[0042] The lock body of the rolling shutter cover has the following problems: (1) The lock body is provided with a push-type switch, which has a large resistance and requires a great deal of effort to open. (2) The lock body adopts a rotary linkage switch, but the internal structure of the lock body is complex, the cost is high, and it is easy to be damaged.

[0043] In order to solve at least one of the above technical problems, the present application provides a lock body 300 and a rolling shutter cover 10 including the lock body 300.

[0044] With reference to Figure 1 and Figure 2 , the rolling shutter cover 10 is used to cover the tailgate of a pickup truck. The rolling shutter cover 10 has an open state as shown in Figure 1 and a storage state as shown in Figure 2 . When the rolling shutter cover 10 is in the open state, the rolling shutter cover 10 can prevent the goods or sports equipment in the pickup truck tailgate from being blown by the wind and rained on. When the rolling shutter cover 10 is in the storage state, the user can carry goods in the pickup truck tailgate. It can be understood that in addition to being able to cover the rear compartment of a pickup truck, the rolling shutter cover 10 can also be used to cover the cargo compartments of vehicles such as cars and heavy-duty trucks.

[0045] Refer to Figure 3, the rolling shutter cover 10 includes a rolling shutter 100, a slide rail 200, and a lock body 300. The rolling shutter 100 is connected to the slide rail 200. The rolling shutter 100 includes a plurality of curtain leaves 110 connected in sequence. The rolling shutter 100 can move along the slide rail 200 to switch the rolling shutter cover 10 between an open state and a stored state. The lock body 300 can abut against or cancel abutting against the slide rail 200 to fix or unfix the rolling shutter 100 on the slide rail 200.

[0046] Specifically, referring to Figure 4 , Figure 5 and Figure 6 , the lock body 300 includes a housing 310, a lock tongue 320, a driving assembly 330, a control assembly 340, and an electric control assembly 350. The lock tongue 320 is connected to the housing 310. The driving assembly 330 is disposed in the housing 310. The driving assembly 330 is connected to the lock tongue 320. The driving assembly 330 is configured to drive the lock tongue 320 to abut against or cancel abutting against the slide rail 200 relative to the housing 310, so as to achieve the effect of fixing or unlocking the rolling shutter 100. Of course, the lock tongue 320 can also abut against the carriage of the vehicle. The control assembly 340 is connected to the driving assembly 330. The control assembly 340 is provided with an operation portion 341 for a human hand to hold. The electric control assembly 350 includes a key 351 and a driving device. The driving device is connected to the driving assembly 330 or the control assembly 340. The driving device is configured to drive the driving member 331 or the control member 342 to rotate.

[0047] Specifically, the driving device can be a power source such as a driving motor or a driving cylinder.

[0048] In the present utility model, due to the provision of the control assembly 340 having the operation portion 341 and the electric control assembly 350 having the key 351, the lock body 300 has a manual mode of manually pushing the operation portion 341 and an electric mode of pressing the key 351, making the opening and closing of the lock body 300 more convenient. At the same time, having two modes can meet the different needs of users and has a higher error tolerance rate.

[0049] Figure 6It is illustrated that the driving assembly 330 includes a driving member 331 and a driving shaft 332. The two axial ends of the driving shaft 332 respectively penetrate through the housing 310 and the driving member 331, such that the driving member 331 can rotate relative to the housing 310 around the driving shaft 332. The control assembly 340 includes a control member 342 and a control shaft 343. The two axial ends of the control shaft 343 respectively penetrate through the housing 310 and the driving member 331, such that the control member 342 can rotate relative to the housing 310 around the control shaft 343. The operation part 341 is arranged on the control member 342, and the control member 342 is connected to the driving member 331. In this way, the rotation of the control member 342 drives the rotation of the driving member 331, so that the driving member 331 drives the locking tongue 320 to move. The transmission of the lock body 300 is simple and has small resistance, and it is more labor-saving for users to manually operate.

[0050] It can be understood that in some embodiments, the lock body 300 can achieve the reset of the control member 342 by arranging a torsion spring on the control shaft 343. Specifically, when the control member 342 is rotated, the torsion spring is compressed, and the control member 342 drives the driving member 331 to rotate. When the external force acting on the control member 342 is cancelled, the torsion spring releases the elastic force to drive the control member 342 to return to its original position. Of course, the torsion spring can also be controlled by a return spring or the like.

[0051] Specifically, referring to Figure 5 and Figure 6 , the control member 342 is provided with a first tooth part 3421, and the driving member 331 is provided with a second tooth part 3311 adapted to the first tooth part 3421. Under the action of an external force, the control member 342 rotates to drive the driving part to rotate, and the driving part drives the locking tongue 320 to move relative to the housing 310. In this way, no additional transmission structure needs to be added between the control member 342 and the driving member 331, the transmission is simple, and the transmission is more stable through the tooth part transmission. Of course, the manufacturer can also set other transmission structures between the control member 342 and the driving member 331 according to needs, such as a cam-link structure.

[0052] Referring to Figure 6 and Figure 7 , a limiting track 311 is arranged on the housing 310, and the driving member 331 is provided with a protrusion 3312. At least part of the protrusion 3312 is embedded in the limiting track 311. In this way, when the driving member 331 rotates to a preset angle, the protrusion 3312 will abut against the inner wall of the limiting track 311 and be limited, so as to prevent the driving member 331 from continuing to rotate and hitting the housing 310 or getting stuck. It can be understood that the preset angle here is determined by the limiting track 311. The present invention does not limit the shape and length of the limiting track 311, and the manufacturer can freely set it according to needs.

[0053] Specifically, the limiting track 311 is an arc track 312. Setting the limiting track 311 as an arc is adapted to the rotation of the driving member 331, making the rotation of the driving member 331 smoother.

[0054] In this embodiment, referring to Figure 7 , the lock body 300 is arranged inside the rolling curtain 100 and part of the housing 310 is exposed on the lower surface of the rolling curtain 100, reducing the risk of the button 351 and the operating part 341 being accidentally triggered. Among them, at least part of the button 351 is exposed from the housing 310 for manual pressing, and the operating part 341 is exposed from the housing 310. In this way, the user can conveniently use the electric mode or the manual mode of the lock body 300. The operating part 341 is also provided with a groove 3411 matching the finger to further enhance the experience of manually holding the operating part 341.

[0055] Specifically, the lock body 300 further includes a transmission rope 360. The opposite ends of the transmission rope 360 are respectively connected to the driving member 331 and the lock tongue 320. Since there is generally a certain distance between the lock body 300 and the slide rail 200, the driving member 331 can better drive the lock tongue 320 through the transmission of the transmission rope 360.

[0056] In this embodiment, the transmission rope 360 is a steel wire rope 361. The steel wire rope 361 has high strength, can withstand large loads, and the surface hardness of the steel wire rope 361 is relatively high, and the wear resistance is also good. It is not easy to be damaged even after long-term use. It can be understood that in other embodiments, the manufacturer can also replace the steel wire rope 361 with a nylon rope, a hemp rope, a leather rope, etc. The service life of these ropes will be lower than that of the steel wire rope 361, but they still have a similar transmission effect.

[0057] Furthermore, the number of the slide rails 200, the number of the transmission ropes 360, and the number of the lock tongues 320 are all two. The two lock tongues 320 are respectively located on the opposite sides of the housing 310. The transmission ropes 360 are respectively located on the opposite sides of the housing 310 and are respectively connected to the corresponding lock tongues 320. In this way, when the rolling curtain 100 is locked, the two lock tongues 320 respectively abut against the slide rails 200 on both sides of the rolling curtain 100, making the forces on both sides of the rolling curtain 100 uniform, and the rolling curtain 100 will not be deformed or bent due to unilateral force.

[0058] In summary, the lock body 300 in the present utility model not only has an electric mode and a manual mode for the user to choose, is convenient to operate and has a high error tolerance rate, but also drives the driving member 331 to rotate through the rotation of the control member 342, thereby driving the lock tongue 320. The structure is simple, the transmission is stable, the overall cost of the lock body 300 is lower, and the service life is longer.

[0059] The specific embodiments described herein are merely illustrative of the spirit of the present utility model. Those skilled in the art to which the present utility model pertains can make various modifications or supplements to the described specific embodiments or use similar means for substitution, but will not deviate from the scope defined by the spirit of the present utility model.
