Description

Technical Field

[0001] This utility model belongs to the field of seat back technology, and in particular relates to a novel bus seat back. Background Technology

[0002] Bus seat backs are structures that provide support for passengers' backs. They are often made of a single material, such as all fabric, all leather, or plastic. In summer, breathable mesh panels are used to increase back ventilation, while in winter, leather or plastic materials with a better feel are used.

[0003] However, existing seat back structures are usually fixed, meaning that the seat back can only be installed with the seat and cannot be quickly switched. There is no convenient adjustment mechanism to adapt to seasonal changes, and it is impossible to achieve the function of "breathable in summer and warm in winter" through simple operation.

[0004] In view of this, we propose a new type of bus seat back. Utility Model Content

[0005] The purpose of this utility model is to provide a novel bus seat back to solve the problems mentioned in the background art.

[0006] In view of this, the present utility model provides a novel bus seat backrest, including a seat cushion, a backrest fixedly installed on the outer surface of the seat cushion, an accommodating cavity opened inside the backrest, a connecting mechanism provided inside the accommodating cavity, a fixing frame installed outside the connecting mechanism, and mounting frame one and mounting frame two respectively installed inside the fixing frame, a perforated plate installed outside the mounting frame one, and a leather plate installed outside the mounting frame two. Both sides of the backrest are fixedly installed with a fixing box. The fixing box has a sliding rod inside. A magnetic plate one is fixedly installed on the inner wall of the fixing box. A magnetic plate two is attracted to the outside of the magnetic plate one. A push plate is fixedly installed on the outer surface of the magnetic plate two.

[0007] In this technical solution, the perforated plate and leather plate can be used to switch between winter and summer. In summer, the perforated plate with better breathability is used on the seat back, while in winter, the more comfortable leather plate is used. The backrest can be quickly switched by rotating the fixing frame. Then, the fixing frame can be fixed by the insertion rod through the adsorption of magnetic plate one and magnetic plate two, which facilitates quick switching and improves stability during use.

[0008] In the above technical solution, the connecting mechanism further includes a support ring, the outer surface of which is fixedly installed with the inner wall of the receiving cavity, and a connecting shaft is rotatably connected inside the support ring, one end of which is fixedly installed with the outer surface of the fixed frame.

[0009] In this technical solution, the rotation of the connecting shaft inside the support ring can control the front and back positions of the fixed frame, making it convenient to switch rotations in winter and summer.

[0010] In the above technical solution, the fixed frame is a rigid frame, and the first mounting frame and the second mounting frame are respectively located at the front and rear positions of the fixed frame.

[0011] In this technical solution, the perforated plate and leather plate can be installed through mounting frame one and mounting frame two, and the rigid structure of the fixed frame improves the stability when the passenger's back is squeezed.

[0012] In the above technical solution, a fixing hole is further provided inside the fixing frame, and the outer surface of the insertion rod is slidably connected to the inside of the fixing hole.

[0013] In this technical solution, the angle of the fixing frame can be fixed when the insertion rod enters the fixing hole. When the fixing frame is parallel to the back, the insertion rod is controlled to enter the fixing hole, and the position of the fixing frame is fixed at this time.

[0014] In the above technical solution, further, the other end of the insertion rod is fixedly installed on the outer surface of the push plate, the outer surface of the insertion rod is slidably connected to the inner wall of the backrest, and the insertion rod is symmetrically arranged inside the fixed box.

[0015] In this technical solution, the movement can be controlled by a push plate. By controlling the movement of the push plate, multiple sets of insert rods can be moved. The fixing box is fixedly installed on both sides of the backrest. The fixing box is made of stainless steel, which increases the stability when the insert rods are fixed.

[0016] In the above technical solution, the fixed frame is further positioned by multiple sets of insert rods, and the insert rods enter the interior of the fixed frame when the fixed frame is parallel to the backrest.

[0017] In this technical solution, the use of multiple sets of insert rods can increase the stability of the fixed frame when it is squeezed by passengers. At this time, both sides of the fixed frame are limited and supported by the insert rods.

[0018] In the above technical solution, both magnetic plate one and magnetic plate two are strong magnets, and a handle is fixedly installed on the outer surface of the push plate.

[0019] In this technical solution, the strong magnetic attraction between magnetic plate one and magnetic plate two can fix the position of the push plate. At this time, the insertion rod will enter the interior of the fixing hole. When switching the front and back of the fixing frame, the push plate can be pulled out directly by the handle.

[0020] The beneficial effects of this utility model are: 1. This new type of bus seat backrest, through the cooperation between the connecting mechanism and the insert rod, can control the rotation of the fixed frame inside the backrest under the action of the connecting mechanism. When the fixed frame is parallel to the backrest, the insert rod can fix the fixed frame. In summer, the control plate is switched to the front, which improves the breathability of the backrest. In winter, the control plate is switched to the front, which makes the backrest more comfortable when it is in contact with the body. This realizes the function of switching between winter and summer for the bus seat backrest, which helps to meet the needs of breathability in summer and comfort in winter.

[0021] 2. The new type of bus seat backrest is equipped with magnetic plate one and magnetic plate two, etc. The strong magnetic attraction between magnetic plate one and magnetic plate two can control the insertion rod to enter the inside of the fixing hole. At this time, the insertion rod can fix the angle of the fixing frame. The vertical arrangement of multiple sets of insertion rods ensures the support stability of the fixing frame when it is squeezed by passengers. Attached Figure Description
