Description

Technical Field

[0001] The utility model belongs to the technical field of electronic equipment, and in particular relates to a battery cover and a communication box. Background Art

[0002] With the development of in-vehicle electronic products, more and more industries need to use remote interaction and wireless communication technologies. Therefore, there are more and more communication tools based on wireless communication terminals, such as in-vehicle wireless terminal TBOX, drone operating handles, etc. Regardless of the type of wireless communication box, a battery pack must be installed inside.

[0003] Taking the vehicle-mounted wireless terminal TBOX as an example, the existing wireless TBOX generally installs the battery pack in the battery compartment of the box body, and then covers the battery compartment with a battery cover to protect the battery. Due to the influence of production errors, when the battery pack and the battery compartment are assembled, there will inevitably be an assembly gap, which makes the battery pack easy to shake. To solve the shaking problem, the existing technology generally fills foam or sponge in the battery compartment, but due to the size of the wireless TBOX, the amount of foam or sponge filled is limited. At the same time, the elastic force provided by the foam or sponge is unstable. In the use scenario with high shaking intensity, such as off-road driving or sudden braking of the car, despite the filling of foam or sponge, the battery pack will still collide with the compartment wall of the battery compartment, resulting in a greatly increased probability of damage to the battery pack. Moreover, the additional use of foam or sponge will cause additional production cost expenditure. Utility Model Content

[0004] In view of the above-mentioned defects or shortcomings, the utility model provides a battery cover and a communication box, aiming to solve the technical problems that the battery anti-sway design of the existing wireless communication box has poor stability and causes additional cost expenditure.

[0005] To achieve the above-mentioned purpose, the utility model provides a battery cover, which includes a cover body and an elastic buckle pair. A battery accommodating cavity is formed on the inner side of the cover body. The elastic buckle pair includes a first buckle and a second buckle which are respectively arranged on two opposite edges of the battery accommodating cavity. The top ends of the first buckle and the second buckle are respectively arranged toward the opposite sides of the battery accommodating cavity, and the top ends of the first buckle and the second buckle extend toward the top of the cavity opening of the battery accommodating cavity.

[0006] In an embodiment of the utility model, the first buckle includes a main body portion and an elastic clamping portion. The main body portion is arranged at the edge of the battery accommodating cavity as a cavity side wall of the battery accommodating cavity. The elastic clamping portion is arranged at the top end of the main body portion and is inclined toward the edge of the battery accommodating cavity on the opposite side. The elastic clamping portion extends obliquely from the bottom end to the top end toward the cavity opening of the battery accommodating cavity.

[0007] In an embodiment of the utility model, the battery cover further comprises a wall body protruding from the inner side surface of the cover body, and the wall body and the body part serve as cavity side walls of the battery accommodating cavity and are used to jointly enclose and form the battery accommodating cavity.

[0008] To achieve the above objectives, the utility model also provides a communication box, wherein the communication box includes the battery cover and a box body as described above, the box body is provided with a docking cavity for docking with the battery accommodating cavity, and the docking cavity is larger than the battery accommodating cavity.

[0009] In an embodiment of the utility model, a protruding edge is provided on the box body, and the edge is formed to form a docking cavity. The inner side of the cover body is also provided with a cover brim, which is located outside the edge of the battery accommodating cavity and is spaced from the edge of the battery accommodating cavity to form an insertion gap. The insertion gap is used for the edge to extend into when the cover body is inverted in the docking cavity.

[0010] In an embodiment of the utility model, a protruding limiting portion is further provided on the inner side surface of the cover body, the limiting portion is located in the extending gap, and a positioning structure for limiting and cooperating with the limiting portion is further provided on the top end of the peripheral edge.

[0011] In an embodiment of the utility model, the positioning structure is a step arranged at the top end of the peripheral edge, and the step cooperates with the step-limiting portion of the limiting portion.

[0012] In an embodiment of the utility model, the outer side surface of the cover body is aligned with the area of ​​the limiting part and is sunken. The limiting part is also provided with a threaded connection hole, which passes through the limiting part and the inner and outer sides of the cover body; wherein, through the step and the step limiting cooperation of the limiting part, the threaded connection hole can be aligned with the connection hole on the box body.

[0013] In an embodiment of the utility model, a cover body mounting portion is provided on the box body, the cover body mounting portion is sunken to form a sunken mounting cavity, the surrounding edge is arranged in the sunken mounting cavity and is spaced from the side wall of the sunken mounting cavity to form a drainage groove, and the drainage groove is used for the cover eaves on the cover body to extend into when the cover body is inverted in the docking cavity.

[0014] In an embodiment of the utility model, the cavity side wall of at least one side of the sunken installation cavity sinks to form a drainage overflow port, which extends to the edge of the box body, and the height of the drainage overflow port is lower than the height of the peripheral edge.

[0015] Through the above technical solution, the battery cover provided by the embodiment of the utility model has the following beneficial effects:

[0016] Since the top ends of the first buckle and the second buckle extend toward the opposite side and extend to the top of the opening of the battery accommodating cavity, the size of the opening of the battery accommodating cavity will gradually shrink toward the opposite side to form a neck-like structure. When the battery pack is placed in the battery accommodating cavity, the size of the upper end of the battery pack will be larger than the distance from the top end of the first buckle to the top end of the second buckle. At this time, the battery pack will squeeze the first buckle and the second buckle to cause elastic deformation of the top ends of the first buckle and the second buckle. The elastic deformation of the first buckle and the second buckle will press the battery pack toward the opposite side and downward, thereby achieving elastic clamping and fixing of the battery pack to prevent the battery pack from shaking in the battery accommodating cavity. When the battery pack needs to be replaced, it is only necessary to remove the battery cover from the box body, and then use a tool to pry the elastic buckle pair to remove the battery pack from the battery accommodating cavity. Disassembly is very convenient. In summary, the battery cover in the utility model uses an elastic snap pair to limit and clamp the battery. Compared with the existing foam or sponge, it can provide a more stable elastic force, reduce the use of additional materials, and reduce production costs. At the same time, the installation position of the battery pack is set on the battery cover, which can facilitate the disassembly and assembly of the battery pack.

[0034] The specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0035] The battery cover of the present utility model is described below with reference to the accompanying drawings.

[0036] The utility model provides a battery cover, such as Figure 1 and Figure 2 As shown, the battery cover includes:

[0037] A housing body 1, wherein a battery receiving chamber 11 is formed inside the housing body 1; and

[0038] The elastic buckle pair 2 includes a first buckle 21 and a second buckle 22 which are respectively arranged at two opposite edges of the battery accommodating cavity 11. The top ends of the first buckle 21 and the second buckle 22 are respectively arranged toward the opposite sides of the battery accommodating cavity 11, and the top ends of the first buckle 21 and the second buckle 22 extend toward the top of the cavity opening of the battery accommodating cavity 11.

[0039] Since the top ends of the first clip 21 and the second clip 22 extend toward the opposite sides respectively and the top ends extend to above the cavity opening of the battery accommodating cavity 11, the cavity opening size of the battery accommodating cavity 11 will gradually shrink toward the opposite side to form a necking-like structure. When the battery pack is placed in the battery accommodating cavity 11, the size of the upper end of the battery pack will be larger than the distance from the top end of the first clip 21 to the top end of the second clip 22. At this time, the battery pack will squeeze the first clip 21 and the second clip 22 to cause the top ends of the first clip 21 and the second clip 22 to undergo elastic deformation. The elastic deformation of the first clip 21 and the second clip 22 will press the battery pack toward the opposite side and downward, thereby achieving elastic clamping and fixation of the battery pack. Compared with foam or sponge, the elastic clamping force provided by the clip is more stable, thereby preventing the battery pack from shaking in the battery accommodating cavity 11 even in extreme environments. When the battery pack needs to be replaced, the battery cover only needs to be removed from the box body 4, and then the elastic buckle pair 2 is pried out with a tool to remove the battery pack from the battery accommodating cavity 11, which is very convenient to disassemble. In summary, the battery cover in the utility model uses the elastic buckle pair 2 to limit and clamp the battery, which can provide a more stable elastic force compared to the existing foam or sponge, and can reduce the use of additional materials and reduce production costs. At the same time, the installation position of the battery pack is set on the battery cover, which can facilitate the disassembly and assembly of the battery pack.

[0040] It should be noted that pressing downward refers to pressing toward the inner side of the cover body 1, the bottom of the buckle refers to the side of the buckle close to the inner side of the cover body 1, and the top of the buckle refers to the side away from the inner side of the cover body 1. The first buckle 21 and the second buckle 22 are preferably made of PP+GF30 (polypropylene with 30% glass fiber content), which can provide more stable elastic force and have stronger structural strength.

[0041] like Figure 1 As shown, in the embodiment of the utility model, the first buckle 21 includes a main body 211 and an elastic clamping portion 212. The main body 211 is arranged at the edge of the battery accommodating cavity 11 as the cavity side wall of the battery accommodating cavity 11. The elastic clamping portion 212 is arranged at the top of the main body 211 and is inclined toward the edge of the battery accommodating cavity 11 on the opposite side. The elastic clamping portion 212 extends obliquely from the bottom to the top toward the cavity opening of the battery accommodating cavity 11. The main body 211 can be arranged vertically, and the elastic clamping portion 212 as the folded edge of the first buckle 21 can be inclined toward the opposite side. Such a design can better wrap the battery pack. In the assembly posture, after the battery pack squeezes the elastic clamping portion 212 to deform and expand outward, the elastic clamping portion 212 can provide a stable clamping force, thereby limiting the shaking of the battery pack. Of course, the first buckle 21 can also be arranged to be inclined toward the opposite side as a whole.

[0042] In an embodiment of the present invention, the elastic clamping portion 212 may be in a straight plate shape or in an arc shape, and may be specifically set according to the side contour of the battery pack. By adaptively changing the shape of the elastic clamping portion 212, the battery pack may be better wrapped.

[0043] like Figure 1 As shown, in the embodiment of the present utility model, the structure of the second buckle 22 can be the same as that of the first buckle 21 .

[0044] like Figure 1 As shown, in the embodiment of the present utility model, the number of the first buckle 21 and the second buckle 22 can be plural respectively, and the two sets of opposite edges of the battery receiving cavity 11 can be provided with elastic buckle pairs 2.

[0045] like Figure 1 As shown, in the embodiment of the utility model, the battery cover also includes a wall 31 protruding from the inner side of the cover body 1, and the wall 31 and the body 211 are used as the side walls of the battery receiving cavity 11 to jointly enclose the battery receiving cavity 11. That is, the battery receiving cavity 11 is formed by the wall 31 and the body 211, and the material of the wall 31 can be the same as that of the buckle. By providing the wall 31, the battery receiving cavity 11 can be insulated to prevent the heat generated by the electronic components in the communication box from being transferred to the battery receiving cavity and affecting the performance and life of the battery pack.

[0046] like Figure 1 , Figure 3 and Figure 4 As shown, to achieve the above purpose, the utility model also provides a communication box, wherein the communication box includes the battery cover and the box body 4 according to the above, and the box body 4 is provided with a docking cavity 41 for docking with the battery accommodating cavity 11, and the docking cavity 41 is larger than the battery accommodating cavity 11. The communication box can be a wireless TBOX, or a wireless control handle box, etc.

[0047] Taking the wireless TBOX as an example, the box body 4 of the wireless TBOX is generally made of metal, and a docking cavity 41 for docking with the battery receiving cavity 11 is provided on the box body 4. During assembly, the battery pack is first installed in the battery receiving cavity 11 of the battery cover, and the battery pack will be limited and clamped under the clamping force of the first buckle 21 and the second buckle 22, thereby preventing the battery pack from shaking relative to the cover body 1. After the battery is clamped, it is only necessary to invert the battery cover with the battery pack on the docking cavity 41, and then fix it with the box body 4 through threaded fasteners to complete the battery installation of the communication box. Since the battery cover is fixedly connected to the box body 4, the battery cover is always fixed relative to the box body 4, and the battery pack is fixed in the battery receiving cavity 11 through buckle clamping, thereby preventing the battery pack from shaking relative to the box body 4. Among them, a bottom bracket 46 can be set in the docking cavity 41 to support the battery pack when the battery cover is inverted. The bottom bracket 46 can reduce the load of the buckle and ensure the stability of the buckle clamping. After the battery accommodating cavity 11 and the docking cavity 41 are correctly aligned, the wall 31 and the buckle used to surround the side wall of the battery accommodating cavity 11 will extend into the docking cavity 41, thereby realizing the separation of the battery accommodating cavity 11 and the docking cavity 41. This separation design can effectively insulate the battery pack.

[0048] like Figure 1 , Figure 3 and Figure 4 As shown, in the embodiment of the utility model, the box body 4 is provided with a protruding edge 42, and the edge 42 is arranged to form a docking cavity 41. The inner side of the cover body 1 is also provided with a cover brim 12, and the cover brim 12 is located outside the edge of the battery accommodating cavity 11 and is spaced from the edge of the battery accommodating cavity 11 to form an insertion gap 32, and the insertion gap 32 is used for the edge 42 of the docking cavity 41 to be inserted when the cover body 1 is inverted on the docking cavity 41. The waterproof performance of the battery accommodating cavity 11 can be increased by the inverted staggered cooperation between the cover brim 12 and the edge 42 on the box body 4. At the same time, the existence of the insertion gap 32 can also increase the heat insulation performance of the battery pack, and further reduce the influence of the high temperature residual heat in the box body 4 on the performance of the battery pack.

[0049] like Figure 3 As shown, in the embodiment of the present invention, the bottom surface of the docking cavity 41 can be hollowed out to facilitate wiring and save materials.

[0050] like Figure 1 , Figure 3 and Figure 4As shown, in an embodiment of the utility model, a cover body mounting portion is provided on the box body 4, the cover body mounting portion is sunken to form a sunken mounting cavity 43, the peripheral edge 42 is arranged in the sunken mounting cavity 43 and is spaced from the cavity side wall of the sunken mounting cavity 43 to form a drainage groove 44, and the drainage groove 44 is used for the cover brim 12 on the cover body 1 to extend into when the cover body 1 is inverted in the docking cavity 41. Some communication boxes need to work outdoors, so the communication boxes need to have certain waterproof performance. The communication box in the utility model is provided with a canopy 12 on the battery cover and a peripheral edge 42 on the box body 4, and then the matching relationship between the two is set to be an inverted staggered match. When rainwater drops onto the surface of the communication box, it can be prevented from seeping into the battery accommodating cavity 11. At the same time, a drainage groove 44 is provided between the cavity side wall of the sunken installation cavity 43 and the peripheral edge 42 on the box body 4, rainwater dripping on the outer surface of the battery cover can be diverted into the drainage groove 44, thereby facilitating the centralized discharge of rainwater and preventing rainwater from seeping into the gap between the canopy 12 and the peripheral edge 42.

[0051] like Figure 3 and Figure 4 As shown, in the embodiment of the utility model, a sunken installation cavity 43 is provided to reduce the height of the battery cover protruding from the box body 4 after installation, thereby realizing a completely flat design of the communication box surface.

[0052] It should be noted that the height between the eaves 12 and the edge 42 needs to be sufficient, that is, the depth of the drainage groove 44 needs to be sufficient to prevent the drainage groove 44 from being too deep and causing rainwater to penetrate.

[0053] like Figure 3 and Figure 4 As shown, in the embodiment of the utility model, the side wall of at least one side of the sinking installation cavity 43 is concave and forms a drainage overflow port 45, which extends to the edge of the box body 4, and the height of the drainage overflow port 45 is lower than the height of the surrounding edge 42. When the water in the drainage groove 44 accumulates to a certain depth, it will flow out from the drainage overflow port 45, thereby preventing rainwater from accumulating too much and infiltrating from the gap between the eaves 12 and the surrounding edge 42. The design of the drainage overflow port 45 can also ensure that the battery accommodating cavity 11 can maintain waterproof performance when the communication box is tilted at a preset angle in all directions, thereby meeting the waterproof standards in the industry. Moreover, one side wall of the sinking installation cavity 43 is designed to be shorter, which can save materials.

[0054] In the embodiment of the utility model, an opening is further provided on the cavity side wall of at least one side of the sunken installation cavity 43 . The opening design is not only convenient for drainage, but also convenient for taking the battery cover out of the sunken installation cavity 43 .

[0055] like Figure 1 and Figure 3As shown, in the embodiment of the utility model, the inner side surface of the cover body 1 is further provided with a protruding limiting portion 33, the limiting portion 33 is located in the extending gap 32, and the top end of the peripheral edge 42 is further provided with a positioning structure for limiting and cooperating with the limiting portion 33. Specifically, the cover body 1 and the box body 4 are generally provided with threaded connection holes 5 to facilitate the installation of the battery cover, and through the cooperation of the limiting portion 33 and the positioning structure, the connection holes on the cover body 1 and the box body 4 can be accurately aligned, thereby further facilitating the rapid installation of the battery cover.

[0056] like Figure 3 As shown, in the embodiment of the utility model, the positioning structure can be a raised step 421 arranged at the top of the peripheral edge 42, and the step 421 and the limiting portion 33 can cooperate in step limiting, and the step 421 can not only realize the rapid alignment of the threaded connection hole 5, but also increase the height of the peripheral edge 42, and improve the waterproof performance of the battery accommodating cavity 11. Of course, the positioning structure can also be a blocking block, a positioning groove, etc.

[0057] like Figure 2 and Figure 3 As shown, in the embodiment of the utility model, the outer side surface of the cover body 1 is aligned with the area of ​​the limiting portion 33 and is sunken, and the limiting portion 33 is also provided with a threaded connection hole 5, which is set through the limiting portion 33 and the inner and outer sides of the cover body 1; wherein, through the step 421 and the step limiting cooperation of the limiting portion 33, the threaded connection hole 5 can be aligned with the connection hole on the box body 4. By sinking the area where the threaded connection hole 5 is set, when the battery cover and the box body 4 are installed by bolts, the head of the bolt can be prevented from protruding from the outer side surface of the cover body 1, thereby ensuring the flatness of the outer side surface of the cover body 1.
