Description

Technical Field

[0001] This utility model relates to the field of vehicle testing technology, specifically to a vehicle side protection and mooring point testing device. Background Technology

[0002] For vehicles in categories N2, N3, O3, and O4, their protective devices require regulatory testing to determine their stiffness. According to national standards, the testing method for side protection devices involves applying static pressure perpendicularly to various parts of the device's outer surface using a circular flat pressure head; the resulting deformation should meet required limits. For N2 and N3 category trucks, strength testing of the cargo box fastening points is also required to ensure they can withstand sufficient tensile force without permanent deformation.

[0003] Currently, the testing institutions used for stiffness testing of lateral protection devices and strength testing of anchor points are basically independent devices, and there is no testing device that can be used for both types of tests. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model proposes a vehicle side protection and mooring point testing device, which can be used for two types of side protection and mooring point testing.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a vehicle side protection and fastening point testing device, including a base, on which a threaded sleeve is fixedly provided;

[0006] The test assembly includes a threaded post, a pressure plate, and a tension member. The threaded post is threadedly connected to a threaded sleeve, with both ends extending beyond the sleeve. One end is connected to the pressure plate, and the other end is connected to the tension member.

[0007] Force gauges are provided at both ends of the threaded column, and are connected to the pressure plate and the tensioning component respectively.

[0008] During the side protection device stiffness test, a pressure plate is placed against the vehicle's side protection device, with a base supporting the load, such as a wall or support column. Rotating the threaded column relative to the threaded sleeve moves the pressure plate, applying a vertical static pressure to the side protection device. The force value is obtained using a force gauge. For a single-point strength test of the anchoring point, a tension member is connected to the anchoring point. Rotating the threaded column relative to the threaded sleeve moves the anchoring point, and the force value is obtained using a force gauge. For a double-point strength test of the anchoring point, two anchoring points are connected by a chain. The pressure plate is placed against the middle of the chain, and rotating the threaded column relative to the threaded sleeve moves both anchoring points simultaneously. The force value is obtained using a force gauge.

[0009] The advantages of the above-mentioned vehicle side protection and fastening point testing device are that it can be used for both the stiffness test of the vehicle's side protection device and the strength test of the vehicle's fastening point, and it can be used for single-point strength test or double-point strength test, with a wide range of applications.

[0010] Furthermore, the bottom of the base is provided with a groove, the threaded sleeve is fixedly inserted into the top of the base and one end is connected to the groove, and the end of the threaded column connected to the tension member is located in the groove.

[0011] The recessed space at the bottom of the base is for the threaded post to extend, so as to leave space for the tension component.

[0012] Furthermore, the test assembly also includes lever arms, with two lever arms symmetrically arranged on the outer wall of the threaded column.

[0013] The two lever arms make it easy for the user to grip and rotate the threaded column, and facilitate the application of force.

[0014] Furthermore, the pressure plate is a cylindrical disc-shaped structure.

[0015] The flat, cylindrical, disc-shaped structure facilitates the application of pressure to the opposite protective device.

[0016] Furthermore, the tensioning element is a ring structure or a hook-shaped structure.

[0017] The ring or hook-shaped structure facilitates connection to the anchoring point.

[0018] Furthermore, one end of the threaded column is fixedly connected to the connecting rod by bolts, and a slot is provided on the pressure plate, with the connecting rod and the slot of the pressure plate having clearance fit; the other end of the threaded column is fixedly connected to the tension member by bolts.

[0019] One end of the connecting rod is fixed to the threaded column by bolts, and the other end is fitted with the pressure plate with clearance, so that when the connecting rod rotates relative to the pressure plate, it can apply pressure to the pressure plate and limit the pressure plate at the same time.

[0027] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0028] Please see Figure 1 and Figure 2 This utility model provides a vehicle side protection and anchorage testing device, including a base 10, a testing component 20 and a force gauge 30.

[0029] Specifically, a threaded sleeve 11 is fixedly mounted on the base 10. The test assembly 20 includes a threaded post 21, a pressure plate 22, and a tension member 23. The threaded post 21 is threadedly connected to the threaded sleeve 11, and both ends extend out of the threaded sleeve 11 and are fixedly connected to the force gauge 30 by bolts. One end of the force gauge 30 is connected to the pressure plate 22, and the other end is connected to the tension member 23.

[0030] When conducting a stiffness test on the vehicle's side protection device, the pressure plate 22 is placed against the side protection device, and the base 10 is used to bear the force, resting against a wall or support column. Rotating the threaded column 21 moves it relative to the threaded sleeve 11, thereby causing the pressure plate 22 to apply a vertical static pressure to the side protection device. The force value is obtained through the force gauge 30. When conducting a single-point strength test on the anchor point, the tension member 23 is connected to the anchor point. Rotating the threaded column 21 moves it, pulling the anchor point, and the force value is obtained through the force gauge 30. When conducting a double-point strength test on the anchor point, two anchor points can be secured with a chain. The pressure plate 22 is placed against the middle of the chain, and rotating the threaded column 21 moves it, simultaneously pulling both anchor points. The force value is obtained through the force gauge 30, and the force situation at each anchor point is calculated through force analysis.

[0031] Specifically, a groove is provided at the bottom center of the base 10, and a threaded sleeve 11 is fixedly inserted at the top center of the base 10, with one end communicating with the groove. The end of the threaded post 21 connected to the tension member 23 is located in the groove. The space in the groove is left to facilitate the extension of the threaded post and to accommodate the tension member, so as to conduct a fastening point test, without affecting the load-bearing capacity of the base.

[0032] Specifically, the test assembly 20 also includes lever arms 24, with two lever arms 24 symmetrically arranged on the outer wall of the threaded post 21. In this embodiment, the lever arms are welded to the threaded post, making it easy for the user to grip and rotate the threaded post for easy application of force.

[0033] Furthermore, the pressure plate 22 is a cylindrical disc structure, and the tensioning component 23 is a ring-shaped or hook-shaped structure. The flat cylindrical disc structure facilitates the attachment and application of pressure to the opposite protective device, while the ring-shaped or hook-shaped structure facilitates connection with the fastening point.

[0034] The pressure plate 22 also has a circular slot. The force gauge 30 of the threaded post 21, near one end of the pressure plate 22, is fixedly connected to the connecting rod 25 by bolts. The connecting rod 25 has a clearance fit with the slot. The force gauge at the other end of the threaded post 21 is also fixedly connected to the tension member 23 by bolts. For example... Figure 2 As shown, the connecting rod 25 is clearance-fitted with the pressure plate 22, which allows the threaded column and the force gauge to drive the connecting rod to rotate relative to the pressure plate, while applying pressure to the pressure plate. The connecting rod can also act as a limit to prevent the pressure plate from shifting.

[0035] The working principle of the aforementioned vehicle side protection and anchoring point testing device is as follows: During the stiffness test of the vehicle's side protection device, the pressure plate 22 is placed against the side protection device, and the base 10 is placed against a wall or support column to bear the force. The lever arm 24 is held, and the threaded column 21 is rotated, causing it to move axially relative to the threaded sleeve 11. This applies a vertical static pressure to the side protection device via the pressure plate 22, and the force value is obtained through the force gauge 30. During the single-point strength test of the anchoring point, the tension member 23 is connected to the anchoring point. Similarly, rotating the threaded column 21 moves the anchoring point, and the force value is obtained through the force gauge 30. During the double-point strength test of the anchoring point, two anchoring points can be secured with a chain. The pressure plate 22 is placed against the middle of the chain, and the threaded column 21 is rotated to simultaneously pull both anchoring points. After obtaining the force value through the force gauge 30, the force situation of each anchoring point is calculated through force analysis.

[0036] The aforementioned vehicle side protection and mooring point testing device can be used for both the stiffness test of the vehicle's side protection device and the strength test of the vehicle's mooring point. Furthermore, during the mooring point strength test, it can be used for both single-point strength tests and double-point strength tests, making it widely applicable and highly practical.

[0037] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
