Description

Technical Field

[0001] The utility model belongs to the technical field of automobile door lock structures, in particular to a mechanical door unlocking mechanism for an all-terrain vehicle. Background Art

[0002] All-terrain vehicles are vehicles that can travel on any terrain and can move freely on terrain that is difficult for ordinary vehicles to maneuver. In my country, they are commonly known as beach buggies or farmer's carts. This type of vehicle has wide tires that can increase the contact area with the ground, generate greater friction and reduce the pressure of the vehicle on the ground, making it easy to travel on beaches, riverbeds, forest roads, streams, and harsh desert terrains.

[0003] Door locks are important safety components of cars, and generally include an unlocking mechanism. The function of the unlocking mechanism is to release the locked state of the door when the door is in the locked position. Common types include mechanical and electronic types. The mechanical unlocking mechanism achieves the above function through a simple lever movement.

[0004] Because all-terrain vehicles often travel on rugged roads, their working conditions are worse than those of ordinary cars. When using the mechanical door unlocking mechanism, drivers and passengers are often more likely to continue to use force to pry the handle of the mechanical door unlocking mechanism, causing the elastic parts and locking plates of the mechanical door unlocking mechanism to deform; and once the elastic parts and locking plates are deformed, the locking of the door lock will no longer be reliable, and it will automatically disengage under a certain impact force, causing adverse effects on the life safety of the drivers and passengers of the all-terrain vehicles. Utility Model Content

[0005] In view of the shortcomings of the prior art described above, the purpose of the present utility model is to provide a mechanical door unlocking mechanism for an all-terrain vehicle, which is used to solve the problem in the prior art that since all-terrain vehicles often travel on rough roads, drivers and passengers are more likely to continuously use force to pry the handle of the mechanical door unlocking mechanism, thereby causing deformation of the elastic parts and locking plates of the unlocking mechanism.

[0006] To achieve the above-mentioned purpose and other related purposes, the utility model provides a mechanical door unlocking mechanism for an all-terrain vehicle, comprising a fixed plate installed on the door and a handle hinged on the fixed plate, wherein the handle pulls a lock plate to control the door lock to open through a pull rod, and the handle returns to its original position through an elastic member, and also comprises a limiting component, which limits the rotation angle of the handle; the limiting component comprises a limiting block arranged on the handle and two limiting blocks arranged on the fixed plate, and when the handle is rotated to the maximum limited angle, the limiting block and the two limiting blocks conflict with each other.

[0007] Optionally, the locking plate is hinged to the pull rod, and is also hinged to the door lock via a connecting plate, and a stabilizing plate is mounted on the connecting plate.

[0008] Optionally, it also includes a rotating shaft, a handle groove is opened in the middle of the fixed plate, and a first ear and a second ear are respectively provided on the upper and lower sides of the handle groove; the rotating shaft passes through the first ear and the second ear, and the handle is hinged between the first ear and the second ear through the rotating shaft.

[0009] Optionally, the handle is in a "Z" shape, the first limit block is arranged on the lower side of the handle, and the second limit block is arranged on the left side of the second support ear.

[0010] Optionally, the bottom of the second ear is fixedly connected to the lower side of the handle groove, and the length of the second ear is greater than two-thirds of the length of the lower side of the handle groove.

[0011] Optionally, a third lug extending downward is provided on the second lug, and the elastic member is a tension spring, and two ends of the tension spring are respectively connected to the limiting block and the third lug.

[0012] Optionally, two ends of the pull rod are hinged to the upper part of the handle and the locking plate respectively.

[0013] Optionally, a stabilizing jacket is provided at the hinged end of the pull rod.

[0014] Optionally, the rotation angle of the handle is less than 30°.

[0015] Optionally, the rotation angle of the handle is less than 18°.

[0016] As described above, the mechanical door unlocking mechanism of an all-terrain vehicle of the present invention has at least the following beneficial effects:

[0017] 1. The mechanical door unlocking mechanism of the all-terrain vehicle includes a limiting block arranged on the handle and two limiting blocks arranged on the fixed plate through a limiting component. When the handle is rotated to the maximum limited angle, the limiting block and the limiting block conflict with each other, and the design of limiting the rotation angle of the handle prevents the handle from rotating too much, that is, prevents the elastic member from being stretched too much and the locking plate from being subjected to excessive pulling force, thereby reducing the probability of deformation of the elastic member and the locking plate, and solves the problem in the background technology that the all-terrain vehicle often travels on rough roads, and the driver and passengers are more likely to continue to use force to pry the handle of the mechanical door unlocking mechanism, thereby causing the elastic member and the locking plate of the unlocking mechanism to deform.

[0018] 2. The mechanical door unlocking mechanism of this all-terrain vehicle is hinged by a lock plate and a pull rod, and the lock plate is hinged by a connecting plate and a door lock. A stabilizing plate is installed on the connecting plate to improve the stability of the connecting plate and avoid excessive pressure from the pull rod, which pulls the door lock and causes the connection between the connecting plate and the lock plate to shake, affecting the function of the door lock and reducing the reliability of the door.

[0019] 3. The mechanical door unlocking mechanism of the all-terrain vehicle is fixedly connected by the bottom of the second ear and the lower side of the handle groove, and the length of the second ear is greater than two-thirds of the length of the lower side of the handle groove, which fully ensures the stability of the entire unlocking mechanism when the limit block installed on the lower side of the handle and the upper limit blocks of the second ear conflict with each other, thereby improving the reliability of the unlocking mechanism.

[0026] See also Figures 1 to 3. It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the utility model, so they have no substantial technical significance.

At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the utility model. Changes or adjustments in their relative relationships should also be regarded as the scope of the implementation of the utility model without substantially changing the technical content.

[0027] The following embodiments are only for illustration purposes and can be combined with each other, and are not limited to the contents presented in the following single embodiments.

[0028] See also Figure 1 The utility model provides a mechanical door unlocking mechanism for an all-terrain vehicle, comprising a fixing plate 1 installed on the door and a handle 2 hinged on the fixing plate 1, wherein the handle 2 pulls a locking plate 5 for controlling the door lock 4 to be opened through a pull rod 3, and the handle 2 is returned to its original position through an elastic member 6, and the handle 2 is limited in rotation angle by a limiting member 8, and the rotation angle of the handle 2 is less than 30°; the function of the design is to prevent the handle from rotating at an excessive angle, that is, to prevent the elastic member 6 from being stretched too much and the locking plate 5 from being applied with excessive pulling force, thereby reducing the probability of deformation of the elastic member 6 and the locking plate 5, and solving the problem in the background technology that the all-terrain vehicle often travels on a rugged road, and the driver and passengers are more likely to continuously use force to pry the handle 2 of the mechanical door unlocking mechanism, thereby causing the elastic member 6 and the locking plate 5 of the unlocking mechanism to deform.

[0029] like Figure 1 As shown, the lock plate 5 is hinged to the pull rod 3, and is also hinged to the door lock 4 through a connecting plate 41. A stabilizing plate 42 is installed on the connecting plate 41, which improves the stability of the connecting plate 41 as a whole and avoids the problem that the pull rod 3 applies excessive pressure and pulls the door lock 4, causing the connection between the connecting plate 41 and the lock plate 5 to shake, affecting the function of the door lock 4, and reducing the reliability of the door.

[0030] In another embodiment, see Figure 1 and Figure 2The mechanical door unlocking mechanism of the all-terrain vehicle also includes a rotating shaft 7, a handle groove 14 is opened in the middle of the fixing plate 1, and a first ear 11 and a second ear 12 are respectively arranged on the upper and lower sides of the handle groove 14; the rotating shaft 7 passes through the first ear 11 and the second ear 12, and the handle 2 is hinged between the first ear 11 and the second ear 12 through the rotating shaft 7. This embodiment provides a simple, firm and easy-to-produce structure in which the handle 2 is hinged on the fixing plate 1.

[0031] In another embodiment, see Figure 2 and Figure 3 The shape of the handle 2 is "Z"-shaped, and the folding angles of the adjacent handles 2 can be selected in time according to actual needs; the handle 2 is provided with a limiting block 81 extending downward, and the second support ear 12 is provided with two limiting blocks 82 extending to the left; when the handle 2 rotates at an angle greater than a limited angle, the limiting block 81 and the two limiting blocks 82 conflict with each other, that is, the limiting block 81 and the two limiting blocks 82 constitute the limiting component 8 of the mechanical door unlocking mechanism of the all-terrain vehicle. The limiting component 8 of the present embodiment has a simple structure. It only needs to add a protruding limiting block to each of the existing fixing plate 1 and the handle 2. The components required by the present structure can be obtained at a low cost through mold forming, stamping or machining.

[0032] It should also be noted that the limit piece 81 can also be obtained by extending the handle 2 upward, and other corresponding components are also adaptively adjusted, which will not be repeated here.

[0033] In another embodiment, see Figure 3 The rotation angle of the handle 2 is less than 18°, which is a more suitable rotation angle range of the handle 2 than the 30° selected above, and the elastic member 6 and the locking plate 5 are subjected to less destructive stress.

[0034] In another embodiment, see Figure 2 The bottom of the second ear 12 is fixedly connected to the lower side of the handle groove 14, and the length of the second ear 12 is greater than two-thirds of the length of the lower side of the handle groove 14, which fully ensures the stability of the entire unlocking mechanism when the limiting block 81 installed on the lower side of the handle 2 and the two upper limit blocks 82 of the second ear 12 conflict with each other, thereby improving the reliability of the unlocking mechanism.

[0035] In another embodiment, see Figure 2The second lug 12 is provided with a third lug 13 extending downward, the elastic member 6 is a tension spring, and the two ends of the tension spring are respectively connected to the limit block 81 and the third lug 13. The present embodiment provides a specific structural form and installation method of the elastic member 6. The tension spring can be made of standard parts with low cost. The design of the third lug 13 extending downward on the second lug 12 provides a stable installation base point for the tension spring, and no new parts are added, thereby ensuring the simplicity of the entire unlocking mechanism and facilitating subsequent maintenance or replacement.

[0036] In other embodiments, Figure 1 As shown, the two ends of the pull rod 3 are hinged to the upper part of the handle 2 and the locking plate 5 respectively, and the hinged end of the pull rod 3 is provided with a stabilizing sleeve 9, which further ensures the stability of the entire unlocking structure and the door lock 4 when the driver and passengers bend the handle 2 to unlock the door lock 4, and also improves the operability and comfort when the driver and passengers bend the handle 2.

[0037] In summary, the present invention adopts a limiting component including a limiting block 81 disposed on the handle 2 and two limiting blocks 82 disposed on the fixing plate 1. When the handle 2 is rotated to the maximum limiting angle, the limiting block 81 and the limiting block 82 conflict with each other, thereby limiting the rotation angle of the handle 2. This prevents the handle 2 from rotating too much, that is, prevents the elastic member 6 from being stretched too much and the locking plate 5 from being subjected to too much pulling force, thereby reducing the probability of deformation of the elastic member 6 and the locking plate 5, and solving the problem that the all-terrain vehicle in the background technology is often driven on a rough road. , the driver and passengers are more likely to continue to forcefully pry the handle 2 of the mechanical door unlocking mechanism, which causes the elastic member 6 and the lock plate 5 of the unlocking mechanism to deform; at the same time, the lock plate 5 is hinged with the pull rod 3, and the lock plate 5 is hinged with the door lock 4 through the connecting plate 41. The connecting plate 41 is equipped with a stabilizing plate 42, which improves the stability of the connecting plate 41 and avoids the pull rod 3 applying excessive pressure to pull the door lock 4, causing the connection between the connecting plate 41 and the lock plate 5 to shake, affecting the function of the door lock 4, and reducing the reliability of the door. Therefore, the utility model effectively overcomes the shortcomings of the prior art and has a high industrial utilization value.

[0038] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
