Description

Technical Field

[0001] The utility model relates to the field of battery packs, in particular to a handle structure for a battery pack and the battery pack. Background Art

[0002] In recent years, with the rapid development of the new energy battery industry, the use of lithium batteries has become increasingly widespread. For example, in the field of new energy electric vehicles, as the range of electric vehicles increases, the requirements for the storage capacity of electric vehicle battery packs are further improved. In order to improve the storage capacity of battery packs, the size of battery packs is getting bigger and bigger, and the weight of battery packs is getting heavier. Therefore, it is necessary to add handles to the battery packs to improve the convenience of carrying the battery packs.

[0003] However, the industry generally uses aluminum alloy die-cast handles, and the handle flip angle is generally set to 90°, so that the battery pack can be lifted or lowered by the handle when needed. When an electric vehicle is driving over a bumpy road, the handle will usually vibrate excessively due to the shaking of the electric vehicle body, thereby hitting the outer shell of the battery pack and generating noise. In order to solve the problem of noise generated by the handle of the battery pack, the traditional approach is to add interference material (such as soft rubber material) for buffering at the rotating connection between the battery pack and the handle, thereby increasing the friction at the rotating connection between the battery pack and the handle to reduce the vibration freedom of the handle, thereby achieving the effect of reducing the noise generated by the vibration of the handle. However, this method also has the following problems: in the long-term use of soft rubber materials, the interference material will be gradually worn away by friction, resulting in the failure of the interference material, and eventually it will still cause excessive vibration of the handle and generate noise.

[0038] See also Figures 1 to 4 In order to better understand the handle structure 10 for the battery pack of the present application, the handle structure 10 for the battery pack is further explained below:

[0039] A handle structure 10 for a battery pack according to one embodiment includes an upper cover 100, a gripping piece 200 and a limiting assembly 300. The upper cover 100 is provided with a placement groove 101, and a penetration opening 102 is provided at the bottom of the placement groove 101. The gripping piece 200 is provided with a penetration hole 201. The limiting assembly 300 includes a positioning damping metal ring 310, a rotation damping metal ring 320 and a fastener 330, one end of the positioning damping metal ring 310 is arranged in the placement groove 101, the other end of the positioning damping metal ring 310 is provided with a limiting protrusion 3110, one end of the rotation damping metal ring 320 is connected to the gripping piece 200, the rotation damping metal ring 320 is provided with a limiting groove 3201, the limiting protrusion 3110 is arranged in the limiting groove 3201, and the The limiting protrusion 3110 is movably connected to the limiting groove 3201, one end of the fastener 330 is arranged in the penetration opening 102, and the other end of the fastener 330 is arranged in the limiting penetration hole 201, the positioning damping metal ring 310 and the rotating damping metal ring 320 are both sleeved on the fastener 330 so that the other end of the positioning damping metal ring 310 abuts against the other end of the rotating damping metal ring 320, and the holding piece 200 is rotatably connected to the upper cover 100.

[0040] In this embodiment, one end of the fastener 330 is arranged in the penetration opening 102, and the other end of the fastener 330 is arranged in the limiting penetration hole 201, and then the positioning damping metal ring 310 and the rotating damping metal ring 320 are both sleeved on the fastener 330, so that the other end of the positioning damping metal ring 310 abuts against the other end of the rotating damping metal ring 320, thereby realizing the rotational connection between the grip 200 and the upper cover 100. Since there is abutment contact between the other end of the positioning damping metal ring 310 and the other end of the rotating damping metal ring 320, when the holding piece 200 is flipped, the friction force of the abutment contact between the positioning damping metal ring 310 and the rotating damping metal ring 320 can be effectively increased, and the magnitude of the friction force can be adjusted by adjusting the tightness of the fastener 330. At the same time, the structural stability of the positioning damping metal ring 310, the rotating damping metal ring 320 and the holding piece 200 can be increased. In this way, by increasing the magnitude of the friction force, the vibration freedom of the holding piece 200 can be effectively reduced, thereby effectively avoiding the problem of noise generated by excessive vibration of the holding piece 200.

[0041] Furthermore, since one end of the positioning damping metal ring 310 is arranged in the placement groove, the other end of the positioning damping metal ring 310 is provided with a limiting protrusion 3110, and one end of the rotating damping metal ring 320 is connected to the holding piece 200, the rotating damping metal ring 320 is provided with a limiting groove 3201, that is, by arranging the limiting protrusion 3110 in the limiting groove 3201, and the limiting protrusion 3110 is movably connected with the limiting groove 3201, the rotating damping metal ring 320 can rotate synchronously with the flipping of the holding piece 200. Since the positioning damping metal ring 310 is fixed and the limiting protrusion 3110 is movably connected to the limiting groove 3201, the limiting protrusion 3110 can effectively limit the rotation angle of the limiting groove 3201. This can effectively limit the flipping angle of the holding piece 200, and further avoid the situation where the flipping angle of the holding piece 200 is too large and causes the holding piece 200 to hit the outer shell of the battery pack and cause vibration.

[0042] like Figures 1 to 4 As shown, in one embodiment, the number of the limiting protrusions 3110 is two, namely a first limiting protrusion 3110a and a second limiting protrusion 3110b;

[0043] There are two limiting grooves, namely a first limiting groove 3201a and a second limiting groove 3201b. The first limiting protrusion 3110a is arranged in the first limiting groove 3201a, and the second limiting protrusion 3110b is arranged in the second limiting groove 3201b. It can be understood that since the first limiting protrusion 3110a is arranged in the first limiting groove 3201a and the second limiting protrusion 3110b is arranged in the second limiting groove 3201b, the first limiting protrusion 3110a is movably connected to the first limiting groove 3201a, and the second limiting protrusion 3110b is movably connected to the second limiting groove 3201b, so that the first limiting protrusion 3110a can effectively limit the rotation angle of the first limiting groove 3201a, and the second limiting protrusion 3110b can effectively limit the rotation angle of the second limiting groove 3201b, thereby effectively limiting the flipping angle of the gripping member 200.

[0044] It should be noted that by adjusting the opening angles of the first limiting groove 3201a and the second limiting groove 3201b and combining the limiting effects of the first limiting protrusion 3110a and the second limiting protrusion 3110b, the rotation angles of the first limiting groove 3201a and the second limiting groove 3201b can be limited at the same time. Since the rotation damping metal ring 320 rotates synchronously with the flipping of the grip 200, limiting the rotation angles of the first limiting groove 3201a and the second limiting groove 3201b is equivalent to limiting the flipping angle of the grip 200. Those skilled in the art can also adjust the opening angles of the first limiting groove 3201a and the second limiting groove 3201b accordingly according to the actual use requirements of the grip 200. For example, the opening angle of the first limiting groove 3201a and the second limiting groove 3201b is 180°, and the flipping angle of the gripping member 200 is 180°, so the opening angle range of the first limiting groove 3201a and the second limiting groove 3201b can be between 0°-180°.

[0045] It should be noted that the positioning damping metal ring 310 and the rotating damping metal ring 320 of the utility model of the present application are made of metal materials with good elastic properties and surface friction coefficient (such as 316 stainless steel), which can effectively improve the durability of the positioning damping metal ring 310 and the rotating damping metal ring 320 when the grip 200 is flipped, and the use of metal materials with good elastic properties can effectively reduce the negative effects caused by the vibration of the mechanical structure.

[0046] It should also be noted that by creating friction between the other end of the positioning damping metal ring 310 and the other end of the rotating damping metal ring 320, the vibration amplitude of the grip 200 can be reduced, thereby effectively reducing the vibration freedom of the grip 200.

[0047] like Figures 1 to 4 As shown, in one embodiment, the number of the placement grooves 101 is two, namely the first placement groove 101a and the second placement groove 101b. The first placement groove 101a is provided at one end of the upper cover 100, and the second placement groove 101b is provided at the other end of the upper cover 100. The bottom of the first placement groove 101a is provided with a first penetration opening 102a, and the bottom of the second placement groove 101b is provided with a second penetration opening 102b. In one embodiment, the number of the position-limiting penetration holes 201 is two, and the first position-limiting penetration hole 201a is provided at one end of the grip 200, and the second position-limiting penetration hole 201b is provided at the other end of the grip 200;

[0048] The number of the fasteners 330 is two, namely the first fastener 330a and the second fastener 330b. It can be understood that the upper cover 100 is symmetrically provided with the first placement groove 101a and the second placement groove 101b, and by respectively setting one end of the first fastener 330a at the first penetration opening 102a, the other end of the first fastener 330a at the first position-limiting penetration hole 201a, one end of the second fastener 330b at the second penetration opening 102b, and the other end of the second fastener 330b at the second position-limiting penetration hole 201b, the grip 200 can be rotatably connected to the upper cover 100.

[0049] It should be noted that both the first through-hole 102a and the second through-hole 102b are provided with internal threads, and one end of the first fastener 330a and one end of the first fastener 330b are provided with external threads. By connecting one end of the first fastener 330a to the first through-hole 102a and one end of the first fastener 330b to the second through-hole 102b respectively, the other end of the positioning damping metal ring 310 and the other end of the rotating damping metal ring 320 are more compactly abutted, which can effectively increase the structural stability of the positioning damping metal ring 310, the rotating damping metal ring 320 and the holding piece 200.

[0050] like Figures 1 to 4 As shown, in one embodiment, the number of the positioning damping metal rings 310 is two, namely a first positioning damping metal ring 310a and a second positioning damping metal ring 310b;

[0051] The number of the rotation damping metal rings 320 is two, namely a first rotation damping metal ring 320a and a second rotation damping metal ring 320b. In one embodiment, a first fixing slot 202 is formed at one end of the gripping member 200;

[0052] A first protrusion 3210a is formed at one end of the first rotation damping metal ring 320a, and the first protrusion 3210a is disposed in the first fixing slot 202. In one embodiment, a second fixing slot 203 is formed at the other end of the gripping member 200;

[0053] A second protrusion 3210 b is formed at one end of the second rotation damping metal ring 320 b , and the second protrusion 3210 b is disposed in the second fixing slot 203 .

[0054] It should be noted that since the first protrusion 3210a is arranged in the first fixed slot 202 and the second protrusion 3210b is arranged in the second fixed slot 203, when the holding piece 200 is flipped, the first rotation damping metal ring 320a and the second rotation damping metal ring 320b can rotate synchronously with the flipping of the holding piece 200.

[0055] like Figures 1 to 4 As shown, in one embodiment, a first groove 102a is formed on the periphery of the first placement slot 101a;

[0056] A first positioning protrusion 3120a is formed at one end of the first positioning damping metal ring 310a, and the first positioning protrusion 3120a is disposed in the first groove 102a. In one embodiment, a second groove 102b is formed at the periphery of the second placement groove 101b;

[0057] A second positioning protrusion 3120b is formed at one end of the second positioning damping metal ring 310b, and the second positioning protrusion 3120b is arranged in the second groove 102b. It can be understood that by respectively arranging the first positioning protrusion 3120a in the first groove 102a and the second positioning protrusion 3120b in the second groove 101b, the first positioning damping metal ring 310a and the second positioning damping metal ring 310b can be fixed, so that the first limiting protrusion 3110a and the second limiting protrusion 3110b are fixed, and the first limiting groove 3201a and the second limiting groove 3201b are limited, so that the flip angle of the grip 200 can be effectively limited.

[0058] The present application also provides a battery pack, comprising the handle structure for the battery pack described in any of the above embodiments.

[0059] In this embodiment, one end of the fastener is arranged in the penetration opening, the other end of the fastener is arranged in the limiting penetration hole, and then the positioning damping metal ring and the rotation damping metal ring are both sleeved on the fastener, so that the other end of the positioning damping metal ring abuts against the other end of the rotation damping metal ring, thereby realizing the rotation connection between the grip and the upper cover. Since there is abutment contact between the other end of the positioning damping metal ring and the other end of the rotation damping metal ring, when the grip is flipped, the friction force of the abutment contact between the positioning damping metal ring and the rotation damping metal ring can be effectively increased, and the magnitude of the friction force can be adjusted by adjusting the tightness of the fastener, and the structural stability of the positioning damping metal ring, the rotation damping metal ring and the grip can also be increased. In this way, by increasing the magnitude of the friction force, the vibration freedom of the grip can be effectively reduced, and the problem of noise generated by excessive vibration of the grip can be effectively avoided.

[0060] Furthermore, since one end of the positioning damping metal ring is arranged in the placement groove, the other end of the positioning damping metal ring is provided with a limiting protrusion, and one end of the rotating damping metal ring is connected to the gripping member, the rotating damping metal ring is provided with a limiting groove, that is, by arranging the limiting protrusion in the limiting groove, and the limiting protrusion is movably connected to the limiting groove, the rotating damping metal ring can be synchronously rotated with the flipping of the gripping member. Since the positioning damping metal ring is fixed, and the limiting protrusion is movably connected to the limiting groove, the limiting protrusion can effectively limit the rotation angle of the limiting groove, so that the flipping angle of the gripping member can be effectively limited, and further the flipping angle of the gripping member can be prevented from being too large, causing the gripping member to hit the outer shell of the battery pack and cause vibration.

[0061] Compared with the prior art, the utility model has at least the following advantages:

[0062] 1. By setting one end of the fastener in the penetration opening, and the other end of the fastener in the limiting penetration hole, and then sleeve the positioning damping metal ring and the rotating damping metal ring on the fastener, so that the other end of the positioning damping metal ring abuts against the other end of the rotating damping metal ring, the gripping piece and the upper cover are rotatably connected. Since there is abutment contact between the other end of the positioning damping metal ring and the other end of the rotating damping metal ring, when the gripping piece flips over, the friction force of the abutment contact between the positioning damping metal ring and the rotating damping metal ring can be effectively increased, and the magnitude of the friction force can be adjusted by adjusting the tightness of the fastener, and the structural stability of the positioning damping metal ring, the rotating damping metal ring and the gripping piece can also be increased. In this way, by increasing the magnitude of the friction force, the vibration freedom of the gripping piece can be effectively reduced, and the problem of noise generated by excessive vibration of the gripping piece can be effectively avoided.

[0063] 2. Since one end of the positioning damping metal ring is arranged in the placement groove, the other end of the positioning damping metal ring is provided with a limiting protrusion, and one end of the rotating damping metal ring is connected to the gripping piece, the rotating damping metal ring is provided with a limiting groove, that is, by arranging the limiting protrusion in the limiting groove, and the limiting protrusion is movably connected to the limiting groove, the rotating damping metal ring can be synchronously rotated with the flipping of the gripping piece. Since the positioning damping metal ring is fixed and the limiting protrusion is movably connected to the limiting groove, the limiting protrusion can effectively limit the rotation angle of the limiting groove, so that the flipping angle of the gripping piece can be effectively limited, and further, it can be avoided that the flipping angle of the gripping piece is too large, causing the gripping piece to hit the outer shell of the battery pack and cause vibration.

[0064] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
