[0025] To make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the specific technical solutions of the present application will be further described in detail below in conjunction with the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application but are not intended to limit the scope of the present application.

[0026] In the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of this application, unless otherwise specified, "multiple" means two or more.

[0027] In addition, in the embodiments of the present application, directional terms such as "up", "down", "left" and "right" are defined relative to the orientation of the components in the drawings. It should be understood that these directional terms are relative concepts. They are used for relative description and clarification, and they may change accordingly according to changes in the orientation of the components in the drawings.

[0028] In the embodiments of the present application, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integrated connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0029] In the embodiments of the present application, the terms "comprises," "comprising," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not preclude the presence of other identical elements in the process, method, article, or apparatus comprising the element.

[0030] In the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of this application should not be interpreted as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0031] The embodiment of the present application provides a car. It should be noted that the car in this application can refer to a large car, a small car, a special-purpose car, etc. For example, according to the model, the car in this application can be a sedan model, an off-road model, a multi-purpose vehicle (MPV) model or other models. For cars, with the development of new energy vehicles, the range extender is concentrated in the electric car. The range extender is a kind of internal combustion engine. The range extender is the main power device that provides driving electricity for the range-extended electric car. The range extender uses gasoline and air to mix, releases huge energy during the combustion process, and converts this energy into electricity for the movement of new energy vehicles; and integrates the power battery into the fuel vehicle to save energy and increase the cruising range of the car. Therefore, it is necessary to process the charging port and the refueling port on the car at the same time.

[0032] The fuel filler port is different from the conventional punching form. It needs to be shaped first, that is, a step-shaped groove is punched on the side outer panel of the car, and then punched. The fuel filler port must be punched sideways.

[0033] On this basis, refer to Figures 1-4 An embodiment of the present application provides a stamping die 10, comprising an upper die 1 and a lower die 2, and a side panel is arranged between the upper die 1 and the lower die 2, and the stamping die 10 processes a fuel filler port on the side panel.

[0034] The upper die 1 is equipped with a movable block 11. As the upper die 1 moves toward the lower die 2, it simultaneously drives the movable block 11 downward. The movable block 11 is equipped with a punch, which is used to machine the fuel filler port on the side panel. The lower die 2 is equipped with a drive mechanism 21 and a drive block 22. The drive mechanism 21 is adapted to drive the drive block 22 toward the movable block 11. When the drive block 22 and the movable block 11 abut, the punch acts on the side panel to machine the fuel filler port.

[0035] The movable block 11 is set on the upper mold 1. The upper mold 1 is relatively stable when it is active, which can achieve the stability of the punch in processing the fuel filler port, so as to reduce the probability of collapse when processing the fuel filler port, and thus improve the yield rate of the processed fuel filler port; the driving mechanism 21 is set on the lower mold 2, and the driving mechanism 21 can be observed, which is convenient for the installation of the driving mechanism 21, and also convenient for the repair or maintenance of the driving mechanism 21.

[0036] A stamping device for a charging port is also provided in the stamping die 10. The stamping die 10 can simultaneously process the fuel filler port and the charging port on the side outer panel. However, some cars only need to process the charging port and do not need to punch out the fuel filler port on the side outer panel. At this time, the driving mechanism 21 does not work and the driving block 22 remains stationary, that is, the driving block 22 does not abut against the movable block 11 and the punch does not act on the side outer panel.

[0037] The stamping die 10 provided in the embodiment of the present application is provided with a movable block 11 on the upper die 1, and the movable block 11 is provided with a punch. The lower die 2 is provided with a driving mechanism 21 and a driving block 22. The driving mechanism 21 drives the driving block 22 to move toward the movable block 11 to process the fuel filler port on the side outer panel. The upper die 1 is relatively stable when it is active, and the stability of the punch in processing the fuel filler port can be achieved, so as to reduce the probability of collapse when processing the fuel filler port, thereby improving the yield rate of the processed fuel filler port; at the same time, the driving mechanism 21 can be observed, which is convenient for the installation of the driving mechanism 21 and also convenient for the repair or maintenance of the driving mechanism 21.

[0038] Reference Figures 1-4 In some embodiments of the present application, the stamping die 10 further includes a presser 3, which is used to secure the side panel to prevent it from slipping when the punch is punching the side panel. The presser 3 can adjust the pressure based on the thickness and hardness of the side panel to prevent deformation or slippage.

[0039] The presser 3 can also be a pressure ring, a pressure plate or a clamping device. The presser 3 is a device that keeps the material stable during the stamping or forming process of the stamping die 10. During the stamping or forming process, the presser 3 can ensure that the side panel fits tightly between the upper die 1 and the lower die 2, preventing the side panel from moving or deforming, thereby ensuring the consistency and accuracy of the fuel filler port processed on the side panel. On the other hand, the quality of the fuel filler port processed on the side panel can be improved: the stress concentration during the fuel filler port forming process can be reduced, thereby improving the quality and durability of the fuel filler port processed on the side panel. In addition, the presser can also play a certain safety role, by fixing the side panel to prevent the operator from directly contacting high-speed moving mechanical parts.

[0040] Reference Figures 1-4 In some embodiments of the present application, the driving block 22 has a first guide sliding surface 111 disposed toward the movable block 11, and the movable block 11 has a second guide sliding surface 221. The second guide sliding surface 221 is adapted to the first guide sliding surface 111, and the first guide sliding surface 111 is adapted to abut against the second guide sliding surface 221. The first guide sliding surface 111 can be disposed on a side of the movable block 11 facing the driving block 22, and the first guide sliding surface 111 is disposed on a side of the driving block 22 facing the movable block 11.

[0041] When the first guide surface 111 and the second guide surface 221 abut, the punch can act on the side panel to form a fuel filler port. The first and second guide surfaces 111, 221 contact and guide each other during operation, ensuring that the movable block 11 accurately follows the predetermined path during the stamping process, thereby improving machining accuracy and stability. However, when the first and second guide surfaces 111, 221 are separated, the punch cannot act on the side panel, preventing the fuel filler port from being formed.

[0042] Reference Figures 1-4 In some embodiments of the present application, the first guide surface 111 and the second guide surface 221 are arranged in parallel, which can ensure that the first guide surface 111 and the second guide surface 221 can completely abut each other. In addition, the parallel arrangement of the first guide surface 111 and the second guide surface 221 can provide a stable guiding effect for the driving block 22 and the movable block 11, making the movement smoother and reducing the wear caused by friction or uneven force. When the movable block 11 is driven by the driving force of the driving block 22, it can move smoothly along the predetermined direction, avoiding the problem of jamming or wear caused by the angular deviation between the first guide surface 111 and the second guide surface 221, thereby ensuring the stability and reliability of the stamping die 10 during operation.

[0043] Reference Figures 1-4 In some embodiments of the present application, both the first guide surface 111 and the second guide surface 221 are inclined. The first guide surface 111 and the second guide surface 221 can form a certain angle with the horizontal plane, which can facilitate lateral machining of the fuel filler port. The first guide surface 111 and the second guide surface 221 are both inclined, which can help guide the movable block 11 and the driving block 22 to move along a predetermined path.

[0044] For example, the upper mold 1 drives the movable block 11 to move downward, the driving mechanism 21 drives the driving block 22 to move horizontally, the first guide sliding surface 111 is tilted along the up and down direction, and the second guide sliding surface 221 is tilted along the up and down direction.

[0045] The first guide surface 111 and the second guide surface 221 are both inclined, meaning they are not arranged vertically or horizontally, but rather have a certain inclination angle relative to the reference plane of the stamping die 10. The inclined angle of the first guide surface 111 and the second guide surface 221 can reduce friction between the movable block 11 and the driving block 22, making the movable block 11 easier to move. Furthermore, the inclined arrangement of the first guide surface 111 and the second guide surface 221 can better control the motion trajectory of the movable block 11, making the motion smoother and more controllable.

[0046] Reference Figures 1-4In some embodiments of the present application, the drive mechanism 21 includes a drive cylinder 211, which includes a cylinder body 2111 and a telescopic rod 2112. The telescopic rod 2112 is capable of telescopically driving the drive block 22. When the telescopic rod 2112 extends from the cylinder body 2111, it can drive the drive block 22 in a direction away from the cylinder body 2111; when the telescopic rod 2112 retracts into the cylinder body 2111, it can drive the drive block 22 in a direction toward the cylinder body 2111. Using the drive cylinder 211 to drive the drive block 22 can improve the stability of the drive block 22.

[0047] When compressed air enters through one end of cylinder 2111, the piston inside cylinder 2111 is acted upon by the air pressure, pushing telescopic rod 2112 outward. When compressed air enters from the other end of cylinder 2111, the piston moves in the opposite direction, causing telescopic rod 2112 to retract. By controlling the direction of the airflow, the telescopic rod 2112 can be extended and retracted, thereby driving the drive block 22 to move.

[0048] Reference Figures 1-4 In some embodiments of the present application, the lower mold 2 is also provided with a driving guide plate, which is used to guide the movement direction of the driving block 22. When the driving mechanism 21 drives the driving block 22 to move, the driving block 22 can move along the direction specified by the driving guide plate to prevent the driving block 22 from slipping.

[0049] When the driving block 22 moves, the driving guide plate can ensure that the driving block 22 moves along a predetermined direction, prevent the driving block 22 from deflecting or getting stuck, and provide necessary support when the driving block 22 moves, thereby reducing unstable factors during movement.

[0050] Reference Figures 1-4 In some embodiments of the present application, two drive guides are provided, and the two drive guides are spaced apart along a first direction of the drive block 22, where the first direction is perpendicular to the direction of movement of the drive block 22. The two drive guides can better guide the drive block 22 to move along a specified direction, ensuring its stability during movement; and the two drive guides can provide guidance from different positions, making the movement path of the drive block 22 more precise and controllable. Providing drive guides on both sides of the drive block can make the load of the drive block more evenly distributed during movement, reducing the possibility of single-point wear. The two drive guides can effectively reduce the shaking of the drive block 22 during movement, thereby improving the service life and stamping quality of the stamping die 10.

[0051] Reference Figures 1-4In some embodiments of the present application, the upper mold 1 is further provided with a connecting guide plate, and the movable block 11 is movably provided on the upper mold 1, and the movable block 11 can move relative to the upper mold 1. The connecting guide plate is used to guide the movement direction of the movable block 11. When the movable block 11 moves, the movable block 11 can move along the direction specified by the connecting guide plate, thereby preventing the movable block 11 from slipping.

[0052] The connecting guide plate is designed to guide the movement of the movable block 11 during its working stroke. This ensures smoother and more accurate movement of the movable block 11. The presence of the connecting guide plate prevents the movable block 11 from deviating from its intended path due to external interference or its own weight while performing its function.

[0053] Reference Figures 1-4 In some embodiments of the present application, two connecting guide plates are provided, and the two connecting guide plates are spaced apart along the second direction of the movable block 11. The second direction is a direction perpendicular to the movable direction of the movable block 11. The two connecting guide plates can better guide the movable block 11 to move along the specified direction.

[0054] The two connecting guides can better support and guide the movable block 11, ensuring its stability during movement; the two guides can provide better balance and support, preventing the movable block 11 from deflecting or shaking during movement. The two connecting guides provide guidance from different positions, making the movement path of the movable block 11 more precise and controllable. Through the collaboration of the two connecting guides, it can be ensured that the movable block 11 moves along the predetermined direction, thereby improving the stamping accuracy. The two connecting guides can make the load borne by the movable block 11 during movement more evenly distributed, reduce the stress borne by a single connecting guide, and thus extend the service life of the connecting guide and the entire stamping die 11.

[0055] Refer to the following Figures 1-4 The stamping die 10 according to the embodiment of the present application is described.

[0056] The stamping die 10 includes an upper die 1 and a lower die 2. The upper die 1 is provided with a movable block 11, which is equipped with a punch. The lower die 2 is provided with a drive mechanism 21 and a drive block 22. The drive mechanism 21 drives the drive block 22 toward the movable block 11. The stamping die 10 also includes a punch 3, which is used to fix the side panel. The punch is used to process the fuel filler port on the side panel.

[0057] The driving block 22 has a first guide surface 111 facing the movable block 11. The movable block 11 has a second guide surface 221 that matches the first guide surface 111. The first guide surface 111 is adapted to abut against the second guide surface 221. The first and second guide surfaces 111, 221 are arranged parallel and at an angle. When the first and second guide surfaces 111, 221 abut, a punch can be applied to the side panel to form a fuel filler port.

[0058] The drive mechanism 21 includes a drive cylinder 211, which comprises a cylinder body 2111 and a telescopic rod 2112. The telescopic rod 2112 is configured to telescopically drive the movement of the drive block 22. The lower mold 2 is also provided with two drive guides, spaced apart along a first direction of the drive block 22, to guide the movement of the drive block 22.
