Description

Technical Field

[0001] The utility model belongs to the technical field of electric vehicles, and in particular relates to an adaptive plug-in structure of a discharge plug of an electric motorcycle. Background Art

[0002] In order to promote energy conservation, emission reduction and environmental protection, major cities are now beginning to advocate the use of electric vehicles, such as electric buses, electric cars and electric motorcycles. Electric motorcycles are currently one of the most convenient electric vehicles for personal travel. To facilitate the removal of electric motorcycle batteries, most electric motorcycles are equipped with a battery holder with an upward opening at the position corresponding to the fuel tank of a fuel motorcycle or under the seat. The battery is placed vertically in the battery holder and fixed by a cover or seat cushion. The output interface of the battery is generally set at the top of the battery along with the charging port. When removing and placing the battery, it is necessary to manually unplug and plug the connector to disconnect and connect the battery and the electric motorcycle, which is inconvenient to use.

[0003] In order to reduce the difficulty of taking and putting batteries and improve the user experience, such as the novel series-parallel battery connection barrel disclosed in Chinese patent CN213184497U and the quick connection mechanism of the built-in battery of electric bicycle and electric motorcycle disclosed in Chinese patent CN203063645U, a plug-in base is arranged at the bottom of the battery barrel, and a socket spring is arranged on the plug-in base. Correspondingly, a plug-in piece adapted to the socket spring is arranged at the bottom of the battery to form a discharge plug adapted to the plug-in base, which replaces the output interface on the top of the original battery; when the battery is placed in the battery barrel, the inner side wall of the battery barrel limits the battery position to play a plug-in positioning role, so that the plug-in piece of the discharge plug faces the socket spring on the plug-in base and plugs in and cooperates, so as to realize the electrical connection between the battery and the electric motorcycle. When taking out the battery, the battery is normally lifted up, and the plug-in piece is immediately separated from the socket spring to disconnect the electrical connection, eliminating the operation of manually unplugging and plugging the connector, making it more convenient to take and put the battery. However, due to the influence of manufacturing, assembly accuracy and wear and tear during use, position deviations are inevitable between the discharge plug and the socket base, resulting in the inability of the plug and the socket spring to align completely, especially in the direction perpendicular to the plug. As a result, when the battery is inserted, the plug may not be able to be plugged into the socket spring. Even if they are successfully plugged into each other, the two tend to move relative to each other in the direction perpendicular to the plug, which not only easily causes deformation and damage to the plug and the socket spring, but also increases the friction between the plug and the socket spring, making it more difficult to disengage the two when removing the battery. Therefore, further optimization is needed. Summary of the invention

[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0025] Example:

[0026] See also Figure 1 and Figure 3 , an adaptive plug-in structure of an electric motorcycle discharge plug, comprising a receiving cavity arranged at the bottom of a battery 1 of the electric motorcycle, an opening 2 communicating with the receiving cavity is opened on the bottom surface of the battery 1, a connecting seat 3 is movably arranged in the receiving cavity, a plurality of plug-ins 4 are vertically embedded on one side of the connecting seat 3 facing the opening 2, the plurality of plug-ins 4 are located in the opening 2 and are arranged in parallel and spaced apart, in a direction perpendicular to the plug-ins 4 (the direction in which the plug-ins 4 are spaced apart), there are spacings between the two side walls of the opening 2 and the adjacent plug-ins 4, and between the two side walls of the receiving cavity and the connecting seat 3, so that the connecting seat 3 can float left and right in a direction perpendicular to the plug-ins 4, the plug-ins 4 can adaptively move when subjected to force, and overcome the position deviation of the plug-in, the plug-ins 4 are electrically connected to the cells in the battery 1 and do not interfere with the adaptive movement.

[0027] During implementation, the specific size of the distance between the two side walls of the accommodating cavity and the connecting seat 3 is preferably used to determine the specific travel of the left and right floating amount of the connecting seat 3 in the direction perpendicular to the plug-in 4. The two side walls of the opening 2 and the adjacent plug-in 4 have a larger distance to prevent interference, that is, the distance between the two side walls of the opening 2 and the adjacent plug-in 4 is greater than the distance between the two side walls of the accommodating cavity and the connecting seat 3. When in use, the plug-in 2 is usually plugged in and electrically connected with a fixed socket jack or socket spring. The socket jack or socket spring has the necessary plug-in adaptation width in the direction perpendicular to the plug-in 4. The left and right floating amount of the connecting seat 3 does not exceed the plug-in adaptation width to ensure the prerequisite for adaptive deviation correction (can be plugged in oppositely). It is sufficient to make a reasonable process assignment of the spacing in combination with the actual size without specific restrictions.

[0028] In this embodiment, the opening 2 and the plug 4 in the opening 2 form a discharge plug of the battery 1. In order to achieve plug-in matching, a plug-in base 5 is correspondingly provided at the bottom of the battery holder barrel of the electric motorcycle. The position of the discharge plug on the bottom surface of the battery 1 is adapted to the position of the plug-in base 5 at the bottom of the battery holder barrel. A plurality of socket springs 6 are embedded on the plug-in base 5. The plurality of socket springs 6 correspond to the plurality of plugs 4 one by one. The mouth of the socket spring 6 for plug-in matching is V-shaped to play a guiding role during plugging. The common socket spring 6 is adopted in this embodiment. At the same time, the possible left and right shaking amount of the battery 1 in the battery holder barrel is considered (the shaking amount is small because the inner wall of the battery holder barrel limits the position of the battery 1). Correspondingly, the spacing between the two side walls of the accommodating cavity and the connecting seat 3 is reasonably assigned a process value, so that when the battery 1 in the battery holder barrel and the connecting seat 3 in the accommodating cavity are offset to the same side, the plug 4 can still fall within the guiding width of the V-shaped mouth of the socket spring 5; at least, the left and right floating amount of the connecting seat 3 should not be greater than the socket spring 5. The width of the V-shaped mouth (i.e. the aforementioned plug-in adaptation width).

[0029] The adaptive plug-in structure of the electric motorcycle discharge plug of the utility model is provided with a receiving cavity at the bottom of the battery 1, and the connecting seat 3 with the plug 4 is movably arranged in the receiving cavity and limited in a direction perpendicular to the plug 4. A certain distance is left between the connecting seat 3 and the side wall of the receiving cavity, so that the plug 4 is in an active state at the bottom of the battery 1 that can move in a direction perpendicular to the plug 4; when the battery 1 is vertically placed in the battery seat barrel, as shown in FIG. Figure 4 As shown, if the discharge plug is facing the plug base 5, the plug 4 moves down with the battery 1 and plugs into the socket spring 6; Figure 5 As shown, if there is a position deviation between the discharge plug and the plug-in base 5, and the plug-in piece 4 is not completely aligned with the socket spring piece 6, after the plug-in piece 4 and the socket spring piece 6 are in contact at the V-shaped mouth, since the socket spring piece 6 is fixed, as the plug-in piece 4 moves downward, the plug-in piece 4 and the connecting seat 3 connected thereto will move under the guidance of the inclined surface of the mouth of the socket spring piece 6 until the plug-in piece 4 and the socket spring piece 6 are completely aligned; at this time, although there is a position deviation between the discharge plug and the plug-in base 5, the plug-in piece 4 in the discharge plug and the socket spring piece 6 of the plug-in base 5 are aligned and plugged in, and the plug-in piece 4 and the socket spring piece 6 have no tendency to move relative to each other in the direction perpendicular to the plug-in piece 4, which will not cause deformation or damage to the plug-in piece 4 and it is easier to disengage the two when taking out the battery 1;

[0030] The adaptive plug-in structure of the discharge plug of the electric motorcycle described in the utility model has a connection seat 3 movably connected to the bottom of the battery 1, which can adaptively move when the plug-in piece 4 is subjected to force, thereby overcoming the position deviation when the battery 1 is inserted, and can effectively solve the problem that the discharge plug of the electric motorcycle battery 1 and the plug-in base 5 in the battery holder barrel are difficult to plug in due to position deviation, which is conducive to reducing the difficulty of taking and placing the battery, improving the user experience and product competitiveness.

[0031] See also Figure 2 and Figure 3 , the plug 4, as a contact of the discharge plug of the battery 1, needs to be electrically connected to the battery cell inside the battery 1. In order to prevent the electrical connection between the plug 4 and the battery cell from affecting the movement of the connecting seat 3, during implementation, an elastic plug pin electrically connected to the battery cell can be provided at the bottom of the accommodating groove 8, and a metal sheet extending in a direction perpendicular to the plug 4 is provided at the bottom of the connecting seat 3. The metal sheet partially extends into the connecting seat 3 and is electrically connected to the plug 4, so that the plug 4 always remains electrically connected to the battery cell during the movement of the connecting seat 3; however, the reliability of achieving electrical connection by abutting the elastic plug pin with the metal sheet is poor, and it may fail under vibration and is easy to wear; therefore, in this embodiment, a flexible cable 7 is connected between the connecting seat 3 and a side wall of the accommodating cavity in a direction parallel to the plug 4 to avoid interference with the adaptive movement, one end of the cable 7 is fixedly inserted into the battery 1 to be electrically connected to the core of the battery 1, and the other end is fixedly inserted into the connecting seat 3 to be electrically connected to the plug 4; in this way, the flexible cable 7 can swing with the connecting seat 3, the hindrance to the movement of the connecting seat 3 is small, and the line connection is stable and reliable.

[0032] See also Figure 1 and Figure 3 The edge of the opening 2 and the bottom surface of the battery 1 are chamfered; in this way, the side wall of the opening 2 is inclined, and when the battery 1 is inserted, it cooperates with the socket spring 6 to play a preliminary guiding role, ensuring that the plug 4 falls to the inside of its mouth when it approaches the socket spring 6.

[0033] See also Figure 3 In the height direction of the battery 1, the size of the connecting seat 3 is adapted to the size of the accommodating cavity; in this way, the vertical movement of the connecting seat 3 is restricted to ensure that the plug 4 can be plugged and matched with the corresponding socket spring 6.

[0034] For ease of assembly, see Figure 1 and Figure 2 A receiving groove 8 is provided on the bottom surface of the battery 1 , a cover plate 9 is provided in the receiving groove 8 , the inner side surface of the cover plate 9 and the receiving groove 8 form the receiving cavity, and the opening 2 is provided on the cover plate 9 .

[0035] In order to prevent the connection base 3 from moving in a direction parallel to the plug 4 and affecting the plug-in cooperation between the plug 4 and the socket spring 6, a protrusion can be provided at the bottom of the accommodating groove 8 or the inner side of the cover plate 9 to limit the connection base 3. Figure 1 and Figure 2In this embodiment, the bottom of the accommodating groove 8 protrudes outward to form four connecting columns 10, the inner side surface of the cover plate 9 abuts against the end surface of the connecting column 10, and the cover plate 9 is connected to the connecting column 10 by a penetrating screw 11. The four connecting columns 10 are grouped in pairs, and the connecting seat 3 is located between the two groups of connecting columns 10 in a direction parallel to the plug 4, and the size of the connecting seat 3 is adapted to the spacing between the two groups of connecting columns 10; in this way, the support, connection cover plate 9 and restriction of the connection seat 3 moving on the connecting column 10 in a direction parallel to the plug 4 are integrated to make the structure simpler.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the technical solution. Ordinary technicians in this field should understand that those modifications or equivalent replacements of the technical solution of the utility model without departing from the purpose and scope of the technical solution of the utility model should be included in the scope of the claims of the utility model.
