Description

Technical Field

[0001] The utility model relates to the technical field of pneumatic lumbar support, in particular to a pump head shell and a pump-valve integrated machine for a lumbar support. Background Art

[0002] With the increase in personal and family income, cars have become the first choice for family consumption. In order to reduce the fatigue caused by long-term driving, it is often necessary to add a support at the waist position in the car seat to improve the comfort of the driver or passenger. The common lumbar support built into the seat can be divided into mechanical and pneumatic types according to the different supports. The mechanical lumbar support is relatively large in size and weight, and the customer experience is poor. In addition, when the vehicle collides, it will also cause personal injury to the passengers, so the pneumatic lumbar support is gradually replacing the mechanical lumbar support.

[0003] The air pump and air valve used in traditional pneumatic lumbar supports are separate types. Due to many disadvantages, they were quickly eliminated. Now the air pump and air valve used in pneumatic lumbar supports are all integrated pump-valve structures, including a pump head housing, a solenoid valve and an air pump. The solenoid valve is located inside the pump head housing, and then the pump head housing is snap-connected to the air pump. However, the existing pump head shell is a plastic part, which is prone to damage due to weak structural strength during plugging and unplugging. For example, the air pipe joint accommodating tube and the connector joint accommodating tube on the pump head shell are both protruding structures, and generally have no reinforcement structure. For example, patent CN110030175A-Pump-valve integrated machine for pneumatic lumbar support for automobile seat, wherein the corresponding air pipe joint accommodating tube and the connector joint accommodating tube on the shell have no reinforcement structure; another example is patent CN114837918 A-Quick-assembly type pneumatic lumbar support pump-valve integrated machine and assembly method, wherein a notch is provided on the cylindrical socket of the air pipe quick-connect connector for accommodating the electromagnetic valve on the head end cover to facilitate checking the air pipe plug-in status, and the notch provided is a through structure, which results in low strength of the cylindrical socket and is easily damaged by external forces.
