[0046] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0047] Reference below Figure 1-Figure 10 A handle structure 10 for a battery according to an embodiment of the present application is described. The handle structure 10 includes a cover body 11 and a handle body 12. The cover body 11 is arranged at the top end of a battery housing 20 and connected to the battery housing 20. A mounting surface 111 is formed at one end of the cover body 11 away from the battery housing 20. A receiving groove 112 that is recessed toward the inside is formed on the mounting surface 111. A movable connection portion 121 connected to the cover body 11 is provided at at least one end of the handle body 12. The movable connection portion 121 can be selectively moved relative to the cover body 11 to switch between a storage state and an expanded state; wherein in the storage state, the movable connection portion 121 is accommodated in the cover body 11 so that at least a portion of the handle body 12 is accommodated in the receiving groove 112; in the expanded state, the movable connection portion 121 protrudes from the cover body 11 so that the handle body 12 protrudes from the mounting surface 111.

[0048] At present, the commonly used fixed handles for power battery packs are fixedly connected to the brackets with rivets at both ends of the handles, and screw holes are punched at the corresponding positions of the battery aluminum shell and rigidly connected to the brackets. Although this fixed handle technology is mature and stable, in special demand scenarios, such as the narrow space of the electric motorcycle battery pack installation compartment and the high requirements for the volume energy density of the battery pack, the fixed handle has a large space occupancy rate and cannot meet the use requirements well.

[0049] like Figure 1 and Figure 2As shown, specifically, the handle structure 10 has a cover 11 and a handle body 12. The cover 11 can be arranged at the top of the battery housing 20, and the cover 11 is connected to the battery housing 20. In a specific embodiment, the cover 11 can be made of aluminum alloy, and the cover 11 and the battery housing 20 are fixed by welding. By adopting the welding fixing method, there is no need to open a threaded hole in the cover 11, which ensures the waterproofness and reliability of the battery, thereby improving the overall waterproofness of the battery. The end of the cover 11 away from the battery housing 20 can be formed with a mounting surface 111, and the mounting surface 111 is formed with a receiving groove 112 that is recessed toward the inside. The inside referred to here is the inside of the battery, and the receiving groove 112 can be formed by a die-casting process.

[0050] Further, at least one end of the handle body 12 is provided with a movable connection part 121, which refers to at least one end of the handle body 12 in the length direction. In a specific embodiment, both ends of the handle body 12 in the length direction are formed with movable connection parts 121, so as to ensure the stability of the handle body 12 during movement. Among them, the movable connection part 121 can be located at one end of the handle body 12 facing the receiving groove 112 and extending toward the cover body 11. The movable connection part 121 can be connected to the cover body 11, and the movable connection part 121 can move relative to the cover body 11, so as to switch between the storage state and the unfolded state. It should be explained that in order to ensure that the movable connection part 121 and the cover body 11 can move relative to each other, the connection method between the movable connection part 121 and the cover body 11 can be abutment.

[0051] The handle mechanism has a stowed state and an unfolded state. In the stowed state, the movable connection portion 121 can be accommodated inside the cover body 11, so that at least part of the handle body 12 is accommodated in the accommodating groove 112, thereby reducing the space occupied by the handle body 12 and improving the space utilization and energy density of the battery. In actual use, when the user does not need to lift the battery, the handle body 12 can be accommodated in the accommodating groove 112, and the upper surface of the handle body 12 and the mounting surface 111 can be located in the same horizontal plane or almost in the same horizontal plane, thereby ensuring the aesthetics of the handle mechanism and preventing foreign objects from being stuck between the handle body 12 and the mounting surface 111 and affecting the user's pulling of the handle body 12. The user can switch the handle mechanism from the storage state to the unfolded state by pulling the handle body 12. In the unfolded state, the movable connection part 121 can protrude from the cover body 11, so that the handle body 12 protrudes from the mounting surface 111. At this time, the user can lift the battery by using the handle body 12, and the movable connection part 121 protrudes from the cover body 11 so that the user can put his hand into the receiving groove 112 and pull up the handle body 12.

[0052] In short, the handle structure 10 for the battery of the present application comprises a cover body 11 and a handle body 12, a mounting surface 111 is formed on the cover body 11, a receiving groove 112 which is recessed inward is formed on the mounting surface 111, a movable connection portion 121 is formed on the handle body 12, and the movable connection portion 121 can drive the handle body 12 to switch between a storage state and an unfolded state. In the storage state, at least a portion of the handle body 12 can be accommodated in the receiving groove 112, thereby reducing the space occupancy rate of the handle body 12, improving the volume energy density of the battery, and meeting the actual use requirements.

[0053] like Figure 3 As shown, in some embodiments of the present application, a mounting groove 113 is formed on the mounting surface 111 and is recessed toward the inside. The mounting groove 113 and the receiving groove 112 can be arranged in sequence in the length direction of the handle body 12. In actual use, the mounting groove 113 can be configured as two and respectively located on both sides of the receiving groove 112 in the length direction. Among them, the receiving groove 112 can be configured as an arc-shaped groove, which can prevent the user from colliding with the inner wall of the receiving groove 112 when pulling the handle body 12 and causing damage. The mounting groove 113 and the receiving groove 112 can respectively play the role of installing and hiding the handle body 12.

[0054] Furthermore, the handle mechanism includes a limit assembly 13, which can be arranged in the mounting groove 113, and a receiving cavity 1311 is formed in the limit assembly 13, at least a portion of the movable connection part 121 can be accommodated in the receiving cavity 1311, and the movable connection part 121 can move in the receiving cavity 1311. It should be noted that the movable connection part 121 can move in the height direction of the receiving cavity 1311, and the receiving cavity 1311 can limit the sliding of the movable connection part 121 in the width direction, thereby achieving the function of limiting the movable connection part 121, wherein the movable connection part 121 can selectively abut against the inner wall of the limit assembly 13, thereby limiting the moving distance of the movable connection part 121, ensuring that the movable connection part 121 can effectively extend into the mounting groove 113, thereby hiding the movable connection part 121 and reducing the space occupied by the movable connection part 121.

[0055] like Figure 3As shown, in some embodiments of the present application, the movable connection part 121 can be located on the side of the handle body 12 facing the installation groove 113, and the movable connection part 121 can be extended toward the installation groove 113, and the free end of the movable connection part 121 is formed with a limit plate 122 extending away from each other, and the limit plate 122 can play a role of limiting the height direction. Specifically, a step surface 1321 is formed on the limit component 13, and the step surface 1321 can abut against the limit plate 122. In actual use, when the user pulls the handle body 12, the handle body 12 drives the movable connection part 121 to move, and the movable connection part 1 21 drives the limiting plate 122 to move. When the limiting plate 122 moves to a certain height, the outer surface of the limiting plate 122 contacts and abuts against the step surface 1321 of the limiting assembly 13, thereby limiting the movement of the limiting plate 122 and limiting the position of the handle body 12. It should be noted that the distance between the limiting plate 122 and the inner wall of the mounting groove 113 can be the distance that the handle body 12 can move. Therefore, in actual use, the user can adjust the height of the handle body 12 by changing the position of the limiting plate 122. The specific position of the limiting plate 122 can be set according to user needs and is not limited here.

[0056] like Figure 4 and Figure 5 As shown, in some embodiments of the present application, the limiting assembly 13 includes a fixing member 131 and a limiting member 132. The fixing member 131 can be arranged in the installation groove 113, and a receiving cavity 1311 can be formed in the fixing member 131. A through hole 1312 communicating with the receiving cavity 1311 is also formed on the fixing member 131. The movable connecting portion 121 can be passed through the through hole 1312 and accommodated in the receiving cavity 1311, so as to achieve the function of limiting the movable connecting portion 121. The limiting member 132 can be accommodated in the receiving cavity 1311, and the limiting member 132 can move in the receiving cavity 1311. The limiting member 132 can be formed with a step surface 1321 abutting against the limiting plate 122. The limiting member 132 can ensure that the handle body 12 does not rotate sideways or escape from the limiting area of ​​the fixing member 131.

[0057] In actual use, when the user pulls the handle body 12, the handle body 12 drives the limit plate 122 to move in the height direction. During the movement, the limit plate 122 also drives the limit member 132 to move in the accommodating cavity 1311 until the limit member 132 abuts against the inner wall of the fixing member 131, and the limit member 132 stops moving. At this time, the limit plate 122 abuts against the step surface 1321 of the limit member 132, thereby limiting the movement of the limit plate 122.

[0058] In a specific embodiment, the material of the fixing member 131 is A380 aluminum alloy, which has the advantages of easy mold casting, convenient machining, good thermal conductivity, good pressure resistance and high temperature resistance. The stopper 132 has certain wear resistance, hardness and strength to prevent the stopper 132 from deforming when subjected to force or being damaged by long-term sliding and causing functional failure.

[0059] like Figure 6 and Figure 7 As shown, in some embodiments of the present application, the inner wall of the mounting groove 113 is formed with a first protrusion 1131 extending toward the fixing member 131, and a first thread groove 1132 is formed in the first protrusion 1131. A first fastener 133 is formed on the fixing member 131, and the first fastener 133 can cooperate with the first thread groove 1132. By threading the first fastener 133 with the first thread groove 1132, the fixing member 131 is installed in the mounting groove 113. Specifically, the first fastener 133 needs to have the functions of loosening and anti-disassembly. Therefore, the first fastener 133 is constructed as an M4 hexagon socket screw with a built-in spring washer and flat washer. Furthermore, the first protrusion 1131 can be constructed as a plurality of first protrusions 1131, and a plurality of first protrusions 1131 can be arranged on the inner wall of the mounting groove 113. The first fastener 133 can be constructed as a plurality of first protrusions 1131 arranged in a one-to-one correspondence with the plurality of first protrusions 1131. The use of a plurality of first protrusions 1131 and a plurality of first fasteners 133 can improve the connection strength between the fixing member 131 and the mounting groove 113.

[0060] like Figure 8As shown, in some embodiments of the present application, the limiting assembly 13 further includes a baffle 134, which can be arranged on at least one side of the fixing member 131 in the length direction of the handle body 12, and the baffle 134 can be connected to the fixing member 131. In a specific embodiment, the baffle 134 is made of metal. Optionally, the shape of the baffle 134 matches the shape of the fixing member 131, and the baffle 134 and the fixing member 131 are detachably connected by bolts and threads, or the baffle 134 and the fixing member 131 are detachably connected by snapping or plugging, or the contact surface between the baffle 134 and the fixing member 131 is directly welded. In a specific implementation, the fixing member 131 is formed with a first threaded hole 1313 extending in the length direction, and the baffle 134 is formed with a second threaded hole 1341 arranged opposite to the first threaded hole 1313, and the first threaded hole 1313 and the second threaded hole 1341 can be threadedly connected by a third fastener 135. The baffle plate 134 and the limiting plate 122 can abut against each other in the length direction, thereby limiting the movement of the limiting plate 122 in the length direction, thereby limiting the length direction of the handle body 12. The third fastener 135 is used to lock the baffle plate 134 to the fixing member 131. In order to ensure that the third fastener 135 does not occupy the space of the handle body 12, the third fastener 135 is a countersunk screw, and the strength grade of the third fastener 135 needs to meet grade 8.8 or above.

[0061] like Fig.10 As shown, in some embodiments of the present application, the handle structure 10 further includes a guide member 14, which can be disposed in the mounting groove 113, and the guide member 14 can be connected to the inner wall of the mounting groove 113, and a guide surface 141 is formed on the outer periphery of the guide member 14, and a guide groove 123 which is recessed toward the inside can be formed in the movable connection portion 121, and when the user switches the handle structure 10 from the unfolded state to the stowed state, the inner wall of the guide groove 123 can be fitted with the guide surface 141, and the guide groove 123 and the guide member 14 can be transitionally matched, so that the guide member 14 can provide an axial guiding function for the movement of the handle body 12, facilitate the reset of the handle body 12, and prevent the deviation of the handle body 12. Specifically, in the direction in which the guide member 14 is away from the inner wall of the mounting groove 113, the outer diameter of the guide member 14 gradually decreases to form a guide surface 141, and the guide surface 141 is configured as an inclined surface, which is conducive to the reset of the handle body 12, and the reset of the handle body 12 effectively provides a guiding function. Specifically, the guide member 14 can be made of a material having high temperature resistance, wear resistance, aging resistance and self-lubricating properties, such as nylon resin.

[0062] In some embodiments of the present application, a reset member is provided between one end of the guide member 14 away from the mounting groove 113 and the inner wall of the guide groove 123. Specifically, the reset member can be constructed as a magnetic member, and the reset member can be attached to one end of the guide member 14. The handle body 12 can be constructed as a metal member. When the user switches the handle structure 10 from the deployed state to the stored state, the reset member can magnetically absorb the handle body 12, thereby resetting the handle body 12. In other embodiments of the present application, the reset member can be constructed as a spring. When the user switches the handle structure 10 from the deployed state to the stored state, the reset member pulls the handle body 12 toward the guide member 14 under the influence of the elastic force of the spring, thereby realizing the reset function of the handle body 12.

[0063] like Figure 3 and Figure 6 As shown, in some embodiments of the present application, a second protrusion 1133 is formed on the inner wall of the mounting groove 113, and the second protrusion 1133 can be extended toward the handle body 12, and a second thread groove 1134 is formed in the second protrusion 1133. A second fastener 142 is formed on the guide member 14, and the second fastener 142 can cooperate with the second thread groove 1134. The guide member 14 is installed in the mounting groove 113 by threading the second fastener 142 with the second thread groove 1134. Specifically, the second fastener 142 is constructed as a screw, and the size of the screw is determined by the size of the second thread groove 1134. The strength grade of the screw needs to meet grade 8.8 or above.

[0064] In some embodiments of the present application, the handle body 12 can be composed of a high-elastic steel frame and a TPU (thermoplastic polyurethane rubber) rubber coating. The high-elastic steel frame can produce elastic deformation under the weight of the battery itself, which improves the comfort of the user when using it, and the high-elastic steel frame ensures that the handle body 12 can automatically return to its original position after the tension is released. Each time the handle body 12 is extended by force, the rebound is directional after the force is released, thereby effectively ensuring the consistency of the outer dimensions of the handle body 12. The rubber coating is a fold-resistant soft TPU material. The TPU rubber coating has the advantages of wear resistance, oil resistance and aging resistance. The TPU rubber coating can improve the friction and touch of the handle body 12. In addition, the TPU rubber coating also has good resilience, shock absorption performance and anti-slip performance. In order to ensure that the battery module needs to have the functions of waterproof, dustproof and extrusion-proof, the battery housing 20 is formed by processing aluminum alloy material as a whole. In other embodiments, the rubber coating material of the handle body 12 needs to be fold-resistant, aging-resistant, and soft to a certain extent, to ensure that the handle body 12 does not come apart during long-term use. In addition, the material of the handle body 12 can be based on the load-bearing conditions. On the premise of meeting the use conditions, the material of the handle body 12 can consider engineering plastics, magnesium alloys, and other materials with high specific strength, thereby reducing the overall weight and improving installation operability.

[0065] like Fig. 9 As shown, a weight-reducing groove 124 is formed on the side of the handle body 12 away from the mounting groove 113. The weight-reducing groove 124 can be constructed in multiples. In a specific embodiment, the weight-reducing groove 124 can be constructed as a concave honeycomb hole structure. The weight-reducing groove 124 can reduce the overall weight of the handle structure 10, and the weight-reducing groove 124 can also increase the flexibility of the handle body 12, thereby improving the comfort of the handle body 12 when in use.

[0066] like Fig. 9 As shown, a handle surface 125 is formed on one side of the handle body 12 facing the mounting groove 113. The handle surface 125 can be constructed as a wavy surface. The wavy surface can increase the contact area between the handle surface 125 and the user's palm, thereby increasing the friction between the palm and the handle body 12, ensuring the anti-slip effect of the handle body 12 and improving the reliability of the handle structure 10. At the same time, the wavy surface conforms to the ergonomic design, which improves the comfort of the palm when carrying batteries.

[0067] In a specific embodiment of the present application, the guide member 14 is screwed to the second protrusion 1133 of the cover body 11 and embedded in the guide groove 123 of the handle body 12. The movable connection parts 121 on both sides of the handle body 12 are assembled with the limit members 132 to form a sliding fit, and then the fixing member 131 is screwed to the cover body 11, and the baffle 134 is rigidly connected to the fixing member 131 by screws, and then the above structure is embedded therein to complete the installation of the handle structure 10. When the user extracts and carries the battery, the handle body 12 and the limit member 132 move upward under the action of tension, and are blocked by the fixing member 131 after reaching the highest limit position.
