Description

Technical Field

[0001] The utility model relates to the field of seat size measurement, in particular to a tooling for measuring the internal size of a child seat. Background Art

[0002] The child seat is installed in a car for children to use, and at the same time replaces the seat belt of the car itself to protect the safety of children in case of an emergency brake of the car. Different from ordinary car seats, in order to improve safety and the comfort of children when sitting, baffles are usually provided on both left and right sides of the current child seat, and the shape of the child seat conforms to the ergonomics of children, so that the child seat wraps the child in a semi-surrounding shape when the child uses it. Therefore, when designing and producing, it is necessary to measure parameters such as the size inside the child seat and the angle between the backrest and the base to check whether the sizes of the child seat meet the requirements. However, the shape of the child seat is complex, making it difficult for tools such as straight rulers, tape measures, and flexible rulers for measuring length to accurately fit the inner wall of the child seat, resulting in large measurement errors in size and angle.

[0003] At present, although there is a measurement tool for the installation deflection angle of a child safety seat as disclosed in the patent application with the application number CN202221128135.2, which sets a measurement connecting plate and an adjustment positioning mechanism; the adjustment positioning mechanism can be detachably arranged on the measurement connecting plate and can be clamped on the side wing of the child safety seat; the adjustment positioning mechanism can adjust the clamping width to match the width of the side wing of the child safety seat; a measurement surface is provided on the measurement connecting plate, and the measurement surface can be used to install a protractor, and the protractor can measure the deflection angle of the child safety seat during installation. However, this measurement tool lacks the measurement of the width of positions such as the shoulders and thighs of the child seat, so there is still a problem that it is difficult to accurately measure the internal space size of the child seat. Summary of the Utility Model

[0004] The utility model aims to provide a tooling for measuring the internal size of a child seat to solve the problem that it is difficult to accurately measure the size due to the complex internal shape of the child seat.

[0005] To achieve the above object, the utility model adopts the following technical scheme: A tooling for measuring the internal size of a child seat includes a torso assembly, on which a shoulder simulation unit and a thigh simulation unit are provided. The shoulder simulation unit includes a longitudinal sliding rod and two shoulder measurement components. The longitudinal sliding rod is slidably matched with the torso assembly in the height direction, and both of the two shoulder measurement components are slidably matched with the longitudinal sliding rod in the width direction of the seat. The thigh simulation unit includes a transverse sliding rod and two thigh measurement components. The transverse sliding rod is slidably matched with the torso assembly in the depth direction of the seat, and both of the two thigh measurement components are slidably matched with the transverse sliding rod in the width direction of the seat.

[0006] The beneficial effect of this scheme is:

[0007] 1. When measuring, there are two measuring methods for the measuring tooling of this solution. Taking the measurement of the shoulder width as an example, in one method, the two shoulder measuring components are slid in the direction away from each other and respectively abutted against the baffles on both sides of the child seat, and the longitudinal sliding rod guides the sliding of the shoulder measuring components to ensure that the abutting positions of the shoulder measuring components against the baffles on both sides of the child seat are symmetrical. At this time, measuring the two abutting positions can directly measure the width of the shoulder position of the child seat.

[0008] The second method is: Denote the connection position of the shoulder measuring component and the longitudinal sliding rod as point A, and the abutting position of the shoulder measuring component against the child seat as point B. Since the structure of the shoulder measuring component does not change during measurement, the length S of points A and B along the width direction of the child seat AB remains unchanged. Therefore, after measuring the length between the two shoulder measuring components along the axial direction of the longitudinal sliding rod, adding twice S AB is the width of the shoulder position of the child seat. Compared with the first measuring method, in the second measuring method, since the longitudinal sliding rod is a rigid rod-shaped structure, it can provide support for the measuring ruler during the measurement process, and the measuring ruler will not be skewed when measuring along the longitudinal sliding rod, so the measurement is more accurate. And the length of S AB is a determined constant and does not need to be measured on site. Therefore, even the simplest measuring tools such as a tape measure or a flexible ruler can be used for accurate measurement.

[0009] 2. The torso assembly in this solution can be placed inside the child seat and support the shoulder simulation unit and the thigh simulation unit during testing. The measurer only needs to adjust the positions of the shoulder measuring component and the thigh measuring component and measure the relevant dimensions, without having to hold the measuring tooling throughout the measurement process, effectively improving the convenience of measurement.

[0010] 3. The longitudinal sliding rod in this solution can be adjusted along the height direction of the child seat backrest. When measuring the shoulder position width of child seats of different sizes, sliding the longitudinal sliding rod can quickly slide the shoulder measuring component to the shoulder position of the child seat to be measured, so as to accurately measure the shoulder position.

[0011] Furthermore, the shoulder measuring component includes a shoulder measuring rod and a shoulder measuring block. The shoulder measuring rod is slidably matched with the shoulder sliding rod; the shoulder measuring block is arranged at one end of the shoulder measuring rod away from the shoulder sliding rod, and any one shoulder measuring block protrudes towards the side away from the other shoulder measuring block.

[0012] The beneficial effects of this solution are as follows: Since the shoulder measuring block protrudes outward, the shoulder measuring block can abut against the baffles on both sides of the child seat prior to the rod-shaped shoulder sliding rod. When the baffles on both sides of the child seat also have an ergonomic arc design, the protrusion of the shoulder measuring block ensures that it can abut against the baffle, so that the measurement can still be carried out.

[0013] Furthermore, the shoulder measuring block is slidably engaged with the shoulder measuring rod along the depth direction of the seat.

[0014] The beneficial effects of this solution are as follows: When measuring, the position of the shoulder measuring block can be adjusted finely along the depth direction of the child seat, so as to further accurately measure the width of the shoulder position.

[0015] Furthermore, scale markings are provided on the shoulder sliding rod.

[0016] The beneficial effects of this solution are as follows: The width of the shoulder position can be quickly determined without additional measuring tools, further improving the measurement efficiency of the width of the shoulder position.

[0017] Furthermore, the thigh measuring assembly includes a thigh measuring rod and a thigh measuring block. The thigh measuring rod is slidably engaged with the transverse sliding rod. The thigh measuring block is provided at one end of the thigh measuring rod away from the transverse sliding rod. Any one of the thigh measuring blocks protrudes toward the side away from the other thigh measuring block.

[0018] The beneficial effects of this solution are as follows: Similar to the shoulder measuring block, the protrusion of the thigh measuring block in this solution can also ensure that it is in contact with the baffle when the baffle has an arc, so as to accurately measure the width of the thigh position.

[0019] Furthermore, scale markings are provided on the transverse sliding rod.

[0020] The beneficial effects of this solution are as follows: The measurement efficiency of the width of the thigh position can be improved through the scale indication.

[0021] Furthermore, the trunk assembly includes a main bracket and a guide bracket. The guide bracket is provided on the main bracket. The shoulder measuring assembly is slidably engaged with the guide bracket.

[0022] The beneficial effects of this solution are as follows: When measuring, the main bracket is placed on the child seat. There is a space for conveniently sliding the shoulder measuring assembly between the shoulder measuring assembly and the main bracket in this solution, making the measurement more convenient.

[0023] Furthermore, the main bracket includes a cross bar and a longitudinal bar. The cross bar and the longitudinal bar are hinged, and an angle measuring device is provided between the cross bar and the longitudinal bar.

[0024] The beneficial effects of this solution are as follows: After the main bracket is placed on the child seat, the cross bar is located on the seat cushion of the child seat, and the longitudinal bar is attached to the backrest of the child seat. The seat cushion and the backrest support the main bracket from multiple directions simultaneously. Therefore, the main bracket in this solution is not easily toppled.

[0030] Embodiment 1

[0031] Embodiment 1 is basically as shown in the Figure 1 accompanying drawings. The inner dimension measuring tool for the child seat includes a torso assembly, a shoulder simulation unit, and a thigh simulation unit. The torso assembly includes a main bracket 1 and a guide frame 2. The main bracket 1 includes a longitudinal bar 12 and a cross bar 11. The longitudinal bar 12 is vertically arranged. The guide frame 2 is L-shaped and is installed on the longitudinal bar 12 by bolts. The cross bar 11 is arranged along the depth direction of the child seat and is hinged to the lower end of the longitudinal bar 12. An angle measuring device is provided between the lower end of the longitudinal bar 12 and the cross bar 11. The angle measuring device in this embodiment adopts an existing digital display angle gauge, and the rotation center of the cross bar 11 and the longitudinal bar 12 is coaxial with the rotation center of the digital display angle gauge. Specifically, the structure, installation method, and usage method of the digital display angle gauge are the same as those in the prior art, and will not be elaborated in this embodiment.

[0032] The shoulder simulation unit is higher than the thigh simulation unit. The shoulder simulation unit includes a longitudinal sliding rod 3 and two shoulder measurement assemblies 4. A first sliding seat 21 is sleeved on the vertical part of the guide frame 2. The vertical part of the guide frame 2 in this embodiment is a slide rail. The cross section of the first sliding seat 21 is rectangular, and the first sliding seat 21 is slidably matched with the vertical part of the guide frame 2. The longitudinal sliding rod 3 includes two parts, front and back. The two parts are coaxial and are respectively welded to the front and back side walls of the first sliding seat 21.

[0033] Two shoulder measurement components 4 are respectively opposite to two parts of the longitudinal sliding rod 3 and are symmetrically designed along the guide frame 2. In this embodiment, the rear shoulder measurement component 4 is taken as an example: the longitudinal sliding rod 3 is also a slide rail. A rectangular second sliding seat 31 is slidably arranged at the rear part of the longitudinal sliding rod 3. Positioning bolts are in threaded fit with both the first sliding seat 21 and the second sliding seat 31. The positioning bolt on the first sliding seat 21 can abut against the guide frame 2 to position the first sliding seat 21; the positioning bolt on the second sliding seat 31 can abut against the longitudinal sliding rod 3 to position the second sliding seat 31.

[0034] The shoulder measurement component 4 includes a shoulder measurement rod 41 and a shoulder measurement block 42. The shoulder measurement rod 41 is parallel to the cross bar 11, and the front end of the shoulder measurement rod 41 is installed on the second sliding seat 31 through a bolt. The shoulder measurement rod 41 in this embodiment is also a slide rail. The shoulder measurement block 42 is located at the right end of the shoulder measurement rod 41. The right end of the shoulder measurement rod 41 penetrates through the shoulder measurement block 42, and the shoulder measurement block 42 is in sliding fit with the shoulder measurement rod 41. As shown in Figure 2 the figure, the rear side wall of the shoulder measurement block 42 is an arc surface protruding to the rear side of the shoulder measurement rod 41.

[0035] The thigh simulation unit includes a transverse sliding rod 6 and two thigh measurement components 5. The transverse sliding rod 6 is perpendicular to the cross bar 11 and is in sliding fit with the cross bar 11. Specifically, the structure of the transverse sliding rod 6 and the connection mode between the transverse sliding rod 6 and the cross bar 11 in this embodiment are the same as those of the longitudinal sliding rod 3, and positioning bolts are also used for positioning. The two thigh measurement components 5 are respectively located on the front and rear sides of the cross bar 11 and are symmetrically arranged along the cross bar 11. The thigh measurement component 5 includes a thigh measurement rod 51 and a thigh measurement block 52. The connection mode between the thigh measurement rod 51 and the transverse sliding rod 6 in this embodiment is the same as the connection mode between the shoulder measurement rod 41 and the longitudinal sliding rod 3, and positioning bolts are also used for positioning. The thigh measurement block 52 is installed at the right end of the thigh measurement rod 51 through a bolt, and each thigh measurement block 52 also protrudes to the side away from the cross bar 11 to the side of the thigh measurement rod 51 away from the cross bar 11.

[0036] The specific implementation process is as follows:

[0037] When measuring the width of the shoulder position and thigh position of a child seat, first place the measuring tooling in this embodiment on the child seat, and make the longitudinal sliding rod 3 and the transverse sliding rod 6 located on the left side of the child seat. At this time, the cross bar 11 falls on the seat cushion of the child seat, and the longitudinal rod 12 is in contact with the backrest of the child seat. At this time, measure the included angle between the seat cushion and the backrest of the child seat through the angle measuring device. Then loosen the positioning bolt, slide the first sliding seat 21 along the guide frame 2, adjust the position of the shoulder measuring assembly 4 to ensure that the shoulder measuring block 42 is directly opposite the shoulder position of the child seat, and finally tighten the positioning bolt on the first sliding seat 21 to position the first sliding seat 21 so that the longitudinal sliding rod 3 will not slide down.

[0038] Slide the shoulder measuring rods 41 in the direction away from each other until the two shoulder measuring blocks 42 are respectively abutted against the baffles on the front and rear sides of the child seat. Tighten the positioning bolt on the second sliding seat 31, and measure the length between the positions where the two shoulder measuring blocks 42 are abutted against the baffle through the measuring ruler, which is the width of the shoulder position of the child seat.

[0039] Similarly, slide the thigh measuring rod 51 so that the thigh measuring block 52 is abutted against the baffles on both sides of the child seat, and then measure the length between the positions where the two thigh measuring blocks 52 are abutted against the baffle through the measuring ruler, which is the width of the thigh position of the child seat.

[0040] After the measurement is completed, loosen the positioning bolt, slide the thigh measuring rod 51 and the shoulder measuring rod 41 in the reverse direction, and then the tooling can be taken out of the child seat.

[0041] Embodiment 2

[0042] On the basis of Embodiment 1, as Figure 3 shown, a number of scale marks 32 are provided axially on both parts of the shoulder sliding rod and both parts of the transverse sliding rod 6 in this embodiment. Taking one longitudinal sliding rod 3 as an example, the scale marks 32 on this longitudinal sliding rod 3 can be marked in such a way that the zero scale line is located at the center of the guide frame 2 and the scale marks 32 increase gradually from top to bottom.

[0043] In actual implementation, the connection position between the shoulder measuring assembly 4 and the longitudinal sliding rod 3 can also be recorded as point A, and the position where the shoulder measuring assembly 4 abuts against the child seat can be recorded as point B. The distance S AB between the positions of points A and B projected on the longitudinal sliding rod 3, and the distance between any point on the longitudinal sliding rod 3 and the center of the guide frame 2 is S1. When determining the scale marks 32, first measure S AB and S1, then the number of the scale marks 32 at any point is S AB+S1. When the scale mark 32 is marked by this method, the width of the lower part of the child seat can be directly measured by reading. At this time, the readings on the lower longitudinal sliding rod 3 and the upper longitudinal sliding rod 3 are added together to directly determine the shoulder width of the child seat, without the need to use additional measuring tools.

[0044] The above are only embodiments of the present invention. Specific technical solutions and / or common knowledge such as characteristics well known in the art are not described in detail herein. It should be noted that for those skilled in the art, without departing from the technical solution of the present invention, several deformations and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the patent. The protection scope required by this application should be based on the content of its claims, and the specific implementation manners described in the specification can be used to explain the content of the claims.
