Description

Technical Field

[0001] This application relates to the field of battery installation technology, and in particular to a battery fixing mechanism and an electric vehicle. Background Technology

[0002] With the development of technology, the application of electric energy is becoming more and more widespread. Many electric energy devices have batteries. Batteries have the function of storing electrical energy and can quickly replenish the power of devices by replacing the batteries. However, many current battery fixing mechanisms are not convenient enough during the battery replacement process. The fixing device may bump the battery during the battery replacement process, thereby damaging the battery, or the battery may not be fixed firmly enough, causing the battery to shift. Summary of the Invention

[0003] This application provides a battery fixing mechanism and an electric vehicle to solve the problems of battery fixing mechanism easily damaging the battery during battery replacement and battery easily shifting.

[0004] This application provides a battery fixing mechanism, which includes a housing, a first slide rail, a limiting member, a receiving compartment, and a locking mechanism. The first slide rail is fixed to the bottom wall of the housing, and the limiting member is rotatably fixed to the inner wall of the housing. The receiving compartment is provided with a second slide rail, which is movable relative to the first slide rail. The receiving compartment is used to receive a battery, and the locking mechanism is used to lock the first slide rail and the second slide rail. When the receiving compartment has not reached a preset position, the battery is placed in the receiving compartment, and the locking mechanism is in an unlocked state. When the receiving compartment moves relative to the first slide rail, one end of the limiting member is pushed, and the limiting member rotates relative to the housing. When the receiving compartment reaches the preset position, along the height direction of the battery fixing mechanism, the other end of the limiting member abuts against the battery located in the receiving compartment, and the locking mechanism is in a locked state.

[0005] When the battery is placed, the locking mechanism is in the unlocked state, and the first and second slide rails can slide relative to each other. The receiving compartment adjusts its position as the second slide rail slides, moving to a position close to the opening of the outer shell, making it easy to place the battery in the receiving compartment. After the battery is placed in the receiving compartment, the receiving compartment slides relative to the first slide rail along the second slide rail. When the receiving compartment slides, the limiting member is pushed and rotates relative to the outer shell. When the receiving compartment reaches the preset position, the locking mechanism locks, and the receiving compartment can no longer slide relative to the first slide rail along the second slide rail. The limiting member presses the battery, restricting the battery from moving along the height direction of the battery fixing mechanism, thus fixing the battery. In the solution provided in this application, there are no other limiting components blocking the battery during the process of placing it into the receiving compartment, reducing the risk of battery bumps and improving the convenience of battery replacement.

[0006] In one possible implementation, the limiting member has a first elastic element, one end of which is connected to the inner wall of the housing, and the other end of which is connected to the limiting member.

[0007] The first elastic element connects the limiting element and the outer shell so that when the receiving compartment has not reached the preset position, the limiting element is in the preset position, which is convenient to push the limiting element when the receiving compartment slides. When the limiting element is pushed, the first elastic element deforms and the limiting element can rotate. When the limiting element is no longer pushed, the limiting element resets under the elastic force of the first elastic element, which is convenient to push it when the battery is placed next time.

[0008] In one possible implementation, the limiting member includes a connecting portion and a fixing portion, the connecting portion being disposed at both ends of the fixing portion, the connecting portion being used to connect with the inner wall of the housing, and the fixing portion being used to press the battery.

[0009] The fixing part extends along the width direction of the battery fixing mechanism to both sides of the receiving compartment. The connecting part is connected to both ends of the fixing part and is connected to the inner walls of both sides of the outer casing. The connecting part can rotate relative to the outer casing. When the connecting part rotates, it can drive the fixing part to rotate, thereby rotating the fixing part to a preset position to abut against the battery.

[0010] In one possible implementation, one end of the connecting portion has a contact portion, at least a portion of which has a cross-sectional area larger than that of the connecting portion.

[0011] One end of the connecting part is provided with a contact part, which is used to increase the contact area and facilitate the rotation of the limiting member. The contact part can be set as an arc shape, so that the limiting member rotates more smoothly when the contact part is pushed.

[0012] In one possible implementation, the receiving compartment has a stop block disposed on the outer side wall of the receiving compartment, and the stop block is able to contact the contact portion when the receiving compartment moves relative to the first slide rail.

[0013] The stop block is fixed to the outer wall of the receiving compartment. When the receiving compartment slides relative to the first slide rail along the second slide rail, the stop block can slide with the receiving compartment and push the limiting member to rotate. When the receiving compartment reaches the preset position, the stop block will also push the limiting member to the preset position, and the limiting member will abut against the battery to fix the battery.

[0014] In one possible implementation, the stop has a guide portion at an angle to the bottom wall of the receiving chamber, the guide portion being used to push the limiting member.

[0015] The part of the stop block that contacts the limiting member has a guide portion. There is an angle between the guide portion and the bottom wall of the receiving chamber. When the stop block moves with the receiving chamber and the guide portion contacts the limiting member, the limiting member can be pushed by the guide portion and slide along the guide portion, making the rotation of the limiting member more stable.

[0016] In one possible implementation, the battery fixing mechanism is provided with two blocks, which are disposed on both sides of the receiving compartment along the width direction of the receiving compartment, and the blocks are respectively disposed corresponding to the contact portion.

[0017] The blocks can be symmetrically arranged on both sides of the receiving compartment along the width direction of the battery fixing mechanism. When the battery is placed in the receiving compartment and the receiving compartment is moved to the preset position, the blocks on both sides can simultaneously push the limiting member to rotate, so that the force on the limiting member is more even when it rotates. When the receiving compartment reaches the preset position, the blocks on both sides can also simultaneously restrict the position of the limiting member, so that the limiting member is more stably in contact with the battery.

[0018] In one possible implementation, the receiving compartment has a limiting block that is movable relative to the receiving compartment, the limiting block being used to restrict the movement of the battery relative to the receiving compartment along the length direction of the receiving compartment.

[0019] The limiting block can be set on the bottom wall of the receiving compartment and can move relative to the receiving compartment. When the receiving compartment has not reached the preset position and the battery is put into the receiving compartment, the limiting block can retract relative to the receiving compartment to facilitate the battery being put into the receiving compartment. When the battery is put into the receiving compartment and the receiving compartment reaches the preset position, the limiting block can protrude relative to the receiving compartment to restrict the battery from moving along the length direction of the receiving compartment.

[0020] In one possible implementation, the limiting block has a second elastic element for resetting the limiting block.

[0021] The limiting block can be connected to the receiving compartment via a rotating shaft, and the limiting block can rotate relative to the receiving compartment. A second elastic element is disposed on the rotating shaft. The second elastic element can be a torsion spring, which is used to keep the second elastic element in a protruding state relative to the receiving compartment. When the battery is placed, the battery can press down on the limiting block to deform the second elastic element, and the limiting block retracts relative to the receiving compartment, making it easier to place the battery in the receiving compartment. When the battery is placed in the receiving compartment and the receiving compartment moves to a preset position, the limiting block resets under the action of the second elastic element, thereby restricting the movement of the battery along the length direction of the receiving compartment.

[0022] This application provides an electric vehicle, which includes a battery fixing mechanism, wherein the battery fixing mechanism is the battery fixing mechanism described in any of the above embodiments.

[0023] This application provides a battery fixing mechanism, which includes a housing, a first slide rail, a second slide rail, a limiting member, a receiving compartment, and a locking mechanism. The first slide rail is fixed to the bottom wall of the housing, and the limiting member is rotatably fixed to the inner wall of the housing. The receiving compartment is provided with a second slide rail and can move relative to the first slide rail. The locking mechanism is used to lock the first slide rail and the second slide rail. When the battery is installed, the locking mechanism is in an unlocked state, and the receiving compartment can move relative to the first slide rail and push one end of the limiting member. The limiting member rotates relative to the housing. When the receiving compartment reaches a preset position, along the height direction of the battery fixing mechanism, the other end of the limiting member abuts against the battery located in the receiving compartment, and the locking mechanism is in a locked state. The battery is not blocked by the limiting member during placement, reducing the risk of the battery being bumped or knocked.

For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

Furthermore, in the context, it should be understood that when it is mentioned that an element is connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected to the other element "upper" or "lower" through an intermediate element.

[0046] like Figure 1 and Figure 2As shown in the figure, this application embodiment provides a battery fixing mechanism, which includes a housing 1, a first slide rail 3, a limiting member 5, a receiving compartment 2, and a locking mechanism. The first slide rail 3 is fixed to the bottom wall of the housing 1, and the limiting member 5 is rotatably fixed to the inner wall of the housing 1. The receiving compartment 2 is provided with a second slide rail 4, which can move relative to the first slide rail 3. The receiving compartment 2 is used to receive a battery, and the locking mechanism is used to lock the first slide rail 3 and the second slide rail 4. When the receiving compartment 2 has not reached the preset position, the battery is placed in the receiving compartment 2, and the locking mechanism is in the unlocked state. When the receiving compartment 2 moves relative to the first slide rail 3, one end of the limiting member 5 is pushed, and the limiting member 5 rotates relative to the housing 1. When the receiving compartment 2 reaches the preset position, along the height direction of the battery fixing mechanism, the other end of the limiting member 5 abuts against the battery located in the receiving compartment 2, and the locking mechanism can be in the locked state.

[0047] When the battery is placed, the locking mechanism is in the unlocked state, and the first slide rail 3 and the second slide rail 4 can slide relative to each other. The receiving compartment 2 adjusts its position as the second slide rail 4 slides, and the receiving compartment 2 moves to a position close to the opening of the outer shell 1, making it easy to place the battery in the receiving compartment 2. After the battery is placed in the receiving compartment 2, the receiving compartment 2 slides relative to the first slide rail 3 along the second slide rail 4. When the receiving compartment 2 slides, the limiting member 5 is pushed and rotates relative to the outer shell 1. When the receiving compartment 2 reaches the preset position, the locking mechanism locks, and the receiving compartment 2 can no longer slide relative to the first slide rail 3 along the second slide rail 4. The limiting member 5 presses the battery, restricting the battery from moving along the height direction of the battery fixing mechanism, and playing a role in fixing the battery. In the solution provided in this application, there are no other limiting parts to block the battery during the process of placing it into the receiving compartment 2, which reduces the risk of battery bumps and improves the convenience of battery replacement.

[0048] like Figure 1 and Figure 2 As shown, in one possible implementation, the limiting member 5 has a first elastic member 6, one end of which is connected to the inner wall of the outer shell 1, and the other end is connected to the limiting member 5.

[0049] The first elastic member 6 connects the limiting member 5 and the outer shell 1 so that when the receiving compartment 2 has not reached the preset position, the limiting member 5 is in the preset position, which is convenient to push the limiting member 5 when the receiving compartment 2 slides. When the limiting member 5 is pushed, the first elastic member 6 deforms and the limiting member 5 can rotate. When the limiting member 5 is no longer pushed, the limiting member 5 is reset under the elastic force of the first elastic member 6, which is convenient to be pushed when the battery is placed next time.

[0050] like Figure 3As shown, in one possible implementation, the limiting member 5 includes a connecting part 52 and a fixing part 51. The connecting part 52 is respectively disposed at both ends of the fixing part 51. The connecting part 52 is used to connect with the inner wall of the outer casing 1, and the fixing part 51 is used to press the battery.

[0051] The fixing part 51 extends along the width direction of the battery fixing mechanism to both sides of the receiving compartment 2. The connecting part 52 is connected to both ends of the fixing part 51 respectively. The connecting part 52 is connected to the inner wall of both sides of the outer casing 1 respectively. The connecting part 52 can rotate relative to the outer casing 1. When the connecting part 52 rotates, it can drive the fixing part 51 to rotate, thereby rotating the fixing part 51 to a preset position to abut against the battery.

[0052] like Figure 3 As shown, in one possible implementation, one end of the connecting portion 52 has a contact portion 53, and at least a portion of the cross-sectional area of ​​the contact portion 53 is larger than the cross-sectional area of ​​the connecting portion 52.

[0053] One end of the connecting part 52 is provided with a contact part 53. The contact part 53 is used to increase the contact area, which makes it easier to push the limiting member 5 to rotate. The contact part 53 can be set to an arc shape. When the contact part 53 is pushed, the limiting member 5 rotates more smoothly.

[0054] like Figure 1 and Figure 2 As shown, in one possible implementation, the receiving compartment 2 has a stop 21, which is disposed on the outer side wall of the receiving compartment 2. When the receiving compartment 2 moves relative to the first slide rail 3, the stop 21 can contact the contact part 53.

[0055] The stop block 21 is fixed to the outer wall of the receiving compartment 2. When the receiving compartment 2 slides with the second slide rail 4 relative to the first slide rail 3, the stop block 21 can slide with the receiving compartment 2 and push the limiting member 5 to rotate. When the receiving compartment 2 reaches the preset position, the stop block 21 pushes the limiting member 5 to the preset position as well. The limiting member 5 abuts against the battery to fix the battery.

[0056] In one possible implementation, the stop 21 has a guide portion that forms an angle with the bottom wall of the receiving chamber 2, and the guide portion is used to push the limiting member 5.

[0057] The part of the stop block 21 that contacts the limiting member 5 has a guide portion. The guide portion has an angle with the bottom wall of the receiving chamber 2. When the stop block 21 moves with the receiving chamber 2 and the guide portion contacts the limiting member 5, the limiting member 5 can be pushed by the guide portion and slide along the guide portion, making the rotation of the limiting member 5 more stable.

[0058] In one possible implementation, the battery fixing mechanism is provided with two blocks 21, which are arranged on both sides of the receiving compartment 2 along the width direction of the receiving compartment 2, and the blocks 21 are respectively arranged corresponding to the contact part 53.

[0059] The blocks 21 can be symmetrically arranged on both sides of the receiving compartment 2 along the width direction of the battery fixing mechanism. When the battery is placed in the receiving compartment 2 and the receiving compartment 2 is moved to the preset position, the blocks 21 on both sides can simultaneously push the limiting member 5 to rotate, so that the force on the limiting member 5 when it rotates is more even. When the receiving compartment 2 reaches the preset position, the blocks 21 on both sides can also simultaneously restrict the position of the limiting member 5, so that the limiting member 5 is more stably in contact with the battery.

[0060] like Figure 1 and Figure 2 As shown, in one possible implementation, the receiving compartment 2 has a limiting block 7 that can move relative to the receiving compartment 2. The limiting block 7 is used to restrict the movement of the battery relative to the receiving compartment 2 along the length direction of the receiving compartment 2.

[0061] The limiting block 7 can be set on the bottom wall of the receiving compartment 2 and can move relative to the receiving compartment 2. When the receiving compartment 2 has not reached the preset position and the battery is put into the receiving compartment 2, the limiting block 7 can retract relative to the receiving compartment 2 to facilitate the battery being put into the receiving compartment 2. When the battery is put into the receiving compartment 2 and the receiving compartment 2 reaches the preset position, the limiting block 7 can protrude relative to the receiving compartment 2 to restrict the battery from moving along the length direction of the receiving compartment 2.

[0062] In one possible implementation, the limiting block 7 has a second elastic element for resetting the limiting block 7.

[0063] The limiting block 7 can be connected to the receiving compartment 2 via a rotating shaft, and the limiting block 7 can rotate relative to the receiving compartment 2. The second elastic element is provided on the rotating shaft. The second elastic element can be a torsion spring, which is used to keep the second elastic element in a protruding state relative to the receiving compartment 2. When the battery is placed, the battery can press down on the limiting block 7 to deform the second elastic element, and the limiting block 7 retracts relative to the receiving compartment 2, which facilitates the placement of the battery in the receiving compartment 2. When the battery is placed in the receiving compartment 2 and the receiving compartment 2 moves to a preset position, the limiting block 7 resets under the action of the second elastic element, thereby restricting the movement of the battery along the length direction of the receiving compartment 2.

[0064] This application provides an electric vehicle, which includes a battery fixing mechanism, wherein the battery fixing mechanism is the battery fixing mechanism described in any of the above embodiments.

[0065] This application provides a battery fixing mechanism and an electric vehicle. The battery fixing mechanism includes a housing 1, a receiving compartment 2, a first slide rail 3, a second slide rail 4, a limiting member 5, and a locking mechanism. The first slide rail 3 is fixed to the bottom wall of the housing 1, and the limiting member 5 is rotatably fixed to the inner wall of the housing 1. The receiving compartment 2 is provided with the second slide rail 4 and can move relative to the first slide rail 3. The locking mechanism is used to lock the first slide rail 3 and the second slide rail 4. When the battery is installed, the locking mechanism is in an unlocked state, and the receiving compartment 2 can move relative to the first slide rail 3 and push one end of the limiting member. The limiting member rotates relative to the housing 1.
