[0002] Product electrification has become the mainstream direction of industry development in the field of engineering machinery technology. For example, loaders, as commonly used engineering machinery in railways, mines, ports and other fields, have been developed to varying degrees. However, since the current battery technology still has the risk of spontaneous combustion, in order to ensure that the electric engineering machinery encounters a battery failure during use, the battery needs to be discarded in time to ensure the safety of the engineering machinery body. When the electric engineering machinery is abandoning power, it is necessary to quickly unlock and separate the interlock between the battery pack and the engineering machinery, so that the battery can be safely, reliably and quickly separated from the engineering machinery body, thereby preventing the spread of battery accidents and avoiding greater economic losses caused by battery failures. Therefore, a stable and reliable positioning structure between the battery pack and the engineering machinery of the engineering machinery is needed to ensure the stable interlocking of the battery pack and the engineering machinery during normal operation of the engineering machinery, and when the battery pack has a spontaneous combustion failure, a positioning structure that can quickly separate the battery pack from the engineering machinery body is needed.

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings.

[0026] like Figures 1 to 7 As shown, the utility model provides a positioning structure for automatically abandoning power in case of distress, including a bottom support frame 1, an upper support frame 2, and a battery pack frame 3, wherein the bottom support frame 1 is used to be fixedly connected to the engineering machinery so that the positioning structure can be reliably connected to the engineering machinery to realize the function of the positioning structure, and the battery pack frame 3 is used to install battery components such as lithium batteries and related control components that can provide power to the engineering machinery. One side of the upper support frame 2 is rotatably connected to the bottom support frame 1, and specifically, the upper support frame 2 and the bottom support frame 1 can be connected by a hinge. A supporting cylinder 11 is connected to the side of the bottom support frame 1 and the upper support frame 2 away from the mutual rotational connection, and the supporting cylinder 11 is used to support the upper support frame 2 to flip relative to the bottom support frame 1 to separate the upper support frame 2 from the bottom support frame 1. Specifically, the supporting cylinder 11 can be driven by hydraulic pressure or pneumatic pressure, and the upper support frame 2 can be flipped relative to the bottom support frame 1 by the supporting of the supporting cylinder 11, and during the flipping process of the upper support frame 2, as shown in FIG. Figures 1 to 3 As shown, it also drives the battery pack frame 3 to flip over at the same time. When the battery pack is flipped to a certain position, it can rely on the gravity of the battery pack itself to slide off the upper support frame 2, that is, it is separated from the engineering machinery body. The bottom support frame 1 is fixedly connected to a plurality of lower limit posts 12, and the lower end of the battery pack frame 3 is fixedly connected to a first limit member 31 and a second limit member 32. When the upper support frame 2 and the bottom support frame 1 are fitted together, the first limit member 31, the second limit member 32 and the lower limit post 12 are mutually sleeved so that the battery pack frame 3 can be reliably connected to the bottom support frame 1. That is, when the battery pack frame 3 is in a position relative to the bottom support frame 1 as shown in FIG. Figure 1 In the position state shown, the first limit member 31, the second limit member 32 and the lower limit column 12 are in a mutually nested state, thereby limiting the relative movement of the battery pack frame 3 relative to the bottom support frame 1 in the horizontal plane, thereby ensuring that the battery pack frame 3 can be stably and reliably connected to the engineering machinery body during normal operation of the engineering machinery and at the same time provide a stable and reliable power supply for the engineering machinery.

[0027] like Figure 4 , Figure 5 As shown, the transverse cross section of the first stopper 31 is circular, and the first stopper 31 is connected to the side of the battery pack frame 3 away from the rotational connection between the upper support frame 2 and the bottom support frame 1. The transverse cross section of the second stopper 32 is semicircular opening, and the second stopper 32 is connected to the side of the battery pack frame 3 close to the rotational connection between the upper support frame 2 and the bottom support frame 1, and the semicircular opening of the second stopper 32 faces the first stopper 31. Figures 4 to 5 As shown, the battery pack frame 3 limiting structure composed of the first limiting member 31 and the second limiting member 32 can form a stable limiting structure at the bottom of the battery pack frame 3, that is, through the cooperation between the first limiting member and the second limiting member 32, the battery pack frame 3 can be firmly connected to the bottom support frame 1 to ensure the reliability of the positioning structure when the engineering machinery is in normal operation. When the battery of the engineering machinery fails, such as spontaneous combustion, the battery pack frame 3 needs to be abandoned from the engineering machinery body in time. Figures 1 to 3 The figure shows the entire position change process of the battery pack frame 3 being abandoned from the bottom support frame 1. Figures 1 to 3 It can be seen from the position change of the battery pack frame 3 that since the second limit member 32 is close to one end of the hinge between the bottom support frame 1 and the upper support frame 2, the battery pack frame 3 is in the process of flipping relative to the bottom support frame 1. The radius of the flipping arc of the second limit member 32 is relatively small. Therefore, in order to avoid the second limit member 32 and the lower limit column 12 being stuck to each other during the flipping process of the battery pack frame 3, thereby affecting the flipping and power-discarding operation of the battery pack frame 3, the second limit member 32 is set to a semicircular structure, which can avoid the battery pack frame 3 from rubbing and scratching against the lower limit column 12 during the flipping and power-discarding process, thereby ensuring the reliable power-discarding operation of the battery pack frame 3.

[0028] Preferably, Figures 4 to 6 As shown, the utility model provides a positioning structure for automatically abandoning power in case of distress. In order to ensure that the first limiting member 31 and the second limiting member 32 can reliably connect the upper support frame 2 with the bottom support frame 1 when the engineering machinery is in normal operation, the first limiting member 31 includes at least two, and the two ends of the battery pack frame 3 away from the side where the upper support frame 2 is rotatably connected to the bottom support frame 1 are fixedly connected with the first limiting member 31. Correspondingly, the second limiting member 32 includes at least two, and the two ends of the battery pack frame 3 close to the side where the upper support frame 2 is rotatably connected to the bottom support frame 1 are fixedly connected with the second limiting member 32. That is, the first limiting member 31 and the second limiting member 32 are arranged in a multi-structured form at the bottom of the battery pack frame 3, and at the same time cooperate with a corresponding number of lower limiting columns 12, which can better ensure the stable connection between the battery pack frame 3 and the bottom support frame 1 during normal operation of the engineering machinery.

[0029] Preferably, in the utility model, a positioning structure for automatically abandoning power in case of distress is provided. To reduce the production and processing cost of the first stopper 31, the first stopper 31 is made of a steel plate cut by laser, and the second stopper 32 is made of a steel plate cut by laser. Figure 5As shown, the first limiter 31 and the second limiter 32 are both of a flat plate structure, and this structure can be directly made of a thicker steel plate by laser cutting, which greatly reduces the processing difficulty of the first limiter 31 and the second limiter 32, thereby better saving costs for the positioning structure of this practical type. Accordingly, in order to reduce the overall production and processing cost of the positioning structure to ensure that the positioning structure can be better promoted and used, the bottom support frame 1 is welded with square steel pipes, and the upper support frame 2 is welded with square steel pipes. That is, by using relatively lower-cost square steel pipes, the structural strength of the upper support frame 2 can be guaranteed while also better controlling the production and manufacturing cost of the upper support frame 2.

[0030] Preferably, the utility model provides a positioning structure for automatically abandoning power in case of distress, so as to ensure that the lower limit column 12 can stably engage with the first limit member 31 and the second limit member 32 to ensure a reliable connection between the upper support frame 2 and the bottom support frame 1 when the engineering machinery is operating normally. Figure 7 As shown, the end of the lower limit column 12 close to the bottom support frame 1 is a cylindrical structure, and the end of the lower limit column 12 away from the bottom support frame 1 is a conical structure. That is, when the battery pack frame 3 is connected to the bottom support frame 1, the conical structure can provide a better guiding effect for the first limit structure and the second limit structure, thereby facilitating the connection of the battery pack frame 3 and the bottom support frame 1, which is also the engineering machinery body, into one body. Figure 1 As shown, when the battery pack frame 3 approaches the bottom support frame 1, the first limiter 31 and the second limiter 32 are mutually engaged with the bottom cylinder of the lower limiter column 12. At this time, the first limiter 31, the second limiter 32 and the lower limiter column 12 form a stable engagement structure, thereby preventing the battery pack frame 3 from moving along the horizontal plane relative to the bottom support frame 1 during the normal operation of the engineering machinery. In order to make the first limiter 31, the second limiter 32 and the lower limiter column 12 better cooperate to play the role of limiting the movement of the battery pack frame 3 relative to the bottom support frame 1 on the horizontal plane, the transverse cross-section of the second limiter 32 is semicircular in diameter and directly matches the cylindrical diameter of one end of the lower limiter column 12 approaching the bottom support frame 1, and the transverse cross-section of the first limiter 31 is circular in diameter and directly matches the cylindrical diameter of one end of the lower limiter column 12 approaching the bottom support frame 1, so that the connection between the upper support frame 2 and the bottom support frame 1 is stable and reliable.
