[0026] With reference to the Fig. 1 to 23, the present invention provides a battery mounting structure for mounting the battery body 1 in the battery compartment 2, the battery body 1 having a first surface 10 and a second surface 11 arranged opposite one another, at least a portion of the second surface 11 being in contact with a bottom surface of the battery compartment 2, the battery mounting structure comprising a connecting member 3 arranged laterally on the battery body 1, the connecting member 3 being provided with a first abutment surface 30, wherein in a direction from the first surface 10 to the second surface 11, the first abutment surface 30 is inclined in a direction gradually away from the battery body 1; a fastening member 4 buckled to the connecting member 3, the fastening member 4 being provided with a second abutment surface 40, the second abutment surface 40 being an inclined surface;and a fastening layer 5 covering the connecting element 3 and the battery body 1, wherein the fastening layer 5 is adhesively bonded to the first contact surface 30 of the connecting element 3 and the battery body 1; wherein at least a portion of the second contact surface 40 bears against the fastening layer 5; an adhesive layer 6 provided between the connecting element 3 and the battery body 1, wherein the adhesive layer 6 is adhesively bonded to the connecting element 3 and the battery body 1; wherein a positioning portion 20 is provided in the battery compartment 2, wherein the fastening element 4 is detachably connected to the positioning portion 20.

In this way, the connecting element 3 is bonded to the side of the battery body 1 by the adhesive layer 6, and the connecting element 3 is stably connected to the battery body 1 by the fastening layer 5, wherein the second abutment surface 40 cooperates with the first abutment surface 30 via the fastening layer 5. Since the first abutment surface 30 and the second abutment surface 40 are both inclined surfaces, the fastening element 4 can exert a downward force on the connecting element 3 when the fastening element 4 is buckled to the connecting element 3, thereby restricting displacement of the battery body 1 in the vertical direction;The battery body 1 can be fixed in the battery compartment 2 through the cooperation between the connecting member 3 and the fastening member 4, and the fastening member 4 and the positioning portion 20 can be detachably connected to realize the disassembly and assembly of the battery body 1.

[0028] In particular, the battery mounting structure further includes a restricting portion 31 provided on the connecting member 3, at least a portion of the restricting portion 31 protruding relative to the first abutment surface 30 in a direction away from the battery body 1; and an escape part 41 arranged on the fastening member 4, at least a portion of the escape part 41 abutting against the upper surface 311 of the restricting portion 31. To enhance the restricting effect of the fastening member 4, a restricting portion 31 is provided on the connecting member 3, and the escape portion 41 abuts against the upper surface 311 of the restricting portion 31, so that the fastening member 4 exerts a force on the restricting portion 31 to fix the battery body 1.

[0029] In a specific implementation, the limiting portion 31 comprises a limiting block 310; wherein the escape part 41 has a first escape end surface 411 and a second escape end surface 412 which are connected to each other, wherein a first angle is formed between the first escape end surface 411 and the second escape end surface 412, wherein an escape gap 413 is formed between the first escape end surface 411 and the second escape end surface 412; wherein the limiting block 310 is arranged in the escape gap 413, wherein at least a portion of the first escape end surface 411 is in contact with the upper surface 311. By providing the escape gap 413, the limiting block 310 is prevented from impairing the degree of contact of the second abutment surface 40 with the first abutment surface 30.At the same time, the first escape end surface 411 is used to exert a force on the limiting block 310 to limit the position of the battery body 1.

[0030] Preferably, the width of the limiting block 310 is H, where 1 mm ≤ H ≤ 3 mm; and / or the thickness of the limiting block 310 is L, where 1 mm ≤ L ≤ 3 mm. As shown in the Fig. 5 and Fig. 6, the longitudinal section of the limiting block 310 is rectangular.

[0032] In the present invention, the connecting element 3 has a counter end surface 32 which abuts against the bottom surface of the battery compartment 2, wherein the counter end surface 32 is connected to the first abutment surface 30; wherein the angle between the first abutment surface 30 and the counter end surface 32 is α, where 60°≤α≤89°; and / or wherein the width of the counter end surface 32 is W, where 1 mm ≤ W ≤ 3 mm. Preferably, the longitudinal section of the connecting element 3, as shown in the Fig. 7 and Fig. 8, a right-angled triangle or a right-angled trapezoid.

[0033] As in the Fig. 15 and Fig. 16, the fastening element 4 has an abutment body 42 which is buckled to the connecting element 3, wherein the second abutment surface 40 is provided on the abutment body 42; and a fastening body 43 which is arranged at the end of the abutment body 42, wherein a second angle is formed between the extending direction of the fastening body 43 and the extending direction of the abutment body 42, wherein the fastening body 43 and the positioning section 20 are arranged opposite one another; wherein the positioning section 20 has a first connecting hole, wherein the fastening body 43 is provided with a second connecting hole 430 opposite the first connecting hole and is inserted into the first connecting hole and the second connecting hole one after the other by the fastening element, and wherein the fastening element is screwed to the first connecting hole.Preferably, the positioning section 20 is a positioning post in which the first connection hole is a threaded hole and the fastening element is a bolt, wherein the fastening element 4 can be disassembled and assembled by screwing in the bolts. In a further development, it is provided that the first deflection end surface 411 is provided on the fastening body 43, wherein the second deflection end surface 412 is provided on the contact body 42. The longitudinal section of the contact body 42 is a right-angled trapezoid, and the slope of its hypotenuse corresponds to the slope of the hypotenuse of the longitudinal section of the connecting element 3, wherein the length of the second contact surface 40 is equal to the length of the first contact surface 30.

[0034] In a first embodiment provided in the present invention, as shown in the Fig. 1 to 11, the connecting element 3 is glued to the side of the battery body 1. As shown in Fig. 9, the thickness of the adhesive layer 6 is C, where 0.1 mm ≤ C ≤ 0.3 mm, the adhesive layer 6 does not extend beyond the side sealing edge of the battery body 1 and does not overlap the rounded corner of the battery body 1, the length of the adhesive layer 6 is equal to the length of the side of the battery body 1, and the width of the adhesive layer 6 is equal to the width of the side of the battery body 1, the bottom surface of the adhesive layer 6, the counter end surface 32 of the connecting member 3, and the bottom surface of the battery body 1 are in the same plane; the fixing layer 5 is an adhesive paper, and the side of the adhesive paper that abuts the connecting member 3 and the battery body 1 is covered with strong adhesive, the fixing layer 5 is adhered to the connecting member 3 and the battery body 1, and the connecting member 3 is firmly connected to the battery body 1;Preferably, the fastening layer 5 is in contact with the first contact surface 30 during wrapping, and the limiting portion 31 is used to limit the movement of the fastening layer 5 in the length direction of the battery body 1. As shown in FIG. Fig. 11, the fixing layer 5 is a rectangular adhesive paper, the width corresponds to the length of the first contact surface 30, and the length is 1.5 to 2 times the width of the battery body 1. It should be noted that the length direction of the connecting element 3 coincides with the length direction of the battery body 1.

[0035] The fastening element 4 presses the fastening layer 5 against the connecting element 3. The first abutment surface 30 and the second abutment surface 40 are each adapted by an inclined surface to compensate for the gap between the width direction of the battery body 1 and the battery compartment 2 during assembly. During assembly of the fastening element, by sliding the inclined second abutment surface 40 downward, an obliquely downward fastening force is exerted on the battery body 1, thereby limiting the left-right and up-down movements of the battery body 1. For example, if the width of the battery body 1 is too narrow, the fastening element 4 is positioned downward during assembly, and the gap between its side and the inside of the battery compartment 2 is reduced.For example, if the width of the battery body 1 is too large, the fastener 4 is positioned upward during assembly, and the gap between its side and the inside of the battery compartment 2 becomes larger.

[0036] In a second embodiment provided in the present invention, as shown in the Fig. 17 to 20, the difference between this embodiment and the first embodiment is that, in this embodiment, the connecting member 3 is fixed to the battery body 1 by injection molding without providing an adhesive layer 6 and a fixing layer 5, and the injection molding process is for injection molding the connecting member on both sides of the battery body 1, the rounded corner of the battery body 1 and a gap portion within a side sealing edge are each filled with adhesive closer to the side of the battery body 1, and the connecting member 3 is more firmly bonded to the battery body 1.

[0037] In a third embodiment provided in the present invention, as shown in the Fig. 21 and Fig. 22, the battery body 1 is a steel-shell battery, and the battery body 1 is provided with a flange edge 12; wherein the connecting member 3 has a third surface 33 and a fourth surface 34 arranged opposite one another, at least a portion of the fourth surface 34 being in contact with a bottom surface of the battery compartment 2; wherein the width of the third surface 33 is greater than or equal to the width of the flange edge 12. This arrangement can prevent the fastening member 4 from contacting the flange edge 12 during assembly of the fastening member 4, which would lead to the problem that the fastening member 4 cannot be assembled.Compared with soft pack batteries, the side surfaces of steel shell batteries are smoother and the adhesive layer 6 is bonded more stably, whereby the size of the adhesive layer 6 can be designed relatively larger and the fixing layer 5 can be omitted according to the actual conditions.

[0038] In a fourth embodiment provided in the present invention, as shown in Fig. 23, this embodiment differs from the third embodiment in that the connecting element 3 can be directly molded onto both sides of the steel shell battery, so that the connecting element 3 is stably connected to the battery body 1.

[0039] This invention also provides a mobile device comprising a battery mounting structure and a device body, the device body being provided with a battery compartment 2, the battery mounting structure being detachably mounted in the battery compartment 2, the battery mounting structure being the battery mounting structure according to the above embodiments.

[0040] In the present invention, the disassembly and assembly process of the battery body 1 includes an assembly process and a disassembly process. Assembly process:
