[0038] Please also read Figures 1 to 6 Now, the back door switch installation structure and the vehicle provided by the utility model are described. The back door switch installation structure includes a lower trim panel 10, a switch assembly 20 and a locking member 30. The lower trim panel 10 is provided with a clearance hole 1011 and a first mounting hole 103. The axis of the clearance hole 1011 and the axis of the first mounting hole 103 are distributed at an angle. The switch assembly 20 includes a bracket 202 and a switch member 201 connected to the bracket 202. The top of the switch member 201 is inserted into the clearance hole 1011. The bracket 202 abuts against the bottom surface of the lower trim panel 10. The bracket 202 is provided with a second mounting hole 2024 corresponding to the first mounting hole 103. The locking member 30 is inserted into the first mounting hole 103 and the second mounting hole 2024 to fix the bracket 202 to the lower trim panel 10.

[0039] Compared with the prior art, the back door switch installation structure provided by the utility model realizes the fixing of the bracket 202 and the lower decorative plate 10 by inserting the locking member 30 into the first installation hole 103 and the second installation hole 2024, and has a simple structure and is easy to install. Moreover, compared with the installation method of the bracket 202 and the lower decorative plate 10 in the prior art, the connection is more secure. In addition, since the axis of the clearance hole 1011 and the first installation hole 103 are distributed at an angle, the locking member 30 will not protrude above the clearance hole 1011 after being inserted into the first installation hole 103 and the second installation hole 2024, thereby avoiding contact between the locking member 30 when the passenger touches the lower decorative plate 10, and ensuring the connection firmness of the locking member 30. The utility model does not need to set a flange on the top of the bracket 202 to overlap with the top of the lower decorative panel 10, so as to avoid the upper surface of the lower decorative panel 10 having a protruding part that causes it to be not smooth enough, so that the passenger can easily touch the flange when contacting the lower decorative panel 10, causing the bracket 202 to be installed loosely, and the setting may cause injuries to the passengers.

[0040] It should be noted that the top of the switch member 201 is recessed below the clearance hole 1011, or is located on the same plane or arc surface as the upper surface of the lower decorative plate 10. The top of the switch member 201 can also extend upward from the clearance hole 1011, but the height of the switch member 201 protruding from the upper surface of the lower decorative plate 10 should not be greater than 1.5 mm.

[0041] Optionally, the switch element 201 and the bracket 202 are an integral component and can be manufactured by injection molding.

[0042] Specifically, the clearance hole 1011 and the first mounting hole 103 are respectively provided on two angled plate surfaces of the lower trim plate 10. When the locking member 30 is inserted into the first mounting hole 103 and the second mounting hole 2024, it will not protrude above the clearance hole 1011, thereby preventing the passenger from contacting the locking member when opening the back door.

[0043] Preferably, the axis of the clearance hole 1011 is perpendicular to the axis of the first mounting hole 103 .

[0044] In some embodiments, see Figure 3 and Figure 6 The bracket 202 is provided with a receiving hole, the switch member 201 is inserted into the receiving hole, and the switch member 201 has a switch portion 2011 protruding upward from the receiving hole, the switch portion 2011 is inserted into the clearance hole 1011, and the top surface of the bracket 202 abuts against the lower decorative panel 10.

[0045] The switch component 201 is inserted into the receiving hole, and the inner wall of the receiving hole formed by the bracket 202 contacts the outer surface of the switch component 201, thereby increasing the contact area with the switch component 201 and improving the tightness of the connection. In addition, since the bracket 202 is installed with the lower decorative plate 10, inserting the switch component 201 in the receiving hole of the bracket 202 can also make the switch component 201 evenly stressed after being fixed, and the installation is more stable. The switch part 2011 is inserted into the clearance hole 1011, and the clearance hole 1011 limits the switch part 2011 to ensure the stability of the switch component 201, and the bracket 202 abuts against the lower decorative plate 10, thereby limiting the switch assembly 20 in the up and down directions, further increasing the firmness of the switch assembly 20 after being fixed.

[0046] Optionally, the switch element 201 and the bracket 202 are separately provided and fixed by bonding or clamping. Alternatively, they can be integrally formed.

[0047] Optionally, the locking member 30 is a threaded member, and the first mounting hole 103 is a threaded hole, and the bracket 202 is fixed to the lower trim panel 10 by screwing. The locking member 30 may also include a bolt and a nut, and the bolt is inserted into the first mounting hole 103 and the second mounting hole 2024, and screwed and locked with the bolt, so that the bracket 202 is fixed to the lower trim panel 10. The locking member 30 may also be a clamping block, and the clamping block is inserted into the first mounting hole 103 and the second mounting hole 2024 and clamped with the lower trim panel 10, so that the bracket 202 is fixed to the lower trim panel 10. It should be noted that although the clamping block is clamped with the lower trim panel 10, the clamping block is an external connecting member of the bracket 202, and there is no need to set a flange on the bracket 202, and the insertion direction of the clamping block is not limited to the up and down direction, so the bracket 202 does not need to protrude upward from the lower trim panel 10, which can ensure that the upper surface of the lower trim panel 10 is smooth and fluent.

[0048] In some embodiments, see Figure 3 to Figure 4 The bracket 202 includes a supporting body 2021 and a plurality of mounting pieces 2022, and the accommodating hole is opened in the supporting body 2021; the plurality of mounting pieces 2022 are respectively arranged on both sides of the supporting body 2021 along the left and right directions, and the second mounting hole 2024 is opened in the mounting piece 2022, and the axis of the second mounting hole 2024 is perpendicular to the making way hole 1011.

[0049] The top of the support body 2021 abuts against the bottom of the lower trim panel 10, and the support body 2021 is limited in the up and down direction, and the locking member 30 is inserted into the first mounting hole 103 and the second mounting hole 2024 to fix the mounting piece 2022 to the lower trim panel 10. Since the axis of the second mounting hole 2024 is perpendicular to the axis of the clearance hole 1011, the problem of the locking member 30 protruding upward from the surface of the lower trim panel 10 is avoided, and the mounting piece 2022 can also be limited in a direction perpendicular to the upward direction, thereby increasing the connection firmness between the bracket 202 and the lower trim panel 10.

[0050] It should be noted that the clearance hole 1011 is opened in the up-down direction, the second mounting hole 2024 and the first mounting hole 103 are both opened in the front-to-back direction, and the mounting piece 2022 contacts the lower trim panel 10 in the front-to-back direction, thereby limiting the mounting piece 2022 in the front-to-back direction.

[0051] In some embodiments, see Figure 4 The lower decorative panel 10 includes a decorative panel body 101 and a clip 105, and a clearance hole 1011 is opened in the decorative panel body 101; the clip 105 is located on the left or right side of the clearance hole 1011; the bracket 202 has an elastic card 2023 corresponding to the clip 105, and the elastic card 2023 is clipped and matched with the clip 105.

[0052] When installing the switch assembly 20, first engage the elastic card 2023 with the card connector 105 to achieve pre-installation. The pre-installation not only preliminarily fixes the switch assembly 20 to the lower decorative panel 10, but also aligns the first mounting hole 103 and the second mounting hole 2024. There is no need for positioning during installation, which improves installation efficiency. After the pre-installation is completed, the locking member 30 is inserted into the first mounting hole 103 and the second mounting hole 2024 to further fix the bracket 202 and the decorative panel body 101. This embodiment achieves fixation through the scheme of engaging the elastic card 2023 with the card connector 105 and the scheme of inserting the locking member 30 into the first mounting hole 103 and the second mounting hole 2024, which increases the stability and firmness of the bracket 202 and the lower decorative panel 10 after installation.

[0053] It should be noted that the elastic card 2023 is located on the left or right side of the second mounting hole 2024 and does not interfere with the second mounting hole 2024 .

[0054] In some embodiments, see Figure 6 The elastic card 2023 has a clamping platform 2025 protruding outward, and the clamping platform 2025 is clamped and matched with the clamping piece 105.

[0055] The clamping platform 2025 is clamped and matched with the clamping piece 105 to fix the bracket 202. The structure is simple and the operation is convenient. When the bracket 202 needs to be disassembled, the elastic card 2023 is squeezed to separate the clamping platform 2025 from the clamping piece 105.

[0056] In some embodiments, see Figure 5 The lower decorative plate 10 also includes a mounting member 102 connected to the decorative plate body 101 , a first mounting hole 103 is opened in the mounting member 102 , and the bracket 202 abuts against the mounting member 102 .

[0057] The mounting member 102 is in contact with the bracket 202, and while limiting the position of the bracket 202, a separation space is formed between the bracket 202 and the decorative plate 101 bracket 202. When the back door is opened or closed, a force is generated on the switch assembly 20, and the separation space can provide a deformation space for the bracket 202 to avoid the bracket 202 from interfering with the decorative plate 101 and causing damage after being subjected to force. Compared with the solution of opening the first mounting hole 103 in the decorative plate 101, this embodiment increases the axial depth of the first mounting hole 103, which not only increases the contact area with the locking member 30 and improves the fastening of the connection, but also avoids the risk of the locking member 30 being broken due to the high pressure after being subjected to force. In addition, the first mounting hole 103 is opened in the mounting member 102, and the first mounting hole 103 can also be set as a threaded hole, and the locking member 30 is screwed with the threaded hole, without the need to set a nut separately, and also avoids the problem of the locking member 30 passing through the first mounting hole 103, thereby reducing the occupied space.

[0058] In some embodiments, see Figures 4 to 5 The mounting member 102 includes a mounting column 1021 and a plurality of supporting plates 1022 . The mounting column 1021 is connected to the decorative plate body 101 . The first mounting hole 103 is opened in the mounting column 1021 . The plurality of supporting plates 1022 are radially distributed on the outer peripheral surface of the mounting column 1021 and connected to the decorative plate body 101 .

[0059] The support sheet 1022 can increase the contact area with the decorative plate body 101 and increase the connection tightness of the mounting member 102. Moreover, the support sheet 1022 and the mounting column 1021 abut against the mounting sheet 2022, reducing the pressure of the mounting sheet 2022 and preventing the mounting sheet 2022 from breaking or being damaged.

[0060] In some embodiments, see Figures 4 to 5 The mounting member 102 further includes a reinforcing sheet 106 disposed on the outer circumferential surface of the mounting column 1021 , and the reinforcing sheet 106 is connected to the decorative plate body 101 along the radial direction of the mounting column 1021 .

[0061] The reinforcing sheet 106 provides support for the mounting column 1021 and the decorative panel 101 , thereby ensuring that the position between the mounting column 1021 and the decorative panel 101 is relatively stable, and reducing the probability of deformation of the mounting column 1021 after being subjected to force.

[0062] In some embodiments, see Figure 1 The lower trim panel 10 also includes a guide member 104 connected to the outer peripheral surface of the mounting column 1021. The guide member 104 includes a connecting portion and a guide portion arranged at an angle to the connecting portion. The connecting portion is connected to the outer peripheral surface of the mounting column 1021. The guide portion is bent upward from the connecting portion and is engaged with the elastic card 2023.

[0063] The switch assembly 20 is inserted into the clearance hole 1011 from bottom to top, and the guide portion is bent upward toward the top of the connecting portion. During the upward movement of the switch assembly 20, the elastic card 2023 gradually increases the contact area with the guide portion, and the elastic card 2023 is gradually squeezed until the clamping piece 105 is clamped with the elastic card 2023, thereby fixing the bracket 202.

[0064] Optionally, the included angle between the clamping portion and the connecting portion is an obtuse angle.

[0065] In some embodiments, see Figure 3 to Figure 4 The lower decorative plate 10 also includes a reinforcing flange 107 arranged around the outer periphery of the clearance hole 1011 . The reinforcing flange 107 is connected to the bottom of the decorative plate body 101 and abuts against the bracket 202 .

[0066] The strength of the area where the clearance hole 1011 is opened in the decorative plate body 101 is lower than that of other areas, which makes it easy to deform around the clearance hole 1011. The reinforcement flange 107 is arranged on the periphery of the clearance hole 1011 to increase the strength of the area around the clearance hole 1011 and reduce the probability of deformation. In addition, the bracket 202 abuts against the reinforcement flange 107 to limit the position of the bracket 202, and the bracket 202 and the decorative plate body 101 form a gap in the vertical direction to provide deformation space for the bracket 202.

[0067] Based on the same inventive concept, the utility model also provides a vehicle, which includes the above-mentioned back door switch installation structure.

[0068] The vehicle provided by the utility model adopts the above-mentioned tailgate switch installation structure, and the bracket 202 is fixed to the lower trim panel 10 by inserting the locking member 30 into the first installation hole 103 and the second installation hole 2024. The structure is simple, the installation is convenient, and the connection is more secure than the installation method of the bracket 202 and the lower trim panel 10 in the prior art. In addition, since the axes of the clearance hole 1011 and the first installation hole 103 are distributed at an angle, the locking member 30 will not protrude above the clearance hole 1011 after being inserted into the first installation hole 103 and the second installation hole 2024, thereby avoiding contact between the locking member 30 and the lower trim panel 10 when the passenger touches the locking member 30, and ensuring the connection firmness of the locking member 30. The utility model does not need to set a flange on the top of the bracket 202 to overlap with the top of the lower decorative panel 10, so as to avoid the upper surface of the lower decorative panel 10 having a protruding part that causes it to be not smooth enough, so that the passenger can easily touch the flange when contacting the lower decorative panel 10, causing the bracket 202 to be installed loosely, and the setting may cause injuries to the passengers.

[0069] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
