[0022] First, it should be noted that the orientation words such as up, down, left, right, front, and back in the present invention are only described according to the drawings for the convenience of understanding, and do not limit the technical solution and the scope of the claimed protection of the present invention.
[0023] Such as Figures 1 to 4The specific implementation of a cable anti - detachment device for an electric drive chassis equipment according to the present invention is shown. A plurality of connector sockets 11 are provided at the front end of the equipment 1, and the plurality of connector sockets 11 are respectively connected to a plurality of cables 13 through connector plugs 12. The left bracket 2 and the right bracket 3 are fixedly arranged corresponding to the left and right sides of the equipment 1. The lower support plate 4 is fixed between the left bracket 2 and the right bracket 3, and the detachable upper pressure plate 5 is fixed on the lower support plate 4, so that the plurality of cables 13 are respectively clamped between the lower support plate 4 and the upper pressure plate 5. Through the above structural arrangement, a cable anti - detachment device for an electric drive chassis equipment with simple structure, low cost, good anti - detachment effect, safety and reliability is formed. By setting the left bracket 2 and the right bracket 3, the present invention can play a stable supporting role for the lower support plate 4 and the upper pressure plate 5. Through the clamping of the lower support plate 4 and the upper pressure plate 5 on the cable 13, the stable and reliable insertion of the connector plug 12 and the connector socket 11 is ensured, and the problem that the connector is loosened or detached due to vibration and pulling during the vehicle driving process is solved, improving the safety of the vehicle and personnel; by adopting a detachable fixing method between the upper pressure plate 5 and the lower support plate 4, the convenience of disassembly, installation and maintenance is improved. It should be noted that the above - mentioned equipment refers to the electrical equipment arranged on the electric drive chassis. In practical applications, the present invention makes the lower support plate 4 and the upper pressure plate 5 made of insulating materials to improve safety. The insulating materials can adopt various forms such as epoxy resin plates and bakelite, and a three - proof paint is sprayed on the surfaces of the lower support plate 4 and the upper pressure plate 5 to improve the anti - mildew, anti - moisture and anti - salt - fog properties. On the basis of ensuring the stable and reliable clamping, in order to reduce the weight, the width of the lower support plate 4 and the upper pressure plate 5 is usually set to 25 - 30 mm, and the distance from the lower support plate 4 and the upper pressure plate 5 to the end of the connector plug 12 is set to 100 - 120 mm according to the thickness of the cable 13.
[0024] As an optimized solution, in this specific implementation, lower arc grooves 41 are respectively arranged at the positions corresponding to the plurality of cables 13 on the lower support plate 4, and the left and right ends of the arc surface of the lower arc groove 41 are smoothly transitioned with the upper side surface of the lower support plate 4 through lower rounded corners 42. Similarly, upper arc grooves 51 are respectively arranged at the positions corresponding to the plurality of cables 13 on the upper pressure plate 5, and the left and right ends of the arc surface of the upper arc groove 51 are smoothly transitioned with the lower side surface of the upper pressure plate 5 through upper rounded corners 52. This structural arrangement can play an effective limiting role on the cable 13 through the clamping hole positions formed by the cooperation of the lower arc groove 41 and the upper arc groove 51, which is beneficial to arranging the cables 13 in order and improving the stable and reliable clamping; by setting the lower rounded corners 42 and the upper rounded corners 52, it can prevent the sharp edges from damaging the cable, effectively avoiding electric leakage and fire, and enhancing the safety and reliability.
[0025] As a specific implementation manner, the left bracket 2 and the right bracket 3 of the present invention are configured as follows: a left connecting plate 21 fixed to the left side of the device 1 is provided on the left bracket 2, a left column 22 is vertically fixed to the front end of the left connecting plate 21, and a left ear plate 23 for mounting the lower support plate 4 is provided on the right side of the left column 22; a right connecting plate 31 fixed to the right side of the device 1 is provided on the right bracket 3, a right column 32 is vertically fixed to the front end of the right connecting plate 31, and a right ear plate 33 for mounting the lower support plate 4 is provided on the left side of the right column 32. The left bracket 2 and the right bracket 3 thus arranged have the characteristics of simple structure, easy manufacturing, and convenient disassembly and assembly. In practical applications, in order to facilitate installation and fixation, mounting seats 14 distributed at intervals are usually provided on the left and right sides of the device 1 in the art. The present invention makes full use of the mounting seats 14 of the device 1 to simplify the structure and installation process, and the left connecting plate 21 and the right connecting plate 31 are respectively fixed to the mounting seats 14 on the left and right sides of the device 1 by screws.
[0026] Since the device 1 has a large number of external interfaces, in order to standardize the interface design and ensure the convenience of connection operations in the art, multiple connector sockets 11 on the device 1 are usually divided into multiple layers distributed vertically, and correspondingly, the connector plugs 12 and the cables 13 are also divided into multiple layers from bottom to top. To adapt to this multi-layer structure, the present invention provides multiple groups of lower support plates 4 and upper pressure plates 5 corresponding to each other from bottom to top according to the number of layers of the cables 13, and the cables 13 of the same layer are clamped between the corresponding lower support plates 4 and upper pressure plates 5. This arrangement makes the lower support plates 4 and the upper pressure plates 5 of each layer form an independent clamping structure, and the cables of each layer can be disassembled and assembled separately without affecting the connection stability of the cables of other layers. It should be noted that the above external interfaces, interfaces should be understood as the same concept as the connector sockets. At the same time, the present invention provides multiple left ear plates 23 and right ear plates 33 corresponding to each other from bottom to top according to the number of lower support plates 4, and both ends of the lower support plate 4 are respectively fixed to the corresponding left ear plates 23 and right ear plates 33 by screws.
[0027] As a detachable fixing method between the upper pressing plate 5 and the lower supporting plate 4, in this specific embodiment, left and right distributed binding limiting grooves are provided on the lower supporting plate 4 and the upper pressing plate 5, and the upper pressing plate 5 and the lower supporting plate 4 are fixed by a cable tie 6 placed in the binding limiting grooves. Fixing with the cable tie 6 can reduce the requirement for the operating space and has a relatively low cost; by providing the binding limiting grooves, the operator can accurately and quickly find the binding position, which is beneficial to improving the disassembly and assembly efficiency. To ensure the reliability of the binding fixation, the present invention generally also provides an arc chamfer for the binding limiting grooves to improve the tightness of the cable tie 6 being tightened. It should be noted that the detachable fixing method between the upper pressing plate 5 and the lower supporting plate 4 is not limited to the above-listed structures, and the following structure can also be adopted: left and right distributed threaded sleeves are embedded on the lower supporting plate 4, through holes corresponding to the threaded sleeves are provided on the upper pressing plate 5, and the upper pressing plate 5 and the lower supporting plate 4 are fixed by screws passing through the through holes and being screwed into the threaded sleeves, which can also achieve the technical purpose of the present invention.
[0028] Based on the same concept, the present invention also provides an installation method for the anti-disconnection device of the connection cable of the electric drive chassis equipment, which specifically includes the following steps:
[0029] S1. Fix the left bracket 2 and the right bracket 3 together with the equipment 1 on the electric drive chassis by screws, wherein the left bracket 2 and the right bracket 3 are correspondingly located on the left and right sides of the equipment 1.
[0030] S2. According to the number of layers of the cable 13, install the lower supporting plates 4, the cables 13, and the upper pressing plates 5 of each layer in sequence from the bottom layer upwards; wherein, both ends of the lower supporting plate 4 are correspondingly fixed on the left ear plate 23 of the left bracket 2 and the right ear plate 33 of the right bracket 3 by screws, the cable 13 is plugged into the connector socket 11 through the connector plug 12, and the upper pressing plate 5 is fixed on the lower supporting plate 4 by the cable tie 6.
[0031] The installation method for the anti-disconnection device of the connection cable of the electric drive chassis equipment provided by the present invention has the characteristics of simple operation, high working efficiency, and safety and reliability.
