[0031] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0032] like Figure 1 to Figure 2 As shown, the embodiment of the utility model provides a test device for opening and closing test of concealed hinges, comprising:

[0033] A driving member, on which a rotating arm 100 is arranged;

[0034] A connecting rod 102, the connecting rod 102 is connected to one end of the rotating arm 100, and an electromagnet 104 is provided at one end of the connecting rod 102 away from the rotating arm 100;

[0035] The connecting frame 106 is mounted on the mounting portion 110. The mounting portion 110 is suitable for being hinged to the frame through a concealed hinge. A slide groove 108 is provided on the connecting frame. The electromagnet 104 is slidably disposed in the slide groove 108.

[0036] The mounting portion 110 is adapted to rotate relative to the frame under the drive of the rotating arm 100 through the cooperation between the electromagnet 104 and the slide slot 108 .

[0037] According to the test device for the opening and closing test of the concealed hinge provided by the embodiment of the utility model, the rotating arm 100 is driven to rotate by the driving member, and then the electromagnet 104 is made to slide in the slide groove 108 of the connecting frame 106 through the connecting rod 102. This design can simulate the opening and closing process of the concealed hinge in actual application, and provides a real and reliable simulation environment for the performance test of the concealed hinge. Since the cooperation between the electromagnet 104 and the slide groove 108 can accurately control the moving position and speed, the device can accurately test the mechanical properties of the concealed hinge during the opening and closing process. This is very important for evaluating the performance, durability and safety of the concealed hinge. By adjusting the rotation angle, speed and direction of the driving member, as well as the configuration of the connecting rod 102 and the electromagnet 104, the test device can adapt to the testing requirements of concealed hinges of different specifications, types and uses. This high flexibility and adaptability make the device have a wide range of application prospects. The test device realizes the opening and closing test of the concealed hinge through automatic control, which greatly improves the test efficiency. At the same time, due to the repeatability and precision of the testing process, it can also reduce the impact of human factors on the test results and improve the accuracy and reliability of the test.

[0038] According to an embodiment of the present invention, a counterweight block 112 is detachably provided on the mounting portion 110 , and the connecting frame 106 is mounted on the counterweight block 112 .

[0039] Please continue to see Figure 1 to Figure 2 The test device includes a driving member, on which a rotating arm 100 is arranged. The driving member can be a motor, a cylinder or other equipment capable of providing rotational power. The rotating arm 100 is an important component connecting the driving member and the connecting rod 102, and is responsible for transmitting the rotational motion of the driving member to the mounting portion 110.

[0040] The connecting rod 102 is connected to one end of the rotating arm 100, and the other end thereof is provided with an electromagnet 104. The design of the connecting rod 102 ensures that the motion conversion from the rotating arm 100 to the electromagnet 104 can be accurate and stable. The electromagnet 104 is a key part of the test device, which can cooperate with the slide slot 108 on the connecting frame 106 through electromagnetic force to realize the rotation of the mounting portion 110.

[0041] The connecting frame 106 is mounted on the mounting portion 110, and the mounting portion 110 is hinged to the frame through a concealed hinge. A slide groove 108 is provided on the connecting frame 106, and the electromagnet 104 can slide in the slide groove 108. The design of the slide groove 108 ensures the stability and accuracy of the electromagnet 104 during the movement, thereby ensuring the accuracy of the test results.

[0042] During the test, the driving member drives the rotating arm 100 to rotate, and the rotating movement of the rotating arm 100 drives the electromagnet 104 to rotate synchronously through the connecting rod 102. The electromagnet 104 slides in the slide slot 108 of the connecting frame 106, and through the cooperation of the electromagnetic force and the slide slot 108, the mounting portion 110 is pushed to rotate relative to the frame. This rotation process simulates the opening and closing process of the concealed hinge in actual use. In this way, the time-consuming and labor-intensive problem of manual testing in the related art can be solved, and the test accuracy of the test device can also be guaranteed.

[0043] According to an embodiment of the present invention, the connecting frame 106 includes a connecting portion 114 and a sliding portion 116 . The connecting portion 114 is mounted on the counterweight 112 , and the sliding slot 108 is provided on the sliding portion 116 .

[0044] The connecting frame 106 is mainly composed of a connecting portion 114 and a sliding portion 116. The connecting portion 114 is the portion where the connecting frame 106 is connected to the counterweight 112. This portion is designed with an appropriate interface or structure so as to be tightly and firmly connected to the counterweight 112. The interface design may include but is not limited to screw holes, buckles, slots, etc., depending on the connection method and requirements of the counterweight 112. The connecting portion 114 also needs to consider the load-bearing capacity and stability to ensure that it will not loosen or break when the connecting frame 106 carries a heavy object.

[0045] The sliding part 116 is a key part for the connecting frame 106 to realize the sliding function. This part is designed with a slide groove 108. The shape, size and position of the slide groove 108 need to be determined according to the actual application scenario and sliding requirements. The material of the slide groove 108 needs to be selected from wear-resistant and corrosion-resistant materials to ensure that the sliding performance will not be significantly reduced after long-term use. The sliding part 116 also needs to be designed with appropriate guide mechanisms, such as guide grooves, guide wheels, etc., to ensure the stability of the connecting frame 106 during the sliding process.

[0046] According to an embodiment of the present invention, a base 118 is further included, and the driving member and the frame are installed on the base 118 .

[0047] The base 118 is the supporting structure of the whole system, which provides a foundation for installation and fixing. The design of the base 118 needs to take into account the stability, load-bearing capacity and adaptability of the installation environment of the system.

[0048] The design of the base 118 also needs to take into account the shockproof and vibration reduction functions to reduce the impact of the external environment on the system and ensure its stable operation. In addition, the base 118 may also be equipped with a height adjustment mechanism to adapt to the needs of different installation environments.

[0049] According to one embodiment of the present invention, the framework includes:

[0050] A pair of vertical frames 120, the pair of vertical frames 120 are arranged opposite to each other, and the panel is suitable for being hinged to one of the vertical frames 120 through a concealed hinge;

[0051] A pair of transverse frames 122 are disposed between the pair of vertical frames 120 , and the mounting portion 110 includes a panel mounted between the pair of vertical frames 120 and the pair of transverse frames 122 .

[0052] A pair of vertical frames 120 are arranged opposite to each other to form a basic vertical support structure. The panel (i.e., a part of the mounting portion 110) is hinged to one of the vertical frames 120 through a concealed hinge to achieve the opening and closing action. A pair of lateral frames 122 are arranged between the pair of vertical frames 120, and they are connected to the vertical frames 120 to form a stable rectangular frame together.

[0053] According to an embodiment of the present invention, a pair of vertical frames 120 are detachably connected to a pair of horizontal frames 122 .

[0054] The detachable connection makes the assembly and disassembly process of the frame easier and faster. This not only facilitates the transportation and storage of the equipment, but also improves the convenience of the equipment during use and maintenance. Through the detachable connection, the size and shape of the frame can be adjusted according to actual needs. This enables the test device to adapt to the testing needs of concealed hinges of different specifications and types, and improves the versatility and adaptability of the equipment. When a component in the frame is damaged or needs to be replaced, it can be removed through a simple disassembly operation and a new component can be quickly installed. This design reduces maintenance time and cost and improves the reliability and service life of the equipment.

[0055] According to one embodiment of the present invention, the electromagnet 104 is adapted to switch between an insertion position and a withdrawal position relative to the slide slot 108 . In the insertion position, the electromagnet 104 is adapted to slide relative to the slide slot 108 . In the withdrawal position, the electromagnet 104 is relatively far away from the slide slot 108 .

[0056] In the inserted position, the electromagnet 104 fits tightly in the slide slot 108, forming a good matching relationship with the slide slot 108. This enables the electromagnet 104 to slide accurately and stably relative to the slide slot 108 under the action of the driving force, thereby ensuring that the mounting portion 110 (such as a panel) can rotate smoothly and accurately relative to the frame, simulating the opening and closing process of the concealed hinge.

[0057] In the withdrawal position, the electromagnet 104 is relatively far away from the chute 108 and no longer contacts the chute 108. This design allows the electromagnet 104 to be easily withdrawn from the chute 108, which is convenient for equipment maintenance, replacement or adjustment. In addition, when the test is finished or the test needs to be stopped, placing the electromagnet 104 in the withdrawal position can also avoid unnecessary wear or damage to the chute 108 and the electromagnet 104.

[0058] By designing the electromagnet 104 to be switchable between insertion and withdrawal positions, safety accidents caused by accidental falling off or loss of control of the electromagnet 104 during the test process can be avoided. In the withdrawal position, even if the electromagnet 104 loses driving force, it will not suddenly rush into the slide slot 108 due to inertia or external force, thereby ensuring the safety of the test process.

[0059] According to one embodiment of the utility model, in the insertion position, the mounting portion 110 is adapted to rotate relative to the frame under the drive of the rotating arm 100 through the cooperation between the electromagnet 104 and the slide slot 108;

[0060] In the withdrawn position, the mounting portion 110 is adapted to be restored to an initial position relative to the frame under the action of the concealed hinge.

[0061] In the inserted position, the electromagnet 104 fits tightly in the slide slot 108, forming a good matching relationship with the slide slot 108. At this time, the mounting portion 110 (such as a panel) rotates relative to the frame under the drive of the rotating arm 100 through the matching of the electromagnet 104 and the slide slot 108. This design enables the mounting portion 110 to smoothly and accurately simulate the opening and closing process of the concealed hinge, thereby evaluating the performance and durability of the concealed hinge.

[0062] When the electromagnet 104 is in the withdrawn position, it is relatively far away from the slide slot 108 and no longer generates direct driving force on the mounting portion 110. In this case, the mounting portion 110 will mainly rely on the structural characteristics and elasticity of the concealed hinge itself to return to the initial position relative to the frame. This design allows testers to observe and analyze the natural state and movement characteristics of the concealed hinge without external force without using the electromagnet 104.

[0063] By switching the position of the electromagnet 104, the test device can support two different test modes. In the inserted position, the electromagnet 104 and the slide slot 108 cooperate to perform accurate opening and closing tests; in the withdrawn position, the natural state and movement characteristics of the concealed hinge are observed and analyzed. This flexibility enables the test device to meet more diverse test needs.

[0064] In the withdrawn position, the electromagnet 104 no longer generates direct driving force on the mounting portion 110, thereby avoiding safety accidents caused by loss of control or failure of the electromagnet 104. At the same time, the structural characteristics and elasticity of the concealed hinge can ensure that the mounting portion 110 will not be damaged or deformed when it returns to the initial position.

[0065] By combining the two test modes, the test device can more comprehensively evaluate the performance and durability of concealed hinges. The opening and closing test in the inserted position can evaluate the performance of concealed hinges when subjected to external forces; while the natural state test in the withdrawn position can evaluate the stability and reliability of concealed hinges when not subjected to external forces. This comprehensive performance evaluation helps to improve the accuracy and reliability of test results.

[0066] According to an embodiment of the present invention, there are at least two electromagnets 104 , and the at least two electromagnets 104 are spaced apart along the length direction of the rotating arm 100 .

[0067] By arranging a plurality of electromagnets 104 at intervals along the length of the rotating arm 100, the driving force on the mounting portion 110 can be dispersed and balanced. This helps ensure that the mounting portion 110 rotates more smoothly and stably relative to the frame when driven by the rotating arm 100, and reduces vibration or deviation caused by uneven driving force.

[0068] The arrangement of multiple electromagnets 104 allows the size and distribution of the driving force to be adjusted as needed. By independently controlling the electromagnetic force of each electromagnet 104, more precise driving force regulation can be achieved to meet the testing requirements of different loads, speeds and opening and closing angles.

[0069] During the test, if one of the electromagnets 104 fails or fails, the other electromagnets 104 can still continue to work, ensuring the continuity and reliability of the test. This redundant design improves the fault tolerance and stability of the test device.

[0070] By arranging multiple electromagnets 104 at intervals along the length direction of the rotating arm 100, the performance requirements of a single electromagnet 104 can be reduced, thereby simplifying the structural design of the electromagnet 104. This not only reduces the manufacturing cost, but also helps to improve the reliability and durability of the electromagnet 104.

[0071] According to an embodiment of the present invention, a control unit 124 is further included. The control unit 124 is electrically connected to the driving element and the electromagnet 104 .

[0072] The control unit 124 is electrically connected to the driving element and the electromagnet 104, thereby realizing centralized control and management of the entire test device.

[0073] First, the electrical connection between the control unit 124 and the driver allows the parameters of the driver such as the rotation speed and angle to be precisely adjusted by the control unit 124. This helps to simulate the opening and closing process of the concealed hinge under different conditions, thereby more comprehensively evaluating its performance.

[0074] Secondly, the electrical connection between the control unit 124 and the electromagnet 104 facilitates the switching of the electromagnet 104 between the insertion position and the withdrawal position. Through the control unit 124, the user can easily place the electromagnet 104 in the desired position and adjust the electromagnetic force of the electromagnet 104 as needed. This flexibility enables the test device to adapt to different test requirements and improve test efficiency.

[0075] In addition, the introduction of the control unit 124 also improves the safety of the test device. By real-time monitoring and controlling the status of key components such as the driving member and the electromagnet 104, the control unit 124 can promptly detect and handle abnormal situations to avoid the occurrence of safety accidents.

[0076] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
