Description

Technical Field

[0001] The utility model relates to the technical field of automobile seat ventilation measurement, and more specifically, to a device for measuring the ventilation volume of an automobile seat. Background Technique

[0002] In recent years, with the rapid development of the automobile industry, users' requirements for the comfort of automobiles have become increasingly high; automobile seats are important facilities in the passenger compartment of automobiles, and the seat ventilation function is an important comfort configuration. When the temperature in the carriage is relatively high, seat ventilation accelerates the air flow of the seat cushion and backrest, reduces the temperature of the parts where the body contacts the seat, and alleviates the sultriness and discomfort of the back and legs caused by the poor air permeability of the seat cover itself. Therefore, in order to ensure the comfort of the seat, before the vehicle leaves the factory, each automobile manufacturer needs to test the ventilation function of the seat.

[0003] After retrieval, a new type of device for measuring the ventilation volume of an automobile seat is disclosed in a Chinese patent with the publication number CN 213180190 U, which includes a seat slide saddle, a test box, a gas mass flowmeter, a pressure difference sensor, a fan, and a controller; the seat slide saddle is fixedly connected to one end of the test box; the test box has a hollow structure inside, and the end of the test box connected to the seat slide saddle is an open structure, so that the inside of the test box is communicated with the seat slide saddle. A pressure difference sensor is installed inside the test box, and the pressure difference sensor is electrically connected to the controller for transmitting pressure difference information to the controller. The end of the test box is processed with a ventilation port, and the ventilation port is connected to the fan through a ventilation pipeline. A gas mass flowmeter is installed on the ventilation pipeline, and the gas mass flowmeter is electrically connected to the controller for measuring the mass of the gas passing through the ventilation pipeline; the fan is electrically connected to the controller, and the controller controls the fan to supply air to the test box or extract air from the test box. The structure of this measurement device is reasonably designed and can achieve high-precision full-automatic measurement.

[0004] After research by the inventor, it is found that there is a lack of sealing measures in the connection between the seat slide saddle and the test box in the above technology. When measuring the ventilation volume, it is easy for gas to leak from the connection, resulting in inaccurate measured ventilation volume and affecting the test accuracy. Therefore, the utility model proposes a device for measuring the ventilation volume of an automobile seat. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a device for measuring the ventilation volume of an automobile seat, which can solve the problems raised in the above background technique.

[0006] The embodiments of the utility model are implemented as follows:

[0007] An automobile seat ventilation volume measuring device includes a measuring box and a seat slide saddle. Universal wheels are rotatably connected to the four corners of the bottom of the measuring box and the seat slide saddle. A sealing assembly is arranged on one side of the measuring box. The sealing assembly includes a sealing box fixedly connected to the left side of the measuring box. Compression springs are evenly and fixedly connected to the right side of the inner cavity of the sealing box. The other ends of the compression springs are fixedly connected to a connecting plate.

An inner sealing ring is fixedly connected to the inner side edge of the return-shaped frame. A sealing pad is fixedly connected to the side of the return-shaped frame located outside the sealing box.

[0008] As a further preference of this technical solution, the connecting plate is slidably connected to the inside of the sealing box, and the outer side wall of the connecting plate is attached to the inner side wall of the sealing box.

[0009] As a further preference of this technical solution, a fan is fixedly connected to the top of the measuring box. A ventilation pipeline is fixedly connected to the output end of the fan. A gas mass flowmeter is fixedly connected to the outer side wall of the ventilation pipeline.

[0010] As a further preference of this technical solution, the input end of the fan is electrically connected to the output end of an external power source. The outlet end of the ventilation pipeline penetrates and extends to the right side of the inner cavity of the measuring box.

[0011] As a further preference of this technical solution, rotating seats are fixedly connected to the upper and lower parts of the front and rear sides of the sealing box. A connecting seat is rotatably connected to the inside of the rotating seat through a pin shaft. A sleeve is fixedly connected to the left side of the connecting seat. A connecting spring is fixedly connected to the middle of the right side of the inner cavity of the sleeve. The other end of the connecting spring is fixedly connected to a circular plate.

[0012] As a further preference of this technical solution, the circular plate is slidably connected to the inner cavity of the sleeve, and the outer side wall of the circular plate is attached to the inner side wall of the sleeve.

[0013] As a further preference of this technical solution, the threaded rod penetrates through the middle of the left side of the sleeve and is slidably connected to the sleeve. Anti-slip lines are arranged on the outer side wall of the knob.

[0014] The beneficial effects of the present utility model are:

[0015] Through the provided sealing assembly, when connecting the seat saddle and the measuring box, one side of the seat saddle contacts the sealing gasket, squeezing the seat saddle, causing the loop frame to move, enabling the outer sealing ring and the inner sealing ring to contact the sealing box, and at the same time causing the connecting plate to move, squeezing the compression spring. Through the reaction force of the compression spring, the sealing gasket is closely attached to one side of the seat saddle, thereby improving the sealing performance at the connection, ensuring the seal during ventilation, avoiding leakage during ventilation, preventing inaccurate measurement, and thus improving the measurement accuracy;

[0016] Through the provided connecting spring, round plate, threaded rod, and knob, by deflecting the sleeve, the threaded rod is located inside the notch. Rotate the knob, causing the knob to move outside the threaded rod. When the knob fits against the baffle, continue to rotate the knob, causing the threaded rod to gradually move out of the sleeve, driving the round plate to move, stretching the connecting spring. Through the reaction force of the connecting spring, the knob presses tightly against the baffle, causing the seat saddle to tightly press against the sealing assembly, thereby further ensuring the sealing performance of the connection, improving the practicality of the device, and facilitating the connection between the seat saddle and the measuring box.
