DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. In addition, the embodiments of the present invention and the features in the embodiments can be combined with each other if there is no conflict. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0025] Unless otherwise defined, technical or scientific terms used in this invention shall have the same ordinary meaning as those generally understood by persons of ordinary skill in the art to which this invention pertains. The terms "first," "second," and similar terms used in this invention do not denote any order, quantity, or importance, but are merely used to distinguish different components.

[0026] At present, pickup trucks on the market are not equipped with cargo box covers. When encountering heavy rain, heavy snow, hail and other weather conditions, the items stored in the cargo box are easily wetted and damaged. In addition, the open cargo box has poor anti-theft performance. In order to improve the anti-theft performance of the cargo box, an openable and closable box cover can be installed for the cargo box. In the prior art, in order to realize the openable and closable function of the box cover, a complete set of opening mechanisms needs to be installed inside the box cover. However, the existing opening mechanism needs to occupy a large installation space inside the box cover, and the actual internal space of the box cover is small, which makes it difficult to arrange the opening mechanism. In addition, the arrangement of the opening mechanism will also affect the flatness of the box cover surface. In view of this, the present invention provides a box cover unlocking device to solve the problem of small installation space and difficult arrangement of the box cover opening mechanism.

[0027] The specific implementation of the box cover unlocking device provided by the embodiment of the present invention is described in detail below with reference to the accompanying drawings.

[0028] like Figure 1 As shown, an embodiment of the present invention provides a box lid unlocking device, which includes fixing frames 01 and 02, an opening mechanism 03, a locking mechanism 04, and a clutch mechanism 05. It should be noted that the present invention divides the box lid unlocking device into the aforementioned multiple components according to the functional attributes of the components therein, and the components included in each mechanism are not fixed. In actual application, the division of different mechanisms and the composition of components can be flexibly set and adjusted according to actual needs, and this application does not impose any restrictions on this.

[0029] In the embodiment of the present invention, Figure 2 As shown, the fixing bracket 01 and the fixing bracket 02 can be installed on the vehicle cargo box cover 11, and the fixing bracket 01 and the fixing bracket 02 can be fixed to the box cover by bolts, welding, etc. Since the installation space of the box cover unlocking device is small, the fixing bracket 01 and the fixing bracket 02 can be set to a flat shape. The fixing bracket 01 and the fixing bracket 02 are used to install and fix other components in the box cover unlocking device. The shapes of other components can also be set to a flat shape to reduce the installation space required for the box cover unlocking device. This application does not impose specific restrictions on the number, size and installation method of the fixing brackets.

[0030] In the box cover unlocking device provided by the present invention, if Figure 1 As shown, the opening mechanism 03 is used to receive a driving force from the outside, for example, the driving force provided when the driver pulls the component 031 in the opening mechanism 03, and transmits the driving force from the opening mechanism 03 to the clutch mechanism 05, so that the clutch mechanism 05 is actuated. The way in which the opening mechanism 03 transmits the driving force can be direct contact transmission or indirect transmission, and this application does not make any specific restrictions on this.

[0031] In the box cover unlocking device provided by the present invention, if Figure 1 As shown, the clutch mechanism 05 is disposed on the fixing frame 02, and is used to cooperate with the opening mechanism 03 and the locking mechanism 04 to perform corresponding actions. For example, when the locking mechanism 04 drives the clutch mechanism 05 to operate in the unlocking state, the opening mechanism 03 can drive the clutch mechanism 05 to perform corresponding actions to unlock the trunk lid unlocking device; when the locking mechanism 04 drives the clutch mechanism 05 to operate in the locked state, even if the opening mechanism 03 transmits driving force to the clutch mechanism 05, the trunk lid unlocking device remains in the locked state.

[0032] In the embodiment of the present invention, specifically, Figure 1 and Figure 3 As shown, opening mechanism 03 includes a handle 031 and a first rotating member 032. One side of handle 031 is rotatably mounted on mounting bracket 01. To enable the driver to pull handle 031 to rotate, the other side of handle 031 extends to the lid surface and is parallel to the lid surface, ensuring the flatness of the lid surface. Handle 031 can be configured as an elongated strip and made of metal or plastic. This application does not impose any specific restrictions on this.

[0033] In the embodiment of the present invention, Figure 1 As shown, the first rotating member 032 is rotatably mounted on the fixed frame 02 and is rotatable about the first rotation axis 022. One end of the first rotating member 032 is in direct contact with one side of the handle 031. When the driver pulls the handle 031 to rotate, the side of the handle 031 pushes against the first rotating member 032 to rotate. The shape of the first rotating member 032 includes, but is not limited to, an "L" shape. In actual application, the shape of the first rotating member 032 can be adjusted according to actual application requirements. By configuring the first rotating member 032, it can directly transmit the driving force from the handle.

[0034] In the embodiment of the present invention, Figure 1 As shown, the locking mechanism 04 includes a lock core 041 for use with a key and a second rotating member 042 rotatably mounted on the fixed frame 02. The lock core 041 can be a copper cylindrical structure, and the internal structure of the lock core 041 can be composed of components such as a keyhole, a lock core baffle, a lock pin, and a lock plate, which are not specifically limited in this application.

[0035] The lock cylinder 041 is mounted on the fixed frame 01 and can rotate as the key inserted into the keyhole rotates. The second rotating member 042 can be connected to the fixed frame 02 via the second rotating shaft 021. The second rotating member 042 can rotate around the second rotating shaft 021 set on the fixed frame 02. One end of the second rotating member 042 is connected to the lock cylinder 041 through the connecting rod 043, and the other end is connected to the slider 051. When the key drives the lock cylinder 041 to rotate, the lock cylinder 041 can drive the second rotating member 042 to rotate around the second rotating shaft 021, causing the slider 051 to slide (as shown in FIG. Figure 1 By providing a lock core 041 and a second rotating member 042 that can rotate on the fixed frame 02, the position of the slider 051 can be switched to achieve the operational state of the switching clutch mechanism 05.

[0036] In the embodiment of the present invention, Figure 1 As shown, the clutch mechanism 05 includes a slider 051 rotatably and slidably mounted on the fixed frame 02. The slider 051 is connected to the fixed frame 02 via a first rotation axis 022. The slider 051 can rotate about the first rotation axis 022 and slide on the fixed frame 02. The clutch mechanism 05 also includes a third rotating member 052 slidably mounted on the fixed frame 02. The rotation axes of the third rotating member 052, the slider 051, and the first rotating member 032 coincide. That is, the third rotating member 052, the slider 051, and the first rotating member 032 can rotate about the first rotation axis 022. The first rotating member 032 and the third rotating member 052 each have at least one rotating arm. The first rotating member 032, the third rotating member 052, and the slider 051 can be configured as a flat shape to reduce the installation space required for the box cover unlocking device and facilitate installation of the clutch mechanism 05.

[0037] The slider 051 is used to connect or separate the first rotating member 032 and the third rotating member 052. When the lock core 041 drives the second rotating member 042 to rotate around the second rotating axis 021, so that the slider 051 slides to the first sliding position, the slider 051 can be combined with the first rotating member 032 and the third rotating member 052, so that the first rotating member 032 and the third rotating member 051 rotate synchronously; when the lock core 041 drives the second rotating member 042 to rotate around the second rotating axis 021, so that the slider 051 slides to the second sliding position, the slider 051 separates the first rotating member 032 and the third rotating member 052, and the first rotating member 032 and the third rotating member 051 rotate synchronously. The rotating member 052 can rotate separately; in an embodiment of the present invention, when the first rotating member 032 and the third rotating member 052 rotate synchronously, the first rotating member 032 can directly push the third rotating member 052 to rotate synchronously, and the first rotating member 032 and the third rotating member 052 can also be fixed by the slider 051 to indirectly push the third rotating member 052 to rotate. The present application does not impose specific restrictions on the functional relationship between the first rotating member 032 and the third rotating member 052. It should be pointed out that the third rotating member 052 is connected to a mechanism similar to a pull-wire lock, and when the third rotating member 052 rotates, the pull-wire lock can be unlocked.

[0038] In this way, the function of opening or closing the box lid can be realized, and the purpose of anti-theft can be achieved. In addition, the flat design method can reduce the installation space of the box lid unlocking device, making the box lid unlocking device easier to install on the box lid, thereby increasing the applicability of the box lid unlocking device.

[0039] In order to further explain how the box lid unlocking device provided in this application solves the problem of small installation space and difficult layout of the opening mechanism, and how to realize the opening and closing function of the box lid, a more detailed description is given below.

[0040] In an embodiment of the present invention, further, Figure 1 、 Figure 3 As shown, the opening mechanism 03 includes a handle 031 and a first rotating member 032. The handle 031 is rotatably arranged on the fixed frame 01, and the handle 031 has a lever 0311. In a specific implementation, in order to achieve synchronous rotation of the handle 031 and the lever 0311, the handle 031 and the lever 0311 can be connected by a fixed pin 033. The handle 031 and the lever 0311 can rotate around the fixed pin 033. The present application does not impose any specific restrictions on the connection method of the handle 031 and the lever 0311 and the shape of the fixed pin 033. In the embodiment of the present application, as shown in FIG. Figure 1 As shown, the first rotating member 032 is rotatably arranged on the fixed frame 02, and the first rotating member 032 has a baffle 0321, which is used to receive the driving force from the handle 031; the handle 031 rotates synchronously with the lever 0311, and the lever 0311 is used to drive the first rotating member 032 to rotate; illustratively, when the handle 031 and the lever 0311 rotate synchronously counterclockwise, since the first rotating member 032 has the baffle 0321, the lever 0311 will push the baffle 0321, causing the first rotating member 032 to rotate clockwise.

[0041] By arranging a lever 0311 that can rotate along with the handle 031 on the fixing frame 01 and arranging a baffle 0321 on the first rotating member 032 , the handle 031 can drive the first rotating member 032 to rotate.

[0042] In the embodiment of the present invention, Figure 1 As shown, the locking mechanism 04 includes a lock core 041 and a second rotating member 042. The lock core 041 is rotatably arranged on the fixed frame 01, and the second rotating member 042 is rotatably arranged on the fixed frame 02, and the lock core 041 is used to drive the second rotating member 042 to rotate. In a specific implementation, the locking mechanism 04 also includes a connecting rod 043, which can transmit the driving force from the lock core 041. One end of the connecting rod 043 is connected to the lock core 041, and the other end of the connecting rod 043 is connected to the second rotating member 042.

[0043] For example, Figure 1As shown, when the lock cylinder 041 rotates on the fixed frame 01 with the key inserted into the lock cylinder 041, since the lock cylinder 041 is connected to one end of the connecting rod 043 and the connecting rod 043 is not easily deformed, and since the second rotating member 042 is rotatably mounted on the fixed frame 02 and one end of the rotating arm of the second rotating member 042 is connected to one end of the connecting rod 043, the connecting rod 043 drives the second rotating member 042 to rotate about the second rotating axis 021 on the fixed frame 02. It should be noted that the connecting rod can be made of metal, alloy, or other material that is not easily deformed. This application does not impose any specific restrictions on the material of the connecting rod and will not be further described here.

[0044] By providing a lock core 041 rotatable on the fixed frame 01 , a connecting rod 043 connected to the lock core 041 , and a second rotating member 042 connected to the connecting rod 043 , the position of the slider 051 can be switched, thereby achieving switching of the operational state of the clutch mechanism 05 .

[0045] In the embodiment of the present invention, Figure 1 As shown, the clutch mechanism 05 includes a slider 051 rotatably and slidably disposed on the fixed frame 02 and a third rotating member 052 rotatably disposed on the fixed frame 02. The first rotating member 032, the slider 051, and the third rotating member 052 are connected by a first rotating shaft 022, and the first rotating member 032, the slider 051, and the third rotating member 052 are rotatable about the first rotating shaft 022. The second rotating member 042 is connected to the slider 051 and is used to slide the slider 051 to a first sliding position or a second sliding position.

[0046] In order to more clearly describe the motion relationship between the second rotating member 042 and the slider 051, the following is a Figure 1 , Attachment Figure 4 And attached Figure 5 Describe in detail.

[0047] In the embodiment of the present invention, Figure 4 As shown, the slider 051 has a fixing pin 0511 and a positioning hole 0512. The first rotating shaft 022 is fixed to the fixing frame 02, and cooperates with the fixing frame 02 to realize the rotation and limiting of the first rotating member 032, the third rotating member 052 and the slider 051 on the fixing frame 02. The first rotating shaft 022 is passed through the positioning hole 0512, so that the slider 051 can rotate around the first rotating shaft 022, and the positioning hole 0512 is long and narrow, which can enable the fixing pin 0511 to slide along the length direction of the positioning hole 0512.

[0048] In the embodiments of this application, Figure 5As shown, the second rotating member 042 has a limiting hole 0421, which can be set to an arc, an ellipse or any other shape; the fixing pin 0511 is inserted into the limiting hole 0421 and abuts against the inner wall of the limiting hole 0421, combined with Figure 1 As shown, for example, when the connecting rod 043 drives the second rotating member 042 to rotate around the second rotating axis 021 on the fixing frame 02, the inner wall of the limiting hole 0421 will push the fixing pin 0511 to slide.

[0049] Regarding the sliding track of the fixed pin 0511, the following Figure 6 , and attached Figure 7 Provide a detailed description.

[0050] In the embodiment of the present invention, Figure 6 As shown, the first rotating member 032 has a first slide 0322, and the first slide 0322 can be set to an "L" shape or any other shape. The first slide 0322 is used to drive the fixing pin 0511 to engage or separate the third rotating member 052 to slide; the first slide 0322 has a sliding section 03221 and a limiting section 03222, and the fixing pin 0511 can be slidably arranged in the first slide 0322.

[0051] In the embodiment of the present invention, Figure 7 As shown, the third rotating member 052 has a third slide 0521. The third slide 0521 can be set to a roughly "one" shape or any other arbitrary shape. The third slide 0521 is used to abut against the fixed pin 0511 and rotate synchronously with the fixed pin 0511; illustratively, the fixed pin 0511 is passed through the third slide 0521 and abuts against the inner wall of the third slide 0521.

[0052] Since the fixing pin 0511 is simultaneously provided in the first slide 0322, the limiting hole 0421 and the third slide 0521, the moving trajectory of the fixing pin 0511 should be the area with the smallest area between the first slide 0322 and the third slide 0521. Therefore, when the connecting rod 043 drives the second rotating member 042 to rotate around the second rotation axis 021 on the fixed frame 02, the inner wall of the limiting hole 0421 will push the fixing pin 0511 to slide in the limiting section 03222. The length direction of the limiting section 03222 is parallel to the sliding direction of the slider 051, and the length direction of the third slide 0521 is parallel to the sliding direction of the slider 051.

[0053] Here, it should be pointed out that Figure 6In the figure, it is assumed that the initial position of the slider 051 is the first sliding position (not marked), and the initial position corresponding to the fixing pin 0511 on the slider 051 is the third sliding position 032221; when the second rotating member 042 rotates counterclockwise around the second rotating axis 021, the slider 051 slides to the second sliding position. At this time, the fixing pin 0511 on the slider 051 corresponds to the fourth sliding position 032222.

[0054] In an embodiment of the present invention, when the slider 051 is located in the first sliding position, the fixing pin 0511 is located in the limiting section 03222, and the fixing pin 0511 is against the inner wall of the limiting section 03222; when the slider 051 is located in the second sliding position, the fixing pin 0511 is located in the sliding section 03221 and can slide in the sliding section 03221.

[0055] After determining the sliding trajectory of the fixed pin 0511, the rotation trajectory of the fixed pin 0511, the motion relationship between the fixed pin 0511 and the first sliding member 032, and the motion relationship between the fixed pin 0511 and the third sliding member 052 are described below in conjunction with the attached Figure 1 、 4 , 5, 6, give a detailed description.

[0056] In the embodiment of the present invention, when the slider 051 is located at the first sliding position, the slider 051 can rotate synchronously with the first rotating member 032 and the third rotating member 052. Figure 6 As shown, when the slider 051 is located at the first sliding position, the fixing pin 0511 is located at the third sliding position 032221 within the limiting section 03222, and the inner wall of the limiting section 03222 abuts against the fixing pin 0511. Therefore, when the handle 031 drives the first rotating member 032 to rotate clockwise around the first rotating axis 022, the inner wall of the limiting section 03222 pushes the fixing pin 0511 to rotate clockwise synchronously with the first rotating member 032; Figure 7 As shown, the fixing pin 0511 is inserted into the third slideway 0521 of the third rotating member 052 and abuts against the inner wall of the third slideway 0521. When the fixing pin 0511 rotates clockwise synchronously with the first rotating member 032, the fixing pin 0511 will push the third rotating member 052 to rotate clockwise synchronously around the first rotation axis 022.

[0057] In the embodiment of the present invention, when the slider 051 is located at the first sliding position, and the fixing pin 0511, the first rotating member 032 and the third rotating member 052 rotate synchronously clockwise around the first rotating shaft 022, the combination Figure 5As shown, the second rotating member 042 has a limiting hole 0421, which has a second slideway 04211. The rotation trajectory of the fixing pin 0511 is located within the second slideway 04211. Considering that the sliding of the fixing pin 0511 within the second slideway 04211 may affect the second rotating member 042, such as some minor vibrations, a fourth slideway 0422 is provided at the connection between the second rotating member 042 and the connecting rod 043. The fourth slideway 0422 can provide sliding space for the connecting rod 043 when the handle 031 drives the fixing pin 0511 to rotate, thereby increasing the degree of freedom of the connecting rod 043 and preventing damage to the lock cylinder 041.

[0058] In the embodiment of the present invention, when the slider 051 is located at the second sliding position, the slider 051 separates the first rotating member 032 and the third rotating member 052, and the first rotating member 032 and the third rotating member 052 can rotate separately. Figure 6 As shown, when the slider 051 is located at the second sliding position, the fixing pin 0511 is located at the fourth sliding position 032222 in the limiting section 03222. At this time, when the handle 031 drives the first rotating member 032 to rotate clockwise around the first rotating axis 022, since the fixing pin 0511 is located on the rotation trajectory of the first rotating member 032 around the first rotating axis 022, that is, the inner wall of the limiting section 03222 fails to resist the fixing pin 0511, the fixing pin 0511 does not move, and the fixing pin 0511 is located in the sliding section.

[0059] From the above, it can be seen that in the box cover unlocking device provided by the present application, the lock core 041, the connecting rod 043 and the second rotating member 042 constitute an anti-theft locking structure. When the key is inserted into the lock core 041 and rotated counterclockwise on the fixing frame 01 by a certain angle, for example 55°, the lock core 043 drives the connecting rod 043 to move to the side away from the third rotating member 052. At the same time, the connecting rod 043 drives the second rotating member 042 to rotate counterclockwise, causing the fixing pin 0511 to slide to the fourth sliding position 032222 located in the limiting section 03222, thereby locking the locking structure. At this time, even if the handle 031 drives the first rotating member 032 to rotate clockwise around the first rotating axis 022, since the fixing pin 0511 is located on the rotation trajectory of the first rotating member 032 around the first rotating axis 022, that is, the inner wall of the limiting section 03222 fails to resist the fixing pin 0511, the fixing pin 0511 will not be displaced.

[0060] When the key is inserted into the lock cylinder 041 and rotated clockwise on the fixing frame 01 by a certain angle, for example 55 degrees, the lock cylinder 043 drives the connecting rod 043 to move toward the side close to the third rotating member 052. At the same time, the connecting rod 043 drives the second rotating member 042 to rotate clockwise, causing the fixing pin 0511 to slide to the third sliding position 032221 located in the limiting section 03222, thereby unlocking the locking structure; at this time, the handle 031 drives the first rotating member 032 to rotate clockwise around the first rotating axis 022. Because the fixing pin 0511 is simultaneously provided in the limiting section 03222 of the first rotating member 032 and the third slideway 0521 of the third rotating member 052, and abuts against the inner walls of the limiting section 03222 and the third slideway 0521, the fixing pin 0511 will push the third rotating member 052 to rotate synchronously clockwise around the first rotating axis 022, thereby realizing the opening and closing function of the box cover.

[0061] In the embodiment of the present invention, when the handle 031 no longer drives the first rotating member 032 to rotate clockwise around the first rotating axis 022, the third rotating member 052 can return to its initial position (reset position). Figure 7 As shown, the third slideway 0521 of the third rotating member 052 is in a horizontal state; Figure 1 As shown, a return spring 053 is also provided in the clutch mechanism 05, one end of the return spring 053 is connected to the fixed frame 02, and the other end is connected to the third rotating member 052. Figure 4 and Figure 7 As shown, the return spring 053 can be a torsion spring, the center of which is sleeved on the first rotating shaft 022. One end of the torsion spring is fixed to the rotating arm of the third rotating member 052, and the other end is fixed to the fixed frame 02. In order to facilitate the connection between the torsion spring and the third rotating member 052, first grooves 05321 can be provided on the rotating arms at both ends of the third rotating member 052. When the first rotating member 032 drives the third rotating member 052 to rotate, the return spring 053 is tightened and stress is generated. When the driving force of the first rotating member 032 is released, the elastic force of the return spring can rotate the third rotating member 052 to the reset position. This application does not impose any specific restrictions on the type and material of the spring, and no further details are given here.

[0062] Based on the same invention concept, Figure 8 As shown, the present invention also provides a vehicle, including a box body 10 and a box cover 11, the box body 10 and the box cover 11 are arranged at the rear of the vehicle, the box cover 11 is detachably mounted on the top surface of the box body 10, and the box cover 11 includes the above-mentioned box cover unlocking device, which is applicable to boxes equipped with various types of vehicles, such as Figure 9As shown, the box cover unlocking device also includes a lock tongue mechanism 06 and a pull wire mechanism 07; the lock tongue mechanism 06 includes a lock tongue 061 and a lock buckle 062 that can lock with each other, the lock tongue 061 is rotatably arranged on the box cover 11, and a return spring 0612 is arranged on the third rotation axis 0611 of the lock tongue 061. When the pull wire mechanism 07 drives the lock tongue 061 to rotate around the third rotation axis 0611 to a certain angle, the lock tongue 061 and the lock buckle 062 are unlocked. Figure 9 , the lock tongue 061 and the lock buckle 062 are in the initial locked state; when the wire pulling mechanism stops applying driving force to the lock tongue 061, the lock tongue 061 is reset to the initial locked state by the return spring 0612.

[0063] The lock 062 is fixed to the box 10, combined with Figure 1 As shown, the wire pulling mechanism 07 includes a wire pulling mechanism 073 and a sleeve 074. The wire pulling mechanism 073 is arranged in the sleeve 074 and can slide freely in the sleeve 074. The lengths of the wire pulling mechanism 073 and the sleeve 074 are fixed. One end of the wire pulling mechanism 073 is arranged on the rotating arm of the third rotating member 052 away from the first rotating shaft 022, that is, at the position of the first terminal 072. The other end of the wire pulling mechanism 073 is connected to the locking tongue 061, that is, at the position of the second terminal 071. One end of the sleeve 074 is arranged on the fixing frame 02, and the other end is arranged on the box cover 11. When the third rotating member 052 rotates along the first rotating shaft 022, the locking tongue 061 is connected to the locking tongue 061. When the clockwise rotation is performed, the third rotating member 052 will drive the pull wire 073 to rotate clockwise, so that the pull wire 073 sleeved in the sleeve 074 moves in the direction away from the sleeve 074; since the length of the pull wire 073 is fixed, the other end of the pull wire 073 will push the lock tongue 061 to rotate around the third rotation axis 0611. When the lock tongue 061 rotates to a certain angle around the third rotation axis 0611, for example, 50°, the lock tongue 061 and the lock buckle 062 are unlocked. This application does not impose any specific restrictions on the angle at which the lock 061 rotates around the third rotation axis 0611 when the lock is unlocked, and will not be repeated here.

[0064] By arranging a pull wire mechanism 07 and a lock tongue mechanism 06 on the box lid and a lock buckle 062 on the box body 10, after the locking mechanism 04 is unlocked, the third rotating member 052 can be driven by the handle 031 to rotate around the first rotating axis 022 to achieve unlocking between the box lid 11 and the box body 10; when the locking structure 04 is not unlocked, the handle 031 will not drive the third rotating member 052 to rotate around the first rotating axis 022, and the box lid 11 and the box body 10 cannot be unlocked. In this way, the anti-theft performance of items stored in the box body can be improved.

[0065] Furthermore, since the internal space of the actual box cover 11 is small, and in order to facilitate the arrangement of the box cover unlocking device in the box cover 11, the box cover unlocking device provided by the present invention occupies very little space in the thickness direction. Figure 1 As shown, the rotation axes of handle 031, first rotating member 032, second rotating member 042, slider 051, and third rotating member 052 are all arranged parallel to each other, and the sliding direction of slider 051 is perpendicular to the rotation axis of slider 051, i.e., the first rotation axis. This approach can reduce the space occupied by the box lid unlocking device and improve the flatness and aesthetics of the box lid.

[0066] The present application does not impose any specific restrictions on the stacking method between the handle 031, the first rotating member 032, the second rotating member 042, the slider 051 and the third rotating member 052. It can be achieved that when the slider 051 is in the first sliding position, the first rotating member 032 can drive the third rotating member 052 to rotate synchronously; when the slider is in the second sliding position, the first rotating member 032 is separated from the third rotating member 052, and the third rotating member 052 does not rotate synchronously with the first rotating member 032. For example, the slider 052 can be set on the top layer, followed by the second rotating member 042, then the third rotating member 052, and then the first rotating member 032, and the fixed member 02 is set at the bottom layer. Here, the stacking order of the rotating members and the slider 052 is not repeated.

[0067] Considering the anti-theft property of the vehicle, in the box cover unlocking device provided by the present invention, as Figure 8 As shown, the box cover 11 also has a cover plate 111, and the sliding direction of the slider 051 is parallel to the plate surface of the cover plate 111. The box cover unlocking device adopts a flattened design method, which can expand the application range of the box cover unlocking device and overcome the problem of small installation space and difficult layout of the box cover opening mechanism.

[0068] In summary, the trunk lid unlocking device provided by the present invention is applicable to various types of vehicles. When unlocking the trunk lid, it is first necessary to use the lock cylinder, connecting rod, and second rotating member to drive the slider to the first sliding position to unlock the locking structure; then, the handle is pulled, and the handle drives the first rotating member, the slider, and the third rotating member to rotate synchronously, so that the pull wire moves a certain distance in the direction away from the sleeve, thereby unlocking the trunk lid and the box body. In consideration of the problem of the narrow installation space of the trunk lid, the trunk lid unlocking device provided by this application adopts a flattened design method, and each rotating member moves horizontally, which solves the problem of the narrow installation space and difficult layout of the trunk lid unlocking device, and improves the flatness and aesthetics of the trunk lid and the applicability of the trunk lid unlocking device.

[0069] Obviously, those skilled in the art may make various changes and modifications to this application without departing from the spirit and scope of this application. Thus, if these modifications and variations of this application fall within the scope of the claims of this application and their equivalents, this application is intended to include these modifications and variations.
