The following refers to Figures 1-6 The opening and closing system 101 of the front hatch according to the embodiments of the present application is described, which can realize the opening, closing and hovering of the front hatch 1 at any open position, greatly enhancing the flexibility and applicability of the front hatch 1, and meeting the use requirements of different users in different scenarios.

[0035] As shown in Figures 1-6 According to the opening and closing system 101 of the front hatch according to an embodiment of the present application, it comprises: a front hatch 1, an electric opening and closing structure, and a control module 2.

[0036] The electric opening and closing structure is connected with the front hood 1, so that the electric opening and closing structure can drive the front hood 1 to move when the electric opening and closing structure moves, and the opening and closing of the front hood 1 is realized.

[0037] Further, the control module 2 is electrically connected with the electric opening and closing structure, the control module 2 is used for controlling the electric opening and closing structure to drive the front hood 1 to move, and the front hood 1 is adapted to be suspended to any opening position.

[0038] Specifically, the control module 2 is the control center of the opening and closing system 101 of the front hood, the control module 2 is electrically connected with the electric opening and closing structure, that is, the control module 2 can transmit signals or currents with the electric opening and closing structure, so as to realize the control of the control module 2 on the electric opening and closing structure. When the control module 2 sends an opening and closing signal to the electric opening and closing structure, and the electric opening and closing structure receives the opening and closing signal, the electric opening and closing structure can drive the front hood 1 to move, that is, the electric opening and closing structure moves to drive the front hood 1 to move, so as to realize the opening and closing movement of the front hood 1 away from or close to the vehicle body.

[0039] And the control module 2 can suspend the front hood 1 to any opening position, that is, in the process of the movement of the front hood 1, the control module 2 can also send a suspension signal to the electric opening and closing structure, and the electric opening and closing structure stops moving after receiving the suspension signal, and cannot continue to drive the front hood 1 to move, so that the front hood 1 stops moving and can be suspended at any opening position. Therefore, the suspension of the front hood 1 at any opening position is realized, that is, the front hood 1 can be suspended at any opening angle from 0° to the maximum opening angle, which greatly enhances the flexibility and applicability of the front hood 1, and can meet the use requirements of different users in different scenes.

[0040] According to the opening and closing system 101 of the front hood of the embodiment of the utility model, the control module 2 controls the electric opening and closing structure to drive the front hood 1 to move, realizes the opening, closing and suspension of the front hood 1 at any opening position, greatly enhances the flexibility and applicability of the front hood 1, and can meet the use requirements of different users in different scenes.

[0041] In some embodiments, as shown in Figures 2-4 The electric opening and closing structure is configured as an electric spring 3, the electric spring 3 includes a first electric driving part 31, a fixed shell 32 and a telescopic part 33, and the electric spring 3 can perform telescopic movement to realize the accurate and stable opening and closing movement of the front hood 1.

[0042] The first electric driving member 31 is electrically connected with the control module 2, that is, the first electric driving member 31 can transmit signals or electric current with the control module 2, when the first electric driving member 31 receives the opening signal, the closing signal or the hovering signal sent by the control module 2, the first electric driving member 31 starts to work and performs corresponding operation. The fixed shell 32 is used for mounting the first electric driving member 31 and the telescopic member 33, the telescopic member 33 is movable relative to the fixed shell 32, and the fixed shell 32 is adapted to be connected with the vehicle body to ensure stable mounting of the fixed shell 32, thereby providing stable support and fixation for the electric spring 3, and further ensuring stable movement of the telescopic member 33.

[0043] Further, the first electric driving member 31 is used for driving the telescopic member 33 to extend or retract relative to the fixed shell 32 to drive the front hood 1 to move, that is, the first electric driving member 31 is a power source of the electric spring 3, and can provide power for the telescopic member 33 to drive the telescopic member 33 to extend or retract relative to the fixed shell 32, one end of the telescopic member 33 is connected with the front hood 1, so that the telescopic member 33 can drive the front hood 1 to move when the telescopic member 33 extends or retracts. For example, when the telescopic member 33 extends relative to the fixed shell 32, that is, the telescopic member 33 gradually moves away from the fixed shell 32, the telescopic member 33 pushes the front hood 1 to gradually move away from the vehicle body, thereby realizing opening of the front hood 1, when the front hood 1 moves to the maximum opening angle, the telescopic member 33 stops extending, that is, the telescopic member 33 also moves to the maximum stroke at the same time, correspondingly, when the telescopic member 33 retracts relative to the fixed shell 32, that is, the telescopic member 33 gradually approaches and retracts into the fixed shell 32, the telescopic member 33 drives the front hood 1 to gradually approach the vehicle body, thereby realizing closing of the front hood 1, the front hood 1 returns to the initial position, at this time, the telescopic member 33 stops retracting, that is, the telescopic member 33 also returns to the initial state.

[0044] Specifically, in practice, when the first electric driving member 31 receives the opening signal sent by the control module 2, the first electric driving member 31 drives the telescopic member 33 to extend relative to the fixed shell 32 to drive the front hood 1 to move, at any moment during opening of the front hood 1, that is, at any moment when the telescopic member 33 extends, the control module 2 can send the hovering signal to the first electric driving member 31, the first electric driving member 31 stops driving after receiving the hovering signal, so that the telescopic member 33 stops extending and keeps the existing extension length, at this time, the total moment of the electric spring 3 can balance the total moment of resistance in the opening direction at any angle and in the closing direction, thereby realizing hovering of the front hood 1 at the current position.

[0045] Correspondingly, when the first electric drive 31 receives the closing signal sent from the control module 2, the first electric drive 31 drives the telescopic member 33 to retract relative to the fixed shell 32 to drive the front hood 1 to perform a closing movement. At any moment during the closing of the front hood 1, that is, at any moment when the telescopic member 33 performs a retracting action, the control module 2 can also send a hovering signal to the first electric drive 31. After the first electric drive 31 receives the hovering signal, the first electric drive 31 stops driving, so that the telescopic member 33 stops the retracting action and maintains the existing retracted length. At this time, the total moment of the electric spring 3 can balance the total moment of resistance in the opening direction and the closing direction at any angle, so as to realize the hovering of the front hood 1 at the current position.

[0046] Therefore, by the arrangement of the electric spring 3, the opening and closing of the front hood 1 is realized accurately and stably, and is easy to control, thereby improving the convenience and efficiency of the opening and closing of the front hood 1. By the cooperation of the electric spring 3 and the control module 2, the front hood 1 can hover at any angle position during the opening and closing process, thereby greatly improving the flexibility and applicability of the front hood 1.

[0047] In some embodiments, as shown in Figure 3 and Figure 4 , the electric spring 3 further comprises a drive worm wheel 34 and a transmission screw rod 35. As shown in the left-right direction in FIG. 4, the drive worm wheel 34 is connected to the right end, that is, the output end of the first electric drive 31. In this way, when the first electric drive 31 starts to move, power can be transmitted to the drive worm wheel 34 to drive the drive worm wheel 34 to rotate.

[0048] Further, the drive worm wheel 34 is engaged with the transmission screw rod 35 and is used to drive the transmission screw rod 35 to rotate. The transmission screw rod 35 is threadedly engaged with the telescopic member 33 to drive the telescopic member 33 to extend or retract relative to the fixed shell 32.

[0049] That is, when the drive worm wheel 34 rotates, it can drive the transmission screw rod 35 to rotate, thereby transmitting power to the transmission screw rod 35. As shown in Figure 4 , the transmission screw rod 35 is arranged along the length direction of the fixed shell 32. The transmission screw rod 35 is provided with external threads. The telescopic member 33 is also arranged along the length direction of the fixed shell 32. The telescopic member 33 is hollow and the inner circumferential wall is provided with internal threads matched with the external threads. The telescopic member 33 is sleeved on the transmission screw rod 35. In this way, the transmission screw rod 35 is threadedly engaged with the telescopic member 33. When the transmission screw rod 35 rotates, it can drive the telescopic member 33 to move linearly along the transmission screw rod 35 to extend or retract from the fixed shell 32, thereby converting the rotary motion of the transmission screw rod 35 into the linear motion of the telescopic member 33, realizing the extension and retraction of the telescopic member 33 relative to the fixed shell 32, and further realizing the opening and closing of the front hood 1.

[0050] Specifically, as shown in Figure 4When the telescopic member 33 moves from the left end to the right end of the transmission screw rod 35, it gradually extends out of the fixed shell 32, at this time, the extension length of the telescopic member 33 gradually increases, the total length of the electric spring 3 increases, until the telescopic member 33 moves to the right end of the transmission screw rod 35, the telescopic member 33 moves to the maximum stroke displacement, i.e. reaches the maximum extension length, and the total length of the electric spring 3 reaches the maximum, Figure 4 When the telescopic member 33 moves from the left end to the right end of the transmission screw rod 35, it gradually extends out of the fixed shell 32, at this time, the extension length of the telescopic member 33 gradually increases, the total length of the electric spring 3 increases, until the telescopic member 33 moves to the right end of the transmission screw rod 35, the telescopic member 33 moves to the maximum stroke displacement, i.e. reaches the maximum extension length, and the total length of the electric spring 3 reaches the maximum,

[0051] In actual design, the first electric driving member 31 can be configured as a driving motor, and the telescopic member 33 can be configured as a nut pipe.

[0052] In some embodiments, the first electric driving member 31 is configured to drive the front hood 1 to open when rotating in a first direction, and is configured to drive the front hood 1 to close when rotating in a second direction, the first direction and the second direction are opposite, and the first direction and the second direction can be clockwise and counterclockwise, for example, the first direction is clockwise and the second direction is counterclockwise.

[0053] Therefore, when the first electric driving member 31 rotates clockwise, it can drive the telescopic member 33 to extend relative to the fixed shell 32, thereby driving the front hood 1 to open, and when the first electric driving member 31 rotates counterclockwise, it can drive the telescopic member 33 to retract relative to the fixed shell 32, thereby driving the front hood 1 to close, so that the opening and closing of the front hood 1 is realized by rotating the first electric driving member 31 in two opposite directions, which is flexible and convenient, and the control is simple.

[0054] And the first electric driving member 31 is configured to selectively stop rotating and suspend the front hood 1 to an arbitrary open position when rotating to an arbitrary position.

[0055] That is, in the process of opening the front hood 1, the first electric drive 31 rotates to any position along the first direction and makes the telescopic member 33 extend to any length, when the front hood 1 is opened to any angle, the first electric drive 31 can stop rotating, so that the telescopic member 33 stops extending, the front hood 1 stops opening, thereby realizing the hovering of the front hood 1 at any opening angle in the opening process. Of course, the first electric drive 31 can also not stop rotating in the process of opening the front hood 1, until the front hood 1 moves to the maximum opening angle, and automatically stops rotating. Similarly, in the process of closing the front hood 1, the first electric drive 31 rotates to any position along the second direction and makes the telescopic member 33 retract to any length, when the front hood 1 is closed to any angle, the first electric drive 31 can stop rotating, so that the telescopic member 33 stops retracting, the front hood 1 stops closing, thereby realizing the hovering of the front hood 1 at any opening angle in the closing process.

[0056] Therefore, through the arbitrary stop of the first electric drive 31 in the rotating process, the precise hovering of the front hood 1 at any opening position is realized, that is, the front hood 1 is not completely opened and closed, the degree of automation of the front hood 1 is improved, and the user experience is improved.

[0057] In some embodiments, a fixed cavity 321 is formed in the fixed shell 32, the first electric drive 31 is installed in the fixed cavity 321, and a part of the telescopic member 33 is located in the fixed cavity 321 and another part is located outside the fixed cavity 321.

[0058] Specifically, as shown in Figure 4 The fixed shell 32 is cylindrical in structure, and can also be rectangular or other shapes, etc. The inside of the fixed shell 32 is hollow to form the fixed cavity 321, and the first electric drive 31 is installed in the fixed cavity 321 to ensure stable installation of the first electric drive 31 and protect the first electric drive 31 from damage. When the telescopic member 33 is in the initial state, i.e., without telescopic movement, the left end of the telescopic member 33 is located in the fixed cavity 321, and a small part of the right end is located outside the fixed cavity 321, so as to facilitate the connection of the right end of the telescopic member 33 with the front hood 1 and drive the front hood 1 to move. In practice, when the telescopic member 33 extends, the right end of the telescopic member 33 gradually moves away from the fixed shell 32, until the left end of the telescopic member 33 moves to the right end position of the fixed shell 32, and the telescopic member 33 is completely extended. When the telescopic member 33 retracts, the right end of the telescopic member 33 gradually approaches the fixed shell 32, until the right end of the telescopic member 33 moves to the right end position of the fixed shell 32, and the telescopic member 33 is completely retracted into the fixed cavity 321.

[0059] In some embodiments, the opening and closing system 101 of the front hatch further comprises an electric lock assembly 4, which is electrically connected with the control module 2, and the control module 2 is further configured to control the electric lock assembly 4 to selectively unlock or lock the front hatch 1.

[0060] Specifically, the electric lock assembly 4 is configured to realize the unlocking or locking of the front hatch 1, and the front hatch 1 can only be opened when it is in the unlocked state, and the front hatch 1 cannot be opened when it is in the locked state. Wherein, the electric lock assembly 4 is electrically connected with the control module 2, that is, the electric lock assembly 4 and the control module 2 can output current or signal, when the electric lock assembly 4 receives the unlocking signal sent by the control module 2, the control electric lock assembly 4 can unlock the front hatch 1 and send the unlocking feedback signal to the control module 2, and the control module 2 receives the unlocking feedback signal and continues to send the opening signal to the electric spring 3, thereby realizing the opening of the front hatch 1.

[0061] And when the electric lock assembly 4 receives the locking signal sent by the control module 2, the control electric lock assembly 4 can lock the front hatch 1.

[0062] Therefore, through the cooperation of the electric lock assembly 4 and the control module 2, the front hatch 1 is selectively unlocked or locked, which improves the operation convenience and safety of the opening and closing system 101 of the front hatch, and prevents the front hatch 1 from being opened accidentally.

[0063] In some embodiments, as shown in Figure 6 The electric lock assembly 4 comprises a lock tongue 41, an electric dissolution structure 42 and an electric suction structure 43, the lock tongue 41 is configured to selectively unlock or lock the lock catch of the front hatch 1, that is, when the lock tongue 41 is in the locked state, it is tightly connected with the lock catch of the front hatch 1, and when the lock tongue 41 is in the unlocked state, it is separated from the lock catch of the front hatch 1.

[0064] Further, the electric dissolution structure 42 is power connected with the lock tongue 41 to drive the lock tongue 41 to unlock the lock catch, that is, the electric dissolution structure 42 can drive the lock tongue 41 to perform the unlocking action, so that the lock tongue 41 is separated from the lock catch of the front hatch 1, thereby realizing the unlocking function of the front hatch 1; the electric suction structure 43 is power connected with the lock tongue 41 to drive the lock tongue 41 to lock the lock catch, that is, the electric suction structure 43 can drive the lock tongue 41 to perform the locking action, so that the lock tongue 41 is tightly connected with the lock catch of the front hatch 1, thereby realizing the locking function of the front hatch 1.

[0065] Therefore, by connecting or separating the lock tongue 41 and the lock catch of the front hatch 1, the unlocking and locking functions of the front hatch 1 are realized, so that the user can conveniently open or close the front hatch 1, and at the same time ensure that the front hatch 1 can be firmly locked when needed, thereby improving the reliability and safety of the front hatch 1.

[0066] In some embodiments, as shown in Figure 5 and Figure 6 The electrolytic structure 42 includes an electrolytic pull wire 421 and a locking arm 422, the electrolytic pull wire 421 is used to drive the locking arm 422 to rotate, Figure 6 One end of the electrolytic pull wire 421 is connected with the locking arm 422, so that when electrolysis is performed, the electrolytic pull wire 421 can pull the locking arm 422 to rotate, and the locking arm 422 pushes the lock tongue 41 to unlock, that is, the locking arm 422 can contact the lock tongue 41 to push the lock tongue 41 to rotate in one direction (clockwise in the figure) when rotating, so that the lock tongue 41 is separated from the lock catch, thereby achieving the unlocking of the lock tongue 41, and further achieving the unlocking of the front hatch cover 1.

[0067] In other embodiments, as shown in Figure 5 and Figure 6 The electric attraction structure 43 includes an attraction pull wire 431 and an attraction rocker arm 432, the attraction pull wire 431 is used to drive the attraction rocker arm 432 to rotate, Figure 6 One end of the attraction pull wire 431 is connected with the attraction rocker arm 432, so that when attraction is performed, the attraction pull wire 431 can pull the attraction rocker arm 432 to rotate, and the attraction rocker arm 432 pushes the lock tongue 41 to lock, that is, the attraction rocker arm 432 can contact the lock tongue 41 to push the lock tongue 41 to rotate in the other direction (counterclockwise in the figure) when rotating, so that the lock tongue 41 is connected with the lock catch, thereby achieving the locking of the lock tongue 41, and further achieving the locking of the front hatch cover 1.

[0068] In actual design, as shown in Figure 6 When unlocked, the upper end of the attraction rocker arm 432 is spaced apart from the lock tongue 41 by a certain distance, and during the attraction process, when the attraction pull wire 431 pulls the attraction rocker arm 432 to rotate, the attraction rocker arm 432 is lifted to contact the lock tongue 41 to push the lock tongue 41 to rotate in the other direction (counterclockwise in the figure), thereby achieving attraction.

[0069] In some embodiments, as shown in Figure 5 The electric lock assembly 4 further includes an electric lock actuator 44 connected with the electrolytic pull wire 421 and the attraction pull wire 431 respectively, for driving the electrolytic pull wire 421 and the attraction pull wire 431 to move respectively.

[0070] Therefore, the electrolytic pull wire 421 and the attraction pull wire 431 are driven by the electric lock actuator 44 to perform contraction movement to drive the locking arm 422 and the attraction rocker arm 432 to move, thereby achieving the unlocking and locking of the lock tongue 41, which is flexible and convenient, and has high reliability.

[0071] It should be noted that when the current hatch 1 moves to the half-lock position of the electric lock assembly 4, the electric lock assembly 4 starts to work and performs the suction action to drive the front hatch 1 to close to the full-lock position.

[0072] In actual design, the electric lock actuator 44 can be electrically connected with the control module 2, so that the electric lock actuator 44 can receive the unlocking signal or locking signal sent by the control module 2, so that the electric lock actuator 44 can drive the electric pull wire 421 or the suction pull wire 431 to move. In addition, a driving motor can be arranged in the electric lock actuator 44 to drive the electric pull wire 421 or the suction pull wire 431 to move through the driving motor. Of course, a mechanical opening pull cable can also be arranged in the electric lock assembly 4, and the user can also manually open the front hatch 1 by using the opening pull cable, so that when the electric lock assembly 4 fails, the front hatch 1 can still be opened.

[0073] In some embodiments, the opening and closing system 101 of the front hatch further includes a control switch 5, which is electrically connected with the control module 2, and the control module 2 is adapted to control the electric opening and closing structure or the electric lock assembly 4 to act according to the operation instruction of the control switch 5.

[0074] Specifically, the control switch 5 can be arranged at the front of the vehicle 100 for the user to operate conveniently. The control switch 5 and the control module 2 can transmit current or signals. When the user needs to open the front hatch 1, the control switch 5 can be pressed or clicked. At this time, the control module 2 receives the opening instruction sent by the control switch 5 and outputs the unlocking signal to the electric lock assembly 4. The electric lock assembly 4 works to realize the unlocking of the front hatch 1. After the front hatch 1 is unlocked, the unlocking signal is fed back to the control module 2. After the control module 2 receives the feedback unlocking signal, the opening signal is output to the electric opening and closing structure. After the electric opening and closing structure receives the opening signal, it starts to work to drive the front hatch 1 to move. During the opening movement of the front hatch 1, the user can press or click the control switch 5 again to input the hovering instruction to the control module 2. After the control module 2 receives the hovering instruction, the hovering signal is output to the electric opening and closing structure. The electric opening and closing structure stops driving the front hatch 1 to move, so that the front hatch 1 hovers at the current position.

[0075] When the user presses or clicks the control switch 5 again, the closing instruction can be input to the control module 2. After the control module 2 receives the closing instruction, the closing signal is output to the electric opening and closing structure. After the electric opening and closing structure receives the closing signal, it starts to work to drive the front hatch 1 to move. During the closing movement of the front hatch 1, the user can press or click the control switch 5 again to input the hovering instruction to the control module 2. After the control module 2 receives the hovering instruction, the hovering signal is output to the electric opening and closing structure. The electric opening and closing structure stops driving the front hatch 1 to move, so that the front hatch 1 hovers at the current position.

[0076] Therefore, the input of the operation instruction is realized by controlling the switch 5 and is transmitted to the control module 2, so that corresponding control of the control module 2 is realized, which is flexible and convenient, simple and easy to operate, and the experience of users is improved.
