Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to automatic luggage compartment door anti-pinch technical field, concretely relates to an automatic luggage compartment door anti-pinch air bag. BACKGROUND
[0002] The pressure switch and electronic delay anti-pinch mode are adopted in the common passenger car compartment door, the automatic luggage compartment door is heavy due to the self-weight of its body and compartment door outer swing mechanism, and the automatic luggage compartment door moves from top to bottom during the closing process, so that the anti-pinch force is too large due to the too fast movement of the automatic luggage compartment door, or the delay is too long due to the jamming of the movement, and the compartment door cannot be closed, in addition, the anti-pinch contact surface is not buffered and is easy to hurt people, and the like. Therefore, the original pressure switch and electronic delay anti-pinch function are not suitable for the automatic luggage compartment door.
[0003] Therefore, the utility model specially designs and develops an anti-pinch air bag installed at the bottom of the automatic luggage compartment door, designs a new automatic luggage compartment door air bag anti-pinch device based on the anti-pinch air bag, replaces the original automatic luggage compartment door anti-pinch mode, and solves the hidden danger of the original anti-pinch mode. CONTENT OF THE UTILITY MODEL
[0004] The utility model aims at overcoming the defects of the prior art, and provides an automatic luggage compartment door anti-pinch air bag, which has the characteristics of high safety, direct action, sensitive reaction and simple structure through the automatic luggage compartment door anti-pinch function.
[0005] In order to achieve the purpose of the utility model, the utility model adopts the technical scheme that:
[0006] The utility model discloses an automatic luggage compartment door anti-pinch air bag, which comprises an automatic luggage compartment door, a gas pipe, an air bag mounting profile and an air bag rubber strip.
[0007] The automatic luggage compartment door, the air bag mounting profile and the air bag rubber strip are arranged on the same vertical direction through the through hole of the gas pipe.
[0008] The clamping groove of the air bag mounting profile is matched with the air bag rubber strip.
[0009] The two ends of the air bag rubber strip are sealed by gluing.
[0010] The utility model has the advantages of:
[0011] The automatic luggage compartment door is compact in structure, beautiful in appearance, responds directly from a contact surface, and is rapid and sensitive in reaction, and the safety performance of the automatic luggage compartment door is effectively improved. BRIEF DESCRIPTION OF DRAWINGS
[0012] Fig. 1 It is a structural schematic view of the utility model;
[0013] Fig. 2 It is a sectional view of the utility model.
[0014] In the drawing: 1. automatic luggage compartment door, 2. air pipe, 3. air bag mounting profile, 4. air bag rubber strip, 5. air bag front plug, 6. air bag rear plug, 7. air cavity. DETAILED DESCRIPTION
[0015] The utility model is further illustrated below in combination with the drawings and examples:
[0016] Referring to Figs. 1-2 .
[0017] As Fig. 1 shown, the utility model discloses an automatic luggage compartment door anti-pinch air bag, including automatic luggage compartment door 1, air pipe 2, air bag mounting profile 3, air bag rubber strip 4, the bottom of automatic luggage compartment door 1 sets up air bag mounting profile 3, air bag rubber strip 4 installs into the bottom clamping groove of air bag mounting profile 3, the both ends of air bag rubber strip 4 inside air cavity 7 are equipped with air bag front plug 5 and air bag rear plug 6 respectively, one end of air pipe 2 penetrates air bag front plug 5 and places in air cavity 7 inside, the other end of air pipe 2 penetrates automatic luggage compartment door 1 and air bag mounting profile 3 and connects air pressure inductive controller.
[0018] As Fig. 2 shown, automatic luggage compartment door 1, air bag mounting profile 3 and air bag rubber strip 4 are used for being located in the same vertical direction through the hole of air pipe 2.
[0019] The clamping groove of air bag mounting profile 3 is matched with air bag rubber strip 4.
[0020] The both ends of air bag rubber strip 4 are sealed by gluing respectively, so that a stable air pressure is formed in air cavity 7.
[0021] Working principle:
[0022] When automatic luggage compartment door 1 is closed, if encountering an obstacle, air cavity 7 can form an effective buffer layer, and the rapid change of air pressure in air cavity 7 gives electromagnetic valve signal through the air pressure inductive controller connected by air pipe, and electromagnetic valve changes direction to prevent the compartment door from continuing to close, preventing passengers from being pinched or articles from being damaged.
[0023] The above merely describes preferred embodiments of the present application, and is not intended to limit the present application in other forms, and any skilled person in the art can modify or change the above disclosed technical content to equivalent embodiments with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiments without departing from the technical solution of the present application, and in accordance with the technical essence of the present application, still belong to the protection scope of the technical solution of the present application.
