Description

Technical Field

[0001] This application belongs to the field of automotive front trunk technology, and specifically relates to a liftable front trunk structure. Background Technology

[0002] As the automotive industry undergoes electrification and the market share of new energy vehicles gradually increases, along with customers' growing demand for vehicle storage functions, the need for and convenience of front trunk storage is also increasing. In particular, the smaller size of the electric motor in pure electric vehicles compared to the engine in non-pure electric vehicles, and the fact that pure electric vehicles do not require a transmission, makes it feasible to install a front trunk in the front cabin space of pure electric vehicles.

[0003] However, due to the limitations of traditional hood design and pedestrian protection, the front trunk cannot have the same opening method as the rear trunk. Moreover, most front trunks on the market are fixed top openings. When taking items out of this type of front trunk, you need to go around the top of the front grille, which will result in inconvenient actions such as obstructed vision, leaning forward, and bending over. Therefore, the front trunk is not as convenient to use as the rear trunk.

[0004] Therefore, this application proposes a liftable front trunk structure. Summary of the Invention

[0005] To address the aforementioned issues, this application provides a liftable front trunk structure that allows the front trunk to be raised and lowered, making it more convenient to retrieve items from the front trunk and thus improving the practicality of the front trunk.

[0006] A liftable front trunk structure includes a front trunk body, a front trunk guide rail plate, a front trunk guide groove assembly, a front trunk lifting actuator assembly, and a sliding bracket plate; the front trunk guide rail plates are fixedly connected to both side walls of the front trunk body; the front trunk body is slidably connected to the front trunk guide groove assembly via the front trunk guide rail plates; the sliding bracket plate is mounted on the rear wall of the front trunk body via an installation structure; the sliding bracket plate moves up and down via the front trunk lifting actuator assembly.

[0007] Preferably, the front trunk guide channel assembly includes a first guide channel body; a groove is formed on the side wall of the first guide channel body; a first support portion and a second support portion are respectively fixed to both sides of the opening of the groove; the first support portion and the second support portion are arranged in an arc shape, and the arc-shaped ends of the first support portion and the second support portion face into the groove; a third support portion is fixed to the inner side wall of the groove; the third support portion is arranged vertically, and the position of the third support portion corresponds to the position of the opening formed by the first support portion and the second support portion.

[0008] Preferably, the first guide groove body, the first support part, the second support part, and the third support part are integrated; the first support part, the second support part, and the third support part are all made of soft EPDM material.

[0009] Preferably, the mounting structure includes an L-shaped mounting plate; a set of first mounting holes are provided on the sliding bracket plate; the sliding bracket plate is mounted on the side wall of the L-shaped mounting plate by bolts passing through the first mounting holes; the L-shaped mounting plate is fixed on the side wall and bottom wall of the front trunk body, and the L-shaped mounting plate and the front trunk body are integrally formed.

[0010] The front trunk body is connected to the front trunk guide rail plate and the front trunk guide groove assembly to provide guidance and support when the front trunk body moves up and down. The first support part, the second support part and the third support part are all made of soft EPDM material, which can be interference fit with the front trunk guide rail plate. This can provide sufficient support for the front trunk guide rail plate and absorb the vibration of the front trunk body. The force value of the front trunk lifting actuator assembly can be adjusted by adjusting the interference and angle between the first support part, the second support part and the third support part and the front trunk guide rail plate.

[0011] Preferably, the front trunk body has an opening slot, and the top and side walls of the opening slot are open; a front trunk cover is hinged to the opening side wall of the opening slot, and the cross-section of the front trunk cover is inverted L-shaped.

[0012] The lifting front trunk structure consists of a front trunk body, a front trunk guide rail plate, a front trunk guide groove assembly, a front trunk lifting actuator assembly, and a sliding bracket plate. The front trunk body is provided with an opening slot and an openable front trunk cover. Because the top and side walls of the opening slot are open, the visible area can be increased, making it more convenient for customers to store items.

[0013] Preferably, the front trunk lifting actuator assembly includes a sliding structure, a lifting actuator guide rail, and a lifting component; the sliding bracket plate is slidably connected to the lifting actuator guide rail via the sliding structure, and the sliding bracket plate moves up and down via the lifting component.

[0014] Preferably, the sliding structure includes a flange plate and a sliding block; a flange plate is provided on one side opening wall of the lifting actuator guide rail; an L-shaped opening groove is provided on the sliding block; the sliding block is slidably connected to the flange plate of the lifting actuator guide rail through the L-shaped opening groove; the sliding block is fixedly connected to the side wall of the sliding bracket plate.

[0015] Preferably, the lifting actuator guide rail and the flange plate are integrated; the sliding block and the sliding support plate are integrated.

[0016] Preferably, the lifting component includes a lifting actuator motor, a lifting actuator wire, a first pulley, and a second pulley; the first pulley and the second pulley are rotatably connected to the inner wall of the lifting actuator guide rail, and the first pulley is located above the second pulley; the driving part of the lifting actuator motor drives the lifting actuator wire to move, one end of the lifting actuator wire passes through the first pulley and is fixed to the top of the sliding support plate, and the other end of the lifting actuator wire passes through the second pulley and is fixed to the bottom of the sliding support plate.

[0017] Preferably, the lifting actuator motor is fixed to the vehicle body by a fixed bracket plate; a pair of second mounting holes are provided on the inner wall of the lifting actuator guide rail; the lifting actuator guide rail is installed on the vehicle body by bolts passing through the second mounting holes; a pair of mounting brackets are fixed to the upper side wall of the first guide groove body; the first guide groove body is installed on the vehicle body by bolts passing through the mounting brackets.

[0018] When the lifting actuator motor receives a lifting signal, it drives the lifting actuator wire to move. The lifting actuator wire connects to the sliding support plate via a first and second pulley fixed to the lifting actuator guide rail, thereby causing the sliding support plate to move along the flange plate of the lifting actuator guide rail. Since the sliding support plate is connected to the front trunk body via bolts and an L-shaped mounting plate, this enables the front trunk body to move up and down. When the lifting actuator wire passes through the first and second pulleys, the direction of the lifting actuator wire's movement is aligned with the direction of the flange plate in the lifting actuator guide rail. When the main body moves up and down, there are two movements: the front trunk guide rail plates on both sides of the front trunk main body move along the front trunk guide groove assembly, and the sliding bracket plate moves on the flange plate through the sliding block. Since the sliding bracket plate of the lifting actuator guide rail is the driving component, the movement trend of the front trunk guide groove assembly must be consistent with the movement trend of the sliding bracket plate on the flange plate through the sliding block in order to ensure that the front trunk main body moves up and down smoothly without jamming (the middle end of the lifting actuator wire is fixed to the drive part of the lifting actuator motor. The connection between the lifting actuator wire and the drive part of the lifting actuator motor is existing technology and will not be described in detail).

[0019] Compared with the prior art, this application has the following advantages: The opening slot of the front trunk body is designed with a front and top opening, which can reduce the blind spot and further improve the convenience of storing and retrieving items. Customers can raise the front trunk body to the optimal storage height with one click using an electronic button, eliminating the need for inconvenient actions such as leaning forward and bending over when storing or retrieving items in the front trunk body. This patent application uses a separate front trunk cover to seal the opening slot of the front trunk body, and the overall sealing effect is better than the solution of pressing the sealing strip on the sound insulation pad, which can provide a better sealed space for the front trunk body.

[0020] Other features and advantages of this application will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the application. The objectives and other advantages of this application may be realized and obtained by means of the structures pointed out in the description, claims and drawings. Attached Figure Description

[0025] A liftable front trunk structure includes a front trunk body 1, a front trunk guide rail plate 11, a front trunk guide groove assembly 2, a front trunk lifting actuator assembly 12, and a sliding bracket plate 13. The front trunk body 1 has front trunk guide rail plates 11 fixedly connected to both side walls. The front trunk body 1 is slidably connected to the front trunk guide groove assembly 2 via the front trunk guide rail plates 11. The sliding bracket plate 13 is mounted on the rear wall of the front trunk body 1 via an installation structure. The sliding bracket plate 13 moves up and down via the front trunk lifting actuator assembly 12. The front trunk guide channel assembly 2 includes a first guide channel body 21; a groove 22 is formed on the side wall of the first guide channel body 21; a first support portion 23 and a second support portion 24 are fixedly connected to both sides of the opening of the groove 22; the first support portion 23 and the second support portion 24 are arranged in an arc shape, and the arc-shaped ends of the first support portion 23 and the second support portion 24 face inwards into the groove 22; a third support portion 25 is fixedly connected to the inner side wall of the groove 22; the third support portion 25 is arranged vertically, and the position of the third support portion 25 corresponds to the position of the opening formed by the first support portion 23 and the second support portion 24. The first guide groove body 21, the first support part 23, the second support part 24 and the third support part 25 are integrated; the first support part 23, the second support part 24 and the third support part 25 are all made of soft EPDM material; The mounting structure includes an L-shaped mounting plate 3; a set of first mounting holes 31 are provided on the sliding bracket plate 13; the sliding bracket plate 13 is mounted on the side wall of the L-shaped mounting plate 3 by bolts passing through the first mounting holes 31; the L-shaped mounting plate 3 is fixed on the side wall and bottom wall of the front trunk body 1, and the L-shaped mounting plate 3 and the front trunk body 1 are integrated. like Figure 1 , 2 As shown in Figures 3 and 5, the front trunk body 1 is connected to the front trunk guide rail plate 11 and the front trunk guide groove assembly 2 to provide guidance and support when the front trunk body 1 moves up and down. The first support part 23, the second support part 24 and the third support part 25 are all made of soft EPDM material, which can be interference fit with the front trunk guide rail plate 11. This can provide sufficient support for the front trunk guide rail plate 11 and absorb the vibration of the front trunk body 1. The force value of the front trunk lifting actuator assembly 12 can be adjusted by adjusting the interference and angle between the first support part 23, the second support part 24 and the third support part 25 and the front trunk guide rail plate 11. The front trunk body 1 has an opening slot 34, and the top and side walls of the opening slot 34 are open; a front trunk cover 35 is hinged to the opening side wall of the opening slot 34, and the cross section of the front trunk cover 35 is inverted L-shaped. like Figure 3As shown, the lifting front trunk structure consists of a front trunk body 1, a front trunk guide rail plate 11, a front trunk guide groove assembly 2, a front trunk lifting actuator assembly 12, and a sliding bracket plate 13; wherein the front trunk body 1 is provided with an opening groove 34 and an openable front trunk cover 35. Since the top and side walls of the opening groove 34 are both open, the visible area can be increased, thus making it convenient for customers to store items. The front trunk lifting actuator assembly 12 includes a sliding structure, a lifting actuator guide rail 46, and a lifting component; the sliding bracket plate 13 is slidably connected to the lifting actuator guide rail 46 through the sliding structure, and the sliding bracket plate 13 moves up and down through the lifting component. The sliding structure includes a flange plate 32 and a sliding block 33; the flange plate 32 is provided on one side opening wall of the lifting actuator guide rail 46; the sliding block 33 is provided with an L-shaped opening groove 34; the sliding block 33 is slidably connected to the flange plate 32 of the lifting actuator guide rail 46 through the L-shaped opening groove 34; the sliding block 33 is fixed to the side wall of the sliding bracket plate 13. The lifting actuator guide rail 46 and the flange plate 32 are integrated; the sliding block 33 and the sliding bracket plate 13 are integrated. The lifting component includes a lifting actuator motor 4, a lifting actuator wire 41, a first pulley 42, and a second pulley 43; the first pulley 42 and the second pulley 43 are rotatably connected to the inner wall of the lifting actuator guide rail 46, and the first pulley 42 is located above the second pulley 43; the driving part of the lifting actuator motor 4 drives the lifting actuator wire 41 to move, one end of the lifting actuator wire 41 passes through the first pulley 42 and is fixed to the top of the sliding support plate 13, and the other end of the lifting actuator wire 41 passes through the second pulley 43 and is fixed to the bottom of the sliding support plate 13; The lifting actuator motor 4 is fixed to the vehicle body by a fixed bracket plate 44; a pair of second mounting holes 45 are provided on the inner wall of the lifting actuator guide rail 46; the lifting actuator guide rail 46 is installed on the vehicle body by bolts passing through the second mounting holes 45; a pair of mounting brackets 26 are fixed to the upper side wall of the first guide groove body 21; the first guide groove body 21 is installed on the vehicle body by bolts passing through the mounting brackets 26. like Figure 1 , 2As shown in Figures 3 and 4, when the lifting actuator motor 4 receives a lifting signal, it drives the lifting actuator wire 41 to move. The lifting actuator wire 41 is connected to the sliding support plate 13 via the first pulley 42 and the second pulley 43 fixed on the lifting actuator guide rail 46, thereby driving the sliding support plate 13 to move along the flange plate 32 of the lifting actuator guide rail 46. Since the sliding support plate 13 is connected to the front trunk body 1 via bolts and the L-shaped mounting plate 3, the front trunk body 1 can move up and down. When the lifting actuator wire 41 passes through the first pulley 42 and the second pulley 43, the direction of movement of the lifting actuator wire 41 is aligned with the direction of the flange plate 32 in the lifting actuator guide rail 46. The front trunk body 1 moves up and down, with two movements: the front trunk guide rail plates 11 on both sides of the front trunk body 1 move along the front trunk guide groove assembly 2, and the sliding bracket plate 13 moves on the flange plate 32 via the sliding block 33. Since the sliding bracket plate 13 of the lifting actuator guide rail component 46 is a driving component, the movement trend of the front trunk guide groove assembly 2 must be consistent with the movement trend of the sliding bracket plate 13 on the flange plate 32 via the sliding block 33 to ensure that the front trunk body 1 moves up and down smoothly without jamming. (The middle end of the lifting actuator wire 41 is fixed to the drive part of the lifting actuator motor 4. The connection between the lifting actuator wire 41 and the drive part of the lifting actuator motor 4 is existing technology and will not be described in detail.)

[0026] Working principle: The front trunk body 1 is connected to the sliding bracket plate 13 by bolts and an L-shaped mounting plate 3. The sliding bracket plate 13 can move up and down along the lifting actuator guide rail 46 under the drive of the lifting actuator motor 4, thereby realizing the up and down movement of the front trunk body 1. Front trunk guide rail plates 11 that cooperate with the front trunk guide groove assembly 2 are arranged on the left and right sides of the front trunk body 1 assembly. When the front trunk body 1 moves up and down, the front trunk guide rail plates 11 slide in the first guide groove body 21, thereby increasing the stability of the movement of the front trunk body 1. In addition, the opening groove 34 of the front trunk body 1 is in the form of a front opening plus a top opening, which can reduce the visual blind spot and further improve the convenience of storing and retrieving items.

[0027] Customers can raise the front trunk body 1 to the optimal height for storing and retrieving items with a single electronic button, eliminating the need for inconvenient actions such as leaning forward and bending over when storing or retrieving items in the front trunk body 1. This patent application uses a separate front trunk cover 35 to seal the opening slot 34 of the front trunk body 1, which provides a better overall sealing effect than the solution of pressing the sealing strip onto the sound insulation pad, thus providing a more enclosed space for the front trunk.

[0028] Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
