Description

Technical Field

[0001] This application relates to the field of electric vehicle battery swapping technology, and more specifically, to a heavy-duty truck connecting plate type manual battery swapping locking mechanism. Background Technology

[0002] Heavy-duty trucks are a traditional, informal term for heavy-duty freight trucks and semi-trailer tractors, encompassing various specialized vehicles used on highways (water trucks, fire trucks, tanker trucks, etc.), dump trucks, freight trucks, and some less common off-road vehicles. New energy heavy-duty trucks are heavy-duty trucks that use new energy sources such as electricity, hydrogen, and natural gas as their power source. They are environmentally friendly, energy-saving, and highly efficient, and are mainly used in logistics transportation, engineering construction, and mining. Battery-powered electric drive is the primary form of new energy heavy-duty trucks.

[0003] The battery swapping model for electric vehicles refers to the centralized storage, charging, and distribution of a large number of batteries through centralized charging stations, and the provision of battery swapping services for electric vehicles within these stations. This model integrates battery charging, logistics allocation, and battery swapping services. Due to the rapid development of battery swapping-based new energy heavy-duty trucks, the reliability requirements for battery swapping in heavy-duty trucks have been increasing in recent years.

[0004] Connecting plate devices are used to assemble disparate components or parts into a unified structure through bolting, welding, or riveting. They are widely used in building steel structures, machinery, and transportation vehicles. Battery-swapping heavy-duty trucks are equipped with connecting plate-type battery-swapping bases. These bases have electrical connection interfaces, and the battery frame assembly is detachably mounted on the base and mates with the electrical connection interface. The battery-swapping base also features a locking mechanism to secure the battery frame assembly to the base.

[0005] Currently, most battery swapping systems on the market use electric or hydraulic locking mechanisms, which suffer from a certain failure rate during operation, resulting in high costs and poor economic efficiency. Vehicles are also prone to battery swapping unlocking failures at battery swapping stations. Therefore, designing a manually unlocking battery swapping base to address battery swapping failures for heavy-duty trucks at swapping stations and to overcome the cost difference between battery swapping and charging is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] In view of this, the purpose of this application is to provide a manual battery swapping locking mechanism for heavy-duty truck connecting plates, which effectively solves the problems of high battery swapping costs and easy failures in the prior art.

[0007] To achieve the above objectives, this application provides the following technical solution:

[0008] A heavy-duty truck connecting plate type manual battery swapping locking mechanism includes a battery swapping base frame, a locking member movably disposed on the battery swapping base frame for cooperating with a battery frame assembly, and a transmission mechanism. The transmission mechanism includes a force-applying member and a transmission component. The force-applying member is movably connected to the edge of the battery swapping base frame and is for applying force manually. The transmission component is located between the locking member and the force-applying member and is used to transmit the force or torque generated by the force-applying member to the locking member.

[0009] Preferably, the locking component includes a mounting rod and a locking rod. The mounting rod is rotatably mounted on the battery swapping base frame, and the locking rod is fixedly connected to one end of the mounting rod. The length direction of the locking rod is perpendicular to the rotation axis of the mounting rod.

[0010] Preferably, the transmission assembly includes a control slide rod, which is slidably mounted on the battery swapping base frame. A force-bearing swing rod is fixedly connected to the mounting column. The control slide rod applies a thrust to the force-bearing swing rod. The sliding direction of the control slide rod is perpendicular to the rotation axis of the mounting column.

[0011] By adopting the above technical solution, since the direction of movement of the control slide rod is perpendicular to the rotation axis of the mounting column, the force generated when the control slide rod moves can be converted into torque acting on the mounting column, driving the mounting column to rotate and realizing the function of the locking component.

[0012] Preferably, a transmission sliding pin is connected to the control slide rod, and a transmission waist-shaped hole is opened on the force-bearing swing rod. The length direction of the transmission waist-shaped hole is the radial direction of the rotation trajectory of the mounting column rod, and the transmission sliding pin is located inside the transmission waist-shaped hole and contacts the hole wall of the transmission waist-shaped hole.

[0013] Preferably, the length direction of the force-bearing swing rod is consistent with the length direction of the transmission waist-shaped hole, and the maximum swing angle of the force-bearing swing rod is 90°.

[0014] By adopting the above technical solution, the cooperation between the transmission waist-shaped hole and the transmission sliding pin ensures that the control slide rod can always maintain a mechanical transmission relationship with the force-bearing swing rod. At the same time, the length of the transmission waist-shaped hole limits the stroke angle range between the two. The rotation angles of the force-bearing swing rod and the locking rod change synchronously, which facilitates the operator's control of the rotation angle of the locking component.

[0015] Preferably, multiple locking members and multiple control slide rods are provided. The transmission assembly also includes a linkage frame, which is slidably connected to the battery swapping base frame. The linkage frame is fixedly connected to all the control slide rods, and the force-applying member is fixedly connected to the edge of the linkage frame.

[0016] Preferably, the battery swapping base is provided with a thick guide post, the thick guide post and the locking member are located on the same side of the battery swapping base, and the end of the thick guide post away from the battery swapping base is formed with a sharp corner.

[0017] Preferably, a precision positioning post is also provided on the battery swapping base frame on the same side as the coarse guide post. The length direction of the precision positioning post is parallel to the length direction of the mounting post, and the end of the precision positioning post away from the battery swapping base frame is formed with a conical tip.

[0018] Preferably, the battery swapping base has an electrical connection interface in the middle for docking with the battery frame assembly, the coarse guide post is located at the edge of the battery swapping base, and the fine positioning post is closer to the electrical connection interface than the coarse guide post.

[0019] By adopting the above technical solution, when the battery frame assembly and the battery swapping base are installed together, the coarse guide post makes the battery frame assembly and the battery swapping base roughly aligned, and then the fine positioning post makes the battery connector and electrical connection interface more precisely aligned, thus improving the ease of installation and operation of the battery frame assembly.

[0020] Preferably, a buffer pad is fixedly connected to the battery swapping base and located next to the electrical connection interface, and the side of the buffer pad facing away from the battery swapping base is in contact with the battery frame assembly.

[0021] The heavy-duty truck connecting plate type manual battery swapping locking mechanism provided in this application allows the operator to directly apply force to the force-applying component during the battery swapping process. The tendency of the force-applying component to move relative to the battery swapping base is converted into a force, which is then transmitted through the transmission component to drive the locking component to move. This changes the state of the locking component relative to the battery swapping base and the battery frame assembly, allowing the locking component to release the battery frame assembly, which can then be easily removed. Reinstalling the battery frame assembly is achieved by reversing the operation. Manual force application does not rely on other forms of power sources or equipment such as electric or hydraulic systems, thus effectively reducing equipment costs and the failure rate during the battery swapping process.

Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

This application discloses a heavy-duty truck connecting plate type manual battery swapping locking mechanism.

[0029] The core of this application is to provide a manual battery swapping locking mechanism for heavy-duty truck connecting plates.

[0030] refer to Figures 1-2 .

[0031] The heavy-duty truck connecting plate type manual battery swapping locking mechanism provided in this application includes a battery swapping base frame 1 and a transmission mechanism 3. The battery swapping base frame 1 is a rectangular steel structure frame, with an electrical connection interface 12 fixedly installed in its middle for docking with the battery frame assembly. A locking member 2 is movably installed on the battery swapping base frame 1, which is used to cooperate with the battery frame assembly. The movement of the locking member 2 is used to lock or unlock the battery frame assembly. The transmission mechanism 3 includes a force-applying member 31 and a transmission component 32. The force-applying member 31 is located at the edge of the battery swapping base frame 1 and is for manual force application. The transmission component 32 is used to transmit the force or torque generated by the force-applying member 31 to the locking member 2, so that the locking member 2 can move to perform its own function.

[0032] like Figure 1 As shown, the locking component 2 is T-shaped and includes a mounting rod 21 and a locking rod 22. The mounting rod 21 is rotatably mounted on the battery swapping base frame 1, with its own axis and rotation axis as the axis of rotation. The locking rod 22 is fixedly connected to the end of the mounting rod 21 facing the battery frame assembly, and the length direction of the locking rod 22 is perpendicular to the rotation axis of the mounting rod 21. The battery frame assembly has a straight locking hole (not shown in the figure) for the locking component 2 to be inserted. The shape of the locking hole corresponds to the shape of the locking rod 22. When the locking rod 22 enters the locking hole, the mounting rod 21 rotates at a certain angle, and the locking rod 22 cannot be withdrawn from the locking hole, thereby achieving a locking connection of the battery frame assembly.

[0033] like Figure 2 As shown, a force-bearing swing rod 23 is fixedly connected to the other end of the mounting column 21. The length direction of the force-bearing swing rod 23 is radial to that of the mounting column 21. A transmission waist-shaped hole 231 is provided on the force-bearing swing rod 23, and the length direction of the transmission waist-shaped hole 231 is consistent with the length direction of the force-bearing swing rod 23. The transmission assembly 32 includes a control slide rod 321, which is slidably mounted on the battery swapping base frame 1. The sliding direction is parallel to the length direction of the battery swapping base frame 1 and perpendicular to the rotation axis of the mounting column 21. A transmission pin 322 is fixedly connected to the control slide rod 321. The transmission pin 322 is located inside the transmission waist-shaped hole 231 and contacts the hole wall of the transmission waist-shaped hole 231. When the control slide rod 321 moves, the transmission pin 322 will generate a thrust on the hole wall of the transmission waist-shaped hole 231, thereby causing the force-bearing swing rod 23 to rotate. The force-bearing swing rod 23 then drives the locking member 2 to rotate. The length of the transmission waist-shaped hole 231 limits the travel of the control slide rod 321 and the transmission pin 322, and also limits the maximum rotation angle of the force-bearing swing rod 23 and the mounting column 21. In this embodiment, the maximum swing angle of the force-bearing swing rod 23 is 90°.

[0034] like Figure 1 and 2 As shown, there are four locking components 2 evenly distributed around the electrical connection interface 12, so there are also four force-bearing swing rods 23 and four transmission sliding pins 322. There are two control sliding rods 321, with each control sliding rod 321 connecting two transmission sliding pins 322. The transmission assembly 32 also includes a linkage frame 323, which is slidably connected to the battery swapping base frame 1. The linkage frame 323 is a rectangular steel frame, which is welded and fixed to all control sliding rods 321. The number and arrangement of the locking components 2 are adjusted according to the specific needs of the battery frame assembly's fastening requirements.

[0035] like Figure 2As shown, the force-applying component 31 is a grip handle, which is fixedly connected to one edge of the linkage frame 323. To improve the convenience of manual operation, the grip handle is located at the edge of the battery swapping base frame 1, and when the locking component 2 locks the battery frame assembly, the edge of the grip handle is flush with the edge of the battery swapping base frame 1. Manual operation applies a pulling or pushing force to the force-applying component 31, which causes the force-receiving swing arm 23 to rotate through the transmission component 32. The force-receiving swing arm 23 then drives the locking component 2 to rotate 90°, thereby easily realizing the manual locking or unlocking operation of the battery frame assembly. Even when the external power source equipment cannot work, the battery frame assembly can still be unlocked or locked, ultimately realizing the battery swapping operation.

[0036] The manual battery swapping locking mechanism for heavy-duty truck connecting plates provided in this application will be described in more detail below with reference to the accompanying drawings and specific embodiments.

[0037] In one specific implementation, reference is made to... Figure 2 .

[0038] Specifically, during battery swapping, the relative movement direction of the battery frame assembly and the battery swapping base 1 is parallel to the length direction of the mounting post 21. Two coarse guide posts 4 and four fine positioning posts 5 are fixedly installed on the battery swapping base 1 on the same side as the locking member 2, used to guide and correct the alignment of the battery frame assembly as it approaches the battery swapping base 1. The end of the coarse guide post 4 away from the battery swapping base 1 has a pointed corner 41, and the end of the fine positioning post 5 away from the battery swapping base 1 has a conical tip 51. The conical tip 51 and the fine positioning post 5 are coaxial; the total length of the coarse guide post 4 is greater than the total length of the fine positioning post 5. The coarse guide posts 4 are located at the edge of the battery swapping base 1, with two coarse guide posts 4 located at a pair of diagonal positions on the battery swapping base 1. The fine positioning posts 5 are closer to the electrical connection interface 12 than the coarse guide posts 4, and the four fine positioning posts 5 are arranged in an array around the electrical connection interface 12.

[0039] Based on any of the above embodiments, refer to Figure 2 .

[0040] Specifically, a rubber buffer pad 11 is fixedly connected to the battery swapping base 1 and next to the electrical connection interface 12. There are two buffer pads 11, which are located on opposite sides of the electrical connection interface 12. When the battery frame assembly is locked onto the battery swapping base 1, the side of the buffer pad 1 that is away from the battery swapping base 1 contacts the battery frame assembly. It is used to reduce the impact force generated when the two come into contact, thereby reducing structural damage.

[0041] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are merely for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make various improvements and modifications to this application without departing from its principles, and these improvements and modifications also fall within the protection scope of this application.
