Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of vehicles, in particular to a plastic part and a vehicle. Background Art
[0002] In the production of the automotive industry, a metal spacer is often embedded in an injection molded part, which can strengthen the structural strength of the injection molded part at the embedding position, transfer the pressure originally borne by the injection molded part to the metal spacer, and avoid cracking of the injection molded part due to excessive stress. Currently, there are generally two methods to embed the metal spacer into the injection molded part. The first is thermoplastic assembly, where the metal spacer is placed in the injection mold and molded together with the injection molded part. The second is cold insertion assembly. After the injection molded part is formed, the metal spacer is pressed into the reserved hole of the injection molded part by external force.
[0003] Disadvantages of the second method: When the metal spacer is pressed into the reserved hole of the injection molded part, it is difficult to match the aperture of the assembly hole of the injection molded part with the outer diameter of the metal spacer. When the metal spacer is too small, the metal spacer becomes loose after assembly. When the metal spacer is too large, the metal spacer cannot be inserted into the injection molded part.
[0004] Therefore, it is a problem to be solved that the metal spacer is likely to become loose or difficult to be pressed in during cold insertion assembly. Summary of the Utility Model
[0005] The purpose of the utility model is to provide a plastic part, aiming to solve the problem that the insert is likely to become loose or difficult to be pressed in during cold insertion assembly of the plastic part.
[0006] To achieve the above purpose, the utility model adopts the following technical scheme:
[0007] The utility model provides a plastic part, including a plastic part body. The plastic part body is provided with a receiving hole, and a first protrusion is arranged on the inner wall surface of the receiving hole.
[0008] The plastic part further includes an insert, which is arranged in the receiving hole and is located on the side of the first protrusion facing away from the inner wall surface of the receiving hole.
[0009] The plastic part provided by the embodiment of the present application is provided with a receiving hole on the plastic part, and a first protrusion is arranged in the receiving hole. During the process of the insert being embedded in the receiving hole, the corners of the insert that first come into contact with the first protrusion can cut the first protrusion, so that the outer wall surface of the insert contacts the first protrusion in the receiving hole. When the insert is arranged in the receiving hole, the insert is located on the side of the first protrusion facing away from the inner wall surface of the receiving hole. The first protrusion can limit the insert to prevent the insert from sliding out of the receiving hole. During production, as long as the outer diameter of the insert and the aperture of the receiving hole of the plastic part body are controlled within a reasonable manufacturing tolerance range, a stable fit between the insert and the plastic part body can be achieved. The insert will not fall off from the receiving hole, nor is there a risk of the insert squeezing and breaking the receiving hole of the plastic part body.
[0010] In some embodiments, the number of the first protrusions is plural, and the plural first protrusions are arranged at intervals along the circumferential direction of the accommodation hole.
[0011] In this way, by arranging the plural first protrusions at intervals along the circumferential direction of the accommodation hole, the plural first protrusions can apply a force towards the central axis of the accommodation hole to the insert, so as to limit the insert and prevent the position of the insert in the accommodation hole from shifting.
[0012] In some embodiments, the plural first protrusions are strip-shaped, and the length direction of the first protrusion is consistent with the axial direction of the accommodation hole.
[0013] In this way, by setting the length direction of the plural first protrusions to be consistent with the axial direction of the accommodation hole, the contact area between the first protrusions and the insert is larger, so that the limiting ability of the first protrusions to the insert is stronger, making the insert more stable in the accommodation hole and preventing the insert from falling off the accommodation hole.
[0014] In some embodiments, a second protrusion is further provided on the inner wall surface of the accommodation hole; the second protrusion is strip-shaped, the length direction of the second protrusion is consistent with the circumferential direction of the accommodation hole, the second protrusion intersects with the first protrusion, and the insert is further located on the side of the second protrusion facing away from the inner wall surface of the accommodation hole.
[0015] In this way, a second protrusion is further provided on the inner wall surface of the accommodation hole. Both the second protrusion and the first protrusion can limit the insert. Moreover, the second protrusion is strip-shaped, the length direction of the second protrusion is consistent with the circumferential direction of the accommodation hole, the second protrusion intersects with the first protrusion, and the first protrusion and the second protrusion can limit the insert in different orientations, making the insert more stable in the accommodation hole.
[0016] In some embodiments, the second protrusion is arranged along the entire circumference of the inner wall surface of the accommodation hole.
[0017] In this way, by arranging the second protrusions at intervals along the circumferential direction of the accommodation hole, the plural second protrusions can apply a force towards the central axis of the accommodation hole to the insert, so as to limit the insert and prevent the position of the insert in the accommodation hole from shifting.
[0018] In some embodiments, along the axial direction of the accommodation hole, the end faces at both ends of the insert are a first end face and a second end face respectively. The insert further includes an outer peripheral surface located between the first end face and the second end face, and the outer peripheral surface is connected to the first end face and the outer peripheral surface is connected to the second end face.
[0019] In this way, by connecting the outer peripheral surface to the first end face, an included angle can be formed between the outer peripheral surface and the first end face. During the process of inserting the insert into the accommodation hole, the edge formed between the outer peripheral surface and the first end face can more easily cut the first protrusion and the second protrusion, so that the stress of the first protrusion and the second protrusion on the insert reaches the best balance state.
[0020] In some embodiments, the insert is provided with a through hole, and the axial direction of the through hole is consistent with the axial direction of the receiving hole.
[0021] In this way, the through hole on the insert can be used to sleeved on the tooling for processing the plastic part. The axial direction of the through hole is consistent with the axial direction of the receiving hole, which can enable the tooling for processing the plastic part to position the insert, and then the tooling for processing the plastic part applies pressure to the insert to embed the insert into the plastic part body, so as to facilitate the processing of the plastic part by the processing tooling.
[0022] In some embodiments, a first guiding surface is provided between the inner wall surface of the through hole and the first end surface, and a second guiding surface is provided between the inner wall surface of the through hole and the second end surface; along the direction from the first end surface towards the inner wall surface of the through hole, the area surrounded by the first guiding inclined surface gradually decreases, and along the direction from the second end surface towards the inner wall surface of the through hole, the area surrounded by the first guiding inclined surface gradually decreases.
[0023] In this way, a first guiding surface is provided between the first end surface and the inner wall surface of the through hole. When there is a deviation between the through hole and the tooling for processing the plastic part, the first guiding surface can guide the processing tooling to extend into the through hole to position the insert, avoiding that when there is a deviation between the through hole and the tooling for processing the plastic part, the processing tooling cannot extend into the through hole, resulting in the processing tooling being unable to embed the insert into the plastic part body.
[0024] In some embodiments, the insert is provided with an elastic notch, and the elastic notch is located on one side of the through hole.
[0025] In this way, the elastic notch of the insert can elastically contract according to the aperture of the receiving hole of the plastic part, so that the stress of the wall surface of the receiving hole on the insert reaches the best balance state, avoiding the insert falling off from the receiving hole.
[0026] The present utility model provides another plastic part, including: a plastic part body and an insert. The plastic part body is provided with a receiving hole, and a protrusion is provided on the inner wall surface of the receiving hole; the insert is arranged in the receiving hole, and the insert is located on the side of the protrusion facing away from the inner wall surface of the receiving hole. The insert is provided with a through hole, the axial direction of the through hole is consistent with the axial direction of the receiving hole, and the insert is further provided with an elastic notch, and the elastic notch is located on one side of the through hole.
[0027] In this way, the elastic notch of the insert can elastically contract according to the aperture of the receiving hole of the plastic part, so that the stress of the wall surface of the receiving hole on the insert reaches the best balance state, avoiding the insert falling off from the receiving hole.
[0028] The present utility model provides a vehicle, including any one of the above plastic parts.
[0029] It can be understood that since the vehicle provided by the embodiments of the present application includes the plastic part as described above, the two can solve the same problems and achieve the same effects, and the present application will not elaborate herein one by one.

[0042] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

Without special instructions, under the condition of satisfying the relative positional relationship shown in the drawings, the above-mentioned orientation description can be flexibly set during the actual application process.
[0044] The terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, unless otherwise stated, the meaning of "a plurality" is two or more.
[0045] In the description of the present utility model, it should be noted that unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "communicated" should be understood in a broad sense.

[0048] In the description of this specification, specific features, structures, materials or characteristics may be combined in a suitable manner in any one or more embodiments or examples.
[0049] In industrial production, a metal spacer is often embedded in an injection molded part, which can strengthen the structural strength of the injection molded part at the embedding position, transfer the pressure originally borne by the injection molded part to the metal spacer, and prevent the injection molded part from cracking due to excessive stress. Currently, the method to embed the metal spacer into the injection molded part is cold plug assembly. After the injection molded part is formed, the metal spacer is pressed into the reserved hole of the injection molded part by external force.
[0050] The disadvantages of this method are as follows: when the metal spacer is pressed into the reserved hole of the injection molded part, it is difficult to match the aperture of the assembly hole of the injection molded part with the outer diameter of the metal spacer. When the metal spacer is too small, the metal spacer will become loose after assembly. When the metal spacer is too large, the metal spacer cannot be inserted into the injection molded part.
[0051] To achieve the above object, the present utility model adopts the following technical solutions:
[0052] As Figure 1 and Figure 2 shown, a plastic part 100 provided in this embodiment includes a plastic part body 10. The plastic part body 10 is provided with a receiving hole 11, and a first protrusion 12 is provided on the inner wall surface of the receiving hole 11.
[0053] It should be noted that the receiving hole 11 can be a through hole or a blind hole, and the present application does not limit this.
[0054] Among them, the number of the first protrusions 12 can be one or more, and the present application does not limit this.
[0055] The plastic part 100 further includes an insert 20. The insert 20 is arranged in the receiving hole 11, and the insert 20 is located on the side of the first protrusion 12 facing away from the inner wall surface of the receiving hole 11.
[0056] Among them, the material of the plastic part 100 can be, but is not limited to, plastic or rubber, and the material of the insert 20 can be, but is not limited to, metal, alloy or ceramic, etc.
[0057] It can be understood that in the vehicle body, there are a large number of components that need to be connected to each other by bolts. Some of these components are made of plastic or rubber. Therefore, the connection of the bolts cannot withstand a large force. The plastic part 100 can be used here, and the overall strength of the plastic part 100 can be improved by setting the insert 20 inside the plastic part 100.
[0058] The plastic part 100 provided by the embodiment of the present application is provided with a receiving hole 11 on the plastic part 100, and a first protrusion 12 is provided in the receiving hole 11. During the process of inserting the insert 20 into the receiving hole 11, the corners of the insert 20 that first come into contact with the first protrusion 12 can cut the first protrusion 12, so that the outer wall surface of the insert 20 contacts the first protrusion 12 in the receiving hole 11. When the insert 20 is arranged in the receiving hole 11, the insert 20 is located on the side of the first protrusion 12 facing away from the inner wall surface of the receiving hole 11. The first protrusion 12 can limit the insert 20 to prevent the insert 20 from sliding out of the receiving hole 11. During production, as long as the outer diameter of the insert 20 and the diameter of the receiving hole 11 of the plastic part body 10 are controlled within a reasonable manufacturing tolerance range, a stable fit between the insert 20 and the plastic part body 10 can be achieved. The insert 20 will not fall off from the receiving hole 11, nor is there a risk that the insert 20 will squeeze and break the receiving hole 11 of the plastic part body 10.
[0059] In some embodiments, such as Figure 2 and Figure 3 shown, the number of the first protrusions 12 is multiple, and the multiple first protrusions 12 are arranged at intervals along the circumferential direction of the receiving hole 11.
[0060] In this way, by arranging the multiple first protrusions 12 at intervals along the circumferential direction of the receiving hole 11, the multiple first protrusions 12 can apply a force towards the central axis of the receiving hole 11 to the insert 20 to limit the insert 20 and prevent the position of the insert 20 in the receiving hole 11 from shifting.
[0061] In some embodiments, the number of the first protrusions 12 is three, and the three first protrusions 12 are arranged evenly at intervals along the circumferential direction of the receiving hole 11.
[0062] In this way, by arranging the three first protrusions 12 evenly at intervals along the circumferential direction of the receiving hole 11, the three first protrusions 12 are arranged in a triangular shape in the receiving hole 11, and the three first protrusions 12 jointly limit the insert 20, which can prevent the insert 20 from shifting in the receiving hole 11 due to uneven force.
[0063] In some embodiments, the number of the first protrusions 12 is four, and the four first protrusions 12 are arranged evenly at intervals along the circumferential direction of the receiving hole 11.
[0064] In this way, the four first protrusions 12 are evenly spaced along the circumferential direction of the accommodation hole 11, and the four first protrusions 12 are symmetrically arranged in the accommodation hole 11, which can prevent the insert 20 from shifting in position due to uneven force in the accommodation hole 11.
[0065] Among them, the multiple first protrusions 12 can be symmetrically arranged or asymmetrically arranged, and the present application does not limit this.
[0066] In some embodiments, such as Figure 2 and Figure 3 shown, the multiple first protrusions 12 are strip-shaped, and the length direction of the first protrusion 12 is consistent with the axial direction of the accommodation hole 11.
[0067] In this way, the contact area between the first protrusion 12 and the insert 20 can be made larger, so that the limiting ability of the first protrusion 12 to the insert 20 is stronger, making the insert 20 more stable in the accommodation hole 11 and preventing the insert 20 from falling out of the accommodation hole 11.
[0068] In some embodiments, along the moving direction of the insert 20 inserted into the accommodation hole 11, the thickness of the first protrusion 12 gradually increases, and the thickness of the first protrusion 12 is the length of the first protrusion 12 from the side facing away from the inner wall surface of the accommodation hole 11 to the inner wall surface of the accommodation hole 11.
[0069] In this way, when there is a deviation between the accommodation hole 11 and the insert 20, the insert 20 can be guided to be inserted into the accommodation hole 11, so that the insert 20 is located at the axis of the accommodation hole 11, so that the first protrusion 12 positions the insert 20, and it is avoided that when there is a deviation between the accommodation hole 11 and the insert 20, the insert 20 cannot be inserted into the accommodation hole 11 or the position of the insert 20 in the accommodation hole 11 shifts.
[0070] In some embodiments, such as Figure 4 and Figure 5 shown, a second protrusion 13 is further provided on the inner wall surface of the accommodation hole 11; the second protrusion 13 is strip-shaped, the length direction of the second protrusion 13 is consistent with the circumferential direction of the accommodation hole 11, the second protrusion 13 intersects with the first protrusion 12, and the insert 20 is also located on the side of the second protrusion 13 facing away from the inner wall surface of the accommodation hole 11.
[0071] In this way, a second protrusion 13 is further provided on the inner wall surface of the accommodation hole 11. Both the second protrusion 13 and the first protrusion 12 can limit the insert 20, and the second protrusion 13 is strip-shaped, the length direction of the second protrusion 13 is consistent with the circumferential direction of the accommodation hole 11, the second protrusion 13 intersects with the first protrusion 12, and the first protrusion 12 and the second protrusion 13 can limit the insert 20 in different orientations, making the insert 20 more stable in the accommodation hole 11.
[0072] In some embodiments, the material of the second protrusion 13 can be a colloid.
[0073] In this way, the second protrusion 13 can bond the plastic part body 10 and the insert 20, making the connection between the plastic part body 10 and the insert 20 more firm and preventing the insert 20 from shifting within the plastic part body 10.
[0074] In some embodiments, such as Figure 4 , Figure 5 and Figure 6 shown, the second protrusion 13 is arranged along the inner wall surface of the accommodation hole 11 for one week.
[0075] In this way, by arranging the second protrusions 13 at intervals along the circumferential direction of the accommodation hole 11, a plurality of second protrusions 13 can apply a force towards the central axis of the accommodation hole 11 to the insert 20 to limit the insert 20 and prevent the position of the insert 20 within the accommodation hole 11 from shifting. And by arranging the second protrusions 13 along the inner wall surface of the accommodation hole 11 for one week, the side of the second protrusion 13 away from the inner wall surface of the accommodation hole 11 contacts the insert 20, making the second protrusion 13 surround the outer wall surface of the insert 20 for one week, and the second protrusion 13 can also play a sealing role for blocking water or oil, etc.
[0076] In some embodiments, such as Figure 7 , Figure 8 and Figure 9 shown, along the axial direction of the accommodation hole 11, the end faces at both ends of the insert 20 are the first end face 21 and the second end face 22 respectively. The insert 20 further includes an outer peripheral surface 23 located between the first end face 21 and the second end face 22. The outer peripheral surface 23 is connected to the first end face 21, and the outer peripheral surface 23 is connected to the second end face 22.
[0077] In this way, by connecting the outer peripheral surface 23 to the first end face 21, an angle can be formed between the outer peripheral surface 23 and the first end face 21. During the process of inserting the insert 20 into the accommodation hole 11, the edge formed between the outer peripheral surface 23 and the first end face 21 can cut the first protrusion 12 and the second protrusion 13, so that the stress of the first protrusion 12 and the second protrusion 13 on the insert 20 reaches the best balance state.
[0078] In some embodiments, such as Figure 7 and Figure 9 shown, the angles between the outer peripheral surface 23 and the first end face 21 and between the outer peripheral surface 23 and the second end face 22 are both right angles.
[0079] In this way, the edge formed between the outer peripheral surface 23 and the first end face 21 can more easily cut the first protrusion 12 and the second protrusion 13. Compared with setting the angles between the outer peripheral surface 23 and the first end face 21 and between the outer peripheral surface 23 and the second end face 22 as obtuse angles or acute angles, the insert 20 can be placed stably, thus facilitating the storage and processing of the insert 20.
[0080] It should be noted that the included angle between the outer peripheral surface 23 and the first end surface 21 can be an obtuse angle, a right angle or an acute angle, and the included angle between the outer peripheral surface 23 and the second end surface 22 can also be an obtuse angle, a right angle or an acute angle. The included angle between the outer peripheral surface 23 and the first end surface 21 and the included angle between the outer peripheral surface 23 and the second end surface 22 can be the same or different, and the present application does not limit this.
[0081] In some embodiments, the insert 20 is provided with a through hole 24, and the axial direction of the through hole 24 is consistent with the axial direction of the accommodation hole 11.
[0082] In this way, the through hole 24 on the insert 20 can be used to sleeved on the tooling 200 for processing the plastic part 100. The axial direction of the through hole 24 is consistent with the axial direction of the accommodation hole 11, which can enable the tooling 200 for processing the plastic part 100 to position the insert 20. Then, the tooling 200 for processing the plastic part 100 applies pressure to the insert 20, so that the insert 20 is embedded into the plastic part body 10, thereby facilitating the processing of the plastic part 100 by the processing tooling 200.
[0083] In some embodiments, such as Figure 7 and Figure 8 as shown, a first guiding surface 25 is provided between the inner wall surface of the through hole 24 and the first end surface 21, and a second guiding surface 26 is provided between the inner wall surface of the through hole 24 and the second end surface 22; along the direction from the first end surface 21 towards the inner wall surface of the through hole 24, the area surrounded by the first guiding surface 25 gradually decreases, and along the direction from the second end surface 22 towards the inner wall surface of the through hole 24, the area surrounded by the second guiding surface 26 gradually decreases.
[0084] In this way, by providing the first guiding surface 25 between the first end surface 21 and the inner wall surface of the through hole 24, when there is a deviation between the through hole 24 and the tooling 200 for processing the plastic part 100, the first guiding surface 25 can guide the processing tooling 200 to extend into the through hole 24, so that the processing tooling 200 positions the insert 20, avoiding the situation that when there is a deviation between the through hole 24 and the tooling 200 for processing the plastic part 100, the processing tooling 200 cannot extend into the through hole 24, resulting in the processing tooling 200 being unable to embed the insert 20 into the plastic part body 10. The second guiding surface 26 has the same function as the first guiding surface 25, and the present application will not elaborate here.
[0085] In some embodiments, such as Figure 10 as shown, the insert 20 is provided with an elastic notch 27, and the elastic notch 27 is located on one side of the through hole 24.
[0086] It should be noted that the elastic notch 27 can be set according to the material and thickness of the insert 20, and the present application does not limit this.
[0087] In this way, the elastic notch 27 of the insert 20 can elastically contract according to the aperture of the accommodation hole 11 of the plastic part 100, so that the stress of the wall surface of the accommodation hole 11 on the insert 20 reaches the optimal balance state, and the insert 20 is prevented from falling off from the accommodation hole 11.
[0088] In some embodiments, the elastic notch 27 is strip-shaped, and the length direction of the elastic notch 27 is consistent with the axial direction of the through hole 24.
[0089] In this way, when the insert 20 is squeezed, the insert 20 can contract in its circumferential direction, and the shrinkage beams at different positions of the insert 20 are consistent, so that the insert 20 is embedded in the accommodation hole 11, and the limiting force received by the insert 20 in the accommodation hole 11 is evenly distributed, avoiding dislocation of the insert 20 due to uneven force on the insert 20.
[0090] The present utility model provides another plastic part 100, including: a plastic part body 10 and an insert 20. The plastic part body 10 is provided with an accommodation hole 11, and a protrusion is arranged on the inner wall surface of the accommodation hole 11; the insert 20 is arranged in the accommodation hole 11, and the insert 20 is located on the side of the protrusion facing away from the inner wall surface of the accommodation hole 11. The insert 20 is provided with a through hole 24, the axial direction of the through hole 24 is consistent with the axial direction of the accommodation hole 11, and the insert 20 is further provided with an elastic notch 27, and the elastic notch 27 is located on one side of the through hole 24.
