[0032] The present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the technical features involved in the various embodiments of the present application described below can be combined with each other as long as they do not conflict with each other. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be understood as limiting the present application.

[0033] Combination Figures 1 to 6 As shown, this embodiment provides a fixed mounting frame of a wire displacement sensor 21, which is used to fix the wire displacement sensor 21. In this embodiment, the wire displacement sensor 21 can be detachably connected to the fixed mounting frame, so that the wire displacement sensor 21 can be disassembled for replacement and maintenance.

[0034] Combination Figure 1 As shown, the fixed mounting frame includes a main body 11. For example, when the wire displacement sensor 21 needs to perform measurement, the main body 11 is connected to the lower guard plate 31 of the vehicle instrument panel.

[0035] Combination Figure 1 , Figure 3 and Figure 4 As shown, the fixed mounting frame further includes a movable portion 12 , the movable portion 12 has a hinged end and a movable end that are spaced apart from each other, and the hinged end of the movable portion 12 is hinged to the main body 11 .

[0036] It should be understood that, since the hinged end of the movable portion 12 is hinged to the main body 11 , the movable portion 12 can rotate relative to the main body 11 to change the angle of the movable portion 12 relative to the main body 11 .

[0037] Combination Figure 1 and Figure 4 As shown, the fixed mounting frame also includes an angle adjustment portion 13, the angle adjustment portion 13 has a rotating end and a free end that are spaced apart from each other, the rotating end of the angle adjustment portion 13 is hinged to the main body 11, and the angle adjustment portion 13 has a first fastening state and a first adjustment state that can be switched with respect to the movable portion 12. When the angle adjustment portion 13 is in the first fastening state, the free end of the angle adjustment portion 13 is locked with the movable end of the movable portion 12; when the angle adjustment portion 13 is in the first adjustment state, the movable portion 12 can rotate relative to the main body 11 along a first direction to adjust the angle value of the movable portion 12 relative to the main body 11.

[0038] In this embodiment, the first direction is a clockwise or counterclockwise direction with the hinge between the movable portion 12 and the main body 11 as the center.

[0039] It should be understood that, when the angle adjustment portion 13 is in the first fastening state, its free end is locked with the movable end of the movable portion 12; when it is in the first adjustment state, the movable portion 12 can rotate relative to the main body 11 along the first direction. Therefore, when the movable portion 12 needs to adjust the angle relative to the main body 11 along the first direction, the angle adjustment portion 13 can be switched to the first adjustment state. After the movable portion 12 completes the angle adjustment relative to the main body 11, the angle adjustment portion 13 can be switched to the first fastening state, thereby allowing the movable portion 12 to maintain the adjusted angle.

[0040] Combination Figures 2 to 4 As shown, the fixed mounting frame also includes a mounting portion 14, which is used to install the pull-wire displacement sensor 21. The mounting portion 14 has a second fastening state and a second adjustment state that can be switched with each other. When the mounting portion 14 is in the second adjustment state, the mounting portion 14 can move relative to the movable portion 12 along a second direction, and the second direction intersects with the first direction; when the mounting portion 14 is in the second fastening state, the mounting portion 14 is fastened to the movable portion 12.

[0041] It should be understood that, since the mounting portion 14 can move relative to the movable portion 12 along a second direction intersecting the first direction when the mounting portion 14 is in the second adjustment state, and the mounting portion 14 is fastened to the movable portion 12 when the mounting portion 14 is in the second fastening state, when the mounting portion 14 needs to change its position relative to the movable portion 12, the mounting portion 14 can be switched to the second adjustment state. After the mounting portion 14 completes the change of its position relative to the movable portion 12, the mounting portion 14 can be switched to the second fastening state, thereby allowing the mounting portion 14 to maintain the adjusted position.

[0042] Combination Figure 1 and Figure 3 As shown, the angle adjustment portion 13 includes a first fastener 132 and an angle adjustment member 131, the angle adjustment member 131 has a rotating end and a free end that are relatively arranged, and the first fastener 132 has a first fastening state and a first adjustment state; when the first fastener 132 is in the first adjustment state, the movable end of the movable portion 12 can rotate relative to the main body 11 along the first direction; when the first fastener 132 is in the first fastening state, the first fastener 132 is inserted into the angle adjustment member 131 and the movable portion 12 to lock the free end of the angle adjustment member 131 with the movable end of the movable portion 12.

[0043] In this embodiment, the angle adjustment member 131 is a rectangular plate, and the rotating end and the free end are arranged opposite to each other along the length direction of the angle adjustment member 131 .

[0044] Of course, in other embodiments, the angle adjustment member 131 may also be in other shapes, which is not limited here.

[0045] In this embodiment, the first fastener 132 is a countersunk bolt, and a threaded hole is provided on the side of the movable portion 12. The countersunk bolt is used to be inserted into the angle adjustment portion 13 and then inserted into the threaded hole. The depth of the first fastener 132 inserted into the threaded hole when it is in the first adjustment state is shallower than the depth of the first fastener 132 inserted into the threaded hole when it is in the first fastening state; that is, during the process of the first fastener 132 switching from the first adjustment state to the first fastening state, the first fastener 132 gradually penetrates into the threaded hole; during the process of the first fastener 132 switching from the first fastening state to the first adjustment state, the first fastener 132 gradually withdraws from the threaded hole.

[0046] Of course, in other embodiments, the first fastener 132 may also be other structures, such as a snap-fit ​​structure arranged at intervals, wherein the snap-fit ​​structure includes a snap-fit ​​groove and a snap-fit ​​block which are arranged one by one on the side surface of the movable portion 12 and the angle adjustment portion 13 .

[0047] It should be understood that the provision of the first fastener 132 not only enables the movable end of the movable part 12 to be rotated along the first direction relative to the main body 11, thereby fastening the angle adjustment member 131 to the movable end of the movable part 12, so that neither the movable part 12 nor the angle adjustment member 131 can move; it also enables the movable part 12 to quickly switch from the first fastening state to the first adjustment state when the angle adjustment is required, thereby facilitating the angle adjustment of the movable part 12.

[0048] Furthermore, combined with Figure 1 and Figure 3 As shown, the angle adjustment member 131 is provided with a first guide hole 101; when the first fastener 132 is in the first adjustment state, the first fastener 132 is arranged in the first guide hole 101, and can reciprocate along the hole wall of the first guide hole 101 between the rotating end and the free end of the angle adjustment member 131; when the first fastener 132 is in the first fastening state, the first fastener 132 is penetrated through the first guide hole 101 and the movable part 12.

[0049] In this embodiment, the first guide hole 101 is an elongated hole, and a length direction thereof is parallel to a length direction of the angle adjustment member 131 .

[0050] It should be understood that when the angle adjustment member 131 is provided with a first guide hole 101, on the one hand, after the first fastener 132 is inserted into the first guide hole 101, the displacement of the first fastener 132 can be guided and limited by the hole wall of the first guide hole 101, so as to facilitate the angle adjustment of the movable part 12, and on the other hand, it can also reduce the weight of the angle adjustment member 131.

[0051] Combination Figure 2 and Figure 3 As shown, the mounting portion 14 includes a mounting member 141 and a second fastener 142, and the second fastener 142 has a second fastening state and a second adjustment state; when the second fastener 142 is in the second adjustment state, the mounting member 141 can move along the second direction relative to the movable portion 12; when the second fastener 142 is in the second fastening state, the second fastener 142 is inserted into the movable portion 12 and the mounting member 141 to fasten the mounting member 141 to the movable portion 12.

[0052] In this embodiment, the mounting member 141 and the movable portion 12 are both rectangular plates, the width of the mounting member 141 is smaller than the width of the movable portion 12, and the mounting member 141 is stacked on one side of the movable portion 12 along the thickness direction of the movable portion 12 and is parallel to the movable portion 12. The second direction is the width direction of the movable portion 12.

[0053] Of course, in other embodiments, the second direction may also be the length direction of the movable portion 12; or any other direction intersecting with the first direction. That is to say, when the second direction is any other direction intersecting with the first direction, the mounting member 141 can not only move horizontally or vertically relative to the movable portion 12, but also make the mounting member 141 move irregularly such as in an arc shape relative to the movable portion 12. The specific configuration can be made according to actual needs and will not be described in detail here.

[0054] In this embodiment, the second fastener 142 is a countersunk bolt, and a threaded hole is provided on the plate surface of the mounting member 141. The countersunk bolt is used to be inserted into the movable portion 12 and then inserted into the threaded hole. The depth of the second fastener 142 inserted into the threaded hole when it is in the second adjustment state is shallower than the depth of the second fastener 142 inserted into the threaded hole when it is in the second fastening state; that is, during the process of the second fastener 142 switching from the second adjustment state to the second fastening state, the second fastener 142 gradually penetrates into the threaded hole; during the process of the second fastener 142 switching from the second fastening state to the second adjustment state, the second fastener 142 gradually withdraws from the threaded hole.

[0055] Of course, in other embodiments, the second fastener 142 may also be other structures, such as a snap-fit ​​structure arranged at intervals, wherein the snap-fit ​​structure includes a snap-fit ​​groove and a snap-fit ​​block arranged on the movable portion 12 and the mounting member 141 in a one-to-one correspondence.

[0056] It should be understood that the provision of the second fastener 142 not only enables the mounting member 141 to be fastened to the movable portion 12 after the mounting member 141 moves relative to the movable portion 12 along the second direction, so that the mounting member 141 cannot move relative to the movable portion 12; it also enables the mounting member 141 to be quickly switched from the second fastening state to the second adjustment state when the position of the mounting member 141 needs to be adjusted along the second direction, thereby facilitating the position adjustment of the mounting member 141 along the second direction.

[0057] Furthermore, combined with Figures 1 to 6 As shown, the movable portion 12 is provided with a second guide hole 102; when the second fastener 142 is in the second adjustment state, the second fastener 142 is arranged in the second guide hole 102, and can reciprocate along the hole wall of the second guide hole 102 in the second direction; when the second fastener 142 is in the second fastening state, the second fastener 142 is passed through the second guide hole 102 and the mounting member 141.

[0058] In this embodiment, the second guide hole 102 is an elongated hole, and the length direction of the second guide hole 102 is parallel to the width direction of the movable portion 12 .

[0059] It should be understood that when the movable part 12 is provided with the first guide hole 101, on the one hand, after the second fastener 142 is inserted into the second guide hole 102, the displacement of the second fastener 142 can be guided and limited by the hole wall of the second guide hole 102, so as to facilitate the position adjustment of the mounting part 141 along the second direction. On the other hand, it can also reduce the weight of the movable part 12.

[0060] In this embodiment, the movable part 12 is provided with two second guide holes 102, and the two second guide holes 102 are arranged at intervals from each other along the hinged end of the movable part 12 in the direction of the movable end; the fixed mounting frame includes two second fasteners 142, and the two second fasteners 142 in the second adjustment state can move back and forth along the hole wall of the second guide hole 102 in the second direction, and the two second fasteners 142 in the second fastening state can be correspondingly penetrated through the second guide hole 102 and the mounting member 141 to fasten the mounting member 141 to the movable part 12.

[0061] It should be understood that the two second guide holes 102 are respectively located on both sides of the length direction of the movable part 12. When the mounting member 141 is stacked on one side of the movable part 12 along the thickness direction of the movable part 12 and is parallel to the movable part 12, and then the two second fasteners 142 are passed through the two second guide holes 102 and the mounting member 141 in a one-to-one correspondence, on the one hand, when the second fasteners 142 are in the second adjustment state, the mounting member 141 can move smoothly along the second direction; on the other hand, when the second fasteners 142 are in the second fastening state, the mounting member 141 and the movable part 12 can be fastened more stably.

[0062] Combination Figure 2 and Figure 5 As shown, the movable part 12 includes a back side and a front side which are arranged relatively to each other along a first direction. The back side of the movable part 12 is closer to the main body 11 than the front side of the movable part 12. The movable part 12 is provided with an installation window 103. The installation window 103 and the second guide hole 102 are arranged at intervals from each other and both penetrate from the front side to the back side. The mounting member 141 is provided with a mounting structure 143. The mounting member 141 is arranged on the back side of the movable part 12, and the mounting structure 143 is arranged corresponding to the installation window 103.

[0063] In this embodiment, the two second guide holes 102 are respectively located on both sides of the installation window 103 along the length direction of the movable part 12, and the length of the installation member 141 is greater than the size of the installation window 103 along the length direction of the movable part 12, so that the installation member 141 has overlapping parts on both opposite sides of the installation window 103 along the length direction of the movable part 12, so that the two second fasteners 142 can be inserted into the installation member 141.

[0064] It should be understood that the combination Figure 1 and Figure 3 As shown, the mounting member 141 is provided on the back of the movable part 12, and the length of the mounting member 141 is greater than the dimension of the mounting window 103 along the length direction of the movable part 12, so that the mounting member 141 has overlapping parts on both opposite sides of the mounting window 103 along the length direction of the movable part 12. After the wire displacement sensor 21 is installed on the mounting structure 143 exposed in the mounting window 103, if the wire displacement sensor 21 is subjected to a pulling force along the thickness direction of the mounting member 141, the back of the movable part 12 can limit the mounting member 141. At the same time, after the movable part 12 is provided with the mounting window 103, it can also play a role in reducing weight.

[0065] Combination Figures 1 to 4 as well as Figure 6 As shown, the fixed mounting frame also includes a first fixed claw 15 and a second fixed claw 16, and the first fixed claw 15 and the second fixed claw 16 are arranged on two opposite sides of the main body 11, and can be extended and retracted relative to the main body 11. For example, the first fixed claw 15 can be extended and retracted correspondingly relative to the upper side of the main body 11, and the second fixed claw 16 can be extended and retracted correspondingly relative to the lower side of the main body 11. In this embodiment, the first fixed claw 15 can be extended and retracted correspondingly relative to the upper side of the main body 11, and the second fixed claw 16 can always remain in a fixed state, that is, the second fixed claw 16 is fixedly connected to the main body 11.

[0066] It should be understood that after the first fixed claw 15 can be extended and retracted relative to the main body 11, when the main body 11 is connected to the vehicle dashboard lower guard plate 31, the first fixed claw 15 can be extended or shortened to adapt to the length or width of the vehicle dashboard lower guard plate 31, so as to adapt to the size of the vehicle dashboard lower guard plate 31 when the main body 11 is connected to the vehicle dashboard lower guard plate 31, thereby ensuring that the first fixed claw 15 and the second fixed claw 16 can firmly grasp the vehicle dashboard lower guard plate 31.

[0067] Combination Figure 2 as well as Figure 6 As shown, the main body 11 is provided with a through slot 104, and the through slot 104 includes a first opening and a second opening arranged opposite to each other. In this embodiment, the through slot 104 extends along the length direction of the main body 11, and penetrates through two opposite side surfaces of the main body 11 along the length direction of the main body 11, so as to form the first opening and the second opening in a one-to-one correspondence.

[0068] Accordingly, combined Figure 6As shown, the first fixed claw 15 includes a first connecting portion 151 and a first claw portion 152, and the second fixed claw 16 includes a second connecting portion 161 and a second claw portion 162. One end of the first connecting portion 151 is connected to the first claw portion 152, and the other end of the first connecting portion 151 is inserted into the first opening and can slide along the groove wall of the through groove 104 in the through groove 104; one end of the second connecting portion 161 is connected to the second claw portion 162, and the other end of the second connecting portion 161 is inserted into the second opening.

[0069] In this embodiment, the through groove 104 is a stepped groove, that is, the cross section of the through groove 104 is a "T"-shaped through groove 104 in which the cross section area of ​​the top groove portion is larger than the cross section area of ​​the bottom groove portion. Accordingly, the first connecting portion 151 and the second connecting portion 161 both include a boss a and a connecting rod b, and the boss a and the corresponding first claw portion 152 or second claw portion 162 are connected to the two ends of the connecting rod b along the axial direction of the connecting rod b in a one-to-one correspondence, wherein the cross section of the boss a matches the cross section of the through groove 104, so that when the boss a of the first connecting portion 151 is inserted into the through groove 104, on the one hand, the first connecting portion 151 can slide smoothly in the through groove 104, and on the other hand, the first connecting portion 151 can not be displaced from the top groove portion to the bottom groove portion in the through groove 104. The cross-sectional area of ​​the first claw portion 152 is larger than the cross-sectional area of ​​the through slot 104 , so that when the boss a of the first connecting portion 151 is inserted into the through slot 104 , the first claw portion 152 will not shrink into the through slot 104 .
