Description

Technical Field

[0001] This utility model relates to the field of electronic device mounting structure technology, and in particular to a connecting base. Background Technology

[0002] In the field of electronic equipment mounting structures, the connecting base, as a core connection structure between the equipment and the carrier, directly affects the operational reliability of the equipment due to its mechanical stability and heat dissipation performance. Traditional connecting bases generally suffer from the following defects:

[0003] Structural complexity: The use of independent spring elements to achieve lamp body pre-tensioning results in a large number of parts, complicated assembly process, and the springs are prone to fatigue failure, leading to poor contact.

[0004] Poor heat dissipation: The base and the heat dissipation surface of the device rely on an external heat-conducting medium to transfer heat. After long-term use, the aging of the medium leads to an increase in thermal resistance, which accelerates the temperature rise of the device and causes performance degradation. Utility Model Content

[0005] The main purpose of this utility model is to propose a connecting base that aims to solve the technical problems of complex structure and poor heat dissipation in the existing connecting base.

[0006] To achieve the above objectives, this utility model proposes a connecting base, including a base housing and a heat-conducting plate; the base housing has an axial through groove at its center, and the inner wall of the through groove has a locking part for locking electronic devices; the heat-conducting plate is detachably connected to the base housing by fasteners; the base housing is an integrally formed structure and includes an elastic part, which generates an axial preload through elastic deformation when the electronic device rotates to the locking position of the locking part, so that the heat-conducting bottom surface of the electronic device is tightly attached to the heat-conducting plate.

[0007] Preferably, the elastic part is a mounting bridge, which has mounting holes for the fastener to pass through, and at least one end of the mounting bridge is connected to the base housing body.

[0008] Preferably, both ends of the mounting bridge are fixedly connected to the main body of the base housing, and the middle region of the mounting bridge can elastically bend and deform towards the heat-conducting plate to generate the preload when subjected to the axial pressure of the electronic device; the thickness of the mounting bridge is 0.1 to 0.5 times the thickness of the main body of the base housing.

[0009] Preferably, the mounting bridge is arched, with the arch apex facing away from the direction of the heat-conducting plate.

[0010] Preferably, the deformation path of the mounting bridge is provided with a limiting boss, which is an integral protrusion extending from the base housing body to the mounting bridge. When the elastic deformation of the mounting bridge exceeds the safety threshold, it abuts against the limiting boss to form a mechanical stop.

[0011] Preferably, the number of elastic portions is at least two, and they are distributed at intervals along the circumference of the through groove.

[0012] Preferably, the locking part comprises at least two rotary locking slots.

[0013] Preferably, the rotary locking slot includes an insertion section and a locking section; the insertion section extends axially along the through slot and communicates with the through slot, allowing the electronic device protrusion to be inserted axially; the locking section extends circumferentially from the end of the insertion section, allowing the electronic device protrusion to be rotated and locked.

[0014] Preferably, a locking arm is formed in the side wall region of the locking segment. The locking arm includes a guide portion located at the entrance side of the locking segment and a locking portion located at the end of the locking segment. The guide portion is provided with a guide ramp to reduce the rotational resistance of the electronic device protrusion, and the locking portion is provided with a locking boss to prevent the electronic device protrusion from falling out in the opposite direction.

[0015] Preferably, a separation groove is provided on the radially outer side of the locking arm; the separation groove extends along the root of the locking arm, so that the locking arm forms a cantilever beam structure with the base housing connection end as the fixed fulcrum; when the electronic device protrudes and presses against the locking arm, the locking arm elastically bends and deforms away from the heat conduction plate, thereby enhancing the axial preload on the electronic device.

[0016] This utility model provides a connecting base. Through the one-piece molding design of the base shell and the built-in elastic part, when the electronic device protrudes and rotates to the locking position of the rotary locking slot, the elastic deformation of the elastic part generates an axial preload force, forcing the heat-conducting bottom surface of the electronic device to directly and tightly fit with the detachable heat-conducting plate. This not only replaces the traditional independent spring element with an integrated elastic structure, reducing the number of parts and simplifying the assembly process, eliminating the risk of spring fatigue failure, but also completely solves the problem of increased thermal resistance caused by the aging of external heat-conducting medium through a zero-medium contact heat dissipation method, significantly reducing the LED junction temperature and extending the life of the electronic device. In addition, the rotary locking mechanism of the rotary locking slot and the elastic preload force work together to ensure that the pressure of the heat dissipation interface is adaptively adjusted during installation. Combined with the detachable maintenance design of the heat-conducting plate, it achieves dual optimization of structural complexity and long-term stability while improving heat dissipation efficiency and reliability. Furthermore, this utility model specifically discloses that the elastic part is a mounting bridge structure, which is integrated and fixed with fasteners through mounting holes. Its two ends or one end are connected to the base housing. The middle part undergoes bending deformation under the pressure of electronic equipment to generate a controllable pre-tightening force. The arched design and thickness optimization further improve elastic efficiency and fatigue resistance. The limiting boss restricts overload deformation to protect structural integrity. The circumferential distribution of multiple elastic parts uniformizes the pressure at the heat dissipation interface. Combined with the segmented design of the insertion and locking sections of the rotating locking slot, it achieves rapid installation and physical anti-reverse connection functions. The locking arm reduces operating resistance through a guide slope, and the locking boss prevents disengagement. The cantilever beam structure formed by the separation groove enhances the elastic pre-tightening force. The synergistic effect of these designs simplifies the structure, improves heat dissipation efficiency, ensures installation reliability and long-term stability, and comprehensively optimizes the overall performance of the connecting base.

[0017] In summary, this utility model solves the technical problems of complex structure and poor heat dissipation of the connecting base in the prior art. Attached Figure Description

[0028] The main purpose of this utility model is to propose a connecting base that aims to solve the technical problems of complex structure and poor heat dissipation in the existing connecting base.

[0029] like Figures 1 to 4As shown, a connecting base includes a base housing 1 and a heat-conducting plate 2; the base housing 1 has an axial through groove 11 at its center, and the inner wall of the through groove 11 has a locking part for locking electronic devices; the heat-conducting plate 2 and the base housing 1 are detachably connected by fasteners 3; the base housing 1 is an integrally formed structure and includes an elastic part 13, which generates an axial preload through elastic deformation when the electronic device rotates to the locking position of the locking part, so that the heat-conducting bottom surface of the electronic device is tightly attached to the heat-conducting plate 2.

[0030] For details, please refer to Figures 1 to 3 As shown, in one embodiment of this utility model, a connecting base includes a base housing 1 and a heat-conducting plate 2. The base housing 1 has an axially penetrating through groove 11 at its center, and the inner wall of the groove 11 has a locking part for locking electronic devices. The heat-conducting plate 2 is detachably connected to the base housing 1 by screws 3. The base housing 1 is an integrally formed structure, and an elastic part 13 is provided inside. The working process is as follows: When the protrusion 41 of the electronic device component 4 is inserted into the locking part and rotated to the locked position, the elastic part 13 undergoes elastic deformation under the axial pressure of the electronic device, forming a continuous axial pre-tightening force, which forces the heat-conducting column 42 at the bottom of the electronic device to achieve zero-gap contact with the heat-conducting plate 2. It should be noted that the electronic device component 4 includes, but is not limited to, LED modules, light negative ion generators, sensor modules, power modules, and other electronic devices that need to be fixedly installed and dissipated. Taking the LED module as an example, its bottom is provided with a heat-conducting column 42 and circumferentially distributed protrusions 41. The protrusions 41 cooperate with the locking part to achieve rotational locking. The light negative ion generator can be installed through the same structure, and the heat generated by its ionization module is transferred to the heat-conducting plate 2 for diffusion through the heat-conducting column 42. Other electronic devices only need to be fitted with the protrusion 41 and heat-conducting pillar 42 structure at the bottom to be compatible with the installation and heat dissipation requirements of this connecting base, fully demonstrating its versatility. It is understandable that this utility model uses an integrally molded elastic part 13 to replace independent spring elements, which reduces the number of parts, simplifies the structure, eliminates assembly processes and the risk of spring failure; while the axial preload ensures direct metal-to-metal contact between the heat-conducting bottom surface of the electronic device and the heat-conducting plate 2, resulting in better heat dissipation than traditional heat-conducting medium solutions.

[0031] Preferably, the elastic part 13 is a mounting bridge 131, which has a mounting hole 132 for the fastener 3 to pass through. At least one end of the mounting bridge 131 is connected to the main body of the base housing 1 and generates a preload force through its own elastic bending.

[0032] Specifically, in one embodiment of this utility model, one end of the mounting bridge 131 is fixedly connected to the main body of the base housing 1, while the other end is a free end, thus forming a cantilever beam structure. The fixed end of the mounting bridge 131 is integrally formed with the main body of the base housing 1, and the initial position of the free end maintains a distance from the heat-conducting plate 2. When the electronic device is inserted, the protrusion 41 of the electronic device rotates to the locking position of the rotating locking slot 12. Its gravity and rotational downward pressure act on the free end of the mounting bridge 131, forcing the cantilever beam to bend and deform, generating a continuous axial preload. It can be understood that this embodiment achieves a large deformation through single-end fixing, and the preload adjustment range is wider, making it suitable for the compatibility needs of electronic devices of different sizes.

[0033] Preferably, both ends of the mounting bridge 131 are fixedly connected to the main body of the base housing 1, and the middle area of ​​the mounting bridge 131 can be elastically bent and deformed in the direction of the heat-conducting plate 2 to generate a pre-tightening force when subjected to axial pressure from the electronic device; the thickness of the mounting bridge 131 is 0.1 to 0.5 times the thickness of the main body of the base housing 1.

[0034] For details, please refer to Figure 1 As shown, in one embodiment of this utility model, the two ends of the mounting bridge 131 are fixedly connected to the main body of the base housing 1 through an integral injection molding process, with the central area suspended to form an elastic deformation zone. When the electronic device assembly 4 is inserted into the rotating locking slot 12 and rotated to the locked position, the electronic device heat-conducting column 42 presses down on the central area of ​​the mounting bridge 131, causing it to bend and deform towards the heat-conducting plate 2. The resulting elastic restoring force is converted into axial preload, forcing the heat-conducting bottom surface of the electronic device to fit tightly against the heat-conducting plate 2. The thickness of the mounting bridge 131 is designed to be 0.1 to 0.5 times the thickness of the main body of the base housing 1, ensuring both structural strength and elastic deformation capability. It can be understood that this embodiment achieves the following beneficial effects through the mounting bridge 131 fixed at both ends: concentrated deformation in the central area avoids local fatigue fracture caused by stress dispersion; the fixed structure at both ends allows the deformation amount to be linearly controlled by the downward pressure of the electronic device, and it can be completely reset after the pressure is released.

[0035] Preferably, the mounting bridge 131 is arched, with the top of the arch facing away from the heat-conducting plate 2.

[0036] Specifically, in one embodiment of this utility model, the mounting bridge 131 has an arched structure, with its arch apex facing the opposite direction to the heat-conducting plate 2, i.e., protruding upwards. When the electronic device assembly 4 is inserted into the rotating locking slot 12 and rotated to the locked position, the electronic device heat-conducting column 42 presses down on the arched area of ​​the mounting bridge 131, forcing the arched structure to elastically flatten and deform towards the heat-conducting plate 2. The resulting reverse elastic restoring force forms an axial preload, ensuring that the heat-conducting bottom surface of the electronic device is tightly fitted to the heat-conducting plate 2. The two ends of the arched mounting bridge 131 are integrally connected to the main body of the base housing 1. Its arc design allows the preload to gradually increase during the pressing process of the electronic device until it reaches a stable value when the locking is completed. Understandably, this embodiment utilizes the geometric characteristics of the arched structure to provide progressive deformation under pressure, with the preload increasing steadily with the insertion depth of the electronic device, thus avoiding the impact of sudden stress on the electronic device or the base; the symmetrical force distribution in the arched area reduces local stress concentration and extends the service life of the elastic part 13; after the electronic device is disassembled, the arched mounting bridge 131 can quickly recover its initial shape by relying on its own elasticity, ensuring the reliability of repeated assembly.

[0037] Preferably, the deformation path of the mounting bridge 131 is provided with a limiting boss. The limiting boss is an integral protrusion extending from the main body of the base housing 1 to the mounting bridge 131. When the elastic deformation of the mounting bridge 131 exceeds the safety threshold, it abuts against the limiting boss to form a mechanical stop.

[0038] Specifically, in one embodiment of this utility model, a limiting boss is provided on the deformation path of the mounting bridge 131. The limiting boss is an integral protrusion extending from the main body of the base housing 1 towards the mounting bridge 131, and its end is spaced at a preset distance from the movement trajectory of the mounting bridge 131 after being compressed and deformed. When the electronic device assembly 4 presses down on the mounting bridge 131, the mounting bridge 131 bends and deforms in the direction of the heat guide plate 2. At this time, the limiting boss and the mounting bridge 131 remain in a non-contact state, ensuring that the preload can be freely adjusted. When the deformation of the mounting bridge 131 exceeds the safety threshold due to abnormal external force (such as excessive pressing of the electronic device or assembly error), the compressed part of the mounting bridge 131 abuts against the limiting boss, forming a mechanical stop to avoid plastic deformation or breakage.

[0039] Understandably, this embodiment directly limits the maximum deformation of the mounting bridge 131 through a mechanical stop, preventing the elastic element from failing. The limiting boss is integrally formed with the base housing 1, eliminating the need for additional limiting parts. By adjusting the extension length of the limiting boss, it can be adapted to materials with different elastic moduli or preload requirements. The mechanical stop avoids the deformation threshold drift problem caused by fatigue accumulation in traditional elastic structures. Those skilled in the art can make equivalent improvements based on the above design, such as: designing the contact surface of the limiting boss as a slope or arc to optimize stress distribution; or adding a buffer coating to the contact area between the limiting boss and the mounting bridge 131 to reduce collision noise; or using multi-level limiting bosses to limit different deformation amounts in stages to achieve gradient protection.

[0040] Preferably, the number of elastic portions 13 is at least two, and they are distributed at intervals along the circumferential direction of the through groove 11.

[0041] For details, please refer to Figure 1 As shown, in one embodiment of this utility model, there are two elastic parts 13, evenly spaced along the circumference of the through groove 11. Each elastic part 13 is a mounting bridge 131 structure, with both ends fixedly connected to the main body of the base housing 1. When the protrusion 41 of the electronic device is inserted into the rotating locking slot 12 and rotated to lock, the bottom surface of the electronic device simultaneously presses down on the free ends of the two elastic parts 13, causing them to undergo synchronous elastic deformation and forming a uniform axial preload force around the circumference of the electronic device. Multiple elastic parts 13 are synchronously bent under pressure after the electronic device is locked, and their elastic restoring force is evenly distributed along the circumference of the bottom surface of the electronic device, avoiding local deformation or poor contact caused by excessive pressure at a single point. If the electronic device has a slight assembly tilt, each elastic part 13 can independently adjust the deformation amount, automatically compensating for the angle deviation through differentiated preload force, ensuring full contact between the heat-conducting bottom surface and the heat-conducting plate 2. Understandably, this embodiment uses the synergistic effect of multiple elastic parts to uniformize the pressure at the heat dissipation interface, reduce contact thermal resistance, and improve overall heat dissipation efficiency; the circumferential elastic support enhances the radial positioning stability of the base for electronic devices, preventing rotational loosening caused by vibration or external force; when a single elastic part 13 fails, the remaining elastic parts can still maintain basic preload, improving system reliability; by adjusting the number and distribution density of the elastic parts 13, electronic device components of different sizes or power can be adapted.

[0042] Preferably, the locking part comprises at least two rotary locking slots.

[0043] For details, please refer to Figure 1 and Figure 4In one embodiment of this utility model, the locking part consists of four rotating locking slots 12. It is understood that the multiple locking slots are evenly distributed circumferentially, ensuring that the protrusion of the electronic device experiences balanced force after rotational locking, avoiding displacement or loosening caused by stress concentration on one side, and improving the reliability of mechanical locking. The multiple locking slots cooperate with the deformation of the elastic part 13, ensuring that the axial preload is evenly transmitted circumferentially along the bottom surface of the electronic device, guaranteeing consistent pressure on the contact surface between the heat-conducting plate 2 and the electronic device, and reducing local thermal resistance.

[0044] Preferably, the rotary locking slot 12 includes an insertion section 12a and a locking section 12b; the insertion section 12a extends axially along the through slot 11 and communicates with the through slot 11, allowing the electronic device protrusion to be inserted axially; the locking section 12b extends circumferentially from the end of the insertion section 12a, allowing the electronic device protrusion to be rotated and locked.

[0045] For details, please refer to Figure 1 and Figure 4 As shown, in one embodiment of this utility model, the rotating locking slot 12 includes an insertion section 12a and a locking section 12b. The insertion section 12a extends axially along the through slot 11 and communicates with the through slot 11, allowing the electronic device protrusion 41 to be inserted axially; the locking section 12b extends circumferentially from the end of the insertion section 12a, forming an arc-shaped channel for the electronic device protrusion 41 to be rotated and locked. When the electronic device protrusion 41 slides from the insertion section 12a into the locking section 12b and rotates to its end, the elastic part 13 of the base housing 1 is compressed and deformed, generating an axial preload. It can be understood that this embodiment achieves the following beneficial effects through the segmented structure of the insertion section and the locking section: axial insertion ensures the initial positioning of the electronic device, and circumferential rotation locking avoids misoperation; the user only needs two steps, "insertion-rotation," to complete the installation without additional fixing operations, which simplifies the assembly process. Those skilled in the art can make equivalent improvements based on the above design, such as: designing the locking section 12b as a zigzag or sawtooth channel to provide multiple locking positions; or setting a transition slope / rounded corner between the insertion section 12a and the locking section 12b to reduce rotational resistance.

[0046] Preferably, a locking arm 121 is formed in the side wall region of the locking segment 12b. The locking arm 121 includes a guide portion 1211 located at the entrance side of the locking segment 12b and a locking portion 1212 located at the end of the locking segment 12b. The guide portion 1211 is provided with a guide ramp to reduce the rotational resistance of the electronic device protrusion, and the locking portion 1212 is provided with a locking boss to prevent the electronic device protrusion from falling out in the opposite direction.

[0047] For details, please refer to Figure 1 and Figure 4As shown, in one embodiment of this utility model, the guide portion 1211 is provided with a guide slope to guide the electronic device protrusion 41 to smoothly transition to the locking section 12b; the locking portion 1212 is provided with a locking boss, the height of which is slightly higher than the bottom of the groove in the locking section 12b. When the electronic device protrusion 41 rotates to the locking portion 1212, the locking boss forms a mechanical locking point to prevent it from disengaging in the opposite direction. It can be understood that this embodiment reduces rotational resistance and improves user experience through the guide slope; the locking arm 121 is integrally formed with the base housing 1 to avoid failure caused by wear of independent parts and extend the life of the base.

[0048] Preferably, a separation groove 122 is provided on the radial outer side of the locking arm 121; the separation groove 122 extends along the root of the locking arm 121, so that the locking arm 121 forms a cantilever beam structure with the connecting end of the base housing 1 as the fixed fulcrum; when the electronic device protrudes and presses against the locking arm 121, the locking arm 121 elastically bends and deforms away from the heat conduction plate 2, thereby enhancing the axial preload on the electronic device.

[0049] Understandably, this embodiment achieves the following beneficial effects through the design of the separation groove 122: the stress of the cantilever beam structure is concentrated at the root, generating high preload with minimal deformation, reducing the risk of material fatigue; the separation groove 122 is achieved through an integral molding process, eliminating the need for additional processing of elastic elements; the bending direction of the locking arm 121 is away from the heat-conducting plate 2, cooperating with the gravity direction of the electronic device to superimpose and form a greater clamping force.

[0050] This utility model provides a connecting base. Through the one-piece molding design of the base shell and the built-in elastic part, when the electronic device protrudes and rotates to the locking position of the rotary locking slot, the elastic deformation of the elastic part generates an axial preload force, forcing the heat-conducting bottom surface of the electronic device to directly and tightly fit with the detachable heat-conducting plate. This not only replaces the traditional independent spring element with an integrated elastic structure, reducing the number of parts and simplifying the assembly process, eliminating the risk of spring fatigue failure, but also completely solves the problem of increased thermal resistance caused by the aging of external heat-conducting medium through a zero-medium contact heat dissipation method, significantly reducing the LED junction temperature and extending the life of the electronic device. In addition, the rotary locking mechanism of the rotary locking slot and the elastic preload force work together to ensure that the pressure of the heat dissipation interface is adaptively adjusted during installation. Combined with the detachable maintenance design of the heat-conducting plate, it achieves dual optimization of structural complexity and long-term stability while improving heat dissipation efficiency and reliability. Furthermore, this utility model specifically discloses that the elastic part is a mounting bridge structure, which is integrated and fixed with fasteners through mounting holes. Its two ends or one end are connected to the base housing. The middle part is subjected to bending deformation under the pressure of electronic equipment to generate a controllable pre-tightening force. The arched design and thickness optimization further improve elastic efficiency and fatigue resistance. The limiting boss limits overload deformation to protect structural integrity. The circumferential distribution of multiple elastic parts makes the pressure of the heat dissipation interface uniform. Combined with the segmented design of the insertion section and locking section of the rotary locking slot, it realizes quick installation and physical anti-reverse connection function. The locking arm reduces the operating resistance through the guide slope, and the locking boss prevents it from falling out. The cantilever beam structure formed by the separation groove enhances the elastic pre-tightening force, and the asymmetrically distributed rotary locking slot forces the electronic equipment to be installed only in the preset position through physical limitation, avoiding the risk of electrode reverse connection. The above design works synergistically to simplify the structure, improve heat dissipation efficiency, ensure installation reliability and long-term use stability, and comprehensively optimize the overall performance of the connection base.

[0051] In summary, this utility model solves the technical problems of complex structure and poor heat dissipation of the connecting base in the prior art.
