Description

Technical Field

[0001] The utility model relates to the technical field of installation tools, in particular to an inner rearview mirror installation tool. Background Art

[0002] An automotive inner rearview mirror is installed by connecting a rearview mirror arm to a mirror arm seat located inside the front windshield. When installing an automotive inner rearview mirror, the connection between the rearview mirror arm and the mirror arm seat is laborious, time-consuming and inefficient. Due to the complex operation environment and limited space, the operator directly grabs the rearview mirror arm by hand and applies force to the rearview mirror arm while also paying attention to surrounding components including the inner rearview mirror decorative cover, wiring harness, camera, etc., to prevent hand scratches or damage to surrounding components. Therefore, automotive OEMs choose a special installation tool that matches the rearview mirror arm for auxiliary installation. Summary of the Utility Model

[0003] In view of this, the utility model provides an inner rearview mirror installation tool suitable for installing an automotive inner rearview mirror and capable of forming a reliable docking adaptation with the rearview mirror arm.

[0004] The inner rearview mirror installation tool of the utility model includes a manipulation part, a docking part and a limiting part. The manipulation part and the docking part are connected as a whole. The docking part is provided with a limiting jack for communicating with the bottom slot of the rearview mirror arm. The limiting part includes a limiting plug detachably inserted into the limiting jack, and the hole wall of the limiting jack includes an anti-disengagement wall, and the anti-disengagement wall at least extends to one side of the limiting plug close to the end of the docking part. The end of the docking part is used to face a mirror arm seat adapted to the top of the rearview mirror arm.

[0005] The beneficial effect of the inner rearview mirror installation tool of the utility model lies in that: when the docking part is docked and adapted to the bottom end of the rearview mirror arm, and the limiting plug is inserted into the limiting jack and extends into the bottom slot of the rearview mirror arm, even if the bottom end of the rearview mirror arm has a tendency to break away from the docking part under the action of an external force, due to the blocking effect of the anti-disengagement wall on one side of the limiting plug close to the end of the docking part, it is not easy to cause the limiting plug to be carried by the bottom end of the rearview mirror arm and thus disengage from the limiting jack along the direction of approaching and squeezing the end of the docking part, ensuring that the limiting plug is firmly held in the limiting jack, thereby ensuring that the docking part and the bottom end of the rearview mirror arm form a reliable docking adaptation, and ultimately ensuring that the force applied by the operator to the manipulation part is efficiently and fully transmitted to the rearview mirror arm through the docking part to improve the connection success rate between the rearview mirror arm and the mirror arm seat.

[0006] In some embodiments, the docking part is further provided with a docking groove communicating with the limiting jack. The docking groove is used to accommodate the bottom end of the rearview mirror arm, and the anti-disengagement wall at least extends to one side of the limiting plug away from the bottom of the docking groove.

[0007] In some embodiments, the docking part includes a base plate and a side plate. The operating part and the side plate are respectively connected to opposite sides of the base plate. The base plate is used to form the bottom of the docking groove and surrounds the side plate to form the docking groove. The limiting insertion hole is opened in the side plate.

[0008] In some implementations, the wall of the limiting socket is closed along the circumference of the limiting plug.

[0009] In some implementations, the opening shape of the limiting socket is an equilateral triangle, which is the same as the cross-sectional shape of the limiting plug.

[0010] In some embodiments, the wall of the limiting insertion hole includes a first anti-rotation wall and a second anti-rotation wall arranged at an included angle, and the outer peripheral wall of the limiting plug includes a first mating wall and a second mating wall arranged at an included angle, the first mating wall and the second mating wall respectively adapting to the first anti-rotation wall and the second anti-rotation wall.

[0011] In some embodiments, the first anti-rotation wall and the second anti-rotation wall form an anti-detachment wall.

[0012] In some embodiments, the first anti-rotation wall and the second anti-rotation wall form an anti-rotation angle with the opening direction opposite to the end of the mating part, and the first mating wall and the second mating wall form an anti-rotation protrusion, which extends along the length direction of the limiting plug.

[0013] In some embodiments, a protective layer is further included on the mating portion, the protective layer being used to adhere to and separate the surface of the mating portion from the surface of the bottom end of the rearview mirror arm; and / or,

[0014] It also includes an anti-slip rope, one end of which is connected to at least one of the control unit and the docking unit, and the other end is connected to a limit plug.

[0015] In some embodiments, the docking part is also provided with a docking groove and a disassembly side hole that connects to the docking groove. When the bottom end of the rearview mirror arm extends into the docking groove, a disassembly gap extending to the disassembly side hole is formed between the bottom end of the rearview mirror arm and the inner wall of the docking groove.

Detailed Implementation

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] See Figures 1-2 This utility model provides an interior rearview mirror installation tool suitable for connecting an interior rearview mirror to a mirror arm holder located inside the windshield. The interior rearview mirror installation tool includes an operating part 10 and a docking part 20 connected as one unit. The operating part 10 can be held by the operator and serves as the part where the operator applies the force required for installation. The docking part 20 is used to dock and adapt with the bottom end of the rearview mirror arm 40.

[0025] The top end of the rearview mirror arm 40 serves as the mounting end 43 for connecting the rearview mirror arm 40 to the arm holder, while the bottom end of the rearview mirror arm 40 serves as the docking end 41 for fixed engagement with the docking part 20. The docking end 41 is also provided with a ball head 42 for rotatably connecting with the rearview mirror body. The force exerted by the operator on the operating part 10 is transmitted to the rearview mirror arm 40 through the docking part 20, so that the mounting end 43 and the arm holder are connected by means of screwing, pressing, etc.

[0026] See Figures 2-3 In some embodiments, the docking part 20 has a docking groove 23 for accommodating the docking end 41. The inner wall shape of the docking groove 23 matches the shape of the surface of the docking end 41. The docking end 41 extends into the docking groove 23 and forms a fixed fit with the inner wall of the docking groove 23.

[0027] Specifically, see Figures 2-3 The docking part 20 includes a base plate 21 and at least two side plates 22. The operating part 10 includes a rod 12 and a gripping part 11. One end of the rod 12 is connected to one side of the base plate 21, and the side plates 22 are connected to the other side of the base plate 21. The gripping part 11 is connected to the end of the rod 12 that is relatively away from the base plate 21. The base plate 21 and the multiple side plates 22 together form a docking groove 23. The side of the base plate 21 facing away from the operating part 10 forms the bottom of the docking groove 23, and the ends of the multiple side plates 22 that are away from the base plate 21 form the openings of the docking groove 23. The docking end 41 can pass through the opening of the docking groove 23 and approach the base plate 21 to extend into the docking groove 23, and can also move away from the base plate 21 and pass through the opening of the docking groove 23 to withdraw from the docking groove 23.

[0028] It is understandable that the ends of the multiple side plates 22 away from the bottom plate 21 also form the ends of the docking portions 20. When the bottom end of the rearview mirror arm 40 forming the docking end 41 is fixedly installed in the docking groove 23, and the top end of the rearview mirror arm 40 forming the bracket connection end 43 and the arm bracket approach each other and are about to complete the connection, the ends of the docking portions 20 are facing the arm bracket. In other embodiments, the docking groove 23 can be omitted. For example, the docking portion 20 includes a supporting portion and a docking protrusion. The supporting portion is used to fix and abut against the surface of the docking end 41. The docking protrusion protrudes outward relative to the supporting portion and extends into the docking end 41. A limiting step surface that matches the docking end 41 is formed between the supporting portion and the docking protrusion. The ends of the docking portions 20 can be formed on the top end of the docking protrusion that is farthest from the supporting portion.

[0029] Optionally, in some embodiments, the interior rearview mirror installation tool further includes a protective layer disposed on the mating portion 20. The protective layer is used to adhere to the respective surfaces of the mating portion 20 and the mating end 41 and to separate the mating portion 20 and the mating end 41, thereby preventing direct contact between the mating portion 20 and the mating end 41 and thus avoiding wear on the mating end 41. Preferably, the protective layer can be a soft non-woven fabric disposed on the inner wall of the mating groove 23.

[0030] See Figure 3 See also Figures 4-5, in some embodiments, the docking portion 20 is further provided with a disassembly side hole 26 communicating with the docking groove 23. The disassembly side hole 26 is formed between the end of the docking portion 20 and one side of the connecting rod portion 12 of the docking portion 20. The disassembly side hole 26 is used for external tools such as a pry bar, a screwdriver, and a crowbar to extend into the docking groove 23. When the docking end 41 extends into the docking groove 23 and is fixedly fitted with the inner wall of the docking groove 23, a disassembly gap is formed between the surface of the docking end 41 located in the docking groove 23 and the inner wall of the docking groove 23, and the disassembly gap extends to the disassembly side hole 26.

[0031] With this arrangement, an operator can use external tools such as a pry bar, a screwdriver, and a crowbar to pry the docking end 41 in the docking groove 23, so that the docking end 41 and the docking portion 20 are separated. After the connection between the card seat connection end 43 and the mirror arm card seat is completed, the operator can insert the above external tool into the disassembly gap through the disassembly side hole 26, and then apply force to the above external tool to pry the docking end 41 to disengage the docking end 41 from the docking portion 20, avoiding directly pulling the operating portion 10 to cause the separation or connection failure of the card seat connection end 43 and the mirror arm card seat.

[0032] Forming a reliable fixed fit between the docking end 41 and the docking portion 20 and restricting the relative movement of the docking end 41 and the docking portion 20 after the mating connection is an important guarantee for completing the installation operation of the automotive interior rearview mirror using the interior rearview mirror installation tool. In view of this, the automotive interior rearview mirror配套 with the interior rearview mirror installation tool of the present invention has a bottom slot 411 opened at the docking end 41. The interior rearview mirror installation tool of the present invention further includes a limiting portion 30. The docking portion 20 is further provided with a limiting jack 24 for communicating with the bottom slot 411. The docking portion 20 includes a limiting plug 31 detachably inserted into the limiting jack 24. Refer to Figure 2 、 Figures 4-5 , when the docking end 41 and the docking portion 20 are fixedly mated, the limiting jack 24 communicates with the bottom slot 411. At this time, the limiting plug 31 can pass through the limiting jack 24 and extend into the bottom slot 411.

[0033] In this way, the limiting plug 31 penetrates through the docking end 41 and the docking portion 20 together when the docking end 41 and the docking portion 20 are fixedly mated, thereby restricting the degree of freedom of movement of the docking end 41 and the docking portion 20 from separating from each other, and avoiding the situation that the force applied by the operator to the operating portion 10 cannot be transmitted to the rearview mirror arm 40 due to the separation of the docking end 41 and the docking portion 20. After the connection between the card seat connection end 43 and the mirror arm card seat is completed, the operator first withdraws the limiting plug 31 from the bottom slot 411 and the limiting jack 24, and then can perform the disassembly of the docking end 41 and the docking portion 20.

[0034] Optionally, refer to Figures 1-2In some embodiments, the limiting plug 31 is a limiting pin, and the bottom slot 411 and the limiting hole 24 are respectively a pin groove and a pin hole for the limiting pin to be inserted and removed. In order to prevent the limiting pin from being lost, the interior rearview mirror installation tool also includes an anti-detachment rope 32, one end of which is connected to at least one of the operating part 10 and the docking part 20, and the other end of which is connected to the limiting pin.

[0035] See Figure 2 and Figure 3 See also Figures 4-5 This utility model further specifies that the wall of the limiting insertion hole 24 includes an anti-disengagement wall 25, which extends at least to the side of the limiting plug 31 relatively close to the end of the docking portion 20. As mentioned above, the end of the docking portion 20 is used to face the arm holder that is adapted to the top of the rearview mirror arm 40. Specifically, the limiting plug 31 is located between the bottom end and the end of the docking portion 20 in the height direction of the docking portion 20. The bottom end of the docking portion 20 is connected to the operating part 10 and is disposed opposite to the arm holder. Figures 1-5 In the embodiment shown, the bottom end of the docking part 20 is the side of the base plate 21 that is away from the side plate 22. The end of the docking part 20 is formed by the ends of multiple side plates 22 that are relatively far away from the base plate 21. The opening of the docking groove 23 is formed at the end of the docking part 20. The side of the limiting plug 31 that is relatively close to the end of the docking part 20 is the area on the outer periphery of the limiting pin that is close to the end of the docking part 20 and far away from the base plate 21.

[0036] This design significantly improves the reliability of the mating fit between the rearview mirror installation tool and the rearview mirror arm 40. With the mating part 20 and mating end 41 fixedly fitted, and the limiting plug 31 inserted into the limiting socket 24 and extending into the bottom slot 411, even if the rearview mirror arm 40 tends to detach from the mating part 20 under external force, the anti-detachment wall 25 prevents the limiting plug 31 from being driven by the mating end 41 and detaching from the limiting socket 24 along the direction of approaching and pressing the end of the mating part 20. This ensures that the limiting plug 31 remains securely within the limiting socket 24, guaranteeing a reliable mating fit between the mating part 20 and the mating end 41. Ultimately, this ensures that the force acting on the operating part 10 is efficiently and fully transmitted to the rearview mirror arm 40 through the mating part 20, thereby improving the connection success rate between the mounting bracket connection end 43 and the arm mounting bracket.

[0037] See Figures 2-3 , Figure 5In some embodiments, the limiting insertion hole 24 is formed on the side plate 22 and extends through the side of the side plate 22 away from the docking groove 23 and the other side close to the docking groove 23. The anti-detachment wall 25 is formed on the side plate 22, thereby connecting the limiting insertion hole 24 to the docking groove 23. When the docking end 41 with the bottom slot 411 extends into the docking groove 23 and is fixedly adapted to the inner wall of the docking groove 23, the limiting insertion hole 24 and the bottom slot 411 are coaxially arranged and connected. Therefore, the limiting pin can be directly inserted into the bottom slot 411 after passing through the side plate 22 along the axial direction of the limiting insertion hole 24.

[0038] Optionally, the axial direction of the limiting hole 24 is consistent with the thickness direction of the side plate 22 and perpendicular to the bottom plate 21. The limiting pin, when passing through the limiting hole 24, is spaced apart from the bottom plate 21. The anti-detachment wall 25 extends to the side of the limiting pin away from the bottom plate 21. (See reference...) Figure 2 and Figure 4 Preferably, the wall of the limiting hole 24 is closed circumferentially along the limiting pin. With this configuration, the limiting pin can only pass through the limiting hole 24 axially, meaning it can only penetrate the side plate 22 along its thickness and extend into the bottom slot 411. Furthermore, the outer periphery of the limiting pin forms an interference fit with the inner wall of the limiting hole 24. This configuration effectively reduces the possibility of the limiting pin disengaging from the limiting hole 24, and consequently, from the mating end 41.

[0039] In some embodiments, the wall of the limiting insertion hole 24 includes a first anti-rotation wall 251 and a second anti-rotation wall 252 forming an included angle, and the outer peripheral wall of the limiting plug 31 includes a first mating wall 311 and a second mating wall forming an included angle, wherein the first mating wall 311 and the second mating wall are respectively adapted to the first anti-rotation wall 251 and the second anti-rotation wall 252. See also Figures 2-3 The first anti-rotation wall 251 and the second anti-rotation wall 252 are both planar and inclined towards the base plate 21 and the operating part 10, thus forming the aforementioned anti-detachment wall 25. The first mating wall 311 and the second mating wall are both located on the outer periphery of the limiting pin, both are planar and inclined away from the base plate 21. When the limiting pin passes through the limiting insertion hole 24, the included angle between the first anti-rotation wall 251 and the second anti-rotation wall 252 is numerically equal to the included angle between the first mating wall 311 and the second mating wall, and the first anti-rotation wall 251 and the second anti-rotation wall 252 are respectively fixedly attached to the first mating wall 311 and the second mating wall.

[0040] like Figures 2-3As shown, an anti-rotation angle is formed between the first anti-rotation wall 251 and the second anti-rotation wall 252. This anti-rotation angle has an opening facing away from the end of the mating part 20 and towards the base plate 21 and the operating part 10. The first mating wall 311 and the second mating wall form an anti-rotation protrusion. The anti-rotation protrusion extends along the length direction of the limiting plug 31. The length direction of the limiting plug 31 is the same as the length direction of the limiting pin. This length direction is the same as the thickness direction of the side plate 22 and the axial direction of the limiting hole 24. If the limiting pin is cut with a plane parallel to the side plate 22, the angle between the first mating wall 311 and the second mating wall is equal in size to the anti-rotation angle.

[0041] With this configuration, when the limiting pin passes through the limiting hole 24, the first anti-rotation wall 251 and the second anti-rotation wall 252 respectively abut against the first mating wall 311 and the second mating wall, the limiting pin is not easy to rotate within the limiting hole 24.

[0042] like Figures 2-3 As shown, optionally, the opening shape of the limiting socket 24 and the opening shape of the bottom slot 411 are both triangular. The limiting pin is cut with a plane parallel to the side plate 22, and the cross-sectional shape of the limiting pin is also triangular. This cross-sectional shape is the same as the opening shape of the limiting socket 24 and the opening shape of the bottom slot 411. With this configuration, after the limiting pin passes through the limiting socket 24 and the bottom slot 411, the mating part 20, the mating end 41, and the limiting pin are fully fixed and fit together, forming approximately a rigid whole. The force applied by the operator to the operating part 10 can thus be efficiently transmitted to the card seat connection end 43 through the rigid whole formed by the mating part 20, the mating end 41, and the limiting pin, ensuring that the mating end 41 will not rotate relative to the mating part 20 around a straight line parallel to the axis of the limiting socket 24 during the application of force to the operating part 10.

[0043] Preferably, the opening shapes of the limiting socket 24 and the bottom slot 411 are both equilateral triangles. The limiting pin is cut with a plane parallel to the side plate 22, and the cross-sectional shape of the limiting pin is also an equilateral triangle. This cross-sectional shape is the same as the opening shape of the limiting socket 24 and the opening shape of the bottom slot 411. With this configuration, the limiting pin can be inserted into the limiting socket 24 and the bottom slot 411 in three different postures, which greatly improves the convenience for the operator to insert the limiting pin through the side plate 22 and into the mating end 41, without limiting the limiting pin to be inserted into the limiting socket 24 and the bottom slot 411 in a specific posture.

[0044] It is understood that in other embodiments, the opening shape of the limiting insertion hole 24 and the opening shape of the bottom slot 411 are not limited to triangles, and the cross-sectional shape formed by the limiting pin being cut by a plane parallel to the side plate 22 is not limited to triangles, but can also be other shapes, such as polygons with more than three sides. As long as the first anti-rotation wall 251 and the second anti-rotation wall 252 are respectively fixedly adapted to the first mating wall 311 and the second mating wall, the rotation of the mating end 41 relative to the mating portion 20 around a straight line parallel to the axis of the limiting insertion hole 24 can be eliminated.

[0045] The circumferential closure of the wall of the limiting socket 24 along the limiting plug 31 improves the durability and rigidity of the mating part 20. In other embodiments, the wall of the limiting socket 24 may not need to be closed circumferentially along the limiting plug 31. For example, if the mechanical properties of the mating part 20 meet the requirements, the wall of the limiting socket 24 may also be open, as long as the anti-detachment wall 25 extends to the side of the limiting plug 31 near the end of the mating part 20 and can stop the mating end 41 from detaching from the mating part 20 on the side of the limiting plug 31 near the end of the mating part 20.

[0046] In order to meet the durability and mechanical performance requirements of the limiting plug 31, in some embodiments, the limiting plug 31 is a metal part.

[0047] See Figures 2-3 The rearview mirror installation tool shown has three side plates 22 and a rectangular plate structure for the base plate 21. The three side plates 22 are bent and connected to the three different outer edges of the base plate 21. The base plate 21 and the three side plates 22 together form a docking groove 23. One side plate 22 has a disassembly side hole 26 and the other side plate 22 has a limit insertion hole 24. The docking part 20 is also constructed with an anti-interference clearance gap. The anti-interference clearance gap is formed between the two side plates 22 and is set opposite to the side plate 22 with the disassembly side hole 26. When the docking end 41 extends into and out of the docking groove 23, the ball head 42 can pass through the anti-interference clearance gap.

[0048] Optionally, see Figure 3 The limiting part 30 also includes limiting retaining ribs 33. Each of the two side plates 22 forming the anti-interference clearance gap is provided with limiting retaining ribs 33. The two limiting retaining ribs 33 and the side plate 22 with the disassembly side hole 26 are arranged facing each other. The limiting retaining ribs 33 can further improve the wrapping and fixing effect of the multiple side plates 22 on the docking end 41, and improve the connection stability between the docking part 20 and the docking end 41. When the docking end 41 is inserted into the docking groove 23, the limiting retaining ribs 33 can abut against the side wall of the docking end 41 facing away from the disassembly side hole 26, and restrict the degree of freedom of the docking end 41 to rotate relative to the docking part 20 around a straight line perpendicular to the bottom plate 21.

[0049] The technical features of the above-described embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Any appropriate changes and variations made to the above embodiments within the scope of the essential spirit of the present utility model shall fall within the scope of protection claimed by the present utility model.
