[0025] Example 1
[0026] Reference Figure 1 to Figure 5 , which is the first embodiment of the utility model, and provides a door glass lifter, which includes a main body assembly 100 and a connecting assembly 200. The cooperation of the main body assembly 100 and the connecting assembly 200 can make each small tooth block be divided into two and combined at will. If a small tooth block is damaged, only the corresponding part needs to be replaced, and there is no need to replace the rack as a whole, which reduces the maintenance cost and difficulty.
[0027] The main assembly 100 includes a glass support plate 101, a guide plate 102, a gear 103 and a rack 104. The guide plate 102 is arranged on one side of the glass support plate 101, the gear 103 is movably connected to one side of the guide plate 102, and the rack 104 is located on one side of the gear 103, and the rack 104 and the gear 103 are meshed.
[0028] The glass support plate 101 is mainly responsible for directly supporting the vehicle window glass, ensuring that the glass can be firmly mounted on the lifting device, and providing a mounting and fixing base for the glass so that the glass can move smoothly with the movement of the lifting device. The guide plate 102 guides the glass to move in the correct direction during the lifting process to prevent the glass from tilting or deviating from the predetermined track. Multiple racks 104 can be hinged together, and the rack 104 slides on one side of the guide plate 102. The gear 103 is driven to rotate by the starting motor, and the gear 103 rotates to drive the rack 104 to move. The movement of the rack 104 can drive the glass support plate 101 to move to complete the lifting of the glass.
[0029] The connecting assembly 200 is disposed on the rack 104 , and includes a connecting member 201 and a triggering member 202 . The connecting member 201 is located at one side of the rack 104 , and the triggering member 202 is located on the connecting member 201 .
[0030] There are two groups of connecting parts 201, both of which are arranged on one side of the rack 104. By splicing the two groups of connecting parts 201 together, the two tooth blocks can be quickly spliced together, which can greatly improve the installation efficiency on the production line and the speed of replacing the rack 104 part during later maintenance, saving time and labor costs. When the rack 104 part is damaged, there are two groups of trigger parts 202, both of which are arranged on the connecting part 201. The setting of the trigger part 202 can release the limit of the connecting part 201, and then the rack 104 can be separated, which is convenient for subsequent replacement.
[0031] Example 2
[0032] Reference Figure 1 to Figure 5 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment.
[0033] Specifically, the connecting member 201 includes a clamping frame 201a and an inserting block 201b. The clamping frame 201a is fixed to one side of the rack 104, and the inserting block 201b is fixed to one end of the clamping frame 201a.
[0034] A slot corresponding to the plug-in block 201b is provided at the top of the card frame 201a. When the two tooth blocks need to be spliced together to form the rack 104, the two card frames 201a are snapped together, and the plug-in block 201b is inserted into the slot, thereby completing the splicing of the card frames 201a, and the tooth blocks can be spliced into the rack 104.
[0035] Specifically, the connecting member 201 further includes a clamping block 201c and a moving rod 201d. The clamping block 201c is hinged to one side of the clamping frame 201a, and the moving rod 201d is fixed to one side of the clamping block 201c.
[0036] The clamping block 201c is set to be semicircular. When the two clamping frames 201a are spliced together, the two clamping blocks 201c will squeeze each other to make the clamping block 201c rotate. After the clamping frames 201a are spliced together, the two clamping blocks 201c are separated and returned to their original positions. At this time, the mutual limitation of the two clamping blocks 201c can prevent the two clamping frames 201a from falling off after being spliced together. When the two clamping frames 201a need to be separated, the moving rod 201d is moved. The movement of the moving rod 201d can drive the two to rotate, so that the plane of the clamping block 201c faces upward. At this time, the two clamping blocks 201c will release the mutual limitation, and then the two clamping frames 201a can be separated.
[0037] Specifically, the connecting member 201 further includes a support plate 201e and a first spring 201f. The support plate 201e is fixed to one end of the moving rod 201d, and the first spring 201f is fixed to the top of the support plate 201e.
[0038] When the moving rod 201d is moved, a pulling force can be applied to the first spring 201f. The movement of the moving rod 201d can drive the two clamping blocks 201c to rotate so that the plane of the clamping blocks 201c faces upward. At this time, the two clamping blocks 201c will release their mutual limitations, and then the two clamping frames 201a can be separated. Then the moving rod 201d is released, and the rebound force of the first spring 201f can drive the clamping block 201c to rotate back to its original position for next use. The support plate 201e is used to support the first spring 201f to prevent the first spring 201f from deviating.
[0039] Specifically, the connecting member 201 further includes a hook 201g and a support column 201h. The hook 201g is fixed to one end of the first spring 201f, and the support column 201h is fixed to the inner wall of the card frame 201a.
[0040] By hanging the hook 201g on the support column 201h, a pulling force can be applied to the first spring 201f when the movable rod 201d is moved. When the movable rod 201d is released, the rebound force of the first spring 201f can drive the clamping block 201c to rotate back to its original position for next use. The support column 201h is used to support the hook 201g to prevent the hook 201g from deviating.
[0041] Specifically, the trigger member 202 includes a trigger rod 202a and a limit block 202b. The trigger rod 202a is fixed to one side of the moving rod 201d, and the limit block 202b is arranged on one side of the trigger rod 202a.
[0042] A limiting groove corresponding to the limiting block 202b is provided on one side of the trigger rod 202a. When the moving rod 201d needs to be moved, the moving rod 201d can be driven to move by moving the trigger rod 202a. After the moving rod 201d is driven to return to its original position by the rebound force of the first spring 201f, in order to prevent the moving rod 201d from moving on its own, the limiting block 202b is moved to engage with the limiting groove on one side of the trigger rod 202a, so that the moving rod 201d can be limited, thereby preventing the moving rod 201d from moving on its own and causing the connection between the two card frames 201a to loosen.
[0043] Specifically, the trigger member 202 further includes a movable rod 202c and a slider 202d. The movable rod 202c is fixed to one side of the limit block 202b, and the slider 202d is fixed to one side of the movable rod 202c.
[0044] A movable groove corresponding to the slider 202d is provided in the card frame 201a. When it is necessary to release the limit of the trigger rod 202a, the movable rod 202c is moved. The movement of the movable rod 202c can drive the limit block 202b to separate from the limit groove, thereby releasing the limit of the trigger rod 202a. When the movable rod 202c moves, it can drive the slider 202d to slide in the movable groove, thereby supporting the movable rod 202c and preventing the movable rod 202c from deviating.
[0045] Example 3
[0046] Reference Figure 4 and Figure 5 , which is the third embodiment of the utility model, and this embodiment is based on the first two embodiments.
[0047] Specifically, the trigger member 202 further includes a pressure plate 202e, a second spring 202f and a toggle plate 202g, wherein the pressure plate 202e is fixed to one side of the slider 202d, the second spring 202f is fixed to one side of the pressure plate 202e, and the toggle plate 202g is fixed to one side of the movable rod 202c.
[0048] When the slider 202d moves, it can drive the pressure plate 202e to move. The movement of the pressure plate 202e can apply a squeezing force to the second spring 202f. The movement of the slider 202d separates the limit block 202b from the limit groove, thereby releasing the limit on the trigger rod 202a. When the trigger rod 202a needs to be limited again, the movable rod 202c is released. At this time, the rebound force of the second spring 202f can make the limit block 202b return to its original position, so as to limit the trigger rod 202a again. The setting of the toggle plate 202g is convenient for the user to move the movable rod 202c.
[0049] When in use, when it is necessary to splice two tooth blocks into the rack 104, first splice the two card frames 201a together, and by snapping the two card frames 201a together, the insert block 201b will be inserted into the slot. When the two card frames 201a are spliced together, the two snap blocks 201c will squeeze each other to make the snap blocks 201c rotate. After the card frames 201a are spliced together, the two snap blocks 201c separate and return to their original positions. At this time, the mutual limitation of the two snap blocks 201c can prevent the two card frames 201a from falling off after being spliced together, and then the limit block 202b is moved to engage with the limit groove on one side of the trigger rod 202a, so that the moving rod 201d can be limited to prevent the moving rod 201d from moving by itself and causing the connection between the two card frames 201a to loosen.
[0050] When the card frame 201a needs to be separated, the limit on the trigger rod 202a is first released, and the toggle plate 202g is moved. The movement of the toggle plate 202g can drive the movable rod 202c to move. When the movable rod 202c moves, it can drive the slider 202d to slide in the movable groove. When the slider 202d moves, it can drive the pressure plate 202e to move. The movement of the pressure plate 202e can apply a squeezing force to the second spring 202f. The movement of the slider 202d separates the limit block 202b from the limit groove, thereby releasing the limit on the trigger rod 202a. Then, the trigger When the rod 202a moves, the movement of the trigger rod 202a will drive the moving rod 201d to move. When the moving rod 201d moves, it will apply a pulling force to the first spring 201f. The movement of the moving rod 201d can drive the two clamping blocks 201c to rotate, so that the plane of the clamping block 201c faces upward. At this time, the two clamping blocks 201c will release the mutual limit, and then the two card frames 201a can be separated, and then the toggle plate 202g is released. At this time, the rebound force of the second spring 202f can make the limit block 202b return to its original position, so as to limit the trigger rod 202a again.
[0051] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
