[0002] New energy vehicles refer to vehicles that use non-traditional energy as the power source or adopt new energy technologies (such as plug-in hybrid, range-extended hybrid, etc.). The batteries on new energy vehicles are supported by battery trays so that the batteries are placed at corresponding positions on the vehicle. The battery tray generally consists of a tray bottom plate and side guards surrounding the edge of the tray bottom plate. The tray bottom plate and the side guards are generally welded into one body. When the battery tray is connected and fixed to the battery, multiple groups of screws are often required to fix the new energy battery pack to ensure that the battery tray and the battery are tightly connected during driving. The existing automatic screw fastening mechanism presses and fixes the tray through a cylinder claw, and then locks the screws of the battery pack to the tray. The cylinder claw structure requires workers to adjust the machine to adapt the pressing height and pressing force for battery trays with different heights, which increases the difficulty of use. Moreover, the surface of the battery tray is easily damaged when being pressed, and it also has a certain impact on the yield of the product appearance. Summary of the Utility Model

Three side edges of the base are all provided with edge guards, and each edge guard is provided with an installation opening. The three edge guards cooperate to form a tray entry channel. The rotating end of the rotating motor is in threaded cooperation with an adjusting block, and the adjusting block is slidably matched with the base. The adjusting block is snap-connected with three pressing components. Each pressing component includes a first connecting rod, a transmission elastic member, and a pressing block. One end of the first connecting rod is snap-connected with the adjusting block, the other end of the first connecting rod is fixedly connected with the transmission elastic member, the pressing block is rotatably connected to the corresponding installation opening, the first end of the pressing block is fixedly connected with the transmission elastic member, and the second end of the pressing block presses and limits the tray.
[0005] Furthermore, the two groups of the retaining edges parallel to the entry direction of the tray are respectively provided with multiple groups of guide holes, and each of the guide holes is slidably connected with a centering piece, and the centering piece includes a rotating wheel, a sliding column and a centering elastic piece. The rotating wheel is rotatably connected to one end of the sliding column, and the sliding column is slidably matched with the corresponding guide hole. One end of the centering elastic piece is fixedly connected to the bottom surface of the sliding column, and the other end of the centering elastic piece is pushed and matched with the guide hole.
[0006] Furthermore, a sliding cavity is formed at the bottom of the base for the adjustment block to move up and down, and a sliding groove is formed on the side wall of the sliding cavity for slidingly cooperating with the adjustment block. The bottom of the base is also provided with three movable grooves for the corresponding up and down movement of the first connecting rod, and the three movable grooves are all connected to the sliding cavity.
[0007] Furthermore, the side wall of the adjustment block is formed with three groups of corresponding slots that are engaged with the corresponding first connecting rods, and the side wall of the adjustment block is also formed with a slider that slidably cooperates with the slide slot, and the slider is arranged between two groups of the slots. The middle part of the adjustment block is provided with an adjustment hole that is threadedly engaged with the rotating end of the rotating motor, and the upper surface of the base is also provided with a positioning hole, and the adjustment block is provided with a positioning rod that passes through the positioning hole and is positioned with the tray guide.
[0008] Furthermore, each of the mounting ports is provided with two groups of mounting columns, each of the mounting columns is formed with a mounting hole, and the pressing block is rotatably connected to the mounting hole.
[0009] Furthermore, a connection block is formed between the two groups of the installation columns, a detection space is formed between the connection block and the base, and an in-place detection member is provided in the detection space.

With the cooperation of multiple groups of centering members provided on both sides, when the tray enters the base, it is elastically pushed by the centering members and moves to the middle position of the base. The external screw automatic fastening mechanism can quickly position, improving the screw fastening efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Such as Figures 1 to 10As shown in the figure, in this embodiment, the utility model includes a base 1 for placing a tray, a rotating motor 2 provided at the bottom of the base 1. Three side edges of the base 1 are each provided with a baffle 11, and each baffle 11 is provided with an installation opening 12. The three baffles 11 cooperate to form a tray entry channel. The rotating end of the rotating motor 2 is in threaded cooperation with an adjusting block 3, and the adjusting block 3 is slidably matched with the base 1. The adjusting block 3 is snap-connected with three groups of pressing components 4. Each pressing component 4 includes a first connecting rod 41, a transmission elastic member 42, and a pressing block 43. One end of the first connecting rod 41 is snap-connected with the adjusting block 3, the other end of the first connecting rod 41 is fixedly connected with the transmission elastic member 42, the pressing block 43 is rotatably connected to the corresponding installation opening 12, the first end of the pressing block 43 is fixedly connected with the transmission elastic member 42, and the second end of the pressing block 43 presses and limits the tray. The transmission elastic member 42 is a compression spring. A plurality of countersunk holes are provided on the surface of the base 1. After the tray is placed, it is convenient for the staff to insert positioning pins or limit posts for fixing or adjusting the position of the tray. The pressing component 4 uses the transmission elastic member 42 to transmit the momentum of the up and down movement of the adjusting block 3. When the rotating motor 2 outputs torque to make the adjusting block 3 move upward, the first connecting rod 41 drives the transmission elastic member 42 to push the first end of the pressing block 43 upward. The middle part of the pressing block 43 rotates around the installation opening 12, so that the second end of the pressing block 43 presses and limits the tray. After the pressing block 43 presses the tray, it stops rotating. If the rotating motor 2 continues to move upward at this time, the transmission elastic member 42 is compressed, and the upward thrust is converted into spring force and the tray is pressed by the spring force, effectively avoiding excessive torque output by the adjusting motor, so that the downward displacement of the pressing block 43 is too large, resulting in damage to the tray shell, and realizing the floating pressing and limiting of the tray. One group of adjusting blocks 3 drives the pressing components 4 in three directions to move simultaneously, with a compact structure and convenient use, effectively improving the convenience of use. The three groups of baffles 11 provided on the base 1 form an entry channel. The tray is placed on the base 1 along the preset channel. With the elastic pushing of the multiple centering members 14 provided on both sides, the tray moves to the middle position of the base 1, and the external screw automatic fastening mechanism can quickly position and improve the screw fastening efficiency.
[0025] In this embodiment, two sets of the edge guards 11 parallel to the tray entry direction are respectively provided with multiple sets of guiding holes 13. Each guiding hole 13 is slidably connected with a centering member 14. The centering member 14 includes a rotating wheel 141, a sliding column 142 and a centering elastic member 143. One end of the rotating wheel 141 is rotatably connected to the sliding column 142. The sliding column 142 is slidably matched with the corresponding guiding hole 13. One end of the centering elastic member 143 is fixedly connected to the bottom surface of the sliding column 142. The other end of the centering elastic member 143 is in a pushing fit with the guiding hole 13. The centering elastic member 143 is a compression spring. The rotating wheel 141 is made of rubber material, having good wear resistance and elasticity. When rolling and rubbing against the side of the tray, it can effectively avoid damage caused by hard contact. The lengths and compression amounts of the centering elastic members 143 of the multiple sets of centering members 14 on both sides are the same, providing the same thrust force. Under the elastic force of the centering elastic member 143 after the tray enters, it moves to the middle position of the base 1, facilitating the rapid positioning of the external screw automatic fastening mechanism and improving the screw fastening efficiency.
[0026] In this embodiment, a sliding cavity 15 for the up-and-down movement of the adjusting block 3 is formed at the bottom of the base 1. A sliding groove for slidably matching with the adjusting block 3 is formed on the side wall of the sliding cavity 15. Three moving grooves 18 for the up-and-down movement of the first connecting rod 41 are further provided at the bottom of the base 1. All three moving grooves 18 are communicated with the sliding cavity 15. The sliding cavity 15 is cylindrical. The sliding groove is arranged between two adjacent moving grooves 18, guiding and coordinating the up-and-down movement of the adjusting block 3. At the same time, the adjusting block 3 makes an up-and-down reciprocating movement under the thread drive of the rotating motor 2, avoiding the situation that the adjusting block 3 rotates due to excessive friction during thread fitting. The moving groove 18 is a square groove. The width and height of the moving groove 18 are greater than the width and height of the first connecting rod 41. Different-width or different-height first connecting rods 41 can be replaced according to the tray to be limited and pressed, ensuring that the output pressure is sufficient to press the tray while not damaging the tray surface.
[0027] In this embodiment, three groups of card slots 31 corresponding to and engagingly connected with the respective first link rods 41 are formed on the side wall of the adjusting block 3. A sliding block 32 that is slidably engaged with the sliding groove is further formed on the side wall of the adjusting block 3. The sliding block 32 is disposed between two groups of the card slots 31. An adjusting hole that is in threaded engagement with the rotating end of the rotating motor 2 is provided in the middle of the adjusting block 3. A positioning hole 17 is further provided on the upper surface of the base 1. The adjusting block 3 is provided with a positioning rod 33 that passes through the positioning hole 17 of the base 1 and guides and positions the tray. The three groups of card slots 31 are arranged at equal intervals and are parallel to the three side edges 11 of the base 1. Threads are provided in the adjusting hole. Since openings for ventilation or observing the internal situation are provided in the middle of the battery tray, during the upward movement of the adjusting block 3, the positioning rod 33 structure of the adjusting block 3 passes through the positioning hole 17 of the base 1, inserts into the tray, and guides and positions it, restricting the movement of the tray in the XY two directions. The structure is simple and convenient to use.
[0028] In this embodiment, two groups of mounting posts 121 are provided in each mounting opening 12. Each mounting post 121 is formed with a mounting hole 122. The pressing block 43 is rotatably connected to the mounting hole 122. The pressing block 43 is provided with a rotating column, and the rotating column passes through the mounting hole 122 to rotatably connect the pressing block 43 between the two groups of mounting posts 121.
[0029] In this embodiment, a connecting block 123 is formed between the two groups of mounting posts 121. A detection space is formed between the connecting block 123 and the base 1. A position detection member 5 is provided in the detection space. The position detection members 5 located on both sides are used to detect the entry of the tray and the distances between the two side edges of the tray and the corresponding side edges 11. The position detection member 5 located at the rear is used to detect the entry of the tray. When the distances between the two side edges of the tray and the corresponding two side edges 11 are the same, it is determined that the centering operation is completed. If the distances are different, an external reminder member is used to remind the staff to manually adjust. The reminder member can be a buzzer, a signal lamp, or a display screen. After the position detection member 5 located at the rear detects that the tray is in place, it feeds back to the automatic screw tightening device to start positioning and complete the screw locking and tightening.
[0030] In this embodiment, a connecting cylinder 431 fixedly connected to the transmission elastic member 42 is provided at one end of the pressing block 43, a first guide pin 432 guiding and cooperating with the transmission elastic member 42 is provided in the middle of the connecting cylinder 431, and a clearance groove 433 for the transmission elastic member 42 to bend forward and backward is provided on the connecting cylinder 431. A groove is formed at the other end of the pressing block 43, and a gasket 44 is provided in the groove to be tightly matched with the tray. The connecting cylinder 431 and the first guide pin 432 make the spring compressed along the direction of the first guide pin 432 when compressed, so as to ensure that the transmission elastic member 42 can be effectively To store the pushing force, the width of the give way groove 433 is greater than the outer diameter of the transmission elastic member 42, which has a guiding effect on the transmission elastic member 42. When the pressure plate rotates, the connecting tube 431 forms a certain angle with the vertical line. At this time, the transmission elastic member 42 at both ends is respectively fixed on the first connecting rod 41 and the pressure block 43, and a partial bend is formed at one end close to the pressure block 43. The bent part eliminates interference through the give way groove 43, avoiding the difficulty of free rotation of the pressure block 43 due to interference between the bent part and the connecting tube 431. The gasket 44 is made of rubber and has good elasticity and friction, which effectively avoids the pressure block 43 from pressing down and damaging the tray.
[0031] In this embodiment, a clamping block 423 is formed at one end of the first connecting rod 41 that cooperates with the adjusting block 3, and a fixing cylinder 411 that cooperates with the transmission elastic member 42 is formed at the other end of the first connecting rod 41. A second elastic pin 412 that cooperates with the transmission elastic member 42 for guiding is provided in the middle of the fixing cylinder 411, and the clamping block 423 is used for quick disassembly and installation. The connecting cylinder 431 and the first guide pin make the spring compressed along the direction of the second guide pin when compressed, so as to ensure that the transmission elastic member 42 can effectively store the pushing force and have a guiding effect on the transmission elastic member 42.
[0032] The working principle of this utility model:
[0033] Before the tray is placed, the adjusting block 3 is located at the lower part of the sliding cavity 15, the three groups of pressing blocks 43 are in the open state, the centering members 14 on both sides are in the pushed-out state. The tray is placed into the base 1 along the tray entry channel. The rollers of the centering members 14 on both sides contact and press the centering elastic members 143 on the side of the tray. Multiple groups of centering elastic members 143 provide a pushing force towards the middle of the base 1 along one side of the edge stop 11, so that the tray moves to the middle position of the base 1, facilitating the positioning of the external screw fastening mechanism. The in-place detection members 5 on both sides are used to detect the entry of the tray and the distance between the two sides of the tray and the corresponding edge stops 11. When the distances between the two sides of the tray and the corresponding two edge stops 11 are the same, it is determined that the centering operation is completed. If the distances are different, an external reminder member is used to remind the staff to manually adjust. The in-place detection member 5 at the rear is used to detect the entry of the tray. After the tray is in place, the rotation motor 2 outputs torque to make the adjusting member move upward. The adjusting member moves vertically along the sliding cavity 15, driving the three groups of first connecting rods 41 to rise and push one end of the pressing block 43 and the gasket 44 to tightly press the tray. The adjusting member continues to move upward, and the transmission elastic member 42 is compressed and stores the upward thrust. At the same time, the positioning rod 33 passes through the positioning hole 17 to limit the tray and prevent it from sliding.
[0034] Although the embodiments of the present invention are described with actual solutions, they do not constitute a limitation to the meaning of the present invention. For those skilled in the art, modifications to its implementation solutions according to this specification and combinations with other solutions are obvious.
