Description

Technical Field

[0001] The present application relates to a structure, and in particular to a support structure. Background Art

[0002] The internal space of today's devices may not be properly utilized, leaving extra space (i.e., space without components). This extra space will reduce the structural strength of the device, making it easy for the device to deform due to impact when it falls. Today, the way to fill this extra space to improve the structural strength is to fill it with filling materials such as foam. The specifications of general filling materials are limited. When filling a larger space, multiple layers need to be stacked and the volume must be large enough to absorb the impact of falling, which is inconvenient to use.

[0003] For example, a bicycle battery box may contain multiple batteries, and the size of the internal space of the battery box is designed according to different types of batteries. Depending on the use requirements, the number of batteries actually installed in the battery box may be less than the maximum capacity of the battery box, and the excess space in the battery box (i.e., the space without batteries) will affect the overall structural strength of the battery box. When using foam to fill the excess space, a large number of foam layers need to be stacked, which increases the difficulty of setting. In addition, when setting the foam in the battery box corresponding to different types of batteries, the foam needs to be redesigned corresponding to different spaces, which is inconvenient to use.

[0085] Figure 1 An exploded view of a support structure according to an embodiment of the present application is shown. Figure 2 Shows Figure 1 Schematic diagram of the support structure in a first state. Figure 3 Shows Figure 2 Cross-section of the supporting structure. Figure 4 Shows Figure 2 Another cross-section of the support structure. See also Figures 1 to 4, the support structure 100 includes a first bracket 110, a second bracket 120 and at least one spring piece 130. The second bracket 120 is detachably connected to the first bracket 110 along the first axis L1. The first bracket 110 includes a first alignment hole group 111a, a first alignment hole group 111b, and a first alignment hole group 111c, and the second bracket 120 includes a second alignment hole group 121a, a second alignment hole group 121b, and a second alignment hole group 121c. In this embodiment, the number of the first alignment hole group 111a, the first alignment hole group 111b, and the first alignment hole group 111c is three, and the number of the second alignment hole group 121a, the second alignment hole group 121b, and the second alignment hole group 121c is three, but is not limited thereto.

[0086] like Figure 3 As shown, each of the first alignment hole groups 111a, 111b, and 111c includes two first openings P1 disposed correspondingly to each other along the second axis L2, and each of the second alignment hole groups 121a, 121b, and 121c includes two second openings P2 disposed correspondingly to each other along the second axis L2. The first axis L1 is perpendicular to the second axis L2. The second bracket 120 can slide relative to the first bracket 110 along the first axis L1 to change the length of the support structure 100 along the first axis L1.

[0087] When the second bracket 120 is connected to the first bracket 110 and at least one of the three first alignment hole groups 111a, 111b and 111c is aligned with at least one of the three second alignment hole groups 121a, 121b and 121c, the first alignment hole groups and the second alignment hole groups aligned with each other form at least one insertion space S1. Part of the spring sheet 130 can be detachably inserted into the insertion space S1 formed by the first bracket 110 and the second bracket 120 along the second axis L2 to connect to the first bracket 110 and the second bracket 120, thereby fixing the length A1 ( Figure 4 ).

[0088] The support structure 100 can be disposed in a device (not shown) to fill the extra space inside the electronic device to enhance the overall structural strength of the device. The support structure 100 of this embodiment can be switched between three states, so that the support structure 100 has three different lengths, but is not limited thereto. The support structure 100 can be adapted to different situations by switching between different lengths to enhance the convenience of use of the support structure 100.

[0089] like Figure 1 and Figure 3As shown, the first bracket 110 includes a first head 112 and a first neck 113 connected to each other, and the second bracket 120 includes a second head 122 and a second neck 123 connected to each other. The shapes of the first head 112, the first neck 113, the second head 122 and the second neck 123 are, for example, cylindrical. The first alignment hole group 111a, the first alignment hole group 111b, and the first alignment hole group 111c (first opening P1) are located in the first neck 113, and the second alignment hole group 121a, the second alignment hole group 121b, and the second alignment hole group 121c (second opening P2) are located in the second neck 123.

[0090] The width R1 of the first head portion 112 along the second axis L2 (i.e., the diameter of the first head portion 112) is greater than the width R2 of the first neck portion 113 along the second axis L2 (i.e., the diameter of the first neck portion 113). The width R3 of the second head portion 122 along the second axis L2 (i.e., the diameter of the second head portion 122) is greater than the width R4 of the second neck portion 123 along the second axis L2 (i.e., the diameter of the second neck portion 123). The width R2 of the first neck portion 113 is greater than the width R4 of the second neck portion 123, so that the second neck portion 123 can be detachably connected to the first neck portion 113 along the first axis L1. When the second bracket 120 is connected to the first bracket 110, the second neck portion 123 is connected to the first neck portion 113, and the second neck portion 123 is at least partially disposed through the first neck portion 113.

[0091] like Figure 1 As shown, the width R1 of the first head 112 is equal to the width R3 of the second head 122, so that the opposite ends of the support structure 100 have the same width. The first bracket 110 includes at least one first limiting groove 114, and the second bracket 120 includes at least one first limiting member 124. The number of the first limiting grooves 114 in this embodiment is two, Figure 1 One first limiting slot 114 is schematically shown. The number of the first limiting members 124 corresponds to the number of the first limiting slots 114 , that is, two.

[0092] The first limiting groove 114 is a groove extending from the end of the first neck 113 away from the first head 112 along the first axis L1 toward the first head 112. The first limiting member 124 is connected to the second neck 123. When the second bracket 120 is connected to the first bracket 110, at least part of the first limiting member 124 is located in the corresponding first limiting groove 114 to prevent the second bracket 120 from rotating relative to the first bracket 110, and can guide the second bracket 120 to move relative to the first bracket 110 along the first axis L1.

[0093] like Figure 1 and Figure 2As shown, the support structure 100 may optionally include an auxiliary member 140, which is detachably connected to the first neck 113 of the first bracket 110. The auxiliary member 140 includes a plurality of first auxiliary holes and a plurality of second auxiliary holes. In this embodiment, the number of the first auxiliary holes 151a, the first auxiliary holes 151b, the first auxiliary holes 151c, the first auxiliary holes 151d, and the first auxiliary holes 151e is five, and the number of the second auxiliary holes 161a, the second auxiliary holes 161b, the second auxiliary holes 161c, the second auxiliary holes 161d, and the second auxiliary holes 161e is five, but not limited thereto. These first auxiliary holes 151a, the first auxiliary holes 151b, the first auxiliary holes 151c, the first auxiliary holes 151d, and the first auxiliary holes 151e correspond to these second auxiliary holes 161a, the second auxiliary holes 161b, the second auxiliary holes 161c, the second auxiliary holes 161d, and the second auxiliary holes 161e. When the auxiliary member 140 is connected to the first bracket 110 and the second bracket 120 is connected to the first bracket 110, the first neck 113 of the first bracket 110 is located between the auxiliary member 140 and the second neck 123 of the second bracket 120. The auxiliary member 140 is used to enhance the structural strength of the supporting structure 100.

[0094] The auxiliary member 140 of this embodiment includes a first auxiliary member 150 and a second auxiliary member 160. The first auxiliary member 150 and the second auxiliary member 160 are detachably connected to the first neck 113 of the first bracket 110 along the second axis L2. When the first auxiliary member 150 and the second auxiliary member 160 are connected to the first bracket 110, at least a portion of the first bracket 110 is located between the first auxiliary member 150 and the second auxiliary member 160.

[0095] like Figure 3 and Figure 4 As shown, the first auxiliary member 150 includes a first body 152, and the first auxiliary holes 151a, 151b, 151c, 151d, and 151e are located in the first body 152 of the first auxiliary member 150 and are specifically counterbores. The second auxiliary member 160 includes a second body 162, and the second auxiliary holes 161a, 161b, 161c, 161d, and 161e are located in the second body 162 of the second auxiliary member 160 and are specifically through holes. The first body 152 and the second body 162 are semi-cylinders corresponding to the shapes of the first bracket 110 and the second bracket 120. The first auxiliary member 150 and the second auxiliary member 160 are, for example, connected to the corresponding multiple card slots B2 through multiple hooks B1. The hooks B1 are connected to the first body 152 and the card slots B2 are located in the second body 162, but are not limited thereto.

[0096] The first bracket 110 includes two second limiting members 115, the first auxiliary member 150 includes a second limiting groove 155, and the second auxiliary member 160 includes a third limiting groove 165. The two second limiting members 115 are connected to one end of the first neck 113 adjacent to the first head 112, but are not limited thereto. The two second limiting members 115 extend along the first axis L1. The second limiting groove 155 is a groove that is recessed from the inner surface 157 of the first main body 152 of the first auxiliary member 150 to the outer surface 158. The third limiting groove 165 is a groove that is recessed from the inner surface 167 of the second main body 162 of the second auxiliary member 160 to the outer surface 168. The second limiting groove 155 and the third limiting groove 165 extend along the first axis L1 corresponding to the second limiting member 115. When the auxiliary component 140 is connected to the first bracket 110 (first neck 113), one second limiting component 115 is at least partially located in the second limiting groove 155, and another second limiting component 115 is at least partially located in the third limiting groove 165 to prevent the auxiliary component 140 (first auxiliary component 150 and second auxiliary component 160) from rotating relative to the first bracket 110.

[0097] like Figure 3 and Figure 4 As shown, when the auxiliary component 140 is connected to the first bracket 110 (first neck 113) and the second bracket 120 (second neck 123) is connected to the first bracket 110, at least one of the three first alignment hole groups 111a, the first alignment hole group 111b, and the first alignment hole group 111c, at least one of the three second alignment hole groups 121a, the second alignment hole group 121b, and the second alignment hole group 121c, at least one of the five first auxiliary holes 151a, the first auxiliary holes 151b, the first auxiliary holes 151c, the first auxiliary holes 151d, and the first auxiliary holes 151e, and at least one of the five second auxiliary holes 161a, the second auxiliary holes 161b, the second auxiliary holes 161c, the second auxiliary holes 161d, and the second auxiliary holes 161e are aligned with each other to form a corresponding insertion space S1, and the spring piece 130 can be inserted into the corresponding insertion space S1. In this way, the spring piece 130 can be used to fix the first bracket 110 , the second bracket 120 and the auxiliary component 140 (the first auxiliary component 150 and the second auxiliary component 160 ).

[0098] like Figure 4As shown, each spring piece 130 includes a spring piece body 131, two spring arms 134 and two hooks 135. The two spring arms 134 are connected to the spring piece body 131, one of the hooks 135 is connected to one of the spring arms 134, and the other hook 135 is connected to the other spring arm 134. The two hooks 135 can be engaged with the auxiliary member 140. The spring piece body 131 includes a first portion 132 and a second portion 133 connected to each other. The first portion 132 corresponds to the shape and size of the first auxiliary hole 151c (first auxiliary member 150), and the second portion 133 corresponds to the shape and size of the first alignment hole group 111a (first bracket 110) and the second alignment hole group 121c (second bracket 120).

[0099] The two elastic arms 134 are connected to the second portion 133 of the spring body 131. The two elastic arms 134 have a certain elasticity. The maximum width W4 between the two elastic arms 134 corresponds to the width of the second auxiliary hole 161c. The two hooks 135 are located at one end of the elastic arms 134 away from the second portion 133 (spring body 131). The maximum width W5 between the two hooks 135 is greater than the maximum width W4 between the two elastic arms 134, and greater than the width of the second auxiliary hole 161c, so that the two hooks 135 of the spring 130 can be engaged with the second auxiliary member 160 (auxiliary member 140).

[0100] Figures 2 to 4 The support structure 100 is shown in a first state M1. Figures 2 to 4 As shown, in the first state M1, the second neck 123 of the second bracket 120 is completely inserted into the first neck 113 of the first bracket 110, and the first limiting member 124 is completely located in the first limiting groove 114 ( Figure 1 ), so that a first alignment hole group 111a and a second alignment hole group 121c are aligned on the second axis L2. The second limiting member 115 of the first bracket 110 is completely located in the second limiting groove 155 of the first auxiliary member 150, and another second limiting member 115 of the first bracket 110 is completely located in the third limiting groove 165 of the second auxiliary member 160.

[0101] The length of the first auxiliary member 150 and the second auxiliary member 160 along the first axis L1 corresponds to the length of the first neck 113 along the first axis L1, and the first neck 113 and the second neck 123 are completely located between the first auxiliary member 150 and the second auxiliary member 160. The first alignment hole group 111a, the second alignment hole group 121c, the first auxiliary hole 151c and the second auxiliary hole 161c are aligned on the second axis L2 to form an insertion space S1. A spring 130 is inserted into the corresponding insertion space S1, so that the support structure 100 is fixed in the first state M1.

[0102] like Figure 2 and Figure 3 As shown, during the process of the spring sheet 130 being inserted into the first bracket 110 (first neck 113), the second bracket 120 (second neck 123) and the auxiliary member 140 (first auxiliary member 150 and second auxiliary member 160), the two hooks 135 of the spring sheet 130 are pushed against each other by the first bracket 110, the second bracket 120, the first auxiliary member 150 and the second auxiliary member 160, thereby driving the two spring arms 134 to bend, so that the spring sheet 130 can move in the insertion space S1. When the spring sheet 130 moves to the position ( Figure 3 ), the two elastic arms 134 are reset to their own elastic force. Figure 3 In the position shown, the spring body 131 and the two spring arms 134 of the spring 130 are located in the corresponding insertion space S1, and the two hooks 135 are exposed from the second auxiliary hole 161c to the auxiliary member 140 (second auxiliary member 160) and engaged with the auxiliary member 140. In this way, the spring 130 is stably connected to the first bracket 110, the second bracket 120 and the auxiliary member 140 to fix the first bracket 110, the second bracket 120 and the auxiliary member 140.

[0103] like Figure 3 As shown, the first portion 132 of the spring body 131 is located in the first auxiliary hole 151c, and the first portion 132 abuts against the inner wall 153 of the first auxiliary hole 151c to stop the spring 130 from further moving along the second axis L2, thereby fixing the spring 130 in the Figure 3 The first portion 132 of the spring body 131 includes an outer surface 136. The curvature of the outer surface 136 corresponds to the curvature of the outer surface 158 of the first auxiliary member 150, so that the appearance of the support structure 100 can be kept beautiful. The second portion 133 of the spring body 131 extends into the first auxiliary member 150, the first bracket 110 and the second bracket 120. The two elastic arms 134 extend into the first bracket 110, the second bracket 120 and the second auxiliary member 160.

[0104] When the support structure 100 is to be switched from the first state M1 to another state (described later), the two hooks 135 of the spring sheet 130 may be forced to move closer to each other and release the engagement with the second auxiliary member 160. Then, the spring sheet 130 may be removed along the second axis L2, and the spring sheet 130 may be separated from the insertion space S1. After the spring sheet 130 is separated from the insertion space S1, the first bracket 110 and the second bracket 120 may move along the first axis L1 relative to the first auxiliary member 150 and the second auxiliary member 160, and the first bracket 110 and the second bracket 120 may move relative to each other, and the support structure 100 may be switched to the second state M2 ( Figure 5 ) or the third state M3( Figure 8 ).

[0105] like Figure 4As shown, the support structure 100 of this embodiment is cylindrical in shape as a whole. The length A1 of the support structure 100 along the first axis L1 in the first state M1 is, for example, 65 mm, and the maximum width W1 of the support structure 100 along the second axis L2 is, for example, 18 mm, but is not limited thereto. The length A1 and the maximum width W1 of the support structure 100 are the same as those of a cylindrical battery of model 18650, and can be disposed in a device (e.g., a battery box) for loading cylindrical batteries to fill the space inside the device and enhance the structural strength of the device.

[0106] For example, a commercially available battery box can hold ten cylindrical batteries of model 18650. In actual applications, depending on the needs of the user, the battery box can only hold four cylindrical batteries of model 18650. At this time, the user can install six support structures 100 in the first state M1 into the battery box to fill the idle space of the battery box and improve the structural strength of the battery box.

[0107] In addition, since the battery box fixes the cylindrical battery (support structure 100) by engaging the opposite ends of the cylindrical battery (support structure 100) through internal fixings, the support structure 100 can be stably fixed in the battery box as long as the two ends of the support structure 100 (for example, the first head 112 and the second head 123) are made to conform to the size of the two ends of the cylindrical battery.

[0108] The arrangement of the elements of the support structure 100 is not limited to this embodiment. In an embodiment not shown, the support structure may only use the first bracket 110, the second bracket 120 and the spring. The shape and size of the spring correspond to the first alignment hole group and the second alignment hole group, and can be firmly engaged with the first bracket 110 and the second bracket 120. Since the size of the first head 112 of the first bracket 110 and the size of the second head 123 of the second bracket 120 match the two ends of the cylindrical battery of model 18650, the support structure can still be set in the battery box.

[0109] Figure 5 yes Figure 1 Schematic diagram of the support structure in the second state. Figure 6 yes Figure 5 Cross-section of the supporting structure. Figure 7 yes Figure 5 Another cross-section of the support structure. Figures 5 to 7 The user can move the first bracket 110 and the second bracket 120 relatively along the first axis L1 to Figure 5, so that the support structure 100 is in the second state M2. In the second state M2, the second neck 123 of the second bracket 120 partially extends into the first neck 113 of the first bracket 110. The second stopper 115 of the first bracket 110 is partially located in the second stopper groove 155 of the first auxiliary member 150, and another second stopper 115 of the first bracket 110 is partially located in the third stopper groove 165 of the second auxiliary member 160.

[0110] like Figure 7 As shown, the first alignment hole group 111a, the second alignment hole group 121b, the first auxiliary hole 151b and the second auxiliary hole 161b are aligned to form an insertion space S2. The first alignment hole group 111b, the second alignment hole group 121c, the first auxiliary hole 151d and the second auxiliary hole 161d are aligned to form an insertion space S3. The two springs 130 are respectively inserted into the two insertion spaces S2 and S3 so that the support structure 100 can be more stably in the second state M2. The length A1 ( Figure 4 ) is smaller than the length A2 of the support structure 100 along the first axis L1 in the second state M2.

[0111] like Figure 5 As shown, the support structure 100 also includes two expansion pieces 170a. One of the expansion pieces 170a is connected to the first bracket 110, and the other expansion piece 170a is connected to the second bracket 120. Each expansion piece 170a includes an expansion body 172a and a plurality of snap-fit ​​pieces 176. The snap-fit ​​pieces 176 are connected to the expansion body 172a. The expansion body 172a is, for example, a cylinder. The number of snap-fit ​​pieces 176 is, for example, four, but is not limited thereto. The first head 112 of the first bracket 110 has a corresponding plurality of snap-fit ​​grooves 116, and the second head 123 of the second bracket 120 has a corresponding plurality of snap-fit ​​grooves 126. The engaging members 176 of the two extension members 170a are respectively engaged with the engaging grooves 116 and 126 of the first bracket 110 and the second bracket 120, so that the two extension members 170a are respectively connected to the first bracket 110 (first head 112) and the second bracket 120 (second head 122).

[0112] like Figure 7 As shown, the width R5 of the extension body 172a of the extension piece 170a along the second axis L2 (i.e., the diameter of the extension body 172a) is greater than the width R1 of the first head 112 (first bracket 110) along the second axis L2, and greater than the width R3 of the second head 123 (second bracket 120) along the second axis L2, so that the maximum width W2 of the support structure 100 along the second axis L2 can be changed. The maximum width W2 of the support structure 100 is the width R5 of the extension piece 170a.

[0113] The support structure 100 in the second state M2, in which the first bracket 110 and the second bracket 120 are engaged with the two expansion members 170a, has a length A2 along the first axis L1 of 70 mm and a maximum width W2 along the second axis L2 of 21 mm, corresponding to a cylindrical battery of model 21700. The two expansion bodies 172a of the two expansion members 170a of the support structure 100 can be engaged with the fixing member of the battery box.

[0114] In addition, in an embodiment not shown, two expansion members 170 a may be connected to the first bracket 110 and the second bracket 120 in the first state M1 , thereby changing the external dimensions of the support structure 100 .

[0115] Figure 8 Shows Figure 1 Schematic diagram of the support structure in the third state. Fig. 9 Shows Figure 8 Cross-section of the supporting structure. Fig.10 Shows Figure 8 Another cross-section of the support structure. Figures 8 to 10 The user can move the first bracket 110 and the second bracket 120 relatively along the first axis L1 to Figure 8 , so that the support structure 100 is in the third state M3. In the third state M3, the second neck 123 of the second bracket 120 partially extends into the first neck 113 of the first bracket 110.

[0116] like Fig.10 As shown, the first alignment hole group 111a, the second alignment hole group 121a, the first auxiliary hole 151a and the second auxiliary hole 161a are aligned to form an insertion space S4. The first alignment hole group 111c, the second alignment hole group 121c, the first auxiliary hole 151e and the second auxiliary hole 161e are aligned to form an insertion space S5. The two springs 130 are respectively disposed in the insertion space S4 and the insertion space S5, so that the support structure 100 can be more stably in the third state M3. The length A2 ( Figure 7 ) is smaller than the length A3 of the support structure 100 along the first axis L1 in the third state M3.

[0117] The width R6 of the expansion body 172b of the expansion piece 170b of the present embodiment along the second axis L2 (i.e., the diameter of the expansion body 172b) is greater than the width R5 ( Figure 6 ), so as to further change the maximum width W3 of the support structure 100 along the second axis L2. The maximum width W3 of the support structure 100 is the width R6 of the expansion piece 170b.

[0118] The support structure 100 in the third state M3, where the first bracket 110 and the second bracket 120 are engaged with the two expansion pieces 170b, has a length A3 along the first axis L1 of 80 mm and a maximum width W3 of 46 mm, corresponding to a cylindrical battery of model 46800. The two expansion pieces 170b of the support structure 100 can be engaged with the fixing piece of the battery box.

[0119] It can be seen that the support structure 100 can change the length of the support structure 100 along the first axis L1 by the relative movement of the first bracket 110 and the second bracket 120 along the first axis L1. The support structure 100 can change the maximum width of the support structure 100 along the second axis L2 through the expansion pieces 170a and 170b. In this way, the support structure 100 of this embodiment can have similar appearance dimensions to cylindrical batteries of model 18650, model 21700, and model 46800, and can be set in the corresponding battery box to provide good support and improve the structural strength of the battery box.

[0120] In addition, the sizes of the first bracket 110, the second bracket 120 and the auxiliary member 140 and the number of alignment holes (first alignment hole group, second alignment hole group, first auxiliary hole and second auxiliary hole) are not limited to the present embodiment, and the width of the expansion member is not limited to the present embodiment. The external dimensions that the support structure 100 can form are not limited to the present embodiment. For example, in other embodiments, the support structure can have external dimensions similar to those of cylindrical batteries of model 10400, model 14500, model 32650, etc., and can be used in corresponding battery boxes.

[0121] In summary, the second bracket of the support structure of the present application can move relative to the first bracket to change the length of the support structure along the first axis, and the support structure can be switched between multiple sizes to improve the convenience of use of the support structure. The spring sheet is used to connect the first bracket and the second bracket to fix the first bracket and the second bracket.
