[0036] The following achievements are examples. Although the specification refers to one or more embodiments, it does not mean that each reference relates to the same embodiment or that features are applicable only to a single embodiment. Simple features of different embodiments can also be combined to provide other embodiments.

[0037] In the following description, the terms "upper", "above", "lower", "below", "vertical", "horizontal", "top", "bottom" refer to the relative position or orientation when the door handle is assembled to the vehicle.

[0038] The present invention relates to a door handle assembly 1, which includes a bracket 3 and a movable handle 5. The bracket 3 is configured to be fixed to the door panel 4, and the movable handle 5 is configured to be fastened to the bracket 3. The bracket 3 is configured to be fixed, for example, by screws, on the inner side of the door panel. The movable handle 5 is a retractable handle, which is configured to move between the Figure 1 shown retracted position and the deployed position. In the retracted position, the handle 5 is flush with the outer side of the door panel 4. In the deployed position, the handle 5 can be grasped by the user and oriented towards as Figure 2Pulled at the open position shown. In this open position, for example in case of power shortage, the user can access the lock 7 and can introduce the key 9 into the slot of the lock 7 to manually unlock the door, as Figure 3 shown.

[0039] The vehicle door handle assembly 1 further includes a safety plate 11, also known as a Thatcham plate, which is configured to prevent access to the lock 7 from the outside of the door panel 4 with a sharp element (such as a screwdriver or other tool used by a thief). The safety plate 11 is made of a metallic material such as steel and is fastened to the bracket 3 next to the recess 6 of the bracket 3, and the recess 6 is configured to receive the lock 7. The safety plate 11 extends around the lock to prevent a thief from reaching the side of the lock with a tool such as a screwdriver.

[0040] Figure 4 An example of the safety plate 11 is shown, which has a generally square shape with three fins 13 and a central opening 15 arranged on three sides of the square so that the lock 7 can be inserted. The safety plate 11 further includes a tongue 17 configured to receive a fixing screw or a fork. The safety plate 11 further includes an opening 19 configured to receive a clamping device.

[0041] The safety plate 11 is configured to be fastened to the bracket 3, as Figure 5a and Figure 5b shown. The safety plate 11 can be clipped onto the bracket 3 or can be inserted only in the first step. The fastening of the safety plate 11 to the bracket 3 can be achieved with a fork thereafter.

[0042] The vehicle door handle assembly 1 further includes a plastic cover 21 configured to be placed above the safety plate 11 to cover the safety plate 11 and be able to hide the safety plate 11. The plastic cover 21 has a generally square shape that is at least partially complementary to the shape of the safety plate 11. The plastic cover 21 further includes a central opening 23 so that the lock 7 can be inserted. The plastic cover 21 can be clipped onto the safety plate and / or the bracket 3. In the present case, the plastic cover 21 includes a first pin and a second pin 25 that are parallel to each other and arranged in front of each other. The first pin 25 and the second pin 25 are configured to be inserted into the slot 27 of the bracket 3, as Figure 7 shown. Alternatively, the slot can be arranged in the safety plate 11. The plastic cover 21 further includes a clamping device, such as a hook 29, which is arranged on the side of the plastic cover 21 opposite to the first pin and the second pin 27 and is configured to be positioned within the opening 19 of the safety plate 11, as Figure 8 shown. Alternatively, the opening can be arranged in the bracket 3. Thus, the plastic cover 21 can be fastened to the bracket or the safety plate 11 or fastened to both by inserting the first pin and the second pin 25 into the slot 27 and by rotating the plastic cover 21 to insert the hook 29 into the opening 19, as Figure 8 shown by the arrow A in

[0043] The door handle assembly 1 further includes a lock or keyhole 7, which is configured to be introduced into a recess of the bracket 3, and the recess can be accessed via a central opening 15 of the safety plate 11 and a central opening 23 of the plastic cover 21, respectively. The lock can be restrained in place in the recess of the bracket by a fork 31 (visible in Figure 7 and Figure 8 ), and the fork 31 is configured to be displaced in a direction perpendicular to the axis of the recess, as shown by the arrow B in Figure 8 . The fork 31 can be displaced by a screw protruding through a hole in the tongue 17 so as to block the axial displacement of the safety plate 11.

[0044] After the bracket 3 is fixed to the door panel 4, the lock 7 can be positioned in the recess of the bracket 3. For this purpose, the movable handle 5 can include a manual release position, in which the movable handle 5 can be rotated enough so that the lock 7 can be introduced and positioned in the recess 6 of the bracket 3 from the outside of the door panel 4 (when the bracket 3 is fixed to the inner side of the door panel 4).

[0045] The assembly of the safety plate 11 and the plastic cover 21 to the bracket 3 can be achieved before the bracket 3 is fixed to the door panel 4. The movable handle 5 can also be fastened to the bracket 3 before the bracket 3 is fixed to the door panel 4.

[0046] The present invention also relates to a method for assembling the door handle assembly 1 as described above on a door panel including an opening.

[0047] Figure 9 The flowchart showing different steps of the method.

[0048] The first step 101 refers to positioning the safety plate 11 on the bracket 3, as shown in Figure 5a and 5b . The safety plate 11 is positioned such that its central opening 15 is in front of the recess 6, and the recess 6 is configured to receive the lock 7. The safety plate 11 can be fastened to the bracket 3, for example, by clamping or by force insertion or any other suitable fastening means.

[0049] The second step 102 refers to fastening the plastic cover 21 to the bracket 3 and / or the safety plate 11. In the current case, the plastic cover 21 is fixed to the bracket 3 on one side and to the safety plate 11 on the other side. In fact, the plastic cover 21 is first positioned in the bracket 3, especially its first pin and second pin 25 are inserted into the slots 27 of the bracket 3, as shown in Figure 7 . Then the plastic cover 21 is rotated so that its hook 29 is inserted into the opening 19 of the safety plate 11, as shown in Figure 8 .

[0050] The third step 103 refers to positioning the bracket 3 on the inner side of the door panel 4, with the movable handle 5 protruding through the opening of the door panel 4.

[0051] The fourth step 104 refers to fixing the bracket 3 on the inner side of the door panel 4. This fixing is carried out, for example, with screws.

[0052] The fifth step 105 refers to setting the movable handle 5 in the manual release position or the open position. In fact, the movable handle 5 needs to be in the open position to enable the introduction of the lock 7.

[0053] The sixth step 106 refers to introducing the lock 7 into the recess 6 of the bracket 3 through the central opening 15 of the safety plate 11 and through the central opening 23 of the plastic cover 21.

[0054] The seventh step 107 involves sliding the fork 31 with the transverse screw to limit the lock 7 in the proper position in the bracket 3. The transverse screw is also configured to pass through the hole arranged in the tongue 17 of the safety plate 11 so as to limit the safety plate 11 in the proper position on the bracket 3.

[0055] The different steps of the method can be implemented in a different order. Some steps can be implemented simultaneously, and some steps can be optional. For example, the lock 7 can be fastened to the bracket 3 before fixing the bracket 3 on the inner side of the door panel 4.

[0056] Therefore, due to the use of the plastic cover 21, the safety plate 11 is hidden, which on the one hand enables preventing burglars from knowing the exact position of the safety plate 11, and on the other hand provides a smooth and aesthetic aspect during the use of the vehicle door handle assembly 1. In fact, the plastic cover 21 can be coated with the same color as the cover of the movable handle 5 and may be coated with the same color as the door panel 4 so as to provide a uniform appearance even when the movable handle 5 is in the deployed position, while allowing the user to access the lock 7 to insert the key 9, for example, in case of power failure, thus entering his / her vehicle.
