DETAILED DESCRIPTION

[0028] In order to make the purpose, technical scheme and advantages of the utility model clearer, the technical scheme in the utility model embodiment will be clearly and completely described in combination with the drawings in the utility model embodiment below. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0029] Embodiment one

[0030] Referring to Figures 1-8 The utility model discloses an engine cover support mechanism, including support rod 1 and support head 2, be provided with first joint part 3 and first limit portion 4 on support rod 1, be provided with second joint part 5 and second limit portion 6 on support head 2, first joint part 3 and second joint part 5 cooperate with and connect the joint of support rod 1 and support head 2, first limit portion 4 and second limit portion 6 cooperate with and make the relative angle between support rod 1 and support head 2 be at the preset angle.

[0031] The engine cover support mechanism of the application comprises a support rod 1 and a support head 2, and the support rod 1 and the support head 2 are connected through clamping. Compared with the existing technology of plastic packaging, the application can effectively improve the injection molding efficiency. Specifically, the support rod 1 is provided with a first clamping part 3, and the support head 2 is provided with a second clamping part 5. The first clamping part 3 is clamped with the second clamping part 5, so as to realize the clamping connection of the support rod 1 and the support head 2. Further, the support rod 1 is provided with a first limiting part 4, and the support head 2 is provided with a second limiting part 6. The first limiting part 4 and the second limiting part 6 limit each other, so as to realize the fixed setting of the relative angle between the support rod 1 and the support head 2, that is, the first limiting part 4 and the second limiting part 6 cooperate to set the relative angle between the support rod 1 and the support head 2 at a preset angle, so as to facilitate the insertion of the support head 2 into the support hole 21 on the engine cover 19 at a specific angle to realize the limiting and wind-shedding functions of the support head 2. Since the support rod 1 and the support head 2 of the application are clamped and connected, only the support head 2 needs to be injection molded, and then the support head 2 is clamped and connected with the support rod 1. The support rod 1 and the support head 2 of the prior art need to be placed in the same mold for plastic packaging. Therefore, the plastic packaging cavity of the prior art is large in volume, and the injection molding mold is large in volume. The number of cavities provided in the same injection molding mold for the integral injection molding of the support rod 1 and the support head 2 is small. The application only needs to provide a cavity for the support head 2, and does not need to provide a cavity for the support rod 1. Therefore, the cavity required by the support head 2 is small, and the same volume of injection molding mold can provide a larger number of cavities for injection molding of the support head 2, which can effectively improve the injection molding efficiency. In addition, the application directly omits the step of placing the support rod 1 into the injection molding mold, and the application realizes quick assembly connection through the clamping of the support rod 1 and the support head 2. The quick assembly connection does not consume more time cost. Under the premise of ensuring the fixed relative angle of the support rod 1 and the support head 2 through the first limiting part 4 and the second limiting part 6, the overall injection molding efficiency can be effectively improved, and the production efficiency of the engine cover support mechanism is improved.

[0032] In one embodiment, the first clamping part 3 is a clamping groove or a clamping protrusion, the second clamping part 5 is a clamping protrusion or a clamping groove, and the clamping protrusion is clamped in the clamping groove.

[0033] The support rod 1 and the support head 2 are clamped and assembled through the first clamping part 3 and the second clamping part 5. Specifically, Figure 1 and Figure 7As shown, the first clamping part 3 is a clamping groove, the recess direction of the groove is along the radial direction of the support rod 1, the second clamping part 5 is a clamping protrusion, the protrusion direction of the clamping protrusion is along the radial direction of the support rod 1, the butt joint direction of the support rod 1 and the support head 2 is the axial direction, when the support rod 1 and the support head 2 are butt jointed in place along the butt joint direction, the clamping protrusion is just clamped in the clamping groove, not only realizing the clamping assembly connection of the support rod 1 and the support head 2, but also realizing the axial limiting of the support rod 1 and the support head 2 through the cooperation of the clamping protrusion and the clamping groove. In addition, the first clamping part 3 can be a clamping protrusion, and the second clamping part 5 can be a clamping groove, and the clamping protrusion is clamped in the clamping groove.

[0034] In one of the embodiments, the first limiting part 4 is a butt joint column or a butt joint groove, and the second limiting part 6 is a butt joint groove or a butt joint column, and the butt joint column is arranged in the butt joint groove.

[0035] The support rod 1 and the support head 2 are assembled and connected by clamping, and when the support rod 1 and the support head 2 are clamped in place, the first limiting part 4 and the second limiting part 6 are needed to limit the rotation freedom degree of the two along the axial direction. Specifically, the support rod 1 and the support head 2 need to be butt jointed, therefore, the first limiting part 4 on the support rod 1 is a butt joint column, and the second limiting part 6 on the support head 2 is a butt joint groove, and the butt joint column is inserted into the butt joint groove to realize the assembly connection of the support rod 1 and the support head 2. Further, the butt joint column as the first limiting part 4 on the support rod 1 and the butt joint groove as the second limiting part 6 on the support head 2, through the cooperation of the first limiting part 4 and the second limiting part 6, the relative angle of the support rod 1 and the support head 2 is set to a preset angle, therefore, as shown in Figure 4 and Figure 7 The cross sections of the butt joint column and the butt joint groove are both non-circular, and the cross sections of the butt joint column and the butt joint groove can be rectangular, oval, cross-shaped and special-shaped, as long as the rotation freedom degree of the butt joint groove around the axial direction can be limited by the butt joint column, so as to facilitate the support head 2 to be inserted into the support hole 21 on the engine cover 19 at a specific angle to realize the limiting and wind-shedding function of the support head 2. In addition, the first limiting part 4 on the support rod 1 can be a butt joint groove, and the second limiting part 6 on the support head 2 can be a butt joint column, and the butt joint column is inserted into the butt joint groove, which is equivalent to that the support head 2 is inserted into the support rod 1.

[0036] In one of the embodiments, the cross section shape of the butt joint column is consistent with the cross section shape of the butt joint groove, and the cross section size of the butt joint column is matched with the cross section size of the butt joint groove.

[0037] The cross section shape of the butt joint column is consistent with the cross section shape of the butt joint groove, as shown in Figure 7As shown, the cross-sectional shape of the docking column and the cross-sectional shape of the docking groove of the present application are both rectangular, and the cross-sectional size of the docking column is preferably slightly smaller than the cross-sectional size of the docking groove, so that the cross-sectional size of the docking column matches the cross-sectional size of the docking groove, enabling the docking column to be inserted into the docking groove, and effectively limiting the rotational freedom of the docking groove about its axis by the docking column. If Figure 4 the inner hole diameter of the docking groove is greater than the maximum size of the rectangular cross-section on the docking column, the docking column will be in a rotating state in the docking groove, and the relative angle between the support rod 1 and the support head 2 cannot be set to the preset angle by the cooperation of the docking column and the docking groove.

[0038] In one embodiment, the support head 2 is provided with a fixing groove 7, and the free end of a cantilever beam 8 provided on the groove wall of the fixing groove 7 extends towards the docking groove to form the clamping protrusion, which extends into the docking groove.

[0039] The clamping protrusion cooperates with the clamping groove to achieve clamping positioning of the support head 2 and the support rod 1, so the clamping protrusion needs to be a clamping protrusion with elasticity. Specifically, the circumferential side wall of the support head 2 is provided with a fixing groove 7, which can be a rectangular groove as shown in Figure 3 and Figure 5 A cantilever beam 8 is provided on one of the side walls of the rectangular groove, and the cantilever beam 8 extends towards the center line of the rectangular groove. In addition, the free end of the cantilever beam 8 extends towards the docking groove to form the clamping protrusion. Preferably, the free end of the cantilever beam 8 extends in the radial direction of the support head 2 to form the clamping protrusion, and the fixing groove 7 is in communication with the docking groove. The clamping protrusion extends into the docking groove, facilitating cooperation with the clamping groove on the support rod 1 for clamping. Further, as shown in Figure 6As shown, the side of the clamping protrusion close to the axis direction of the head clamping end 14 is the contact surface 16, and the side of the clamping protrusion away from the head clamping end 14 is the free surface 17. The wedge surface 18 is formed between the free surface 17 and the contact surface 16 at an inverse slope angle, which facilitates the sliding fit of the clamping protrusion and the mating column. Since the cantilever beam 8 has elastic deflection, the clamping protrusion is a clamping protrusion with elastic deformation. The mating process of the support rod 1 and the support head 2 is as follows: the mating column on the support rod 1 is inserted into the mating groove on the support head 2. During the insertion of the mating column into the mating groove, the mating column first contacts the wedge surface 18 on the clamping protrusion. The clamping protrusion is slowly lifted up through the sliding fit of the wedge surface 18 and the mating column, and the cantilever beam 8 is elastically deformed. At the same time, the contact surface 16 on the clamping protrusion is in contact and sliding with the cylindrical surface of the mating column. With the continuous insertion of the mating column, when the mating column is moved in place in the mating groove, the clamping protrusion is clamped into the clamping groove under the self-restoring force of elastic deformation, and the clamping assembly connection of the support head 2 and the support rod 1 is realized. In addition, two fixing grooves 7 can be provided, which are arranged at 180° about the axis 180° of the head clamping end 14. One of the fixing grooves 7 is used to set the clamping protrusion, and the other is used as a process groove to facilitate the realization of the casting process; or only one fixing groove 7 is designed to set the clamping protrusion, and the other is in a closed state.

[0040] In one embodiment, the top surface of the mating column forms a first positioning surface 9, and the groove bottom of the mating groove forms a second positioning surface 10. The first positioning surface 9 is in contact with the second positioning surface 10.

[0041] During the insertion of the mating column into the mating groove, the insertion of the mating column and the mating groove into place and the movement freedom of the support head 2 and the support rod 1 along the mating direction are realized through the cooperation of the first positioning surface 9 and the second positioning surface 10. Specifically, as shown in Figure 2As shown, the top surface of the butt joint column forms a first positioning surface 9, and the groove bottom of the butt joint groove forms a second positioning surface 10. The cooperation of the first positioning surface 9 and the second positioning surface 10 limits the movement freedom of the support head 2 and the support rod 1 in the butt joint direction. In addition, during the process of inserting the butt joint column into the butt joint groove, the butt joint column is continuously inserted into the butt joint groove. When the first positioning surface 9 on the butt joint column and the second positioning surface 10 on the head clamping end 14 come into contact, it indicates that the butt joint column is butt jointed in place in the butt joint groove. When the butt joint column is butt jointed in place in the butt joint groove, the clamping protrusion is clamped into the clamping groove under the self-recovery force of elastic deformation, realizing the clamping assembly connection of the support head 2 and the support rod 1. Therefore, the cooperation of the clamping protrusion and the clamping groove limits the movement freedom of the support head 2 and the support rod 1 in the butt joint direction, and the cooperation of the butt joint column and the butt joint groove limits the rotation freedom of the support head 2 and the support rod 1 around the axis thereof, realizing the stable and reliable clamping of the support rod 1 and the support head 2.

[0042] In one of the embodiments, the first positioning surface 9 is provided with a positioning groove 11, and the second positioning surface 10 is provided with a positioning protrusion 12, which is inserted into the positioning groove 11.

[0043] In order to further limit the rotation freedom of the support head 2 and the support rod 1 around the axis thereof and limit the movement freedom of the support head 2 in the radial direction on the support rod 1, as shown, Figure 2 As shown, the first positioning surface 9 on the butt joint column of the support rod 1 is provided with a positioning groove 11, and the second positioning surface 10 on the butt joint groove of the support head 2 is provided with a positioning protrusion 12. When the butt joint column is inserted into the butt joint groove in place, the positioning protrusion 12 is inserted into the positioning groove 11. Preferably, the positioning protrusion 12 and the positioning groove 11 are both rectangular, and the thickness of the positioning protrusion 12 is slightly smaller than the thickness of the positioning groove 11, so as to limit the rotation freedom of the support head 2 and the support rod 1 around the axis thereof and limit the movement freedom of the support head 2 in the radial direction on the support rod 1 through the cooperation of the positioning protrusion 12 and the positioning groove 11.

[0044] In one of the embodiments, the butt joint column forms a rod clamping end of the support rod 1, and the support rod 1 comprises a rod support end 13, which is integrally formed or detachably connected with the rod clamping end.

[0045] As shown, Figure 7As shown, the support rod 1 includes a rod engaging end and a rod support end 13. The rod engaging end of the support rod 1 is formed by the connecting post and is the end that engages with the support head 2 to achieve the connection between the support rod 1 and the support head 2. A support frame is provided on the vehicle, and the rod support end 13 is used to support the support frame to achieve the support connection between the support rod 1 and the support frame. The rod engaging end and the rod support end 13 are integrally formed or detachably connected. Preferably, the rod engaging end and the rod support end 13 are integrally formed.

[0046] In one embodiment, the support head 2 includes a head snap-fit ​​end 14 and a head support end 15, the mating groove is disposed on the head snap-fit ​​end 14, and the head snap-fit ​​end 14 and the head support end 15 are integrally formed.

[0047] like Figure 5 As shown, the support head 2 includes a head snap-fit ​​end 14, which is one end that snaps into the support rod 1 to connect the support rod 1 and the support head 2. A mating groove is provided on the head snap-fit ​​end 14 to facilitate the mating of the support head 2 and the support rod 1 through the cooperation of the mating post and the mating groove. The head support end 15 is one end that supports the engine hood 19. The engine hood 19 is provided with a support hole 21, and the head support end 15 is inserted into the support hole 21 to support the engine hood 19. The head snap-fit ​​end 14 and the head support end 15 are integrally injection molded.

[0050] The engine cover support mechanism is connected by the clamping mode of the support rod 1 and the support head 2, therefore, the application only needs to set the cavity for the support head 2, and does not need to set the cavity for the support rod 1, therefore, the cavity required by the support head 2 is smaller, the same volume of injection mold can set more number of cavities for injection molding the support head 2, and the injection efficiency can be effectively improved.
