An appropriate gap is maintained between the plurality of ball housing portions 32 and the holding member 321 and the plurality of balls 33, so that the plurality of the balls 33 can be freely rotated in the ball housing portion 32 without interference.

Since the ball slide rail of the present invention is an arc-shaped slide rail, the two partition plates 31 of the ball cage 30 are also designed to have a curved arc shape matching the first side wall 12 and the second side wall 21, and thus are retained by the ball. The plurality of ball housing portions 32 on the two partition plates 31 of the device 30 can hold the plurality of balls 33 in an arc-shaped moving path.

As shown in FIG. 1 , FIG. 2 and FIG. 4 , after the slide rail body 10 , the moving member 20 , and the ball retainer 30 of the present invention are combined, the two first side walls 12 of the slide rail body 10 and the two moving parts 20 are The two side walls 21 and the two partition plates 31 of the ball retainer 30 respectively have a matching curved curve, and the first side wall 12, the second side wall 21 and the partition plate 31 have the same arc center with each other, thus making the The moving member 20 and the ball retainer 30 are reciprocally displaceable within the arcuate guide groove 14 of the slide rail body 10 without causing interference.

As shown in FIG. 1 and FIG. 2, the rail body 10 is located at two ends of the curved guiding groove 14, and is respectively provided with a stopping portion 15 for preventing the moving member 20 and the sliding rail body 10 from being separated from each other. In this embodiment, the two stopping portions 15 are two vertical plates disposed at two ends of the curved plate body 11 and perpendicular to the curved plate body 11, and the two stopping portions 15 are disposed on the curved guiding grooves. 14 at the ends of the opening, thus being able to block the moving member 20 from the The openings at both ends of the curved guide groove 14 pass to prevent the moving member 20 from being separated from the slide body.

The molding and manufacturing method of the curved slide rail of the present invention is summarized as follows. The molding method of the slide rail body 10, the moving member 20, and the ball retainer of the present invention is preferably formed, but is not limited to the following two modes. First, since the curved slide rail of the present invention is made of a metal plate, the main components such as the slide rail body 10, the moving member 20, and the ball retainer 30 are mainly formed by a press forming technique. In the first molding method, after the linear slide rail body 10, the moving member 20, and the ball retainer 30 are first formed by the press method, the slide rail body 10, the moving member 20, and the ball are further bent by a bending die. The holder is bent in a predetermined bending direction to form a structure having a predetermined curved arc shape. In another molding method, the curved plate body 11 and the two first side walls 12 of the sliding rail body 10 are directly formed by a stamping method, and the curved plate body 11 and the first side wall 12 are formed to form a predetermined bending. The first ball guiding groove 13 is formed on the two first side walls 12 by side punching or rolling, and the moving member 20 and the ball holder 30 are similarly pressed in the same manner. After forming the second side wall 21 and the partitioning plate 31 having a curved curvature, the second ball guiding groove 22 is formed on the second side wall 21 by side punching or rolling, and the ball is formed on the partitioning plate 31. The housing portion 32.

Another design focus of the curved ball slide of the present invention is that the length of the ball retainer 30 and the length of the moving member 20 and the moving distance thereof have the following relationship. The two spacers 31 of the ball retainer 30 hold the balls 33 between the first side wall 12 and the second side wall 21, so that when the moving member 20 slides in the curved guiding groove 14, the respective balls 33 simultaneously contact the first a ball guiding groove 13 and a second ball guiding groove 22, so that the moving path of each of the balls 33 by the moving member 20 to roll along the first ball guiding groove 13 and the second ball guiding groove 22 is equal to the moving member 20 moves the path to half the length. Therefore, according to the above relationship, the length of the partitioning plate 31 of the ball retainer 30 must be greater than half the length of the reciprocating displacement path of the moving member 20 in the arcuate guiding groove 14 plus the length of the second side wall 21 of the moving member 20. Sum to keep the balls A sufficient number of balls 33 are held on the device 30 so that the second ball guiding groove 22 on the second side wall 21 of the moving member 20 can be held and fixed when the moving member 20 is moved to any position within the curved guiding groove 14. The number of balls 33 are in contact with each other so that the sides of the moving member 20 can obtain stable support of the balls 33.

The relationship between the length of the partition plate 31 of the ball retainer 30 and the moving member 20 and its moving distance can be expressed by the following mathematical expression: Lh ≧ 1/2 x Lc + Lm, where: Lh is the length of the ball retainer; Lc is the moving part The moving distance of 20; Lm is the length of the moving member 20.

As shown in FIGS. 5 and 6, a specific application embodiment of the curved ball slide of the present invention is applied to the bracket of the display of the present invention. In this embodiment, the display bracket has a base 1 and a curved bracket 2 disposed above the base 1. The inner side of the curved bracket 2 has a receiving portion, and the two portions of the receiving portion are arranged side by side. The arc-shaped ball slide rail of the invention is disposed in the accommodating portion, and a hinge base 3 is disposed in the accommodating portion of the arc-shaped bracket 2 and located between the two rail body 10, the skein The two sides of the chain base 3 are connected to the moving member 20 by screwing. The hinge base 3 is further provided with a pivoting seat 4, and is connected to the display fixing plate 5 through the pivoting base 4.

The display fixing plate 5 is connected to the moving member 20 of the two curved ball bearing rails of the present invention through the hinge base 3, and cooperates with the sliding rail body 10 through the moving member 20, so that the hinge base 3 and the display fixing plate 5 are matched. It can be guided by the rail body 10 to be displaced up and down along the curved path.

Through the curved ball slide rail of the present invention, an arc-shaped guiding path of the electronic product can be provided, so that moving parts of the electronic product, such as a display panel, a sliding cover, etc., can be disposed in the electronic product in an arc-shaped moving path. Fixed to the base or body, thus making the curved ball slide of the present invention particularly suitable for use in the most popular curved or curved televisions in the electronics industry today, or other electronic products having curved sliders or curved moving components. Therefore, the compatibility of the ball slide and the electronic product of the moving member of the type having the curved guiding path is improved.
