Description

Technical Field

[0001] The utility model relates to the technical field of wrenches, in particular to a multifunctional anti-theft wrench for automobile awnings. Background Art

[0002] With the development of society and the advancement of science and technology, cars have become popular in thousands of households and have become one of the main means of transportation for people's daily travel. While providing convenience for people's travel, due to the concentration of urbanized population, the parking spaces in the city are difficult to meet the demand, which also brings about the problem of difficulty in parking. In particular, the number of underground garages is limited, resulting in a large number of vehicles having to be parked outdoors.

[0003] Due to the strong sunlight in summer, the temperature inside the car will be too high when the car is parked outdoors and exposed to the sun. On the one hand, it will reduce the comfort of the driver and passengers after entering the car. On the other hand, the increase in the temperature inside the car will accelerate the aging of leather goods, plastic products, circuits, etc. in the car. In addition, under high temperature, seat plastics and other car decorations may release harmful gases to the human body, causing harm to the health of the driver and passengers.

[0004] In order to solve this technical problem, a variety of car awnings have appeared on the market. However, the common problems of these car awnings are: (1) the awnings need to be opened and closed manually, which is inconvenient; (2) the awning disassembly and assembly process is cumbersome; (3) the awning disassembly and assembly process may cause scratches on the vehicle.

[0005] In order to solve the problem that the disassembly and assembly process of the awning is cumbersome and the process of disassembling and assembling the awning may cause scratches to the vehicle, the utility model patent with the authorization announcement number CN206953966U discloses a vehicle-mounted fully automatic awning, which fixes the awning to the roof by vacuuming the suction cup, so as to achieve the purpose of no need to punch holes in the roof, no damage to the vehicle during installation and removal, and no trace installation. However, during the driving process of the vehicle, the bumps of the vehicle can easily cause the vacuum environment of the suction cup to be destroyed, causing the suction cup to detach from the roof. In addition, since the awning is installed on the roof, it is exposed outside the vehicle and there is a certain risk of theft.

[0006] To this end, the applicant proposed a car awning clamp and a car awning (authorization announcement number: CN220314691U) on August 4, 2023. The car awning clamp can overcome the disadvantages of the vacuum suction cup on the one hand, and on the other hand, can realize encryption processing of the car awning to prevent the car awning exposed outside the car from being stolen.

[0007] After further research, practice and customer feedback, the inventor found that this anti-theft method is relatively complex in structure and has high production costs. The operation steps are too complicated. Figure 1As shown, although this automobile awning clamp (authorization announcement number: CN220314691U) realizes encryption, it is necessary to open the left half shell 51 and the right half shell 52 to realize the disassembly, assembly and maintenance of the awning.

For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. The directional terms mentioned in the embodiments of the present application, such as "upper", "lower", "left", "right", "inside", "outside", etc., are only reference directions of the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present application, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present application. "Multiple" means at least two.

[0045] In the embodiments of the present application, "and / or" is only a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship. The terms "include", "comprise", "have" and their variations all mean "including but not limited to", unless otherwise specifically emphasized.

[0046] In order to solve the technical problems existing in the background technology, the inventor's design idea is to use a fastener of a specific structure and a corresponding wrench tool to achieve anti-theft. In the process of developing the anti-theft device, the applicant found that the existing wrench tool has a single function and only has the function of disassembling and assembling the fastener. The applicant's prior art: mounting structure, fully automatic car awning and vehicle luggage rack (authorization announcement number: CN217917584U), car awning (authorization announcement number: CN307540467S), car awning (authorization announcement number: CN307535137S), etc., all have the situation of manually starting the awning. Inspired by this, the inventor thought about whether it is possible to combine the tool for manually starting the awning (unfolding the awning and storing the awning) with the anti-theft tool, and design a tool that can achieve both encryption and starting the awning.

[0047] Therefore, the present invention has two purposes: (1) to solve the problem that the existing anti-theft structure is relatively complex in structure, the device cost is high, and the operation steps are too complicated. (2) to solve the problem that the wrench tool of the prior art has a single function.

[0048] In order to achieve the above-mentioned purpose, the utility model provides a multifunctional anti-theft wrench for a car awning. Figure 2 and Figure 3 As shown, the multifunctional anti-theft spanner for the automobile awning comprises a handle 10 , an anti-theft connector 20 , a start connector 30 , an assembly port 11 and a rocker arm 40 .

[0049] The handle 10 extends in a straight line direction to form a strip structure with a gradually decreasing cross-sectional area from one end to the other end. The anti-theft joint 20 may adopt a sleeve structure, the internal shape of which is adapted to a fastener of a specific structure, and is arranged at one end of the handle 10 and hinged to the handle 10. Of course, the structure of the fastener needs to be innovatively designed, and its size or shape should be differentiated from the fasteners on the market, so that encryption can be achieved.

[0050] The purpose of setting the anti-theft joint 20 and the starting joint 30 to be hinged with the handle 10 is to appropriately adjust the angles of the anti-theft joint 20 and the starting joint 30 when the anti-theft joint 20 or the starting joint 30 is activated to realize the corresponding function, so as to facilitate the operation.

[0051] The starter joint 30 is located at the other end of the handle 10 and is hinged to the handle 10, and is used to be sleeved on the drive shaft and drive the drive shaft to rotate. The starter joint 30 can also be a sleeve structure, and its internal structure is compatible with the shape and structure of the starter joint 30.

[0052] The assembly opening 11 is provided on the handle 10 . The rocker arm 40 can be installed at the assembly opening 11 or removed from the assembly opening 11 .

[0053] Based on the setting of the anti-theft joint 20, only the fasteners adapted thereto can be opened, thus realizing the encryption function. Based on the setting of the start joint 30, it can be sleeved on the drive shaft to realize the manual driving of the drive shaft. The utility model combines the anti-theft tool and the manual driving tool together, realizes multiple uses of one tool, improves the utilization rate of the tool, and reduces the economic cost of the user.

[0054] The cross-sectional area of ​​the handle 10 gradually decreases from the end where the start connector 30 is assembled to the end where the anti-theft connector 20 is assembled. This can reduce material costs and achieve lightweighting of the tool.

[0055] In a preferred embodiment, the assembly opening 11 is a threaded hole that passes through the handle 10. A stud 41 that matches the threaded hole extends from one end of the rocker arm 40. The matching of the threaded hole and the stud facilitates the disassembly and assembly of the rocker arm 40.

[0056] Further, the assembly opening 11 is located on the handle 10 near one end of the anti-theft joint 20. The purpose of this arrangement is to increase the force arm when the awning is manually started.

[0057] The following further describes how the anti-theft connector 20 and the start connector 30 are rotatably connected to the handle 10.

[0058] For the anti-theft connector 20, Figure 2 As shown, the head end of the anti-theft joint 20 is provided with a groove 21 (i.e., the internal structure of the sleeve) adapted to a specific fastener, and the tail end is provided with a first pin hole 22. The end of the handle 10 corresponding to the anti-theft joint 20 is provided with a second pin hole (not marked in the figure) adapted to the first pin hole 22, and the first pin shaft 23 is inserted into the first pin hole 22 and the second pin hole at the same time to realize the hinged connection between the anti-theft joint 20 and the handle 10.

[0059] For the starter connector 30, Figure 2As shown, the tail end of the start joint 30 is provided with a second pin hole 31. The end of the handle 10 corresponding to the start joint 30 is provided with a third pin hole (not marked in the figure) adapted to the second pin hole 31. The second pin shaft 32 is inserted into the second pin hole 31 and the third pin hole at the same time to realize the hinge connection between the start joint 30 and the handle 10.

[0060] Based on the configuration of the hinge structure, the anti-theft joint 20 and the start joint 30 can only rotate in one direction. In other words, the anti-theft joint 20 and the start joint 30 have only one degree of freedom.

[0061] The rocker arm 40 is used as a force point (holding point) for driving the starter connector 30 to rotate, and plays a role when the starter connector 30 is activated. When the anti-theft connector 20 is activated, it needs to be removed. In order to increase the load distance when installing and removing specific fasteners and reduce the force required for users to tighten or remove fasteners, in an optional specific embodiment, as shown in FIG. Figure 5 As shown, a plug connector 42 adapted to the start connector 30 is provided at the other end of the rocker arm 40 where the stud 41 is provided. Figure 6 As shown, specifically, when the anti-theft joint 20 is activated, the rocker arm 40 is removed from the assembly port 11, and the rocker arm 40 is assembled to the start joint 30 through the plug joint 42. This can increase the load distance and the output torque.

[0062] like Figure 4 As shown, the anti-theft joint 20 is provided with a clearance notch 24 on one side of the hinge rotation direction. The clearance notch 24 is used to limit the rotation angle range of the anti-theft joint 20. Preferably, the rotation angle range of the anti-theft joint 20 is 0°-90°. Figure 1 As shown in FIG. 1 , when the anti-theft connector 20 is rotated clockwise, based on the setting of the clearance notch 24, the anti-theft connector 20 can be 90° with the handle 10. Figure 2 This is the initial state. Since the other side wall of the anti-theft connector 20 is not provided with a clearance notch, when the axis of the anti-theft connector 20 rotates to be in line with the handle 10, it cannot be rotated further.

[0063] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other, and any combination of features in different embodiments is also within the protection scope of this application, that is, the multiple embodiments described above can also be combined arbitrarily according to actual needs. All the above drawings are illustrative illustrations of this application and do not represent the actual size of the product, and the dimensional ratio relationship between the components in the drawings is not intended to limit the actual product of this application.

[0064] The above are only some embodiments and implementation methods of the present application, and the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by any person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
