I DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
2 With reference to Figs. 1 and 2, a battery installation mechanism 3 assembled to a rollator has a base 10, a limiting assembly 20, and a battery 30.
4 Wheels of the rollator are rotatably assembled to the base 10. The limiting assembly 20 and the battery 30 are assembled to the base 10. The battery 30 is 6 limited between the base 10 and the limiting assembly 20.
7 With reference to Figs. 1 to 3, the base 10 has a supporting unit 11, a 8 frame 12, and a connecting mount 13. The supporting unit 11 has a supporting 9 board 111, two engaging lugs 112, and two engaging holes 113. The two engaging lugs 112 are erectly connected to the supporting board 111. The two 11 engaging holes 113 are respectively defined through the two engaging lugs 112.
12 The frame 12 surrounds the supporting unit 11. The connecting mount 13 is 13 connected to the supporting board 111 and has a connecting terminal 131.
14 With reference to Figs. 3 to 5, the limiting assembly 20 has an assembling mount 21, a limiting component 22, a connecting member 23, an 16 operating handle 24, and an elastic unit 25. The assembling mount 21 is fastened 17 to the supporting board 111. The assembling mount 21 has a receiving slot 211 18 and a containing groove 212. The receiving slot 211 has an opening and a bottom.
19 The receiving slot 211 is defined in a face of die assembling mount 21, wherein the face faces to the two engaging lugs 112. The containing groove 212 is 21 defined in another face of the assembling mount 21, wherein the face faces to a 22 direction opposite to the two engaging lugs 112. The limiting component 22 is 23 received in the receiving slot 211. The limiting component 22 has an abutted face 24 221 and an embedding recess 222. The abutted face 221 is exposed outside the I receiving slot 211. The embedding recess 222 is defined in a portion of the 2 limiting component 22, wherein the portion is disposed below the abutted face 3 221. A nut 223 is embedded in the embedding recess 222. In the present 4 invention, the connecting member 23 is a bolt. The connecting member 23 extends through the assembling mount 21 and has two opposite ends. More 6 specifically, the connecting member 23 is screwed with the nut 223, and one of 7 the two opposite ends of the connecting member 23 is connected to the limiting 8 component 22. The connecting member 23 extends through the limiting 9 component 22, enters the receiving slot 211 of the assembling mount 21, extends through the bottom of the receiving slot 211, and enters the containing groove 11 212. The operating handle 24 is annular and is screwed with and connected to the 12 other one of the two opposite ends of the connecting member 23. The elastic unit 13 25 has two opposite ends respectively abutting against the limiting component 14 22 and the bottom of the receiving slot 211 of the assembling mount 21. The elastic unit 25 is compressible and restorable between the limiting component 22 16 and the assembling mount 21. More specifically, the elastic unit 25 is a 17 compression spring 25 mounted around the connecting member 23. As long as 18 the elastic unit 25 is capable of being compressed and restoring between the 19 limiting component 22 and the assembling mount 21, the elastic unit 25 can be any components with elasticity.
21 With reference to Figs. 1, 2, and 6, in the present invention, the battery 22 30 is a lithium battery. The battery 30 is disposed between the two engaging lugs 23 112 and the assembling mount 21 and has a cartridge 31, two engaging 24 protrusions 32, a limiting protrusion 33, a battery terminal 34, and a protecting I lid 35. The cartridge 31 has a bottom, a first end, and a second end opposite the 2 first end of the cartridge 31. The two engaging protrusions 32 protrude from the 3 first end of the cartridge 31. The two engaging protrusions 32 are respectively 4 inserted in the two engaging holes 113. The limiting protrusion 33 protrudes from the second end of the cartridge 31 and has an abutting portion 331. The 6 abutting portion 331 inclines toward the bottom of the cartridge 31 and 7 corresponds to the abutted face 221 of the limiting component 22 in shape. The 8 abutting portion 331 is capable of abutting against the abutted face 221. When 9 the limiting protrusion 33 is limited by the limiting component 22, the battery 30 is restricted between the base 10 and the limiting assembly 20. The battery 11 terminal 34 is disposed at the bottom of the cartridge 31. The battery terminal 33 12 is capable of being electrically connected to the connecting terminal 13! of the 13 connecting mount 13. The protecting lid 35 is pivotally connected to the 14 cartridge 31 and is capable of covering the battery terminal 34.
With reference to Figs. 6 and 7, when the battery 30 is installed to the 16 base 10, the protecting lid 35 is opened at first to expose the battery terminal 34.
17 Then the two engaging protrusions 32 of the battery 30 are respectively inserted 18 into the two engaging holes 113 of the supporting unit 11. With reference to Figs. 19 5 to 7, when the second end of the cartridge 31 is swept toward the base 10, the abutting portion 331 of the limiting protrusion 33 abuts against the abutted face 21 221 of the limiting component 22. The limiting protrusion 33 pushes the limiting 22 component 22 into the receiving slot 211 of the assembling mount 21. The 23 limiting component 22 compresses the elastic unit 25 accordingly. With 24 reference to Figs. 6 to 8, when the battery teiminal 34 is electrically connected to I the connecting terminal 131 of the connecting mount 13, the abutting portion 2 331 no longer abuts against the abutted face 221. The elastic unit 25 restores and 3 pushes the limiting component 22 out from the receiving slot 211 of the 4 assembling mount 21. The limiting component 22 blocks above the limiting protrusion 33. Therefore, the battery 30 is limited between the base 10 and the 6 limiting assembly 20.
7 With reference to Figs. 8 and 9, to remove the battery 30 from the base 8 10, the operating handle 24 of the limiting assembly 20 is pulled firstly The 9 operating handle 24 drags the limiting component 22 into the receiving slot 211 and does not block above the limiting protrusion 33 anymore. The second end of 11 the cartridge 31 can be swept away from the base 10. The two engaging 12 protrusions 32 of the battery 30 are retrieved from the two engaging holes 113.
13 The battery 30 can be removed from the base 10 consequently. The battery 14 installation mechanism in accordance with the present invention is simple in structure, is easy to operate, and is convenient for battery replacement, thereby 16 having advantages in assembly and maintenance.
17 Even though numerous characteristics and advantages of the present 18 invention have been set forth in the foregoing description, together with details 19 of the structure and features of the invention, the disclosure is illustrative only.
Changes may be made in the details, especially in matters of shape, size, and 21 arrangement of parts within the principles of the invention to the full extent 22 indicated by the broad general meaning of the terms in which the appended 23 claims are expressed.
