trunk door opens by lifting upwards, typically to a maximum angle of 90°. While this trunk design is structurally simple, its space is fixed from the initial design stage and can no longer fully meet the needs of modern users, especially with the following shortcomings:

[0003] Loading inconvenience: Traditional liftgate trunks have limited opening angles and a single opening method, failing to provide convenient access from multiple angles. Furthermore, the internal space layout of the trunk is fixed, making it difficult to accommodate items of different sizes. When loading large items, users need to bend over or climb into the trunk, which is difficult and physically demanding. It is also inconvenient for multiple people to access items from multiple angles simultaneously.

[0004] Inconvenient to use in rainy weather: Traditional trunk designs cannot effectively block rainwater when the trunk door is opened in rainy weather, requiring users to use additional rain gear, which increases the complexity and inconvenience of operation.

[0005] Low space utilization: Because the space of a traditional trunk is fixed and cannot be adjusted according to actual needs, the trunk occupies too much rear space when a large space is not needed, affecting the overall aesthetics and practicality of the vehicle.

[0006] Limited application in multiple scenarios: Existing trunk designs mainly focus on storage functions and lack support for other scenarios, which limits the user experience and the vehicle's versatility. Summary of the Invention

[0007] This invention provides a multi-door telescopic trunk to solve the technical problem of inconvenient loading caused by the fixed space of existing car trunks.

[0008] The present invention provides a multi-door telescopic trunk, comprising: an outer box body connected to the vehicle body, having an opening at its rear end; The inner box is slidably fitted with the outer box and can be housed in the outer box or extend from the opening at the rear end of the outer box to at least partially expose the outer box, while the rear end of the inner box is closed. The inner box includes a bottom plate and a cover on the bottom plate. The cover includes an inner frame and a top cover, a tailgate, a left door, and a right door connected to the inner frame. At least one of the left door and the right door and the tailgate can be switched between open and closed states.

[0009] In one embodiment of the present invention, the cover is slidably connected to the outer box.

[0010] In one embodiment of the present invention, a cover driving mechanism is further included for driving the cover to extend from or retract from the outer box.

[0011] In one embodiment of the present invention, a cover guide mechanism is provided between the outer box and the cover, the cover guide mechanism being used to translate and guide the cover during the process of extending or retracting from the outer box.

[0012] In one embodiment of the present invention, the bottom plate is slidably connected to the bottom wall of the outer casing.

[0013] In one embodiment of the present invention, a base plate driving mechanism is further included, for driving the base plate to extend from or retract from the outer casing.

[0014] In one embodiment of the present invention, a bottom plate guide mechanism is provided between the outer box and the bottom plate, and the bottom plate guide mechanism is used to translate and guide the bottom plate during the process of extending or retracting from the outer box.

[0015] In one embodiment of the present invention, the top end of the tailgate is rotatably connected to the top cover, and a locking mechanism is provided between the bottom end of the tailgate and the bottom plate.

[0016] In one embodiment of the present invention, the top end of the left door is rotatably connected to the top cover, and a locking mechanism is provided between the bottom end or side end of the left door and the inner frame.

[0017] In one embodiment of the present invention, the top end of the right door is rotatably connected to the top cover, and a locking mechanism is provided between the bottom end or side end of the right door and the inner frame.

[0018] In one embodiment of the present invention, the inner frame includes a left column and a right column, the top ends of the left column and the right column are fixedly connected to the top cover, a locking mechanism is provided between the side end of the left door and the left column, and a locking mechanism is provided between the side end of the right door and the right column.

[0019] In one embodiment of the present invention, the inner frame includes two left columns and two right columns. The top ends of the left and right columns are fixedly connected to the top cover. A left bottom beam is fixedly connected between the bottom ends of the two left columns. A locking mechanism is provided between the bottom end of the left door and the left bottom beam. A right bottom beam is fixedly connected between the bottom ends of the two right columns. A locking mechanism is provided between the bottom end of the right door and the right bottom beam.

[0020] In one embodiment of the present invention, both the left door and the right door are gull-wing doors or eagle-wing doors.

[0021] In one embodiment of the present invention, the upward opening angle of the left door, the right door and the tail door is 1°-150°.

[0022] In one embodiment of the present invention, the left door, the right door and the tail door are each equipped with multiple image acquisition devices and acoustic sensors.

[0023] In one embodiment of the present invention, a control unit is provided inside the outer casing. The control unit is used to receive data from the acoustic sensor and the image acquisition device, and to control the extension or retraction of the inner casing, as well as to control the opening or closing of the tailgate, the left side door, and the right side door.

[0024] The beneficial effects of this invention are: 1. Improve loading convenience: By employing a "sleeve-like overlapping" outer and inner cargo box design, the trunk can extend and retract longitudinally within the vehicle. Both the side and tailgate doors of the inner cargo box can be opened, allowing users to access items from either side, making it particularly convenient for retrieving and placing large items. The inner cargo box uses a combination of a cover and a floor panel, which can operate independently. The tailgate can be opened without the cover extending, while the floor panel carrying luggage extends separately, reducing the number of times operators need to bend over and climb into the trunk, thus lowering the difficulty and physical exertion of operation. It also allows multiple people to simultaneously access items from the tailgate and side doors.

[0025] 2. Improve user experience in rainy weather: The retractable tailgate and side doors of the trunk combine to form a 270° surround opening on the extended inner trunk body. In rainy weather, users can stand under the open tailgate and side doors to retrieve items without needing an umbrella, effectively preventing rain from falling on them. They can then open the umbrella after retrieving their items, improving the convenience of using the trunk and the comfort of retrieving items from the trunk in the rain.

[0026] 3. Improve space utilization: When a large space is not required, the inner cargo box can be stored and hidden inside the outer cargo box, freeing up rear storage space, reducing the space occupied by the vehicle body, and improving the overall aesthetics and practicality of the vehicle. In addition, the retractable trunk can adjust the storage space according to actual needs, making space utilization more flexible and efficient.

[0027] 4. Enhance multi-scenario applications: The retractable trunk not only provides traditional storage but also serves unique purposes in various scenarios. For example, in its fully open mode, people can sit or lie down inside for activities like yoga, relaxation, sightseeing, or meditation. It can also function as a children's playground, providing more entertainment and leisure space for children to play. During outdoor activities, it can serve as a private space or camping platform, enhancing the user experience. In its stall mode, the inner compartment can be extended and fully opened, allowing for the storage of items or tools. The side doors and tailgate can also be used to hang goods or decorations, creating a personalized mobile shop and increasing the vehicle's versatility.

[0028] The present invention also provides a vehicle comprising a multi-door retractable trunk as described above. Such a vehicle has a retractable trunk, making it more convenient to retrieve items from the trunk and increasing its functionality. When the inner trunk is extended, the vehicle can be used in various scenarios such as leisure, entertainment, rest, display, and outdoor activities, thus enhancing its versatility. The extended inner trunk also increases the vehicle's interior space, allowing it to carry more and larger items, improving its loading capacity. Attached Figure Description

In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0033] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. The drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0034] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the invention. However, it will be apparent to those skilled in the art that embodiments of the invention may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the invention.

[0035] Please see Figure 1 , Figure 1 A multi-door retractable trunk provided in one embodiment of the present invention includes: The outer casing 1 is connected to the vehicle body and has an opening at its rear end. In this embodiment, the outer casing 1 is preferably part of the rear end of the vehicle body and is connected to the vehicle body as a whole. The inner casing 2 slides with the outer casing 1 and can be housed inside the outer casing 1, or extend from the opening at the rear end of the outer casing 1 to at least partially expose the outer casing 1. The rear end of the inner casing 2 is closed. Figure 4As shown, the inner box 2 includes a top cover 201, a bottom plate 203, a tailgate 202, a left side door 204, a right side door 205, and an inner frame. The top cover 201 is slidably connected to the inner side of the top wall of the outer box 1. The inner frame includes two left columns 206 and two right columns 207. The tops of the two left columns 206 and the two right columns 207 are fixedly connected to the top cover 201. A left bottom beam 208 is fixedly connected between the bottom ends of the two left columns 206, and a right bottom beam 209 is fixedly connected between the bottom ends of the two right columns 207. The bottom plate 203 is slidably connected to the bottom wall of the outer box 1, and the bottom plate 203 is located between the left bottom beam 208 and the right bottom beam 209, thus separating the bottom plate 203 from the inner frame. The top of the tailgate 202 is rotatably connected to the top cover 201. In this embodiment, a high-strength alloy hinge is preferably used for the connection. The bottom of the tailgate 202 can be locked to the bottom plate 203. The top of the left door 204 is rotatably connected to the top cover 201. In this embodiment, a hinge is preferably used for the connection. The bottom of the left door 204 can be locked to the left bottom beam 208. The top of the right door 205 is rotatably connected to the top cover 201. In this embodiment, a hinge is preferably used for the connection. The bottom of the right door 205 can be locked to the right bottom beam 209.

[0036] In this embodiment, the outer box 1 adopts the existing vehicle body rear structure, so that the main body size structure remains unchanged. By setting a sliding and retractable inner box 2 inside the outer box 1, combined with... Figure 2 As shown, the inner compartment 2 can be stored in the outer compartment 1. When large items need to be loaded, the trunk space needs to be expanded, or items need to be retrieved from the trunk, the inner compartment 2 extends out, thus expanding the usable space of the trunk. The inner compartment 2 adopts a partitioned movable structure. Its top cover 201, left side door 204, right side door 205, tailgate 202, and inner frame are connected to form the compartment body, and the bottom plate 203 is the compartment bottom. Both the compartment bottom and the compartment body can slide and extend relative to the outer compartment 1.

[0037] The locking mechanism between the tailgate 202 and the bottom plate 203 is an electromagnetic lock. The tailgate 202 and the top cover 201 are connected by a hinge. In this embodiment, the tailgate 202 is preferably an electric tailgate 202, and its electric drive mechanism adopts existing technology. One end of the electric drive structure is located on the left pillar 206 and the right pillar 207. Figure 3 As shown, when the tailgate 202 is opened, the inner box 2 can be folded up in the same way as the trunk retrieval operation in the prior art. At this time, the floor 203 can also be extended from the outer box 1, so that the floor 203 forms a suspended platform at the rear of the vehicle, which can be used for placing items, sitting, lying down and other operations.

[0038] The top cover 201 serves as the sliding connection between the box body and the outer box body 1, and also as the mounting support structure for the tailgate 202, left door 204, and right door 205. When the inner box body 2 extends, the box body can extend over the bottom plate 203 to the outside of the rear end of the vehicle, or the box body and the bottom plate 203 can extend together to the outside of the rear end of the vehicle. When the box body extends alone, it can form an extended cover at the rear of the vehicle. In this embodiment, the locking mechanisms between the left door 204 and the left bottom beam 208, and between the right door 205 and the right bottom beam 209, are preferably electromagnetic locks. When the box body and the bottom plate 203 extend together, and then the tailgate 202, the left door 204, and the right door 205 are opened, items on the bottom plate 203 can be retrieved simultaneously from three directions around the rear of the vehicle (270°), enabling multiple people to retrieve and place items at the same time, providing a larger operating space and higher loading and unloading efficiency. At this time, the open left door 204, right door 205 and tail door 202 can also be used to keep out rain.

[0039] For example, this embodiment also includes a base plate 203 driving mechanism for driving the base plate 203 to extend or retract from the outer housing 1. Preferably, the base plate 203 driving mechanism is installed at the bottom of the outer housing 1 and can be an electric push rod, a cylinder rod, or a hydraulic rod. In this embodiment, an electric push rod is preferred, thus ensuring smooth and reliable driving of the base plate 203. Furthermore, when used in new energy vehicles, it can be directly driven by the vehicle's power energy, resulting in greater energy savings.

[0040] For example, in this embodiment, a bottom plate 203 guiding mechanism is provided between the outer casing 1 and the bottom plate 203. The bottom plate 203 guiding mechanism is used to guide the bottom plate 203 to extend or retract from the outer casing 1. In this embodiment, the preferred bottom plate 203 guiding mechanism is two sets of parallel high-strength aluminum alloy guide rails installed between the outer casing 1 and the bottom plate 203. It should be emphasized that each set of guide rails here includes a guide rail body and a sliding body. The guide rail body is bolted to the outer casing 1, and the sliding body is bolted to the bottom plate 203.

[0041] For example, this embodiment also includes a top cover 201 driving mechanism for driving the top cover 201 to extend or retract from the outer housing 1. Preferably, the top cover 201 driving mechanism is installed on the top of the outer housing 1 and can be an electric push rod, a cylinder rod, or a hydraulic rod. In this embodiment, an electric push rod is preferred, thus ensuring smooth and reliable driving of the top cover 201. Furthermore, when used in new energy vehicles, it can be directly driven by the vehicle's power energy, resulting in greater energy savings.

[0042] For example, in this embodiment, a top cover 201 guide mechanism is provided between the outer casing 1 and the top cover 201. The top cover 201 guide mechanism is used to guide the top cover 201 to extend or retract from the outer casing 1. In this embodiment, the preferred top cover 201 guide mechanism is two sets of parallel high-strength aluminum alloy guide rails installed between the outer casing 1 and the top cover 201. It should be emphasized that each set of guide rails here also includes a guide rail body and a sliding body. The guide rail body is bolted to the outer casing 1, and the sliding body is bolted to the top cover 201.

[0043] For example, in this embodiment, a high-strength aluminum alloy guide rail is provided between the left bottom beam 208 and the right bottom beam 209 and the outer box 1, in order to reduce the friction between the inner frame and the outer box 1, improve the smoothness of the expansion and contraction of the inner box 2, and provide a certain support for the inner box 2. The guide rail here also includes a guide rail body and a sliding body. The guide rail body is bolted to the outer box 1, and the sliding body is bolted to the left bottom beam 208 and the right bottom beam 209, or the left bottom beam 208 and the right bottom beam 209 can be used as sliding bodies in cooperation with the guide rail body by slotting.

[0044] For example, in this embodiment, both the left door 204 and the right door 205 are gull-wing doors or falcon-wing doors. Gull-wing doors or falcon-wing doors can open and close vertically, occupying less lateral space during operation, which is more conducive to opening the inner box 2 in relatively narrow spaces. In this embodiment, the main structure and drive method of the gull-wing door or falcon-wing door adopt the main structure and drive technology of gull-wing doors / falcon-wing doors used in existing vehicle doors, such as electric push rod drive, hydraulic rod drive, cylinder rod drive, and the double pivot hinge used in falcon-wing doors, etc., which will not be elaborated here. Preferably, an electric push rod drive is adopted, and the power source for its drive is electric energy. When used in new energy vehicles, it can be directly driven by the vehicle's power source. In this embodiment, the left door 204 and the right door 205 are preferably made of carbon fiber composite material or other alternative lightweight high-strength materials.

[0045] For example, in this embodiment, the upward opening angle of the left door 204, the right door 205, and the tailgate 202 is 1°-150°. In this embodiment, the preferred opening angle is 120°, which allows for a larger operating space after opening, which is more conducive to improving loading and unloading efficiency and providing better rain protection.

[0046] For example, in this embodiment, a locking mechanism is provided between the side end of the left door 204 facing the left column 206 and the left column 206. The locking mechanism is an electromagnetic lock. Similarly, a locking mechanism is provided between the side end of the right door 205 facing the right column 207 and the right column 207. This locking mechanism is also an electromagnetic lock. This structure allows the left door 204 and the right door 205 to be locked to the inner frame only through their sides. The inner frame can be optimized by eliminating the left bottom beam 208 and the right bottom beam 209, making the structure of the inner frame simpler.

[0047] For example, in this embodiment, multiple image acquisition devices and acoustic sensors are provided on the sides of the left door 204, right door 205, and tailgate 202. The acoustic sensors monitor the opening environment of the left door 204, right door 205, or tailgate 202 in real time, detecting environmental changes and preventing hand pinching and collisions. The image acquisition devices assist the acoustic sensors, improving the accuracy of environmental monitoring. Preferably, in this embodiment, the image acquisition devices are cameras, and the acoustic sensors are ultrasonic sensors. At least three cameras and at least six ultrasonic sensors are provided to achieve omnidirectional monitoring.

[0048] For example, in this embodiment, a control unit is provided inside the outer box 1. The control unit is used to receive data from acoustic sensors and cameras, and to control the extension or retraction of the top cover 201 and the bottom plate 203, as well as the opening or closing of the tailgate 202, the left door 204, and the right door 205. The control unit is connected to the acoustic sensors, cameras, the drive mechanism of the top cover 201, the drive mechanism of the bottom plate 203, the electromagnetic lock, and the electric push rod. It receives data from the acoustic sensors and cameras and issues control commands to control the extension or retraction of the inner box 2, the opening or closing of the left door 204, the opening or closing of the right door 205, and the opening or closing of the tailgate 202. The control unit is also connected to the vehicle host system to receive operation signals issued by the driver through the host system. In this embodiment, the control unit preferably takes the NXP MPC574xP series as an example. The following is an application example of its intelligent trunk control: Data processing: The high-performance kernel can quickly process data from ultrasonic sensors and cameras, enabling real-time environmental monitoring and obstacle detection.

[0049] Control Decision: The embedded microprocessor can adjust the opening or closing angle and speed of the left door 204, right door 205 and tail door 202 through the control unit based on sensor data to prevent hand pinching and collision accidents.

[0050] Security protection: Multiple security features such as ECC (Error Correction and Check) and watchdog timer ensure system stability and reliability.

[0051] Through real-time monitoring by ultrasonic sensors and cameras, the control unit can adjust the opening or closing angle and speed of the gull-wing side doors and the rear tailgate in a timely manner to prevent hand pinching and collision accidents, thereby improving user safety. It can also be used as an intelligent driving assistance device when the car is in motion, or as an environmental detection assistance device in sentry mode when stationary.

[0052] The workflow of this embodiment is as follows: Activating the retractable trunk function: The user activates the trunk retractable function via the vehicle system or a manual button. Upon receiving the activation signal, the control unit activates the electric push rod of the top cover 201 drive mechanism or the bottom plate 203 drive mechanism. The electric push rod pushes the top cover 201 or the bottom plate 203 to slide along the guide rail, causing the inner compartment 2 to extend outward or retract.

[0053] Door opening or closing: The user initiates the door opening or closing function via the vehicle system or a manual button. Upon receiving the opening or closing signal, the control unit activates the drive mechanism of the left door 204, right door 205, or tailgate 202, such as an electric push rod. The electric push rod pushes the two side doors or tailgate 202, causing them to open or close according to a preset angle and sequence.

[0054] Ultrasonic sensors and cameras monitor the surrounding environment in real time. If an obstacle or human body approaches, the control unit will immediately stop the door's movement to prevent hands from being pinched or collided.

[0055] Environmental monitoring: Ultrasonic sensors and cameras continuously monitor the environment around the trunk. The data is transmitted to the control unit, which adjusts the opening or closing angle and speed of the doors according to environmental changes.

[0056] Locking mechanism: When the left door 204, right door 205, or tailgate 202 is fully opened or closed, the electromagnetic lock automatically locks to ensure the stability and security of the doors. Users can unlock the doors via the vehicle system or a manual button to reopen or close them again.

[0057] With its intelligent control unit and drive system, users can easily operate the trunk's extension and retraction, as well as the opening and closing of the doors, simplifying the usage process and improving ease of operation and comfort. Furthermore, the multi-angle access design supports simultaneous operation by multiple people, enhancing loading and unloading efficiency.

[0058] This invention, through its sleeve-type overlapping structure of an outer box 1 and an inner box 2, and the 270° opening design of the inner box 2, combined with gull-wing or falcon-wing door designs, not only solves the problems of inconvenient loading and rainy weather use caused by the fixed space in existing trunk designs, but also significantly improves space utilization and the possibility of multi-scenario applications. Through the cooperation of an intelligent control unit and an environmental monitoring system, user safety during use is further enhanced, making the intelligent telescopic multi-door trunk a highly integrated, multifunctional, and user-friendly automotive accessory.

[0059] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
