Description

Technical Field

[0001] This invention relates to the field of product performance testing technology, and in particular to a buckle release force testing device and testing method. Background Technology

[0002] As a key component of a safety system, the buckle's core function is to ensure the seatbelt is reliably secured, thereby effectively protecting the user from injury in emergencies. This safety component is particularly important in the field of strollers, as its performance directly affects the safety of infants and toddlers while riding in a stroller. During the use of a stroller, it is essential to ensure that the buckle can withstand a specific load of pressure when not released, to prevent accidental release due to the child struggling or sudden braking of the stroller.

[0003] According to current industry standards, hook and loop fasteners must undergo rigorous release force testing before leaving the factory to verify that they can only be released within a specified range of pressure. This test is crucial for balancing safety and ease of use: ensuring smooth release in an emergency while preventing children from unfastening them themselves. However, existing testing equipment generally has functional limitations, with most only compatible with one type of hook and loop fastener, either a double-acting or single-acting release design. This specialization leads to low utilization of the testing equipment, increasing testing costs and reducing overall testing efficiency.

[0004] Therefore, there is an urgent need for a device and method for testing the release force of hooks and loops to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a hook and loop release force testing device and method, which can adapt to the testing needs of different structural types of hooks while ensuring the accuracy of the test results, thus expanding the versatility, helping to reduce the cost of hook and loop testing, and improving the efficiency of hook and loop testing.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] On the one hand, a device for testing the release force of a hook and loop is provided, comprising:

[0008] support;

[0009] A support base is movably mounted on the bracket in the vertical direction for horizontally supporting the buckle;

[0010] Multiple sets of balancing components are spaced around the support and are movably mounted on the bracket along the circumference of the support. The balancing components include counterweights and balancing belts. One end of the balancing belt can extend horizontally and be connected with a buckle, and the other end of the balancing belt can extend vertically and be connected with the counterweights.

[0011] The release assembly includes a housing and a release member, the release member being movably disposed in the housing and configured to apply a release force to the latch.

[0012] Optionally, the buckle release force testing device also includes a connecting strap, one end of which can be connected to the bracket and the other end of which can be connected to the buckle. The connecting strap extends horizontally and is arranged at an angle to the balance belt, and the height of the end of the balance belt connected to the buckle is the same as the height of the connecting strap.

[0013] Optionally, the buckle release force testing device also includes a clamping assembly disposed on the bracket for clamping the end of the connecting strap away from the buckle to the bracket.

[0014] Optionally, the clamping assembly includes a clamping seat and a clamping member. The clamping seat is disposed on the bracket, and the clamping member is movably disposed above the clamping seat in a vertical direction. The end of the connecting strap away from the buckle is located between the clamping seat and the clamping member, driving the clamping member to move. The clamping member can contact the connecting strap and press the connecting strap against the clamping seat.

[0015] Optionally, the balancing assembly also includes a movable seat and a steering component disposed on the movable seat. The movable seat is movably disposed on the support along the circumference of the support seat. The steering component is provided with an arc-shaped surface that transitions from the horizontal direction to the vertical direction. The balancing belt can at least partially conform to the arc-shaped surface.

[0016] Optionally, the bracket is provided with a groove extending circumferentially along the support seat, and the movable seat is provided with a slider, which is embedded in the groove and slides in cooperation with the groove.

[0017] Optionally, the release assembly also includes a detection element disposed in the housing and connected to the release element, for detecting the release force applied by the release element to the latch.

[0018] Optionally, the counterweights include multiple counterweights of different weights, and the balance belt can be connected to one of the multiple counterweights.

[0019] Optionally, the buckle release force testing device also includes a linear drive unit mounted on the bracket, the output end of which is connected to the support seat to drive the support seat to move vertically.

[0020] On the other hand, a method for testing the release force of a hook and loop is provided, which uses the above-mentioned hook and loop release force testing device to test the release force required to release the hook and loop. The hook and loop with the double action release structure includes two release parts.

[0021] The method for testing the release force of a hook and loop includes the following steps:

[0022] S1. Place the buckle on the support and connect the balance belt to the buckle and the counterweight;

[0023] S2. Determine whether the end of the balance belt connected to the buckle extends horizontally. If yes, proceed to step S3. If no, drive the support to move vertically until the end of the balance belt connected to the buckle extends horizontally.

[0024] S3. Determine whether the end of the balance component connected to the buckle extends along the release direction of the buckle. If yes, proceed to step S4. If no, drive the balance component to move until the end of the balance component connected to the buckle extends along the release direction of the buckle.

[0025] S4. Determine the structure of the clasp:

[0026] If the latch is a single-action release mechanism, the release element is driven to move to contact the latch and apply a release force to the latch until the latch is released;

[0027] If the latch is a double-action release structure, then proceed with steps S41 to S44;

[0028] S41. Release a release unit;

[0029] S42. Drive the release member to move to contact the unreleased release part, and apply a release force to the unreleased release part until the unreleased release part is released;

[0030] S43. Place the buckle back on the support and connect the buckle to the multiple balance belts;

[0031] S44. Release the release part released in step S43, and repeat step S42.

[0032] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0033] This invention provides a hook and loop release force testing device and method. The hook and loop can be placed horizontally on a support. By adjusting the vertical position of the support, when hooks of different thicknesses are connected to a balance belt, one end of the balance belt can always maintain a horizontal extension during the test. This effectively avoids tilting or deformation of the hook and loop during the test, helps eliminate interference from lateral separation forces on the test results, and ensures that the release component applies only the necessary release force to the hook and loop, thus improving the accuracy of the test results. In actual use, hooks and loops are usually in a pre-tightened state, meaning they are subjected to a certain amount of lateral tension. The hook and loop release force testing device provided by this invention connects the other end of the balance belt to a counterweight, accurately replicating the stress environment of the hook and loop during operation, thereby further improving the reliability of the test data. Furthermore, by adjusting the position of the balance component on the support, hooks of different structural types can be subjected to symmetrical forces when connected to multiple balance belts, adapting to the testing needs of hooks of different structural types. This significantly expands the versatility of the hook and loop release force testing device, helps reduce the cost of hook and loop testing, and improves the efficiency of hook and loop testing.

[0047] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0048] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly.

[0051] Example 1

[0052] like Figures 1 to 3 As shown, this embodiment provides a hook and loop release force testing device. While ensuring the accuracy of the test results, it can adapt to the testing needs of hook and loop 100 with different structural types, expand its versatility, help reduce the cost of hook and loop 100 testing, and improve the efficiency of hook and loop 100 testing.

[0053] See Figure 1 and Figure 2 The hook and loop release force testing device includes a bracket 1, a support 2, a release component 4, and multiple sets of balancing components 3. The support 2 is movably mounted on the bracket 1 in the vertical direction to horizontally support the hook and loop 100. Multiple sets of balancing components 3 are spaced around the support 2 and are movably mounted on the bracket 1 in the circumferential direction of the support 2. Each balancing component 3 includes a counterweight 31 and a balancing belt 32. One end of the balancing belt 32 can extend in the horizontal direction and connect to the hook and loop 100, and the other end of the balancing belt 32 can extend in the vertical direction and connect to the counterweight 31. The release component 4 includes a housing 41 and a release element 42. The release element 42 is movably mounted on the housing 41 and is configured to apply a release force to the hook and loop 100.

[0054] The hook and loop release force testing device provided in this embodiment allows the hook and loop 100 to be placed horizontally on the support 2. By adjusting the vertical position of the support 2, hooks and loops of different thicknesses can be connected to the balance belt 32. During the test, one end of the balance belt 32 remains horizontally extended, effectively preventing the hook and loop 100 from tilting or deforming during testing. This helps eliminate interference from lateral separation forces on the test results, ensuring that the release element 42 applies only the necessary release force to the hook and loop 100, thus improving the accuracy of the test results. In actual use, the hook and loop 100 is usually in a pre-tightened state, meaning it experiences a certain amount of lateral tension. The hook and loop release force testing device provided in this embodiment connects the other end of the balance belt 32 to the counterweight 31, accurately replicating the stress environment of the hook and loop 100 during operation, thereby further improving the reliability of the test data. Furthermore, by adjusting the position of the balancing component 3 on the bracket 1, the buckles 100 of different structural types can be subjected to symmetrical forces after being connected to multiple balancing belts 32, so as to adapt to the testing requirements of buckles 100 of different structural types, significantly expanding the versatility of the buckle release force testing device, helping to reduce the cost of buckle 100 testing and improve the efficiency of buckle 100 testing.

[0055] For example, see Figure 3 The balancing component 3 is provided in two sets, and the support seat 2 adopts a disc.

[0056] In this embodiment, see Figure 1 When the latch 100 is a single-action release structure, such as a five-point latch 100, the release part 101 of the latch 100 is located on its upper surface. In this case, the movement direction of the release member 42 is vertical. When the latch 100 is a double-action release structure, such as a two-sided press-type latch 100, the release part 101 of the latch 100 is located on both sides along its width direction. In this case, the movement direction of the release member 42 is horizontal.

[0057] Optionally, see Figure 1 and Figure 3The buckle release force testing device also includes a connecting strap 5. One end of the connecting strap 5 can be connected to the bracket 1, and the other end can be connected to the buckle 100. The connecting strap 5 extends horizontally and is arranged at an angle to the balance belt 32, and the height of the end of the balance belt 32 connected to the buckle 100 is the same as the height of the connecting strap 5. The connecting strap 5 can cooperate with the balance belt 32 so that the buckle 100 can be subjected to a uniform and symmetrical lateral tensile force along its circumference. This not only ensures the stability of the buckle 100 during the test, but also helps to further eliminate the interference of lateral separation force on the test results, thus improving the accuracy of the test results. Especially for buckles 100 with a circular cross-sectional shape, such as the five-point buckle 100 used on strollers, this setting can also prevent the buckle 100 from rotating along its circumference during the test, further improving the reliability of the test data.

[0058] In this embodiment, see Figure 1 and Figure 2 The buckle release force testing device also includes a clamping component 6, which is disposed on the bracket 1 and is used to clamp the end of the connecting strap 5 away from the buckle 100 to the bracket 1 so that the connecting strap 5 can be stably installed on the bracket 1 and ensure that the height of the end of the balance belt 32 connected to the buckle 100 is the same as the height of the connecting strap 5.

[0059] Specifically, see Figure 1 The clamping assembly 6 includes a clamping seat 61 and a clamping member 62. The clamping seat 61 is disposed on the bracket 1, and the clamping member 62 is movably disposed above the clamping seat 61 in a vertical direction. The end of the connecting strap 5 away from the buckle 100 is located between the clamping seat 61 and the clamping member 62. Driving the clamping member 62 to move allows it to contact the connecting strap 5 and press the connecting strap 5 against the clamping seat 61, thus clamping the connecting strap 5 onto the bracket 1. Furthermore, by driving the clamping member 62 to move away from the clamping seat 61, the clamping member 62 can be moved away from the connecting strap 5 to relax the clamping effect of the clamping member 62 on the connecting strap 5, so that the connecting strap 5 can be removed from the bracket 1 when it is no longer needed.

[0060] See Figure 1 and Figure 3 The clamping assembly 6 also includes a connector 63, which includes a screw portion and a clamping portion disposed at one end of the screw portion. The screw portion passes through the clamping member 62 in a vertical direction and is threadedly connected to the clamping seat 61. The clamping portion contacts the side of the clamping member 62 away from the clamping seat 61. By screwing the connector 63, the screw portion moves vertically and drives the clamping portion to push the clamping member 62 to move vertically.

[0061] For example, the connector 63 is a bolt, with the threaded part being the shank of the bolt and the clamping part being the head of the bolt.

[0062] See Figure 3There are two connectors 63, which are symmetrically arranged about the connecting belt 5 to ensure the uniformity of the clamping force of the clamping member 62 on the connecting belt 5.

[0063] Optionally, see Figure 1 The balancing assembly 3 also includes a movable seat 33 and a steering member 34 disposed on the movable seat 33. The movable seat 33 is movably disposed on the bracket 1 along the circumference of the support seat 2. The steering member 34 is provided with an arc-shaped curved surface, which transitions from the horizontal direction to the vertical direction. The balancing belt 32 can at least partially conform to the arc-shaped curved surface. This arrangement allows the balancing belt 32 to change its extension direction through the arc-shaped curved surface. Moreover, when the movable seat 33 moves, the movable seat 33 can drive the balancing belt 32 to move through the steering member 34, thereby eliminating the lateral separation force of the buckle 100.

[0064] For example, the steering component 34 uses a roller, and the arcuate surface is the outer surface of the roller.

[0065] In this embodiment, see Figure 1 and Figure 2 The bracket 1 is provided with a groove 111 extending circumferentially along the support 2, and the movable seat 33 is provided with a slider 331, which is embedded in the groove 111 and slides in cooperation with the groove 111. This arrangement allows the movable seat 33 to move circumferentially along the support 2 by driving the slider 331 to slide within the groove 111.

[0066] Optionally, the release assembly 4 also includes a detection element disposed in the housing 41 and connected to the release element 42, for detecting the release force applied by the release element 42 to the buckle 100. This configuration allows operators to quickly and intuitively obtain the release force applied by the release element 42 to the buckle 100 when it is finally released, thus improving testing efficiency.

[0067] In this embodiment, the end of the release member 42 is provided with a tapered head, and the release member 42 contacts the buckle 100 through the tapered head. The design of the tapered head allows it to apply a release force to the buckle 100 in a point contact manner, which helps to improve the accuracy of the release force application position.

[0068] For example, the release component 4 is a push-pull force gauge, the release element 42 is the loading rod of the push-pull force gauge, and the detection element is the sensor of the push-pull force gauge.

[0069] Optionally, the counterweight 31 includes multiple counterweight blocks of different weights, and the balance belt 32 can be connected to one of the counterweight blocks. This configuration allows the balance assembly 3 to accurately reproduce the stress environment of different types of buckles 100 during operation, further improving the reliability of the test data.

[0070] For example, the counterweights are weights connected to the balance belt 32 via hooks thereon. The weights of the multiple counterweights include, but are not limited to, 0.45 kg and 0.90 kg.

[0071] Optionally, the buckle release force testing device also includes a linear drive unit disposed on the bracket 1, the output end of which is connected to the support 2 for driving the support 2 to move vertically.

[0072] In this embodiment, see Figure 2 The buckle release force testing device also includes a drive shaft 7. The bracket 1 includes a working platform 11, a linear drive (not shown in the figure) and a support 2 respectively disposed on the upper and lower sides of the working platform 11. The drive shaft 7 passes through the working platform 11 in the vertical direction and slides in cooperation with the working platform 11. The support 2 is connected to one end of the drive shaft 7, and the output end of the linear drive is connected to the other end of the drive shaft 7 for driving the drive shaft 7 to move the support 2 vertically.

[0073] See Figure 1 The chute 111 is installed on the working platform 11.

[0074] Optionally, the buckle release force testing device also includes a traveling component disposed at the bottom of the bracket 1. The traveling component is used to drive the bracket 1 to move, thereby realizing the movement of the entire buckle release force testing device.

[0075] Specifically, the walking assembly includes multiple walking wheels.

[0076] Example 2

[0077] like Figure 4 As shown, this embodiment provides a method for testing the release force of a hook and loop fastener. The hook and loop fastener release force testing device of Embodiment 1 is used to test the release force required to release the hook and loop fastener 100. The hook and loop fastener 100 with a dual-action release structure includes two release parts 101.

[0078] The method for testing the release force of a hook and loop includes the following steps:

[0079] S1. Place the buckle 100 on the support 2 and connect the balance belt 32 to the buckle 100 and the counterweight 31.

[0080] Specifically, first, place the buckle 100 in the center of the circular support 2; then, select a counterweight of appropriate weight according to the type of buckle 100, connect one end of the balance belt 32 to the buckle 100, and connect the other end to the selected counterweight, so that part of the balance belt 32 fits against the curved surface; at the same time, drive the clamping member 62 to press the connecting belt 5 against the clamping seat 61, and connect the end of the connecting belt 5 away from the clamping member 6 to the buckle 100.

[0081] S2. Determine whether the end of the balance belt 32 connected to the buckle 100 extends horizontally. If yes, proceed to step S3. If no, drive the support 2 to move vertically until the end of the balance belt 32 connected to the buckle 100 extends horizontally.

[0082] Specifically, if the end of the balance belt 32 connected to the buckle 100 fails to extend horizontally, the linear drive is activated, and the linear drive drives the transmission shaft 7 to slide vertically relative to the work platform. The transmission shaft 7 drives the support seat 2 to move vertically. After the end of the balance belt 32 connected to the buckle 100 extends horizontally, the linear drive is deactivated.

[0083] S3. Determine whether the end of the balancing component 3 connected to the latch 100 extends along the release direction of the latch 100. If yes, proceed to step S4. If no, drive the balancing component 3 to move until the end of the balancing component 3 connected to the latch 100 extends along the release direction of the latch 100. When the end of the balancing component 3 connected to the latch 100 extends along the release direction of the latch 100, the force exerted by the balancing component 3 on the latch 100 helps the latch 100 to release quickly after the latch 100 is released.

[0084] When the latch 100 is a single-action release structure, such as a five-point latch 100, the release direction of the latch 100 is the direction of the line connecting the center of the latch 100 to the edge; when the latch 100 is a double-action release structure, such as a two-sided press-type latch 100, the release direction of the latch 100 is perpendicular to the movement direction of the release member 42.

[0085] S4. Determine the structure of buckle 100:

[0086] If the latch 100 is a single-action release structure, the release member 42 is driven to move to contact the latch 100 and apply a release force to the latch 100 until the latch 100 is released.

[0087] Specifically, taking the five-point hook and loop fastener 100 as an example, the operator holds the release component 4 directly above the hook and loop fastener 100, driving the release component 42 to move vertically so that the conical head of the release component 42 moves to contact the hook and loop fastener 100 and pushes against it until the hook and loop fastener 100 is released. During the pushing process, the conical head applies a release force to the hook and loop fastener 100, and the detection component can detect the value of the release force applied by the conical head in real time.

[0088] If the latch 100 is a double-action release structure, then execute steps S41 to S44;

[0089] S41, Release a release unit 101.

[0090] S42, drive the release member 42 to move to contact the unreleased release part 101, and apply a release force to the unreleased release part 101 until the unreleased release part 101 is released.

[0091] Specifically, taking the double-sided press-type hook and loop fastener 100 as an example, in step S41, the operator manually presses the release part 101 to release it. In step S42, the operator holds the release assembly 4 from the side of the hook and loop fastener 100, driving the release member 42 to move horizontally, so that the conical head of the release member 42 moves to contact the hook and loop fastener 100 and push against it until the hook and loop fastener 100 is released. The detection unit detects the value of the release force applied by the conical head.

[0092] S43. Place the buckle 100 back on the support 2 and connect the buckle 100 to the multiple balance belts 32.

[0093] S44. Release the release unit 101 released in step S43, and repeat step S42.

[0094] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here.
