Description

Technical Field

[0001] This application relates to the field of circuit board technology, and in particular to a circuit board mounting structure and control box. Background Technology

[0002] The Beam Shaping System (BSM) is an important component of radiation therapy equipment. It is used to adjust the shape, intensity, and direction of the radiation beam or particle beam to precisely match the contour of the tumor and reduce damage to surrounding healthy tissues.

[0003] The BSM control box has circuit boards located at both the top and bottom. In related technologies, when the circuit board at the bottom of the control box needs maintenance, the circuit board and accessories at the top of the control box must be removed first before the circuit board at the bottom can be repaired, making the maintenance process for the circuit board at the bottom of the control box cumbersome.

[0004] Therefore, simplifying the maintenance procedures for the circuit boards located below the control box has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] This application proposes a circuit board mounting structure to simplify maintenance procedures for the circuit boards located beneath the control box. This application also proposes a control box.

[0006] To achieve the above objectives, this application provides a circuit board mounting structure suitable for a control box, comprising:

[0007] A mounting plate has a first surface and a second surface arranged opposite to each other, wherein a circuit board is mounted on the first surface.

[0008] A pushing component, installed inside the control box and located at the first end of the mounting plate, is used to push the mounting plate to move in a first direction so that the interface of the circuit board is inserted into the mounting hole of the control box;

[0009] A reset component is used to push the mounting plate to move in a second direction so that the interface slides out of the mounting hole, the second direction being opposite to the first direction;

[0010] A sliding assembly has a slider and a slide rail. The slider is connected to the second surface, and the slide rail is slidably connected to the control box. The circuit board can slide out of the control box along a third direction via the sliding assembly after sliding out of the mounting hole at the interface. The third direction is perpendicular to the first direction.

[0011] Preferably, in the above-described circuit board mounting structure, the pushing component includes a stop block and a pull block. The cross-sections of the stop block and the pull block along the plane of the mounting plate are right-angled trapezoids or right-angled triangles. The stop block is connected to the control box, and a channel for the movement of the pull block is formed between the stop block and the first end of the mounting plate.

[0012] The inclined surface of the stop block and the inclined surface of the pull block are in contact with each other. One of the right-angled surfaces of the pull block is in contact with the first end of the mounting plate. As the circuit board slides out of the control box, the width of the stop block gradually decreases and the width of the pull block gradually increases.

[0013] Preferably, in the above-described circuit board mounting structure, the pull-out block has a connecting plate with a connecting hole. After the interface is inserted into the mounting hole, the connecting plate is locked to the stop block through the connecting hole to prevent the pull-out block from sliding.

[0014] Preferably, in the above-described circuit board mounting structure, the sliding component is located between the reset component and the pushing component, and a channel for the pull block to move is formed between the slide and the inclined surface of the stop.

[0015] Preferably, the circuit board mounting structure further includes a locking component for locking the mounting plate when the interface is inserted into the mounting hole.

[0016] The locking assembly includes a first locking plate, a second locking plate, and a locking pin.

[0017] The first locking plate is installed at the first end of the mounting plate, and the first locking plate has a first locking hole.

[0018] The second locking plate is located above the pushing assembly. The second locking plate is connected to the stop block or the control box and is parallel to the first locking plate. A space is formed between the second locking plate and the pull block for the first locking plate to be inserted. The second locking plate has a second locking hole. The second locking hole corresponds to the position of the first locking hole when the interface is inserted into the assembly hole. The second locking plate and the first locking plate are locked together by locking pins that cooperate with the first locking hole and the second locking hole.

[0019] Preferably, in the above-described circuit board mounting structure, the locking pin includes:

[0020] A pin, wherein a cavity is formed within the pin, and the opening end of the pin corresponding to the cavity is conical.

[0021] A ball bearing is located at the open end of the cavity, and a spring is provided inside the cavity to press the ball bearing at the open end.

[0022] Preferably, in the above-described circuit board mounting structure, the reset assembly includes a fixing block, a guide rod, and a compression spring. The fixing block is connected to the control box. The guide rod is arranged along a second direction. The first end of the guide rod cooperates with the sliding rod of the fixing block. The second end of the guide rod is connected to the slide rail. A compression spring is sleeved on the guide rod. The two ends of the compression spring abut against the fixing block and the slide rail, respectively.

[0023] Preferably, the circuit board mounting structure further includes a clamping component for clamping a second end of the mounting plate when the interface is inserted into the mounting hole, the second end being opposite to the first end.

[0024] Preferably, in the above-described circuit board mounting structure, the clamping assembly includes a clamping plate and a insert plate. The clamping plate is connected to the control box, and the clamping plate has a slot facing a first end of the mounting plate. The insert plate is connected to the second surface, and the insert plate is inserted into the slot.

[0025] A control box includes a circuit board mounting structure, wherein the circuit board mounting structure is the circuit board mounting structure described in any of the above embodiments.

[0026] The circuit board mounting structure provided in this application includes a mounting plate, a pushing assembly, a resetting assembly, and a sliding assembly. The mounting plate has a first surface and a second surface. The circuit board is mounted on the first surface of the mounting plate. The pushing assembly is installed inside a control box and located at the first end of the mounting plate. The pushing assembly pushes the mounting plate to move in a first direction, allowing the interface of the circuit board to be inserted into the mounting hole of the control box. The resetting assembly is installed inside the control box and is used to push the mounting plate to move in a second direction, allowing the interface of the circuit board to slide out of the mounting hole of the control box, thus releasing the restriction of the mounting hole on the circuit board. The sliding assembly is located on the second surface of the mounting plate and includes a slider and a slide rail. The slider is connected to the second surface, and the slide rail is slidably connected to the control box. After the interface of the circuit board slides out of the mounting hole, the mounting plate can slide out of the control box in a third direction via the sliding assembly. When the circuit board requires repair, the pushing component does not apply a force in the first direction to the mounting plate, while the resetting component applies a force in the second direction to the slide rail. The slide rail, through a slider, moves the mounting plate in the second direction, causing the circuit board interface to slide out of the mounting hole in the control box. The mounting plate is then removed from the control box via the sliding component for circuit board repair. After repair, the mounting plate is inserted into the control box via the sliding component. The pushing component applies a force in the first direction to the mounting plate, moving it in the first direction until the circuit board interface is inserted into the mounting hole in the control box. The mounting plate, through a slider, moves the slide rail within the control box. This circuit board mounting structure allows for the separate disassembly of the lower circuit board of the control box, eliminating the need to first disassemble the upper circuit board and accessories when the lower circuit board requires repair, thus simplifying the repair process for the lower circuit board.

[0027] This solution also discloses a control box, including a circuit board mounting structure, which is the circuit board mounting structure described in any of the above solutions. Since the circuit board mounting structure has the aforementioned technical effects, the control box having this circuit board mounting structure also has the same technical effects, and will not be elaborated further here.

[0041] Figure 1 This is a schematic diagram of the circuit board mounting structure and circuit board assembly disclosed in this solution. The circuit board mounting structure disclosed in this solution is applicable to control boxes and is used to realize the installation of the lower circuit board 2 inside the control box.

[0042] The circuit board mounting structure disclosed in this solution is applicable not only to the mounting of the lower circuit board 2 of the control box, but also to other devices that require mounting of multi-layer circuit boards.

[0043] The circuit board mounting structure includes a mounting plate 1, a pushing assembly 3, a reset assembly 4, and a sliding assembly 5, wherein...

[0044] Mounting plate 1 has a first surface and a second surface, the first surface and the second surface are opposite to each other, the first surface is parallel to the plane where the circuit board 2 is located, the first surface of mounting plate 1 mounts the circuit board 2, and optionally, the first surface and the second surface are parallel.

[0045] The push component 3 is installed inside the control box and located at the first end of the mounting plate 1. The push component 3 pushes the mounting plate 1 to move in the first direction so that the interface of the circuit board 2 is inserted into the assembly hole of the control box, thereby realizing the assembly of the circuit board 2 on the control box. The push component 3 continuously applies a pushing force to the mounting plate 1 to fix the position of the mounting plate 1.

[0046] The connectors of circuit board 2 are concentrated at one end of the circuit board, and the end of circuit board 2 with connectors corresponds to the second end of mounting plate 1. The first end of mounting plate 1 and the second end of mounting plate 1 are opposite each other. Reset assembly 4 is installed inside the control box. Reset assembly 4 is used to push mounting plate 1 to move in the second direction, so that the interface of circuit board 2 slides out of the mounting hole of the control box, releasing the mounting hole from the restriction of circuit board 2. The first direction and the second direction are opposite to each other. Figure 1 For reference, the first direction is left and the second direction is right;

[0047] The sliding component 5 is located on the second surface of the mounting plate 1. After the interface of the circuit board 2 slides out of the mounting hole, the mounting plate 1 can drive the circuit board 2 to slide out of the control box along a third direction via the sliding component 5. The third direction is perpendicular to the first direction. Figure 1 For reference, the third direction is front and back. In some embodiments, the sliding component 5 includes a slider 51 and a slide rail 52, the slider 51 is connected to the second surface, and the slide rail 52 is slidably connected to the control box.

[0048] like Figure 1 , Figure 2 and Figure 3 As shown, the circuit board 2, the pushing component 3, the reset component 4 and the sliding component 5 are distributed on both sides of the mounting plate 1. The reset component 4 is located between the first end and the second end of the mounting plate 1. The reset component 4 does not occupy the second end of the mounting plate 1, ensuring the smooth fit between the socket and the mounting hole of the circuit board 2.

[0049] When circuit board 2 requires repair, the pushing component 3 does not apply a pushing force in the first direction to the mounting plate 1, and the resetting component 4 applies a force in the second direction to the slide rail 52. The slide rail 52, through the slider 51, drives the mounting plate 1 to move in the second direction, causing the interface of circuit board 2 to slide out of the mounting hole of the control box. Then, the mounting plate 1 drives circuit board 2 to be removed from the control box through the sliding component 5 for repair. Figure 1 As shown;

[0050] After the circuit board 2 is repaired, the mounting plate 1 drives the circuit board 2 into the control box via the sliding assembly 5. The pushing assembly 3 applies a thrust in the first direction to the mounting plate 1, pushing the mounting plate 1 to move in the first direction until the interface of the circuit board 2 is inserted into the mounting hole of the control box. The mounting plate 1 then slides within the control box via the slider 51 and the slide rail 52. Figure 2 As shown.

[0051] The sliding component 5 is slidably engaged with the control box. The sliding direction of the sliding component 5 is parallel to the first direction and the second direction. The sliding component can slide along the first direction and the second direction.

[0052] The circuit board mounting structure disclosed in this solution enables the separate disassembly of the lower circuit board 2 of the control box. This eliminates the need to first disassemble the upper circuit board 2 and accessories of the control box when the lower circuit board 2 of the control box needs maintenance, thus simplifying the maintenance steps of the lower circuit board 2 of the control box.

[0053] In this solution, the mounting plate 1 needs to be slid out from the control box. The pushing component 3 and the reset component 4 are not connected, but the pushing component 3 and the reset component 4 are connected to the control box. The mounting plate 1 is connected to the slider 51, the slider 51 is connected to the slide rail 52, and the slide rail 52 is connected to the reset component 4. That is, the slide rail 52 is connected to the control box through the reset component 4, and the slide rail 52 fixes the mounting plate 1 in the control box through the slider 51, so as to realize the positioning of the mounting plate 1 in the plane perpendicular to the circuit board 2.

[0054] like Figure 1 , Figure 2 and Figure 3 As shown, an embodiment of the pushing component 3 is disclosed. The pushing component 3 includes a stop block 31 and a pull block 32. The stop block 31 is connected to the control box, and the pull block 32 is a movable block. A channel for the movement of the pull block 32 is formed between the stop block 31 and the first end of the mounting plate 1. In this embodiment, the cross-sections of the stop block 31 and the pull block 32 along the plane of the mounting plate 1 are right-angled triangles or right-angled trapezoids (e.g., ...). Figure 4 As shown, the inclined surface of the stop block 31 and the inclined surface of the pull-out block 32 are in contact with each other. One right-angled surface of the pull-out block 32 is in contact with the first end of the mounting plate 1. As the circuit board 2 slides out of the control box, the width of the stop block 31 gradually decreases, and the width of the pull-out block 32 gradually increases. For ease of subsequent description, the end of the stop block 31 with the larger width is named the first end of the stop block 31, and the end of the stop block 31 with the smaller width is named the second end of the stop block 31. Similarly, the end of the pull-out block 32 with the smaller width is named the first end of the pull-out block 32, and the end of the pull-out block 32 with the larger width is named the second end of the pull-out block 32.

[0055] The first end of the pull-out block 32 is inserted into the channel, and the pull-out block 32 moves against the inclined surface of the stop block 31. As the pull-out block 32 is inserted, the width of the pull-out block 32 gradually increases. The pull-out block 32 pushes the mounting plate 1 to move in the first direction. After the pull-out block 32 is fully inserted into the channel, the interface of the circuit board 2 is inserted into the mounting hole of the control box, and the second end of the pull-out block 32 is flush with the second end of the stop block 31.

[0056] When the circuit board 2 needs maintenance, the pull block 32 is pulled out from the channel, and the mounting plate 1 can move in the second direction under the action of the reset component 4.

[0057] The pushing component 3 is not limited to the above embodiments, but can also be other linear drive components that can push the mounting plate 1 to move in the first direction, such as a lead screw assembly, a telescopic cylinder or a gear and rack assembly, etc.

[0058] like Figure 2 and Figure 3 As shown, the second end of the pull-out block 32 has a connecting plate 321 with a connecting hole. After the insertion port is inserted into the assembly hole, the connecting plate 321 is locked onto the stop block 31 through the connecting hole to lock the pull-out block 32, prevent the pull-out block 32 from moving in the channel, and ensure that the position of the circuit board 2 will not change when there is no need for maintenance.

[0059] The connection between the connecting plate 321 and the stop block 31 can be a bolt connection.

[0060] The pull-out block 32 is not limited to being locked onto the stop block 31, but can also be locked onto the control box.

[0061] The sliding component 5 can be located between the reset component 4 and the pushing component 3, or between the reset component 4 and the second end of the mounting plate 1, or simultaneously between the reset component 4 and the pushing component 3 and between the reset component 4 and the second end of the mounting plate 1.

[0062] like Figure 1 , Figure 2 and Figure 3 As shown, in an embodiment where the sliding component 5 is located between the reset component 4 and the push component 3, a channel for the pull block 32 to move is formed between the slide 52 and the inclined surface of the stop block 31.

[0063] In this embodiment, the slider 51 can fit against the right-angled surface of the pull-out block 32, which guides and limits the movement of the pull-out block 32, thereby improving the stability of the movement of the pull-out block 32.

[0064] After the slide rail 52 and the slider 51 are engaged, the slider 51 can only move along a third direction, and cannot move along a direction perpendicular to the plane where the mounting plate 1 is located. In other words, the slide rail 52 limits the slider 51 in the direction perpendicular to the plane where the mounting plate 1 is located, so as to fix the mounting plate 1 in the control box.

[0065] In some embodiments, the reset assembly 4 includes a fixing block 41, a guide rod 42, and a compression spring 43. The fixing block 41 is mounted on the control box, the guide rod 42 is arranged along the second direction, the first end of the guide rod 42 is slidably engaged with the fixing block 41, the second end of the guide rod 42 is connected to the slide rail 52, and the compression spring 43 is sleeved on the guide rod 42. The two ends of the compression spring 43 abut against the fixing block 41 and the slide rail 52, respectively.

[0066] When the push component 3 pushes the mounting plate 1 to move in the first direction, the mounting plate 1 drives the slide rail 52 and guide rod 42 to slide through the slider 51. The slide rail 52 and the fixing block 41 squeeze the compression spring 43. After the socket is inserted into the assembly hole, the mounting plate 1 stops moving, the slider 51 stops moving, and the slide rail 52 does not squeeze the compression spring 43 further.

[0067] When the circuit board 2 is in need of maintenance, the push component 3 does not apply a push force to the mounting plate 1 in the first direction. The compression spring 43 releases energy and pushes the slide rail 52 to move in the second direction. The slide rail 52 drives the mounting plate 1 to move through the slider 51, and the socket slides out of the assembly hole.

[0068] The reset component 4 disclosed in this solution can not only apply a thrust in the second direction to the mounting plate 1, but also achieve a sliding connection between the slide rail 52 and the control box. This eliminates the need for a separate structure to achieve the sliding fit between the slide rail 52 and the control box, simplifying the circuit board mounting structure. For example... Figure 1 , Figure 2 and Figure 3 As shown, the fixing block 41 is elongated and is arranged along the third direction; at least two guide rods 42 are arranged along the length direction of the fixing block 41, and the at least two guide rods 42 are evenly distributed along the length direction of the fixing block 41 to improve the guiding effect of the guide rods 42 on the slide 52; at least one guide rod 42 is provided with a compression spring 43, and optionally, the compression springs 43 are evenly distributed along the length direction of the slide 52 to ensure that the sliding speed is consistent at all points of the slide 52.

[0069] The reset component 4 is not limited to the above embodiments; it can also be a telescopic cylinder or a rack and pinion assembly. In embodiments where the reset component 4 is a telescopic cylinder or a rack and pinion assembly, when the reset component 4 is not working, the telescopic cylinder or rack and pinion assembly is in its initial position. When the reset component 4 is working, the telescopic cylinder or rack and pinion assembly is activated, contacts the slide rail 52, and drives the slide rail 52 to move. In embodiments where the reset component 4 is a telescopic cylinder or a rack and pinion assembly, a track structure for sliding the slide rail can be provided inside the control box.

[0070] The circuit board mounting structure disclosed in this solution also includes a clamping component 6, which is used to clamp the second end of the mounting plate 1 after the interface is inserted into the mounting hole. At this time, the mounting plate 1 is fixed in the control box by the sliding component 5 and the clamping component 6.

[0071] In some embodiments, the clamping assembly 6 includes a clamping plate 61 and an insert plate 62. The clamping plate 61 is connected to the control box, and the insert plate 62 is connected to the second surface of the mounting plate 1. The insert plate 62 moves synchronously with the mounting plate 1. Figure 1 As shown, the clamping plate 61 has a slot with the opening facing the first end of the mounting plate 1, and the insert plate 62 is inserted into the slot.

[0072] Figure 1 The middle insert plate 62 is inserted into the slot, and the slot wall applies a force perpendicular to the plane of the mounting plate 1 to the insert plate 62 to prevent the mounting plate 1 from vibrating in a direction perpendicular to its own plane.

[0073] To facilitate insertion of the insert plate 62 into the slot, the insert plate 62 has an inclined surface that slopes away from the mounting plate 1, and the slot wall is a guide inclined surface that cooperates with the inclined surface of the insert plate 62.

[0074] The insert plate 62 and the mounting plate 1 can be integrally formed, welded together, or bolted together, etc.

[0075] The control box contains a mounting block with slots. The mounting block can be connected to the control box by welding, integral molding, or bolting.

[0076] The height of the mounting block along the plane perpendicular to the mounting plate 1 is equal to the height of the sliding component 5 along the plane perpendicular to the mounting plate 1.

[0077] The height of the fixing block 41 along the plane perpendicular to the mounting plate 1 is less than the height of the sliding component 5 along the plane perpendicular to the mounting plate 1, so as to reduce the contact area between the mounting plate 1 and the circuit board mounting structure during the sliding process and reduce the sliding friction of the mounting plate 1.

[0078] The clamping component 6 is not limited to the above embodiments. The clamping component 6 can also clamp the mounting plate 1 by snap-fit, bolt-fit, or magnetic connection.

[0079] The circuit board mounting structure disclosed in this solution also includes a locking component 7, which is used to lock the mounting plate 1 after the interface is inserted into the mounting hole.

[0080] like Figure 3 As shown, the locking assembly 7 includes a first locking plate 71, a second locking plate 72, and a locking pin 73.

[0081] A first locking plate 71 is installed at the first end of the mounting plate 1. A first locking hole is provided on the first locking plate 71. The height of the first locking plate 71 is lower than the first surface.

[0082] The second locking plate 72 is located above the pushing assembly 3. The second locking plate 72 is connected to the side plate of the control box or is set on the stop block 31. The second locking plate 72 is parallel to the first locking plate 71. The lower surface of the second locking plate 72 and the pull block 32 form a space for the first locking plate 71 to be inserted. The second locking plate 72 has a second locking hole.

[0083] When the interface is inserted into the assembly hole, the first locking hole and the second locking hole are positioned opposite each other. The locking pin 73 is inserted into the first locking hole and the second locking hole, locking the second locking plate 72 onto the first locking plate 71.

[0084] The circuit board mounting structure disclosed in this solution fixes the second end of the mounting plate 1 by clamping component 6, fixes the first end of the mounting plate 1 by locking component 7, and fixes the portion of the mounting plate 1 located between the first end and the second end by sliding component 5.

[0085] like Figure 6 The diagram shows the structure of the locking pin 73. The locking pin 73 includes a pin 731, a spring, and a ball 732. The pin 731 has a cavity, and the opening end of the pin 731 corresponding to the cavity is conical. The ball 732 is located at the opening end of the cavity, and a spring is provided in the cavity to press the ball 732 at the opening end.

[0086] The locking pin 73 is pre-installed in the second locking hole. After the pull block 32 is fully inserted, the second locking hole corresponds to and is connected to the first locking hole. The ball 732 automatically penetrates into the first locking hole under the action of the spring, thereby locking the first locking plate 71 and the second locking plate 72. When it is necessary to release the locking of the first locking plate 71 and the second locking plate 72, the pull block 32 is pulled out from the channel, and the mounting plate 1 moves under the pushing force of the compression spring 43, which at the same time drives the first locking plate 71 to move, squeezing the ball 732. The ball 732 retracts into the cavity of the pin 731.

[0087] The circuit installation structure disclosed in this solution allows for automatic unlocking and locking of the locking component 7, eliminating the need for manual operation and making it simple and convenient to use.

[0088] This solution also discloses a control box, including a circuit board mounting structure, wherein the circuit board mounting structure is the circuit board mounting structure described in any of the above solutions.

[0089] Since the circuit board mounting structure has the above-mentioned technical effects, the control box with the circuit board mounting structure also has the same technical effects, which will not be elaborated here.
