Description

Technical Field

[0001] This utility model relates to the field of power electronics technology, and more specifically, to a power module mounting base and a charging pile. Background Technology

[0002] In existing technologies, power module installation and maintenance typically employs bolt fastening. This necessitates the use of tools for complex fastener removal and installation, a laborious process that can easily affect the stability of surrounding circuitry and the module itself. Especially for heavy power modules, the lack of effective support and guidance during disassembly makes the process extremely difficult and carries the risk of detachment. Furthermore, when performing maintenance in confined spaces, tools must be inserted into the limited space for repairs, or fasteners must be removed to extract the power module for inspection, further increasing the complexity and safety risks of maintenance work. Utility Model Content

[0003] To address the shortcomings of existing technologies, a power module mounting base and charging pile are provided, which can reduce the complexity of maintenance operations.

[0004] To achieve the above objectives, the following technical solution is provided: a power module mounting base, including a frame;

[0005] The frame has several mounting cavities;

[0006] The mounting cavity is provided with a sliding plate that is slidably connected to the mounting cavity, and a power module is mounted on the sliding plate;

[0007] A locking device is provided on the sliding plate;

[0008] The locking device is used to lock or unlock the connection between adjacent sliding plates;

[0009] When the locking device locks the connection between adjacent sliding plates, the adjacent locked sliding plates are pulled out simultaneously through the single sliding plate.

[0010] When the locking device releases the connection between adjacent sliding plates, the power module on the sliding plate is pulled out.

[0011] In a further optimization of this utility model, the locking device includes a force-applying component mounted on the sliding plate and a pressing part mounted on the force-applying component;

[0012] The pressing part is slidably connected to the force-applying part;

[0013] A first mating part is provided on one side of the sliding plate, and a second mating part is provided on the other side;

[0014] The pressing part controls the interaction between the first mating part and the second mating part on the adjacent sliding plate to lock or unlock the adjacent sliding plate.

[0015] A further optimization of this utility model is that the sliding plate is provided with a channel on one side corresponding to the first mating part for the first mating part to pass through;

[0016] A first spring is provided on the first mating part;

[0017] The first spring is connected to the first mating part and the channel, and at least allows the first mating part to maintain a tendency to move away from the adjacent second mating part;

[0018] A limiting element is provided on the pressing part;

[0019] The limiting member is connected to the pressing part and is used to limit the movement of the first mating part away from the adjacent second mating part.

[0020] A further optimization of this utility model is that a second spring is provided on the pressing part;

[0021] The second spring is used to reset the pressing part after being pressed, and also to keep the limiting part in contact with the first mating part.

[0022] A further optimization of this utility model is that a first guide surface is provided at one end of the first mating part near the adjacent second mating part;

[0023] A second guide surface is provided at the end of the first mating part near the limiting member;

[0024] When the sliding plate pushes the first mating part in, it abuts against the adjacent sliding plate through the first guide surface, causing the first mating part to move into the channel to avoid it, so that the sliding plate can be pushed in.

[0025] When the first mating part and the second mating part are in the same position, the second spring drives the limiting member to move and abut against the second guide surface, so as to drive the first mating part to move out of the channel and form a mating with the second mating part to lock the adjacent sliding plate.

[0026] When the pressing part is pressed, the pressing part moves the limiting member to form a clearance space. The first spring drives the first mating part to move into the channel and unlocks it with the adjacent second mating part, thereby pulling out the sliding plate.

[0027] A further optimization of this utility model is that the frame is provided with a slide rail and a through groove;

[0028] At least one threaded hole is provided on the sliding plate at the position corresponding to the through slot;

[0029] The sliding plate is mounted on a track and moves along a fixed trajectory of the track;

[0030] The bolt passes through the through groove and is threaded into the threaded hole to prevent the sliding plate from disengaging from the slide rail.

[0031] A further optimization of this utility model is that the frame is provided with positioning holes;

[0032] Positioning elements are provided on the power module at the positions corresponding to the positioning holes;

[0033] The positioning element has threads;

[0034] When the sliding plate pushes the power module in, the positioning component passes through the positioning hole and is threadedly connected to the nut.

[0035] A charging pile includes a housing and a module mounting base installed inside the housing;

[0036] The module mounting bracket is as described above;

[0037] The housing is provided with a first receiving compartment for mounting module mounting bases and a second receiving compartment for mounting electronic components;

[0038] The module mounting bracket connects to the electronic components.

[0039] This technical solution offers the following advantages: By incorporating locking devices on each sliding plate, enabling them to lock or unlock with adjacent sliding plates, when maintaining multiple adjacent power modules, the locking devices connect these modules as a single unit. Operating a single sliding plate allows all locked modules to be pulled out in unison, significantly improving maintenance efficiency. When only a single module needs maintenance, keeping the locking devices unlocked allows each sliding plate to be pulled out independently, providing flexible operation without affecting the operation of other modules.

[0046] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0047] Reference Figure 1-5 As shown, a power module mounting base includes a frame;

[0048] The frame has several mounting cavities;

[0049] The mounting cavity is provided with a sliding plate that is slidably connected to the mounting cavity, and a power module is mounted on the sliding plate;

[0050] A locking device is provided on the sliding plate;

[0051] The locking device is used to lock or unlock the connection between adjacent sliding plates;

[0052] When the locking device locks the connection between adjacent sliding plates, the adjacent locked sliding plates are pulled out simultaneously through the single sliding plate.

[0053] When the locking device releases the connection between adjacent sliding plates, the power module on the sliding plate is pulled out.

[0054] like Figure 1 As shown, the frame serves as the main supporting structure, and its internal mounting cavities provide independent and orderly storage space for each power module.

[0055] Each power module is fixedly installed on an independent unit, such as... Figure 2 On the sliding plate shown;

[0056] The power module is placed on the sliding plate, and a limiting protrusion is formed by setting a protrusion along the circumferential edge of the sliding plate to restrict the power module from detaching.

[0057] The sliding plate and the corresponding mounting cavity on the frame form a sliding connection. For example, through the cooperation of the slide rail and the slide groove, the sliding plate can extend or retract relative to the frame along a preset straight trajectory, thereby driving the power module to extend or retract relative to the frame, so as to carry out the maintenance and inspection of the power module.

[0058] A locking device is provided on the sliding plate, which switches between locking (connected state) and unlocking (separated state) two adjacent sliding plates;

[0059] When multiple power modules need to be maintained or replaced as a whole, the operator pulls out a single sliding plate and unlocks the module that does not need to be pulled out. The movement of the sliding plate will transmit driving force through the locking device, thereby driving the adjacent sliding plate locked with it and the power module installed on it to be smoothly pulled out of the frame along the sliding trajectory of the mounting cavity.

[0060] This process enables the synchronous and coordinated extraction of multiple modules, eliminating the need for separate disassembly and extraction of each module.

[0061] Conversely, when the locking device is in the unlocked state, the interlock between each sliding plate is released. At this time, any sliding plate can be operated individually, which will only pull out itself and its power module without affecting the position of other sliding plates. This is suitable for scenarios where a single module can be repaired or replaced independently.

[0062] Compared with existing technologies, this solution simplifies the single pull-out process by controlling the locking and unlocking of the connection between adjacent sliding plates through the above-mentioned locking device. It also adds selective linkage or independent pull-out operation, reducing the safety risks caused by tool operation and heavy modules. By pulling out the power module for maintenance, the maintenance operation process is not only simplified, but also has multiple pull-out or push-in selection modes, and the maintenance efficiency is improved.

[0063] Preferably, the locking device includes a force-applying member mounted on the sliding plate and a pressing part mounted on the force-applying member;

[0064] The pressing part is slidably connected to the force-applying part;

[0065] A first mating part is provided on one side of the sliding plate, and a second mating part is provided on the other side;

[0066] The pressing part controls the interaction between the first mating part and the second mating part on the adjacent sliding plate to lock or unlock the adjacent sliding plate.

[0067] The force-applying component is fixedly installed on the sliding plate and is used to grip and apply force when pulling or pushing the sliding plate.

[0068] like Figure 2 and Figure 3As shown, the pressing part and the force-applying part are connected in a sliding manner. The sliding connection between the pressing part and the force-applying part can be achieved by the cooperation of the guide rod and the guide hole or the cooperation of the telescopic rod and the spring.

[0069] This allows the pressing part to press and reset relative to the force-applying part in a specific direction (consistent with the pulling direction of the sliding plate);

[0070] A first mating part is provided on one side of the sliding plate, and a second mating part is provided on the other side symmetrically. The first mating part and the second mating part are designed to be able to engage or disengage with each other, such as protrusions and grooves, hooks and hanging rings, etc.

[0071] When it is necessary to lock two adjacent sliding plates, push in a single sliding plate to install it in the mounting cavity, and then push in the adjacent sliding plate (left or right, right in this example). Press the pressing part on the sliding plate to retract the first mating part, so that it can be successfully pushed into the mounting cavity. When the first mating part on the right sliding plate corresponds to the second mating part on the left sliding plate, release the pressing part to allow the first mating part to be smoothly inserted into the second mating part, thus completing the locking.

[0072] When unlocking is required, press the pressing part on the right sliding plate to retract the first mating part and disengage it from the second mating part on the left, thus completing the unlocking process.

[0073] The above is an example. At the same time, the first mating part and the second mating part can also be magnets that attract each other and work together. The pressing part controls the magnetism of the first mating part and the second mating part by controlling the power on and off of the first mating part and the second mating part through an electrical signal, so as to lock or unlock them.

[0074] Alternatively, the first and second mating parts can also be hooks that mate with hanging rings, with the pressing part driving the hook or hanging ring to rotate or move for mating;

[0075] The cooperation between the first mating part, the second mating part, and the pressing part is not limited to the examples mentioned above; it is possible to lock or unlock the first mating part and the second mating part by means of the pressing part.

[0076] Preferably, the sliding plate has a channel on one side corresponding to the first mating part for the first mating part to pass through;

[0077] A first spring is provided on the first mating part;

[0078] The first spring is connected to the first mating part and the channel, and at least allows the first mating part to maintain a tendency to move away from the adjacent second mating part;

[0079] A limiting element is provided on the pressing part;

[0080] The limiting member is connected to the pressing part and is used to limit the movement of the first mating part away from the adjacent second mating part.

[0081] like Figure 3 As shown, the channel is opened on the side wall of the sliding plate, providing a path and spatial guidance for the reciprocating movement of the first mating part;

[0082] The first mating part is slidably disposed in the channel, and the two ends of the first spring are respectively connected to the first mating part and the inner wall of the channel. Its preload or pretension is configured to always give the first mating part a tendency to contract towards the inside of the channel (i.e. away from the adjacent sliding plate).

[0083] Without external force intervention, the first spring attempts to keep the first mating part in the retracted position to prevent it from accidentally extending and causing interference;

[0084] A limiting member is connected to the pressing part. The limiting member moves with the pressing part. When the pressing part is in the initial (unpressed) position, the limiting member is in a specific position that can block or limit the first mating part from retracting into the channel under the action of the first spring, so that it is at least partially kept in the preparatory position of extending out of the channel to engage with the second mating part.

[0085] When it is necessary to retract the first mating part to unlock, press the pressing part. The pressing part moves the limiting member together, thereby releasing the obstruction of the limiting member on the first mating part. The restoring force of the first spring is released, pulling the first mating part back into the channel, so that it is completely disengaged from the engagement area with the adjacent second mating part, thus achieving unlocking.

[0086] Preferably, a second spring is provided on the pressing part;

[0087] The second spring is used to reset the pressing part after being pressed, and also to keep the limiting part in contact with the first mating part.

[0088] The second spring acts on the pressing part, and its installation method can be as follows: it can be sleeved on the guide component between the pressing part and the force-applying component, or its two ends can abut against the corresponding support surfaces of the pressing part and the force-applying component, or as shown in the example. Figure 3 As shown, it is fitted onto the limiting component;

[0089] The second spring is pre-compressed or pre-stretched, thereby providing a restoring force to the pressing part toward its initial position (i.e., the position when it is not pressed);

[0090] When the operator presses the pressing part to perform the unlocking operation, it needs to overcome the elastic force of the second spring. After the pressing (i.e. unlocking) action is completed, once the pressing force is released, the restoring force of the second spring will drive the pressing part back to the initial position through the drive limiter.

[0091] During this process, as the limiting component resets, it also returns to its position where it can prevent the first mating part from retracting into the channel.

[0092] This pushes out the first mating part, allowing it to extend outside the channel and lock with the second mating part.

[0093] The second spring not only enables the pressing part to have an automatic reset function, realizing convenient operation (no need for manual return), but also ensures that the pressing part and the limiting part are in a fixed position under normal conditions, keeping the first mating part partially exposed outside the channel, maintaining the locked state of the adjacent sliding plates. At the same time, through the connection, when a single power module encounters vibration, the force transmitted to the sliding plate will be distributed to the other connected sliding plates, thereby making the power module installation more stable and less prone to displacement due to vibration.

[0094] Preferably, a first guide surface is provided at one end of the first mating part near the adjacent second mating part;

[0095] A second guide surface is provided at the end of the first mating part near the limiting member;

[0096] When the sliding plate pushes the first mating part in, it abuts against the adjacent sliding plate through the first guide surface, causing the first mating part to move into the channel to avoid it, so that the sliding plate can be pushed in.

[0097] When the first mating part and the second mating part are in the same position, the second spring drives the limiting member to move and abut against the second guide surface, so as to drive the first mating part to move out of the channel and form a mating with the second mating part to lock the adjacent sliding plate.

[0098] When the pressing part is pressed, the pressing part moves the limiting member to form a clearance space. The first spring drives the first mating part to move into the channel and unlocks it with the adjacent second mating part, thereby pulling out the sliding plate.

[0099] like Figure 2 and Figure 3 As shown, the first guide surface is located at one end of the first mating part (i.e., the end facing the adjacent sliding plate) and is designed as an inclined surface;

[0100] When it is necessary to push the sliding plate into the frame mounting cavity, and its first mating part needs to pass through the side of the adjacent sliding plate that is already in place, the first guide surface will first contact the edge of the adjacent sliding plate.

[0101] As it continues to be pushed in, the first guide surface, under the action of the contact force, decomposes the pushing force in the pushing direction into a component force perpendicular to the side of the sliding plate. This component force pushes the first mating part to compress the first spring and retract along its channel into the sliding plate (i.e. away from the adjacent sliding plate), thereby achieving avoidance and allowing the sliding plate to be pushed into place smoothly without passing through the pressing part, without being stuck due to the extension of the first mating part.

[0102] The second guide surface is disposed at one end of the first mating part (i.e., the end near the limiting member);

[0103] When the sliding plate is pushed in, the first mating part moves into the channel and at the same time comes into contact with the limiting member. The second guide surface on the first mating part comes into contact with the limiting member. Through the setting of its inclined surface, the force moving towards the channel is partially decomposed into the force that drives the limiting member to avoid it, so that the first mating part can move smoothly into the channel.

[0104] When the first mating part corresponds to the second mating part on the adjacent sliding plate in the channel, the pressing part is reset by the second spring. During the process of the second spring driving the pressing part and the limiting member to reset, the limiting member will contact the second guide surface of the first mating part and slide relative to it.

[0105] Due to the inclined design of the second guide surface, the limiting member will generate a component force on the first mating part. This component force pushes the first mating part to overcome the resistance of the first spring and move outward from the channel (i.e. towards the adjacent second mating part) until the first mating part engages with the adjacent second mating part (e.g., the groove) to achieve locking.

[0106] When unlocking is required, press the pressing part, and the limiting member will move and disengage from the second guide surface, while making room for the first mating part to move into the channel.

[0107] At this moment, the restoring force of the first spring, which has been compressed or stored, is quickly released, driving the first mating part to retract rapidly inward along the channel, thereby unlocking and allowing the sliding plate to be pulled out individually.

[0108] The design of the first and second guide surfaces optimizes the automatic avoidance during the pushing process and the smoothness of the movement of each component during locking / unlocking, making the operation more effortless and reliable.

[0109] Preferably, the frame is provided with slide rails and through grooves;

[0110] At least one threaded hole is provided on the sliding plate at the position corresponding to the through slot;

[0111] The sliding plate is mounted on the slide rail and moves along the fixed trajectory of the slide rail;

[0112] The bolt passes through the through groove and is threaded into the threaded hole to prevent the sliding plate from disengaging from the slide rail.

[0113] The slide rails (such as C-shaped rails, T-shaped rails, etc.) fixed on the frame provide linear movement guidance for the sliding plate;

[0114] The bottom or side of the sliding plate is equipped with a slider structure that matches the slide rail, allowing it to slide smoothly along the slide rail, or as... Figure 2 As shown, rollers are installed on the side of the sliding plate, and corresponding slide rails are installed on the frame at the positions of the rollers, so that the sliding plate can be smoothly pulled out and pushed in on the frame.

[0115] like Figure 2 As shown, the through slot is a long strip-shaped hole opened on the side wall of the frame along the sliding plate's pulling direction.

[0116] Threaded holes are machined on the sliding plate at positions corresponding to the through slots in the frame;

[0117] After the sliding plate is installed onto the slide rail of the frame via its slider structure, bolts are passed through the through slots from the outside of the frame and screwed into the threaded holes of the sliding plate.

[0118] The length of the through groove is parallel to the slide rail, and its length is the same as or longer than the bolt stroke when the sliding plate is fully pulled out or pushed in, ensuring that the bolt can always move freely in the through groove without interference throughout the entire pulling range of the sliding plate.

[0119] The sliding plate can be like Figure 2 As shown, multiple threaded holes are provided. By screwing in bolts, the sliding plate is prevented from detaching from the frame when it is excessively pulled out. The holes can also be set in different positions to correspond to different pull-out or push-in positions of the sliding plate.

[0120] This design improves safety and reliability, while its simple structure and easy installation do not affect normal pull-out maintenance operations.

[0121] Preferably, the frame is provided with positioning holes;

[0122] Positioning elements are provided on the power module at the positions corresponding to the positioning holes;

[0123] The positioning element has threads;

[0124] When the sliding plate pushes the power module in, the positioning component passes through the positioning hole and is threadedly connected to the nut.

[0125] like Figure 4 As shown, one or more positioning holes are provided at the rear of each mounting cavity;

[0126] Accordingly, a positioning element corresponding to the position of the frame positioning hole is installed on the housing of the power module. This positioning element can be a bolt, stud, or guide pin with external threads.

[0127] When the operator pushes the sliding plate with the installed power module into the frame along the slide rail, the positioning piece on the power module will move accordingly. When the sliding plate is pushed into the final working position (i.e. the power module is installed in place), the positioning piece on the power module should be exactly aligned and pass through the corresponding positioning hole on the frame.

[0128] At this point, the nut (or a threaded fastener) can be screwed onto the exposed threaded section of the positioning element from the other side of the mounting cavity and tightened.

[0129] This process first achieves the final positioning of the power module within the frame through the cooperation of the positioning component and the positioning hole, ensuring that the electrical connection terminals and other components can be accurately aligned.

[0130] Secondly, after the nut is threadedly connected to the positioning part, it forms an auxiliary axial fixation for the power module. Combined with the load-bearing capacity of the sliding plate, they jointly resist the vibration and impact force when the power module is working, thus enhancing the stability and reliability of the overall connection.

[0131] A charging pile includes a housing and a module mounting base installed inside the housing;

[0132] The module mounting bracket is as described above;

[0133] The housing is provided with a first receiving compartment for mounting module mounting bases and a second receiving compartment for mounting electronic components;

[0134] The module mounting bracket connects to the electronic components.

[0135] like Figure 5 As shown, the shell constitutes the external protection and support structure of the charging pile;

[0136] The power module can be installed in the module mounting base first, and then the power module can be installed together in the first compartment through the module mounting base, and connected to the electronic components in the second compartment through wires, etc.

[0137] When one or more power modules inside the charging pile need maintenance, repair or replacement, maintenance personnel can open the inspection door or panel of the charging pile housing and directly operate the locking device and sliding plate on the module mounting base.

[0138] Depending on maintenance needs, you can choose to lock adjacent sliding plates to pull out multiple modules synchronously, or unlock them and pull out the target module individually.

[0139] The entire operation process does not require the use of tools to perform complex bolt disassembly and assembly within the narrow internal space of the casing, nor does it require the complete removal of the heavy power module (it only needs to be pulled out to an operable position). This reduces the complexity of maintenance work, physical exertion, and safety risks (such as module detachment and accidental electrical contact), while also shortening maintenance time and improving the operation and maintenance efficiency and availability of the charging pile.

[0140] Preferably, the above description is only a preferred embodiment of the present utility model, and the protection scope of the present utility model is not limited to the above embodiments. All technical solutions within the scope of the present utility model's concept are within the protection scope of the present utility model. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of the present utility model should also be considered within the protection scope of the present utility model.
