DETAILED DESCRIPTION

[0036] The utility model discloses a battery installation assembly, which realizes the detachable fixed connection of the battery. In addition, the utility model also discloses a travel tool vehicle with the battery installation assembly.

[0037] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0039] like Figure 1 As shown, the present application discloses a battery mounting assembly, including a mounting base assembly 100 and a battery assembly 200 , wherein the battery assembly 200 can be detachably fixed on the mounting base assembly 100 .

[0040] The battery assembly 200 includes a battery body 201, a handle 202, and a first connector. The handle 202 is hinged to the battery body 201. In some embodiments, the handle 202 includes but is not limited to two ends of the handle 202 being hinged to two sides of the battery body 201. The first connector is fixedly connected to the handle 202. In some embodiments, the first connector is fixed to two ends of the handle 202.

[0041] Figure 1The handle 202 is a U-shaped member, and both ends are hinged to the two sides of the battery body 201 respectively, and the first connecting member is fixed to the end of the handle 202.

[0042] The mounting base assembly 100 includes: a mounting base 101 and a second connecting member.

[0043] The mounting base 101 has a mounting groove (not shown in the figure), and the battery body 201 can be fixed in the mounting groove. A second connecting member is arranged on the mounting base 101 and at the edge of the mounting groove.

[0044] It should be noted that the first connector and the second connector in this article can be detachably connected to achieve a fixed connection between the battery body 201 and the mounting base 101.

[0045] Since the first connecting member is fixedly connected to the handle 202, when the handle 202 is rotated, the first connecting member rotates with the handle 202, thereby changing the relative position of the first connecting member and the second connecting member. When the handle 202 is rotated to the first position, the first connecting member is engaged with the second connecting member; when the handle 202 is rotated to the second position, the first connecting member is separated from the second connecting member, thereby realizing the disassembly of the battery body 201 and the mounting base 101.

[0046] In the battery mounting assembly disclosed in the present application, the battery body 201 and the mounting base 101 are fixedly connected by abutting against each other through the first connecting member and the second connecting member, and are detachable by separating the first connecting member and the second connecting member, thereby completing the detachable fixed connection of the battery body 201 on the mounting base 101; in addition, since the first connecting member is fixedly connected to the handle 202, the relative positions of the first connecting member and the second connecting member can be changed during the rotation of the handle 202, thereby simplifying the operation, improving the rapid disassembly and assembly of the battery assembly 200 and the mounting base 101, and achieving a user experience that is convenient and easy to disassemble.

[0047] In some embodiments, the first connector and the second connector are snap-connected, hooked or plugged in. The connection method of the first connector and the second connector can be set according to different needs, as long as the first connector and the second connector can be connected in the first position during the relative rotation of the first connector and the second connector, and the first connector and the second connector are separated in the second position.

[0048] In an exemplary embodiment, the first connector is a first clamping member 203, the second connector is a second clamping member 102, and the first clamping member 203 and the second clamping member 102 can be clamped together. The following content is described in detail in the manner in which the first connector and the second connector are clamped together:

[0049] Since the first clamping member 203 is fixedly connected to the handle 202, the first clamping member 203 rotates with the handle 202 during the rotation of the handle 202, thereby changing the relative position of the first clamping member 203 and the second clamping member 102. When the handle 202 is rotated to the first position, the first clamping member 203 is engaged with the second clamping member 102; when the handle 202 is rotated to the second position, the first clamping member 203 is separated from the second clamping member 102, thereby realizing the disassembly of the battery body 201 and the mounting base 101.

[0050] See also Fig. 9 As shown, in some embodiments, the handle 202 is in a first position, the handle 202 is received in a snap-fit ​​groove of the battery body 201 , and the handle 202 is parallel to the upper surface of the battery body 201 ; the handle 202 is in a second position, and the handle 202 is perpendicular to the upper surface of the battery body 201 .

[0051] In some embodiments, the rotation angle of the handle 202 is 90°. When the rotation angle of the handle 202 is 0°, the first clamping component 203 and the second clamping component 102 are clamped, and the battery body 201 is fixed on the mounting base 101; when the rotation angle of the handle 202 is 90°, the first clamping component 203 and the second clamping component 102 are separated, and the battery body 201 can be separated from the mounting base 101.

[0052] Combination Figures 2 to 4 As shown, the first clamping member 203 includes: a connecting rod 2031 , an abutting member 2032 and a connecting member 2033 .

[0053] One end of the connecting rod 2031 is fixedly connected to the handle 202, including but not limited to being fixed to the handle 202 through a connecting member 2033. In some embodiments, the connecting member 2033 is a connecting column, which is fixed to the battery body 201, and the handle 202 and the connecting rod 2031 are both rotatably connected to the connecting member 2033, and the handle 202 is fixedly connected to the connecting rod 2031.

[0054] In the present application, the handle 202 and the connecting rod 2031 are arranged coaxially, which can ensure that the rotation center of the handle 202 is concentric with the connecting rod 2031.

[0055] The abutment member 2032 is fixed to the other end of the connecting rod 2031 and faces the side away from the battery body 201. When the connecting rod 2031 rotates with the handle 202, the stroke of the abutment member 2032 is an arc, and the second clamping member 102 is within the stroke range of the abutment member 2032.

[0056] In some embodiments, the connecting rod 2031 is arranged perpendicular to the plane where the handle 202 is located. By arranging the connecting rod 2031 perpendicularly to the handle 202, when the handle 202 is in the first state, the first clamping member 203 and the second clamping member 102 are in a vertically abutting state, ensuring that the gravity direction coincides with the battery body 201.

[0057] See also Figure 4 As shown, in order to prevent the handle 202 from being separated from the battery body 201 in the first state, the battery body 201 has a handle engaging groove, the engaging groove has an engaging side surface, and an elastic plunger 2011 is arranged on the engaging side surface; the handle 202 has a handle side surface, and the handle side surface will be in contact with the engaging side surface during the rotation of the handle. The handle side surface has a limiting hole 2022 facing the elastic plunger 2011, and the elastic plunger 2011 is engaged with the limiting hole 2022.

[0058] In some embodiments, the expansion and contraction direction of the elastic plunger 2011 is parallel to the upper surface of the battery body 201 , that is, the elastic plunger 2011 is installed on the side wall of the engaging groove that is perpendicular to the upper surface of the battery body 201 .

[0059] Exemplarily, the battery body 201 has a recessed portion near the upper surface of the circumferential edge, which extends along the circumference of the battery body 201 and forms a snap-fit ​​groove. The shape of the snap-fit ​​groove is adapted to the shape of the handle 202, including but not limited to a U-shaped groove, and the snap-fit ​​groove along the circumference of the battery body 201 includes a first portion, a second portion, and a third portion in sequence, wherein the first portion and the third portion are arranged oppositely, and the two ends of the handle 202 are respectively hinged to the first portion and the third portion, and the second portion forms a snap-fit ​​side surface.

[0060] At least one elastic plunger 2011 may be arranged along the extension direction of the second portion, including but not limited to two or three. The elastic plunger 2011 may use an existing known elastic plunger structure, and the elastic plunger 2011 includes but is not limited to being fixed in the mounting hole of the engaging side by a positioning pin. When the handle 202 is in the first state, the lower side has a gripping position, which is convenient for the operator to grasp the handle 202. The shape and size of the gripping position can be set according to different needs and are all within the protection range.

[0061] The operator's finger can buckle the handle 202 through the buckle position, so that the elastic plunger 2011 is separated from the limiting hole 2022. When the handle 202 is reset and buckled, the head of the elastic plunger 2011 supports the limiting hole 2022 by the spring force.

[0062] The elastic plunger 2011 and the limiting hole 2022 are used to limit the handle 202 so that the handle 202 cannot be separated from the engaging groove without applying external force when the handle 202 is in the first state.

[0063] It should be noted that the elastic plunger 2011 can be replaced by a spring, a buckle, or directly fixed by hand-tightening a nut.

[0064] like Figure 2 and Figure 3 As shown, the battery assembly 200 further includes: a charging port 204 , a side wall guide groove 205 , a battery discharge port 206 and a back plate guide groove 207 .

[0065] The side wall guide groove 205 and the back plate guide groove 207 are grooves that gradually expand from the upper surface to the lower surface of the battery body 201. The number and location of the side wall guide groove 205 and the back plate guide groove 207 can be set according to different needs.

[0066] The charging port 204 in the present application is arranged on the side of the battery body 201, and the battery discharge port 206 is a waterproof port and is arranged at the bottom of the battery body 201. The battery discharge port 206 is waterproof in a manner including but not limited to sleeve a waterproof cover on the outside of the plug of the battery discharge port 206 or apply a waterproof coating on the outside of the plug. That is, the charging port 204 and the battery discharge port 206 are located on different surfaces of the battery body 201, so that the user does not need to turn over the battery body 201 for charging after taking out the battery body 201, which reduces the labor intensity of the operation.

[0067] Combination Figure 5 As shown, in some embodiments, the second clamping member 102 is a protrusion fixed to the mounting base 101 and located at the outer edge of the mounting groove. Specifically, the end of the protrusion away from the mounting base 101 has a concave abutting arc surface, and the abutting arc surface can fit with the abutting member 2032.

[0068] In some embodiments, the abutting member 2032 is a cylinder, and the abutting arc surface is a semicircular arc surface.

[0069] The mounting groove disclosed in some embodiments includes a back plate, a bottom plate and side walls, wherein the back plate and the bottom plate are arranged to intersect and respectively cooperate with the bottom and side of the battery body 201. The structure formed by the back plate and the bottom plate includes but is not limited to forming an L-shaped groove, and the two opposite side walls of the mounting groove are inclined plates inclined from the back plate of the mounting groove to the bottom plate of the mounting groove.

[0070] In some embodiments, the outer edges of the two side walls of the installation slot are provided with lateral guide posts 104, and the back plate of the installation slot is provided with back plate guide posts 103. The number and location of the lateral guide posts 104 and back plate guide posts 103 can be set according to different needs and are not specifically limited here.

[0071] The lateral guide posts 104 and the back plate guide posts 103 are guide posts that gradually expand from the upper notch of the mounting slot toward the bottom plate.

[0072] The lateral guide column 104 is used to cooperate with the side wall guide groove 205, and the back plate guide column 103 is used to cooperate with the back plate guide groove 207 to achieve the guidance and positioning of the battery body 201 during the installation process in the installation groove. Of course, the positions of the guide column and the guide groove can be interchanged on the battery body 201 and the installation groove.

[0073] The bottom plate of the mounting groove is provided with a groove bottom discharge port 107. A baffle 106 is provided on the side of the bottom plate of the mounting groove away from the back plate, and the baffle 106 and the back plate limit the movement of the battery body 201 in the direction of the baffle 106 and the back plate, so as to limit and fix the battery body 201.

[0074] The baffle 106 can shield the charging port 204 of the battery body 201 installed on the mounting base 101 to prevent the installed battery body 201 from being charged, thereby ensuring the safety of the entire vehicle. After the battery body 201 is installed on the mounting base 101, it can be charged through the charging port of the entire vehicle.

[0075] Combination Figures 5 to 8 As shown, the bottom plate of the installation slot is provided with a retractable pressing block 105, and the retracting direction of the pressing block 105 is perpendicular to the bottom plate of the installation slot.

[0076] When the battery body 201 is installed in the installation slot, the battery body 201 presses the pressing block 105 to offset the assembly gap between the battery body 201 and the installation slot; and the elastic expansion and contraction of the pressing block 105 can buffer and stop vibration of the battery body 201.

[0077] In some embodiments, the force direction of the pressure block 105 on the battery body 201 is on a straight line with the clamping limit direction of the first clamping member 203 and the second clamping member 102, and the center of gravity of the battery body 201 is also on this straight line, so that the battery body 201 is evenly stressed and the portable battery body 201 will not be skewed.

[0078] See also Figure 8 As shown, the pressing block 105 includes a pressing cap 1051 , a bolt 1052 and a spring 1053 .

[0079] The bolt 1052 is installed on the mounting hole of the mounting base 101 . The mounting hole is a through hole perpendicular to the bottom plate of the mounting groove. The bolt 1052 can move along the axial direction of the mounting hole.

[0080] In some embodiments, the mounting hole is a stepped hole, and the first end of the bolt 1052 can be positioned against the side of the mounting hole step away from the mounting slot, and the pressure cap 1051 is fixed to the second end of the bolt 1052, and the pressure cap 1051 is exposed on the bottom plate of the mounting slot.

[0081] One end of the spring 1053 abuts against the pressing cap 1051, and the other end abuts against the side of the mounting hole step close to the mounting slot. Under the action of the spring 1053, the bolt 1052 abuts against the mounting hole, and the pressing cap 1051 is exposed on the bottom plate of the mounting slot; when the pressing cap 1051 is squeezed by the battery body 201, the pressing cap 1051 pushes the bolt 1052 to move away from the mounting slot, and the spring 1053 is compressed.

[0082] When the battery body 201 is separated from the mounting groove, the spring 1053 is reset and the pressing cap 1051 moves in a direction to be exposed outside the mounting groove.

[0083] It should be noted that the size of the bottom plate of the pressure cap 1051 exposed from the installation slot can be set according to different needs and is within the protection range.

[0084] The number of the pressing blocks 105 and their positions on the bottom plate can be set according to different needs. Preferably, a plurality of pressing blocks 105 can be symmetrically arranged on both sides of the bottom plate to prevent the battery body 201 from tilting.

[0085] In addition, the present application also discloses a mobility scooter, including a main body and a battery installation assembly, wherein the battery installation assembly is the battery installation assembly disclosed in the above embodiment.
