Description

Technical Field

[0001] The present invention relates to the technical field of vehicles, and in particular to an unlocking mechanism, a front cabin lock, a front bumper assembly and a vehicle. Background Art

[0002] The front cabin lock usually includes a primary locking mechanism, a primary unlocking mechanism, a secondary locking mechanism and a secondary unlocking mechanism. The primary unlocking mechanism is used to unlock the primary locking mechanism, and is usually located inside the cab, below the steering wheel. After the primary unlocking is completed, the engine hood pops up a certain distance. A certain distance is left between the engine hood and the front bumper, and then the secondary unlocking is performed.

[0003] Usually, the secondary unlocking mechanism is directly integrated with the secondary locking mechanism. When performing the secondary unlocking, the customer needs to reach into the engine cover and turn the secondary unlocking mechanism to unlock. When performing the secondary unlocking, due to the small space and the inability to observe the position of the secondary unlocking mechanism, the operation is difficult, which greatly reduces the user experience. Summary of the invention

[0004] An object of the present invention is to provide a new technical solution for an unlocking mechanism, a front cabin lock, a front bumper assembly and a vehicle. By changing the position where the unlocking mechanism is set, the operational difficulty of the user performing secondary unlocking is significantly reduced, thereby improving the user's experience.

The unlocking mechanism includes: a driving member, which can move relative to the front bumper assembly to switch between an initial position and an unlocking position; a first transmission member, and the driving member is transmission-connected to a secondary locking mechanism via the first transmission member. When the driving member is in the unlocking position, it can drive the secondary locking mechanism of the vehicle's front cabin lock to unlock the vehicle's engine hood.

[0006] By adopting the method of the present invention, the unlocking mechanism is integrated with the front bumper assembly so that at least a portion of the unlocking mechanism is exposed to the outside of the vehicle through the front bumper assembly, thereby facilitating the position of the secondary unlocking mechanism to be directly observed from the outside of the vehicle, thereby significantly increasing the space for manual operation of the unlocking mechanism, making it convenient for users to perform secondary unlocking of the front hood, and improving the user experience.

[0007] In one aspect of the present invention, a front cabin lock is provided. The front cabin lock includes a locking tongue disposed on one of the vehicle body and the engine hood; a lock body adapted to the locking tongue and disposed on the other of the vehicle body and the engine hood. The lock body includes a bottom plate, a primary locking mechanism and a secondary locking mechanism disposed on the bottom plate. The secondary locking mechanism is configured to form a locking cooperation with the locking tongue after the primary locking mechanism is unlocked. For the above-mentioned unlocking mechanism, the driving member can act on the locking hook to drive the locking hook to rotate, thereby driving the locking tongue to move for secondary unlocking.

[0008] In one aspect of the present invention, a front bumper assembly is provided, which integrates the above-mentioned unlocking mechanism.

[0009] In one aspect of the present invention, a vehicle is provided, which includes the above-mentioned front bumper assembly.

[0028] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0029] In the embodiments of the present invention, see Figure 1 and Figure 1a , Figure 2 , Figure 3 , for ease of understanding, Figure 1a Special General Figure 1 Part A is partially enlarged. The present invention provides an unlocking mechanism 1, which is integrated into a front bumper assembly 2 of a vehicle, and at least a part of the unlocking mechanism 1 is exposed to the outside of the vehicle through the front bumper assembly 2.

[0030] like Figure 3 and Figure 4 As shown, the unlocking mechanism 1 includes a driving member 11 and a first transmission member. The driving member 11 can move relative to the front bumper assembly 2, and the driving member 11 is connected to the secondary locking mechanism 3b through the first transmission member to drive the secondary locking mechanism 3b of the vehicle front cabin lock to unlock the engine hood.

[0031] in, Figure 1 and Figure 1a The front cabin lock in the embodiment includes a lock body 3 and a deadbolt (not shown in the figure). One of the lock body 3 and the deadbolt is arranged on the vehicle body, and the other is arranged on the engine cover.

[0032] See alsoFigure 5 and Figure 6 The lock body 3 includes a bottom plate 31, a primary locking mechanism 3a connected to one side of the bottom plate 31, and a secondary locking mechanism 3b connected to the other side of the bottom plate 31.

[0033] The secondary locking mechanism 3b includes a locking hook 32 and a first return spring 32a. The locking hook 32 is rotatably connected to the bottom plate 31 through a locking shaft 36. The first return spring 32a is connected between the locking hook 32 and the bottom plate 31. The locking hook 32 and the bottom plate 31 enclose a secondary locking cavity 3c, and the locking tongue can enter the secondary locking cavity 3c to cooperate with the secondary locking mechanism 3b for locking.

[0034] The locking hook 32 can rotate relative to the bottom plate 31 in Figure 5 the unlocking direction and the locking direction. The driving member 11 can act on the locking hook 32 to drive the locking hook 32 to rotate to drive the locking tongue to move for secondary unlocking. That is, when the locking hook 32 rotates in the unlocking direction, the locking tongue can be released from the secondary locking cavity 3c to cooperate with the locking hook 32 for secondary unlocking to unlock the engine hood.

[0035] One end of the first transmission member is in linkage cooperation with the locking hook 32, and the other end is in linkage cooperation with the driving member 11. The user can drive the locking hook 32 to rotate to unlock by driving the driving member 11 to move.

[0036] Specifically, the first transmission member includes a first wire rope assembly 4. Combining Figure 4 and Figure 5 as shown, the first wire rope assembly 4 includes a first wire rope body 41 and a steel skin sleeved outside the first wire rope body 41. Limiting blocks 41a and 41b are respectively arranged at both ends of the first wire rope body 41. The limiting blocks 41a and 41b can be spherical or other structures. The sizes of the limiting blocks 41a and 41b are larger than the radial size of the first wire rope body 41. The limiting blocks 41a and 41b respectively protrude from both ends of the steel skin. Plug heads 42a and 42b are arranged at both ends of the steel skin. The sizes of the plug heads 42a and 42b are smaller than the sizes of the limiting blocks 41a and 41b, so as to prevent the ends of the first wire rope body 41 from retracting into the steel skin.

[0037] Figure 3 In , the plug head 42a is fixed to the support structure 22 of the front bumper assembly 2, and the support structure 22 encloses a cavity. Combining Figure 3 and Figure 4 as shown, the limiting block 41a is located in the cavity, and a part of the driving member 11 also extends into the cavity and forms a linkage cooperation with the limiting block 41a. Figure 5 In , the plug head 42b is fixed to the bottom plate 31. The limiting block 41b protrudes from the plug head 42b and is in linkage cooperation with the locking hook 32.

[0038] Thus, when the driving member 11 moves, the driving member 11 pulls the locking hook 32 through the first transmission member, thereby driving the locking hook 32 to rotate in the unlocking direction to unlock.

[0039] In the manner of the present invention, the unlocking mechanism 1 is used to drive the locking hook 32 of the secondary locking mechanism 3b to rotate to release the locking tongue to unlock the engine hood. At the same time, by integrating the unlocking mechanism 1 with the front bumper assembly 2, at least a part of the unlocking mechanism 1 is exposed outside the vehicle by the front bumper assembly 2, so that the position of the secondary unlocking mechanism 1 can be directly observed from the outside of the vehicle, thereby significantly increasing the space for manual operation of the unlocking mechanism 1, facilitating the user to perform secondary unlocking of the front hood, and improving the user experience.

[0040] In one embodiment, continue to refer to Figure 4 and Figure 5 , the driving member 11 is rotatably connected to the front bumper assembly 2 to switch between the initial position and the unlocking position. When the driving member 11 is driven to the unlocking position, the driving member 11 drives the locking hook 32 to rotate in the unlocking direction. The initial position is the position where the driving member 11 is not affected by external force, and the unlocking position is the position where the driving member 11 is driven by external force to rotate. Of course, the driving member 11 can also be slidably connected to the front bumper assembly 2 to be able to drive the locking hook 32 to rotate in the Figure 5 unlocking direction as shown.

[0041] In a specific example, as Figure 4 shown, the driving member 11 includes a first section 11a and a second section 11b. The first section 11a is exposed outside the front bumper assembly 2, so as to facilitate user operation. As Figure 2 and Figure 4 shown, an installation hole is provided in the front bumper assembly 2, and the first section 11a is embedded in the installation hole. The outer shape of the first section 11a is similar to the outer shape of the front bumper assembly 2, so that the outer surface of the first section 11a and the front bumper assembly 2 can be smoothly transitioned.

[0042] Continue to refer to Figure 4 , the second section 11b is bent from the first section 11a to the inside of the front bumper assembly 2 and is in linkage cooperation with the first wire body 41. Specifically, a limiting groove 11b-1 that can be adapted to the limiting block 41a of the first wire body 41 is provided in the second section 11b, and the part where the limiting groove 11b-1 is located extends into the cavity surrounded by the support structure 22 of the front bumper assembly 2, so as to be in limiting cooperation with the limiting block 41a.

[0043] There is a connecting portion 11c between the first-stage portion 11a and the second-stage portion 11b. The connecting portion 11c has a set-like structure. The connecting portion 11c is pin-connected to a pin shaft 21 provided on the front bumper assembly 2. When the first-stage portion 11a is pushed into the front bumper assembly 2 along Figure 4 the pushing direction in

[0044] , the second-stage portion 11b rotates in the opposite direction to pull the first wire body 41 to move. Of course, the connecting portion 11c may not be provided between the first-stage portion 11a and the second-stage portion 11b, but may be provided on one side of the first-stage portion 11a away from the second-stage portion 11b or on one side of the second-stage portion 11b away from the first-stage portion 11a. At this time, the first wire body 41 can be driven to move by pulling the driving member 11 in the direction towards the outside of the vehicle, so as to drive the locking hook 32 to rotate in the unlocking direction. However, compared with the method in this embodiment, the method of arranging the connecting portion 11c between the first-stage portion 11a and the second-stage portion 11b is more labor-saving for the user to operate.

[0045] In addition, the method of driving and rotating the driving member 11 can be manual driving and rotating or electric driving and rotating. The manual driving and rotating method is the method that the user manually pushes the first-stage portion 11a into the front bumper assembly 2. The electric driving and rotating method is, for example, that a motor is fixedly provided on the front bumper assembly 2, and the motor is in transmission connection with the first-stage portion 11a. It can be in transmission connection through a gear assembly or a worm and worm gear transmission connection. An induction device is also provided on the first-stage portion 11a, which can sense the operation intention of the user's secondary unlocking. When it senses that the user needs to perform secondary unlocking, the motor starts to work to drive the first-stage portion 11a to rotate in the set direction.

[0046] Of course, the motor can also be directly connected to the second-stage portion 11b to be able to drive the locking hook 32 to rotate in the unlocking direction. It can be understood that, compared with the manual driving and rotating method, the electric driving and rotating method has a more complex structure and a more complex control system.

[0047] Optionally, as Figure 3 and Figure 4 shown, the unlocking mechanism 1 further includes a second return spring 12 sleeved outside the pin shaft 21. One end of the second return spring 12 is connected to the driving member 11, and the other end is connected to the front bumper assembly 2. When the first-stage portion 11a rotates along the pushing direction, the second return spring 12 is compressed circumferentially to be in a state of accumulating elastic potential energy. When the engine hood is opened, the driving member 11 returns to the initial working position under the action of the second return spring 12.

[0048] In some of the above examples, referring to Figure 6 and Figure 7 , the primary locking mechanism 3a includes a ratchet wheel 34 and a pawl 33 that are rotatably connected to the bottom plate 31, and the ratchet wheel 34 and the pawl 33 are in transmission cooperation.

[0049] The front cabin lock also includes a primary unlocking mechanism 1 adapted to the primary locking mechanism 3a. The primary unlocking mechanism 1 is a third wire drawing assembly 6, and the third wire drawing assembly 6 includes a third wire drawing body 61, one end of the third wire drawing body 61 extends into the cockpit, and the limit block 61b at the other end cooperates with the pawl 33. When the user performs the primary unlocking operation, the third wire drawing body 61 is pulled in the cockpit, thereby driving the pawl 33 to rotate, and the pawl 33 drives the ratchet 34 to rotate. When the ratchet 34 rotates, it can drive the lock tongue 32 to move for primary unlocking. The cooperation method of the ratchet 34 with the lock tongue for unlocking and unlocking is a prior art and will not be repeated here.

[0050] In some embodiments, see Figure 4 , Figure 5 and Figure 6 The unlocking mechanism 1 further includes a second transmission member, which is transmission-connected between the primary locking mechanism 3a and the first section 11a. Driven by the primary locking mechanism 3a, the first section 11a can rotate to the schematic position. The angle at which the first section 11a rotates to the schematic position is smaller than the angle at which the first section 11a rotates to the unlocking position. That is, in the pushing direction, the schematic position is located between the initial position and the unlocking position.

[0051] Specifically, the second transmission member includes a second wire drawing assembly 5. One end of the second wire drawing assembly 5 is used to form a linkage with the primary locking mechanism 3a of the front cabin lock of the vehicle, and the other end forms a linkage with the first section 11a. First, the primary locking mechanism 3a moves, and then the primary locking mechanism 3a can drive the first section 11a to rotate to the schematic working position.

[0052] like Figure 6 and Figure 7 As shown, the second wire drawing assembly 5 includes a second wire drawing body 51. The structure of the second wire drawing body 51 is the same as that of the first wire drawing body 41. The stopper 51b at one end of the second wire drawing body 51 forms a linkage with the ratchet 34. Figure 4 In the embodiment, the limiting block 51a at the other end of the second wire drawing body 51 forms a linkage fit with the first section 11a.

[0053] When performing primary unlocking, when the ratchet wheel 34 rotates under the action of the pawl 33, it can pull the second wire drawing body 51 to move, thereby driving the first section 11a to rotate along the pushing direction. Thus, when the user completes primary unlocking, the first section 11a can move relative to the front bumper assembly 2 to the indicated position, so as to indicate the position where the first section 11a is located to the user, thereby further facilitating the user to confirm the position where the first section 11a is located and improving the user experience. In addition, the primary locking mechanism 3a further includes a pawl spring 37 connected to the bottom plate 31 and the pawl 33 and a ratchet spring 38 connected to the bottom plate 31 and the ratchet wheel 34. The pawl spring 37 and the ratchet spring 38 are used to reset the pawl 33 and the ratchet wheel 34. Optionally, the primary locking mechanism 3a further includes a cover plate 39 connected to the bottom plate 31, and the pawl spring 37 and the ratchet spring 38 are located on the side of the cover plate 39 away from the pawl 33 and the ratchet wheel 34.

[0054] Meanwhile, the second section 11b will rotate in the reverse direction under the drive of the first section 11a. In order to prevent the second section 11b from being blocked by the first wire drawing body 41 when rotating in the reverse direction. When the limiting block 41a of the first wire drawing body 41 is in the initial position of the driving member 11, the limiting block 41a of the first wire drawing body 41 is arranged at an interval from the limiting groove 11b-1. And the distance between the limiting block 41a and the limiting groove 11b-1 is greater than the distance that the second section 11b moves when the first section 11a moves from the initial position to the indicated position.

[0055] Optionally, the stiffness of the second return spring 12 is less than the stiffness of the ratchet spring 38, so as to prevent the first section 11a from returning to the initial position under the action of the second return spring 12.

[0056] Optionally, referring to Figure 4 , a connecting groove 11d extends along the pushing direction on the first section 11a, and the connecting groove 11d extends along the inner side of the first section 11a towards the vehicle. The groove wall of the connecting groove 11d is arranged along the approximate height direction of the vehicle. A notch 11e is formed in the groove wall, and a part of the second wire drawing body 51 is embedded in the notch and can move axially in the notch 11e. The limiting block 51a of the second wire drawing body 51 is located in the connecting groove 11d and realizes linkage with the first section 11a through cooperation with the notch 11e. By providing the connecting groove 11d, the limiting block 51a of the second wire drawing body 51 can be hidden and prevented from being exposed outside the vehicle.

[0057] In an embodiment of the present invention, a front bumper assembly 2 is further provided, including the unlocking mechanism 1 described above.

[0058] In an embodiment of the present invention, a vehicle is further provided, including the front bumper assembly 2 described above.

[0059] In this article, specific examples are used to illustrate the principles and implementation modes of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present invention, several improvements and modifications can still be made to the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
