Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] The core of this utility model is to provide a manually unlockable battery swapping base. By pulling the locking rod, the locking head can be moved between the locked and unlocked positions, realizing the mechanical locking and unlocking of the battery frame assembly. It has a simple structure, is easy to operate and has a low cost, low battery swapping failure rate and high battery swapping efficiency.

[0026] The present invention provides a manual unlocking battery swapping base, including a battery swapping base 10. The battery swapping base 10 is provided with a guide component 1 for guiding the battery frame assembly, a positioning component 2 for positioning the battery frame assembly, a locking component 3 for locking the battery frame assembly, and a battery swapping interface 4 for electrically connecting to the battery frame assembly.

[0027] The locking assembly 3 includes a locking mounting base 31, a locking head 32, and a locking lever 33. The locking mounting base 31 is located on the battery swapping base 10, the locking head 32 is located in the mounting hole of the locking mounting base 31, and the bottom of the locking head is provided with a locking lever 33 so that the locking lever 33 can drive the locking head 32 to move between the locked position and the unlocked position.

[0028] The battery swapping base 10 is used to connect to the battery frame assembly in order to support and charge the battery frame assembly. The battery swapping base 10 is usually set as a frame structure. In order to reduce the collision between the battery swapping base 10 and the battery frame assembly, the outer edge of the battery swapping base 10 is provided with a buffer pad 5. The buffer pad 5 can be glued to the surface of the battery swapping base 10, or it can be connected to the battery swapping base 10 by fastening bolts and other connecting parts.

[0029] To effectively support the battery frame assembly, the battery swapping base 10 can be provided, including a base frame and a base longitudinal beam located within the base frame. The base longitudinal beam is arranged along the length of the battery swapping base 10. The base frame and the base longitudinal beam are usually made of stainless steel, which has high strength, strong load-bearing capacity, and is easy to process.

[0030] The top of the battery swapping base 10 is provided with a guide component 1, a positioning component 2, a locking component 3, and a battery swapping interface 4. The guide component 1 is used to provide coarse guidance for the battery frame assembly, and the positioning component 2 is used to provide precise positioning for the battery frame assembly, so as to guide the battery swapping interface of the battery frame assembly to be accurately aligned and connected with the battery swapping interface 4.

[0031] The specific quantity, structure, size, and distribution of the guiding component 1 and the positioning component 2 are determined based on the structure and size of the battery frame assembly to be swapped in actual production. For example, in a specific embodiment, such as... Figure 1 As shown, a pair of guide components 1 are provided diagonally on the battery swapping base 10. The guide component 1 includes a guide mounting plate and a guide plate. The guide plate can cooperate with the guide grooves on both sides of the battery frame assembly. The sliding pair of the guide plate and the guide groove limits the movement direction of the battery frame assembly, so as to limit the battery frame assembly through coarse guidance and facilitate the precise alignment of the battery frame assembly and the positioning component 2.

[0032] The positioning component 2 includes a positioning post, which can be engaged with the positioning point at the bottom of the battery frame assembly. When the positioning post and the positioning point are engaged, the battery swapping interface 4 of the battery swapping base 10 and the battery swapping interface of the battery frame assembly are connected to each other to realize the electrical connection between the battery swapping base 10 and the battery frame assembly and to charge the battery frame assembly.

[0033] Preferably, in order to simplify the layout of the battery swapping base 10, the two guide components 1 are symmetrically arranged about the center of the battery swapping interface 4. The guide components 1 are diagonally distributed on the battery swapping base 10. Compared with setting guide components 1 at all four corners of the battery swapping base 10, the battery swapping base 10 has a simple structure and low manufacturing cost.

[0034] Meanwhile, in order to shorten the alignment stroke of the battery swapping base 10 and the battery frame assembly, it is preferable to set the guide component 1 at both ends in the width direction of the battery swapping base 10. Compared with the guide component 1 being set at both ends in the length direction of the battery swapping base 10, the alignment adjustment stroke of the battery frame assembly is shorter, which is beneficial to improving alignment efficiency and battery swapping efficiency.

[0035] The locking component 3 is used to lock the battery frame assembly in conjunction with the locking hole at the bottom of the battery frame assembly, ensuring that the battery frame assembly will not move relative to the battery swapping base 10 during the charging process. This ensures the stability and reliability of the connection between the battery swapping interface of the battery frame assembly and the battery swapping interface 4 of the battery swapping base 10, thereby ensuring the continuity and safety of the charging process.

[0036] The locking assembly 3 includes a locking mounting base 31 for connecting to the battery swapping base 10. The locking mounting base 31 can be installed on the locking mounting base 31 by a detachable connection method such as bolt connection or pin connection, or it can be connected to the locking mounting base 31 by a non-detachable connection method such as welding connection, or it can be set as an integral structure with the battery swapping base 10.

[0037] The locking mounting base 31 is provided with a locking head 32, which is used to engage with the locking hole at the bottom of the battery frame assembly. Therefore, the structure, shape and size of the locking head 32 are determined according to the structure, shape and size of the locking hole in actual production. The locking head 32 is connected to the locking rod 33 so that the locking rod 33 can drive the locking head 32 to move between the locked position and the unlocked position.

[0038] It should be noted that the above-mentioned movement is not limited to the sliding connection between the locking head 32 and the locking mounting base 31, and the locking head 32 being able to move relative to the locking mounting base 31 in the horizontal plane, but also includes the locking head 32 being rotatably disposed within the locking mounting base 31, and the locking head 32 being able to rotate relative to the locking mounting base 31.

[0039] Please refer to Figure 1 and Figure 2 The locking head 32 is rotatably mounted in the locking mounting base 31 via a bearing, and the locking rod 33 is located below the locking mounting base 31. The locking head 32 and the locking mounting base 31 are rotatably connected. Compared with the sliding connection between the two, the locking mounting base 31 is smaller in size, and the structure of the locking assembly 3 is more compact, which helps to reduce the cost of the battery swapping base 10 and improve economic performance.

[0040] Meanwhile, the locking lever 33 is located below the locking mounting base 31, which avoids collision or interference between the locking lever 33 and the guide assembly 1 or the battery frame assembly during the movement of the locking lever 33, ensuring that the locking lever 33 has sufficient movement space and does not require increasing the size of the battery swapping base 10.

[0041] In this embodiment, the manually unlocked battery swapping base can move the locking head 32 between the locked and unlocked positions by pulling the locking rod 33, thereby realizing the mechanical locking and unlocking of the battery frame assembly. Compared with electric or hydraulic locking components, it has a simple structure, is easy to operate, and has a low cost. It can also avoid the failure problems of complex electric or hydraulic systems, reduce the failure rate of battery swapping unlocking or locking, and thus improve battery swapping efficiency.

[0042] After the locking head 32 engages with the locking hole of the battery frame assembly, the locking lever 33 is fixed relative to the battery swapping base 10. If the operator accidentally touches the locking lever 33 at this time, since the locking lever 33 is used to drive the locking head 32, the force exerted by the locking lever 33 on the locking head 32 will act on the locking hole, which may easily cause damage to the locking hole.

[0043] Preferably, the locking assembly 3 may be equipped with a locking element, which is used to fix the locking rod 33 in the locking position to prevent the operator from accidentally touching the locking rod 33 after the locking head 32 is locked; the locking element may be specifically configured as a positioning pin, a set screw, etc.

[0044] For example, the locking rod 33 can be set to protrude from the outer edge of the battery swapping base 10. The battery swapping base 10 is provided with a fixed rod. Both the locking rod 33 and the fixed rod are provided with positioning pin holes for installing positioning pins.

[0045] When the locking rod 33 moves the locking head 32 to the locking position, the positioning pin passes through the positioning pin hole of the locking rod 33 and the positioning pin hole of the fixing rod in sequence, thereby fixing the locking rod 33 in the locking position and preventing the locking rod 33 from moving due to accidental contact or other external forces.

[0046] Based on the above embodiments, an elastic reset member can be provided between the locking rod 33 and the battery swapping base 10. When the locking head 32 disengages from the locking hole of the battery frame assembly, the elastic reset member drives the locking rod 33 and the locking head 32 to reset from the locked position to the unlocked position.

[0047] When the operator controls the locking rod 33 to move the locking head 32 from the unlocked position to the locked position, the locking rod 33 does work to overcome the resistance of the elastic reset member, and the elastic reset member accumulates elastic potential energy until the locking head 32 engages with the locking hole.

[0048] Therefore, after the locking head 32 disengages from the locking hole, the locking hole no longer has a locking and limiting effect on the locking head 32, and the elastic restoring force of the elastic reset member drives the locking head 32 and the locking rod 33 to reset.

[0049] The specific type of the resilient reset element is related to the movement of the locking head 32 between the locked and unlocked positions.

[0050] Please refer to Figure 1 and Figure 2 When the locking head 32 locks and unlocks by rotating, the elastic locking element may include a torsion spring. The torsion spring is sleeved outside the pin of the locking rod 33. One end of the torsion spring is connected to the locking rod 33, and the other end of the torsion spring is connected to the locking mounting seat 31.

[0051] When the locking head 32 locks and unlocks by linear movement, the elastic locking element includes a spring, one end of which is connected to the locking lever 33, and the spring is connected to the battery swapping base 10; of course, the above spring can be set as a tension spring or a compression spring depending on the actual installation position.

[0052] Based on the above embodiments, considering that the battery frame assembly is provided with multiple locking holes, in order to achieve synchronous movement of the corresponding multiple locking heads 32, the battery swapping base 10 can also be provided with a synchronous pull rod 6. The locking pull rod 33 of each locking component 3 is hinged to the synchronous pull rod 6. When the synchronous pull rod 6 is pushed or pulled, the synchronous pull rod 6 drives the locking head 32 to move synchronously through the locking pull rod 33.

[0053] The structure of the synchronous pull rod 6 needs to be determined based on the distribution of the locking components 3 on the battery swapping base 10 and the unlocking movement direction of each locking pull rod 33 in actual production.

[0054] In this embodiment, the synchronous action of the locking lever 33 is achieved by using the synchronous lever 6. The structure is simple and the operation is convenient. Compared with multiple people operating multiple locking levers 33 at the same time, or one person operating multiple locking levers 33 one after another, the locking and unlocking speed is faster.

[0055] In a specific embodiment, please refer to Figure 2 Four locking components 3 are symmetrically arranged at the four corners of the battery swapping base 10. The synchronous pull rod 6 includes a horizontal pull rod 61 and a vertical pull rod 62. The horizontal pull rod 61 is located between the locking pull rods 33 of the two locking components 3 at both ends of the width direction of the battery swapping base 10. The vertical pull rod 62 is used to connect the horizontal pull rod 61.

[0056] Preferably, one end of the synchronous pull rod 6 is provided with a pull handle 63, which is C-shaped. Both ends of the pull handle 63 are connected to the adjacent horizontal pull rod 61 so as to push and pull the synchronous pull rod 6.

[0057] The shape of the grip part of the pull handle 63 can be set according to ergonomics to improve the operator's operating comfort; preferably, a rubber protective cover is provided on the outside of the grip part of the pull handle 63. The rubber protective cover can increase the friction between the grip part and the hand on the one hand, and further improve the operating comfort on the other hand.

[0058] To prevent the synchronous pull rod 6 from deviating in the pushing and pulling direction, preferably, a guide sleeve 64 can be provided at the bottom of the battery swapping base. The guide sleeve 64 has a guide hole arranged along the length direction of the battery swapping base 10. The pull handle 63 is slidably installed in the guide hole. Thus, by utilizing the sliding cooperation between the guide hole and the guide sleeve 64, the pull handle 63 and the synchronous pull rod 6 are limited, preventing the movement direction of the synchronous pull rod 6 from deviating from the length direction of the battery swapping base 10.

[0059] 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.
