Description

Technical Field

[0001] This application relates to the field of automotive metal connector technology, and more particularly, to a metal connector for new energy vehicles. Furthermore, this application also relates to a processing apparatus for the aforementioned metal connector for new energy vehicles. Background Technology

[0002] The information provided in this section is for the purpose of generally presenting the background of this application. To the extent described in this section, the work of the currently named inventors and aspects of the description that may not constitute prior art at the time of filing are neither explicitly nor implicitly considered to be prior art of this application.

[0003] In recent years, the development of new energy vehicles has been rapid, and the corresponding supporting component technologies have become increasingly advanced. Metal connecting plates are a common type of connector in the automotive industry. Existing metal connecting plates are composed of a first metal plate and a second metal plate stacked on top of each other. However, during long-term use, it has been found that the stacked metal connecting plates are prone to misalignment, leading to connection failure.

[0004] In addition, the processing equipment for metal connecting pieces mainly requires a stamping device. For example, Chinese Patent Publication No. CN116978879A discloses a metal connecting piece with a buffer function and its stamping equipment, which includes a stamping frame, a first driving device and a second driving device. The driving device is fixedly connected to one side of the stamping frame. The output end of the first driving device is fixedly connected to a first stamping head, and the output end of the second driving device is fixedly connected to a second stamping head. One end of the second stamping head is fixedly connected to a cutting plate. One side of the first stamping head is fixedly connected to a first stamping part. One end of the first stamping part is fixedly connected to a slotting part. A second stamping part is provided on one side of the slotting part. A slotting mechanism is fixedly connected to one side of the second stamping part. The other end of the first stamping part is fixedly connected to an air pump. The suction end of the air pump is connected to an adsorption mechanism. An installation groove is opened on the stamping table of the stamping frame. A mold mechanism is fixedly connected inside the installation groove. The stamping equipment can efficiently complete the stamping processing of metal connecting pieces.

[0005] However, existing stamping equipment tends to accumulate impurities on the upper surface of the lower die after long-term use, requiring frequent manual cleaning to avoid affecting the stamping process. This increases the workload of workers and reduces processing efficiency.

[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art.

An air inlet pipe is provided at the bottom of the limiting guide, and a one-way air inlet valve is provided on the air inlet pipe. The air blowing assembly is disposed on the outer wall of the limiting guide and communicates with the limiting cavity. The pressure block assembly is used to abut against and push the piston assembly when the upper die approaches the lower die to compress the air in the limiting cavity and exhaust it through the air blowing assembly to blow clean the surface of the lower die.

[0011] In some embodiments of this application, the air blowing assembly includes a first air blowing pipe and a second air blowing pipe, which are connected to the limiting cavity. Both the first and second air blowing pipes are provided with a one-way air outlet valve. The air outlets of the first and second air blowing pipes are inclined downward and face the adjacent sides of the lower mold, respectively.

[0012] In some embodiments of this application, both the first air pipe and the second air pipe include a flexible hose. The processing device for the metal connecting piece of the new energy vehicle also includes a pushing component. The pushing component is disposed on the outer wall of the sleeve. The pushing component is used to abut and push the first air pipe and the second air pipe when the upper mold approaches the lower mold, thereby causing the air outlets of the first air pipe and the second air pipe to be offset and rotated to the outside of the lower mold, respectively.

[0013] In some embodiments of this application, the pushing component includes a connecting plate, a second connecting rod, and a pushing member. The connecting plate is connected to the outer wall of the sleeve. The second connecting rod is disposed at the bottom of the connecting plate. The pushing member is disposed at the bottom end of the second connecting rod. The pushing member includes a first pushing plate and a second pushing plate connected to each other. The first pushing plate and the second pushing plate are used to abut against and push the first air pipe and the second air pipe respectively when the upper mold approaches the lower mold.

[0014] In some embodiments of this application, both the first push plate and the second push plate have a structure that is wider at the top and narrower at the bottom, and the side wall of the first push plate that abuts against the first air tube has a beveled structure, and the side wall of the second push plate that abuts against the second air tube has a beveled structure.

[0015] In some embodiments of this application, the pressure block assembly includes a first connecting rod and a pressure block. The top end of the first connecting rod is connected to the bottom of the upper mold, and the pressure block is disposed at the bottom end of the first connecting rod. The first connecting rod is used to drive the pressure block to extend into the limiting cavity of the limiting guide and abut against the piston assembly when the upper mold approaches the lower mold.

[0016] In some embodiments of this application, the piston assembly includes a piston member and a compression spring, the compression spring being disposed within a limiting cavity, the piston member being disposed at the top of the compression spring and positioned above the air blowing assembly.

[0017] In some embodiments of this application, a limiting block is provided on the inner wall of the limiting cavity, and the limiting block is located above the air blowing assembly.

[0018] In some embodiments of this application, a ring of barriers is provided on the upper surface of the lower die, which surrounds the stamping groove. A collection frame is provided around the lower die to collect impurities falling from the surface of the lower die.

[0019] This application has the following beneficial effects: This application's new energy vehicle metal connecting piece achieves mutual restraint between the first and second connecting pieces through the concave-convex structure in the middle, effectively enhancing the connection stability of the first and second connecting pieces and significantly reducing phenomena such as mutual sliding and displacement between them. Specifically, the first connecting piece has a first concave portion and a first convex portion in the middle, and the second connecting piece has a second concave portion and a second convex portion in the middle corresponding to the first concave portion and the first convex portion. The first concave portion engages with the second concave portion, thus achieving the second concave portion enveloping and restraining the first concave portion; similarly, the second convex portion engages with the first convex portion, thus achieving the first convex portion enveloping and restraining the second convex portion. This significantly reduces the likelihood of the first and second connecting pieces shifting from each other.

[0020] The processing device for metal connecting pieces for new energy vehicles in this application also has the aforementioned beneficial effects. It further includes the ability to specifically stamp metal connecting pieces and promptly blow away impurities remaining on the upper surface of the lower die, reducing manual cleaning workload, preventing impurities from affecting the stamping process, and effectively improving the quality of stamping. The limiting guide on the lower die not only cooperates with the sleeve of the upper die to guide and limit the upper die as it approaches the lower die, but the pressure block assembly inside the sleeve also abuts against and pushes the piston assembly inside the limiting cavity of the limiting guide. This allows the piston assembly to compress the air in the limiting cavity and then exhaust it through the air blowing assembly to blow away air from the surface of the lower die. This achieves air blowing and cleaning of the lower die surface simultaneously with the stamping process, promptly removing impurities and effectively ensuring the cleanliness of the lower die surface, reducing frequent machine shutdowns for cleaning, and improving processing efficiency.

In addition to the purposes, features, and advantages described above, this application also has other purposes, features, and advantages.

Detailed Implementation

[0023] The embodiments of this application are described in detail below with reference to the accompanying drawings; however, this application may be implemented in a variety of different ways as defined and covered below.

[0024] Figure 1 This is a schematic diagram of the overall structure of the metal connecting piece according to a preferred embodiment of this application; Figure 2 This is a schematic diagram of the overall structure of the metal connecting piece processing apparatus according to a preferred embodiment of this application; Figure 3 This is a schematic diagram of the installation of the pusher component according to a preferred embodiment of this application; Figure 4 This is a schematic diagram of the piston assembly according to a preferred embodiment of this application; Figure 5 This is a schematic diagram of the structure of the pressing block assembly according to a preferred embodiment of this application; Figure 6 This is a schematic diagram of the air blowing assembly according to a preferred embodiment of this application; Figure 7 This is a schematic diagram of the structure of the driving component according to a preferred embodiment of this application.

[0025] A new energy vehicle metal connecting piece includes a first connecting piece 100 and a second connecting piece 200 stacked and connected vertically. Insulating double-sided adhesive is provided between the first connecting piece 100 and the second connecting piece 200. The first connecting piece 100 has first leads 102 at opposite ends, and the second connecting piece 200 has second leads 202 at opposite ends. The first connecting piece 100 has vertical first support portions 101 at opposite ends, with the first leads 102 located at the top of the first support portions 101. The second connecting piece 200 has... The first connecting piece 100 has a first recessed portion 103 and a first convex portion 104 in the middle. The second connecting piece 200 has a second recessed portion 203 and a second convex portion 204 in the middle, which correspond to the first recessed portion 103 and the first convex portion 104. The second connecting piece 200 has a second recessed portion 203 and a second convex portion 204 in the middle, which are corresponding to the first recessed portion 103 and the first convex portion 104. The second recessed portion 203 is used to wrap and limit the first recessed portion 103, and the first convex portion 104 is used to wrap and limit the second convex portion 204.

[0026] It should be noted that the two ends of the first connecting piece 100 and the second connecting piece 200 are staggered so that the first pin 102 and the second pin 202 are staggered to achieve different connection point functions.

[0027] This application's new energy vehicle metal connecting piece achieves mutual restraint between the first connecting piece 100 and the second connecting piece 200 through the concave-convex structure in the middle, effectively enhancing the connection stability of the first connecting piece 100 and the second connecting piece 200 and significantly reducing phenomena such as mutual sliding and displacement between them. Specifically, the first connecting piece 100 has a first recessed portion 103 and a first convex portion 104 in its middle, and the second connecting piece 200 has a second recessed portion 203 and a second convex portion 204 in its middle, corresponding to the first recessed portion 103 and the first convex portion 104. The first recessed portion 103 is inserted into the second recessed portion 203, thus achieving restraint and limiting of the first recessed portion 103. Similarly, the second convex portion 204 is inserted into the first convex portion 104, achieving restraint and limiting of the second convex portion 204 by the first convex portion 104. This significantly reduces the likelihood of mutual displacement between the first connecting piece 100 and the second connecting piece 200.

[0028] According to another aspect of this application, a processing apparatus for metal connecting pieces of new energy vehicles is also provided, applied to the processing of the aforementioned metal connecting pieces of new energy vehicles. The processing apparatus for metal connecting pieces of new energy vehicles includes a lower mold 1, an upper mold 2, a sleeve 3, a pressing block assembly, a piston assembly, a limiting guide 4, and an air blowing assembly 5. A stamping groove 10 is provided on the lower mold 1, the limiting guide 4 is disposed on the top surface of the lower mold 1, and the sleeve 3 is disposed on the bottom surface of the upper mold 2. The sleeve 3 is used to be sleeved on the limiting guide when the upper mold 2 is close to the lower mold 1. The upper mold 2 is guided and limited by the limiting guide 4. The pressure block assembly is set inside the sleeve 3. A limiting cavity is opened in the limiting guide 4. A piston assembly is set in the limiting cavity. An air inlet pipe 7 is set at the bottom of the limiting guide 4. A one-way air inlet valve is set on the air inlet pipe 7. The air blowing assembly 5 is set on the outer wall of the limiting guide 4 and communicates with the limiting cavity. The pressure block assembly is used to abut against and push the piston assembly when the upper mold 2 approaches the lower mold 1, so as to compress the air in the limiting cavity and blow it out through the air blowing assembly 5 to clean the surface of the lower mold 1.

[0029] Here, "limiting guide 4" refers to a structure vertically disposed on the surface of the lower mold 1. In some embodiments, the limiting guide 4 is a cylindrical structure with a limiting cavity inside, and the limiting guide 4 is slidably connected to the sleeve 3. Preferably, the limiting guide 4 is arranged diagonally or in an array to provide a stable limiting and guiding function.

[0030] The processing device for metal connecting pieces of new energy vehicles in this application also has the aforementioned beneficial effects. It also includes the ability to specifically stamp metal connecting pieces and promptly blow away impurities remaining on the upper surface of the lower die 1, reducing the workload of manual cleaning, preventing impurities from affecting the stamping process, and effectively improving the quality of stamping. The limiting guide 4 on the lower die 1 not only cooperates with the sleeve 3 of the upper die 2 to guide and limit the upper die 2 as it approaches the lower die 1, but the pressure block assembly inside the sleeve 3 can also abut against and push the piston assembly inside the limiting cavity of the limiting guide 4. This allows the piston assembly to compress the air in the limiting cavity and then exhaust it through the air blowing assembly 5 to blow away air from the surface of the lower die 1. This achieves air blowing and cleaning of the surface of the lower die 1 simultaneously with the stamping process, promptly removing impurities from the surface of the lower die 1, effectively ensuring the cleanliness of the lower die 1 surface, reducing frequent machine shutdowns for cleaning, and improving processing efficiency.

[0031] Preferably, please refer to Figure 6 As shown, the air blowing assembly 5 includes a first air blowing pipe 51 and a second air blowing pipe 52. The first air blowing pipe 51 and the second air blowing pipe 52 are connected to the limiting cavity. One-way air outlet valves are provided on the first air blowing pipe 51 and the second air blowing pipe 52. The air outlets of the first air blowing pipe 51 and the second air blowing pipe 52 are inclined downward and face the adjacent sides of the lower mold 1 respectively.

[0032] It is understood that the air outlets of the first air pipe 51 and the second air pipe 52 are respectively oriented towards different directions on the upper surface of the lower mold 1, so as to provide a wider range of air blowing coverage on the upper surface of the lower mold 1. In some embodiments, the projected center lines of the first air pipe 51 and the second air pipe 52 are arranged perpendicular to each other to reduce the mutual influence of air blowing between the first air pipe 51 and the second air pipe 52.

[0033] Preferably, please refer to Figure 6 and 7 As shown, both the first air pipe 51 and the second air pipe 52 include hoses. The processing device for the metal connecting piece of the new energy vehicle also includes a pushing component 6. The pushing component 6 is disposed on the outer wall of the sleeve 3. The pushing component 6 is used to abut and push the first air pipe 51 and the second air pipe 52 when the upper mold 2 is close to the lower mold 1, thereby causing the air outlets of the first air pipe 51 and the second air pipe 52 to be offset and rotated to the outside of the lower mold 1 respectively.

[0034] Understandably, since both the first air pipe 51 and the second air pipe 52 are made of flexible hose, they can easily push the first air pipe 51 and the second air pipe 52 when the component 6 moves downward, so that the air outlets of the first air pipe 51 and the second air pipe 52 can rotate and shift to the outside of the lower mold 1, making it easier to blow away the impurities on the upper surface of the lower mold 1 to the outside of the lower mold 1.

[0035] Further, please refer to Figure 3 , 4 As shown in Figure 5, a ring of baffles 9 is provided on the upper surface of the lower die 1, and the baffles 9 surround the stamping groove 10. A collection frame 8 is provided around the lower die 1, which is used to collect impurities falling from the surface of the lower die 1.

[0036] Understandably, the enclosure 9 is used to prevent impurities on the upper surface of the lower die 1 from entering the stamping groove 10, thus providing a shielding and protection function. The collection frame 8 on the outside of the lower die 1 can collect impurities that fall from the surface of the lower die 1. Together with the blowing assembly 5, it can achieve the blowing, cleaning, and collection of impurities, facilitating subsequent centralized processing of impurities and significantly reducing the cleaning workload of workers.

[0037] Preferably, please refer to Figure 6 , 7 As shown, the pushing assembly 6 includes a connecting plate 16, a second connecting rod 17, and a pushing member 18. The connecting plate 16 is connected to the outer wall of the sleeve 3. The second connecting rod 17 is disposed at the bottom of the connecting plate 16. The pushing member 18 is disposed at the bottom end of the second connecting rod 17. The pushing member 18 includes a first pushing plate 181 and a second pushing plate 182 connected to each other. The first pushing plate 181 and the second pushing plate 182 are used to abut and push the first air blowing pipe 51 and the second air blowing pipe 52 respectively when the upper mold 2 approaches the lower mold 1.

[0038] In this preferred embodiment, both the first push plate 181 and the second push plate 182 have a structure that is wider at the top and narrower at the bottom. The first push plate 181 is used to abut against the side wall of the first air blowing pipe 51 with a beveled edge, and the second push plate 182 is used to abut against the side wall of the second air blowing pipe 52 with a beveled edge.

[0039] Understandably, when the upper mold 2 approaches the lower mold 1, the sleeve 3 drives the connecting plate 16 and the pushing component 18 to move downwards. The first pushing plate 181 and the second pushing plate 182 respectively abut against and push the first air blowing pipe 51 and the second air blowing pipe 52. Since the first air blowing pipe 51 and the second air blowing pipe 52 are both made of flexible hose, and the side walls of the first pushing plate 181 and the second pushing plate 182 are both beveled structures, the first air blowing pipe 51 and the second air blowing pipe 52 can be pushed to the outside of the lower mold 1 respectively, so as to change the direction of the air outlet of the first air blowing pipe 51 and the second air blowing pipe 52, and blow the impurities on the surface of the lower mold 1 to the outside. This not only expands the blowing range, but also works with the collection frame 8 to achieve efficient impurity collection.

[0040] Preferably, please refer to Figure 4 As shown, the pressure block assembly includes a first connecting rod 11 and a pressure block 12. The top end of the first connecting rod 11 is connected to the bottom of the upper mold 2, and the pressure block 12 is disposed at the bottom end of the first connecting rod 11. The first connecting rod 11 is used to drive the pressure block 12 to extend into the limiting cavity of the limiting guide 4 to abut against the piston assembly when the upper mold 2 approaches the lower mold 1.

[0041] It is understandable that the diameter of the pressure block 12 is smaller than the diameter of the limiting cavity. The pressure block 12 can slide in the limiting cavity. The pressure block 12 can move up and down with the first connecting rod 11 and the sleeve 3 and the upper mold 2. When it descends, the pressure block 12 abuts against the piston assembly, pushing the piston assembly to compress the air in the limiting cavity, so that the air is blown through the first air blowing pipe 51 and the second air blowing pipe 52 to complete the blowing work on the surface of the lower mold 1.

[0042] Preferably, please refer to Figure 4 As shown, the piston assembly includes a piston 13 and a compression spring 14. The compression spring 14 is disposed in the limiting cavity, and the piston 13 is disposed at the top of the compression spring 14 and is located above the air blowing assembly 5.

[0043] Understandably, the piston 13 can compress the air in the limiting cavity and blow it through the air blowing assembly 5 when it descends. The bottom of the piston 13 is supported by the compression spring 14. When the pressure block 12 moves upward, the compression spring 14 can push the piston 13 upward, and then replenish the limiting cavity with air through the air inlet pipe 7. This cycle repeats, so that the surface of the lower die 1 can be cleaned while the stamping work is being carried out, which greatly reduces the amount of manual cleaning work for workers.

[0044] Optionally, a guide mounting post 19 is provided at the bottom of the limiting cavity, and the bottom end of the compression spring 14 is sleeved on the guide mounting post 19.

[0045] Preferably, please refer to Figure 4 As shown, a limiting block 15 is provided on the inner wall of the limiting cavity, and the limiting block 15 is located above the air blowing assembly 5.

[0046] Understandably, the limiting block 15 can limit the stroke of the piston 13 and also limit the downward stroke of the pushing component 6, so as to prevent the pushing component 6 from impacting the surface of the lower mold 1 and thus protect the pushing component 6.

[0047] It should be noted that the first end of the limiting block 15 is connected to the inner wall of the limiting guide 4, and the second end of the limiting block 15 has an arc surface structure to limit the compression spring 14 and reduce the phenomenon that the compression spring 14 is prone to left and right displacement.

[0048] It should be noted that, in this document, the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0049] This document uses specific examples to illustrate the principles and implementation methods of this application. The examples are merely for the purpose of helping to understand the methods and core ideas of this application. The above descriptions are only preferred embodiments of this application. It should be noted that due to the limitations of written expression, and the existence of an infinite number of specific structures, those skilled in the art can make various improvements, modifications, or variations without departing from the principles of this application, and can also combine the above technical features in an appropriate manner.
