Technical Field

[0001] The present invention relates to the technical field of module installation, and in particular to a quick-release device of an electronic module and a disassembly method thereof. Background Art

[0002] Electronic modules on vehicles often require quick installation and removal, and they also need to meet harsh environmental requirements such as transportation vibration. In a transportation vibration environment, unreliable installation of electronic modules may cause the electronic components of the module to fail, affecting the function of the electronic module itself.

[0003] The operation and use space of electronic modules on vehicles is small, and at the same time, they need to meet the requirements of the transportation vibration environment. The design of electronic modules needs to meet the requirements of small size, quick and convenient disassembly and assembly, and firm and reliable installation. Existing electronic module quick installation mechanisms usually need to be equipped with complex structural frames, which take up too much installation space. Other simple quick installation mechanisms (such as back clips) cannot meet the installation reliability requirements.

[0004] Therefore, it is necessary to provide a quick-install electronic module to achieve quick and convenient disassembly and assembly, while meeting the requirements of firm and reliable installation and being suitable for the vibration environment of the vehicle and vehicle driving. Summary of the invention

[0005] In view of the above analysis, the present invention aims to provide a quick-release device for an electronic module and a method for disassembling and assembling the same, so as to solve the problems of inconvenient installation and unreliable fixation of existing vehicle-mounted electronic modules.

[0010] Furthermore, the seat plate is arranged perpendicular to the direction of the guide strip; when the guide block slides into the guide groove and the limiting block contacts the seat plate, the locking structure limits the guide block.

[0011] Furthermore, the lock structure includes: a lock and a compression spring; the lock is fixedly installed above the compression spring and protrudes from the lower surface of the guide groove; the upper end of the lock is a trapezoidal locking block; the trapezoidal locking block is used to limit the guide block from sliding in one direction relative to the lock and reverse locking.

[0012] Furthermore, the upper surface of the trapezoidal locking block is a first inclined surface; the bottom end of the first inclined surface is flush with the lower surface of the guide groove; the upper end of the first inclined surface protrudes from the lower surface of the guide groove; and the guide block can slide along the first inclined surface from the bottom end to the upper end.

[0013] Furthermore, the locking structure also includes: a mounting block; the mounting block is fixedly connected to the mounting plate by bolts or welding; the compression spring and the locking buckle are fixedly mounted on the mounting block.

[0014] Furthermore, the unlocking assembly is used to press down the lock buckle to release the lock of the guide block by the lock buckle.

[0020] 2) The quick-release device of the electronic module of the present invention has an upper guide block and a lower guide block both of which are L-shaped structures and are inserted into the guide grooves on the sides of the guide strips. The left-right sliding and up-and-down displacement of the module housing relative to the mounting plate are limited by the cooperation of the guide strips and the guide blocks. The front-and-back displacement of the module housing is limited by the cooperation of the limit block and the seat plate and the locking effect of the locking assembly.

[0039] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0040] Example 1

[0041] A specific embodiment of the present invention discloses a quick-release device for an electronic module, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, it includes: a module housing 1, a mounting plate 9, a guide block and a limit block 5 arranged at the bottom of the module housing 1, a guide strip 10 and a seat plate 11 arranged on the mounting plate 9, a locking assembly and an unlocking assembly; the guide strip 10 is provided with two parallel strips, and the sides of the two guide strips 10 are provided with guide grooves 101, and the guide block can slide with the guide groove 101; when the limit block 5 and the seat plate 11 are in contact, the locking assembly can limit the module housing 1 and lock the module housing 1 on the mounting plate 9, and the unlocking assembly is used to release the locking effect of the locking assembly.

[0042] Specifically, Figure 1 and Figure 2 As shown, the limit block 5 is fixed to the upper end of the back of the module housing 1 , the upper guide block 2 is fixed to the upper side of the back of the module housing 1 , and the lower guide block 3 is fixed to the lower side of the back of the module housing 1 .

[0043] Specifically, Figure 2As shown, the guide blocks are symmetrically arranged in two pieces, namely: an upper guide block 2 and a lower guide block 3; the upper guide block 2 and the lower guide block 3 are slidably matched with the guide grooves 101 on the two guide bars 10 respectively.

[0044] Specifically, two upper guide blocks 2 and two lower guide blocks 3 are provided; the two upper guide blocks 2 are located in the same straight line, and the two lower guide blocks 3 are located in the same straight line. The upper guide blocks 2 and the lower guide blocks 3 are slidably matched with the guide grooves 101 on the two guide bars 10 respectively.

[0045] like Figure 2 , Figure 3 As shown, the guide block is an L-shaped slider; Figure 3 As shown, the guide groove 101 is arranged on the side of the guide strip 10 .

[0046] Specifically, two groups of upper guide blocks 2 and lower guide blocks 3 are symmetrically arranged; the two guide bars 10 are also symmetrically arranged, and the openings of the two guide slots 101 face each other. The upper end of the L-shaped slider is fixedly connected to the module housing 1, and the lower end is slidably matched with the guide slot 101.

[0047] Specifically, Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the seat plate 11 is arranged perpendicular to the guide bar 10 and is located on the side of the guide bar 10; the module housing 1 is fixedly provided with a limit block 5, and the limit block 5 is arranged perpendicular to the guide block; when the limit block 5 and the seat plate 11 are in contact with each other, the guide block cooperates with the guide groove 101; the guide block can be locked in the guide groove 101 by a locking assembly. The locking assembly locks the module housing 1 and the mounting plate 9 by locking the guide block.

[0048] Furthermore, when the guide block slides into the guide groove 101, the limit block 5 and the seat plate 11 gradually approach each other until they are in contact; when the guide block slides into the guide groove 101 and the limit block 5 is in contact with the seat plate 11, the locking assembly limits the guide block; and the installation of the module housing 1 is completed.

[0049] In this embodiment, Figure 3 , Figure 5 As shown, the locking component is a locking structure.

[0050] Specifically, Figure 3 , Figure 5 As shown, the guide bar 10 is provided with a locking groove 103 perpendicular to the guide groove 101 ; the locking structure is floatingly installed in the locking groove 103 of the guide bar 10 .

[0051] like Figure 4 , Figure 5 As shown, the guide bar 10 is also provided with a locking groove 103 for installing a locking structure; specifically, as Figure 4 As shown, the locking groove 103 is arranged perpendicular to the guide groove 101 , and the upper end of the locking groove 103 is connected to the guide groove 101 , and the lower end of the locking groove 103 extends to the lower surface of the mounting plate 9 .

[0052] Specifically, Figure 6 As shown, the lock buckle structure includes: a lock buckle 13, a compression spring 18 and a mounting block 19; wherein the lock buckle 13 is elastically mounted on the mounting block 19 through the compression spring 18; when the lock buckle 13 is pressed down, the compression spring 18 is compressed, and the lock buckle 13 moves toward the mounting block 19. The compression spring 18, the lock buckle 13 and the mounting block 19 are all welded and fixed.

[0053] like Figure 5 , Figure 6 As shown, the lock buckle 13 is fixedly installed above the compression spring 18 and protrudes from the lower surface of the guide groove 101. Specifically, the lock buckle 13 is a trapezoidal structure; a trapezoidal locking block 131 is provided at the upper end of the lock buckle 13, and the lower end is fixedly connected to the compression spring 18; a trapezoidal slot 132 is also provided on the side of the lock buckle 13; Figure 6 The trapezoidal locking block 131 at the upper end of the lock buckle 13 protrudes from the lower surface of the guide groove 101 to limit the guide block from sliding in one direction relative to the lock buckle 13 and locking in the reverse direction.

[0054] Specifically, the upper surface of the trapezoidal locking block 131 is a first inclined surface, the lowest end of the first inclined surface is flush with the lower surface of the guide groove 101, and the highest end of the first inclined surface protrudes from the lower surface of the guide groove 101; therefore, when the guide block slides along the guide groove 101, it can slide from the lowest end to the highest end of the first inclined surface, and at the same time cannot slide in the opposite direction due to the side obstruction of the trapezoidal locking block 131.

[0055] During implementation, when the guide block slides along the guide groove 101, it can slide along the first inclined surface of the trapezoidal lock block 131, thereby causing the lock buckle 13 to move downward as a whole, and compressing the compression spring 18 at the same time; until the guide block presses the lock buckle 13 as a whole into the locking groove. After the guide block passes over the lock buckle 13, the lock buckle 13 is reset under the elastic force of the compression spring 18 and protrudes out of the lower surface of the guide groove 101 again; at this time, since the side surface of the trapezoidal lock block 131 is a vertical plane, the guide block is limited by the stopper of the trapezoidal lock block 131 and cannot slide in the opposite direction, and the guide block and the electronic module are automatically locked and positioned by the lock buckle 13.

[0056] Specifically, the mounting block 19 is fixedly connected to the mounting plate 9 by welding or bolting.

[0057] Furthermore, in order to unlock the locking structure, an unlocking component is also provided in this embodiment; the locking structure is used to lock the guide block at the bottom of the module housing 1; the unlocking component is used to release the limiting effect of the locking structure on the guide block.

[0058] In this embodiment, Figure 3 , Figure 4 As shown, the unlocking assembly includes: a slide bar 15, a sliding block 14, a return spring 16 and a pull block 17. The unlocking assembly is used to press down the lock buckle 13 to release the lock of the guide block by the lock buckle 13. The unlocking assembly and the locking assembly are both arranged on the mounting plate 9.

[0059] Specifically, two parallel sliding rods 15 are slidably mounted on the seat plate 11. The sliding rods 15 pass through the seat plate 11 and slide in cooperation. A pull block 17 is fixedly mounted on one end of the sliding rod 15, and a sliding block 14 is fixedly mounted on the other end. Two sliding columns 141 are symmetrically mounted on both ends of the sliding block 14. A return spring 16 is sleeved on the sliding rod 15, and both ends of the return spring 16 abut between the right end surface of the seat plate 11 and the left end surface of the sliding block 14. Figure 4 , Figure 5 shown.

[0060] Furthermore, if Figure 5 , Figure 6 As shown, a slide groove 102 is also provided on the guide bar 10 ; specifically, the slide groove 102 is provided parallel to the guide groove 101 and is located below the guide groove 101 ; the slide groove 102 is aligned with the trapezoidal slot 132 on the lock buckle 13 .

[0061] Furthermore, the end of the sliding column 141 is disposed in the sliding groove 102 and can slide along the sliding groove 102 .

[0062] Specifically, Figure 6 As shown, the trapezoidal slot 132 is an inverted trapezoidal structure; the lower surface of the trapezoidal slot 132 is a second inclined surface; the lowest end of the second inclined surface is flush with the lower surface of the slide slot 102, so that the sliding column 141 can slide from the slide slot 102 into the trapezoidal slot 132, and when the sliding column 141 slides along the lower surface of the trapezoidal slot 132, it can press down the lock buckle 13. When the sliding column 141 contacts the side of the lock buckle slot 132, it can completely press the lock buckle 13 into the locking slot 103.

[0063] Specifically, the first inclined surface of the trapezoidal locking block 131 has the same inclination direction as the second inclined surface of the trapezoidal slot 132; and the height of the second inclined surface is greater than or equal to the first inclined surface, so that after the sliding column 141 slides completely into the trapezoidal slot 132, the lock buckle 13 can be completely pressed into the locking groove of the guide bar 10.

[0064] In this embodiment, Figure 3 , Figure 4 As shown, two slide bars 15, two return springs 16, and two guide bars 10 are symmetrically arranged. At least one set of locking structures is installed on each guide bar 10, and correspondingly, at least one sliding block 14 is fixedly installed on the slide bar 15. Specifically, a set of locking structures is symmetrically arranged on the guide bars 10 on both sides, and can be unlocked by the sliding columns 141 at both ends of the sliding block 14.

[0065] Specifically, in this embodiment, the guide block of the electronic module can slide into the guide groove 101 from the right side of the guide bar 10; when the limit block 5 at the bottom of the module housing 1 contacts the seat plate 11, the guide block is located on the left side of the lock 13 and is restricted by the lock 13 and cannot slide in the opposite direction.

[0066] During installation, the module housing 1 is slidably installed in the guide strip 10 on the mounting plate 9, and the guide block slides into the guide slot 101 from the end of the guide slot 101. When the guide block slides to the lock buckle 13, the guide block continues to slide in the direction of the lock buckle 13 and presses the lock buckle 13 down through the inclined surface of the trapezoidal lock block 131 until the lock buckle 13 is completely pressed into the locking groove of the guide strip 10; when the limit block 5 contacts the seat plate 11, the guide block slides over the lock buckle 13 to release the downward pressure on the lock buckle 13. At this time, the lock buckle 13 rises and protrudes out of the lower surface of the guide slot 101 under the elastic force of the compression spring 18, and the side of the guide block contacts the side of the trapezoidal lock block 131 and is limited by the trapezoidal lock block 131, so that the guide block cannot slide in the opposite direction and the electronic module cannot be separated from the mounting plate 9.

[0067] In this embodiment, the locking buckle 13 and the limit block 5 are used together to limit the sliding of the module housing 1 along the guide groove 101, and the cooperation between the two guide grooves 101 and the guide block is used to limit the module housing 1 from being separated from the guide groove 101, thereby achieving the installation and fixation of the module housing 1 on the mounting plate 9.

[0068] When unlocking, pull the pull block 17, and the pull block 17 pulls the sliding rod 15 and the sliding block 14 to slide, and then the sliding column 141 fixedly connected to the sliding block 14 slides along the sliding groove 102 on the guide bar 10, and the sliding column 141 slides from the sliding groove 102 into the trapezoidal card groove 132 of the lock buckle 13, and slides along the second inclined surface of the trapezoidal card groove 132, and presses down the lock buckle 13 at the same time; until the sliding column 141 contacts the side of the lock buckle card groove 132, and presses the lock buckle 13 into the locking groove of the guide bar 10, at this time, the lock buckle 13 releases the limiting effect on the guide block, and the guide block can slide in the opposite direction along the guide groove 101, and then the module housing 1 can be separated from the guide bar 10, and the disassembly of the electronic module is completed.

[0069] Furthermore, if Figure 1As shown, the electronic module further includes a module body, a rotary switch 6, an indicator light 7, an electrical connector 8, etc. Specifically, the rotary switch 6 and the indicator light 7 are mounted on the front side of the module housing 1, and the electrical connector 8 is mounted on the upper end surface of the module housing 1.

[0070] Specifically, the electronic module is used to control the electromechanical device. An electrical connector 8 of the electronic module is connected to a corresponding connector of the electromechanical device by a cable, two rotary switches 6 are used to select the running speed (low speed, high speed) and running direction (forward, backward, stop) of the electromechanical device, and three indicator lights 7 are used to indicate the normal and faulty forward, backward, and stop states of the electromechanical device.

[0071] The quick-release device of the electronic module of the present invention only needs to fix the mounting plate 9 to the main body structure of the vehicle body, and connect or disassemble the module housing 1 to the mounting plate 9, so as to realize the installation and removal of the electronic module on the main body of the vehicle body.

[0072] In the present invention, the quick-release device for realizing the quick disassembly and assembly of the electronic module is mainly described, and the part of the electronic module for realizing its own function is not used as a limitation to the protection scope of the present invention.

[0073] Example 2

[0074] In a specific implementation of the present invention, the difference from Example 1 is that the locking assembly is used to lock the limit block 5 and the seat plate 11 to achieve locking of the electronic module on the mounting plate 9.

[0075] In this embodiment, the locking assembly is a bolt, and threaded holes are provided on the seat plate 11 on the mounting plate 9 and the limit block 5, and the two are connected by bolts.

[0076] Or, if Figure 7-Figure 12 As shown, in this embodiment, the locking component and the unlocking component are both: a locking pin 4.

[0077] In this embodiment, locking or unlocking is achieved by rotating the locking pin 4. The locking pin 4 is used to lock or unlock the limit block 5 and the seat plate 11 to achieve the limit and unlocking of the module housing 1 on the mounting plate.

[0078] like Figure 7 , Fig.12 As shown, a locking pin 4 is installed on the limit block 5, and a positioning hole 51 is provided.

[0079] Specifically, Fig.10 As shown, the locking pin 4 includes: a handle 41 , a pin 42 , a locking spring 43 and a screw 44 .

[0080] Specifically, the pin 42 is rotatably installed in the pin hole 52 on the limit block 5 , and passes through the pin hole 52 to be fixedly connected to the handle 41 by a screw 44 or by welding; a locking spring 43 is provided between the handle 41 and the limit block 5 .

[0081] Specifically, Fig.11 As shown, two limiting protrusions 442 are symmetrically arranged at the end of the pin 42, and two protrusion slots 53 are arranged on both sides of the pin hole 52; the limiting protrusions 442 can be clamped in the protrusion slots 53 under the elastic force of the locking spring 43.

[0082] Specifically, Fig.10 As shown, the locking spring 43 is sleeved on the thinner side of the pin 42.

[0083] like Figure 8 As shown, the guide bar 10 and the seat plate 11 are fixed on the mounting plate 9 , and the guide bar 10 is provided with a guide groove 101 ; the positioning pin 12 is fixed on the seat plate 11 , and the seat plate 11 is provided with a pin through hole 111 .

[0084] Furthermore, if Figure 8 , Fig. 9 , Fig.10 As shown, the seat plate 11 is provided with a pin through hole 111 ; when the limiting block 5 contacts the seat plate 11 , the end of the pin 42 provided with the limiting protrusion 442 can be passed through the pin through hole 111 by compressing the locking spring 43 .

[0085] Furthermore, when the axes of the two limiting protrusions 442 are parallel to the seat plate 11 , the pin 42 can pass through the pin hole 111 ; when the axes of the two limiting protrusions 442 are perpendicular to the seat plate 11 , the pin 42 cannot pass through the pin hole 111 .

[0086] When the locking pin 4 is installed, the thinner side of the pin 42 is inserted into the pin hole 52 of the limiting block 5 from below, the limiting protrusion 422 below the pin 42 is inserted into the protrusion slot 53 of the limiting block 5, and the locking spring 43, the handle 41, and the screw 44 are installed from above in sequence. The pin 42 and the limiting block 5 realize the design of locking the pin 4 not falling off through the matching design of the limiting protrusion 422 and the protrusion slot 53.

[0087] Preferably, a rectangular anti-rotation groove is provided on the handle 41 to cooperate with the pin 42, and the end of the pin 42 is stuck in the rectangular anti-rotation groove. The handle 41 and the pin 42 of the locking pin 4 are fixed together with a screw 44, which can effectively prevent the screw 44 from loosening due to the rotation of the handle 41.

[0088] Furthermore, a positioning hole 51 is provided on the limit block 5 , and a positioning pin 12 is provided on the seat plate 11 ; when the guide block slides in the guide groove 101 , the positioning pin 12 can be inserted into the positioning hole 51 .

[0089] When the limit block 5 is in contact with the seat plate 11 and the positioning pin 12 is in the plug-in state with the positioning hole 51, the limit block 5 and the seat plate 11 can be locked and unlocked by rotating the locking pin 4, thereby realizing the installation and removal of the electronic module. Specifically, when the electronic module needs to be installed on the mounting plate 9, the lower guide block 3 and the upper guide block 2 are sequentially inserted into the guide groove 101 of the guide bar 10, and then the positioning pin 12 is inserted into the positioning hole 51 of the limit block 5 until the lower surface of the limit block 5 fits the upper surface of the seat plate 11, the locking pin 4 is pressed, the pin 42 is inserted into the pin through hole 111 of the seat plate 11, and then the locking pin 4 is rotated 90°, and the lower limit projection of the pin 42 is clamped on the step of the pin through hole 111 of the seat plate 11, completing the installation and fixation of the electronic module. In addition, the locking spring 43 of the pin 42 can play a role in locking and anti-loosening and anti-vibration.

[0090] When disassembly is required, the pin 42 is rotated in the opposite direction to align the pin 42 with the pin through hole 111. The pin 42 is automatically separated from the seat plate 11 under the elastic force of the locking spring 43, unlocking the limit block 5 and the seat plate 11, so that the electronic module can be removed from the mounting plate 9.

[0091] Example 3

[0092] A specific embodiment of the present invention provides an electronic module installation method for installing the electronic module described in Example 1 or Example 2; the installation method comprises:

[0093] Step S1: Move the module housing 1 and slide the guide block into the guide groove 101 of the guide bar 10;

[0094] Step S2: pushing the module housing 1 to make the guide block slide along the guide groove 101 until the limit block 5 contacts the seat plate 11;

[0095] Step S3: Lock the module housing 1 and the mounting plate 9 by means of a locking assembly, and install the module housing 1 on the mounting plate 9. Figure 4 shown.

[0096] In the step S2 , when the limiting block 5 contacts the seat plate 11 , the positioning hole 51 on the limiting block 5 engages with the positioning pin 12 on the seat plate 11 .

[0097] When the electronic module is installed and locked using the locking assembly of Example 1:

[0098] In the step S3 , when the locking assembly is a lock structure, the guide block is locked by the lock 13 , and the module housing 1 is locked on the mounting plate 9 .

[0099] Specifically, in step S3, when the module housing 1 is locked by the locking structure, the locking method is:

[0100] Step S31: Slide the guide block at the bottom of the module housing 1 into the guide groove 101 of the guide bar 10; specifically, the guide block slides into the guide groove 101 from the end of the guide groove 101, and the upper guide block 2 and the lower guide block 3 slide into the two guide grooves 101 of the two guide bars 10 respectively.

[0101] Step S32: Push the module housing 1 to slide along the guide bar 10, and the guide block slides in the guide groove 101; when the guide block slides to the lock buckle 13, the guide block slides along the first inclined surface of the trapezoidal lock block 131, and presses down the lock buckle 13 at the same time; until the lock buckle 13 is completely pressed into the locking groove of the guide bar 10;

[0102] Step S33: Continue to move the module housing 1 until the limit block 5 contacts the base plate 11. At this time, the guide block slides over the lock buckle 13, releasing the downward pressure on the lock buckle 13; the lock buckle 13 moves upward under the elastic force of the compression spring 18 and protrudes from the lower surface of the guide groove 101. The side of the guide block contacts the side of the trapezoidal lock block 131 and is limited by the trapezoidal lock block 131, so that the guide block cannot slide in the opposite direction and the electronic module cannot be separated from the mounting plate 9.

[0103] Specifically, when the limit block 5 contacts the seat plate 11, the guide block is restricted by the lock 13, so that the module housing 1 cannot slide to the right. At the same time, the limit block 5 is restricted by the seat plate 11, so that the module housing 1 cannot slide to the left. The limit block 5 and the lock 13 jointly limit the position of the module housing 1, so that it is fixed on the mounting plate 9.

[0104] Specifically, when multiple groups of locking structures and guide blocks are provided, when the limiting block 5 contacts the base 11 , each group of guide blocks cooperates with the corresponding locking structure.

[0105] Furthermore, when the electronic module needs to be disassembled, the locking structure needs to be unlocked by the unlocking assembly, and then the locking structure releases the locking effect on the guide block, allowing the guide block and the module housing 1 to slide in the opposite direction and then be removed from the mounting plate 9.

[0106] Specifically, the unlocking process of the unlocking component to the lock structure is as follows:

[0107] Step C1: Pull the pull block 17 outward to make the slide rod 15 and the slide block 14 move synchronously; when the slide block 14 moves, the slide column 141 fixedly connected to the slide block 14 slides along the slide groove 102 on the guide bar 10;

[0108] Step C2: The sliding post 141 slides from the sliding groove 102 into the trapezoidal slot 132 of the lock buckle 13 and slides along the second inclined surface of the trapezoidal slot 132 while pressing down the lock buckle 13;

[0109] Step C3: The sliding post 141 continues to slide along the lock buckle slot 132 until the sliding post 141 contacts the side of the lock buckle slot 132, pressing the lock buckle 13 into the locking slot of the guide slot 10; the locking buckle 13 is released from the limiting effect on the guide block. After the guide block is released from the limiting effect, the guide block can slide in the opposite direction along the guide slot 101, and then the module housing 1 can be separated from the guide bar 10, completing the disassembly of the electronic module.

[0110] Furthermore, after releasing the pulling block 17, the sliding block 14 is reset under the elastic force of the reset spring 16, and the sliding block 14 drives the sliding rod 15 and the sliding column 141 to move synchronously, and the sliding column 141 slides out of the locking slot 132 and slides back into the sliding slot 102; at this time, the sliding column 141 releases the downward pressure on the lock 13, and the lock 13 is reset under the elastic force of the compression spring 18, so that the guide block can be locked and limited again.

[0111] It is worth noting that: by setting the orientation of the trapezoidal locking block 131 of the lock buckle 13, the direction in which the guide block slides into the guide groove 101 (sliding into the left side or the right side) can be changed; and then the pull block 17 is pulled outward or pushed inward to drive the sliding column 141 to press down the lock buckle slot 132 to achieve unlocking; the present application does not limit the setting direction of the lock buckle 13 to be unique, that is, the direction in which the guide block slides into the guide groove 101 is not used as a limitation on the scope of protection of the present invention.

[0112] Furthermore, when the electronic module is installed and locked using the locking assembly of Example 2:

[0113] In the step S3, when the locking component is the locking pin 4, the locking pin 4 is used to lock the limit block 5 and the seat plate 11, so as to achieve the locking of the module housing 1 and the mounting plate 9.

[0114] Specifically, when the locking component is a locking pin 4, the locking method is:

[0115] Step S301: Press the handle 41, the handle 41 pushes the pin 42 to move toward the limit block 5, and compresses the locking spring 43 at the same time;

[0116] Step S302: Push the handle 41 to press the pin 42 into the pin hole 111; after the limiting protrusion 422 passes through the pin hole 111, rotate the handle 41 and the pin 42 by 90 degrees so that the line between the two limiting protrusions 422 is perpendicular to the seat plate 11;

[0117] Step S303: Release the handle 41, and the elastic force of the locking spring 43 pushes the handle 41 to move away from the limit block 5, and then the limit protrusion 422 presses the side of the seat plate 11 under the elastic force of the locking spring 43; at this time, the limit protrusion 422 of the pin 42 is blocked by the seat plate 11 and cannot move, and the limit block 5 is also limited by the seat plate 11 and cannot move relative to the mounting plate 9, thereby completing the limitation and fixation of the module housing 1 and the mounting plate 9.

[0118] During normal use, the upper guide block 2 and the lower guide block 3 are inserted into the guide groove 101, and the positioning pin 12 is inserted into the positioning hole 51 to meet the installation and fixing requirements. Only during long-distance transportation is it necessary to rotate and fix the locking pin 4 to fix the electronic module and the connecting plate as one.

[0119] Furthermore, when the electronic module needs to be removed from the mounting plate 9, the locking pin 4 is rotated 90° in the opposite direction, and under the elastic force of the locking spring 43, the locking pin 4 automatically pops out from the pin through hole 111 of the seat plate 11; the module housing 1 is further pulled to disengage the positioning pin 12 from the positioning hole 51 of the limit block 5, and at the same time, the upper guide block 2 and the lower guide block 3 are disengaged from the guide groove 101 of the guide strips 10 on both sides, completing the removal of the electronic module from the mounting plate 9.

[0120] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
