Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and in particular to a traction device and a tractor. Background Art

[0002] In the transportation scenario, the traction device is an important component used to connect the tractor and the towed mechanism. The performance of the traction device greatly affects the safety and efficiency of the transportation process. Figure 1 The towing hook 1 includes a shaft portion 1a, a hook body portion 1b and an assembly screw portion 1c, which is connected to the vehicle for towing through the assembly screw portion 1c, and is connected to the towed vehicle through the hook body portion 1b. In actual use, especially in scenarios such as connecting a tractor and a luggage trailer at an airport where frequent connection and release of the towing device are required, the towing hook has at least the following defects: if only one towing hook is used for connection, the towing hook is subjected to greater force, which causes more severe wear on the towing hook, resulting in poor durability; and if multiple towing hooks are provided separately, multiple connection operations are required during use, which is less convenient to use. It can be seen that it is impossible to achieve a balance between durability and convenience of use. Utility Model Content

DETAILED DESCRIPTION

[0023] Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings.

[0024] Combination Figures 2 to 6 As shown, the embodiment of the present application provides a traction device, including a mounting seat 10, at least two traction plates 20, a connector 30 and a connector release mechanism 40. The at least two traction plates 20 are vertically mounted on the mounting seat 10, and a gap for accommodating the traction mechanism is provided between the at least two traction plates 20. The at least two traction plates 20 are each provided with a traction hole 200 penetrating the traction plate, and the traction holes 200 of the at least two traction plates 20 are coaxially arranged. The connector release mechanism 40 is connected to the connector 30, and is used to insert the connector 30 into the traction hole 200 and the traction hole of the traction hole mechanism, or to extract the connector 30 from the traction hole 200 and the traction hole.

[0025] During use, the connector 30 is inserted into the coaxial traction hole 200 and the towed hole by controlling the connector release mechanism 40 to realize the connection process; the connector 30 is pulled out from the coaxial traction hole 200 and the towed hole by controlling the connector release mechanism 40 to realize the release process. The multiple traction plates 20 can disperse the tension on the traction device during use, which is beneficial to reduce the wear of local components and improve the durability of the traction device. At the same time, the mounting seat 10 vertically connected to the multiple traction plates 20 can further disperse the tension on the traction plate 20 and further improve the durability of the traction device. In addition, the multiple traction holes 200 arranged coaxially can be passed through by the connector 30 in sequence, without multiple connection operations, and the connector 30 can be quickly positioned and fixed, which is beneficial to improve the convenience of the traction device during use. Therefore, the traction device provided by the present application achieves a balance between durability and ease of use, and optimizes the performance of the traction device.

[0026] In some embodiments, the thickness of the traction plate 20 ranges from 48 mm to 52 mm. In this way, limiting the thickness of the traction plate 20 within a suitable range can prevent the traction plate 20 from being too thin, resulting in concentrated force and easy wear, and from being too thick, resulting in unnecessary weight and material redundancy.

[0027] In some embodiments, the traction hole 200 is a circular hole, and the diameter of the traction hole 200 ranges from 50 mm to 54 mm. This arrangement can avoid the traction hole 200 being too small, resulting in too few adapted traction mechanisms, or the adapted connector 30 being too thin and having poor bearing capacity, and can also avoid the traction hole 200 being too large, resulting in the connector 30 being unstable in the traction hole 200 and unable to achieve a stable connection.

[0028] In some embodiments, the traction hole 200 and the towed hole are both circular holes, the cross section of the plug-in component 30 is circular, and the diameter of the plug-in component 30 is smaller than the diameters of the traction hole 200 and the towed hole. In this way, the plug-in component 30 can be ensured to pass through the traction hole 200 and the towed hole smoothly without being blocked, and the circular hole does not limit the insertion direction of the plug-in component 30, which is conducive to optimizing the convenience of the use process. In other embodiments, the traction hole 200 can also be set as an elliptical hole, a semicircular hole, etc. according to actual application requirements.

[0029] In some embodiments, the traction device includes more than three traction plates 20, which are evenly spaced, and a gap for accommodating the traction mechanism is provided between adjacent traction plates 20. In this way, providing more than three traction plates 20 is conducive to distributing the pulling force to each traction plate 20, thereby reducing the wear on the traction device and the traction mechanism, and improving the durability of the traction device. At the same time, arranging multiple traction plates 20 at equal distances can improve the uniformity of the force on each traction plate 20 and the traction mechanism, which is conducive to reducing the wear of the device caused by uneven force, thereby further improving the durability of the traction device.

[0030] In some embodiments, the traction device includes three traction plates 20. Compared with the arrangement of two traction plates 20, this is conducive to further dispersing the pulling force, achieving the technical effect of reducing device wear and improving the durability of the traction device; at the same time, it avoids the marginal effect of too many traction plates 20, thereby improving the utilization rate of the traction plates 20 while optimizing the durability of the traction device.

[0031] Here combined Figure 3 An example is given for the case where the traction device includes three traction plates 20. The traction device includes a first traction plate 21, a second traction plate 22, and a third traction plate 23, and the first traction plate 21 includes a first traction hole 210, the second traction plate 22 includes a second traction hole 220, and the third traction plate 23 includes a third traction hole 230. The first traction hole 210, the second traction hole 220, and the third traction hole 230 are coaxially arranged.

[0032] It should be noted here that, in the description of this application, the terms "first", "second", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.

[0033] In some embodiments, the spacing between adjacent traction plates 20 is greater than the thickness of the traction plates 20. In this way, it is possible to avoid the spacing between the traction plates 20 being too small, which causes the connector 30 to be subjected to a relatively concentrated force, and it is beneficial to further disperse the forces of each traction plate 20 and the connector 30, thereby reducing wear and improving durability.

[0034] Furthermore, in some embodiments, the distance between adjacent traction plates 20 ranges from 68 mm to 72 mm. Figure 3In the embodiment, the spacing between the first traction plate 21 and the second traction plate 22 is the same as the spacing between the second traction plate 22 and the third traction plate 23, and both are between 68 mm and 72 mm. In this way, on the one hand, it can prevent the traction plates 20 from being too concentrated, resulting in a poor effect of dispersing the force; on the other hand, it can prevent the traction plates 20 from being too dispersed, resulting in the need for an overly long connector 30 to achieve the connection between the traction plate 20 and the traction mechanism, which is beneficial to saving materials, avoiding excessive redundancy of materials, and preventing deformation of the connector 30, thereby improving the durability of the connector 30.

[0035] Continue to combine Figure 2 and Figure 3 In some embodiments, the traction plate 20 is an isosceles trapezoidal plate, and the bottom of the isosceles trapezoidal plate is connected to the mounting seat 10. The setting of the isosceles trapezoidal plate is adapted to the force direction of the traction hole 200 when being pulled, which is conducive to improving the utilization rate of the traction plate 20 material and avoiding material redundancy.

[0036] Furthermore, the ratio of the length of the upper base to the length of the lower base of the isosceles trapezoidal plate ranges from 0.48 to 0.52. In this way, the specific shape of the isosceles trapezoidal plate is adapted to the force direction when being pulled, which, on the one hand, avoids the upper base being too long, so that the two corner areas of the upper base are not subjected to force or are subjected to less force during actual use, resulting in low utilization of the material in this part; on the other hand, avoids the lower base being too long, so that the two corner areas of the lower base are not subjected to force or are subjected to less force during actual use, resulting in low utilization of the material in this part. In this way, the utilization of the traction plate is optimized by further limiting the shape of the isosceles trapezoidal plate.

[0037] In some embodiments, the length of the lower base of the isosceles trapezoidal plate ranges from 170 mm to 210 mm. In this way, the length of the lower base of the isosceles trapezoidal plate is limited to a specific range of values, so as to specifically limit the shape of the isosceles trapezoidal plate suitable for the traction device, avoid the lower base length of the isosceles trapezoidal plate being too short to achieve a good tension dispersion effect, and avoid the lower base length being too long to cause unnecessary material redundancy.

[0038] When the traction hole 200 is a circular hole, the center of the circular hole passes through the line connecting the upper and lower midpoints of the isosceles trapezoidal plate. This helps to make the forces on both sides of the traction plate 20 even, thereby avoiding unilateral wear, improving the durability of the traction device, and ensuring stability during use.

[0039] In some embodiments, the ratio of the upper base length of the isosceles trapezoidal plate to the diameter of the traction hole 200 is in the range of 1.58 to 1.62. In this way, the correspondence between the upper base length and the size of the traction hole 200 is defined to avoid the upper base length being too long relative to the traction hole 200, resulting in material redundancy, and to avoid the upper base length being too short relative to the traction hole 200, resulting in a reduced load-bearing capacity during the traction process.

[0040] In some embodiments, the ratio of the minimum distance between the traction hole 200 and the upper bottom of the isosceles trapezoidal plate to the diameter of the traction hole 200 is in the range of 1.07 to 1.2. In this way, by limiting the opening position of the traction hole 200 in the isosceles trapezoidal plate, it is possible to avoid the opening position of the traction hole 200 being too close to the upper bottom of the isosceles trapezoidal plate, thereby avoiding excessive concentration of the actual force area during use, and improving the durability of the isosceles trapezoidal plate.

[0041] In some embodiments, the minimum distance between the traction hole 200 and the upper bottom of the isosceles trapezoidal plate is in the range of 58 mm to 60 mm. Here, further quantitative restrictions are made on the setting position of the traction hole 200, which can prevent the traction hole 200 from being too close to the upper bottom of the isosceles trapezoidal plate, thereby increasing the force-bearing area in the traction plate, dispersing the pressure, and improving the durability of the traction device.

[0042] In other embodiments, the traction plate 20 may also be a semicircular plate, a semi-elliptical plate, or a polygonal plate such as a rectangle.

[0043] Combination Figure 5 and Figure 6 , the connector release mechanism 40 is further described. In some embodiments, the connector release mechanism 40 includes a rotating portion and a connecting portion 42, and the connecting portion is controlled to rotate around the rotating portion to drive the connector to be inserted into the traction hole 200 and the towed hole, or to be pulled out from the traction hole 200 and the towed hole. The connector release mechanism 40 is connected to the tractor body, specifically, the connecting portion 42 is connected to the tractor body. In this way, the movement of the connector 30 is controlled by setting the rotating portion and the connecting portion 42, and a convenient traction and release process can be completed.

[0044] More specifically, in some embodiments, a plurality of rotating parts and connecting parts 42 are provided. Figure 5 , Figure 6In the illustrated embodiment, the connector release mechanism 40 includes a first rotating portion 411 and a second rotating portion 412, and is provided with a plurality of interconnected connecting portions 42, wherein the plurality of connecting portions 42 are interconnected through the first rotating portion 411 and the second rotating portion 412. When the connector 30 needs to be inserted into or withdrawn from the traction hole 200, an external force is applied to the connecting portion 42 near one side of the connector 30, so that the connecting portion 42 near the first rotating portion 411 rotates along the first rotating portion 411, and the connecting portion 42 near the second rotating portion 412 rotates along the second rotating portion 412, so as to insert or withdraw the connector 30 from the traction hole 200. In some embodiments, the connector release mechanism 40 is further provided with an intermediate connecting component 43 for connecting adjacent connecting portions 42, which may be a movable connecting component or a fixed connecting component. In the process of applying an external force to the connecting portion 42 near one side of the connector 30, the intermediate connecting component 43 adaptively changes position with the movement of the connecting portion 42. When the current operation is to release the traction device, that is, to pull the connector 30 out of the traction hole 200, the rotation of the connecting portion 42 is as follows: Figure 5 as well as Figure 6 The current operation is to connect the traction device, that is, when the connector 30 is pulled out from the traction hole 200, the rotation of the connecting part 42 is the same as that of the connecting part 42. Figure 5 as well as Figure 6 In some embodiments, the first rotating portion 411 and the second rotating portion 412 are hinges.

[0045] In some embodiments, the connector release mechanism further includes a gripping portion 41, which is disposed on the connecting portion 42 to drive the connecting portion 42 to rotate around the rotating portion. In this way, it is convenient for the user to control the connector release mechanism, thereby improving the convenience of using the traction device. Specifically, the gripping portion can be Figure 5 In other embodiments, the gripping portion 41 may be a bump, a groove or other structure that can be gripped by a user, without specific limitation.

[0046] In some embodiments, the aforementioned mounting seat 10 is directly connected to the tractor body. For example, the mounting seat 10 can be welded to the frame of the tractor body to achieve a stable connection between the traction device and the tractor.

[0047] In some embodiments, in combination Figures 2 to 6 The traction device further includes a base 50. The base 50 is mounted on the tractor body, and the mounting seat 10 is mounted on the base 50. The width of the mounting seat 10 is less than or equal to the width of the base 50, and the length of the mounting seat 10 is less than or equal to the length of the base 50. In this way, the mounting seat 10 can be integrally arranged on the base 50, which is conducive to improving the stability of the overall structure of the traction device, thereby improving the carrying capacity of the traction device. At the same time, it can further disperse the pulling force, play a role in reducing wear, and thus improve the durability of the traction device.

[0048] In some embodiments, the width of the base 50 ranges from 180 mm to 220 mm, and the length of the base 50 ranges from 480 mm to 500 mm.

[0049] In practical applications, the base 50 is made of channel steel and welded to the frame of the tractor body. Channel steel is a long steel strip with a groove shape. This is beneficial to improving the structural stability of the traction device.

[0050] In some embodiments, the base 50 is vertically disposed on the ground, and a groove 500 is formed on the upper portion of the base 50. The groove 500 is provided to provide a receiving space for the connector release mechanism 40, so as to facilitate the activity of the connector release mechanism 40, so as to drive the connector 30 to move and release or tow the towed mechanism.

[0051] In some embodiments, the traction device further includes a limiting mechanism 60, which is mounted on the traction plate 20 and is arranged around the traction hole 200. The limiting mechanism 60 is provided with a hinge for connection and fixing. In this way, the fiber mechanism 60 is conducive to achieving accurate positioning of the connector 30, and plays a further limiting role, thereby improving the convenience of operation of the traction device and the stability of the connector 30 during use.

[0052] In some embodiments, part or all of the above-mentioned traction device is made of 45 steel, which is a medium-carbon structural steel with a carbon content of about 0.45%, which is conducive to improving resistance to adverse weather conditions that may occur during use, thereby extending the service life.

[0053] In some embodiments, part or all of the surface of the above-mentioned traction device is painted to protect the internal structure, which is beneficial to improve resistance to adverse weather conditions that may occur during use, thereby extending the service life.

[0054] It should be noted that when an element is referred to as being "fixed to", "disposed on", "fixedly arranged on" or "installed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. Furthermore, when an element is considered to be "fixedly connected to" another element, the two may be fixed in a detachable connection manner or in a non-detachable connection manner, such as socketing, snap-fitting, integral molding, welding, etc., which can be achieved in traditional technologies and will not be repeated here.
