Description

Technical Field

[0001] This utility model relates to the field of battery carriers, and more particularly to a carrier and a drive mechanism. Background Technology

[0002] As a power supply device, the battery mainly consists of a cell and a circuit board. The circuit board is located on one end of the cell, with one end connected to the cell and the other end having connection terminals for connecting to electrical equipment. During battery assembly, after the carrier carries the battery to a fixed workstation, a gripping device simultaneously grips both the cell and the connection terminals to remove the battery from the carrier. The gripping actions of the gripping device (e.g., the movement path of the robotic arm) are pre-set.

[0003] Due to manufacturing and assembly errors, the end containing the connecting terminal may be tilted relative to the battery cell. In related technologies, when the circuit board is short, the tilt height of the connecting terminal end relative to the battery cell is within a controllable range, allowing the gripping device to simultaneously grasp both the battery cell and the connecting terminal. However, as the circuit board length increases, the tilt height of the connecting terminal end exceeds the gripping device's grasping range, leading to the gripping device failing to grasp the battery. Utility Model Content

[0004] This utility model discloses a carrier and a drive mechanism to solve the problem in related technologies where gripping devices often fail to grip batteries located on the carrier.

[0005] To solve the above-mentioned technical problems, this utility model is implemented as follows:

[0006] In a first aspect, this application discloses a carrier for carrying a battery, the battery including a cell and a circuit board disposed on a first end face of the cell, the carrier including a carrier body and a clamping part, the carrier body having a carrying area for carrying the battery, the clamping part being movably disposed on the carrier body and spaced apart from the carrying area, the clamping part having a first position and a second position;

[0007] When the clamping part is in the first position, the clamping part is used to press the circuit board onto the first end face of the battery cell;

[0008] When the clamping part is in the second position, the clamping part is used to separate from the circuit board.

[0009] Secondly, this application also discloses a driving mechanism for cooperating with the carrier described in the first aspect. The driving mechanism includes a driving body and a toggle member connected to the driving body. The driving body drives the toggle member to extend into the toggle groove and drives the clamping part to rotate to a third position or a fourth position via the toggle member. The third position and the fourth position are both located between the first position and the second position. In the third position, the elastic force of the elastic member driving the clamping part is greater than the magnetic attraction force between the magnetic member and the clamping part. In the fourth position, the elastic force of the elastic member driving the clamping part is less than the magnetic attraction force between the magnetic member and the clamping part.

[0010] The technical solution adopted in this utility model can achieve the following technical effects:

[0011] The carrier disclosed in this application has a clamping part on its body. When the carrier body fixes the battery in the bearing area, the clamping part can move to a first position, pressing the circuit board onto the first end face of the battery cell. Since the position of the battery cell is fixed on the carrier body, the position of the circuit board after pressing it onto the first end face of the battery cell is also fixed, and therefore the position of the connection terminals on the circuit board is also fixed. With the positions of the battery cell and the connection terminals both fixed, the gripping device can accurately grip the battery cell and the connection terminals, thereby improving the accuracy of the gripping device in gripping the battery.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] The technical solutions disclosed in the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0026] Please refer to Figures 1 to 4 This utility model discloses a carrier for carrying battery A.

[0027] Battery A includes a cell A1 and a circuit board A2 disposed on the first end face of the cell A1. The first end face of the cell A1 refers to an end face perpendicular to the thickness direction of the cell A1.

[0028] The carrier includes a carrier body 100 and a clamping part 200. The carrier body 100 has a carrying area for carrying the battery A. The carrier can carry the battery A through the carrying area, and the carrying area can be provided with a vacuum suction cup 110. The carrier can fix the battery A to the carrying area through the vacuum suction cup.

[0029] The clamping part 200 is movably disposed on the carrier body 100, and the clamping part 200 is spaced apart from the bearing area. The clamping part 200 has a first position and a second position.

[0030] When the clamping part 200 is in the first position, the clamping part 200 is used to press the circuit board A2 onto the first end face of the battery cell A1. When the clamping part 200 is in the second position, the clamping part 200 is used to separate from the circuit board A2.

[0031] It should be noted that the switching of the clamping part 200 between the first position and the second position can be achieved by manual drive or by drive mechanism 600. This embodiment of the application does not impose specific restrictions on the driving method for switching the clamping part 200 between the first position and the second position. The clamping part 200 can be movably disposed on the carrier body 100 or rotatably disposed on the carrier body 100. This embodiment of the application does not impose specific restrictions on the arrangement of the clamping part 200.

[0032] The carrier disclosed in this application provides a clamping part 200 on the carrier body 100. When the carrier body 100 fixes the battery A in the bearing area, the clamping part 200 can move to a first position, pressing the circuit board A2 onto the first end face of the battery cell A1. Since the position of the battery cell A1 is fixed on the carrier body 100, the position of the circuit board A2 is also fixed after pressing it onto the first end face of the battery cell A1. Therefore, the position of the connecting terminals on the circuit board A2 is also fixed. With the positions of the battery cell A1 and the connecting terminals both determined, the gripping device can accurately grip the battery cell and the connecting terminals, thereby improving the accuracy of the gripping device in gripping the battery A.

[0033] When the gripping device grabs the battery, the clamping part 200 can move to the second position, thereby releasing the circuit board A2, and the vacuum suction cup 110 can stop adsorbing the battery cell A1, so that the gripping device can pick up the battery A.

[0034] In order to keep the clamping part 200 in the first position to keep the circuit board A2 pressed on the first end face of the battery cell A1, optionally, when the clamping part 200 is driven to move to the first position by the driving mechanism, the driving mechanism can stop driving after the clamping part 200 moves to the first position, and keep the clamping part 200 in the first position under the action of the driving mechanism 600.

[0035] In another embodiment, the carrier may further include an elastic element that can be connected between the carrier body 100 and the clamping part 200, and the elastic element can be used to drive the clamping part 200 to remain in a first position.

[0036] Specifically, when the clamping part 200 is in the first position, the elastic member can apply an elastic force to the circuit board A2 to press the circuit board A2 onto the first end face of the battery cell A1, thereby allowing the elastic member to drive the clamping part 200 to remain in the first position. Since the clamping part 200 is driven to remain in the first position by the elastic member, the carrier structure is relatively simple.

[0037] In order to keep the clamping part 200 in the second position, optionally, when the clamping part 200 is driven to move to the second position by the drive mechanism 600, the drive mechanism 600 can stop driving after the clamping part 200 moves to the second position, and keep the clamping part 200 in the second position under the action of the drive mechanism 600.

[0038] In another embodiment, the carrier may further include a magnetic element 400, which may be disposed on the carrier body 100 and magnetically engage with the clamping portion 200. When the clamping portion 200 is in a first position, the elastic force of the elastic element driving the clamping portion 200 may be greater than the magnetic attraction force between the magnetic element 400 and the clamping portion 200, so that the clamping portion 200 is held in the first position. When the clamping portion 200 is in a second position, the elastic force of the elastic element driving the clamping portion 200 may be less than the magnetic attraction force between the magnetic element 400 and the clamping portion 200, so that the clamping portion 200 is held in the second position.

[0039] It should be noted that when the clamping part 200 moves, it causes the elastic element to undergo elastic deformation. Simultaneously, it changes the distance between itself and the magnetic element 400, thereby altering the magnitude of the magnetic attraction between the clamping part 200 and the magnetic element 400. Therefore, when the clamping part 200 moves from the second position to the first position, initially the elastic force of the elastic element driving the clamping part 200 is less than the magnetic attraction between the magnetic element 400 and the clamping part 200. At a certain position, the elastic force of the elastic element driving the clamping part 200 becomes equal to the magnetic attraction between the magnetic element 400 and the clamping part 200. As the clamping part 200 continues to move, the elastic force of the elastic element driving the clamping part 200 becomes greater than the magnetic attraction between the magnetic element 400 and the clamping part 200.

[0040] Therefore, when the clamping part 200 moves from the second position to the first position, the operator or the drive mechanism 600 only needs to drive the clamping part 200 to a position where the elastic force of the elastic member driving the clamping part 200 is greater than the magnetic attraction force between the magnetic member 400 and the clamping part 200 (for example, the third position mentioned later). After that, the clamping part 200 can move to the first position under the action of the elastic force of the elastic member and remain in the first position. When the clamping part 200 moves from the first position to the second position, the operator or the drive mechanism 600 only needs to drive the clamping part 200 to a position where the elastic force of the elastic member driving the clamping part 200 is less than the magnetic attraction force between the magnetic member 400 and the clamping part 200 (for example, the fourth position mentioned later). After that, the clamping part 200 can move to the second position under the action of the magnetic attraction force of the magnetic member 400 and remain in the second position.

[0041] Specifically, the first end of the clamping part 200 can be used to cooperate with the circuit board A2, and the second end of the clamping part 200 can be used to cooperate with the magnetic component 400. The clamping part 200 is rotatably disposed on the carrier body 100 via a rotating shaft 210, which can be located between the first end and the second end of the clamping part 200. When the clamping part 200 rotates from the second position to the first position along the first direction, the first end of the clamping part 200 presses the circuit board A2 onto the first end face of the battery cell A1. When the clamping part 200 rotates from the first position to the second position along the second direction, the first end of the clamping part 200 separates from the circuit board A2. The first direction can be opposite to the second direction.

[0042] Of course, the clamping part 200 can also be movably provided on the carrier body 100. The clamping part 200 can be opposite to the board surface of the circuit board A2. The clamping part 200 can move along the side close to or away from the circuit board A2, thereby realizing the switching of the clamping part 200 between the first position and the second position.

[0043] The elastic element can be elastic rubber, a coil spring, etc. In another embodiment, the elastic element may include a torsion spring 300, which is connected between the carrier body 100 and the clamping part 200, and the torsion spring 300 may be sleeved on the rotating shaft 210.

[0044] The vehicle disclosed in this application embodiment has a structure that includes a torsion spring 300 in the elastic element, so that the torsion spring 300 is sleeved on the rotating shaft 210, which helps to reduce the space occupied by the elastic element and the clamping part 200 as a whole, and thus helps to make the vehicle more compact.

[0045] Optionally, the first end of the clamping part 200 can be bent toward the side where the bearing area is located, and when the clamping part 200 is in the first position, the end face of the first end of the clamping part 200 can be parallel to the first end face of the battery cell A1.

[0046] The carrier disclosed in this application configures the first end of the clamping part 200 to be bent toward the side where the bearing area is located, and when the clamping part 200 is in the first position, the end face of the first end of the clamping part 200 is parallel to the first end face of the battery cell A1, so that the clamping part 200 contacts the circuit board A2 through surface contact when pressing the circuit board A2, thereby facilitating the protection of the circuit board A2.

[0047] Optionally, the second end of the clamping part 200 may have a groove 220, which can be used to engage with the actuating member 620 of the drive mechanism 600 described later. Specifically, when the clamping part 200 moves from the second position to the first position, the actuating member 620 can extend into the groove 220 and actuate the clamping part 200 until the elastic force of the elastic member driving the clamping part 200 is greater than the magnetic attraction force between the magnetic member 400 and the clamping part 200 (for example, the third position mentioned later). After that, the actuating member 620 can extend out of the groove 220, and the clamping part 200 can move to the first position under the action of the elastic force of the elastic member and remain in the first position. When the clamping part 200 moves from the first position to the second position, the actuating member 620 can extend into the dial groove 220 and actuate the clamping part 200 until the elastic force of the elastic member driving the clamping part 200 is less than the magnetic attraction force between the magnetic member 400 and the clamping part 200 (for example, the fourth position mentioned later). After that, the actuating member 620 can extend out of the dial groove 220, and the clamping part 200 can move to the second position under the action of the magnetic attraction force of the magnetic member 400 and remain in the second position.

[0048] The carrier disclosed in this application provides a groove 220 at the second end of the clamping part 200, so that the actuating member 620 of the drive mechanism 600 can extend into the groove 220 and cooperate with the clamping part 200, thereby improving the stability of the cooperation between the actuating member 620 and the clamping part 200.

[0049] Optionally, the vehicle may also include a mounting block 500, the vehicle body 100 may have a mounting groove 120, the mounting block 500 may be disposed in the mounting groove 120 and may be detachably connected to the vehicle body 100, and the clamping part 200 may be movably disposed on the mounting block 500.

[0050] The vehicle disclosed in this application embodiment has a mounting block 500 detachably disposed on the vehicle body 100, and a clamping part 200 disposed on the mounting block 500, so that the clamping part 200 can be installed on the mounting block 500 first and then as a whole installed on the vehicle body 100. This allows the vehicle to be assembled modularly first and then as a whole, thereby facilitating the assembly and disassembly of the vehicle.

[0051] To prevent the clamping part 200 from damaging the circuit board A2 when it is in the first position, the carrier body 100 may optionally have a limiting member. When the clamping part 200 is in the first position, the clamping part 200 may make limiting contact with the limiting member to restrict the clamping part 200 from continuing to press the circuit board A2 against the first end face of the battery cell A1.

[0052] It should be noted that when the clamping part 200 is in contact with the limiting member, the clamping part 200 can press the circuit board A2 just on the first end face of the battery cell A1. The clamping force of the clamping part 200 and the first end face of the battery cell A1 on the circuit board A2 is small and will not damage the circuit board A2.

[0053] The carrier disclosed in this application provides a limiting member on the carrier body 100, so that when the clamping part 200 is in the first position, the clamping part 200 can make limited contact with the limiting member to restrict the clamping part 200 from continuing to press the circuit board A2 against the first end face of the battery cell A1, thereby preventing the clamping part 200 from crushing the circuit board A2 when in the first position.

[0054] In some embodiments, a pressure sensor or a distance sensor may be provided on the circuit board A2. The pressure sensor can detect the clamping force between the clamping part 200 and the first end face of the battery cell A1 on the circuit board A2, and the distance sensor can detect the distance moved by the clamping part 200. The pressure value detected by the pressure sensor or the distance value detected by the distance sensor can be used as feedback information to confirm the position information of the circuit board A2, thereby more accurately confirming whether the circuit board A2 is pressed on the first end face of the battery cell A1.

[0055] This application also discloses a drive mechanism for cooperating with the vehicle disclosed in the above embodiments. The drive mechanism 600 includes a drive body 610 and an actuating member 620 connected to the drive body 610. The drive body 610 can drive the actuating member 620 to extend into the actuating slot 220, and drive the clamping portion 200 to rotate to a third position or a fourth position via the actuating member 620. The third and / or fourth positions are both located between the first and second positions. In the third position, the elastic force of the elastic member driving the clamping portion 200 is greater than the magnetic attraction force between the magnetic member 400 and the clamping portion 200. In the fourth position, the elastic force of the elastic member driving the clamping portion 200 is less than the magnetic attraction force between the magnetic member 400 and the clamping portion 200. The drive mechanism 600 and the vehicle are separate structures, with the drive mechanism 600 forming an offline drive mechanism relative to the vehicle.

[0056] Specifically, when the clamping part 200 moves from the second position to the first position, the actuating member 620 can extend into the dial groove 220 and actuate the clamping part 200 to the third position. At this time, the elastic force of the elastic member driving the clamping part 200 is greater than the magnetic attraction force between the magnetic member 400 and the clamping part 200. After that, the actuating member 620 can extend out of the dial groove 220, and the clamping part 200 can move to the first position under the action of the elastic force of the elastic member and remain in the first position. When the clamping part 200 moves from the first position to the second position, the actuating member 620 can extend into the dial groove 220 and actuate the clamping part 200 to the fourth position. At this time, the elastic force of the elastic member driving the clamping part 200 is less than the magnetic attraction force between the magnetic member 400 and the clamping part 200. After that, the actuating member 620 can extend out of the dial groove 220, and the clamping part 200 can move to the second position under the action of the magnetic attraction force of the magnetic member 400 and remain in the second position.

[0057] The drive mechanism 600 disclosed in this application cooperates with the vehicle disclosed in the above embodiments, so that the drive mechanism 600 forms an offline drive structure relative to the vehicle. The drive mechanism 600 does not need to be installed on the vehicle, which is beneficial to the compactness and lightweight design of the vehicle.

[0058] Optionally, the drive body 610 may include a base 611, a first transverse cylinder 612, and a second transverse cylinder 613. The first transverse cylinder 612 may be disposed on the base 611, the second transverse cylinder 613 may be disposed on the first transverse cylinder 612, and the actuating member 620 may be disposed on the second transverse cylinder 613. The first transverse cylinder 612 may drive the second transverse cylinder 613 to move the actuating member 620 along a first horizontal direction, and the second transverse cylinder 613 may drive the actuating member 620 along a second horizontal direction. The first horizontal direction may be perpendicular to the second horizontal direction. The first horizontal direction may be the direction in which the actuating member 620 extends into or out of the toggle slot 220.

[0059] Of course, the drive body 610 can also be other structures. For example, the drive body 610 can be a combination structure of a lead screw mechanism and a drive motor. The embodiments of this application do not impose specific limitations on the structure of the drive body 610.

[0060] The above embodiments of this utility model mainly describe the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. For the sake of brevity, they will not be described in detail here.

[0061] The embodiments of the present invention have been described above with reference to the accompanying drawings. However, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of the present invention.
