Description

Technical Field

[0001] This utility model relates to the field of rooftop tent technology, and in particular to a locking structure for use in rooftop tents. Background Technology

[0002] With economic development and the widespread use of automobiles, more and more people are choosing to travel by car during holidays, leading to the emergence of rooftop tents. Rooftop tents that connect to the car roof are considered high-end products and are very popular in the market. However, considering the stability of rooftop tents when mounted on a moving vehicle, their locking structures are often quite complex, resulting in slow installation. Furthermore, the locking mechanisms of existing rooftop tents are often exposed to the elements, directly affecting their lifespan. Utility Model Content

[0003] The technical problem this invention aims to solve is that the lock structure of rooftop tents is complex and mostly exposed outside the tent, resulting in a short service life.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0005] A locking structure for a rooftop tent includes an upper locking structure and a lower locking structure. The upper locking structure is installed inside the upper cover cavity of the rooftop tent, and the lower locking structure is installed inside the lower cover cavity of the rooftop tent. The upper locking structure and the lower locking structure are correspondingly arranged, and the upper cover and the lower cover are locked together by the locking structure.

[0006] The locking structure includes a housing, a latch, pins, and a control handle. The housing is open at one end and hollow inside. Positioning grooves are correspondingly formed on both sides of the middle portion of the housing. The latch is located inside the housing, and grooves are formed on both sides of the middle portion of the latch. Through holes are formed within these grooves. Two identical pins are provided, each positioned in one of the grooves on either side of the latch. When the latch is in the latched-on state, the pins are engaged in the positioning grooves. Pin springs are installed within the through holes, and the two pins abut against the ends of the pin springs. A reset hole is formed at the tail of the latch, and a reset spring is installed within the reset hole. The tail of the reset spring abuts against the inner wall of the housing.

[0007] The control handle includes a lever and a paddle. The paddle is U-shaped. The lever and the paddle are fixedly connected. The paddle is disposed between the latch and the outer shell, and its two ends are respectively disposed opposite to two pins. The lever controls the paddle to drive the latch to move back and forth.

[0008] Preferably, the upper locking structure is a rod-shaped structure and is installed in the upper cover cavity. Its installation position is the limiting position of the lower locking structure, and the locking tongue and the rod-shaped structure are fastened together.

[0009] Preferably, one end of the pin is a trapezoidal portion and the other end is a cylindrical portion, and the cylindrical portion is provided with a spring mounting hole, and the pin spring is installed in the spring mounting hole.

[0010] Preferably, the trapezoidal portion of the pin is a right-angled trapezoid, and the inclined surface of the trapezoidal portion is opposite to the positioning groove, and the length of the inclined surface of the trapezoidal portion is greater than the length of the positioning groove. When the lock tongue is locked, the inclined surface of the trapezoidal portion is engaged in the positioning groove for limiting.

[0011] Preferably, the control handle includes a lever and a paddle, the inner surface of the paddle being an inclined surface, and the inclined surface contacting the inclined surface of the trapezoidal portion.

[0012] When the user moves the lever backward to unlock, the bolt moves backward inside the housing as the lever moves backward. When it moves to a certain position, the pin installed on the bolt moves outward under the action of the pin spring, aligning with the positioning hole groove on the housing and locking into the edge of the positioning groove, thereby fixing the bolt. At this time, the external structure of the bolt is disengaged from the fixing rod installed on the roof tent cover.

[0013] When the user moves the lever forward and locks, the inclined surface of the lower part of the lever contacts the inclined surface of the pin and pushes the pin to move inward. The trapezoidal part of the pin disengages from the edge of the positioning hole in the outer shell, and the lock tongue moves forward under the action of the return spring, thus completing the locking.

[0014] When the user places the lever in the front position, the latch moves backward, the outer casing positioning groove is blocked by the lever, the latch is in the automatic state, and the user presses the roof tent cover onto the lower box to complete the automatic locking.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] (1) The present invention provides a lock structure for a rooftop tent, including an upper lock structure and a lower lock structure. The upper cover and the lower cover are locked by the lock structure. The lower lock structure includes a shell, a latch, a pin and a control handle. One end of the shell is open and the interior is hollow. The latch moves and self-locks inside the shell through the control handle, thereby completing the locking and opening actions of the upper cover and the lower cover. The structure is ingenious and easy to operate. The lock structure is set inside the cavity of the upper cover and the lower cover of the rooftop tent, which is both beautiful and improves the service life of the lock structure.

[0024] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0025] This utility model discloses a lock structure for use in rooftop tents, such as... Figure 1 and 2 As shown, the lock structure includes an upper locking structure 3 and a lower locking structure 4. The upper locking structure 3 is installed inside the upper cover cavity 1 of the roof tent, and the lower locking structure 4 is installed inside the lower cover cavity 2 of the roof tent. The upper locking structure 3 and the lower locking structure 4 are arranged correspondingly. Preferably, the upper locking structure 3 is a rod-shaped structure and is installed inside the upper cover cavity 1. Its installation position is the limiting position of the lower locking structure 3. When the roof tent is closed, the lower locking structure 4 and the upper locking structure 3 are interlocked.

[0026] like Figure 2 and 3 As shown, the lower locking structure 3 includes a housing 41, a latch 42, pins, and a control handle. The housing 41 is open at one end and hollow inside. Positioning grooves 44 are correspondingly formed on both sides of the middle portion of the housing 41; these positioning grooves 44 are door-shaped. The latch 42 is located inside the housing 41. Grooves 45 are formed on both sides of the middle portion of the latch 42, and through holes 46 are provided within these grooves 45. Two pins with identical structures are provided, and the two pins are correspondingly positioned within the grooves 45 on both sides of the latch 42. Figure 4 As shown, when the latch 42 is in the hanging state, the pin is engaged in the positioning groove 44, and a pin spring is provided in the through hole 46. The two pins abut against the two ends of the pin spring respectively. A reset hole 43 is provided at the tail of the latch 42, and a reset spring is provided in the reset hole 43. The tail of the reset spring abuts against the inner wall of the outer shell 41.

[0027] like Figure 4 As shown, the control handle includes a lever 48 and a paddle 49. The paddle 49 is U-shaped. The lever 48 and the paddle 49 are fixedly connected. The paddle 49 is located between the latch 42 and the outer casing 41, and both ends of the paddle 49 are respectively positioned opposite to two pins.

[0028] Preferably, one end of the pin is a trapezoidal portion 50, and the other end is a cylindrical portion 51, with the cylindrical portion 51 having a spring mounting hole 47, into which the pin spring is installed. The trapezoidal portion 50 of the pin is a right-angled trapezoid, and the inclined surface of the trapezoidal portion 50 is opposite to the positioning groove 44. The control handle includes a lever 48 and a paddle 49. The inner surface of the paddle 49 is an inclined surface, which contacts the inclined surface of the trapezoidal portion 50. Under force, the inclined surface of the paddle 49 moves along the inclined surface of the trapezoidal portion 50 and compresses the trapezoidal portion 50, causing the pin spring to deform and the pin to move away from the positioning groove 44.

[0029] like Figures 1 to 4 As shown, the method of using a lock structure applied to a rooftop tent is as follows:

[0030] The rooftop tent's upper and lower covers are locked, with the upper locking mechanism 3 and the lower locking mechanism 4 interlocked. The latch 42 in the lower locking mechanism 4 protrudes and engages with the upper locking mechanism 3.

[0031] When the rooftop tent needs to be opened, the operator holds the lever 48 of the control handle and applies force to the tail of the housing 41. The lever 49 slides backward away from the pin, which drives the locking tongue 42 to move backward and squeeze the return spring. The trapezoidal part 50 of the pin is positioned in the positioning groove 44. The locking tongue 42 is fixed inside the housing 41, and the rooftop tent can be opened.

[0032] When the rooftop tent cover needs to be locked, the operator holds the control handle and moves it forward. The lever 49 moves forward along the inclined plane of the trapezoidal part 50 and squeezes the pins on both sides. The return spring pushes the locking tongue 42 out of the outer shell 41, and the locking tongue 42 engages with the locking structure 3, thus completing the locking of the upper and lower covers.

[0033] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
