Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of shell processing, in particular to an integrated processing device for a rearview mirror shell of an electric vehicle. BACKGROUND

[0002] In the prior art, the integrated processing of the rearview mirror shell of an electric vehicle usually relies on a five-axis linkage machining center as the core, an automatic manufacturing system integrating an industrial robot, a high-precision clamp and an online detection unit. The device aims to complete milling, drilling, insert fitting and other processes through one clamping to realize efficient and high-precision shell production.

[0003] In the above processing flow, for the cooling and setting link after the shell is injection molded, a built-in water cooling pipeline system in the mold is generally used for operation. Specifically, the cooling medium (usually water) circulates in the linear or simply connected pipeline drilled in the mold in advance, and the heat of the plastic melt is taken away through heat conduction, so as to realize the solidification and demolding of the product.

[0004] However, when carrying out cooling operation on workpieces such as the rearview mirror shell of an electric vehicle which has a complex structure and different wall thickness distribution, the water cooling pipeline of the existing cooling structure generally adopts a linear layout and is uniformly arranged outside the mold cavity, so that the cooling liquid in the cooling cavity inside the mold has the same residence time when flowing through the installation seat side with larger wall thickness and the thin-walled area of the shell. Since the installation seat side of the shell has a larger wall thickness, it accumulates more heat and requires a much longer cooling time than the thin-walled area. The existing cooling structure is not convenient for prolonging the residence time of the cooling liquid on the thickened side, and it is difficult to meet the differentiated cooling needs of different wall thickness areas, resulting in that the shell cannot be cooled synchronously, and the cooling of the thickened area is not thorough, which causes the shrinkage stress of each part of the shell to be unbalanced, and finally causes the shell to warp and deform.

[0005] Therefore, there is an urgent need for an integrated processing device for a rearview mirror shell of an electric vehicle to solve the above problems. SUMMARY

[0006] The present application provides an integrated processing device for a rearview mirror shell of an electric vehicle, which sets the mold as a combined structure of a front cavity shell and a rear cooling shell, fills the cooling liquid in the communication cavity between the front cavity shell and the rear cooling shell, and sets a flow guide assembly with a hole piece, a rotating assembly and a swinging assembly in the rear cooling shell. When the cooling liquid flows through the hole piece, the rotating assembly is driven to rotate to form a rotational flow to prolong the residence time of the cooling liquid in the thickened area, and the fluctuating cooling liquid drives the swinging assembly to swing to enhance the overall turbulent flow, realizing differentiated and uniform cooling of different wall thickness areas of the shell, thereby solving the problems raised in the above background art, i.e. The existing cooling structure cannot extend the residence time of coolant on the thickened side of the shell, making it difficult to meet the differentiated cooling needs of different wall thickness areas. This results in the shell not being cooled synchronously and the thickened area not being cooled thoroughly, which in turn causes the shell to warp and deform.

[0007] To achieve the above objectives, the integrated processing device for the rearview mirror housing of the electric vehicle includes an injection molding device, the end of which is provided with a molding device, and the molding device contains multiple molds, the molds including a front cavity shell and a rear cold shell; The front cavity shell has a cavity on its front side that is adapted to the shape of the electric vehicle rearview mirror shell. The rear side of the front cavity shell has a hollow structure and is fixedly connected to the rear cooling shell. The rear cooling shell is a hollow shell. The hollow structure of the front cavity shell is connected to the internal cavity of the rear cooling shell and is filled with coolant together. A flow guiding component is fixedly installed inside the rear cooling shell, and an annular flow channel is formed between the flow guiding component and the inner wall of the rear cooling shell to guide the coolant to circulate between the front cavity shell and the rear cooling shell. The flow guiding component is provided with a plurality of holes and a swinging component distributed along its axial direction. Each hole is provided with a rotatable rotating component. When the coolant flows through the hole, it drives the rotating component to rotate, so that the coolant flowing through it forms a swirling flow, thereby prolonging the local residence time of the coolant in the hole area. When the coolant fluctuates due to the swirling effect, the oscillating component is oscillated by the fluid excitation, which enhances the overall turbulence of the coolant.

[0008] In the above technical solution, because there are differences in wall thickness in the rearview mirror housing of electric vehicles, the thickened area (such as the mounting base) accumulates more heat and requires a much longer cooling time than the thin-walled area. Since the existing cooling structure cannot achieve differentiated cooling, the mold is set as a connected structure between the front cavity shell and the rear cold shell and filled with coolant. A flow guiding component is set in the rear cold shell to form an annular flow channel to guide the coolant to circulate in an orderly manner and avoid the occurrence of cooling dead zones. The reason for setting the perforated part to correspond to the thickened area of ​​the housing is that when the coolant flows through the perforated part, it will drive the rotating component to rotate and form a swirling flow. The swirling flow can prolong the local residence time of the coolant in the thickened area, ensuring that the heat in the thickened area is fully carried away. The reason for setting up the swing component in the thin-walled area is that the oscillation generated by the swirling flow will drive the swing component to swing, which will enhance the overall turbulence of the coolant and allow the coolant to flow more fully in the thin-walled area, thus avoiding local overheating. The combination of extending the residence time in the thickened area by the swirling flow and enhancing the overall turbulence by the swing will achieve differentiated and uniform cooling of areas with different wall thicknesses, ensuring that all parts of the shell are cooled synchronously.

[0009] On this basis, the flow guide assembly comprises a special-shaped plate and a support, the special-shaped plate is fixedly connected with the support, the support is fixedly installed on the inner wall of the rear cooling shell, a plurality of hole members are arranged on the special-shaped plate, and a plurality of swing assemblies are arranged on the outer surface of the side of the special-shaped plate facing the front cavity shell.

[0010] Preferably, the overall profile of the special-shaped plate is matched with the outer profile of the rear-view mirror shell of the electric vehicle, and a ring-shaped flow channel is formed between the outer peripheral surface of the special-shaped plate and the inner wall of the rear cooling shell.

[0011] A plurality of hole members are arranged on the special-shaped plate and correspond to positions of regions with large wall thickness in the rear-view mirror shell of the electric vehicle, and a plurality of swing assemblies are arranged on the special-shaped plate and correspond to positions of regions with small wall thickness in the rear-view mirror shell of the electric vehicle.

[0012] In another technical solution, the hole member comprises a rotating flow port, a middle port and a liquid outlet port, the middle port is located between the rotating flow port and the liquid outlet port, and a rotating assembly is arranged in the middle port.

[0013] Preferably, the rotating flow port and the liquid outlet port are both conical hole structures, and the small-diameter ends thereof are connected with the middle port, and the middle port is a cylindrical straight flow channel structure.

[0014] The rotating assembly comprises a rotating cylinder, a circular ring is fixedly connected to the outer wall of the rotating cylinder, the circular ring and the rotating cylinder are movably connected to the inner wall of the middle port, and a plurality of vanes are fixedly connected to the inner wall of the rotating cylinder.

[0015] Preferably, the leading flow side edge of the vane is provided with a flow guide inclined surface, and all the vanes are fixed to the inner wall of the rotating cylinder in an inclined manner relative to the axis of the rotating cylinder.

[0016] In the above technical solution, the swing assembly comprises two stop blocks movably fixed to the special-shaped plate, a support rod fixed to the special-shaped plate is arranged between the two stop blocks, a rotating rod is movably sleeved to the outer wall of the support rod, and a blade is fixedly connected to the outer wall of the rotating rod.

[0017] Preferably, the blade is made of soft silica gel material, and the blade is located in the gap between the two stop blocks and can drive the rotating rod to swing around the axis of the support rod to conform to and amplify the fluctuation of the cooling liquid.

[0018] Compared with the prior art, the beneficial effects of the present application are: 1. By setting the mold as a communication structure of the front cavity shell and the rear cooling shell and filling the cooling liquid, a ring-shaped flow channel is formed by cooperating with the flow guide assembly fixed in the rear cooling shell to guide the cooling liquid to circulate between the front and rear cavity shells in an orderly manner, and the differential flow control of the cooling liquid in different wall thickness regions of the shell body is realized by the corresponding layout of the hole members and the swing assemblies on the flow guide assembly, so that the cooling rates of the regions are balanced.

[0019] 2. By setting the rotating assembly with inclined blades in the hole member, the driving force of the cooling liquid is used to drive the blades and the rotating drum to rotate, so that the cooling liquid flowing through the thickening area forms a rotating flow, prolongs the residence time of the cooling liquid in the thickening area, ensures that the heat of the thick wall part is fully dissipated, and the fluctuation generated by the rotating flow drives the swing assembly in the thin wall area to swing, further enhances the overall turbulent degree of the cooling liquid, ensures that the cooling of the thin wall area is sufficient, and the linkage of the rotating assembly and the swing assembly strengthens the overall heat exchange effect and improves the cooling efficiency.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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] Currently, in the cooling process of rearview mirror housings, the coolant's residence time in different heat load areas is the same, which cannot meet the differentiated cooling requirements, leading to an imbalance of shrinkage stress and warping deformation in the housing. This invention provides an integrated processing device for electric vehicle rearview mirror housings. (See attached image.) Figures 1-2 As shown, it includes an injection molding device, with a molding device 1 at one end. The molding device 1 contains multiple molds 11, such as... Figure 3 As shown, the mold 11 includes a front cavity shell 110 and a rear cooling shell 111; The front cavity shell 110 has a cavity on the front side that is adapted to the shape of the electric vehicle rearview mirror shell. The rear side of the front cavity shell 110 has a hollow structure and is fixedly connected to the rear cooler shell 111. The rear cooler shell 111 is a hollow shell. The hollow structure of the front cavity shell 110 is connected to the internal cavity of the rear cooler shell 111 and is filled with coolant together. See Figure 4 As shown, a flow guiding assembly 12 is fixedly installed inside the rear cooling shell 111. An annular flow channel is formed between the flow guiding assembly 12 and the inner wall of the rear cooling shell 111 to guide the coolant to circulate between the front cavity shell 110 and the rear cooling shell 111. The flow guiding assembly 12 is provided with a plurality of holes 13 and swinging assemblies 15 distributed along its axial direction. Each hole 13 is provided with a rotatable rotating assembly 14.

[0024] See Figure 5 and Figure 6 As shown, during processing, the injection molding device injects molten raw material into the cavity of the front shell 110 of the mold 11 inside the molding device 1. The cavity is adapted to the shape of the electric vehicle rearview mirror shell to complete the initial molding of the shell. At this time, the coolant filled in the hollow structure of the front shell 110 and the internal cavity of the rear cold shell 111 begins to play a cooling role. The annular flow channel formed by the fixed flow guide component 12 inside the rear cold shell 111 and the inner wall of the rear cold shell 111 guides the coolant to circulate orderly between the front shell 110 and the rear cold shell 111. When the cooling liquid flows through the hole piece 13 on the flow guide assembly 12, it will drive the rotating assembly 14 in the hole piece 13 to rotate, so that the cooling liquid flowing through the place forms a rotational flow, thereby prolonging the local residence time of the cooling liquid in the corresponding area of the hole piece 13, and ensuring that the heat of the thickened area of the shell can be fully taken away; after the cooling liquid fluctuates due to the rotational flow, it flows through the swing assembly 15 on the flow guide assembly 12 and generates fluid excitation, which promotes the swing assembly 15 to swing and enhances the overall turbulent degree of the cooling liquid, thereby ensuring sufficient cooling of the thin-walled area of the shell. Ultimately, through the cooperative action of the circulation flow of the cooling liquid, the prolonged residence time of the rotational flow, and the enhanced turbulence of the swing, uniform cooling of different wall thickness areas of the shell is realized, and the forming quality of the shell is ensured.

[0025] Specifically, referring to Figure 7 As shown, the flow guide assembly 12 is fixedly installed with the inner wall of the rear cooling shell 111 through the support 121, wherein the overall profile of the special-shaped plate 120 is adapted to the outer profile of the electric vehicle rearview mirror shell in the front cavity shell 110, and this adaptive design enables the outer peripheral surface of the special-shaped plate 120 to form an annular flow channel around the special-shaped plate 120 between the inner wall of the rear cooling shell 111, thereby providing a circulating flow path for the cooling liquid and ensuring that the cooling liquid can smoothly and comprehensively flow between the front cavity shell 110 and the rear cooling shell 111. At the same time, the hole piece 13 and the swing assembly 15 on the special-shaped plate 120 are arranged in a targeted manner, wherein the hole piece 13 is arranged in an array at a position corresponding to a larger wall thickness area of the electric vehicle rearview mirror shell, and the swing assembly 15 is arranged at a position corresponding to a smaller wall thickness area of the shell. When the cooling liquid flows through the annular flow channel, it will flow through the hole piece 13 and the swing assembly 15 on the special-shaped plate 120. The hole piece 13 can cooperate with the internal rotating assembly 14 to form a rotational flow of the cooling liquid in the thickened area to prolong the residence time, and the swing assembly 15 can swing under the fluctuation of the cooling liquid to enhance the turbulence. Through this precise adaptive structure layout and component cooperation, differential cooling control of different wall thickness areas of the shell is realized.

[0026] It should be particularly noted that the cooling circulation device in the prior art has the water outlet and the water inlet of the cooling liquid integrated and installed inside the support 121 of the mold 11, and the ends of the water outlet and the water inlet are both provided on the special-shaped plate 120. At the same time, a one-way valve is installed inside the water outlet and the water inlet. The cooling liquid flows into the inside of the device from the tail of the support 121, flows through the internal channel of the support 121, and then flows into the cooling cavity of the mold 11 through the water inlet on the special-shaped plate 120 in a one-way manner. After completing the cooling and heat exchange of the cavity, the cooling liquid flows back to the internal channel of the support 121 through the water outlet on the special-shaped plate 120 in a one-way manner, and finally flows out from the tail of the support 121, thereby completing the one-way circulation supply of the cooling liquid.

[0027] In implementation, referring to Figure 8As shown, in actual implementation, the cooling liquid first enters the cyclone port 130 of the hole piece 13 during circulation between the front cavity shell 110 and the rear cavity shell 111; since the cyclone port 130 adopts a tapered hole structure, and the small-diameter end thereof is connected with the middle through port 131, the cooling liquid realizes flow rate increase during flow through the cyclone port 130 along with the contraction of the hole diameter of the tapered hole, and simultaneously forms a preliminary flow guiding effect, and stably enters the middle through port 131 as a cylindrical straight flow channel structure; As shown in Figure 9 The rotating assembly 14 arranged inside the middle through port 131 rotates under the driving force of the high-speed flowing cooling liquid, and drives the cooling liquid flowing through the middle through port 131 to form a cyclone effect; at this time, the cooling liquid with the cyclone effect flows out of the hole piece 13 through the outlet port 132 which is also a tapered hole structure and has a small-diameter end connected with the middle through port 131; the rotating flow cooling liquid is guided to flow into the overall circulation flow channel through the tapered structure of the outlet port 132, and the residence time of the cooling liquid in the corresponding area of the hole piece 13 is prolonged by means of the cyclone effect in the middle through port 131, so as to ensure that the heat of the thickened area of the shell is fully taken away.

[0028] In the embodiment, as shown in Figure 9 and Figure 10 The rotating assembly 14 is movably connected with the inner wall of the middle through port 131 of the hole piece 13 through the ring 141 fixed to the outer wall of the rotating drum 140, so as to ensure that the rotating drum 140 can stably rotate in the middle through port 131 without deviation; when the cooling liquid enters the middle through port 131 after being accelerated by the flow guiding of the cyclone port 130 of the hole piece 13, the cooling liquid directly impacts the fan blades 142 fixed to the inner wall of the rotating drum 140; Since the leading flow side edge of the fan blades 142 is provided with a flow guiding slope, and all the fan blades 142 are arranged in a manner inclined relative to the axis of the rotating drum 140, when the cooling liquid flows through the middle through port 131 in the axial direction, the impact force direction is originally parallel to the axis of the rotating drum 140, that is, the axial direction; if the fan blades 142 are flat structures perpendicular to the axis, the axial impact force can only act on the surface of the fan blades 142 to generate pressure, and cannot drive the fan blades 142 to rotate; However, the fan blades 142 in the technical solution are inclined relative to the axis of the rotating drum 140, so that the surface of the fan blades 142 forms a certain inclined angle with the axial flow direction of the cooling liquid; when the cooling liquid impacts the fan blades 142, the cooling liquid can generate pressure perpendicular to the surface of the fan blades 142 and friction force along the surface of the fan blades 142; At this time, the guide slope can guide the cooling liquid to flow along the slope, convert part of the axial flow momentum into tangential momentum, thereby enhancing the tangential driving force on the fan blades 142, concentrating the originally dispersed fluid impact force in the inclined direction of the fan blades 142, so that the pressure perpendicular to the surface of the fan blades 142 is decomposed into two components, one forms a component along the radial direction of the rotating drum 140, which is offset by the limiting structure of the inner wall of the middle opening 131, to avoid the deviation of the rotating drum 140, and the other forms a tangential component along the circumferential direction of the rotating drum 140; And the tangential component provides a driving force for the fan blades 142 to rotate around the axis of the rotating drum 140, as shown in Figure 11 Since the plurality of fan blades 142 are fixed in the same inclined direction on the inner wall of the rotating drum 140, the tangential components generated by the cooling liquid on each fan blade 142 form a synergistic effect, driving the fan blades 142 to rotate synchronously, and further driving the rotating drum 140 fixedly connected with the fan blades 142 to rotate around its own axis; The rotation of the rotating drum 140 disturbs the cooling liquid in the middle opening 131, making the cooling liquid form a stable and strong rotational flow, prolonging the residence time of the cooling liquid in the middle opening 131 and the thickened area of the corresponding shell, thereby fully absorbing the heat of the thick-walled area and ensuring the differentiated cooling effect.

[0029] In addition, as shown in Figure 12 The swing assembly 15 includes two blocks 150, a support rod 151 is arranged between the two blocks 150, a rotating rod 152 is movably sleeved on the outer wall of the support rod 151, and a blade 153 is fixedly connected to the outer wall of the rotating rod 152; The two blocks 150 are fixed relative to the special-shaped plate 120, the support rod 151 between the two blocks 150 is also fixed on the special-shaped plate 120, the rotating rod 152 is movably sleeved on the outer wall of the support rod 151, so that the rotating rod 152 can flexibly rotate around the axis of the support rod 151, and the blade 153 fixedly connected with the rotating rod 152 is located in the gap between the two blocks 150; During the cooling process, when the cooling liquid flows through the rotating assembly 14 in the hole piece 13 to form a rotational flow and generate fluctuations, the fluctuating cooling liquid will act on the blade 153 made of soft silica gel material; According to the low rigidity and good elastic deformation ability of the soft silica gel material itself, when the fluctuating cooling liquid acts on the surface of the blade 153, the impact force of the cooling liquid will generate a force directed to the fluctuation direction on the blade 153, and since the silica gel material does not have the anti-deformation ability of rigid materials, the blade 153 will be bent and deformed in the fluctuation direction under the action of the force, and this deformation is reversible; When the fluctuation direction of the cooling liquid changes or the impact force disappears, the silica gel blade 153 will restore to the initial state by its own elasticity, and then drive the rotating rod 152 fixedly connected therewith to reciprocating swing around the shaft of the supporting rod 151; compared with the defect that the blade 153 made of rigid material is easily damaged by fluid impact or cannot respond to fluid fluctuation, the flexible characteristic of soft silica gel not only ensures the sensitive response of the blade 153 to the fluctuation of the cooling liquid, but also buffers the fluid impact through its own elasticity; At the same time, since the blade 153 needs to keep reciprocating swing and cannot rotate, the two blocks 150 limit the swing range of the blade 153, avoiding damage of the blade 153 due to too large swing amplitude, and avoiding rotation of the blade 153, so as to ensure that the blade 153 always keeps reciprocating motion in the preset swing range; Specifically, since the design purpose of the blade 153 is to disturb the surrounding cooling liquid through its own motion, amplify the fluid fluctuation caused by the rotating flow, and then enhance the overall turbulence degree of the cooling liquid, if the blade 153 rotates, it generates directional fluid driving force along the rotation direction, which is easy to form local vortex of the cooling liquid, which will destroy the ordered circulation of the cooling liquid in the annular flow channel, and cannot realize the target of uniformly disturbing the fluid; the reciprocating swing of the blade 153 under the limitation of the block 150 can form regular disturbance to the cooling liquid from different directions. This disturbance is moderate and uniform, which can effectively amplify the fluctuation amplitude of the cooling liquid, promote the cooling liquid in the thin-walled area to form strong turbulence, improve the heat exchange efficiency between the cooling liquid and the cavity wall, and at the same time, the motion form of reciprocating swing is suitable for the fluctuation direction of the cooling liquid, which is more in line with the rhythm of fluid fluctuation, and ensures that the thin-walled area is cooled fully and uniformly; By reciprocating swing of the blade 153, the surrounding cooling liquid is disturbed, the overall fluctuation degree of the cooling liquid is amplified, the cooling liquid forms stronger turbulence, and the flow uniformity and heat exchange efficiency of the cooling liquid in the thin-walled area are improved, so as to ensure that the thin-walled area of the shell is cooled fully.

[0030] Working principle: When processing, the injection molding device injects the raw material in molten state into the front cavity shell 110 of the mold 11 in the molding device 1, and the cavity is matched with the molding of the rearview mirror shell of the electric vehicle, so as to complete the preliminary molding of the shell; after the preliminary molding of the shell, the hollow structure of the front cavity shell 110 and the cooling liquid filled in the internal cavity of the rear cold shell 111 immediately play a cooling role, and under the guidance of the annular flow channel formed by the flow guiding assembly 12 and the inner wall of the rear cold shell 111, the cooling liquid flows orderly in the front cavity shell 110 and the rear cold shell 111; At this time, the cooling liquid flows through the hole piece 13 on the flow guide assembly 12 in the circulating flow process, first realizes the flow rate promotion and preliminary flow guide through the spiral flow port 130 of the conical structure, and then smoothly enters the middle through port 131; the cooling liquid flowing at high speed impacts the fan blade 142 of the rotating assembly 14 in the middle through port 131, the flow guide slope of the flow-impingement side of the fan blade 142 is arranged obliquely relative to the axis of the rotating cylinder 140, the flow guide slope can guide the cooling liquid to flow along the slope, convert part of the axial flow momentum into tangential momentum, thereby enhancing the tangential driving force borne by the fan blade 142, driving the rotating cylinder 140 and the fan blade 142 to rotate synchronously, and further driving the cooling liquid flowing therethrough to form stable spiral flow; the cooling liquid in the spiral flow state is collected into the overall flow channel through the liquid outlet 132 of the conical structure, and the residence time of the cooling liquid in the thickened area of the hole piece 13 corresponding to the shell is prolonged through the spiral flow effect, so that the heat in the area is fully absorbed and taken away; The cooling liquid naturally produces fluctuation after the spiral flow effect, the fluctuating cooling liquid immediately flows through the swing assembly 15 on the flow guide assembly 12 and acts on the blade 153 of the soft silica gel material; the blade 153 reversibly deforms in the fluctuation direction of the cooling liquid by virtue of the flexible property of the blade 153, thereby driving the rotating rod 152 to reciprocating swing around the shaft line of the supporting rod 151, and the two stop blocks 150 simultaneously limit the blade 153, avoiding that the swing amplitude of the blade 153 is too large or that the blade 153 rotates, and ensuring that the blade 153 always moves in the preset mode; The surrounding cooling liquid is disturbed through the reciprocating swing of the blade 153, the overall fluctuation degree of the cooling liquid is amplified, the cooling liquid in the thin-walled area forms strong turbulent flow, the heat exchange efficiency of the cooling liquid and the cavity wall is improved, and the cooling of the thin-walled area is ensured to be sufficient; Finally, through the synergistic effect of the ordered circulation of the cooling liquid, the prolonged residence time of the spiral flow in the thickened area, and the swing of the thin-walled area, the differential uniform cooling of different wall thickness areas of the shell is realized, the shrinkage stress of each part of the shell is ensured to be consistent, and thus the forming quality of the electric vehicle rearview mirror shell is ensured.
