Description

Technical Field

[0001] This utility model relates to the field of battery swapping technology, and in particular to a battery base. Background Technology

[0002] Currently, in the field of electromechanical equipment, a technology for quick battery replacement has been developed, enabling rapid power replenishment. Specifically, a battery base is installed on the electromechanical equipment, and a locking mechanism is installed on the battery base to lock or unlock the battery box. When the battery box is depleted, the locking mechanism unlocks the battery box, facilitating its transfer using specialized lifting equipment. The lifting equipment then picks up a fully charged battery box and loads it onto the battery base, where the locking mechanism can then lock the battery box again. By installing a battery base on the electromechanical equipment, battery replacement and maintenance costs are reduced.

[0003] In related technologies, a battery base includes a base frame and a locking mechanism mounted on the base frame. The locking mechanism typically includes a guide body, a pin, and a cylinder. The guide body has a through groove, and the pin is slidably mounted in the through groove. The cylinder is located outside the guide body, and the cylinder and pin are in a driving engagement to drive the pin to slide out or retract along the through groove to perform locking or unlocking tasks. When the pin is engaged with the battery compartment, when an external force is applied to the pin, the pin tends to retract. When the external force is large enough, the pin may retract and detach from the battery compartment, causing the battery locking structure to fail and creating a safety hazard of the battery compartment falling off or tipping over.

[0005] The present invention adopts the following technical solution:

[0006] A battery holder, comprising:

[0007] Base body;

[0008] A guide body, the guide body being connected to the base body, the guide body having a cavity and a telescopic opening communicating with the cavity;

[0013] Optionally, a mating component is provided on the outer wall surface of the guide body near the edge of the base body;

[0014] With the battery box supported on the base body, the mating component elastically abuts against the battery box.

[0016] The bonding piece is attached to the outer wall surface of the guide body, and the convex shell protrudes outward from the guide body, with a smooth transition between the bonding piece and the convex shell.

[0017] Optionally, the two bonding pieces are arranged sequentially along the height direction of the guide body, and the bonding piece located at the top is fixed to the guide body by fasteners;

[0018] The bottom fitting piece and the outer wall surface of the guide can be slidably engaged.

[0024] Optionally, the battery base includes a guide sleeve;

[0025] The guide sleeve is fixed to the base body;

[0026] The telescopic component is slidably inserted into the guide sleeve.

[0027] Optionally, the guide sleeve includes a main sleeve body and a connecting plate connected to the main sleeve body;

Detailed Implementation

[0044] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

Therefore, they should not be construed as limitations on this utility model.

[0046] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0047] See Figures 1 to 6As shown, this application embodiment provides a battery holder, including: a base body 200, a guide body 300, and a locking mechanism 100. The guide body 300 is connected to the base body 200, and the guide body 300 has a cavity 320 and a telescopic opening 330 communicating with the cavity 320. The locking mechanism 100 includes a locking member 1, a telescopic assembly 2, and a connecting rod 3. The locking member 1 has a locking tongue and is at least partially located within the cavity 320. The locking member 1 is rotatably disposed on the base body 200 or the guide body 300. The telescopic assembly 2 is disposed on the base body 200 and has a telescopic member 21 that can translate linearly. One end of the connecting rod 3 is hinged to the telescopic member 21, and the other end of the connecting rod 3 is hinged to the locking member. The telescopic movement of the telescopic member 21 can drive the locking member 1 to swing through the connecting rod 3, so that the locking tongue 11 extends out of or retracts into the cavity 320 from the telescopic opening 330. When the locking tongue 11 extends out of the telescopic opening 330, the connecting rod 3 and the telescopic member 21 are perpendicular to each other.

[0048] When the locking mechanism 100 is in the state of locking the battery box, when an external force is applied to the locking tongue 11, the locking member 1 transmits the force to the connecting rod 3. The connecting rod 3 and the telescopic member 21 are perpendicular in the telescopic direction and are in a self-locking state. The telescopic member 21 will not move and retract, and the locking member remains in the locked state and will not be easily unlocked, thereby improving security.

[0049] In some possible implementations, the battery base includes a connecting shaft that passes through the locking member 1 and has its two ends respectively positioned on opposite wall shells of the guide body 300. The locking member 1 is rotatably mounted on the guide body 300 via the connecting shaft.

[0050] In some possible implementations, a mating part 400 is provided on the outer wall surface of the guide body 300 near the edge of the base body 200. When the battery box is supported on the base body 200, the mating part 400 elastically abuts against the battery box. The mating part 400 can be a metal sheet, which has the function of eliminating the gap between the battery box and the guide body 300, and helps to improve the assembly structure stability of the battery box.

[0051] In some possible implementations, the mating component 400 includes a convex shell portion 410 and fitting pieces 420 located on both sides of the convex shell portion 410. The fitting pieces 420 are fitted and connected to the outer wall surface of the guide body 300. The convex shell portion 410 protrudes outward from the guide body 300 to facilitate elastic abutment against the inner wall of the battery box bottom frame. The fitting pieces and the convex shell portion have a smooth transition, and the convex shell portion 410 and the fitting pieces 420 are integrally formed, resulting in good structural strength, durability, and resistance to breakage.

[0052] In some possible implementations, the two mating pieces 420 are arranged sequentially along the height direction of the guide body 300. The top mating piece 420 is fixed to the guide body 300 by fasteners, such as bolts. The bottom mating piece 420 is a free end, not fixed by fasteners, and slidably engages with the outer wall surface of the guide body 300. During the assembly of the battery box, the convex shell 410 is compressed, causing the bottom mating piece 420 to slide down the outer surface of the guide body 300, resulting in the overall deformation of the mating part 400, which then fits tightly between the battery box frame and the guide body.

[0053] In some possible implementations, the locking member 1 has a latch 11, a first extension 12, and a second extension 13, both of which are rotatably connected. The telescopic assembly 2 has a telescopic member 21, which is capable of linear translation, meaning it can only move in a straight line. One end of a connecting rod 3 is hinged to the telescopic member 21, and the other end is hinged to the first extension 12. The telescopic movement of the telescopic member 21 can drive the locking member 1 to swing via the connecting rod 3, causing the latch 11 to move to a locked or unlocked position. When the latch 11 is in the locked position, the connecting rod 3 and the telescopic member 21 are perpendicular. Figure 1 The state shown.

[0054] When the locking mechanism 100 is in the state of locking the battery box, when an external force is applied to the locking tongue 11, the locking member 1 transmits the force to the connecting rod 3. The connecting rod 3 and the telescopic member 21 are perpendicular to each other and are in a self-locking state. The telescopic member 21 will not move and retract, and the locking member remains in the locked state and will not be easily unlocked, thereby improving security.

[0055] In some possible implementations, such as Figure 1 As shown, a clearance recess 14 is formed between the first extension 12 and the second extension 13. When the latch 11 is moved to the locked position, the ends of the connecting rod 3 and the telescopic member 21 are located in the clearance recess 14.

[0056] It should be noted that the state in which the latch 11 moves to the locked position is approximately the position where the latch 11 extends the maximum distance, which is also the limit position of the swing of the locking member 1. In this embodiment, the extension directions of the first extension 12 and the second extension 13 on the locking member 1 are approximately perpendicular. A natural clearance recess is formed between them, thereby increasing the swing amplitude of the connecting rod 3, which is beneficial to achieving that the connecting rod 3 and the telescopic member 21 are perpendicular when the latch 11 moves to the locked position. The thickness end face of the first extension 12 and the second extension 13 on one side of the clearance recess 14 is a smoothly transitioned arc surface. This avoids severe friction with the end of the telescopic member 21, improving durability and reliability.

[0057] In some possible implementations, such as Figure 1 As shown, the first extension 12 and the latch 11 protrude in opposite directions, and the second extension 13 extends to a side perpendicular to the protruding direction of the first extension 12 to form the clearance recess 14 between the first extension 12 and the second extension 13. The first extension 12 is located between the latch 11 and the second extension 13. The locking member 1 has a simple overall structure. The first extension 12, the second extension 13, and the latch 11 are integrally formed.

[0058] In some possible implementations, such as Figure 1 and Figure 2 As shown, the first extension 12 includes two connecting pieces 121 spaced apart, with a gap between the two connecting pieces 121. One end of the connecting rod 3 extends into the gap and is rotatably connected to the two connecting pieces 121. The gap between the two connecting pieces 121 directly communicates with the relief recess 14, allowing the connecting pieces 121 to rotate into or extend out of the relief recess 14.

[0059] In some possible implementations, such as Figure 1 and Figure 2 As shown, the locking mechanism 100 includes a guide sleeve 4, the telescopic assembly 2 includes a telescopic drive member 22, and the telescopic member 21 is slidably inserted through the guide sleeve 4. The telescopic drive member 22 and the telescopic member 21 are connected to drive the telescopic member 21 to slide along the guide sleeve 4.

[0060] In this embodiment, the guide sleeve 4 can be fixed on the base body 200 of the battery base, which can restrict the movement trajectory of the telescopic member 21, so that the telescopic member 21 can only move in a straight line.

[0061] In some possible implementations, such as Figure 2 As shown, the guide sleeve 4 includes an outer sleeve 41 and an inner sleeve 42. The outer sleeve 41 is fitted onto the inner sleeve 42. A lubrication groove 421 is provided on the inner wall of the inner sleeve 42, and an oil injection groove is provided on the outer wall of the inner sleeve 42. The oil injection groove and the lubrication groove 421 are connected. The oil injection groove can be an annular groove provided on the outer wall of the inner sleeve 42. An opening is provided in the annular groove along the radial direction of the inner sleeve 42 to connect with the lubrication groove 421. An oil injection port 411 is provided on the outer sleeve 41 to connect with the oil injection groove. The telescopic member 21 is slidably inserted into the inner sleeve 42. Lubricating oil can be injected into the oil injection groove through the oil injection port 411. The lubricating oil will eventually enter the lubrication groove 421 on the inner wall of the inner sleeve 42, which helps to reduce the sliding resistance of the telescopic member 21.

[0062] In some possible implementations, such as Figure 2As shown, the telescopic member 21 has a slot 211 and a connecting groove 212. The slot 211 extends along the telescopic direction of the telescopic member 21, and the connecting groove 212 is perpendicular to the telescopic direction of the telescopic member 21 and communicates with the slot 211. The telescopic drive member 22 includes a main body 221 and a telescopic shaft 222 connected to the main body 221. The telescopic shaft 222 is inserted into the slot 211, and a pin passes through the connecting groove 212 and through the telescopic shaft 222. The telescopic drive member 22 can be a cylinder, and the telescopic shaft 222 is the movable shaft of the cylinder. The end of the movable shaft of the cylinder is inserted into the telescopic member 21 and connected to the telescopic member 21 by a pin.

[0063] In some possible implementations, the locking mechanism 100 includes an elastic element 23, which may be a spring, sleeved on the telescopic shaft 222, with its two ends abutting against the main body 221 and the telescopic member 21, respectively. When gas is injected into the cylinder, it drives the telescopic shaft 222 to move away from the locking member 1, the locking member 1 is in the unlocked state, and the elastic element 23 is in the compressed state. When the cylinder is depressurized, the elastic element 23 returns to its original deformation, pushing the telescopic member 21 towards the locking member 1, causing the locking member 1 to swing to the locked position.

[0064] In some possible implementations, the guide body 300 is connected to the base body 200, and the guide body 300 has a cavity 320 and a telescopic opening 330 communicating with the cavity 320. The guide body 300 is a hollow shell with an interior cavity 320, and the telescopic opening 330 is formed in the shell wall of the hollow shell, which communicates with the cavity 320 to allow the locking member 1 to extend or retract. The locking mechanism 100 includes a locking member 1, a telescopic assembly 2, and a connecting rod 3. The locking member 1 is at least partially located within the cavity 320 and is rotatably mounted on the base body 200 or the guide body 300. The telescopic assembly 2 is mounted on the base body 200 and has a telescopic member 21 that can translate linearly. One end of the connecting rod 3 is hinged to the telescopic member 21, and the other end of the connecting rod 3 is hinged to the first extension 12. The telescopic movement of the telescopic member 21 can drive the locking member 1 to swing through the connecting rod 3, causing the locking tongue 11 to extend or retract from the telescopic opening 330 into the cavity 320. When the locking tongue 11 extends out of the telescopic opening 330, the connecting rod 3 and the telescopic member 21 are perpendicular to each other.

[0065] In some possible implementations, the battery base includes a connecting shaft that passes through the locking member 1 and has its two ends respectively positioned on opposite wall shells of the guide body 300. The locking member 1 is rotatably mounted on the guide body 300 via the connecting shaft.

[0066] The battery holder of this application includes: a base body 200 and the aforementioned locking mechanism 100, wherein the second extension 13 of the locking member 1 of the locking mechanism 100 is rotatably connected to the base body 200, and the telescopic component 2 is disposed on the base body 200. Figure 5 and Figure 6 As shown, the battery base includes a support block 500, which is disposed on the base body 200 on the side of the locking member 1 near the telescopic component 2. When the locking tongue 11 is moved to the locked position, the connecting rod 3 or the telescopic component 21 abuts against the support block 500, and the support block 500 is located on the extension line of the connecting rod 3.

[0067] In some possible implementations, the support block 500 has a recess with a through groove in its bottom wall. One end of a fastener passes through the through groove and connects to the base body 200 or the guide body, while the other end of the fastener is accommodated within the recess. The fastener does not protrude from the recess and will not interfere with the connecting rod 3. The fastener can be a bolt.

[0068] like Figure 6 As shown, the telescopic member 21 has two support arms 213 at its end, and the end of the connecting rod 3 is located between the two support arms 213 and hinged to them. To protect the telescopic member 21 from bending and deformation due to the pressure of the connecting rod 3 (which forms a 90-degree angle with it) when the locking mechanism 100 is in the locked state, a support block 500 is provided at the bottom of the connecting rod 3, which contacts the outer arc of the connecting rod 3's outer contour. At this time, the reaction force applied by the battery box to the locking member 1 is transmitted to the support block 500 through the outer arc of the connecting rod 3. The horizontally moving telescopic member 21 will not be subjected to excessive downward bending force, thus protecting the telescopic member 21 and extending the product's service life.

[0069] The telescopic component 21 includes a main body section and two support arms 213 located at the ends of the main body section. A stepped surface 214 is formed between the support arms 213 and the main body section, meaning that there is a height difference between the support arms 213 and the main body section along the direction perpendicular to the base body 200, with the lower edge of the main body section being lower than the lower edge of the support arms 213, forming a stepped groove between them. When the locking mechanism 100 is in the locked state, the bottom end of the connecting rod 3 extends out of the support arm 213, that is, it extends into the stepped groove and can directly abut against the upper surface of the support block 500. The support block 500 is a rigid structure that can stably support the connecting rod 3 and prevent pressure from being applied to the telescopic component 21, causing the telescopic component 21 to bend and deform. The lower edge of the connecting rod 3 can be provided with an arc surface 31. During the swinging of the locking component 1 and the movement of the connecting rod 3, the arc surface 31 and the support block 500 slide in contact, which reduces wear and extends the service life. In this design, the lower edge of the thick end face of connecting rod 3 is set as an arc surface 31, while the two side plates of connecting rod 3 perpendicular to its thickness direction are flat surfaces. The flat surfaces and the arc surface 31 are connected and transitioned through the arc surface 31 or a slope. This prevents connecting rod 3 from cutting the bottom support block 500. A lubricating oil groove can be provided on the upper surface of the support block 500 to hold lubricating oil, allowing an oil film to cover the upper surface of the support block 500, reducing friction with connecting rod 3 and minimizing wear. Figure 6 In the state shown, with the latch 11 in the locked position, there is a gap between the step surface 214 and the support block 500 in the horizontal direction, i.e., the direction of movement of the telescopic member. The support block 500 does not support the main body of the telescopic member 21, reducing the force on the telescopic member 21. The support block 500 has end faces at both ends along the telescopic direction of the telescopic member 21. A chamfered surface or a rounded transition surface is formed between the end face and the top surface of the support block 500. This prevents severe rigid collisions that could cause serious damage if the main body comes into contact with the support block 500, thus improving reliability.

[0070] In some possible implementations, such as Figure 5 As shown, the system includes a support structure 600, which is fixed to the outer wall of the guide body 300. A support block 500 is fixed to the support structure 600 by fasteners. The guide body 300 has a side opening 310 communicating with a cavity 320. The locking member 1, the telescopic component 2, and the connecting rod 3 can pass through the side opening 310. The support structure 600 can be disposed on the guide body 300 at the lower edge of the side opening 310. The support block 500 passes through the side opening 310 and is located at the lower edge of the side opening 310. The support block 500 is supported on the thickness end faces of the support structure 600 and the lower edge of the side opening 310. The thickness end faces of the support structure 600 and the lower edge of the side opening cooperate to stably support the support block 500.

[0071] A slope is provided on the side of the support structure 600 near the outer wall of the guide body 300. This slope and the guide body 300 form a triangular cross-section groove, facilitating welding of the support structure 600 and the outer wall of the guide body 300 and allowing for filler solder. A bottom support rib 700 is also welded to the outer wall of the guide body 300. The bottom support rib 700 is vertically fixed to the base body 200, and its bottom can be welded to the base body 200. The top of the bottom support rib 700 directly supports the bottom of the support structure 600, providing reinforcement and increasing the load-bearing capacity of the support block 500.

[0072] In some possible implementations, such as Figure 4 As shown, a mating part 400 is provided on the outer wall surface of the guide body 300 near the edge of the base body 200. When the battery box is supported on the base body 200, the mating part 400 elastically abuts against the battery box. The mating part 400 can be a metal part, which has the function of eliminating the gap between the battery box and the guide body 300, and helps to improve the assembly structure stability of the battery box.

[0073] In some possible implementations, the mating part 400 includes a convex shell portion 410 and a mating piece portion 420 located on both sides of the convex shell portion 410. The mating piece portion 420 is mated to the outer wall surface of the guide body 300. The convex shell portion 410 protrudes outward from the guide body 300 to facilitate elastic abutment against the inner wall of the bottom frame of the battery box.

[0074] In some possible implementations, the two mating pieces 420 are arranged sequentially along the height direction of the guide body 300. The mating piece 420 located at the top is fixed to the guide body 300 by fasteners, while the guide body 300 located at the bottom is a free end and slidably engages with the outer wall surface of the guide body 300. During the assembly of the battery box, the convex shell 410 is compressed, causing the bottom mating piece 420 to slide down along the outer surface of the guide body 300, resulting in the mating part 400 being in an elastically deformed state.
