Summary of the invention

[0010] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a tolerance compensation component for installing a through-type taillight of an automobile, so as to solve the difficulties of the prior art.

[0011] In order to achieve the above-mentioned purpose and other related purposes, the utility model provides a tolerance compensation member for installing a through-type taillight of an automobile, comprising:

[0012] A first connecting member 1, wherein the first connecting member 1 is slidably disposed in a groove of a matching vehicle lamp mounting member 8;

[0013] A second connecting member 2, wherein the second connecting member 2 is integrally extended and arranged at the bottom of the first connecting member 1, and the outer diameter of the second connecting member 2 is smaller than the outer diameter of the first connecting member 1, but is matched and clamped on the bayonet of the vehicle lamp mounting member 8;

[0014] A third connecting member 3, the third connecting member 3 is integrally extended and arranged on an end of the second connecting member 2 away from the first connecting member 1, and the outer diameter of the third connecting member 3 is larger than the outer diameter of the bayonet;

[0015] The first connecting member 1, the second connecting member 2 and the third connecting member 3 are provided with a through hole 4 at the same vertical central axis;

[0016] The sealing ring 5 is embedded in the end surface of the third connecting member 3 away from the second connecting member 2. When installed, the end surface of the sealing ring 5 away from the third connecting member 3 is against the body sheet metal 9 matched with the lamp mounting member 8.

[0017] Furthermore, the first connecting member 1 , the second connecting member 2 and the third connecting member 3 are coaxially arranged.

[0018] In the present technical solution, a first connecting member 1, a second connecting member 2 and a third connecting member 3 with different outer diameters are used to form a groove structure on the body of the tolerance compensating member. The groove structure is adapted to the slide groove structure of the headlight mounting member 8, and the tolerance compensating member can be conveniently inserted into the slide groove by sliding during installation. In addition, a through hole 4 is provided at the center of the structure. After the tolerance compensating member, the headlight mounting member 8 and the body sheet metal 9 are installed, the connecting bolt passes through the through hole 4, the headlight mounting member 8 and the body sheet metal 9 to achieve a fastening effect between the three, without being limited by the matching nuts and limited structures of the product, thereby achieving a small volume effect, making it easier to integrate the tolerance compensating member into the product with the through-type taillight slide groove for installing the tolerance compensation.

[0019] According to a preferred solution, the outer diameter of the third connecting member 3 is not less than the outer diameter of the first connecting member 1 .

[0020] Furthermore, the first connecting member 1 and the third connecting member 3 are arranged in parallel.

[0021] In the present technical solution, the first connecting member 1 is used to be inserted into the headlight mounting member 8 during installation. Since the installation position in the headlight mounting member 8 is fixed, the maximum size of the first connecting member 1 is limited in the present embodiment. At the same time, it is also preferred that the outer diameter of the first connecting member 1 is slightly smaller than the inner size of the inner slide groove of the headlight mounting member 8, so as to achieve the effect of conveniently introducing the tolerance compensation member. The third connecting member 3 is located between the headlight mounting member 8 and the body sheet metal 9 during installation. There is no direct size limitation on the installation size of the third connecting member 3. Therefore, the outer diameter of the third connecting member 3 can be set to be not less than the outer diameter of the first connecting member 1, so that there is a sufficient contact area between the third connecting member 3 and the body sheet metal 9, which reduces the concentration of local stress, enhances the connection strength of the overall structural compensation area, improves the service life of the tolerance compensation member, and effectively increases the sealing performance between the tolerance compensation member and the body sheet metal 9.

[0022] In addition, it is preferred to set the first connecting member 1 and the third connecting member 3 in parallel, which can reduce the dimensional error caused by angle deviation, thereby improving the overall accuracy of the product, and can also reduce the deformation caused by uneven stress distribution, thereby improving the stability of the product, while reducing the difficulty of assembly and improving installation efficiency.

[0023] According to a preferred embodiment, the first connecting member 1 has a quadrilateral structure in the direction of orthographic projection.

[0024] Furthermore, the first connecting member 1 has a square structure in the direction of orthographic projection.

[0025] In the present technical solution, the groove of the matching headlight mounting part 8 also adopts a square structure, and the square structure is also a conventional structure. After the first connecting part 1, which is a quadrilateral and preferably a square, is installed into the corresponding groove, a limit can be formed, and when the bolt is in the locking process, the bolt will be rotated and locked. Once the tolerance compensation part is not a square structure but a circular structure, the tolerance compensation part and the bolt will rotate together, resulting in the bolt being unable to be locked. It is not suitable for the needs of quick installation.

[0026] According to a preferred embodiment, rounded corners 6 are formed on both sides of one end of the first connecting member 1 close to the vehicle lamp mounting member 8 .

[0027] Furthermore, the first connecting member 1 is provided with rounded corners 6 on all four sides.

[0028] In the present technical solution, the first connecting member 1 is provided with chamfered corners in the circumferential direction, and the chamfered corners can make the edge of the connecting member smooth. On the one hand, the chamfered corners can play a guiding role, which is conducive to smoothly introducing the first connecting member 1 into the insertion groove for matching the insertion groove of the headlight mounting member 8, thereby improving the assembly efficiency and reducing the difficulty of aligning parts; on the other hand, the risk of scratching the inner side of the introduction groove around the first connecting member 1 is reduced.

[0029] According to a preferred solution, the third connecting member 3 is arranged in a circular shape in the direction of the orthographic projection.

[0030] Furthermore, the outer diameter of the third connecting member 3 is greater than the width of the first connecting member 1 .

[0031] In the present technical solution, the first connecting member 1 is a square structure, and the third connecting member 3 is a circular structure. Since the present embodiment is connected by bolts passing through the headlight mounting member 8 and the body sheet metal 9 after installation, the opening of the body sheet metal 9 corresponding to the bolt installation is also circular. Since the connection areas of the bolts and nuts are also circular, this is conducive to making the third connecting member 3 and the body sheet metal 9 easier to fit together, and the fitting effect can also better achieve a sealing effect, and further, the sealing ring 5 forms a uniform pressure around it, so that the connection structure of the tolerance compensation part is more stable.

[0032] According to a preferred solution, an annular groove 7 is provided at the installation position of the third connecting member 3 corresponding to the sealing ring 5 .

[0033] Furthermore, in the initial state, the sealing ring 5 is adhered in the annular groove 7 by adhesive.

[0034] In the present technical solution, the first connecting member 1, the second connecting member 2 and the third connecting member 3 act as tolerance compensators, and the sealing ring 5 plays a sealing effect between the tolerance compensators and the corresponding body sheet metal 9. Therefore, after the tolerance compensators are installed, it is still necessary to ensure that the surface of the third connecting member 3 is in close contact with the surface of the body sheet metal 9, and an annular groove 7 is provided on the third connecting member 3. The annular groove 7 can provide an installation position for the sealing ring 5 to avoid a gap between the third connecting member 3 and the body sheet metal 9. At the same time, the sealing ring can be easily installed, thereby improving the accuracy and efficiency of the installation.

[0035] In addition, the sealing ring 5 is glued in the annular groove 7 by adhesive before leaving the factory, so that during the loading and transportation process, the tolerance compensation part still maintains an integrated structure, preventing the sealing ring from shifting or falling off during transportation or even installation.

[0036] According to a preferred solution, the horizontal width of the cross section of the sealing ring 5 is smaller than the corresponding width of the annular groove 7 .

[0037] Furthermore, the sealing ring 5 is coaxially arranged in the annular groove 7 , and the distances between the two sides of the sealing ring 5 and the side walls of the annular groove 7 are the same.

[0038] In the present technical solution, the width of the sealing ring 5 is designed to be smaller than the width of the annular groove 7, so that space can be reserved in the annular groove 7. This space is used as an area for the sealing ring 5 to deform. After installation, the fit between the tolerance compensation part and the surface of the vehicle body sheet metal 9 can still be guaranteed. While achieving the sealing effect, the generation of gaps can be avoided without affecting the difficulty of installation.

[0039] According to a preferred solution, before installation, the height of the sealing ring 5 is greater than the depth of the annular groove 7 .

[0040] Furthermore, before installation, the sealing ring 5 protrudes out of the annular groove 7 .

[0041] In the present technical solution, the height of the sealing ring 5 is set to be higher than the depth of the annular groove 7, which can provide the sealing ring 5 with a compressive deformation amount. Since the horizontal width of the cross section of the sealing ring 5 is smaller than the corresponding width of the annular groove 7, during the process of tightening and squeezing between the tolerance compensation part and the body sheet metal 9 by bolts, the sealing ring 5 in the high annular groove 7 can be compressed and deformed toward the reserved space around it under the action of extrusion. While filling the reserved space, it can also achieve a sealing effect, while taking into account the service life of the sealing ring 5.

[0042] According to a preferred solution, the sealing ring 5 is made of soft rubber material.

[0043] In the present technical solution, since the rubber ring used for the sealing ring 5 is made of soft rubber material, in the actual use of the tolerance compensation part, the sealing ring 5 will be compressed and deformed to a certain deformation amount, that is, when the sealing ring 5 is squeezed and flush with the surface of the third connecting member 3 around the annular groove 7, these compressed rubbers will fill the entire annular groove 7, achieving the effect of being tightly connected with the surface of the vehicle body sheet metal 9, thereby achieving good sealing.

[0044] According to a preferred embodiment, the first connecting member 1, the second connecting member 2 and the third connecting member 3 are integrally provided and made of PPA-GF50 material.

[0045] In the present technical solution, the first connector 1, the second connector 2 and the third connector 3 in the tolerance compensation part are all made of PPA-GF50 material to replace the conventionally used metal material, which can solve the problem of salt spray and release the stress generated by the through-type taillights in different environments and at different temperatures, thereby avoiding stress concentration and then causing fracture.

[0046] The utility model has the following beneficial effects:

[0047] (1) A first connecting member 1, a second connecting member 2 and a third connecting member 3 are used to form a matching structure with an annular groove in the middle to fit into the lamp mounting member 8, thereby effectively reducing the volume of the tolerance adjustment member. A through hole 4 is provided at the center axis position to realize bolt installation, so that the small-volume tolerance adjustment member is easier to integrate on the lamp mounting member 8 and the body sheet metal 9;

[0048] (2) After installation, the through-type taillights can effectively release stress at different temperatures;

[0049] (3) The first connecting member 1 is in a square structure, and is matched with a square mounting groove of the lamp mounting member 8, so that the tolerance compensation member can be prevented from rotating when the bolt is installed;

[0050] (4) The annular structure of the third connecting member 3 is matched with the circular structure of the bolt and the opening of the body sheet metal 9, and the sealing ring 5 used in combination has a sealing effect between the body sheet metal 9 and the body sheet metal 9.

[0072] The utility model proposes a tolerance compensating part for installing a through-type taillight of an automobile, which is used in the tolerance compensating process for installing the taillight. The utility model does not limit the type of the taillight, but the structure of the tolerance compensating part for installing the through-type taillight of an automobile is particularly suitable for the installation requirements of the through-type taillight.

[0073] In general, the tolerance compensation member for installing a through-type taillight of an automobile proposed in the present invention mainly comprises a first connecting member 1, a second connecting member 2, a third connecting member 3, and a sealing ring 5. Figure 1 , which shows the arrangement relationship among the first connecting member 1 , the second connecting member 2 , the third connecting member 3 , and the sealing ring 5 .

[0074] In order to achieve the purpose of reducing the volume of parts but compensating for the installation tolerance under limited installation space, the problem that the existing compensating adjustment parts in the background technology do not have a sealing function, and the inflow of impurities and rainwater cannot be avoided after installation, and long-term exposure to a humid environment will cause the metal parts inside the taillight to rust, and the plastic parts to crack or deform, thereby shortening the service life of the taillight; on the other hand, nuts are required for use in conjunction, and the structural design is limited, the use space is also limited, and it is impossible to make small-volume parts, and the installation is cumbersome, which will increase the cost; on the other hand, the compensating adjustment parts are metal parts, there is a salt spray problem, and the stress release effect on the through-type taillight is poor, and the sealing effect is reduced accordingly; for this reason, the technical solution provided in this embodiment The first connecting member 1, the second connecting member 2 and the third connecting member 3 are used to form a matching structure with an annular groove in the middle to adapt to the lamp mounting member 8, which effectively reduces the volume of the tolerance adjustment member, and a through hole 4 is opened at the center axis position to realize bolt installation, so that the small-volume tolerance adjustment member is easier to integrate on the lamp mounting member 8 and the body sheet metal 9, and the installed through-type taillight can effectively release stress at different temperatures; in addition, the first connecting member 1 is a square structure, which is matched with the square mounting groove of the lamp mounting member 8, which can avoid the tolerance compensation member from rotating when the bolt is installed, and the annular structure of the third connecting member 3 is matched with the circular structure of the bolt and the opening of the body sheet metal 9, and the sealing ring 5 used in conjunction with the body sheet metal 9 has a sealing effect between the body sheet metal 9.

[0075] Specifically, Figure 1 As shown, from top to bottom, it includes a first connecting member 1, a second connecting member 2 and a third connecting member 3 which are integrally and coaxially formed, wherein the first connecting member 1 is slidably set in the groove of the matching headlight mounting member 8, the second connecting member 2 is integrally extended and set at the bottom of the first connecting member 1, and the outer diameter of the second connecting member 2 is smaller than the outer diameter of the first connecting member 1, and the second connecting member 2 can be used to form a reduced diameter annular groove structure under the first connecting member 1, which is convenient for matching and clamping on the bayonet of the headlight mounting member 8, and then, the third connecting member 3 is integrally extended and set on the end of the second connecting member 2 away from the first connecting member 1, and the outer diameter of the third connecting member 3 is larger than the outer diameter of the bayonet, and is used to form a tight connection with the body sheet metal 9.

[0076] When in use, the first connecting member 1, the second connecting member 2 and the third connecting member 3 are provided with a through hole 4 on the same vertical central axis. The bolts are passed through the corresponding connecting holes of the headlight mounting member 8, the tolerance compensation member and the body sheet metal 9 in turn, and the bolts are locked with nuts, so that the tolerance compensation member can be installed with bolt locking.

[0077] As mentioned above, the tolerance compensating part provided in this embodiment utilizes the first connecting part 1, the second connecting part 2 and the third connecting part 3 with different outer diameters to form a groove structure on the body of the tolerance compensating part. The groove structure is adapted to the slide groove structure of the headlight mounting part 8, and the tolerance compensating part can be conveniently inserted into the slide groove by sliding during installation. In addition, a through hole 4 is provided at the center position of the structure. After the tolerance compensating part is installed with the headlight mounting part 8 and the body sheet metal 9, the connecting bolt passes through the through hole 4, the headlight mounting part 8 and the body sheet metal 9 to achieve a fastening effect between the three, and will not be limited by the matching nuts and limited structures of the product, thereby achieving a small volume effect, and achieving the purpose of making the tolerance compensating part easier to integrate into the product with the through-type taillight slide groove installation tolerance compensation.

[0078] Considering that the installation position in the headlight mounting member 8 is fixed, and the first connecting member 1 needs to be inserted into the corresponding groove in the headlight mounting member 8 during installation, the maximum size of the first connecting member 1 is limited in this embodiment, and it is also preferred that the outer diameter of the first connecting member 1 is slightly smaller than the inner size of the inner groove of the headlight mounting member 8, so as to achieve the effect of conveniently introducing the tolerance compensation member; and for the third connecting member 3, since the third connecting member 3 is located between the headlight mounting member 8 and the body sheet metal 9 during installation, the installation size of the third connecting member 3 is not directly limited in size, so the outer diameter of the third connecting member 3 can be set to be not less than the outer diameter of the first connecting member 1, so that there is a sufficient contact area between the third connecting member 3 and the body sheet metal 9, so that the concentration of local stress is reduced, the connection strength of the overall structural compensation area is enhanced, the service life of the tolerance compensation member is improved, and the sealing performance between the tolerance compensation member and the body sheet metal 9 can be effectively increased;

[0079] On this basis, the groove of the matching headlight mounting member 8 in this embodiment adopts a square structure, and the square structure is also a conventional structure. On the one hand, the first connecting member 1 is a quadrilateral structure in the direction of the orthographic projection, and after the first connecting member 1, which is preferably a square, is installed into the corresponding groove, a kind of limit can be formed, and when the bolt is in the locking process, the bolt will be rotated and locked. Once the tolerance compensation member is not a square structure, but a circular structure, the tolerance compensation member and the bolt will rotate together, resulting in the bolt being unable to be locked, which is not suitable for the needs of quick installation;

[0080] On the other hand, the first connecting member 1 is provided with rounded corners in the circumferential direction. The rounded corners can make the edge of the connecting member smooth. On the one hand, the rounded corners can play a guiding role. For the insertion groove of the matching lamp mounting member 8, it is beneficial to smoothly guide the first connecting member 1 into the insertion groove, thereby improving the assembly efficiency and reducing the difficulty of aligning the parts. On the other hand, the risk of scratching the inner side of the introduction groove by the surrounding of the first connecting member 1 is reduced.

[0081] In addition, it is preferred to set the first connecting member 1 and the third connecting member 3 in parallel, which can reduce the dimensional error caused by angle deviation, thereby improving the overall accuracy of the product, and can also reduce the deformation caused by uneven stress distribution, thereby improving the stability of the product, while reducing the difficulty of assembly and improving installation efficiency.

[0082] On this basis, in this embodiment, the first connecting member 1 and the third connecting member 3 are preferably arranged in different types of structures, and the third connecting member 3 is arranged in a circular shape from the direction of the orthographic projection. Since the present embodiment is connected by bolts passing through the headlight mounting member 8 and the body sheet metal 9 after installation, the opening of the body sheet metal 9 corresponding to the bolt installation is also circular. Since the connection areas of the bolts and nuts are also circular, this is conducive to making the third connecting member 3 and the body sheet metal 9 easier to fit together; and in this structure, the outer diameter of the third connecting member 3 is greater than the width of the first connecting member 1, which increases the contact area between the third connecting member 3 and the body sheet metal 9, so that the fitting area is larger, the effect is better, and the sealing effect can be more achieved. Furthermore, the sealing ring 5 can form a uniform pressure around it, effectively improving the stability of the connection structure of the tolerance compensation member.

[0083] like Figure 1 As shown, the first connecting member 1, the second connecting member 2 and the third connecting member 3 act as tolerance compensating members, and the sealing ring 5 has a sealing effect between the tolerance compensating members and the corresponding body sheet metal 9; it should be specifically explained that a sealing ring 5 is embedded in the end face of the third connecting member 3 away from the second connecting member 2. During installation, the end face of the sealing ring 5 away from the third connecting member 3 is abutted against the body sheet metal 9 matching the headlight mounting member 8, thereby achieving a sealing effect, and correspondingly, an annular groove 7 is provided on the third connecting member 3 at the installation position of the sealing ring 5.

[0084] Specifically, after the tolerance compensation member is installed, in order to still ensure the close contact between the surface of the third connecting member 3 and the surface of the body sheet metal 9, an annular groove 7 is provided on the third connecting member 3. The annular groove 7 can provide an installation position for the sealing ring 5, thereby avoiding a gap between the third connecting member 3 and the body sheet metal 9. At the same time, the sealing ring can be easily installed, thereby improving the accuracy and efficiency of the installation.

[0085] In addition, the sealing ring 5 is glued in the annular groove 7 by adhesive before leaving the factory, so that during the loading and transportation process, the tolerance compensation part still maintains an integrated structure, preventing the sealing ring from shifting or falling off during transportation or even installation.

[0086] In order to achieve a good sealing effect of the sealing ring 5, in this embodiment, the tolerance compensation part before being installed with the lamp mounting part 8 and the body sheet metal 9, in terms of structure, on the one hand, the horizontal width of the cross section of the sealing ring 5 is smaller than the corresponding width of the annular groove 7. When installed at the factory, the sealing ring 5 is coaxially arranged in the annular groove 7, and the spacing between the two sides of the sealing ring 5 and the two side walls of the annular groove 7 is the same. The width of the sealing ring 5 is designed to be smaller than the width of the annular groove 7, so that space can be reserved in the annular groove 7. The space is used as an area for the sealing ring 5 to deform. After installation, the fit between the tolerance compensation part and the surface of the body sheet metal 9 can still be ensured, and the generation of gaps can be avoided while achieving a sealing effect, and the difficulty of installation will not be affected.

[0087] On the other hand, the height of the sealing ring 5 is greater than the depth of the annular groove 7, that is, the sealing ring 5 protrudes out of the annular groove 7, which can provide the sealing ring 5 with a compressive deformation amount. Since the horizontal width of the cross section of the sealing ring 5 is smaller than the corresponding width of the annular groove 7, during the process of tightening and squeezing between the tolerance compensation part and the body sheet metal 9 by bolts, the sealing ring 5 in the high annular groove 7 can be compressed and deformed toward the reserved space around it under the action of extrusion, thereby filling the reserved space and achieving a sealing effect while taking into account the service life of the sealing ring 5.

[0088] In addition, in the present embodiment, preferably, the rubber ring used for the sealing ring 5 is made of soft rubber material. In the actual use of the tolerance compensation part, the sealing ring 5 will be compressed and deformed to a certain deformation amount. That is, when the sealing ring 5 is squeezed and flush with the surface of the third connecting member 3 around the annular groove 7, the compressed rubber will fill the entire annular groove 7, thereby achieving the effect of being tightly connected with the surface of the vehicle body sheet metal 9 and achieving good sealing.

[0089] The first connecting member 1, the second connecting member 2 and the third connecting member 3 are integrally arranged and made of PPA-GF50 material instead of conventional metal materials, which can solve the problem of salt spray and release the stress generated by the through-type taillights in different environments and at different temperatures, thereby avoiding stress concentration and causing breakage.

[0090] like Figure 7 As shown, during installation, first install the tolerance compensation member in the slide groove corresponding to the headlight mounting member 8, the first connecting member 1 is inserted into the slide groove, the second connecting member 2 is located in the slot, and the third connecting member 3 is located outside the headlight mounting member 8;

[0091] Then, the entire vehicle lamp is moved to the sheet metal opening of the vehicle body sheet metal 9 to be installed, so that the through hole 4 of the tolerance compensation piece is aligned with the sheet metal opening;

[0092] Next, the bolt is passed through the headlight mounting part 8, the through hole 4 of the tolerance compensation part, and then the sheet metal opening of the body sheet metal 9, and the nut on the other side of the sheet metal is locked on the bolt to compensate for the gap between the headlight and the body sheet metal. In addition, the tightening pressure causes the rubber ring to deform and cooperate with the bolt to form a sealing structure.

[0093] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
