Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of power batteries, and in particular to a guide connector, a guide plug, a guide matching kit and a battery pack. BACKGROUND

[0002] In a conventional two-wheeled electric vehicle, a battery pack is usually installed in a vehicle body fixing seat and connected with a male connector and a female connector for power supply and communication. For example, a battery charging and discharging connector is disclosed in Chinese Patent Document CN210167595U. However, since the battery pack and the vehicle body fixing seat are separate, and the male plug and the female seat of the male connector and the female connector are respectively installed on the vehicle body fixing seat and the battery pack, when the two-wheeled electric vehicle is running and jolts, the battery pack and the vehicle body fixing seat are prone to relative shaking. At this time, the guide structure between the male plug and the female seat is prone to loosening, which eventually leads to poor contact or open circuit. CONTENT OF THE UTILITY MODEL

[0003] The purpose of the present disclosure is to overcome the deficiencies in the prior art and provide a guide connector, a guide plug, a guide matching kit and a battery pack that can be stably connected when jolting and take into account waterproof and dustproof performance.

[0008] a first guide connector movably provided in the fitting opening, the first guide connector having an elastic fitting structure, and the first pre-tightening sealing structure being sealingly fitted to the elastic fitting structure, so that the first guide connector shakes with a second guide connector on the vehicle body fixing seat when the first guide connector is inserted and matched with the second guide connector.

[0009] In some embodiments, the first pre-tightening sealing structure has a connected elastic body and a locking part, the elastic body is sealingly abutted to the first guide connector, and the locking part is snap-fitted to the outer peripheral wall of the first guide connector.

[0010] In some embodiments, the elastic body is arranged around the first guide connector, a contraction clamping cavity is formed in the elastic body, and part of the first guide connector is accommodated in the contraction clamping cavity and abutted to the cavity wall of the contraction clamping cavity.

[0011] In some embodiments, the elastic body comprises at least two elastic clamping pieces arranged in sequence along the circumference of the first connector seat, and a micro-motion gap is formed between adjacent elastic clamping pieces.

[0012] In some embodiments, a limiting groove is formed on the outer circumferential wall of the first connector seat, and the locking portion is embedded in the limiting groove.

[0013] A connector plug, comprising:

[0014] A vehicle body fixing seat for mounting on a two-wheeled electric vehicle; an installation opening is formed on the vehicle body fixing seat;

[0015] A second pre-tightening sealing structure is provided at the installation opening and fixedly connected to the vehicle body fixing seat; the inner diameter of the second pre-tightening sealing structure is smaller than the caliber of the installation opening; and

[0016] A second connector seat movably penetrates the installation opening, and the second connector seat has an elastic fitting structure, and the second pre-tightening sealing structure is sealingly fitted to the elastic fitting structure, so that the second connector seat can shake with the first connector seat when the second connector seat is inserted and fitted to the first connector seat on the battery pack body.

[0017] In some embodiments, the second pre-tightening sealing structure comprises an elastic body and a buckle portion connected to each other, the elastic body is sealingly abutted to the second connector seat, and the buckle portion is fitted to the clamping groove of the outer circumferential wall of the second connector seat.

[0018] In some embodiments, a sealing ring is sleeved on the end of the second pre-tightening sealing structure away from the second connector seat, the sealing ring extends towards the first connector seat to form a horn blocking portion, and the horn blocking portion is used to abut against the first connector seat.

[0019] A connector fitting kit, comprising the connector socket of any one of the above embodiments and the connector plug of any one of the above embodiments, and the first connector seat is inserted and fitted to the second connector seat.

[0020] A battery pack, comprising a battery pack body and the connector socket of any one of the above embodiments; and the installation component is mounted on the battery pack body.

[0021] Compared with the prior art, the present disclosure has at least the following advantages:

[0022] The aforementioned connector socket, due to the sealing fit between the first pre-tightening sealing structure and the elastic fitting structure, not only reliably confines the first connector seat within the assembly opening through the first pre-tightening sealing structure, but also achieves a sealing effect through the connection between the first pre-tightening sealing structure and the elastic fitting structure, thus ensuring both reliable installation and waterproof and dustproof performance. Simultaneously, the inner diameter of the first pre-tightening sealing structure is smaller than the diameter of the assembly opening, creating a movable gap. When bumps occur, the interlocking first and second connector seats can shake together, reducing loosening. Attached Figure Description

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0033] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0034] like Figure 1 As shown, a connector socket 100 in one embodiment includes a mounting component 110, a first pre-tightening sealing structure 120, and a first connector seat 130. The mounting component 110 is used to mount on the battery pack body. The mounting component 110 has an assembly opening 101. The first pre-tightening sealing structure 120 is disposed at the assembly opening 101 and fixedly connected to the mounting component 110. The inner diameter of the first pre-tightening sealing structure 120 is smaller than the diameter of the assembly opening 101. The first connector seat 130 is movably inserted into the assembly opening 101. The first connector seat 130 has an elastic fit structure. The first pre-tightening sealing structure 120 is sealed and fitted to the elastic fit structure so that when the first connector seat 130 is inserted into the second connector seat 230 fitted on the vehicle body mounting seat 220, it vibrates with the second connector seat 230.

[0035] It can be understood that, since the first pre-tightening sealing structure 120 is sealingly fitted to the elastic fitting structure, not only can the first guide connector 130 be firmly defined in the assembly opening 101 by the first pre-tightening sealing structure 120, but also a sealing effect can be achieved through the connection between the first pre-tightening sealing structure 120 and the elastic fitting structure, so as to take into account the firmness of installation and the waterproof and dustproof performance. At the same time, the inner diameter of the first pre-tightening sealing structure 120 is smaller than the caliber of the assembly opening 101, so that a movable gap is formed, and when jolting occurs, the first guide connector 130 and the second guide connector 230 that are inserted into each other can vibrate together to reduce looseness.

[0036] In combination Figure 1 As shown in some embodiments, the insertion sites on the first guide connector 130 are arranged in at least two rows, and the end face of the first guide connector 130 is circular, so that more insertion sites can be arranged, which is more compact and small compared with the traditional arrangement of insertion sites arranged in a line, and can be used in a narrow space.

[0037] In combination Figure 2 As shown in some embodiments, the first pre-tightening sealing structure 120 has a connected elastic body 121 and a locking portion 122, the elastic body 121 is sealingly abutted to the first guide connector 130, and the locking portion 122 is in clamping cooperation with the outer peripheral wall of the first guide connector 130. It can be understood that, by sealingly abutting the elastic body 121 to the first guide connector 130, the elastic body 121 can provide elastic force to the locking portion 122 to lock the first guide connector 130, so that the first guide connector 130 can be tightly connected to the first pre-tightening sealing structure 120 under the action of the elastic force, and can be driven by the second guide connector 230 when the two-wheeled electric vehicle jolts.

[0038] In combination Figure 2 As shown in some embodiments, the elastic body 121 is arranged around the first guide connector 130, and a contraction clamping cavity 1201 is formed in the elastic body 121; part of the first guide connector 130 is accommodated in the contraction clamping cavity 1201 and abuts against the cavity wall of the contraction clamping cavity 1201. It can be understood that, the elastic body 121 is arranged around the fitting end of the first guide connector 130, so that the first guide connector 130 can be wrapped by the elastic body 121, and the cavity wall of the contraction clamping cavity 1201 abuts against the first guide connector 130, further restraining the first guide connector 130, which can effectively prevent the first guide connector 130 from being pulled out of the assembly opening 101. In some embodiments, the elastic body 121 can be an elastic sleeve structure or an annular elastic clamping jaw structure, and the specific structure is not limited herein, and a person skilled in the art can select as needed.

[0039] In combination Figure 2As shown, in some embodiments, the elastic body 121 comprises at least two elastic clamping pieces 1210 arranged in sequence along the circumference of the first guide socket 130, and a micro-motion gap 1202 is formed between adjacent two elastic clamping pieces 1210. It can be understood that the elastic clamping pieces 1210 are arranged in sequence along the circumference of the first guide socket 130, and the first guide socket 130 is clamped by the elastic clamping pieces 1210 collectively, while the micro-motion gap 1202 between adjacent two elastic clamping pieces 1210 can be synchronously reduced or expanded to adaptively adjust the clamping strength of the first guide socket 130 when the two-wheeled electric vehicle bounces during driving, so that the first guide socket 130 can be kept in a micro-motion state at the assembly opening 101.

[0040] In combination Figure 1 With Figure 2 As shown, in some embodiments, a limiting groove 1301 is formed on the outer circumferential wall of the first guide socket 130, and the lock catch 122 is embedded in the limiting groove 1301. It can be understood that, since the limiting groove 1301 is formed on the outer circumferential wall of the first guide socket 130, the lock catch 122 is embedded in the limiting groove 1301, and the lock catch 122 interferes with the groove wall of the limiting groove 1301, so that the position of the first guide socket 130 can be further locked.

[0041] In combination Figure 1 As shown, in some embodiments, a guide protrusion 111 is arranged on the circumferential wall of the assembly opening 101; a directional guide groove 1302 is further arranged on the outer circumferential wall of the first guide socket 130, and the directional guide groove 1302 is arranged intersecting with the limiting groove 1301; and the guide protrusion 111 is slidingly fitted in the directional guide groove 1302. It can be understood that, by slidingly fitting the guide protrusion 111 in the directional guide groove 1302, the first guide socket 130 can be assembled in the assembly opening 101, and since the directional guide groove 1302 is arranged intersecting with the limiting groove 1301, the groove wall of the directional guide groove 1302 abuts against the guide protrusion 111 to prevent the first guide socket 130 from rotating axially in the assembly opening 101.

[0042] As Figure 3 With Figure 4As shown, the disclosure also provides a guide connector 200 comprising a vehicle body fixing seat 220, a second pre-tightening sealing structure 210 and a second guide connector seat 230; the vehicle body fixing seat 220 is used to be installed on a two-wheeled electric vehicle; the vehicle body fixing seat 220 is provided with an installation opening 201; the second pre-tightening sealing structure 210 is arranged at the installation opening 201 and fixedly connected to the vehicle body fixing seat 220; the inner diameter of the second pre-tightening sealing structure 210 is smaller than the caliber of the installation opening 201; the second guide connector seat 230 is movably arranged in the installation opening 201, and the second guide connector seat 230 has an elastic fitting structure, and the second pre-tightening sealing structure 210 is sealingly fitted in the elastic fitting structure, so that the second guide connector seat 230 can shake with the first guide connector seat 130 when the second guide connector seat 230 is inserted and matched with the first guide connector seat 130 on the battery pack body.

[0043] It can be understood that, since the second pre-tightening sealing structure 210 is sealingly fitted in the elastic fitting structure, not only can the second guide connector seat 230 be firmly limited in the installation opening 201 through the second pre-tightening sealing structure 210, but also the connection between the second pre-tightening sealing structure 210 and the elastic fitting structure can play a sealing effect, so as to take into account the firmness of installation and waterproof and dustproof performance. At the same time, the inner diameter of the second pre-tightening sealing structure 210 is smaller than the caliber of the installation opening 201, so that an active gap can be formed, and when jolting occurs, the second guide connector seat 230 and the first guide connector seat 130 that are inserted with each other can shake together to reduce looseness.

[0044] In combination Figure 4 As shown, in some embodiments, the second pre-tightening sealing structure 210 comprises an elastic body 211 and a buckle part 212 connected with each other, the elastic body 211 is sealingly abutted to the second guide connector seat 230, and the buckle part 212 is matched with the clamping groove of the outer peripheral wall of the second guide connector seat 230. It can be understood that, by sealingly abutting the elastic body 211 to the second guide connector seat 230, the elastic force can be provided to the buckle part 212 to lock the second guide connector seat 230 through the buckle part 212, so that the second guide connector seat 230 can be tightly connected with the second pre-tightening sealing structure 210 under the action of the elastic force, and can be driven by the first guide connector seat 130 when the two-wheeled electric vehicle jolts.

[0045] In combination Figure 4 With Figure 5As shown, in some embodiments, the second connector 230 is sleeved with a sealing ring 310 at one end away from the second pre-tightening sealing structure 210, the sealing ring 310 extends to the first connector 130 to form a horn blocking part 311, and the horn blocking part 311 is used to press against the first connector 130. It can be understood that by pressing the horn blocking part 311 against the first connector 130, not only can the buffering force be provided when the second connector 230 and the first connector 130 are shaken, but also the waterproof performance of the position where the second connector 230 and the first connector 130 are matched can be improved to achieve IPX7 waterproof level.

[0046] As shown, Figure 5 The present disclosure also provides a connector matching kit 10, which includes the connector socket 100 of any of the above embodiments and the connector plug 200 of any of the above embodiments, and the first connector 130 is plugged into the second connector 230. It can be understood that by sealingly matching the first pre-tightening sealing structure 120 with the elastic matching structure, the first pre-tightening sealing structure 120 can firmly limit the first connector 130 in the assembly opening 101, and the connection between the first pre-tightening sealing structure 120 and the elastic matching structure can have a sealing effect, so as to take into account the firmness of installation and waterproof and dustproof performance. In addition, by sealingly matching the second pre-tightening sealing structure 210 with the elastic matching structure, the second pre-tightening sealing structure 210 can firmly limit the second connector 230 in the mounting opening 201, and the connection between the second pre-tightening sealing structure 210 and the elastic matching structure can have a sealing effect, so as to take into account the firmness of installation and waterproof and dustproof performance.

[0047] The present disclosure also provides a battery pack, which includes a battery pack body and the connector socket 100 of any of the above embodiments; and the mounting component 110 is mounted on the battery pack body. It can be understood that by applying the connector socket 100 of the present disclosure to the battery pack, the mounting component 110 is mounted on the battery pack body, and after the battery pack is mounted on the vehicle body fixing seat 220 of the two-wheeled electric vehicle, the first pre-tightening sealing structure 120 is sealingly matched with the elastic matching structure, so that the first pre-tightening sealing structure 120 can firmly limit the first connector 130 in the assembly opening 101, and the connection between the first pre-tightening sealing structure 120 and the elastic matching structure can have a sealing effect, so as to take into account the firmness of installation and waterproof and dustproof performance.

[0048] Compared with the prior art, the present disclosure has at least the following advantages:

[0049] The first pre-tightening sealing structure 120 is sealed to the elastic fitting structure, so that the first guide socket 130 is firmly limited in the assembly opening 101 by the first pre-tightening sealing structure 120, and the connection between the first pre-tightening sealing structure 120 and the elastic fitting structure can achieve a sealing effect, so as to balance the firmness of installation and the waterproof and dustproof performance.
