[0040] Embodiment 1

[0041] See also Figures 1 to 6 As shown, the limiting device 101 provided in the present application includes a driving mechanism and a pressure mechanism 102; the driving mechanism and the pressure mechanism 102 are connected, and a guide path is arranged between the driving mechanism and the pressure mechanism 102 to enable the driving mechanism and the pressure mechanism 102 to be linked; the guide path has a first component in a first direction and a second component in a second direction, so that the driving mechanism that reciprocates along the first direction can drive the pressure mechanism 102 to reciprocate in the second direction.

[0042] Specifically, if Figure 6 As shown, the limiting device 101 provided in the present application can be used on a carrier tray carrying batteries, and three linked limiting devices 101 are arranged on the carrier tray. External force only needs to act on one limiting device 101 to drive the three limiting devices 101 to act synchronously, thereby achieving synchronous pressure and positioning of the long side of the battery. The same limiting device 101 or a fixed limiting clamp can be arranged at the opposite long side of the battery to clamp and fix the battery from both sides.

[0043] The reason why the present application can realize the linkage of the three limit devices 101 is that the present application sets the direction of the external force and the direction of the pressure applied by the limit device 101 as two directions. As shown in the figure, Figure 6 The three limiting devices 101 are arranged at intervals along the length direction of the battery to apply pressure to the long side of the battery. The pressure direction of the limiting device 101 is the width direction of the battery. Since the arrangement direction of the three limiting devices 101 is the same as the movement direction of their respective driving mechanisms, the driving mechanisms of the three limiting devices 101 are connected. Only an external force needs to be applied to the driving mechanism of one limiting device 101 to drive the pressure mechanisms 102 of the three limiting devices 101 to synchronously reciprocate in the pressure direction, so that the pressure mechanisms 102 can pressurize the battery to position or release it.

[0044] The above technical effect can be achieved because the guide path is set between the driving mechanism and the pressure mechanism 102. Since the guide path has a first component in the first direction and a second component in the second direction, when the driving mechanism reciprocates along the first direction, the guide path can guide the movement of the pressure mechanism 102 so that the pressure mechanism 102 can only reciprocate in the second direction, thereby realizing the conversion of the movement direction.

[0045] The present application can realize linkage of multiple limiting devices 101 in the first direction, and the number of limiting devices 101 can be assembled according to the length of the battery. Only one driving device needs to be set to apply force to the limiting device 101 from the first direction, so that the pressure mechanisms 102 of the multiple limiting devices 101 move synchronously, thereby realizing pressure positioning or release of the battery, which can reduce the volume of the device and reduce the cost of the device.

[0046] In an optional solution of this embodiment, one of the driving mechanism and the pressure mechanism 102 is provided with a first guide channel 103 , and the other is provided with a guide sliding member 104 . The first guide channel 103 forms a guide path, and the guide sliding member 104 is slidably installed in the first guide channel 103 .

[0047] In this embodiment, if Figure 2 As shown, the pressure mechanism 102 shown in the figure is provided with a first guide channel 103, which is specifically a guide hole, and the driving mechanism is provided with a guide sliding member 104, which is specifically a cylindrical rod, and the guide sliding member 104 is placed in the guide hole and can reciprocate along the extension direction of the guide hole. When the guide sliding member 104 moves along the extension direction of the guide hole, the formed path has a motion component in the first direction and a motion component in the second direction, so that the pressure mechanism 102 can reciprocate in the second direction.

[0048] More specifically, if Figure 5As shown, the first guide channel 103 includes an initial portion 105, a transition portion 106 and a termination portion 107 which are connected in sequence; the initial portion 105 forms a first guide path, and the extension direction of the first guide path is the first direction; the transition portion 106 forms a second guide path, and the extension direction of the second guide path has a preset angle with the first direction; the termination portion 107 forms a third guide path, and the extension direction of the third guide path is the first direction.

[0049] In this embodiment, when the guide sliding member 104 is within the range of the initial portion 105, the pressure mechanism 102 is located closer to the battery and can remain at this position, thereby achieving reliable clamping of the battery. When the guide sliding member 104 moves to the transition portion 106 and moves along the extension direction of the transition portion 106, the second guide path formed has a movement component in the first direction and a movement component in the second direction, so that the pressure mechanism 102 can gradually move away from the battery. When the guide sliding member 104 moves to the termination portion 107, the pressure mechanism 102 is located at the farthest position from the battery and can remain at this position, thereby achieving release of the battery.

[0050] Further, the width of the initial portion 105 and the terminal portion 107 is greater than 1.5 times the diameter of the guide sliding member 104 to accommodate the guide sliding member 104 .

[0051] In an optional solution of this embodiment, a locking protrusion 108 is provided between the initial portion 105 and the transition portion 106 , and / or a locking protrusion 108 is provided between the transition portion 106 and the termination portion 107 .

[0052] In this embodiment, when the pressure mechanism 102 is in a state of clamping the battery, the position of the pressure mechanism 102 must remain stationary to achieve reliable clamping of the battery. Therefore, a clamping protrusion 108 is provided between the initial portion 105 and the transition portion 106 to ensure that the pressure mechanism 102 can remain in the clamping position when no external force is applied. Only when the driving force acting on the guide sliding member 104 is large enough can the guide sliding member 104 pass over the clamping protrusion 108. In this way, when the limiting device 101 is applied to a carrier tray, during the circulation of the carrier tray, there is no need to set a driving mechanism to maintain the clamping state of the battery.

[0053] Similarly, before clamping the battery or when removing the clamped battery, the pressure mechanism 102 needs to be distanced from the battery to leave a gripping space for the robot holding the battery, and the pressure mechanism 102 needs to be at a position away from the battery and remain motionless. Therefore, a positioning protrusion 108 is provided between the transition portion 106 and the termination portion 107 to ensure that the pressure mechanism 102 can remain at a position away from the battery when no external force is applied. Only when the driving force acting on the guide slide 104 is large enough can the guide slide 104 pass over the positioning protrusion 108.

[0054] Embodiment 2

[0055] The limiting device in the second embodiment is an improvement on the above embodiment, and the technical contents disclosed in the above embodiment will not be described repeatedly, and the contents disclosed in the above embodiment also belong to the contents disclosed in the second embodiment.

[0056] In an optional solution of this embodiment, the limiting device 101 further includes a guide seat 109; the guide seat 109 is provided with a second guide channel 110, and the guiding direction of the second guide channel 110 is the second direction; the pressure mechanism 102 is slidably mounted on the second guide channel 110. When the guide sliding member 104 reciprocates along the first guide channel 103, it can push the pressure mechanism 102 to move, and the second guide channel 110 provided by the guide seat 109 can guide the movement of the pressure mechanism 102, so that the pressure mechanism 102 can only reciprocate along the second direction, thereby clamping or releasing the battery.

[0057] In an optional solution of this embodiment, the pressure mechanism 102 includes a sliding block 111, an elastic member 112 and a pressure block 113; the sliding block 111 is slidably installed in the second guide channel 110, and the elastic member 112 is installed between the sliding block 111 and the pressure block 113; the sliding block 111 is provided with a first guide channel 103.

[0058] In this embodiment, if Figure 2 As shown, the guide seat 109 includes a base and an upper cover. The base is provided with a first guide groove, and the sliding block 111 is placed in the first guide groove. The upper cover is buckled at the notch of the base and is surrounded by the first guide groove to form a second guide channel 110, and the sliding block 111 is confined in the second guide channel 110. When the guide sliding member 104 reciprocates along the first guide channel 103, the guide sliding member 104 can push the sliding block 111, the elastic member 112 and the pressure block 113 to reciprocate along the second direction. The elastic member 112 includes at least one spring. When the sliding block 111 drives the pressure block 113 to clamp the battery, the spring between the sliding block 111 and the pressure block 113 can be compressed, and the elastic force acting on the pressure block 113 enables the pressure block 113 to abut against the surface of the battery to clamp the battery.

[0059] In an optional solution of this embodiment, the pressure mechanism 102 further includes at least one guide rod 114 , and the guide rod 114 is slidably installed between the sliding block 111 and the pressure block 113 .

[0060] In this embodiment, if only a spring is provided between the sliding block 111 and the pressure block 113, when the spring is compressed, the spring is easily skewed, so that the pressure block 113 cannot fit with the surface of the battery, thereby affecting the clamping effect on the battery. A guide rod 114 is also provided between the sliding block 111 and the pressure block 113. When the spring is compressed, the guide rod 114 can guide the relative movement of the sliding block 111 and the pressure block 113 so that the pressure block 113 fits with the battery surface. Figures 2 to 4 Two springs are shown in the figure, and the number of guide rods 114 is correspondingly two.

[0061] In an optional solution of this embodiment, the driving mechanism includes a driving rod 115; the length direction of the driving rod 115 is the first direction, and the driving rod 115 can reciprocate along the first direction; the driving rod 115 is provided with a guide sliding member 104. Specifically, both ends of the driving rod 115 are provided with connecting holes, and when multiple limiting devices 101 are linked, the multiple limiting devices 101 are connected in sequence along the first direction, and the driving rods 115 of adjacent limiting devices 101 can be connected to the connecting holes of two driving rods 115 by connecting blocks and screws, thereby driving the pressure mechanisms 102 of the multiple limiting devices 101 to move synchronously.

[0062] Furthermore, in order to guide the movement of the driving rod 115 , the guide seat 109 is provided with a third guide channel 116 , and the guiding direction of the third guide channel 116 is the first direction; the driving rod 115 is slidably installed in the third guide channel 116 ; the third guide channel 116 is connected to the second guide channel 110 .

[0063] In this embodiment, if Figure 2 As shown, the base of the guide seat 109 is also provided with a second guide groove connected with the first guide groove, the second guide groove is located below the first guide groove, the second guide groove has the groove bottom of the first guide groove as the upper edge, and the groove bottom of the second guide groove extends downward. The sliding block 111 located in the first guide groove can close the groove edge of the second guide groove, thereby forming a third guide channel 116, and the driving rod 115 is confined in the third guide channel 116. When the driving rod 115 reciprocates along the third guide channel 116, it can drive the guide sliding member 104 to reciprocate in the first guide channel 103.
