Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of battery protection, and in particular to a battery protection cover and a cold chain unit. BACKGROUND

[0002] The trailer cold chain unit has a large refrigeration capacity and is usually used for long-distance transportation of trailer goods. The cold chain unit can continuously provide a stable low-temperature environment for the goods to ensure the quality and safety of the goods during long-distance transportation.

[0003] Due to the space limitation of the trailer cold chain unit, the battery pack is usually arranged below the gas-liquid separator. The gas-liquid separator can produce condensate water at low temperature, and the produced condensate water can drop onto the battery pack. The existing battery pack usually has a water baffle on the upper part. However, the water baffle cannot well protect the battery pack, and sundries (such as stones, leaves, branches, etc.) coming with the airflow are easy to collide with the battery pack, forming a safety risk. CONTENT OF THE UTILITY MODEL

[0004] The purpose of the present application is to provide a battery protection cover and a cold chain unit which can well protect the battery pack.

[0005] One aspect of the present application provides a battery protection cover. The battery protection cover is used to cover the upper surface of the battery pack, and the battery protection cover has opposite first and second surfaces. The second surface is used to cooperate with the upper surface of the battery pack, and the first surface is inclined relative to the second surface.

[0006] Further, the battery protection cover has opposite first and second sides. The first side is close to one side of the wiring terminal of the battery pack, and the second side is away from the other side of the wiring terminal. The height of the first surface at the first side is greater than the height of the first surface at the second side.

[0007] Further, the battery protection cover includes a first groove, which is provided on the first surface and extends from the first side to the second side.

[0008] Further, the battery protection cover includes a groove structure and wing plates extending outward from opposite sides of the groove structure. The groove structure has the first groove, the upper surfaces of the wing plates form the first surface, and the outer bottom surface of the groove structure forms the second surface.

[0009] Further, the wing plates and the upper surface of the battery pack have a gap therebetween.

[0010] Further, a bending portion is formed by bending downward from the outer edge of the wing plate.

[0011] Furthermore, the battery protection cover also includes a pressure plate, which is disposed in the first groove. The bottom of the pressure plate and the first groove are provided with a first mounting hole near the first side, and the bottom of the pressure plate and the first groove are provided with a second mounting hole near the second side. The first mounting hole and the second mounting hole are used to cooperate with the mounting component to fix the battery pack.

[0012] Furthermore, the battery protective cover also includes one or more second grooves, which are formed on the first surface. The second grooves are arranged in a different direction than the first grooves, and the second grooves are connected to the first grooves.

[0013] Furthermore, the second groove has a first end connected to the first groove and a second end opposite to the first end. The second groove is inclined from the second end toward the first end, and the height of the second end is greater than the height of the first end.

[0014] Another aspect of this application provides a cold chain unit. The cold chain unit includes an evaporator, a condenser, a gas-liquid separator, a power pack, a battery pack, and a battery protective cover as described above. The power pack has a compressor, and the compressor, the condenser, the evaporator, and the gas-liquid separator are connected by pipelines. The terminals of the battery pack are connected to the power pack via wires to provide power to the power pack. The gas-liquid separator is located above the battery pack, and the battery protective cover covers the upper surface of the battery pack.

[0015] The battery protection cover and cold chain unit of one or more embodiments of this application can effectively protect the battery pack of the unit, prevent condensation from contacting the battery pack, and prevent falling or splashing objects from touching the battery pack.

[0016] In addition, the battery protective cover of one or more embodiments of this application adopts a groove structure and wing plates extending outward from opposite sides of the groove structure, thereby allowing a gap between the wing plates and the upper surface of the battery pack. This allows the airflow from the condenser fan passing through the power pack to fully sweep over the battery pack without hindering battery heat dissipation and without affecting the overall performance of the battery pack.

[0023] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses consistent with some aspects of this application as detailed in the appended claims.

[0024] The battery protection cover and cold chain unit of this application will be described in detail below with reference to the accompanying drawings. Unless otherwise specified, the features of the following embodiments and implementation methods can be combined with each other.

[0025] This application provides a cold chain unit. The cold chain unit 1 can be, for example, a trailer-mounted cold chain unit. Figure 1 A partial schematic diagram of a cold chain unit 1 according to an embodiment of this application is shown. Figure 1 As shown, a cold chain unit 1 according to one embodiment of this application includes an evaporator 10, a condenser 20, a gas-liquid separator 30, a power pack 40, a battery pack 50, and a battery protection cover 60. The cold chain unit 1 includes a metal frame 70, and the evaporator 10, condenser 20, gas-liquid separator 30, power pack 40, and battery pack 50 are all mounted on the metal frame 70 of the cold chain unit 1.

[0026] The power pack 40 includes a compressor, and the compressor, condenser 20, evaporator 10, and gas-liquid separator 30 can be connected via piping. The battery pack 50 has wiring terminals 51 (e.g., ...). Figure 2 As shown, the terminal 51 of the battery pack 50 can be connected to the power pack 40 via a wire to provide power to the power pack 40. The gas-liquid separator 30 is located above the battery pack 50. A battery protective cover 60 covers the upper surface of the battery pack 50 to effectively protect it.

[0027] The cold chain unit 1 of this application can provide good protection for the battery pack 50 by using a battery protection cover 60 to cover the upper surface of the battery pack 50.

[0028] The following will combine Figures 2 to 6 The structure of the battery protection cover 60 of this application will be described in detail below.

[0029] Figure 2 This application discloses a perspective view showing a battery protective cover 60 mounted on a battery pack 50 according to one embodiment of the present application. Figure 3 Revealed Figure 2 The side view shown depicts the battery cover 60 mounted on the battery pack 50. Figure 4 Revealed Figure 2 The sectional view shown is along line AA. Figure 5 Revealed Figure 2 The battery cover 60 shown is mounted on the battery pack 50 in another side view. Figure 6 A perspective view of a battery protective cover 60 according to an embodiment of this application is shown.

[0030] like Figure 2 and 3 As shown, a battery protective cover 60 according to one embodiment of this application has a first surface 601 and a second surface 602 facing each other. The second surface 602 is used to mate with the upper surface of the battery pack 50, and the first surface 601 is inclined relative to the second surface 602. Optionally, the second surface 602 is disposed along a horizontal plane, and the first surface 601 has an inclination angle of 5 degrees relative to the horizontal plane.

[0031] The battery cover 60 of this application is designed to effectively drain water from its upper surface by tilting the first surface 601.

[0032] The battery cover 60 has a first side 603 and a second side 604, with the first side 603 closer to the terminal 51 of the battery pack 50 and the second side 604 farther from the terminal 51. In some embodiments, the height of the first surface 601 of the battery cover 60 at the first side 603 is greater than the height of the first surface 601 at the second side 604. This allows condensate generated by the gas-liquid separator 30 to be directed to the side of the battery pack 50 without the terminal 51, preventing condensate from flowing onto the terminal 51 and causing corrosion.

[0033] like Figure 2 and Figure 5As shown, the battery cover 60 includes a first groove 610, which is formed on the first surface 601 of the battery cover 60. The first groove 610 is arranged along the direction from the first side 603 to the second side 604 of the battery cover 60. The first groove 610 not only guides water flow but also acts as a reinforcing rib.

[0034] like Figure 2 As shown, in some embodiments, the battery cover 60 of this application further includes a pressure plate 64, which is disposed in the first groove 610. The pressure plate 64 is, for example, a metal pressure plate, to enhance its strength.

[0035] The bottom of the pressure plate 64 and the first groove 610 is provided with a first mounting hole (not labeled) at a position near the first side 603, and the bottom of the pressure plate 64 and the first groove 610 is provided with a second mounting hole at a position near the second side 604. The first mounting hole and the second mounting hole can cooperate with the mounting component (e.g., the fixing screw nut 65). Through the cooperation of the first groove 610 and the pressure plate 64 with the fixing screw nut 65, the battery pack 50 can be completely fixed and prevented from sliding.

[0036] Optionally, the battery protection cover 60 of this application can be an insulator, such as an ABS plastic part, which can block the pressure plate 64 from the battery pack 50, prevent leakage hazards, and avoid the risk of the battery pack 50 being crushed by the pressure plate 64.

[0037] like Figure 2 and Figure 6 As shown, in some embodiments, the battery cover 60 further includes one or more second grooves 620. The second grooves 620 are formed on the first surface 601, and the orientation of the second grooves 620 is different from that of the first grooves 610. Furthermore, the second grooves 620 are connected to the first grooves 610. The second grooves 620 can act as reinforcing ribs, thus strengthening the battery cover 60.

[0038] like Figure 4 As shown, in some embodiments, the second groove 620 has a first end communicating with the first groove 610 and a second end opposite to the first end. The second groove 620 is inclined from the second end toward the first end, and the height of the second end is greater than the height of the first end. Optionally, the second groove 620 has an inclination angle of 4 degrees relative to the horizontal direction.

[0039] The battery cover 60 of this application is tilted so that some water flow on the upper surface of the battery cover 60 can be introduced into the first groove 610 through the second groove 620 and then led out from the first groove 610. This concentrates the water flow on the upper surface of the battery cover 60 and leads it out from the first groove 610 to the side of the battery cover 60 away from the terminal 51 of the battery pack 50. This can better lead the water flow on the upper surface of the battery cover 60 to the outside of the battery pack 50, and provide better protection for the terminal 51 of the battery pack 50.

[0040] The battery protection cover 60 of this application has a first groove 610 and a second groove 620. The first groove and the second groove form a horizontal and vertical water guiding channel, which can lead the water flow on the upper surface of the battery protection cover 60 to the outside of the battery pack 50, and can provide good protection for the wiring terminals 51 of the battery pack 50. In addition, the first groove 610 and the second groove 620 can form a reinforcing rib to ensure that the battery protection cover 60 has sufficient strength to block the debris blown into the machine body with the airflow.

[0041] In some embodiments, the battery cover 60 includes a groove structure 61 and a pair of wing plates 62 extending outward from opposite sides of the groove structure 61. The groove structure 61 has a first groove 610 and a second groove 620 formed on the wing plates 62. In addition, the upper surface of the wing plates 62 forms a first surface 601, and the outer bottom surface of the groove structure 61 forms a second surface 602.

[0042] The battery protective cover 60 of this application employs a groove structure 61 and wing plates 62 extending outward from opposite sides of the groove structure 61, thereby allowing a gap between the wing plates 62 and the upper surface of the battery pack 50. This ensures sufficient clearance between the battery protective cover 60 and the battery pack 50.

[0043] like Figure 5 As shown, since there is a sufficient gap between the battery protection cover 60 and the battery pack 50, the airflow from the condenser fan passing through the power pack 40 can fully sweep over the battery pack 50 to dissipate heat from the battery pack 50 without affecting the overall performance of the battery pack 50.

[0044] In some embodiments, a bend 63 is formed by bending downwards from the outer edge of the wing 62. This can improve the structural strength of the battery cover 60.

[0045] The battery protection cover 60 of this application has a novel design. The design of the first groove 610 and the second groove 620 can not only draw condensate away from the battery pack 50, but also act as reinforcing ribs to improve the strength of the battery protection cover 60 body and provide good protection for the battery pack 50.

[0046] The battery protection cover 60 of this application is designed with the usage environment of the battery pack 50 in mind, and reserves sufficient space for heat dissipation of the battery pack 50, so as not to affect the performance of the battery pack 50 itself.

[0047] The battery protection cover 60 of this application can be injection molded from ABS plastic, which is not only lightweight and of moderate strength, but also effectively isolates the battery pack 50 from the pressure plate 64 used for fixing, thus avoiding the risk of leakage.

[0048] The battery protective cover and cold chain unit provided in the embodiments of this application have been described in detail above. Specific examples have been used to illustrate the battery protective cover and cold chain unit of this application. The descriptions of the embodiments above are only for helping to understand the core ideas of this application and are not intended to limit this application. It should be noted that those skilled in the art can make several improvements and modifications to this application without departing from the spirit and principles of this application, and all such improvements and modifications should fall within the protection scope of the appended claims.
