The hinge structure of the present embodiment will be described with reference to fig. 2 to 4. Fig. 2 is a plan view showing the overall structure of the center rail and the center hinge according to the present embodiment. Fig. 3 is a schematic diagram showing the structure of the hinge in the present embodiment, and is a diagram viewed from the left side of fig. 2. Fig. 4 is a sectional view taken along line B-B of fig. 3.
As shown in fig. 2, the center hinge 150 includes: a bracket 1, the bracket 1 being fixed to the sliding door 300; an arm 2, the arm 2 being hinged to the support 1 by means of a hinge pin 3; and a roller 5, the roller 5 being rotatably supported by the arm 2 and being slidable on a middle rail 120 provided in a vehicle body 200 (see fig. 1). Specifically, as shown in fig. 3, the bracket 1 includes a fixing portion 11 fixed to the sliding door 300 (see fig. 1) and two protruding portions 12a, 12b (collectively referred to as the protruding portions 12 when the protruding portions 12a, 12b are not distinguished) protruding from the fixing portion 11. The arm 2 is a U-shaped member formed by bending a single plate, and the projections 12a and 12b are sandwiched from the outside of the projections 12a and 12 b. The arm 2 has attachment portions 21a, 21b opposed to the projection 12 in the axial direction of the hinge pin 3 (that is, both end portions of the U-shape sandwiching the projection 12a, 12b, and when the attachment portions 21a, 21b are not distinguished, they are collectively referred to as the attachment portions 21). First holes 22 through which the hinge pins 3 are inserted are formed in the mounting portions 21a, 21b, respectively, and second holes 13 through which the hinge pins 3 are inserted are formed in the protruding portions 12a, 12b, respectively.
As shown in fig. 3 and 4, two bushes 4a and 4b (collectively called bushes 4 when the bushes 4a and 4b are not distinguished) are provided corresponding to both ends of the hinge pin 3. The bush 4 has an annular portion 41 and a cylindrical portion 42, the annular portion 41 being interposed between the mounting portion 21 and the projection portion 12, and the cylindrical portion 42 being interposed between the hinge pin 3 and the projection portion 12 in the second hole 13. The annular portion 41 and the cylindrical portion 42 of each of the two bushes 4a and 4b are formed separately. In the present embodiment, the cylindrical portions 42 of the two bushes 4a, 4b are formed integrally, that is, the cylindrical portions 42 are formed so as to cover the hinge pin 3 from the portion corresponding to the annular portion 41 of the bush 4a to the portion corresponding to the annular portion 41 of the bush 4 b. As shown in fig. 4, in the present embodiment, the ring width W1 of the ring-shaped portion 41 is equal to or more than half the difference between the shortest distance D1 from the center of the first hole 22 to the outer edge of the mounting portion 21 and the radius R1 of the first hole.
(effects of the embodiment)
The effects of the present embodiment will be described with reference to comparative examples shown in fig. 5 and 6.
Fig. 5 is a schematic diagram of a hinge structure as a comparative example, corresponding to fig. 3 of the present embodiment. Fig. 6 is a sectional view taken along line a-a of fig. 5, corresponding to fig. 4 of the present embodiment. In the comparative example, the same portions as those in the present embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.
As shown in fig. 5 and 6, the comparative example is different from the present embodiment in the structure of the bush 4'. Specifically, the bushings 4a 'and 4 b' of the hinge structure of the comparative example are each integrally formed with the annular portion 41 'and the cylindrical portion 42'. The length of the cylindrical portion 42 ' of each of the bushes 4a ', 4b ' is only slightly longer than the length of the second hole 13 in the axial direction of the hinge pin, and is not integrally formed. The ring width W2 of the ring-shaped portion 41' is less than half of the difference between the shortest distance D1 from the center of the first hole 22 to the outer edge of the mounting portion 21 and the radius R1 of the first hole.
In the comparative example of the above structure, the bush 4 'is integrally molded, that is, when the bush 4' is manufactured, one end of the cylindrical portion 42 'is bent radially outward to form the annular portion 41'. Therefore, the annular portion 41' having a large annular width cannot be formed due to the limitation of formability. In this case, when the weight of the sliding door is heavy, the load applied to the roller 5 is large, and accordingly the load applied to the bush 4' is also large. Since the contact area of the annular portion 41' with the mounting portion 21 and the projecting portion 12 is small, the surface pressure of the contact surface is large, and these components are easily worn at the contact portion.
In contrast, in the preferred embodiment of the present invention, since the annular portion 41 and the cylindrical portion 42 of the bush 4 are formed separately, the annular width W1 of the annular portion 41 can be easily formed larger without being limited by moldability, as compared with the case of integrally molding the bush 4' in the comparative example. Thus, the contact area between the mounting portion 21 and the annular portion 41 is increased, and the surface pressure of the contact surface is reduced, whereby the wear resistance of the portion is further improved, and the durability can be reliably ensured even when the weight of the sliding door is heavy.
In addition, in the preferred embodiment of the present invention described above, since the cylindrical portions 42 of the two bushes 4a, 4b are integrally formed, when the annular portion 41 and the cylindrical portion 42 are formed separately, the increase in the number of components can be minimized, and the production and assembly costs can be reduced.
