[0029] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0030] refer to Figure 1 and Figure 2 The gas spring fulcrum positioning device provided in the present application mainly includes: a frame 1, a longitudinal guide rail 2, an upper slide plate 3, a lower slide plate 4, a lifting drive assembly, a transverse guide rail 5, a transverse push plate 6, a transverse drive device 7, a counterweight assembly, a thrust adjustment assembly and a gas spring 8.

[0031] The frame 1 carries the above-mentioned components. The inner wall of the frame 1 is provided with two longitudinally distributed longitudinal guide rails 2. An upper slide 3 and a lower slide 4 are slidably provided on the longitudinal guide rails 2. The lifting drive assembly on the frame 1 is connected to the upper slide 3, and the upper slide 3 is driven by the lifting drive assembly to slide up and down along the longitudinal slide rails. The lifting drive assembly is connected to the control unit 22 to realize the parameter control of the lifting drive assembly. The upper slide 3 is provided with a transverse guide rail 5, a transverse push plate 6 and a transverse drive device 7. The transverse push plate 6 is installed on the transverse guide rail 5, and the transverse push plate 6 is connected to the transverse drive device 7. The transverse push plate 6 is driven by the transverse drive device 7 to move along the transverse guide rail 5 in the forward direction.

[0032] The transverse driving device 7 includes a transverse adjusting screw 71 and a transverse motor 72. The transverse adjusting screw 71 is connected to the driving end of the transverse motor 72. The transverse motor 72 provides a rotational force to the transverse adjusting screw 71 to drive the transverse adjusting screw 71 to rotate, thereby pushing the transverse push plate 6 connected to the transverse adjusting screw 71 to move along the transverse guide rail 5.

[0033] The counterweight assembly simulates the transfer position at the top of the door body and is installed on the frame 1. The counterweight assembly simulates the weight of the door panel waiting for the supporting components, and the weight of the counterweight part is adjustable. The corresponding counterweight can be selected according to the required weight of the door panel to achieve the adjustment of different counterweights.

[0034] The thrust adjustment assembly is fixedly mounted on the lower slide plate 4, and the thrust end of the thrust adjustment assembly applies a thrust to the counterweight assembly, thereby pushing the counterweight assembly to rotate around the transfer position connected to the frame 1 through the hinge assembly 21. The two fulcrums of the gas spring 8 are respectively connected to the first gas spring connection point of the counterweight assembly and the second gas spring connection point of the transverse push plate 6. There are multiple mounting holes arranged laterally on the upper adjustment plate 12, and the gas spring 8 can select the mounting holes to be connected to realize the installation of the fulcrum of the gas spring 8 at different positions on the upper adjustment plate 12. By controlling and adjusting the front and rear positions of the fulcrum of the gas spring 8, the gas spring 8 can be automatically popped open, thereby determining the fulcrum position of the gas spring 8.

[0035] The working principle of the present application is: by adjusting the front and rear positions of the fulcrum of the gas spring 8, the gas spring 8 can be automatically popped open, and combined with the thrust adjustment component, under the action of a certain force, the door panels and other products that need to be operated can be automatically opened, so as to determine the fulcrum position of the gas spring 8, and finally achieve the purpose of accurate positioning of the fulcrum of the gas spring 8.

[0036] In this way, the gas spring 8 of the selected theoretical value can be accurately positioned by adjusting the fulcrum of the gas spring 8, thereby significantly reducing the number of selections, avoiding repeated verification and assembly of several models of gas springs 8 resulting in low efficiency and low accuracy, and effectively reducing the selection cost.

[0037] In a specific embodiment, the lifting drive assembly includes: two longitudinal lead screws 9, a synchronous belt 10 and a lead screw motor 11, wherein the two longitudinal lead screws 9 are respectively connected to the left and right walls of the upper slide 3 through a lead screw nut, a synchronous pulley is provided on the top of the longitudinal lead screw 9, and the synchronous belt 10 is mounted on the two synchronous pulleys. The longitudinal lead screws 9 on the left and right sides are connected through the synchronous belt 10 on the top to ensure synchronous rotation of the left and right sides, thereby ensuring the consistency of the left and right side movements during the lifting and lowering movement of the upper slide 3. The driving end of the lead screw motor 11 is connected to the longitudinal lead screw 9 on one side, thereby driving the longitudinal lead screw 9 to rotate. During the rotation of the longitudinal lead screw 9, the longitudinal lead screw 9 on the other side is driven to rotate synchronously through the synchronous belt 10, and finally drives the upper slide 3 to move up and down along the longitudinal guide rail 2.

[0038] In a specific embodiment, the counterweight assembly mainly includes: two upper adjustment assemblies, two lower adjustment assemblies, a counterweight block 16 and a connecting rod 17. The two upper adjustment assemblies are rotatably mounted on the top of the frame 1 through a hinge assembly 21, and the length of the upper adjustment assembly is adjustable. The two lower adjustment assemblies are respectively connected to the two upper adjustment assemblies, and the length of the two upper adjustment assemblies is adjustable. The counterweight block 16 connects the two lower adjustment assemblies or connects the two upper adjustment assemblies, and the connecting rod 17 connects the two lower adjustment assemblies.

[0039] The upper adjustment assembly includes an upper adjustment plate 12, an upper sliding adjustment plate 13 and bolts. The upper sliding adjustment plate 13 is slidably connected to the inside of each upper adjustment plate 12. The upper sliding adjustment plate 13 can move forward and backward on the upper adjustment plate 12 to adjust the splicing length. After the length is adjusted, the two are fastened by bolts. In this way, the force conditions of the gas spring 8 at different distances can be simulated.

[0040] The lower adjustment assembly includes a longitudinal adjustment plate 14 connected to the front end of each upper sliding adjustment plate 13, a longitudinal sliding adjustment plate 15 slidably connected to each longitudinal adjustment plate 14, and a bolt for locking the longitudinal adjustment plate 14 and the longitudinal sliding adjustment plate 15. The counterweight 16 is connected to the longitudinal adjustment plate 14 or to two longitudinal sliding adjustment plates 15. The left and right longitudinal sliding adjustment plates 15 are connected by a connecting rod 17, so that the left and right longitudinal sliding adjustment plates 15 move synchronously.

[0041] A locking mechanism 20 is provided at the bottom of the lower slide plate 4. For example, the locking mechanism 20 is four screws with handles. By locking the screws inside the frame 1, the lower slide plate 4 can be restricted from sliding down along the longitudinal guide rail 2, thereby fixing the longitudinal position of the lower slide plate 4.

[0042] In the above embodiment, by adjusting the installation form of the longitudinal sliding adjustment plate 15 and the counterweight block 16, the force conditions of the gas spring 8 under different gravity and at different center of gravity points can be achieved. The weight selection of the counterweight part is based on the weight of the door panel and other products minus the weight of the two upper adjustment components and the two lower adjustment components. Therefore, the weight of the counterweight part that matches the weight of the door panel can be selected. The specifications of the upper adjustment plate 12, the upper sliding adjustment plate 13, the longitudinal adjustment plate 14, the longitudinal sliding adjustment plate 15, and the counterweight block 16 are not limited to one, and can be multiple, and by changing different matching forms, a full range of force simulation can be achieved.

[0043] Regarding the structure of the thruster adjustment plate 18, specifically, it includes a thruster adjustment plate 18 and a thruster 19. The thruster adjustment plate 18 is detachably mounted on the upper slide plate 3, and the thruster adjustment plate 18 can be mounted at different positions on the lower slide plate 4. The thruster 19 is mounted on the thruster adjustment plate 18, and the front end of the thruster 19 contacts the connecting rod 17. According to the front and rear positions of the thruster adjustment plate 18, the thruster 19 can generate a pre-pressure value, and this pre-pressure value can be adjusted according to the required size of the operating force. The thruster 19 can apply thrust to the connecting rod 17, thereby pushing the counterweight assembly.

[0044] In order to facilitate the adjustment of the position of the thruster adjustment plate 18, a plurality of position adjustment holes are provided on the thruster adjustment plate 18. By selecting the position adjustment holes for bolt locking connection, the distance between the thruster 19 and the connecting rod 17 can be adjusted, and the adjustment is more convenient and quick.

[0045] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.
