Problems solved by technology

In the drop detection project of the baby carriage, the three wheels of the children's tricycle are required to touch the ground at the same time. Traditional testing methods are difficult to achieve this function, which affects the accuracy of the test results and makes the drop detection of the children's tricycle flawed.

Embodiment 1

[0016] see figure 1 and figure 2 , the baby carriage drop performance testing machine includes a bottom frame (11), a front wheel disengagement mechanism, a rear wheel disengagement mechanism, a baby carriage front wheel support plate (7), a baby carriage rear wheel support plate (8), and is characterized in that: the bottom frame (11 ) right end is connected with a right vertical aluminum profile (1), and the left end of the bottom frame (11) is connected with a left vertical aluminum profile (2) through a screw and a nut; the right vertical aluminum profile (1) and the left The middle part of the vertical aluminum profile (2) is respectively connected with the rear wheel disengagement mechanism and the front wheel disengagement mechanism through the right horizontal aluminum profile (10) and the left horizontal aluminum profile (3); the front wheel disengagement mechanism and the rear wheel disengagement mechanism The mechanism is connected with the baby carriage front whe...

Embodiment 2

[0018] The structure of the bottom frame (11) is: the upper surface is equipped with two linear guide rails (17, 18), and the guide rails (17, 18) are equipped with guide rail mounting plates (16, 20), and the guide rail mounting plates (16, 18) 20) are connected by an auxiliary beam (25). The hand wheel (5) drives the lead screw nut (24) through the lead screw (6), and the lead screw nut (24) is connected with the left horizontal aluminum profile (3) through the auxiliary beam (25). The rotating hand wheel (5) is transmitted to the driven screw nut (24) by the leading screw (6) to realize that the guide rail mounting plate (16, 20) moves along the direction of the linear guide rail (17, 18), and the moving distance is selected according to the size of the vehicle body.

[0019] The structures of the front wheel disengagement mechanism and the rear wheel disengagement mechanism are as follows: the front wheel disengagement mechanism is composed of a left cylinder (4) and a lef...

Abstract

The invention relates to a testing machine for detecting child tricycle falling performance. The testing machine comprises a bottom portion framework, a front wheel disengaging mechanism, a back wheel disengaging mechanism, a child tricycle front wheel supporting plate, and a child tricycle back wheel supporting plate, wherein the right end of the bottom portion framework is connected with a right vertical aluminum section and the left end of the bottom portion framework is connected with a left vertical aluminum section through a lead screw and a nut. The middle portion of the right vertical aluminum section and the middle portion of the left vertical aluminum section are respectively connected with the back wheel disengaging mechanism and the front wheel disengaging mechanism through a right horizontal aluminum section and left horizontal aluminum section. The front wheel disengaging mechanism and the back wheel disengaging mechanism are connected with the child tricycle front wheel supporting plate and the child tricycle back wheel supporting plate. During a testing process, the child tricycle front wheel supporting plate and the child tricycle back supporting plate are stretched out through the movement of the front wheel disengaging mechanism and the back wheel disengaging mechanism, a cart is placed on the supporting plates which are stretched out, then a supporting plate of a front wheel and supporting plates of back wheels retract backwards at the same time, and due to the fact that the front wheel of a child tricycle and the back wheels of a baby tricycle are not supported, the three wheels fall onto the ground under the action of gravity, so that a once dropping test is achieved.

Description

technical field [0001] The invention relates to a new type of baby carriage drop performance testing machine, which is characterized in that it can carry out the children's tricycle anti-drop performance test according to various standards such as ASTM, EN, GB, ISO, etc., and can place the tested children's tricycle in a certain position according to the requirements of the standard. Height and implement the drop performance test to detect the degree of damage after the children's tricycle falls. The device belongs to the technical field of baby carriage safety performance testing. technical background [0002] In recent years, as people have higher and higher requirements for the quality of stroller products, the performance testing of the quality of stroller products is particularly important. The drop test involved in the present invention can detect the overall performance of the stroller and the structural strength and deformation of parts when dropped, and belongs to ...
