Description

Technical Field

[0001] This utility model relates to the field of seat bracket technology, and specifically to a seat bracket assembly. Background Technology

[0002] The seat support assembly includes a guide rail installed inside the car and a seat bracket that slides back and forth on the guide rail. The car seat is fixedly installed on top of the seat bracket. The fore-and-aft position of the car seat is adjusted by adjusting the fore-and-aft position of the seat bracket on the guide rail. After the position of the seat bracket on the guide rail is determined, the handle needs to be lifted upwards, which causes the push plate to move downwards, thereby opening the elastic plates on the left and right sides to engage with the grooves on the guide rail to achieve a fixed limit. This structure makes the positioning accuracy and stability of the seat bracket on the guide rail not high, and it is easy for it to loosen, resulting in insufficient seating stability of the car seat and affecting the user's riding experience.

[0030] See Figure 1-7 As shown in the figure, as an embodiment of the present invention, a seat bracket assembly is provided, including a seat bracket 2 and a guide rail 1. A car seat is mounted on the top of the seat bracket 2, and the seat bracket 2 is mounted on the guide rail 1 with adjustable front and rear positions. The guide rail 1 has a groove with an inverted T-shaped longitudinal section, which includes a limiting groove 11 and a clearance channel 12 vertically disposed above the middle of the limiting groove 11. Multiple arc-shaped notches 13 are provided on the left and right sides of the guide rail 1 corresponding to the clearance channel 12. Two arc-shaped notches 13 on the left and right sides are joined together to form a complete circular through hole. Limiting members 3 and limiting plate groups are respectively installed at the front and rear ends of the bottom of the seat bracket 2. The limiting members 3 are limited and cooperate with the circular through hole, and the limiting plate groups are limited and cooperate with the limiting groove 11. That is, the seat bracket 2 is fixed at multiple points on the guide rail 1 by the limiting plate groups and limiting members 3, so that the positioning accuracy and stability of the seat bracket 2 on the guide rail 1 are higher, and it is not easy to loosen. This makes the seating stability of the car seat higher and ensures the user's seating experience.

[0031] In this embodiment, the guide rail 1, the limiting member 3, and the limiting plate group are two that are arranged opposite each other on the left and right, which further improves the positioning accuracy and stability of the seat bracket 2 on the guide rail 1.

[0032] In this embodiment, the limiting member 3 includes a disc-shaped cap 31 and a limiting post 32 disposed below the cap 31. The limiting post 32 cooperates with the circular through hole for limiting, which enables more accurate and faster alignment operation. The cap 31 contacts the top surface of the guide rail 1 to form a support fit, ensuring support stability.

[0033] In this embodiment, the seat support 2 includes vertical frames 21 arranged side by side and curved plates 22 connecting the front and rear sides between the two vertical frames 21. The limiting member 3 and the limiting plate assembly are respectively installed at the front and rear ends of the vertical frames 21. This arrangement makes the overall connection strength and support strength of the seat support 2 higher.

[0034] In this embodiment, see Figure 2-4 As shown, the limiting plate assembly includes two symmetrically arranged elastic plates 4, a drive mechanism and a limiting pin 7 installed between the two elastic plates 4. The top side of the elastic plate 4 is the fixed side fixedly installed on the seat bracket, and the bottom side of the two elastic plates 4 is the free side that can elastically deform. The drive mechanism is used to drive the free sides of the two elastic plates 4 to open away from each other and clamp them in the limiting groove 11. The limiting pin 7 is used to block and limit the drive mechanism. Specifically, the opposite sides of the two elastic plates 4 are the inner sides, and the opposite sides are the outer sides. The free side of the elastic plate 4 includes an inclined plate body 41 and a snap-fit ​​plate body 42 provided at the bottom end of the inclined plate body 41. The inclined plate body 41 is gradually inclined inward from top to bottom, and the snap-fit ​​plate body 42 is gradually inclined outward from top to bottom. The drive mechanism includes a handle 5 and a push plate 6 that are in transmission cooperation. There are multiple push plates 6 arranged side by side. The handle 5 includes a handle rod 51 and a transmission rod 52 that are L-shaped to each other. The front top of the push plate 6 is hinged between the two elastic plates 4. The rear top is provided with a long slot 61, and the end of the transmission rod 52 away from the handle rod 51 is slidably set in the long slot 61 through a pin; the elastic plate 4 is provided with a clearance hole 8, and the limiting pin 7 is inserted through the clearance holes 8 of the two elastic plates 4 to block and limit the push plate 6. The clearance hole 8 is a V-shaped clearance hole with the opening facing the rear, and its top is formed with a suspension slot 81 for the limiting pin 7 to be suspended and placed. This makes it easier and faster for the user to operate without having to lift and hold the limiting pin 7 by hand the whole time when the seat bracket 2 is removed from the guide rail 1.

[0035] When the seat bracket 2 needs to be installed on the guide rail 1, first place the seat bracket 2 in the corresponding position on the guide rail 1, then the limiting member 3 engages with the circular through hole for limiting, and the free sides of the two elastic plates 4 are placed in the groove. Then, swing the handle rod 51 upward to lift it, causing the transmission rod 52 to swing downward, thereby driving the push plate 6 to move downward. This causes the free sides of the two elastic plates 4 to open away from each other under the pressure of the push plate 6, thus locking the snap-fit ​​plate 42 of the two elastic plates 4 into the limiting groove 11. Then, slide the limiting pin 7 to the bottom of the V-shaped clearance hole 8 to block and limit the push plate 6, thereby completing the process of fixing and limiting the seat bracket 2 on the guide rail 1. Figure 2As shown; when it is necessary to remove the seat bracket 2 from the guide rail 1, first slide the limiting pin 7 to the top of the V-shaped clearance hole and place it at the suspension slot 81, thereby releasing the limiting pin 7 from blocking the push plate 6. Then swing the handle rod 51 downward, so that the transmission rod 52 swings upward, thereby driving the push plate 6 to move upward, so that the free sides of the two elastic plates 4 approach and close each other under the action of the push plate 6's own elasticity. Lift the seat bracket 2 upward, so that the limiting part 3 exits the circular through hole and the limiting plate group exits the groove, thereby completing the process of removing the seat bracket 2 from the guide rail 1.

[0036] In this embodiment, the guide rail 1 has an arc-shaped concave surface 14 formed in the middle of the limiting groove 11, which can provide a certain clearance space for the movement of the snap-fit ​​plate 42 and avoid jamming.

[0037] In this embodiment, the handle rod 51 is covered with a handle sleeve 53, and one side of the handle sleeve 53 has a wavy grip surface, which allows the user to grip it and makes the operation easier and less strenuous.

[0038] In this embodiment, a wheel 9 is also installed on the vertical frame 21 located on the side of the limiting plate group away from the limiting member 3. The wheel 9 can swing up and down to adjust, so that the seat bracket 2 can be quickly and easily moved and transported after being removed from the guide rail 1. This facilitates the movement of goods placed on the seat of the seat bracket 2 or the movement of people with mobility impairments sitting on the seat of the seat bracket 2.

[0039] In this embodiment, a support plate 10 is also fixedly installed on the outer side of the elastic plate 4. The bottom of the support plate 10 cooperates with the surface of the guide rail 1 to ensure the stability of the seat bracket 2 on the guide rail 1.

[0040] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that any changes in form and detail made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims fall within the protection scope of the present invention.
