Description

Technical Field

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] The purpose of the present invention is to provide a hot-swap system to solve the technical problem that the existing hot-swap system is difficult to achieve connection stability while ensuring plug-in efficiency.

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] like Figure 1-Figure 3As shown, the present invention provides a hot-swap system 100, including a housing 1, a connector fixing frame 4, a first module slide rail 2, a first locking element 3 and a power module frame 6, one side of the housing 1 is open, and the power module frame 6 can be plugged in and out through the opening, the connector fixing frame 4 is fixed in the housing 1, and the connector fixing frame 4 is used to fix the connector 5, the first module slide rail 2 is fixed on the inner side wall of the housing 1, and the power module frame 6 is slidably connected to the first module slide rail 2, and the power module frame 6 can slide into or out of the first module slide rail 2 through the opening, ensuring that the power module frame 6 is plugged in and out during The power module frame 6 is used to install the power supply, and the power module frame 6 can drive the power supply to move to be electrically connected with the connector 5. The first locking element 3 can lock the power module frame 6 on the first module slide rail 2 and keep the power supply in the power module frame 6 electrically connected with the connector 5, thereby ensuring the clamping of the power module frame 6 and the stability of its connection, avoiding the power module frame 6 from falling off during vibration, and locking with the first locking element 3 can relax the design size of the first module slide rail 2, so as to improve the plugging efficiency.

[0029] Specifically, Figure 4As shown, the first locking element 3 includes a base 31, and the base 31 is used to be clamped on one side of the power module frame 6 close to the opening, so as to facilitate the limitation of the power module frame 6, and the power module frame 6 is clamped between the base 31 and the side wall of the shell 1, and a fastening installation hole 34, a fixing hole 32 and a module limiting groove 33 are provided on the base 31, and the side wall where the first module slide rail 2 is located is the contact side wall 11, and the module limiting groove 33 is provided on the base 31. One end of the power module frame 6 is close to the power module frame 6, and the module limiting groove 33 passes through the base 31 in a direction perpendicular to the contact side wall 11, and the opening of the module limiting groove 33 faces the power module frame 6, so that the base 31 and the power module frame 6 are clamped together through the module limiting groove 33, and a clamping portion 65 is provided on the power module frame 6, and the clamping portion 65 can extend into the module limiting groove 33 and clamped with the module limiting groove 33, and more preferably, through The friction between the clamping portion 65 and the inner wall of the module limiting groove 33 realizes clamping to improve the stability of the connection. The fixing hole 32 passes through the base 31 in the direction of contacting the side wall 11, and the first locking element 3 is connected to the shell 1 by passing the bolt through the fixing hole 32 and the side wall of the shell 1, thereby ensuring that the position of the base 31 is fixed after being installed in place to prevent it from falling off during vibration and affecting the limitation and clamping of the power module frame 6; the fastening installation hole 34 passes through the base 31 in a direction parallel to the first module slide rail 2, and the fastening installation hole 34 is connected to the first module slide rail 2 by passing the bolt through the fastening installation hole 34 and threadedly connected with one end of the first module slide rail 2. More preferably, a threaded hole is provided on the end of the first module slide rail 2 close to the base 31, and the bolt is passed through the fastening installation hole 34 and connected to the threaded hole, which can better ensure the fixation of the position of the base 31.

[0030] The distance between the two opposite side walls on the module limiting groove 33 gradually decreases from the opening of the module limiting groove 33 to the inner bottom surface of the module limiting groove 33, that is, when in use, the side walls of the module limiting groove 33 are inclined to ensure that during the process of connecting the module limiting groove 33 with the clamping portion 65, as the clamping portion 65 gradually extends into the module limiting groove 33, the clamping portion 65 and the module limiting groove 33 are gradually clamped, so as to ensure that the power module frame 6 is limited and fixed by the base 31, and will not affect the plug-in efficiency of the power module frame 6.

[0031] The inner bottom surface of the module limiting groove 33 is also provided with two avoidance grooves 35, which are respectively opened at the connection between the inner wall of the module limiting groove 33 and the inner bottom surface of the module limiting groove 33, that is, located at the upper and lower ends of the inner bottom surface of the module limiting groove 33, and the avoidance groove 35 protrudes from the inner bottom surface of the module limiting groove 33, and the inner wall of the avoidance groove 35 is an arc surface, and the avoidance groove 35 is an arc angle formed in the process of milling. In the actual installation process, the avoidance groove 35 will never contact the clamping part 65. In the process of connecting the base 31 with the power module frame 6, as the screw is screwed in, the base 31 is driven to gradually move closer to the power module frame 6 until the inner side wall of the module limiting groove 33 and the upper and lower end surfaces of the clamping part 65 are clamped until the base 31 cannot move, thereby ensuring that the power module frame 6 is stuck. At this time, a screw is passed through the fixing hole 32 and fixed to the side wall of the shell 1, that is, installed in place, to achieve stable fixation of the base 31.

[0032] The fixing hole 32 is a long hole, and the length direction of the fixing hole 32 is parallel to the first module slide rail 2, so that the position of the base 31 can be changed by passing the bolts through different positions of the fixing hole 32 and threadedly connected with the threaded holes on the side wall of the shell 1 to adapt to power module frames 6 of different sizes.

[0033] like Figure 1-Figure 3 As shown, the upper end of the connector fixing frame 4 is fixed to the inner top surface of the shell 1, the lower end of the connector fixing frame 4 is fixed to the inner bottom surface of the shell 1, and one side of the connector fixing frame 4 is fixed to the inner side wall of the shell 1, so that the connector fixing frame 4 is fixed at the outer periphery of the connector fixing frame 4, thereby improving the overall strength of the connector fixing frame 4 and preventing the stability of the installation of the connector fixing frame 4 and the shell 1 from being destroyed during multiple plugging and unplugging processes.

[0034] A plurality of exhaust fans 8 are installed on the side wall of the housing 1 adjacent to the contact side wall 11. When in use, air enters from the opening side of the housing 1, passes through the heat sink 63 on the power module frame 6, and is finally drawn out through the exhaust fan 8, thereby taking away the heat in the housing 1. A windshield 7 is also fixed in the housing 1. The windshield 7 is parallel to the side wall where the first module slide rail 2 is located, and the windshield 7 is parallel to the contact side wall 11. The upper end of the windshield 7 is fixed to the inner top surface of the housing 1, and the lower end of the windshield 7 is fixed to the inner bottom surface of the housing 1. One side of the wind shield 7 is fixed on the side wall of the shell 1 adjacent to the contact side wall 11, and the power module frame 6 is located between the contact side wall 11 and the wind shield 7. Since the radiator 63 is only arranged on the power module frame 6, the wind shield 7 and the contact side wall 11 are used to limit the position to prevent the wind from reaching the gap between the side wall of the shell 1 opposite to the contact side wall 11 and the wind shield 7. The radiator 63 is not arranged in this gap, so the wind entering this gap cannot carry heat and discharge it, thereby improving the utilization rate of wind energy.

[0035] A plurality of second module slide rails are provided on one side of the wind shield 7 close to the power module frame 6, one first module slide rail 2 corresponds to one second module slide rail, and the positions of the first module slide rail 2 and the second module slide rail correspond, that is, they are arranged in parallel and are equal to the inner bottom surface of the shell 1. The side of the power module frame 6 away from the first module slide rail 2 is slidably connected to the second module slide rail. Through the cooperation of the first module slide rail 2 and the second module slide rail, the power module frame 6 is limited and its stable sliding is guaranteed to achieve plugging and unplugging.

[0036] The hot-swap system 100 provided by the present invention also includes a second locking element, which has the same structure as the first locking element 3, and the second locking element can lock the power module frame 6 on the second module slide rail and keep the power supply in the power module frame 6 electrically connected to the connector 5. The anti-vibration property of the second locking element is the same as that of the first locking element 3, thereby ensuring the stability of the power module frame 6 during insertion and preventing automatic unplugging during vibration, thereby affecting normal operation.

[0037] like Figure 5 As shown, the power module frame 6 includes a protective shell 61, a heat sink 63 and a handle 62. The protective shell 61 is used to install a power supply. A handle 62 is fixed on one side of the protective shell 61. The handle 62 is used for the user to hold, and the handle 62 is located on the side of the power module frame 6 close to the opening of the shell 1, so that the user can directly push the power module frame 6 into the shell 1 or pull it out of the shell 1 by holding the handle 62, which is convenient for plugging and unplugging. The heat sink 63 is fixed at the lower end of the protective shell 61, and a plurality of slide bars 64 are also fixed on the outer wall of the protective shell 61. The slide bar 64 can be slidably connected with the first module slide rail 2 to ensure stability during plugging and unplugging; more preferably, the number of the first module slide rail 2 and the second module slide rail can be set to multiple, so as to facilitate the plugging and unplugging and fixing of multiple power module frames 6.

The above examples are only used to help understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation methods and application scope.
