Description

Technical Field

[0001] This application relates to the field of motor motherboard storage technology, and in particular to motor motherboard storage fixtures. Background Technology

[0002] The motor motherboard is a core component of the motor drive system, typically consisting of PCB circuitry, electronic components (such as MCUs, MOSFETs, capacitors, etc.), and connection interfaces. The motherboard must be properly stored during manufacturing, testing, transportation, and storage.

[0003] Common storage fixtures employ mechanical positioning. By setting grooves, protrusions, or positioning pins on the fixture that match the shape of the motor motherboard, the motherboard can be precisely fixed in a specific position, ensuring that the entire motor motherboard will not shift after being placed in, thus facilitating the transportation and storage of the motor motherboard.

[0004] Regarding the aforementioned technologies, the inventors believe that after the motor motherboard is fixed, the electronic components installed on the motor motherboard are prone to collisions during transportation and storage, causing the electronic components to bend or fall off, resulting in circuit damage. Utility Model Content

[0005] The purpose of this application is to provide a motor motherboard storage fixture to improve the problem that after the motor motherboard is fixed, the electronic components installed on the motor motherboard are easily bumped during transportation and storage, causing the electronic components to bend or fall off, resulting in circuit damage.

[0006] The motor motherboard storage fixture provided in this application adopts the following technical solution:

[0007] The motor motherboard storage fixture includes a base frame support and a fixing plate for storing the entire board containing the motor motherboard. The fixing plate has a fixing groove corresponding to the entire board, and the base frame support has a locking groove corresponding to the fixing plate. A cover plate corresponding to the fixing plate is detachably connected to the top of the base frame support. A slide rod is slidably mounted on the cover plate toward the motor motherboard in the entire board. A pressure block is mounted on one end of the slide rod toward the motor motherboard. An elastic element is mounted on the outer side of the slide rod between the cover plate and the pressure block.

[0008] By adopting the above technical solution, the entire motor motherboard is fixed in the fixing slot, and then the fixing plate is fixed in the locking slot of the bottom frame bracket. The weight of the cover plate causes the pressure block on the cover plate to press against the highest capacitor on the motor motherboard, thus fixing the motor motherboard. At the same time, the sliding rod and spring buffer the clamping force on the capacitor of the motor motherboard. The cover plate and pressure block cover the motor motherboard, minimizing the risk of collision damage to the electronic components on the motor motherboard and affecting the circuit of the motor motherboard.

[0009] Optionally, a number of uprights are provided on the side of the cover plate facing the bottom frame support, and a positioning block corresponding to the uprights is provided above the bottom frame support. The positioning block has a positioning hole that fits with the upright.

[0010] By adopting the above technical solution, several uprights are set on the side of the cover plate facing the bottom frame support, so that the uprights are inserted into the positioning holes of the positioning block, which facilitates the positioning of the cover plate and prevents the pressure block from rubbing against the point on the motor main board due to the movement of the cover plate on the bottom frame support, which could cause the capacitor to tip over and be damaged.

[0011] Optionally, the bottom frame bracket is provided with fixing blocks at both ends, and the fixing blocks are provided with snap-fit ​​grooves on the side opposite to the snap-fit ​​groove. The cover plate is provided with connecting rods corresponding to the fixing blocks extending downward at both ends. The ends of the connecting rods are rotatably provided with snap-fit ​​joints corresponding to the snap-fit ​​grooves. An elastic element is provided between the end of the snap-fit ​​joint away from the fixing block and the connecting rod.

[0012] By adopting the above technical solution, the elastic element 2 pushes the snap-fit ​​connector to rotate, so that the end of the snap-fit ​​connector is snapped into the snap-fit ​​groove of the fixing block, thereby fixing the position of the cover plate and preventing the cover plate from detaching from the bottom frame bracket, causing the fixing plate and the motor main board on the fixing plate to detach and resulting in collision damage to the motor main board.

[0013] Optionally, the end of the snap-fit ​​connector facing the fixing block and the end of the fixing block facing the connecting rod are respectively inclined, and a pressing protrusion is provided on the side of the snap-fit ​​connector away from the elastic element 2.

[0014] By adopting the above technical solution, the end of the snap-fit ​​connector facing the fixing block and the end of the fixing block facing the connecting rod are set with corresponding inclined surfaces, which makes it easy for the snap-fit ​​connector to snap into the snap-fit ​​groove of the fixing block when the cover plate falls down; by applying force to the pressing protrusion, the elastic element 2 contracts, causing the snap-fit ​​connector to rotate away from the snap-fit ​​groove, which makes it easy to remove the cover plate from the bottom frame bracket and replace the entire motor main board.

[0015] Optionally, the thickness of the fixing plate is the same as the depth of the locking groove, and the bottom frame bracket is rotatably provided with locking blocks at both ends that abut against the fixing plate.

[0016] By adopting the above technical solution, the thickness of the fixing plate is consistent with the depth of the locking groove of the bottom frame bracket, so that the fixing plate is flush with the surface of the bottom frame bracket after being placed in the locking groove. The fixing plate is fixed by rotating the locking block against the upper surface of the fixing plate, preventing the fixing plate from shaking in the locking groove and causing damage to the high capacitors in the electronic components of the motor main board by colliding with the pressure block.

[0017] Optionally, the bottom frame bracket has loading and unloading grooves at both ends that communicate with the locking groove and correspond to the fixing plate. The depth of the loading and unloading groove is greater than the depth of the locking groove.

[0018] By adopting the above technical solution, loading and unloading grooves are provided at both ends of the bottom frame bracket, which are connected to the locking groove and correspond to the fixing plate. The depth of the loading and unloading groove is greater than the depth of the locking groove, which facilitates the quick assembly and disassembly of the fixing plate placed in the locking groove and reduces the possibility that the fixing plate cannot be removed.

[0019] Optionally, the fixing plate has a second loading and unloading groove on both sides of the fixing groove, which communicates with the first fixing groove and corresponds to the whole plate. The depth of the second loading and unloading groove is greater than the depth of the fixing groove.

[0020] By adopting the above technical solution, a second loading and unloading groove is provided on both sides of the fixing plate, which is connected to the first fixing groove and corresponds to the whole plate. The depth of the second loading and unloading groove is greater than the depth of the fixing groove, which facilitates the quick assembly and disassembly of the whole plate that is fixed in the first fixing groove of the fixing plate, and prevents the whole plate from being bent and damaged when the whole plate of the motor main board is removed.

[0021] Optionally, the fixing plate has several clearance grooves at the bottom of the fixing groove that correspond to the solder points of the motor main board.

[0022] By adopting the above technical solution, when the entire motor motherboard is clamped into the fixing groove of the fixing plate, the solder joints on the back of the motor motherboard are in the clearance groove, which prevents the electronic components from loosening and damaging the resistors when the solder joints are impacted when the motor motherboard is clamped into the fixing plate.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Secure the entire motor motherboard in the fixing slot, then secure the fixing plate in the locking slot of the bottom frame bracket. The pressure block on the cover plate abuts against the highest capacitor on the motor motherboard to press and fix the motor motherboard. At the same time, the sliding rod and spring buffer the clamping force on the capacitor of the motor motherboard. The cover plate and pressure block cover the motor motherboard to avoid collision damage to the electronic components on the motor motherboard and affect the circuit of the motor motherboard.

[0025] 2. The thickness of the fixing plate is consistent with the depth of the locking groove of the bottom frame bracket, so that the fixing plate is flush with the surface of the bottom frame bracket after being placed in the locking groove. The fixing plate is fixed by rotating the locking block against the upper surface of the fixing plate, which prevents the fixing plate from shaking in the locking groove and causing damage to the high capacitors in the electronic components of the motor main board by colliding with the pressure block.

[0026] 3. On both sides of the fixing plate located in the fixing groove, there are two loading and unloading grooves that communicate with the fixing groove and correspond to the whole plate. The depth of the loading and unloading groove is greater than the depth of the fixing groove, so as to facilitate the quick assembly and disassembly of the whole plate that is fixed in the fixing groove of the fixing plate and fixes the motor main board, and prevent the whole plate from bending and being damaged when the whole plate of the motor main board is removed.

[0031] The following is in conjunction with the appendix Figure 1 -Appendix Figure 3 This application will be described in further detail below.

[0032] Motor motherboard storage fixture, refer to Figure 1 and Figure 2The system includes a base frame support 1 and a fixing plate 2 for storing the entire plate 3 containing the motor main board 31. The base frame support 1 is made of rigid plastic, and the fixing plate 2 is made of metal plate. The fixing plate 2 has a fixing groove 21 corresponding to the entire plate 3, which secures the entire plate 3 containing the motor main board 31. The base frame support 1 has a corresponding engaging groove 11 for fixing the fixing plate 2. A rigid plastic cover plate 4 corresponding to the fixing plate 2 is detachably connected to the top of the base frame support 1. The cover plate 4 slides through a groove towards the motor main board 31 in the entire plate 3. The slide bar 42 is slidably connected to the slide bar 42. A pressure block 41 made of FR4 material is threadedly connected to the end of the slide bar 42 facing the motor main board 31. A spring 43, which is an elastic element, is installed on the outside of the slide bar 42 between the cover plate 4 and the pressure block 41. The pressure block 41 presses against the capacitor of the motor main board 31 on the fixing plate 2 by the weight of the cover plate 4, and presses and fixes the motor main board 31. At the same time, the slide bar 42 and the spring buffer the pressure force on the capacitor of the motor main board 31, so as to avoid damage to the electronic components on the motor main board 31 and affect the circuit of the motor main board 31.

[0033] Reference Figure 2 The thickness of the fixing plate 2 is consistent with the depth of the locking groove 11 of the bottom frame bracket 1, so that the fixing plate 2 is flush with the surface of the bottom frame bracket 1 after being placed in the locking groove 11. Plastic locking blocks 14 are rotatably connected to both ends of the bottom frame bracket 1 via rotating shafts. By rotating the locking blocks 14, they abut against the upper surface of the fixing plate 2, fixing the fixing plate 2 and preventing the fixing plate 2 from shaking in the locking groove 11, which could cause the high capacitors in the electronic components of the motor main board 31 to collide with the pressure block 41 and cause damage. Several clearance grooves 23 corresponding to the solder joints of the motor main board 31 are opened at the bottom of the fixing groove 21 on the fixing plate 2, so as to prevent the electronic components from loosening when the solder joints of the motor main board 31 are impacted when it is inserted into the fixing plate 2 along with the whole plate 3, which could damage the resistors.

[0034] Reference Figure 2 At both ends of the bottom frame bracket 1, there are loading and unloading grooves 15 that communicate with the locking groove 11 and correspond to the fixing plate 2. The depth of the loading and unloading groove 15 is greater than the depth of the locking groove 11, which facilitates the assembly and disassembly of the fixing plate 2 placed in the locking groove 11. On both sides of the fixing plate 2 located in the fixing groove 21, there are loading and unloading grooves 22 that communicate with the fixing groove 21 and correspond to the whole plate 3. The depth of the loading and unloading groove 22 is greater than the depth of the fixing groove 21, which facilitates the assembly and disassembly of the whole plate 3 that fixes the motor main board 31 in the fixing groove 21 of the fixing plate 2.

[0035] Reference Figure 2 and Figure 3Several metal uprights 44 are provided on the side of the cover plate 4 facing the bottom frame support 1. A positioning block 12 corresponding to the uprights 44 is fixed on the bottom frame support 1 with screws. The positioning block 12 has a positioning hole 121 that fits with the uprights 44, which facilitates the positioning of the cover plate 4 and prevents the cover plate 4 from moving on the bottom frame support 1, causing friction between the pressure block 41 and the point on the motor main board 31, which could cause the capacitor to tip over and be damaged.

[0036] Reference Figure 2 Fixing blocks 13 are fixed to both ends of the bottom frame bracket 1 with screws. A snap-fit ​​groove 131 is formed on the side of the fixing block 13 opposite to the snap-fit ​​groove 11. Connecting rods 45, corresponding to the fixing blocks 13, extend downwards from both ends of the cover plate 4 and are fixed with screws. A snap-fit ​​connector 46, corresponding to the snap-fit ​​groove 131, is rotatably connected to the end of the connecting rod 45 away from the cover plate 4 via a rotating shaft. A spring, acting as a second elastic element 47, is snap-fitted between the end of the snap-fit ​​connector 46 away from the fixing block 13 and the connecting rod 45. The second elastic element 47 pushes the snap-fit ​​connector 46 into the snap-fit ​​groove 131 of the fixing block 13, fixing the position of the cover plate 4 and preventing the cover plate 4 from detaching from the bottom frame bracket 1. The fixing plate 2 and the motor main board 31 on the fixing plate 2 are detached, causing collision damage to the motor main board 31. The end of the snap connector 46 facing the fixing block 13 and the end of the fixing block 13 facing the connecting rod 45 are respectively set with corresponding inclined surfaces, so that the snap connector 46 can be snapped into the snap groove 131 of the fixing block 13 when the cover plate 4 falls. An integrally formed pressing protrusion 461 is provided on the side of the snap connector 46 away from the elastic element 47. By applying force to the pressing protrusion 461, the elastic element 47 is contracted, and the snap connector 46 rotates away from the snap groove 131, so that the cover plate 4 can be removed from the bottom frame bracket 1 to replace the entire plate 3 of the motor main board 31.

[0037] The implementation principle of this application embodiment is as follows:

[0038] In actual operation, after the main board 3 of the motor motherboard 31 is fixed and positioned with the fixing plate 2 and fixed with the bottom frame bracket 1, the fixing plate 2 is fixed by rotating the locking block 14. The upright 44 of the cover plate 4 is inserted into the positioning hole 121 of the positioning block 12. The cover plate 4 is positioned and fixed by locking the locking connector 46 into the locking groove 131 of the fixing block 13. The pressure block 41 on the cover plate 4 abuts against the highest capacitor on the motor motherboard 31 to press and fix the motor motherboard 31. At the same time, the sliding rod 42 and the spring buffer the clamping force on the capacitor of the motor motherboard 31. The cover plate 4 and the pressure block 41 cover the motor motherboard 31 to avoid collision damage to the electronic components on the motor motherboard 31 and affect the circuit of the motor motherboard 31.
